Description

Technical Field

[0001] This invention relates to the field of immersion cooling technology, specifically to an immersion server operation control method and system. Background Technology

[0002] With the rapid growth of modern information technology and big data processing demands, the scale and computing density of data centers are constantly increasing. Traditional air cooling methods are gradually revealing their limitations. In high-density computing environments, air cooling is not only inefficient but also struggles to cope with the high heat flux density generated by high-power processors and graphics cards. Immersion cooling, as a highly efficient thermal management technology, is gradually gaining attention. By completely immersing hardware devices in a coolant with excellent insulation and thermal conductivity, the heat generated by the devices can be directly and quickly removed. This not only improves cooling efficiency but also reduces 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, driving innovation in energy conservation, emission reduction, and improved computing performance.

[0003] However, immersion cooling technology still has many shortcomings in thermal management. Most immersion cooling systems lack sophisticated management tools for liquid level monitoring. The sensor technology currently used often cannot accurately capture subtle changes in liquid level, especially during high-load operation. Liquid level fluctuations may lead to untimely coolant supply, increasing the risk of thermal runaway. Insufficient control of liquid level fluctuations directly affects the efficiency and safety of the cooling system. 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 load, resulting in limited energy efficiency and resource waste. When the system detects overload or high temperature, traditional solutions cannot respond quickly and require manual readjustment, 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 have mature automatic detection and response mechanisms. The system cannot quickly locate the problem and take effective measures when the liquid level increases or the 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 problem solved by this invention is that existing immersion cooling technologies suffer from inaccurate liquid level control, insufficient optimization of coolant flow rate, and untimely detection of coolant leaks, as well as the problem of how to achieve a more efficient and reliable cooling control system through intelligent monitoring and automatic adjustment mechanisms.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an immersion server operation control method, including determining whether the liquid level is higher than the preset start liquid level, activating the coolant circulation system to confirm liquid flow; optimizing the coolant inlet speed based on feedback from the flow rate sensor, and monitoring the stability of the liquid level in the server rack; determining whether the coolant is leaking based on the liquid level increase 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 embodiment of the immersion server operation control method of the present invention, the step of determining whether the liquid level is higher than the preset start-up liquid level includes automatically detecting the status of the liquid level sensor, collecting liquid level data in the server rack after receiving the power-on command, confirming whether the liquid level is higher than the preset start-up liquid level after the liquid level detection is completed, and if the liquid level is lower than the preset liquid level, the system sends an alarm prompt 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 components. The system dynamically adjusts the preset start-up 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 rack during detection, and triggering an emergency shutdown when the preset threshold is exceeded.

[0008] As a preferred embodiment of the immersion server operation control method of the present invention, the activation of the coolant circulation system to confirm liquid flow includes automatically detecting the current state of the coolant circulation system, immediately starting the circulation pump after the system detects that the liquid level meets the requirements, confirming that the system reaches the preset flow rate within a set time, and when the circulation pump fails to reach the target flow rate within a specified time, 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 the liquid level fluctuation is detected to exceed 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 embodiment of the immersion server operation control method described in this invention, the step of optimizing the coolant inlet speed based on flow rate sensor feedback includes calculating the real-time inlet rate of the server rack coolant based on the flow rate sensor feedback data, automatically adjusting the coolant inlet flow rate, ensuring sufficient coolant supply under high server load conditions, and reducing the liquid supply when the load decreases. The system adjusts the coolant flow rate through a PID control algorithm, adjusting 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 embodiment of the immersion server operation control method of the present invention, the monitoring of the liquid level stability in the server rack includes: after the coolant circulation system is started, monitoring the liquid level change in the rack in real time and recording the liquid level fluctuation every second, analyzing the stability of the liquid level within a specified time, determining whether the liquid level fluctuation meets the stability condition, and starting the server when the liquid level meets the set stability condition. If the liquid level fluctuation does not reach the stability standard within the set time, the system automatically increases the liquid inlet speed, re-detects the liquid level change, and allows the server to start only after confirming that the liquid level is stable.

[0011] As a preferred embodiment of the immersion server operation control method described in this invention, the step of determining whether coolant is leaking based on liquid level increase rate and flow rate deviation includes the system automatically monitoring the flow rate changes of coolant in the inlet and outlet pipes, comparing the difference between the actual inlet and outlet flow rates fed back by the flow rate sensor, and determining that coolant may be leaking when the liquid level increase rate is lower than a predetermined range. After detecting that the liquid level increase rate is lower than a preset threshold, the system automatically issues an alarm, and when the coolant flow rate deviation exceeds a set threshold, a redundant circulating fluid flow detection system is activated to further confirm that the liquid level change is caused by coolant leakage, and maintenance personnel are promptly notified to handle the fault.

[0012] As a preferred embodiment of the immersion server operation control method of the present invention, the step of triggering an alarm when the liquid level is insufficient and automatically adjusting the liquid level and circulation time 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 circulation time according to the actual situation, confirming that the coolant is quickly restored to the preset starting liquid level, and when the system detects that the coolant has been restored to a safe liquid level, automatically reducing the liquid inlet rate, returning to the normal circulation time, and re-detecting the liquid level stability. After confirming that the coolant fully covers the server components, the alarm is lifted.

[0013] Another objective of this invention is to provide an immersion server operation control system that can optimize the coolant inlet speed based on feedback from a flow rate sensor and monitor the stability of the coolant level within the server rack, thus solving the problems of lack of flexibility and real-time performance in current immersion cooling technologies regarding coolant flow rate control.

[0014] As a preferred embodiment of the immersion server operation control system described in this 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 start liquid level, activate the coolant circulation system to confirm liquid flow; the flow rate feedback optimization module is used to optimize the coolant inlet speed based on the feedback from the flow rate sensor and monitor the stability of the liquid level in the server rack; the leakage judgment alarm module is used to determine whether the coolant is leaking based on the liquid level increase rate and flow rate deviation, 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, the memory storing a computer program, and the processor executing the computer program as a step in implementing an immersive server operation control method.

[0017] A computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the steps of an immersion server operation control method.

[0018] The beneficial effects of this invention: The immersion server operation control method provided by this invention determines whether the liquid level is higher than the preset start-up liquid level, activates the coolant circulation system to confirm liquid flow, and achieves strict control over the start-up conditions of the cooling system. This ensures that the coolant reaches the necessary coverage level before the server starts, effectively preventing equipment overheating or damage due to insufficient coolant. This not only improves system safety but also reduces the risk of manual intervention, ensuring safe and stable operation of the equipment under conditions that meet cooling requirements. The coolant inlet speed is optimized based on flow rate sensor feedback, and the stable liquid level in the server rack is monitored, achieving dynamic coolant supply. When the server load is high, the system can guarantee sufficient coolant delivery, effectively preventing performance degradation or hardware damage caused by overheating. When the load decreases, the system automatically reduces the liquid supply, thereby saving energy. This flexible flow rate optimization mechanism not only improves cooling efficiency but also reduces operating costs. By monitoring the liquid level changes in the rack in real time, the system... This invention ensures stable coolant levels, reduces equipment failures caused by coolant level fluctuations, and guarantees the safe and stable operation of servers. It determines coolant leakage based on coolant level increase and flow rate deviation, triggering an alarm when the coolant level is insufficient and automatically adjusting the coolant level and circulation time. By monitoring flow rate changes in real time and comparing the difference between the actual inflow and outflow rates, early leak detection is achieved. When the system detects that the coolant level increase is below a predetermined range, it immediately issues an alarm and activates redundant flow rate sensors to further confirm the problem. This rapid response capability effectively improves system safety and reduces potential risks caused by coolant leaks. In the event of insufficient coolant level, the system automatically adjusts the inflow flow rate and circulation time to quickly restore the coolant level to a safe standard. This self-adjusting capability ensures that the system can respond and repair quickly in the event of abnormalities, thereby reducing equipment failure rates and improving the overall stability and reliability of the data center. This invention achieves better results in terms of safety, cooling efficiency, and fault response capabilities. Attached Figure Description

[0019] To more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the following description of the embodiments will be briefly introduced. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0020] Figure 1 The first embodiment of the present invention provides an overall flowchart of an immersion server operation control method.

[0021] Figure 2 The following is an overall flowchart of an immersion server operation control system provided in the third embodiment of the present invention. Detailed Implementation

[0022] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0023] Example 1, referring to Figure 1 As an embodiment of the present invention, an immersion server operation control method is provided, comprising:

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

[0025] Furthermore, determining whether the liquid level is higher than the preset start-up liquid level includes automatically detecting the status of the liquid level sensor. After receiving the power-on command, the system collects liquid level data in the server rack. After the liquid level detection is completed, it confirms whether the liquid level is higher than the preset start-up liquid level. 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 components. The system dynamically adjusts the preset start-up liquid level according to the server's installation height and optimizes the sensor accuracy under different load conditions. It confirms that the sensor adapts to temperature and liquid level fluctuations in the rack 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 status of the coolant circulation system. Once the system detects that the liquid level meets the requirements, it immediately starts the circulation pump to confirm that the system reaches the preset flow rate within a set time. If the circulation pump fails to reach the target flow rate within the specified time, 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 powered on. Multiple detection modes are set in the liquid level and flow rate detection. Redundant flow rate sensors are used to confirm whether the actual flow rate is consistent with the target flow rate. If the liquid level fluctuation is detected to exceed 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 determining whether the liquid level is higher than the preset start-up liquid level, precise control of the start-up conditions of the immersion server cooling system is achieved. By automatically detecting the status of the liquid level sensor and immediately collecting liquid level data after receiving the power-on command, the system ensures that it only starts when the liquid level meets the safety conditions, avoiding low cooling efficiency and potential equipment damage risks caused by insufficient liquid level. The system dynamically adjusts the preset start-up liquid level according to the server's installation height and optimizes sensor accuracy to adapt to temperature and liquid level fluctuations within the rack, improving the system's adaptability to environmental changes. By ensuring that the coolant covers the entire server components, the heat dissipation effect is improved. At the same time, through the automated liquid level detection and alarm system, human intervention is reduced, improving the system's automation level and operational safety.

[0028] S2: Optimize the coolant inlet speed based on feedback from the flow rate sensor and monitor the stability of the coolant level in the server rack.

[0029] Furthermore, the system optimizes the coolant inlet speed based on flow rate sensor feedback. This includes calculating the real-time coolant inlet rate of the server rack based on the flow rate sensor feedback data, automatically adjusting the coolant inlet flow rate, ensuring sufficient coolant supply under high server load conditions, and reducing the liquid supply when the load decreases. The system adjusts the coolant flow rate through a PID control algorithm, adjusting 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 stability of the liquid level in the server rack includes real-time monitoring of the liquid level changes in the rack and recording the liquid level fluctuations every second after the coolant circulation system is started. The stability of the liquid level within a specified time is analyzed to determine 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 be turned on only after confirming that the liquid level is stable.

[0031] It should also be noted that the step of optimizing the coolant inlet speed based on flow rate sensor feedback significantly improves the operating efficiency and control accuracy of the immersion cooling system. By monitoring flow rate sensor data in real time, the system automatically adjusts the coolant inlet flow rate, ensuring sufficient coolant supply under high server load conditions and reducing liquid supply when the load decreases, thereby achieving optimal energy utilization. The use of a PID control algorithm for fine adjustment of the coolant flow rate allows the system to dynamically adjust the inlet rate based on real-time data of liquid level and temperature. This not only improves the response speed of the cooling system but also ensures stable operation under different workloads. When the inlet rate exceeds the set range, the system's automatic adjustment function effectively prevents the risk of insufficient or excessive cooling, thereby extending the service life of the server and reducing maintenance costs.

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

[0033] Furthermore, the system determines whether coolant is leaking based on the increase in liquid level and the deviation in flow rate. This includes automatically monitoring the changes in the flow rate of coolant in the inlet and outlet pipes, comparing the difference between the actual inlet and outlet flow rates reported by the flow rate sensor, and determining that coolant leakage may occur when the increase in liquid level is below a predetermined range. After detecting that the increase in liquid level is below a preset threshold, the system automatically issues an alarm. When the deviation in coolant flow rate exceeds a set threshold, a redundant circulating fluid flow detection system is activated to further confirm that the liquid level change is caused by coolant leakage and to 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 circulation 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, and automatically adjusting the liquid inlet flow rate and circulation time according to the actual situation to ensure that the coolant is quickly restored to the preset starting liquid level. When the system detects that the coolant has been restored to a safe liquid level, it automatically reduces the liquid inlet rate, returns to the normal circulation time, and re-detects the liquid level stability. The alarm is deactivated after confirming that the coolant fully covers the server components.

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

[0036] Example 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 experiment.

[0037] First, the system automatically detects the status of the liquid level sensor to ensure 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 start-up 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) is reached within the set time (3 seconds). It is crucial for the saturated liquid to cover the entire server components, so it is necessary to detect whether the target flow rate is reached within the specified time. If it is not reached, the system will automatically activate the backup circulation pump and re-detect the flow rate. The system optimizes the flow rate of the coolant entering the system in real time through the feedback value of the flow rate sensor. If the load rises to 80%, the system will increase the inlet flow rate (1.8m / s), and when the load decreases (20%), the flow rate will automatically adjust to 1.2m / s. This adjustment process is implemented by a PID control algorithm. To ensure sufficient flow under various load conditions, the system records the coolant level fluctuations within the cabinet every second after the coolant circulation system begins operation, assessing its stability. If the fluctuations are not suppressed within the set standard, the system automatically increases the inlet rate, continuously monitoring and ensuring the server is powered on only when the level is stable. The system monitors the flow rate changes in the inlet and outlet pipes to determine if there is a coolant leak. If there is a discrepancy between the inlet and outlet rates reported by the sensors, and the coolant level increase rate decreases, the system activates a backup detection system to confirm coolant leakage and promptly notify maintenance personnel. During operation, if the coolant level falls below a safety threshold, the system immediately triggers an alarm and automatically adjusts the flow rate and circulation time to ensure the coolant can quickly recover to the preset starting level. Only when the coolant level returns to normal will the system deactivate the alarm and reset to normal circulation.

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