A heat transfer apparatus includes a first chamber horizontally offset from a second chamber to form an upper housing and a lower housing. The upper housing may be stacked on top of and fastened to the lower housing. The heat transfer apparatus may include a heat exchange interface fixed to a bottom surface of the lower housing. The heat exchange interface may absorb heat from a proximate heat source and transfer the absorbed heat to an inner surface of the lower housing. The apparatus includes a pump including an impeller and a stator disposed therein. The lower housing may separate the impeller from the stator so that the stator is isolated from the impeller by a surrounding casing. A liquid coolant may be circulated from an inlet, over the heat exchange interface and out to an outlet to remove heat from a processer proximate to the heat exchange interface.

A heat rejection system that employs temperature sensitive shape memory materials to control the heat rejection capacity of a vehicle to maintain a safe vehicle temperature. The technology provides for a wide range of heat rejection rates by actuation of the orientation or position of a heat rejection panel which impacts effective properties of the heat rejection system in response to temperature. When employed as a radiator for crewed spacecraft thermal control this permits the use of higher freezing point, non-toxic thermal working fluids in single-loop thermal control systems for crewed vehicles in space and other extraterrestrial environments.

A method and corresponding system for extracting an unsuitable and/or unknown and/or contaminated coolant gas from an air conditioning system. An existing coolant fluid recovery/charging machine is used in order to extract the heat required to cool said containment element of the coolant to be extracted or extracted.

A condensing heat exchanger to exchange heat from a hot flow to a cold flow includes a hot flow side to receive the hot flow, the hot flow side including a hot flow inlet disposed on a hot flow inlet side and a hot flow outlet disposed on a hot flow outlet side, wherein a hot flow side cross section decreases from the hot flow inlet side to the hot flow outlet side, a cold flow side to receive the cold flow, and an interface disposed between the hot flow side and the cold flow side to allow thermal communication therebetween.

A cooling apparatus includes a cold plate including a lower surface to be in contact with a heat-radiating component, and a first coolant passage in which a coolant flows, a radiator including fins to perform cooling and pipes each defining a second coolant passage in communication with the first coolant passage, a pump to circulate the coolant, a first tank joined to one end of each of the pipes, and a second tank to join another end of each of the pipes to the pump. The radiator is provided on the cold plate, and the pump is adjacent to the second tank.

The disclosure provides a fluid-cooled heat sink having a heat transfer base, a shroud, and a plurality of heat transfer fins in thermal communication with the heat transfer base and the shroud, where the heat transfer base, heat transfer fins, and the shroud form a central fluid channel through which a forced or free cooling fluid may flow. The heat transfer pins are arranged around the central fluid channel with a flow space provided between adjacent pins, allowing for some portion of the central fluid channel flow to divert through the flow space. The arrangement reduces the pressure drop of the flow through the fins, optimizes average heat transfer coefficients, reduces contact and fin-pin resistances, and reduces the physical footprint of the heat sink in an operating environment.

A radiator includes a base, a tubular structure, a plurality of fins and a spiral structure. The base has a water input port and a water output port. The tubular structure is coupled to the base and is further connected with the water input port and the water output port. A spiral structure is arranged inside the tubular structure, or the inner surface of the tubular structure has a delay structure formed by a plurality of bumps for improving heat dissipation efficiency of water. The tubular structure runs through the plurality of fins. In addition, the radiator of the present invention is applied to a hydrogen generator. The base of the radiator is directly and integrally formed with the upper cover of the water tank of the hydrogen generator, and the assembly can be completed only by coupling the base to the tube, thereby reducing the assembly process.

A battery pack prevents an inflow of a leaking coolant. The battery pack includes a housing, in which at least one battery cell or battery module is mounted, a heat exchanger provided in the housing for cooling the battery cell or the battery module, and seal provided between the heat exchanger and the inner surface of the housing for preventing coolant leaking from the heat exchanger from flowing into a space in which the battery cell or the battery module is placed, whereby the stability and reliability of the battery pack are improved.

A vapor chamber structure includes a main body having multiple internal independent chambers. A capillary structure is disposed in each of the independent chambers. A working fluid is contained in each of the independent chambers. The working fluids contained in the independent chambers have different physical or chemical properties. The independent chambers are respectively in contact with different heat sources with different properties to conduct the heat. Accordingly, one single vapor chamber structure can provide complex heat conduction effect for different heat sources.

A liquid cooling structure may include a lower structure and an upper structure. The lower structure may be configured to cover one surface of an object. The upper structure may be combined with the lower structure to provide a channel through which a cooling fluid may flow. The channel may include a plurality of passages connected between a channel inlet through which the cooling fluid may enter and a channel outlet through which the cooling fluid may exits.
