[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to a Chinese patent application filed with the Patent Office of China on January 16, 2024, with application number 202410060674.4, entitled “A Server and Its Aerodynamic Noise and Heat Dissipation Optimization Control System,” the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present application relates to a server and an aerodynamic noise and heat dissipation optimization control system thereof. Background Art

[0004] Servers are a crucial component of electronic devices, primarily used to provide computing services. Depending on the type of service they provide, they can be categorized as file servers, database servers, application servers, web servers, and more. The primary components of a server include a chassis, motherboard, CPU (Central Processing Unit), GPU (Graphic Processing Unit), hard drive, memory, power supply, and heat sink, similar to the architecture of a typical computer.

[0005] As the configuration and performance of electronic devices such as servers become increasingly powerful, the demand for heat dissipation performance is also increasing. Overheating of server components is one of the most common causes of product failure. In actual applications, the direct cause of failure of almost all electronic components is excessive package temperature.

[0006] Currently, conventional servers still primarily rely on forced-air cooling to dissipate heat from various server components. Only certain components that generate excessive heat require additional cooling methods, such as liquid cooling. In highly compact and integrated electronic devices, geometric size and increased convective heat transfer efficiency are key competitive advantages. Given a specific server architecture, fan performance is the most effective factor in increasing convective heat transfer efficiency.

[0007] In the prior art, in order to maximize fan performance, traditional servers often install a larger number of larger and more powerful cooling fans in the chassis to accelerate heat convection and perform heat exchange on server components, thereby reducing the temperature of server components. However, when using larger and more powerful cooling fans or increasing the number of cooling fans to improve heat dissipation efficiency, when the number of cooling fans increases to a certain level or the power increases to a certain level, the noise generated by the cooling fans during operation will be very large, and data centers usually have strict requirements on the operating noise of servers. On the contrary, in order to control the noise of the server within the required range, in the prior art, the power of a single cooling fan must be limited to a certain range to reduce the speed of the fan blades and thereby reduce the noise generated when the fan blades rotate. When the number of cooling fans is fixed, this will lead to a significant decrease in heat dissipation performance, which may result in the temperature of the server failing to drop to the expected target. In short, the heat dissipation control system in the prior art is difficult to achieve a balance between heat dissipation performance and noise.

[0008] Therefore, how to minimize the noise generated by the cooling fan while ensuring sufficient cooling performance and achieve a balance between cooling performance and noise is a technical problem faced by those skilled in the art. Summary of the Invention

[0032] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] Please refer to FIG1 , which is a schematic diagram of the overall structure of a specific implementation method provided by this application.

[0034] In a specific embodiment provided in the present application, the aerodynamic noise and heat dissipation optimization control system mainly includes a cooling fan 2, a temperature detection module 3, a noise detection module 4, a power consumption detection module 5, a controller 6 and a phase change air guide cover 7.

[0035] The cooling fans 2 are specifically disposed within the server chassis 1, typically at the front and rear ends of the chassis 1. Multiple fans may be provided. These fans are primarily used to create forced convection within the chassis 1, generating a cooling airflow that is blown into the chassis 1 to cool the server components installed therein. Furthermore, the aerodynamic area of ​​the cooling fans 2 can be adjusted to accommodate the varying cooling requirements of the server components.

[0036] Temperature detection module 3 is specifically disposed within the server chassis 1 and is primarily used to monitor the internal temperature of chassis 1 in real time. This internal temperature reflects the overall heating status of each server component during the current server operation. Under normal circumstances, the detection value of temperature detection module 3 will gradually fluctuate within a certain range based on the overall heating status of each server component. The overall heating status of each server component is primarily related to the real-time power of each server component. The greater the total power of each server component, the more severe the heating status, and vice versa.

[0037] The noise detection module 4 is set in the chassis 1 of the server, and is mainly used to detect the internal noise of the chassis 1 in real time. The internal noise is mainly generated by the operation of the cooling fan 2, that is, the aerodynamic noise generated by the friction between the fan blades 23 and the air. The faster the speed of the cooling fan 2 and the greater the power, the greater the aerodynamic noise, and vice versa.

[0038] The power consumption detection module 5 is primarily used to obtain the load requirements of the currently running program on the server and can also detect the real-time power consumption of each server component. When the server runs a specific program, the server system will activate the necessary server components and maintain them within certain operating parameters (related to power) based on the program's requirements. These required operating parameters are referred to as the load requirements. Furthermore, each server component enters its own operating state after powering on the server and has its own real-time power consumption.

[0039] As shown in FIG2 and FIG3 , FIG2 is a control principle topology diagram of the controller 6 , and FIG3 is a module structure diagram of the controller 6 .

[0040] The controller 6 maintains signal connection with the control end of the cooling fan 2, the temperature detection module 3, the noise detection module 4 and the power consumption detection module 5, and can receive the detection data sent by the temperature detection module 3, the noise detection module 4 and the power consumption detection module 5 in real time. It is mainly used to send corresponding control instructions to the control end of the cooling fan 2 according to the detection value of the temperature detection module 3, so as to adjust the working conditions of the cooling fan 2 (such as power and / or aerodynamic area, etc.), so that the power of the cooling fan 2 changes according to the detection value of the temperature detection module 3, thereby ensuring that the cooling fan 2 can produce sufficient heat dissipation performance.

[0041] The phase change air guide cover 7 is mainly used to guide the airflow generated by the cooling fan 2 so that the airflow can flow to each server component separately, and absorb the heat of the server components through the phase change material, thereby improving the heat dissipation efficiency of the server components.

[0042] Importantly, the controller 6 is also used to determine whether the detection value of the noise detection module 4 reaches a preset threshold. If so, it means that as the power of the cooling fan 2 increases, the noise generated when the cooling fan 2 is running has exceeded the data center requirements. At this time, the controller 6 analyzes the minimum operating power of each server component (that is, the minimum power that can support the server to maintain normal operation of the current program) according to the load demand obtained by the power consumption detection module 5, and adjusts the current power value of each server component to the corresponding minimum operating power accordingly, thereby saving the excess power of some necessary server components and / or saving the entire power of some currently non-essential server components, and then quickly reducing the overall power consumption of each server component, so that the total heat generation of each server component drops rapidly until it is lower than the heat dissipation of the cooling fan 2. The internal temperature of the chassis 1 will gradually drop, and the detection value of the temperature detection module 3 will also decrease synchronously, and finally the power of the cooling fan 2 is correspondingly lowered by the controller 6, and the noise generated by the cooling fan 2 and the internal noise of the chassis 1 are also weakened.

[0043] In this way, the aerodynamic noise and heat dissipation optimization control system provided in this embodiment, through the real-time detection of the internal temperature of the chassis 1 by the temperature detection module 3, the real-time detection of the internal noise of the chassis 1 by the noise detection module 4, the real-time power detection of each server component by the power consumption detection module 5, and the load requirements of the currently running program of the server obtained by the power consumption detection module 5, uses the controller 6 to adjust the working condition of the cooling fan 2 according to the detection value of the temperature detection module 3, to ensure that the heat dissipation of the cooling fan 2 can keep up with the heat dissipation requirements of each server component; at the same time, if the noise is too high due to the excessive working condition of the cooling fan 2, the controller 6 adjusts the current power of each server component to the corresponding minimum operating power according to the current load requirements of the server, so as to reduce the total heat generation of each server component by minimizing the power consumption of the entire server on the basis of ensuring the normal operation of the program, thereby rapidly reducing the internal temperature of the chassis 1, and then reducing the power of the cooling fan 2, and naturally weakening the noise.

[0044] In summary, the aerodynamic noise and heat dissipation optimization control system provided in this embodiment can minimize the noise generated by the cooling fan 2 while ensuring that the cooling fan 2 produces sufficient heat dissipation performance, thereby achieving a balance between heat dissipation performance and noise.

[0045] For example, when an AI (Artificial Intelligence) server is running an image analysis program, the system program mainly calls server components such as the central processing unit, graphics processing unit, memory card, and solid-state drive. However, the program actually only has a high computing power requirement for the graphics processing unit, and has a low requirement for other server components such as the central processing unit. Therefore, the real-time power of server components such as the central processing unit can be greatly reduced to the corresponding minimum operating power. At the same time, the graphics processing unit of the AI ​​server has strong performance and high computing power, so it usually does not need to run at full power. On the basis of ensuring the normal operation of the system program, the power can also be appropriately reduced to the current corresponding minimum operating power.

[0046] Of course, in an emergency, it is also possible to quickly reduce the total power consumption of each server component by temporarily sacrificing the performance of the server components, that is, reducing the power of the necessary server components to below the corresponding minimum operating power. However, this may cause the system programs to run slowly, so this operation can only be done for a short time.

[0047] In a specific embodiment of the power consumption detection module 5, to facilitate the power consumption detection module 5 to obtain the load requirements of the currently running program on the server and the real-time power consumption of each server component, in this embodiment, the power consumption detection module 5 specifically maintains a signal connection with the baseboard management controller 6 (BMC) on the motherboard. With this configuration, since the BMC 6 can monitor the operating status of each server component on the motherboard through various sensors on the motherboard, and the signals need to be transmitted through the motherboard when the system program is running, the power consumption detection module 5 can accurately and timely obtain the load requirements of the currently running program on the server from the BMC 6, and at the same time obtain the real-time power consumption of each server component.

[0048] Of course, the method for the power consumption detection module 5 to obtain the load requirements of the currently running program on the server and the real-time power of each server component is not limited to the above-mentioned baseboard management controller 6. For example, it can also be connected to the central processing unit signal to obtain the load requirements of the currently running program from the central processing unit, and simultaneously detect the real-time power of each server component through multiple power sensors.

[0049] In some embodiments, the power consumption detection module 5 may be a computer-readable instruction loaded on the controller 6 , and the controller 6 obtains the real-time power of each server component of the server and the load requirements of the currently running program of the server by executing the computer-readable instruction.

[0050] As shown in FIG4 , FIG4 is a schematic diagram of the specific structure of the heat dissipation fan 2 .

[0051] In a specific embodiment of the cooling fan 2, the cooling fan 2 is specifically installed on the front panel or rear panel of the chassis 1. Multiple cooling fans 2 can be installed simultaneously, and the multiple cooling fans 2 are evenly distributed along the width of the chassis 1. Specifically, the cooling fan 2 mainly includes a main drive motor 21, a mounting post 22, and fan blades 23. Generally, the cooling fan 2 is installed in the chassis 1 as a whole via a frame structure such as a mounting frame. The mounting frame is usually shared by multiple cooling fans 2 to achieve integrated installation of multiple cooling fans 2. The mounting frame is detachably connected to the chassis 1, allowing for convenient disassembly and maintenance.

[0052] Among them, the main drive motor 21 is arranged on the mounting frame, and can output rotational motion and torque, and the output shaft of the main drive motor 21 forms a power connection with the mounting column 22, such as being embedded in the mounting column 22, etc., and is mainly used to drive the mounting column 22 to rotate. The mounting column 22 is also located in the mounting frame, and is mainly used to install the fan blades 23, which can rotate under the power drive of the main drive motor 21. The fan blades 23 are arranged on the mounting column 22, generally specifically on the outer circular surface of the mounting column 22, and multiple blades are arranged at the same time, such as 3 to 12 blades; each fan blade 23 is evenly distributed circumferentially on the outer circular surface of the mounting column 22, and has a certain inclination angle, and two adjacent fan blades 23 are separated by a central angle of 30° to 120° to form an axial flow fan.

[0053] Accordingly, the controller 6 mainly includes a fan control module 61. The fan control module 61 forms a signal connection with the control end of the main drive motor 21 in the cooling fan 2, and is mainly used to send control instructions to the control end of the main drive motor 21 to control the working state of the main drive motor 21, such as parameters such as the motor rotation speed and the motor rotation direction. Specifically, the detection data of the temperature detection module 3 is mainly sent to the fan control module 61, and the fan control module 61 is mainly used to match the corresponding speed value according to the detection value of the temperature detection module 3 and the preset speed-flow-temperature correspondence, and send the matching result to the control end of the main drive motor 21, so that the main drive motor 21 adjusts the speed to the target speed, thereby ensuring that the current cooling performance of the cooling fan 2 is adapted to the total cooling requirements of each server component in the current server, thereby avoiding energy waste and high noise caused by excessive cooling performance, and also avoiding insufficient cooling performance causing the internal temperature of the chassis 1 to rise rapidly.

[0054] As shown in FIG. 5 , FIG. 5 is a schematic diagram of the installation structure of the fan blade 23 in the installation column 22 .

[0055] Furthermore, considering that when the detection value of the noise detection module 4 reaches a preset threshold, it indicates that the total heat dissipation demand of each server component in the current server is relatively high, if the rotation speed of the cooling fan 2 is further increased, the noise generated will be more obvious. In view of this, in order to improve the heat dissipation efficiency without additionally increasing the power of the cooling fan 2, in this embodiment, the fan blades 23 are not fixedly connected to the mounting column 22, but form a movable connection with the mounting column 22. Specifically, a sunken groove-type inner cavity is provided in the outer circular surface of the mounting column 22, and the inner cavity extends along the radial direction of the mounting column 22, and the root of the fan blade 23 is telescopically embedded in the inner cavity, and can slide radially in the inner cavity to achieve a telescopic effect. At the same time, when the detection value of the noise detection module 4 reaches the preset threshold, the fan control module 61 controls the fan blades 23 to extend radially outward. With this arrangement, when each fan blade 23 extends outward, a larger area of ​​the fan blade 23 is exposed outside the mounting post 22, thereby increasing the effective aerodynamic area of ​​the fan blade 23. This, in turn, increases the flow of cold air while maintaining a constant rotational speed of the mounting post 22 (and keeping the power of the cooling fan 2 essentially constant), ultimately improving the cooling efficiency of the server. Of course, if the total cooling demand or total power of the various server components within the server decreases, the fan control module 61 can be used to control each fan blade 23 to retract radially inward to its initial position, thereby appropriately reducing cooling performance.

[0056] It should be noted that the two methods of reducing the heat dissipation performance of the cooling fan 2, namely reducing the power and retracting the fan blades 23 radially inward, can be used separately or simultaneously; similarly, the two methods of increasing the power and extending the fan blades 23 radially outward to improve the heat dissipation performance of the cooling fan 2 can be used separately or simultaneously.

[0057] Furthermore, in order to facilitate the precise control of the radial extension and retraction movement of each fan blade 23 by the fan control module 61, this embodiment adds an auxiliary drive motor 24, a screw 25, and an adjustment slider 26 to the cooling fan 2. The auxiliary drive motor 24 is embedded in the inner cavity of the mounting column 22 and is specifically a micro motor. The control end of the auxiliary drive motor 24 forms a signal connection with the fan control module 61 and can change the working state, such as the rotation speed, rotation direction, and other parameters, by receiving control instructions sent by the fan control module 61. The screw 25 is also embedded in the inner cavity of the mounting column 22, and one end of the screw 25 forms a power connection with the output shaft of the auxiliary drive motor 24, while the other end of the screw 25 is rotatably inserted into the inner wall of the inner cavity and can perform synchronous rotation under the drive of the auxiliary drive motor 24. The adjusting slider 26 is also embedded in the inner cavity of the mounting post 22 and forms a sliding connection with the inner cavity. A threaded hole is provided on the adjusting slider 26 to form a threaded connection with the screw rod 25 through the threaded hole. At the same time, due to the inner cavity of the mounting post 22, when the screw rod 25 rotates, the adjusting slider 26 cannot rotate. The rotational force is converted into linear force through the threaded transmission, so that the adjusting slider 26 can only perform linear reciprocating motion along the axial direction of the screw rod 25. At the same time, the adjusting slider 26 is connected to the inner end (root) of the fan blade 23, which can drive the fan blade 23 to perform linear reciprocating motion along the radial direction within the inner cavity of the mounting post 22, thereby achieving the telescopic effect of the fan blade 23 relative to the mounting post 22. With this arrangement, when the fan control module 61 needs to control the telescopic movement of each fan blade 23, it only needs to send a corresponding control command to the control terminal of the auxiliary drive motor 24, which drives the screw rod 25 and the adjusting slider 26 to move. The threaded transmission has high control accuracy and can accurately control the telescopic position of each fan blade 23. It should be noted that, in order to avoid the influence of high-speed movement, the telescopic position adjustment of the fan blade 23 is generally performed under a stationary state.

[0058] Generally, considering that the root of the fan blade 23 is generally embedded in the mounting column 22 in an inclined direction, in order to improve the stability of the telescopic movement of the fan blade 23, in this embodiment, two sets of auxiliary drive motors 24, screw rods 25 and adjustment sliders 26 are provided at the same time, and are respectively located at the two ends of the root of the fan blade 23, so as to simultaneously drive the two ends of the root of the fan blade 23 to perform radial telescopic movement.

[0059] In addition, in order to prevent the fan blades 23 from extending too far out of the inner cavity of the mounting column 22 and causing instability, this embodiment also provides a limit plate at the opening of the inner cavity of the mounting column 22, so that the inner end T-shaped structure of the root of the fan blade 23 of the limit plate forms an abutment limit, thereby limiting the maximum extension distance of the fan blade 23.

[0060] Furthermore, considering that the output shaft of the main drive motor 21 is typically embedded in the axis center of the mounting post 22, in order to further reduce the noise generated by the operation of the cooling fan 2, in this embodiment, a silent bearing is installed at the axis center of the mounting post 22, and the output shaft of the main drive motor 21 is mounted via this silent bearing. This arrangement not only ensures the normal rotational movement of the output shaft of the main drive motor 21, but also reduces friction noise when the main drive motor 21 is running at high speed.

[0061] Taking into account that the noise generated by the cooling fan 2 during operation is mainly aerodynamic noise, in order to optimize the aerodynamic performance of the cooling fan 2 and reduce the aerodynamic noise, this embodiment adds a fan blade 23 optimization module to the controller 6. Specifically, the fan blade 23 optimization module is a separate operation module, which is mainly used to model the fan blade 23 through virtual modeling software, and then simulate and optimize the shape of the fan blade 23, especially the outer edge shape of the fan blade 23, through simulation test software to improve the outer edge shape of the fan blade 23, thereby enhancing the aerodynamic performance of the fan blade 23 and reducing the noise generated by the fan blade 23. The output results of the fan blade 23 optimization module are reflected in the actual product, and the product can be updated during the production and manufacturing stage, or the fan blade 23 on the mounting column 22 can be disassembled and replaced at a later stage.

[0062] In addition, considering that a large amount of dust or impurities may accumulate in the air ducts within the chassis 1 during long-term use, this may lead to a decrease in heat dissipation efficiency and an increase in noise. To address this, in this embodiment, the controller 6 also includes a dust cleaning control module 63. Specifically, the dust cleaning control module 63 maintains a signal connection with the control end of the main drive motor 21 and is mainly used to send control instructions to the control end of the main drive motor 21 according to a preset cycle or preset frequency, causing the main drive motor 21 to reverse, thereby utilizing the reverse motion of the main drive motor 21 to generate a reverse airflow within the server, thereby causing the reverse airflow to blow away dust, impurities, and other foreign matter attached to the inner wall of the chassis 1 or the surface of the server components. This helps to improve heat dissipation efficiency and reduce noise while keeping the power of the cooling fan 2 unchanged.

[0063] Furthermore, in order to improve the dust cleaning effect, this embodiment also adds a shaking head motor to the heat dissipation fan 2. Specifically, there are multiple shaking head motors at the same time, and the output shaft of each shaking head motor is respectively connected to the body of each heat dissipation fan 2, which is mainly used to drive each heat dissipation fan 2 to perform horizontal rotation or swing as a whole, thereby adjusting the direction or blowing direction of each heat dissipation fan 2. At the same time, each shaking head motor maintains a signal connection with the dust cleaning control module 63. With such a configuration, when a dust cleaning operation is required, the dust cleaning control module 63 sends a control instruction to each shaking head motor at the same time, so that each shaking head motor runs separately, and controls each heat dissipation fan 2 to change its original direction, such as the directions of two adjacent heat dissipation fans 2 are at a certain angle, etc., so that the airflows blown out by each heat dissipation outlet collide violently in the chassis 1, thereby forming violent turbulence, thereby enhancing the dust cleaning effect.

[0064] As shown in FIG6 , FIG6 is a schematic diagram of the specific structure of the phase change air guide cover 7 .

[0065] In addition, considering that the various server components are scattered in various locations within the chassis 1, in order to ensure that the heat dissipation airflow generated by the cooling fan 2 can pass through the various server components smoothly, in this embodiment, the phase change air guide cover 7 is specifically installed in the chassis 1. The overall structure is similar to that of a conventional air guide cover, mainly including a cover body 71, a heat dissipation channel 72 and a phase change plate 73.

[0066] The cover body 71 is the main structure of the phase change air guide cover 7 and is usually a rectangular frame structure.

[0067] The heat dissipation channel 72 is opened on the cover body 71, and generally multiple channels can be opened at the same time to separate the cold air flow formed by the heat dissipation fan 2 into multiple streams, and guide each stream of cold air flow to the target server component respectively, while dissipating heat for each server component.

[0068] Phase change plate 73 is positioned within heat dissipation channel 72, with its bottom surface covering the top surface of the corresponding server component. It is primarily used to directly absorb heat from the server component, similar to a heat conducting plate. Phase change plate 73 also has a cavity within it, which contains a certain amount of coolant. This coolant is a phase change material, such as fluorocarbons, mineral oils, synthetic oils, silicone oils, water, and ethylene glycol. It can absorb large amounts of heat to produce a phase change, forming a gas, or release large amounts of heat to produce a reverse phase change, forming a liquid.

[0069] With this configuration, after the phase change plate 73 absorbs heat from the server components, the heat is absorbed by the coolant, which then undergoes a phase change to form a gas. This gas rises to the top of the phase change plate 73, where it releases the heat to the outside world through natural heat dissipation or is carried away by the cold air within the heat dissipation channel 72. This causes the gaseous coolant to re-phase into a liquid and fall back to the top of the phase change plate 73, thus continuing the cycle. Compared to air guides that simply direct the cold air flow, the phase change air guide 7 in this embodiment not only guides the cold air flow and reduces airflow noise, but also enhances the heat dissipation efficiency of the server components.

[0070] Furthermore, in this embodiment, a plurality of heat dissipation fins 74 are vertically provided on the top of the phase change plate 73, thereby greatly increasing the heat exchange area between the top of the phase change plate 73 and the outside air or the cold air flow through each heat dissipation fin 74, thereby increasing the heat release rate of the gaseous coolant, accelerating the reverse phase change process of the gaseous coolant, and generally improving the heat dissipation efficiency of the phase change heat dissipation. Similarly, since the cold air flow usually also flows through the side of the phase change plate 73 at the same time, the heat dissipation fins 74 can also be provided on the side of the phase change plate 73. Of course, the heat dissipation fins 74 can be provided on the top and side of the phase change plate 73 at the same time. At the same time, in order to avoid obstruction to the cold air flow, in this embodiment, the arrangement direction of each heat dissipation fin 74 on the phase change plate 73 is specifically the extension direction of the heat dissipation channel 72, so that the cold air flow can flow along the gap between two adjacent heat dissipation fins 74.

[0071] Considering that the real-time power of each server component is usually different, that is, the heat generation and heat dissipation requirements of each server component are different, this embodiment adds an adjustable wind shield 75 to the phase change air guide cover 7. Specifically, the adjustable wind shield 75 is set at the air inlet position of each heat dissipation channel 72 to block the air inlet of each heat dissipation channel 72, and the adjustable wind shield 75 is also rotatably connected to the cover body 71, and can flip in the air inlet of the heat dissipation channel 72, thereby changing the opening of the air inlet of the corresponding heat dissipation channel 72, that is, the air inlet area, and thus adjusting the air inlet flow rate of each heat dissipation channel 72. With this arrangement, for a server component with a larger heat generation, the opening of the air inlet of the heat dissipation channel 72 corresponding to the server component can be increased, and vice versa.

[0072] Furthermore, in order to achieve precise control of the opening of the air inlet of each heat dissipation channel 72, this embodiment adds a windshield motor 76 to the phase change air guide cover 7. Accordingly, the temperature detection module 3 specifically includes multiple temperature sensors 31, and the controller 6 also includes an air volume control module 64. Specifically, the windshield motor 76 is embedded in the cover body 71 or connected to a position outside the cover body 71, and the output shaft of the windshield motor 76 is connected to the side wall of the corresponding adjustable windshield plate 75, mainly used to drive the adjustable windshield plate 75 to perform a flipping movement in the air inlet of the corresponding heat dissipation channel 72, thereby changing the opening of the air inlet of the heat dissipation channel 72. Each temperature sensor 31 is used to detect the temperature of its corresponding server component and feed back the detection value to the air volume control module 64 in real time. In this way, the detection value of the temperature detection module 3 is actually the average value of the detection values ​​of each temperature sensor 31. The air volume control module 64 maintains a signal connection with each temperature sensor 31, and is mainly used to control the working state of the corresponding windshield motor 76 according to the detection value of each temperature sensor 31, so as to adjust the flip angle of the corresponding adjustable windshield 75, and then control the opening of the air inlet of the corresponding heat dissipation channel 72 to achieve air inlet flow adjustment, thereby ensuring that the cooling capacity allocated to each server component matches its heat dissipation requirements.

[0073] In addition, to facilitate precise power regulation of server components, in this embodiment, the controller 6 also includes a power management module 65. Specifically, the power management module 65 maintains a signal connection with the server's power controller 6 and is primarily used to control the frequency and / or voltage and other electrical parameters of the processor chips in each server component based on the load demand obtained by the power consumption detection module 5. With this configuration, the power management module 65 can precisely control the power of the processor chips in the server components by controlling the electrical parameters of the processor chips in the server components, thereby improving the accuracy of power control over the entire server component. Furthermore, the power management module 65 can also implement a dynamic power management strategy, thereby causing the server to enter energy-saving mode when the load demand is low, thereby significantly reducing the speed of the cooling fan 2 and simultaneously reducing noise and energy consumption.

[0074] In some practical application embodiments, the controller may generate a power adjustment instruction and perform the following operations according to the power adjustment instruction:

[0075] 1. Monitoring power data: The controller first obtains the current power data of each server component, including but not limited to the power consumption of the CPU, memory, storage devices, and network interfaces.

[0076] 2. Generate power adjustment instructions: Based on the preset power management strategy and the currently acquired power data, the controller generates power adjustment instructions. These instructions include the target power value, that is, the minimum operating power data.

[0077] 3. Update memory power data: The controller updates the current power data of the memory modules to the lowest operating power by adjusting the memory power management settings. For example, this can be achieved by reducing the memory frequency or switching some memory modules to low-power mode.

[0078] 4. Adjust processor power: The controller transmits power adjustment instructions to the CPU, instructing its power management unit (PMU) to perform dynamic voltage and frequency scaling (DVFS), reducing the processor's operating frequency and voltage to reduce power consumption.

[0079] 5. Manage storage device power: The controller instructs the storage device (such as a hard disk or solid-state drive) to enter a low-power mode, such as standby mode or hibernation mode, through a command interface, and updates its current power data to the lowest operating power data.

[0080] 6. Regulating network interface power: The controller manages the power of the network interface and adjusts its power settings, for example, by reducing the activity frequency of the network port or shutting down unused ports to reduce power consumption.

[0081] 7. Recording and Monitoring: After performing power adjustments, the controller records the power data and adjustment status of each server component and continuously monitors this data to ensure that each component operates at the lowest power consumption state while maintaining the necessary system performance.

[0082] Through the above specific implementation, the controller can effectively adjust the current power of the server component to the corresponding minimum operating power, thereby optimizing energy utilization efficiency.

[0083] In a specific embodiment of the noise detection module 4, the noise detection module 4 primarily includes a plurality of noise detectors 41, each of which is disposed on an inner wall of the chassis 1, etc., to simultaneously detect noise intensity at various locations within the chassis 1. Accordingly, the detection value of the noise detection module 4 is actually the average of the detection values ​​of the noise detectors 41.

[0084] To further reduce internal noise in the chassis 1, this embodiment incorporates a sound insulation panel 8. Specifically, the panel 8 is located on the inner wall of the chassis 1, or on the sidewalls, front and rear surfaces of the cooling fan 2, or in both locations. Typically, the panel 8 is made of a material such as sound-absorbing cotton, primarily to absorb noise within the chassis 1. Of course, the panels 8 installed on the front and rear surfaces of the cooling fan 2 also require mesh holes to ensure ventilation.

[0085] Furthermore, to improve the noise absorption effect of the sound insulation panels 8, in this embodiment, the controller 6 also includes a sound insulation optimization module 66. Specifically, the sound insulation optimization module 66 is primarily used to simulate the installation position of each sound insulation panel 8 within the chassis 1 using virtual modeling software, thereby optimizing the specific installation position and number of each sound insulation panel 8 within the chassis 1 through simulation testing, thereby enhancing the noise reduction performance of the sound insulation panel 8 in the actual product.

[0086] The following is a specific example to illustrate the relationship between the control units in solving technical problems.

[0087] 1. Noise Detection Module: This module monitors the noise level in the server and adjusts the fan speed as needed to maintain acceptable noise levels. This module is related to other modules because if the server temperature is too high, the fans will need to speed up to cool the system, which may increase noise.

[0088] 2. Power Consumption Detection Module: This module monitors the server's energy consumption and adjusts hardware power consumption as needed to optimize energy efficiency. This module is related to the temperature detection module, as excessive power consumption can cause temperatures to rise, requiring increased fan speed or other cooling measures.

[0089] 3. Fan Control Module: The fan control module manages the server's fans, adjusting fan speed based on temperature and other parameters to maintain a suitable temperature. It is closely related to the noise detection module and the power consumption detection module, as fan operation not only affects noise levels but also power consumption and temperature.

[0090] 4. Power Management Module: The Power Management Module manages the server's power supply, adjusting power supply based on load and other factors to ensure stable system operation. It is closely related to the Power Control Unit because it adjusts power output based on power consumption requirements.

[0091] 5. Temperature Detection Module: This module monitors the temperature of various server components and adjusts fan speeds or other measures as needed to maintain temperatures within a safe range. It is related to other modules because excessive temperatures can lead to increased power consumption, faster fan speeds, and increased noise.

[0092] 6. Server Controller: The server controller is the hub of the entire system, responsible for coordinating communication and collaboration between various control units to ensure server stability, performance, and efficiency. It works closely with other modules to ensure the server can operate effectively under various circumstances.

[0093] Overall, these control modules form a tightly interconnected system within the server. Their collaboration effectively solves various technical problems and ensures server performance, stability, and reliability. Each of these modules plays a key role within the server, working together to ensure efficient and stable operation. The noise detection module manages the noise generated by the server, while the power consumption detection module monitors and manages the server's energy consumption. The cooling fan ensures that the internal temperature of the server remains within a safe range, working closely with the temperature detection module. The power management module ensures a stable and reliable power supply to the server. Finally, the server master controller coordinates and manages the operation of all these modules (units) so that the server system can work together effectively to ensure performance and stability. Therefore, they are closely intertwined, working together to solve technical problems, rather than simply operating independently.

[0094] This embodiment also provides a server, which mainly includes a chassis 1 and a heat dissipation control system arranged in the chassis 1. Since the heat dissipation control system adopts all the technical solutions of the above-mentioned embodiments of the aerodynamic noise and heat dissipation optimization control system, the server provided by this embodiment also has all the technical effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.
