Description

Technical Field

[0001] The present invention relates to the field of server power supply, and particularly to a server power supply system and a server. Background Art

[0002] With the rapid development of artificial intelligence technology, especially in the fields of natural language processing (NLP), computer vision (CV), and automatic speech recognition (ASR), the demand for computing power has increased sharply, driving the widespread application of high-performance servers. However, the power consumption of these servers is extremely high, and the computing power density generally reaches more than 50 kW per computing cabinet, posing stringent requirements on the power supply system. At the same time, a series of environmental protection concepts have been put forward, requiring high-energy-consuming data centers to improve the power usage efficiency and reduce the power supply usage efficiency.

[0003] In the traditional power supply architecture, there are inherent energy losses due to its AC-based transmission method. Specifically, AC will generate heat losses due to resistance, electromagnetic induction, and capacitance effects during long-distance transmission, and multiple voltage conversions and transformations are required to adapt to the needs of different devices, further increasing the energy losses. Especially in high-power density scenarios, these losses are more significant. Therefore, the potential of the traditional power supply architecture to improve power transmission efficiency has approached its limit and it is difficult to meet the demand for efficient power supply of modern high-computing-power and high-energy-consuming devices.

[0054] The core of the present invention is to provide a server power supply system and a server, which improve the power transmission efficiency, reduce the energy loss, and meet the requirements of modern high-computing-power and high-energy-consumption servers for efficient power supply.

[0055] 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.

[0056] In a first aspect, as Figure 1 shown, the present application provides a server power supply system applied to a server, including: a power conversion module 11, whose input end is connected to a power supply, and whose output end is connected to a busbar 12. The power conversion module 11 is configured to convert the power output by the power supply into high-voltage direct current with a voltage higher than a preset voltage; a busbar 12, whose output end is connected to a power distribution board 13 of the server. The busbar 12 is configured to transmit the high-voltage direct current to the power distribution board 13; a power distribution board 13, whose output end is connected to a load node of the server. The power distribution board 13 is configured to convert the voltage of the high-voltage direct current into the required voltage of the load node to supply power to the load node.

[0057] In a traditional alternating current power supply architecture, inevitable losses such as resistance, electromagnetic induction, and capacitance effects will be encountered during long-distance power transmission, and energy will be gradually consumed during multiple voltage conversion processes, making it difficult for the energy efficiency of the traditional architecture to meet the requirements in high-computing-power and high-density scenarios.

[0058] The server power supply system of the present application aims to solve the requirements of high-power and high-energy-consumption servers for efficient power supply, improve the power transmission efficiency, and reduce the energy loss in the traditional alternating current power supply system. The present application optimizes the power supply efficiency by adopting high-voltage direct current power transmission and reducing multiple conversion links.

[0059] First, the power conversion module 11 converts the alternating current from the power supply into high-voltage direct current. Different from alternating current, direct current is hardly affected by electromagnetic induction and capacitance effects during long-distance transmission, so it can effectively avoid the additional energy loss caused by these factors. At the same time, by increasing the voltage to high-voltage direct current above the preset voltage, the current can be further reduced, thereby reducing the loss generated by the current.

[0060] High-voltage direct current is transmitted through the busbar copper strip 12. As a transmission medium, the busbar copper strip 12 has a low resistance and a high current-carrying capacity, which ensures that the power loss is minimized during transmission. Due to the excellent electrical conductivity of copper, it can withstand a large current while avoiding the extra heat generated by the current flowing through high-resistance materials in conventional power supply methods.

[0061] Next, the high-voltage direct current is sent to the power distribution board 13 of the server. The distribution board directly converts the high-voltage direct current into the low-voltage direct current required by the server load. Since the high-voltage direct current power supply is directly supplied to the power distribution board 13, the steps of multi-stage voltage conversion are omitted, which not only improves the overall efficiency of the system but also avoids the energy loss generated by multiple conversions.

[0062] Among them, the voltage range of the high-voltage direct current can usually be selected between 300V and 1000V, such as intermediate voltage values like 380V. Selecting this voltage range as the transmission voltage of the high-voltage direct current can ensure a lower current while reducing the energy loss caused by resistance during transmission. Compared with low-voltage direct current or alternating current, a higher voltage can effectively reduce the current intensity, and the reduction of the current means that the heat loss caused by resistance during transmission also decreases. This design not only improves the power transmission efficiency but also effectively reduces the operating temperature of the lines and equipment, extends the service life of the system, and reduces the burden on the environment caused by energy waste. Therefore, choosing the high-voltage direct current between 300V and 1000V as the transmission voltage not only achieves efficient and low-loss power transmission technically but also meets the high requirements of modern high-computing-power devices for power supply. It overcomes the limitation of the power transmission distance under the traditional power supply architecture and realizes the "decoupling" of power supply and computing from the power supply architecture.

[0063] In summary, in the entire power supply system, the efficient transmission and direct conversion of direct current greatly reduce the energy waste caused by various losses in alternating current transmission. By reducing intermediate links, especially avoiding the complex process of multiple voltage conversions and adaptations required to meet the needs of different devices in the traditional architecture, this design not only improves the power transmission efficiency technically but also meets the current requirements for energy efficiency and carbon emission control, and adapts to the urgent need for green and energy-saving power supply in large-scale data centers and high-performance servers. Therefore, the server power supply system of this application can not only significantly improve the power transmission efficiency, meet the power requirements of modern high-computing-power and high-energy-consuming servers, but also help reduce the negative impact on the environment.

[0064] Such as Figure 2As shown, as an alternative embodiment, the server further includes a server cabinet; the power conversion module 11 is disposed in a first preset area inside the server cabinet, the power distribution board 13 is disposed in a second preset area inside the server cabinet, the load nodes are disposed in a third preset area inside the server cabinet, the busbar copper row 12 is disposed on the back of the server cabinet, and the output end of the power conversion module 11 is connected to the busbar copper row 12 through a cable.

[0065] In this embodiment, the design of the server further optimizes the layout of power management and computing resources by setting multiple preset areas inside the server cabinet. The power conversion module 11 is disposed in the first preset area inside the server cabinet, which is specifically used for processing the input and conversion tasks of external power. The power conversion module 11 converts the external power supply into the required high-voltage direct current to ensure that the server can obtain a stable power supply. The power distribution board 13 is located in the second preset area inside the server cabinet and is responsible for converting the input high-voltage direct current into voltages suitable for the needs of different load nodes to ensure that each load node can obtain accurate power supply. The load nodes are disposed in the third preset area inside the server cabinet, and these nodes may be different computing units, such as central processing units, graphics processing units, etc., which respectively require power supplies with different voltages and currents. The busbar copper row 12 is disposed on the back of the server cabinet and serves as a medium for power transmission, transmitting the output power of the power conversion module 11 to the power distribution board 13 and finally providing stable power for each load node.

[0066] This embodiment integrates all the modules in the server into an overall server cabinet, enabling clear division of functions in each area, improving the efficiency and safety of power transmission, and facilitating daily maintenance and management.

[0067] As Figure 3 shown, as an alternative embodiment, the server further includes a power cabinet and a computing cabinet; the power conversion module 11 is disposed inside the power cabinet, the power distribution board 13 and the load nodes are disposed inside the computing cabinet, and the busbar copper row 12 is disposed on the back of the computing cabinet; the output end of the power conversion module 11 is connected to the busbar copper row 12 through a cable (i.e., Figure 3 the high-voltage copper cable in

[0068] In this embodiment, the structural design of the server system adopts a separated layout to optimize power distribution and improve the overall system operation efficiency. The power cabinet and the computing cabinet are respectively designed as independent modules, and the power conversion module 11 is centrally disposed inside the power cabinet, mainly responsible for converting the external power supply into high-voltage direct current.

[0069] This modular design facilitates the management and maintenance of the power supply section and enables efficient operation during the power conversion process. The power distribution board 13 and the load nodes are located inside the computing cabinet, specifically providing appropriate power to each load node within the computing cabinet. The busbar copper row 12, as the medium for power transmission, is arranged at the back of the computing cabinet to optimize space utilization and enhance heat dissipation. The busbar copper row 12 is responsible for transmitting the high-voltage direct current output by the power conversion module 11 to the power distribution board 13 inside the computing cabinet, and the power distribution board 13 then distributes it to each load node.

[0070] Through this separation design, the power supply section and the computing section do not interfere with each other, effectively reducing the impact of power interference on the computing module, and at the same time achieving relatively flexible and efficient power transmission and management.

[0071] As Figure 4 shown, as an optional embodiment, the power conversion module 11 includes: a first power conversion sub-module 42, whose input end is connected to the power supply, and the first power conversion sub-module 42 is configured to convert the alternating current output by the power supply into intermediate direct current; a second power conversion sub-module 43, whose input end is connected to the output end of the first power conversion sub-module 42, and whose output end is connected to the busbar copper row 12, and the second power conversion sub-module 43 is configured to convert the intermediate direct current into high-voltage direct current with a voltage higher than the preset voltage.

[0072] In this embodiment (denoted as Embodiment 1 of the power conversion module 11), the design of the power conversion module 11 improves the energy efficiency of the system and reduces energy loss by converting the voltage in stages. First, the first power conversion sub-module 42 is responsible for converting the alternating current output by the power supply into intermediate direct current. Alternating current is not suitable for direct use in efficient power transmission due to its periodic fluctuations, so it must be converted. This first sub-module converts the alternating current into direct current through processes such as rectification and filtering, and provides intermediate direct current, which can be further increased in voltage in subsequent steps. The intermediate direct current, as a stable voltage source, has less fluctuation and interference and is suitable for subsequent high-voltage conversion.

[0073] Next, the second power conversion sub-module 43 takes over the intermediate direct current output by the first sub-module and converts it into high-voltage direct current. At this time, the key task of the second sub-module is to increase the voltage of the intermediate direct current to above the preset voltage through boost conversion, thereby forming high-voltage direct current suitable for long-distance transmission. High-voltage direct current has a smaller current compared to low-voltage direct current, so it can reduce the resistance loss during transmission and effectively reduce the heat generated by the current, which is particularly important for power systems in high power density scenarios.

[0074] This two-stage power conversion structure helps optimize the energy conversion process and avoid energy losses that may occur when directly converting alternating current to high-voltage direct current. In the first stage, through the conversion of intermediate direct current, a stable voltage basis suitable for further boosting is provided for the second stage, thus achieving efficient voltage conversion and energy transmission. This phased conversion method not only improves the efficiency of power transmission but also reduces heat generation and energy losses during the power conversion process, thereby enhancing the performance of the entire system.

[0075] As Figure 4 shown, as an optional embodiment, the power conversion module 11 further includes: a switching switch 41, whose input terminal is connected to the power supply, whose first output terminal is connected to the input terminal of the first power conversion sub-module 42, and whose second output terminal is connected to the input terminal of the second power conversion sub-module 43; the switching switch 41 is configured to conduct the first path or the second path according to the type of power supply output by the power supply at its input terminal; the types of power supply include direct current or alternating current; the first path is the path between the input terminal and the first output terminal of the switching switch 41, and the second path is the path between the input terminal and the second output terminal of the switching switch 41.

[0076] In this embodiment, through the introduction of the switching switch 41, the power conversion module 11 realizes the selection of different power conversion paths according to different types of power supplies, thereby improving the adaptability and flexibility of the system. The function of the switching switch 41 is to intelligently select different power conversion paths according to the type of power supply to ensure that the system can operate normally under different input conditions and achieve the optimal conversion efficiency.

[0077] Specifically, the switching switch 41 has two output terminals, which are respectively connected to the input terminals of the two power conversion sub-modules. According to the type of power supply at the input terminal, the switching switch 41 determines which path to conduct. When the type of power supply at the input terminal meets the working requirements of the first power conversion sub-module 42 (i.e., when the input is alternating current), the switching switch 41 conducts the first path, allowing the current of the power supply to enter the first power conversion sub-module 42 through this path for conversion. On the other hand, when the input power type is more suitable for the second power conversion sub-module 43 (i.e., when the input is direct current), the switching switch 41 switches to the second path and conducts the power through the second path to the second power conversion sub-module 43 for further voltage conversion.

[0078] Figure 4Among them, alternating current and direct current are switched through the switching switch 41. If alternating current is input, it will pass through the first power conversion sub-module 42 (such as AC / DC (alternating current / direct current)) to rectify and output an intermediate direct current voltage, and then pass through the second power conversion sub-module 43 (such as DC / DC (direct current / direct current)) to step down, isolate and regulate the voltage. Finally, after filtering by the filtering module, a regulated and isolated high-voltage direct current is output; if direct current is input, after being switched by the switching switch 41, the rectification link of the first power conversion sub-module 42 can be skipped, and the step-down and filtering modules of the second power conversion sub-module 43 in the case of alternating current can be reused, and finally a 380V direct current voltage is also output. The reuse of the modules reduces the volume of the power conversion module 11 and improves the power density.

[0079] This design enables the power conversion system to flexibly respond to different types of power supply inputs, such as alternating current or direct current with different specifications, ensuring that the power conversion module 11 can effectively provide the required voltage in different power supply environments. The intelligent switching of the switching switch 41 not only optimizes the energy efficiency of the system but also improves the applicability of the power module, and can ensure the stable supply of power under various power supply conditions. In addition, this switching mechanism avoids energy waste or system failures caused by mismatched power types, thereby enhancing the reliability and stability of the overall system.

[0080] As an alternative embodiment, the power conversion module 11 includes: a first power conversion sub-module 42, whose input end is connected to the first power supply, and whose output end is connected to the busbar 12. The first power conversion sub-module 42 is configured to convert the alternating current output by the first power supply into a high-voltage direct current with a voltage higher than a preset voltage; a second power conversion sub-module 43, whose input end is connected to the second power supply, and whose output end is connected to the busbar 12. The second power conversion sub-module 43 is configured to convert the direct current output by the second power supply into a high-voltage direct current with a voltage higher than a preset voltage.

[0081] In this embodiment (denoted as Embodiment 2 of the power conversion module 11), the power conversion module 11 is designed with two power input sources to meet the conversion requirements of different types of power supplies. First, the first power conversion sub-module 42 is responsible for converting the alternating current provided by the first power supply into a high-voltage direct current. Specifically, the first power conversion sub-module 42 receives the alternating current from the first power supply, converts it into direct current through processes such as rectification and filtering, and further boosts it to a high-voltage direct current above the preset voltage. This conversion method can reduce current losses in high-power transmission and improve the power transmission efficiency of the system. Especially in high-power density application scenarios, it can ensure the efficient supply of power.

[0082] Meanwhile, the second power conversion sub-module 43 receives direct current from the second power supply and converts it into high-voltage direct current with a voltage higher than the preset voltage. Different from the first power conversion sub-module 42, the second power conversion sub-module 43 starts directly from the DC power supply, avoiding the conversion process from alternating current to direct current, thereby reducing additional energy losses. This design also uses boost technology to raise the input direct current to the required high-voltage direct current for transmission to the busbar 12 in the system, achieving stable and efficient power supply.

[0083] As an alternative embodiment, the power conversion module 11 further includes: a switch 41, whose first input terminal is connected to the first power supply, whose second input terminal is connected to the second power supply, whose first output terminal is connected to the input terminal of the first power conversion sub-module 42, and whose second output terminal is connected to the input terminal of the second power conversion sub-module 43; the switch 41 is configured to conduct the first path or the second path according to the type of power supply output by the power supply at its input terminal; the first path is the path between the first input terminal and the first output terminal of the switch 41, and the second path is the path between the second input terminal and the second output terminal of the switch 41.

[0084] To further improve the flexibility and adaptability of the system, the power conversion module 11 also introduces a switch 41. The function of the switch 41 is to automatically select a suitable power conversion path according to the type of power supply. Specifically, when the first power supply is alternating current, the switch 41 will conduct the first path and transmit the alternating current to the first power conversion sub-module 42 for conversion; when the second power supply is direct current, the switch 41 will conduct the second path and transmit the direct current to the second power conversion sub-module 43 for processing. This design allows the system to dynamically select the most suitable conversion path according to the type of current power supply, ensuring that the system can efficiently utilize different types of power supplies while avoiding energy waste caused by mismatched power supply types.

[0085] Through such a design, the power conversion module 11 can not only adapt to different power input types but also flexibly switch the power conversion path according to the actual situation, thereby improving the overall efficiency and reliability of the system. This switching mechanism also ensures that the power conversion module 11 can operate stably in a variety of power environments while minimizing energy losses and system failures.

[0086] The main differences between the above-mentioned First Embodiment and Second Embodiment lie in the methods and steps of power conversion. In the First Embodiment, a phased power conversion process is adopted. First, the alternating current of the power supply is converted into intermediate direct current by the first power conversion sub-module 42, and then the intermediate direct current is boosted to high-voltage direct current by the second power conversion sub-module 43. In this process, the first power conversion sub-module 42 is responsible for rectifying the alternating current into direct current, providing a stable intermediate direct current power supply for subsequent boosting. In the First Embodiment, the switching switch 41 conducts the first path or the second path according to the type of the power supply at the input end. However, these two paths are respectively connected to the input ends of the first power conversion sub-module 42 and the second power conversion sub-module 43. And the first power conversion sub-module 42 is responsible for converting the alternating current into intermediate direct current, and the second power conversion sub-module 43 boosts the intermediate direct current to high-voltage direct current. Therefore, the main function of the switching switch 41 in the First Embodiment is to select the type of the input power supply (alternating current or direct current) and determine which conversion path the power enters, so as to ensure that the power system automatically adjusts the working mode according to the power supply type.

[0087] In contrast, in the Second Embodiment, the alternating current of the first power supply and the direct current of the second power supply are directly converted into high-voltage direct current respectively. The function of the switching switch 41 is to select different power supplies (the first power supply or the second power supply) and determine which power supply enters the corresponding power conversion sub-module. At this time, the first power conversion sub-module 42 directly converts the alternating current into high-voltage direct current, and the second power conversion sub-module 43 converts the direct current into high-voltage direct current. Therefore, the selection of the switching switch 41 directly affects the input of the power supply, and the type of power conversion (alternating current to direct current or direct current to high-voltage direct current) has been fixed inside the sub-module.

[0088] The connection method of the switching switch 41 in the First Embodiment has higher flexibility and adaptability because it can intelligently select the conversion path under the input of different power supply types, and at the same time reduce energy loss and improve conversion efficiency through phased power conversion (first converting the alternating current into intermediate direct current, and then boosting the intermediate direct current to high-voltage direct current).

[0089] In the Second Embodiment, the connection method of the switching switch 41 directly connects the first power supply and the second power supply to the corresponding power conversion sub-modules respectively without intermediate steps. In this way, the switching switch 41 only needs to select the input source according to the power supply type, avoiding the extra complexity in the multi-stage conversion process. Since each power conversion sub-module directly processes the power supply suitable for its input type (alternating current or direct current), it can reduce the processing delay of the system and improve the response speed, thus ensuring to quickly and stably provide the required high-voltage direct current under different power supply conditions.

[0090] Such as Figure 5 and Figure 6As shown, as an alternative embodiment, the power distribution board 13 includes: a first power adaptation module 51, whose input end is connected to the bus bar copper row 12, and whose output end is respectively connected to the input end of the power supply module and the power supply end of the first preset load node; the first preset load node is the remaining load nodes except the central processing unit node and / or the graphics processing unit node; the first power adaptation module 51 is configured to convert the voltage of the high-voltage direct current into a first adapted voltage to supply power to the power supply module and the first preset load node; the power supply module, whose output end is connected to the power supply end of the second preset load node, and the second preset load node includes the central processing unit node and / or the graphics processing unit node; the power supply module is configured to convert the first adapted voltage into a preset voltage to supply power to the second preset load node.

[0091] In this embodiment, the core function of the power distribution board 13 is to achieve precise power distribution and conversion through the power adaptation module and the power supply module according to the different requirements of the load nodes. First, the power adaptation module converts the high-voltage direct current from the bus bar copper row 12 into a first adapted voltage, such as 12V, to meet the requirements of different load nodes, especially other load nodes (such as fans, etc.) except the central processing unit (CPU, Central Processing Unit) and graphics processing unit (GPU, Graphics Processing Unit) nodes.

[0092] In this way, the first power adaptation module 51 provides the required voltage for these non-critical load nodes to ensure their stable operation. The power supply module is responsible for further converting the first adapted voltage into a preset voltage to supply the required power for high-power consumption load nodes such as CPUs and GPUs. The power supply module provides a stable power supply through appropriate voltage regulation according to the requirements of these load nodes to ensure its efficient operation.

[0093] As Figure 6 , this embodiment skips the scheme of the intermediate conversion voltage 54VDC, cancels the voltage conversion link from 380VDC to 54VDC, directly steps down 380VDC to 12VDC to supply power to the fan board and other load nodes, and is converted by the power supply module to supply power to the CPU / GPU core. This scheme cancels the voltage intermediate conversion link, reduces one conversion module, reduces the cost and improves the power conversion efficiency at the same time.

[0094] This design enables the power distribution board 13 to flexibly provide the required voltage for different types of load nodes. At the same time, by centrally managing the power conversion process, it improves the efficiency of power distribution and reduces energy loss.

[0095] As Figure 5 and Figure 7As shown, as an alternative embodiment, the power distribution board 13 further includes: at least one second power adapter module 52. The input end of each second power adapter module 52 is connected to the output end of the first power adapter module 51, and its output end is connected to the power supply end of at least one first preset load node corresponding to itself. The second power adapter module 52 is configured to convert the first adapted voltage into a second adapted voltage to provide power for at least one first preset load node connected to itself.

[0096] In this embodiment, by introducing at least one second power adapter module 52, the power distribution board 13 further optimizes the accuracy and flexibility of power distribution. Each second power adapter module 52 receives the first adapted voltage from the first power adapter module 51 (for example, the first power adapter module 51 can only convert the high-voltage direct current output by the busbar 12 into a first adapted voltage of 54V (this is because some servers, due to hardware or structural limitations, require a first adapted voltage of 54V or can only obtain a first adapted voltage of 54V)), and converts it into a second adapted voltage (such as 12V) to meet the power supply requirements of specific load nodes. The output end of the second power adapter module 52 is connected to the corresponding first preset load nodes to provide a suitable voltage supply for these nodes. The first preset load nodes include other loads except the central processing unit (CPU) and / or the graphics processing unit (GPU), such as memory modules, memories, etc.

[0097] In this embodiment, first, 380VDC is reduced to 54VDC. Usually, the CPU / GPU has the largest load, so 54V can be directly converted to supply power to the chip core. In this case, although the intermediate voltage of 54V is retained, the main load path from 380VDC to the CPU / GPU only undergoes two-level conversion, and the power efficiency is higher. In addition, the voltage of 54V is higher than 12V, so the on-board current flowing through is smaller, and the resulting path loss is also lower.

[0098] Through this design, the power distribution board 13 can adaptively distribute the power adapter to each node according to the voltage requirements of different load nodes, effectively reducing energy loss and improving the overall efficiency and stability of the power supply system. At the same time, this design makes the power distribution board 13 have higher flexibility and scalability, can adapt to the needs of different hardware configurations, and ensures that each load node can obtain stable power supply without affecting other nodes.

[0099] As an alternative embodiment, it further includes: a battery module, whose output end is connected to the busbar 12. The battery module is configured to provide backup power for the busbar 12 when the power supply is interrupted and the server is operating normally.

[0100] In this embodiment, the battery module is configured as a backup power source to ensure that the server can continue to operate for a period of time in the event of a power supply interruption, preventing service interruption or data loss caused by a power outage.

[0101] The battery module may include multiple battery sub-modules to provide sufficient energy reserves to ensure that when the main power supply (i.e., the power supply) fails to supply power, the server can continue to operate relying on the electrical energy of the battery module. The design of the battery module can seamlessly switch to the backup power source when the main power supply fails, thus providing stable power support for the busbar copper row 12 and maintaining the working state of the server.

[0102] The battery module generally charges when the server is operating normally and has a long lifespan to ensure that sufficient power can be provided in the event of a power interruption, usually used to maintain the basic operation requirements of the server before the power is restored.

[0103] With this design, the operation of the server no longer completely depends on the external power supply, thereby improving the reliability and stability of the system, especially ensuring service continuity in the event of a power failure or emergency.

[0104] As an alternative embodiment, it further includes: a monitoring module, whose input terminal is connected to the busbar copper row 12. The monitoring module is configured to obtain the working parameters of the busbar copper row 12 and determine whether to control the server to shut down according to the working parameters; the working parameters include working voltage, and / or working current, and / or working temperature and / or energy loss.

[0105] As an alternative embodiment, the monitoring module is specifically configured to control the server to shut down in response to the working voltage being greater than the upper limit value of the preset voltage range or less than the lower limit value of the preset voltage range, or in response to the working current being greater than the current threshold, or in response to the working current being greater than the temperature threshold, or in response to the energy loss being greater than the preset loss.

[0106] In this embodiment, the design purpose of the monitoring module is to monitor the operating state of the server in real time to ensure that the server can automatically take measures to protect the system security in the event of an abnormal situation. The monitoring module is connected to the busbar copper row 12 to continuously obtain the working parameters related to the server power supply system. These working parameters include working voltage, working current, working temperature and energy loss, which can comprehensively reflect the operating condition of the server power module.

[0107] The monitoring module analyzes based on these parameters. When some operating parameters exceed the preset range, the monitoring module will take corresponding measures to prevent the server from malfunctioning or being damaged. Specifically, if the operating voltage exceeds the upper and lower limits of the preset voltage range, or the operating current exceeds the current threshold, or the operating temperature reaches the set temperature threshold, or the energy loss exceeds the set preset loss value, the monitoring module will determine that there is a potential danger in the system and trigger the server shutdown operation, thereby avoiding permanent damage to the server hardware caused by abnormal power supply, overload, overheating, etc.

[0108] In this embodiment, the security of the system is improved, and the server can be shut down in time when abnormal power supply or other failures occur, protecting the device from more serious damage.

[0109] As an alternative embodiment, the monitoring module may include a voltage monitoring unit, a current monitoring unit, a temperature monitoring unit, and an energy loss monitoring unit. The voltage monitoring unit is used to collect the operating voltage on the busbar copper row 12 in real time to ensure that the voltage is maintained within the preset range; the current monitoring unit is used to monitor the current in the busbar copper row 12 to detect in time whether it exceeds the set current threshold; the temperature monitoring unit is responsible for monitoring the temperature of the busbar copper row 12 and other key components to avoid equipment failures caused by overheating; the energy loss monitoring unit is used to evaluate the energy loss during the operation of the system to ensure system efficiency and prevent excessive energy waste. Through the collaborative work of these units, the monitoring module can comprehensively monitor the operating status of the server power supply system and make a decision on whether to shut down based on real-time data, thereby ensuring the safe and stable operation of the device.

[0110] As an alternative embodiment, the temperature adjustment strategy of the temperature detection unit may include dynamically adjusting the operating status of the air-cooling or liquid-cooling system based on the real-time temperature data inside the server cabinet and on the busbar copper row 12. When it is detected that the temperature exceeds the set safety threshold, the temperature detection unit can trigger the fan of the system to accelerate or the liquid-cooling pump to operate more efficiently, thereby accelerating heat dissipation and reducing the system temperature; if the temperature is lower than the set range, the operating speed of the cooling equipment can be slowed down to optimize energy consumption. In addition, the temperature detection unit can also automatically adjust the temperature control strategy in combination with the server load condition, and adjust the operating efficiency of the cooling system according to different working load stages and external environmental temperature changes to achieve precise temperature control management and optimal use of energy. This strategy helps to extend the service life of the device and ensure that the system can still operate stably under high load conditions.

[0111] As an alternative embodiment, the method for determining the volume of the busbar copper row 12 is: determine the volume of the busbar copper row 12 according to the total power of the server, the voltage of the high-voltage direct current on the busbar copper row 12, and the electrical performance parameters of the busbar copper row 12.

[0112] As an alternative embodiment, determining the volume of the busbar 12 based on the total power of the server, the voltage of the high-voltage direct current on the busbar 12, and the electrical performance parameters of the busbar 12 includes:

[0113] According to determine the volume of the busbar 12;

[0114] Volume is the volume of the busbar 12, P total is the total power of the server, U is the voltage of the high-voltage direct current on the busbar 12, ρ is the volume resistivity of copper, L is the length of the busbar 12, P loss is the loss limit of the busbar 12, U drop is the voltage drop limit of the busbar 12, I lim is the current-carrying capacity limit per unit cross-sectional area of copper.

[0115] In this embodiment, the method for determining the volume of the busbar 12 combines multiple parameters to ensure that the busbar 12 can safely and efficiently support the power requirements of the server. First, the total power of the server, the high-voltage direct current voltage on the busbar 12, and the electrical performance parameters of the busbar 12, such as the volume resistivity of copper, the length L, etc., all affect the design of the busbar 12. Specifically, the volume of the busbar 12 needs to meet several key limiting conditions:

[0116] Loss limit (P loss ): The loss of the busbar 12 must be controlled within a certain range, that is, the heat generated when the current passes through the copper bar should not exceed the set loss limit. The loss is proportional to the square of the current, so the formula is used to calculate the volume to ensure that the heat generated when the current passes through the copper bar does not exceed the predetermined safety value;

[0117] Voltage drop limit (U drop ): A voltage drop will occur when the current passes through the copper bar, and the voltage drop of the busbar 12 should not exceed the set limit. According to the formula , it can be ensured that the volume of the copper bar is large enough to reduce the voltage drop when the current passes through and maintain the stability of the power supply;

[0118] Current-carrying capacity (I lim ): The cross-sectional area of the copper bar should be able to carry the current flowing through it to avoid overheating or damage. The formula is used to determine whether the current-carrying capacity of the copper bar meets the requirements under the length and cross-sectional area of the busbar 12.

[0119] By comprehensively considering the above factors, the appropriate volume of the busbar copper bar 12 can finally be calculated, enabling it to effectively transmit the required current while maintaining stable temperature and voltage, ensuring the safe and efficient operation of the system.
