[0003] In summary, the bus duct is not convenient for cleaning the heat sink fins. The heat sink fins of the bus duct are plugged into the bus duct. When cleaning the heat sink fins, the heat sink fins need to be removed for cleaning. After cleaning, the heat sink fins need to be installed. Generally, there are a large number of heat sink fins on the bus duct, and the workload of disassembly and assembly is extremely large, which reduces the cleaning efficiency and is inconvenient to use. It is also not convenient to maintain the cooling fan. The cooling fan on the bus duct is fixed to the top plate by screws. The cooling fan needs to be maintained during use. During maintenance, tools need to be used to disassemble and assemble it. The disassembly and assembly process is relatively troublesome, which increases the workload and reduces the efficiency of maintenance. In order to solve the above problems, we propose a bus duct with a heat dissipation structure. Utility Model Content
