[0002] Distribution boxes are an important component of power distribution systems, primarily used to distribute power from one or more sources to multiple circuits. Their function is not only to manage the flow of power safely and efficiently, but also to provide necessary protection to ensure the safety of electrical equipment and personnel.

[0003] In existing distribution boxes, simple heat dissipation slots are usually used to cool the inside of the distribution box. However, these simple heat dissipation slots often cannot provide sufficient heat dissipation, which may result in poor performance of the distribution box, thereby reducing the heat dissipation of the distribution box and shortening its service life. To address this, we propose a heat dissipation device for distribution boxes. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] This utility model provides a technical solution: such as Figures 1-7 As shown, in this embodiment, a heat dissipation device for a power distribution box includes a power distribution box body 1. A thermally conductive pad 13 is fixedly connected between the inner walls of the power distribution box body 1. An electronic component 14 and a current-carrying busbar 25 are fixedly mounted on one side of the thermally conductive pad 13. An insulating paper 16 is fixedly connected to the side of the thermally conductive pad 13 away from the electronic component 14 and the current-carrying busbar 25. A water-cooling structure is provided on one side of the insulating paper 16. The water-cooling structure is used to cool the electronic component 14 and the current-carrying busbar 25. An air-cooling assembly is provided inside the power distribution box body 1. The component is used to regulate the internal temperature of the power distribution box body 1. A protective door 2 is provided on one side of the power distribution box body 1. A locking structure is provided on the outside of the protective door 2. The locking structure is used to lock the protective door 2. Two first connecting plates 5 are fixedly connected to one side of the power distribution box body 1. A rotating cylinder 6 is fixedly connected to the top of each of the two first connecting plates 5. Two second connecting plates 7 are fixedly connected to one side of the protective door 2. A rotating block 18 is fixedly connected to the bottom of each of the two second connecting plates 7. The two rotating blocks 18 rotate between the inner walls of the two rotating cylinders 6 respectively.

[0026] When the distribution box is cooled, the distribution box body 1 is first connected to an external power source. Then, the electronic components 14 and the current-carrying busbar 25 are activated. The electronic components 14 and the current-carrying busbar 25 generate heat, which is diffused into the interior of the distribution box body 1 by the heat-conducting pad 13. The insulating paper 16 ensures the safe operation of the electronic components 14 and the current-carrying busbar 25. Then, the water-cooling structure initially cools the electronic components 14 and the current-carrying busbar 25. Next, the air-cooling component further cools the interior of the distribution box body 1. Then, the rotating blocks 18 at the bottom of the two second connecting plates 7 rotate inside the rotating cylinders 6 at the top of the two first connecting plates 5, which makes it convenient for the user to open the protective door 2 for maintenance of the interior of the distribution box body 1. Finally, the locking structure locks the protective door 2 to ensure the safe operation of the interior of the distribution box body 1, thereby improving the performance of the distribution box.

[0027] like Figures 1-7 As shown, the water-cooled structure includes a liquid cooling plate 15, which is fixedly connected to one side of the insulating paper 16. A water inlet 8 and a water exchange inlet 9 are fixedly connected to one side of the liquid cooling plate 15. One end of the water inlet 8 and the water exchange inlet 9 passes through the insulating paper 16 and the heat-conducting pad 13 and extends to the outside of the power distribution box body 1. A circulation channel 17 is opened inside the liquid cooling plate 15, and one end of the water inlet 8 and the water exchange inlet 9 communicates with the inside of the circulation channel 17.

[0028] By connecting the water inlet 8 and the water outlet 9 to the external water inlet pipe and water outlet pipe respectively, the cooling water circulates inside the circulation channel 17, which allows the liquid cooling plate 15 to initially cool the inside of the power distribution box body 1, thereby improving the quality of use of the power distribution box.

[0029] like Figures 1-7 As shown, the air-cooled assembly includes a mounting slot 24, which is opened on one side inside the power distribution box body 1. A fan blade 10 is rotatably connected between the inner walls of the mounting slot 24. A heat dissipation slot 12 is opened on one side of the power distribution box body 1. A heat dissipation motor 4 is fixedly installed on one side of the power distribution box body 1. The output end of the heat dissipation motor 4 extends into the interior of the mounting slot 24 and is fixedly connected to the fan blade 10.

[0030] The cooling motor 4 drives the fan blades 10 to rotate inside the mounting slot 24, thereby dissipating the heat inside the power distribution box body 1 along the heat dissipation slot 12, thus improving the heat dissipation quality of the heat dissipation device.

[0031] like Figures 1-7As shown, the locking structure includes a lock box 3, which is fixedly connected to one side of the protective door 2. A sliding groove 20 is provided on one side of the lock box 3, which communicates with the interior of the lock box 3 and passes through the protective door 2. A slider 22 is slidably connected between the inner walls of the lock box 3. A push rod 19 and a connecting rod 26 are fixedly connected to both sides of the slider 22, respectively. The push rod 19 and the connecting rod 26 are slidably connected between the inner walls of the sliding groove 20. A lock groove 11 is provided on one side of the interior of the power distribution box body 1. A lock block 23 is fixedly connected to one end of the connecting rod 26. The lock block 23 contacts the inner side of the lock groove 11. A return spring 21 is fixedly connected between the slider 22 and the inner side of the lock box 3.

[0032] By pushing the push rod 19 to slide between the inner walls of the slide groove 20, the slider 22 is driven to move between the inner walls of the lock box 3, and the return spring 21 made of high carbon steel is pressed, so that the connecting rod 26 drives the lock block 23 to move. Then, the elasticity of the return spring 21 made of high carbon steel pushes the slider 22 to move, so that the connecting rod 26 drives the lock block 23 to be locked into the interior of the lock groove 11, thereby improving the protection of the distribution box.

[0033] This utility model provides a heat dissipation device for a power distribution box. The specific working principle is as follows: When the power distribution box is dissipating heat, the power distribution box body 1 is first connected to an external power source. Then, the electronic components 14 and current-carrying busbars 25 are activated. The electronic components 14 and current-carrying busbars 25 generate heat, which is diffused into the interior of the power distribution box body 1 through the heat-conducting pad 13. The insulating paper 16 ensures the safe operation of the electronic components 14 and current-carrying busbars 25. Then, by connecting the water inlet 8 and water outlet 9 to the external water inlet and outlet pipes respectively, cooling water circulates within the circulation channel 17, allowing the liquid cooling plate 15 to initially cool the electronic components 14 and current-carrying busbars 25 inside the power distribution box body 1. Next, an external power source is connected via an external controller, which activates the cooling motor 4. The cooling motor 4 drives the fan blades 10 within the mounting slot 24. The rotation of the distribution box body 1 allows heat to be discharged along the heat dissipation groove 12, further cooling the interior of the distribution box body 1. Then, the rotating blocks 18 at the bottom of the two second connecting plates 7 rotate inside the rotating cylinder 6 at the top of the two first connecting plates 5, making it convenient for the user to open the protective door 2 for maintenance of the interior of the distribution box body 1. Next, by pushing the push rod 19 to slide between the inner walls of the slide groove 20, the slider 22 moves between the inner walls of the lock box 3, and presses the return spring 21 made of high carbon steel, causing the connecting rod 26 to move the locking block 23. Subsequently, the elasticity of the return spring 21 made of high carbon steel pushes the slider 22 to move, causing the connecting rod 26 to drive the locking block 23 into the lock groove 11, thereby locking the protective door 2 and ensuring the safe operation of the distribution box body 1. This completes the heat dissipation of the distribution box.
