The Numerical Analysis of the Two-Phase Closed Thermosyphon Under the Best Working Condition

为了提高两相闭式热虹吸管的传热效率,在不同工作情况下利用FLUENT模拟软件对两相闭式热虹吸管进行数值模拟,主要考察两相闭式热虹吸管蒸发段的壁温、充液率对传热效率的影响。结果表明,当两相闭式热虹吸管的蒸发段壁温为570K,并且其蒸发段的充液率为50%时,两相闭式热虹吸管的传热效率最佳。

In order to improve the heat transfer efficiency of the two-phase closed thermosyphon,different working conditions of the two-phase closed thermosyphon under different working condition were simulated by the FLUENT software.Including, the two-phase closed thermosyphon under the working condition of different influence of wall temperature of the evaporation zone,and the different filling factor of the evaporation zone on heat transfer efficiency was studied.The results showed that when the wall temperature of the evaporation was 570 K and the filling factor of the evaporation was 50%,the best heat transfer efficiency of the two-phase closed thermosyphon was best.
