Abstract

In this paper, a cooling system that includes a heat spreader and a natural convective heat sink is proposed for the cooling of a concentrating photovoltaic (CPV) module. The heat spreader and the natural convective heat sink are designed on the basis of previous analytical investigations. In order to evaluate the proposed cooling system, we conducted experimental investigations varying the heat rate and the inclined angle of the cooling system. From the experimental results, it is found that the proposed cooling system satisfies the design constraints for good operation of the CPV module. Finally, a correlation is suggested for estimating the effects of the heat rate and the inclined angle on the thermal performance of the natural convective heat sink is suggested.

본 연구에서는 열분산기 및 자연대류 히트 싱크로 구성된 집광형 태양전지 모듈용 냉각 장치를 제안하고자 한다. 이를 위해, 기존 연구자들의 해석적 연구를 바탕으로 집광형 태양전지 모듈용 열분산기 및 자연대류 히트 싱크를 설계하였다. 제안된 냉각 장치의 성능을 평가하기 위하여, 발열량과 수직 기준 경사각 변화에 따른 열성능 평가실험을 수행하였다. 실험결과로부터, 제안된 냉각 장치가 집광형 태양전지 모듈의 설계 조건을 만족하는 것을 확인하였다. 마지막으로 발열량과 수직기준 경사각 변화에 따른 자연대류 히트 싱크의 열성능을 예측할 수 있는 상관식을 제시하였다.
