本文概述了一种称为“泵辅助毛细管相变回路”的新型两相回路，旨在解决回路热管中温度振荡和传热距离有限的缺点。所提出的环路是主动和被动系统的组合。它配备了平盘式蒸发器和提供毛细作用力的双孔吸液芯。此外，选择甲醇作为工作流体。在传热过程中，工质通过毛细管力和机械泵的驱动力进行传递。利用工作流体的显热和潜热来传递热量。通过补偿室的液体循环带走从蒸发器泄漏到补偿室的热量。测试结果表明，系统对可变热负载表现出非常快的响应，没有检测到明显的温度振荡。当机械泵输入功率为2 W时，在加热器表面温度低于80 °C时，系统可传递的最大热负荷增加至180 W（热通量= 17.7 W/cm2），传输距离为1850 mm。在散热器温度为-10 °C时，蒸发器热阻在0.298 K/W至0.196 K/W之间变化。
This paper presents an overview of a novel two-phase loop called “pump-assisted capillary phase change loop” designed to address the drawbacks of temperature oscillation and limited heat transfer distance in loop heat pipes. The proposed loop is a combination of active and passive systems. It is equipped with an evaporator designed in the type of flat-disk, and a biporous wick that provides the capillary force. In addition, methanol is chosen as the working fluid. During the heat-transfer process, the working fluid is transferred by both the capillary force and the driving force of the mechanical pumping. Both the sensitive and the latent heat of the working fluid are utilized to transfer heat. The liquid circulation through the compensation chamber takes away heat leak from the evaporator to the compensation chamber. Test results indicate that the system shows a very fast response to variable heat loads with no obvious temperature oscillation being detected. The maximum heat load the system could transfer increases up to 180 W (heat flux = 17.7 W/cm2) with transport distance of 1850 mm at the heater surface temperature below 80 °C, when the power input of the mechanical pump is 2 W. The evaporator thermal resistance varies between 0.298 K/W and 0.196 K/W at the heat sink temperature of −10 °C.
