Background technique

Electrical equipment refers to the collective designation of generators, transformers, power lines, and breakers in the power system. Since electrical equipment is usually loaded with a large amount of charge and generally has a high heating efficiency, the heat dissipation efficiency of electrical equipment has also become one of the important indicators for maintaining the safe operation of equipment. In the prior art, in order to improve the heat dissipation efficiency of electrical equipment, we usually place the equipment inside the heat dissipation cabinet, and the heat dissipation cabinet is provided with a ventilation system, which can well remove the heat emitted by the electrical equipment. Nowadays, common cooling cabinets on the market use air cooling to dissipate heat. Therefore, when the ambient temperature is high, the temperature of the air discharged into the cooling cabinet is also high, so the cooling efficiency is average. In addition, the existing heat dissipation cabinet has a single air inlet, so the air entering the cabinet is relatively concentrated, and the cooling gas cannot be evenly distributed in the cabinet, so the heat dissipation efficiency is also restrained to a certain extent.
