Description

Technical Field

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

[0002] As a key component, the power supply of a server is mainly responsible for providing stable power support for various components inside the server (such as the motherboard, central processing unit, memory, etc.). To ensure effective heat dissipation during the operation of the server, a fan is usually installed inside the server to dissipate heat for various components inside the server. At the same time, a separate fan is also provided inside the power supply module to dissipate heat for each module inside the power supply (such as the input module, output module, control circuit, etc.). However, when there are two fans inside the server, the fan inside the power supply is easily interfered by the airflow of the server fan, resulting in the risk of fan reverse rotation. Fan reverse rotation may increase the friction between the fan blades and the motor shaft, and then cause damage to the fan. Once the fan is damaged, the heat dissipation capacity of the power supply module will be greatly reduced, which may lead to overheating of the power supply, and then cause damage to the power supply module or server downtime.

[0003] To solve this problem, the current solution is to disassemble the power supply module and replace the damaged fan inside, but this not only increases the maintenance cost, 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, a server, a temperature adjustment method and a device, which can achieve efficient heat dissipation of the power supply and the motherboard with only one fan, avoiding the risk of air flow interference and reverse caused by the setting of additional fans; when any functional module is abnormal, the wind deflector closes to block the interference of external air flow on the fan. At the same time, the fan stops rotating, thereby avoiding frictional damage caused by the reverse rotation of the fan, reducing the maintenance cost, and improving the reliability and heat dissipation efficiency of the system.

[0056] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0057] In a first aspect, as Figure 1 shown, the present application provides a power supply applied to a server. The server further includes a motherboard, a fan 11, and a wind deflector 12. The power supply includes at least two functional modules; the fan 11 is disposed at a first end of the air duct, the wind deflector 12 is disposed at a second end of the air duct, the fan 11 is adjacent to the motherboard in the server, the overall input ends of the at least two functional modules are connected to a power supply, the overall output ends of the at least two functional modules are respectively connected to the power supply end of the motherboard and the power supply end of the fan 11, and the 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 the at least two functional modules to provide power for the motherboard; the wind deflector 12 is used to adjust its opening and closing angle according to a first preset instruction when the states of all the functional modules are normal, and close when the state of any one of the functional modules is abnormal; the fan 11 is used to adjust its rotation speed according to a second preset instruction to dissipate heat from the motherboard and the power supply when the states of all the functional modules are normal, and stop rotating when the state of any one of the functional modules is abnormal.

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

[0059] The overall input ends of all functional modules are connected to the power supply of the server. The input power supply may be an AC power supply from an external socket, which enters the power system through a power adapter for conversion. The overall output ends of all functional modules are respectively connected to the power supply end of the motherboard and the power supply end of the fan 11. The motherboard requires multiple different voltages (such as 3.3V, 5V, 12V, 54V, etc.) to drive different components, and the fan 11 requires a stable power supply to control its rotation speed. The functional modules in the power system output different voltages to meet these requirements.

[0060] The air duct design in the server is for efficient heat dissipation. The fan 11 is set at the first end of the air duct, usually close to the power supply and the motherboard, so as to dissipate heat effectively when the server is working. The fan 11 takes away heat through air flow to ensure that the motherboard and the power supply do not malfunction due to excessive temperature during operation.

[0061] Setting the fan 11 in a position closely adjacent to the motherboard can ensure that the heat generated by the motherboard during operation, especially under high load conditions, can be quickly taken away by the fan 11. The rotation speed of the fan 11 can be automatically adjusted according to the temperature of the motherboard or other system parameters.

[0062] The wind deflector 12 is located at the second end of the air duct, and its function is to adjust the direction and volume of the air flow. When the functional modules are working properly, the wind deflector 12 adjusts its opening and closing angle according to the first preset instruction to optimize the air flow distribution, ensuring that the air can flow smoothly through the entire system to achieve efficient heat dissipation.

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

[0064] Each functional module can judge whether it is in a normal working state by monitoring current, voltage or other parameters. If an abnormality occurs in a certain functional module, corresponding safety measures are taken immediately. At this time, the wind deflector 12 will close to prevent external air flow from interfering with the fan 11, and at the same time the fan 11 will stop rotating. This can effectively avoid frictional damage caused by the wrong rotation direction or reverse rotation of the fan 11, thereby reducing maintenance costs.

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

[0066] The fan 11 not only plays a role in heat dissipation, but is also closely related to the operating state of the server. Its rotation speed is intelligently adjusted according to the temperature conditions of the power supply and the motherboard, as well as the operating state of the functional modules. When all the functional modules are working properly, the fan 11 adjusts its own rotation speed according to the second preset instruction to meet the heat dissipation requirements of the system. For example, when the loads of the motherboard and the power supply are high, the rotation speed of the fan 11 will increase to enhance the air flow to take away more heat. On the contrary, when the load is low, the rotation speed of the fan 11 will slow down, thus reducing noise and saving energy consumption. If any functional module malfunctions, the fan 11 will stop rotating. This design effectively avoids the damage to the hardware caused by the reverse rotation of the fan 11. In particular, the reverse rotation of the fan 11 in the power supply system may cause unstable current, which may damage the fan 11 itself or cause other electrical faults.

[0067] In this embodiment, through intelligent air duct management, fault detection and response mechanisms, efficient heat dissipation and high-security operation are achieved. By intelligently adjusting the rotation speed of the fan 11 and the angle of the wind deflector 12, not only the heat dissipation effect is optimized, but also the redundancy capacity of the system is improved. Most importantly, in case of an abnormality, the air flow of the abnormal functional module can be automatically cut off, avoiding hardware damage caused by the reverse rotation of the fan 11, greatly reducing the maintenance cost, and improving the reliability and heat dissipation efficiency of the entire system.

[0068] As Figure 1 and Figure 2 shown, as an alternative 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, and the output end of the input module 13 is respectively connected to the input end of the power conversion module and the power supply end of the wind deflector 12, and the output end of the output module 15 is respectively connected to the power supply end of the fan 11 and the power supply end of the motherboard; the input module 13 is used to filter the power supply and provide power for the wind deflector 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 supply power for the fan 11 and the motherboard.

[0069] In this embodiment, the power supply system works together through three functional modules - the input module 13, the power conversion module, and the output module 15 to achieve stable power supply and efficient heat dissipation management.

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

[0071] The filtered power supply enters the power conversion module. The main task of the power conversion module is to convert the input power signal (usually alternating current) into a DC power supply suitable for internal use in the system (such as 12V, 54V, in Figure 1 is 12Vdc / 54Vdc). The power conversion module usually includes multiple functional components such as rectification, filtering, and voltage regulation, which can convert alternating current into multiple stable DC voltages to meet the different power supply requirements of the motherboard and the fan 11. The conversion of the power supply by the power conversion module is not only to provide a stable DC voltage but also to dynamically adjust the output voltage and current according to the changes in the system load and power demand to maintain the efficient operation of the entire system.

[0072] The DC power supply is distributed through the output module 15. The output module 15 is responsible for further regulating the DC power supply from the power conversion module and outputting it to the fan 11 and the motherboard respectively. The power supply requirement of the fan 11 is mainly to drive the fan 11 motor to adjust the rotation speed of the fan 11 to help the system dissipate heat; while the motherboard requires multiple different voltages to drive each core component, such as the processor, memory, etc. The output module 15 ensures that both the fan 11 and the motherboard receive a stable and appropriate power supply according to their actual power demands, thus ensuring the normal operation of the motherboard and the fan 11.

[0073] Overall, this embodiment ensures the stability and adaptability of the power supply. The input module 13 filters the power supply, the power conversion module converts it into the required DC power supply, and finally the output module 15 accurately distributes the power to ensure that the fan 11 and the motherboard receive sufficient power. The system also optimizes the air flow and heat dissipation effect through the power supply of the windshield 12 and its adjustment function, providing more efficient and stable power support for the server operation.

[0074] Such as Figure 2As shown, as an optional embodiment, it further includes: a first control module 18, whose output end is connected to the communication end of the main board through an 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 the communication data between the first control module 18 and the main board, and transfer the sampling information of the fan 11 to the main board; the first control module 18 is used to adjust the rotation speed of the fan 11 and the opening and closing angle of the wind deflector 12 according to the temperature acquisition parameters when the main board does not issue a control instruction, and adjust the rotation speed of the fan 11 and the opening and closing angle of the wind deflector 12 according to the control instruction when the main board 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 wind deflector 12 and optimize the heat dissipation management of the system. The working principle of the entire power system can be divided into two main stages: main board control and automatic adjustment.

[0076] In the automatic adjustment stage, that is, when the first control module 18 does not receive a clear control instruction issued by the main board, the first control module 18 will automatically adjust the rotation speed of the fan 11 and the opening and closing angle of the wind deflector 12 according to the temperature acquisition parameters (such as the temperature data of each component inside the server). The temperature sensor continuously monitors the temperature conditions of the main board, the fan 11, and other key components, and feeds back this data to the first control module 18. By analyzing these temperature data, the first control module 18 can judge the current heat dissipation requirements of the system and adjust the rotation speed of the fan 11 and the angle of the wind deflector 12 according to the set logic. For example, when the temperature is relatively high, the system will automatically increase the rotation speed of the fan 11 and adjust the opening and closing angle of the wind deflector 12 to ensure smooth air circulation and enhance the heat dissipation effect; when the temperature is relatively low, the rotation speed of the fan 11 will decrease, and the wind deflector 12 may be adjusted to a smaller opening and closing angle to reduce energy consumption and noise.

[0077] In the main board control stage, that is, when the main board issues a control instruction to the first control module 18, the first control module 18 will adjust the rotation speed of the fan 11 and the opening and closing angle of the wind deflector 12 according to these instructions. These instructions are usually the result of a comprehensive judgment based on multiple factors such as system load, ambient temperature, and heat dissipation requirements. The main board can finely adjust the fan 11 and the wind deflector 12 through control instructions to achieve more efficient heat dissipation, reduce noise, or improve system stability. For example, when the main board detects that the processor load is too high or the device temperature is too high, it may issue an instruction to require the fan 11 to accelerate and the wind deflector 12 to open at a larger angle to improve air fluidity.

[0078] In addition, the first control module 18 transmits the sampling information collected by the temperature sensor (such as the rotation speed of the fan 11, the temperature of the air duct, the current and voltage of the main board, etc.) to the main board through the output module 15, and feeds back the working state of the fan 11. In this way, the main board can make dynamic decisions based on real-time data to further optimize the operating state of the power supply system. Through this data interaction mechanism, the heat dissipation strategy can be adjusted more precisely to ensure that key components such as the main board and the power supply can maintain the best working temperature under any circumstances.

[0079] In summary, when there is no control instruction, the first control module 18 intelligently adjusts the working states of the fan 11 and the wind deflector 12 based on the automatically collected temperature parameters; when receiving a control instruction from the main board, it precisely adjusts these components according to the instruction to ensure the heat dissipation and stability of the system. Through real-time data transmission and a flexible control mechanism, the entire system can dynamically adapt according to the actual load and environmental conditions, thereby improving the efficiency, reliability, and energy utilization rate of the system.

[0080] As an optional embodiment, when the main board does not issue a control instruction, the rotation speed of the fan 11 and the opening / closing angle of the wind deflector 12 are regulated according to the temperature acquisition parameters, including: when the main board does not issue a control instruction and the power is on, the wind deflector 12 is controlled to open, and the opening angle of the wind deflector 12 is adjusted to a preset angle, and the rotation speed of the fan 11 is adjusted according to the temperature acquisition parameters.

[0081] In this embodiment, when the main board (especially the BMC (Baseboard Management Controller)) does not issue a control instruction, the normal operation and heat dissipation efficiency of the server are maintained through automatic adjustment. The system automatically regulates the rotation speed of the fan 11 and the opening / closing angle of the wind deflector 12 according to the real-time temperature acquisition parameters to ensure the best heat dissipation and energy efficiency management of the server under different working states.

[0082] When the system is powered on and the main board does not issue any control instruction, automatic adjustment is performed according to the default temperature acquisition parameters. First, the control system ensures that the wind deflector 12 is opened and adjusted to a preset opening / closing angle. The opening angle of the wind deflector 12 is usually set to an angle that can maximize the air flow to help the system dissipate heat quickly. After the wind deflector 12 is opened, the rotation speed of the fan 11 is automatically adjusted according to the data collected by the temperature sensor. If the temperature inside the server is high, the rotation speed of the fan 11 will be increased to enhance heat dissipation; if the temperature is low, the rotation speed of the fan 11 will be appropriately reduced to reduce energy consumption and noise.

[0083] As an alternative embodiment, after controlling the wind deflector 12 to open and adjusting the opening angle of the wind deflector 12 to a preset angle, it further includes: obtaining the current opening angle of the wind deflector 12 and determining whether the current opening angle is the preset angle; if so, entering the step of adjusting the rotation speed of the fan 11 according to the temperature acquisition parameter, otherwise controlling the prompting device of the wind deflector 12 to emit a preset prompt message.

[0084] After the wind deflector 12 is opened and adjusted to the preset angle, further check whether the current opening and closing angle of the wind deflector 12 meets the preset standard. If the current angle is consistent with the preset angle, the next step will be continued, that is, adjusting the rotation speed of the fan 11 according to the temperature acquisition data to ensure the optimization of heat dissipation efficiency and energy utilization. If the current angle does not reach the preset angle, the system will control the prompting device of the wind deflector 12 (the prompting device of the wind deflector 12 can be an indicator light) to emit a preset prompt message, reminding the user or the operation and maintenance personnel to perform necessary inspections or adjustments. This mechanism ensures that the system can maintain the best heat dissipation state under the optimized air flow control of the air duct.

[0085] As an alternative embodiment, when the main board does not issue a control instruction, the rotation speed of the fan 11 and the opening and closing angle of the wind deflector 12 are regulated according to the temperature acquisition parameter, including: when the main board does not issue a control instruction and the power is down, controlling the wind deflector 12 to close and controlling the fan 11 to stop rotating within a preset time period.

[0086] When the power is down, controlling the actions of the wind deflector 12 and the fan 11 is mainly to prevent the fan 11 from reversing (rotating in the reverse direction) due to the influence of external air flow after the system is powered off. When the power is down, the system first closes the wind deflector 12 to cut off the air flow passage. The purpose of closing the wind deflector 12 is to prevent external air flow from entering the air duct, which can effectively prevent the external air flow from having an impact on the reverse rotation of the fan 11. Closing the wind deflector 12 not only reduces the air flow interference but also plays a role in isolating the influence of external environmental changes on the fan 11. In addition to closing the wind deflector 12, the system also controls the fan 11 to stop rotating within a preset time period. The key role of this strategy is to ensure that the fan 11 no longer rotates when the power is off. Even if there is external air flow, it will not generate a driving force for the reverse rotation of the fan 11. By stopping the fan 11 from rotating, the system effectively avoids the reverse rotation of the fan 11 due to external factors, thus eliminating the risk brought by reverse rotation.

[0087] It can be seen that in this embodiment, when the power is down, by closing the wind deflector 12 and stopping the rotation of the fan 11, it is ensured that the fan 11 does not reverse due to external air flow without power drive. This control strategy can prevent potential damage caused by the reverse rotation of the fan 11, extend the service life of the equipment, and reduce the risk of poor heat dissipation or hardware damage caused by reverse rotation.

[0088] As an alternative embodiment, the first control module 18 is further configured to monitor the signal connectivity between the main board and itself. When the main board is connected to itself and no control instruction is issued, or when the main board is disconnected from itself, it enters the step of regulating the rotation speed of the fan 11 and the opening / closing angle of the wind deflector 12 according to the temperature acquisition parameters.

[0089] In this embodiment, the first control module 18 is not only responsible for adjusting the rotation speed of the fan 11 and the opening / closing angle of the wind deflector 12 according to the temperature acquisition parameters, but also adds a monitoring function for the signal connectivity between the main board (especially the BMC on the main board) and the first control module 18. This monitoring mechanism ensures that the system can make appropriate responses under different working conditions to ensure the normal heat dissipation and efficient operation of the server.

[0090] Specifically, the first control module 18 continuously monitors the signal connection status between the main board and itself. This monitoring usually focuses on key communication signals such as data transmission and control instruction transfer between the main board and the first control module 18. If the signal connection between the main board and the first control module 18 is normal (i.e., the main board is connected to the control module and no control instruction is issued), it enters the mode of automatically regulating the rotation speed of the fan 11 and the opening / closing angle of the wind deflector 12 according to the temperature acquisition parameters; if the signal connection is disconnected, or in the case of not receiving a control instruction from the main board, the first control module 18 will also start the same automatic adjustment mechanism.

[0091] Under normal circumstances, the BMC or the main board may issue a control instruction to guide the first control module 18 on how to adjust the rotation speed of the fan 11 and the angle of the wind deflector 12 when the preset control requirements are met. Usually, the BMC will determine the speed of the fan 11 and the opening / closing degree of the air duct according to the internal workload, data of the temperature sensor or other operating states. However, if for some reason the main board does not issue an instruction (such as the BMC not working, communication failure or other problems), or the connection between the main board and the first control module 18 is disconnected, it still needs to continue running and maintain appropriate heat dissipation performance.

[0092] Once it is detected that the signal connection between the main board and the first control module 18 is disconnected or no control instruction is issued, the first control module 18 will automatically adjust the rotation speed of the fan 11 and the angle of the wind deflector 12 according to the real-time temperature acquisition parameters. For example, when the temperature of the server rises, the first control module 18 will automatically increase the rotation speed of the fan 11 to enhance heat dissipation and adjust the opening / closing angle of the wind deflector 12 to optimize the air flow; when the temperature is low, it will reduce the rotation speed of the fan 11 and adjust the opening / closing angle of the wind deflector 12 to reduce energy consumption and noise.

[0093] In this embodiment, the core objective is to ensure that adjustments can be made according to the actual temperature requirements under any circumstances, without relying on the control instructions of the motherboard. This self-regulating mechanism is particularly important in the event of motherboard failure, signal loss, or faults, ensuring that the server can still maintain a normal operating state when external control instructions cannot be obtained, and avoiding overheating or other hardware damage caused by poor heat dissipation.

[0094] In summary, in this embodiment, by introducing the monitoring of the signal connectivity between the motherboard and the first control module 18, the system can automatically adjust the rotation speed of the fan 11 and the opening / closing angle of the wind deflector 12 according to the temperature acquisition parameters when the motherboard does not issue control instructions (whether due to signal disconnection or other reasons). This mechanism enables the system to maintain heat dissipation performance in the absence of motherboard control instructions, ensuring the long-term stable operation of the server, reducing the risk of heat dissipation out of control caused by motherboard problems, and enhancing the fault tolerance and reliability of the system.

[0095] As Figure 2 shown, as an optional embodiment, the output module 15 includes: a collection circuit 21, whose input end is connected to the sampling end of the fan 11, for sampling the status information and rotation 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 collection circuit 21 and the output end of the first control module 18, and whose second end is connected to the motherboard, for transmitting the communication data between the first control module 18 and the motherboard, and for transmitting the sampling information of the fan 11 to the motherboard; 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 supply end of the fan 11 and the power supply end of the motherboard, for outputting a DC power supply to supply power to the fan 11 and the motherboard.

[0096] In this embodiment, the functions of the output module 15 mainly include three key parts: the collection circuit 21, the signal circuit 23, and the power supply circuit 22. Each part works in coordination to ensure that the system can stably transmit the necessary communication data, provide continuous power supply for the fan 11 and the motherboard, and monitor the working state and rotation speed of the fan 11.

[0097] The function of the collection circuit 21 is to monitor the status information of the fan 11 in real time, including the rotation speed and operating conditions of the fan 11. Through the collection circuit 21, the system can obtain the operation data of the fan 11, such as the current rotation speed, working load, etc., so as to ensure the efficiency and stability of the fan 11 under different working conditions. These sampling information are crucial for adjusting the operation of the fan 11, especially when the temperature changes or the load fluctuates.

[0098] The signal circuit 23 is responsible for processing and transmitting communication data. It not only transmits the status information of the fan 11 obtained by the acquisition circuit 21 to the main board, but also realizes the bidirectional data exchange between the first control module 18 and the main board. Through the signal circuit 23, the main board can obtain the working status of the fan 11, so as to make a decision on whether to adjust the rotation speed of the fan 11. At the same time, the signal circuit 23 can also transmit the control signal of the first control module 18 to the main board to realize the coordinated control of the main board and the fan 11.

[0099] The power supply circuit 22 ensures the power supply of the entire system. Through the power supply circuit 22, the DC power supply is output from the power conversion module and is effectively distributed to the fan 11 and the main board to ensure their continuous operation. The power supply circuit 22 can stably supply power according to the power consumption requirements of the fan 11 and the main board, ensuring the electrical stability and reliability of the system.

[0100] Overall, these three parts work together to ensure the orderly progress of the status monitoring, data transmission and power supply of the fan 11, guaranteeing the heat dissipation management and stable operation of the system. When the status of the fan 11 changes or the temperature changes, the output module 15 can provide real-time data feedback and adjust the rotation speed of the fan 11, thereby optimizing the heat dissipation effect of the system and adjusting the power distribution according to the requirements of the main board. This process enables the system to work efficiently and stably, reducing the risks brought by heat dissipation failure and overheating.

[0101] As Figure 1 shown, as an optional embodiment, the power conversion module includes: a power factor correction module 16, whose input end is connected to the output end of the input module 13, and is used 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 factor correction module 16, and is used 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 but is not limited to include two parts, namely the power factor correction module 16 and the DC conversion module 17, aiming to ensure that the input power supply can meet the requirements of the system for different voltage needs after being processed, while improving the power utilization efficiency.

[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 describing the efficiency of the power system, which measures the ratio between the actual power (useful work) and the apparent power (total work). In the power system, due to the non - linearity of the load, the power factor is often low, resulting in waste of electrical energy. The power correction module 16 adjusts the waveform of the input power supply, reduces the reactive power, and improves the power factor, so that the system can utilize electrical energy more efficiently. After power factor correction, the input power supply is converted into a relatively high - voltage DC power supply, that is, the first DC power supply ( Figure 1 which is 380Vdc - 420Vdc in

[0104] ). Its voltage is relatively high, providing suitable input conditions for subsequent voltage conversion. Figure 1 The DC conversion module 17 converts the first DC power supply after power correction into a second DC power supply with a lower voltage (

[0105] which is 12Vdc / 54Vdc in

[0106] ), meeting the requirements of the system for different voltage levels. Since the voltage of the first DC power supply is higher than that of the second DC power supply, the DC conversion module 17 usually adopts step - down conversion technology, such as a Buck converter, to reduce the voltage to the required value. This step - down process can not only achieve voltage adaptation but also effectively regulate the current, ensuring that the power supply provides a stable and reliable voltage output for the system. Figure 1 As an optional embodiment, as

[0107] shown, it further includes: a second control module 19, whose output terminal is connected to the parameter setting terminal 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.

[0108] The performance of the power correction module 16 is often affected by internal parameters (such as voltage, current regulation parameters, power factor regulation parameters, etc.). These parameters need to be adjusted in a timely manner according to different input power supply conditions and system requirements. The second control module 19 can dynamically adjust the internal settings of the power correction module 16 by receiving target parameters, ensuring that the system can maintain high efficiency and stability when operating in various environments. The target parameters can be adjusted according to changes in the load of the power supply, fluctuations in the input voltage, 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 update refers to updating the operation logic or functional modules of the power correction module 16 by transmitting new program codes or configuration files. This is usually carried out when the system needs to be upgraded, bugs need to be fixed, or new functions need to be introduced. Through firmware updates, the power management ability can be improved without replacing hardware, the efficiency of power factor correction can be increased, and the overall power consumption of the system can be optimized.

[0110] The second control module 19 enables the power correction module 16 to flexibly adapt to different working scenarios and requirements. For example, when the power input conditions change, the second control module 19 can update the settings of the power correction module 16 in real time according to the new target parameters, thus ensuring that the power supply system is always in the best operating state. This adaptability enables the power supply to operate stably in the face of various loads and input power fluctuations and maximizes the energy use efficiency.

[0111] Through regular parameter updates and firmware upgrades, the second control module 19 can ensure that the power correction module 16 always operates in an optimized state, avoiding performance degradation or failures caused by old firmware or inappropriate parameter settings. It is adjusted remotely or locally, improving the intelligent management ability of the power supply system, thereby enhancing the stability, reliability, and long-term use efficiency of the system.

[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 update and firmware update functions. This enables the power supply to be adjusted according to different input conditions, optimize power factor correction and power use efficiency, maintain the system running efficiently and stably, and improve the long-term performance of the system through firmware updates. This mechanism greatly enhances the adaptive ability and intelligent management ability of the power supply system, helps to extend the service life of the device, and improves the overall reliability of the system.

[0113] Such as Figure 1As shown, as an optional embodiment, it further 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, and is used to convert 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 function of the auxiliary power supply module 14 is to provide an additional power output, called the 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 main power conversion module. This design provides additional power support for the system, especially when the main power supply (i.e., the DC power supply output by the power conversion module) cannot meet the specific load requirements.

[0115] At the input end of the system, the input module 13 first filters the external power supply to effectively suppress the noise and fluctuations in the power supply. This step provides a stable power basis for subsequent power correction and power conversion. The input module 13 transfers 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 voltage of the DC power supply 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 specific modules with different voltage requirements in the system, such as sensors, control circuits or other small loads, without relying on the voltage of the main power supply.

[0116] The auxiliary DC power supply output by the auxiliary power supply module 14 is usually used to drive some system modules that do not match the main power supply voltage. By providing a voltage different from the main power supply, the auxiliary power supply module 14 can flexibly support devices with various voltage requirements. Especially when the voltage provided by the main power supply is not suitable for some special circuits or modules, the auxiliary power supply can solve this problem. 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), and the auxiliary power supply can provide this low-voltage support.

[0117] Since the auxiliary power supply module 14 can work 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 the reliability of the entire system. Especially when some key modules require a constant voltage supply, the auxiliary power supply can ensure that these modules always obtain stable power, avoiding voltage instability caused by main power supply fluctuations or load changes.

[0118] The output of the auxiliary power supply module 14 is transmitted to the output module 15 to provide the required voltage support for the output module 15. The output module 15 will transfer the power of the main power supply and the auxiliary power supply to the fan 11, the motherboard, and other modules that require power support according to the power demand, so as to ensure the stable operation of the entire system under the condition of multi-voltage demand.

[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, and the two control modules can be MCUs (Microcontroller Units).

[0120] In summary, the auxiliary power supply module 14 in this embodiment provides an independent and adjustable voltage output by converting the filtered power supply into an auxiliary DC power supply different from the main power supply, meeting the independent voltage requirements of specific loads in the system. This design enhances the flexibility and adaptability of the system, especially when it is necessary to supply power to multiple modules with different voltage requirements. At the same time, it can also share the burden of the main power supply, improving the stability and reliability of the system.

[0121] As Figure 1 shown, as an alternative 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 components of the power supply system are arranged on both sides of the air duct to optimize the heat dissipation effect and improve the overall efficiency of the system. Specifically, the power correction module 16 and the DC conversion module 17 are arranged on the first side of the air duct, while the input module 13, the auxiliary power supply module 14, and the output module 15 are arranged on the second side of the air duct. This arrangement method plays an important role in the heat dissipation performance, working stability, and power management of the power supply system.

[0123] The power correction module 16 and the DC conversion module 17 are mainly responsible for performing power factor correction and voltage conversion on the input power supply to ensure a stable and appropriate DC voltage for the power supply system. These modules usually generate a relatively high amount of heat. Therefore, they are arranged on the first side of the air duct, which helps to centrally process the generated heat and take away the heat through the air flow in the air duct. Arranging them on the first side of the air duct can ensure that this heat is quickly taken away by the air flow in the air duct, avoiding overheating from affecting the performance or lifespan of the modules.

[0124] The input module 13, the auxiliary power module 14, and the output module 15 are arranged on the second side of the air duct. The input module 13 is responsible for receiving and filtering the power supply from an external power source. The auxiliary power module 14 will provide an independent auxiliary voltage output, while the output module 15 is responsible for outputting the DC power supply to the fan 11, the motherboard, and other loads. The heat generated by these modules is usually relatively less, so they can be arranged on the second side of the air duct, separated from the high-power modules on the first side, thereby optimizing the air flow distribution and avoiding the mutual interference of heat between the modules.

[0125] In addition, this layout can also reduce the electromagnetic interference between different power modules inside the system because the positions of the power modules are more dispersed, which can achieve the optimal effect of air flow 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 deflector 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 deflector 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 the DC conversion module 17 on the first side of the air duct, and arranging the input module 13, the auxiliary power module 14, and the output module 15 on the second side of the air duct, the air flow and heat dissipation performance can be effectively optimized. This layout can not only ensure that the heat of the high-power modules is quickly removed, but also avoid the influence 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, including the power supply as described above, further including a fan and a wind deflector. The output terminals of the power supply are respectively connected to the power supply terminal of the fan and the power supply terminal of the motherboard. For other introductions of the server, please refer to the above embodiments, and the present application will not elaborate herein.

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

[0130] S11: Monitor the states of the various functional modules in the power supply and determine whether there are any functional modules with abnormal states.

[0131] In this step, the working states of each functional module in the power supply are tracked in real time through a series of sensors and monitoring modules. Each functional module (such as the input module, power correction module, DC conversion module, etc.) may have problems such as overheating, overload, abnormal voltage or other performance issues, and these abnormal conditions will affect the stability and efficiency of the system. By monitoring these functional modules, the system can detect abnormal states in a timely manner. Generally speaking, the monitoring module will judge the state by collecting key parameters such as the temperature, current, voltage, etc. of each functional module. When the parameters of a certain module are detected to deviate from the normal range, the system will determine that the functional module has an abnormality. During this process, the control system will analyze and judge whether the power supply system is in a normal working state based on the information provided by the sensors, and then decide whether to enter the subsequent regulation steps.

[0132] S12: When the states of all functional modules are normal, adjust the opening and closing angle of the wind deflector according to the first preset instruction, and adjust the rotation speed of the fan according to the second preset instruction to dissipate heat from the power supply and the main board.

[0133] When the system detects that all functional modules are in a normal working state, this step is activated. At this time, adjust the opening and closing angle of the wind deflector according to the first preset instruction. The function of the wind deflector is to guide the air flow and optimize the air flow path, thereby improving the heat dissipation efficiency. The first preset instruction is usually an optimal angle automatically calculated according to the system working state (such as load, ambient temperature, etc.). Adjusting the angle of the wind deflector can make the air flow better flow to the power supply and the main board to ensure that these key components are properly cooled.

[0134] At the same time, the second preset instruction will be used to adjust the rotation speed of the fan. The rotation speed control of the fan directly affects the intensity of the air flow and the heat dissipation efficiency. When the functional module is in a normal state, the rotation speed of the fan may be adjusted according to the temperature acquisition information of the main board or the ambient temperature to ensure that the power supply and the main board are always in the optimal temperature range. The goal of this process is to maintain the temperature balance of the system through intelligent temperature control, avoid overheating, and thus ensure the safe operation of the power supply and the main board.

[0135] S13: When the state of any functional module is abnormal, control the wind deflector to close and the fan to stop rotating according to the second preset instruction.

[0136] When the system detects an abnormal status of a certain functional module, this step will be immediately initiated. This is a protective measure aimed at preventing further damage or system instability caused by faults or anomalies. In this case, the windshield will be closed according to the second preset instruction. The purpose of closing the windshield is to cut off the interference of external airflows, prevent the functional module in the abnormal state from being further affected by external environmental factors, or prevent additional heat accumulation caused by uneven airflows. In addition, the fan will stop rotating to avoid problems such as fan reverse rotation or friction, thereby protecting the fan from damage. The fan stopping rotation helps to avoid airflow disorders in the abnormal state, which may cause additional thermal effects or electrical damage to other modules. Through these control measures, the system can ensure that even in the event of an anomaly, the power system can effectively protect its own safety while avoiding damage to other hardware components.

[0137] In summary, these steps form a closed-loop control system based on anomaly detection and temperature regulation. In the normal operating state of the system, effective heat dissipation is ensured by dynamically adjusting the settings of the windshield and the fan; while when an abnormal situation occurs in the functional module, by closing the windshield and stopping the operation of the fan, more serious problems caused by the abnormal situation are avoided, protecting system stability and hardware safety. This intelligent temperature adjustment method effectively improves the heat dissipation efficiency of the system and enhances the system's ability to respond to sudden failures.

[0138] A specific implementation example of the temperature adjustment method is as Figure 4 shown. At the beginning, when the power is turned on, the fan resumes automatic speed regulation, and the windshield opens to the maximum angle. It is judged whether the windshield is successfully opened. If the windshield is not successfully opened, the windshield indicator light is controlled to give an alarm; if the windshield is successfully opened, the first control module monitors and adjusts the fan speed. If the baseboard management controller issues a control instruction, it is judged 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 rotate at a fixed speed (the fixed speed corresponding to the control instruction), and the opening and closing angle of the windshield is adjusted (according to the control instruction). When the power is turned off, the windshield is controlled to close and the fan stops rotating, and the process ends.

[0139] Furthermore, a direction sensor (such as a Hall effect sensor, a photoelectric sensor, etc.) can be installed in the fan drive circuit to monitor the rotation direction of the fan in real time (the sensor needs to be able to distinguish between the clockwise (normal rotation direction) and counterclockwise (reverse rotation direction) rotations of the fan). When the system starts, the direction sensor will collect the rotation direction data of the fan in real time and transmit this data to the control system (such as BMC or the first control module). If it is detected that the rotation direction of the fan is abnormal (i.e., reverse rotation occurs), the control signal (such as a PWM (Pulse Width Modulation) signal) in the fan drive circuit is adjusted through a reverse rotation repair algorithm to make the fan return to the correct rotation direction. Or, if it is detected that the current direction of the reverse rotation fan is opposite to the normal situation, the power supply circuit can be instantaneously cut off to protect the fan motor from being damaged. In addition, a visual monitoring interface can also be provided to display the real-time status of the fan, including the rotation speed, rotation direction, temperature, and possible abnormal conditions. Users can monitor the operating status of the fan through this interface and make manual adjustments as needed.

[0140] For other introductions to the temperature adjustment method, please refer to the above embodiments, and the present application will not elaborate here.

[0141] Fourthly, as Figure 5 shown, the present application provides a temperature adjustment device, including: a memory 51 for storing a computer program; a processor 52 for implementing the steps of the temperature adjustment method as described above when executing the computer program.
