Description

Technical Field

[0001] The utility model relates to the technical field of vortex tubes, in particular to a downstream vortex tube structure. Background Art

[0002] A vortex tube is an energy separation device with a simple structure and no moving parts, but it can separate the working gas into two gases, cold and hot, under the condition of a certain pressure difference between the inlet and outlet. Vortex tubes are divided into co-current type and counter-current type. In the co-current type, the cold and hot gas outlets are located on the same side of the vortex tube, while in the counter-current type, the cold and hot gas outlets are located on opposite sides of the vortex tube.

[0003] The overall length of the existing downstream vortex tube's outlet pipe is usually fixed, which means that the length of the gas flow path cannot be changed, and thus the time it takes for the cold and hot gases to absorb or release heat in the pipe cannot be changed. This limits the vortex tube's ability to regulate the gas temperature to a certain extent, making it difficult to adjust the final exhaust temperature. Therefore, it is necessary to develop a downstream vortex tube structure. Utility Model Content
