The electrical equipment in the distribution cabinet will generate heat during operation. The heat will accumulate in the cabinet, causing the temperature to rise, which may cause equipment failure or even fire and other safety hazards. Therefore, a cooling fan is generally installed in the distribution cabinet to help the distribution cabinet to circulate air and dissipate heat, thereby effectively reducing the temperature inside the distribution cabinet.

[0003] At present, when a distribution cabinet is used, a cooling fan is installed in its inner cavity for heat dissipation. After the cooling fan is installed, a heat dissipation port is generally opened on the distribution cabinet. Some distribution cabinets are set up outdoors for use.
