| Abstract: | The recent development of large capacity Stirling-type pulse tube cryocoolers(LCSPTCs) was reviewed.The mechanisms of losses in regenerator and pulse tube were discussed and typical experimental methods employed to minimize these losses in LCSPTCs were listed.Developing a more rational mathematical mode to simulate losses in regenerator and pulse tube and design LCSPTCs in a more elaborate way has become the main challenge in the research of LCSPTCs. |
