本文介绍了一种具有两个蒸发器和两个冷凝器的微型循环热管（MLHP）启动特性的试验结果。通过改变一个或两个蒸发器的热负荷，冷凝器水槽温度，以及有无补偿室（CC）温度控制，进行了MLHP启动试验。在水平位置进行了90多次启动试验，均取得了成功。试验结果表明，在热负荷为1W至100W的情况下，MLHP启动稳健。热负荷一施加，循环就开始，没有大的温度超调。验证了热电转换器（TEC）对CC主动控温启动的有效性和良好的可重复性。回路的能力，以寄生热增益开始由冷却的CC温度低于环境温度也证明了。
This paper presents the test results on start-up behaviors of a miniature loop heat pipe (MLHP) with two evaporators and two condensers. The MLHP start-up tests were conducted by varying the heat load to one or both evaporators, the condenser sink temperatures, and with or without compensation chamber (CC) temperature control. More than 90 start-up tests have been conducted in horizontal position, and all were successful. Test results showed robust start-ups of the MLHP with heat loads of 1W to 100W. Loop started as soon as the heat load was applied, without a large temperature overshoot. The efficacy and good repeatability of the start-ups with CC active temperature control by using thermoelectric converter (TEC) was demonstrated. The ability of the loop to start with parasitic heat gain caused by cooling the CC temperature below ambient temperature was also demonstrated.
