Description

TECHNICAL FIELD

This disclosure relates generally to image capture devices, and more specifically, to a system of heatsinks used in image capture devices.

BACKGROUND

Photography during physical activity has been improved by use of simple-to-operate, lightweight, compact cameras (or other image capture devices). Advancements in technology have allowed for more functionality and faster components to be added to the cameras, allowing for clearer images and video to be captured. Additionally, cameras have become sealed so that the cameras may be splashed, submerged, or otherwise inundated with water without impacting performance. Camera components can be tightly packed together within a sealed housing for a smaller, more user-friendly camera. Consequently, the tightly-packed components retain heat that can interfere with performance of the various components and cause an increase in thermal loads within the camera, which can negatively impact camera performance. Thus, a heat system that mitigates thermal loads within a camera that is sealed would be useful.

SUMMARY

Disclosed herein are implementations of a heatsink for an image capture device.

One aspect includes an image capture device including a first component configured to provide thermal energy. A heatsink is spaced a distance apart from the first component, and a second component is positioned between the first component and the heatsink. A conductor contacts the first component and the heatsink, and the conductor extends from the first component along sides of the second component to the heatsink.

Another aspect includes an image capture device including a heatsink, a printed circuit board configured to provide thermal energy, and first and second components separating the printed circuit board and the heatsink. A conductor facilitates management of thermal energy and connects the printed circuit board and the heatsink by extending along sides of the first component and between the first component and the second component.

Another aspect includes an image capture device including a first heatsink, a second heatsink, and a printed circuit board configured to provide thermal energy and positioned between the first heatsink and the second heatsink. A component separates the first heatsink and the printed circuit board, and a conductor facilitates movement of thermal energy and extends along sides of the component to connect the printed circuit board, the first heatsink, and the second heatsink.

DETAILED DESCRIPTION

As more components and processing power are added to image capture devices, more heat is added to the image capture devices. Improved thermal management of the image capture device becomes important to provide for extended use of the image capture device. Management of heat with and along a heatsink may allow for extended use of an image capture device before the heat retained within the image capture device impacts operation or before components become potentially damaged. The heatsink may balance heat from components by connecting the heatsink and heat producing component with a conductor that circumvents intervening components so that heat is transferred over a long distance within the camera or from a first region of the camera to a second region of the camera. The conductor can connect two components with the heat producing component such that heat is balanced between a front heatsink and a rear heatsink. Further, the heatsink may act as a barrier between components that provide electromagnetic signals so that the heatsink blocks electromagnetic signals and performance of the components is not reduced or adversely effected.

FIGS. 1A-B are isometric views of an example of an image capture device 100. The image capture device 100 may include a body 102, a lens 104 structured on a front surface of the body 102, various indicators on the front surface of the body 102 (such as light-emitting diodes (LEDs), displays, and the like), various input mechanisms (such as buttons, switches, and/or touch-screens), and electronics (such as imaging electronics, power electronics, etc.) internal to the body 102 for capturing images via the lens 104 and/or performing other functions. The lens 104 is configured to receive light incident upon the lens 104 and to direct received light onto an image sensor internal to the body 102. The image capture device 100 may be configured to capture images and video and to store captured images and video for subsequent display or playback.

The image capture device 100 may include an LED or another form of indicator 106 to indicate a status of the image capture device 100 and a liquid-crystal display (LCD) or other form of a display 108 to show status information such as battery life, camera mode, elapsed time, and the like. The image capture device 100 may also include a mode button 110 and a shutter button 112 that are configured to allow a user of the image capture device 100 to interact with the image capture device 100.

The door 114 may also include a seal 120 and a battery interface 122. When the door 114 is an open position, access is provided to an input-output (I/O) interface 124 for connecting to or communicating with external devices as described below and to a battery receptacle 126 for placement and replacement of a battery (not shown). The battery receptacle 126 includes operative connections (not shown) for power transfer between the battery and the image capture device 100. When the door 114 is in a closed position, the seal 120 engages a flange (not shown) or other interface to provide an environmental seal, and the battery interface 122 engages the battery to secure the battery in the battery receptacle 126. The door 114 can also have a removed position (not shown) where the entire door 114 is separated from the image capture device 100, that is, where both the hinge mechanism 116 and the latch mechanism 118 are decoupled from the body 102 to allow the door 114 to be removed from the image capture device 100.

The image capture device 100 may include a microphone 128 on a front surface and another microphone 130 on a side surface.

In the present example, the exterior includes six surfaces (i.e. a front face, a left face, a right face, a back face, a top face, and a bottom face) that form a rectangular cuboid. Furthermore, both the front and rear surfaces of the image capture device 100 are rectangular. In other embodiments, the exterior may have a different shape. The image capture device 100 may be made of a rigid material such as plastic, aluminum, steel, or fiberglass. The image capture device 100 may include features other than those described here. For example, the image capture device 100 may include additional buttons or different interface features, such as interchangeable lenses, cold shoes, and hot shoes that can add functional features to the image capture device 100.

The image capture device 100 may interface with or communicate with an external device, such as an external user interface device (not shown), via a wired or wireless computing communication link (e.g., the I/O interface 124). Any number of computing communication links may be used. The computing communication link may be a direct computing communication link or an indirect computing communication link, such as a link including another device or a network, such as the internet, may be used.

In some implementations, the computing communication link may be a Wi-Fi link, an infrared link, a Bluetooth (BT) link, a cellular link, a ZigBee link, a near field communications (NFC) link, such as an ISO/IEC 20643 protocol link, an Advanced Network Technology interoperability (ANT+) link, and/or any other wireless communications link or combination of links.

The external user interface device may display, or otherwise present, content, such as images or video, acquired by the image capture device 100. For example, a display of the external user interface device may be a viewport into the three-dimensional space represented by the panoramic images or video captured or created by the image capture device 100.

The external user interface device may communicate information, such as metadata, to the image capture device 100. For example, the external user interface device may send orientation information of the external user interface device with respect to a defined coordinate system to the image capture device 100, such that the image capture device 100 may determine an orientation of the external user interface device relative to the image capture device 100.

Based on the determined orientation, the image capture device 100 may identify a portion of the panoramic images or video captured by the image capture device 100 for the image capture device 100 to send to the external user interface device for presentation as the viewport. In some implementations, based on the determined orientation, the image capture device 100 may determine the location of the external user interface device and/or the dimensions for viewing of a portion of the panoramic images or video.

The external user interface device may implement or execute one or more applications to manage or control the image capture device 100. For example, the external user interface device may include an application for controlling camera configuration, video acquisition, video display, or any other configurable or controllable aspect of the image capture device 100.

The user interface device, such as via an application, may generate and share, such as via a cloud-based or social media service, one or more images, or short video clips, such as in response to user input. In some implementations, the external user interface device, such as via an application, may remotely control the image capture device 100 such as in response to user input.

In some implementations, the external user interface device, such as via an application, may mark one or more key moments contemporaneously with capturing the images or video by the image capture device 100, such as with a tag or highlight in response to a user input or user gesture.

The external user interface device, such as via an application, may display or otherwise present marks or tags associated with images or video, such as in response to user input. For example, marks may be presented in a camera roll application for location review and/or playback of video highlights.

The external user interface device, such as via an application, may wirelessly control camera software, hardware, or both. For example, the external user interface device may include a web-based graphical interface accessible by a user for selecting a live or previously recorded video stream from the image capture device 100 for display on the external user interface device.

The external user interface device may receive information indicating a user setting, such as an image resolution setting (e.g., 3840 pixels by 2160 pixels), a frame rate setting (e.g., 60 frames per second (fps)), a location setting, and/or a context setting, which may indicate an activity, such as mountain biking, in response to user input, and may communicate the settings, or related information, to the image capture device 100.

In some embodiments, the image capture device 200 described herein includes features other than those described. For example, instead of the I/O interface and the interactive display 224, the image capture device 200 may include additional interfaces or different interface features. For example, the image capture device 200 may include additional buttons or different interface features, such as interchangeable lenses, cold shoes, and hot shoes that can add functional features to the image capture device 200.

The processing apparatus 320 may include one or more processors having single or multiple processing cores. In some implementations, the processing apparatus 320 may include an application specific integrated circuit (ASIC). For example, the processing apparatus 320 may include a custom image signal processor. The processing apparatus 320 may exchange data (e.g., image data) with other components of the image capture device 300, such as the image sensor(s) 312, via the bus 380.

FIG. 4 is a top view of a heat system 402 used inside of an image capture device, such as the image capture devices 100, 200 of FIGS. 1A-2B. The heat system 402 may be enclosed by a body of an image capture device, such as the body 102 of FIG. 1A, so that the heat system 402 and the body are a closed system. The heat system 402 includes a printed circuit board (PCB) 406 and a component 408 that are centrally located relative to a first heatsink 412 and a second heatsink 414 so that the heatsinks 412, 414 surround the PCB 406 and the component 408. To distribute evenly or otherwise balance thermal energy throughout the heat system 402, the first heatsink 412 and the second heatsink 414 are located on opposing sides of or otherwise separated by the PCB 406 and the component 408 so that each provide thermal energy. The second heatsink 414 and the PCB 406 may be linked by one or more locator pins (not shown) to stabilize the PCB 406 and/or facilitate movement or management of thermal energy between the second heatsink 414 and the PCB 406 by conduction.

Between the heatsinks 412, 414, the PCB 406 and/or the component 408 is configured to provide or generate thermal energy. When providing thermal energy for the heat system 402, the PCB 406 and/or the component 408 may include one or more additional components (not shown) that are configured to provide or generate thermal energy. For example, the component(s) associated with the PCB 406 or the component 408 may include a processor, a module, a battery, an input-output interface, a battery cage, an image processor, a RAM device, a card controller, an analog/digital converter, a card slot, a GPS system, a combination thereof, or any other component that provides thermal energy during operation of the component(s). If the component 408 is a battery or other connectable component, the component 408 may be readily disconnected from the heat system 402 without interfering with the conductors 418, 420 or the heatsinks 412, 414, for example, using a door such as the door 114 of FIG. 1A. Any component, the PCB 406, the component 408, or other circuit, as described herein, may be described as a first component, a second component, a third component, or a fourth component for clarity.

In the heat system 402, the heatsinks 412, 414 function as a passive heat exchanger that may receive thermal energy for transferring or dissipating via conduction or convection. The heatsinks 412, 414 may be entirely located within a housing or a body or portions thereof may extend outside of the housing or the body. The heatsinks 412, 414 may individually or in combination have a threshold predetermined mass capacity that is an amount of thermal energy that can be received to balance the thermal energy distributed in the heat system 402. The heatsinks 412, 414 may be configured to dissipate thermal energy emitting from any component that provides thermal energy, including the PCB 406 and/or the component 408, so that the first heatsink 412, the second heatsink 414, or both attain the predetermined thermal energy capacity at substantially a same time.

Because of the structural versatility of the heat system 402, the first heatsink 412, the second heatsink 414, or both may be positioned in a front, a back, a side, a top, or a bottom of an image capture device, such as the image capture devices 100, 200 of FIGS. 1A-2B. The first heatsink 412 and the second heatsink 414 may be located on opposite sides or opposite regions of the image capture device. For example, the first heatsink 412 may extend along a front side, and the second heatsink 414 may extend along a rear side of the image capture device.

For controlling conduction in the heat system 402, the heatsinks 412, 414 connect by the conductors 418, 420 that facilitate the movement or management of thermal energy from the PCB 406, the component 408, or any other component(s). For facilitating thermal energy, the first heatsink 412, the second heatsink 414, or both may be made of or include aluminum, aluminum alloys, copper, or copper alloys. When connecting, the conductors 418, 420 may be a single contiguous conductor that connects multiple components together or may be physically separate pieces such that the conductors 418, 420 are spaced a distance a part. The conductors 418, 420 may be composed of a material suitable to manage or move thermal energy such as graphite, graphene, metals, aluminum, silver, copper, polyimide, silicone-coated fabrics, gap fillers, epoxy, thermal grease, or any combination thereof.

For circumventing the PCB 406, the component 408, or both, the conductor 418 provides a connection that is thermal, mechanical, or both between the first heatsink 412 and the PCB 406 to assist with conduction or convection in the heat system 402. For connecting the first heatsink 412 and the PCB 406, straight portions 424a, 424b, 424c extend along sides of the PCB 406, the component 408, and the first heatsink 412 and curve at bent portions 426a, 426b so that thermal energy can be moved from the PCB 406 to the first heatsink 412. Alternatively, any of the straight portions 424a, 424b, 424c may extend adjacent to, in contact with, around with a space between, or proximate to the first heatsink 412, the PCB 406, or both.

FIG. 5A is a side view of a heat system 502 similar to the heat system 402 of FIG. 4. The heat system 502 encloses or partially encloses a lens 504, a PCB 506, a component 508, and another component 510 configured to provide thermal energy. The heat system 502 includes a first heatsink 512 and a second heatsink 514 that may be similar to the heatsinks 412, 414 in the heat system 402 of FIG. 4. The details of the components are discussed below.

For supporting the component 508 in the heat system 502, the second heatsink 514 includes flanges 516 positioned above a top side and flanges 517 positioned below a bottom side of the component 508 so that the component 508 is housed in a basket or slot structure. The flanges 516, 517 may connect to a structure that houses the component 508 so that thermal energy provided by the component 508 is moved by conduction through the structure to the heatsink 514. For separating the heatsinks 512, 514, the component 508 is positioned between the heatsinks 512, 514 so that thermal energy may be dissipated over a larger volumetric space relative to a single heatsink, such as only the second heatsink 514. The larger volumetric space may allow thermal energy to be dissipated by convection or conduction or, alternatively, may allow for more thermal energy to be distributed between the first heatsink 512 and the second heatsink 514 so that activity time of an image capture device including the heatsinks 512, 514 may be extended compared with a system where the thermal energy is not balanced. The flanges 516, 517 may provide more volumetric space to distribute thermal energy in the heat system 502 by increasing the overall mass of the second heatsink 514.

Around the component 508 and the PCB 506, the heatsinks 512, 514 are connected by multiple conductors 518, 520 that circumvent the backside of the component 508 and the PCB 506 so that the component 508 is able to be disconnected at a side portion or location of the heat system 502 while thermal energy distribution is at the same time increased. The conductors 518, 520 may extend along any side of the component 508 or the PCB 506, such as a back, a bottom, a top, a front, or any other side, to circumvent the component 508 and connect to either of the heatsinks 512, 514. The conductors 518, 520 may be similar to the conductors 418, 420 of FIG. 4. The heatsinks 512, 514 distribute thermal energy in the heat system 502 so that an amount of thermal energy located on opposing sides of the system may be balanced to extend activity time. Activity time may mean that the image capture device is capturing images as described by any technique described herein and, for example, may be between about 20 minutes and about 80 minutes, about 30 minutes and about 70 minutes, or about 40 minutes and about 60 minutes.

FIG. 5B is an opposite side view of the heat system 502 of FIG. 5A, with the component 508 removed for clarity. The lens 504 connects with the component 510 that is configured to provide thermal energy to the heat system 502. For example, the component 510 may heat up during operation such that introducing thermal energy into the heat system 502 and the first heatsink 512, the second heatsink 514, or both may move or manage the thermal energy introduced into the heat system 502. The component 510 may be similar to the component 408 or any component associated with the PCB 406 of FIG. 4. Another conductor 522 connects the component 510 and the first heatsink 512 to help facilitate movement or management of thermal energy from the component 510. The conductor 522 is serpentine shaped so that the conductor 522 is capable of circumventing other components in an image capture device, such as the image capture devices 100, 200 of FIGS. 1A-2B.

As shown in FIG. 5B, the first heatsink 512 and the PCB 506 are connected by a straight portion 524b that extends in a diagonal manner or shape so that the conductor 518 contacts the densest portion of volumetric area on the first heatsink 512, the PCB 506, or both. Alternatively, while connected to the first heatsink 512 and the PCB 506, another straight portion (not shown in FIG. 5B) of the conductor 518 may extend along or contact sides of the component 510 so that thermal energy from the component 510 may be dissipated through convection, conduction, or both based on having a location adjacent to or in contact with the component 510. The contact position of the conductor 518 to the PCB 506, component 510, or both may have the densest volumetric area where thermal energy is provided in higher abundance relative to other portions on the PCB 506 or component 510 that provide thermal energy. Furthermore, the conductor 518 may contact the first heatsink 512 at a location having a densest volumetric area or on a portion of the first heatsink 512 that is furthest from other components that provide thermal energy.

The conductor 518 and the first heatsink 512 contact at a conductor box 530. The conductor box 530 is laterally offset with the point of contact of the PCB 506 and the conductor 518 relative to the first heatsink 512 so that the point of contact with the first heatsink 512 is above the point of contact with PCB 506. The conductor 522 contacts the first heatsink 512 at another conductor box 531 that may be similar to the conductor box 530. The conductor boxes 530,531 press the conductors 518, 522 against the first heatsink 512 to create a mechanical connection, thermal connection, or both between the conductors 518, 522 and the first heatsink 512. The conductor boxes 530, 531 may be composed of foam or similar compressible material so that other components may assist in pressing the conductor boxes 530, 531 against the conductors 518, 522 and the heatsink 512.

FIG. 6A is a perspective view of a heat system 602 similar to the heat system 502 of FIGS. 5A-5B. FIG. 6B is a different perspective view of the heat system 602 of FIG. 6A. The heat system 602 includes a PCB 606, a component 607 configured to provide thermal energy, a first heatsink 612, and a second heatsink 614. The component 607 is disposed on the PCB 606, and the PCB 606 may be similar to the PCB 406 in FIG. 4 or the PCB 506 in FIGS. 5A-5B. The component 607 may be present and not shown in other iterations of a heat system, such as the heat systems 402, 502 illustrated in FIGS. 4-5B. In some examples, the PCB 606, the component 607, or both may provide thermal energy throughout the heat system 602.

In a similar manner to the heatsinks 412, 414, 512, 514 and the conductors 418, 420, 518, 520 of FIGS. 4-5B, the heatsinks 612, 614 move thermal energy provided by the component 607 through conductors 618, 620 to dissipate thermal energy by conduction or convection through the heat system 602. A portion or multiple portions of the component 607 may be covered by a portion of the conductor 618, the conductor 620, or both, so that the component 607 may be coupled to the first heatsink 612, the second heatsink 614, or both. The conductors 618, 620 may be directly connected to the component 607, the heatsinks 612, 614, or any combination thereof through a thermal paste that conducts thermal energy that passes through the conductors 618, 620, the heatsinks 612, 614, the component 607, or any combination thereof. For stronger connections to the conductors 618, 620, the thermal paste may be a thermal adhesive, tape, or grease that provides a mechanical connection or structural bond between the conductors 618, 620 and the heatsinks 612, 614. Examples of thermal paste include an epoxy blend, a cyanoacrylate blend, and/or a composition containing metals, graphite, or graphene so that thermal conduction or facilitation is improved.

To free the conductors 618, 620 from contact with the PCB 606, the conductors 618, 620 include raised portions 623a, 623b that directly contact each other and the component 607 and raise the conductors 618, 620 from a surface(s) of the PCB 606. In some examples, the raised portions 623a, 623b are free of contact with each other. The raised portion 623a associated with the conductor 618 contacts the straight portions 624a, 624b, 624c that connect the conductor 618 and the PCB 606, and the raised portion 623b of the conductor 620 connects with the straight portions 624d, 624e that connect the conductor 620 and the second heatsink 614. Having a clip-like shape and structure, the conductor 620 contacts the component 607 on a side of the PCB 606, and the conductor 620 contacts a side of the second heatsink 614 that faces away from the PCB 606 so that that the conductor 620 moves over an edge of the PCB 606 and an edge of the second heatsink 614 at a curved portion 628 of the conductor 620. Like the conductor boxes 530, 531 of FIGS. 5A-B, a conductor box 630 provides a direct connection for the straight portion 624c of the conductor 618 and the first heatsink 612. Thus, a contiguous connection among the heatsinks 612, 614 and the component 607 is made so that the conductors 618, 620 are free of direct contact with the PCB 606.

FIG. 7A is a perspective view of a heat system 702 used in an image capture device, such as the image capture devices 100, 200 of FIGS. 1A-2B. The heat system 702 includes a lens 704, a circuit 706, a component 710, a heatsink 712, a conductor 722, and a conductor box 730. The circuit 706 may be similar to the PCB 406 of FIG. 4 or the PCB 606 of FIGS. 6A-6B. The component 710 may be similar to the component 408 of FIG. 4 or the component 510 of FIGS. 5A-5B. The heatsink 712 may be similar to the first heatsink 412 of FIG. 4. The conductor 722 may be similar to the conductors 418, 420 of FIG. 4 or the conductor 522 of FIGS. 5A-5B. The conductor box 730 may be similar to the conductor boxes 530, 531 of FIGS. 5A-5B. Details of the heat system 702 are discussed herein.

Structurally, the heatsink 712 includes a base 734, cutouts 736, 737, and a recess 742 so that a portion of the circuit 706 is stored in a position within the recess 742 that is separated from the component 710. The heatsink includes a front surface 743 and an opposing rear surface (not shown) so that the circuit 706 contacts the front surface 743 at the base 734, routes through the cutout 737, and contacts the rear surface at the recess 742. One cutout 736 is defined in the base 734 and contacts a portion of the circuit 706, and the other cutout 737 contacts the recess 742, the base 734, and another portion of the circuit 706.

For additional housing configurations of the circuit 706 or other components, the recess 742 has a staggered structure that includes a shallow portion 744 and a deep portion 746. The shallow portion 744 and the deep portion 746 are spaced a distance away from the component 710 so that the recess 742 is free of contact with the component 710. However, the deep portion 746 contacts the conductor box 730, which, along with the conductor 722, facilitates the movement or management of thermal energy between the heatsink 712 and the component 710.

For mitigating electromagnetic signals that are provided or emitted by the component 710, the heatsink 712 divides or separates the component 710 and a portion of the circuit 706 so that part of the heatsink 712 is positioned between the portion of the circuit 706 and the component 710. Further, the blocking or mitigating of electromagnetic signals by the heatsink 712 from the component 710 prevents the circuit 706 from acting as an antenna for amplifying electromagnetic signals and, thus, interfering with other components or functionalities in the image camera device, such as WiFi reception or GPS signaling. The component 710 is proximate to, contacting, adjacent to, or spaced apart from the front surface 743 at the recess 742 so that the heatsink 712 separates the portion of the circuit 706 that is proximate to the rear surface at the recess 742 and the component 710 that is proximate to the front surface 743 at the recess 742. In some examples, the recess 742, the base 734, or portions of both may be positioned directly or indirectly between the component 710 and the portion of the circuit 706 or any other component.

Additionally, the heatsink 712 may include an LCD screen (not shown), a display, or a similar component that is adjacent to the circuit 706, the rear surface of the heatsink 712, or both. For mitigating amplification of electromagnetic signals from the component 710, the heatsink 712 separates or divides the LCD screen and the circuit 706 from the component 710 by being a physical wall. However, in some examples, the heatsink 712 may divide or separate the component 710, the LCD screen, the circuit 706, or a combination thereof so that alternative combinations are possible. In addition, the heatsink 712 may be a physical wall between the component 710 and the circuit 706, and the heatsink 712may blocks or mitigates electromagnetic signals from interfering with or damaging other components that are adjacent to or in contact with the heatsink 712 or the LCD screen. Further, in examples where the circuit 706 provides thermal energy, the base 734 and the recess 742 efficiently house the circuit 706 and can be configured to distribute or dissipate thermal energy from the component 710, the circuit 706, or both. Finally, the base 734 and the recess 742 provide a staggered structure that permits housing combinations of components, like the circuit 706 and the LCD screen, and allows for blocking or mitigation of unintended inter-component interactions near the heatsink 712. In other words, the heatsink 712 is serving as a structural separation between components in order to provide interference from electromagnetic signals that come into contact with the circuit 706.

FIG. 7B is a front view of the heatsink 712 of FIG. 7A. For connecting components that are adjacent to the opposing rear surface (not shown) and the front surface 743 of the heatsink 712, the circuit 706 contacts the rear surface at the recess 742, extends through the cutout 737, and contacts the front surface 743 at the base 734. As the circuit 706 continues to extend along the front surface 743, the circuit 706 contacts the cutout 736 and folds back approximately 180 degrees towards the recess 742 so that a portion of the circuit 706 is folded over and contacting another portion of the circuit 706. An edge of the cutout 736 is free of contact with an edge of the circuit 706 so that a gap is defined between the cutout 736 and the circuit 706 and additional circuitry (not shown) can be routed from or through the rear surface, the gap, and the front surface 743 to connect with other components in the image capture device.

FIGS. 8A-8C illustrate the specific structural intricacies and advantages of another example of a heatsink 812. FIG. 8A is a front perspective view of the heatsink 812. The heatsink 812 may be similar to the heatsink 712 of FIGS. 7A-7B. The heatsink 812 may also be similar to the first heatsink 412 of FIG. 4 or the heatsink 712 of FIGS. 7A-7B. The heatsink 812 includes a base 834, cutouts 836, 837, apertures 838, and a recess 842. The base 834 is in a first generally horizontal plane, and the recess 842 is in a second generally horizontal plane so that the first plane and the second plane are laterally offset by a perpendicular distance. The recess 842 has a staggered structure that includes a shallow portion 844 and a deep portion 846 laterally offset from each other so that additional configurations of components may be housed within the recess 842. Generally horizontal surfaces of the shallow portion 844 and the deep portion 846 are spaced from the surface of the base 834 in a perpendicular direction, and the deep portion 846 is spaced further from a surface of the base 834 than the shallow portion 844. The staggered structure of the shallow portion 844 and the deep portion 846 of the recess 842 provides multiple surfaces for connecting conductors, such as conductor 522 of FIG. 5, that help to move thermal energy of the components for improved thermal energy balance or distribution within a heat system.

For providing a pass-through in the heatsink 812 to any component, the cutout 836 is defined in the base 834, and the other cutout 837 is in defined in both the base 834 and the recess 842 so that one edge of the cutout 837 contacts the base 834 and another edge of the cutout 837 contacts the recess 842. The cutouts 836, 837 provide a pathway for a circuit, such as the circuit 706 of FIGS. 7A-7B, to contact the heatsink 812 on a front surface 847 and an opposing rear surface 848 so that a portion of the circuit contacts the front surface 847 and another portion contacts the rear surface 848. In some examples, components, like an LCD screen or the component 710 of FIGS. 7A-7B, may contact either the front surface 847 or the rear surface 848.

FIG. 8B is a rear perspective view of the heatsink 812 of FIG. 8A. The base 834 includes a cutout 849 that may house any connection or component used in an image capture device or heat system, such as the image capture devices 100, 200 of FIGS. 1A-2B or the heat systems 402, 502 of FIGS. 4-5B. The base 834 includes a depression 850 that is laterally offset from a surface of the base 834 in a perpendicular direction away from a surface of the recess 842 to allow for housing additional component(s). For routing electrical connections within a heat system, the depression 850 allows for a circuit (not shown, e.g., the circuit 706 of FIGS. 7A-7B) to be inserted within the depression 850 and routed through the cutout 836, the cutout 837, or both. The circuit can then be connected one or more components, such as an LCD, in an image capture device.

FIG. 8C is a side view of the heatsink 812 of FIGS. 8A-8B. An X-axis and a Y-axis of the heatsink 812 are indicated to show the staggered structure of the recess 842 and the base 834. The recess 842 is raised in a direction along the Y-axis above the base 834, and the shallow portion 844 and the deep portion 846 are staggered along the Y-axis above the base 834. A surface of the base 834 runs an entire width of the heatsink 812 along the X-axis and covers multiple sides of the recess 842 to form a cup-like structure that is capable of housing any component described herewith. The additional space provided by the recess 842 allows any component to be stored at the rear surface 848 of the heatsink 812 so that the heatsink 812 can physically separate or divide varying components in an image capture device. Additionally, the composition of the heatsink 812 or the physical obstruction from the presence of the heatsink 812 may provide interference with electromagnetic signals or excessive thermal energy distribution so that interference among varying components is avoided or mitigated and, thus, activity time is extended, as discussed herewith.
