[0002] In today's rapidly developing technological world, the operating power of electronic components is increasing, and the heat generated is also increasing. Natural heat dissipation can no longer meet the needs of modern electronic components, and heat sinks, as a device to assist in the heat dissipation of electronic components, are receiving more and more attention.

[0003] Heat sinks take different forms depending on the electronic device. One type, the pinned heat sink, is highly valued for its application in high-tech electronic devices such as CPUs and LEDs. Most existing pinned heat sinks are manufactured by directly milling them into aluminum, making the heat sink and heat plate a single unit. This means that if one heat sink is damaged later, the entire unit needs to be replaced, increasing the cost of use. Therefore, a pinned, assembled heat sink is designed to overcome these technical shortcomings. Utility Model Content

[0024] This specific embodiment is an assembled heat sink with pins, and its structural schematic diagram is shown below. Figures 1-5 As shown, the device includes a heat sink 1. A first mounting groove 2 and two second mounting grooves 3 are formed in the middle of the upper surface of the heat sink 1. A third mounting groove 4 is formed at the left end of the lower surface of the heat sink 1. A second heat dissipation component 6 is installed inside the first mounting groove 2. First heat dissipation components 5 are installed inside each of the two second mounting grooves 3. A third heat dissipation component 7 is installed inside the third mounting groove 4. Pins 11 are installed on the front of each of the two first heat dissipation components 5. Limiting components 13 are provided in the middle of the inner walls of the first mounting groove 2, the two second mounting grooves 3, and the third mounting groove 4. By installing the two first heat dissipation components 5 in their corresponding second mounting grooves 3, the second heat dissipation component 6 in the first mounting groove 2, and the third heat dissipation component 7 in the third mounting groove 4, and pressing them down, the corresponding limiting components 13 can lock and limit the corresponding heat dissipation components, achieving modular installation. Simultaneously, when a heat sink 9 on a heat dissipation component is damaged, the corresponding connecting plate 8 can be pulled to drive the limiting components 13 to unlock, thereby removing the connecting plate 8 and the damaged heat sink 9 for replacement.

[0025] Among them, the two second mounting slots 3 are of equal size, the third mounting slot 4 is larger than the second mounting slot 3, and the first mounting slot 2 is larger than the third mounting slot 4; the size and position of the first mounting slot 2, the second mounting slot 3 and the third mounting slot 4 are not limited to those described above, and can be set as needed, so that the heat dissipation component can be modularized, making it easy to install and replace.

[0026] In addition, the first heat dissipation component 5, the second heat dissipation component 6 and the third heat dissipation component 7 all include a connecting plate 8 and multiple heat sinks 9. The multiple heat sinks 9 are arranged at equal intervals and fixedly connected to the upper surface of the connecting plate 8. The four connecting plates 8 are different in size, and the heat sinks 9 on each connecting plate 8 are different in number.

[0027] In addition, each connecting plate 8 has a clearance 19 at the bottom center of both ends, and a second inclined surface 20 is provided at the bottom of the inner wall of the clearance 19. A limit groove 21 is provided in the middle of the inner wall of the clearance 19. This setting can be used in conjunction with the limit component 13 to lock and limit the connecting plate 8 during installation, and at the same time, it is convenient to drive the limit component 13 to be passively unlocked during disassembly.

[0028] In addition, the limiting component 13 includes a mounting frame 14. A round rod 15 is fixedly connected to the middle of the inner wall of the mounting frame 14. A limiting block 16, which is slidably connected to the mounting frame 14, is sleeved on the other end of the round rod 15. A return spring 24 is fixedly connected between the limiting block 16 and the inner wall of the mounting frame 14. The return spring 24 is located outside the round rod 15. The mounting position of the mounting frame 14 is such that a groove is provided in the middle of the inner wall on both sides of each mounting slot. The groove is rectangular and can integrate the round rod 15, the limiting block 16 and the return spring 24 inside the mounting frame 14 to form a modular installation, which is convenient for later assembly. In this way, when the limiting block 16 is subjected to external pressure, it can slide into the mounting frame 14 and compress the return spring 24. The return spring 24 can push the limiting block 16 to always be exposed outside the mounting frame 14 when there is no external force.

[0029] Furthermore, a circular hole 17 is provided in the middle of the limiting block 16, and the other end of the circular rod 15 is slidably connected to the inside of the circular hole 17. The end of the limiting block 16 near the return spring 24 is always located inside the mounting frame 14, and the end of the limiting block 16 away from the return spring 24 is adapted to the limiting groove 21. The top and bottom of the end of the limiting block 16 away from the return spring 24 are provided with a first inclined surface 18 that is slidably connected to the second inclined surface 20. The end of the limiting block 16 away from the return spring 24 is slidably connected to the inside of the limiting groove 21; through the circular rod 15 The sliding fit with the circular hole 17 can improve the stability of the movement of the limiting block 16. When the connecting plate 8 is installed in the corresponding mounting groove, the second inclined surface 20 can press a first inclined surface 18 on the limiting block 16, so that the first inclined surface 18 can slide on the second inclined surface 20 after being subjected to force and move into the mounting frame 14 and compress the return spring 24. When the connecting plate 8 contacts the inner wall of the mounting groove, the return spring 24 is reset. At this time, the limiting block 16 can be reset and enter the limiting groove 21. At the same time, a "click" sound will be heard, indicating that the connecting plate 8 is locked.

[0030] In addition, mounting parts are fixedly connected between two adjacent heat sinks 9 on the two first heat dissipation components 5 and at positions corresponding to pins 11. A mounting hole is opened in the middle of the front of the mounting part, and three annular grooves with equal spacing are opened on the inner wall of the mounting hole. A positioning ring 22 is fitted in the middle of the pin 11. Three annular rings 23 that are adapted to the annular grooves are fitted on the outside of the pin 11 and behind the positioning ring 22. The rear end of the pin 11 is inserted into the interior of the mounting hole. The positioning ring 22 is in contact with the front of the mounting part. The cross section of the annular ring 23 is a right triangle. The annular ring 23 is engaged in the interior of the corresponding annular groove. The annular ring 23 can be metal or plastic with a certain deformation capability. The rear end of the pin 11 is chamfered. The rear end of the pin 11 can be aligned with the mounting hole and forcefully inserted to cause the annular ring 23 to deform to a certain extent and engage in the outermost annular groove. Continuous force can make the rearmost annular ring 23 engage in the innermost annular groove.

[0031] In addition, keyways 10 are provided at the middle of the front and rear ends of the bottom wall of the first mounting groove 2, the middle of the front and rear ends of the bottom wall of the two second mounting grooves 3, and the middle of the front and rear ends of the top wall of the third mounting groove 4. A positioning block 12 adapted to the keyway 10 is fixedly connected to one side of the connecting plate 8. The positioning block 12 is slidably connected inside the keyway 10. By inserting the positioning block 12 into the corresponding keyway 10, the connecting plate 8 can be installed quickly, and the stability of the connecting plate 8 installation is increased.

[0032] Working principle: In use, firstly, align the rear end of pin 11 with the mounting hole and insert it forcefully, causing the annular ring 23 to deform and engage in the outermost annular groove. Continuing to apply force will cause the rearmost annular ring 23 to engage in the innermost annular groove, thus installing pin 11 onto the mounting part. Then, by installing two first heat dissipation components 5 into the corresponding second mounting grooves 3, the second heat dissipation component 6 into the first mounting groove 2, and the third heat dissipation component 7 into the third mounting groove 4 and pressing them down, the second inclined surface 20 can compress one of the first inclined surfaces 1 on the limiting block 16. 8. After the first inclined surface 18 is subjected to force, it can slide on the second inclined surface 20 and move into the mounting frame 14, compressing the return spring 24. When the connecting plate 8 contacts the inner wall of the mounting groove, the return spring 24 resets. At this time, the limit block 16 can reset and enter the limit groove 21, and a "click" sound will be heard, indicating that the connecting plate 8 is locked and installed. When the damaged heat sink 9 is removed, simply lift the corresponding connecting plate 8 to make the inner wall of the limit groove 21 apply force to the other first inclined surface 18, so that the limit block 16 moves towards the mounting frame 14, thereby allowing the connecting plate 8 to disengage from the corresponding mounting groove.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
