In summary, the low-voltage switchgear cabinet built-in inner cooling circulation structure realizes the effective reduction of the temperature inside the cabinet and the improvement of the cooling efficiency through the circulation of the cooling liquid, the rotation of the rotating impeller, the adjustment of the angle of the rotating motor and the rotating impeller, and the cleaning of the dust on the heat dissipation bottom plate. SUMMARY
