초록

국내 사용되고 있는 적외선 검출기 냉각용 스털링 극저온 냉동기는 상당부분 수입에 의존하고 있으며, 높은 대당 가격, 제한적인 수명 및 내구성 부족으로 지속적인 극저온 냉동기 수요가 발생하고 있다. 그런데 적외선 검출기용 극저온 냉동기 기술은 국방, 우주관련 기술로 선진국의 기술이전이나 공동 개발이 매우 제한적이다. 본 연구를 통해 개발하고자 하는 맥동관 극저온 냉동기는 저온구동부의 기계적 피스톤을 가스피스톤으로 대체하고, 압축방식을 선형압축방식으로 바꿈으로써 낮은 진동, 높은 수명 및 내구성을 확보할 수 있다. 이를 통해 맥동관 냉동기의 기술수준을 선진국에 근접시키고, 독자적인 냉각형 적외선 검출기 설계 및 제작기술에 대한 기술을 확보하고자 한다.

Most of the Stirling cryocoolers used for infrared detector cooling in domestic is imported. Because the cooler has a high price, short life and poor durability, demand for the coolers continues steadily. However, the cooler is highly related to defense and space technology, technology transfer or co-development with the countries having experties in cooler design is very limited. The pulse tube cooler to be developed in this study is such that the mechanical piston in low temperature actuating part is replaced by the gas piston and linear compressor is adopted, which results in low vibration, long life and better durability. It is expected that development of the pulse tube cooler will not only improve our technology to the level of advanced countries, but also enhance the skills in designing and manufacturing of the infrared detector.
