Description

Technical Field

[0001] This application relates to the field of computer heat dissipation technology, and more particularly to fan modules and servers for servers. Background Technology

[0002] With the development of internet technology, the requirements for server architecture and power consumption performance are becoming increasingly stringent. To address the diverse and customized needs of server development, various types of air ducts are typically used to adjust airflow direction and volume. These air ducts are numerous and complex in design, requiring specific designs for each configuration and system architecture. This not only increases development costs but also extends product iteration cycles. Furthermore, the diversity of materials used in air ducts increases supply chain complexity and cost. In practical applications, their space requirements limit the implementation of high-density internal server structures, especially when server power consumption demands increase and architecture changes frequently. In these cases, existing air duct technologies struggle to meet flexible airflow adjustment needs.

[0003] In related technologies, the placement and airflow direction of fans in servers are usually preset. Once the server's configuration or architecture changes, such as adding or removing modules like CPU, memory, network cards, or hard drives, the original cooling configuration may not be able to effectively meet the new cooling demands. In this case, it is necessary to redesign the fan configuration or add additional cooling components, which not only increases the complexity of the server design but also limits the server's cooling efficiency and flexibility.

[0004] Furthermore, with the continuous development of server technology, the requirements for heat dissipation systems are also constantly increasing. Especially in the design of high-density servers, how to achieve effective airflow and airflow direction adjustment within a limited space to meet the heat dissipation needs of modules at different heights or positions has become a key challenge in the current server heat dissipation design. Summary of the Invention

[0006] This application provides a fan module for a server, including a first bracket, a fan body, a second bracket, and adjustable fan blades. The first bracket has a receiving groove with its opening facing the side of the first bracket. The fan body is located within the receiving groove. The second bracket is fastened to the opening of the receiving groove and has an air outlet. The adjustable fan blades are rotatably mounted on the second bracket and located at the air outlet. The second bracket has multiple sets of adjustment parts, spaced circumferentially around the second bracket. The adjustable fan blades have multiple sets of drive parts for correspondingly engaging with each of the adjustment parts. Only one set of drive parts is allowed to engage with the corresponding set of adjustment parts simultaneously, so that the engagement of one set of drive parts with the corresponding set of adjustment parts achieves adjustment of the air outlet's airflow direction.

[0007] In an exemplary embodiment, the first bracket has a fan terminal for mating with a server board; the fan module includes a first cable, a second cable, a temperature sensor, and a control module, wherein a first end of the first cable is electrically connected to the fan body, and a second end of the first cable is electrically connected to the fan terminal; a first end of the second cable is electrically connected to the drive unit, and a second end of the second cable is electrically connected to the fan terminal; the temperature sensor is integrated in the area where different heat-generating modules are located within the server to monitor the temperature in the area where different heat-generating modules are located in real time and acquire temperature information; the control module is integrated on the board, and the control module is signal-connected to the temperature sensor, so that the control module independently controls the operating mode of the fan body according to the temperature information to adjust the airflow of the fan module, and / or, so that the control module independently controls the rotation angle of the drive unit according to the temperature information to adjust the airflow direction of the fan module.

[0008] In an exemplary embodiment, the adjustment unit includes an open toothed groove formed on the second bracket, and the drive unit includes a gear motor disposed on the adjustment fan blade. The rotation angle of the adjustment fan blade is adjusted by the meshing of the external teeth of the gear motor with the internal teeth of the open toothed groove.

[0009] In an exemplary embodiment, the cross-section of the air outlet is circular; the adjusting fan blade is in the shape of a disc adapted to the air outlet, and multiple ventilation holes are opened on the disc-shaped adjusting fan blade, and the multiple ventilation holes are evenly distributed; a set of adjusting parts includes two symmetrically arranged open toothed grooves, and the line connecting the two open toothed grooves passes through the geometric center of the air outlet; a set of driving parts includes two symmetrically arranged gear motors, and the line connecting the two gear motors passes through the geometric center of the adjusting fan blade.

[0010] In one exemplary embodiment, the rotation angle of the fan blades is adjusted to a range of 0 to 35°.

[0011] In one exemplary embodiment, the first bracket and the second bracket are detachably connected.

[0012] In one exemplary embodiment, the receiving groove has a first latch on both sides of its opening, and the second bracket has a first buckle at a position opposite to the first latch, the first buckle engaging with the first latch; and / or, the receiving groove has a second buckle on both sides of its opening, and the second bracket has a second latch at a position opposite to the second buckle, the second buckle engaging with the second latch; and / or, the receiving groove has a third buckle at its top edge, and the second bracket has a third latch at a position opposite to the third buckle, the third buckle engaging with the third latch.

[0013] In one exemplary embodiment, the fan body has two sets of mounting holes. The first set of mounting holes faces the first bracket, and the second set of mounting holes faces the second bracket. The first set of mounting holes includes a plurality of first mounting holes, which are spaced apart around the circumference of the fan body. A first positioning post protrudes from the groove wall opposite to the first mounting hole and passes through the first mounting hole. The second set of mounting holes includes a plurality of second mounting holes, which are spaced apart around the circumference of the fan body. A second positioning post protrudes from the second bracket at a position opposite to the second mounting hole and passes through the second mounting hole.

[0014] In one exemplary embodiment, the outer peripheral cover of the first positioning post is provided with a first shock-absorbing rubber pad; and / or, the outer peripheral cover of the second positioning post is provided with a second shock-absorbing rubber pad.

[0015] This application also provides a server including multiple fan modules, which are arranged sequentially in a direction perpendicular to the direction from the front window to the rear window of the server, and the fan modules are the aforementioned fan modules.

[0016] This application presents a technical solution that, by configuring the fan module into a structure comprising a first bracket, a fan body, a second bracket, and adjustable fan blades, achieves flexible adjustment of the airflow direction at the outlet through the coordination of the adjustable fan blades and the second bracket. Specifically, multiple sets of adjustment components on the second bracket correspond one-to-one with multiple sets of drive components on the adjustable fan blades. This means that appropriate drive components and adjustment components can be selected and combined according to actual heat dissipation needs, thereby precisely controlling the airflow direction at the outlet. This dynamic airflow control capability significantly improves the efficiency and flexibility of internal server heat dissipation management, effectively responding to temperature changes in different areas, avoiding localized overheating, and extending the lifespan of server hardware. Furthermore, by allowing only one set of drive components to coordinate with one set of adjustment components, the accuracy and stability of each airflow adjustment are ensured, further optimizing the internal thermal environment of the server. Therefore, the technical solution of this application not only solves the problem that existing server fan modules are difficult to adapt to the heat dissipation needs of different areas, but also simplifies the structure of airflow direction and volume adjustment, reduces manufacturing costs and maintenance difficulty, and improves the overall operational stability and performance of the server.

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0036] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Embodiments of this application provide a fan module for a server and a server. The device is described in detail in conjunction with the structure and working principle of the fan module for a server and the server (the technical terms involved must be explained).

[0038] like Figures 1 to 7As shown, the fan module for a server includes a first bracket 10, a fan body 20, a second bracket 30, and an adjustable fan blade 40. The first bracket 10 has a receiving groove 11, with the opening of the groove facing the side of the first bracket 10. The fan body 20 is located within the receiving groove 11. The second bracket 30 is fastened to the opening of the receiving groove 11 and has an air outlet 31. The adjustable fan blade 40 is rotatably mounted on the second bracket 30 and located at the air outlet 31. The second bracket 30 has multiple sets of adjustment parts, spaced circumferentially around the second bracket 30. The adjustable fan blade 40 has multiple sets of drive parts for correspondingly engaging with each of the adjustment parts. Only one set of drive parts is allowed to engage with the corresponding set of adjustment parts at a time, so that the engagement of one set of drive parts with the corresponding set of adjustment parts achieves adjustment of the airflow direction of the air outlet 31.

[0039] By applying the technical solution of this application, the fan module is configured with a structure including a first bracket 10, a fan body 20, a second bracket 30, and adjustable fan blades 40. The core of this technical solution lies in the flexible adjustment of the airflow direction of the air outlet 31 through the cooperation of the adjustable fan blades 40 and the second bracket 30. Specifically, the multiple sets of adjustment parts on the second bracket 30 and the multiple sets of drive parts on the adjustable fan blades 40 can form a one-to-one correspondence. This means that an appropriate drive part and adjustment part can be selected to combine according to actual heat dissipation needs, thereby precisely controlling the airflow direction of the air outlet. This dynamic airflow control capability significantly improves the efficiency and flexibility of internal server heat dissipation management, effectively responds to temperature changes in different areas, avoids local overheating, and extends the lifespan of server hardware. In addition, by allowing only one set of drive parts to cooperate with one set of adjustment parts, the accuracy and stability of each airflow adjustment are ensured, further optimizing the internal thermal environment of the server. Therefore, the technical solution of this application not only solves the problem that server fan modules in the prior art are difficult to adapt to the heat dissipation needs of different areas, but also simplifies the structure of airflow direction and air volume adjustment, reduces manufacturing costs and maintenance difficulty, and improves the overall operational stability and performance of the server.

[0040] It should be noted that, in this application, if Figure 1 As shown, an embodiment of the fan module with left and right air outlets is given, such as... Figure 5 As shown, an embodiment of the fan module with top and bottom air outlets is given.

[0041] It should be noted that in this application, the first bracket 10 has a fan terminal for plugging into and engaging with a server board. The fan module includes a first cable, a second cable 50, a temperature sensor, and a control module. The first end of the first cable is electrically connected to the fan body 20, and the second end of the first cable is electrically connected to the fan terminal. The first end of the second cable 50 is electrically connected to the drive unit, and the second end of the second cable 50 is electrically connected to the fan terminal. The temperature sensor is integrated into the area where different heat-generating modules are located within the server to monitor the temperature in real time and acquire temperature information. The control module is integrated onto the board and is signal-connected to the temperature sensor. This allows the control module to independently control the operating mode of the fan body 20 based on the temperature information to adjust the airflow of the fan module, and / or to independently control the rotation angle of the drive unit based on the temperature information to adjust the airflow direction of the fan module. Thus, the fan terminal integrated on the first bracket 10 enables plugging into and engaging with the server board. The fan module further includes a first cable and a second cable 50. The first cable has a first end electrically connected to the fan body 20 and a second end electrically connected to the fan terminal, used to transmit the power and control signals required for fan operation. The second cable 50 has a first end electrically connected to the drive unit and a second end also electrically connected to the fan terminal, responsible for transmitting control signals to the drive unit to adjust the rotation of the fan blades. Temperature sensors are integrated into the areas where different heat-generating modules are located within the server, monitoring and acquiring temperature information in real time to provide data support for the control module. The control module is integrated on a board and connected to the temperature sensor signal. It can independently control the operating mode of the fan body 20 based on temperature information, adjusting the airflow of the fan module to adapt to the heat dissipation needs of different areas. Simultaneously, the control module can also independently control the rotation angle of the drive unit based on temperature information, adjusting the airflow direction of the fan module to ensure that airflow is accurately delivered to the modules requiring heat dissipation. This design achieves precise adjustment of airflow and direction in different areas within the server through software control, improving system heat dissipation efficiency while reducing development costs and material diversity caused by hardware complexity.

[0042] It should be noted that the control module mentioned above is a BMC (Baseboard Management Controller) system.

[0043] like Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the adjustment unit includes an open toothed groove 32 on the second bracket 30, and the drive unit includes a gear motor 41 mounted on the adjustment fan blade 40. The rotation angle of the adjustment fan blade 40 is adjusted by the meshing of the external teeth 411 of the gear motor 41 with the internal teeth 321 of the open toothed groove 32. In this way, the adjustment fan blade 40 achieves precise control of its rotation angle through the engagement of its gear motor 41 with the open toothed groove 32 on the second bracket 30. Specifically, the meshing of the external teeth of the gear motor 41 with the internal teeth of the open toothed groove 32 ensures the stability and accuracy of the adjustment fan blade 40 during rotation, allowing for dynamic adjustment of airflow and direction based on the temperature requirements of different areas within the server. Through real-time temperature monitoring by the BMC system and command output to the gear motor 41, the adjustment fan blade 40 can responsively change its angle, thereby optimizing airflow distribution and precisely meeting the heat dissipation requirements of each module. This structural design not only simplifies the complexity of the fan module but also improves the system's heat dissipation efficiency and resource utilization, while reducing development costs and material diversity. In other embodiments, the engagement between the gear motor 41 of the adjusting fan blade 40 and the open toothed groove 32 of the second bracket 30 can be varied to adapt to different server architectures and power consumption requirements, achieving efficient heat dissipation in a wider range of application scenarios. Furthermore, the design of the adjusting fan blade 40 can be further optimized, for example, by increasing the distribution density of the airflow holes or adjusting their thickness to improve airflow uniformity and heat dissipation effect. In this way, the system can more flexibly respond to changes in the internal temperature of the server, ensuring stable server operation.

[0044] like Figure 1 and Figure 5As shown, the cross-section of the air outlet 31 is circular; the regulating fan blade 40 is a disc shape adapted to the air outlet 31, and multiple ventilation holes 42 are evenly distributed on the disc-shaped regulating fan blade 40; a set of regulating parts includes two symmetrically arranged open toothed grooves 32, and the line connecting the two open toothed grooves 32 passes through the geometric center of the air outlet 31; a set of driving parts includes two symmetrically arranged gear motors 41, and the line connecting the two gear motors 41 passes through the geometric center of the regulating fan blade 40. Thus, the circular cross-section of the air outlet 31 facilitates uniform air distribution and flow. The disc-shaped design of the regulating fan blade 40, matching the air outlet 31, and the evenly distributed ventilation holes 42 on it effectively control the airflow distribution. To achieve precise control of the regulating fan blade 40, a set of regulating parts includes two symmetrically arranged open toothed grooves 32, and the line connecting these two open toothed grooves 32 passes through the geometric center of the air outlet 31, ensuring the balance of the regulating fan blade during rotation and precise control of the airflow direction. Correspondingly, a drive unit includes two symmetrically arranged gear motors 41, and the connection between these two gear motors 41 passes through the geometric center of the adjustable fan blade 40. This design ensures a uniform distribution of driving force, enabling the adjustable fan blade to respond stably and efficiently to the control commands of the BMC, whether adjusting the airflow up and down or left and right, thus adjusting the airflow requirements of modules at different heights or positions within the server. The cooperation between the gear motors 41 and the open toothed slots 32 constitutes the core mechanism for automatic fan airflow adjustment. By monitoring temperature changes in various areas within the system through the BMC, the fan direction and airflow are automatically adjusted, thereby optimizing the server's heat dissipation efficiency, reducing energy consumption, and extending the server's lifespan. In other embodiments not shown, the shape and driving method of the adjustable fan blade 40 can also be adjusted according to actual heat dissipation needs to adapt to more diverse server architectures and cooling scenarios.

[0045] It should be noted that in this application, the rotation angle of the adjustable fan blade 40 ranges from 0 to 35°. This ensures precise adjustment of the fan airflow. The BMC system automatically controls the angle of the adjustable fan blade 40 based on temperature changes in different areas within the server, thereby adjusting the direction and magnitude of airflow to meet specific cooling needs. Within this angle range, the adjustable fan blade 40 can effectively manage airflow in the vertical or horizontal directions, ensuring that the temperatures of critical server components such as the CPU, memory, network card, and hard drive storage areas remain within safe ranges. The rotation of the adjustable fan blade 40 is driven by small gear motors on its four central axes. These motors are connected to the BMC system on the server motherboard via cables, enabling precise angle adjustment according to commands. By limiting the rotation angle of the adjustable fan blade 40, not only is excessive adjustment leading to wasted airflow and increased noise avoided, but the fan system also ensures stable and efficient operation during server operation, providing continuous and precise cooling support for the server.

[0046] It should be noted that in this application, the first bracket 10 and the second bracket 30 are detachably connected. This detachable connection allows for flexible adjustment of the overall structure of the fan bracket to adapt to different server internal layout requirements without altering the fan's position. Specifically, this connection mechanism utilizes the interlocking of slots and hooks, ensuring secure installation of the fan assembly while providing convenient disassembly and assembly, greatly facilitating fan module management during server maintenance and upgrades. Furthermore, the precise linkage between the gear motor 41 and the open gear slot 32, which adjusts the fan blades 40, enables dynamic adjustment of airflow direction and volume, meeting the different heat dissipation needs of different areas of the server, effectively optimizing heat dissipation efficiency and reducing operating costs. In practical applications, the BMC monitoring system can monitor the server's internal temperature in real time and automatically control the angle of the fan blades 40, thereby precisely adjusting the airflow to the required area, ensuring the server operates within the optimal temperature range and avoiding performance degradation or other potential hardware failures caused by overheating. This approach not only simplifies the server's internal structure design and reduces the diversity of fan-related components but also improves the server's heat dissipation performance and overall reliability. In subsequent server iterations, the compatibility and adjustability of this fan bracket will greatly promote the reuse of structural designs, reduce development costs and time, and provide an innovative and practical solution for efficient server cooling.

[0047] like Figure 2 , Figure 3 , Figure 6As shown, the receiving groove 11 has a first latch 111 on both sides of the opening, and the second bracket 30 has a first buckle 33 at the position opposite to the first latch 111, and the first buckle 33 engages with the first latch 111; and / or, the receiving groove 11 has a second buckle 112 on both sides of the opening, and the second bracket 30 has a second latch 34 at the position opposite to the second buckle 112, and the second buckle 112 engages with the second latch 34; and / or, the receiving groove 11 has a third buckle 113 at the top edge of the opening, and the second bracket 30 has a third latch 35 at the position opposite to the third buckle 113, and the third buckle 113 engages with the third latch 35. In this way, the engagement of the first slot 111 with the first latch 33, and the engagement of the second latch 112 with the second slot 34, ensures a stable connection between the fan body and the bracket; the engagement of the third latch 113 with the third slot 35 further enhances the stability of the overall structure. These multi-point engagement designs not only simplify the assembly process and improve assembly efficiency, but also effectively reduce component loosening caused by vibration during server operation, ensuring the reliability and stability of the fan system. Through this multi-point engagement connection method, a robust assembly structure is formed between the fan bracket and the fan body, maintaining good working condition even in high-density server environments, ensuring efficient operation of the cooling system, and reducing the difficulty of maintaining and replacing fans. Of course, this engagement method can also be adapted to different server and fan specifications by adjusting the position and shape of the first, second, and third latches, providing wider applicability and flexibility for server fan zone airflow adjustment systems. In other embodiments not shown in the figure, a similar design principle can be adopted. By adjusting the number and layout of the clips and slots, a stable connection between the fan bracket and the fan body can be achieved, while meeting the needs of airflow regulation.

[0048] like Figure 2As shown, the fan body 20 has two sets of mounting holes. The first set of mounting holes faces the first bracket 10, and the second set of mounting holes faces the second bracket 30. The first set of mounting holes includes multiple first mounting holes 21, which are spaced apart circumferentially around the fan body 20. A first positioning post protrudes from the groove wall of the receiving groove 11 opposite to the first mounting hole 21 and passes through the first mounting hole 21. The second set of mounting holes includes multiple second mounting holes 22, which are spaced apart circumferentially around the fan body 20. A second positioning post protrudes from the second bracket 30 at a position opposite to the second mounting hole 22 and passes through the second mounting hole 22. Thus, the fan body 20 is designed with two sets of mounting holes, facing the first bracket 10 and the second bracket 30 respectively. The first set of mounting holes includes multiple first mounting holes 21, which are spaced apart circumferentially around the fan body 20. A first positioning post protrudes from the groove wall of the receiving slot 11 of the first bracket 10 opposite to the first mounting hole 21, passing through the first mounting hole 21 to achieve precise positioning and stable connection between the fan body and the first bracket. The second set of mounting holes consists of multiple second mounting holes 22, similarly spaced apart circumferentially around the fan body 20. A second positioning post protrudes from the second bracket 30 opposite to the second mounting hole 22, passing through the second mounting hole 22 to ensure stable assembly and precise alignment between the fan body and the second bracket. Through this design, the fan body is securely installed between the two brackets, improving the structural stability of the entire fan module and facilitating quick assembly and disassembly, simplifying maintenance and upgrades. Furthermore, this design allows for flexible installation of the fan body between different brackets, providing more diverse and efficient configuration options for the server's internal cooling system, helping to improve server cooling efficiency and space utilization. Especially when facing different airflow and direction requirements in different areas inside the server, it can ensure effective control of airflow direction and airflow by adjusting the fan blades through precise positioning and stable connection, thereby achieving efficient management of the internal temperature of the server.

[0049] like Figure 2As shown, the outer periphery of the first positioning post is provided with a first damping pad 114; and / or, the outer periphery of the second positioning post is provided with a second damping pad 36. Thus, the placement of the first damping pad 114 on the first positioning post and the second damping pad 36 on the second positioning post provides effective cushioning for the connection between the fan and the bracket, reducing vibration and noise during equipment operation. This design, by providing damping pads on the outer periphery of the positioning posts, not only enhances the stability of the fan structure but also optimizes the acoustic environment inside the server. The elastic properties of the damping pads can absorb the vibrations generated during fan operation, preventing these vibrations from being transmitted to the chassis structure or other electronic components, thereby ensuring the normal operating conditions of the internal components of the server and extending the service life of the equipment. Furthermore, the damping pads can also reduce resonance phenomena that may occur during fan rotation, further reducing noise levels and creating favorable conditions for quiet operation in the data center. Overall, the implementation of this technical solution ensures that the server can maintain good heat dissipation performance under high load, while maintaining stable operation and low noise characteristics, improving the overall performance of the server and the user experience. In server design, such attention to detail reflects a comprehensive consideration of reliability and user comfort, contributing to a more efficient and stable computing environment. Of course, besides the embodiment shown in the figure, the position and shape of the shock-absorbing pads can be adjusted according to actual application needs to adapt to different server architectures and environmental requirements. In other embodiments not shown, the layout and material selection of the shock-absorbing pads can be flexibly varied to achieve optimal shock absorption and device compatibility. Through the implementation of this technical solution, the operating efficiency of server fans has been significantly improved, while also enhancing the working environment of the data center.

[0050] It should be noted that this application provides a server comprising multiple fan modules 2, arranged sequentially along a direction perpendicular to the front to rear window of the server, and the fan modules 2 are those described above and below. By employing these fan modules 2, the server can manage its internal temperature more efficiently and flexibly, ensuring that critical components operate at suitable temperatures. Specifically, the cooperation of the first bracket 10, fan body 20, second bracket 30, and adjusting fan blades 40 of the fan module 2 provides dynamic airflow and air volume adjustment capabilities within the server. This not only helps the server cope with the heat dissipation needs of different areas but also automatically adjusts the fan's operating status according to real-time temperature changes, effectively reducing the risk of localized overheating within the server and improving hardware stability and lifespan. Furthermore, this design simplifies the structural complexity of the fan module 2, reduces the need for various air guide shrouds, thereby lowering the overall material cost of the server and making the server structure more compact and economical. Furthermore, the implementation of dynamic adjustment capabilities allows the server to more flexibly adjust its heat dissipation strategy in response to different application scenarios and workloads in the future, enhancing the overall adaptability and market competitiveness of the server. In summary, servers integrating this fan module 2 not only excel in thermal management but also offer advantages in structural optimization, cost control, and future compatibility, providing a solid foundation for stable server operation and performance improvement.

[0051] like Figure 8 As shown, after the server is assembled, it is divided into different areas according to the different needs of different components, power consumption and heat dissipation requirements. These include the server system 1, fan module 2, lower heat dissipation area 3, and upper heat dissipation area 4. The lower heat dissipation area 3 includes 32 memory modules and 2 CPUs, and the upper heat dissipation area 4 includes the network card and the rear hard disk storage area. Alternatively, depending on the system configuration, if the motherboard and the rear network card and hard disk are not fully configured, the system can be divided into left and right heat dissipation areas.

[0052] like Figure 9As shown, during server operation, the airflow and direction adjustment mechanism of fan module 2 automatically adjusts according to temperature changes in different areas inside the server. First, temperature sensors monitor the temperature of key heat-generating modules within the server in real time. After acquiring temperature information, the data is transmitted to the control module. Based on the received temperature information, the control module independently determines the operating mode of the fan body and the required rotation angle of the drive unit to adjust the airflow and direction. When the internal temperature of the server rises, especially when a certain area, such as the CPU or memory area, exceeds the preset temperature warning value, the control module outputs commands to the fan terminals through the BMC system, driving the first and second cables to control the fan body and gear motor respectively. The fan body adjusts its operating state according to the commands to increase or decrease airflow output, while the gear motor rotates according to the commands. The meshing of the gears with the open toothed slots adjusts the rotation of the fan blades, changing the airflow direction and precisely directing the airflow to the areas requiring heat dissipation. As the fan blades rotate, the airflow distributed through the multiple ventilation holes on them also changes, achieving adjustment of airflow density. When the server's internal temperature drops to a safe range, the control module, via the BMC system, adjusts the fan body and blades back to their default state or stops adjusting them, ensuring the server maintains an optimal operating temperature environment. This entire process is automated, efficiently responding to changes in the server's internal temperature, optimizing heat dissipation, and reducing development costs and material diversity caused by hardware complexity. It provides a flexible and economical solution for server thermal design.
