Description

Shanghai Institute of Technical Physics (SITP) of the Chinese Academy of Sciences (CAS) has been engaging in the development of space long-life cryocooler for over 30 years. The three typical cryocooler (pneumatic Stirling cooler, Stirling cooler and pulse tube cooler) were all developed simultaneously. In 2002, a self-developed pneumatic Stirling cryocooler operated in orbit successfully in China for the first time. This paper reviews the performances and the applications of the mature long-life cryocooler at SITP. A 45 K dual-drive Stirling cryocooler, a 80 K pneumatic Stirling cryocooler (total weight 900 g) and several inertance pulse tube cryocoolers (170 K, 90 K, 60 K, 40 K, 30 K) are introduced in detail. The reliability and high efficiency of SITP's space long-life cryocoolers (all three types) have been verified in the space applications. Some researches on the large cooling capacity, the size miniaturization, and the deep low temperature mechanical cryocoolers at SITP are also mentioned. The developed and developing cryocoolers can meet the cryogenic requirement of China’s current and future space applications.
