| 摘 要： | 脉冲管制冷机冷头朝上布置可以使制冷机与超导器件的耦合更方便 ,但对G -M型脉冲管制冷机 ,重力会对这种布置方式产生不利影响。对双向进气型脉冲管制冷机 ,直流和耦合传热会共同影响脉冲管制冷机的性能。介绍了液氮温区G -M型同轴脉冲管制冷机的实验结果 ,主要研究了蓄冷器温度分布和重力对脉冲管制冷机性能的影响

| Abstract: | Placing the cold head at the upper position can facilitate the connection of the with the super_conducting devices.However,for G-M type PTR,the gravity has the disadvantage influence on this situation.For double inlet PTR,DC flow and coupling heat transfer affect the performance of the refrigerator together.The experimental results of G-M type co-axial PTR at the temperature range of liquid nitrogen with the focus on the temperature profile of the regenerator are presented and the effect of the gravity on the perfomance of the PTR is described. |
