Abstract
An exhaust system for an engine is disclosed herein. The exhaust system includes a catalytic converter, a heat collector downstream from the catalytic converter, and a heat transfer system receiving waste exhaust heat via a thermosyphon evaporator for storage and/or use in a cabin heating system. In this way, waste heat is utilized to provide better cabin heating, particularly at engine cold start.
Claims15
An exhaust system for an engine, comprising:
- a catalytic converter;
- a heat collector downstream from the catalytic converter;
- a thermosyphon evaporator including a plurality of heat pipes coupled to the heat collector;
- a first pipe coupling the thermosyphon evaporator to a heater core of an other system;
- and
- a second pipe coupling the heater core to the thermosyphon evaporator.
