空间应用机械制冷机是将光学探测器、望远镜和热防护屏冷却到100 K以下的有效方法。20 K级双级斯特林循环制冷机在20 K时的制冷功率为200 mW，寿命为1.5年，最初是为2006年发射的日本红外望远镜卫星AKARI的冷却部件而开发的。基于该AKARI制冷机，通过1）第二级优化的8 mm直径置换器，2）用于置换器支撑的柔性轴承和3）低放气材料的选择和最佳烘烤工艺的研究，以开发第二代双级斯特林制冷机，用于下一个创新的天文使命，如ASTRO-H/SXS（2015）和SPICA（2022）。利用EM（工程模型）进行了验证试验，在第二冷级和第一冷级分别获得了17.6K和96.1K的最大制冷功率，最大制冷功率分别为200 mW和1000 mW，并有一定的裕度。并进行了机械性能测试，证明了ASTRO-H/SXS合格水平的机械环境的耐受性。持续运行以验证超过3年的规定寿命仍在测试中，截至2012年8月，已达到总计13545小时（约560天）。
Mechanical cryocooler for space application is efficient way to cool down the optical detector, telescope and thermal shields to cryogenic temperature below about 100 K in the aspect of mass and size. The 20 K-class double-stage Stirling cycle cryocooler with cooling power of 200 mW at 20 K and lifetime of 1.5 years was originally developed for a cooling component of the Japanese IR telescope satellite AKARI launched in 2006. Based on this AKARI cryocooler, improvements with higher cooling performance and reliability with 1) the optimized 8-mm diameter displacer at second stage, 2) the flexure bearings for displacer supporting and 3) selection of low-outgassing materials and optimal baking process were investigated to develop the second-generation double-stage Stirling cryocooler for application to the next innovative astronomy mission such as ASTRO-H/SXS (2015) and SPICA (2022). The verification tests by using the EM (Engineering Model) were performed and maximum cooling power of 17.6 K with 200 mW at the 2nd cold stage and 96.1 K with 1000 mW at the 1st cold stage was obtained with margin. Mechanical performance test was also carried out and proved tolerability for mechanical environment of qualification level of ASTRO-H/SXS. Continuous running to verify specified lifetime of over 3 years is still under testing and 13545 hours (~ 560 days) in total has just achieved as of August 2012.
