Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] In a specific implementation manner of the present utility model, as Figures 1 to 5 shown, it includes a box body 1, a cover plate 2 installed on the opening of the box body 1, and an electrical component mounting plate 7 installed in the inner cavity of the box body 1. A heat dissipation plate 3 is fixed on the outer surface of the box body 1. A plurality of first heat dissipation fins 4 are fixed on the side of the heat dissipation plate 3 away from the box body 1. A heat dissipation fan 5 is fixed on the heat dissipation plate 3, and the air outlet end of the heat dissipation fan 5 faces the first heat dissipation fins 4; a water cooling component is provided on the first heat dissipation fins 4.

[0030] Specifically, the cover plate 2 can be detachably connected to the box body 1 through a plurality of bolts, or the cover plate 2 is hinged to the box body 1. The electrical component mounting plate 7 is used for mounting various electrical components. The heat dissipation plate 3 is used to absorb the heat of the box body 1 and transfer it to the first heat dissipation fins 4. The first heat dissipation fins 4 can exchange heat with the air and transfer the heat to the air, so as to achieve the purpose of heat dissipation. The setting of the heat dissipation fan 5 can accelerate the air flow and further improve the heat dissipation effect; the first heat dissipation fins 4 can transfer the heat to the water cooling component to improve the heat dissipation effect.

[0031] A plurality of second heat dissipation fins 6 are fixed on the side of the heat dissipation plate 3 away from the first heat dissipation fins 4. The second heat dissipation fins 6 penetrate through the outer wall of the box body 1 and extend into the inner cavity of the box body 1.

[0032] Specifically, the heat dissipation plate 3, the first heat dissipation fins 4 and the second heat dissipation fins 6 are integrally formed. The second heat dissipation fins 6 exchange heat with the hot air in the box body 1. The second heat dissipation fins 6 transfer the heat to the heat dissipation plate 3, and the heat dissipation plate 3 then transfers it to the first heat dissipation fins 4; the setting of a plurality of second heat dissipation fins 6 can increase the heat exchange area and improve the heat exchange efficiency.

[0033] A gasket 14 is provided between the heat dissipation plate 3 and the outer wall of the box body 1. The gasket 14 can prevent dust or humid air from entering the box body 1.

[0034] The heat dissipation plate 3 is located on the outer wall of the box body 1 away from the cover plate 2. The electrical component mounting plate 7 is arranged in parallel with the heat dissipation plate 3. There is a gap between the electrical component mounting plate 7 and the second heat dissipation fins 6; a plurality of lugs 101 are fixed on the inner wall of the box body 1, and the electrical component mounting plate 7 is fixedly connected to the lugs 101; there is a gap between the bottom end of the electrical component mounting plate 7 and the bottom wall of the inner cavity of the box body 1, and there is a gap between the top end of the electrical component mounting plate 7 and the top wall of the inner cavity of the box body 1.

[0035] Specifically, by using the law that hot air naturally rises and cold air naturally descends, the setting of the electrical component mounting plate 7 enables an air convection channel to be formed in the box body 1, so that the air in the box body 1 can all come into contact with the second heat dissipation fins 6, which is beneficial to heat transfer and improves the heat dissipation effect. The gap between the bottom end of the electrical component mounting plate 7 and the bottom wall of the inner cavity of the box body 1 is 5 to 10 centimeters, and the gap between the top end of the electrical component mounting plate 7 and the top wall of the inner cavity of the box body 1 is 5 to 10 centimeters.

[0036] The water cooling component includes a water cooling pipe 8, a liquid inlet pipe 9 and a liquid outlet pipe 10. A plurality of through holes 401 are formed in each of the first heat dissipation fins 4. The diameter of the through holes 401 matches the outer wall diameter of the water cooling pipe 8. The plurality of through holes 401 are arranged at equal intervals along the length direction of the first heat dissipation fins 4. The water cooling pipe 8 passes through the plurality of through holes 401 in a serpentine shape. One end of the liquid inlet pipe 9 is communicated with the liquid inlet end of the water cooling pipe 8, and one end of the liquid outlet pipe 10 is communicated with the liquid outlet end of the water cooling pipe 8.

[0037] Specifically, the first heat dissipation fin 4 transfers heat to the water-cooling pipe 8. The liquid inlet pipe 9 and the liquid outlet pipe 10 can be connected to a water-cooling unit arranged externally. The water-cooling unit supplies cold water to the water-cooling pipe 8 through the liquid inlet pipe 9. The water-cooling pipe 8 transfers heat to the cold water, and the cold water takes away the heat and returns to the water-cooling unit through the liquid outlet pipe 10. The water-cooling unit cools the water flowing back, and the cooled water turns back into cold water and enters the liquid inlet pipe 9, thus realizing the function of circulating water-cooling. Obviously, although the water-cooling unit has a strong cooling effect, its power consumption ability is also very strong. Therefore, other devices other than the water-cooling unit can also be used. For example, a water tank 13 is provided. The water tank 13 can be placed beside the box body 1 or fixedly connected to the box body 1. The setting method of the water tank 13 in the attached drawing is: a bracket is fixed at the bottom end of the box body 1, and the water tank 13 is placed on the bracket. A submersible pump is provided in the water tank 13. The liquid outlet end of the submersible pump is communicated with the other end of the liquid inlet pipe 9, and the other end of the liquid outlet pipe 10 is communicated with the water tank 13 and is far away from the liquid inlet end of the submersible pump. The liquid outlet pipe 10 being far away from the liquid inlet end of the submersible pump can make the water flowing into the water tank 13 not be immediately pumped into the pump head, so that it can be mixed with the water in the water tank 13. The mixed water transfers heat to the water tank 13, and the water tank 13 exchanges heat with the air, thereby reducing the water temperature. In addition, a plurality of third heat dissipation fins 15 can be arranged around the water tank 13 to enhance the heat dissipation efficiency and effect of the water tank 13. The water-cooling unit can also be used in summer, and the water tank 13 can be used in winter. The water tank 13 and the third heat dissipation fins 15 can be made of materials with high thermal conductivity such as copper, iron, and aluminum.

[0038] A plurality of first studs 301 are fixed on the side of the heat dissipation plate 3 away from the box body 1. The first studs 301 pass through the mounting holes of the heat dissipation fan 5 and are threadedly connected with first nuts 11. The air outlet end of the heat dissipation fan 5 is in contact with the first heat dissipation fin 4.

[0039] A plurality of second studs 102 are fixed on the outer wall of the box body 1. The second studs 102 penetrate through the heat dissipation plate 3 and are threadedly connected with second nuts 12.

[0040] The heat dissipation plate 3, the first heat dissipation fin 4, and the second heat dissipation fin 6 can be made of materials with high thermal conductivity such as copper, iron, and aluminum. Preferably, they are made of copper, and the thermal conductivity is better than that of iron and aluminum.

[0041] The water-cooling pipe 8, the liquid inlet pipe 9, and the liquid outlet pipe 10 can be made of materials with high thermal conductivity such as copper, iron, and aluminum. Preferably, they are made of copper, and the thermal conductivity is better than that of iron and aluminum.

[0042] The working principle of a heat dissipation distribution box of the present utility model: Utilizing the law that hot air naturally rises and cold air naturally descends, the setting of the electrical component mounting plate 7 enables an air convection channel to be formed inside the box body 1, enabling the air inside the box body 1 to come into contact with the second heat dissipation fin 6, facilitating heat transfer, and improving the heat dissipation effect.

[0043] The second heat dissipation fin 6 exchanges heat with the hot air in the box body 1. The second heat dissipation fin 6 transfers the heat to the heat dissipation plate 3, and the heat dissipation plate 3 then transfers it to the first heat dissipation fin 4. The arrangement of multiple second heat dissipation fins 6 can increase the heat exchange area and improve the heat exchange efficiency.

[0044] The first heat dissipation fin 4 can exchange heat with the air and transfer the heat to the air, so as to achieve the purpose of heat dissipation. The heat dissipation fan 5 blows air on the first heat dissipation fin 4 to accelerate the air flow and further improve the heat dissipation effect.

[0045] The first heat dissipation fin 4 transfers the heat to the water cooling pipe 8. The liquid inlet pipe 9 and the liquid outlet pipe 10 can be connected to a water cooling unit arranged outside. The water cooling unit supplies cold water to the water cooling pipe 8 through the liquid inlet pipe 9. The water cooling pipe 8 transfers the heat to the cold water, and the cold water takes away the heat and returns to the water cooling unit through the liquid outlet pipe 10. The water cooling unit cools the water flowing back, and the cooled water turns back into cold water and enters the liquid inlet pipe 9, thus realizing the function of circulating water cooling. Obviously, although the water cooling unit has a strong cooling effect, its power consumption ability is also very strong. Therefore, other devices other than the water cooling unit can also be used. For example, a water tank 13 is provided. The water tank 13 can be placed beside the box body 1 or fixedly connected to the box body 1. The arrangement method of the water tank 13 in the attached drawing is: a bracket is fixed at the bottom end of the box body 1, and the water tank 13 is placed on the bracket. A submersible pump is provided in the water tank 13. The liquid outlet end of the submersible pump is communicated with the other end of the liquid inlet pipe 9, and the other end of the liquid outlet pipe 10 is communicated with the water tank 13 and is far away from the liquid inlet end of the submersible pump. The liquid outlet pipe 10 being far away from the liquid inlet end of the submersible pump can prevent the water flowing into the water tank 13 from being immediately pumped into the pump head, so that it can be mixed with the water in the water tank 13. The mixed water transfers the heat to the water tank 13, and the water tank 13 exchanges heat with the air, thereby reducing the water temperature. In addition, a plurality of third heat dissipation fins 15 can be arranged around the water tank 13 to enhance the heat dissipation efficiency and effect of the water tank 13. It is also possible to use the water cooling unit in summer and the water tank 13 in winter.
