the fan 14 operates to supply air from the bottom of the cabinet body 1 and then to discharge air from the air outlet grooves 13 on the two sides of the air outlet cabinet 12, the air discharged from the two sides of the air outlet cabinet 12 can blow heat of the electric elements in the cabinet body 1, a certain heat dissipation effect is achieved, and meanwhile, the blown air is blown on the heat dissipation pipe 7 subsequently, so that the heat dissipation effect can be further improved, and the electric elements in the middle of the cabinet body 1 can be effectively dissipated;
the left side and the right side of the cabinet body 1 are respectively provided with the air collecting cover 17 in a penetrating way, the tail ends of the two air collecting covers 17 are respectively fixedly provided with the vertical pipes 18, the bottoms of the two vertical pipes 18 are respectively fixedly provided with the transverse air outlet pipe 19, the air blown out from the air outlet cabinet 12 can be exhausted to the outside through the air collecting covers 17, the vertical pipes 18 and the air outlet pipes 19, and the outside air cannot enter the cabinet body 1 under the action of the vertical pipes 18 and the transverse air outlet pipes 19, so that the outside dust and sundries can be prevented from entering the cabinet body 1 through the air outlet pipes 19, and the cleanness of the inside of the cabinet body 1 is ensured;
meanwhile, external rainwater cannot enter the cabinet body 1 through the air outlet pipe 19, so that the effect of preventing rainwater from permeating is achieved, and short circuit of electric elements in the cabinet body 1 is prevented;
a dust filter 16 is arranged below the fan 14, and the dust filter 16 can filter dust entering the fan 14, so that the entering air is kept clean;
the control valve 22 is opened, rainwater in the radiating pipe 7 can be discharged through the sewer pipe 21, the dust filtering net 16 is washed, the cleanness of the dust filtering net 16 is kept, long-time use is facilitated, and blockage is not easy to occur.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
