Description

Technical Field

[0001] The utility model relates to the technical field of wire trough heat dissipation, in particular to a bus trough with heat dissipation function. Background Art

[0002] The bus duct is a closed metal device composed of copper and aluminum busbars. It is a device responsible for transmitting and distributing electric energy in the low-voltage power supply system. It has many advantages such as large current carrying capacity, high protection level, convenient distribution of electric energy, compact structure, easy installation and maintenance, and long service life. The conductors in the bus duct are wrapped with insulating heat-conducting materials, which will generate a lot of heat after working for a long time.

[0003] In the utility model with application number 202222501733.6, a heat dissipation type bus duct is disclosed. Heat dissipation fins are arranged on the upper, lower, left and right sides thereof. Since the total area of ​​the heat dissipation fins in contact with the air is much larger than the area of ​​the outer surface of the bus duct body, the heat dissipation fins can improve the heat dissipation effect, thereby preventing the bus duct body from overheating and affecting its conductive performance and service life. The first heat dissipation fins and the second heat dissipation fins can be filled with thermal oil. Compared with the heat dissipation fins made of metal, the thermal conductivity of the thermal oil is higher. The heat dissipation fins filled with thermal oil can It is applied to bus ducts with higher power and effectively dissipates heat therefrom. A plurality of cooling fans are fixedly installed above the first cooling fin assembly or the second cooling fin assembly. The airflow generated by the cooling fan can flow in the gap between the first cooling fin or the second cooling fin. In most cases, the bus duct is installed in a closed room with low air flow. Even if a cooling fin assembly is provided on the side of the bus duct body, only a part of the heat dissipation area can be increased. It is also necessary to increase the gas flow in the gap between the first cooling fin or the second cooling fin to further improve the heat dissipation effect.

[0004] However, in the above-mentioned heat dissipation type bus duct, the first heat dissipation fin assembly and the second heat dissipation fin assembly are both fitted with the outer side of the bus duct body, and can only absorb the heat emitted from the outer shell of the bus duct body. The heat generated by the cable cannot be quickly transferred to the bus duct body, so that there is still heat in the cable, resulting in low heat dissipation efficiency. In order to ensure the heat dissipation efficiency, the first heat dissipation fin assembly and the second heat dissipation fin assembly in the above-mentioned heat dissipation type bus duct have wrinkles on the surface. After long-term use, a large amount of dust will fall and affect the heat dissipation effect. It is difficult for personnel to directly climb up to clean it. Therefore, the utility model proposes a bus duct with heat dissipation function to solve the problems existing in the prior art. Utility Model Content

The bus duct shell 1 is symmetrically provided with a heat dissipation mechanism. When the cables in the bus duct are energized and heated, the heat is transferred to the annular heat pipe 4 through the thermal conductive gel 3 wrapped around the cables, and then transferred to the heat spreader 5 and the bus duct shell 1. The large surface area of ​​the heat dissipation fins 15 is utilized to achieve rapid heat dissipation, which facilitates rapid outward transfer of heat. This solves the problem that the heat dissipation fins 15 can only absorb heat on the bus duct body, and the heat generated by the cables cannot be quickly transferred to the bus duct body for heat dissipation, thereby effectively improving the heat dissipation efficiency.
