Assembled refrigeration vortex tube

The invention discloses an assembled refrigeration vortex tube, which belongs to the technical field of temperature control, and comprises a vortex cavity connected with a cold end output tube and a spiral generator, and a hot end output tube is arranged at one end of the spiral generator deviating from the cold end output tube; the swirl flow generator comprises a swirl flow ring, an annular gap is reserved between the swirl flow ring and the inner wall of the second flow channel, and at least one notch for communicating the inside and the outside is formed in the periphery of the swirl flow ring in the tangential direction of the inner circumference of the swirl flow ring. And airflow introduced by the inlet connector forms annular airflow along the periphery of the rotational flow ring, and the annular airflow enters the rotational flow ring through the notch. According to the assembly type refrigeration vortex tube, high-pressure airflow and cold and hot airflow are divided through the rotational flow rin
