Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to a closed bus duct which is convenient for heat dissipation. Background Art

[0002] With the emergence of modern engineering facilities and equipment, the electricity consumption of all walks of life has increased rapidly, especially with the emergence of numerous high-rise buildings and large workshops. Traditional cables as transmission conductors can no longer meet the requirements in high-current transmission systems. The parallel use of multiple cables has brought many inconveniences to on-site installation and construction. Plug-in bus ducts have emerged as a new type of distribution conductor. Compared with traditional cables, they fully demonstrate their superiority in high-current transmission. At the same time, due to the use of new technologies and new processes, the contact resistance and temperature rise of the connection points at both ends of the bus duct and the plug-in points of the branch ports are greatly reduced. High-quality insulating materials are used in the bus duct, thereby improving the safety and reliability of the bus duct and making the entire system more perfect.

[0003] The closed bus duct is a bus system composed of a metal plate as a protective shell, conductive bars, insulating materials and related accessories. However, during the installation and use of the closed bus duct, due to its large contact area, it is easy to accumulate heat, resulting in poor internal heat dissipation. In addition, the power continues to increase during use, which will cause the internal temperature of the bus duct to continue to rise. If the heat is not dissipated in time, the heat accumulation may cause a fire. The heat dissipation methods currently used for bus ducts on the market are relatively simple, and the power of the wires inside the bus duct will increase with the passage of working time, resulting in the required heat dissipation rate gradually increasing. The current heat dissipation methods cannot meet this demand. Utility Model Content

[0006] The mounting slot is provided with a plurality of mounting holes for mounting a plurality of the heat sinks, one side of the heat sink contacts the side surface of the bus duct body, and the other side contacts the heat sink, and a plurality of accommodating holes are opened on the heat sink, and fixing components are installed in the plurality of accommodating holes, and the fixing components fix the heat sink in the mounting holes.

[0007] Preferably, the fixing assembly includes a main rod, which is installed in the heat sink and leads to the top of the heat sink, and a positioning block is provided on the top of the heat sink, two fixing blocks are provided below the main rod, and an adjusting wheel is also provided above the two fixing blocks.

[0008] Preferably, the adjusting wheel and the two fixing blocks are fixed on the main rod and installed in the receiving hole accordingly, and the size of the adjusting wheel and the two fixing blocks does not exceed the size of the receiving hole.

[0009] Preferably, the plurality of mounting holes are evenly spaced and arranged on the mounting notch at the upper end, and the heat sink is fixed between the mounting notches at the upper and lower ends.

[0012] Compared with the prior art, the utility model proposes a closed bus duct that is convenient for heat dissipation and adopts the above technical solution to achieve the following technical effects:

[0013] The utility model improves the overall heat dissipation efficiency by installing heat dissipation plates on the outer sides of the side plates on both sides of the bus duct body, and then controls the overall heat dissipation demand by installing the number of heat dissipation fins. When the internal power is large and the heat generated is large, the heat dissipation rate is increased by increasing the number of heat dissipation fins, so that the internal heat is transmitted to the external heat dissipation plates more quickly. The heat dissipation fins can be fixed by simple roller adjustment. The installation process is simple and fast, and the stability is strong after the installation is completed, which prevents the external environment vibration from affecting the working efficiency of the heat dissipation fins.

[0025] In this embodiment, since the closed bus duct has a strong sealing performance and is covered with insulating material inside to prevent current leakage and short circuit, the heat generated by the internal circuit during operation is difficult to discharge or is discharged slowly. In this embodiment, a heat sink 2 is installed at the installation slot 11 set on the outside of the bus duct body 1, and the internal heat is dissipated through the aluminum alloy shell and the heat sink 2. There is still a distance between the aluminum alloy shell and the heat sink 2. Heat sink 3 is arranged in this space to increase the rate at which the internal heat is conducted to the heat sink 2. Therefore, the number of heat sinks 3 determines the heat conduction rate.

The external adjusting wheel 44 can drive the entire fixing component 4 to rotate. When the entire heat sink 3 is inserted into the mounting hole 12, the adjusting wheel 44 can be rotated to test whether the heat sink 3 is completely inserted into the mounting hole 12, and then the fixing block 43 is rotated to a position perpendicular to the mounting hole 12 to complete the fixation of the heat sink 3.
