| 摘 要： | 为了研究惯性管盘绕方式对脉管制冷机性能的影响,揭示不同盘绕结构时惯性管调相能力及制冷机性能变化规律,为实际应用提供必要的实验数据或理论支持,结合湍流因素影响,计算了不同盘绕惯性管的压降损失,分析对调相能力的影响。研究发现,绕圈数越多,压降越大,惯性管调相能力越小。最后,选用了不同盘绕方式的惯性管进行了实验研究,实验结果显示随着惯性管盘绕圈数增加,压缩机效率略微减小,相同冷量下制冷机输入功率显著增大。对惯性管型脉管制冷机盘管方式的实际应用具有重要指导意义。

| Abstract: | To study the influence of inertance tube coiled in the performance of pulse tube refrigerator and reveal the variation of phase shifting of inertance tube and cooling performance of different coiled structure, the pressure drop in the inertance tube coiled was calculated and the turbulence was considered. The pressure drop rose up and the phase angle decreased with increasing coiled numbers. Then, a pulse tube cryocooler with different coiled inertance tubes was tested. With the same cooling power, the compressor efficiency decreased while increasing coiled numbers. The research will be an excellent reference for engineering application of the inertance pulse tube cryocooler. |
