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.

The HE (heat exchanger) of automotive exhaust TEG (thermoelectric generator) plays a vital role in converting thermal energy into electrical energy, therefore achieves the goal of energy conservation and emission reduction. A new regular-octagon HE is modeled and simulated in FLUENT to obtain the velocity path-lines of fluid. Through simulation results, the velocity path-line is tracked and analyzed, in order to evaluate the fluid resistance and fluid turbulence intensity. By using control variable method, a variety of HE models with different structural parameters are modeled and simulated, to optimize the structure of HE. Eventually, it is intended to design a HE with proper fluid resistance and remarkable turbulence intensity.
