Space optoelectronic detectors present demand for the cryogenic environment that can operate stably and efficiently. Stirling, pulse tube and JT cryocoolers (SC, PTC and JTC) are capable of space applications, which have been verified and put into space use for many times. Shanghai Institute of Technical Physics, Chinese Academy of Science (SITP, CAS) has developed many space cryocoolers for decades. Multistage cryocoolers coupled by the Stirling technology, pulse tube technology and JT technology can satisfy the needs of the 2-30 K cryogenic enverionment in the space applications. This paper introduces the typical cryocoolers operating from 2 K to 30 K, which are important technologies and development tendency for the future space applications. |
