摘要
首先简要介绍了目前的一些对于脉管制冷机的理论分析方法以及各种损失分析计算,接着针对某尺寸的四阀型脉管制冷机,考虑到不同厚度的脉管对其的影响,结合两种厚度的脉管进行热力计算和损失分析,分析结果表明,四阀型脉管制冷机的主要损失在于阀门处,进一步降低阀门损失将是提高制冷机性能的主要手段。
Some theoretical analysis methods for pulse tube cryocooler were firstly introduced in this essay, then thermodynamic calculation used in this essay was described. The thermodynamic result of the thermodynamic calculation on a four valve pulse tube cryocooler with fixed size was shown. We can conclude from the the analysis of the results ： valve loss is the main loss of the four valve pulse tube cryocooler, thin - thickness of pulse tube will be the main way to improve the performance of the cryo- cooler.
