FPA 적외선 센서 냉각용 스털링 극저온 냉동기 개발

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 refrigerators have the compact structure and light weight. In this paper, integral Stirling cryocooler is designed, manufactured and fabricated, and performance characteristics are investigated. This cooler delivers approximately 0.6W cooling at 80K for 21W of input power from 24V DC power supply.
