초록

본 연구는, 증발부에 핵비등 전열 촉진면을 사용하여 수평상태에서도 작동 가능한 고성능 버블젯 루프 히트파이프(BJLHP)의 개발에 관한 것이다. 비등 촉진 전열면은 소결관과 GEWA-T 전열관을 사용하였으며, 평활관을 사용한 BJLHP와 유효열전도도를 사용하여 열성능을 비교, 검토하였다. 작동유체로는 R-141b를 사용하였으며, 충전량은 BJLHP 내부 체적의 50%, 입열량은 75W와 100W로 하였다. 그 결과 소결관을 사용한 BJLHP의 열성능이 가장 우수한 것으로 나타났으며, 소결관을 사용한 BJLHP의 유효열전도도가 평활관 BJLHP보다 300% 이상 향상되었다.

In this study, a high performance Bubble Jet Loop Heat Pipe (BJLHP) was developed using the enhanced nucleate boiling surfaces in an evaporating section. A sintered tube and GEWA-T(Wieland) tube were used enhance nucleate boiling. The thermal performance of these BJLHP was compared with the conventional smooth tube BJLHP with an effective thermal conductivity. This experiment was conducted under the following conditions : working fluid, charging ratio and input power of R-141b, 50%vol., 75W and 100W, respectively. As a result, the effective thermal conductivity of BJLHP with a sintered tube in the evaporating section was 300% higher than the smooth tube BJLHP.
