摘　　要：基于多级斯特林制冷机或多级脉管制冷机预冷节流制冷循环的复合制冷机,结合了回热式制冷与等焓节流的各自优势,具有高效率、低振动、寿命长等优势,使其在深空探测领域受到越来越多的关注。简要介绍了复合制冷机的基本结构,重点概述了复合制冷机在2 K温区的国内外应用情况与研究进展。展望了这种极具潜力的低温制冷技术的未来发展趋势。A hybrid cryocooler based on the pre-cooled J-T throttling refrigeration cycle by the multi-stage Stirling cryocooler or multi-stage pulse tube cryocooler has the advantages of both regenerative cooling and throttling cooling, with high efficiency, low vibration and long life, so that it has been paid more and more attentions in the field of deep space exploration. The basic structure of the hybrid cryocooler was briefly introduced, the applications and research progresses of the hybrid cryocooler at home and abroad in 2 K temperature range were focused.The future development of the hybrid cryocooler was discussed.
