[0012] like Figure 1-Figure 2 As shown, in one embodiment, a water cooling fan intelligent control method is proposed, the method comprising: S1: After the water cooling fan is started, the water mist distribution in the set area is monitored by a visual device; S2: determining the direction in which the fan is about to shake its head, and determining the wind force influence area of ​​the fan in the set area according to the direction; S3: Obtaining the current basic water mist distribution and the preset standard water mist distribution in the wind-affected area; S4: Get the current fan power and water pump power; S5: The basic water mist distribution, the fan power and the water pump power are used as the initial conditions for the water mist simulation under the operation of the water cooling fan; S6: Perform water mist simulation with the initial conditions to determine whether the basic water mist distribution can be transformed into the standard water mist distribution; S7: If yes, use the fan power as the target fan power and the water pump power as the target water pump power; S8: If not, adjust the fan power and / or water pump power, and execute steps S5 to S8 until the target fan power and target water pump power are obtained; S9: When the fan shakes its head toward this direction, the water cooling fan is controlled to operate at the target fan power and the target water pump power; S10: Repeat steps S2 to S9 until the water cooling fan stops running.

[0013] In this embodiment, the method is executed in a computer device, which can be an independent physical server or terminal, or a server cluster composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud servers, cloud databases, cloud storage and CDN; the water-cooling fan is controlled by the computer device, and the water-cooling fan includes an oscillating motor for driving the fan to shake its head, a fan motor for driving the fan blades to rotate, and a water pump for pumping water to the blades; under the control of the computer device, the water pump pumps water to the blades, and the blades rotate to blow out water to form water mist, and the fan shakes its head driven by the oscillating motor so that the blown water mist is distributed within a set range; the visual device can be one or more high-definition cameras connected to the computer device and facing a set area, which can collect the distribution of water mist within the set range.

[0014] In this embodiment, if Figure 3 As shown, the set area can be a space area on the ground with a set size of rectangle (circle, square or other shape) in front of the water cooling fan; the wind influence area is the area where the wind of the fan can blow when the fan is in a certain direction, and the shape of the wind influence area can be regarded as a column area with the fan surface as the cross section; In this embodiment, the standard water mist distribution is a preset water mist distribution with high uniformity, so that the water mist distribution in a certain area is transformed into the standard water mist distribution, that is, the water mist distribution in the area reaches the uniformity of the standard water mist distribution; the water-cooling fan shakes its head at a certain rate during the water cooling process of the set area, and the terminal equipment monitors the water mist distribution in the set area in real time through a visual device. Before the water-cooling fan is about to turn to any direction, water mist simulation can be performed based on the existing water mist distribution in that direction to determine the fan power (power of the fan motor) and water pump power that can transform the existing water mist distribution into the standard water mist distribution, and then when the water-cooling fan shakes its head to that direction, the water-cooling fan is controlled to operate with the fan power and water pump power, that is, the fan power and water pump power of the water-cooling fan can be adaptively adjusted in real time to make the water mist distribution at each position in the set area tend to the standard water mist distribution, thereby ensuring the uniformity of water cooling in the set area.

[0015] As a preferred embodiment, the set area is a preset spatial area that needs to be water-cooled, and the water mist distribution is the water mist density at each position in the area; the monitoring of the water mist distribution in the set area by the visual device includes: Divide the set area into several sub-areas of the same size; identifying each sub-region in a visual image captured by a visual device; Image analysis is performed on each visual image to determine the water mist density in each sub-area, and then the water mist distribution in the set area is obtained.

[0016] In this embodiment, the sub-area can be a set volume (e.g. 1 dm 2 ) spatial region; by determining the number of droplets in each sub-region, the water mist density in the sub-region can be determined, and then the water mist density in the entire set area, that is, the water mist distribution, can be determined; in this embodiment, the visual devices at multiple positions can respectively capture images from multiple angles. For each captured image, the terminal device can identify each sub-region in the image, and use the existing target detection algorithm to determine the number of droplets in each sub-region, and then calculate the water mist density of each sub-region.

[0017] As a preferred embodiment, water mist simulation is performed with the initial conditions to determine whether the basic water mist distribution can be transformed into the standard water mist distribution, including: Retrieve a water cooling fan model, and direct the fan surface of the water cooling fan model toward a simulation area corresponding to the wind influence area; Determine the water mist density of each simulated sub-area in the simulated area according to the basic water mist distribution, and generate initial simulated fog droplets according to the water mist density of the simulated sub-area; The water-cooling fan model is mobilized to simulate the operation for a set time with the fan power and water pump power of the initial conditions, so that the simulated mist droplets blown out by the water-cooling fan model are mixed with the initial simulated mist droplets to determine the simulated water mist distribution; It is determined whether the simulated water mist distribution is the same as the standard water mist distribution. If so, the basic water mist distribution can be transformed into the standard water mist distribution. Otherwise, the basic water mist distribution cannot be transformed into the standard water mist distribution.

[0018] In this embodiment, water mist simulation is performed by ANSYS Fluent software. Before the simulation, the model of the currently controlled water-cooling fan is called out from the preset model library, and a set area corresponding to the actual set area is delineated. The direction of the model is adjusted so that the fan direction of the water-cooling fan model determines the simulation area corresponding to the wind influence area. The corresponding parameters corresponding to the initial conditions are input into the software for simulation, thereby generating simulated droplets. The distribution of the simulated droplets is used to standardize the distribution of the actual droplets to determine the fan power and the water pump power. In order to be able to fully adjust the water mist distribution in each direction (the angle difference between directions can be 10°, 15° or other degrees), the water-cooling fan can be set to stay for a set time after shaking its head to a certain direction, such as 2 seconds, 3 seconds or other time.

[0019] As a preferred embodiment, a first adjustment range and a first minimum power interval are preset for the fan power, and a second adjustment range and a second minimum power interval are preset for the water pump power; Adjusting the fan power and / or water pump power, executing steps S5 to S8 until the target fan power and target water pump power are obtained includes: S81: taking the minimum value of the first adjustment range as the fan power; S82: taking the minimum value of the second adjustment range as the water pump power; S83: Execute steps S5 to S6; S84: If the basic water mist distribution can be transformed into the standard water mist distribution, the fan power is used as the target fan power, and the water pump power is used as the target water pump power; S85: If the basic water mist distribution cannot be transformed into the standard water mist distribution, the water pump power is added to the second minimum power interval to obtain a new water pump power, and steps S83 to S85 are executed until the target fan power and the target water pump power are obtained, or the new water pump power exceeds the maximum value of the second adjustment range; S86: If the new water pump power exceeds the maximum value of the second adjustment range, add the first minimum power interval to the fan power to obtain a new fan power, and execute steps S82 to S86 until the target fan power and target water pump power are obtained, or the new fan power exceeds the maximum value of the first adjustment range.

[0020] In this embodiment, the first adjustment range can be 20W~120W, the first minimum power interval can be 5W, the second adjustment range can be 500W~1500W, and the second power interval can be 50W; in this embodiment, ergodic simulation is realized, that is, water mist simulation is carried out under each optional combination of fan power and water pump power, thereby ensuring the comprehensiveness of the simulation.

[0021] As a preferred embodiment, if the target fan power and the target water pump power are still not obtained after the new fan power exceeds the maximum value of the first adjustment range, the method further includes: Calculate the basic deviation between the basic water mist distribution and the standard water mist distribution; Calculate the simulated deviation between the simulated water mist distribution and the standard water mist distribution for each simulation; Calculate the ratio of the simulated deviation to the basic deviation for each simulation; Screen out the simulations whose proportions are smaller than the set value; Identify the current basic power parameters of the water cooling fan, where the basic power parameters include the current fan power and water pump power of the water cooling fan; For each simulation selected, a first difference between the simulated power parameter of the simulation and the basic power parameter is calculated, and a second difference between the simulated deviation degree of the simulation and the basic deviation degree is calculated; Determine the deviation reduction efficiency according to the first difference and the second difference of the simulation, wherein the deviation reduction efficiency represents the degree of deviation reduction corresponding to the unit parameter adjustment; The simulated fan power and water pump power with the highest corresponding deviation reduction efficiency are determined, and the fan power is used as the target fan power and the water pump power is used as the target water pump power.

[0022] The deviation between any water mist distribution and the standard water mist distribution is calculated by the following formula:

[0023] Where D is the deviation between the water mist distribution and the standard water mist distribution, is the absolute value of the difference between the water mist density corresponding to the water mist distribution in the i-th sub-area and the water mist density corresponding to the standard water mist distribution, n is the number of sub-areas in the set area, is the deviation adjustment factor.

[0024] The basic parameter power includes the basic fan power and the basic water pump power, and the simulated parameter power includes the simulated fan power and the simulated water pump power; The first difference is calculated by the following formula:

[0025] in, is the first difference, is the absolute value of the difference between the simulated fan power and the basic fan power, is the absolute value of the difference between the simulated water pump power and the basic water pump power, for The adjustment factor, for The adjustment factor of The second difference is calculated by the following formula:

[0026] in, is the absolute value of the difference between the simulated deviation and the basic deviation, for The adjustment factor of The deviation reduction efficiency is calculated by the following formula:

[0027] in, To reduce the efficiency of deviation.

[0028] In this embodiment, It can be 10, or other values; users can determine the specific value based on the difficulty of adjusting the two powers. , , according to , The order of magnitude is predetermined and is not limited here. After the ergodic simulation, it is still possible that the target fan power and the target water pump power cannot be obtained. At this time, the simulations with a corresponding ratio less than the set value (which can be 20%, 30%) are screened out, that is, the simulation results close to the standard water mist distribution can be screened out, and the fan power and water pump power corresponding to a simulation are determined as the target power. Since the simulation results of the screened simulations are relatively close to the target results, in this embodiment, the simulation with the highest deviation reduction efficiency is selected from the screened simulations, which can reduce the amount of parameter adjustment of the fan and the water pump, thereby ensuring the efficiency of the adjustment and timely adjustment to the target parameters to ensure the water cooling effect.

[0029] like Figure 4 As shown, in one embodiment, a water-cooling fan intelligent control device is provided, and a module in the water-cooling fan intelligent control device is used to execute the water-cooling fan intelligent control method, including: A monitoring module is used to monitor the water mist distribution in a set area through a visual device after the water cooling fan is started; A first processing module is used to determine the direction in which the fan is about to shake its head, and determine the wind force influence area of ​​the fan in a set area according to the direction; The first acquisition module is used to acquire the current basic water mist distribution and the preset standard water mist distribution in the wind-affected area; The second acquisition module is used to obtain the current fan power and water pump power; A second processing module is used to use the basic water mist distribution, the fan power and the water pump power as initial conditions for water mist simulation under the operation of the water cooling fan; The third processing module is used to perform water mist simulation based on the initial conditions to determine whether the basic water mist distribution can be transformed into the standard water mist distribution; A fourth processing module, configured to, if yes, use the fan power as the target fan power and the water pump power as the target water pump power; A first repetitive module, for adjusting the fan power and / or the water pump power if no, and executing steps S5 to S8 until the target fan power and the target water pump power are obtained; A fifth processing module, configured to control the water cooling fan to operate at a target fan power and a target water pump power when the fan shakes its head toward the direction; The second repetitive module is used to repeatedly execute steps S2 to S9 until the water cooling fan stops running.

[0032] In this embodiment, the computer equipment cooperates with the visual device and the water-cooling fan to execute the intelligent control method of the water-cooling fan. Before the water-cooling fan is about to turn to any direction, a water mist simulation can be performed based on the existing water mist distribution in that direction to determine the fan power (the power of the fan motor) and the water pump power that can transform the existing water mist distribution into the standard water mist distribution.
