The cold and hot air are separated by the vortex tube 3, and the cold air is allowed to enter the interior of the shell 11 to achieve a cooling effect.

[0032] In this way, cold air is provided to the shell 11 through the vortex tube 3 and the intake pump 4, and the heat exchange between the shell 11 and the outside is reduced by providing the insulation board 5, so that the inside of the shell 11 is maintained at a relatively low temperature to protect the normal operation of the circuit components.

[0033] In some feasible ways, the mounting back plate 12 is a mounting plate for mounting components. The mounting back plate 12 is usually provided with mounting rails, etc., for easy installation of components. The mounting back plate 12 is provided with through holes, which are arranged according to the positions of the mounting rails, so as to facilitate cooling of the components. The refrigeration pipe 2 includes a main pipe and a branch pipe. The main pipe is connected to the vortex tube 3, and the branch pipe is connected to the through hole of the mounting back plate 12. The vortex tube 3 is installed at the upper end of the refrigeration pipe 2. The vortex tube 3 is a prior art and will not be described here. According to the specifications of the cabinet 1 and the cooling requirements, multiple groups of vortex tubes 3 and refrigeration tubes 2 are installed. By setting the vortex tube 3 for cooling, the need for a specific refrigerant in the refrigeration process is reduced, and cooling is completed by inhaling air. At the same time, the vortex tube 3 has a simple structure, which reduces the difficulty of maintenance and the production cost.

[0034] The exhaust pipe 31 is used to exhaust gas after cold air enters. The exhaust pipe 31 is installed with a one-way valve to reduce the possibility of external hot air entering the cabinet 1 through the exhaust pipe 31.

[0037] Furthermore, the threaded cap 21 is fastened to the mounting back plate 12 , and the threaded cap 21 is made of insulating material.

[0038] It should be understood that the threaded cap 21 is fastened to the mounting back plate 12 to facilitate timely resealing after the components are removed, and the threaded cap 21 is made of insulating material to reduce the possibility of electric shock.

[0039] In some feasible embodiments, the threaded cap 21 is in the shape of a bolt, and an annular groove is formed in the threaded cap 21 .
