[0002] With the rapid development of high-performance computing equipment and large data centers, the amount of heat generated is increasing exponentially. The reliability and efficiency of cooling systems have become core challenges in ensuring stable system operation. Traditional cooling technologies rely primarily on multi-fan array layouts, intelligent control algorithms, and redundant backup strategies, but they still have significant shortcomings when it comes to dealing with sudden fan failures. Summary of the Invention

[0003] The object of the present invention is to provide a method for reducing the impact of fan failure on heat dissipation, so as to solve the problems in the background technology.

[0004] A first aspect of the present invention provides a method for reducing the impact of fan failure on heat dissipation, comprising:

[0005] Obtain status information of each fan and identify the faulty fan;

[0006] The fan includes blades and baffles, and the baffles are located in front of the blades. If the baffles are perpendicular to the air outlet direction of the blades, the fan is a faulty fan.

[0007] Determining, based on the location information of the faulty fan, a fan requiring load compensation and marking the fan based on the distance from the faulty fan;

[0008] Use the step compensation method to configure the compensation air volume of each marked fan;

[0009] The rotation speed of the marked fan is adjusted according to the compensated air volume.

[0010] In this invention, by adding a baffle to the fan, gravity closes the air duct after the fan stops rotating, preventing return air and cold air supplied by other healthy fans in the equipment from escaping through the faulty fan, effectively reducing the impact of the faulty fan on the overall cooling of the equipment. Using a stepped compensation approach, the load of the remaining fans can be fully adjusted, ensuring that the cooling loss caused by the faulty fan is quickly compensated without overloading the remaining fans.

[0011] In a possible implementation, determining, based on the location information of the faulty fan, a fan requiring load compensation and marking the fan based on the distance from the faulty fan includes:

[0012] The air output of the faulty fan is obtained, an affected range radius is determined according to the air output, and all non-faulty fans within the range radius are marked with the faulty fan as the origin.

[0013] Furthermore, marking all non-faulty fans within the range radius includes:

[0014] The non-faulty fans are layered according to a preset range, and the non-faulty modules in the same layer are marked with the same symbol.

[0015] Specifically, the faulty fan can be used as the origin of the three-dimensional coordinate system, and then a three-dimensional coordinate system can be established. The distance from the remaining fans that have not failed to the faulty fan is calculated based on the three-dimensional coordinate values. This distance is numerically compared with the preset influence radius, and all non-faulty fans that are smaller than the influence radius are marked. When marking, the fans can be divided into multiple subsets according to the distance values. For example, the first subset is (0, 5], the second subset is (5, 10], and so on. All fans in each subset are marked with the same symbol.

[0016] In a possible implementation, configuring the compensation air volume of each marked fan in a stepped compensation manner includes:

[0017] According to the symbol, the compensation air volume of each level is determined, and the compensation air volume of each level is obtained in the following way:

[0018]

[0019] Among them, q n,i is the compensation air volume of the i-th fan at the n-th level, M k is the number of fans in the Kth layer, w n is the compensation weight of the nth layer, w k is the compensation weight of the kth layer, S thermal，i is the heat load coefficient of the area where the i-th fan is located, Q comp is the total compensation demand;

[0020] w n =W max ·e -λ·(n-1)

[0021] Q comp =Q failed ·η

[0022] W max is the maximum compensation weight, λ is the attenuation factor, Q failed is the air volume loss of the faulty fan, and η is the air duct loss.

[0023] In a possible implementation, adjusting the rotational speed of the marked fan according to the compensation air volume includes:

[0024] The corresponding relationship between the compensation increment and the rotational speed is applied to determine the rotational speed increase, and the real-time rotational speed of the fan is adjusted according to the rotational speed increment, wherein the corresponding relationship between the compensation increment and the rotational speed is as follows:

[0025]

[0026] ΔRPM comp，i is the speed increment, K RPM is the speed-air volume conversion coefficient, RPM nom，i is the current speed, Q nom，i is the rated compensation air volume, q n，i The current compensation air volume.

[0027] In a possible implementation manner, there are three or four baffles, each of which is a rounded rectangle, and the baffles are connected to the inner surface of the fan casing via a rotating shaft.

[0028] A second aspect of the present invention provides a system for reducing the impact of fan failure on heat dissipation, comprising:

[0029] A collection unit, used to obtain status information of each fan;

[0030] an analyzing unit, configured to identify a faulty fan, determine a fan requiring load compensation based on location information of the faulty fan, and mark the fan based on its distance from the faulty fan;

[0031] A processing unit, configured to configure the compensation air volume of each marked fan in a step compensation manner;

[0032] The rotation speed of the marked fan is adjusted according to the compensated air volume.

[0033] A third aspect of the present invention provides a computer device comprising a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the method for reducing the impact of fan failure on heat dissipation as described in the first aspect of the present invention is implemented.

[0034] A fourth aspect of the present invention provides a computer-readable storage medium storing a computer program, which, 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.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] 1. By adding a baffle to the fan, the baffle will close the air duct due to gravity when the fan stops rotating, preventing return air and cold air supplied by other non-faulty fans in the equipment from escaping from the fan of the faulty fan, effectively reducing the impact of the faulty fan on the heat dissipation of the entire equipment;

[0037] 2. The step compensation method can fully allocate the load of the remaining fans, which can quickly compensate for the heat loss caused by the faulty fan without overloading the remaining fans. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0044] 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 objects being described and do not have any order or technical meaning.

[0045] The following combination Figure 1 The method of reducing the influence of fan failure on heat dissipation of the present invention is described.

[0046] A first aspect of the present invention provides a method for reducing the impact of fan failure on heat dissipation, comprising:

[0047] S1. Obtain status information of each fan and identify the faulty fan;

[0048] like Figure 2 and Figure 3As shown, the fan includes blades 1 and baffles 2. The baffles 2 are located in front of the blades 1. There are three or four baffles, each of which is a rounded rectangle. The baffles are connected to the inner surface of the fan housing via a rotating shaft. When the blades are working normally, the baffles will appear as follows due to the effect of wind. Figure 2 The fan is in the open state shown. If the fan blades malfunction, they will move downward along the shaft under the action of gravity, thereby closing the air duct. Using three or four baffles can reduce the weight of each baffle, making it easier to close the baffle in the absence of wind. In the present invention, the baffles are made of lightweight materials, such as plastic, to facilitate closing and opening.

[0049] When identifying the status of the fan, it is only necessary to identify the position of the baffle. If the baffle is perpendicular to the air outlet direction of the fan blade, the fan is a faulty fan.

[0050] Specifically, a position sensor may be installed on the baffle, and then based on the baffle position information transmitted by the position sensor, it may be determined which fan is faulty.

[0051] In the present invention, a control center can be used to monitor the operating status of each fan, and the control center can promptly send the location information of the faulty fan to the mobile terminal of the manager, so that the manager can immediately understand the status of the faulty fan.

[0052] S2. Determine, based on the location information of the faulty fan, a fan that requires load compensation and mark it according to its distance from the faulty fan;

[0053] Specifically, the method is as follows: the air volume of the faulty fan is obtained, the affected radius is determined based on the air volume, and all non-faulty fans within the radius are marked with the faulty fan as the origin. The air volume is the total air volume to be compensated.

[0054] Marking all non-faulty fans within the range radius includes:

[0055] The non-faulty fans are layered according to a preset range, and the non-faulty modules in the same layer are marked with the same symbol.

[0056] The faulty fan can be used as the origin of the three-dimensional coordinate system, and then a three-dimensional coordinate system can be established. The distance from the remaining fans that have not failed to the faulty fan can be calculated based on the three-dimensional coordinate values. This distance is numerically compared with the preset influence radius, and all non-faulty fans that are smaller than the influence radius are marked. When marking, it can be divided into multiple subsets according to the distance value. For example, the first subset is (0,5], the second subset is (5,10], and so on. All fans in each subset are marked with the same symbol. Among them, the coordinate system can be a rectangular coordinate system or a polar coordinate system. That is, for the present invention, each subset corresponds to a layer, and each layer is marked with the same symbol to facilitate the subsequent calculation of the compensation air volume, thereby obtaining the optimal air volume compensation solution.

[0057] S3. Configure the compensation air volume of each marked fan using a step compensation method;

[0058] Use stepped compensation, meaning fans closer to the faulty fan receive a greater amount of cooling air, while fans farther away receive a smaller amount. Different air volumes should be used for different floors during air volume compensation.

[0059] When performing step compensation, the compensation strategy of space-thermal field coupling, fuzzy-PID-reinforcement learning, etc. can be adopted. In the present invention, the following methods can be used to perform step compensation:

[0060] According to the symbol, the compensation air volume of each level is determined, and the compensation air volume of each level is obtained in the following way:

[0061]

[0062] Among them, q n,i is the compensation air volume of the i-th fan at the n-th level, M k is the number of fans in the Kth layer, w n is the compensation weight of the nth layer, w k is the compensation weight of the kth layer, S thermal，i is the heat load coefficient of the area where the i-th fan is located, Q comp is the total compensation demand;

[0063] w n =W max ·e -λ·(n-1)

[0064] Q comp =Q failed ·η

[0065] W max is the maximum compensation weight, λ is the attenuation factor, Q failed is the air volume loss of the faulty fan, and η is the air duct loss.

[0066] W max The value of is usually 1.2, corresponding to 120% speed. That is, for the fan, the rated load is 1.2 times the normal working load. Exceeding this load will cause the fan to malfunction. η, as the duct loss, is related to the duct shape of the fan. If the duct shape is cylindrical, the duct loss is low. If the duct shape is cubic, the duct loss is relatively high. Its value range is 1.1 to 1.3. In the present invention, λ ranges from 0.4 to 0.6, which is obtained through experimental data analysis. The larger the level, the greater the attenuation factor value.

[0067] S4. Adjust the rotation speed of the marked fan according to the compensation air volume.

[0068] The corresponding relationship between the compensation increment and the rotational speed is applied to determine the rotational speed increase, and the real-time rotational speed of the fan is adjusted according to the rotational speed increment, wherein the corresponding relationship between the compensation increment and the rotational speed is as follows:

[0069]

[0070] ΔRPM comp，i is the speed increment, K RPM The speed-air volume conversion coefficient is usually 0.8 to 1.2, RPM nom，i is the current speed, Q nom，i is the rated compensation air volume, q n，i The current compensation air volume.

[0071] The following example illustrates the above method using a specific faulty fan scenario:

[0072] Q failed =200, η=1.2, as the parameters of the faulty fan, within the radius of influence of the faulty fan, there are two layers (two subsets) of fans, of which the first layer has 3 fans and the second layer has 5 fans. The Q of the fans in the first layer is nom，1 =50, RPM nom，1 =2000

[0073] At this time, Q comp =Q failed ·η=240, W1=1.2, w2=0.8, S thermal，1 =1.3,

[0074] S thermal，2 =1,

[0075]

[0076]

[0077] From this, we can see that the speed of the three fans on the first floor needs to be adjusted to 2000 + 1808 = 3808. The speed of the fans on the second floor can be calculated based on the calculation method of the fans on the first floor.

[0078] The step compensation method of the present invention realizes high-precision, low-jitter step compensation through multi-variable coupling and dynamic constraints, which is significantly better than traditional evenly distributed or fixed-proportion allocation methods.

[0079] In this invention, by adding a baffle to the fan, gravity closes the air duct after the fan stops rotating, preventing return air and cold air supplied by other healthy fans in the equipment from escaping through the faulty fan, effectively reducing the impact of the faulty fan on the overall cooling of the equipment. Using a stepped compensation approach, the load of the remaining fans can be fully adjusted, ensuring that the cooling loss caused by the faulty fan is quickly compensated without overloading the remaining fans.
