摘要
针对双向进气结构脉管制冷机稳定性,本文开展了研究。理论分析了脉管制冷机温度不稳定产生的原因,在此基础上考察了制冷功率、填料组成和工质组分等因素对脉管制冷机稳定特性的影响,进一步揭示了不稳定现象形成的机理,对于今后开展脉管制冷机的实用化研究具有一定的参考价值。
Temperature stability characteristic of a double-inlet pulse tube cooler is studied. The reason caused by the temperature instability is theoretically analyzed. The influences of the cooling power, the regenerator matrix arrangement and the working fluid composition on the temperature stability characteristic are analyzed and the creation mechanism of the temperature instability is revealedi. Results are helpful to the application of the pulse tube cooler.
