An expansion assembly for use with a heat exchanger includes a block thermal expansion valve; and a distributor directly connected to the block thermal expansion valve; wherein the distributor comprises a tube having a plurality of openings formed therein.

A metal-on-ceramic substrate comprises a ceramic layer, a first metal layer, and a bonding layer joining the ceramic layer to the first metal layer. The bonding layer includes thermoplastic polyimide adhesive that contains thermally conductive particles. This permits the substrate to withstand most common die attach operations, reduces residual stress in the substrate, and simplifies manufacturing processes.

A dissipating device configured to dissipate the heat energy generated by the heat sources in the electronic devices. When the dissipating device contacts the heat sources, the heat energy can be absorbed by the dissipating device. The working fluid is stored within the dissipating device such that the working fluid can undergo a phase transition after the dissipating device absorbs heat energy. Then the working fluid can circulate inside the dissipating device. Accordingly, the heat-dissipation mechanism, which is applied to the dissipating device contacting the electronic devices, can be effectively sped up. The dissipating device is formed into a thin structure to achieve an excellent heat-dissipation effect with a limited heat-dissipation area.

A coldplate assembly includes a plurality of leak-tight conduit modules provided between a base and a cover to couple a first manifold cavity to a second manifold cavity. Each leak-tight conduit module includes a heat conducting structure and is pre-constructed and pre-tested prior to integration into the coldplate assembly. Each leak-tight conduit module is sealed only near the ends of the module that are disposed in the respective manifold cavity.

Provided is a heat exchanger capable of being efficiently and easily produced. The present invention is directed to a heat exchanger having an outer packaging body 1 having an inlet 16, an outlet 16, a pair of opposing walls, and a corrugated inner fin 2 disposed between the pair of opposing walls and provided alternately and continuously with a concave portion 25 and a convex portion 26. The outer packaging body 1 is formed of an outer packaging laminate material L1 in which a resin heat-fusible layer 52 is provided on an inner surface side of a metal heat transfer layer 51. The inner fin 2 is formed of an inner core laminate material L2 in which a heat-fusible layer 62 is provided on both surface sides of a metal heat transfer layer 61. The inner fin 2 is formed in a rectangular wave shape in which a concave portion and a convex portion are alternately and continuously provided, a concave bottom wall of the inner fin and a convex top wall of the inner fin are arranged parallel to the pair of opposing walls, and a rising wall connecting the concave bottom wall and the convex top wall is arranged perpendicular to the pair of opposing walls.

A heat exchanger for an internal combustion engine may include a base tube and a flange extending at least partially around the base tube. The flange may be formed as a forged piece.

A heat and humidity exchanger comprises panels made up of membrane sheets attached on either side of a separator. Channels extend across each panel between the separator and the membrane sheets. The panels are much stiffer than the membrane sheets. Panels are stacked in a spaced apart relationship to provide an ERV core. Spacing between adjacent panels may be smaller than a thickness of the panels,

A cooling array for cooling of an electronic component includes the electronic component, a housing which at least partially enclosing the electronic component, a heat sink support connected to the housing in a fluid-tight manner, and a heat sink which is accommodated in the heat sink support. The heat sink is thermally coupled to the electronic component in order to disperse heat generated by the electronic component.

A total heat exchange element includes a plurality of partition members made of a material that contains cellulose as a main component, a spacing member made of a material that contains cellulose as a main component, and an adhesive portion bonding the partition members and the spacing member together. The partition members are configured as flat sheets, and are stacked with a predetermined distance between them. The spacing member is disposed between adjacent ones of the stacked partition members to maintain the distance between them. The total heat exchange element has a first air flow path and a second air flow path alternately formed with one of the partition members interposed between the first and second air flow paths. The adhesive portion contains, as an adhesive component, cellulose having a smaller diameter than both of the cellulose forming the partition members and the cellulose forming the spacing member.
