The embodiment of the utility model provides an electrical cabinet, refer to fig. 1 to 9, this electrical cabinet includes the cabinet body 10, supporting seat 20, guard shield 30 and fan 40, is equipped with in the cabinet body 10 and holds chamber 10a, and the diapire of the cabinet body 10 is equipped with first wind gap 10b, and the lateral wall of the cabinet body 10 is equipped with second wind gap 10c, holds chamber 10a and communicates first wind gap 10b and second wind gap 10c; the cabinet body 10 is supported on the supporting seat 20; the shield 30 is covered on the second tuyere 10c from the outer side and forms an airflow channel 30b, the shield 30 is provided with a third tuyere 30a, the airflow channel 30b is communicated with the second tuyere 10c and the third tuyere 30a, and the position of the third tuyere 30a is lower than that of the second tuyere 10c; the accommodating cavity 10a and/or the airflow channel 30b are provided with a fan 40.

In the accommodation chamber 10a are arranged electronic components to be mounted and associated wiring for electrically connecting the electronic components. The cabinet 10 protects the electronic components in the accommodating cavity 10a.

In the working process of the fan 40, the driving air flow directionally flows among the first air port 10b, the second air port 10c and the third air port 30a, and meanwhile, the first air port 10b and the third air port 30a are communicated with the outside, so that the outside air flow can realize convection with the air flow in the accommodating cavity 10a, heat generated by the electronic components in the accommodating cavity 10a is taken away, and the cooling and heat dissipation effects are achieved.

It can be understood that the cabinet body 10 is formed by welding a plurality of sheet metal parts, and the dustproof and waterproof performance of the joint positions between the sheet metal parts is improved by adopting a welding mode.

It is to be understood that the specific type of fan 40 is not limited, such as axial flow fan 40, crossflow fan 40, or the like.

The bottom wall of the electrical cabinet is spaced from the ground surface by the support base 20, so that the air flow can enter or exit the accommodating cavity 10a from the first air opening 10 b.

On one hand, in the process of flushing the electrical cabinet, when the side wall and the top wall of the electrical cabinet are flushed, water flows down along the side wall of the electrical cabinet under the action of gravity and cannot flow through the bottom wall of the electrical cabinet, so that the water cannot directly enter the accommodating cavity 10a through the first air opening 10b; when the ground below the electrical cabinet is washed, the distance between the bottom wall of the electrical cabinet and the ground surface is small, and water flow is difficult to directly wash the bottom wall of the electrical cabinet, so that the probability that water flow directly enters the accommodating cavity 10a through the first air opening 10b is reduced. On the other hand, even if a part of water flow enters the first air opening 10b due to sputtering, since the first air opening 10b is located at the bottom wall of the cabinet 10, the water liquid entering the accommodating cavity 10a can be discharged through the first air opening 10b, and the probability of water flow accumulation in the accommodating cavity 10a is reduced.

The second air opening 10c is arranged on the side wall of the cabinet body 10, on one hand, the second air opening 10c is far away from the first air opening 10b, the flowing distance of the air flow between the first air opening 10b and the second air opening 10c is increased, more heat in the accommodating cavity 10a is taken away by the air flow, and the heat dissipation and cooling effects are improved; on the other hand, the situation that the second tuyere 10c is arranged on the top wall, so that dust naturally settles through the second tuyere 10c into the accommodating chamber 10a is avoided.
