【Abstract】 A 4W/80K Integral Stirling Cryocooler was introduced in this paper, Not only it can be successfully applied to the research for superconducting filter and superconducting delayline, etc, but also can it be used to the field of high-temperature superconduct or and low-temperature physical nature test, It has been described for the thermodynamic designing principle by identical-temperature mode and the coaxial structure of compression piston and displacer,The characteristics of cryocooler (curve of cooldown time vs temperature, curve of cool-ingcapacily vs temperature, curve of cooling-capacity vs inflation pressure) were analyzed at last.更多还原
