Abstract
A heat exchanger suitable for cooling exhaust gases and a method of making same are disclosed. The heat exchanger includes an outer casting member having first and second ends and forming a housing and a plurality of channel members forming alternating first and second flow channels for the flow of an exhaust gas through the first flow channels and coolant through the second flow channels. The channel members form a core having first and second ends, this core being mounted in the casting member. A first flange is fixedly attached to a first end of the core so as to form a sealed joint. A second flange is fixedly attached to the second end of the core so as to form another sealed joint. The first and second flanges are each coupled by fasteners to their respective ends of the casting.
