Description

Technical Field

[0001] This utility model mainly relates to the field of computer heat sink technology, specifically to a detachable dustproof mesh structure for a computer heat sink. Background Technology

[0002] In the field of computer heat sinks, dust filters are used to intercept dust and ensure the cleanliness and stable operation of the heat dissipation system. Traditional dust filters are mostly fixed or have simple clips for connection. They require tools to install, making the operation cumbersome. After long-term use, dust filters accumulate dust and need to be cleaned or replaced. The disassembly and reassembly process is complicated, time-consuming, and not user-friendly for ordinary users. Furthermore, repeated disassembly and reassembly can easily damage heat sink components and affect the overall lifespan of the equipment.

[0020] See attached document Figure 1-6 A detachable dustproof mesh structure for a computer heat sink includes a positioning frame 1 and a dustproof mesh 2 installed in the positioning frame 1. The dustproof mesh 2 has a mesh pressing bracket 3 on one side and multiple magnetic pressing plates 4 on one side. The positioning frame 1 also has push-pull insert plates 5 embedded at both ends. The front end of the positioning frame 1 has a receiving cavity 101. The upper and lower ends of the receiving cavity 101 are provided with an upper baffle 102 and a lower baffle 103. The rear end of the positioning frame 1 is also provided with a mounting plate 104.

[0021] The receiving cavity 101 provides installation space for the dustproof net 2. The upper baffle 102 and lower baffle 103 extending from the upper and lower ends form a lateral limit to ensure that the edge of the dustproof net fits tightly with the frame and the inner wall corresponds. The magnetic strip 105 is embedded in the position of the magnetic pressure plate 4 to provide stable adsorption force. The receiving cavity 101 extends upward through the replacement groove 106 formed by the upper baffle 102. The width matches the thickness of the dustproof net 2 and serves as the access channel for taking out and putting in the dustproof net 2.

[0022] The mounting plate 104 is located at the rear end of the receiving cavity 101 and is connected to the mounting slot of the heat sink body through a snap-fit ​​structure. It can be fixed by applying a lateral force during installation. In another embodiment, it can also be fixed by screws through the screw holes reserved on the mounting plate 104.

[0023] The upper stop bar 102 and the lower stop bar 103 have a total of four countersunk holes 107 at both ends. The depth of the holes is greater than the length of the rotating positioning post 404 of the magnetic pressure plate 4. The step inside the countersunk hole matches the limiting platform 405 on the rotating positioning post 404 to prevent the rotating positioning post 404 from coming out of the hole.

[0024] The push-pull guide groove 107 is opened on the inner side of the upper stop bar 102 and the lower stop bar 103. The cross section is in the shape of a "T" and forms a sliding fit with the flange of the push-pull insert plate 5 to ensure that the insert plate does not shift during the push-pull process, while limiting its vertical displacement.

[0025] The dustproof net 2 is installed in the receiving cavity 101 of the positioning frame 1. One side is fixed by pressure through the net support 3 to keep it flat and avoid vibration and noise caused by wind. Its size is slightly smaller than the inner cavity size of the receiving cavity 101 to ensure that it can be flexibly pulled out after the magnetic pressure plate 4 is released.

[0026] The pressure mesh bracket 3 has a grid-like rib structure to ensure sufficient support strength. The edge of the pressure mesh bracket 3 corresponds to the reserved hole of the dustproof mesh 2 and the magnetic metal pin 403 of the magnetic suction plate 4, so as to evenly press the dustproof mesh 2 into the receiving cavity 101 and prevent it from shifting when the heat sink is working.

[0027] Multiple magnetic pressure plates 4 include a pressure plate 401, a sleeve 402, a magnetic metal pin 403, and a rotating positioning post 404. The magnetic metal pin 403 is embedded in the sleeve 402 to form a composite structure. After the magnetic metal pin 403 passes through the mounting hole of the pressure mesh bracket 3, it generates a magnetic attraction with the magnetic plate 105 in the positioning frame 1 to fix the pressure mesh bracket 3. The limiting platform 405 at the end of the rotating positioning post 404 is embedded in the stepped surface of the countersunk hole 107.

[0028] The push-pull insert plate 5 adopts a wedge-shaped block structure design, with an integrated anti-slip handle on the outside and an inner inclined surface angle that forms a contact fit with the bottom of the pressure plate 401 of the magnetic pressure plate 4. The upper and lower ends of the push-pull insert plate 5 are provided with flanges that match the push-pull guide groove 108 to ensure smooth sliding. When the push-pull insert plate 5 is pushed inward, the inclined surface characteristics of the wedge block will gradually lift the pressure plate 401 of the magnetic pressure plate 4. Through the lever principle, the magnetic metal pin 403 will move upward, so that it completely disengages from the magnetic sheet 105 and releases the magnetic attraction force. After the magnetic pressure plate 4 is lifted, a certain gap is formed between its bottom and the positioning frame 1. This gap, together with the replacement groove 106 of the upper baffle 102, becomes the removal channel of the dustproof net 2, so that the dustproof net 2 can be pulled out vertically upward, realizing tool-free quick disassembly.

[0029] In summary, when cleaning the dust filter 2, simply push the push-pull plate 5 inward to simultaneously release the four magnetic clamping plates. Then, pull the dust filter 2 directly out of the replacement slot 106. The entire process requires no tools. In the installed state, the magnetic clamping plates 4 are tightly attracted by magnetic force, and with the reverse support of the push-pull plate 5, the dust filter can be kept stable without loosening or abnormal noise when the radiator is operating at high wind speed. The dust filter 2 adopts a completely detachable structure, and can be directly washed or blown after removal, avoiding the problem of incomplete cleaning caused by the traditional fixed dust filter structure, effectively extending the service life of the radiator.

[0030] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
