A heat exchanger has: an inlet manifold having an inlet port; and an outlet manifold having an outlet port. A first gas flowpath passes from the inlet port to the outlet port. A plurality of plate banks are positioned end-to-end, each plate bank having a plurality of conduits with interiors along respective branches of the first gas flowpath, a second gas flowpath extending across exteriors of the plurality of conduits. One or more docks couple adjacent ends of the plurality of plate banks.

A heat exchanger includes heat exchanger plates in a stacked arrangement such that each heat exchanger plate is spaced apart from the adjacent heat exchanger plate. The space between adjacent heat exchanger plates defines an external fluid passageway, and each external fluid passageway is configured to receive a first fluid. Each heat exchanger plate includes a peripheral edge, an internal fluid passageway configured to receive a second fluid. The internal fluid passageway includes an inlet and an outlet that open at the peripheral edge. The heat exchanger further includes a manifold having a supply chamber in fluid communication with the inlet of each heat exchanger plate and a discharge chamber in fluid communication with the outlet of each heat exchanger plate.

A cold plate assembly for cooling a battery of a vehicle includes a first exterior portion disposed adjacent the battery, a separator portion disposed adjacent the first exterior portion, a first flow path formed between the first exterior portion and the separator portion with the first flow path configured to receive a first fluid flow therein, a second exterior portion disposed adjacent the separator portion opposite the first exterior portion, and a second flow path formed between the separator portion and the second exterior portion with the second flow path configured to receive a second fluid flow therein. The first fluid flow flows relative to the second fluid flow in a counter-flow flow configuration.

A pin for a core layer of a heat exchanger, the pin being an additively manufactured pin having a sinusoidal shape between an upper and a lower sheet.

A heat exchanger (4) has fluid flow channels (6) with at least one heat exchanging surface (10) which has an undulating surface section for which the surface profile varies along a predetermined direction such that at a first edge (E1) the surface profile follows a first transverse wave (20), at a second edge (E)2 the surface profile follows a second transverse wave (22) and at an intermediate point I between the edges the surface profile follows a third transverse wave (24). The third transverse wave (24) has a different phase, frequency or amplitude to the first and second transverse waves so that chevron-shaped ridges and valleys are formed. This improves the mixing of fluid passing through the channel and hence the heat exchange efficiency.

Heat exchanger assemblies and methods are provided for cooling the interior of an enclosure (e.g., electrical cabinets, computer server racks, chemical chambers, and animal cages). Heat is transferred via thermal conduction from a first plurality of surfaces positioned inside the enclosure to a second plurality of surfaces positioned outside the enclosure. The first and second plurality of surfaces remain in thermal contact with one another during use. Heat is dissipated from the second plurality of surfaces to the ambient air outside the isolated environment without the ambient outside air mixing together with the air inside the enclosure. This, in turn, inexpensively removes heat from the air inside the enclosure and prevents contaminants from entering the enclosure.

An additively manufactured heat exchanger configured to transfer heat between a first fluid and a second fluid includes a first channel with a first wall configured to port flow of a first fluid and a second channel with a second wall configured to port flow of a second fluid. The heat exchanger also includes a barrier channel containing unprocessed build powder provided by the additive manufacturing process and is located between the first wall and the second wall. The barrier channel is configured to prevent mixing of the first fluid and the second fluid when one of the first wall and the second wall ruptures.

A heat dissipation device of an inverter is provided disclosed by the present application, which includes a heat sink base, a cooling module and a temperature equalizing plate arranged on the heat sink base. The cooling module is configured to dissipate heat from the heat sink base, the temperature equalizing plate is provided with a part mounting seat, and the heat sink base is arranged between the cooling module and the temperature equalizing plate. When in use, the heat sink base is mounted on the cooling module, the temperature equalizing plate is mounted on the heat sink base, and parts of the device are mounted on the part mounting seat.

A heat exchanger for providing thermal energy transfer between a first flow along a first flowpath and a second flow along a second flowpath has a plate bank having a plurality of plates, each plate having: a first face and a second face opposite the first face; a leading edge along the second flowpath and a trailing edge along the second flowpath; a proximal edge having at least one inlet port along the first flowpath and at least one outlet port along the first flowpath; and at least one passageway along the first flowpath. An inlet manifold has at least one inlet port and at least one outlet port. An outlet manifold has at least one outlet port and at least one inlet port. The first flowpath passes from the at least one inlet port of the inlet manifold, through the at least one passageway of each of the plurality of plates, and through the at least one outlet port of the outlet manifold and means linking distal portions of the plates.

To provide a vacuum pump capable of efficiently cooling electrical equipment.
