Abstract
A cooling system for engine exhaust gases includes a engine block mounted exhaust manifold connected to a heat exchanger by a conduit and gas distribution header, the exhaust manifold, conduit and distribution header being continuously water jacketed to shield all hot exhaust system surfaces for engine operation in flammable or explosive environments. The exhaust gas flows through parallel gas tubes in the heat exchanger having thin, corrugated walls which aid heat transfer to the surrounding water and are axially expandable to relief thermal stress.
