  • Patent number: 9300133
    Abstract: Various techniques are employed alone or in combination, to reduce the levelized cost of energy imposed by a power plant system. Solar energy concentrators in the form of inflated reflectors, focus light onto photovoltaic receivers. Multiple concentrators are grouped into a series-connected cluster that shares control circuitry and support structure. Individual concentrators are maintained at their maximum power point via balance controllers that control the flow of current that shunts this series connection. DC current from clusters is transmitted moderate distances to a centralized inverter. The inductance of transmission lines is maximized using an air-spaced twisted pair, enhancing the performance of boost-type three phase inverters. Cluster outputs are separate from individual inverters in massively interleaved arrays co-located at a central location.

  • Patent number: 8995933
    Abstract: In a communication device, a heat sink includes a solderable top surface with multiple upward facing swaging protrusions. A spacer is placed on top of the top surface of the heat sink with locating cut-outs on the spacer aligned with the swaging protrusions. A solder pre form is inserted into an opening in the spacer. The solder pre form includes locating features for alignment with the spacer and the swaging protrusions. The spacer is configured to restrict melted flow from the solder pre form to a defined area of the heat sink top surface. A printed circuit board including cut-outs and input and output connections for inserting a radio frequency device and further including locating holes for aligning the printed circuit board with the swaging protrusions is placed on top of the solder pre form and secured to the heat sink prior to a manufacturing process.

  • Patent number: 8967586
    Abstract: A supporting apparatus, configured to support a heat dissipating device, includes a bracket, two adjusting structures, and two mounting portions. Each of the two mounting portions defines a mounting hole. Each of the two adjusting structures is engaged in each of the mounting holes and includes an adjusting member and an installation member engaged with the adjusting member. Each of the adjusting members defines a through hole. The two adjusting members are rotatable relative to the two mounting portions from a first position to a second position. When the adjusting members are in the first position, a first line is running through the two through holes. When the adjusting members are in the second position, a second line is running through the two through holes, and a length of the first line is less than a length of the second line.

  • Publication number: 20150055297
    Abstract: Modules, systems, and methods are provided for cooling components of an inspection or testing apparatus, such as a borescope. In some exemplary embodiments, the modules include two heat sinks, with the top-most heat sink having a fan assembly approximately centrally disposed therein. The fan assembly can be operated to draw air into the top-most heat sink, and then exhaust airflow out of the top-most heat sink such that the exhaust air passes across at least a portion of the second heat sink to help cool both the first and second heat sinks, and components of the apparatus associated therewith, using the same fan assembly. As a result, the components of the apparatus can be cooled more easily, and the performance and efficiency of these components is improved, all while reducing the overall size and weight of the inspection apparatus.

  • Patent number: 8964388
    Abstract: An electronics enclosure has a blower and diffuser received within an enclosure. Electronic components are also received within the enclosure. The blower diffuser is positioned in contact with at least one of the electronic components. A shroud surrounds the blower diffuser and the at least one electronic component, and is spaced from an outer surface of the at least one electronic component. An opening is formed through the shroud, such that air can be driven within the shroud from the blower diffuser, and across at least one electronic component, and then outwardly of the opening. A heat exchanger is positioned in the path of air leaving the opening.

  • Patent number: 8964373
    Abstract: A system for cooling portable facilities which include heat generating electronics, interior fans, a heat sink integrally serving as part of a wall or ceiling, and an outer heat pipe assembly in thermal communication with the heat sink allowing for heat dissipation. External fans pull external air over the outer heat pipe assembly. A first transducer monitors inner air temperature within the portable building, a second transducer monitors the outer heat pipe assembly, and a third transducer is secured proximate to a fin side of the heat sink. A controller is connected to the transducers, fans, and power supply. Computer instructions monitor temperatures from the transducers, compare the temperatures to preset limits, and individually or simultaneously actuate, regulate, or turn off the fans when monitored temperatures meet or exceed preset limits.
