Abstract

ABSTRACT Thermoelectric generation (TEG) is one of the most effective technologies converting heat directly into electric power. In this paper, a nearly kilowatt class TEG system mainly based on radiation heat transfer was designed and built. The open circuit voltage, the output power, the power density, and the conversion efficiency of the TEG system were investigated in detail at different temperature gradients. The maximum inverter power output of the TEG system assembled with 182 TEG devices can reach 684 W at a temperature difference around 125 K, and the corresponding power density can reach 845 W/m2. The inverter output power is almost proportional to the temperature difference between the hot and the cold side of TEG system. Our results confirmed that if the waste heat resource was sufficient to provide a greater temperature difference of 200 K in practical application, the output power and the power density of this TEG system would reach 1.23 kW and 1.51 kW/m2, respectively.
