摘　　要：脉冲管制冷机是一种典型的调相型制冷机,工质的相位差分布情况对制冷机的运行状态具有决定性的影响。为了从热力学角度探究相位差对制冷过程的影响,基于热力学非对称理论,建立了关于蓄冷器内部工质微元的热力学分析模型。重点对比了实际情况和理想情况下,蓄冷器冷端处工质最佳相位差的区别。基于微元循环模型分析了实际情况下微元最佳相位差偏离0度的原因,并阐述了蓄冷器内工质与填料换热对最佳相位差的影响机理。The pulse tube cryocooler(PTC) is an identical phasing cryocooler, the distribution of phase angle has a deep influence on the PTC’s performance. In order to analyze the influence of phase angle on thermodynamic cycles, a gas parcel model of the regenerator is built base on the thermodynamic nonsymmetric effect theory. The difference between the optimal phase angle of the ideal condition and the actual condition in regenerator are discussed. The reason that the optimal phase angle deviates from the 0 degrees at actual condition is analyzed on details, and the mechanism of the influence of heat transfer on the optimal phase angle is shown.
