[0050] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0051] The embodiment of the present application provides a fan device 1, Figure 1 A schematic diagram of the structure of a fan device provided in this application is shown in FIG. Figure 1 As shown, the fan device 1 comprises:

[0052] A first fan group 10 includes a plurality of first fans 100, and the plurality of first fans 100 are arranged along a first direction to cool the temperature of the first component;

[0053] The control unit 11 is configured to send a first instruction to the sliding module 13 when it is determined that the second fan 12 meets the start-up condition;

[0054] The sliding module 13 includes a fixing structure 130 connected to the second fan 12, and the fixing structure 130 can slide along a first direction, and is used to move the second fan 12 to a first position when receiving a first instruction;

[0055] The second fan 12 is fixedly connected to the sliding module 13 via the fixing structure 130 and is used for cooling the temperature of the first component.

[0056] A fan device 1 provided in an embodiment of the present application is suitable for use in a scenario where the system temperature is cooled.

[0057] In some embodiments, when the first fan group 10 in the fan device 1 is cooling the temperature of the first component, the control unit 11 can continuously detect whether the second fan 12 meets the start-up conditions. When it is detected that the second fan 12 meets the start-up conditions, the control unit 11 sends a first instruction to the sliding module 13. When receiving the first instruction, the sliding module 13 moves the second fan 12 to the first position through the fixed structure 130 connected to the second fan 12. At this time, the second fan 12 can cool the temperature of the first component at the first position.

[0058] It should be noted that the first component may be a component that generates heat during operation. In order to ensure the stable operation of these components and extend the service life of these components, they usually need to be cooled by a fan. For example, the first component may be a graphics processing unit (GPU), a central processing unit (CPU), or a control cabinet equipped with various electronic devices and electrical components; the specific first component can be determined based on actual conditions, and the embodiments of the present application are not specifically limited here.

[0059] In an optional implementation of the present application, the start condition is that the first fan 100 fails, and the control unit 11 is further configured to determine that the first fan 100 fails when it is detected that the fan speed of the first fan 100 is less than a second threshold value.

[0060] In some embodiments, the control unit 11 determines that the second fan 12 meets the start-up condition when detecting that the first fan 100 in the first fan group 10 fails.

[0061] Exemplarily, the first fan group 10 may include one or more first fans 100. Taking the example of the first fan group including 4 first fans 100, the control unit 11 can determine that the second fan 12 meets the starting condition when it detects that one first fan 100 in the first fan group 10 fails. The control unit 11 can also determine that the second fan 12 meets the starting condition when it detects that a preset number of first fans 100 in the first fan group 10 fail. The specific preset number can be set according to actual conditions, and the embodiments of the present application are not specifically limited here.

[0062] In some embodiments, when the control unit 11 detects that a first fan 100 among the plurality of first fans 100 has a fan speed less than a second threshold value, it determines that the first fan 100 fails, thereby determining that the second fan 12 meets the start-up condition.

[0063] Exemplarily, taking the example that the first fan group includes four first fans 100, the control unit 11 can obtain the fan speed of the four first fans 100 in the first fan group 10 through the fan sensor, and when it is detected that the fan speed of a first fan 100 among the four first fans 100 is less than the second threshold value, it is determined that the first fan 100 has a fault, and thus the second fan 12 meets the start-up condition; the specific second threshold value can be set according to actual conditions, and the embodiment of the present application does not make specific limitations here.

[0064] In an optional implementation of the present application, the sliding module 13 is a first sliding module, wherein:

[0065] A first sliding module, used for moving the second fan 12 back and forth along a first direction;

[0066] The control unit 11 is further configured to send a first instruction to the first sliding module when it is determined that a first fan 100 among the plurality of first fans 100 fails;

[0067] The first sliding module is further used to move the second fan 12 to a first position corresponding to the first fan 100 upon receiving the first instruction, so that the second fan 12 replaces the first fan 100 to cool the temperature of the first component.

[0068] In some embodiments, when the control unit 11 detects that the fan speed of a first fan 100 among multiple first fans 100 is less than a second threshold value, it determines that the first fan 100 has failed. At this time, the control unit 11 sends a first instruction to the first sliding module. Upon receiving the first instruction, the first sliding module moves the second fan 12 along the first direction to a first position corresponding to the first fan 100. As a result, the second fan 12 can replace the first fan 100 to cool the temperature of the first component.

[0069] In some embodiments, when the first fan group 10 cools the temperature of the first component, the second fan 12 may not be turned on temporarily. When the first sliding module moves the second fan 12 to the first position corresponding to the first fan 100, the second fan 12 is turned on. At this time, the faulty first fan 100 may be turned off, and the second fan 12 and the first fan 100 that is not faulty in the first fan group 10 may be used together to cool the temperature of the first component. Alternatively, the faulty first fan 100 may be kept on, and the second fan 12 and the first fan group 10 may be used together to cool the temperature of the first component. The specific cooling method for the first component may be selected according to actual conditions, and the embodiments of the present application are not specifically limited here.

[0070] In an optional embodiment of the present application, the first sliding module includes one or more of the following:

[0071] A first driving unit, configured to drive the second fan 12 upon receiving a first instruction;

[0072] A first guide rail, arranged along a first direction, for fixing the first sliding module and the first fan assembly;

[0073] A first gear, used for the first sliding module to move back and forth along a first direction on the first guide rail;

[0074] The first fixing structure includes a rotatable connection with the first gear, fixes the first driving unit, and fixes the fixing structure 130 .

[0075] For example, reference Figure 2 , the first fan group 10 includes fan 1, fan 2, fan 3 and fan 4, and the second fan 12 is fan 5. Assuming that fan 3 is currently determined to be faulty, at this time, fan 5 can be moved back and forth along the first direction to the position corresponding to fan 3, so that fan 5 replaces fan 3 to cool the first component. The first component is Figure 2Peripheral Component Interconnect Express (PCIE) / GPU, and CPU / Dual-inline-Memory-Modules (DIMM).

[0076] For example, reference Figure 3 , a schematic diagram of an exemplary first sliding module is given, referring to Figure 4 , a schematic diagram of the composition structure of an exemplary fan device 1 is given. Figure 4 In the figure, the first sliding module 40 specifically includes a first driving unit 41, a first guide rail 42, a first gear 43 and a first fixed structure 44. When receiving the first instruction, the first driving unit 41 drives the second fan 12 to move back and forth along the first direction based on the first guide rail 42 until the second fan 12 is moved to the first position corresponding to the first fan 100 where the fault occurs, for example, the first position corresponding to the third first fan 100 counted from left to right along the first direction.

[0077] Exemplary, reference Figure 5 , a schematic diagram of an exemplary composition structure of the first sliding module is given, such as Figure 5 As shown, it can be seen more clearly that the first sliding module 40 specifically includes a first driving unit 41, a first guide rail 42 and a first gear 43; wherein the first driving unit 41 can be an engine, the first gear 43 can be a branch line gear, and the first guide rail 42 can be a frame. The specific first sliding module can be determined according to actual conditions, and the embodiments of the present application do not make specific limitations here.

[0078] Exemplary, reference Figure 6 , an exemplary application scenario 1 of the fan device 1 is given. Figure 6 In the embodiment, the fan device 1 cools down the first component 61 in the chassis 60, and Figure 4 In the event that the first fan 100 in the fan device 1 fails, the second fan 42 is moved to the first position so that the second fan 42 replaces the failed first fan 100 and continues to cool the first component 61 .

[0079] In an optional implementation manner of the present application, the start condition is that the temperature of the first component is greater than the first threshold value, and the sliding module is the second sliding module; wherein:

[0080] The second sliding module is further used to move the second fan along the first direction and a second direction different from the first direction;

[0081] The control unit is further configured to determine a first area with the highest temperature in the first component and send a first instruction to the second sliding module when the second fan meets the start-up condition;

[0082] The second sliding module is also used to move the second fan to a second position relative to the first area when receiving the first instruction, so that the second fan and the first fan group can cool the temperature of the first component simultaneously.

[0083] In some embodiments, reference Figure 7 The fan device 1 can also be used in a rack-level scenario. When the control unit 11 detects that the temperature of the rack is greater than the first threshold value, it determines the first area with the highest temperature in the rack and sends a first instruction to the second sliding module. When the second sliding module receives the first instruction, it moves the second fan 12 to a second position relative to the first area, so that the second fan and the first fan group can cool the temperature of the rack simultaneously.

[0084] In some embodiments, when the first fan group 10 cools the temperature of the first component, the second fan 12 may be temporarily turned off. When the second sliding module moves the second fan 12 to a second position relative to the first area, the second fan 12 is turned on. At this time, the first fan group 10 and the second fan 12 can be used together to cool the temperature of the first component. The specific cooling method for the first component can be selected according to actual conditions, and the embodiments of the present application are not specifically limited here.

[0085] For example, reference Figure 8 , an exemplary application scenario 2 of the fan device 1 is given, in Figure 8 In the fan device 1 ( Figure 8 The rack is cooled by a fan (not shown) and the temperature of the rack is monitored at the same time. After monitoring that the temperature of the rack is greater than a first threshold value, a first area with the highest temperature in the rack can be determined by a temperature sensor, and then the second fan 2 is moved along a first direction and a second direction different from the first direction to a second position corresponding to the first area by a second sliding module 80. Thus, the second fan 2 can cool the first area in a targeted manner, thereby reducing the temperature of the entire rack.

[0086] In an optional embodiment of the present application, the second sliding module includes one or more of the following:

[0087] A second driving unit, configured to drive a second fan upon receiving the first instruction;

[0088] A second guide rail, used to fix the second sliding module to the first fan assembly;

[0089] A second gear, used for the second sliding module to move back and forth on the second guide rail along a first direction and a second direction different from the first direction;

[0090] The second fixing structure includes a rotatable connection with the second gear, fixing the second driving unit, and fixing the fixing structure.

[0091] In some embodiments, when the control unit 11 detects that the temperature of the first component is greater than the first threshold value, it determines the first area with the highest temperature in the first component and sends a first instruction to the second driving unit. When the second driving unit receives the first instruction, it drives the second fan second sliding module to move the second fan 2 back and forth on the second guide rail along the first direction and the second direction different from the first direction until the second fan 2 is moved to the second position corresponding to the first area, so that the second fan 2 cools down the first area.

[0092] In an optional implementation of the present application, the fan device 1 further includes an early warning unit, wherein:

[0093] an early warning unit, configured to continuously output first early warning information in response to a failure of the first fan 100 and / or a temperature of the first component being greater than a first threshold value when the first fan 100 fails and / or the temperature of the first component is greater than a first threshold value;

[0094] The early warning unit is further configured to stop outputting the first early warning information when the first fan 100 is replaced with a third fan and / or the temperature of the first component is not greater than a first threshold value.

[0095] In some embodiments, when the early warning unit determines that the first fan has failed, it continuously outputs a first early warning message about the failure of the first fan through sound or text messages to remind the user that the first fan needs to be replaced. The first early warning message is stopped until the user replaces the failed first fan with a new third fan.

[0096] In some embodiments, when the warning unit determines that the temperature of the first component is greater than the first threshold value, the warning unit continuously outputs a first warning message regarding the temperature of the first component being greater than the first threshold value through a sound or text message, to remind the user that measures need to be taken to cool the first component, until the user reduces the temperature of the first component to less than the first threshold value, and then stops outputting the first warning message.

[0097] In an optional embodiment of the present application, the control unit 11 is further configured to switch the current state of the second fan 2 from an off state to an on state to cool the temperature of the first component when it is determined that the second fan 2 moves to the first position.

[0098] In some embodiments, the second fan 2 can be understood as a backup fan. In order to avoid wasting resources, the second fan 2 can be turned off when the first fan group is cooling the first component. Only after the second fan 2 is moved to the first position, the second fan 2 is turned on to cool the first component.
