저온 폐열 회수를 위한 열전소자기반 에너지 하베스터의 실험적 성능 분석

Abstract

The purpose of this paper is to confirm the variation of heat recovery performance about the proposed thermoelectric energy harvester by the direction of hot and cold fluid. Thermoelectric modules and water blocks were used to realize the proposed thermoelectric energy harvester. Heating coil and chiller were used to realize waste heat. The power generation was verified by applying the same temperature of hot and cold water to the thermoelectric energy harvester with the parallel flow and the counter flow. The results showed the most influential variable is the temperature difference. Depending on the direction of the fluid flow, the voltage of the counter flow was 60% higher than that of the parallel flow.
