| 摘要: |
| 设计加工了不同叶片角度的导流叶片形涡流管整流器。搭建了涡流管性能研究实验台。对整流器及其叶片角度对涡流管能量分离性能的影响，整流器对涡流管的长径比的影响进行了实验研究，并将白行设计加工的带有上述整流器的涡流管与ARTX公司生产的同类型涡流管进行了对比实验。实验结果表明：在涡流管末端加装上述整流器后，在冷流率为50％～80％时，涡流管的单位制冷量比不装整流器的涡流管提高了12％～44％；在实验研究的角度范围内，冷流率小于70％时，整流器叶片角度越大，制冷效果越好；加装整流器后，将涡流管的长径比由10．8降低到4．6，并且保持制冷效应不变；上述带整流器的涡流管在冷流率大于60％时，其制冷效应好于ARTX公司的同类型涡流管。 |

| Effect of the Rectify on the Energy Separation Performance of the Vortex Tube |
|
|
|
| Abstract: |
| Rectifies of various guide vane angles which is used in vortex tube had been designed and fabricated.A reliable test rig had been designed and constructed to investigate the effect of rectify and its vane angle on the energy separation performance,rectify on the length/diameter ratio of a vortex tube system.The comparison experiments have been carried out using the aforesaid vortex tube and the tube of the same type made in ARTX Company.The results show that the unit refrigeration of the vortex tube with the rectify is increased by 12%~44% than that without rectify when the cold mass flow ratio is 50%~80%,the bigger angle of the rectify the better refrigeration effect is got with the cold mass flow ratio less than 70%,the length/diameter ratio of the vortex tube with rectify is decreased 6.4 times without impairing the refrigeration,and the aforesaid vortex tube gets better refrigeration effect than that made in ARTX company when the cold mass flow ratio is bigger than 60%.. |
