ＣＰＬ热控系统由于其独特的运行优势，在航天热控系统及微电子冷却装置等应用中越来越受到人们的重视．多孔芯冷凝器的提出很好地解决了压力波动和启动困难问题，目前关于这方面的研究尚处于初级阶段．本文试图建立多孔芯冷凝器冷凝通道内的流动和换热模型，探讨各影响因素对凝结换热过程的作用机制，并通过多孔芯冷凝器内部工作状况的可视化实验结果验证了理论模型的合理性。
Due to its unique operating advantages, CPL thermal control systems are gaining more and more attention in aerospace thermal control systems and microelectronic cooling devices. The proposal of porous core condenser solves the problem of pressure fluctuation and start-up very well. At present, the research on this aspect is still in its infancy. This paper attempts to establish the flow and heat transfer model in the condensation passage of the porous core condenser, and discusses the mechanism of the various factors on the condensation heat transfer process. The experimental results of the internal working conditions of the porous core condenser verify the rationality of the theoretical model .
