If the adjustment is invalid, the hot spot cannot be effectively eliminated by the angle of each target fan, and the adjustment ending condition is not met. Repeatedly adjusting each adjusted target fan according to a preset angle and a second adjusting direction, judging whether the adjustment is effective, and if the adjustment is effective, judging whether the temperature of the hot spot meets an expected temperature condition; and if the adjustment is invalid every time, stopping adjusting after the angle of each target fan reaches the maximum angle value.
And S309, if the adjustment ending condition is met, controlling each target fan to work according to the adjusted angle.
When the adjustment finishing condition is met, stopping adjustment, determining the angle of each target fan when the adjustment finishing condition is met, taking the angle as an adjustment result, setting the angle of each target fan as a corresponding angle in the adjustment result, and enabling each target fan to work according to the angle to effectively radiate the hot spot.
As an optional embodiment of this embodiment, the optional embodiment further optimizes the judgment on whether the adjustment is effective according to the temperature data after the preset time as follows:
and C1, determining the temperature change of the hot spot and the temperature change of hardware in a non-hot spot area in the server according to the temperature data after the preset time.
In this embodiment, the temperature change may be a temperature change magnitude, a temperature change speed, or the like. And analyzing the temperature changes of different positions according to the temperature data to determine the temperature change of the hot spot, wherein the temperature change can be determined by determining the temperature difference before and after a preset time according to the position coordinates of the hot spot. Meanwhile, the temperature difference of the positions of other hardware in the non-hot spot area in the server before and after the preset time is determined, and then the temperature change is determined. According to the method and the device, when the temperature change of the hardware in the non-hot spot area in the server is monitored, the temperature change of important hardware, such as a CPU (central processing unit), a memory and the like, can be selectively monitored. The position coordinates of hardware to be monitored can be preset, temperature data can be collected according to the position coordinates, and then temperature change can be determined.
And C2, if the temperature change of the hot spot meets the temperature reduction condition and the temperature change of the hardware in the non-hot spot area meets the temperature increase condition, determining that the adjustment is effective.
In the present embodiment, the temperature decrease condition may be that the value of the temperature decrease is larger than a set threshold value, or that the temperature decreases to a set value, or that the speed of the temperature decrease reaches a set minimum speed, or the like. The temperature increase adjustment may be that the value of the temperature increase is less than a set threshold, or that the speed of the temperature increase is less than a set speed threshold, etc.
Judging whether the temperature change of the hot spot meets the temperature reduction regulation or not, and if so, determining that the hot spot can be effectively eliminated after the target regulating fan is regulated; meanwhile, whether the temperature change of the hardware in the non-hot spot area meets the temperature increase condition is judged, if yes, the target adjusting fan is determined to be not influencing the heat dissipation of other positions after the angle is adjusted, and therefore if the temperature change of the hot spot meets the temperature decrease condition and the temperature change of the hardware in the non-hot spot area meets the temperature increase condition, the adjustment is determined to be effective. When the hardware is multiple, and whether the adjustment is effective is judged, the temperature change of all the hardware can meet the temperature rise condition, and the adjustment is determined to be effective.
As an optional embodiment of this embodiment, the optional embodiment further optimizes the maximum angle to be a preset maximum fan angle or an 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 hot spot.

In the angle adjustment process of the target fan, the maximum angle may be a preset maximum fan angle or an adjustable maximum angle. In the actual adjusting process of the target fan, when aiming at a hot spot, the target fan only needs to be adjusted towards one direction, so that the maximum angle value in one direction only needs to be applied in the actual adjusting process. For example, when adjusting to the right, the preset maximum fan angle and the adjustable maximum angle are determined, the sizes of the two angles are compared, and the smaller one is selected as the maximum value of the angle.
And in the adjusting process of the target fan, determining the adjustable maximum angle according to the fan position coordinate of the target fan and the position coordinate of the hot spot. The adjustable maximum angle of the target fan may be determined by: determining a connecting line between the target fan and the hot spot, determining the direction (for example, the vertical direction) opposite to the target fan when the target fan is installed as 0 degree, and calculating the angle of the connecting line between the target fan and the hot spot as the adjustable maximum angle. The 0 ° corresponding to the direction in which the target fan is facing can also be regarded as the minimum value of the angle of adjustment.
The embodiment of the invention provides an adjusting method of a fan in an adjustable fan array, which solves the problem that heat can not be effectively dissipated, a fan control board receives temperature data transmitted by a server mainboard, analyzes the temperature data, judges whether an angle adjusting condition is met or not when the hot spot exists, if the angle adjusting condition is met, a fan candidate list is formed according to position coordinates of the hot spot, a target fan is selected from the fan candidate list for angle adjustment, the hot spot is dissipated, and the hot spot is effectively eliminated. The method comprises the steps that firstly, a single fan is adjusted in the adjusting process, when the hot spot cannot be eliminated after the single fan is adjusted, at least two fans are adjusted at the same time, in the adjusting process, whether the adjustment is effective or not is judged, invalid adjustment is avoided, the hot spot is effectively radiated, the force of a plurality of fans is integrated, the hot spot radiation and non-hot spot radiation are considered, and the heat radiation capability of the hot spot is greatly improved; meanwhile, the fan angle is adjusted in a circulating iteration mode, and the optimal fan angle is determined. The fan control board can eliminate hot spots through a complex algorithm, and cannot occupy the original resources of the server BMC. When the hot spot temperature meets the expected temperature condition, the angle of the target fan is set according to the adjusting result, the fan can work according to the angle, the hot spot is prevented from being generated again, the heat of the server is effectively dissipated, and the work of the server is prevented from being influenced.
