Description

Technical Field

[0001] The utility model belongs to the technical field of heat dissipation fins, and in particular relates to a combined engine heat dissipation fin. Background Art

[0002] Heat sink fins are common thermal management components in electronic and mechanical equipment. Their main function is to improve heat dissipation efficiency and reduce equipment temperature, thereby ensuring the normal operation of the equipment and extending its service life. The working principle of heat sink fins is based on increasing the surface area to promote heat conduction and convection heat dissipation. The heat sink fins increase the surface contact area with the air to accelerate the dissipation of heat from the heat source to the surrounding environment. Fins are usually installed on the engine so that the engine can effectively dissipate heat, thereby improving the engine's operating efficiency.

[0003] Among the cooling fins currently in use, it may not be possible to remove the densely packed fins well during maintenance and replacement, which increases the difficulty of maintenance and may damage other fins, increasing maintenance costs. It also increases maintenance time, reduces work efficiency, and is inconvenient for daily maintenance and replacement work. Therefore, a combined engine cooling fin is proposed.
