Abstract
A heat exchanger for cooling battery cell containers in a battery unit is disclosed. The heat exchanger includes individual heat exchanger modules that are fluidly interconnected and spaced apart from each other so as to accommodate individual battery cell containers arranged between adjacent heat exchanger modules to form a battery unit. Each heat exchanger module is formed by a pair generally planar first and second heat exchanger plates having a main section and flexible inlet and outlet panels extending therefrom. The heat exchanger is formed by a stack of alternating first and second plates that are brazed together to form heat exchanger modules, the heat exchanger modules formed in the stack being interconnected by their inlet and outlet panels and expanded post-brazing by bending/flexing the inlet and outlet panels to provide adequate spacing or gaps between the modules to accommodate battery cell containers.
