本文针对一款厚度为8 mm小型平板环路热管进行了实验研究,该热管的毛细芯由铜粉烧结而成,采用水作为工质,蒸发器及管线均由铜制成,分析了不同冷凝位置对环路热管传热特性的影响。研究表明冷凝器位置越靠近蒸发器出口,环路热管启动性能越好,最大热负荷也越大,但低功率时运行温度会较高,而冷凝器位置靠近储液室时,热管表现出与前者相反的传热特性。 In this paper, an experimental study of a small flat-plate loop heat pipe with a thickness of 8 mm was carried out. The capillary core of the heat pipe was sintered by copper powder. Water was used as the working fluid. Both the evaporator and the pipeline were made of copper. Effect of Location on Heat Transfer Characteristics of Loop Heat Pipe. The results show that the closer the condenser is to the outlet of the evaporator, the better the starting performance of the loop heat pipe is and the greater the maximum heat load, but the operating temperature is higher at low power. When the condenser is close to the reservoir, The former has the opposite heat transfer characteristics.
