Abstract
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.
