| 摘 要： | 开展了单级G-M型脉管制冷机直流抑制实验研究,考察了直流流动对制冷机性能的影响,估算了不同制冷温度下制冷机循环的需气量,采用两个并联排列、指示箭头方向相反的阀门,称之为并联逆向双阀双向进气结构对直流进行抑制,成功地解决了传统单阀双向进气结构脉管制冷机存在的直流问题。在2kW(RW2)和4kW(CP4000)压缩机驱动时分别获得了18.4K和14.7K的最低制冷温度,对应在30K的制冷量为11.5W和29.5W。 |

| Abstract: | An experimental investigation on DC flow suppression in a single-stage G-M type pulse tube cooler is made. The influence of DC flow induced by the introduction of the double-inlet on the refrigeration performance of the cooler is experimentally examined. Two parallel-placed needle valves with an opposite flow direction called as double-valved configuration, instead of conventional single-valved configuration as the double-inlet is used to reduce the DC flow. With the double-valved configuration, the minimum temperatures of 18.4 K and 14.7 K, and the cooling powers of 11.5 W and 29.5 W are also obtained by RW2 and CP4000, respectively. |
