  • Patent number: 10295270
    Abstract: A heat pipe includes one or more reservoirs of liquid that are closed at lower temperatures and open at higher temperatures. The opening of the reservoirs at higher temperatures caused by higher power levels dynamically increases the amount of liquid in the heat pipe, which increases performance of the heat pipe at higher power levels. As the heat pipe cools, the liquid condenses and flows back into the reservoirs. As the heat pipe continues to cool, the reservoirs close. The result is a heat pipe that is more efficient at lower power levels and still maintains high efficiency at higher power levels due to the demand-based charging of the liquid based on temperature.

  • Patent number: 10247489
    Abstract: A heat sink structure is provided having fins mechanically altered dynamically to change and optimize the heat sink's performance based on certain environmental conditions. Specifically, the shape of fins of the heat sink structure is dynamically altered in response to environmental conditions that indicate the need for increased thermal performance by spreading the fins through a mechanical device dynamically, or by collapsing the fins to reduce pressure drop across a region when increased thermal performance is not needed.

  • Patent number: 10215501
    Abstract: A thermally actuated heat pipe control valve which includes a housing having a first opening for receiving a condenser portion of a heat pipe therein, a second opening for receiving an evaporator portion of the heat pipe therein and a passage extending through the housing from the first opening to the second opening. The passage is configured to receive working fluid from the heat pipe therein. A passage closing member is positioned in the housing proximate to or in the passage. The passage closing member having a surface which cooperates with a wall of the passage. At a specific temperature, the passage closing member moves into the passage to a closed position, preventing the flow of the working fluid, thereby preventing heat transfer between the condenser portion and the evaporator portion when the design temperature is reached or exceeded.

  • Patent number: 10211125
    Abstract: Various embodiments of the disclosure are directed to vapor chambers with a structure that permits configurable mounting holes. Such vapor chambers may have a top plate with apertures and a bottom plate with apertures. Spacers are inserted into the apertures and disposed between the top plate and the bottom plate. Each spacer may have their own aperture that extends throughout the spacer which acts as the mounting hole in the assembled vapor chamber. The various dimensions of the spacers can be configured and selected in order to accommodate varying dimensions of the apertures in the top plate and the bottom plate. These spacers can be used to provide mounting holes of a desired size and provide additional structure support to the vapor chamber. The spacers also lie flush with the top and bottom plates which increases the surface area of the vapor chamber and improves the mounting of the vapor chamber to other structures.

  • Patent number: 10200187
    Abstract: In an optical communications system, the thermal pathway for dissipating heat generated by clock and data recovery (CDR) circuitry of an optical communications module is a separate from the thermal pathway that is used to dissipate heat generated by other components of the module. The CDR circuitry is external to the module and is provided with its own heat dissipation device. Keeping the CDR circuitry external to the module and providing it with its own heat dissipation device decouples the thermal pathway for dissipating heat generated by the CDR circuitry from the thermal pathways used for dissipating heat generated by other components of the module. This results in more effective heat dissipation and better component performance.
