Description

Technical Field

[0001] The present invention relates to the technical field of immersion cooling, and in particular to an immersion server operation control method and system. Background Art

[0002] With the rapid growth of modern information technology and big data processing needs, the scale and computing density of data centers are constantly increasing, and traditional air cooling methods are gradually exposing their limitations. In high-density computing environments, air cooling is not only inefficient, but also difficult to cope with the high heat flux density generated by high-power processors and graphics cards. Immersion cooling, as an efficient thermal management technology, has gradually entered people's field of vision. By completely immersing the hardware equipment in a coolant with excellent insulation and thermal conductivity, the heat generated by the equipment can be directly and quickly removed, which can not only improve the cooling efficiency, but also reduce the energy consumption of traditional cooling equipment such as fans and air conditioners. In recent years, immersion cooling technology has been widely studied in major data centers and laboratories, promoting innovations in energy conservation and emission reduction and improving computing performance.

[0003] However, immersion cooling technology still has many shortcomings in thermal management. Most immersion cooling systems lack refined management tools for liquid level monitoring. The sensor technology currently used is often unable to accurately capture subtle changes in the liquid level. Especially when running at high load, liquid level fluctuations may lead to untimely coolant supply, increasing the risk of thermal runaway of the system. Insufficient control of liquid level fluctuations directly affects the efficiency and safety of the cooling system. The coolant flow rate adjustment technology has evolved relatively slowly. Existing technologies usually rely on preset circulation speeds and fail to dynamically adjust the flow rate according to real-time heat loads, resulting in limited energy efficiency and waste of resources. When the system detects an overload or high temperature, traditional solutions cannot respond quickly and need to be readjusted manually or manually, increasing the probability of equipment overheating and damage. The problem of coolant leakage has not been effectively solved in existing technologies. Existing systems do not yet have mature automatic detection and response mechanisms. The system cannot quickly locate the problem and take effective measures when the liquid level increase rate or flow rate deviation is too large, increasing maintenance costs and the risk of equipment damage. Summary of the invention

[0004] In view of the above-mentioned problems, the present invention is proposed.

[0005] Therefore, the technical problems solved by the present invention are: the existing immersion cooling technology has the problems of inaccurate liquid level control, insufficient optimization of coolant flow rate, untimely coolant leakage detection, and how to achieve a more efficient and reliable cooling control system through intelligent monitoring and automatic adjustment mechanism.

[0006] To solve the above technical problems, the present invention provides the following technical solutions: an immersion server operation control method, comprising determining whether the liquid level is higher than a preset start-up liquid level, activating the coolant circulation system to confirm liquid flow; optimizing the coolant inlet speed according to feedback from a flow rate sensor, and monitoring the liquid level stability in the server cabinet; determining whether the coolant is leaking based on the liquid level growth rate and flow rate deviation, triggering an alarm when the liquid level is insufficient, and automatically adjusting the liquid level and circulation time.

[0007] As a preferred solution of the immersion server operation control method described in the present invention, the determination of whether the liquid level is higher than the preset starting liquid level includes automatically detecting the status of the liquid level sensor, collecting the liquid level data in the server cabinet after receiving the power-on command, and confirming whether the liquid level is higher than the preset starting liquid level after the liquid level detection is completed. If the liquid level is lower than the preset liquid level, the system sends an alarm to the operator and terminates the power-on process. If the liquid level meets the preset requirements, the system activates the coolant circulation system to confirm that the coolant covers the entire server component. The system dynamically adjusts the preset starting liquid level according to the installation height of the server, optimizes the sensor accuracy under different load conditions, and confirms that the sensor adapts to the temperature and liquid level fluctuations in the cabinet during detection, and triggers an emergency shutdown when the preset threshold is exceeded.

[0008] As a preferred embodiment of the immersion server operation control method described in the present invention, the activating the coolant circulation system to confirm the liquid flow includes automatically detecting the current state of the coolant circulation system, starting the circulation pump immediately after the system detects that the liquid level meets the requirements, and confirming that the system reaches the preset flow rate within the set time. When the circulation pump fails to reach the target flow rate within the specified time after starting, the system activates the standby circulation pump and re-detects the flow rate change to confirm that the coolant flows stably before the server is started. Multiple detection modes are set in the liquid level and flow rate detection, and redundant flow rate sensors are used to confirm whether the actual flow rate is consistent with the target flow rate. If it is detected that the liquid level fluctuation exceeds the preset range or the circulation system fails to flow stably, the system stops the circulation operation and issues an alarm.

[0009] As a preferred solution of the immersion server operation control method described in the present invention, wherein: the optimization of the coolant inlet speed according to the flow rate sensor feedback includes calculating the real-time inlet rate of the coolant in the server cabinet according to the flow rate sensor feedback data, automatically adjusting the coolant inlet flow rate, confirming the sufficient supply of coolant under high load conditions of the server, and reducing the liquid supply when the load is reduced. The system adjusts the coolant flow rate through a PID control algorithm, and adjusts the coolant inlet rate in real time according to different liquid level and temperature data. When the inlet rate exceeds the set range, the system automatically increases or decreases the coolant flow rate.

[0010] As a preferred solution of the immersion server operation control method described in the present invention, the monitoring of the stable state of the liquid level in the server cabinet includes, after the coolant circulation system is started, real-time monitoring of the liquid level changes in the cabinet and recording the liquid level fluctuations per second, analyzing the stability of the liquid level within a specified time, and judging whether the liquid level fluctuations meet the stability conditions. When the liquid level meets the set stability conditions, the server is turned on. If the liquid level fluctuations do not reach the stability standard within the set time, the system automatically increases the liquid inlet speed, re-detects the liquid level changes, and allows the server to start up only after confirming that the liquid level is stable.

[0011] As a preferred solution of the immersion server operation control method described in the present invention, the method of judging whether the coolant is leaking based on the liquid level growth rate and flow rate deviation includes the system automatically monitoring the flow rate changes of the coolant in the inlet and outlet pipes, comparing the difference between the actual liquid inlet speed and the liquid outlet speed fed back by the flow rate sensor, and determining that the coolant may have leaked when the liquid level growth rate is lower than a predetermined range. After detecting that the liquid level growth rate is lower than a preset threshold, the system automatically issues an alarm and activates a redundant circulating liquid flow detection system when the coolant flow rate deviation exceeds the set threshold, further confirming that the liquid level change is caused by a coolant leakage, and promptly notifying maintenance personnel to handle the fault.

[0012] As a preferred solution of the immersion server operation control method described in the present invention, wherein: the alarm is triggered when the liquid level is insufficient, and the liquid level and cycle time are automatically adjusted, including the system immediately triggering an alarm signal when detecting insufficient liquid level, and automatically calculating the required liquid inlet rate, automatically adjusting the liquid inlet flow rate and cycle time according to actual conditions, confirming that the coolant quickly recovers to the preset starting liquid level, and when the system detects that the coolant has recovered to a safe liquid level, it automatically reduces the liquid inlet speed, returns to the normal cycle time, and re-detects the liquid level stability, and confirms that the coolant fully covers the server components and then lifts the alarm.

[0013] Another object of the present invention is to provide an immersion server operation control system, which can optimize the coolant inlet speed according to the feedback of the flow rate sensor and monitor the stable state of the liquid level in the server cabinet, thereby solving the problem that the current immersion cooling technology contains the lack of flexibility and real-time performance of the coolant flow rate control.

[0014] As a preferred solution of the immersion server operation control system described in the present invention, it includes: a liquid level detection activation module, a flow rate feedback optimization module, and a leakage judgment alarm module.

[0015] The liquid level detection activation module is used to determine whether the liquid level is higher than the preset starting liquid level, and activate the coolant circulation system to confirm liquid flow; the flow rate feedback optimization module is used to optimize the coolant inlet speed according to the feedback from the flow rate sensor, and monitor the liquid level stability in the server cabinet; the leakage judgment alarm module is used to determine whether the coolant is leaking based on the liquid level growth rate and flow rate deviation, and trigger an alarm when the liquid level is insufficient, and automatically adjust the liquid level and circulation time.

[0016] A computer device includes a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement a method for controlling operation of an immersive server.

When the server load is high, the system can ensure sufficient coolant distribution, effectively preventing performance degradation or hardware damage caused by overheating, and when the load is reduced, the system automatically reduces the liquid supply, thereby saving energy. The flexible flow rate optimization mechanism not only improves the cooling efficiency, but also reduces the operating cost. By real-time monitoring of the liquid level changes in the cabinet, the system The invention can ensure the stability of the liquid level, reduce equipment failures caused by liquid level fluctuations, ensure the safe and stable operation of the server, judge whether the coolant is leaking based on the liquid level growth rate and flow rate deviation, trigger an alarm when the liquid level is insufficient, automatically adjust the liquid level and circulation time, and realize early leakage detection by real-time monitoring of flow rate changes and comparing the difference between the actual liquid inlet speed and the liquid outlet speed. When the system detects that the liquid level growth rate is lower than the predetermined range, it will immediately issue an alarm and activate the redundant flow rate sensor to further confirm the problem. The rapid response capability effectively improves the safety of the system and reduces the potential risks caused by coolant leakage. When the liquid level is insufficient, the system will automatically adjust the liquid inlet flow rate and circulation time to quickly restore the liquid level to a safe standard. The self-adjustment capability ensures that the system can respond and repair quickly when an abnormal situation occurs, thereby reducing the equipment failure rate and improving the overall stability and reliability of the data center.

Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other accompanying drawings can be obtained based on these accompanying drawings without paying creative work.

[0022] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0023] Example 1, reference Figure 1 , as an embodiment of the present invention, provides an immersive server operation control method, comprising:

[0024] S1: Determine whether the liquid level is higher than the preset start-up level, activate the coolant circulation system to confirm the liquid flow.

[0025] Furthermore, determining whether the liquid level is higher than the preset starting liquid level includes automatically detecting the status of the liquid level sensor, collecting the liquid level data in the server cabinet after receiving the power-on command, and confirming whether the liquid level is higher than the preset starting liquid level after the liquid level detection is completed. If the liquid level is lower than the preset liquid level, the system sends an alarm to the operator and terminates the power-on process. If the liquid level meets the preset requirements, the system activates the coolant circulation system to confirm that the coolant covers the entire server component. The system dynamically adjusts the preset starting liquid level according to the installation height of the server, and optimizes the sensor accuracy under different load conditions, confirming that the sensor adapts to the temperature and liquid level fluctuations in the cabinet during detection, and triggers an emergency shutdown when the preset threshold is exceeded.

[0026] It should be noted that activating the coolant circulation system to confirm liquid flow includes automatically detecting the current state of the coolant circulation system, starting the circulation pump immediately after the system detects that the liquid level meets the requirements, and confirming that the system reaches the preset flow rate within the set time. When the circulation pump fails to reach the target flow rate within the specified time after starting, the system activates the backup circulation pump and re-detects the flow rate change to confirm that the coolant flows stably before the server is turned on. Multiple detection modes are set in the liquid level and flow rate detection, and redundant flow rate sensors are used to confirm whether the actual flow rate is consistent with the target flow rate. If it is detected that the liquid level fluctuation exceeds the preset range or the circulation system fails to flow stably, the system stops the circulation operation and issues an alarm.

[0027] It should also be noted that by judging whether the liquid level is higher than the preset starting liquid level, precise control of the starting conditions of the immersion server cooling system is achieved. By automatically detecting the status of the liquid level sensor and collecting the liquid level data immediately after receiving the power-on command, it is ensured that the system is started only when the liquid level meets the safety conditions, avoiding the low cooling efficiency and potential equipment damage risks caused by insufficient liquid level. The system dynamically adjusts the preset starting liquid level according to the installation height of the server, optimizes the sensor accuracy to adapt to the temperature and liquid level fluctuations in the cabinet, and improves the system's adaptability to environmental changes. By ensuring that the coolant covers the entire server assembly, the heat dissipation effect is improved. At the same time, through the automated liquid level detection and alarm system, human intervention is reduced, and the system's automation level and operational safety are improved.

[0028] S2: Optimize the coolant inlet speed according to the flow sensor feedback and monitor the stable state of the liquid level in the server cabinet.

[0029] Furthermore, optimizing the coolant inlet speed according to the flow sensor feedback includes calculating the real-time inlet rate of the coolant in the server cabinet according to the flow sensor feedback data, automatically adjusting the coolant inlet flow rate, confirming the sufficient supply of coolant under high load conditions of the server, and reducing the liquid supply when the load is reduced. The system adjusts the coolant flow rate through the PID control algorithm, and adjusts the coolant inlet rate in real time according to different liquid level and temperature data. When the inlet rate exceeds the set range, the system automatically increases or decreases the coolant flow rate.

[0030] It should be noted that monitoring the stable state of the liquid level in the server cabinet includes real-time monitoring of the liquid level changes in the cabinet and recording the liquid level fluctuations every second after the coolant circulation system is started, analyzing the stability of the liquid level within a specified time, and determining whether the liquid level fluctuations meet the stability conditions. When the liquid level meets the set stability conditions, the server is turned on. If the liquid level fluctuations do not reach the stability standard within the set time, the system automatically increases the liquid inlet speed, re-detects the liquid level changes, and allows the server to start up only after confirming that the liquid level is stable.

[0031] It should also be noted that the steps of optimizing the coolant inlet speed according to the feedback from the flow sensor have significantly improved the operating efficiency and control accuracy of the immersion cooling system. By real-time monitoring of the flow sensor data, the coolant inlet flow rate is automatically adjusted to ensure sufficient supply of coolant under high server load conditions, while reducing the liquid supply when the load is reduced, thereby achieving optimal utilization of energy. The PID control algorithm is used to fine-tune the coolant flow rate, so that the system can dynamically adjust the liquid inlet rate according to the real-time data of the liquid level and temperature, which not only improves the response speed of the cooling system, but also ensures stable operation under different workloads. When the liquid inlet rate exceeds the set range, the system's automatic adjustment function effectively prevents the risk of insufficient cooling or over-cooling, thereby extending the service life of the server and reducing maintenance costs.

[0032] S3: Determines whether the coolant is leaking based on the liquid level growth rate and flow rate deviation. When the liquid level is insufficient, an alarm is triggered and the liquid level and cycle time are automatically adjusted.

[0033] Furthermore, judging whether the coolant is leaking based on the liquid level growth rate and flow rate deviation includes the system automatically monitoring the flow rate changes of the coolant in and out of the pipes, comparing the difference between the actual liquid inlet speed and the liquid outlet speed fed back by the flow rate sensor, and determining that the coolant may have leaked when the liquid level growth rate is lower than a predetermined range. After detecting that the liquid level growth rate is lower than a preset threshold, the system automatically issues an alarm and activates a redundant circulating liquid flow detection system when the coolant flow rate deviation exceeds the set threshold, to further confirm that the liquid level change is caused by a coolant leakage, and promptly notify maintenance personnel to handle the fault.

[0034] It should be noted that when the liquid level is insufficient, an alarm is triggered, and the liquid level and cycle time are automatically adjusted. This includes the system immediately triggering an alarm signal when it detects insufficient liquid level, automatically calculating the required liquid inlet rate, automatically adjusting the liquid inlet flow rate and cycle time according to actual conditions, and confirming that the coolant quickly recovers to the preset starting level. When the system detects that the coolant has returned to a safe level, it automatically reduces the liquid inlet speed, returns to normal cycle time, and re-tests the liquid level stability, confirming that the coolant fully covers the server components before lifting the alarm.

[0035] It should also be noted that judging whether the coolant is leaking based on the liquid level growth rate and flow rate deviation provides an efficient fault detection and early warning mechanism for the operation control method of the immersion server. By monitoring the flow rate changes of the coolant in the inlet and outlet pipes and comparing the difference between the actual liquid inlet speed and the liquid outlet speed, potential leakage can be quickly identified when the liquid level growth rate is lower than the predetermined range. The system's automatic alarm function and the activation of the redundant circulating liquid flow detection system improve the accuracy and timeliness of fault diagnosis, which not only reduces the downtime caused by coolant leakage, but also reduces the long-term operating cost of the system through timely maintenance notifications. By automatically adjusting the liquid level and circulation time, it ensures the rapid recovery of the system when a leak occurs, thereby improving the system's reliability and fault recovery capabilities.

[0036] Embodiment 2 is an embodiment of the present invention, which provides an immersion server operation control method. In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through economic benefit calculation and simulation experiments.

[0037] First, the system automatically detects the status of the liquid level sensor to ensure that it is in normal working condition. After reading the liquid level data, it determines whether the liquid level is higher than the preset start-up liquid level (50cm); if it is lower than this level, the system will send an alarm to the operator and terminate the startup process; when the liquid level is qualified, the system will activate the coolant circulation system and start the main circulation pump to ensure that the target flow rate (1.5m / s) can be reached within the set time (within 3 seconds); it is very important that the saturated liquid covers the entire server component, so it is detected whether the target flow rate is reached within the specified time. If it is not reached, the system will automatically enable the backup circulation pump and re-detect the flow rate; the system uses the flow rate sensor to feedback the value and optimize the flow rate of the incoming coolant in real time; if the load rises to 80%, the system will increase the inlet flow rate (1.8m / s), and when the load drops (20%), the flow rate is automatically adjusted to 1.2m / s; this adjustment process is implemented by the PID control algorithm to ensure that the flow can be fully supplied under all load conditions; after the coolant circulation system is running, the system records the liquid level fluctuations in the cabinet every second to determine the stability of the liquid level; if the liquid level fluctuations are not suppressed within the set standard, the system will automatically increase the liquid inlet rate, continue to observe and ensure that the server is allowed to start up only when the liquid level is in a stable state; the system will monitor the flow rate changes in the inlet and outlet pipes to determine whether there is a coolant leak; if there is a deviation between the inlet rate and the outlet rate fed back by the sensor, and the liquid level growth rate decreases, the system will start the backup detection system to confirm whether the coolant is leaking and notify the maintenance personnel in time; during operation, if the liquid level is lower than the safety threshold, the system will immediately trigger an alarm and automatically adjust the flow rate and circulation time to ensure that the coolant can quickly return to the preset starting liquid level; only when the liquid level returns to normal will the system release the alarm and reset to normal circulation.

[0038] Example 3, reference Figure 2 , as an embodiment of the present invention, provides an immersion server operation control system, including a liquid level detection activation module, a flow rate feedback optimization module, and a leakage judgment alarm module.

[0039] The liquid level detection activation module is used to determine whether the liquid level is higher than the preset start-up level, and activate the coolant circulation system to confirm the liquid flow; the flow rate feedback optimization module is used to optimize the coolant inlet speed according to the feedback from the flow rate sensor, and monitor the liquid level stability in the server cabinet; the leakage judgment alarm module is used to determine whether the coolant is leaking based on the liquid level growth rate and flow rate deviation, and trigger an alarm when the liquid level is insufficient, and automatically adjust the liquid level and circulation time.
