[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1

[0022] like Figures 1 to 4 As shown, a specific embodiment of the air-cooled radiator fin rapid extrusion installation mechanism of this utility model includes:

[0023] Fin structure: The heat dissipation fins 3 are connected to the substrate 1 through the fin connecting part 2 below. A locking block 4 is provided on the bottom surface of the fin connecting part 2. A hook 5 is installed on the side of the locking block 4. The lower end of the hook 5 is fixedly connected to the locking block 4, and the upper end is inclined to the outside. An avoidance groove 6 is provided between the upper end of the hook 5 and the locking block 4. The avoidance groove 6 is used to provide space for the elastic deformation of the hook 5 during assembly.

[0024] Preferably, three equidistant locking blocks 4 are provided on the bottom surface of the fin connecting part 2, and two locking hooks 5 are provided symmetrically on the left and right sides of the locking block 4; a frustum-shaped connecting part 9 is provided at the bottom of the locking block 4, the frustum-shaped connecting part 9 is an inverted frustum-shaped structure, which is convenient for assembly with the mounting groove 7, and the locking block 4 is made of aluminum alloy.

[0025] Substrate 1 structure: The upper surface of substrate 1 is provided with a mounting groove 7 corresponding to the card block 4. The card block 4 is inserted into the mounting groove 7. The side of the mounting groove 7 is provided with a fixing groove 8 corresponding to the hook 5. The fixing groove 8 is an inverted triangular structure. The hook 5 is installed in the fixing groove 8. The mounting groove 7 and the card block 4 are installed with an interference fit.

[0026] Example 2

[0027] The difference between this embodiment and Embodiment 1 is that:

[0028] Fin design: The bottom of the heat dissipation fin 3 has six locking blocks 4, which are inverted trapezoidal in shape and made of copper alloy. The structure of this embodiment is not shown in the figure.

[0029] The working principle of this utility model is as follows: During installation, the locking block 4 of the heat dissipation fin 3 is aligned with the mounting groove 7 on the substrate 1. The locking block 4 is inserted into the mounting groove 7 by pressing. Since there is an avoidance groove 6 between the hook 5 and the locking block 4, the hook 5 undergoes elastic deformation due to the pressure from the side of the mounting groove 7 during the pressing process. After entering the mounting groove 7, the hook 5 is aligned with the fixing groove 8 and returns to its original shape. The upper end of the hook 5 is inserted into the fixing groove 8 with the inverted triangular structure, thus realizing a firm connection between the heat dissipation fin 3 and the substrate 1.

[0030] During mass production, automated extrusion equipment is used to quickly install the manufactured heat dissipation fins 3 onto the substrate 1. By adjusting the pressure of the extrusion equipment, the firmness and consistency of each fin installation are ensured.

[0031] All components mentioned in this article are general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods, so they will not be described in detail here.

[0032] While the specific embodiments of this utility model have been described in detail above, this utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model. Modifications or variations that do not involve creative labor are still within the protection scope of this utility model.
