| 摘 要： | 由双向进气阀引起的直流流动是脉管制冷机在高温区如80K温度不稳定的根本原因.本文理论和实验研究了通过改变回热器流阻进行直流抑制的可行性.结果表明:适当增加回热器流阻,可以有效抑制直流,进一步改善双向进气脉管制冷机性能,实现在较高温区长时间稳定工作,为解决其存在的高温区性能不稳定提供了新的途径.

| Abstract: | The DC flow induced by the double-inlet in a pulse tube cooler is the main reason of temperature instability. The possibility of utilizing regenerator flow resistance to suppress DC flow is theoretically and experimentally investigated. Both results show that with a proper larger regenerator flow resistance, DC flow could be suppressed to a smaller extent. Then a long-time operation of the cooler with a stable temperature output at 80K temperature region could be carried out. |
