摘要
机械制冷是指需要输入外功的闭式循环主动制冷过程。由于空间环境的特殊性,机械制冷技术在空间遥感领域的应用除了需满足微型、轻量、长寿命、低功耗、低振动、低电磁干扰等严格的要求外,还必须通过热真空、力学、电磁兼容等多种苛刻的空间环境试验的考核,具有足够的空间环境适应性。分析了机械制冷技术如何满足空间遥感的特殊要求,并介绍了作为当前研究热点的新型空间机械制冷技术。
The mechanical cryocoolers must possess enough adaptability to the tough space environment in practical space application.In this paper,ways to make sure the space use of mechanical cooler were discussed,and two kinds of new mechanical coolers were also introduced to the future space borne remote sensing instrument.
