Abstract

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 rings, the airflow forms annular airflow through the rotational flow rings before entering the pipeline, the problem that the high-pressure airflow and the separated cold and hot airflow interfere with each other is solved, and the refrigeration efficiency of the assembly type refrigeration vortex tube is improved.

Description

technical field [0001] The invention belongs to the technical field of temperature control, and in particular relates to an assembled refrigeration vortex tube. Background technique [0002] The vortex tube is a mechanical device, which is mainly used to divide the high-pressure gas into cold flow and hot flow, and flow out from both ends respectively. It can be applied to cooling electronic equipment or cooling parts that need to be cooled rapidly. It mainly introduces the external high-pressure gas into the vortex tube, and accelerates the expansion of the gas through the vortex tube, and then makes the air flow form a high-speed vortex in the vortex tube, and through the pressure difference between the cold and hot end output tubes at both ends, the accelerated expansion is achieved. The air flow forms backflow gas, which is then separated and transformed into cold and hot air, and then the cold and hot air are separated and output through the output pipes at both ends fo...
