摘　　要：利用涡流管部分轴线温度测量实验装置,考虑到进气压力和涡流室结构对涡流管能量分离过程的影响,针对不同进气压力和不同涡流室结构的涡流管部分轴线温度分布进行了实验研究。根据实测结果,得到了进气压力及涡流室几何结构对涡流管部分轴线温度分布的影响曲线。在此基础上,根据实验结果并结合热力学原理对涡流管制冷的物理行为作了分析。结果表明:涡流导致涡流室中心区域气流膨胀是涡流管产生制冷效应的一个重要原因。By utilizing an apparatus for measuring axial temperature of vortex tube, with the influence of inlet press and structure of vortex chamber on energy separation process considered, experimental studies on axial temperature for different inlet press and vortex chamber structures were made. Curves of axial temperature affected by different inlet press and geometrical structures of vortex chamber were drawn according to the measuring results. Further, physical behavior of refrigeration in vortex tube was analyzed according to the experimental results as well as thermodynamic principle. Results show that gas expansion in central region of vortex chamber caused by swirling flow is an important reason for the refrigerating effect of vortex tube.
