Description

Technical Field

[0001] The invention relates to a radiator, in particular to a heat dissipation cover of an electric box. Background Art

[0002] Power companies and communications companies provide power and communications services to various businesses and households, and many electrical boxes (or transformer boxes) are installed in the middle process and path for power distribution or communication data transmission. Since the inside of the electrical box may generate heat due to power or communication data transmission, various heat dissipation mechanisms are needed to solve the heat dissipation problem. Some companies cooperate with the power company or communications company to provide a heat dissipation cover for the electrical box. The necessary condition of the heat dissipation cover is of course that it must be able to remove the heat inside the electrical box, and it must also prevent rainwater from splashing into the electrical box and causing parts to rust or short circuit. Therefore, the applicant of this case has invented and applied for a "radiator" in Taiwan, China, No. 108147894 (applied on the same day of the invention, Taiwan, China, Application No. 108217278), which is used to solve the heat dissipation and water splashing.

[0003] The prior art is generally Figure 6 As shown, the heat dissipation cover of the electric box includes a cover body 3, wherein the cover body 3 includes a top wall 31 and a front side wall (not shown), a rear side wall 33, a left side wall 34 and a right side wall 35 respectively extending downward from the top wall 31, the front, rear, left and right side walls are framed to form an opening 36, and the top wall 31 is provided with a plurality of exhaust holes 37 communicating with the opening 36. The cover body 3 is used to cover the top of an electric box (not shown in the figure), and the opening 36 is used to provide heat generated by the electric box for exhaust.

[0004] The background technology The inside of the cover body 3 is respectively extended from the inner side of the top wall 31 to form two first guide plates 391 from the inside to the left and right sides, and a parallel and spaced second guide plate 392 is provided below each first guide plate 391; and each first guide plate 391 forms an upper folding piece 399 at the outer end, and each first guide plate 391 is provided with a plurality of water drop holes 398 near the upper folding piece 399, and a ventilation distance D is formed between the first guide plate 391 and the second guide plate 392, and 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 bottom horizontal piece 394 of the L-shaped piece 393 is provided with a plurality of through holes 395; each first guide plate 391 and the inner end of each second guide plate 392 are connected to a side plate 396, and the side plate 396 is provided with a ventilation hole 397.

[0005] When the hot air of the electric box escapes from the top of the electric box to the opening 36, it flows from each of the air holes 397 to each of the ventilation distances D, and then the hot air flows through the gap at the rear end of each of the upper folding pieces 399, or from each of the water drop holes 398, into the space above each of the first guide plates 391, and escapes from the plurality of exhaust holes 37 of the top wall 31. Although the background art also provides the aforementioned first guide plates 391, second guide plates 392, etc. to prevent rainwater from entering the interior of the electric box, and guides the rainwater to flow out of the plurality of through holes 395 provided on the bottom horizontal piece 394 of the L-shaped piece 393, it is found in the background art that since each of the first guide plates 391 forms an upper folding piece 399 at the outer end, the upper folding piece 399 may slightly block the rainwater, although the rainwater may still flow down from the water drop holes 398, there is still room for improvement. The inner ends of each first guide plate 391 and each second guide plate 392 are connected to a side plate 396, and the side plate 396 is provided with the air vent 397. When the rain is too heavy, it is still possible to rush into the air vent 397 through the ventilation gap D and enter the interior of the electrical box. Summary of the invention
