The vortex refrigeration tube is a device which generates vortex for high-speed airflow by the action of the vortex tube, and then separates cold airflow and hot airflow. When the vortex chamber works, gas which is compressed and cooled to normal temperature enters the nozzle, expands in the nozzle and accelerates to the speed of sound, and the gas is injected into the vortex chamber from the tangential direction to form a free vortex. The greater the rotational angular velocity of the free vortex is near the center, the different angular velocities create friction between the layers of the free vortex. The air flow in the central part has the maximum speed, so that energy is transferred to the air flow with lower angular speed in the outer layer, the air flow in the central part loses energy, so that the speed is reduced, the temperature is reduced, and the air flow is led out from one end through the orifice plate in the center of the vortex tube, so that the cold air flow required by refrigeration is obtained.
