摘要
本文介绍了一种小型二级整体式斯特林制冷机,该机在35K时有1W以上的制冷量,无负载最低温度约为20K。本文同时介绍了典型实验数据及性能曲线。作者主要分析了死体积、平均压力、运转频率和泄漏对实际制冷量的影响。这种机器采用无油润滑并已付诸也用,该机已运转了数百次,只有较好的重复性,可满足激光及高T_C超导研究的有关应用。
A miniature two stage integral Stirling cryocooler with cooling power over 1W at 35K is described. It is an unlubricated machine and can be put into operation, The lowest temperature is about 20K, Typical experimental data and curves are given. The evaluation of the effect of dead space, average pressure, operating frequency and leak on actual cooling capacity has been conducted.The machine has worked for hundred of times. The repeatability is excellent. The cooling requiements in. Laser and high To superconductivity research can be met with this machine.
