Description

an electric control cabinet

technical field

The present invention relates to the technical field of electric control cabinets, and more specifically, relates to an electric control cabinet.

Background technique

The electrical components in the electric control cabinet will generate a lot of heat when they work for a long time, so there will be a ventilation structure on the electric control cabinet, but when the electric control cabinet is located in a humid environment, moisture will damage the electrical components due to moisture , the prior art publication number is that the patent literature of CN114243477A provides a kind of automatic sealing device for electric control cabinet, and this device can be in close contact with the heat dissipation holes arranged inside the heat dissipation plate through the blocking column evenly arranged at the right end of the blocking device, so as to ensure that the blocking device has no effect on heat dissipation. The sealing effect of the plate, and the clamping groove provided at the left end of the blocking device can ensure that the connecting device and the blocking device are installed firmly, thereby ensuring the sealing of the blocking device to the heat sink.

Although the device has many beneficial effects, the following problems still exist: after the plugging device contacts with the cooling plate, the inside of the casing forms a completely sealed state, which causes the heat generated by the electrical components to be unable to dissipate, which in turn easily leads to damage to the electrical components . In view of this, we propose an electric control cabinet.
