Description

Technical Field

[0001] The utility model relates to the technical field of integrated distribution boxes, in particular to an internal ventilation device for an integrated distribution box.

Background Art

[0002] There are two heat dissipation methods for components of a conventional integrated distribution box. One is natural ventilation and heat dissipation through louvers, and the other is forced refrigeration by a fan. However, for conventional forced refrigeration by a fan, the fan is placed outside the integrated distribution box, which is equivalent to being used outdoors. The air inside the box is pumped out by the fan, and the air flow direction is from the distribution box to the outside. This is not conducive to heat dissipation, and the ventilation effect and ventilation volume are poor.

Content of the Utility Model

[0003] The purpose of the utility model is to solve the problems in the prior art, and provide an internal ventilation device for an integrated distribution box, which can facilitate heat dissipation and improve the ventilation effect and ventilation volume.

[0004] To achieve the above purpose, the utility model provides an internal ventilation device for an integrated distribution box, including a housing cover. The housing cover is provided with a natural ventilation area and a forced ventilation area. The natural ventilation area is provided with natural ventilation holes arranged in an array, and the forced ventilation area is provided with an axial flow fan.

[0005] Preferably, skirt edges are provided at both the front and rear ends of the housing cover, and fixing holes are provided on the skirt edges.

[0006] Preferably, open openings corresponding to the natural ventilation area are provided at both the upper and lower ends of the housing cover.

[0007] Preferably, the forced ventilation area is provided with forced ventilation holes, and a dust-proof net and an axial flow fan are respectively provided at the inner and outer ends of the forced ventilation holes in the forced ventilation area.

[0008] Preferably, the axial flow fan is fixedly connected to the housing cover by riveting.

[0009] The beneficial effects of the utility model: The housing cover of the utility model is installed inside the bottom of the integrated distribution box and covers the bottom louvers of the integrated distribution box. The air outlet direction of the axial flow fan directly faces the top cover. The air enters from the lower louvers, and the axial flow fan at the upper part sucks the air. The air flow generated by the axial flow fan blows away a large amount of heat in the component chamber. Because cold air descends and hot air rises, heat exchange is completed, and the heat dissipation effect is better. The natural ventilation area is provided with natural ventilation holes arranged in an array to achieve dual heat dissipation of natural ventilation and forced heat dissipation, further improving the heat dissipation effect, and natural ventilation and heat dissipation can be used alone according to the ambient temperature. Compared with the prior art, it can facilitate heat dissipation and improve the ventilation effect and ventilation volume.

[0010] The features and advantages of the present utility model will be described in detail through embodiments in conjunction with the accompanying drawings.

Explanation of the Drawings

[0011] Figure 1 It is a schematic structural diagram of a built-in ventilation device in a comprehensive distribution box of the present utility model.

[0012] In the figure: 1 - shell cover, 2 - natural ventilation area, 3 - forced ventilation area, 4 - natural ventilation holes, 5 - axial flow fan, 6 - skirt, 7 - fixing holes, 8 - forced ventilation holes, 9 - dust-proof net, 10 - open mouth.

Specific Embodiments

[0013] Refer to Figure 1 , a built-in ventilation device in a comprehensive distribution box of the present utility model includes a shell cover 1. The shell cover 1 is provided with a natural ventilation area 2 and a forced ventilation area 3. The natural ventilation area 2 is provided with natural ventilation holes 4 arranged in an array, and the forced ventilation area 3 is provided with an axial flow fan 5.

[0014] Skirts 6 are provided at both the front and rear ends of the shell cover 1, and fixing holes 7 are provided on the skirts 6.

[0015] Open mouths 10 corresponding to the natural ventilation area 2 are provided at both the upper and lower ends of the shell cover 1.

[0016] Forced ventilation holes 8 are provided in the forced ventilation area 3, and a dust-proof net 9 and an axial flow fan 5 are respectively provided at the inner and outer ends of the forced ventilation holes 8 in the forced ventilation area 3.

[0017] The axial flow fan 5 is fixedly connected to the shell cover 1 by riveting.

[0018] Working process of the present utility model:

[0019] During the working process of a built-in ventilation device in a comprehensive distribution box of the present utility model, by installing the shell cover 1 inside the bottom of the comprehensive distribution box and covering the bottom louver of the comprehensive distribution box, the air outlet direction of the axial flow fan 5 directly faces the top cover. Air enters from the lower louver, and the axial flow fan 5 at the upper part sucks air. The air flow generated by the blowing of the axial flow fan 5 takes away a large amount of heat in the component chamber. And because cold air descends and hot air rises, heat exchange is completed, and the heat dissipation effect is better. Through the natural ventilation holes 4 arranged in an array on the natural ventilation area 2, dual heat dissipation of natural ventilation and forced ventilation is realized, further improving the heat dissipation effect, and natural ventilation heat dissipation can be used alone according to the ambient temperature. Compared with the prior art, it can facilitate heat discharge, improve the ventilation effect and ventilation volume.

[0020] The above embodiments are descriptions of the present utility model, not limitations of the present utility model. Any solution obtained by simply transforming the present utility model belongs to the protection scope of the present utility model.
