As shown in fig. 1A, the method of the present disclosure may be applied to a server 100, where the server 100 includes a system fan 101, the system fan 101 may be composed of one or more fans, and the system fan 101 is used to dissipate heat of electronic components such as a CPU, a memory, and the like. The notebook computer further includes a PSU Power supply (Power supply unit) 102, and a fan, which may be called a PSU fan, is also disposed in the PSU Power supply 102, and the PSU fan is used for dissipating heat of a heat generating device in the PSU Power supply 102.
In order to ensure the performance of the mechanical hard disk, the distance between the system fan 101 and the mechanical hard disk is usually increased as much as possible, so as to reduce the influence of fan vibration and noise on the mechanical hard disk, the mechanical hard disk is basically installed on the front panel of the server in consideration of the thermal maintenance requirement, and the system fan 101 is arranged on the rear panel of the server and is close to the PSU power supply 102.

Fig. 2 schematically illustrates a flow chart of a method for controlling an airflow driver according to an embodiment of the disclosure.
As shown in fig. 2, the method includes operations S210 to S230.
In operation S210, monitoring information is obtained.
In operation S220, a current airflow direction in the flow channel where the target airflow driving device is located is determined based on the monitoring information.
In operation S230, in a case where the current air flow direction is opposite to a predetermined air flow direction, the rotation speed of the target air flow driving device is controlled to be increased such that the air flow direction in the flow channel is the same as the predetermined air flow direction, wherein the predetermined air flow direction is an air flow direction corresponding to the turning of the target air flow driving device.
According to an embodiment of the present disclosure, the airflow driving device may refer to a fan. The monitoring information may be related to the target airflow driving device to be controlled, and may be, for example, sensing information of a sensor provided in an airflow path in which the target airflow driving device is located. In the case where the target airflow driver is a PSU fan, the monitoring information may be, for example, sensing information of a sensor provided in the PSU power supply.
The current airflow direction in the flow channel where the target airflow driving device is located can be judged in real time according to the monitored data, and whether the current airflow direction is consistent with the airflow direction driven by the operation of the target airflow driving device or not is judged. And if the air flows are consistent with each other, the air duct where the target air flow driving device is located is determined not to have backflow. If the target airflow driving device and the target airflow driving device are inconsistent, the air channel where the target airflow driving device is located is judged to have backflow, and under the condition, the rotating speed of the target airflow driving device can be controlled to be increased, so that the air pressure of the target airflow driving device is increased, the airflow direction in the flow channel is changed to be consistent with the airflow direction driven by the operation of the target airflow driving device, and the airflow direction is recovered to be the normal flow direction.
According to the embodiment of the disclosure, whether the flow channel where the airflow driving device is located reflows or not can be monitored, and the rotating speed of the airflow driving device is controlled to be increased when the backflow occurs, so that the backflow problem is solved, and adverse effects on heat dissipation and the service life of the airflow driving device caused by the backflow of the flow channel are avoided.
According to an embodiment of the present disclosure, the obtaining of the monitoring information of operation S210 may include: temperature information collected by a first temperature sensor and a second temperature sensor disposed in the flow channel is obtained, e.g., the first temperature sensor and the second temperature sensor may be located at different axial locations of the flow channel. And, the first temperature sensor and the second temperature sensor are respectively located at both sides of the heat generating element in the flow passage.
Fig. 3A, 3B schematically illustrate a schematic structural diagram of a PSU power supply according to an embodiment of the present disclosure.
As shown in fig. 3A and 3B, in the case where the target airflow driving device is a PSU fan 301, a first temperature sensor 302 and a second temperature sensor 303 may be provided in the PSU power supply 300. The first temperature sensor 302 may be disposed at a position close to the PSU fan 301, i.e., close to the outlet of the PSU power supply. The first temperature sensor 302 may be disposed inside the PSU power supply in an airflow path of the PSU power supply. The second temperature sensor 303 may be disposed at an air inlet of the PSU power supply and may also be located in an airflow path of the PSU power supply. The heat generating device of the PSU power supply is located between the first temperature sensor 302 and the second temperature sensor 303.
According to an embodiment of the present disclosure, the determining, based on the monitoring information, the current airflow direction in the flow channel where the target airflow driving device is located in operation S220 includes: in the case that the temperature collected by the first temperature sensor 302 is higher than the temperature collected by the second temperature sensor 303, the current airflow direction is the direction from the second temperature sensor 303 to the first temperature sensor 302; in the case where the temperature collected by the first temperature sensor 302 is lower than the temperature collected by the second temperature sensor 303, the current airflow direction is the direction from the first temperature sensor 302 to the second temperature sensor 303.
If the temperature collected by the first temperature sensor 302 is higher than the temperature collected by the second temperature sensor 303, the heat representing the heat generating device is blown to the side where the first temperature sensor 302 is located, and thus the airflow direction is the direction from the second temperature sensor 303 to the first temperature sensor 302, i.e., the direction from left to right in the orientation shown in fig. 3A and 3B. The airflow direction driven by the operation of the PSU fan 301 is, for example, a left-to-right direction, in which case the current airflow direction in the PSU channel is consistent with the predetermined airflow direction corresponding to the rotation direction of the PSU fan 301.
If the temperature collected by the second temperature sensor 303 is higher than the temperature collected by the first temperature sensor 302, the heat representing the heat generating device is blown to the side where the second temperature sensor 303 is located, and thus the airflow direction is the direction from the first temperature sensor 302 to the second temperature sensor 303, i.e., the direction from right to left in the orientation shown in fig. 3A and 3B. The airflow direction driven by the operation of the PSU fan 301 is, for example, a left-to-right direction, in this case, the current airflow direction in the PSU power supply flow channel is not consistent with the predetermined airflow direction corresponding to the rotation direction of the PSU fan 301, and the flow channel of the PSU power supply reflows.
According to the embodiment of the disclosure, the current airflow direction is determined by using the temperature sensor, so that the current airflow direction can be accurately judged, and the device is simple in setting and low in cost.
In addition to determining the current airflow direction using the temperature collected by the temperature sensor, the current airflow direction may be determined in the following manner.
According to an embodiment of the present disclosure, the obtaining of the monitoring information of operation S210 may include: and obtaining a first operating parameter of the target airflow driving device and a second operating parameter of the related airflow driving device acting on the same electronic equipment with the target airflow driving device. The operation parameters may include parameters such as the rotation speed and the power of the airflow driving device.
For example, the PSU fan and the system fan may act on the same electronic device, and the operation parameter of the PSU fan may be acquired as the first operation parameter, and the operation parameter of the system fan may be acquired as the second operation parameter.
According to an embodiment of the present disclosure, the determining the current airflow direction in the flow channel where the target airflow driving device is located based on the monitoring information in operation S220 may include: and determining that the current airflow direction is opposite to the preset airflow direction under the condition that the first operation parameter and the second operation parameter meet the preset condition.
For example, the predetermined condition may include a difference between the first operating parameter and the second operating parameter being greater than a threshold value, or may include the first operating parameter and the second operating parameter each belonging to a respective predetermined range of values.
According to an embodiment of the present disclosure, a test may be performed in advance to obtain a predetermined condition. For example, it may be tested in advance how much the difference between the first operating parameter and the second operating parameter exceeds, the duct in which the target airflow driver is located will have backflow. For another example, it may be tested in advance what value ranges the first operating parameter and the second operating parameter respectively belong to, and the air duct where the target airflow driving device is located may have backflow. For another example, a plurality of reference values of the first operating parameter may be given, a value of the second operating parameter when backflow occurs is tested corresponding to each reference value of the first operating parameter, a reference corresponding table of the first operating parameter and the second operating parameter is established, when operation S220 is executed, a reference first operating parameter close to the current first operating parameter may be searched from the table, and a reference second operating parameter corresponding to the reference first operating parameter is determined, and if the current second operating parameter is greater than the reference second operating parameter, it may be considered that backflow occurs in the air duct where the target airflow driving device is located.
In addition, a wind pressure sensor, a wind speed sensor, and the like may be disposed in the flow channel where the target airflow driving device is located, so that the pressure or the wind speed of the airflow in a certain direction may be measured, for example, the pressure or the wind speed of the airflow in the left-to-right direction in the orientation shown in fig. 3A and 3B may be measured. If the pressure or the wind speed can be measured, the current airflow direction can be considered to be consistent with the measured direction, if the pressure or the wind speed cannot be measured, the current airflow direction can be considered to be inconsistent with the measured direction, and whether the current airflow direction is consistent with the preset airflow direction corresponding to the target airflow driving device or not can be judged.
According to an embodiment of the present disclosure, the controlling of the rotation speed increase of the target airflow driving device in operation S230 may include: and controlling the target airflow driving device to increase the speed at least once, wherein the rotating speed of the target airflow driving device is increased by a preset value every time of increasing the speed until the airflow direction in the flow channel is the same as the preset airflow direction.
For example, each time an additional Δ PWM is given to the target airflow driver, the rotational speed of the target airflow driver is increased by Δ n until the airflow direction in the flow path is monitored to be the same as the predetermined airflow direction. The PWM (pulse width modulation) is pulse width modulation, and is used to control the rotation speed of the fan, and the Δ PWM can be set according to actual requirements.
Another aspect of the embodiments of the present disclosure also provides a control device for controlling an airflow driving device.
