US Patent 11326837 Heat exchanger with internal manifold structure

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.
