In normal state, the ventilation hole is connected with the cooling cavity, and the heat dissipated by the module component is passively dissipated through the ventilation hole; when any temperature sensor detects that the temperature in the cooling cavity is higher than the normal temperature of the module component, the controller controls the exhaust fan to open, The exhaust fan exhausts to the exhaust port, so that the outside air is sucked into the heat dissipation chamber from the vent hole, absorbs the heat in the heat dissipation chamber, enters the air passage, and finally is exhausted by the exhaust fan to realize active ventilation and heat dissipation.

Preferably, the inner side of the side plate is provided with a metal filter that completely covers the ventilation hole. The metal filter screen can filter external debris, and the metal filter screen also has certain thermal conductivity.

Preferably, the cabinet door includes a cabinet door frame and a glass plate inside the cabinet door frame. When you don't open the cabinet door, you can directly see various data on the module component panel through the glass plate, realizing visual management.

Preferably, the bottom of the cabinet is provided with supporting feet. The supporting feet can prevent the bottom plate from contacting the ground and prevent water on the ground from entering the DC screen cabinet.

Therefore, the utility model has the beneficial effects of good heat dissipation performance and high temperature alarm function.
