Detailed ways

In order to further understand the features and technical contents of the present utility model, please refer to the following detailed description and accompanying drawings of the present utility model. However, the accompanying drawings are provided for reference and illustration only, and are not intended to limit the present utility model.

Please refer to FIG. 1 and FIG. 2 , which are respectively a three-dimensional exploded schematic view of the utility model and an enlarged detailed view of part A of FIG. 1 . The utility model provides a forming structure of a fin and a heat dissipation base, including a heat dissipation base 1 and a plurality of fins 2; wherein:

The heat dissipation base 1 is usually made of a material with good thermal conductivity, such as aluminum or copper, which is used to be configured on a heat source (not shown) to dissipate heat, such as a central processing unit (CPU) of a computer, or Other electronic heating elements and so on. In the embodiment of the utility model, the heat dissipation base 1 is a plate-shaped body, the bottom surface of which is used to be attached to the heat source as mentioned above, and the top surface is for the vertical insertion of the above-mentioned fins 2 on it. superior. As shown in Figure 2, the heat dissipation base 1 is mainly provided with a plurality of slots 10 arranged at intervals, and a forced-in groove 11 is provided between any two slots 10, and the forced-in groove 11 can be formed by The width gradually narrows, such as a "V" shape, so that the inner wall of the embedding groove 10 can be squeezed and deformed after being forced in by a tool 3 (as shown in FIG. 3 ).

Referring to FIG. 1 again, the plurality of fins 2 can also be made of materials with good heat dissipation such as aluminum or copper, and are arranged in a sheet shape at intervals to correspond to the respective embedded grooves 10 of the above-mentioned heat dissipation base 1. , and one side edge of each fin 2 has a bezel 20 , so that the fin 2 can be vertically inserted on the heat dissipation base 1 by inserting the bezel 20 into the slot 10 .
