[0049] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0050] The time required for the fan to increase from the starting speed A (RPM) to the target speed B (RPM) is called the speed time difference. Figure 1 The fan speed time difference is shown in the figure. Figure 1 As shown, the time required for the fan to go from a starting speed point A (such as X1, Y1, Z1) to a target speed point B (such as X2, Y2, Z2) is (X_Time, Y_Time, Z_Time).

[0051] However, after the fan has been used for a period of time, due to wear, dust accumulation and other reasons, the time required for the fan to change from the initial speed A to the target speed B will increase compared to when it leaves the factory. Figure 2 It shows the speed time difference of the fan after it has been used for a period of time. Figure 2As shown, the time required for the fan to go from the starting speed point A (such as Xp1, Yp1, Zp1) to the target speed point B (such as Xp2, Yp2, Zp2) is (Xp_Time, Yp_Time, Zp_Time). Figure 3 As shown, Xp1, Yp1, Zp1 are the same as X1, Y1, Z1, and X2, Y2, Z2 are the same as Xp2, Yp2, Zp2, but the required time is increased. Therefore, the heat dissipation efficiency of the fan will be affected.

[0052] Figure 4 FIG. 2 is a schematic diagram showing a flow chart of a fan adjustment method according to an embodiment of the present disclosure. Figure 4 As shown, according to a first aspect of an embodiment of the present disclosure, a fan adjustment method is provided, the method comprising:

[0053] Step 101, based on the actual temperature of the device where the fan is located, control the fan to a preset speed.

[0054] Computers usually perform thermal management based on a Thermal Table. Thermal Table refers to a table that sets the correspondence between different temperature levels and fan speed levels, and is used to adjust the fan speed according to the actual temperature of the system or component. Specifically, the Thermal Table defines the fan speed levels corresponding to different temperature levels. When the system's temperature sensor detects that the temperature has risen to a preset threshold, the thermal management system will find the fan speed level corresponding to the temperature according to the Thermal Table, and adjust the fan speed accordingly. Similarly, if the temperature drops below a specific threshold, the system will also adjust the fan speed accordingly. In step 101, the current actual temperature of the device is first obtained through the temperature sensor, and then the fan speed corresponding to the current actual temperature is found in the Thermal Table as the preset speed, and the fan is adjusted to this speed.

[0055] Step 102, obtaining the temperature change of the device and the time taken for the change.

[0056] The temperature change refers to the degree to which the device temperature rises or falls before and after the fan is turned on. The change time refers to the time it takes for this temperature change to occur.

[0057] For example, in step 101, the temperature sensor detects that the current actual temperature of the device is 40°C. The ThermalTable records that the fan speed corresponding to 40°C is 3000RPM. The fan is controlled to rotate at 3000RPM to reduce the temperature of the device. The temperature change of the device and the required time are obtained. For example, it takes 100 seconds to reduce the temperature from 40°C to 30°C, that is, to reduce the temperature by 10°C.

[0058] Step 103: determining the actual heat dissipation efficiency of the fan according to the temperature change and the time taken for the change.

[0059] Based on the temperature change and the time it takes to change, the fan's ability to remove heat from the device per unit time, i.e., the actual heat dissipation efficiency, is calculated.

[0060] Step 104: Compare the actual heat dissipation efficiency with the reference heat dissipation efficiency to obtain an efficiency deviation value.

[0061] The reference heat dissipation efficiency refers to the efficiency measured when the fan leaves the factory, which represents the performance level that the fan should have. By comparison, an efficiency deviation value can be obtained. The efficiency deviation value reflects the difference between the actual heat dissipation efficiency and the ideal state. Specifically, the efficiency deviation can be determined by the ratio or difference between the actual heat dissipation efficiency and the reference heat dissipation efficiency.

[0062] Step 105: adjusting the preset rotation speed based on the efficiency deviation value.

[0063] Based on the obtained efficiency deviation value, the preset speed of the fan is adjusted. If the actual cooling efficiency is lower than the reference cooling efficiency, the speed of the fan needs to be increased to improve its cooling capacity. On the contrary, if the actual cooling efficiency is higher than the reference cooling efficiency, the speed of the fan needs to be reduced to save energy and reduce noise. If the actual cooling efficiency is equal to the reference cooling efficiency, the speed of the fan is maintained at the preset speed.

[0064] Compared with the prior art that controls the fan according to the fixed speed in the Thermal Table, the fan adjustment method of this embodiment monitors the actual heat dissipation efficiency of the fan, and when there is a deviation between the actual heat dissipation efficiency and the factory heat dissipation efficiency, the fan speed is intelligently and dynamically adjusted in time, thereby significantly improving the heat dissipation efficiency of the fan. This can ensure that the equipment can operate efficiently and sustainably under high load, while enhancing the user experience, extending the service life of the equipment, and significantly improving the market competitiveness and technical advantages of the product.

[0065] In one embodiment of the present disclosure, the preset speed is adjusted based on the efficiency deviation value, which can be specifically achieved through the following technical means: if the efficiency deviation value satisfies the preset deviation range, the fan speed is maintained at the preset speed; if the efficiency deviation value does not satisfy the preset deviation range, the fan speed is adjusted from the preset speed to the optimized speed.

[0066] The preset deviation range is a numerical range used to determine whether the efficiency deviation value is within an acceptable or ideal range. It can be determined based on factors such as the heat dissipation requirements of the equipment, the performance characteristics of the fan, and the user's usage habits, to ensure that the heat dissipation requirements are met while maintaining low energy consumption and noise. The specific value can be set according to the actual situation, such as ±5%. If the efficiency deviation value is detected to be within the preset deviation range, it means that the current fan speed is sufficient to meet the heat dissipation requirements and will not cause excessive energy consumption and noise. The fan speed is maintained at the preset speed. If the efficiency deviation value does not meet the preset deviation range, it means that the current fan speed is either too high, resulting in increased energy consumption and noise, or too low to meet the heat dissipation requirements. In this case, the fan speed is adjusted from the preset speed to a better optimized speed according to the actual situation.

[0067] In one embodiment of the present disclosure, if the efficiency deviation value does not satisfy the preset deviation range, the speed of the fan is adjusted from the preset speed to the optimized speed, which can be achieved by the following technical means: if the efficiency deviation value is less than the lower limit of the preset deviation range, the speed of the fan is adjusted from the preset speed to the first optimized speed; if the efficiency deviation value is greater than the upper limit of the preset deviation range, the speed of the fan is adjusted from the preset speed to the second optimized speed; wherein, the first optimized speed is greater than the preset speed, and the second optimized speed is less than the preset speed.

[0068] When the efficiency deviation value is less than the lower limit of the preset deviation range, it indicates that the degree to which the current heat dissipation efficiency of the fan is lower than the reference heat dissipation efficiency exceeds the acceptable range. The fan speed is adjusted from the preset speed to a higher optimized speed, i.e., the first optimized speed. When the efficiency deviation value is greater than the upper limit of the preset deviation range, it indicates that the degree to which the actual heat dissipation efficiency is higher than the reference heat dissipation efficiency exceeds the acceptable range. The fan speed is adjusted from the preset speed to a lower optimized speed, i.e., the second optimized speed.

[0069] In one embodiment of the present disclosure, the temperature change and change time of the device are obtained, specifically: the device temperature is monitored in real time by a sensor, and the temperature change data of the device during operation is collected in real time, including the specific temperature change and the time period in which these changes occur.

[0070] In one embodiment of the present disclosure, based on the preset speed, a reference heat dissipation efficiency corresponding to the preset speed is obtained. Each level of speed corresponds to a reference heat dissipation efficiency. Based on the current speed of the fan, that is, the preset speed, the corresponding reference heat dissipation efficiency is obtained.

[0071] In one embodiment of the present disclosure, the method further includes: generating optimization data for the fan based on the number of times the preset rotation speed is adjusted.

[0072] The number of times the preset speed is adjusted refers to the number of times the system automatically adjusts the fan speed because the heat dissipation efficiency does not meet the reference heat dissipation efficiency within a period of time, that is, the optimization frequency. This number is used as an indicator, combined with the time when the adjustment occurs, the speed value before and after the adjustment, and the efficiency deviation that causes the adjustment, etc., to generate optimization data for the fan. The optimization data may include the average adjustment frequency of the fan under different working conditions, whether the fan needs to be repaired or replaced, etc.

[0073] The method of the present disclosure is described below by a specific implementation method. Figure 5 As shown, the method includes: when the computer is in S0 state (i.e., normal working state). Enable data, including the speed characteristic curve of the fan and reference heat dissipation efficiency and other data. Determine whether the current temperature of the computer triggers the Thermal Table. If not triggered, reduce the fan speed or stop the fan. If triggered, start the fan to a preset speed. And report the current temperature, temperature change and the time taken for the change, preset speed, current actual fan speed and other information through EC (Embedded Controller). Combined with the above information, determine whether the deviation between the actual heat dissipation efficiency of the fan and the reference heat dissipation efficiency meets the preset deviation range. If yes, maintain the current speed. If not yes, automatically increase or decrease the fan speed. Until the computer enters S4 (i.e., sleep state) or S5 (i.e., shutdown state).

[0074] According to another aspect of the present disclosure, a fan adjustment device is provided. Figure 6 A schematic diagram of the structure of a fan adjustment device according to an embodiment of the present disclosure is shown. Figure 6 As shown, the device comprises:
