摘　　要：随着对空间制冷的要求越来越高,具有多级制冷能力的制冷机比使用多个制冷机有更高的系统效率。这种制冷机通过减小冗余提高系统的可靠性,同时又满足了空间低温系统集成化的需求。针对单个线性压缩机驱动多个膨胀机的方式,总结分析其在多温区多冷量需求下的制冷效果和发展前景。As the future space refrigeration demand becomes higher and higher,the refrigerator with multiple refrigeration capacity is more efficient than multiple refrigerators.By reducing the redundancy,this kind of cryocooler not only improves the reliability of the system,but also meets the urgent need about integration of the cryogenic system.In this paper,according to different structure of stirling type cryocooler driving multiple expanders with single linear compressor,we summarize and analyze its refrigeration effect and prospects.
