[0054] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the following further describes the embodiments of the present invention in detail with reference to specific embodiments and the accompanying drawings.

[0055] It should be noted that all the expressions using "first" and "second" in the embodiments of the present invention are used to distinguish two entities or parameters with the same name but different identities. It can be seen that "first" and "second" are only for the convenience of expression and should not be construed as a limitation on the embodiments of the present invention. This will not be elaborated one by one in the subsequent embodiments.

[0056] Based on the above objectives, in the first aspect of the embodiments of the present invention, an embodiment of a method for adjusting the rotation speed of a server fan is proposed. As Figure 1 shown, it includes the following steps:

[0057] S10. Establish a heat dissipation model and calibrate the heat dissipation model;

[0058] S20. Obtain the real-time temperature and target temperature of the first target component based on the calibrated heat dissipation model, and compare the real-time temperature with the target temperature;

[0059] S30. In response to the real-time temperature being not greater than the target temperature, output a first rotation speed based on the calibrated heat dissipation model to adjust the fan rotation speed based on the first rotation speed;

[0060] S40. In response to the real-time temperature being greater than the target temperature, output a second rotation speed based on the calibrated heat dissipation model to adjust the fan rotation speed based on the second rotation speed.

[0061] Specifically, first, the relationship between the temperatures of the main components inside the server, the ambient temperature, and the fan rotation speed can be actually measured by building a test environment to establish a heat dissipation model. The heat dissipation model includes a first expression and a second expression. The first expression is an expression based on the heat generation power and the rotation speed. After calibrating the first expression, it is used to output a first rotation speed based on the real-time heat generation power. The second expression is an expression based on the temperature and the rotation speed, and is used to output a second rotation speed based on the real-time temperature. Next, read the real-time temperature and target temperature of the target component. The target temperature is a pre-set temperature. When the real-time temperature is higher than the target temperature, quickly calculate the second rotation speed based on the calibrated heat dissipation model and adjust the fan rotation speed through the second rotation speed. When the real-time temperature is not higher than the target temperature, quickly calculate the first rotation speed based on the calibrated heat dissipation model and adjust the fan rotation speed through the first rotation speed.

[0062] Among them, the target components can be representative and important components inside the server chassis, such as the motherboard, memory, PCH (Platform Controller Hub), GPU (Graphic Processing Units), network card, hard disk and other components. The input parameters can be power output power, real-time fan power, fan speed, inlet temperature, outlet temperature, target temperature and real-time temperature of the target components, etc.

[0063] Through the above solution, the fan speed can be quickly adjusted, the calculation amount of fan speed adjustment is reduced, and the heat dissipation energy consumption is reduced.

[0064] In a specific embodiment, the heat dissipation model includes a first expression and a second expression;

[0065] In step S10, calibrating the heat dissipation model specifically includes the following steps:

[0066] S11. Obtain the first calibration parameter;

[0067] S12. Calibrate the first expression based on the first calibration parameter;

[0068] S13. Obtain the second calibration parameter and calibrate the second expression based on the second calibration parameter.

[0069] In a specific embodiment, the first calibration parameters include power output power, fan power, fan speed, inlet temperature, outlet temperature, etc. The first expression can be calibrated through the following solution:

[0070] First, obtain multiple groups of first calibration parameters through measurement, and input each group of first calibration parameters into the third expression to obtain the corresponding first basic speed. The specific form of the third expression is as follows:

[0071] Power output power - fan power = (inlet temperature - outlet temperature) × f(x) × specific heat capacity coefficient, where f(x) is a function based on fan speed and air delivery volume, and x is the basic speed of the fan;

[0072] Then, fit the function curve based on each group of first calibration parameters and the corresponding first basic speed to obtain the first expression.

[0073] In the embodiment of the present invention, within the temperature range that can ensure the stable operation of each component inside the server, the fan speed can be reduced as much as possible to reduce heat dissipation energy consumption and heat dissipation noise, and an optimal balance can be achieved between the heat dissipation effect and heat dissipation energy consumption.

[0074] The concept of the present invention will be described below in combination with a specific calibration process of a first expression. It should be understood that the embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0075] Input parameters:

[0076] Real-time output power of the power supply, real-time power of the fan, fan speed, inlet temperature, outlet temperature.

[0077] Output parameters:

[0078] Adjusted speed of the fan, i.e., the first speed in the embodiments of the present invention.

[0079] Since most of the electrical energy output by the server power supply is dissipated in the form of heat, except for being converted into mechanical energy of the fan, the heating power can be obtained by subtracting the real-time power of the fan from the real-time output power of the power supply; further, the heat generation per unit time can be calculated. By the temperature difference between the inlet and outlet and the air volume of the fan (which can be obtained according to the fan speed, and the fan manufacturer has specific calibration for this), and combined with the specific heat capacity of air, the heat dissipation and heat dissipation power can be calculated; theoretically, when the heat dissipation power is equal to the heating power, the system temperature should no longer rise or fall. Thus, a fan basic speed can be obtained. Therefore, a third expression is constructed to output the fan basic speed, and the form of the third expression is as follows:

[0080] Power supply output power - fan power = (inlet temperature - outlet temperature) × f(x) × specific heat capacity coefficient, where f(x) is a function based on the fan speed and air volume, the fan manufacturer has specific calibration for this function, x is the basic speed of the fan, and the specific heat capacity coefficient is the specific heat capacity coefficient of air under normal pressure;

[0081] The first basic speed of the fan can be obtained through the above third expression.

[0082] However, starting from the server system, although the system temperature no longer rises or falls, the temperature distribution inside the system is not necessarily uniform. There are some components higher than the system temperature and some components lower than the system temperature. Select important components in the server, i.e., target components, and incorporate their temperatures into the factors affecting the final adjusted speed of the fan. The basic speed obtained previously is corrected by the influence factors of these components, so that the system has better heat dissipation and the temperature distribution inside the system is more reasonable.

[0083] The process of correcting the basic speed is as follows: In the test environment, multiple groups of first calibration parameters are obtained through multiple measurements and input into the third expression to obtain multiple groups of data on heating power and corresponding fan speeds. Based on the multiple groups of data on heating power and corresponding fan speeds, a function curve between heating power and fan speed is fitted, i.e., the first expression.

[0084] Through the server heat dissipation solution of the present invention, the problems of heat dissipation power consumption and heat dissipation efficiency of the server are better solved, the proportion of heat dissipation power consumption in the total energy consumption is further reduced, the heat dissipation noise is also improved, and considerable economic and environmental benefits will be achieved in large-scale deployed data centers. The interaction between the BMC (Baseboard Management Controller) and multiple low-speed devices is reduced, the computing and processing pressure on the BMC is alleviated, the operation efficiency is improved, and the heat dissipation calculation becomes relatively simpler, taking into account both the overall situation and specific individual components.

[0085] In a specific embodiment, the second calibration parameter includes temperature and fan speed. The second expression can be calibrated through the following scheme:

[0086] Obtain multiple groups of second calibration parameters through measurement;

[0087] Fit a function curve based on each group of second calibration parameters to obtain a fourth expression;

[0088] Determine the coefficient based on the fourth expression;

[0089] Obtain the second expression based on the coefficient, the actual temperature of the target component, and the target temperature.

[0090] Among them, the form of the second expression is as follows:

[0091]

[0092] Among them, F(rpm) represents the second base speed, A represents the coefficient, T represents the actual temperature, and T obj represents the target temperature.

[0093] The following elaborates on the concept of the present invention in combination with a specific second expression calibration process. It should be understood that the embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0094] Input parameters:

[0095] The target temperature and real-time temperature of the target component

[0096] Output parameters:

[0097] The fan adjustment speed, that is, the second speed in the embodiment of the present invention.

[0098] Set an optimal working temperature obj_temp, that is, the target temperature, for each target component. The target temperature is set based on the balance point between working stability and heat dissipation energy consumption.

[0099] When the temperature of the target component is lower than the target temperature, the influence of the component on the fan speed is 0. When the component temperature is higher than the target temperature, the main function relationship adopts a quadratic function relationship, indicating that when the target component temperature is slightly higher than the target temperature, the influence of the component on the temperature and speed is small, and when the temperature is much higher than the target temperature, the influence of the component on the fan speed is large. On this basis, the function coefficients are calibrated to change the slope of the speed change with temperature, so that the influence on the fan speed can be made smoother while meeting the component cooling requirements. Specifically, the influence of temperature on speed can be expressed based on the following second expression:

[0100]

[0101] where F(rpm) represents the second base speed, A represents the coefficient, T represents the actual temperature, and T obj represents the target temperature.

[0102] Through multiple measurements in the actual environment, the relationship curve between temperature T / speed D as shown in Figure 2 is fitted, and at the same time, a suitable function curve is calibrated and represented by the fourth expression.

[0103] The fourth expression is equal to the second expression, and the coefficient A of the second expression is calculated accordingly.

[0104] Due to the different positional relationships between the target component sensors and the fans, the weights of the sensors for each fan are also different. Therefore, a corresponding weight coefficient B is set for each sensor.

[0105] The second speed = weight coefficient × second base speed.

[0106] Through the server heat dissipation solution of the present invention, the heat dissipation power consumption and heat dissipation efficiency problems of the server are better solved, the proportion of heat dissipation power consumption in the total energy consumption is further reduced, and the heat dissipation noise is also improved. There will be considerable economic and environmental benefits in large-scale deployed data centers, reducing the interaction between BMC and multiple low-speed devices, reducing the computing and processing pressure on BMC, improving the operation efficiency, and making the heat dissipation calculation relatively simpler, considering both the overall and specific individual components.

[0107] In a specific embodiment, the output of the first speed based on the calibrated heat dissipation model includes:

[0108] Obtain the first input parameter, and obtain the heat generation power based on the first input parameter;

[0115] Obtain the real-time temperature and the target temperature of the first target component, and input the difference between the real-time temperature and the target temperature of the first target component into the calibrated second expression to obtain a second basic rotational speed.

[0116] Specifically, in combination with Figure 3 The calculation process of the first basic rotational speed is described.

[0117] Obtain the power supply output voltage U1 * power supply output current I1 from the control unit inside the power management chip, and the power supply output power = power supply output voltage U1 × power supply output current I1;

[0118] Obtain the fan voltage U2 and the fan current I2 from the motherboard fan power management chip, and the fan power = fan voltage U2 × fan current I2.

[0124] In response to the real-time temperature of the second target component exceeding the temperature threshold, increase the fan rotational speed.

[0125] Specifically, the temperature of unimportant devices is also monitored, but the frequency of interaction can be reduced. As long as the temperature does not exceed the alarm value, no measures are taken. If the alarm value is exceeded, the rotation speed of the fan is increased by a fixed value on the basis of the calculated rotation speed to increase the rotation speed or directly increase the fan rotation speed to the maximum.
