DECREASED HOT SIDE FIN DENSITY HEAT EXCHANGER

摘要

Apparatus and method for cooling heated fluids, such as exhaust gases, flowing through a heat exchanger including at least one exhaust gas plenum with fins or other heat transfer structure and at least one coolant plenum, and providing decreased heat exchange in that portion of the exhaust gas plenum contacting the inlet thereof by decreasing the fin or heat transfer structure density in such portion relative to the remainder of the exhaust gas plenum.
