摘要
该文提出了一种新的不带气库的脉管制冷机──双阀双小孔型脉管制冷机,对这种制冷机的性能进行了实验研究,并将它与基本脉管制冷机及小孔气库型脉管制冷机作了比较.在同样条件下采用小孔气库型结构得到最低温度572K,采用双阀双小孔结构得到最低温度55K.这种脉管制冷机与小孔气库型脉管制冷机性能相当,但它省去了气库,具有结构简单、体积小的优点.
A novel pulse tube phase shifter-two valves and two orifices one is presented in this paper.The experiment investigation a refrigerator with this new construction phase shifter is made and the test restlt is given.The minimum temperature of 55K has been made with the new design,and 57.2K has been obtained with orifice-reservoir pulse tube at the same conditions.The performance of the new type refrigerator is equivalent to the orifice-reservior one but the new type is simple in construction and small in she,so it is competitive.
