RECENT DEVELOPMENT OF STIRLING TYPE PULSE TUBE CRYOCOOLER

The recent advances in Stirling type pulse tube cryocooler are reviewed.Compared with Stirling cryocoolers,pulse tube cryocoolers has advantages of life,reliability and vibration because of no moving parts in the cold head.With the understanding of the D C flow and the applying of the double-inlet and inertance tube,the efficiency of the pulse tube cryocooler is matching or exceeding that of Stirling cryocoolers.Stirling type pulse tube cryocooler will have a great use in cooling infrared sensors and superconductors for space and military applications.
