Description

[Technical Field]

[0001] This invention relates to the field of computer hardware technology, and specifically to a quick-release fastener for a heat sink. [Previous Technology]

[0002] In a computer hardware system, 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 may 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-cooled heatsinks equipped with high-performance fans, and further to water-cooled heatsinks with even higher cooling efficiency. In some extreme overclocking applications, 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 heat dissipation needs of chipsets. Power supply module heatsinks are also constantly evolving, ensuring a stable power supply to the CPU and other components while maintaining their own safe temperature range.

[0004] However, most heat sinks on the market are currently fixed to the motherboard with screws, making disassembly and assembly inconvenient. For example, Chinese mainland patent authorization announcement number CN205229944U uses multiple fastening screws to fix the support plate. Both installation and disassembly require the operation of multiple fastening screws, resulting in low efficiency. When the space in the motherboard case is compact, it is easily affected by interference from other hardware on the motherboard, making the disassembly and assembly of the heat sink even more inconvenient.

[0005] In view of the above, the inventors propose the following technical solution. [Summary of the Invention]

Implementation Method

[0018] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0019] As shown in Figures 1 to 5, a quick-release fastener for a radiator is provided, which includes a first locking device 2 and a second locking device 3 that cooperate to fix both ends of the radiator 1. The first locking device 2 includes a locking member 21 installed on the motherboard 4 and a fastening member 22 disposed at one end of the radiator 1 and capable of matching and fastening with the locking member 21. The connection between one end of the radiator 1 and the motherboard 4 is achieved by fastening the fastening member 22 onto the locking member 21. A first locking device 2, which fixes one end of the heat sink 1, is configured as a locking element 21 and a fastening element 22. The locking element 21 and the fastening element 22 are respectively fixed to the motherboard 4 and the heat sink 1. During heat sink 1 installation, the fastening element 22 is aligned with the locking element 21, and the other end of the heat sink 1 is swung to align with the motherboard 4. The second locking device 3 then fixes the heat sink 1 to the motherboard 4, thus replacing the traditional screw-based fixing method. This improves the installation efficiency of the heat sink 1 and allows for convenient installation in compact spaces, expanding its usability. Of course, the second locking device 3 can be a screw or a snap-fit ​​device, which will not affect the installation efficiency of the heat sink 1.

[0020] The fastening member 22 is installed at the bottom of the heat sink 1 by the first screw 23. The fastening member 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.

[0021] 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 element 21 is T-shaped, with the hook post 211 located at the upper end for the locking hooks 221 to hook simultaneously. The first screw 23 passes through the fastener 22 between the two locking hooks 221 and is connected and fixed to the radiator 1.

[0022] 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.

[0023] 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 disassembly. No additional connecting device is needed to fix the heat sink 1, making the structure simpler and the assembly and disassembly more convenient.

[0024] In summary, when using the present invention, firstly, the locking member 21 is fastened and installed on the motherboard 4, and the fastening 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 fastening 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 to the circuit board 4 by the second locking device 3.

[0025] The structure, features and effects of the present invention have been described in detail above with reference to the embodiments shown in the figures; however, the above description is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the figures. Therefore, any modifying changes that are consistent with the intent of the present invention should be included within the scope of the present invention patent as long as they are within the scope of equivalent effects.
