Thermal Optimization of Exhaust-based Thermoelectric Generator

摘要：

　　The potential for automotive exhaust heat based thermoelectric generator (TEG) has been increased with continuously advances in thermoelectric technology.The thermal performance of the heat exchanger in exhaust-based TEG was analyzed.In terms of interface temperature and thermal uniformity,the thermal characteristics of the heat exchangers with different internal structures,materials and thicknesses were discussed.CFD simulations and infrared experiments on a high-performance production engine with a dynamometer were carried out.It was proved that the plate-shape heat exchanger made of brass with internal baffles and the thickness of 3mm,obtained a relatively optimal thermal performance,and it will help to improve the thermal performance of the TEG.
