The air outlet part includes a converging chamber and a trumpet-shaped air outlet part connected to each other. The converging chamber covers the hot air outlet.

The moisture-proof device in the electrical cabinet provided by the present invention mainly utilizes the combination of the PTC heating element and the micro-motor fan to blow hot air to the inside of the cabinet to dry the water droplets and moisture adhered to the inside of the electrical cabinet due to the weather. Compared with the existing moisture-proof device, the moisture-proof device in this application uses gas, which is more uniform and soft, and has a better drying effect. The fence mesh at the air supply port can prevent part of the dust in the installation box from entering the inside of the cabinet, thus affecting the functions of the internal components of the cabinet. The hot air outlet is equipped with a fence net, which also has the effect of filtering dust and can also disperse the hot air evenly. The installation box is arranged on the outside of the electrical cabinet and does not occupy the space inside the cabinet. Setting the cover and the air supply branch pipe can not only concentrate the wind force, but also effectively send the wind force to different locations, and the moisture-proof effect is better.
