[0038] See also Figure 1 , Figure 1 FIG. 1 is a flow chart of a fan speed regulation method provided by an embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:

[0039] S1, obtaining the air inlet temperature of the target component.

[0040] In a specific implementation, the target component refers to a component in a server, such as a chip, etc., which is not specifically limited in this application. The inlet air temperature of the target component refers to the temperature of the wind blowing toward the target component, that is, the initial temperature of the wind used to dissipate heat for the target component. In the present invention, the temperature of the target component itself is not directly obtained, but the inlet air temperature of the target component is obtained.

[0041] In one embodiment, the above step of “obtaining the air inlet temperature of the target component” specifically includes: obtaining the air inlet temperature of the target component based on a target temperature sensor corresponding to the target component, wherein the target temperature sensor is disposed at the air inlet of the target component.

[0042] In a specific implementation, the air inlet may be specifically an air inlet, which is not specifically limited in this application. The target temperature sensor is used to detect the temperature of the wind at the air inlet of the target component and transmit the detected temperature to a controller, such as a BMC.

[0043] S2, obtaining an air volume adjustment parameter corresponding to the inlet air temperature.

[0044] In a specific implementation, an air volume adjustment parameter is preset for each air inlet temperature. The air volume adjustment parameter is used to determine whether the air volume of at least the current fan needs to be adjusted.

[0045] In one embodiment, the above step of "obtaining the air volume adjustment parameter corresponding to the inlet air temperature" specifically includes: obtaining a preset inlet air temperature-air volume adjustment parameter correspondence relationship; and querying the air volume adjustment parameter corresponding to the inlet air temperature in the inlet air temperature-air volume adjustment parameter correspondence relationship.

[0046] In a specific implementation, the corresponding relationship between the inlet air temperature and the air volume adjustment parameters can be specifically a table, for example, as shown in Table 1 below, which is a Close loop speed regulation parameter table based on the inlet air temperature and the inlet air volume.

[0047] Table 1. Close loop speed control parameters based on inlet air temperature and inlet air volume

[0048]

[0049]

[0050] Among them, the air volume adjustment parameters include the lower limit value Q down And the upper limit of air volume Q up .

[0051] In Table 1, T inlet Refers to the air inlet temperature of the component;

[0052] Q up Refers to the upper limit of the air volume for the fan speed adjustment of the component;

[0053] Q down Refers to the lower limit of the air volume for the fan speed adjustment of the component;

[0054] S up Indicates that every 1 second, the fan PWM increases, indicating the fan speed increase rate;

[0055] S down It means that every 1 second, the fan PWM value decreases, indicating the fan speed decrease rate.

[0056] Therefore, the air inlet temperature T can be found through Table 1. inlet Corresponding air volume lower limit Q down And the upper limit of air volume Q up .

[0057] Furthermore, in the present invention, Table 2, a component heat dissipation boundary table, is also preset.

[0058] Table 2. Component heat dissipation boundary table

[0059]

[0060] Among them, Q min (CFM) refers to the component at the inlet air temperature T inlet The minimum air volume required.

[0061] Understandably, the minimum air volume Q min Less than the lower limit of air volume Q down And the upper limit of air volume Q up .

[0062] S3, obtaining the air volume of the fan corresponding to the target component, and determining whether the air volume of the fan needs to be adjusted according to the air volume adjustment parameter.

[0063] In one embodiment, the air volume adjustment parameters include an air volume lower limit value and an air volume upper limit value. The above step of "determining whether the air volume of the fan needs to be adjusted based on the air volume adjustment parameters" specifically includes: determining whether the air volume of the fan is between the air volume lower limit value and the air volume upper limit value; if the air volume of the fan is between the air volume lower limit value and the air volume upper limit value, determining that the air volume of the fan does not need to be adjusted; if the air volume of the fan is not between the air volume lower limit value and the air volume upper limit value, determining that the air volume of the fan needs to be adjusted.

[0064] For example, in one embodiment, the air inlet temperature is 25°C. See Table 1, the corresponding air volume lower limit value Q down is 12 and the upper limit value of air volume Q up is 15, determining whether the air volume of the fan is between 12 and 15;

[0065] If the fan air volume is between 12 and 15, there is no need to adjust the fan air volume; if the fan air volume is not between 12 and 15, you need to adjust the fan air volume.

[0066] S4: If the air volume of the fan needs to be adjusted, adjust the air volume of the fan based on the air volume adjustment parameter.

[0067] In a specific implementation, if the air volume of the fan needs to be adjusted, the air volume of the fan is adjusted according to the air volume adjustment parameter.

[0068] In one embodiment, the above step of "adjusting the air volume of the fan based on the air volume adjustment parameter" specifically includes: determining whether the air volume of the fan is greater than the air volume upper limit value; if the air volume of the fan is greater than the air volume upper limit value, reducing the air volume of the fan so that the air volume of the fan is between the air volume lower limit value and the air volume upper limit value.

[0069] In a specific implementation, if the air volume of the fan is greater than the upper limit of the air volume, it means that the current air volume has a surplus and is sufficient to heat the target component. In order to save energy and reduce noise, in an embodiment of the present invention, the air volume of the fan is reduced.

[0070] In one embodiment, the above step of “reducing the air volume of the fan” includes: reducing the PWM value of the control signal of the fan.

[0071] In the specific implementation, based on S in Table 1 down To adjust the fan's PWM. down It means that every 1 second, the fan PWM value decreases, indicating the fan speed decrease rate.

[0072] In one embodiment, the above step of "adjusting the air volume of the fan based on the air volume adjustment parameter" specifically includes: determining whether the air volume of the fan is less than the lower limit value of the air volume; if the air volume of the fan is less than the lower limit value of the air volume, increasing the air volume of the fan so that the air volume of the fan is between the lower limit value of the air volume and the upper limit value of the air volume.

[0073] In a specific implementation, if the air volume of the fan is less than the lower limit of the air volume, it means that the air volume of the fan is insufficient to dissipate heat for the target component. Then, the air volume of the fan is increased so that the target component can be reliably dissipated.

[0074] In one embodiment, increasing the air volume of the fan includes: increasing a PWM value of a control signal of the fan.

[0075] In the specific implementation, based on S in Table 1 up To adjust the fan's PWM. up It means that every 1 second, the fan PWM value increases, indicating the rate at which the fan speed increases.

[0076] In the technical solution of the embodiment of the present invention, the inlet air temperature of the target component is obtained; the air volume adjustment parameter corresponding to the inlet air temperature is obtained; the air volume of the fan corresponding to the target component is obtained, and it is determined whether the air volume of the fan needs to be adjusted according to the air volume adjustment parameter; if the air volume of the fan needs to be adjusted, the air volume of the fan is adjusted based on the air volume adjustment parameter; in the present invention, the inlet air temperature of the target component is obtained, and it is automatically determined whether the air volume of the fan needs to be adjusted according to the inlet air temperature, the air volume of the fan and the preset air volume adjustment parameter, and the air volume is automatically adjusted when the air volume needs to be adjusted, thereby ensuring reliable heat dissipation of the target component. At the same time, when the temperature sensor I2C of the component chip cannot be accessed and the temperature value cannot be obtained, the air volume of the fan can be automatically adjusted according to the inlet air temperature based on the method of the present invention, thereby avoiding adjusting the air volume of the fan to the maximum, thereby effectively reducing noise and saving energy.
