【Abstract】 In this paper,experimental results of a miniature two-stage Stirling cryocooler are.introduced.The influence of filling gas pressure and refrigeration temperature on the the refrigerating capacity along with the relationship between parameters,has been measured.The valley pressure corresponding to the lowest refrigeration temperature and the cooldown time versus operating pressure have been discussed.The coefficient of performance and thermodynamic efficiency of the cryocooler have been calculated based on experimental data.更多还原
