摘要
针对高频脉冲管制冷机实际应用中引入的连管进行了研究,实验结果表明加长连管导致性能下降的关键因素在于流动阻力损失,在选取时应尽量减少连管长度,在长度无法改变的情况下,可以选用较大直径的连管以减少流动损失,另外运行在略低的频率也会对制冷性能下降有所改善。
Bsaed on an optimized pulse tube cryocooler (PTC), the influence of transfer line between compressor and cooler finger was investigated. The expermental reasearch shows that transfer line will deteriorate the PTC performance due to flow friction. Less length, bigger diameter and lower operation frequency will gain considerable improvement.
