Description

Technical fields:

[0001] This utility model relates to the field of computer hardware technology, and specifically to a quick-release fastener for a heat sink. Background technology:

[0002] In computer hardware systems, the motherboard, as the core platform connecting various components, is crucial for heat dissipation. Various chips on the motherboard, such as the CPU, chipset, and power supply modules (MOSFETs), generate heat during computer operation. The CPU, in particular, as the computer's processing core, experiences increased power consumption with its ever-improving performance, resulting in more significant heat generation. If heat dissipation is ineffective, these components on the motherboard can overheat, leading to performance degradation, decreased stability, or even damage, severely impacting the overall performance and lifespan of the computer.

[0003] To address motherboard heat dissipation issues, heatsinks for different components have emerged. Early heatsinks were relatively simple, but they have become increasingly diverse and complex with technological advancements. Taking CPU heatsinks as an example, they have evolved from simple aluminum heatsinks to air coolers equipped with high-performance fans, and further to more efficient water coolers. In extreme overclocking scenarios, there are even special cooling methods such as liquid nitrogen cooling. Chipset heatsinks have also evolved from simple small heatsinks to more efficient and rationally designed modules to meet the ever-increasing cooling demands of chipsets. Power supply module heatsinks have also continuously evolved, ensuring a stable power supply to the CPU and other components while maintaining their own safe temperature range.

[0004] However, most heatsinks on the market currently use screws to secure them to the motherboard, making disassembly and assembly inconvenient. For example, Chinese patent publication number CN205229944U uses multiple screws to fix the support plate. Both installation and disassembly require operating on multiple screws, resulting in low efficiency. In cases with limited space, this can easily be affected by interference from other hardware on the motherboard, making heatsink disassembly and assembly even more inconvenient.

[0005] In view of the above, the inventors propose the following technical solution. Utility model content:

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a quick-release fastener for radiators.

The first locking device includes a locking component installed on the motherboard and a fastening component disposed at one end of the heat sink and capable of matching and fastening with the locking component. The connection between the fixed end of the heat sink and the motherboard is achieved by fastening the fastening component onto the locking component.

[0008] Furthermore, in the above technical solution, the fastener is installed on the bottom of the radiator by a first screw, and the fastener is provided with at least one locking hook for hooking the locking member.

[0009] Furthermore, in the above technical solution, the top of the fastener is provided with a positioning protrusion, and the bottom of the radiator is provided with a positioning groove that matches the positioning protrusion.

[0010] Furthermore, in the above technical solution, the lower end of the locking component is fixedly connected to the motherboard, and the upper end of the locking component is provided with a hook post for the locking hook to engage.

[0011] Furthermore, in the above technical solution, the fastener is provided with two locking hooks, the locking member is T-shaped, and the hook post is located at the upper end for the locking hooks to hook at the same time.

[0012] Furthermore, in the above technical solution, the first screw passes through the fastener between the two locking hooks and is fixed to the radiator.

[0013] Furthermore, in the above technical solution, the locking component is located next to the electrical connector on the motherboard, and there is a gap between the locking component and the electrical connector for the fastening component to be inserted and fastened to the locking component.

[0014] Furthermore, in the above technical solution, the second locking device is a second screw or a snap-fit ​​device.

[0015] Furthermore, in the above technical solution, the motherboard is provided with a nut seat for fixing with the second screw.

[0016] Furthermore, in the above technical solution, the other end of the heat sink is provided with a C-shaped groove corresponding to the second screw. The C-shaped groove corresponds to the fixing groove of the electronic component, and the electronic component is fixed to the motherboard by the second screw.

[0017] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: In the present invention, the first locking device for fixing one end of the heat sink is set as a locking member and a locking buckle, and the locking member and the locking buckle are respectively fixed to the motherboard and the heat sink.

[0023] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0024] See Figures 1 to 5As shown, a quick-release fastener for a heatsink includes a first locking device 2 and a second locking device 3 that engage to fix both ends of a heatsink 1. The first locking device 2 includes a locking member 21 mounted on a motherboard 4 and a fastening member 22 located at one end of the heatsink 1 and capable of engaging with the locking member 21. The connection between one end of the heatsink 1 and the motherboard 4 is achieved by fastening the fastening member 22 onto the locking member 21. By configuring the first locking device 2 for fixing one end of the heatsink 1 as a locking member 21 and a fastening member 22, and fixing the locking member 21 and the fastening member 22 to the motherboard 4 and the heatsink 1 respectively, during the installation of the heatsink 1, the fastening member 22 is engaged with the locking member 21, and then the other end of the heatsink 1 is swung to engage with the motherboard 4 and fixed to the motherboard 4 by the second locking device 3. This achieves the installation and fixation of the heatsink 1, replacing the traditional screw fixing method, thereby improving the installation efficiency of the heatsink 1 and allowing for convenient installation in compact and narrow spaces, thus expanding the application range of the heatsink 1. Of course, the second locking device 3 can be a screw or a snap-fit ​​device, and it will not affect the installation efficiency of the radiator 1.

[0025] The fastener 22 is installed at the bottom of the heat sink 1 by the first screw 23. The fastener 22 is provided with at least one locking hook portion 221 for hooking the locking member 21. The lower end of the locking member 21 is fixedly connected to the motherboard 4, and the upper end of the locking member 21 is provided with a hook post portion 211 for the locking hook portion 221 to fasten.

[0026] The top of the fastener 22 is provided with a positioning protrusion 222, and the bottom of the radiator 1 is provided with a positioning groove 11 that matches the positioning protrusion 222. The fastener 22 is provided with two locking hooks 221, and the locking member 21 is T-shaped, with a hook post 211 located at the upper end for the locking hooks 221 to simultaneously hook onto it. The first screw 23 passes through the fastener 22 between the two locking hooks 221 and is connected and fixed to the radiator 1.

[0027] The locking member 21 is located next to the electrical connector 5 on the motherboard 4, and there is a gap 40 between the locking member 21 and the electrical connector 5 for the fastener 22 to be inserted and fastened to the locking member 21. By leaving a gap 40 between the locking member 21 and the electrical connector 5, the fastener 22 can be flipped onto the locking member 21, and the height of the locking member 21 is lower than that of the electrical connector 5, so that after the heat sink 1 swings and attaches to the electronic component 6, the fastener 22 and the locking member 21 can remain tightly fastened, thereby locking and fixing the heat sink 1.

[0028] The second locking device 3 is a second screw or a snap-fit ​​device. The motherboard 4 is provided with a nut seat 41 for fixing with the second screw. The other end of the heat sink 1 is provided with a C-shaped groove 12 corresponding to the second screw. This C-shaped groove 12 corresponds to the fixing groove of the electronic component 6, and the electronic component 6 is fixed to the motherboard 4 by the second screw. In this embodiment, the electronic component 6 is a solid-state drive. By setting the second locking device 3 as a screw, it is convenient to simultaneously fix the heat sink 1 and the electronic component 6 to the motherboard 4 with the screw, achieving quick installation and removal. No additional connecting device is needed to fix the heat sink 1, making the structure simpler and the assembly and disassembly more convenient.

[0029] In summary, when using this utility model, firstly, the locking member 21 is fastened and installed onto the motherboard 4, and the locking member 22 is fixed to the bottom of the heat sink 1 by the first screw 23. After the electronic component 6 is inserted into the electrical connector 5, the locking member 22 at the bottom of the heat sink 1 is inserted from the gap 40 and fastened to the locking member 21. Then, the other end of the heat sink 1 is swung and pressed against the electronic component 6, so that the C-shaped groove 12 corresponds to the nut seat 41. The heat sink 1 and the electronic component 6 are locked and fixed onto the circuit board 4 by the second locking device 3.
