[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1 to 8 This invention provides a technical solution: an automatic heat dissipation distribution box, including a distribution box 1. A heat dissipation fan device 2 and a hot air drive device 3 are provided on the side wall of the distribution box 1. A cooling component 4 is provided between the heat dissipation fan device 2 and the hot air drive device 3. A heat collection device 5 is provided on the top of the distribution box 1. The heat collection device 5 is used to absorb external heat and heat the air inside it before expelling it to drive the hot air drive device 3. The heat dissipation fan device 2 blows the air cooled by the cooling component 4 into the distribution box 1 through the running hot air drive device 3. An automatic cleaning device 6 is also provided on the top of the heat collection device 5. The automatic cleaning device 6 cleans the debris on the surface of the heat collection device 5 under the drive of the air pressure inside the heat collection device 5. The top of the distribution box 1 is provided with a top self-suction hole 11 on one side of the heat collection device 5. On the other side of the distribution box 1, which is symmetrical to the installation of the cooling fan device 2 and the hot air drive device 3, there is a heat dissipation hole 12. After the fan 22 starts to rotate, it will draw air from the outside. The outside air will enter through the top self-suction hole 11, be blown by the fan 22 onto the circuit components inside the distribution box 1, and then blown out through the heat dissipation hole 12.

[0033] In this embodiment, the cooling fan device 2 includes a cooling fan bracket 21, two fans 22 (upper and lower), a fan mounting frame 23, and a cross support frame 24. The side of the cooling fan bracket 21 is fixed to the inner side of the side wall of the distribution box 1, and the top of the cooling fan bracket 21 is connected to the top self-priming hole 11. The fan mounting frame 23 is fixed to the side of the cooling fan bracket 21. The fans 22 are rotatably mounted in the fan mounting frame 23 via the cross support frame 24. The four ends of the cross support frame 24 are welded to the fan mounting frame 23. The hot air drive device 3 includes a mounting frame 31, an air intake shroud 32, an air exhaust shroud 33, and two supercharger turbines 34 (upper and lower). The mounting frame is fixed to the outer surface of the side wall of the distribution box 1. The air intake shroud 32 is fixed to the top of the mounting frame 31, the air exhaust shroud 33 is fixed to the bottom of the mounting frame 31, and the supercharger turbines 34 are fixed to the outer surface of the side wall of the distribution box 1. On the rotating shaft 35, the rotating shaft 35 is rotatably mounted in the fixed frame 31 via the bearing 36. Under normal circumstances, the two booster turbines 34 are driven to rotate by the electricity generated by the solar panel 56 on the top of the rigid gas cylinder 51. The rotating booster turbines 34 drive the coaxial fan 22 to rotate, and the fan 22 will continuously blow air to cool the distribution box. At the same time, the booster turbines 34 continuously pressurize the internal air pipe 54 and the rigid gas cylinder 51. During the process of pressure increase, the air pressure in the cylinder 62 will also increase, causing the piston rod 63 to move outward, pushing the cleaning brush 64 to move and sweep away debris such as leaves and dust on the surface of the solar panel 56 to prevent the effect of the solar panel 56 from being affected. When the air pressure rises to a certain level, the pressure valve 53 opens, the air is released, and the cleaning brush 64 will be bounced back by the spring 67 until the air pressure in the rigid gas cylinder 51 rises again, and so on.

[0034] In this embodiment, the cooling assembly 4 includes a mounting plate 41 symmetrically arranged vertically, a plurality of cooling pipes 42, air-cooling fins 43, a top cooling block 44, and a semiconductor cooling chip 45. The mounting plate 41 is fixed inside the heat dissipation fan bracket 21. The upper and lower ends of the cooling pipes 42 are respectively fixed inside the mounting plate 41 and are filled with coolant. The top of the cooling pipes 42 is inserted into the top cooling block 44. The air-cooling fins 43 are evenly installed on the cooling pipes 42 from top to bottom. The top cooling block 44 is fixed to the mounting plate. On 41, the semiconductor cooling chip 45 is fixed inside the top cooling block 44. The coolant in the cooling pipe 42 has a lower temperature near the semiconductor cooling chip 45, and its specific gravity increases. It will slowly drop and replace the coolant with a higher temperature at the bottom. Through the cooling of the semiconductor cooling chip 45, the coolant in the cooling pipe 42 can always maintain a lower temperature. Then, through the conduction of the air cooling chip 43, the air drawn in from the top self-suction hole 11 is cooled down. Then, this air is blown into the distribution box 1 by the fan to help the distribution box 1 dissipate heat.

[0035] In this embodiment, the heat collection device 5 includes a rigid gas cylinder 51 fixed to the top of the distribution box 1, an external gas pipe 52, a pressure valve 53, an internal gas pipe 54, and a one-way valve 55. One end of the external gas pipe 52 is connected to the side of the rigid gas cylinder 51, and the other end is connected to the hot air drive device 3. The pressure valve 53 is installed on the external gas pipe 52. One end of the internal gas pipe 54 is connected to the hot air drive device 3, and the other end is connected to the bottom of the rigid gas cylinder 51. The one-way valve 55 is installed on the internal gas pipe 54. A solar panel 56 is also provided on the top of the rigid gas cylinder 51 to better absorb sunlight. Its surface is painted black, and in weather with very strong sunlight, its heating process is very fast, and the internal air pressure rises quickly. This allows the pressure valve 53 to open more frequently to expel air, and the rapidly expelled air blows onto the supercharger turbine 34, causing the supercharger turbine 34 to rotate faster. This allows the fan 22 to rotate faster and have better heat dissipation efficiency when the sun is shining directly on it, thus achieving the purpose of automatically increasing heat dissipation efficiency in hot weather. On the other hand, it can also pump and pressurize air into the internal air pipe 54 and the rigid air cylinder 51 more quickly, so that more air is pressurized in the rigid air cylinder 51 and blown out onto the supercharger turbine 34, continuously increasing heat dissipation efficiency, and repeating the cycle.

[0036] In this embodiment, the automatic cleaning device 6 includes an air intake pipe 61, a cylinder 62, a piston rod 63, a cleaning brush 64, and two spring tubes 65. One end of the air intake pipe 61 is connected to an external air pipe 52, and the other end is connected to the tail end of the cylinder 62. One end of the piston rod 63 is slidably mounted inside the cylinder 62, and the other end is connected to the side of the cleaning brush 64. The cylinder 62 is fixed inside a support bracket 66, which is fixed to the top of the distribution box 1. Two springs 67 are provided on the other side of the cleaning brush 64. The springs 64 are respectively mounted inside the spring tubes 65 via spring support rods 68. The heads of the spring support rods 68 are slidably mounted inside the cleaning brush 64. The spring tubes 65 are fixed inside the support bracket 66. Slide rails are provided on the top of the two long side walls of the support bracket 66. The cleaning brush 64 is slidably mounted on the slide rails via slide grooves and is pushed back and forth by the piston rod 63 and the springs 67 to clean the top of the solar panel 56.

[0037] Working principle: Under normal circumstances, the booster turbine 34 is driven to rotate by the electricity generated by the solar panel 56. The booster turbine 34 drives the coaxial fan 22 to rotate, and the fan 22 continuously blows air to cool the distribution box. At the same time, the booster turbine 34 continuously pressurizes the internal air pipe 54 and the rigid gas cylinder 51. During the process of pressure increase, the air pressure in the cylinder 62 is also forced to increase, causing the piston rod 63 to move outward and push the cleaning brush 64 to move, sweeping away debris such as leaves and dust on the surface of the solar panel 56 to prevent the solar panel 56 from being affected. When the air pressure rises to a certain level, the pressure valve 53 opens, the air is released, and the cleaning brush 64 is bounced back by the spring 67 until the air pressure in the rigid gas cylinder 51 rises again, and so on. In the summer when sunlight is strong, the rigid gas cylinder 51 heats up very quickly, and the internal air pressure rises rapidly. This allows the pressure valve 53 to open more frequently to expel air. The rapidly expelled air then blows onto the supercharger turbine 34, increasing its rotation speed. This allows the fan 22 to rotate faster under direct sunlight, drawing in more air from the top self-priming port 11. The air is then cooled by the air cooling fins 43 and blown into the distribution box 1 by the fan, improving its heat dissipation efficiency. This achieves the goal of automatically increasing heat dissipation efficiency in hot weather. On the other hand, it also allows for faster and more continuous pumping and pressurization of air into the internal air pipe 54 and the rigid gas cylinder 51, causing more air to be pressurized in the rigid gas cylinder 51 and blown onto the supercharger turbine 34, continuously increasing heat dissipation efficiency in a continuous cycle.

[0038] Based on the above, this invention can absorb heat from the surrounding environment or sunlight through a rigid gas cylinder with excellent heat absorption properties, heating the air inside. This heated air then activates a cooling fan and a hot air drive device, significantly reducing the operating costs of the electrical distribution box. The heated air pressure rises until the pressure valve opens, and the rapidly flowing air activates a booster turbine. The booster turbine then re-enters the internal air pipes and the rigid gas cylinder, where it is reheated and blown out again, further reducing the operating costs of the booster turbine. The rapidly rotating booster turbine drives a shaft. The rotating fan on the shaft blows the cool air from the cooling components into the distribution box, aiding in the heat dissipation of the electronic components inside. The semiconductor cooling chip in the cooling component cools the coolant in the cooling pipe, and the air cooling chip further increases the cooling efficiency, quickly cooling the outside air drawn in by the fan, thus improving the overall heat dissipation of the distribution box. The invention also uses the process of increasing and decreasing the pressure in the rigid gas cylinder to drive the cleaning brush, which cleans leaves, dust, and other debris from the surface of the solar panels to prevent them from affecting the performance of the solar panels.

[0039] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
