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.

This research studies the alternative way of electricity generating from the waste heat of economy oven by using 4 modules of thermoelectric modules. The hot side of thermoelectric module is attached to the heat plate while the cold side is installed on the rectangular, plate-fin heat exchanger. Variety of system adjustments were used during this study in terms of finding the maximum electric power rate. Adjusting the heating value and the electrical resistance to the thermoelectric was the procedure in this study. From the research, we found out that at the temperature of 200°C on the heat pad, the released maximum electric current was 4.5 W. The percentage of heat converting to electric current was 11.9%, with the 0.84 A and 5.35 V. The efficiency of the economy oven was 23.20%, and comes up to 23.39% while generating power via thermoelectric module.
