Abstract
A heat exchanger has a pair of opposed walls and an interior space between the walls, and first and second areas located on opposite sides of a longitudinal axis, each adapted for thermal contact with a battery cell. Inlet and outlet ports are provided in the respective first and second areas, and a flow barrier extends along the longitudinal axis and separates the first and second areas. Fluid flow passages are defined in the first and second areas. A first crossover passage extends across the longitudinal axis from the inlet port to an inlet flow passage in the second area. A second crossover passage extends across the longitudinal axis from an outlet flow passage in the first area to the outlet port. A crossover housing is provided inside or outside the interior space and extends across the longitudinal axis, enclosing at least one of the first and second crossover passages.
