摘　　要：涡流管作为一种无运动部件的制冷制热装置,结构简单、制冷较快且无污染。采用多个涡流管(编号为1、2、3、4号),通过调节其热端调节阀来改变其冷热端出气量,测定其两端各自的温度及流量,计算出其冷量。并采用冷量较大的涡流管(2号和4号)来进行降温实验,得出涡流管的具体降温数据。以此为基础,在实验箱内采用2号和4号涡流管送冷风方式,来测得不同情况下的实验箱内不同位置的温度,从而得出双涡流管在同向近距离吹风为较好的降温方式,可将实验箱内温度将至27℃左右;且降温效果跟压缩气体压力存在一定关系,在压缩气源0.5MPa时效果较好;实验箱内在靠近气源处温度较低,为26℃左右。As a refrigeration and heating device without moving parts,vortex tube has simple structure,rapid refrigeration and no pollution.In this paper,a number of vortex tubes(No.1,No.2,No.3 and No.4)will be used,and the air output at the cold and hot ends will be changed by adjusting the regulating valves at their hot ends,and the respective temperatures and flow rates at both ends will be measured to calculate their cooling capacity.The vortex tubes(No.2 and No.4)with large cooling capacity are used to carry out the cooling experiment,and the specific cooling data of the vortex tubes are obtained.On this basis,the temperature of different positions in the experimental box was measured by using the methods of No.2 and No.4 vortex tubes to send cold air in the experimental box,and it was concluded that the double vortex tubes blowing air in the same direction at short distance was a better cooling method,which could bring the temperature in the experimental box to about 27℃.And the cooling effect has a certain relationship with the pressure of compressed gas,and the effect is better when the compressed gas source is 0.5MPa;The temperature in the experimental box near the air source is low,about 26℃.
