For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0034] As described in the background technology, a distribution box is a distribution device used to distribute electricity. It is used to distribute large current from one phase to multiple phases or perform other distributions, and provide protection and control for the distribution network. The top cover of the existing distribution box is usually a sealed structure, resulting in poor heat dissipation. In order to ensure the temperature rise of the distribution box and reduce the loop resistance, it is necessary to increase the amount of copper busbars, resulting in increased costs.
[0035] Based on this, please refer to Figure 1-Figure 5The embodiment of the utility model provides a top cover structure 100 and a distribution box 1000, which can effectively improve the above-mentioned technical problems, that is, it can reduce the amount of copper busbars used in the distribution box 1000, reduce costs, and have a good heat dissipation effect. The top cover structure 100 and the distribution box 1000 will be described in detail below.
[0036] Please refer to Figure 1 , Figure 1 A schematic diagram of the structure of the distribution box 1000 provided in this embodiment from a first perspective, combined with Figure 1 The distribution box 1000 includes a top cover structure 100 and a box body 200, and the top cover structure 100 is arranged in the box body 200. It is easy to understand that the box body 200 has various components, which will generate heat when working.
[0037] Specifically, please refer to Figure 2 , Figure 2 The schematic diagram of the structure of the top cover structure 100 provided in this embodiment from a first perspective, combined with Figure 1 and Figure 2 The top cover structure 100 includes a top plate 10 and a side plate 20. The side plate 20 is connected to the top plate 10 and forms a ventilation cavity 30 with the top plate 10. The side plate 20 is provided with a louver 21, and the louver 21 is connected to the ventilation cavity 30. In other words, the louver 21 can be connected to the box body 200 through the ventilation cavity 30. The heat generated by the components in the box body 200 during operation can be directly discharged from the louver 21 through the ventilation cavity 30. The overall temperature rise is good, the amount of copper busbars can be reduced, and the cost is reduced. Therefore, the top cover structure 100 can reduce the amount of copper busbars used in the distribution box 1000, save costs, and improve the heat dissipation effect.
[0038] In order to better ventilate and dissipate heat for the components in the box 200, please refer to Figure 3 , Figure 3 A schematic diagram of the structure of the distribution box 1000 provided in this embodiment from a second perspective, combined with Figure 3 In this embodiment, an air inlet 210 is provided at the bottom of the box 200, and the air inlet 210, the ventilation cavity 30 and the louver 21 are connected in sequence; through the setting of the air inlet 210, air can enter from the bottom of the box 200 and exit from the louver 21 of the upper top cover structure 100, thereby forming a heat dissipation effect of air thermal convection. In other words, according to the principle that hot air flows upward and cold air flows downward, the heat generated by the components in the box 200 during operation will form hot air discharged through the louver 21, while the relatively cold external environment air will enter from the air inlet 210 at the bottom of the box 200, thereby continuing to dissipate heat for the components, forming a ventilation and heat dissipation effect of air circulation, and further improving the heat dissipation efficiency.
[0039] It should be noted that, in some other embodiments, an air inlet hole 210 may also be opened on the side of the box body 200, as long as the heat dissipation effect of air heat convection can be formed.
[0040] In addition, if Figure 3 As shown, in the present embodiment, there are multiple air inlet holes 210 , and the multiple air inlet holes 210 are arranged at intervals. It should be noted that the specific arrangement of the multiple air inlet holes 210 needs to be determined according to the layout positions of various components in the box body 200 .
[0041] Please continue to combine Figure 3 In order to facilitate cable installation, in this embodiment, a cable hole 220 is further opened at the bottom of the box 200. The cable is connected to the components in the box 200 through the cable hole 220. This bottom entry method can also protect the cable to a certain extent.
[0042] Please continue to combine Figure 2 Specifically, the side panel 20 includes a first side panel 22 and a second side panel 23. The first side panel 22 and the second side panel 23 are arranged opposite to each other and form a ventilation cavity 30 with the top panel 10. In this embodiment, both the first side panel 22 and the second side panel 23 are provided with louvers 21. In this way, after air enters from the air inlet 210 at the bottom of the box body 200, the heat generated by the components can be discharged from the louvers 21 of the first side panel 22 and the second side panel 23 respectively.
[0043] It is easy to understand that in this embodiment, the louvers 21 arranged on the two opposite sides of the top cover structure 100 can also produce air convection effect to a certain extent, further improving the heat dissipation efficiency. Of course, in other embodiments, the louvers 21 can be arranged only on the first side plate 22, or only on the second side plate 23, so as to achieve the heat convection effect of bottom air intake and louvers 21 air outlet.
[0044] In order to further improve the heat dissipation efficiency, in this embodiment, the number of louvers 21 on the first side plate 22 and the second side plate 23 are both multiple, and the multiple louvers 21 are arranged at intervals. In order to improve the air convection conduction effect of the top cover structure 100, the multiple louvers 21 on the first side plate 22 and the multiple louvers 21 on the second side plate 23 can be arranged one by one.
[0045] In detail, in order to prevent rainwater from flowing into the box body 200 through the louver 21, please refer to Figure 4 , Figure 4 for Figure 2 The enlarged view of the A part in the figure, combined with Figure 2 and Figure 4The top cover structure 100 further includes a waterproof cover 40, which is disposed on a side of the louver 21 close to the top plate 10, and the waterproof cover 40 is extended in a direction away from the ventilation cavity 30. In other words, the waterproof cover 40 is extended in a direction away from the ventilation cavity 30 to form a structure similar to a boss, thereby providing protection for the louver 21 and preventing rainwater from entering the box body 200 through the louver 21.
[0046] Of course, in order to further improve the waterproof effect, the waterproof cover 40 can also be extended in the direction away from the top plate 10, that is, extended in the direction of the box body 200, and this setting can also reduce the dust from entering the box body 200 through the louver 21 to a certain extent.
[0047] Furthermore, the waterproof cover 40 includes a first arc portion 41, a connecting portion 42 and a second arc portion 43 connected in sequence, the connecting portion 42 is arranged on a side of the louver 21 close to the top plate 10, and the first arc portion 41 and the second arc portion 43 are bent and extended in a direction away from the top plate 10. Figure 4 As shown, in this embodiment, the first arc portion 41, the connecting portion 42 and the second arc portion 43 are sequentially connected to form a structure similar to a "C" shape, which can facilitate the drainage of rainwater from the first arc portion 41 and the second arc portion 43 when rainwater falls into the connecting portion 42, thereby preventing rainwater from entering the louver 21. Of course, in other embodiments, the shape of the waterproof cover 40 can also be a trapezoidal, rectangular or inverted "V" shape.
[0048] Please refer to Figure 5 , Figure 5 A schematic diagram of the structure of the top cover structure 100 provided in this embodiment from a second perspective, combined with Figure 3 and Figure 5 The top cover structure 100 further includes a first bottom plate 50 and a second bottom plate 60 which are arranged opposite to each other. The first bottom plate 50 is connected to the first side plate 22 and is spaced apart from the top plate 10; the second bottom plate 60 is connected to the second side plate 23 and is spaced apart from the top plate 10. The top cover structure 100 is specifically connected to the top of the box body 200 through the first bottom plate 50 and the second bottom plate 60. This arrangement can improve the connection stability of the top cover structure 100 and also enable the first side plate 22 and the second side plate 23 to extend out of the box body 200, respectively. Figure 1 As shown, an eave is formed, thereby providing a certain rain protection effect for the box body 200, so that after rainwater flows down from the top plate 10, it is not easy to flow into the interior of the box body 200 through the first side plate 22 and the second side plate 23.
[0049] In order to further improve the heat dissipation effect, in this embodiment, the first bottom plate 50 is provided with a first exhaust hole 51, which is communicated with the ventilation cavity 30; the second bottom plate 60 is provided with a second exhaust hole 61, which is communicated with the ventilation cavity 30. In this way, the heat generated by the components in the box body 200 can be discharged through the louver 21, the first exhaust hole 51 and the second exhaust hole 61, and the heat dissipation effect is better. Of course, in some other embodiments, the first exhaust hole 51 can be provided only on the first bottom plate 50, or the second exhaust hole 61 can be provided only on the second bottom plate 60.
[0050] Similarly, in order to further improve the heat dissipation efficiency, the number of the first exhaust holes 51 and the number of the second exhaust holes 61 can be set to be multiple, and the multiple first exhaust holes 51 and the multiple second exhaust holes 61 are arranged at intervals and correspond to each other one by one.
[0051] Please continue to combine Figure 2 In order to prevent water accumulation in the roof structure 100, in this embodiment, the roof plate 10 includes a first roof plate 11 and a second roof plate 12 connected to each other. The first roof plate 11 is connected to the first side plate 22, and the second roof plate 12 is connected to the second side plate 23. The height of the first roof plate 11 gradually decreases toward the first side plate 22, and the height of the second roof plate 12 gradually decreases toward the second side plate 23. Figure 2 As shown, the first top plate 11 and the second top plate 12 form a structure similar to an inverted "V" shape, that is, the first top plate 11 and the second top plate 12 both have a slope, which facilitates rainwater to flow down along the first top plate 11 and the second top plate 12 under the action of its own gravity, thereby preventing the formation of stagnant water and affecting the service life of the top cover structure 100; at the same time, it is not easy for foreign matter to exist on the first top plate 11 and the second top plate 12, and in windy weather, foreign matter such as leaves can also be easily blown away.
[0052] Please continue to combine Figure 2 and Figure 5 In order to further improve the strength of the top cover structure 100, the side panel 20 also includes a third side panel 24 and a fourth side panel 25 that are relatively arranged. The third side panel 24 and the fourth side panel 25 are both connected to the top panel 10, and the first side panel 22, the third side panel 24, the second side panel 23 and the fourth side panel 25 are connected end to end in sequence and form a ventilation cavity 30 with the top panel 10.
[0053] In order to improve the connection stability between the top cover structure 100 and the box body 200, please combine Figure 1 The box body 200 further includes a first fixing plate 230 and a second fixing plate 240 . The first fixing plate 230 is connected to the third side plate 24 , and the second fixing plate 240 is connected to the fourth side plate 25 .
[0054] It should be noted that in some other embodiments, the first fixing plate 230 and the second fixing plate 240 may not be provided, and the third side plate 24 and the fourth side plate 25 may be directly connected and fixed to the upper part of the box body 200. Of course, in order to achieve a better convection ventilation and heat dissipation effect, louvers 21 may also be provided on the third side plate 24 and the fourth side plate 25.
[0055] In summary, the embodiment of the utility model provides a top cover structure 100 and a distribution box 1000, the top cover structure 100 includes a top plate 10 and a side plate 20, the side plate 20 is connected to the top plate 10, and a ventilation cavity 30 is formed between the side plate 20 and the top plate 10, and the side plate 20 is provided with a louver 21, and the louver 21 is connected to the ventilation cavity 30.
