Patent ID: 8646516

Claim:
A heat exchanger selected from the group of vehicular heat exchangers consisting of exhaust gas cooler and charge air cooler, the heat exchanger comprising: a plurality of stacked, alternating first and second heat exchange plates of inverted U-shaped cross-section, said first and second plates having closed peripheral side walls and open ends; the open ends of said first plates being oriented at 90° to the open ends of said second plates; the sidewalls of said first and second plates having end portions, the end portions in adjacent first and second plates being aligned to form corners of the heat exchanger; opposed U-shaped bodies having open ends and lateral walls joined in a liquid tight manner to the aligned first and second plate sidewall end portions; end plates closing the open ends of said U-shaped bodies to form manifolds for the flow of liquid through the plate open ends of said second plates; and said manifolds defining inlet and outlet openings for the flow of liquid into and out of the heat exchanger.
