[0002] With the rapid development of high-performance computing devices and large data centers, the heat generated inside them is increasing exponentially, making the reliability and efficiency of the cooling system a core challenge to ensure stable system operation. Traditional cooling technologies mainly rely on multi-fan array layouts, intelligent control algorithms, and redundancy backup strategies, but they still have significant shortcomings in dealing with sudden fan failures. Summary of the Invention

[0003] The purpose of this invention is to provide a method for reducing the impact of fan failure on heat dissipation, thereby solving the problems in the background art.

[0004] A first aspect of the present invention provides a method for reducing the impact of fan failure on heat dissipation, comprising: Obtain the status information of each fan and identify the faulty fan; The fan includes fan blades and baffles. The baffles are located in front of the fan blades. If the baffles are perpendicular to the airflow direction of the fan blades, the fan is a faulty fan. Based on the location information of the faulty fan, determine the fan that needs load compensation and mark it according to the distance from the faulty fan; The compensation air volume of each marked fan is configured using a stepped compensation method; Adjust the speed of the marked fan according to the compensated air volume.

[0005] In this invention, by adding baffles to the fan, the baffles close the airflow due to gravity after the fan stops rotating, preventing return air and cool air supplied by other non-faulty fans from flowing out from the faulty fan, effectively reducing the impact of the faulty fan on the overall heat dissipation of the equipment. The stepped compensation method can fully allocate the load of the remaining fans, ensuring rapid compensation for the heat loss caused by the faulty fan without overloading the other fans.

[0006] In one possible implementation, determining the fan requiring load compensation based on the location information of the faulty fan and marking it according to the distance from the faulty fan includes: Obtain the airflow of the faulty fan, determine the radius of the affected area based on the airflow, and mark all non-faulty fans within the radius of the affected area, using the faulty fan as the origin.

[0007] Furthermore, marking all non-faulty fans within the said radius includes: The non-faulty fans are divided into layers according to a preset range, and non-faulty modules in the same layer are marked with the same symbol.

[0008] Specifically, the faulty fan can be used as the origin of a three-dimensional coordinate system. The distances of the remaining non-faulty fans to the faulty fan are calculated based on their coordinates. This distance is then compared to a preset radius of influence. All non-faulty fans with distances smaller than the radius are marked. The marking can be divided into multiple subsets based on distance values; for example, the first subset could be (0, 5], the second subset (5, 10], and so on. All fans within each subset are marked using the same symbol.

[0009] In one possible implementation, configuring the compensated airflow of each marked fan using a stepped compensation method includes: Based on the symbols, the compensation air volume for each level is determined, and the compensation air volume for each level is obtained in the following manner:

[0010] in, This is the compensation airflow for the i-th fan in the n-th level. The number of fans on the Kth floor. The compensation weights for the nth layer are... The compensation weights for the k-th layer are... Let i be the heat load coefficient of the area where the i-th fan is located. Total compensation requirements; = = W max To maximize the compensation weight, As the attenuation factor, The airflow loss is due to the faulty fan. This is due to air duct losses.

[0011] In one possible implementation, adjusting the speed of the marked fan according to the compensated airflow includes: By applying the aforementioned relationship between compensated airflow and rotational speed, the rotational speed increment is determined, and the real-time rotational speed of the fan is adjusted according to the rotational speed increment. The relationship between the compensated airflow and rotational speed is as follows:

[0012] For speed increments, This is the speed-to-airflow conversion coefficient. The current rotational speed, For the rated compensation air volume, This is the current compensation air volume.

[0013] In one possible implementation, the baffle is three or four pieces, each of which is a rounded rectangle, and the baffle is connected to the inner surface of the fan housing via a rotating shaft.

[0014] A second aspect of the present invention provides a system for reducing the impact of fan failure on heat dissipation, comprising: The data acquisition unit is used to obtain the status information of each fan; An analysis unit is used to identify faulty fans, determine the fans that need load compensation based on the location information of the faulty fans, and mark them according to the distance from the faulty fans; The processing unit is used to configure the compensated air volume of each marked fan using a stepped compensation method; Adjust the speed of the marked fan according to the compensated air volume.

[0015] A third aspect of the present invention provides a computer device including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor, when executing the computer program, implements the method for reducing the impact of fan failure on heat dissipation as described in the first aspect of the present invention.

[0016] A fourth aspect of the present invention provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the method for reducing the impact of fan failure on heat dissipation as described in the first aspect of the present invention.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. By adding baffles to the fan, the baffles will close the air duct due to gravity after the fan stops rotating, preventing the return air and the cool air supplied by other non-faulty fans in the equipment from flowing out from the fan of the faulty fan, effectively reducing the impact of the faulty fan on the heat dissipation of the entire equipment. 2.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0020] It should be noted that the serial numbers assigned to the components in the embodiments of the present invention, such as "first" and "second", are only used to distinguish the described objects and have no sequential or technical meaning.

[0021] The following is combined with Figure 1 The method of the present invention for reducing the impact of fan failure on heat dissipation is described.

[0022] A first aspect of the present invention provides a method for reducing the impact of fan failure on heat dissipation, comprising: S1. Obtain the status information of each fan and identify the faulty fan; like Figure 2 and Figure 3 As shown, the fan includes fan blades 1 and baffles 2. The baffles 2 are located in front of the fan blades 1. There are three or four baffles, each with rounded corners. The baffles are connected to the inner surface of the fan housing via a rotating shaft. When the fan blades are working normally, the baffles will appear as follows due to the wind: Figure 2 The fan is in the open state shown. However, if the fan blades malfunction, they will move downwards along the axis of rotation under the influence of gravity, thus closing the air duct. Using three or four baffles can reduce the weight of each baffle, making it easier for the baffles to close in the absence of wind. In this invention, the baffles are made of lightweight materials, such as plastic, to facilitate opening and closing.

[0023] When identifying the status of a fan, it is only necessary to identify the position of the baffle. If the baffle is perpendicular to the airflow direction of the fan blades, then the fan is a faulty fan. Specifically, a position sensor can be installed on the baffle plate, and then the baffle plate position information transmitted by the position sensor can be used to determine which fan is malfunctioning.

[0024] In this invention, a control center can monitor the operating status of each fan, and the control center can promptly send the location information of a faulty fan to the mobile terminal of the management personnel. Management personnel can then immediately understand the status of the faulty fan.

[0025] S2. Based on the location information of the faulty fan, determine the fan that needs load compensation and mark it according to the distance from the faulty fan; The specific method is as follows: Obtain the airflow of the faulty fan; determine the radius of the affected area based on the airflow; and mark all non-faulty fans within the radius, using the faulty fan as the origin. The airflow is the total airflow to be compensated for subsequently.

[0026] The step of marking all non-faulty fans within the radius of the range includes: The non-faulty fans are divided into layers according to a preset range, and non-faulty modules in the same layer are marked with the same symbol.

[0027] The faulty fan can be used as the origin of a three-dimensional coordinate system. The distances from the faulty fan to the remaining non-faulty fans are calculated based on their coordinates. This distance is then compared to a preset radius of influence; all non-faulty fans with distances smaller than this radius are marked. The marking can be done by dividing the system into multiple subsets based on distance values. For example, the first subset could be (0, 5], the second subset (5, 10], and so on. All fans within each subset are marked with the same symbol. The coordinate system can be either Cartesian or polar. In other words, each subset corresponds to a layer, and each layer is marked with the same symbol, facilitating subsequent calculations of the compensation airflow to obtain the optimal airflow compensation scheme.

[0028] S3. The compensation air volume of each marked fan is configured using a stepped compensation method; A tiered compensation method is used, meaning that the closer a fan is to the faulty fan, the greater the amount of cold air it receives as compensation, and the farther away it is, the less cold air it receives. Different airflow rates need to be used for different floors when performing airflow compensation.

[0029] Step compensation can be performed using spatial-thermal field coupling compensation strategies, fuzzy-PID-reinforcement learning, and other methods. In this invention, step compensation can be performed in the following manner: Based on the symbols, the compensation air volume for each level is determined, and the compensation air volume for each level is obtained in the following manner:

[0030] in, This is the compensation airflow for the i-th fan in the n-th level. The number of fans on the Kth floor. The compensation weights for the nth layer are... The compensation weights for the k-th layer are... Let i be the heat load coefficient of the area where the i-th fan is located. Total compensation requirements; = = W max To maximize the compensation weight, As the attenuation factor, The airflow loss is due to the faulty fan. This is due to air duct losses.

[0031] The value is usually taken as 1.2, corresponding to 120% speed. That is, for a fan, the rated load is 1.2 times the normal operating load. Exceeding this load will cause the fan to malfunction. Airflow loss is related to the shape of the fan duct. If the duct is cylindrical, the airflow loss is low; if the duct is cubic, the airflow loss is relatively high. Its value ranges from 1.1 to 1.3. In this invention, the value range is 0.4 to 0.6, which is obtained through experimental data analysis. The larger the level, the larger the attenuation factor value.

[0032] S4. Adjust the speed of the marked fan according to the compensated air volume.

[0033] By applying the aforementioned relationship between compensated airflow and rotational speed, the rotational speed increment is determined, and the real-time rotational speed of the fan is adjusted according to the rotational speed increment. The relationship between the compensated airflow and rotational speed is as follows:

[0034] For speed increments, This is the speed-to-airflow conversion factor, typically ranging from 0.8 to 1.2. The current rotational speed, For the rated compensation air volume, This is the current compensation air volume.

[0035] The above method will be illustrated with examples of specific fan malfunctions: by =200, =1.2, used as a parameter for the faulty fan. Within the radius of influence of the faulty fan, there are two layers (two subsets) of fans, with the first layer having 3 fans and the second layer having 5 fans. The fans in the first layer... =50, =2000 at this time, = =240, W1=1.2, w2=0.8, =1.3, =1, = =45.2 =1 =1808 Therefore, the speed of the three fans on the first layer needs to be adjusted to 2000 + 1808 = 3808. The speed of the fans on the second layer can be calculated using the same method as the fans on the first layer.

[0036] The step compensation method of this invention achieves high-precision, low-chatter step compensation through multivariate coupling and dynamic constraints, which is significantly better than the traditional amortized or fixed-ratio allocation method.

[0037] In this invention, by adding baffles to the fan, the baffles close the airflow due to gravity after the fan stops rotating, preventing return air and cool air supplied by other non-faulty fans from flowing out from the faulty fan, effectively reducing the impact of the faulty fan on the overall heat dissipation of the equipment. The stepped compensation method can fully allocate the load of the remaining fans, ensuring rapid compensation for the heat loss caused by the faulty fan without overloading the other fans.
