Description

Electric box cooling cover

This new creation is about a kind of radiator, especially a kind of heat dissipation cover of electric box.

Electric power companies and communication companies provide power and communication services for various businesses and households, and there are many electric boxes (or substation boxes) in the intermediate process and paths 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. And if a company cooperates with the electric power company or the telecommunications company to provide the heat dissipation cover of the electric box, the necessary conditions for the heat dissipation cover must of course be able to remove the heat inside the electric box, and at the same time, it must prevent rainwater from being poured into the electric box when it rains. The electric box causes parts to rust or short circuit. Therefore, the applicant in this case has invented and applied for a Taiwan Invention Application No. 108147894 "Radiator" (application on the same date as the new model, application number 108217278) to solve the problem of heat dissipation and water splashing. The prior art is roughly as shown in Figure 6, the heat dissipation cover of the electric box includes a cover (3), wherein the cover (3) includes a top wall (31) and extends downward from the top wall (31). The front side wall (not shown in the figure), the rear side wall (33), the left side wall (34) and the right side wall (35). The front, rear, left and right side walls form an opening (36), and the top wall (31) ) Is provided with a plurality of vent holes (37) communicating with the opening (36), the cover (3) is used to cover the top of an electric box (not shown), and the opening (36) is used to provide the electric box generated The heat is exported. According to the prior art, the inside of the cover body (3) is extended from the inner side of the top wall (31) with two first guide plates (391) formed from the inside to the left and the right side walls and from high to low, and the first A second guide plate (392) spaced in parallel is provided under 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) The guide plate (391) is provided with a plurality of sinkholes (398) near the upper flap (399), and a ventilation distance 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 end of each second guide plate (392) is folded down to form an L-shaped piece (393), and the L-shaped piece ( The bottom cross piece (394) of 393) is provided with a plurality of perforations (395); each first guide plate (391) is connected to the inner end of each second guide plate (392) with a side plate (396), and the side plate ( 396) A ventilation hole (397) is provided. After the hot air of the electric box escapes from the top of the electric box to the opening (36), from the vent holes (397) to the ventilation distances (D), then the hot air circulates through the upper flaps (399) The gap at the rear end, or from the sink holes (398), enters the space above the first guide plates (391), and escapes from the plurality of exhaust holes (37) of the top wall (31). Although the prior art also provides the aforementioned first guide plate (391), second guide plate (392), etc., in order to prevent rainwater from entering the electric box, and guide the rainwater to the L The plurality of perforations (395) provided on the bottom cross piece (394) of the shaped piece (393) flow out. However, it is found in the prior art that since each of the first guide plates (391) forms an upper flap (399) at the outer end, the upper flap (399) may slightly retard the formation of rain, although the rain is still It may flow down from the sinkhole (398), but there is still room for improvement. And each first guide plate (391) is connected to the inner end of each second guide plate (392) with a side plate (396), the side plate (396) is provided with the vent hole (397), when the rain is too heavy , It is still possible that the ventilation gap (D) directly rushes into the ventilation hole (397) to enter the inside of the electric 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 creators of this new type are still willing to continue to work hard to find innovations with better results. For this purpose, an electric box heat dissipation cover is designed, which includes a cover body, wherein the cover body includes a top wall and front, rear, left and right side walls respectively extending downward from the top wall. The front, rear, left and right side wall frames An opening is formed on the enclosure, and the top wall is provided with a plurality of exhaust holes communicating with the opening. The cover is used to cover the top of an electric box, and the opening is used to provide the heat generated by the electric box to escape; it is characterized in that the cover Inside the body, two first guide plates extending from the inside to the left and right side walls are respectively extended from the inner side of the top wall, and from high to low, and a second guide plate with parallel intervals is provided below each first guide plate And each of the first guide plate is formed at the outer end of a lower flap, and the bottom edge of the lower flap and the second guide plate form a first ventilation distance, the first ventilation distance and the plurality of exhaust The outer end of each second guide plate is folded down to form an L-shaped piece, and the bottom cross piece of the L-shaped piece is provided with a plurality of perforations; the inner end of each second guide plate is folded up to form a baffle piece, The top edge of the baffle piece and the first guide piece form a second ventilating distance, the second ventilating distance is in communication with the first ventilating distance; and the top wall extends downwards by two spaced third guide plates, each The third guide plate and the inner end edge of the second guide plate respectively form a third ventilation distance, and the third ventilation distance is in communication with the opening and the second ventilation distance. By forming a bottom flap at the outer end of the first guide plate, it is advantageous for rainwater to flow to the second guide plate and even the plurality of perforations described in the bottom transverse piece of the L-shaped piece, and at the same time use the various perforations. The inner end of the second guide plate is folded up to form a baffle, so that even if the rain is heavy, it can be blocked by an additional baffle. At the same time, the top wall extends downwards with two spaced third guide plates, each of the third guide plates and the inner edge of the second guide plate respectively form a third ventilating distance, and the third ventilating distance and the The opening and the second air gap are connected, so the flow of hot air is still not hindered.
