Description

Technical Field

[0001] The utility model relates to the technical field of local boxes, in particular to a waterproof, dust-proof and heat-dissipating eaves for a local box.

Background Art

[0002] At present, when high-power equipment (such as frequency converters, etc.) is used inside an outdoor local box, it is very difficult to meet the heat dissipation requirements inside the box by natural cooling or installing an aluminum radiator. It is necessary to install a cooling fan at the back door or side of the box, which consequently reduces the overall protection performance of the box. It is necessary to build a waterproof and sunshade shed at the installation position of the local box later; the waterproof and sunshade shed needs to reserve a certain installation position in advance, and the cost of the waterproof and sunshade shed is relatively high. Moreover, due to the reduction of the protection performance of the local box body, once the coverage area of the waterproof and sunshade shed fails to meet the standard, there is a risk of water and dust entering the local box. Thus, the use cost is high and the waterproof and dust-proof reliability is poor.

Content of the Utility Model

[0003] The purpose of the utility model is to solve the problems in the prior art, and propose a waterproof, dust-proof and heat-dissipating eaves for a local box, which can reduce the use cost and improve the waterproof and dust-proof reliability.

[0004] To achieve the above purpose, the utility model proposes a waterproof, dust-proof and heat-dissipating eaves for a local box, including an inner layer of the eaves. An outer layer of the eaves is provided on the inner layer of the eaves. A cavity is provided between the inner layer of the eaves and the outer layer of the eaves. A blower is provided on the lower side of the inner layer of the eaves. A through hole corresponding to the blower is provided on the inner layer of the eaves. A mesh ventilation area located outside the box is provided on the inner layer of the eaves.

[0005] Preferably, the mesh ventilation area surrounds the box in a complete circle.

[0006] Preferably, a waterproof and dust-proof cotton layer is provided on the mesh ventilation area.

[0007] Preferably, the top of the outer layer of the eaves is in a herringbone shape.

[0008] Preferably, a frame-shaped connecting body located inside the box is provided on the inner layer of the eaves, and fixing holes are provided on the frame-shaped connecting body.

[0009] Preferably, a plurality of downward-opening annular arches are provided on the inner layer of the eaves between the through hole and the mesh ventilation area. The annular arches are sleeved in sequence according to the size of the diameter, and the cross section of the annular arch is in an arc shape.

[0010] Advantages of the present utility model: By providing a cavity between the inner layer and the outer layer of the brim, a blower is provided on the lower side of the inner layer of the brim, through holes corresponding to the blower are provided on the inner layer of the brim, and a mesh ventilation area located outside the box body is provided on the inner layer of the brim. Since the outer layer of the brim still has the original waterproof and dustproof capabilities, compared with the prior art, it can reduce the use cost and improve the reliability of waterproof and dustproof.

[0011] The features and advantages of the present utility model will be described in detail through embodiments in conjunction with the accompanying drawings.

Description of the Drawings

[0012] Figure 1 is a schematic cross-sectional structure diagram of a waterproof, dustproof and heat-dissipating brim of a local box of the present utility model.

[0013] In the figure: 1 - inner layer of the brim, 2 - outer layer of the brim, 3 - cavity, 4 - blower, 5 - through hole, 6 - box body, 7 - mesh ventilation area, 8 - waterproof and dustproof cotton layer, 9 - annular arch, 10 - frame-shaped connecting body, 11 - fixing hole.

Specific Embodiments

[0014] Refer to Figure 1 , a waterproof, dustproof and heat-dissipating brim of a local box of the present utility model includes an inner layer 1 of the brim. A blower 4 is provided on the lower side of the inner layer 1 of the brim. Through holes 5 corresponding to the blower 4 are provided on the inner layer 1 of the brim. A mesh ventilation area 7 located outside the box body 6 is provided on the inner layer 1 of the brim.

[0015] The mesh ventilation area 7 surrounds the box body 6 in a complete circle.

[0016] A waterproof and dustproof cotton layer 8 is provided on the mesh ventilation area 7.

[0017] The top of the outer layer 2 of the brim is in a herringbone shape.

[0018] A frame-shaped connecting body 10 located inside the box body 6 is provided on the inner layer 1 of the brim, and fixing holes 11 are provided on the frame-shaped connecting body 10.

[0019] A plurality of annular arches 9 with openings facing downwards are provided on the inner layer 1 of the brim between the through holes 5 and the mesh ventilation area 7. The annular arches 9 are sleeved in sequence according to the size of the diameters, and the cross-section of the annular arches 9 is in an arc shape.

[0020] Working process of the present utility model:

[0021] During the working process of a waterproof, dustproof and heat-dissipating brim of a local box of the present utility model, the hot air inside the box body 6 enters the cavity 3 through the through holes 5 under the action of the blower 4, then passes through the waterproof and dustproof cotton layer 8, and finally is discharged from the mesh ventilation area 7.

[0022] When the fan 4 does not need to work, the waterproof and dustproof cotton layer 8 prevents external water vapor and dust from entering the cavity 3 through the mesh ventilation area 7, further improving the waterproof and dustproof effect.

[0023] The annular arch 9 increases the heat dissipation area of the inner layer 1 of the brim, improving the heat dissipation effect.

[0024] The above embodiments are illustrative of the present utility model and not restrictive thereof. Any scheme obtained by simply changing the present utility model falls within the protection scope of the present utility model.
