摘要
简要介绍了国内外 G- M制冷机的应用、发展背景、工作原理。由于 G- M制冷机有性能可靠、寿命长、振动小、温度低、冷量大等优点 ,在多种领域得到广泛的应用。文中进一步说明了实验室测定二级 G- M制冷机制冷量的方法 ,及所用的设备、材料 ,对测试结果进行分析 ,为进一步改进奠定基础。文中二级 G- M制冷机性能指标为 :>6 W/ 2 0 K,降温时间为 6 0 m
Based on the development situation of G-M cryocooler, the measurement method of capacity in the laboratory is clarified. The capacity of the cryocooler's is beyond 6W/20K and its cooldown time is about 60min which can supply reference for the improvement of the G-M cryocooler structure. G-M cryocooler is widely used because its advantage such as low vibration, high dependence, low temperature, high capacity etc. In a word, the future for the G-M cryocooler is bright.
