The utility model is further configured as follows: the side wall of the mounting piece away from the convex strip protrudes with a wave pattern.

By adopting the above technical solution, the corrugated pattern can increase the heat dissipation area of the mounting sheet, thereby improving the heat dissipation efficiency of a single mounting sheet.

The utility model is further configured as: a wave groove is provided on the side wall of the adding piece close to the convex strip.

By adopting the above technical solution, the wave groove can increase the heat dissipation area of the mounting sheet, thereby improving the heat dissipation efficiency of a single mounting sheet.

The utility model is further configured as follows: the mounting piece is located on the top of the heat dissipation fin and is fixed with an "L"-shaped anti-off cover. When the installation piece is installed, the anti-off cover and the top of the heat dissipation fin Wall, side wall fit.

By adopting the above technical solution, on the one hand, the anti-removal cover can increase the contact area between the mounting sheet and the heat dissipation fins to ensure heat conduction efficiency; on the other hand, it can improve the connection strength between the mounting sheet and the heat dissipation fins, avoiding the Shedding problem.

In summary, the utility model has the following advantages:

1. By setting the No. 1 slideway on the cooling fins and setting up the installation piece, when the heat dissipation fin is not enough to provide high-efficiency heat dissipation, you only need to install the installation piece on the radiator through the No. 1 slideway to complete the process. Double the heat dissipation area of the radiator to achieve higher heat dissipation efficiency and meet the required heat dissipation requirements;

2. By setting the anti-off cover, on the one hand, the anti-off cover can increase the contact area between the mounting sheet and the heat dissipation fin, and ensure the heat conduction efficiency; The problem of chip falling off;

3. By setting the corrugated patterns and wave grooves, the heat dissipation area of the additional fins can be increased, thereby improving the heat dissipation efficiency of a single additional fin.
