| 摘 要： | 为了探讨混合工质在脉管制冷机中应用的可行性，选取氦气和氢气混合物作为工质，对一台小孔型脉管制冷机进行了数值模拟分析。结果发现，脉管制冷机的性能与其工质的热物性有很大关系。通过调整混合工质的配比，改变工质的物性，使其在混合工质最佳配比下工作，对于改进制冷机的性能，提高制冷量和制冷系数等都是有益处的。

| Abstract: | In order to investigate the feasibility of using the gas mixture in the pulse tube cryocooler, the mixture of hydrogen and helium was chosen as the working fluid in cryocooler and an orifice pulse tube cryocooler was analyzed by the numerical simulation It is found that the performance of the cryocooler has relation with the thermodynamic properties of the working fluid The optimal percentage of the mixtures can be foundWith this percentage the performance of the cryocooler has been improved.It is useful for increasing the cooling power and COP |
