Description

Electric box cooling cover

The present invention relates to a radiator, in particular to a heat dissipation cover of an electric box.

Electric power companies and telecommunications operators provide power and communication services for various businesses and households, and there are many electrical boxes (or substations) in the intermediate process and path for power distribution or communication data transmission. Since the inside of the electric box may generate heat due to power or communication data transmission, various heat dissipation mechanisms are required to solve the heat dissipation problem. However, the operator cooperates with the electric power company or the telecommunication operator to provide the heat dissipation cover of the electric box. Of course, the necessary condition of the heat dissipation cover must be able to remove the heat inside the electric box, and at the same time, it must prevent rainwater from pouring into the electric box when it rains. Corrosion or short circuit of parts caused by the electric box. Therefore, the applicant in this case has invented and applied for a Taiwan invention application No. 108147894 "radiator" (application on the same day of the invention, application number 108217278) to solve the problem of heat dissipation and waterproof splashing. The prior art is roughly as shown in the sixth figure, the electrical box heat dissipation cover includes a cover body (3), wherein the cover body (3) includes a top wall (31) and respectively extends downward from the top wall (31). Front side wall (not shown), rear side wall (33), left side wall (34) and right side wall (35), the front, rear, left and right side walls frame an opening (36), and the top wall (31 ) is provided with a plurality of exhaust holes (37) communicating with the opening (36), the cover (3) is used to cover the top of an electrical box (not shown), and the opening (36) is used to provide the The heat is exported. According to the prior art, the inside of the cover (3) is respectively extended from the inner side of the top wall (31) with two first guide plates (391) formed from the inner to the left and the right side wall from high to low. A second guide plate (392) spaced in parallel is arranged below the guide plate (391); and each first guide plate (391) forms an upper flap (399) at the outer end, and each first guide plate (391) forms an upper fold (399) at the outer end. The guide plate (391) is provided with a plurality of sink holes (398) near the upper flap (399), and a ventilation gap is formed between the first guide plate (391) and the second guide plate (392) (D), the ventilation distance (D) is communicated with the plurality of exhaust holes (37); the outer ends of the second guide plates (392) are folded down to form an L-shaped piece (393), the L-shaped piece ( The bottom cross piece (394) of 393) is provided with a plurality of perforations (395); the inner ends of the first guide plates (391) and the second guide plates (392) are connected to a side plate (396), and the side plate ( 396) is provided with a ventilation hole (397). When the hot air of the electric box escapes from the top of the electric box to the opening (36), from the ventilation holes (397) to the ventilation distances (D), and then the hot air circulates through the upper flaps (399) The gap at the rear end, or through the downholes (398), enters the space above the first guide plates (391), and escapes through the plurality of exhaust holes (37) on the top wall (31). Although the prior art is also provided with the aforementioned first guide plates (391), second guide plates (392), etc. in order to prevent rainwater from entering the interior of the electrical box, and guide the rainwater to the L The plurality of perforations (395) provided on the bottom horizontal sheet (394) of the shaped sheet (393) flow out. However, it is found in the prior art that, since each first guide plate (391) forms an upper flap (399) at the outer end, the upper flap (399) may slightly block the rain even though the rain still remains. It is possible to run down from the sinkhole (398), but there is still room for improvement. And the inner ends of the first guide plates (391) and the second guide plates (392) are connected to a side plate (396), the side plate (396) is provided with the ventilation hole (397), when the rain is too large , it is still possible to directly punch into the ventilation hole (397) from the ventilation distance (D) and enter the interior of the electrical box.

Although only part of the prior art has yet to be improved, based on the concept of continuous research and development and the spirit of excellence, the inventors of the present invention are still willing to make continuous efforts to seek innovations with better effects. For this purpose, a heat dissipation cover for an electrical box is designed, which includes a cover body, wherein the cover body includes a top wall and front, rear, left and right side walls extending downward from the top wall, respectively. The front, rear, left and right side wall frames An opening is formed around it, and the top wall is provided with a plurality of exhaust holes communicating with the opening. The cover body is used to cover the top of an electric box, and the opening is used to provide the hot air generated by the electric box. The outlet is characterized in that the cover The inside of the body is respectively extended from the inner side of the top wall with two first guide plates formed from high to low from the inside to the left and right side walls, and a second guide plate with a parallel interval is arranged below the first guide plates ; And each first guide plate forms a lower fold at the outer end, and the bottom edge of the lower fold and each second guide plate form a first ventilation distance, the first ventilation distance and the plurality of exhausts The holes communicate with each other; the outer end of each second guide plate is folded downward to form an L-shaped piece, and the bottom transverse piece of the L-shaped piece is provided with a plurality of perforations; the inner end of each second guide plate is folded upward to form a blocking piece, The top edge of the blocking piece and the first guide piece form a second ventilation distance, and the second ventilation distance is communicated with the first ventilation distance; and the top wall extends downward with two spaced third guide plates, each of which is The third guide plate and the inner edge of the second guide plate respectively form a third air gap, and the third air gap is communicated with the opening and the second air gap. By forming a folded sheet at the outer end of the first guide plate, it is convenient for rainwater to flow to the second guide plate and even the plurality of perforations described in the bottom cross piece of the L-shaped sheet, and at the same time, use the various perforations. The inner end of the second guide plate is folded upward to form a blocking piece, so that even if the rain is heavy, an additional blocking piece can be obtained. At the same time, the top wall extends downward with two spaced apart third guide plates, each of the third guide plates and the inner edge of the second guide plate respectively form a third ventilation distance, and the third ventilation distance and the The opening and the second ventilation distance are communicated, so the flow of hot air is still not hindered.

The structure, features and embodiments of the present invention will be described below with the aid of the drawings, so as to enable your examiners to have a further understanding of the present invention.
