Description

Technical Field

[0001] The present invention relates to the field of server power supply, and in particular 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 speech recognition (ASR), the demand for computing power has increased dramatically, promoting 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 50kW per computing cabinet, which puts strict requirements on the power supply system. At the same time, a series of environmental protection concepts have been proposed, requiring high-energy consumption data centers to improve power efficiency and reduce power supply efficiency.

[0003] The traditional power supply architecture has inherent energy loss due to its AC transmission method. Specifically, AC will generate heat loss due to resistance, electromagnetic induction and capacitance effects during long-distance transmission, and it needs to be adapted to the needs of different devices through multiple transformations and conversions, which further increases energy losses. These losses are particularly significant in high power density scenarios.

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

[0055] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] First, as Figure 1 As shown, the present application provides a server power supply system, which is 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 a 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; the 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, and supply power to the load node.

[0057] The traditional AC power supply architecture will inevitably encounter losses such as resistance, electromagnetic induction and capacitance effects during long-distance power transmission, and energy will be gradually consumed during multiple voltage conversions, which makes 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 this application aims to solve the demand for efficient power supply of high-power and high-energy consumption servers, improve power transmission efficiency, and reduce energy loss in traditional AC power supply systems. This application optimizes power supply efficiency by adopting high-voltage DC power transmission and reducing multiple conversion links.

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

[0060] High voltage direct current is transmitted through the busbar copper bar 12. As a transmission medium, the busbar copper bar 12 has a low resistance and a high current carrying capacity, which ensures that the power loss is minimized during the transmission process. Due to the excellent conductivity of copper, it can withstand a large current and avoid the additional heat generated by the current flowing through the high resistance material in the conventional power supply method.

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

[0062] Among them, the voltage range of high-voltage direct current can usually be selected between 300V and 1000V, such as intermediate voltage values ​​such as 380V. Selecting this voltage range as the voltage for high-voltage direct current transmission can reduce the energy loss caused by resistance during transmission while ensuring low current. Compared with low-voltage direct current or alternating current, higher voltage can effectively reduce the current intensity, and the reduction in current means that the heat loss caused by resistance during transmission is also reduced. This design not only improves the efficiency of power transmission, but also effectively reduces the operating temperature of lines and equipment, extends the service life of the system, and reduces the burden on the environment caused by energy waste. Therefore, selecting high-voltage direct current between 300V and 1000V as the transmission voltage not only technically realizes efficient and low-loss power transmission, but also meets the high requirements of modern high-computing power equipment for power supply. It overcomes the limitations of 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 reduces the energy waste caused by various losses in the transmission of alternating current. By reducing the intermediate links, especially avoiding the complex process of multiple transformations and conversions in the traditional architecture to adapt to the needs of different equipment, this design not only improves the transmission efficiency of electricity technically, but also meets the current requirements for energy efficiency and carbon emission control, and adapts to the urgent needs of large-scale data centers and high-performance servers for green and energy-saving power supply. Therefore, the server power supply system of this application can not only significantly improve the power transmission efficiency and meet the power needs of modern high-computing power and high-energy consumption servers, but also help reduce the negative impact on the environment.

[0064] like Figure 2As shown, as an optional embodiment, the server also includes a server cabinet; the power conversion module 11 is arranged in a first preset area inside the server cabinet, the power distribution board 13 is arranged in a second preset area inside the server cabinet, the load node is arranged in a third preset area inside the server cabinet, the busbar 12 is arranged at the back of the server cabinet, and the output end of the power conversion module 11 is connected to the busbar 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 up multiple preset areas inside the server cabinet. The power conversion module 11 is set in the first preset area inside the server cabinet, which is specifically used to handle the input and conversion tasks of the external power supply. 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, which is responsible for converting the input high-voltage direct current into a voltage suitable for the requirements of different load nodes to ensure that each load node can obtain accurate power supply. The load nodes are set in the third preset area inside the server cabinet. These nodes may be different computing units, such as a central processing unit, a graphics processing unit, etc., which require power supplies of different voltages and currents. The busbar copper bar 12 is set at the back of the server cabinet 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 modules in the server into an integral server cabinet, so that the functions of each area can be clearly divided, while improving the efficiency and safety of power transmission and facilitating daily maintenance and management.

[0067] like Figure 3 As shown, as an optional embodiment, the server further includes a power cabinet and a computing cabinet; the power conversion module 11 is arranged inside the power cabinet, the power distribution board 13 and the load node are arranged inside the computing cabinet, and the busbar copper bar 12 is arranged at the back of the computing cabinet; the output end of the power conversion module 11 is connected to the power supply cabinet through a cable (i.e. Figure 3 The high-voltage copper cable in the circuit is connected to the busbar copper bar 12.

[0068] In this embodiment, the structural design of the server system adopts a separated layout to optimize power distribution and improve the operating efficiency of the overall system. The power cabinet and the computing cabinet are designed as independent modules respectively, and the power conversion module 11 is centrally arranged inside the power cabinet, which is 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 part, and can also achieve efficient operation of the power conversion process. The power distribution board 13 and the load nodes are located inside the computing cabinet, specifically providing appropriate power for each load node in the computing cabinet. The busbar copper bar 12, as a medium for power transmission, is set at the back of the computing cabinet to optimize space utilization and improve heat dissipation. The busbar copper bar 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 part and the computing part do not interfere with each other, effectively reducing the impact of power supply interference on the computing module, while achieving more flexible and efficient power transmission and management.

[0071] like Figure 4 As 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 AC power output by the power supply into an intermediate DC power; 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 12, and the second power conversion sub-module 43 is configured to convert the intermediate DC power into a high-voltage DC power having a voltage higher than a preset voltage.

[0072] In this embodiment (recorded as the first embodiment 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. Due to its periodic fluctuations, alternating current is not suitable for direct use in efficient power transmission, so it must be converted. The first sub-module converts alternating current into direct current through processes such as rectification and filtering, and provides intermediate direct current, which can be further increased in subsequent steps. As a stable voltage source, intermediate direct current has less fluctuations and interference, and is suitable for subsequent high-voltage conversion.

[0073] Next, the second power conversion submodule 43 takes over the intermediate DC output by the first submodule and converts it into high-voltage DC. At this time, the key task of the second submodule is to increase the voltage of the intermediate DC to above the preset voltage through boost conversion, thereby forming high-voltage DC suitable for long-distance transmission. High-voltage DC has a smaller current than low-voltage DC, 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 avoids the energy loss that may be caused by directly converting from AC to high-voltage DC. The first stage provides a stable voltage foundation suitable for further boosting for the second stage through the conversion of intermediate DC, thereby achieving efficient voltage conversion and energy transmission. This staged conversion method not only improves the efficiency of power transmission, but also reduces heat generation and energy loss during the power conversion process, thereby improving the performance of the entire system.

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

[0076] In this embodiment, the power conversion module 11 further selects different power conversion paths according to different types of power supplies by introducing a switching switch 41, 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 work normally under different input conditions and achieve 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 power type of the input terminal, the switching switch 41 will decide which path to turn on. When the power type of the input terminal is suitable for the working requirements of the first power conversion sub-module 42 (that is, when the input is AC power), the switching switch 41 will turn on the first path, allowing the current of the power supply to enter the first power conversion sub-module 42 through the path for conversion. On the other hand, when the input power type is more suitable for the second power conversion sub-module 43 (that is, when the input is DC power), the switching switch 41 will switch to the second path, and the power will be introduced into the second power conversion sub-module 43 through the second path for further voltage conversion.

[0078] Figure 4In the figure, AC power and DC power are switched by switching switch 41. If AC power is input, it will be rectified by the first power conversion submodule 42 (such as AC / DC (AC / DC)) to output an intermediate DC voltage, and then it will be stepped down, isolated and stabilized by the second power conversion submodule 43 (such as DC / DC (DC / DC)), and finally it will be filtered by the filter module to output stabilized and isolated high-voltage DC power; if DC power is input, after switching by switching switch 41, the rectification link of the first power conversion submodule 42 can be skipped, and the step-down and filtering modules of the second power conversion submodule 43 in the AC case can be reused, and finally 380V DC voltage is also output. The reuse of 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 inputs, such as alternating current or direct current of different specifications, ensuring that the power conversion module 11 can effectively provide the required voltage under 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 a stable supply of electricity under a variety of power supply conditions. In addition, this switching mechanism avoids energy waste or system failures caused by mismatched power types, thereby improving the reliability and stability of the overall system.

[0080] As an optional 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, and 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, and 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 (recorded as the second embodiment 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 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 rectification, filtering and other processes, and further boosts it to high-voltage direct current above the preset voltage. This conversion method can reduce the current loss in high-power transmission and improve the power transmission efficiency of the system, especially in high-power density application scenarios, and can ensure efficient supply of electricity.

[0082] At the same time, the second power conversion submodule 43 receives the DC power from the second power supply and converts it into a high-voltage DC power with a voltage higher than the preset voltage. Unlike the first power conversion submodule 42, the second power conversion submodule 43 starts directly from the DC power supply, avoiding the conversion process from AC to DC, thereby reducing additional energy loss. This design also uses boost technology to increase the input DC power to the required high-voltage DC power so that it can be transmitted to the busbar copper bar 12 in the system to achieve stable and efficient power supply.

[0083] As an optional embodiment, the power conversion module 11 also includes: a switching switch 41, whose first input end is connected to the first power supply, whose second input end is connected to the second power supply, whose first output end is connected to the input end of the first power conversion sub-module 42, and whose second output end is connected to the input end of the second power conversion sub-module 43; the switching switch 41 is configured to turn on the first path or the second path according to the power type output by the power supply at its own input end; the first path is the path between the first input end and the first output end of the switching switch 41, and the second path is the path between the second input end and the second output end of the switching switch 41.

[0084] In order to further improve the flexibility and adaptability of the system, the power conversion module 11 also introduces a switching switch 41. The function of the switching 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 AC, the switching switch 41 will turn on the first path and transmit the AC to the first power conversion sub-module 42 for conversion; and when the second power supply is DC, the switching switch 41 will turn on the second path and transmit the DC to the second power conversion sub-module 43 for processing. This design allows the system to dynamically select the most appropriate 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 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 actual conditions, 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 loss and system failures.

[0086] The main difference between the above-mentioned embodiment 1 and embodiment 2 lies in the method and steps of power conversion. Embodiment 1 adopts a staged power conversion process, in which the AC power of the power supply is first converted into intermediate DC power by the first power conversion submodule 42, and then the intermediate DC power is boosted to high-voltage DC power by the second power conversion submodule 43. In this process, the first power conversion submodule 42 is responsible for rectifying the AC power into DC power, providing a stable intermediate DC power supply for subsequent boosting. In embodiment 1, the switching switch 41 conducts the first path or the second path according to the type of power supply at the input end, but these two paths are connected to the input ends of the first power conversion submodule 42 and the second power conversion submodule 43 respectively, and the first power conversion submodule 42 is responsible for converting the AC power into intermediate DC power, and the second power conversion submodule 43 boosts the intermediate DC power into high-voltage DC power. Therefore, the role of the switching switch 41 in embodiment 1 is mainly to select the type of input power (AC or DC) and determine which conversion path the power supply enters, so as to ensure that the power system automatically adjusts the working mode according to the power supply type.

[0087] In contrast, the second embodiment directly converts the AC power of the first power supply and the DC power of the second power supply into high-voltage DC power respectively. The function of the 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 AC power into high-voltage DC power, and the second power conversion sub-module 43 converts the DC power into high-voltage DC power. Therefore, the selection of the switch 41 directly affects the input of the power supply, and the type of power conversion (AC to DC or DC to high-voltage DC) is already 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 types, and at the same time reduce energy loss and improve conversion efficiency through staged power conversion (first converting AC power into intermediate DC power, and then boosting the intermediate DC power into high-voltage DC power).

[0089] In the second embodiment, 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 type, avoiding the additional complexity in the multi-stage conversion process. Since each power conversion sub-module directly processes the power supply (AC or DC) suitable for its input type, the system processing delay can be reduced and the response speed can be improved, thereby ensuring that the required high-voltage DC power is provided quickly and stably under different power conditions.

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

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

[0092] In this way, the first power adapter module 51 provides the required voltage for these non-critical load nodes to ensure that they can operate stably. The power supply module is responsible for further converting the first adaptation voltage into a preset voltage to provide the required power for high-power load nodes such as CPU and GPU. The power supply module provides a stable power supply through appropriate voltage regulation according to the needs of these load nodes to ensure their efficient operation.

[0093] like Figure 6 This embodiment skips the intermediate conversion voltage 54VDC solution, cancels the voltage conversion link from 380VDC to 54VDC, and directly steps down the voltage from 380VDC to 12VDC to power the fan board and other load nodes, and then converts it into power for the CPU / GPU core through the power supply module. This solution cancels the intermediate voltage conversion link, reduces one conversion module, reduces costs and improves power conversion efficiency.

[0094] This design enables the power distribution board 13 to flexibly provide the required voltage for different types of load nodes, while improving the efficiency of power distribution and reducing energy loss by centrally managing the power conversion process.

[0095] like Figure 5 and Figure 7As shown, as an optional embodiment, the power distribution board 13 also 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 the output end is connected to the power end of at least one first preset load node corresponding to itself; the second power adapter module 52 is configured to convert the first adaptation voltage into the second adaptation voltage to provide power for at least one first preset load node connected to itself.

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

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

[0098] Through this design, the power distribution board 13 can adapt and distribute power to each node according to the voltage requirements of different load nodes, effectively reduce energy loss, and improve the overall efficiency and stability of the power supply system. At the same time, this design makes the power distribution board 13 more flexible and scalable, and can adapt to the needs of different hardware configurations, ensuring that each load node obtains a stable power supply without affecting other nodes.

[0099] As an optional embodiment, it also includes: a battery module, whose output end is connected to the busbar copper bar 12, and the battery module is configured to provide backup power for the busbar copper bar 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 when the power supply is interrupted, so as to prevent service interruption or data loss due to power outage.

[0101] The battery module may include multiple battery submodules to provide sufficient energy reserves to ensure that when the main power source (i.e., the power supply) fails to provide power, it can rely on the power of the battery module to continue to operate. The battery module is designed to be able to seamlessly switch to the backup power source when the main power source fails, thereby providing stable power support for the busbar copper bar 12 to keep the server in working condition.

[0102] The battery module is generally charged when the server is operating normally and has a long life to ensure that it can provide sufficient power when a power outage occurs. It is usually used to maintain the basic operating needs of the server before power is restored.

[0103] Through this design, the operation of the server is no longer completely dependent on an external power supply, thereby improving the reliability and stability of the system, especially ensuring service continuity in the event of power failure or emergencies.

[0104] As an optional embodiment, it also includes: a monitoring module, whose input end is connected to the busbar copper bus 12, and the monitoring module is configured to obtain the working parameters of the busbar copper bus 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 optional embodiment, the monitoring module is specifically configured to control the server to shut down in response to the operating voltage being greater than the upper limit of a preset voltage range or less than the lower limit of a preset voltage range, or in response to the operating current being greater than a current threshold, or in response to the operating current being greater than a temperature threshold, or in response to energy loss being greater than a preset loss.

[0106] In this embodiment, the monitoring module is designed to monitor the operating status of the server in real time to ensure that the server can automatically take measures to protect the safety of the system when an abnormal situation occurs. The monitoring module is connected to the busbar copper bar 12 to continuously obtain operating parameters related to the server power system. These operating parameters include operating voltage, operating current, operating temperature and energy loss, which can fully reflect the operating status of the server power module.

[0107] The monitoring module analyzes these parameters, and when certain 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 preset loss value, the monitoring module will determine that the system is potentially dangerous and trigger the server shutdown operation, thereby avoiding power supply abnormalities, overloads or overheating problems that cause permanent damage to the server hardware.

[0108] This embodiment improves the security of the system and can shut down the server in time when power supply anomalies or other failures occur, thereby protecting the equipment from more serious damage.

[0109] As an optional 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 working voltage on the bus copper bus 12 in real time to ensure that the voltage is maintained within a preset range; the current monitoring unit is used to monitor the current in the bus copper bus 12 and promptly detect whether it exceeds the set current threshold; the temperature monitoring unit is responsible for monitoring the temperature of the bus copper bus 12 and other key components to avoid equipment failures caused by overheating; the energy loss monitoring unit is used to evaluate the energy loss of the system during operation 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 system, and make decisions on whether to shut down based on real-time data, thereby ensuring the safety and stable operation of the equipment.

[0110] As an optional embodiment, the temperature adjustment strategy of the temperature detection unit may include dynamically adjusting the working state of the air cooling or liquid cooling system based on the real-time temperature data in the server cabinet and the busbar copper bus 12. When the temperature is detected to exceed the set safety threshold, the temperature detection unit may trigger the system's fan acceleration or the liquid cooling pump to increase efficiency, thereby accelerating heat dissipation and reducing the system temperature; if the temperature is lower than the set range, the energy consumption can be optimized by slowing down the working speed of the cooling equipment. In addition, the temperature detection unit can also automatically adjust the temperature control strategy in combination with the server load conditions, and adjust the working efficiency of the cooling system according to different workload stages and external ambient temperature changes, so as to achieve precise management of temperature control and optimal use of energy. This strategy helps to extend the service life of the equipment and ensure that the system can still maintain stable operation under high load conditions.

[0111] As an optional embodiment, the volume of the busbar copper bar 12 is determined by: determining the volume of the busbar copper bar 12 according to the total power of the server, the voltage of the high-voltage direct current on the busbar copper bar 12, and the electrical performance parameters of the busbar copper bar 12.

[0112] As an optional embodiment, the volume of the busbar copper bar 12 is determined according to the total power of the server, the voltage of the high-voltage direct current on the busbar copper bar 12, and the electrical performance parameters of the busbar copper bar 12, including:

[0113] according to Determine the volume of the busbar copper bar 12;

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

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

[0116] Loss Limitation (P loss ): The loss of the busbar copper bar 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 busbar does not exceed the predetermined safety value;

[0117] Voltage drop limit (U drop ): When current passes through the copper busbar, a voltage drop will occur. The voltage drop of the busbar copper busbar 12 should not exceed the set limit. According to the formula , which can ensure that the volume of the copper busbar is large enough to reduce the voltage drop when the current passes through and maintain a stable power supply;

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

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