Problems solved by technology

[0004] These patents are mainly aimed at the improvement of the performance of the vortex tube, and do not pay attention to the operation of the vortex tube. If the user needs heating after a period of time in a place where cooling is required, then it is necessary to change the position of the vortex tube or install it in the vortex tube. Add switching valves in the external pipeline to meet the needs, which not only increases the complexity of the operation, is not conducive to the operation of ordinary users, but also increases the overall cost of the equipment

Abstract

The invention discloses a vortex tube with an axial cold and heat switching mechanism. The vortex tube comprises a vortex chamber. Two sides of the vortex chamber are respectively provided with an air outlet, a first working cavity and a second working cavity which are communicated with each other are arranged in the vortex chamber, cavity walls of the two working cavities are respectively provided with an air inlet, and two vortex separators corresponding to respective air inlets are arranged in the two working cavities respectively. Each vortex separator is provided with a fluid channel and a vortex spraying channel perpendicular to the fluid channel. A sealing element for axially sliding along the vortex chamber to be used for selectively opening the air inlets is arranged outside the vortex chamber, and an adjusting mechanism in linkage with the sealing element so as to adjust flowing directions of cold and hot fluids in the vortex chamber is arranged in the vortex chamber. The adjusting mechanism for adjusting the flowing directions of the cold and hot fluids in the vortex chamber is arranged in the vortex chamber, the flowing directions of the cold and hot fluids in the vortex tube can be easily exchanged according to actual requirements in practical use, a whole device does not need dismantling, and practicality is good.

Description

technical field [0001] The invention belongs to the refrigeration field, and in particular relates to a vortex tube with an axial cold-heat switching mechanism and a heat exchange system with the vortex tube. Background technique [0002] Social development, industrial progress, in order to obtain high-performance industrial parts, improving machining accuracy is an important issue in industrial production. A large amount of heat will be generated during the processing of the workpiece, which is not conducive to improving the processing accuracy of the workpiece. In order to reduce the impact caused by this heating, people have come up with various ways to cool the workpiece when it is processed. For example, when lathes process cutting parts, some parts need to use coolant to cool down, so as to reduce the impact of chip heating on the accuracy of parts. However, when the coolant is heated and evaporates, it will bring some harmful substances into the air, which will caus...
