[0019] Please refer to Figures 1-5 As shown, the present utility model relates to a tightly bonded and sealed structure between a fin 1 and a heat storage plate 2 of a radiator, including the fin 1 and the heat storage plate 2 of the radiator. The heat storage plate 2 of the radiator is provided with a groove 21, and a connecting part 11 is formed at the bottom end of the fin 1. The connecting part 11 is inserted into the groove 21 so that the fin 1 is installed on the heat storage plate 2 of the radiator.

[0020] Currently, after the fin 1 on the market is installed on the heat storage plate 2 of the radiator, due to the problem of thermal expansion and contraction of the fin 1 and the heat storage plate 2 of the radiator in a high-temperature environment, the fin 1 is likely to fall off the heat storage plate 2 of the radiator.

[0021] In this embodiment, after the connecting portion 11 is inserted into the groove 21, the connecting portion 11 has a double-folded edge structure. The double-folded edge structure has a first joint surface 112, a bending surface 113, and a second joint surface 114. The fitting surface 111 is riveted to the groove through the first joint surface 112, the bending surface 113, the second joint surface 114 deformed by external force stamping. An assembly bump 22 is provided at the opening of the groove 21. When the connecting portion 11 is inserted into the groove 21, by applying pressure to the assembly bump 22, the assembly bump 22 deforms under force to form a flat surface 23. The flat surface 23 blocks the vertex of the fitting surface 111 in the double-folded edge, so that the heat sink heat storage plate 2 entirely wraps the connecting portion 11, thereby preventing the fin 1 from falling off after thermal expansion and contraction, and at the same time improving the fitting degree between the fin 1 and the heat sink heat storage plate 2.

[0022] Further, in this embodiment, the outer shape of the assembly bump 22 can be semicircular or in the shape of "M". When the assembly bump 22 is flattened into a flat surface 23, it is more evenly distributed, increasing the heat absorption area to a certain extent. The flat surface 23 will contact the connecting portion 11 of the fin 1 more tightly, thereby enhancing the stability between the fin 1 and the heat sink heat storage plate 2.

[0023] Further, in this embodiment, the bottom of the groove 21 is a U-shaped groove that fits the bent shape of the connecting portion 11 of the fin 1. Designing the groove 21 as a U-shaped groove fits the fin 1 better, so that the connection structure between the fin 1 and the heat sink heat storage plate 2 is more compact, improving the overall heat dissipation function of the heat sink.

[0024] The present utility model relates to a tightly combined structure between a fin 1 and a heat sink heat storage plate 2. When assembling the fin 1 and the heat sink heat storage plate 2, by providing an assembly bump 22 at the opening of the groove 21 of the heat sink heat storage plate 2, when the fin 1 is installed in the groove 21, the connecting portion 11 of the fin 1 has a double-folded edge structure. The connecting portion 11 is riveted tightly in the groove 21. By applying pressure to the assembly bump 22, the assembly bump 22 is deformed into a flat surface 23. The flat surface 23 blocks the fitting surface 111 of the double-folded edge, so that the fin 1 cannot break away from the heat sink heat storage plate 2 after thermal expansion and contraction. The present utility model optimizes the connection structure between the fin 1 and the heat sink heat storage plate 2, making the assembly of the fin 1 and the heat sink heat storage plate 2 convenient. After assembly, the problem of the fin 1 falling off due to thermal expansion and contraction is reduced, improving the overall heat dissipation function and durability of the heat sink.

[0025] The above embodiments are only descriptions of the preferred embodiments of the present utility model, and do not limit the scope of the present utility model. Without departing from the design spirit of the present utility model, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model shall fall within the protection scope determined by the claims of the present utility model.
