[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] It will be understood that when used in this specification and the appended claims, the terms “comprises” and “comprising” indicate the presence of described features, integers, steps, operations, elements and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof.

[0024] It should also be understood that the terms used in this utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in this utility model specification and the appended claims, the singular forms "a", "an" and "the" are intended to include plural forms unless the context clearly indicates otherwise.

[0025] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0026] See also Figures 1 to 3 The specific embodiment of the utility model discloses a fan assembly anti-foolproof structure, including: a fan assembly 1 and a mounting shell 2, the fan assembly 1 is installed on the mounting shell 2, a first anti-foolproof component 11 is provided on the fan assembly 1, and a second anti-foolproof component 21 is provided on the mounting shell 2, the first anti-foolproof component 11 includes an anti-foolproof notch 111 and an anti-foolproof code 112, the second anti-foolproof component 21 is an anti-foolproof positioning column 211, after the anti-foolproof positioning column 211 cooperates with the anti-foolproof notch 111, the anti-foolproof code 112 is identified to achieve comprehensive anti-foolproofing of the fan assembly 1.

[0027] Specifically, conventional axial fans can be assembled by rotating the fan to any angle when the inlet and outlet surfaces are correctly installed. However, when the front and back of the two fans are installed reversed, correction can only be achieved by visually identifying the direction of the fan blades. Therefore, it is difficult to achieve 100% correct installation, which poses a significant risk of heat dissipation. In this embodiment, the cooperation of the anti-foolproofing positioning column 211 and the anti-foolproofing notch 111 achieves primary anti-foolproofing, while the IT system recognizes the anti-foolproofing code 112 to achieve secondary anti-foolproofing. The combination of the two allows for full-scenario anti-foolproofing of the fan assembly 1.

[0028] like Figure 1 and Figure 3 As shown, the mounting housing 2 includes a front housing 22 and a rear housing 23 . The fan assembly 1 is detachably mounted on the rear housing 23 , and the front housing 22 is snap-connected to the fan assembly 1 .

[0029] Specifically, in this embodiment, the front housing 22 and rear housing 23 are made of metal and have appropriate vents or openings to ensure air circulation. Place the fan assembly 1 in the predetermined position on the rear housing 23, ensuring that the air inlet of the fan assembly 1 matches the design of the rear housing 23. Depending on the design of the rear housing 23, securely attach the fan assembly 1 to the rear housing 23 using screws, clips, or other removable mounting methods. If the rear housing 23 is designed with a clip slot, align the clip portion of the fan assembly 1 with the slot and press down until you hear it snap into place. Then, align the front housing 22 with the rear housing 23 with the fan assembly 1 already installed, ensuring that the vents on the front housing 22 align with the air outlet of the fan assembly 1 to ensure smooth air flow. Depending on the design of the front and rear housings 22, 23, secure the front housing 22 to the rear housing 23 using clips, slots, or other mounting methods. If the front housing 22 is designed with a clip, align it with the clip slot on the rear housing 23 and press down until the clip is fully locked.

[0030] It is understandable that in other embodiments, the front shell 22 and the rear shell 23 may also be made of plastic or other types of materials, and the specific configuration may be based on actual conditions.

[0031] like Figures 1 to 3 As shown, the fan assembly 1 includes at least two fans 12, each fan 12 is provided with an air outlet surface 121 and an air inlet surface 122, and each of the air outlet surface 121 and the air inlet surface 122 is provided with at least one anti-foolproof notch 111, and the number of anti-foolproof notches 111 corresponds to the number of anti-foolproof positioning columns 211.

[0032] Specifically, in this embodiment, the number of fans 12 is two. In other embodiments, the number of fans 12 can be set according to the specific heat dissipation requirements of the server.

[0033] like Figure 1As shown, the foolproof positioning column 211 is located on the rear shell 23, the air inlet surface 122 is arranged close to the rear shell 23, and correct installation is achieved through the positioning and foolproofing effect of the foolproof positioning column 211 on the foolproof notch 111.

[0034] Specifically, to ensure the correct airflow direction of the fan assembly 1, the air inlet surface 122 must be positioned close to the rear housing 23. Furthermore, the positions of the anti-mock notches 111 and anti-mock positioning posts 211 must also match. During installation of the fan assembly 1, ensure that the anti-mock notch 111 of each fan 12 is aligned with and inserted into the corresponding anti-mock positioning post 211 to ensure proper installation of the fan assembly 1.

[0035] like Figures 1 to 3 As shown, each fan 12 is provided with an anti-fool code 112 , and the anti-fool code 112 is located on the side of the fan 12 .

[0036] Specifically, in this embodiment, the foolproof code 112 is a QR code label sticker that is affixed to the fan 12. Each QR code contains specific information, such as the model, specifications, serial number, etc. of the fan 12. This information is unique and is used to identify and distinguish different fans 12. During the assembly process of the server fan assembly 1, a scanning device capable of recognizing QR codes (such as a barcode scanner, a smartphone, etc.) is used. These devices capture the QR code image through a camera and decode it. By scanning the QR code on the fan 12 and verifying its information, it can be ensured that each fan 12 is of the correct model and specifications, thereby avoiding malfunctions or damage caused by incorrect installation.

[0037] The fool-proof structure provided in this embodiment is specifically divided into four fool-proof situations: (1) The barcode labels are exposed at the top and bottom of the fan assembly 1, the barcode can be collected normally, and the fool-proof notch 111 is in the correct position, the front and rear shells are assembled normally, and the two fans 12 are installed correctly at this time; (2) The upper fan 12 is correct and the lower fan 12 is installed upside down. At this time, the barcode label at the bottom of the fan 12 module is not exposed, and fool-proofing is achieved by collecting the barcode; (3) The upper fan 12 is installed upside down and the lower fan 12 is correct. At this time, the barcode label at the top of the fan 12 module is not exposed, and fool-proofing is achieved by collecting the barcode; (4) Both the upper and lower fans 12 are installed upside down. At this time, the barcode label on the fan 12 module is exposed, and fool-proofing cannot be achieved by collecting the barcode, but the fool-proof notch 111 is in the wrong position, and the front and rear shells cannot be assembled at this time.

[0038] like Figure 1 As shown, a handle 231 is further provided on the outer side of the rear shell 23 .

[0039] Specifically, the design of the handle 231 allows the user to easily grasp and lift the entire fan assembly 1 without having to find other carrying tools or methods. This is especially important when the fan assembly 1 needs to be moved or reinstalled, and can greatly improve work efficiency.

[0040] In an optional embodiment, a fan vibration damping pad (not shown in the figure) is provided on the fan 12.

[0041] Specifically, the fan 12 generates vibrations during operation, and the fan vibration damping pad can absorb and reduce these vibrations, thereby reducing noise. Secondly, the fan vibration damping pad can improve the stability of the fan assembly 1, preventing displacement or damage caused by vibration, thereby helping to extend the service life of the fan assembly 1.

[0042] like Figure 1 As shown, the fan assembly 1 is provided with at least two fan terminals 13 on one side of the anti-foolproof code 112 , and terminal fixing members 221 are respectively provided on the inner side of the front shell 22 , and the fan terminals 13 are installed on the terminal fixing members 221 .

[0043] Specifically, in the present embodiment, there are two fan terminals 13 on the fan assembly 1, which are used to connect to an external circuit to realize the power supply and control signal transmission of the fan 12. The anti-foolproof code 112 is provided on the side of the fan 12, adjacent to the fan terminal 13, and is used to provide a visual or mechanical identification mark during the installation process to ensure that the fan assembly 1 is correctly installed. Terminal fixing members 221 are respectively provided on the inner side of the front shell 22 to fix the fan terminals 13 to ensure that the fan terminals 13 do not loosen or fall off due to vibration during the operation of the fan 12. In the present embodiment, the terminal fixing member 221 can be a protrusion, a groove or a special card slot, which matches the shape of the fan terminal 13 to achieve a firm fixation.

[0044] like Figure 1 As shown, a dustproof net 232 is further provided on the side of the rear shell 23 away from the air inlet surface 122 .

[0045] Specifically, the dust screen 232's primary function is to prevent external dust and impurities from entering the interior of the fan assembly 1. By installing the dust screen 232 on the rear housing 23, the fan 12 can be effectively prevented from getting stuck due to dust intrusion during operation, extending the lifespan of the fan 12. Furthermore, the dust screen 232 allows air circulation while trapping dust, ensuring the fan 12's heat dissipation function while preventing dust from affecting heat dissipation efficiency.

[0046] The utility model also provides a server heat dissipation device, comprising the fan assembly fool-proof structure as described in the above embodiment.

[0047] Specifically, the server cooling device employs the fan assembly foolproof structure described in the above embodiment, comprising a fan assembly 1 and a mounting housing 2, with the fan assembly 1 mounted within the mounting housing 2. Through this embodiment, the server cooling device not only provides efficient heat dissipation but also ensures the correct installation and stable operation of the fan assembly 1, thereby improving the stability and reliability of the server.

[0048] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
