中文摘要：

基于一台单级直线型脉冲管制冷机,研究分析了热端温度变化对制冷机性能的影响关系。建立了一维数值模型,分析了高频脉冲管制冷机内部相关热力学参数随热端温度变化的关系,从而揭示了热端温度变化影响整机性能的作用机理。最后通过实验数据和模拟值的比较研究,验证了模型的准确性。

英文摘要：

Hot end temperature impact of a single-stage inline pulse tube cryocooler was studied. One- dimensional numerical model was set up to analyze the thermodynamic parameters of the pulse tube cryo- cooler, which can explain the reason for deterioration of cryocooler performance when increasing the hot end temperature. Experimental results show a good agreement between experimental data and theoretical simula- tion values.
