摘要
本文描述了以新型磁性蓄冷材料Er_3Ni为二级蓄冷器填料的双级G—M型制冷机在不同转速下的实验结果及和常规材料Pb为二级蓄冷器填料的双级G一M型制冷机的性能比较。该制冷机的二级最低温度为;60rpm时,6.1K;48rpm时,5.4K;36rpm时,最低温度出现了4.28K的峰值.
In this paper,the experimental results obtained from a two-stage G-M refrigerator with magnetic material as a 2nd regenerator matrix instead of Pb matrix are described.The purpose of this study is to improve the refrigeration performance.The refrigerator has reached the lowest temperature of 6.1K at 60rpm,5.4K at 48rpm and 4,28K(peak value) at 36rpm,respectively.
