Abstract:Stirling-type pulse tube cryocoolers have become a research hotspot in recent years because of their obvious advantages of high efficiency, high reliability and long lifetime in space applications. The recent research advance in the Stirling-type pulse tube cryocoolers for space application at home and abroad is analyzed. The application prospect and development trend of Stirling-type pulse tube cryocoolers are described. Finally, the current status and key technologies of 100-Hz pulse tube cryocoolers are reviewed.
