Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat sink fin folding technology, and in particular to a heat sink fin edge folding and deformation-preventing reinforcement structure. Background Technology
[0002] Heat sinks are commonly used heat dissipation components in electronic devices, increasing heat dissipation efficiency by increasing surface area. Due to prolonged use and external factors (such as vibration and temperature differences), heat sinks may experience edge deformation, which affects their heat dissipation performance. To enhance the deformation resistance of heat sinks, an edge-folding reinforcement structure is employed. This reinforcement structure typically involves folding the edges of the heat sink fins to form a strengthened physical barrier, effectively preventing edge deformation under high temperature and high pressure conditions.
[0003] The principle behind edge folding is to alter the shape of the heat dissipation fins, making their edges more robust and resistant to external forces. Specifically, the folded edges increase local rigidity, preventing bending or twisting of the fin edges under external environmental influences. This structure can increase compressive and tensile strength by thickening the edges or bending them, maintaining the stability and long-term heat dissipation effect of the heat dissipation fins. However, bending the heat dissipation fins can easily lead to displacement, affecting the bending effect. Therefore, this heat dissipation fin edge folding anti-deformation reinforcement structure is proposed to solve the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a heat dissipation fin edge folding anti-deformation reinforcement structure, including a workbench 1, a placement platform 2 fixedly connected to the upper part of the workbench 1, and support plates 10 fixedly connected to the upper left and right sides of the workbench 1. The support plates 10 have sliding grooves 13 on the front and rear sides inside, and a rack 12 is slidably connected inside the sliding grooves 13. An electric push rod 11 is fixedly connected to the upper part of the rear rack 12. A gear 14 is meshed with the rack 12. A rotating rod 15 is fixedly connected to the side of the gear 14 that is close to it. A moving plate 16 is rotatably connected to the end of the rotating rod 15 that is close to it. An adjusting rod 17 is threadedly connected inside the moving plate 16. A pressure block 18 is rotatably connected to the outside of the end of the adjusting rod 17 that is close to it. The gear 14 is rotatably connected inside the support plate 10.
[0028] A support frame 3 is fixedly connected to the upper rear side of the workbench 1. Motors 4 are installed on both the left and right sides of the front side of the crossbeam of the support frame 3. A screw 5 is fixedly connected to the output end of the motor 4. A mounting frame 6 is slidably connected to the outside of the screw 5. A lifting device 8 is fixedly connected to the front side of the mounting frame 6. A pressure roller 9 is installed at the bottom of the movable frame that is threaded to the outside of the lifting device 8. Guide rails 7 are fixedly connected to the upper and lower sides of the front side of the crossbeam of the support frame 3. The lifting device 8 is slidably connected to the outside of the guide rails 7.
[0029] By placing the heat dissipation fins on the placement platform 2, and then activating the electric actuator 11, the rack 12 is pushed, causing the gear 14 to rotate through its meshing connection with the rack 12. Simultaneously, the rack 12 on the other side is moved. As the gear 14 rotates, the rotating rod 15 rotates inside the moving plate 16, causing the moving plate 16 to move. This causes the pressure block 18 to move under the rotation of the gear 14, performing an upward or downward operation to position the heat dissipation fins and prevent them from moving. This achieves the positioning of the heat dissipation fins and prevents them from moving during folding, which would affect the folding effect and quality. After adjusting the bending position, the motor 4 is activated, causing the screw 5 to rotate and move the mounting bracket 6, which then slides synchronously outside the guide rail 7. This ensures the smooth movement of the lifting device 8. Simultaneously, the lifting device 8 is activated, causing the pressure roller 9 to move downward and fold the edge of the heat dissipation fins.
[0030] Reference Figure 1 and Figure 3 A mounting plate 19 is fixedly connected to the top of the inner wall of the workbench 1. Two cylinders 20 are fixedly connected to the left and right sides of the mounting plate 19. A connecting plate 21 is fixedly connected to the output end of the cylinders 20. A limiting plate 22 is fixedly connected to the upper part of the connecting plate 21. A through groove 23 is opened on the left and right sides of the upper inner side of the workbench 1. The limiting plate 22 is slidably connected to the inside of the through groove 23. A sliding rod 24 is fixedly connected to the front and back of the inner wall of the workbench 1. The limiting plate 22 is slidably connected to the outside of the sliding rod 24.
[0031] Then, the cylinder 20 is started, which drives the limiting plate 22 through the connecting plate 21, so that it slides inside the through groove 23 and simultaneously slides outside the slide rod 24. This ensures the stability of the limiting plate 22 during movement, realizes the adjustment of the bending position of the heat dissipation fins, and ensures the stability and reliability of the operation, ensuring that the bending angle is the required value.
[0032] Working principle: When the device is needed, the heat sink fins are placed on the placement platform 2, and then the electric actuator 11 is activated to push the rack 12, so that the gear 14 rotates by meshing with the rack 12. At the same time, the rack 12 on the other side moves, causing the rotating rod 15 to rotate, which in turn drives the moving plate 16 and the pressure block 18 to move, thereby positioning and fixing the heat sink fins and preventing them from moving. The cylinder 20 is activated, and the connecting plate 21 drives the limiting plate 22 to slide between the through groove 23 and the slide rod 24, ensuring the stability of the limiting plate 22 when it moves. The motor 4 is activated to drive the screw 5 to rotate, so that the mounting bracket 6 slides along the guide rail 7, ensuring the stability of the movement of the lifting device 8. At the same time, when the lifting device 8 moves, the lifting device 8 is activated to drive the pressure roller 9 to move down, performing an edge folding operation on the heat sink fins.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
