[0004] However, in the above heat dissipation control method, when the fan controller device is running in a harsh environment, the fan air inlet is easily contaminated by foreign matter such as dust, resulting in the actual air intake volume being lower than the preset air intake volume even when the fan is running at a high speed (i.e., high power), thereby affecting the actual cooling effect and wasting electricity. In addition, since the server load is constantly changing, the temperature is also constantly changing with the load, and the fan is constantly in an adjustment state.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings 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.

[0021] Figure 1 The figure is a flow chart of the server heat dissipation control method provided by the present invention. The method is performed by a fan control chip and includes: S11, obtaining the temperature of the power consumption device, the wind pressure and the system load; wherein the wind pressure is obtained based on the detection between the air inlet of the wind shield of the server and the fan; S12, determining a heat dissipation method according to the power consumption device temperature, wind pressure and system load in combination with a preset heat dissipation control rule; wherein the preset heat dissipation control rule is used to limit the heat dissipation method corresponding to the power consumption device temperature, wind pressure and system load; S13, controlling the server to dissipate heat according to the heat dissipation method.

[0022] It should be noted that the step numbers "S1N" in this manual do not represent the order of the server heat dissipation control method. Figure 2-Figure 4 The server heat dissipation control method of the present invention is described.

[0023] S11, obtaining the temperature of the power consumption device, the wind pressure and the system load; wherein the wind pressure is obtained based on the detection between the air inlet of the wind shield of the server and the fan.

[0024] In this embodiment, reference Figure 2 , obtain the power consumption device temperature, wind pressure and system load, including: receiving the power consumption device temperature sent by the temperature sensor; receiving the wind pressure sent by the wind pressure sensor, the wind pressure sensor is arranged between the wind shield air inlet and the fan; receiving the system load sent by the server load detection device.

[0025] It should be noted that the temperature sensor can be configured according to the power consumption devices actually configured in the server to collect the temperature of the corresponding power consumption devices; the server load detection device can be determined according to the actual configuration of the server, such as the central processing unit (CPU), redundant array of inexpensive disks (RAID), etc., which is not further limited here.

[0026] In addition, by arranging the wind pressure sensor between the wind shield air inlet and the fan, it is convenient to determine whether the wind shield is affected by foreign matter by judging the abnormal wind pressure, thereby avoiding affecting the heat dissipation effect of the fan.

[0027] It should be noted that the power consumption device temperature, wind pressure and system load are collected based on the same collection frequency, so as to determine the heat dissipation method based on the power consumption device temperature, wind pressure and system load at the same time. In addition, the collection frequency can be set according to the actual required temperature control accuracy. When the required control accuracy is higher, the collection frequency is also higher. It can be set according to the actual design requirements and is not further limited here.

[0028] S12, determining a heat dissipation method according to the power consumption device temperature, wind pressure and system load in combination with preset heat dissipation control rules; wherein the preset heat dissipation control rules are used to limit the heat dissipation method corresponding to the power consumption device temperature, wind pressure and system load.

[0029] In this embodiment, the heat dissipation method includes a blocking processing strategy, a load adjustment strategy and a fan adjustment strategy. Figure 3 , according to the temperature of the power-consuming device, the wind pressure and the system load, combined with the preset heat dissipation control rules, determine the heat dissipation method, including: based on the wind pressure exceeding the preset pressure range, determine whether the temperature of the power-consuming device meets the preset temperature range, and determine the degree of blockage of the windshield according to the comparison result of the temperature of the power-consuming device and the preset temperature range, so as to determine the blockage processing strategy according to the blockage degree of the windshield; based on the upper limit temperature of the power-consuming device temperature exceeding the preset temperature range, if the system load exceeds the preset load range, determine the load adjustment strategy to reduce the load, otherwise, determine the load adjustment strategy to not adjust the load; based on the power-consuming device temperature meeting the preset temperature range, if the system load exceeds the preset load range, determine the fan adjustment strategy to increase the fan speed, otherwise, determine the fan adjustment strategy to not adjust the fan speed; based on the power-consuming device temperature being lower than the lower limit temperature of the preset temperature range, if the system load exceeds the preset load range, determine the fan adjustment strategy to increase the fan speed, otherwise, determine the fan adjustment strategy to reduce the fan speed.

[0030] It should be added that when the wind pressure exceeds the preset pressure range, the temperature of the power-consuming device exceeds the upper limit of the preset temperature range. At this time, the fan heat dissipation is insufficient. If the system load exceeds the preset load range, the server system temperature will further increase. Therefore, it is necessary to reduce the equipment load to prevent various faults and errors, such as freezes and data loss, to ensure that the server system can run stably, provide users with reliable services, and extend the service life of the server hardware.

[0031] In addition, based on the fact that the temperature of the power consumption device is within the preset temperature range, if the system load exceeds the preset load range, the server system temperature will further increase. At this time, since the temperature of the power consumption device is within the preset temperature range, it means that the fan can meet the heat dissipation requirements. Therefore, the fan speed can be increased in advance to effectively prevent the server system temperature from further increasing, so that the equipment can quickly enter a balance and avoid system failures and data losses caused by excessive temperature. At the same time, the response speed and adaptability of the server are improved, so that the server can maintain a good heat dissipation state under different load conditions, providing a strong guarantee for the efficient operation of the server.

[0032] In addition, based on the fact that the temperature of the power-consuming device is lower than the lower limit of the preset temperature range, if the system load exceeds the preset load range, at this time, the fan can meet the heat dissipation requirements, and the fan speed can be increased in advance to effectively prevent the server system temperature from further increasing, so that the equipment can quickly enter balance; if the system load meets the preset load range, since the temperature of the power-consuming device is lower than the lower limit of the preset temperature range, the fan speed can be reduced to save energy.

[0033] It is worth noting that the judgment logic of whether the wind pressure exceeds the preset pressure range can be determined by comprehensive evaluation based on the machine's heat dissipation design, heat dissipation design redundancy, maximum thermal power consumption, and the maximum temperature that the equipment can withstand. The preset pressure range can be set according to the actual judgment logic, equipment, and use environment involved, and is not further limited here. In addition, when using multiple fans and heat dissipation channels, even if a part of them has problems, the other parts can maintain the wind pressure to a certain extent, and the relatively stable environmental conditions of the server also make the wind pressure less susceptible to external interference, so the wind pressure will not be lower than the lower limit of the preset pressure range.

[0034] In addition, the judgment logic of whether the temperature of the power consumption device meets the preset temperature range and whether the system load exceeds the preset load range can refer to the judgment logic of the above wind pressure. The preset temperature range and the preset load range can refer to the above preset pressure range configuration, which will not be repeated here. In addition, servers are usually deployed to meet specific business needs and have the ability to automatically adjust the load. In order to cope with sudden load peaks and ensure system reliability, certain resources are usually reserved, so the system load will not be lower than the lower limit of the preset load range.

[0035] Furthermore, based on the comparison result between the power consumption device temperature and the preset temperature range, the blockage degree of the windshield is determined, and based on the blockage degree of the windshield, the blockage handling strategy is determined, including: if the power consumption device temperature exceeds the upper limit temperature of the preset temperature range, it is determined that the blockage degree of the windshield is serious, and the blockage handling strategy is determined to be cleaning the windshield; if the power consumption device temperature meets the preset temperature range, or the power consumption device temperature is lower than the lower limit temperature of the preset temperature range, it is determined that the blockage degree of the windshield is slight, and the blockage handling strategy is determined to be cleaning or not cleaning the windshield.

[0036] It should be noted that when the wind pressure exceeds the preset pressure range, if the temperature of the power consumption device exceeds the upper limit of the preset temperature range, it indicates that the wind shield is severely blocked and can no longer meet the heat dissipation conditions. The wind shield must be cleaned, otherwise the heat dissipation effect will be affected; if the temperature of the power consumption device meets the preset temperature range, or the temperature of the power consumption device is lower than the lower limit of the preset temperature range, it indicates that although the wind shield is blocked, it can still meet the current heat dissipation requirements and does not affect the current heat dissipation effect. Therefore, you can choose whether to clean the wind shield.

[0037] In an optional embodiment, after obtaining the congestion handling strategy, it also includes: generating and sending a congestion prompt based on the congestion handling strategy. It should be noted that when the wind pressure exceeds the preset pressure range, it indicates that the windshield is blocked to varying degrees, so regardless of the power consumption device temperature and wind pressure, a corresponding congestion prompt will be generated.

[0038] In an optional embodiment, the heat dissipation method is determined according to the power consumption device temperature, wind pressure and system load, combined with preset heat dissipation control rules, and also includes: based on the wind pressure meeting the preset pressure range, determining the blockage processing strategy as not cleaning the wind shield, and determining whether the power consumption device temperature meets the preset temperature range; based on the power consumption device temperature exceeding the upper limit temperature of the preset temperature range, if the system load exceeds the preset load range, determining the load adjustment strategy as reducing the load; otherwise, determining the fan adjustment strategy as increasing the fan speed; based on the power consumption device temperature meeting the preset temperature range, if the system load exceeds the preset load range, determining the fan adjustment strategy as increasing the fan speed, otherwise, determining the fan adjustment strategy as not adjusting the fan speed; based on the power consumption device temperature being lower than the lower limit temperature of the preset temperature range, if the system load exceeds the preset load range, determining the fan adjustment strategy as increasing the fan speed, otherwise, determining the fan adjustment strategy as not adjusting the fan speed.

[0039] It should be added that when the wind pressure is within the preset pressure range, the temperature of the power-consuming device exceeds the upper limit of the preset temperature range. At this time, the fan heat dissipation is insufficient. If the system load exceeds the preset load range, the server system temperature will further increase, so the equipment load needs to be reduced.

[0040] In addition, based on the fact that the temperature of the power consumption device is within the preset temperature range, if the system load exceeds the preset load range, the server system temperature will further increase. At this time, since the temperature of the power consumption device is within the preset temperature range, it means that the fan can meet the heat dissipation requirements. Therefore, the fan speed can be increased in advance to effectively prevent the server system temperature from further increasing, so that the equipment can quickly enter a balanced state.

[0041] In addition, based on the fact that the temperature of the power-consuming device is lower than the lower limit of the preset temperature range, if the system load exceeds the preset load range, at this time, the fan can meet the heat dissipation requirements, and the fan speed can be increased in advance to effectively prevent the server system temperature from further increasing, so that the equipment can quickly enter balance; if the system load meets the preset load range, since the temperature of the power-consuming device is lower than the lower limit of the preset temperature range, the fan speed can be reduced to save energy.

[0042] S13, controlling the server to dissipate heat according to the heat dissipation method.

[0043] In an optional embodiment, if the determined fan adjustment strategy is to increase or decrease the fan speed, the server is controlled to dissipate heat according to the heat dissipation method, including: adjusting the fan speed using a preset PID control algorithm according to the power consumption device temperature, wind pressure and system load.

[0044] Furthermore, the fan speed is adjusted according to the power consumption device temperature, wind pressure and system load using a preset PID control algorithm, including: determining the fan speed according to the power consumption device temperature, wind pressure and system load using a preset PID control algorithm, and adjusting the fan according to the determined fan speed; reacquiring the power consumption device temperature, wind pressure and system load, and determining whether the reacquired power consumption device temperature is lower than the target temperature; if the reacquired power consumption device temperature is not lower than the target temperature, re-determining the fan speed according to the reacquired power consumption device temperature, wind pressure and system load using a preset PID control algorithm, and adjusting the fan according to the re-determined fan speed, and reacquiring the power consumption device temperature, wind pressure and system load, and determining whether the reacquired power consumption device temperature is lower than the target temperature, until the reacquired power consumption device temperature is lower than the target temperature and stopping.

[0045] It should be noted that by monitoring the power consumption device temperature, wind pressure and system load, and using the PID control algorithm, the fan speed can be accurately determined so that the fan speed can be continuously adjusted according to the real-time changing power consumption device temperature, wind pressure and system load to ensure that the fan provides appropriate heat dissipation air volume and improve the reliability and stability of the system.

[0046] In an alternative embodiment, reference Figure 4 The method further includes: monitoring the system load; predicting the temperature of the power consumption device according to the monitored system load to obtain a predicted temperature; and adjusting the fan speed according to the predicted temperature using a preset PID control algorithm.

[0047] It should be noted that by monitoring the system load, the server system can be prevented from being affected by the increased load and causing the temperature of the power consumption device to rise, so as to intervene in advance to adjust the fan speed, so as to provide sufficient heat dissipation air volume, effectively prevent the temperature from rising sharply and causing damage to the hardware, and ensure dynamic adaptation to load fluctuations, and then adjust the fan speed according to different load conditions to always maintain the best heat dissipation effect. In addition, according to the predicted temperature, the fan speed is adjusted using the preset PID control algorithm. Please refer to the above, and no further description is given here. It should be noted that when the load is monitored to intervene in advance to adjust the fan speed, the specific method of adjusting the fan can also be determined in combination with the temperature. Specifically, please refer to the above to determine the heat dissipation method when the wind pressure meets the preset pressure range, and no repetition will be made here.

[0048] In summary, the embodiments of the present invention obtain the temperature of power-consuming devices, wind pressure and system load to fully understand the working status and heat dissipation requirements of the server, thereby comprehensively considering these parameters and combining customized preset heat dissipation control rules to ensure that in different server working scenarios and states, the appropriate heat dissipation method is accurately determined to control the heat dissipation of the server.
