[0046] Embodiment two

[0047] Figure 4 A flowchart of an adjustable fan adjustment method in a fan array is provided for the second embodiment of the present application. The embodiment can be applicable to the adjustment control of the fan in the server and the effective elimination of hot spots. The method can be executed on the fan control board in any one of the servers provided in the above embodiments. As shown in the figure, the method comprises: Figure 4

[0048] S201, if it is determined that there is a hot spot according to the obtained temperature data, and the angle adjustment condition is met, forming a fan candidate list according to the position coordinates of the hot spot, the fan candidate list including at least one adjustable fan in the adjustable fan array.

[0049] In the embodiment, the angle adjustment condition can be understood as a condition for judging whether to adjust the fan angle, for example, the rotation speed of the adjustable fan closest to the hot spot has reached the maximum value, the rotation speed of all adjustable fans has reached the maximum value, the hot spot has existed for more than a preset time length, etc. The fan candidate list can be understood as a list of adjustable fans that can be adjusted in angle to eliminate the hot spot.

[0050] Specifically, the temperature data sent by the server mainboard is received, and the temperature data is analyzed to determine whether there is a position with excessively high temperature. If there is, it is determined that there is a hot spot, and the position corresponding to the temperature is determined as the position of the hot spot. Through the collection of the rotation speed of the fan, the duration of the hot spot, etc., it is determined whether the angle adjustment condition is met. If yes, the position coordinates of the hot spot are determined, each adjustable fan in the adjustable fan array is screened according to the position coordinates of the hot spot, the adjustable fan that can be used for adjustment is obtained, and the fan candidate list is formed.

[0051] When determining whether there is a hot spot, the temperature of different position coordinates is analyzed to realize the fine control of the heat area partitioning.

[0052] S202, selecting a target fan from the fan candidate list and adjusting the angle until the adjustment end condition is met.​

[0053] In the embodiment, the target fan can be specifically understood as an adjustable fan actually adjusted. The number of the target fan can be one or more, and when there are multiple target fans, the target fans can be adjusted simultaneously or sequentially. The adjustment end condition can be specifically understood as a judgment condition for judging whether to continue adjusting the fan, for example, disappearance of the hot spot, adjustment of all fans, etc.

[0054] The target fan can be selected according to an order or a position between the target fan and the hot spot. When the target fan is selected for angle adjustment, one target fan can be selected for angle adjustment first, and it is judged whether the hot spot disappears. If the hot spot disappears, it is determined that the adjustment end condition is met, and the adjustment is ended. If the hot spot does not disappear, the adjustment can be continued until the hot spot disappears. Alternatively, when the target fan is selected for angle adjustment, multiple target fans can be selected for adjustment, and then it is judged whether the hot spot disappears. If the hot spot disappears, it is determined that the adjustment end condition is met, and the adjustment is ended. After the adjustment is ended, the angle and the rotating speed of the target fan can be set according to the adjustment result.

[0055] The embodiment provides a method for adjusting a fan in an adjustable fan array, which solves the problem that a hot spot cannot be effectively cooled. A fan control board receives temperature data transmitted by a server mainboard, analyzes the temperature data, judges whether an angle adjustment condition is met when it is determined that a hot spot exists, forms a fan candidate list according to a position coordinate of the hot spot if the angle adjustment condition is met, selects a target fan from the fan candidate list for angle adjustment, and cools the hot spot, so that the hot spot is effectively eliminated. The process of adjusting and controlling the adjustable fan by the fan control board does not occupy original resources of the server, the adjustable fan is efficiently adjusted, the temperature of the server is effectively reduced, the hot spot is eliminated, and normal operation of the server is ensured.

[0056] Embodiment three

[0057] Figure 5 A flowchart of a method for adjusting a fan in an adjustable fan array is provided in the embodiment three, and the embodiment is refined on the basis of the above-mentioned embodiment two. As shown in the figure, the method comprises the following steps. Figure 5

[0058] S301, if it is determined that a hot spot exists according to the obtained temperature data, the rotating speed of each adjustable fan in the adjustable fan array is increased.

[0059] ​The temperature data is acquired and analyzed, and if there is a hot spot, the rotating speed of each adjustable fan in the adjustable fan array is adjusted, and the purpose of effective heat dissipation is achieved by increasing the rotating speed. When increasing the rotating speed, one adjustable fan can be selected for adjustment, or multiple adjustable fans can be selected for adjustment. When selecting adjustable fans for rotating speed adjustment, the closest one or multiple adjustable fans can be selected for rotating speed adjustment according to the position coordinates of the hot spot, or the farthest one or multiple adjustable fans can be selected for rotating speed adjustment. When multiple adjustable fans are selected for rotating speed adjustment, the rotating speed of each selected adjustable fan can be directly adjusted to the highest rotating speed, or the rotating speed of each selected adjustable fan can be adjusted to different rotating speeds according to the distance or position. The adjustment process can be completed at one time, or the adjustment can be performed gradually according to different steps.

[0060] During the rotating speed adjustment process, the maximum and minimum values of the rotating speed can be set to limit the rotating speed, so that the adjustable fan can work within a safe working range.

[0061] S302, if the hot spot does not disappear, it is determined that the angle adjustment condition is met.

[0062] During the rotating speed adjustment process, if the hot spot disappears, the rotating speed of each adjustable fan is set according to the rotating speed adjustment result. If the hot spot does not disappear all the time (for example, the rotating speed has been adjusted to the maximum value, and the hot spot still does not disappear at this time), the rotating speed adjustment cannot eliminate the hot spot at this time, and it is determined that the angle adjustment condition is met.

[0063] S303, the fan position coordinates of each adjustable fan in the adjustable fan array are determined.

[0064] In this embodiment, the fan position coordinates can be understood as the position coordinates of the adjustable fan. The positions of each adjustable fan are fixed after installation, and a point can be selected as the origin to determine the fan position coordinates of each adjustable fan. For example, the lower left corner of the server case is selected as the origin to determine the position coordinates of each hardware and different parts in the server case.

[0065] S304, according to the fan position coordinates and the position coordinates of the hot spot, the distance between each adjustable fan and the hot spot is calculated, and the closest adjustable fan is deleted.

[0066] The position coordinates of the hot spot can be determined according to the temperature data. When the temperature sensor is installed, the coordinates are determined according to the distance from the origin. Correspondingly, after the temperature sensor collects the temperature, the coordinates corresponding to the temperature are determined. Therefore, when the hot spot is determined, the coordinates corresponding to the temperature are determined as the position coordinates of the hot spot.

[0067] Under the condition that the position coordinates of each fan and the position coordinates of the hot spot are known, the distance between each adjustable fan and the hot spot is calculated according to the distance calculation formula, and the sizes (or distances) of each distance are compared, and the adjustable fan closest to the hot spot is removed.

[0068] S305, comparing the remaining distances, sorting each adjustable fan in order from far to near, and forming a fan candidate list.

[0069] After removing the adjustable fan closest to the hot spot, the remaining distances are compared, and each distance is sorted in order from far to near (from large to small), the adjustable fan corresponding to each distance is determined, and each adjustable fan is sorted in the above order to form a fan candidate list, that is, each adjustable fan is sorted in order from far to near according to the distance between the adjustable fan and the hot spot to form a fan candidate list.

[0070] S306, selecting an adjustable fan from the fan candidate list as a target fan for adjustment and determining whether the adjustment end condition is met.

[0071] When selecting an adjustable fan from the fan candidate list as a target fan, any one can be selected, or selection can be made according to certain rules, and after adjusting the target fan, it is determined whether the adjustment end condition is met according to the adjusted result.

[0072] As an optional embodiment of the present embodiment, the optional embodiment further optimizes the selection of an adjustable fan from the fan candidate list as a target fan for adjustment and the determination of whether the adjustment end condition is met as follows:

[0073] A1, selecting the adjustable fan farthest from the hot spot in the fan candidate list as the target fan.

[0074] When each adjustable fan in the fan candidate list is sorted in order from far to near, the first adjustable fan in the fan candidate list is the fan farthest from the hot spot, and this fan is selected as the target fan.

[0075] A2, determining a first adjustment direction according to the fan position coordinates of the target fan and the position coordinates of the hot spot, and adjusting the target fan according to a preset angle and the first adjustment direction.

[0076] In the present embodiment, the first adjustment direction can be understood as the direction of angle adjustment of the target fan, for example, left, right, or clockwise, counterclockwise, etc. The preset angle can be set by the user in advance, and the preset angle can be 3°, 5°, etc.

[0077] Specifically, the position coordinates of the fan are compared with the position coordinates of the hotspot to determine whether the hotspot is on the left side or the right side of the target fan, and then a first adjustment direction is determined. For example, if the hotspot is on the left side of the target fan, the first adjustment direction is left or counterclockwise. The target fan is controlled to rotate by a preset angle in the first adjustment direction.

[0078] A3, acquiring temperature data after a preset time, and determining whether the adjustment is effective according to the temperature data after the preset time.

[0079] In this embodiment, the preset time can be understood as a period of time set in advance for observing the change of temperature data, for example, 2s. After adjusting the target fan, the temperature data is collected after waiting for a preset time to obtain the temperature data after the preset time. The temperature data after the preset time is analyzed to determine whether the adjustment is effective. The adjustment is effective if the temperature change of the hotspot meets certain conditions, for example, the temperature decreases.

[0080] A4, if effective and the temperature of the hotspot meets the expected temperature condition, it is determined that the adjustment end condition is met.

[0081] In this embodiment, the expected temperature condition can be that the temperature is less than a temperature threshold, or the temperature change is greater than a certain threshold, etc. During the fan adjustment process, the temperature of the hotspot may change as the angle of the fan is adjusted, for example, as the angle of the target fan changes, the temperature of the hotspot decreases. When the temperature of the hotspot meets the expected temperature condition, it is determined that the adjustment end condition is met.

[0082] A5, if effective and the temperature of the hotspot does not meet the expected temperature condition, it is determined that the adjustment end condition is not met, the next adjustable fan of the target fan is taken as a new target fan, and A2 is returned to be executed.

[0083] During the adjustment of the target fan, if the temperature of the hotspot does not meet the expected temperature condition after the target fan is adjusted, the next target fan is adjusted. The next adjustable fan of the target fan in the fan candidate list is taken as a new target fan, and S307 is returned to be executed to determine the first adjustment direction, and then the adjustment is performed.

[0084] A6, if invalid, it is determined that the adjustment end condition is not met, and the adjusted target fan is repeatedly adjusted according to the preset angle and the first adjustment direction until the adjustment is effective or the angle of the target fan reaches an angle maximum value.

[0085] In this embodiment, the angle maximum value is the maximum angle that the target fan can rotate, and the angle maximum value can include the maximum values of the left and right directions, which can be represented by positive and negative values, or can be identified by setting two different identifiers. The angle maximum values of the left and right directions can be the same or different.

[0086] If the adjustment is invalid, the angle of the target fan at this time cannot effectively eliminate the hot spot, and the adjustment end condition is not met. The adjusted target fan is repeatedly adjusted according to the preset angle and the first adjustment direction, and it is judged whether the adjustment is valid. If the adjustment is valid, it can be judged whether the temperature of the hot spot meets the expected temperature condition; if each adjustment is invalid, after the angle of the target fan reaches the maximum angle, the adjustment is stopped. By setting the maximum angle, the rotation angle of the target fan is limited to prevent the fan from being damaged due to excessive rotation.

[0087] S307, if the adjustment end condition is met, the target fan works according to the adjusted angle.

[0088] If it is determined that the adjustment end condition is met, and the angle of the target fan when the adjustment end condition is met can be determined, the angle of the target fan is set as the adjustment result, and the target fan can work according to the angle in the adjustment result to effectively dissipate heat from the hot spot.

[0089] When the temperature of the hot spot meets the expected temperature condition, the angle of the target fan is set according to the adjustment result, so that the fan can work according to the angle, avoid the generation of the hot spot again, effectively dissipate heat from the server, and avoid affecting the work of the server.

[0090] S308, if the adjustment end condition is not met and each adjustable fan in the fan candidate list is adjusted as a target fan, at least two adjustable fans are selected from the fan candidate list as target fans for adjustment and it is judged whether the adjustment end condition is met.

[0091] In the process of selecting one adjustable fan for adjustment, one adjustable fan can be selected for adjustment in turn, that is, if one adjustable fan cannot eliminate the hot spot after adjustment, one adjustable fan can be selected for adjustment. If all the adjustable fans in the fan candidate list are adjusted as target fans after the angle adjustment, the adjustment end condition is still not met, at this time, at least two adjustable fans can be selected for adjustment at the same time, at least two adjustable fans are selected from the fan candidate list as target fans for adjustment, and it is judged whether the adjustment end condition is met according to the adjustment result.

[0092] As an optional embodiment of the present embodiment, the optional embodiment further optimizes the selection of at least two adjustable fans from the fan candidate list as target fans for adjustment and the judgment of whether the adjustment end condition is met as follows:

[0093] B1, at least two adjustable fans are selected from the fan candidate list as target fans and form a target fan combination.

[0094] In the embodiment, the target fan combination can be understood as a combination of multiple target fans. When selecting the target fan combination, multiple adjustable fans can be randomly selected as the target fans. Alternatively, the target fans can be selected by considering the positional relationship between the fans and the positional relationship between the fans and the hotspots. For example, the selected target fans are the fans on the same side of the hotspots, so as to avoid the occurrence of air duct turbulence and mutual offset among the multiple target fans during the operation, and to achieve the purpose of joint heat dissipation.

[0095] When selecting the multiple adjustable fans as the target fans for adjustment, the maximum number of fans can be set, and the adjustable fans can be selected as the target fans and combined into the target fan combination without exceeding the range.

[0096] B2, determining a second adjustment direction according to the fan position coordinates of each target fan and the position coordinates of the hotspots, and adjusting each target fan according to a preset angle and the corresponding second adjustment direction.

[0097] In the embodiment, the second adjustment direction can be understood as the adjustment direction of the target fan during the angle adjustment of the multiple fans, which can be left, right, clockwise, counterclockwise, etc. For each target fan, the fan position coordinates are compared with the position coordinates of the hotspots to determine whether the hotspots are on the left side or the right side of the target fan, and the second adjustment direction is determined, which has the same determination principle as the first adjustment direction. Meanwhile, each target fan is controlled to rotate a preset angle in the corresponding second adjustment direction.

[0098] It should be noted that the target fan adjusted in this step has been adjusted in the adjustment process of S306, and the target fan can continue to be adjusted on the basis of the previously adjusted angle. If the maximum angle has been reached, the adjustment can be stopped. During the adjustment process, it is determined whether the maximum angle has been reached. If the maximum angle has been reached, the adjustment is not performed.

[0099] B3, obtaining temperature data after a preset time, and determining whether the adjustment is effective according to the temperature data after the preset time.

[0100] The principle of determining whether the adjustment is effective in this step is the same as that in A3, and will not be described here.

[0101] B4, if the adjustment is effective and the temperature of the hotspots meets the expected temperature condition, it is determined that the adjustment end condition is met.

[0102] B5, if the adjustment is effective and the temperature of the hotspots does not meet the expected temperature condition, it is determined that the adjustment end condition is not met, a new target fan combination is selected from the fan candidate list, and B2 is returned for execution, wherein the target fan combination is different from the new target fan combination.

[0103] In the process of adjusting the target fans, if the temperature of the hot spot does not meet the expected temperature condition after the adjustment of the angles of the target fans, the target fan combination is reselected. A new adjustable fan is selected from the fan candidate list to form a new target fan combination, and the determination of the second adjustment direction is performed again in S307, and then the adjustment is performed. To ensure the effectiveness of the adjustment, the new target fan combination selected each time is different from the target fan combination selected before, at least one target fan is different, or multiple target fans are different.

[0104] B6, if invalid, it is determined that the adjustment end condition is not met, and the adjusted target fans are repeatedly adjusted according to the preset angle and the second adjustment direction until the adjustment is effective or the angle of each target fan reaches the maximum angle.

[0105] If the adjustment is invalid, the angle of each target fan cannot effectively eliminate the hot spot, and the adjustment end condition is not met. The adjusted target fans are repeatedly adjusted according to the preset angle and the second adjustment direction, and it is determined whether the adjustment is effective. If the adjustment is effective, it is determined whether the temperature of the hot spot meets the expected temperature condition. If the adjustment is invalid each time, the adjustment is stopped after the angle of each target fan reaches the maximum angle.

[0106] S309, if the adjustment end condition is met, the target fans are controlled to work according to the adjusted angle.

[0107] When the adjustment end condition is met, the adjustment is terminated, the angle of each target fan when the adjustment end condition is met is determined as the adjustment result, and the angle of each target fan is set to the corresponding angle in the adjustment result. The target fans can work according to the angle, and effectively dissipate heat from the hot spot.

[0108] As an optional embodiment of the embodiment, the optional embodiment further optimizes the determination of whether the adjustment is effective according to the temperature data after the preset time to:

[0109] C1, determining the temperature change of the hot spot and the temperature change of the hardware in the non-hot spot area of the server according to the temperature data after the preset time.

[0110] In the embodiment, the temperature change can be the temperature change size, or the temperature change speed, etc. According to the temperature data analysis of the temperature change of different positions, the temperature change of the hotspot is determined, which can be the temperature difference before and after the preset time according to the position coordinates of the hotspot, and then the temperature change is determined. At the same time, the temperature difference before and after the preset time of the position of the other hardware in the non-hotspot area of the server is determined, and then the temperature change is determined. When monitoring the temperature change of the hardware in the non-hotspot area of the server, the application can be selectively monitored, for example, only the temperature change of important hardware such as CPU, memory, etc. The position coordinates of the hardware to be monitored can be set in advance, and the temperature data is collected according to the position coordinates, and then the temperature change is determined.

[0111] C2, if the temperature change of the hotspot meets the temperature reduction condition and the temperature change of the hardware in the non-hotspot area meets the temperature increase condition, it is determined that the adjustment is effective.

[0112] In the embodiment, the temperature reduction condition can be that the temperature reduction value is greater than the set threshold, or the temperature reduction is to the set value, or the temperature reduction speed reaches the set minimum speed, etc. The temperature increase adjustment can be that the temperature increase value is less than the set threshold, or the temperature increase speed is less than the set speed threshold, etc.

[0113] It is determined whether the temperature change of the hotspot meets the temperature reduction adjustment, and if it meets, it is determined that the target adjustment fan can effectively eliminate the hotspot after adjustment. At the same time, it is determined whether the temperature change of the hardware in the non-hotspot area meets the temperature increase condition, and if it meets, it is determined that the target adjustment fan will not affect the heat dissipation of other positions after the adjustment angle. Therefore, if the temperature change of the hotspot meets the temperature reduction condition and the temperature change of the hardware in the non-hotspot area meets the temperature increase condition, it is determined that the adjustment is effective. When there are multiple hardware, when determining whether the adjustment is effective, the temperature change of all hardware can meet the temperature increase condition, and it is determined that the adjustment is effective.

[0114] As an optional embodiment of the embodiment, the optional embodiment further optimizes that the maximum angle is the preset maximum fan angle or the adjustable maximum angle; the adjustable maximum angle is determined according to the fan position coordinates of the target fan and the position coordinates of the hotspot.

[0115] In the embodiment, the preset maximum fan angle can be understood as a maximum angle that the fan can adjust in advance; the adjustable maximum angle is a maximum angle that the fan can adjust according to the actual fan distribution and the hot spot distribution, and the fan has a poor heat dissipation effect on the hot spot beyond the angle. In the angle adjustment process of the target fan, the maximum angle can be the preset maximum fan angle or the adjustable maximum angle. Since the target fan only needs to be adjusted in one direction when aiming at a hot spot in the actual adjustment process, only the maximum angle in one direction needs to be applied in the actual adjustment process. For example, when adjusting to the right, the preset maximum fan angle and the adjustable maximum angle are determined, the two angles are compared, and the smaller one is selected as the maximum angle.

[0116] In the adjustment process of the target fan, the adjustable maximum angle is determined according to the fan position coordinates of the target fan and the position coordinates of the hot spot. The determination method of the adjustable maximum angle of the target fan can be: determining the line connecting the target fan and the hot spot, determining the direction (for example, the vertical direction) directly opposite the target fan when installed as 0°, calculating the angle of the line connecting the target fan and the hot spot, and taking it as the adjustable maximum angle. The 0° corresponding to the direction directly opposite the target fan can also be regarded as the minimum angle of adjustment.

[0117] The embodiment of the application provides an adjustment method for adjusting the fan in the adjustable fan array, solves the problem that the hot spot cannot be effectively cooled, the fan control board receives the temperature data transmitted by the server mainboard, analyzes the temperature data, determines whether the angle adjustment condition is met when the hot spot exists, selects the target fan from the fan candidate list to adjust the angle of the target fan if the angle adjustment condition is met, and cools the hot spot, thereby effectively eliminating the hot spot. In the adjustment process, the single fan is first adjusted, and when the hot spot cannot be eliminated after the single fan is adjusted, at least two fans are adjusted at the same time, and in the adjustment process, it is judged whether the adjustment is effective to avoid invalid adjustment, effectively cool the hot spot, and greatly improve the heat dissipation capacity of the hot spot by combining the heat dissipation of the hot spot and the heat dissipation of the non-hot spot; at the same time, the fan angle is adjusted by the circulation iteration method to determine the optimal angle of the fan. The fan control board can eliminate the hot spot by a complex algorithm and will not occupy the original resources of the server BMC. When the temperature of the hot spot meets the expected temperature condition, the angle of the target fan is set according to the adjustment result, so that the fan can work at the angle, the hot spot is avoided from being generated again, the server is effectively cooled, and the working of the server is avoided from being affected.
