Riveting apparatus for thin heat sink fin and thin cover plate

A riveting structure for a thin heat sink fin and a thin cover plate, comprising a plurality of thin heat sink fins and a thin cover plate;

• the plurality of thin heat sink fins being vertically disposed, the thin cover plate being disposed on top of the thin heat sink fins;
• each of the thin heat sink fins having a raised portion extending from a top thereof;
• the thin cover plate being formed with a plurality of cover plate riveting holes, the raised portion of each thin heat sink fin passing through a corresponding one of the cover plate riveting holes to extend upward, the raised portion of each thin heat sink fin being pressed and deformed by a rolling device in a rolling manner to fill a space in the corresponding cover plate riveting hole, so as to be riveted and fixed to the corresponding cover plate riveting hole, the raised portion after being pressed being flush with a surface of the thin cover plate.
