[0002] A distribution cabinet is a device for low-voltage power distribution that is assembled in a closed or semi-closed metal cabinet or on a screen according to electrical wiring requirements, with switchgear, measuring instruments, protective electrical appliances and auxiliary equipment.

[0003] At present, a large number of electronic components are installed in the power distribution cabinet. When the electronic components are running, in addition to the useful work output, a lot of electrical energy is converted into heat energy, which increases the temperature of the electronic components. Electronic components are easily damaged if the temperature is too high. Most of the existing power distribution cabinets use air cooling for heat dissipation. Filters need to be set during heat dissipation. However, dust and cotton-like impurities are attached to the outer surface of the filter, which can easily cause the filter to be blocked, resulting in a low air circulation rate and affecting the heat dissipation effect.

[0004] In view of this, the present utility model is proposed. Utility Model Content
