Thermal and power generating performances of thermoelectric energy recovery modules

This paper seeks to demonstrate the performance of a thermoelectric energy recovery module (TERM). The TERM aims to convert the waste heat from power amplifier (PA) transistors into the useful power. The TERM contains a thermoelectric generator (TEG), a heat spreader, and a heat sink. A first order prototype of the TERM is generated and used as a test vehicle. Experimental setup mainly consists of a test vehicle, a portable wind tunnel, and measurement tools. Thermal performances and power generations of the TERM are monitored at various source heat flows. The effects of a load resistance to power generation as well as thermal performance are also explored by conducting an experimental parametric study.
