【摘要】：為冷卻某空間用紅外探測器,研制了一臺斯特林型脈沖管制冷機。該制冷機為單級同軸型結(jié)構(gòu),整機重量4.5 kg,設計壽命5年。系統(tǒng)介紹了脈沖管制冷機系統(tǒng)結(jié)構(gòu)及實驗裝置,測試了制冷機性能及其與杜瓦耦合后的降溫特性曲線,實驗結(jié)果表明,脈沖管制冷機在80 K可提供0—3 W制冷量,比卡諾效率11%,其制冷量可充分滿足杜瓦組件的低溫和長壽命的工程需求。
[Abstract]:In order to cool a space infrared detector, a Sterling pulse tube refrigerator is developed. The refrigerator is a single-stage coaxial structure with a design life of 4.5 kg,. The system structure and experimental device of pulse tube refrigerator are introduced systematically. the performance of the refrigerator and the cooling characteristic curve coupled with Dewar are tested. the experimental results show that the pulse tube refrigerator can provide 0 鈮，
