Development of miniature pulse tube Cryocooler for Space applications

Abstract

Sumitomo Heavy Industries has developed cryocoolers for space application. In recent years, development of a compact and lightweight cryocooler with high cooling power is demanded. Therefore, we are working on the development of new model with greater cooling power than the current model. It is possible to shorten the development span by using a convenient numerical calculation method. In this paper, the comparison between calculation results using SAGE program and actual performance test results are introduced.
