A battery heat exchanger for a vehicle may include a first outer plate; a second outer plate positioned in parallel with the first outer plate; a fluid inlet; a fluid outlet; and an intermediate plate positioned between the first outer plate and the second outer plate, the intermediate plate comprising a rib to separate an inlet portion from an outlet portion of the heat exchanger; and a plurality of corrugations with openings for thermal exchange medium fluid flow, where the corrugations have different orientations and lengths.
