Description

Technical Field

[0001] The present invention relates to the field of servers, and in particular to a power supply, a server, and a temperature adjustment method and device. Background Art

[0002] A server's power supply is a critical component, primarily responsible for providing stable power to various components within the server (such as the motherboard, CPU, and memory). To ensure effective heat dissipation during operation, the server is typically equipped with a fan to dissipate heat from various components. A separate fan is also installed within the power supply module to dissipate heat from various modules within the power supply (such as the input module, output module, and control circuit). However, when two fans are installed within a server, the fan inside the power supply is susceptible to airflow interference from the server fan, leading to the risk of fan reverse rotation. Fan reverse rotation can increase friction between the fan blades and the motor shaft, potentially damaging the fan. Once a fan is damaged, the power supply module's heat dissipation capacity is significantly reduced, potentially causing overheating, which can damage the power supply module or cause server downtime.

[0003] To solve this problem, the current solution is to disassemble the power module and replace the damaged fan inside, but this not only increases maintenance costs, but also consumes a lot of manpower and time. Summary of the Invention

[0055] The core of the present invention is to provide a power supply, server, temperature adjustment method and device, which can achieve efficient heat dissipation of the power supply and motherboard with only one fan, avoiding the airflow interference and reversal risk caused by the setting of additional fans; when any functional module is abnormal, the wind shield is closed to block the interference of external airflow on the fan, and the fan stops rotating at the same time, thereby avoiding friction damage caused by fan reversal, reducing maintenance costs, and improving system reliability and heat dissipation efficiency.

[0056] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0057] First, as Figure 1 As shown, the present application provides a power supply, which is applied to a server. The server also includes a mainboard, a fan 11 and a windshield 12, and the power supply includes at least two functional modules; the fan 11 is arranged at the first end of the air duct, and the windshield 12 is arranged at the second end of the air duct. The fan 11 is adjacent to the mainboard in the server, and the overall input ends of at least two functional modules are connected to the power supply, and the overall output ends of at least two functional modules are respectively connected to the power supply end of the mainboard and the power supply end of the fan 11, and at least two functional modules are evenly distributed on both sides of the air duct; the power supply is used to convert the power supply through at least two functional modules to provide power for the mainboard; the windshield 12 is used to adjust its own opening and closing angle according to the first preset instruction when the status of all functional modules is normal, and to close when the status of any functional module is abnormal; the fan 11 is used to adjust its own speed according to the second preset instruction when the status of all functional modules is normal to dissipate heat for the mainboard and the power supply, and to stop rotating when the status of any functional module is abnormal.

[0058] This power supply system design addresses the heat dissipation and safety issues of the server power supply and provides an intelligent air duct management, power module redundancy, and anomaly detection mechanism. The power supply includes at least two functional modules, and the overall function of all functional modules is to convert the input power signal to provide a stable output voltage to provide the required power for the server motherboard and fan 11. These functional modules are usually DC-DC converters that can convert the input power supply (such as AC power) to Figure 1 The 230Vac (also known as 230V alternating current) is converted into a DC voltage suitable for the needs of each component (such as providing processor voltage for the motherboard, providing drive voltage for the fan 11, etc.), Figure 1 12Vdc in the example).

[0059] The integrated input terminals of all functional modules are connected to the server's power supply. This input power may be AC ​​power from an external outlet, which enters the power system through a power adapter for conversion. The integrated output terminals of all functional modules are connected to the power supply terminals of the motherboard and fan 11, respectively. The motherboard requires a variety of different voltages (such as 3.3V, 5V, 12V, 54V, etc.) to drive different components, while fan 11 requires a stable power supply to control its speed. The functional modules in the power supply system meet these requirements by providing different voltage outputs.

[0060] The air duct in the server is designed for efficient heat dissipation. Fan 11 is located at the first end of the duct, typically near the power supply and motherboard, to effectively dissipate heat during server operation. Fan 11 removes heat through airflow, ensuring that the motherboard and power supply do not malfunction due to overheating during operation.

[0061] Placing the fan 11 close to the motherboard ensures that the heat generated by the motherboard during operation, especially under high load conditions, can be quickly removed by the fan 11. The speed of the fan 11 can be automatically adjusted according to the motherboard temperature or other system parameters.

[0062] Windshield 12, located at the second end of the air duct, regulates the direction and volume of airflow. When the functional module is operating normally, windshield 12 adjusts its opening and closing angles according to the first preset instructions, optimizing airflow distribution and ensuring smooth airflow throughout the system for efficient heat dissipation.

[0063] In addition, the power supply is designed with redundancy mechanisms and fault detection capabilities, and can take countermeasures when any functional module fails to ensure the safety and stability of the system.

[0064] Each functional module can determine whether it is operating normally by monitoring current, voltage, or other parameters. If a functional module experiences an abnormality, appropriate safety measures are immediately implemented. At this point, the windshield 12 closes to prevent external airflow from interfering with the fan 11, and the fan 11 stops rotating. This effectively prevents friction damage caused by incorrect or reverse rotation of the fan 11, thereby reducing maintenance costs.

[0065] The principle of the wind shield 12 is: when all functional modules are working normally, the wind shield 12 will be adjusted according to the preset angle to ensure uniform distribution of airflow and improve heat dissipation efficiency; but when any functional module fails, the wind shield 12 will quickly close, cutting off the external air circulation, preventing unstable airflow from affecting the normal operation of the fan 11, and ensuring that the fan 11 is not disturbed.

[0066] Fan 11 not only plays a role in heat dissipation, but is also closely related to the operating status of the server. Its rotation speed is intelligently adjusted according to the temperature conditions of the power supply and motherboard, as well as the working status of the functional modules. When all functional modules are working normally, fan 11 adjusts its own rotation speed according to the second preset instruction to adapt to the heat dissipation requirements of the system. For example, when the load on the motherboard and power supply is high, the speed of fan 11 will increase, increasing the airflow to take away more heat. Conversely, when the load is low, the speed of fan 11 will slow down, thereby reducing noise and saving energy. If any functional module malfunctions, fan 11 will stop rotating. This design effectively avoids damage to the hardware caused by the reverse rotation of fan 11, especially the reverse rotation of fan 11 in the power supply system may cause current instability, thereby damaging fan 11 itself or causing other electrical failures.

[0067] This embodiment achieves efficient heat dissipation and highly secure operation through intelligent air duct management, fault detection, and response mechanisms. By intelligently adjusting the speed of fan 11 and the angle of windshield 12, not only is heat dissipation optimized, but system redundancy is also enhanced. Most importantly, in abnormal situations, airflow to malfunctioning modules is automatically cut off, preventing hardware damage caused by reverse rotation of fan 11. This significantly reduces maintenance costs and improves overall system reliability and heat dissipation efficiency.

[0068] like Figure 1 and Figure 2 As shown, as an optional embodiment, the functional module includes an input module 13, a power conversion module and an output module 15; the input end of the input module 13 is connected to the power supply, the output end of the input module 13 is respectively connected to the input end of the power conversion module and the power end of the windshield 12, and the output end of the output module 15 is respectively connected to the power end of the fan 11 and the power end of the mainboard; the input module 13 is used to filter the power supply and provide power for the windshield 12; the power conversion module is used to convert the filtered power supply to obtain a DC power supply; the output module 15 is used to output the DC power supply to power the fan 11 and the mainboard.

[0069] In this embodiment, the power system works in coordination with three functional modules: an input module 13 , a power conversion module, and an output module 15 , to achieve stable power supply and efficient heat dissipation management.

[0070] Specifically, the input module 13 receives power from an external source (usually an AC power source, Figure 1The input power is filtered by a built-in filter circuit. This step is to remove clutter, noise and voltage fluctuations in the input power to ensure the stability of the power supply and avoid interference with subsequent circuits and load devices. Specifically, the input circuit can include an electromagnetic interference protection circuit and a surge suppression circuit to suppress differential and common mode noise of the power supply and limit the size of the surge current. The filtered power supply (in Figure 1 The 230Vac output by the input module 13 not only provides input power to the power conversion module, but also provides power to the windshield 12 to ensure that the windshield 12 can normally adjust its opening and closing angle to optimize the airflow during the operation of the power system.

[0071] The filtered power enters the power conversion module. The main task of the power conversion module is to convert the input power signal (usually AC) into a DC power suitable for internal use in the system (such as 12V, 54V, etc.) Figure 1 12Vdc / 54Vdc in the example). A power conversion module typically includes multiple functional components, such as rectification, filtering, and voltage regulation, capable of converting AC power into a variety of stable DC voltages to meet the different power requirements of the motherboard and fan 11. The power conversion module not only converts power to provide a stable DC voltage but also dynamically adjusts the output voltage and current based on changes in system load and power requirements to maintain efficient operation of the entire system.

[0072] DC power is distributed through output module 15. Output module 15 is responsible for further conditioning the DC power from the power conversion module and outputting it to fan 11 and the motherboard. Fan 11's power requirement primarily drives its motor, regulating its speed and helping dissipate system heat. The motherboard, on the other hand, requires a variety of voltages to drive core components such as the processor and memory. Based on the actual power requirements of fan 11 and the motherboard, output module 15 ensures a stable and appropriate power supply to both, thereby ensuring the proper functioning of the motherboard and fan 11.

[0073] Overall, this embodiment ensures stable and adaptable power supply. Input module 13 filters the power supply, which is then converted to the required DC power by the power conversion module. Finally, output module 15 precisely distributes the power, ensuring sufficient power for the fan 11 and motherboard. The system also utilizes the power supply from the air shield 12, which, combined with its regulation function, optimizes airflow and heat dissipation, providing more efficient and stable power support for server operation.

[0074] like Figure 2As shown, as an optional embodiment, it also includes: a first control module 18, whose output end is connected to the communication end of the mainboard through the output module 15, and whose output end is connected to the control end of the fan 11; the output module 15 is also connected to the sampling end of the fan 11, and the output module 15 is also used to transmit communication data between the first control module 18 and the mainboard, and to transmit the sampling information of the fan 11 to the mainboard; the first control module 18 is used to control the rotation speed of the fan 11 and the opening and closing angle of the wind shield 12 according to the temperature acquisition parameters when the mainboard does not issue a control instruction, and to control the rotation speed of the fan 11 and the opening and closing angle of the wind shield 12 according to the control instruction when the mainboard issues a control instruction.

[0075] In this embodiment, the system introduces a first control module 18 to further enhance the intelligent control of the fan 11 and the windshield 12 and optimize the system's heat dissipation management. The working principle of the entire power supply system can be divided into two main stages: mainboard control and automatic adjustment.

[0076] During the automatic adjustment phase, meaning when the first control module 18 does not receive explicit control instructions from the mainboard, it automatically adjusts the fan 11 speed and the windshield 12 opening angle based on temperature data (e.g., temperature data from various internal server components). Temperature sensors monitor the temperature of the mainboard, fan 11, and other key components in real time and feed this data back to the first control module 18. By analyzing this temperature data, the first control module 18 determines the current system cooling requirements and adjusts the fan 11 speed and windshield 12 angle according to predefined logic. For example, when temperatures are high, the system automatically increases the fan 11 speed and adjusts the windshield 12 angle to ensure smooth airflow and enhance cooling. When temperatures are low, the fan 11 speed decreases, and the windshield 12 may be adjusted to a smaller angle to reduce energy consumption and noise.

[0077] During the motherboard control phase, that is, when the motherboard sends control instructions to the first control module 18, the first control module 18 will adjust the speed of the fan 11 and the opening and closing angle of the windshield 12 according to these instructions. These instructions are usually based on a comprehensive judgment of multiple factors such as system load, ambient temperature, and heat dissipation requirements. The motherboard can use control instructions to fine-tune the fan 11 and windshield 12 to achieve more efficient heat dissipation, reduce noise, or improve system stability. For example, when the motherboard detects that the processor load is too high or the device temperature is too high, it may issue instructions to require the fan 11 to speed up and the windshield 12 to open a wider angle to improve air flow.

[0078] Furthermore, the first control module 18 transmits sampled information collected by the temperature sensor (such as fan 11 speed, air duct temperature, mainboard current and voltage, etc.) to the mainboard via the output module 15, and also provides feedback on the operating status of the fan 11. This allows the mainboard to make dynamic decisions based on real-time data, further optimizing the power system's operating status. This data exchange mechanism enables more precise adjustment of cooling strategies, ensuring that key components such as the mainboard and power supply maintain optimal operating temperatures under all conditions.

[0079] In summary, when no control commands are received, the first control module 18 intelligently adjusts the operating status of the fan 11 and windshield 12 based on automatically collected temperature parameters. Upon receiving control commands from the mainboard, it precisely adjusts these components to ensure heat dissipation and system stability. Through real-time data transmission and a flexible control mechanism, the entire system dynamically adapts to actual load and environmental conditions, thereby improving system efficiency, reliability, and energy utilization.

[0080] As an optional embodiment, when the mainboard does not issue a control instruction, the speed of the fan 11 and the opening and closing angle of the wind shield 12 are regulated according to the temperature collection parameters, including: when the mainboard does not issue a control instruction and the power is turned on, controlling the wind shield 12 to open, and adjusting the opening angle of the wind shield 12 to a preset angle, and adjusting the speed of the fan 11 according to the temperature collection parameters.

[0081] In this embodiment, when the motherboard (specifically the BMC (Baseboard Management Controller)) is not issuing control commands, the server maintains normal operation and heat dissipation efficiency through automatic adjustments. Based on real-time temperature data, the system automatically adjusts the speed of fan 11 and the opening and closing angle of air shield 12 to ensure optimal heat dissipation and energy efficiency management under different server operating conditions.

[0082] When the system is powered on and the motherboard does not issue any control instructions, it automatically adjusts according to the default temperature collection parameters. First, the control system ensures that the windshield 12 is open and adjusts it to the preset opening and closing angle. The opening angle of the windshield 12 is usually set to an angle that can maximize airflow to help the system dissipate heat quickly. After the windshield 12 is opened, the speed of the fan 11 is automatically adjusted according to the data collected by the temperature sensor. If the internal temperature of the server is high, the speed of the fan 11 will be increased to enhance heat dissipation; if the temperature is low, the speed of the fan 11 will be appropriately reduced to reduce energy consumption and noise.

[0083] As an optional embodiment, after controlling the wind shield 12 to open and adjusting the opening angle of the wind shield 12 to a preset angle, it also includes: obtaining the current opening angle of the wind shield 12, and determining whether the current opening angle is the preset angle; if so, entering the step of adjusting the speed of the fan 11 according to the temperature acquisition parameters, otherwise controlling the wind shield 12 prompt device to issue a preset prompt message.

[0084] After the windshield 12 is opened and adjusted to the preset angle, the system further checks whether the current opening and closing angle of the windshield 12 meets the preset standard. If the current angle is consistent with the preset angle, the system proceeds to the next step, adjusting the speed of the fan 11 based on the collected temperature data to ensure cooling efficiency and optimal energy utilization. If the current angle does not reach the preset angle, the system controls the windshield 12's prompt device to issue a preset prompt message (the windshield 12 prompt device can be an indicator light), prompting the user or maintenance personnel to perform necessary inspections or adjustments. This mechanism ensures that the system maintains optimal cooling conditions while optimizing airflow in the air duct.

[0085] As an optional embodiment, when the mainboard does not issue a control instruction, the speed of the fan 11 and the opening and closing angle of the wind shield 12 are regulated according to the temperature collection parameters, including: when the mainboard does not issue a control instruction and the power is off, the wind shield 12 is controlled to close, and the fan 11 is controlled to stop rotating within a preset time period.

[0086] Controlling the operation of the air shield 12 and fan 11 during a power outage is primarily designed to prevent reverse rotation of the fan 11 due to external airflow. Upon power failure, the system first shuts off the airflow by closing the air shield 12. Closing the air shield 12 prevents external airflow from entering the air duct, effectively preventing it from causing a reverse rotation of the fan 11. Closing the air shield 12 not only reduces airflow interference but also isolates the fan 11 from the effects of environmental fluctuations. In addition to closing the air shield 12, the system also controls fan 11 to stop rotating within a preset time period. This strategy crucially ensures that fan 11 does not rotate when the power is off. Even if external airflow persists, it does not create a force that could cause the fan 11 to rotate in reverse. By stopping fan 11, the system effectively prevents reverse rotation of the fan 11 due to external factors, thereby eliminating the risk of reverse rotation.

[0087] As can be seen, in this embodiment, when the power is turned off, by closing the air baffle 12 and stopping the fan 11, the fan 11 is prevented from rotating in the reverse direction due to external airflow when no power is supplied. This control strategy prevents potential damage caused by the reverse rotation of the fan 11, extending the service life of the device and reducing the risk of poor heat dissipation or hardware damage caused by reverse rotation.

[0088] As an optional embodiment, the first control module 18 is also used to monitor the signal connectivity between the mainboard and itself. When the mainboard is connected to itself and no control instructions are issued, or when the mainboard is disconnected from itself, it enters the step of regulating the speed of the fan 11 and the opening and closing angle of the wind shield 12 according to the temperature collection parameters.

[0089] In this embodiment, the first control module 18 not only regulates the speed of the fan 11 and the opening and closing angle of the air shield 12 based on the collected temperature parameters, but also monitors the signal connectivity between the motherboard (particularly the BMC on the motherboard) and the first control module 18. This monitoring mechanism ensures that the system can respond appropriately under different operating conditions, ensuring normal heat dissipation and efficient operation of the server.

[0090] Specifically, the first control module 18 continuously monitors the signal connection status between the mainboard and itself. This monitoring typically focuses on key communication signals such as data transmission and the transmission of control commands between the mainboard and the first control module 18. If the signal connection between the mainboard and the first control module 18 is normal (i.e., the mainboard and the control module remain connected and no control commands are issued), the module automatically controls the fan 11 speed and the windshield 12 opening and closing angle based on the collected temperature parameters. If the signal connection is disconnected, or if no control commands are received from the mainboard, the first control module 18 will also initiate the same automatic adjustment mechanism.

[0091] Under normal circumstances, the BMC or motherboard may issue control instructions to instruct the first control module 18 on how to adjust the fan 11 speed and the windshield 12 angle when the preset control requirements are met. Typically, the BMC determines the fan 11 speed and the degree of air duct opening and closing based on internal workload, temperature sensor data, or other operating conditions. However, if for some reason the motherboard fails to issue instructions (e.g., due to an inoperative BMC, communication failure, or other issues), or if the motherboard loses its connection to the first control module 18, the system must continue to operate and maintain proper cooling performance.

[0092] If the first control module 18 detects a disconnected signal between the motherboard and the server, or detects a lack of control commands, it automatically adjusts the fan 11 speed and the windshield 12 angle based on real-time temperature data. For example, as the server's temperature rises, the first control module 18 automatically increases the fan 11 speed to enhance heat dissipation and adjusts the windshield 12 angle to optimize airflow. When the temperature drops, the first control module 18 decreases the fan 11 speed and adjusts the windshield 12 angle to reduce energy consumption and noise.

[0093] The core purpose of this embodiment is to ensure that temperature adjustments are made according to actual temperature requirements in all situations, independent of motherboard control commands. This self-regulation mechanism is particularly important in the event of motherboard failure, signal loss, or malfunction. It ensures that the server can maintain normal operation even when unable to receive external control commands, preventing overheating or other hardware damage due to poor heat dissipation.

[0094] In summary, this embodiment, by monitoring the signal connectivity between the mainboard and first control module 18, enables the system to automatically adjust the fan 11 speed and the windshield 12 opening and closing angle based on temperature-collected parameters when the mainboard fails to issue control commands (whether due to signal disconnection or other reasons). This mechanism enables the system to maintain cooling performance even in the absence of mainboard control commands, ensuring long-term stable operation of the server, reducing the risk of uncontrolled cooling due to mainboard problems, and improving the system's fault tolerance and reliability.

[0095] like Figure 2 As shown, as an optional embodiment, the output module 15 includes: an acquisition circuit 21, whose input end is connected to the sampling end of the fan 11, and is used to sample the status information and speed of the fan 11 to obtain sampling information; a signal circuit 23, whose first end is respectively connected to the output end of the acquisition circuit 21 and the output end of the first control module 18, and whose second end is connected to the mainboard, and is used to transmit communication data between the first control module 18 and the mainboard, and to transmit the sampling information of the fan 11 to the mainboard; a power supply circuit 22, whose input end is connected to the output end of the power conversion module, and whose output end is respectively connected to the power end of the fan 11 and the power end of the mainboard, and is used to output DC power to power the fan 11 and the mainboard.

[0096] In this embodiment, the output module 15 primarily comprises three key components: an acquisition circuit 21, a signal circuit 23, and a power supply circuit 22. These components work together to ensure the system can stably transmit necessary communication data, provide continuous power to the fan 11 and motherboard, and monitor the operating status and speed of the fan 11.

[0097] The acquisition circuit 21 monitors the status of the fan 11 in real time, including its speed and operating status. Through this circuit, the system can obtain operational data about the fan 11, such as its current speed and workload, thereby ensuring the efficiency and stability of the fan 11 under various operating conditions. This sampled information is crucial for regulating the operation of the fan 11, particularly during temperature fluctuations or load fluctuations.

[0098] The signal circuit 23 is responsible for processing and transmitting communication data. It not only transmits the fan 11 status information acquired by the acquisition circuit 21 to the mainboard, but also enables bidirectional data exchange between the first control module 18 and the mainboard. Through the signal circuit 23, the mainboard can obtain the operating status of the fan 11 and decide whether to adjust the fan 11 speed. Furthermore, the signal circuit 23 transmits control signals from the first control module 18 to the mainboard, enabling coordinated control of the mainboard and fan 11.

[0099] The power supply circuit 22 ensures the entire system's power supply. Through this circuit, DC power is output from the power conversion module and efficiently distributed to the fan 11 and the motherboard, ensuring their continuous operation. The power supply circuit 22 provides stable power based on the power consumption requirements of the fan 11 and motherboard, ensuring the system's electrical stability and reliability.

[0100] Overall, these three components work together to ensure the orderly monitoring of fan 11's status, data transmission, and power supply, guaranteeing system thermal management and stable operation. When fan 11's status or temperature changes, output module 15 provides real-time data feedback and adjusts fan 11's speed, optimizing system cooling and adjusting power distribution based on the motherboard's needs. This process ensures efficient and stable system operation, reducing the risk of cooling failure and overheating.

[0101] like Figure 1 As shown, as an optional embodiment, the power conversion module includes: a power correction module 16, whose input end is connected to the output end of the input module 13, for correcting the power factor of the filtered power supply and converting the corrected power supply into a first DC power supply; a DC conversion module 17, whose input end is connected to the power correction module 16, for converting the first DC power supply into a second DC power supply, and the voltage of the first DC power supply is greater than the voltage of the second DC power supply.

[0102] In this embodiment, the power conversion module may include but is not limited to a power correction module 16 and a DC conversion module 17, which aims to ensure that the input power supply can meet the system's requirements for different voltages after processing, while improving the efficiency of power use.

[0103] The main task of the power correction module 16 is to correct the power factor of the input power supply. The power factor is an important indicator to describe the efficiency of the power system. It measures the ratio between the actual power (useful work) and the apparent power (total work). In the power system, due to the non-linear load, it often causes a low power factor, which in turn leads to waste of electric energy. The power correction module 16 adjusts the waveform of the input power supply to reduce reactive power and improve the power factor, so that the system can use electric energy more efficiently. After the power factor correction is performed, the input power is converted into a higher DC power supply, namely the first DC power supply ( Figure 1 Its voltage is higher, which provides suitable input conditions for subsequent voltage conversion.

[0104] The DC conversion module 17 converts the first DC power source after power correction into a second DC power source with a lower voltage ( Figure 1 12Vdc / 54Vdc in the example above) to meet the system's varying voltage requirements. Because the voltage of the first DC power supply is higher than that of the second DC power supply, DC conversion module 17 typically uses step-down conversion technology, such as a Buck converter, to reduce the voltage to the required value. This step-down process not only achieves voltage adaptation but also effectively regulates current, ensuring that the power supply provides a stable and reliable voltage output to the system.

[0105] Overall, the power conversion module achieves efficient utilization and stable output of input power through a two-stage conversion process: power factor correction and DC step-down conversion. Power correction ensures efficient conversion of input power, while DC conversion ensures that the system receives the appropriate voltage as needed, ensuring the normal operation of all system components while improving energy efficiency and stability.

[0106] As an optional embodiment, Figure 1 As shown, it also includes: a second control module 19, whose output end is connected to the parameter setting end of the power correction module 16, and is used to update the parameters in the power correction module 16 to the target parameters according to the input target parameters.

[0107] In this embodiment, the second control module 19 is used to update the parameters or firmware in the power calibration module 16 to ensure that the power supply achieves optimal performance and efficiency under different operating conditions. The second control module 19 is connected to the parameter setting terminal of the power calibration module 16, can receive input target parameters, and adjust or update the power calibration module 16 based on these parameters.

[0108] The performance of power correction module 16 is often affected by internal parameters (such as voltage and current regulation parameters, power factor regulation parameters, etc.). These parameters require timely adjustment based on varying input power conditions and system requirements. Second control module 19, by receiving target parameters, dynamically adjusts the internal settings of power correction module 16 to ensure the system maintains high efficiency and stability in various operating environments. The target parameters can be adjusted based on changes in power supply load, input voltage fluctuations, temperature changes, or other external environmental factors.

[0109] In addition to adjusting real-time parameters, the second control module 19 can also perform firmware updates. Firmware updates involve updating the operating logic or functional modules of the power correction module 16 by transferring new program code or configuration files. This is typically performed when the system needs to be upgraded, bugs need to be fixed, or new features need to be introduced. Firmware updates can enhance power management capabilities, improve power factor correction efficiency, and optimize overall system energy usage without replacing hardware.

[0110] Second control module 19 enables power calibration module 16 to flexibly adapt to different operating scenarios and requirements. For example, when power input conditions change, second control module 19 can update the settings of power calibration module 16 in real time based on the new target parameters, ensuring that the power supply system always operates optimally. This adaptability enables the power supply to operate stably despite various loads and input power fluctuations, maximizing energy efficiency.

[0111] Through regular parameter updates and firmware upgrades, the second control module 19 ensures that the power calibration module 16 always operates in an optimized state, preventing performance degradation or failures caused by outdated firmware or inappropriate parameter settings. By making adjustments remotely or locally, it enhances the intelligent management capabilities of the power system, thereby enhancing the system's stability, reliability, and long-term effectiveness.

[0112] In summary, in this embodiment, the second control module 19 ensures the flexibility and adaptability of the power correction module 16 by providing parameter and firmware update functions. This enables the power supply to adjust to varying input conditions, optimizing power factor correction and energy efficiency, maintaining efficient and stable system operation, and improving long-term system performance through firmware updates. This mechanism significantly enhances the power supply system's adaptability and intelligent management capabilities, helping to extend the life of the equipment and improve overall system reliability.

[0113] like Figure 1As shown, as an optional embodiment, it also includes: an auxiliary power supply module 14, whose input end is connected to the output end of the input module 13, and whose output end is connected to the input end of the output module 15, for converting the filtered power supply to obtain an auxiliary DC power supply, and the voltage of the auxiliary DC power supply is different from the voltage of the DC power supply output by the power conversion module.

[0114] In this embodiment, the auxiliary power module 14 provides an additional power output, called an auxiliary DC power supply. The voltage of this auxiliary DC power supply is different from the DC power supply voltage output by the main power conversion module. This design provides additional power support for the system, especially when the main power supply (i.e., the DC power output by the power conversion module) cannot meet specific load requirements.

[0115] At the input end of the system, the input module 13 first filters the external power supply to ensure that the noise and fluctuations in the power supply are effectively suppressed. This step provides a stable power supply foundation for subsequent power correction and power conversion. The input module 13 passes the filtered power supply to the auxiliary power supply module 14 as the input of the auxiliary power supply module 14. The auxiliary power supply module 14 receives the filtered power supply and converts it to generate an auxiliary DC power supply. The voltage value of the auxiliary DC power supply is different from the DC power supply voltage output by the main power conversion module, which means that the auxiliary power supply module 14 provides an independent power supply with a voltage different from the main power supply voltage. This design can meet the needs of specific modules in the system with different voltage requirements, such as sensors, control circuits or other small loads, without relying on the voltage of the main power supply.

[0116] The auxiliary DC power output by the auxiliary power module 14 is typically used to power system modules whose voltages don't match the main power supply voltage. By providing a voltage different from the main power supply, the auxiliary power module 14 can flexibly support devices with diverse voltage requirements. This is particularly helpful when the main power supply voltage isn't suitable for specific circuits or modules. For example, some low-power control modules or sensors may require a lower voltage (such as 3.3V), while the main power supply may output a higher voltage (12V or 54V). The auxiliary power supply can provide this low-voltage support.

[0117] Because the auxiliary power module 14 can operate independently and provide a voltage different from the main power supply, it adds a layer of power redundancy to the system, reduces the burden on the main power supply, and improves overall system reliability. Especially when certain critical modules require a constant voltage supply, the auxiliary power supply ensures that these modules always receive stable power, avoiding voltage instability caused by fluctuations in the main power supply or changes in load.

[0118] The output of the auxiliary power module 14 is transmitted to the output module 15 to provide the required voltage support. Based on the power requirements, the output module 15 transmits the power of the main power supply and the auxiliary power supply to the fan 11, the motherboard, and other modules requiring power support, thus ensuring the stable operation of the entire system under the condition of multiple voltage requirements.

[0119] In addition, the auxiliary power supply module 14 can also be used to supply power to the first control module 18 and the second control module 19 . The two control modules may be MCUs (Microcontroller Units).

[0120] In summary, the auxiliary power module 14 of this embodiment converts filtered power into an auxiliary DC power supply, distinct from the main power supply, providing an independent, adjustable voltage output to meet the independent voltage requirements of specific loads in the system. This design enhances the system's flexibility and adaptability, particularly when powering multiple modules with different voltage requirements. It also shares the burden of the main power supply, improving system stability and reliability.

[0121] like Figure 1 As shown, as an optional embodiment, the power correction module 16 and the DC conversion module 17 are arranged in sequence on the first side of the air duct; the input module 13, the auxiliary power supply module 14 and the output module 15 are arranged in sequence on the second side of the air duct.

[0122] In this embodiment, the power system components are arranged on both sides of the air duct to optimize heat dissipation and improve overall system efficiency. Specifically, the power correction module 16 and DC conversion module 17 are arranged on the first side of the air duct, while the input module 13, auxiliary power module 14, and output module 15 are arranged on the second side. This arrangement plays a significant role in improving the power system's heat dissipation performance, operational stability, and power management.

[0123] The power correction module 16 and DC conversion module 17 are primarily responsible for power factor correction and voltage conversion of the input power to ensure a stable and appropriate DC voltage is provided to the power supply system. These modules typically generate a high amount of heat, so they are placed on the first side of the air duct. This helps to centrally process the generated heat and remove it through the airflow of the duct. Placing them on the first side of the duct ensures that this heat is quickly removed by the airflow, preventing overheating from affecting the performance or life of the module.

[0124] The input module 13, auxiliary power module 14, and output module 15 are arranged on the second side of the air duct. The input module 13 receives and filters power from an external power source, the auxiliary power module 14 provides an independent auxiliary voltage output, and the output module 15 outputs DC power to the fan 11, motherboard, and other loads. These modules typically generate relatively little heat, so they can be placed on the second side of the air duct, separate from the high-power modules on the first side. This optimizes airflow distribution and prevents thermal interference between modules.

[0125] In addition, this arrangement can also reduce electromagnetic interference between different power modules within the system, because the positions of the power modules are more dispersed, which can achieve optimal airflow and electrical isolation.

[0126] Specifically, the power correction module 16 is at one end close to the outer edge of the server (close to the wind shield 12), and the DC conversion module 17 is at one end close to the inner side of the server (close to the motherboard or close to the fan 11); the input module 13 is at one end close to the outer edge of the server (close to the wind shield 12), and the output module 15 is at one end close to the inner side of the server (close to the motherboard or close to the fan 11).

[0127] In summary, by arranging the power correction module 16 and DC conversion module 17 on the first side of the air duct, and the input module 13, auxiliary power module 14, and output module 15 on the second side of the air duct, airflow and heat dissipation performance can be effectively optimized. This layout ensures that the heat of the high-power modules is quickly removed while preventing the impact of heat and electromagnetic interference on the low-power modules, thereby improving the stability and reliability of the system and ensuring that the power supply system can operate efficiently and stably under different loads.

[0128] In a second aspect, the present application provides a server comprising the aforementioned power supply, a fan, and a windshield, wherein the output terminal of the power supply is connected to the power terminal of the fan and the power terminal of the motherboard, respectively. For further information on the server, please refer to the aforementioned embodiment, and this application will not elaborate further here.

[0129] In a third aspect, the present application provides a temperature adjustment method, which is applied to the server as described above, and the method includes:

[0130] S11: Monitor the status of each functional module in the power supply and determine whether there is any functional module with an abnormal status.

[0131] In this step, a series of sensors and monitoring modules track the operating status of each functional module in the power supply in real time. Each functional module (such as the input module, power correction module, and DC converter module) may experience overheating, overload, voltage anomalies, or other performance issues. These abnormalities can affect system stability and efficiency. By monitoring these functional modules, the system can promptly detect abnormal conditions. Generally, the monitoring module collects key parameters such as temperature, current, and voltage from each functional module to determine its status. If a module parameter deviates from the normal range, the system will determine that the functional module has an abnormality. During this process, the control system analyzes and determines whether the power system is in normal operation based on the information provided by the sensors, and then decides whether to proceed to the next control step.

[0132] S12: When all functional modules are in normal state, the opening and closing angle of the windshield is adjusted according to the first preset instruction, and the speed of the fan is adjusted according to the second preset instruction to dissipate heat for the power supply and the motherboard.

[0133] This step is activated when the system detects that all functional modules are operating normally. At this point, the air deflector's opening and closing angle is adjusted according to the first preset command. The air deflector's function is to guide airflow and optimize the airflow path, thereby improving heat dissipation efficiency. The first preset command is typically an optimal angle automatically calculated based on system operating conditions (such as load and ambient temperature). Adjusting the air deflector's angle allows for better airflow to the power supply and motherboard, ensuring proper cooling of these critical components.

[0134] At the same time, a second preset command is used to adjust the fan speed. Fan speed control directly affects airflow intensity and heat dissipation efficiency. When the functional module is in normal operation, the fan speed may be adjusted based on the motherboard's temperature information or ambient temperature to ensure that the power supply and motherboard are always within the optimal temperature range. The goal of this process is to maintain system temperature balance through intelligent temperature control, avoid overheating, and ensure the safe operation of the power supply and motherboard.

[0135] S13: When the status of any functional module is abnormal, the windshield is controlled to close and the fan is stopped according to the second preset instruction.

[0136] This step is immediately initiated when the system detects an abnormality in the status of a functional module. This is a protective measure designed to prevent further damage or system instability caused by a fault or abnormality. In this case, the air baffle will close according to a second preset command. The purpose of closing the air baffle is to cut off external airflow interference, preventing the abnormal functional module from being further affected by external environmental factors, or to prevent additional heat accumulation caused by uneven airflow. In addition, the fan will also stop rotating to avoid problems such as fan reversal or friction, thereby protecting the fan from damage. Stopping the fan helps avoid airflow turbulence in abnormal conditions, which may cause additional thermal impact or electrical damage to other modules. Through these control measures, the system can ensure that the power supply system can effectively protect itself even in the event of an abnormality, while also avoiding damage to other hardware components.

[0137] Taken together, these steps form a closed-loop control system based on anomaly detection and temperature regulation. During normal system operation, the system dynamically adjusts the air shield and fan settings to ensure effective heat dissipation. If a functional module experiences an anomaly, the air shield is closed and the fan is stopped, preventing further problems from occurring and protecting system stability and hardware security. This intelligent temperature regulation method effectively improves the system's heat dissipation efficiency and enhances its ability to respond to sudden failures.

[0138] A specific implementation of the temperature adjustment method is as follows: Figure 4 As shown, at the beginning, the power is turned on, at this time the fan resumes automatic speed regulation, the wind shield opens to the maximum angle, and it is determined whether the wind shield is opened successfully. If the wind shield is not opened successfully, the wind shield indicator light is controlled to alarm; if the wind shield is opened successfully, the first control module monitors and adjusts the fan speed. If the baseboard management controller issues a control instruction, it is determined whether the baseboard management controller is disconnected. If so, the first control module monitors and adjusts the fan speed. If not, the fan is controlled to a fixed speed (a fixed speed corresponding to the control instruction), and the opening and closing angle of the wind shield is adjusted (according to the control instruction). When the power is turned off, the wind shield is controlled to close and the fan stops, and the process ends.

[0139] Furthermore, a direction sensor (such as a Hall effect sensor or photoelectric sensor) can be installed in the fan drive circuit to monitor the fan's rotation direction in real time. The sensor must be able to distinguish between clockwise (normal) and counterclockwise (reverse) fan rotation. During system startup, the direction sensor collects real-time fan rotation direction data and transmits this data to the control system (such as the BMC or the first control module). If abnormal fan rotation direction (i.e., reverse rotation) is detected, the control signal (such as the PWM (Pulse Width Modulation) signal) in the fan drive circuit is adjusted using a reversal repair algorithm to restore the fan to the correct rotation direction. Alternatively, if the reversed fan current direction is detected to be opposite to the normal direction, the power supply circuit can be instantly shut off to protect the fan motor from damage. In addition, a visual monitoring interface is provided to display the fan's real-time status, including speed, rotation direction, temperature, and possible abnormalities. Users can use this interface to monitor the fan's operating status and make manual adjustments as needed.

[0140] For further introduction to the temperature adjustment method, please refer to the above embodiments, and this application will not go into details here.

[0141] Fourthly, Figure 5 As shown, the present application provides a temperature adjustment device, including: a memory 51 for storing a computer program; and a processor 52 for implementing the steps of the temperature adjustment method described above when executing the computer program. For other descriptions of the temperature adjustment device, please refer to the above embodiments, and this application will not repeat them here.

[0142] It should also be noted that, in this specification, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.
