Abstract: A heat exchanger may include a perforated plate having a plurality of openings sandwiched between a first plate and a second plate. The first plate may have a first plate central planar surface, a first plate peripheral wall extending from an internal face of the first plate central planar surface towards the second plate, and an inlet permitting fluid flow on to the internal face of the central planar surface. The second plate may have a second plate central planar surface, a second plate peripheral wall extending from an internal face of the second plate central planar surface towards the first plate, and an outlet permitting fluid to exit the heat exchanger. The first plate, the second plate and the perforated may be coupled and define a fluid passage for flow of a heat exchanger fluid from the inlet to the outlet.

Abstract: Systems are provided for a heat exchanger assembly. In one example the system may include a top plate, a fluid inlet and a fluid outlet, a bottom plate coupled to the top plate, a perforated plate positioned between the top plate and the bottom plate having an underside facing the bottom plate and including perforations shaped to generate an impingement jet onto the bottom plate, and at least one of the following: the top plate comprising a portion being inclined with respect to a longitudinal axis of the heat exchanger assembly; the perforated plate being inclined with respect to the longitudinal axis or a lateral axis of the heat exchanger assembly; and the heat exchanger assembly further comprising a flow control plate.

Abstract: Methods and systems are provided for heat exchangers including a first outer plate, a second outer plate, and an intermediate plate. The intermediate plate is positioned between the outer plates. Fluid flow passages are formed between the intermediate plate and each of the outer plates.

Abstract: A cold plate heat exchanger for battery thermal management has first and second plates defining a plurality of fluid flow passages, with inlet and outlet ports proximate to a first end thereof. Each fluid flow passage has first and second ends communicating with respective inlet and outlet ports. One or more portions of each fluid flow passage are immediately adjacent to and in close proximity to a portion of another fluid flow passage or channel, such that heat energy will be transferred by conduction through the first and second plates between the fluid flow passages or channels, thereby providing enhanced heat transfer. The fluid flow passages or channels may be separated by a distance which is less than a width of one of the fluid flow passages or channels, and may be separated by a single rib which partially defines each of the fluid flow passages or channels.

Abstract: A heat exchanger adapted to support a plurality of battery cells on the outer surface thereof is disclosed. The heat exchanger includes first and second plates disposed in opposed, facing relation to one another such that portions of the inner surface of the first and second plates are spaced apart from one another. A manifold region is enclosed between the first and second plates for receiving an incoming heat transfer fluid. A main fluid flow region is enclosed between the first and second plates and is configured for receiving heat transfer fluid discharged from the manifold region and transmitting the heat transfer fluid through the heat exchanger to an outlet port. At least one bypass port for establishing fluid communication between the manifold region and the main fluid flow region is disposed at a location within the manifold region that is upstream of the manifold region outlet end.

Abstract: A heat exchanger includes first and second plates joined together with portions of the inner surfaces spaced apart to define a plurality of fluid flow passages for flow of a heat transfer fluid. A dividing rib separates the heat exchanger into an inlet section and an outlet section, each of which includes a plurality of fluid flow passages. Inlet and outlet ports are located near a first end of the heat exchanger, on opposite sides of the dividing rib. The heat transfer surface area of the inlet section is less than that of the outlet section due to the presence of one or more flow obstructions between the inlet port and first ends of the fluid flow passages in the inlet section. Each flow obstruction may be a dead channel including a continuous outer rib completely surrounding a depressed middle region.
