Carry air conditioning through the cold air duct circulation and cool down the switch board cabinet body, supplementary dispel the heat to the switch board cabinet body is internal.

The first step is as follows: the cooling heat dissipation structure 2 blows cold air from the periphery to the inside of the cabinet body 1 of the power distribution cabinet for heat dissipation; the cold air circulation structure 4 cools the shell of the cabinet body 1 of the power distribution cabinet to assist internal heat dissipation;

the second step is that: the blowing structure 23 blows out cold air in the cold air interval 326 to impact the inside of the cabinet body 1 of the power distribution cabinet corresponding to the frame structure 325, the blowing structure 23 swings to blow air, and the frame structure 325 blows out swing air to sweep the air on the internal parts of the cabinet body 1 of the power distribution cabinet; and performing cold air temperature reduction treatment.

The third step: 23 rotatory circumference of structure of blowing is bloied, frame construction 325 blows off air conditioning and forms the cooling whirlwind in the inside formation of the switch board cabinet body 1, and the cooling whirlwind is mixd and is cooled off the heat dissipation to the switch board cabinet body 1 inside, makes the interior electric elements of switch board can be fine cool down, avoids causing the damage.

The foregoing is a preferred embodiment of the present invention, and it will be apparent to those skilled in the art that modifications and finishes can be made without departing from the principles of the invention, and such modifications and finishes are also considered to be within the scope of the invention.
