Utilize heat dissipation mechanism 2 to make the air in the cabinet body 1 circulate, utilize cooling body 3 to cool down the air of circulation simultaneously to make the temperature in the cabinet body 1 descend, the difficult exchange that produces of the inside and outside air of the in-process cabinet body 1 of cooling, thereby make the dust can not get into in the cabinet body 1, make electrical components's heat dissipation can not receive the influence of dust.

As shown in fig. 2, the cooling mechanism 3 includes a cooling pipe 31 with both ends closed, a water inlet pipe 32 for supplying water into the cooling pipe 31, and a water outlet pipe 33 for discharging water from the cooling pipe 31, the water inlet pipe 32 and the water outlet pipe 33 are respectively connected to both end surfaces of the cooling pipe 31 by using pipe joints, the cooling pipe 31 is horizontally disposed, and the connection position of the water inlet pipe 32 and the cooling pipe 31 is lower than the connection position of the water outlet pipe 33 and the cooling pipe 31.

The air in the radiating pipe 21 is cooled by the water continuously flowing in the cooling pipe 31, thereby indirectly adjusting the temperature in the cabinet 1.

As shown in fig. 3, since the water in the cooling pipe 31 contacts only the outer wall of the radiating pipe 21 during cooling, the contact area therebetween is small, and the cooling rate is low. Therefore, the inner wall of the heat dissipation pipe 21 in the cooling pipe 31 is integrally formed with a plurality of heat dissipation plates 34, the axis of the heat dissipation pipe 21 passes through the heat dissipation plates 34, two side walls of the heat dissipation plates 34 far away from each other are connected with the heat dissipation pipe 21 and are penetrated with heat dissipation holes 341, the heat dissipation holes 341 penetrate through the outer wall of the heat dissipation pipe 21, and a gap is left between two side walls of the heat dissipation plate 34 far away from each other, which are not provided with the heat dissipation holes 341.

The air deflector 42 is used for guiding the flowing direction of the air, so that the air passing through the air deflector 42 moves towards the two sides of the gravity center of the cabinet body 1, the air at each part of the cabinet body 1 is easy to flow, and the cooling effect of the temperature in the cabinet body 1 is better.

As shown in fig. 1, since the opening of the air guiding hole 41 is large, when an electrical component is installed in the cabinet 1, the electrical component is liable to fall into the air guiding hole 41, so that the upper end of the air guiding block 4 can be connected with the screen 43 by using a bolt, and the screen 43 closes the air guiding hole 41. The screen 43 is used for blocking the sundries falling into the air guide hole 41, so that the electric elements cannot be taken out due to falling into the air guide hole 41 when being installed, and the cabinet body 1 is more convenient to use.

As shown in fig. 1, when air circulates in the cabinet 1 through the heat dissipation mechanism 2, the air easily flows into the cabinet 1 from a gap between the cabinet door 11 and the cabinet 1, and at this time, the air flowing into the cabinet 1 brings in part of dust, thereby affecting heat dissipation of electrical components.
