And under the condition that the current airflow direction is opposite to the preset airflow direction, controlling the rotating speed of the target airflow driving device to be increased so as to enable the airflow direction in the flow channel to be the same as the preset airflow direction, wherein the preset airflow direction is the airflow direction corresponding to the steering direction of the target airflow driving device.
Fig. 1A, 1B, and 1C schematically illustrate exemplary application scenarios to which a method for controlling an air flow driving device according to an embodiment of the present disclosure may be applied. It should be noted that fig. 1 illustrates only an example of an application scenario in which the embodiments of the present disclosure may be applied to help those skilled in the art understand the technical content of the present disclosure, but it does not mean that the embodiments of the present disclosure may not be applied to other devices, systems, environments, or scenarios.
As shown in fig. 1A, the method of the embodiments of the present disclosure may be used for a server 100, where the server 100 includes a system fan 101, where the system fan 101 may be composed of one or more fans, and the system fan 101 is used to dissipate heat from electronic components such as a CPU, a memory, and the like. The notebook computer further includes a PSU power supply (Power supply unit, a power supply unit, also called a power supply) 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 to dissipate heat from a heat generating device in the PSU power supply 102.
To ensure the performance of the mechanical hard disk, the distance between the system fan 101 and the mechanical hard disk is generally increased as much as possible, so as to reduce the influence of vibration and noise of the fan on the mechanical hard disk, and the mechanical hard disk is basically installed on the front panel of the server in consideration of the requirement of thermal maintenance, and the system fan 101 is disposed on the rear panel of the server and is close to the PSU power supply 102.
As shown in fig. 1B, during normal operation, the system wind goes forward and backward, and the system fan 101 and PSU fan keep the wind direction consistent.
As shown in fig. 1C, when the rotational speed of the system fan 101 is greater, the wind pressure of the system fan 101 is greater than the wind pressure of the PSU fan, and when the pressure difference between the system fan 101 and the PSU fan is too large, the air duct in which the PSU fan is located will have a backflow phenomenon, and the air flow directions of the two air ducts are opposite. In this case, both the heat dissipation of the PSU power supply and the lifetime of the PSU fan are affected.
The method for controlling the airflow driving device can monitor whether the air duct where the PSU fan is located is reflowed or not, and control the rotation speed of the PSU fan to be increased when the reflow occurs so as to solve the reflow problem.
It will be appreciated that the application scenario in fig. 1 is only an example, and the method for controlling the airflow driving device may be applied to other devices and scenarios that may cause a backflow of a fan, for example, in the scenarios of electronic devices such as a desktop host computer, a notebook computer, and the like, in addition to the PSU fan of the control server.
Fig. 2 schematically illustrates a flow chart of a method for controlling an airflow driving device 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 a flow channel in which the target airflow driving device is located is determined based on the monitoring information.
In operation S230, in case that the current airflow direction is opposite to the predetermined airflow direction, the rotational speed of the target airflow driving device is controlled to be increased so that the airflow direction in the flow path is the same as the predetermined airflow direction, which is the airflow direction corresponding to the turn of the target airflow driving device.
According to embodiments 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, for example, may be sensing information of a sensor disposed in an airflow path in which the target airflow driving device is located. In case the target airflow driving device 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. If the air flows are consistent, the air channel where the target air flow driving device is located is considered to have no backflow. If the air flows are inconsistent, the air channel where the target air flow driving device is located is considered to have backflow, and under the condition, the rotating speed of the target air flow driving device can be controlled to be increased, so that the air pressure of the target air flow driving device is increased, the air flow direction in the flow channel is changed to be consistent with the air flow direction driven by the operation of the target air flow driving device, and the normal flow direction is recovered.
According to the embodiment of the disclosure, whether the flow channel where the airflow driving device is located is reflowed 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 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, obtaining the monitoring information of operation S210 may include: temperature information acquired 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 positions of the flow channel. And, the first temperature sensor and the second temperature sensor are respectively located at both sides of the heating element in the flow channel.
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. Wherein the first temperature sensor 302 may be arranged 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 the airflow path of the PSU power supply. The second temperature sensor 303 may be located at the air inlet of the PSU power supply and may also be located in the air flow 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, determining the current airflow direction in the flow channel in which the target airflow driving device is located based on the monitoring information in operation S220 includes: in the case where the temperature acquired by the first temperature sensor 302 is higher than the temperature acquired by the second temperature sensor 303, the current airflow direction is the direction in which the second temperature sensor 303 flows toward the first temperature sensor 302; in the case where the temperature acquired by the first temperature sensor 302 is lower than the temperature acquired by the second temperature sensor 303, the current airflow direction is the direction in which the first temperature sensor 302 flows toward 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 blows to the side where the first temperature sensor 302 is located, and thus the air flow direction is the direction from the second temperature sensor 303 to the first temperature sensor 302, i.e. the left-to-right direction in the directions shown in fig. 3A and 3B. The direction of the air flow carried by the PSU fan 301 is, for example, a left-to-right direction, and in this case, the current air flow direction in the PSU flow channel corresponds to the predetermined air flow direction corresponding to the 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 blows to the side where the second temperature sensor 303 is located, and thus the air flow 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 directions shown in fig. 3A and 3B. The direction of the air flow driven by the PSU fan 301 is, for example, from left to right, and in this case, the current air flow direction in the PSU power flow channel is inconsistent with the predetermined air flow direction corresponding to the direction of the PSU fan 301, and the PSU power flow channel is reflowed.
According to the embodiment of the disclosure, the current airflow direction is determined by the temperature sensor, so that the current airflow direction can be accurately judged, and the device is simple and low in cost.
In addition to the current airflow direction being determinable using the temperature collected by the temperature sensor, the current airflow direction may also be determined in the following manner.
According to an embodiment of the present disclosure, obtaining the monitoring information of operation S210 may include: a first operating parameter of the target airflow driving device is obtained, and a second operating parameter of an associated airflow driving device acting on the same electronic equipment as the target airflow driving device is obtained. The operation parameters may include parameters such as the rotational speed and the power of the air flow driving device.
For example, when the PSU fan and the system fan act on the same electronic device, the operation parameter of the PSU fan may be obtained as a first operation parameter, and the operation parameter of the system fan may be obtained as a second operation parameter.
According to an embodiment of the present disclosure, determining the current airflow direction in the flow channel in which 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 that the difference between the first operating parameter and the second operating parameter is greater than a certain threshold value, or may include that the first operating parameter and the second operating parameter respectively belong to respective predetermined numerical ranges.
According to embodiments of the present disclosure, a test may be performed in advance to obtain a predetermined condition. For example, it may be pre-tested that backflow may occur in the duct in which the target airflow driving device is located when the difference between the first operating parameter and the second operating parameter exceeds a large value. For another example, it may be pre-tested that the air duct in which the target airflow driving device is located will have a backflow when the first operating parameter and the second operating parameter respectively belong to what numerical ranges. For another example, a reference value of the plurality of first operation parameters may be given, and a value of the second operation parameter when the backflow occurs may be tested corresponding to each reference value of the first operation parameters, a reference correspondence table of the first operation parameters and the second operation parameters may be established, and when operation S220 is executed, the reference first operation parameters similar to the current first operation parameters may be searched from the table, and the reference second operation parameters corresponding to the reference first operation parameters may be determined, and if the current second operation parameters are greater than the reference second operation parameters, it may be considered that the backflow occurs in the air duct in which the target airflow driving device is located.
In addition, a wind pressure sensor, a wind speed sensor and other devices may be disposed in the flow channel where the target airflow driving device is located, and may measure the pressure or wind speed of airflow in a certain direction, for example, may be used to measure the airflow pressure or wind speed in the left-to-right direction in the orientations shown in fig. 3A and 3B. If the pressure or wind speed can be measured, the current airflow direction can be considered to be consistent with the measured direction, and if the pressure or wind speed cannot be measured, the current airflow direction can be considered to be inconsistent with the measured direction, and further, whether the current airflow direction is consistent with the preset airflow direction corresponding to the target airflow driving device can be judged.
According to an embodiment of the present disclosure, the rotation speed increase of the control-target airflow driving device in operation S230 may include: and controlling the target airflow driving device to increase the speed at least once, and increasing the rotating speed of the target airflow driving device by a preset value each time until the airflow direction in the flow channel is the same as the preset airflow direction.
For example, each time an additional Δpwm is given to the target airflow driving device, the rotational speed of the target airflow driving device is increased by Δn until the airflow direction in the flow passage is monitored to be the same as the predetermined airflow direction. Wherein PWM (Pulse width modulation) is pulse width modulation, which is used to control the rotation speed of the fan, and Δpwm can be set according to actual needs.
Another aspect of the disclosed embodiments also provides a control device for controlling an airflow driving device.
Fig. 4 schematically illustrates a block diagram of a control device for controlling an air flow driving device according to an embodiment of the present disclosure.
