[0017] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0018] like Figures 1 to 4 As shown, in this embodiment, a radiator fin structure includes a plurality of fins 1 and a plurality of aluminum plates 2, wherein the plurality of fins 1 are stacked in a vertical direction, an aluminum plate 2 is arranged between each of the two fins 1, a first connecting hole is arranged on the fin 1, a hole edge 3 is arranged at the edge of the first connecting hole, a second connecting hole 4 is arranged on the aluminum plate 2, the hole edge 3 is inserted into the second connecting hole 4, and an end portion of the hole edge 3 is bent outward and pressed against the inner wall of the second connecting hole 4 to form a riveted structure 5.

[0019] The fins 1 and the aluminum plates 2 are stacked together at intervals, and the hole edge 3 of the first connecting hole is inserted into the second connecting hole 4. During the stacking process, the upper end of the hole edge 3 is bent by riveting of the mold part 10. During the outward bending process, not only is there no gap between the aluminum plate 2 and the fins 1, but the hole edge 3 is pressed tightly in the second connecting hole 4 to form a riveted joint, which reduces the difficulty of subsequent electroplating and improves the conductive performance.

[0020] In terms of specific structure, it also includes two iron plates 6, a screw rod 7 and a nut 8. The two iron plates 6 are respectively located on the uppermost fin 1 and the lowermost fin 1. The screw rod 7 passes through the uppermost iron plate 6, a plurality of first connecting holes, a plurality of second connecting holes 4 and the lowermost iron plate 6 and is threadedly connected with the nut 8. A washer 9 is arranged between the nut 8 and the iron plate 6, and the screw rod 7 passes through the washer 9.

[0021] After stacking the fins 1 and the aluminum plate 2, place an iron plate 6 on the uppermost fin 1, and place another iron plate 6 on the lowermost fin 1. The screw 7 passes through the uppermost iron plate 6 from top to bottom, passes through a plurality of first connecting holes and a second connecting hole 4, and then passes out from the lowermost iron plate 6. The screw 7 is locked with a nut 8 to ensure that the fin 1 and the aluminum plate 2 form a stable structure. In addition, with the protection of the washer 9, the nut 8 will not be directly pressed on the iron plate 6, and the subsequent electroplating defective rate is reduced from the current 12% to 1%.

[0022] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present utility model and the technical principles used. Within the technical scope disclosed by the present utility model, any changes or substitutions that can be easily thought of by technicians familiar with this technical field should be included in the protection scope of the present utility model.
