열발전소자를 이용한 전력변환장치의 성능 평가

Abstract

This study was performed to verify performance of power conversion device, which could product small scale power, using waste heat and thermoelectric generator. For this purpose, after conducting the analyses of thermal stress and thermal flow on power conversion device, experimental apparatus as well as power conversion device was manufactured and then its performance was tested. As for the results of analyses, it was confirmed that high temperature part of power conversion device was safe in case of maximum 160℃ for thermal stress. As for thermal flow, case of Input A was shown more vortex and large flow velocity than case of Input B due to influence of internal structure of power conversion device. As for experimental results, the power in case of water-cooling, which showed 5.31 volts as maximum power, was about 9∼13 times higher than case of air-cooling.
