Problems solved by technology

Due to the blocking of the rain cover, it is difficult for the rainwater blowing horizontally with the wind to enter the cabinet; however, it is also difficult for the airflow blowing horizontally to enter the cabinet, which limits the heat dissipation performance of the power cabinet to a large extent

Abstract

The invention relates to a rain-proof electric cabinet comprising a housing. Guiding holes are formed in the bottom of the housing. Driving fans are installed on the top of a top plate of the housing; sectors of the driving fans are parallel to the top plate; and driving shafts of the driving fans extend into the housing. In the housing, driving shafts are installed by matching the driving shafts and extend vertically and downwardly. Air distributing wheels are arranged on the driving shafts at equal intervals; air guiding shells cover all air distributing wheels; and air-supply pipes of the air guiding shells extend into the side wall of the housing and discharge pipes of the air guiding shells point at the inner cavity of the housing directly. All air guiding shells are communicated by guiding pipes; and the lower ends of the guiding pipes extend out of the bottom of the housing. According to the electric cabinet, rainwater entrance is prevented effectively while the good cooling performance is guaranteed; and usage security of the electric cabinet is improved.

Description

technical field [0001] The invention relates to a power device, in particular to a power cabinet. Background technique [0002] The power cabinet is a kind of basic power equipment, and a large number of electrical components are assembled inside; therefore, the waterproofness of the power cabinet is very important; especially the outdoor power cabinet, because it needs to experience rainy weather for many years, its waterproof requirements are higher than those of indoor power cabinets. The cabinet is much taller; the current outdoor power cabinet, although it needs to consider waterproof, still needs to dissipate heat. Therefore, there are still cooling openings on the side wall of the cabinet. Generally, for waterproofing, the cooling openings are made in the form of strip shutters. A rainproof cover is arranged above each strip-shaped heat dissipation port. Due to the blocking of the rain cover, it is difficult for the rainwater blown horizontally by the wind to enter t...
