Description

Technical Field

[0001] This application relates to the technical field of distribution boxes, and more particularly to an outdoor distribution box with a heat dissipation channel. Background Art

[0002] A distribution box includes a box body, and a plurality of electrical modules are arranged inside the box body. The box body provides external protection for the internal electrical modules. Electrical operators can open the door of the box body, switch on and off each circuit, and distribute electric energy. It is a commonly used electrical equipment. Since there are a plurality of electrical modules inside the distribution box, when the electrical modules are working, the temperature inside the distribution box is relatively high. High temperature may cause the performance of electrical components to decline and the service life to be shortened. Therefore, improving the heat dissipation ability of the distribution box is one of the core technical issues concerned in the industry.

[0003] Our company currently has an outdoor distribution box, as Figure 1 shown, which includes a box body 90. Both sides of the box body 90 are provided with a ventilation opening 901, which is communicated with the chamber inside the box body 90 through the ventilation opening 901, so as to facilitate the heat exchange between the electrical modules in the chamber and the external air to reduce the temperature in the chamber. However: In the embodiment of this application, when the temperature inside the chamber is relatively high, the air inside the chamber expands and the air pressure rises. At this time, the hot air is discharged outwards from the two ventilation openings 901 until all the expanded air is discharged to the outside and the air pressure in the chamber is basically the same as that of the outside. It is easy to see that in this process, more hot air is discharged from the chamber to the outside, and less cold air flows into the chamber from the outside, and the heat dissipation efficiency needs to be improved.

[0004] Therefore, there is a need to provide an outdoor distribution box with a heat dissipation channel that is easy for cold air from the outside to flow in and has better heat dissipation performance. Summary of the Invention

[0031] Application Overview

[0032] There is currently an outdoor distribution box that discharges a relatively large amount of hot air from the chamber and a relatively small amount of cold air flowing into the chamber from the outside, and the heat dissipation efficiency needs to be improved.

[0033] Based on the above technical problems, the present application proposes an outdoor distribution box with a heat dissipation channel. Among them, the outdoor distribution box with a heat dissipation channel has a simple structure, does not involve complex manufacturing processes and expensive materials, has high economy. At the same time, for manufacturers, the outdoor distribution box with a heat dissipation channel provided by the present application is easy to produce and has a low cost, which is more conducive to controlling production costs and further conducive to product promotion and use.

[0034] Schematic of an outdoor distribution box with a heat dissipation channel

[0035] Reference Figures 2 to 6 , according to a preferred embodiment of the present utility model, an outdoor distribution box with a heat dissipation channel, as Figure 2 and Figure 3 shown, includes a distribution box body 10. The side of the distribution box body 10 has a plurality of first heat dissipation channels 101. The top of the distribution box body 10 has a second heat dissipation channel 102. The first heat dissipation channels 101 are arranged along the height direction of the distribution box body 10, and the air inlet of the first heat dissipation channels 101 is close to the bottom of the distribution box body 10. The air outlet of the first heat dissipation channels 101 is communicated with the second heat dissipation channel 102. The second heat dissipation channel 102 has a plurality of ventilation holes 1021 communicating with the outside. The distribution box body 10 has a receiving cavity 107 for accommodating electrical components, and the receiving cavity 107 is communicated with the second heat dissipation channel 102.

[0036] Specifically, to form the first heat dissipation channels 101, as Figure 2 , Figure 3 and Figure 4As shown, the outdoor distribution box with a heat dissipation channel further includes a plurality of plates 20. Both sides of the plate 20 are attached to the distribution box body 10, and the middle section of the plate 20 is spaced from the side surface of the distribution box body 10 by a predetermined distance. The plate 20 and the side surface of the distribution box body 10 together form the first heat dissipation channel 101.

[0037] It should be noted that in the embodiment of the present application, the number of the plates 20 is two. The two plates 20 are respectively located on both sides of the distribution box body 10. Each plate 20 is in a U shape, and both ends of the U shape have bent flanges 203. The flanges 203 are attached to the side surface of the distribution box body 10. The area between the middle section of the plate 20 and the side wall of the distribution box body 10 is in a U-shaped groove. The bottom of the plate 20 is close to the bottom of the distribution box body 10, and the top of the plate 20 is close to the top of the distribution box body 10. Since the plate 20 is vertically penetrated in the height direction of the distribution box body 10, and when the distribution box body 10 is working, the temperature in the accommodation cavity 107 is relatively high, and the side wall temperature of the distribution box body 10 is also relatively high. Then the temperature of the first heat dissipation channel 101 formed by the plate 20 and the side wall of the distribution box body 10 is usually higher than the room temperature. Then the hot air in the first heat dissipation channel 101 flows upward along the U-shaped groove and flows to the second heat dissipation channel 102, and is finally discharged to the outside, and a pressure difference is formed between the upper and lower regions of the first heat dissipation channel 101. Then the outside cold air rushes into the first heat dissipation channel 101 from the opening below the plate 20 under the action of the pressure difference, forming a chimney effect. It is easy to see that in this process, the outside air with a lower temperature is easy to rush into the first heat dissipation channel 101, and after taking away the heat of the side wall of the distribution box body 10, it is discharged. Compared with the prior art, it has the advantages of better heat dissipation performance when the outside cold air rushes in.

[0038] In addition, to form the second heat dissipation channel 102, as Figure 2 、 Figure 3 and Figure 5 shown, the outdoor distribution box with a heat dissipation channel further includes a top cover 30. The top cover 30 is arranged on the top of the distribution box body 10. The top cover 30 has a concave cavity 301. The side wall of the concave cavity 301 has a plurality of ventilation holes 3011. The concave cavity 301 and the top wall of the distribution box body 10 together form the second heat dissipation channel 102. The concave cavity 301 is communicated with the top of the first heat dissipation channel 101.

[0039] In addition, to realize the communication between the accommodation cavity 107 and the second heat dissipation channel 102, as Figure 3 and Figure 6As shown, the distribution box body 10 has a plurality of annular protrusions 103. The annular protrusions 103 extend upward from the top of the distribution box body 10 by a predetermined distance and are placed in the concave cavity 301. Each annular protrusion 103 has a circulation hole 1031. Two ends of the circulation hole 1031 are respectively communicated with the accommodation cavity 107 and the second heat dissipation channel 102.

[0040] It should be noted that by providing the annular protrusion 103 at the upward extension of the edge of the circulation hole 1031, the risk that external rainwater splashes into the second heat dissipation channel 102 through the ventilation hole 1021 and then flows into the accommodation cavity 107 through the circulation hole 1031 is avoided.

[0041] Furthermore, to realize the connection between the plate body 20 and the distribution box body 10, as Figure 6 shown, both sides of the distribution box body 10 have a bent extension 104 and a plurality of first connection holes 105. The bent extension 104 and the side surface of the distribution box body 10 together form an installation groove (not marked in the figure). One side of the plate body 20 extends into the installation groove. The other side of the plate body 20 has a plurality of second connection holes (not marked in the figure) corresponding to the first connection holes 105 one by one. Each first connection hole 105 is directly opposite to the corresponding second connection hole.

[0042] In addition, as Figure 6 shown, the bottom of each installation groove has a supporting portion 1041. When one side of the plate body 20 extends into the bent extension 104, the bottom of the plate body 20 abuts against the supporting portion 1041.

[0043] It should be noted that during installation, the installer first inserts one side of the plate body 20 into the installation groove. The supporting portion 1041 provides support for the side of the plate body 20 extending into the installation groove, and aligns the first connection hole 105 with the second connection hole. Then, bolts are sequentially screwed into the second connection hole and the first connection hole 105. By providing the installation groove and the supporting portion 1041, the installer can quickly place the plate body 20 in the designated position without spending too much effort to support the plate body 20, which facilitates the bolt connection between the plate body 20 and the distribution box body 10.

[0044] Furthermore, in the embodiment of the present application, after the plate body 20 is connected to the distribution box body 10, to realize the installation of the top cover 30, both ends of the top cover 30 are bolt-connected to the two plate bodies 20 respectively.

[0045] Specifically, to realize the connection between the top cover 30 and the plate body 20, as Figure 4As shown, at one end of each of the plate bodies 20 facing away from the supporting portion 1041, there are two connecting ears 201. On each of the connecting ears 201 and the top cover 30, there are a number of threaded holes (not marked in the figure). Each of the connecting ears 201 is bolted to the top cover 30 through bolts.

[0046] Further, to accelerate the upward flow of air, the cross-sectional area of the first heat dissipation channel gradually decreases in the height direction of the distribution box body. More specifically, as Figure 4 shown, the two side walls of the U-shaped groove have symmetrically arranged inclined surfaces 202, and the distance between the two inclined surfaces 202 gradually narrows from bottom to top.

[0047] Further, when water enters the second heat dissipation channel 102, for the convenience of rainwater drainage, as Figure 5 shown, one end of the top cover 30 close to the cavity opening of the concave cavity 301 has a number of water drainage notches 302. The two ends of the water drainage notches 302 are respectively communicated with the concave cavity 301 and the outside.

[0048] In addition, as Figure 6 shown, the top of the distribution box body 10 has a number of slopes 106. The slopes 106 correspond to the water drainage notches 302 one by one. Below each of the water drainage notches 302, there is one of the slopes 106.

[0049] It should be noted that in the embodiment of the present application, since the ventilation holes 3011 are provided on the side of the top cover 30, when rainwater falls on the top surface of the top cover 30, it is difficult for the rainwater to fall into the second heat dissipation channel 102. And when the rainwater splashes into the second heat dissipation channel 102 obliquely from the ventilation holes 3011, it is easy to fall on the slopes 106 and slide freely from the slopes 106.

[0050] In summary, the outdoor distribution box with a heat dissipation channel based on the embodiment of the present application is clarified, which provides advantages such as easy influx of cold air from the outside and better heat dissipation performance for the outdoor distribution box with a heat dissipation channel.

[0051] It is worth mentioning that in the embodiment of the present application, the outdoor distribution box with a heat dissipation channel has a simple structure, does not involve complex manufacturing processes and expensive materials, and has high economy. At the same time, for manufacturers, the outdoor distribution box with a heat dissipation channel provided by the present application is easy to produce and has a low cost, which is more conducive to controlling production costs and further conducive to product promotion and use.

The object of the present utility model has been completely and effectively achieved.
