摘要： A cooling assembly includes an evaporator containing a primary cooling medium, a passive condenser, and a heat exchanger. When a secondary cooling medium is provided to the heat exchanger, the primary cooling medium in the gas phase switches from being received by the passive condenser to the heat exchanger without operating any valves located between the evaporator and the passive condenser and between the evaporator and the heat exchanger. The primary cooling medium circulates between the evaporator and the passive condenser and between the evaporator and the heat exchanger by natural circulation and gravity without a pump in the flow path of the primary cooling medium between the heat exchanger and the evaporator and between the passive condenser and the evaporator to circulate the primary cooling medium.

摘要： An immersion cooling system includes a work tank, a pump, a first pipeline, a condensation dehumidification device, a second pipeline, and a control system. The work tank includes a vapor section and a humidity sensor for sensing a humidity of the vapor section. The first pipeline includes a first valve. The vapor section and the pump are selectively in communication with each other or not when the first valve is actuated. The condensation dehumidification device has a first end and a second end, where the first end is in communication with the pump. The second pipeline includes a second valve. The condensation dehumidification device and the tank are selectively in communication with each other or not when the second valve is actuated. When the humidity is greater than a preset humidity, the control system controls the first valve to communicate the vapor section and the pump and activates the pump.

摘要： The present invention provides devices and methods for the cryogenic storage of biological material. Devices of the invention are useful for storing material at a predetermined cryogenic temperature. An intermediate storage chamber (ITC) set within an adiabatic Dewar container includes a set, or multiple, heat transfer pipes that passively act to maintain a set temperature or temperature range. Some embodiments utilize an inner heat pipe to transfer heat out to a heat sink and an outer heat pipe to transfer heat into the ITC from a cool sink. The heat pipes may be arranged, designed, and/or tilled to conduct heat energy only when set parameters beyond the predetermined range are experienced within the ITC. The method of maintaining a predetermined temperature range by means of a heat sink and cool sink are taught herein.

摘要： Photonic and electronic integrated circuits can be cooled using variable conductance heat pipes containing a non-condensable gas in addition to a phase-changing working fluid. To package the heat pipe with a subassembly including the integrated circuits in a standard housing providing a heat sink contact area, the heat pipe is oriented, in some embodiments, with its axis between evaporator and condenser ends substantially perpendicular to the direction along which the integrated circuit subassembly is separated from the heat sink contact area, and a portion of the exterior surface of the heat pipe is thermally insulated, with a suitable thermal insulation structure, from the heat sink contact area.

摘要： A temperature sensor for a first fluid senses a temperature of the first fluid downstream of a heat exchanger. A supply for a second fluid changes a temperature of the first fluid. The supply for the second fluid passes through the heat exchanger. A valve is positioned upstream of the said heat exchanger on the supply for the second fluid, and controls a flow rate of the second fluid diverted into a bypass line compared to a flow rate of the second fluid directed through the heat exchanger, with the three-way valve controlled by a control in response to feedback from said temperature sensor. The valve changes the respective flow rates delivered into the bypass line and through the said heat exchanger in a non-linear manner with a change in valve position. A manned spaceship is also disclosed.

摘要： A basic structural body for constructing heat dissipation device and a heat dissipation device are disclosed. The heat dissipation device includes a first basic structural body having a wick structure formed on one side surface thereof; and the first basic structural body and the wick structure are structural bodies formed layer by layer. Two pieces of first basic structural bodies can be correspondingly closed together to construct a heat dissipation device internally defining an airtight chamber. In this manner, the heat dissipation device can be designed in a more flexible manner.

摘要： A method for cooling a hybrid electric aircraft propulsion system comprises transporting a coolant through a two-phase pumped loop (TPPL) in thermal contact with an electrical machine and a plurality of power modules to be cooled, where the TPPL includes: a parallel arrangement of cold plates; an evaporator; a condenser; a first control valve; a liquid receiver; and a pump. A sensor positioned upstream of the cold plates, and in some cases upstream of the liquid receiver, measures pressure and/or temperature of a return stream of the coolant and transmits measurement data to a first controller electrically connected to the first control valve. The first controller regulates flow of a first liquid stream through the first control valve based on the pressure and/or temperature measured by the sensor, thereby keeping the return stream at a temperature within a predetermined temperature range.

摘要： A refrigeration and/or heat transfer device includes a heating section and cooling section, a release member, and a one-way check valve affixed together in a continuous loop so working fluid may flow in one direction therein. The heating section absorbs heat and transfers such heat to the working fluid, thereby heating, expanding and increasing pressure upon the working fluid therein. The pressurized working fluid is released in a regulated manner from the heating section to the cooling section, thereby carrying the heat away. The released working fluid cools and transfers its heat to the surroundings within the cooling section. As released working fluid enters the cooling section, such fluid displaces already cooled working fluid, pushing such fluid through the one-way check valve back into the heating section to absorb heat. The working fluid may undergo a phase change or remain in a single phase throughout to enhance heat transfer.

摘要： A heat pipe heat exchanger is used in combination with a damper assembly to selectively control an amount of heat exchange provided. A divider defines discrete heat pipe plenums and bypass plenums within a duct, and the heat pipe system is configured so that all of the coils of one portion of the heat pipe system are received in the heat pipe plenum(s), while the bypass plenum(s) are free of any coils. The damper assembly includes adjustable heat pipe dampers aligned with the heat pipe plenums and adjustable bypass dampers aligned with the bypass plenums. The damper assembly can include a single actuator that simultaneously opens the heat pipe dampers and closes the bypass dampers and simultaneously closes the heat pipe dampers and opens the bypass dampers.
