  • Patent number: 9049801
    Abstract: A thin portable electronic device with a display is described. The components of the electronic device can be arranged in stacked layers within an external housing where each of the stacked layers is located at a different height relative to the thickness of the device. One of the stacked layers can be internal metal frame. The internal metal frame can be configured to act as a heat spreader for heat generating components located in layers adjacent to the internal frame. Further, the internal metal frame can be configured to add to the overall structural stiffness of the device. In addition, the internal metal frame can be configured to provide attachment points for device components, such as the display, so that the device components can be coupled to the external housing via the internal metal frame.

    Abstract: A heat pump includes a SAS structure with a wall defining a first open side and a second open side. The heat pump also includes an interconnect board, enclosed within the SAS structure including openings. Thermoelectric modules are mounted on the interconnect board at the locations defined by the openings. The heat pump additionally includes a hot-side heat spreader that is in thermal contact with the first side of each thermoelectric module and a cold-side heat spreader that is in thermal contact with the second side of each thermoelectric module. The periphery of the hot-side heat spreader mechanically contacts the wall of the SAS structure at the first open side, and the periphery of the cold-side heat spreader mechanically contacts the wall of the SAS structure at the second open side such that any compression force applied to the heat pump is absorbed by the SAS structure.

  • Patent number: 9008993
    Abstract: According to one aspect, a portable electronic device having a heat generating component, a thermal sensor, an energy storage device for powering the portable electronic device, a thermal element thermally coupled to the heat generating component, the energy storage device, and the thermal sensor. The thermal element is sized and shaped so that heat generated by the heat generating component flows through the thermal element towards the thermal sensor and interacts with the energy storage device. The thermal sensor is used to monitor a thermal profile for the thermal element, and the monitored thermal profile is compared with an expected thermal profile to determine if the integrity of the portable electronic device has been compromised.

  • Patent number: 8934248
    Abstract: A thermal dissipator includes an elongated laminar thermal transfer member having opposite sides, opposite ends and a longitudinal axis extending between those ends. The member has a thermal conductivity along its axis and in a first plane extending between its sides that is substantially greater than the thermal conductivity of the member in a second plane transverse to the first plane. A transverse heat sink structure contacts at least one side of the thermal transfer member along the length thereof, and extends from the thermal transfer member in a direction parallel to the first plane. A compression device compresses the thermal transfer member and the heat sink structure together to establish intimate thermal contact therebetween. Solid state lighting apparatus incorporating the dissipator is also disclosed.
