Abstract

The thermoelectric generator (TEG) is commonly used to harvest or scavenge the remnant energy from waste heat sources, such as automotive exhaust systems, cooling line of power plants, ocean temperature difference, human body, and industrial processes. The performance of TEG depends on the thermoelectric material and its structural configuration. To obtain the maximum power from TEG module, the optimal design of heat exchanger is required to realize the full potential of power generating system. The internal structure of heat exchanger plays a critical role to determine the efficiency of TEG by enhancing heat transfer between the hot and cold sides of the TEG module. We studied the effect of internal fin structure in heat exchanger with hot water feeding condition to obtain the best performance of TEG module array by using computational simulations and compared with the experimental results.
