Summary

Stirling cryocoolers have been widely used for the cooling of infrared sensors and high temperature superconducting filters to the temperature of the liquid nitrogen. The Stirling cryocooler with the rotary compressor is applicable to the cooling device for the compact mobile thermal imaging system, because the cryocoolers have the compact structure and light weight. This paper presents the design, manufacturing process and test results in the optimum design and operating condition for the rotary type Stirling cryocooler designed and manufactured by KIMM and Nexen. The prototype has achieved no load temperature of 50 K and cooling capacity of 0.6 W at 80 K for 20 W of input power. Tests performed on this cooler have been successful with a measured cooldown time to 80 K of less than 5 minutes 24 seconds for 71°C ambient temperature with input power of 12 W.
