Between the layers of the body box (12) and the upper box (14), an air current suction pedestal (20) having a reverse hopper structure formed by a bottleneck (20a) and four-way inclined surfaces (20b) for forming an updraft, and having a discharge opening (22) is formed. Louver-type ventilation holes (30) are arranged and formed in lower portions of left and right sidewall plates and a rear wall plate of the body box (12). Heating components (34) and a heat sink (36) of the body box (12) are provided. Installation components (38) are spaced apart from each other and arranged so that air current passages (18) for the air current introduced into the louver-type ventilation holes (30) are provided, and thus the heating components (34) or the heat sink (36) is exposed to the air current passages (18). Louver-type ventilation holes (40) are arranged and formed in the four sidewall plates of the upper box (14), so that an external air current is guided toward the louver-type ventilation holes (40) located below the top of the air current suction pedestal (20) to help to discharge a rising hot air current through a discharge opening (22) of the air current suction pedestal (20). The hot air current rising to the upper box (14) is discharged to the outside through the louver-type ventilation holes (40) located above the top of the air current suction pedestal (20). Therefore, the heat generated inside the electric enclosure can be quickly discharged to the outside using an air current.
