In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention will be described in further detail with reference to the accompanying drawings.
It should be noted that, in the embodiments of the present invention, all the expressions "first" and "second" are used to distinguish two entities with the same name but different entities or different parameters, and it is noted that the "first" and "second" are only used for convenience of expression, and should not be construed as limiting the embodiments of the present invention, and the following embodiments are not described one by one.
Based on the above object, in a first aspect of the embodiments of the present invention, an embodiment of a method for adjusting a rotational speed of a fan of a server is provided. As shown in fig. 1, it includes the steps of:
s10, a heat dissipation model is established, and calibration is carried out on the heat dissipation model;
s20, acquiring the real-time temperature and the target temperature of the first target component based on the calibrated heat radiation model, and comparing the real-time temperature with the target temperature;
s30, outputting a first rotating speed based on the calibrated heat dissipation model to adjust the rotating speed of the fan based on the first rotating speed in response to the real-time temperature not being greater than the target temperature;
and S40, outputting a second rotating speed based on the calibrated heat dissipation model to adjust the rotating speed of the fan based on the second rotating speed in response to the real-time temperature being greater than the target temperature.
Specifically, firstly, a heat dissipation model can be built by building a test environment, actually measuring the relation between the temperature of each main component in the server and the ambient temperature and the rotation speed of a fan, wherein the heat dissipation model comprises a first expression and a second expression, the first expression is based on heating power and the rotation speed, after the first expression is calibrated, the first expression is used for outputting the first rotation speed based on real-time heating power, and the second expression is based on the temperature and the rotation speed and is used for outputting the second rotation speed based on real-time temperature. And then, reading the real-time temperature and the target temperature of the target component, wherein the target temperature is a temperature set in advance, when the real-time temperature is higher than the target temperature, rapidly calculating the second rotating speed based on the calibrated heat dissipation model, adjusting the rotating speed of the fan through the second rotating speed, and when the real-time temperature is not higher than the target temperature, rapidly calculating the first rotating speed based on the calibrated heat dissipation model, and adjusting the rotating speed of the fan through the first rotating speed.
The target component may be a representative and important component in the server chassis, such as a motherboard, a memory, a PCH (Platform Controller Hub, integrated south bridge), a GPU (Graphic Processing Units, a graphics processor), a network card, a hard disk, and the like. The input parameters can be parameters such as power output power, real-time power of a fan, rotation speed of the fan, temperature of an air inlet, temperature of an air outlet, target temperature of a target part, real-time temperature and the like.
Through the scheme, the rotating speed of the fan can be quickly adjusted, the calculated amount of the rotating speed adjustment of the fan is reduced, and the heat dissipation energy consumption is reduced.
In a specific embodiment, the heat dissipation model includes a first expression and a second expression;
in step S10, the calibrating the heat dissipation model specifically includes the following steps:
s11, acquiring a first calibration parameter;
s12, calibrating the first expression based on the first calibration parameter;
s13, acquiring a second calibration parameter, and calibrating the second expression based on the second calibration parameter.
In a specific embodiment, the first calibration parameter includes power output power, fan rotation speed, air inlet temperature, air outlet temperature, and the like. The first expression may be calibrated by:
firstly, obtaining a plurality of groups of first calibration parameters through measurement, and respectively inputting each group of first calibration parameters into a third expression to obtain a corresponding first basic rotating speed, wherein the specific form of the third expression is as follows:
power output power-fan power= (air inlet temperature-air outlet temperature) ×f (x) x specific heat capacity coefficient, wherein f (x) is a function based on fan rotation speed and air supply quantity, and x is a basic rotation speed of the fan;
then, a function curve is fitted to the corresponding first basic rotation speed based on each set of first calibration parameters to obtain a first expression.
According to the embodiment of the invention, the rotating speed of the fan can be reduced as much as possible in the temperature range which satisfies the stable operation of all parts in the server, so that the heat dissipation energy consumption and the heat dissipation noise are reduced, and the optimal balance between the heat dissipation effect and the heat dissipation energy consumption is achieved.
The following describes the inventive concepts in connection with a specific first expression calibration process, it being understood that the embodiments described herein are for purposes of illustration and explanation only and are not intended to limit the invention.
Inputting parameters:
the power supply outputs power in real time, the fan rotates speed, the air inlet temperature and the air outlet temperature.
Output parameters:
the fan adjusts the rotational speed, i.e., the first rotational speed in the embodiment of the present invention.
Because the electric energy output by the server power supply is converted into mechanical energy of the fan and is finally emitted in a heat energy form, the real-time output power of the power supply is subtracted from the real-time power of the fan, namely heating power can be obtained; the heat productivity in unit time can be further calculated, and the heat dissipation capacity and the heat dissipation power can be calculated by combining the specific heat capacity of the air through the temperature difference between the air inlet and the air outlet and the air supply capacity of the fan (which can be obtained according to the rotating speed of the fan and is specifically calibrated by a fan manufacturer); in theory, when the heat dissipation power and the heat generation power are equal, the system temperature can not rise and fall any more, so that the basic rotating speed of the fan can be obtained. Therefore, a third expression is constructed for outputting the fan base rotation speed, the third expression being as follows:
the power supply output power-fan power= (air inlet temperature-air outlet temperature) ×f (x) ×specific heat capacity coefficient, wherein f (x) is a function based on fan rotation speed and air supply quantity, fan manufacturers specifically calibrate the function, x is the basic rotation speed of the fan, and the specific heat capacity coefficient is the specific heat capacity coefficient of air under normal pressure;
the first basic rotation speed of the fan can be obtained through the third expression.
However, starting from the server system, the temperature of the system is not increased and the temperature distribution inside the system is not necessarily uniform, and some parts are higher than the temperature of the system and other parts are lower than the temperature of the system, and important parts in the server, namely target parts, are selected and the temperature of the important parts is included in factors influencing the final regulation rotating speed of the fan. The basic rotation speed obtained in the prior art is corrected through the influence factors of the components, so that the system has better heat dissipation, and meanwhile, the internal temperature distribution of the system is more reasonable.
The correction process of the basic rotating speed is as follows: and obtaining a plurality of groups of first calibration parameters through multiple measurements in a test environment, inputting the first calibration parameters into a third expression to obtain a plurality of groups of data of heating power and corresponding fan rotating speed, and fitting a function curve between the heating power and the fan rotating speed, namely the first expression, based on the plurality of groups of data of the heating power and the corresponding fan rotating speed.
The server heat dissipation scheme of the invention better solves the problems of heat dissipation power consumption and heat dissipation efficiency of the server, the proportion of the heat dissipation power consumption in total energy consumption is further reduced, heat dissipation noise is also improved, considerable economic benefit and environmental protection benefit are realized in a large-scale deployment data center, interaction between a BMC (Baseboard Management Controller, a baseboard management controller) and a plurality of low-speed devices is reduced, the calculation processing pressure of the BMC is lightened, the operation efficiency is improved, and the heat dissipation calculation is relatively simpler, so that the whole is considered, and specific individual components are also considered.
In one embodiment, the second calibration parameter includes temperature and fan speed. The second expression may be calibrated by:
obtaining a plurality of groups of second calibration parameters through measurement;
fitting a function curve based on each set of second calibration parameters to obtain a fourth expression;
determining coefficients based on the fourth expression;
a second expression is obtained based on the coefficient, the actual temperature of the target member, and the target temperature.
Wherein the form of the second expression is as follows:
wherein F (rpm) represents the second basic rotation speed, A represents the coefficient, T represents the actual temperature, T obj Indicating the target temperature.
The following describes the inventive concepts in connection with a specific second expression calibration process, it being understood that the embodiments described herein are for illustration and explanation of the invention only and are not intended to be limiting.
Inputting parameters:
target temperature and real-time temperature of target component
Output parameters:
the fan adjusts the rotational speed, i.e., the second rotational speed in the embodiment of the present invention.
An optimum operating temperature obj_temp, i.e., a target temperature, is set for each target component, the target temperature being set based on an equilibrium point of operating stability and heat dissipation energy consumption.
When the temperature of the target component is lower than the target temperature, the influence of the component on the rotating speed of the fan is 0, when the temperature of the component is higher than the target temperature, the main body of the functional relation adopts a unitary quadratic function relation, so that the influence of the component on the rotating speed of the temperature is small when the temperature of the target component is slightly higher than the target temperature, and when the temperature is higher than the target temperature by more, the influence of the component on the rotating speed of the fan is large. On the basis, the function coefficient is calibrated, and the slope of the rotation speed along with the temperature change is changed, so that the influence on the rotation speed of the fan is smoother while the cooling of the component is met. Specifically, the influence of temperature on the rotation speed can be expressed based on the following second expression:
wherein F (rpm) represents the second basic rotation speed, A represents the coefficient, T represents the actual temperature, T obj Indicating the target temperature.
Multiple measurements in the actual environment are performed to fit the temperature T/rotation speed D relationship as shown in fig. 2, and a suitable function curve is calibrated, which is represented by a fourth expression.
And the fourth expression is equal to the second expression, so that the coefficient A of the second expression is obtained through calculation.
Since the positional relationship between the target member sensor and the fans is different, the weight of the sensor is also different for each fan, and thus a corresponding weight coefficient B is set for each sensor.
Second rotation speed=weight coefficient×second base rotation speed.
According to the server heat dissipation scheme, the problems of heat dissipation power consumption and heat dissipation efficiency of the server are better solved, the proportion of the heat dissipation power consumption in total energy consumption is further reduced, heat dissipation noise is improved, considerable economic benefits and environmental benefits are achieved in a large-scale deployment data center, interaction between a BMC and a plurality of low-speed devices is reduced, calculation processing pressure of the BMC is reduced, operation efficiency is improved, heat dissipation calculation is relatively simpler, and the whole is considered and specific individual components are also considered.
