| description | The utility model relates to a nozzle of a vortex tube, which belongs to the field of refrigeration. The utility model is characterized in that a flow channel (1) of a nozzle adopts the geometric symmetry of shafts; the increase of the axial velocity of airflow along the airflow is equal mach grads according to the design method of the equal mach grads along the central axis of the flow channel of the nozzle on air-operation; the loss of air flow is decreased; a front air entering flow channel (2) of the nozzle adopts that the front air entering flow channel (2) of the nozzle and the flow channel (1) of the nozzle are on the same plane; the utility model is designed along a middle line according to the equal air flow speed to keep that the speed on the directional face of a centerline of an air entering flow channel has the same the speed of the inlet velocity of the vortex tube. On one hand, the utility model can improve temperature effect of the refrigeration of the vortex tube, on the other hand, can improve the cold flow rate when the vortex tube reaches the maximize temperature effect of the refrigeration, thereby, the refrigerating capacity per kilowatt and refrigerating coefficient of the vortex tube are improved. |
