Description

Technical Field

[0001] This utility model relates to the field of computer hardware technology, and in particular to a graphics card fan that is easy to clean. Background Technology

[0002] In the field of computer hardware, the graphics card, as one of the core components, directly affects the efficiency of graphics processing and computing tasks. Graphics cards generate a significant amount of heat under high load, making thermal design a crucial part of their structure. Existing graphics cards typically employ a combination of heatsinks and fans for cooling. The heatsinks conduct heat away through contact with the main chip, while the fan accelerates heat dissipation through forced convection. However, over prolonged use, dust easily accumulates on the fans and heatsinks, leading to decreased cooling efficiency and potentially causing overheating, thus affecting the card's lifespan. In existing graphics card structures, components such as heatsinks, fans, and the casing are often fixed or difficult to disassemble. Cleaning dust often requires tools or professional assistance, making the process complex and time-consuming, hindering routine maintenance. Furthermore, the connection between the heatsinks and the printed circuit board in traditional graphics cards is often non-removable or semi-fixed, further increasing the difficulty of cleaning and maintenance. Therefore, designing a graphics card structure that is easy to disassemble and clean has become a pressing technical challenge. This invention aims to provide a graphics card fan that is easy to clean. By improving the connection method of the heat sink fins, fixing plate and top cover, it enables quick disassembly and efficient cleaning, thereby improving the heat dissipation performance and service life of the graphics card. Utility Model Content

[0003] The purpose of this invention is to provide a graphics card fan that is easy to clean, in order to overcome the shortcomings of the existing technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A graphics card fan designed for easy cleaning includes a printed circuit board, a top cover, heat sink fins, a mounting plate, and a fan. The heat sink fins are detachably connected to the printed circuit board via bolts. The bottom of the heat sink fins is tightly abutted against the main chip on the printed circuit board, and the top is fixedly connected to the mounting plate. Further, the mounting plate extends upward to form a pair of annular snap-fit ​​rings, each with multiple alignment grooves on its top for locking with the top cover. Specifically, the top cover is connected to the snap-fit ​​rings via a snap-fit ​​mechanism, thus forming an easily detachable structure.

[0006] Furthermore, the heat dissipation fins are designed with the following features: multiple ventilation gaps are formed on the surface of the heat dissipation fins, and these gaps are evenly distributed throughout the main body of the heat dissipation fins to increase the contact area between the heat dissipation fins and the air, thereby improving heat dissipation efficiency. The bottom of the heat dissipation fins directly abuts against the main chip on the printed circuit board, and the gaps are filled with thermally conductive material to ensure efficient heat conduction to the heat dissipation fins. In addition, the printed circuit board has multiple threaded holes for bolt connection with the heat dissipation fins, thus enabling the heat dissipation fins to be detachable.

[0007] Specifically, the mounting base is designed with multiple mounting through holes evenly distributed along its circumference. The mounting base is securely fixed to the heatsink fins by bolts passing through these holes, enabling its removability. Furthermore, a fan is rotatably connected to the mounting base; the fan's position is designed to directly act on the heatsink fins and printed circuit board, thereby enhancing the overall heat dissipation and ventilation of the graphics card.

[0008] Furthermore, the top cover is made of lightweight, high-strength material, and its inner side has multiple raised structures that correspond one-to-one with the alignment grooves on the fastening ring, thereby achieving a quick-locking connection between the top cover and the fastening ring. When it is necessary to clean the inside of the graphics card, the user only needs to apply appropriate external force to separate the top cover from the fastening ring, thereby exposing the internal structure of the graphics card.

[0009] In particular, the graphics card structure of this invention offers significant advantages in disassembly and cleaning. First, the snap-fit ​​connection between the top cover and the retaining ring makes the top cover easy to remove, facilitating the cleaning of dust adhering to the inside of the graphics card. Second, the heatsink fins are connected to the printed circuit board (PCB) by bolts; users can loosen the bolts to remove the heatsink fins from the PCB and clean the dust from the heatsink fins individually. Furthermore, the mounting plate is fixed to the heatsink fins by bolts; users can further remove the mounting plate to clean dust between the fan and the heatsink fins.

[0010] Furthermore, this utility model achieves modularity and easy disassembly of the graphics card structure through the above design. Specifically, S1: The user applies external force to separate the top cover from the fastening ring; S2: Loosen the bolts between the heat sink fins and the printed circuit board, and remove the heat sink fins; S3: Loosen the bolts between the fixing plate and the heat sink fins, and remove the fixing plate; S4: After cleaning the dust from the fan, heat sink fins, and printed circuit board, reassemble by reversing the disassembly sequence.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The modular design and detachable connection significantly improve the ease of cleaning the graphics card. In particular, the independent removal of the top cover, heatsink fins, and mounting plate allows users to thoroughly clean the dust inside the graphics card, effectively preventing dust accumulation from affecting performance and extending its lifespan. Simultaneously, the ventilation gaps on the heatsink fins and the synergistic effect of the fan and heatsink fins further enhance the graphics card's cooling performance, ensuring stable performance during extended operation.

[0022] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings:

[0023] An easy-to-clean graphics card fan, combined with... Figure 1 To be continued Figure 4 As shown, it includes a printed circuit board 5, a top cover 6, heat sink fins 4, a mounting plate 3, and a fan 8. These components, through modular design and detachable connection, achieve both easy cleaning and efficient heat dissipation for the graphics card. The specific embodiments of this utility model will be described in detail below with reference to the specific reference numerals in the accompanying drawings.

[0024] In this embodiment, the printed circuit board 5 is the core component of the entire graphics card, and it has multiple threaded holes 10 for detachable connection with other components. The heat sink fins 4 are located above the printed circuit board 5, with their bottoms directly abutting against the main chip on the printed circuit board 5. Thermally conductive material fills the gaps between them to ensure efficient heat transfer to the heat sink fins 4. The heat sink fins 4 are connected to the printed circuit board 5 by bolts, allowing them to be easily removed from the printed circuit board 5 for convenient cleaning of dust. The top of the heat sink fins 4 is fixedly connected to a fixing base 3, which extends upwards to form a pair of annular snap-fit ​​rings 2. Multiple alignment grooves 1 are provided on the top of the snap-fit ​​rings 2 for locking with the upper cover 6. The upper cover 6 is made of lightweight, high-strength material, and its inner side has multiple protruding structures that correspond one-to-one with the alignment grooves 1 on the snap-fit ​​rings 2, thus enabling a quick snap-fit ​​connection between the upper cover 6 and the snap-fit ​​rings 2. When it is necessary to clean the inside of the graphics card, the user only needs to apply appropriate external force to separate the top cover 6 from the fastening ring 2, thereby exposing the internal structure of the graphics card.

[0025] The heatsink fin 4 features a significantly innovative design, with multiple ventilation gaps 9 evenly distributed across its main body. This increases the contact area between the fins and air, thereby improving heat dissipation efficiency. The ventilation gaps 9 not only enhance heat dissipation but also facilitate cleaning. Users can easily remove dust from the surface and gaps of the heatsink fin 4 using a brush or air blower without disassembling the entire graphics card. Furthermore, the bottom of the heatsink fin 4 directly contacts the main chip on the printed circuit board 5, with thermally conductive material filling the gaps to ensure efficient heat transfer. The removability of the heatsink fin 4 further enhances cleaning convenience; users can simply loosen the screws to remove it from the printed circuit board 5 for deep cleaning.

[0026] The mounting base 3 incorporates multiple mounting holes 7 evenly distributed circumferentially around its surface. Bolts pass through these holes 7 to securely fasten the mounting base 3 to the heatsink fins 4, enabling its removability. A fan 8 is rotatably connected to the mounting base 3. The fan 8's position is designed to directly heat the heatsink fins 4 and the printed circuit board 5, thereby enhancing the overall cooling and ventilation of the graphics card. The fan 8 is flexibly adjustable via a rotating connection on the mounting base 3, allowing users to adjust its angle and position to optimize cooling performance. The removability of the mounting base 3 allows users to further remove it for cleaning dust between the fan 8 and the heatsink fins 4. This design not only improves the graphics card's cooling performance but also significantly enhances cleaning convenience.

[0027] In practice, users can complete the graphics card cleaning process by following these steps: S1: The user applies external force to separate the top cover 6 from the fastening ring 2, exposing the internal structure of the graphics card; S2: Loosen the bolts between the heatsink fins 4 and the printed circuit board 5, and remove the heatsink fins 4; S3: Loosen the bolts between the fixing plate 3 and the heatsink fins 4, and remove the fixing plate 3; S4: After cleaning the dust from the fan 8, heatsink fins 4, and printed circuit board 5, reassemble the graphics card by reversing the disassembly sequence. The above operation process is simple and easy to perform, and users can complete the comprehensive cleaning of the graphics card without professional tools.

[0028] This invention achieves modularity and easy disassembly of the graphics card structure through the above design, significantly improving the ease of cleaning the graphics card. Specifically, the snap-fit ​​connection between the top cover 6 and the fastening ring 2 makes the top cover 6 easy to disassemble, facilitating the user to clean the dust adhering to the inside of the graphics card. The heat sink fins 4 are connected to the printed circuit board 5 by bolts, and the user can loosen the bolts to remove the heat sink fins 4 from the printed circuit board 5, thereby cleaning the dust on the heat sink fins 4 separately. The fixing plate 3 is fixed to the heat sink fins 4 by bolts, and the user can further remove the fixing plate 3 to clean the dust between the fan 8 and the heat sink fins 4. This modular design allows each component of the graphics card to be disassembled and cleaned independently, effectively preventing the impact of dust accumulation on the graphics card performance, thereby extending the lifespan of the graphics card.

[0029] Furthermore, the ventilation gaps 9 on the heatsink fins 4 and the synergistic effect of the fan 8 and heatsink fins 4 further enhance the graphics card's cooling performance. The ventilation gaps 9 increase the contact area between the heatsink fins 4 and the air, thereby improving cooling efficiency. The fan 8, through a rotating connecting device, flexibly adjusts its position to ensure that airflow covers key areas of the heatsink fins 4 and the printed circuit board 5, thus enhancing the overall cooling and ventilation effect of the graphics card. This design not only improves the graphics card's cooling performance but also ensures stable performance during prolonged operation.

[0030] This invention's graphics card structure is particularly suitable for high-performance computing scenarios, such as gaming, video editing, and scientific computing. In these applications, graphics cards typically need to operate under high loads for extended periods, making heat dissipation performance and ease of cleaning especially important. This design allows users to easily disassemble the components for thorough cleaning after a period of operation, preventing dust accumulation that can lead to decreased heat dissipation and shortened lifespan. Simultaneously, the efficient heat dissipation design ensures stable performance even under high loads, meeting users' demands for high-performance computing.

[0031] In summary, this invention solves the technical shortcomings of traditional graphics cards, which are difficult to clean thoroughly due to their fixed internal structure, through modular design and detachable connection, significantly improving the ease of cleaning and heat dissipation performance. The venting gaps 9 on the heatsink fins 4 and the synergistic effect of the fan 8 with the heatsink fins 4 further enhance the heat dissipation effect of the graphics card, ensuring stable performance during long-term operation. Through the above design, this invention effectively extends the lifespan of the graphics card, providing users with a more convenient and efficient user experience.

[0032] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. For those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these 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.
