Engine exhaust system having a thermoelectric conversion device and a heat pipe

摘要

Systems and methods for converting engine heat energy to electricity using a thermoelectric conversion device are provided herein. One example system may include an engine heat source, a thermoelectric conversion device for converting heat into electricity, and a heat pipe. The heat pipe is positioned so that when the temperature of the engine exhaust is too high, the excess heat may be transferred away from the thermoelectric conversion device to the heat sink via the heat pipe.
