[0002] Busbar trunking is a closed metal device composed of copper or aluminum busbar columns, used to distribute large amounts of power to various components in a distributed system. It is increasingly replacing electrical wires and cables in indoor low-voltage power transmission trunk line projects. Busbar trunking generates heat during operation, especially under heavy loads. Excessive heat can affect safety. Currently, conventional busbar trunking typically uses heat-conducting plates for heat dissipation, but its heat dissipation efficiency is generally low, and its operational stability is poor. Therefore, this application proposes a safe and stable busbar trunking system. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1 to 4 This utility model discloses a safe and stable busbar trunking system, comprising a busbar trunking housing 1, with a plurality of conductive busbars 2 interspersed inside the housing 1, and an insulating layer 3 on the outer surface of the conductive busbars 2. A forced air supply mechanism 4 is fixedly installed at one end of the top of the busbar trunking housing 1, and an exhaust hood 5 is fixedly installed at the end of the busbar trunking housing 1 away from the forced air supply mechanism 4. Strip-shaped grooves 6 are formed on both sides of the busbar trunking housing 1, and a plurality of cooling fans 7 and a plurality of cooling mechanisms 8 are fixedly installed inside the strip-shaped grooves 6. The cooling mechanisms 8 are inserted through the busbar trunking housing 1 and connected to the heat exchange mechanism 8. The insulation layer 3 is bonded together. The heat dissipation mechanism 8 is composed of a copper heat-conducting limiting frame 9 and a heat pipe heat-conducting component 10. The copper heat-conducting limiting frame 9 is bonded together with the insulation layer 3. The heat pipe heat-conducting component 10 is fixedly connected to the side of the copper heat-conducting limiting frame 9 and inserted into the busbar housing 1. The heat pipe heat-conducting component 10 is composed of a heat pipe body 11, a strip aluminum heat sink 12 and a liquid absorber 13. The interior of the heat pipe body 11 is filled with evaporating liquid. The strip aluminum heat sink 12 is fixedly connected to the outer surface of the heat pipe body 11. The liquid absorber 13 is connected to the inner wall of the heat pipe body 11.

[0023] The insulation layer 3 can be made of a material with better thermal conductivity. The heat from the conductive busbar 2 is transferred to the insulation layer 3, and then to the copper thermally conductive limiting frame 9. Through the copper thermally conductive limiting frame 9, the heat is transferred to the heat pipe thermally conductive assembly 10. After the heat pipe body 11 is heated, the evaporating liquid inside it evaporates and absorbs heat. The vapor moves to the other end of the heat pipe body 11 for liquefaction and heat dissipation. The heat dissipation efficiency can be improved by the strip aluminum heat sink 12 and the cooling fan 7. The liquefied evaporating liquid flows back through the liquid wick 13, thereby forming a cycle, and thus achieving continuous heat absorption and release, improving heat dissipation efficiency.

[0024] Depend on Figures 2 to 4 As shown, the copper heat-conducting limiting bracket 9 has several heat dissipation fins 14 fixedly installed on its side, the strip aluminum heat dissipation fin 12 has several through holes 15, and the liquid absorption core 13 has a cylindrical structure.

[0025] The heat dissipation efficiency of the copper heat-conducting limiting frame 9 can be improved by the heat dissipation fins 14, and the heat dissipation efficiency of the strip aluminum heat sink 12 can be improved by the through holes 15.

[0026] Depend on Figure 1 and Figure 5 As shown, a protective mesh plate 16 is fixedly installed at the end of the exhaust hood 5 away from the busbar housing 1. The forced air supply mechanism 4 consists of an air inlet hood 17, a second protective mesh plate 18, an air filter element 19, a fan 20, and an air supply pipe 21. The air inlet hood 17 and the fan 20 are both fixedly connected to the top of the busbar housing 1. The second protective mesh plate 18 is fixedly connected to one side of the air inlet hood 17. The air filter element 19 is connected to the inside of the air inlet hood 17. The air inlet of the fan 20 is connected to the side of the air inlet hood 17 away from the second protective mesh plate 18. The air supply pipe 21 is fixedly connected between the fan 20 and the busbar housing 1 and is connected to the inside of the busbar housing 1.

[0027] The fan 20 and the air supply pipe 21 can directly supply air into the interior of the busbar trunking housing 1, so that the air inside the busbar trunking housing 1 is in a flowing state, and then exhaust air through the exhaust hood 5, thereby improving the air cooling efficiency. The air filter core 19 can filter the incoming air and prevent dust from entering the interior of the busbar trunking.

[0028] During operation, a copper thermally conductive limiting bracket is installed to limit the movement of the conductive busbar, improving its overall stability. It also provides thermal conductivity. The heat pipe thermal conductive assembly, consisting of a heat pipe body, strip-shaped aluminum heat sink, and liquid absorber, offers superior thermal conductivity, significantly improving thermal efficiency compared to traditional heat-conducting plates. A cooling fan efficiently dissipates heat from the heat pipe thermal conductive assembly. Furthermore, an exhaust hood and a forced air supply mechanism, consisting of an air inlet hood, protective mesh plate, air filter, fan, and air supply duct, force airflow into the busbar housing, increasing air circulation and thus improving air-cooling efficiency, reducing the temperature of the conductive busbar, and enhancing the safety and stability of the busbar operation.
