Description

Technical Field

[0001] This invention relates to the field of server heat dissipation and temperature control technology, and in particular to a method and system for autonomous temperature adjustment of an immersion liquid-cooled server. Background Technology

[0002] Currently, the cooling methods for high-performance edge servers still mainly rely on air cooling or simple liquid cooling-assisted solutions, which are significantly insufficient under conditions of high heat flux density, continuous high load, and non-standard data center deployment. For example, for edge servers equipped with high-heat-generating components such as CPUs and GPUs, traditional air cooling mainly relies on airflow organization and high-speed fans to remove heat. The heat dissipation path is long, and the heat exchange efficiency is greatly affected by the environment. When servers are deployed in high-temperature, dusty, space-constrained, or unequipped locations, problems such as localized heat accumulation, untimely cooling of hot spots, and excessive noise from the entire machine can easily occur. While some existing liquid cooling solutions can improve heat exchange capacity by utilizing the cooling medium, they usually still rely on external cooling infrastructure, complex piping layouts, or fixed control strategies, resulting in insufficient structural integration, complex maintenance, high requirements for sealing reliability, and insufficient response to real-time changes in thermal load.

[0003] Furthermore, most existing temperature control methods perform single start / stop control of pumps or fans based on preset temperature thresholds, lacking a coordinated adjustment process based on the correlation between device temperature, coolant temperature, and air temperature. This makes it difficult to perform tiered adjustments based on the heat transfer state between heat-generating devices such as CPUs and GPUs and the coolant, as well as the heat dissipation state between the coolant and the external air. Consequently, when server workloads fluctuate rapidly, heat levels rise instantaneously, or the server operates under sustained high loads, existing technologies cannot fully meet the requirements for low noise, low maintenance, rapid heat dissipation, autonomous temperature control, and long-term stable operation in edge deployment scenarios.

[0004] Therefore, there is an urgent need for a method to autonomously regulate the temperature of internal heat-generating components, coolant temperature, and external air heat exchange status of immersion liquid-cooled servers in non-standard computer rooms with high temperatures and dust, limited space, and a lack of professional operation and maintenance support, so as to improve the server's heat dissipation efficiency, operational stability, and environmental adaptability. Summary of the Invention

[0005] To address the aforementioned technical shortcomings, the purpose of this invention is to propose a method for autonomous temperature regulation of immersion liquid-cooled servers.

Step S403: According to the current operating speed of the crossflow fan, air is delivered along the extension direction of the heat dissipation fins on the upper cover to enhance the heat dissipation process of the liquid coolant to the air side through the heat dissipation fins on the upper cover, and the air-liquid synergistic heat dissipation unit is output.

[0013] Preferably, step S50, which involves performing alarm protection and recovery control processing based on the gas-liquid coordinated heat dissipation set to obtain a temperature control execution result set, includes: Step S501: Determine if the system is overheating based on the coolant temperature, CPU temperature, and GPU temperature corresponding to the gas-liquid synergistic heat dissipation system.

[0017] The beneficial effects of this invention are as follows: By constructing a first temperature difference between the CPU, GPU and the liquid coolant and a second temperature difference between the liquid coolant and the air, and using the temperature difference as the basis for determining the adjustment of the liquid cooling pump and the crossflow fan, this invention achieves the linkage control of the multi-stage heat transfer path of "device-liquid-air", transforming the heat dissipation adjustment process from a fixed strategy to an adaptive adjustment based on real-time temperature difference, effectively reducing local heat accumulation and improving heat dissipation efficiency and temperature control accuracy.

[0018] This invention sets alarm judgment and self-protection trigger conditions, and combines downgrading and shutdown recovery control after temperature drop, so that the liquid cooling pump and crossflow fan can operate in stages and be shut down as needed while meeting heat dissipation requirements.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1: As Figure 1 The diagram shown is a flowchart of the first embodiment of the immersion liquid-cooled server temperature autonomous adjustment method of the present invention, which presents the first embodiment of the immersion liquid-cooled server temperature autonomous adjustment method of the present invention.

[0025] In the first embodiment, the method for autonomous temperature regulation of the immersion liquid-cooled server includes: Step S10: Obtain server structure parameters, sensor configuration parameters, and temperature control preset parameters, and initialize the server structure parameters, sensor configuration parameters, and temperature control preset parameters to obtain a temperature control configuration set; It should be noted that step S10 serves to provide a unified initial configuration basis for subsequent temperature acquisition, temperature difference calculation, liquid cooling pump adjustment, crossflow fan adjustment, and alarm protection control. Specifically, the server structure parameters characterize the physical layout of the immersion liquid-cooled server, the sensor configuration parameters characterize the temperature acquisition object and acquisition channel, and the temperature control preset parameters characterize the threshold, gear, and sampling rules used in subsequent adjustment processes. By initializing these parameters, the dispersed hardware structure information, sensor information, and control information can be organized into a temperature control configuration set that can be directly called upon in subsequent steps.

[0026] It is understood that the server structural parameters may include at least the sealed liquid cooling cavity structural parameters, liquid cooling pump installation position parameters, liquid cooling pump outlet orientation parameters, CPU and GPU installation position parameters, hard disk assembly layout parameters, and crossflow fan installation position parameters; the sensor configuration parameters may include at least the liquid temperature sensor location parameters, air temperature sensor location parameters, CPU internal temperature reading interface parameters, and GPU internal temperature reading interface parameters; the temperature control preset parameters may include at least the first temperature difference compensation threshold, the second temperature difference compensation threshold, the liquid coolant temperature threshold, the liquid coolant alarm temperature threshold, the device alarm temperature threshold, the device self-protection temperature threshold, the liquid cooling pump speed parameters at each speed setting, the crossflow fan speed parameters at each speed setting, the sampling period parameters, and the number of consecutive judgments parameters.

[0027] It should be understood that the initialization process in step S10 is not limited to simply reading parameters. It can also include format verification, range verification, default value completion, sensor channel binding, control gear mapping, and initial state registering of parameters. For example, the liquid cooling pump state can be initialized to the off state, the crossflow fan state can be initialized to the off state, the historical temperature buffer can be initialized to empty, and the continuous judgment counter can be initialized to zero, thereby ensuring that all control logics are executed from a unified starting point after the system is powered on.

[0028] For example, in one specific embodiment, the server reads the preset temperature control parameters in the BIOS or control board during the boot-up phase, sets the first temperature difference compensation threshold to 25°C, the second temperature difference compensation threshold to 15°C~30°C, the liquid coolant temperature threshold to 35°C, and the liquid coolant alarm temperature threshold to 55°C. At the same time, it sets the low speed parameters of the liquid cooling pump, the high speed parameters of the liquid cooling pump, the low speed parameters of the crossflow fan, the high speed parameters of the crossflow fan, and a sampling period of 10 minutes, thereby generating the temperature control configuration set.

[0029] Step S20: Collect CPU temperature, GPU temperature, coolant temperature and air temperature based on the temperature control configuration set, and perform temperature difference feature construction processing to obtain a temperature feature set; It should be noted that the purpose of step S20 is to synchronously collect and correlate multi-source temperature data directly related to the heat dissipation process based on the temperature control configuration set obtained in step S10, and further construct temperature difference features that can be used for subsequent control. The temperature difference feature set is not a simple set of raw temperatures, but is composed of the relationship between device temperature and coolant temperature, the relationship between coolant temperature and air temperature, and the corresponding historical change relationships.

[0030] It is understood that, in this embodiment, the temperature difference feature construction process may at least include: acquiring the CPU temperature at the k-th sampling time. GPU temperature Liquid coolant temperature and air temperature ; Calculate the first temperature difference between the CPU, GPU, and coolant. ; Calculate the second temperature difference between the coolant and the air. The first and second temperature differences at multiple consecutive sampling times are then time-series organized to form the temperature feature set. The first temperature difference characterizes the thermal coupling state after heat transfer from the heating device to the coolant, while the second temperature difference characterizes the heat exchange state when the coolant dissipates heat to the external air.

[0031] It should be understood that the temperature difference feature construction process in step S20 can use either the instantaneous temperature difference at the current sampling moment or the statistical temperature difference formed by multiple consecutive sampling periods, such as the moving average temperature difference, the continuous count temperature difference, or the interval change trend temperature difference. The purpose of this setting is to avoid false triggering of the control results due to single sampling fluctuations, thereby improving the stability of the subsequent liquid cooling pump and crossflow fan adjustment process.

[0032] For example, in one specific embodiment, the first temperature difference at the k-th sampling time can be calculated according to the following formula:

[0033] The second temperature difference at the k-th sampling time can be calculated using the following formula:

[0034] in, This represents the average temperature difference between the CPU, GPU, and coolant at the k-th sampling point. This represents the temperature difference between the coolant and the air at the k-th sampling point. Furthermore, the average of the first temperature differences from N consecutive samplings can be calculated for use in subsequent coolant pump adjustments.

[0035] Step S30: Perform liquid cooling pump range adjustment processing based on the temperature feature set to obtain the liquid circulation control set; It should be noted that step S30 is used to control the start / stop status and operating level of the liquid cooling pump based on the temperature feature set obtained in step S20, especially the first temperature difference and its changes. This changes the flow intensity of the coolant around the CPU, GPU, power module, and hard disk components, thereby improving the heat-carrying capacity of the heat-generating areas. The liquid circulation control set is used to characterize the control results of the liquid cooling pump and the corresponding liquid circulation state within the current control cycle.

[0036] It is understood that the liquid cooling pump range adjustment process can include at least the following control logic: when the comparison result between the first temperature difference and the first temperature difference compensation threshold indicates that the liquid coolant needs to enhance flow and the liquid coolant temperature reaches the preset trigger condition, if the liquid cooling pump is currently in the off state, then the liquid cooling pump is controlled to enter the low-range operation state; if the liquid cooling pump is already in the low-range operation state, then the liquid cooling pump is controlled to enter the high-range operation state; if the liquid cooling pump is already in the high-range operation state, then the high-range operation state is maintained.

[0037] It should be understood that the "gradient adjustment" in step S30 can be triggered either based on a single sampling result or based on multiple consecutive sampling results. Preferably, the N consecutive temperature difference data obtained in step S20 can be used as the judgment basis to avoid frequent gear switching of the liquid cooling pump due to instantaneous load changes or sampling noise. In addition, the liquid circulation control set can include not only the target gear information of the liquid cooling pump, but also the execution time, execution number, liquid cooling liquid circulation enhancement state, and control feedback state. For example, when N consecutive samplings meet the condition that the first temperature difference is not greater than the first temperature difference compensation threshold and the liquid cooling liquid temperature is not lower than 35°C, if the liquid cooling pump is in the off state, a low-gear start command is sent to the liquid cooling pump; if the liquid cooling pump is already in the low-gear operation state, a high-gear operation command is sent to the liquid cooling pump; if the liquid cooling pump is already in the high-gear operation state, the current high-gear operation state is maintained. In this way, the system can form the liquid circulation control set according to the actual heat transfer state between the device and the liquid cooling liquid.

[0038] For example, such as Figure 2 As shown, in the internal structure of the immersion liquid-cooled server, the liquid cooling pump is located on one side of the sealed liquid cooling cavity. Its outlet faces the heat-generating gap area formed between the CPU, GPU, power module, and L-shaped hard drive rack, and the outlet position is lower than the installation height of the CPU, GPU, and power module, so that the liquid coolant preferentially flows through the heat-intensive area under the drive of the liquid cooling pump. The motherboard is mounted inside the cavity via support columns. The L-shaped hard drive rack is arranged in a staggered manner, forming a through-flow channel between the upper and lower hard drives, thus creating a circulating flow path from the bottom to the top cover when the liquid cooling pump is working. Under this structural condition, when the first temperature difference obtained in step S20, which represents the temperature difference between the CPU, GPU, and liquid coolant, decreases to within the first temperature difference compensation threshold range, and the liquid coolant temperature reaches the preset trigger temperature, it indicates that the heat exchange capacity of the liquid around the heat-generating devices has approached saturation. At this time, it is necessary to enhance the liquid flow to improve the heat carrying capacity.

[0039] Specifically, when the liquid cooling pump is in the off state, the control module sends a low-speed start command to the liquid cooling pump, causing the liquid coolant to flow along the outlet direction to the gap area between the CPU, GPU, and power module; when the liquid cooling pump is already in the low-speed operation state, and the results of multiple consecutive samplings still meet the condition that the first temperature difference is not greater than the first temperature difference compensation threshold, a high-speed operation command is further sent to the liquid cooling pump to increase the flow rate of the liquid coolant, thereby accelerating the transfer of heat to the chassis cover and heat sink fin area; when the liquid cooling pump is already in the high-speed operation state, the current operation level is maintained.

[0040] Step S40: Perform cross-flow fan-assisted heat dissipation based on the liquid circulation control set to obtain a gas-liquid assisted heat dissipation set; It should be noted that step S40, based on the enhanced liquid circulation achieved in step S30, further enhances the heat release of the liquid coolant from the chassis cover and heat exchange fins to the air side by using a crossflow fan to deliver air along the direction of the heat dissipation fins. This achieves coordinated heat dissipation between the liquid circulation path and the air heat exchange path. The gas-liquid coordinated heat dissipation set is used to characterize the heat dissipation state formed by the combined action of the liquid pump and the crossflow fan within the same control cycle.

[0041] It is understandable that the crossflow fan-assisted heat dissipation process in step S40 can be jointly executed based on the second temperature difference established in step S20 and the liquid circulation control state formed in step S30. Specifically, when the second temperature difference reaches the second temperature difference compensation threshold, it can be considered that there is a significant heat exchange drive demand from the liquid coolant to the air side; when the second temperature difference does not reach the compensation threshold but the liquid coolant temperature has reached the preset heat dissipation trigger condition, the crossflow fan can also be activated to enhance the external heat dissipation capacity in advance.

[0042] It should be understood that the coordinated heat dissipation process in step S40 is not limited to simply controlling the fan to start and stop. It may also include adjusting the operation of the crossflow fan to low speed, high speed, reduced speed, or stop operation based on the liquid coolant temperature, the second temperature difference, and their changing trends. Preferably, after the liquid cooling pump has been started and enhanced liquid circulation has been achieved, the decision to further start the crossflow fan can be made based on the second temperature difference, thereby forming a seamless heat transfer link between "internal liquid heating" and "external air heat release".

[0043] For example, in one specific embodiment, when the second temperature difference between the liquid coolant and the air temperature reaches the second temperature difference compensation threshold and the crossflow fan is in the off state, the crossflow fan is controlled to enter the low-speed operation state; when multiple consecutive samplings show that the second temperature difference is continuously higher than the second temperature difference compensation threshold, or the liquid coolant temperature is greater than 45°C, the crossflow fan is controlled to enter the high-speed operation state, thereby generating the gas-liquid synergistic heat dissipation set.

[0044] Step S50: Perform alarm protection and recovery control processing based on the gas-liquid coordinated heat dissipation set to obtain the temperature control execution result set.

[0045] It should be noted that step S50 serves to make a final safety determination on the server operating temperature based on the gas-liquid synergistic heat dissipation state already established in step S40, and outputs corresponding control results when alarm conditions, self-protection conditions, or recovery conditions are met. The temperature control execution result set is used to uniformly represent the alarm state, self-protection state, liquid cooling pump state, crossflow fan state, and recovery state within the current control cycle.

[0046] It is understood that step S50 may include at least the following processing: determining overheating based on the coolant temperature, CPU temperature, and GPU temperature; outputting an alarm result when the coolant temperature reaches the coolant alarm temperature threshold and the CPU temperature or GPU temperature reaches the device alarm temperature threshold; outputting a self-protection result when the CPU temperature or GPU temperature reaches the device self-protection temperature threshold and the first temperature difference is not greater than the first temperature difference compensation threshold; and controlling the liquid cooling pump and crossflow fan to perform downshift operation or stop operation when the coolant temperature, the first temperature difference, and the second temperature difference fall back to the corresponding recovery condition range, and summarizing the control results to output a temperature control execution result set.

[0047] It should be understood that the recovery control process in step S50 can be configured in conjunction with the aforementioned alarm protection process. That is, protection actions are performed when the temperature continues to rise, and downshifting or shutdown actions are performed after the temperature falls, in order to avoid the additional energy consumption and mechanical wear caused by the liquid cooling pump and crossflow fan maintaining high-speed operation for a long time. In addition, the temperature control execution result set may also include historical result cache, timestamp information, execution source identifier, and control result reporting information for subsequent maintenance or log tracking.

[0048] For example, in one specific embodiment, when the coolant temperature reaches 55°C and the CPU or GPU temperature reaches the device alarm temperature threshold, the system outputs a server overheat alarm; when the CPU or GPU temperature continues to rise to the device self-protection temperature threshold, and the first temperature difference is not greater than the first temperature difference compensation threshold, the system outputs a self-protection result, suspends user threads running on the server, or puts the server into hibernation mode; in subsequent continuous sampling, when the coolant temperature is below 45°C, the second temperature difference is below the second temperature difference compensation threshold, and the first temperature difference falls back to the recovery range, the system controls the crossflow fan and the coolant pump to sequentially perform downshifting or stop operation, and summarizes the alarm result, self-protection result, coolant pump adjustment result, and crossflow fan adjustment result and outputs them as the temperature control execution result set.
