The base tube can be made of steel tubes, stainless steel tubes and copper tubes. The fins can also be made of steel strips, stainless steel strips, copper strips and aluminum strips.

[0003] Finned heat exchanger is mainly used for air heating in drying system and is the main equipment in hot air device. The heat medium used by the heat exchanger can be steam or hot water, or heat transfer oil. The working pressure of steam generally does not exceed 0.8Mpa, and the temperature of hot air is below 170℃.

[0004] Heat exchanger fins are a heat exchanger structure consisting of multiple layers of metal sheets. Heat exchanger fins improve the heat transfer effect of the heat exchanger by increasing the heat transfer surface area. Heat exchanger fins are usually made of aluminum because it has good thermal conductivity and corrosion resistance.

[0005] Some existing heat dissipation fins are provided with cleaning brushes when in use, but the brushes can only clean floating dust with a smaller adsorption force, but are inconvenient to clean foreign objects with a larger adsorption force.

[0006] For example, the announcement number CN208366145U discloses a heat sink fin group that is easy to clean and has strong stability. The outer surface of the heat sink fin of this patent is provided with a cleaning brush. At the same time, the brush can quickly clean the side surface of the fin, which can greatly reduce the amount of dust attached to the surface of the heat sink fin and improve the heat exchange efficiency of the heat sink fin.

[0007] This patent only provides a single brush to clean the heat sink fins. Although the brush can sweep away some floating dust from the heat sink fins, the foreign matter attached to the heat sink fins is not only floating dust. Some foreign matter with strong adsorption force adheres to the heat sink fins and is not easily brushed off by the brush. Therefore, the heat sink fins cannot be cleaned thoroughly.

[0008] Therefore, it is necessary to invent a heat exchanger fin that is easy to clean to solve the above problems. Utility Model Content
