Abstract

This paper reports the generation efficiency and the thermal performance of a thermoelectric generator (TEG) harvesting energy from the waste heat of high power electronic components. A thermoelectric (TE) model containing thermal boundary resistances is used to predict generation efficiency and junction temperature of a high power electronic component. The predicted results are verified with measured values, and the discrepancy between prediction and measurement is seen to be moderate. The verified TE model predicts generation efficiencies, junction temperatures of the component, and temperature differences across a TEG at various source heat flows associated with various electrical load resistances. This study explores effects of the load resistance on the generation efficiency, the temperature difference across a TEG, and the junction temperature.

본 논문은 고파워 전자소자의 폐열로부터 에너지 수확을 목적으로 하는 열전생성기의 생성효율과 열적 성능에 대하여 논한다. 열경계저항을 포함하는 열전모델이 적용되어 생성효율과 고전력 전자소자의 junction 온도를 예측하였고 그 결과는 실험치로 검증되어진다. 검증결과는 예측치와 계측치의 오차가 작음을 보인다. 검증후 열전모델은 다양한 로드저항과 열원의 열율에서 생성효율, 열전생성기 양면의 온도차, 소자의 junction 온도를 예측한다. 본 연구는 로드저항이 생성효율, 열전생성기 양면의 온도차, junction 온도에 미치는 영향에 대해서도 탐구한다.
