论述了用于稀释制冷机的热交换器,提出了热交换器的关键问题是卡皮查热阻和粘性加热。并具体介绍了几种典型的用于稀释制冷机的热交换器及目前世界上最先进的分离型热交换器。同时对海绵状体多孔表面的制造工艺也作了简单的阐述。图4。 The heat exchanger used to dilute the refrigerator is discussed. The key problems of the heat exchanger are proposed as the Capillary thermal resistance and viscous heating. And introduced several typical heat exchangers for dilution refrigerators and the most advanced separable heat exchangers in the world. At the same time, the manufacturing process of the sponge-like porous surface is also briefly described. Figure 4.
