Description

Technical Field

[0001] This utility model relates to the field of fin assembly technology, and in particular to a heat dissipation fin assembly that is easy to assemble. Background Technology

[0002] With the development of electronic technology, the transistor density of various chips is increasing day by day. In order to ensure the stable operation of the central processing unit, a high-efficiency heat sink has become an inevitable requirement. The most common and effective method is to use a fan to drive airflow and exchange heat with the heat sink fin assembly to remove the heat from the heat sink fins and achieve the purpose of cooling. The heat sink fin assembly is composed of multiple heat sink fins.

[0003] Existing technologies often use direct front-to-back snap-fit ​​connections between adjacent heat dissipation fins. This connection structure requires high stamping precision for the heat dissipation fins, has low stamping efficiency, and is not very stable along the direction perpendicular to the installation after installation.

[0004] The existing patent (publication number: CN212629046U) discloses a heat dissipation fin assembly that is easy to stamp and assemble, belonging to the field of heat dissipation technology. This utility model consists of several parallel heat dissipation fins that are sequentially fastened together. Each heat dissipation fin is composed of a front side, a rear side, and a central plane. The height of the rear side is lower than that of the front side. The front side and the rear side have clips extending away from the central plane for locking. The central plane has hooks extending towards the slot. There is a slot between the clips and the central plane for accommodating the hooks and clips. In use, the hooks of the upper-level heat dissipation fins are first inserted into the slots, and then the clips of the lower-level heat dissipation fins are inserted into the slots, thereby locking the hooks of the upper-level heat dissipation fins in the slots, ultimately forming a stable three-dimensional locking structure.

[0005] To address the aforementioned issues, existing patents offer solutions, but they lack a modular structure for assembling individual heat sink fins. This prevents flexible adjustments to the number and combination of heat sink fins based on actual needs. Consequently, when adjustments to heat dissipation performance are required, it is impossible to quickly and easily increase or decrease the number of heat sink fins, thus reducing work efficiency.

[0006] To address this, a heat dissipation fin assembly that is easy to assemble is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a heat dissipation fin assembly that is easy to assemble. This solves the problem that existing fin assemblies lack a modular structure for installing individual heat dissipation fins, which prevents flexible adjustment of the number and combination of heat dissipation fins according to actual needs. When heat dissipation performance needs to be adjusted, it is not possible to quickly and conveniently increase or decrease the number of heat dissipation fins, thereby reducing work efficiency.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation fin assembly that is easy to assemble, comprising a heat dissipation fin body, wherein a module mechanism is snapped into the bottom of the heat dissipation fin body, and the bottom of the module mechanism is slidably connected to the inner side of a limiting mechanism.

[0009] The module mechanism includes several limiting modules, fixing holes, several moving modules, limiting blocks, connecting holes, and snap-fit ​​holes. The fixing holes are fixedly connected to the top of the limiting modules, and the inner side of the fixing holes snaps into the bottom of the heat sink fin body. The limiting blocks are fixedly connected to the inner side of the moving modules, and the limiting modules snap onto the surface of the limiting blocks. The connecting holes are opened on both sides of the moving modules and are slidably connected to the surface of the limiting mechanism. The snap-fit ​​holes are opened at the bottom of the moving modules.

[0010] Preferably, the limiting mechanism includes a connecting plate, two support rods, a pressure spring, a baffle, several locking blocks, and two connecting rods, with the two support rods fixedly connected to both sides of the rear side of the connecting plate.

[0011] Preferably, the pressure spring is sleeved on the surface of the support rod, the baffle is fixedly connected to the top of the pressure spring, and several snap-fit ​​blocks are fixedly connected to the inner side of the connecting plate.

[0012] Preferably, the connecting rod is slidably connected to the surface of the support rod, the surface of the connecting rod is slidably connected to the connecting hole, and a plurality of snap-fit ​​blocks snap into the inner side of the snap-fit ​​hole.

[0013] Preferably, torsion springs are fixedly connected to both sides of the front side of the connecting plate, and a baffle is fixedly connected to the front side of the torsion springs.

[0014] Preferably, a reinforcing ring is fixedly connected to the bottom of the support rod, and the surface of the reinforcing ring is coated with an anti-corrosion coating.

[0015] Preferably, a protective pad is provided on the surface of the snap-fit ​​block, the surface of the protective pad is engraved with anti-slip texture, and the surface of the protective pad is in contact with the inner side of the snap-fit ​​hole.

[0016] Preferably, a protective sleeve is fitted on the surface of the limiting block, the surface of the protective sleeve is engraved with anti-slip texture, and the surface of the protective sleeve is in contact with the inner side of the limiting module.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The modular mechanism of this application consists of several limiting modules and moving modules. It is connected to the heat dissipation fin body through fixing holes, which makes the installation and disassembly of the heat dissipation fins more convenient. Different numbers of limiting modules and moving modules can be selected and combined according to actual needs to meet the heat dissipation requirements of different specifications. The snap-fit ​​hole at the bottom of the moving module can be snapped with the snap-fit ​​block of the limiting mechanism, which further enhances the connection stability between the modular mechanism and the limiting mechanism. This snap-fit ​​method enables the heat dissipation fin assembly to withstand certain vibrations and external forces during use and is not easy to fall apart.

[0019] 2. The two support rods on the rear side of the limiting mechanism connecting plate of this application provide stable support for the entire heat dissipation fin assembly. The support rods can withstand the weight of the heat dissipation fin assembly and the external forces that may be encountered during use, ensuring that the heat dissipation fin assembly is installed firmly and reliably. The pressure spring and baffle sleeved on the surface of the support rod can play a buffering role during installation. When the module mechanism is connected to the limiting mechanism, the pressure spring can absorb some of the impact force to prevent damage to the heat dissipation fins or connecting parts due to excessive force. At the same time, the pressure spring can also provide a certain preload to make the connection tighter. The connecting rod is slidably connected to the surface of the support rod and slidably connected to the connecting holes on both sides of the moving module, providing a guiding role for the installation of the module mechanism. This sliding connection method allows the module mechanism to be installed more accurately on the limiting mechanism, improving installation efficiency and accuracy. Attached Figure Description

[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] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A heat dissipation fin assembly that is easy to assemble includes a heat dissipation fin body 1, a module mechanism 2 that is snapped into the bottom of the heat dissipation fin body 1, and the bottom of the module mechanism 2 that is slidably connected to the inside of the limiting mechanism 3.

[0029] The module mechanism 2 includes several limiting modules 21, fixing holes 22, several moving modules 23, limiting blocks 24, connecting holes 25, and snap-fit ​​holes 26. The fixing holes 22 are fixedly connected to the top of the limiting modules 21, and the inner side of the fixing holes 22 is snap-fitted to the bottom of the heat sink body 1. The limiting blocks 24 are fixedly connected to the inner side of the moving modules 23, and the limiting modules 21 are snap-fitted to the surface of the limiting blocks 24. The connecting holes 25 are opened on both sides of the moving modules 23 and are slidably connected to the surface of the limiting mechanism 3. The snap-fit ​​holes 26 are opened at the bottom of the moving modules 23.

[0030] In this embodiment: by setting the heat dissipation fin body 1 as the main component for heat dissipation, and connecting it with the module mechanism 2, the functions of easy assembly and flexible adjustment are realized. Its snap-fit ​​connection with the fixing hole 22 makes installation and disassembly more convenient. Users can quickly replace or adjust the number and layout of the heat dissipation fins according to actual needs, improving the adaptability and maintainability of the heat dissipation system. The limiting module 21, by snapping onto the surface of the limiting block 24, provides additional support and limiting for the heat dissipation fin body 1. This connection method ensures that the heat dissipation fin body 1 maintains a stable position during assembly, preventing tilting or displacement. Furthermore, the combination of multiple limiting modules 21 can adjust the layout and spacing of the heat dissipation fins according to actual needs, improving the heat dissipation effect. The fixing hole 22 is fixedly connected to the top of the limiting module 21, providing a stable snap-fit ​​position for the heat dissipation fin body 1. This snap-fit ​​method is simple and reliable, ensuring that the heat dissipation fin body 1 will not easily fall off during use. At the same time, the design of the fixing hole 22 makes the installation direction of the heat dissipation fin body 1 clear, facilitating quick assembly by the user. The moving module 2... As the intermediate component connecting the heat sink fin body 1 and the limiting mechanism 3, component 3 plays a crucial role. The sliding connection between the connecting holes 25 on both sides and the connecting rod 36 allows the moving module 23 to move smoothly on the limiting mechanism 3, facilitating user assembly and adjustment. Simultaneously, the snap-fit ​​design between the snap-fit ​​hole 26 at the bottom of the moving module 23 and the snap-fit ​​block 35 ensures the stability and reliability of the heat sink assembly during use. The limiting block 24 is fixedly connected to the inside of the moving module 23, providing an accurate snap-fit ​​position for the limiting module 21. The connecting hole 2... The 5 is located on both sides of the moving module 23, and its sliding connection with the connecting rod 36 provides guidance for the movement of the moving module 23. This connection method allows the moving module 23 to maintain linear movement during assembly and adjustment, avoiding offset or jamming. The snap-fit ​​hole 26 is located at the bottom of the moving module 23, and its snap-fit ​​design with the snap-fit ​​block 35 allows the moving module 23 to be firmly fixed on the limiting mechanism 3, facilitating user assembly and disassembly. The tight fit with the snap-fit ​​block 35 ensures the stability and reliability of the heat dissipation fin assembly during use.

[0031] Specifically, such as Figure 3 As shown, the limiting mechanism 3 includes a connecting plate 31, two support rods 32, a pressure spring 33, a baffle 34, several locking blocks 35 and two connecting rods 36. The two support rods 32 are fixedly connected to the two sides of the rear side of the connecting plate 31.

[0032] Specifically, such as Figure 3 As shown, the pressure spring 33 is sleeved on the surface of the support rod 32, the baffle 34 is fixedly connected to the top of the pressure spring 33, and several snap-fit ​​blocks 35 are fixedly connected to the inner side of the connecting plate 31.

[0033] Specifically, such as Figure 3 As shown, the connecting rod 36 is slidably connected to the surface of the support rod 32, the surface of the connecting rod 36 is slidably connected to the connecting hole 25, and several snap-fit ​​blocks 35 are snapped into the inside of the snap-fit ​​hole 26.

[0034] In this embodiment: By setting the connecting plate 31 as the main support component of the limiting mechanism 3, a stable installation platform is provided for the entire heat sink fin assembly. The two support rods 32 on its rear side provide strong support for the connecting plate 31, ensuring that the heat sink fin assembly will not be deformed or damaged during use. The close cooperation with the moving module 23 and the heat sink fin body 1 improves the overall stability and reliability of the heat sink fin assembly. The support rods 32 are fixedly connected to both sides of the rear side of the connecting plate 31, providing support and guidance for the sliding of the connecting rod 36. The pressure spring 33 is sleeved on the surface of the support rod 32, playing a buffering and resetting role during assembly. When the moving module 23 moves downward, the pressure spring 33 is compressed due to the engagement between the moving module 23 and the locking block 35, absorbing part of the impact force and preventing damage to the heat sink fin body 1 and the limiting mechanism 3. When disassembly is required, the user separates the moving module 23 from the locking block 35. The pressure spring 33 supports the connecting rod 36 through the baffle 34, allowing the moving module 23 to move upward easily and enabling quick disassembly of the heat sink assembly. The baffle 34 is fixedly connected to the top of the pressure spring 33, providing stable support and limiting for the pressure spring 33. During assembly, the baffle 34 compresses the pressure spring 33 as the connecting rod 36 moves downward, ensuring that the compression of the pressure spring 33 is uniform and stable. When disassembly is required, the baffle 34 supports the connecting rod 36 through the restoring force of the pressure spring 33, allowing the moving module 23 to move upward smoothly. The snap-fit ​​block 35 is fixedly connected to the inner side of the connecting plate 31 and snaps into the snap-fit ​​hole 26 at the bottom of the moving module 23, ensuring the stability and reliability of the heat sink assembly during use. The connecting rod 36 is slidably connected to the surface of the support rod 32 and is slidably connected to the connecting holes 25 on both sides of the moving module 23, providing support and guidance for the movement of the moving module 23.

[0035] Specifically, such as Figure 4 As shown, torsion springs 4 are fixedly connected to both sides of the front side of the connecting plate 31, and baffles 5 are fixedly connected to the front side of the torsion springs 4.

[0036] Specifically, such as Figure 5 As shown, a reinforcing ring 6 is fixedly connected to the bottom of the support rod 32, and the surface of the reinforcing ring 6 is coated with an anti-corrosion coating.

[0037] In this embodiment: a torsion spring 4 is fixedly connected to both sides of the front side of the connecting plate 31, making it convenient for the user to open or close the baffle 5. The baffle 5 provides a certain degree of protection after assembly, preventing the heat sink fin body 1 from accidentally falling off. The reinforcing ring 6 increases the strength and stability of the support rod 32, preventing bending or breakage during use. The anti-corrosion coating improves the corrosion resistance of the support rod 32 and extends its service life.

[0038] Specifically, such as Figure 3 As shown, a protective pad 7 is fitted on the surface of the snap-fit ​​block 35. The surface of the protective pad 7 is engraved with anti-slip texture, and the surface of the protective pad 7 is in contact with the inner side of the snap-fit ​​hole 26.

[0039] Specifically, such as Figure 3 As shown, a protective sleeve 8 is fitted on the surface of the limiting block 24. The surface of the protective sleeve 8 is engraved with anti-slip texture, and the surface of the protective sleeve 8 is in contact with the inner side of the limiting module 21.

[0040] In this embodiment: by setting a protective pad 7 and covering the surface of the snap-fit ​​block 35, wear on the snap-fit ​​block 35 during frequent contact and snap-fit ​​with the snap-fit ​​hole 26 can be effectively prevented, extending the service life of the snap-fit ​​block 35. By setting an anti-slip texture, the friction between the two can be increased when in contact with the inner side of the snap-fit ​​hole 26, making the snap-fit ​​more secure and stable, preventing the heat sink fin assembly from loosening or accidentally separating during use. By setting a protective sleeve 8 and covering the surface of the limiting block 24, damage to the limiting block 24 during contact and snap-fit ​​with the limiting module 21 can be avoided, protecting the structural integrity of the limiting block 24 and ensuring its long-term stable limiting function. By setting an anti-slip texture, the friction coefficient between the two is increased when in contact with the inner side of the limiting module 21, allowing the limiting module 21 to be more securely snapped onto the limiting block 24, improving the connection stability of the entire module mechanism 2.

[0041] Working Principle: First, when assembling the heat sink fin assembly, the operator can engage the bottom of the heat sink fin body 1 with the fixing hole 22. The fixing hole 22 is connected to the top of the limiting module 21, providing a stable connection position for the heat sink fin body 1. Then, the limiting module 21 engages with the limiting block 24 inside the moving module 23. The combination of multiple limiting modules 21 can flexibly adjust the layout and spacing of the heat sink fins according to actual needs, thereby improving the heat dissipation effect. Afterward, the connecting holes 25 on both sides of the moving module 23 are slidably connected to the connecting rod 36 of the limiting mechanism 3, allowing the moving module 23 to move on the limiting mechanism 3. At the same time, the connecting holes 25 guide the movement of the moving module 23, ensuring that the moving module 23 can always maintain linear movement during assembly and adjustment, avoiding deviation or jamming. Then, the user slides the moving module 23 to the top of the locking block 35 inside the connecting plate 31, and the user slides the bottom of the moving module 23... The snap-fit ​​hole 26 engages with the snap-fit ​​block 35. During assembly, when the moving module 23 moves downward and engages with the snap-fit ​​block 35, it applies pressure to the pressure spring 33. The pressure spring 33 is sleeved on the surface of the support rod 32, and the baffle 34 is securely connected to the top of the pressure spring 33. The baffle 34 compresses the pressure spring 33 as the connecting rod 36 moves downward, ensuring that the compression of the pressure spring 33 is uniform and stable. During this process, the pressure spring 33 absorbs some of the impact force, effectively preventing damage to the heat sink body 1 and the limiting mechanism 3. When it is necessary to disassemble the heat sink assembly, the user moves the moving module 23 upward to separate the moving module 23 from the snap-fit ​​block 35. At this time, the baffle 34 supports the connecting rod 36 with the restoring force of the pressure spring 33, allowing the moving module 23 to move upward easily, thereby realizing the quick disassembly of the heat sink assembly. Finally, after the heat sink assembly is completed, the user closes the baffle 5 and the connecting plate 31.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
