A heat exchange assembly comprising: (I) two or more panels; (II) a plurality of channels formed between the two or more panels; and (III) one or more reservoirs located adjacent to the plurality of channels and configured to at least temporarily store a temperature control material, wherein the plurality of channels are configured to direct a flow path of the temperature control material between the two or more panels and provide structural rigidity to the assembly.

A heat transfer surface for use in conjunction with a heat exchanger is disclosed. The heat transfer surface a corrugated member where rows of corrugations that are offset relative to each other forming at least an alternating series of first and second rows or first, second and third rows. In some embodiments the heat transfer surface includes a heat transfer enhancement feature disposed within individual corrugations of the corrugated member to provide a more turbulent or tortuous fluid flow path through the heat transfer surface. In some example embodiments the heat transfer enhancement feature is a ridge disposed in the planar portions of at least some of the rows of corrugations. In other example embodiments the planar fin portions are porous fin surfaces. In other embodiments, the corrugated member cooperates with heat transfer enhancement features in the form of triangular protuberances disposed on their inner surfaces of spaced apart plates.

The invention relates to a brazable three-layered aluminum composite material having at least three layers with at least two different aluminum alloys, whereby an inner layer of the at least three layers is an aluminum brazing layer made from an aluminum brazing alloy, the other layers are configured as covering layers and include at least one further aluminum alloy, wherein the at least one further aluminum alloy has a higher solidus temperature than the liquidus temperature of the aluminum brazing alloy. The individual covering layers have a thickness which exceeds the thickness of the aluminum brazing layer by at least a factor of 1.5, preferably by a factor of 5. The brazable aluminum composite material is simply structured, has good brazing properties for the production of butt-joint brazing connections, significantly reduces the risk of a ‘burning through’ of brazed-on components and provides sufficient mechanical properties.

A cooler includes a cooling pipe having a cooling surface in contact with a heat-exchanged component, and a refrigerant passage. A pair of outer passages are formed between a pair of opposed inner wall surfaces which are located at both ends of an inner wall surface of the cooling pipe in a perpendicular direction and which constitute the refrigerant passage, and a pair of partition walls that are located at both ends of an inner fin in the perpendicular direction. At least one flow-regulating rib is formed in the refrigerant passage to project into the refrigerant passage at a position inward of the pair of outer passages in the perpendicular direction and at a position outward of an inflow hole and a discharge hole in the perpendicular direction as well as at a position outward of the inner fin in an arrangement direction and at a position inward of the inflow hole and the discharge hole in the arrangement direction. The flow-regulating rib is configured to restrict flow rates of refrigerant through the pair of outer passages.

A gas/liquid heat exchanger for cooling a hot gas has a plastic housing at least partly surrounding a metal core. The housing has separately formed inlet and outlet segments which may be formed from plastic materials having different heat resistance, and which are joined together along a sealed joint. One or both of the inlet and outlet segments are provided with bypass blocking element to at least partially blocks any gaps between the irregularly shaped sides of the core and the sides of the housing. Where the sides of the core include indentations, the bypass blocking elements may comprise a comb structure having fingers extending into the indentations. The housing is constructed to permit the core to be slidingly received into one or both of the inlet segment and the outlet segment of the housing.

A heat exchanger comprises a stack of mutually spaced apart plates. The plates are separated by respective spacings therebetween. Alternate spacings respectively provide a flow path for a first fluid and a second fluid. The heat exchanger further comprises a first header for inflow of the first fluid and a second header for outflow of the first fluid. The first and second headers are connected to the plate stack by flexible tubular ducting means.

It is aimed to reduce the size of heat exchange tubes and also to reduce pressure loss of a fluid flowing in an external flow path formed between adjacent heat exchange tubes. A first projecting portion 41 and a second projecting portion 42 of a first heat exchange tube 2A are joined to portions around an inlet 3C and outlet 3D of a second heat exchange tube 2B. A first flow path forming portion 61, a second flow path forming portion 62, and a third flow path forming portion 63 of an internal flow path 3 of each of the first heat exchange tube 2A and the second heat exchange tube 2B face a first thin portion 21A and a second thin portion 21B of the second heat exchange tube 2B or the first heat exchange tube 2A across an external flow path 4. The first flow path forming portions 61, the second flow path forming portions 62, and the third flow path forming portions 63 of the first heat exchange tube 2A and the second heat exchange tube 2B are arranged in a staggered pattern in a width direction of the heat exchange tubes 2.

A liquid-cooling heat dissipation apparatus includes a water distribution box, a water collection box, a first radiating pipe, a second radiating pipe, a third radiating pipe, a fourth radiating pipe, and a pumping device. The channels in the liquid-cooling heat dissipation apparatus are connected in sequence to form a circuitous configuration. This allows the water to travel a longer distance in the liquid-cooling heat dissipation apparatus, so that the liquid-cooling heat dissipation apparatus can effectively cool the water and dissipate heat.

The present invention relates to a tube (1) with a reservoir of phase-change material for a heat exchange bundle (100) of a heat exchanger, said tube (1) with a reservoir of phase-change material including: two flow plates (3) which are configured to be assembled with one another in a fluid-tight fashion and form at least one duct (31) in which a first heat-transfer fluid flows between said flow plates (3), at least one reservoir plate (5) including cavities (51), said reservoir plate (5) being configured so that it can be assembled in fluid-tight fashion on an external face of one of the two flow plates (3) so as to close the cavities (51) and form housings for the phase-change material, said cavities (51) projecting from the external face of the reservoir plate (5) so that that a second heat-transfer fluid can circulate between said cavities (51).
