[0003] This application relates to the field of computers, and in particular to a fan module and a server for a server. Background Technology

[0004] In server architecture, fans, as core heat dissipation components, play a crucial role in maintaining system stability and extending hardware lifespan. Given the continuous operation requirements of servers, the hot-swappable capability of fans—allowing for convenient installation and removal without power interruption while the server is running—is particularly critical. However, current technical solutions primarily rely on manual operation. When handling fan terminals, the considerable insertion and removal force often causes operators difficulty and even makes removal challenging. Furthermore, traditional designs are often limited to the independent insertion and removal of individual fans, failing to achieve unified operation of the entire fan module. This limitation is especially pronounced when batch maintenance or replacement of fans is required, increasing maintenance complexity and time costs, posing a challenge to the efficient management and maintenance of data centers.

[0041] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0042] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0043] In this application, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this application.

[0044] To address the difficulty in installing and removing fan modules in related technologies, this embodiment provides a fan module and a server for use in servers.

[0045] As shown in Figures 1 to 13, a fan module for a server includes a fan assembly 10 and an operating unit 20. The fan assembly 10 is detachably disposed within a server chassis 30. The operating unit 20 is connected to the fan assembly 10 and is deformably disposed relative to the fan assembly 10. The operating unit 20 has a first limiting structure 211 for limiting and engaging with the server chassis 30. When the operating unit 20 is in a deformed state, the first limiting structure 211 can detach from the server chassis 30, and the fan assembly 10 can be detached. When the operating unit 20 is in a free state, the first limiting structure 211 engages with the server chassis 30, and the fan assembly 10 remains within the server chassis 30.

[0046] This embodiment features an operating unit 20 with a certain deformation capacity. Utilizing this deformability, the operating unit 20 engages with the server chassis 30, allowing it to drive the fan assembly 10 into or out of the server chassis 30. When the first limiting structure 211 of the operating unit 20 engages with the server chassis 30, the fan assembly 10 is fixed within the chassis 30, achieving overall fixation. When the operating unit 20 deforms to release the engagement between the first limiting structure 211 and the server chassis 30, it can drive the fan assembly 10 out of the chassis 30, enabling complete disassembly. This eliminates the need for tools, allowing operators to quickly and easily install or remove the fan assembly 10 from the server chassis 30, improving installation and removal efficiency, achieving tool-free installation, and reducing operator workload.

[0047] In this embodiment, the direction in which the fan assembly 10 enters the server chassis 30 is the first direction. The first limiting structure 211 is provided with a snap-fit ​​surface 2111 and an inclined surface 2112 along the first direction. The inclined surface 2112 is inclined towards the side wall of the fan assembly 10 along the first direction. When the first limiting structure 211 and the server chassis 30 are engaged, the server chassis 30 abuts against the snap-fit ​​surface 2111. Thus, during the process of installing the fan assembly 10 into the server chassis 30, the inclined surface 2112 can play a guiding role to ensure that the fan assembly 10 is smoothly installed into the server chassis 30. When the fan assembly 10 is inside the server chassis 30, the snap-fit ​​surface 2111 can play a limiting role to ensure a reliable connection between the fan assembly 10 and the server chassis 30. The first limiting structure 211 is wedge-shaped. When the fan assembly 10 is installed into the server chassis 30, the inclined surface 2112 first contacts the server chassis 30. As the fan assembly 10 is inserted deeper, the inclined surface 2112 presses against the server chassis 30, thereby providing guidance for the installation of the fan assembly 10 and making it easier for the fan assembly 10 to enter the server chassis 30. This makes the installation of the fan assembly 10 simpler and more convenient. At the same time, the inclined surface 2112 presses against the server chassis 30, causing the operating part to deform as a whole until the snap-fit ​​surface 2111 engages with the server chassis 30. The operating part 20 then returns to its free state, the fan assembly 10 is installed in place, and the snap-fit ​​surface 2111 engages with the server chassis 30, thereby ensuring a reliable connection between the fan assembly 10 and the server chassis 30. In this embodiment, the locking surface 2111 and the limiting engagement of the server chassis 30 refer to the server chassis 30 having a chassis limiting hole 1111. When the fan assembly 10 is installed in place, the first limiting structure 211 extends into the chassis limiting hole 1111, and the locking surface 2111 engages with the chassis limiting hole 1111, thereby firmly locking the fan assembly 10 inside the server chassis 30 and preventing the fan assembly 10 from moving without unlocking, thus ensuring the normal operation of the fan assembly 10. This setting method can fix the fan assembly 10 simply by locking, which is simple in structure, easy to operate, and low in cost.

[0048] It should be noted that the first direction refers to the downward direction in Figure 4, and the up and down directions mentioned in this embodiment are all the up and down directions in Figure 4.

[0049] In this embodiment, the operating part 20 includes a first segment 21 and a second segment 22 that are bent and connected. A first limiting structure 211 is located on the outer side of the first segment 21, and the second segment 22 is a free end that extends away from the fan assembly 10. This allows for both fixing the fan assembly 10 and tool-free installation of the fan assembly 10. The operating part 20 in this embodiment is configured as a plate-like structure with a certain deformation. The middle bend of the plate-like structure forms the first segment 21 and the second segment 22. The first segment 21 is fitted with the server chassis 30, and the second segment 22 provides a handhold for the operator to remove the fan assembly 10 from the server chassis 30, improving convenience. When the operator applies force to the second segment 22, it moves closer to the fan assembly 10, thereby moving the first segment 21 away from the chassis limiting hole 1111, thus releasing the limiting fit between the first segment 21 and the chassis limiting hole 1111, and allowing the fan assembly 10 to be separated from the server chassis 30.

[0050] In this embodiment, the fan assembly 10 has a mounting area on its side. The operating part 20 is connected to the inner wall of the mounting area, and a gap is formed between the two opposite sides of the operating part 20 and the mounting area to allow the first limiting structure 211 to deform, thereby facilitating the deformation of the operating part 20 for quick assembly and disassembly of the fan assembly 10. The first segment 21 is connected to the side wall of the fan assembly 10 and extends in the opposite direction of the first direction to connect with the second segment 22. The gap is located on both sides of the first segment 21 and extends in the first direction, thereby separating the first segment 21 and the side wall of the fan assembly 10 in the first direction to facilitate the deformation of the operating part 20. The first limiting structure 211 and the second segment 22 are located on the same side of the fan assembly 10, so that when the operator applies force to the second segment 22, the first segment 21 can be deformed more easily, while avoiding deformation of the side wall of the fan assembly 10 to ensure the safety of the fan assembly 10.

[0051] In one embodiment, operating parts 20 are provided at both ends of the fan assembly 10 to achieve a reliable connection of the fan assembly 10.

[0052] In this embodiment, the fan assembly 10 includes a fan frame 11 and a fan 12. The fan frame 11 has multiple receiving cavities, and the sidewall of each cavity is provided with a second limiting part 111. The fan 12 is detachably disposed within the receiving cavity, and the sidewall of the fan 12 is provided with a second limiting structure 125. The second limiting structure 125 engages with the second limiting part 111, fixing the fan 12 within the receiving cavity, thereby achieving a reliable connection and convenient assembly / disassembly between the fan 12 and the fan assembly 10. In this embodiment, the fan frame 11 has two receiving cavities arranged in a direction perpendicular to the first direction, and each cavity can accommodate one fan 12. The sidewall of the fan frame 11 away from the receiving cavity is provided with a first limiting structure 211, which can engage with the server chassis 30 for limiting, thereby fixing the fan frame 11 to the server chassis 30. The limiting method of fan 12 within the receiving cavity is similar to that of fan bracket 11 and server chassis 30. When fan 12 is placed within the receiving cavity, the second limiting structure 125 engages with the second limiting part 111, thereby ensuring reliable fixation of fan 12 to fan bracket 11. When fan 12 is removed from fan bracket 11, the second limiting structure 125 moves away from the second limiting part 111, thus unlocking fan 12 from fan bracket 11. Of course, depending on actual needs, fan bracket 11 can also be provided with three or more receiving cavities to accommodate more fans 12 to meet the server's heat dissipation requirements. When not all of the fans 12 are needed, fan bracket 11 can be used instead of fans 12 within the receiving cavity without replacing the fan bracket 11.

[0053] In this embodiment, the second limiting structure 125 is deformably configured relative to the fan frame 11. The fan 12 has an unlocking part 126 located at the entrance side of the receiving cavity. The unlocking part 126 is connected to the second limiting structure 125 and can drive the second limiting structure 125 to disengage from the second limiting part 111, thereby unlocking the fan 12 from the fan frame 11 and facilitating the removal of the fan 12 from the receiving cavity. In this embodiment, the unlocking part 126 is configured as a semi-circle, the size of which is adapted to the shape of the operator's fingers to improve human-machine compatibility. The unlocking part 126 and the second limiting structure 125 are arranged sequentially along the first direction. The unlocking part 126 and the second limiting structure 125 are located on different sides of the sidewall of the receiving cavity. The second limiting structure 125 is disposed on the surface of the sidewall of the receiving cavity away from the receiving cavity to facilitate cooperation with the second limiting part 111 outside the receiving cavity. The unlocking part 126 extends towards the center of the receiving cavity entrance side to avoid interference with other components. The side of the second limiting structure 125 facing the second limiting part 111 is called the limiting side. The second limiting structure 125 has a first side and a second side adjacent to the limiting side. The first side and the second side are arranged opposite each other, and both have deformation gaps with the sidewall of the receiving cavity, so that the second limiting structure 125 can be deformed more easily, thereby allowing the operator to easily and conveniently remove the fan 12 from the receiving cavity. Thus, when it is necessary to remove the fan 12 from the receiving cavity, the operator pulls the unlocking part 126 towards the center of the receiving cavity entrance side, thereby causing the unlocking part 126 and the second limiting structure 125 to be stretched and deformed. The unlocking part 126 drives the second limiting structure 125 to move in the same direction, thereby moving the second limiting structure 125 away from the second limiting part 111, thereby releasing the locking engagement between the second limiting structure 125 and the second limiting part 111, and allowing the fan 12 to be removed from the receiving cavity, thereby improving the convenience of fan 12 removal, realizing tool-free removal of the fan 12, and improving the efficiency of fan 12 removal.

[0054] In this embodiment, the second limiting part 111 includes a limiting hole 1111 and a limiting protrusion 1112. When the fan 12 is located inside the receiving cavity, the second limiting structure 125 can be engaged in the limiting hole 1111. Along the direction in which the fan 12 enters the receiving cavity, the limiting protrusion 1112 and the limiting hole 1111 are sequentially arranged on the side wall of the receiving cavity. The side of the limiting protrusion 1112 away from the limiting hole 1111 has an inclined guide surface, thereby enabling the second limiting part 111 to engage and limit the second limiting structure 125 while providing guidance for the installation of the fan 12. The limiting protrusion 1112 and the limiting hole 1111 are sequentially arranged along the first direction. The limiting protrusion 1112 gradually moves away from the side wall of the receiving cavity and closer to the side wall of the fan 12 along the first direction, thereby forming a guide surface inclined to the side wall of the receiving cavity. The limiting hole 1111 can be set as a rectangular hole, and its size is correspondingly set to match the second limiting structure 125, so that the second limiting structure 125 can smoothly extend into the limiting hole 1111 and be reliably limited. The second limiting structure 125 can be set as the same structure as the first limiting structure 211, which also includes a bevel and a snap-fit ​​surface. The difference is that the first limiting structure 211 is set on the side wall of the fan assembly 10, which is also the side wall of the fan bracket 11, and it cooperates with the chassis limiting part 31 for limiting. The second limiting structure 125 is set on the side wall of the fan 12 and cooperates with the second limiting part 111 for limiting. Further details are omitted. Thus, when the fan 12 is located within the receiving cavity, the limiting hole 1111 engages with the second limiting structure 125 to prevent the second limiting structure 125 from dislodging. The limiting protrusion 1112, with a flat surface at one end near the limiting hole 1111, further limits the second limiting structure 125, ensuring the fan 12 is reliably positioned within the receiving cavity. During the installation of the fan 12 into the receiving cavity, the second limiting structure 125 enters the cavity guided by the inclined surface, extending to the limiting protrusion 1112. The limiting protrusion 1112 presses against the second limiting structure 125, providing guidance for the continued installation of the fan 12. On the other hand, it also deforms the second limiting structure 125. When the second limiting mechanism extends into the limiting hole 1111, the second limiting structure 125 can quickly recover its deformation, allowing the second lower limiting structure to extend into the limiting hole 1111 and engage with it, thereby locking the fan 12 in the receiving cavity and achieving rapid installation of the fan 12.

[0055] In this embodiment, the fan assembly 10 further includes a fan partition 13, which is disposed inside the fan frame 11 and divides the interior of the fan frame 11 into multiple receiving cavities. Both the side wall of the fan frame 11 and the fan partition 13 are provided with second limiting portions 111, thereby enabling multiple fans 12 to be installed within the fan assembly 10, and ensuring that all fans 12 can be reliably connected. The fan partition 13 is a rectangular plate and is arranged parallel to the side wall of the fan frame 11 to which the operating part 20 is connected. The two ends of the fan assembly 10 connected to the operating part 20 are respectively referred to as the first end and the second end, which are arranged opposite each other. The second limiting portions 111 are provided on the side wall of each receiving cavity near the first end; therefore, one second limiting portion 111 is provided on the fan frame 11, and the other second limiting portions 111 are provided on the fan partition 13. Taking the two accommodating cavities of this embodiment as an example, one second limiting part 111 is disposed on the side wall of the fan frame 11, and another second limiting part 111 is disposed on the fan partition 13; in another embodiment with three accommodating cavities, one second limiting part 111 is disposed on the side wall of the fan frame 11, and two second limiting parts 111 are disposed on the fan partition 13, and the arrangement in other embodiments with more accommodating cavities is similar. Of course, for the convenience of disassembling and assembling the fan 12, the second limiting part 111 can also be disposed on the side wall of each accommodating cavity near the second end.

[0056] In some embodiments, when the fan 12 has stricter connection reliability requirements, a second limiting part 111 can be provided on both the side wall near the first end and the side wall near the second end of the receiving cavity. However, to avoid interference, the positions of the second limiting parts 111 need to be staggered, and the position of the second limiting structure 125 needs to be adjusted accordingly. In addition to driving the second limiting structure 125 away from the second limiting part 111 as mentioned above, the unlocking part 126 can also ensure the smooth movement and safety of the fan 12 when the operator holds the fan 12. Therefore, regardless of whether the second limiting part 111 is provided on both side walls of the receiving cavity, unlocking parts 126 can be provided on both opposite sides of the fan 12. The two unlocking parts 126 are symmetrically arranged and extend towards the center of the fan 12 to avoid interference with other components.

[0057] In this embodiment, one of the fan baffle 13 and the fan 12 has a groove 112, and the other of the fan baffle 13 and the fan 12 has a slide bar 127. The groove 112 extends along the direction in which the fan 12 enters the receiving cavity, and the slide bar 127 is located in the groove 112 and can move along the groove 112, thereby guiding the fan 12 during the assembly and disassembly process. As shown in Figures 5 and 6, the fan baffle 13 in this embodiment is provided with a groove 112, and both side walls of the fan baffle 13 facing the receiving cavity are provided with grooves 112 to cooperate with the two adjacent fans 12 respectively. A slide bar 127 is provided on the side wall of the fan 12 near the fan partition 13. Both the slide groove 112 and the slide bar 127 extend along a first direction. Thus, when the fan 12 is installed into the receiving cavity or removed from the receiving cavity, the slide bar 127 slides within the slide groove 112. The slide groove 112 and the slide bar 127 provide guidance and limitation for the fan 12, ensuring the smoothness of the fan 12 installation and removal process and preventing the fan 12 from shifting within the receiving cavity, thus ensuring the safety of the fan 12 within the receiving cavity. In one embodiment, multiple slide grooves 112 and slide bars 127 are provided to further improve the stability of the fan 12 installation and removal process. In some embodiments, the slide bar 127 and slide groove 112 may not only be provided on the fan partition 13; some slide grooves 112 may also be provided on the side wall of the fan frame 11 facing the receiving cavity, and the slide bar 127 may be provided on the side of the fan 12 near the side wall of the fan frame 11, which also serves a guiding function. Of course, a slide bar 127 can also be provided on the fan baffle 13, and a slide groove 112 can be provided on the side wall of the fan 12 near the receiving cavity, which can also achieve the purpose of guiding.

[0058] In this embodiment, the fan frame 11 has an air inlet side and an air outlet side. The air inlet side is provided with an air inlet hole 113 for the fan 12 to enter the air. The projected area of ​​the air inlet hole 113 on the air inlet side is greater than 70% of the area of ​​the air inlet side. The air outlet side is provided with an air outlet hole 116 for the fan 12 to exit the air. The projected area of ​​the air outlet hole 116 on the air outlet side is greater than 95% of the area of ​​the air outlet side. This large opening allows more of the surface area of ​​the fan 12 to be exposed outside the fan frame 11, which is conducive to the integration of the structural functions of the fan 12 and facilitates the installation of other components on the side of the fan 12. On the other hand, it helps to reduce the complexity of the mold of the fan frame 11 and save costs. As shown in Figure 5, the fan bracket 11 of this embodiment is provided with two air inlets 113 and two air outlets 116. That is, each receiving cavity is provided with one air inlet 113 and one air outlet 116, and each air inlet 113 occupies no less than 70% of the area of ​​the side wall of the receiving cavity, and each air outlet 116 occupies no less than 95% of the area of ​​the side wall of the receiving cavity. The air inlets 113 are round holes. On the air outlet side, only two adjacent edges of the receiving cavity are provided with a limiting plate to limit the position of the fan 12. The other positions on the air outlet side are all air outlets 116, which facilitates the installation of other components on the side wall of the fan 12 to realize the integration of various functions of the fan 12. Of course, depending on the number of receiving cavities, more air inlets 113 and air outlets 116 can be provided on the air inlet and air outlet sides of the fan bracket 11 to meet different heat dissipation requirements. In some embodiments, the fan bracket 11 can be provided as a simple plastic part.

[0059] As shown in Figure 3, in this embodiment, the bottom of the fan bracket 11 has a positioning hole 114. The positioning pin of the server chassis 30 passes through the positioning hole 114 to position the fan assembly 10. The positioning hole 114 is circular. When the fan bracket 11 is installed into the server chassis 30 along the first direction, the positioning pin enters the positioning hole 114, thereby achieving the correct installation of the fan bracket 11 and playing a foolproof role.

[0060] In this embodiment, the bottom of the fan bracket 11 has an observation hole 115 for observing information about the fan 12. The observation hole 115 is square and located at the position where the fan 12 is marked with information such as the fan model, so that the fan model can be identified without disassembling the fan 12, which is convenient for operation, maintenance and testing. The size, shape and position of the observation hole 115 can be adjusted according to actual needs, as long as it can identify the fan model.

[0061] In this embodiment, the fan 12 includes a fan unit 121, a fan frame 122, and a grid 123. The fan frame 122 is located within a receiving cavity and includes multiple sub-frames 1221. The sub-frames 1221 are engaged with each other via a hook structure to form a mounting cavity for accommodating the fan unit 121. The sub-frames 1221 and the fan unit 121 are connected by fasteners. The fan frame 122 has grid mounting holes, and the grid 123 is rotatably connected to the fan frame 122 through the grid mounting holes. The fan 12 has an air intake side, and the grid 123 is located on the air intake side. In this embodiment, the fan frame 122 includes two sub-frames 1221, namely a first sub-frame and a second sub-frame. Both sub-frames 1221 are cuboid in shape and are joined together to form the fan frame 122, thereby enclosing the fan unit 121 within the mounting cavity. The first sub-frame is smaller in size and has a top cover on the inlet side of the mounting cavity to prevent the fan 12 from detaching from the mounting cavity. The second sub-frame is larger in size, and the second limiting structure 125 and the slide bar 127 are both located on the second sub-frame. The second sub-frame does not have a top cover to facilitate the installation and deformation of the unlocking part 126, while also simplifying the structure, saving material costs, and reducing the complexity of the mold. Hooks and holes are respectively provided on the edges of the two sub-frames 1221 that are close to each other. The hooks extend into the holes to connect the two sub-frames 1221, enabling tool-free fixing between them and making disassembly and assembly of the sub-frames 1221 more convenient. The suction side of the fan 12, which is also the side where the fan 12 enters the air, is located on the same side as the air inlet side of the fan frame 11.

[0062] In this embodiment, the fan unit 121 is configured as a cylindrical structure. Two opposing surfaces of each sub-frame 1221 are arranged along the axial direction of the fan unit 121. Fasteners are provided at the four corners of these two surfaces to ensure a reliable connection with the fan unit 121. The fasteners can be fixed to the sub-frames 1221 using fixed protrusions; that is, fixed protrusions are provided on the surface of the sub-frames 1221, and the fasteners are fixed to these protrusions. In some embodiments, the fasteners can be plastic nails, which not only connect the fan unit 121 to the fan frame 122, but also allow the compressibility of the plastic nails to absorb some of the vibrations generated by the fan unit 121 during operation, thereby reducing the vibration problem of the fan 121.

[0063] For ease of explanation, the sub-frame 1221 closer to the suction side is referred to as the first sub-frame, and the sub-frame 1221 farther from the suction side is referred to as the second sub-frame. In this embodiment, the grid 123 is disposed within the first sub-frame and connected to the end of the first sub-frame closer to the suction side. The grid 123 is configured as a plate-like structure, connecting the two opposite surfaces of the first sub-frame and covering the suction side of the fan 12, preventing local air recirculation from affecting heat dissipation, and also preventing dust and other impurities from being drawn into the fan 12 and causing malfunctions. The grid 123 includes a long grid 123 and a short grid 123, which differ only in length. The long grid 123 is disposed near the center of the suction side, and the short grid 123 is disposed near the edge of the suction side. The short grid 123 is shorter to avoid the connection structure between the sub-frame 1221 and the fan 12. The first sub-frame is provided with long grid mounting holes and short grid mounting holes on its edge, and is equipped with a grid 123 limiting structure to ensure that the tilt direction of the grid 123 is consistent, thereby ensuring the consistency of wind direction.

[0064] As shown in Figure 7, in this embodiment, the fan frame 122 has a fan mesh structure 1223, which is located on the suction side and the blowing side of the fan 12. This not only prevents accidental insertion of fingers, ensuring personnel safety, but also makes the structure aesthetically pleasing. In some embodiments, the fan mesh structure 1223 can be set as a grid-like circular structure. It should be noted that the suction side and the blowing side of the fan 12 are arranged opposite to each other, and the suction side of the fan 12 is on the same side as the air inlet side of the fan frame 11.

[0065] As shown in Figure 9, in this embodiment, the sub-frames 1221 have a foolproof structure 1222 between them. When the sub-frames 1221 are joined together, the foolproof structures 1222 of the sub-frames 1221 engage with each other, thereby ensuring that the hooks and holes between the two sub-frames 1221 can be smoothly engaged, thus improving the assembly efficiency of the sub-frames 1221. The foolproof structure 1222 in this embodiment includes a protrusion and a groove. A protrusion is provided on the first sub-frame, and a groove is provided at a corresponding position on the second sub-frame. When assembling the sub-frames 1221, ensuring that the protrusion is located in the groove ensures that the hooks and holes can be smoothly engaged, thereby avoiding assembly errors. Of course, the positions of the protrusion and the groove can be interchanged without affecting the use effect.

[0066] In this embodiment, the fan module also has an identification element located on the outer surface of the operating part 20 away from the receiving cavity to indicate the position of the operating part 20, thereby facilitating accurate identification of the operating part 20 by the operator and enabling quick assembly and disassembly of the fan assembly 10. The identification element can be printed in blue silkscreen or other methods, as long as it is easy for the operator to identify. In some embodiments, the unlocking part 126 can also be provided with an identification element to facilitate quick identification of the unlocking part 126 by the operator, thereby improving the assembly and disassembly efficiency of the fan 12 and the fan bracket 11; using the upper surface space of the upper cover of the first sub-frame, an airflow indicator can be provided at the upper cover of the first sub-frame.

[0067] In this embodiment, the fan frame 122 has a limiting member 1224. When the fan frame 122 is installed into the receiving cavity, the limiting member 1224 abuts against the fan bracket 11 to limit the installation position of the fan frame 122, thereby preventing the fan 12 from entering the receiving cavity too deeply and causing damage to the fan terminal 124 or other components such as the board connector on the surface of the fan 12. In this embodiment, the limiting member 1224 is disposed on the first sub-frame and on the upper cover of the first sub-frame. That is, while the upper cover prevents the fan unit 121 from coming out of the mounting cavity, the edge of the upper cover extends horizontally a certain distance away from the mounting cavity. This allows the upper cover to abut against the upper surface of the side wall of the fan bracket 11 when the fan 12 is installed into the receiving cavity along the first direction and is in place, thereby forming a limiting position and preventing the fan 12 from continuing to move along the first direction.

[0068] As shown in Figure 8, in this embodiment, the fan frame 122 has a cable passage hole 1228, which connects the mounting cavity and the receiving cavity to allow cables to pass through. The cable passage hole 1228 is located on the side of the second sub-frame near the bottom of the fan bracket 11 and is located on the same side wall as the fan mesh structure 1223. The cable passage hole 1228 is located at the edge of the second sub-frame, thus forming a natural notch to facilitate the entry and exit of cables.

[0069] As shown in Figure 6, in this embodiment, the fan frame 122 has a cable management bracket 1227 to secure cables. The cable management bracket 1227 is located on the side of the second sub-frame away from the first sub-frame. The cable management bracket 1227 has a square hole for cables to pass through, and one side of the square hole has an opening to facilitate cable entry. In one embodiment, to prevent cables from coming loose, the opening faces upwards. Thus, the cable management bracket 1227 guides the cable routing for the fan 12, enabling the cables of the fan terminal 124 to travel from the fan unit 121 to the cable passage hole 1228, and then to the terminal fixing structure 1225. Furthermore, the semi-enclosed structure ensures that cables are easily inserted but not easily removed. The cable management bracket 1227 also has reinforcing ribs to improve the stability of the connection with the second sub-frame.

[0070] In this embodiment, the fan 12 further includes a fan terminal 124, which has a terminal protrusion 1241. The fan frame 122 has a terminal fixing structure 1225, which has a terminal mounting hole. When the fan terminal 124 is located in the terminal mounting hole, the terminal protrusion 1241 is engaged with the terminal mounting hole. As shown in FIG7, the terminal fixing structure 1225 and the cable management frame 1227 are disposed on the same side of the fan frame 122, and the cable management frame 1227 and the terminal fixing structure 1225 are arranged along a first direction. A terminal fixing hole is provided in the middle of the terminal fixing structure 1225. The terminal fixing hole has a large cross-section segment and a small cross-section segment, which are arranged sequentially along the first direction. Multiple recesses are provided on the periphery of the small cross-section segment. As shown in FIG10, the fan terminal 124 has a large end and a small end, and multiple terminal protrusions 1241 are provided on the side of the small end. Thus, when installing the fan terminal 124, it is installed along the first direction; when the fan terminal 124 is located in the terminal mounting hole, the larger end is located in the larger cross-sectional section, the smaller end is located in the smaller cross-sectional section, and the terminal protrusion 1241 is located in the recess, thereby limiting the position of the fan terminal 124 and fixing its position to prevent lateral movement. In some embodiments, a fan terminal 124 with a smaller insertion and removal force can be customized to make insertion and removal of the fan terminal 124 simpler, thereby facilitating insertion and removal by the operator.

[0071] As shown in Figures 2 and 4, in this embodiment, the terminal fixing structure 1225 also has an elastic element 1226. The elastic element 1226 is connected to the fan frame 122. When the fan terminal 124 is inserted into the terminal mounting hole, the elastic element 1226 abuts against the fan terminal 124 and prevents the fan terminal 124 from coming out of the terminal mounting hole. The elastic element 1226 is located on the upper side of the terminal fixing structure 1225 and is connected to the side wall of the fan frame 122. The elastic element 1226 is inclined relative to the side wall of the fan frame 122. The upper end of the elastic element 1226 is connected to the fan frame 122, and the lower end is away from the fan frame 122 and close to and above the terminal mounting hole. When the fan terminal 124 is installed from above the terminal mounting structure, the fan terminal 124 approaches the elastic member 1226 along the first direction and abuts against the side of the elastic member 1226 away from the fan frame 122, pressing the elastic member 1226 close to the fan frame 122. When the fan terminal 124 is installed into the terminal mounting hole, the lower end of the elastic member 1226 returns to the top of the terminal mounting hole, thereby limiting the fan terminal 124 and fixing it, preventing the fan terminal 124 from coming out from above the terminal mounting hole. When removing the fan terminal 124 from the terminal mounting hole, simply move the elastic member 1226 so that its lower end moves closer to the fan frame 122, and then move the fan terminal 124 in the opposite direction of the first direction to remove it. In this way, the terminal fixing structure 1225 fixes the fan terminal 124, which is convenient to install and does not require additional locking parts to fix the fan terminal 124, thus saving costs. In some embodiments, the elastic element 1226 may be a spring-type structure.

[0072] In this embodiment, the fan assembly 10 further includes a wind deflector disposed within the gap between the fan frame 11 and the server chassis 30 and blocking the gap to prevent air backflow. In some embodiments, the wind deflector may be wind-blocking foam disposed around the fan frame 11 to seal the gap between the fan frame 11 and the server chassis 30.

[0073] In this embodiment, the fan assembly 10 further includes a honeycomb element 1229, which includes a plurality of honeycomb mesh-like small holes. The honeycomb element 1229 is connected to the fan frame 122 and covers the air intake side of the fan frame 122. That is, the honeycomb element 1229 covers the entire air inlet 113 of the fan frame 11, thereby enabling better noise absorption when the fan unit 121 rotates at a high speed, thereby reducing the noise of the fan assembly 10.

[0074] The fan assembly 10 in this embodiment also includes a light guide column for indicating the status of the fan 12. The light guide column is disposed on the fan frame 122 and electrically connected to the fan unit 121, thereby utilizing the light transmission of the light guide column to detect the operating status of the fan 12 in real time and display the faulty fan 12, making it easy to identify. In some embodiments, an indicator light can also be provided on the fan board of the server, with the light guide column electrically connected to the fan board, thereby further quickly identifying the faulty fan 12 through the color change of the indicator light.

[0075] In this embodiment, the fan 12 also includes an extension component. The extension component is detachably connected to the end of the fan unit 121 and can be mated with the fan frame 122, thereby enabling the fan frame 122 to adapt to different specifications of fans 12 and improving the adaptability of the fan assembly 10. The fan unit 121 is generally configured as a cylindrical structure, so the extension component is also configured as a cylindrical structure with the same diameter as the fan unit 121. When the axial length of the fan unit 121 is small and cannot be adapted to the fan frame 122, the fan unit 121 is connected and fixed to the extension component, and then the assembly of the fan unit 121 and the extension component is placed into the mounting cavity to realize the use of the fan frame 122 with different specifications of fan units 121. This allows multiple specifications of fans 12 to share the same specification of fan frame 122, thereby enabling the fan frame 122 to adapt to more usage scenarios and making replacement convenient.

[0076] This application also provides a server, including a server chassis 30 and the aforementioned fan module for the server. The fan module is located inside the server chassis 30. The server chassis 30 includes a chassis limiting part 31. When the fan module is connected to the server chassis 30, the first limiting structure 211 of the fan module engages with the chassis limiting part 31 and prevents the fan module from detaching from the server chassis 30, thereby ensuring the stability of the fan module during server operation and avoiding a decrease in heat dissipation efficiency due to loosening of the fan module, thereby improving the stability and reliability of the server. As shown in Figures 11 and 13, the server chassis 30 of this embodiment is provided with a chassis limiting plate. The chassis limiting plate is located on one side of the server chassis 30, parallel to and spaced apart from one side wall of the server chassis 30. The chassis limiting part 31 is provided on the chassis limiting plate. The chassis limiting part 31 can be set as a rectangular chassis limiting hole 1111. When the fan assembly 10 is located inside the server chassis 30, the first limiting structure 211 is located in the chassis limiting hole 1111 and cooperates with the chassis limiting hole 1111 to fix the fan assembly 10 stably inside the server chassis 30.

[0077] In this embodiment, the server also includes a motherboard, and a first wiring gap is provided between the fan bracket 11 of the fan module and the motherboard for cable routing, thereby facilitating cable routing inside the server chassis 30. That is, along the first direction, the fan module and the motherboard are arranged sequentially in this embodiment, and cables for the motherboard, fan 12, or other devices can pass between the motherboard and the fan module to facilitate wiring between the devices.

[0078] In this embodiment, the side wall of the server chassis 30 and the fan module have a second wiring gap 32 for cable routing, thereby providing wiring space for the cables inside the server. In this embodiment, the first limiting structure 211 of the fan module is in a limiting engagement with the chassis limiting part 31. Therefore, the gap between the side wall of the server chassis 30 and the fan module is also the gap between the side wall of the server chassis 30 and the chassis limiting plate. This space is the second wiring gap 32.

[0079] In this embodiment, the server chassis 30 also includes a fixing member 40. Multiple fan modules are present, and the fixing member 40 is located between two adjacent fan modules and engages with the first limiting structure 211 of the fan module to achieve a reliable connection between the fan module and the server chassis 30. Based on the size differences between the fan modules and the server chassis 30, as well as heat dissipation requirements, the server in this embodiment has two fan modules. As shown in Figure 1, the fixing member 40 is a cuboid shape composed of four plate-like structures, including three side plates and a top plate. Two opposing sides are parallel to the side walls of the server chassis 30. The fixing member 40 can be positioned between two fan modules. The two opposing sides of the fixing member 40 act as two chassis limiting plates, connecting to the two fan modules respectively. Chassis limiting parts 31 are respectively provided on the two opposing sides of the fixing member 40, which are fixed with the first limiting structure 211, enabling tool-free assembly and disassembly of the fixing member 40 and the fan assembly 10. In this way, one end of the fan module is connected to the chassis limiting plate near the side wall of the server chassis 30, and the other end of the fan module is connected to one side of the fixing member 40, thereby making the fan module securely fixed inside the server chassis 30. Of course, the number of fan modules can be adjusted according to factors such as heat dissipation requirements and space inside the server chassis 30. Only one set of fan modules can be set, with both ends connected to the chassis limiting plate near the side wall of the server chassis 30; or more fan modules can be set, with fan modules at both ends connected to the fixing member 40 or other structures on the server chassis 30 equipped with chassis limiting plates. The connection method for the fan modules near the side wall of the server chassis 30 is similar to that when two sets of fan modules are set, and will not be described again. In some embodiments, the surface of the fixing member 40 can be screen-printed with information such as the serial number of the fan unit 121 for easy identification by operators.

[0080] In this embodiment, the server also includes a cover mounted on the server chassis 30. The fastener 40 has a cable routing channel 42 for facilitating cable routing within the server chassis 30. In this embodiment, the space between the three side panels and the top panel of the fastener 40 serves as the cable routing channel 42. The side panels away from the top panel have flanges for easy connection to the bottom of the server chassis 30. Through holes can be provided between the flanges and the side panels to facilitate cable routing. These through holes can serve as cable inlets or outlets, allowing cables to enter and exit the cable routing channel 42. This fully utilizes the space between the two fan modules, resulting in a compact structure that optimizes the internal layout of the server chassis 30.

[0081] As shown in Figures 12 and 13, the fastener 40 in this embodiment has a locking structure 41. The fastener 40 is locked to the cover via the locking structure 41, thereby improving the security and reliability of the server. In this embodiment, the locking structure 41 is located on the top plate of the fastener 40 and extends away from the top plate. The locking structure 41 is cylindrical and can be fixed to the top plate by riveting. When the server is working, the locking structure 41 locks to the cover, ensuring that the server will not be accidentally opened during normal operation. When maintenance is required, staff can release the locking structure 41 and the cover to open the cover.

[0082] In this embodiment, the server chassis 30 further includes a detection element 50, which is connected to the fixing element 40 and can detect and record the number of times the cover is opened. In this embodiment, the detection element 50 is also disposed on the top plate of the fixing element 40 and extends away from the top plate of the fixing element 40, and can also be configured as a cylindrical pin. The detection element 50 can be configured as an intrusion switch to accurately record the number of times the cover is opened.

[0083] It should be noted that "multiple" in the above embodiments refers to at least two.

[0084] As can be seen from the above description, the embodiments of this application achieve the following technical effects:

[0086] 2. By setting the operating part to have a certain deformation, and by using the deformable characteristics of the operating part to cooperate with the server chassis limit, the operating part can drive the fan assembly to be installed into the server chassis or removed from the server chassis.

[0087] 3. No tools are required, allowing operators to quickly and easily install or remove the fan assembly from the server chassis. This improves the efficiency of fan assembly installation and removal, enabling tool-free installation and reducing the workload of operators.
