Abstract: A heat exchanger for thermal management of battery units made-up of plurality of battery cells or battery cell containers housing one or more battery cells. The heat exchanger has a main body portion defining at least one primary heat transfer surface for surface-to-surface contact with a corresponding surface of at least one of the battery cells or containers. A plurality of alternating first and second fluid flow passages are formed within the main body portion each defining a flow direction, the flow direction through the first fluid flow passages being generally opposite to the flow direction through the second fluid flow passages providing a counter-flow heat exchanger. In some embodiments the heat exchanger has two pairs of inlet and outlet manifolds, the heat exchanger providing a single-pass, counter-flow arrangement. In other embodiments the first and second fluid flow passages are interconnected by turn portions forming a U-flow, counter-flow heat exchanger.

Abstract: A heat exchanger having a conical-shaped core is disclosed. A first set of flow passages is formed between mating conical-shaped core plates, the mating plates forming plate pairs that are spaced apart from each other forming a second set of flow passages therebetween. A pair of oppositely disposed fluid openings are provided for inletting/discharging a fluid to/from the heat exchanger in a co-axial manner, the fluid openings being interconnected by a pair of fluid manifolds formed in the outer perimeter of the core, the second set of flow passages and a fluid manifold formed centrally through the heat exchanger. A second set of inlet/outlet manifolds formed within the perimeter of the core are interconnected by the first set of flow passages. Flow through the first set flow passages is peripheral around the perimeter of the conically-shaped core plates while flow through the second set of flow passages is along the angle defined by the conical-shaped plates.
