The utility model has a reasonable structural design, which can effectively prevent dust from entering the cabinet while ensuring good heat dissipation, and the dust screen is easy to disassemble and clean, thereby extending the service life.

[0004] With regard to the above-mentioned related technologies, the rotation of the cooling fan on the top allows air to enter the cabinet from the air inlet windows on both sides of the cabinet and be discharged from the top of the cabinet, thereby achieving air circulation and taking away the high-temperature air in the cabinet. However, during the use of the low-voltage switch cabinet, since many electrical components will be installed inside, the electrical components will be connected through cables, resulting in a relatively messy interior of the low-voltage switch cabinet, which will affect the air flow around the electrical components, causing the temperature to rise and affecting normal operation.
