[0020] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0021] Please see Figure 1 The bracket assembly 100 includes a heat sink, a fan mounting bracket 30, and a fixing component 20. The heat sink 10, serving as the basic load-bearing structure of the bracket assembly 100, includes a heat sink body 11 and a wire clamping part 12. The heat sink body 11 provides structural support and a mounting base for the bracket assembly 100, while the wire clamping part 12, disposed on the heat sink body 11, is used for clamping and fixing the fan wires. The fan mounting bracket 30 is disposed on the heat sink body 11 and undertakes the functions of fan installation and fixing. The fan mounting bracket 30 can stably support various forces and vibrations generated during fan operation. By setting the fan mounting bracket 30, the stability and reliability of the entire bracket assembly 100 are ensured. The fixing component 20 is used to firmly fix the fan mounting bracket 30 to the heat sink body 11. By forming an integral structure with the heat sink body 11, the fixing component 20 ensures that the fan maintains a stable installation state under various operating conditions. The fan mounting bracket 30 is used to install the fan, providing a standardized installation interface and fixing point for the fan. The wire clamping part 12 is used to clamp the fan wires, and the wires are fixed and managed by clamping rather than by making holes.

[0022] Traditional fan brackets typically require holes in the heatsink profile for cable management. However, for high-end graphics cards, these holes directly impact the cooling performance and overall stability of the heatsink module. This embodiment eliminates the impact of holes on cooling performance by using a cable-clamping part 12 on the heatsink body 11 to secure the fan cables. The clamping method of the cable-clamping part 12 not only maintains the structural integrity of the heatsink body 11 but also provides a reliable fixation for the fan cables. The fan cables are securely fixed by the clamping action of the cable-clamping part 12, preventing loosening, swaying, or detachment during fan operation. The bracket assembly 100 forms a complete fan fixing structure, the heatsink 10 provides basic support, the fan mounting bracket 30 enables fan installation, the fixing component 20 ensures a secure connection, and the cable-clamping part 12 solves cable management, achieving reliable fixing and effective heat dissipation for multiple fans.

[0023] Please see Figure 2The fan mounting bracket 30 includes a fixing frame 31 and a wire embedding arm 32. The fixing frame 31 serves as the main structure of the fan mounting bracket 30, fixed to the heat sink frame 11, and is used for the main installation and support functions of the fan. The wire embedding arm 32 is fixed to the fixing frame 31 and is a wire management component of the fan mounting bracket 30. It is fixed to the fixing frame 31 and forms a functional extension of the fixing frame 31. The wire embedding arm 32 is used to embed the fan wires, providing a dedicated routing path and fixing position for the fan wires. Through the design of the wire embedding arm 32, the fan wires have a clear routing direction and fixing method starting from the fan connection point.

[0024] By setting up a fixing frame 31 and a wire embedding arm 32, the fixing frame 31 is used for mechanical fixation and structural support of the fan, ensuring that the fan maintains a stable installation position under various operating conditions. The wire embedding arm 32 is used for standardized management of the wires. By embedding the wires, the fan wires are organized and fixed according to a predetermined path. With the wire embedding arm 32, the fan wires are arranged in an orderly manner and reliably fixed, avoiding random distribution and tangling of the wires. The wire embedding arm 32 provides dedicated embedding space for each fan wire, ensuring that the wires will not shift due to vibration or other factors during fan operation.

[0025] In this embodiment, the overall performance of the fan mounting system is improved through the division of labor between the mounting bracket 31 and the wire embedding arm 32. The design of the mounting bracket 31 provides a more stable mounting foundation for the fan, effectively reducing vibration transmission and positional displacement during fan operation. The wire management function of the wire embedding arm 32 provides a standardized solution for wire organization in multi-fan systems, with each fan's wire having a clearly defined embedding location and routing path. The connection between the mounting bracket 31 and the heat sink 11 is optimized to ensure the connection's strength and reliability. The connection between the wire embedding arm 32 and the mounting bracket 31 also employs a reliable fixing method, ensuring that the wire embedding arm 32 will not loosen or fall off when bearing the weight of the wires and external stress. Through the embedding management of the wire embedding arm 32, the fan wires are transformed from a disordered distribution to an ordered arrangement. The embedding function of the wire embedding arm 32 not only solves the problem of wire fixing but also facilitates subsequent maintenance and repair. The standardized arrangement of the wires makes fault location and line inspection easier.

[0026] For further details, please refer to Figure 3The buried wire arm 32 includes an arm body 321, an extension member 322, a first wire pressing part 323, and a second wire pressing part 324. One end of the arm body 321 is fixed to a mounting frame 31, providing structural support and an installation base for the entire buried wire arm 32. The arm body 321, through its secure connection to the mounting frame 31, firmly integrates the buried wire arm 32 into the fan mounting bracket 30. The extension member 322 is fixed to the other end of the arm body 321. By providing the extension member 322, the buried wire arm 32 can be further extended in space, providing more operating space and installation positions for wire pressing and fixing. The extension member 322 and the arm body 321 form a continuous structure, ensuring the structural integrity of the entire buried wire arm 32. The first wire pressing part 323 and the second wire pressing part 324 are fixed to the extension member 322, constituting the core function of the buried wire arm 32. The first wire pressing part 323 and the second wire pressing part 324 are used to press the fan wires, firmly fixing the wires in a predetermined position through mechanical pressing. The design of the wire clamping section fully considers the physical characteristics and fixing requirements of the wire, ensuring that the clamping force can effectively fix the wire without damaging it.

[0027] More specifically, along the first direction, the first clamping portion 323 and the second clamping portion 324 are arranged in a staggered configuration. The first direction is defined as the thickness direction of the arm body 321, that is, the direction perpendicular to the main surface of the arm body 321. The staggered configuration means that the first clamping portion 323 and the second clamping portion 324 are at different heights along the thickness direction of the arm body 321, forming a staggered spatial layout. This staggered configuration provides a more flexible clamping path for the fan wire, improves the fixing effect, and effectively disperses stress concentration on the wire, preventing the wire from bearing excessive clamping force in a single position. The clamping function of the first clamping portion 323 and the second clamping portion 324 is achieved through precise structural design. The first clamping portion 323 and the second clamping portion 324 can provide sufficient clamping force and can adapt to different specifications of fan wires.

[0028] In this embodiment, the arm body 321, the extension member 322, the first wire clamping part 323, and the second wire clamping part 324 form a complete wire management chain. The fan wire starts from the arm body 321 at the end of the mounting bracket 31, is guided by the extension member 322, and is finally reliably fixed by the combined action of the first wire clamping part 323 and the second wire clamping part 324.

[0029] In this embodiment, multiple first pressure points 323 and second pressure points 324 form a multi-point pressure fixing array. Multiple first pressure points 323 are distributed on the extension member 322 at predetermined intervals, and multiple second pressure points 324 are similarly distributed on the extension member 322 at corresponding intervals. The arrangement of multiple pressure points provides multiple fixing points for the fan wire, enhancing the stability and reliability of the wire fixing. Multiple first pressure points 323 and second pressure points 324 are spaced apart along a second direction. The second direction is defined as the length direction of the arm body 321, that is, along the main extension axis of the arm body 321, forming an orderly distribution along the length of the arm body 321. The spacing is designed to consider the bending radius and fixing requirements of the wire, ensuring that each pressure point can effectively hold the wire. In the thickness direction of the arm body 321, adjacent first pressure points 323 and second pressure points 324 continue to maintain a staggered arrangement. In the length direction of the arm body 321, multiple first pressure points 323 are spaced apart, and multiple second pressure points 324 are also spaced apart. The layout patterns in both directions work together to form a multi-point pressure grid. Multiple first pressure points 323, distributed along the length of the arm 321, provide multiple pressure contact points for the fan wires. Under the combined action of the multiple first pressure points 323, the fan wires achieve a multi-segmented fixing effect, with each segment receiving independent pressure support. Multiple second pressure points 324 work in conjunction with the multiple first pressure points 323, providing pressure force at different locations on the wires, forming a distributed fixing network.

[0030] Please see Figure 3The first wire pressing part 323 includes a pressing part 301 and a limiting part 302. The pressing part 301 is fixed to the extension member 322, and the limiting part 302 is fixed to the surface of the pressing part 301 facing the second wire pressing part 324. The pressing part 301 and the limiting part 302 form a limiting groove 313, which is used to accommodate the fan wire. The pressing part 301, through its firm fixation with the extension member 322, stably integrates the first wire pressing part 323 into the buried wire arm 32 system, providing a reliable structural foundation for the installation of the limiting part 302 and the pressing of the wire. The setting of the limiting part 302 ensures that a suitable spatial relationship is formed between the limiting part 302 and the second wire pressing part 324. The limiting part 302, through its fixed connection with the pressing part 301, forms the complete structure of the first wire pressing part 323, providing lateral limiting and constraint functions for the fan wire. The limiting groove 313 is defined by the pressing part 301 and the limiting part 302, providing a dedicated receiving space for the fan wire. The limiting groove 313 can accommodate standard-sized fan wires and effectively constrains the wires spatially. The limiting groove 313 is used to receive the fan wire, providing a clear installation position and fixing space for the wire. The fan wire is placed inside the limiting groove 313 and is subject to multi-directional constraints from the groove 313 walls, resulting in a stable positioning effect. The receiving function of the limiting groove 313 not only solves the problem of fixing the wire's position but also provides protection for the wire, preventing accidental damage to the wire in the external environment.

[0031] In this embodiment, the fan wire is bidirectionally constrained by the pressure part 301 and the limiting part 302 within the limiting groove 313, forming a stable three-point or multi-point contact fixation. The internal contour of the limiting groove 313 matches the shape of the wire, ensuring the wire's fit and fixation effect within the groove 313. The opening design of the groove 313 facilitates the installation and adjustment of the wire while ensuring the stability of the wire after installation. The limiting grooves 313 of multiple first pressure parts 323 provide a standardized housing solution for multiple fan wires. Each limiting groove 313 has the same geometric parameters and housing capacity, realizing modularization and standardization of wire fixation. The distributed arrangement of the limiting grooves 313 allows multiple wires to be arranged in an orderly manner and reliably fixed according to a predetermined path. The cooperation between the limiting grooves 313 and the second pressure part 324 forms a complete wire fixing system. Under the housing effect of the limiting groove 313 and the pressing effect of the second pressure part 324, the fan wire achieves a multi-protected fixing effect, significantly improving the reliability and stability of wire management.

[0032] Please reconsider. Figure 3The mounting bracket 31 includes a chassis 311 and a mounting post 312. The mounting post 312 is fixed to the chassis 311, firmly integrating the mounting bracket 31 into the support assembly 100 and undertaking the load transfer function between the mounting bracket 31 and the heat sink 11. The mounting post 312, through its connection with the chassis 311, provides a direct mounting interface and support structure for the fan. The wire embedding arm 32 is fixed to the side wall of the chassis 311, realizing the integrated connection between the wire embedding arm 32 and the main structure of the mounting bracket 31. The side wall connection allows the wire embedding arm 32 to extend outward from the edge of the chassis 311, providing a guiding path for the fan wires from the center of the mounting bracket 31 to the periphery. The connection between the wire embedding arm 32 and the side wall of the chassis 311 ensures the rationality and aesthetics of the wire routing. The fixing post 312 is also provided with a groove 313 for mounting the fan. The groove 313 provides an accurate positioning reference and reliable mounting support for the fan, ensuring the positional accuracy and connection strength of the fan after installation. The mounting bracket 31 further includes a dustproof wall 314 structure to provide dust protection for the fan. The dustproof wall 314 is fixed to the chassis 311, forming an integrated protective structure with the chassis 311. Through its firm connection with the chassis 311, the dustproof wall 314 provides a surrounding dust barrier for the entire fan mounting area, effectively blocking the intrusion of external dust and impurities. The dustproof wall 314 is set around the fixing post 312, forming a ring-shaped protective structure centered on the fixing post 312. The surrounding design of the dustproof wall 314 ensures all-round dust protection coverage, preventing dust from penetrating into the fan area from all directions. The height and thickness parameters of the dustproof wall 314 are optimized according to the dustproof level requirements and space constraints. Furthermore, the dustproof wall 314 is provided with a notch 315, which is aligned with the buried wire arm 32. The notch 315 is used for the fan wire to extend out. The position of the notch 315 is aligned with the installation position of the buried wire arm 32, ensuring that the fan wire can smoothly enter the buried wire arm 32 from inside the dustproof wall 314 through the notch 315, forming a continuous wire path. In this embodiment, the dustproof wall 314 achieves the IP5X dustproof rating through its surround design and precise control of the notch 315. The dustproof wall 314 effectively blocks dust particles from entering the core area of ​​the fan, while the notch 315 design ensures necessary wiring channels, thus achieving a balance between dustproof protection and functional requirements.

[0033] In this embodiment, the chassis 311, the fixing column 312, the dustproof wall 314, and the buried wire arm 32 form a complete fan mounting and protection system. The chassis 311 provides basic support, the fixing column 312 realizes fan mounting, the dustproof wall 314 provides environmental protection, and the buried wire arm 32 is responsible for wire management. All components work together to form a fully functional mounting frame 31 structure.

[0034] For further information, please refer to [link / reference]. Figure 4 The fan mounting bracket 30 includes multiple mounting arms 33, forming a distributed fan mounting system. The multiple mounting arms 33 are fixed to a mounting frame 31. The multiple mounting arms 33 and the cable-embedded arms 32 are arranged around the mounting frame 31. The multiple mounting arms 33 serve as the main load-bearing components of the fan mounting bracket 30, and each mounting arm 33 has independent fan mounting capability and structural support function. The arrangement of multiple mounting arms 33 allows the bracket assembly 100 to support the installation of multiple fans simultaneously, meeting the application requirements of multi-fan cooling systems for large graphics cards. The fixing assembly 20 is used to fix the multiple mounting arms 33 to the heatsink body 11, achieving a stable structural integration through connection with the base 311 of the mounting frame 31. Each mounting arm 33 forms a reliable mechanical connection with the mounting frame 31, ensuring that the mounting arm 33 maintains a stable installation state when bearing the weight of the fan and operating load. Furthermore, the multiple mounting arms 33 and the cable-embedded arms 32 are arranged around the mounting frame 31 at predetermined angular intervals. The surrounding arrangement means that the mounting arms 33 and the cable-embedded arms 32 are arranged in a circular or polygonal pattern around the mounting bracket 31, with each component radiating outward from the center of the mounting bracket 31. This surrounding layout makes full use of the space around the mounting bracket 31, achieving a compact and orderly structural configuration. The fixing assembly 20 includes fixing units corresponding to the number of mounting arms 33, each unit responsible for connecting and fixing one mounting arm 33 to the heat sink 11. The fixing assembly 20 uses a multi-point fixing method to simultaneously lock all mounting arms 33 onto the heat sink 11, forming a unified installation effect. Multi-point fixing significantly enhances the installation stability and structural reliability of the multi-fan system.
