Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and in particular to a bottom-mounted air-cooled radiator. Background Technology

[0002] Air-cooled heat sinks are cooling devices used to cool computer integrated circuits. They conduct heat through airflow to ensure the normal operation of hardware. Most existing air-cooled heat sinks are top-mounted snap-fit ​​structures, where the heat sink and integrated circuit board are fixed together by screws passing through the heat sink fins. This connection method requires some empty spaces on the heat sink fins for screw installation. These empty spaces increase the air resistance of the heat sink, reduce the heat dissipation area of ​​the fins, and affect the heat dissipation performance of the product. Furthermore, in top-mounted heat sinks, the screws pass through the heat sink and are threaded onto the integrated circuit board. Under actual operation, the integrated circuit board may change its contact with the bottom of the heat sink due to stress, affecting the heat dissipation performance. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a bottom-mounted air-cooled radiator that achieves bottom mounting by designing a new snap-fit ​​structure. This eliminates the need for notches in the heat dissipation fins, preserving the maximum heat dissipation area of ​​the fins, effectively reducing wind resistance, and increasing the product's heat dissipation performance.

[0004] To achieve the above objectives, this utility model provides a bottom-mounted air-cooled radiator, including a heat spreader body, a heat dissipation assembly, and multiple fastening assemblies. The heat spreader body includes an upper body and a lower body. The heat dissipation assembly includes multiple heat dissipation fins and is fixedly connected to the upper body. The fastening assemblies include rivets, studs, and a first screw. The rivets are fixedly connected to the lower body, and the studs are connected inside the rivets. The lower part of the studs is threadedly connected to the first screw, and there is a gap between the lower surface of the studs and the upper surface of the first screw.

[0005] Preferably, the fastening assembly further includes a second screw, which is movably connected between the stud and the lower body.

[0006] Preferably, the fastening assembly further includes a spring connected to the stud and located within the rivet.

[0007] Preferably, the fastening assembly further includes a first washer, which is an L-shaped washer located between the upper part of the stud and the upper part of the rivet.

[0008] Preferably, the heat spreader body has a through hole, the rivet is fixedly connected in the through hole, and the fastening assembly further includes a second washer, the second washer being an O-type washer, and the second washer being located between the second screw and the fin.

[0009] Preferably, the upper body and the lower body are fixedly connected to form a closed cavity space, and the closed cavity space is provided with a liquid medium.

[0010] Preferably, the rivets are welded to the lower body, and the heat dissipation assembly is welded to the upper body.

[0011] The beneficial effects of this utility model are as follows: The bottom-mounted air-cooled radiator provided by this utility model achieves bottom-mounted installation of the radiator through the threaded connection of the fastening component. This fastening component enables bottom-mounted installation, so that the heat dissipation fins do not need to be notched, and the maximum heat dissipation area of ​​the fins can be preserved, which can effectively reduce wind resistance and increase the heat dissipation performance of the product. By setting the gap between the lower surface of the stud and the upper surface of the first screw, the integrated circuit board and the lower body are fixed through the gap, and the gap distance can be adjusted according to the thickness of the integrated circuit board, which can accommodate more integrated circuit boards of different thicknesses, making it more adaptable. In the working state, the integrated circuit board and the heat spreader body are also more closely fitted, thereby improving the heat dissipation power of the radiator. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present invention are shown in the accompanying drawings.

[0017] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Example 1: Please refer to Figures 1 to 3 This embodiment 1 includes:

[0019] A bottom-mounted air-cooled radiator includes a heat spreader body 1, a heat dissipation assembly 2, and multiple fastening components. The heat spreader body 1 includes an upper body 11 and a lower body 12. The heat dissipation assembly 2 includes multiple heat dissipation fins 21 and is fixedly connected to the upper body 11. The fastening components include rivets 31, studs 32, and a first screw 33. The rivets 31 are fixedly connected to the lower body 12, and the studs 32 are connected inside the rivets 31. The lower part of the studs 32 is threadedly connected to the first screw 33, and there is a gap between the lower surface of the studs 32 and the upper surface of the first screw 33.

[0020] The upper body 11 and the lower body 12 are fixedly connected at their edges by welding. The heat dissipation component 2 is fixedly connected to the upper body 11 by welding. Specifically, in this embodiment, there are 4 sets of fastening components. Unlike the top-mounted heat sink, there is no need to open up the space on the heat dissipation fins 21. Therefore, it will not increase the wind resistance of the heat sink, nor will it reduce the heat dissipation area of ​​the fins. This fastening component realizes the bottom-mounted installation, so that the heat dissipation fins 21 do not need to be notched, and the maximum heat dissipation area of ​​the fins can be retained, which can effectively reduce wind resistance and increase the heat dissipation performance of the product.

[0021] Rivet 31 is fixedly connected to the lower body 12, stud 32 is connected inside rivet 31, and the lower part of stud 32 is threadedly connected to the first screw 33, thereby fixing the heat sink to the integrated circuit board. There is a gap between the lower surface of stud 32 and the upper surface of the first screw 33. The gap is used to fix the integrated circuit board to the lower body 12, and the gap distance can be adjusted according to the thickness of the integrated circuit board, which can accommodate more integrated circuit boards of different thicknesses and has stronger adaptability. In the working state, the integrated circuit board and the heat spreader body 1 are more closely fitted, thereby improving the heat dissipation power of the heat sink.

[0022] The fastening assembly also includes a second screw 34, which is movably connected between the stud 32 and the lower body 12. The engagement of the second screw 34 and the stud 32 allows for adjustment of the fit between the bottom of the lower body 12 and the integrated circuit board by adjusting the distance between the stud 32 and the lower body 12, thus broadening the range of applications.

[0023] The fastening assembly also includes a spring 35, which is connected to the stud 32 and located inside the rivet 31. In the working state, the spring 35 provides a buffer for the force on the integrated circuit board, making the force more even, thereby making the bottom of the heat sink fit better with the integrated circuit board and the heat dissipation effect better.

[0024] The fastening assembly also includes a first washer 36, which is an L-shaped washer located between the upper part of the stud 32 and the upper part of the rivet 31. The first washer 36 buffers the force between the stud 32 and the rivet 31, improving the fit between the integrated circuit board and the heat sink during operation.

[0025] The heat spreader body 1 has a through hole, and the rivet 31 is fixedly connected in the through hole. The fastening assembly also includes a second washer 37, which is an O-ring washer, and is located between the second screw 34 and the fin 21. The second washer 37 provides cushioning between the second screw 34 and the fin 21.

[0026] The upper body 11 and the lower body 12 are fixedly connected to form a closed cavity space 13. The closed cavity space 13 contains a liquid medium. The heat spreader transfers the heat generated on the integrated circuit board to the heat dissipation component 2 through the phase change of the liquid medium. The heat is then transferred out through the heat dissipation fins 21, thereby realizing the heat dissipation of the heat sink.

[0027] Rivet 31 is welded to the lower body 12, and heat dissipation component 2 is welded to the upper body 11.

[0028] The bottom-mounted air-cooled radiator provided by this utility model achieves bottom-mounted installation through the threaded connection of the fastening assembly. This fastening assembly enables bottom-mounted installation, eliminating the need for notches in the heat dissipation fins and preserving the maximum heat dissipation area of ​​the fins. This effectively reduces wind resistance and increases the product's heat dissipation performance. By setting a gap between the lower surface of the stud and the upper surface of the first screw, the integrated circuit board and the lower body are fixed through the gap. The gap distance can be adjusted according to the thickness of the integrated circuit board, which can accommodate more integrated circuit boards of different thicknesses, thus increasing its adaptability. In the working state, the integrated circuit board and the heat spreader body are also more closely fitted, thereby improving the heat dissipation power of the radiator.

[0029] Those skilled in the art should understand that the above embodiments are merely for clearly illustrating the present invention and are not intended to limit the scope of the present invention. For those skilled in the art, other changes or modifications can be made based on the above-described invention, and these changes or modifications still fall within the scope of the present invention.
