Abstract

An exhaust gas recirculation cooler includes an inlet configured to receive exhaust gas from an engine, an outlet configured to direct the exhaust gas back toward the engine, and an exhaust gas flow conduit. The flow conduit includes a first end adjacent the inlet, a second end adjacent the outlet, a first narrow side, a second narrow side, substantially flat broad sides extending between the narrow sides, a first channel adjacent the first narrow side and extending between the ends, a second channel adjacent the second narrow side and extending between the ends, and a plurality of third channels located between the first and second channels and extending between the ends. A plate is located at one end of the flow conduit to inhibit the exhaust gas from flowing through at least one of the first channel and the second channel while allowing exhaust gas flow through the third channels.
