涡流管冷热分离效果影响因素的探究

Exploration of Factors Influencing the Effect of Cold and Ceat Separation in Vortex Tube

涡流管作为一种体积小巧、结构简单的能量分离装置,可用于制冷和制热。为了探究涡流管冷热分离效果的影响因素以及分离效果最佳的涡流管参数,通过大量实验对相关问题进行了研究,研究结果表明涡流管冷端出口为3mm-7mm时,5mm冷端出口分离效果最好;数量为6的收敛型喷嘴比普通型喷嘴分离效果更好;涡流管长径比在12.5-50时,长径比为25时分离效果最好;不同冷端出口直径情况下,进气压力与分离效果成正比。

The vortex tube is used as a compact and simple energy separation device for cooling and heating.In order to investigate the influencing factors of vortex tube cold and heat separation effect and the vortex tube parameters with the best separation effect,this paper has studied the related problems through a large number of experiments,the research results show that the vortex tube cold end outlet is 3mm-7mm,5mm cold end outlet separation effect is the best;the number of 6 convergence type nozzle than the ordinary type nozzle separation effect is better;vortex tube length-diameter ratio in 12.5-50,the length-diameter ratio of 25 when the separation effect is the best;different cold end outlet diameter,the inlet pressure and the separation effect are positive.Inlet pressure is proportional to the separation effect.
