Abstract

The enhancement for cooling performance of heat sink is surely necessary to guarantee the performance of electronic products. So in this paper, the cooling performances of the aluminum heat sink with pulsating heat pipe(PHP) were investigated experimentally and numerically. The pulsating heat pipe was used as a heat spreader. Working fluid of PHP was R-22. Heat inputs were 30W, 60W, 80W and 100W, respectively. Heat sink was tested for forced convection conditions with air velocity of 1 ~ 4m/s. And CFD simulations were conducted for two different heat sinks. The results showed that the cooling performance of heat sink with pulsating heat pipe was higher than that of conventional heat sink. Therefore, the pulsating heat pipe can be a good tool to improve cooling performance of heat sink.

열전소자를 이용한 냉각 장치에 있어서 열전소자발열부측의 제거 열량은 제품의 성능 및 적용범위를 결정하는 주요변수가 되므로 히트싱크의 열저항을 최소화 할 수 있는 최적 조건의 히트싱크 설계를 필요로 한다. 발열부가 작고 상대적으로 히트싱크 면적이 커서 히트싱크 전체면으로 열확산이 필요한 경우 히트싱크의 방열 성능을 향상시키기 위하여 작동유체 R-22의 진동형 히트파이프를 이용하여 열전소자의 발열부측의 발열량(30W, 60W, 80W, 100W)과 공기 유속(1~4 m/s)에 따른 히트싱크의 열저항 실험 및 수치해석 결과와 비교 분석을 통해 히트싱크의 냉각 성능을 향상 시킬 수 있는 방법을 연구하였다.
