Annular aluminum alloy cooling fin structure

The utility model relates to the field of radiators, and particularly discloses an annular aluminum alloy radiating fin structure which comprises a radiating fin body and is characterized in that the radiating fin body is of an annular structure, a plurality of radiating fins are arranged on the outer wall of the radiating fin body, through holes are formed in the radiating fins, reinforcing rings are arranged in the through holes, and the reinforcing rings are arranged on the radiating fins. The heat dissipation performance is enhanced by arranging the heat dissipation fins, the through holes are formed in the heat dissipation fins, and the reinforcing rings are fixedly installed in the through holes, so that the strength of the heat dissipation fins is improved, and the situation that the heat dissipation performance is reduced due to the fact that the heat dissipation fins deform after collision is avoided. 本实用新型涉及散热器领域，具体公开了一种环形铝合金散热片结构,包括散热片本体，其特征在于，所述散热片本体为环形结构，所述散热片本体外壁上设置有若干散热翅片，所述散热翅片上设置有通孔，所述通孔内设置有加
