西德LEYBOLD—HERAEUS公司研制的KRYOGEN R—210型制冷机是一种多用途的两级低温制冷机。这种制冷机是根据吉福特—麦克马洪(Gifford—McMahon)的封闭氦气循环原理来工作的。它已商品化。 制冷机的温度及冷量如下:第一级:温度80K,冷量12瓦(50周/秒)冷量15瓦(60周/秒)
KRYOGEN R-210 refrigerator developed by West Germany LEYBOLD-HERAEUS is a multi-purpose two-stage cryogenic refrigerator. The chiller works on the principle of closed helium circulation by Gifford-McMahon. It has been commercialized. The temperature and cooling capacity of the refrigerator are as follows: First stage: temperature 80K, cooling capacity 12W (50 cycles / second) cooling capacity 15W (60 cycles / second)
