Description

Technical Field

[0002] In the server architecture, fans, as core heat dissipation components, play an important role in maintaining system stability and extending hardware life. In view of the continuous operation requirements of the server, the hot-swappable feature of the fan, that is, the ability to easily install and remove the fan while the server remains in operation and without powering off, is particularly critical. However, existing technical solutions mainly rely on manual operation. When handling the fan terminals, due to the large plug-in and pull-out force, operators often feel laborious and even face the problem of difficulty in unplugging. In addition, traditional designs are often limited to the independent plugging and unplugging of a single fan, and cannot achieve unified operation of the entire fan module. This limitation is particularly obvious when batch maintenance or replacement of fans is required, which increases the complexity and time cost of maintenance, and poses a challenge to the efficient management and maintenance of data centers.

DETAILED DESCRIPTION

[0039] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0040] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0041] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0042] In order to solve the problem of difficulty in installing and removing a fan module in the related art, this embodiment provides a fan module for a server and a server.

[0043] like Figures 1 to 13A fan module for a server is shown, comprising a fan assembly 10 and an operating part 20, wherein the fan assembly 10 is detachably arranged in a server chassis 30; the operating part 20 is connected to the fan assembly 10, and the operating part 20 is deformably arranged relative to the fan assembly 10, and the operating part 20 has a first limiting structure 211 for limiting cooperation with the server chassis 30, when the operating part 20 is in a deformed state, the first limiting structure 211 can be separated from the server chassis 30, and the fan assembly 10 can be disassembled, and when the operating part 20 is in a free state, the first limiting structure 211 is limited and cooperated with the server chassis 30, and the fan assembly 10 is maintained in the server chassis 30.

[0044] In this embodiment, the operating part 20 is set to have a certain deformation amount, and the operating part 20 is limited and matched with the server chassis 30 by virtue of the deformable characteristics of the operating part 20, so that the operating part 20 can drive the fan assembly 10 to be installed inside the server chassis 30 or removed from the server chassis 30. Specifically, when the first limiting structure 211 of the operating part 20 is limited and matched with the server chassis 30, the fan assembly 10 is fixed in the server chassis 30, thereby realizing the overall fixation of the fan assembly 10; when the operating part 20 releases the limiting match between the first limiting structure 211 and the server chassis 30 through deformation, the operating part 20 can drive the fan assembly 10 to be separated from the server chassis 30, thereby realizing the overall removal of the fan assembly 10. In this way, without the help of tools, the operator can quickly and conveniently install the fan assembly 10 inside the server chassis 30 or remove it from the server chassis 30, which is conducive to improving the disassembly and assembly efficiency of the fan assembly 10, realizing the tool-free installation of the fan assembly 10, and at the same time can reduce the labor intensity of the operator.

[0045] In this embodiment, the direction in which the fan assembly 10 enters the server chassis 30 is the first direction, and the first limiting structure 211 is sequentially provided with a snap-fit ​​surface 2111 and a slope 2112 along the first direction, and the slope 2112 is inclined along the first direction toward the direction close to the side wall of the fan assembly 10, and when the first limiting structure 211 and the server chassis 30 are limitedly matched, the server chassis 30 abuts against the snap-fit ​​surface 2111, so that during the process of installing the fan assembly 10 into the server chassis 30, the slope 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 located 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. Specifically, the first limiting structure 211 is wedge-shaped. When the fan assembly 10 is installed inside the server chassis 30, the inclined surface 2112 first contacts the server chassis 30, and as the fan assembly 10 goes deeper, the inclined surface 2112 squeezes the server chassis 30, thereby providing a guide for the installation of the fan assembly 10, allowing the fan assembly 10 to enter the server chassis 30 more smoothly, thereby making the installation of the fan assembly 10 simpler and more convenient. At the same time, the inclined surface 2112 squeezes the server chassis 30 to deform the operating part as a whole until the snap-fit ​​surface 2111 is limitedly engaged with the server chassis 30, the operating part 20 returns to a free state, the fan assembly 10 is installed in place, and the snap-fit ​​surface 2111 is snap-fitted with the server chassis 30, thereby ensuring a reliable connection between the fan assembly 10 and the server chassis 30. The limiting cooperation between the snap-fit ​​surface 2111 and the server chassis 30 of this embodiment refers to the server chassis 30 being provided with 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 snap-fit ​​surface 2111 and the chassis limiting hole 1111 are snap-fitted and limited, thereby firmly locking the fan assembly 10 in the server chassis 30 to prevent the fan assembly 10 from moving without being unlocked, thereby ensuring the normal operation of the fan assembly 10. This setting method can fix the fan assembly 10 by relying solely on the snap-fit ​​limit, has a simple structure, is easy to operate, and has a low cost.

[0046] It should be noted that the first direction refers to Figure 4 The up and down directions in this embodiment are Figure 4 The up and down directions in .

[0047] In this embodiment, the operating portion 20 includes a first section 21 and a second section 22 that are bent and connected, a first limiting structure 211 is located on the outer side of the first section 21, and the second section 22 is a free end and extends in a direction away from the fan assembly 10, so that the fan assembly 10 can be fixed and installed without tools. Specifically, the operating portion 20 of this embodiment is set as a plate-like structure with a certain deformation amount, and the middle of the plate-like structure is bent to form the first section 21 and the second section 22. The first section 21 is limited and matched with the server chassis 30, and the second section 22 provides a hand-held position for the operator to remove the fan assembly 10 from the inside of the server chassis 30, thereby improving convenience. The operator applies force to the second section 22 to make the second section 22 close to the fan assembly 10, thereby driving the first section 21 away from the chassis limiting hole 1111, thereby releasing the limiting cooperation between the first section 21 and the chassis limiting hole 1111, and then allowing the fan assembly 10 to be separated from the server chassis 30.

[0048] In this embodiment, the side of the fan assembly 10 has an installation area, the operating part 20 is connected to the inner wall of the installation area, and a gap is formed between the two opposite sides of the operating part 20 and the installation area for the first limiting structure 211 to deform, so as to facilitate the deformation of the operating part 20 to quickly disassemble and assemble the fan assembly 10. Specifically, the first section 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 section 22. The gap is located on both sides of the first section 21 and extends in the first direction, so as to separate the first section 21 and the side wall of the fan assembly 10 in the first direction, so as to facilitate the deformation of the operating part 20. The first limiting structure 211 and the second section 22 are located on the same side of the fan assembly 10, so that when the operator applies force to the second section 22, the first section 21 can be more easily deformed, while avoiding deformation of the side wall of the fan assembly 10 to ensure the safety of the fan assembly 10.

[0049] Preferably, operating parts 20 are provided at both ends of the fan assembly 10 to achieve reliable connection of the fan assembly 10 .

[0050] In this embodiment, the fan assembly 10 includes a fan rack 11 and a fan 12. The fan rack 11 has a plurality of accommodating chambers, and the side wall of the accommodating chamber is provided with a second limiting portion 111; the fan 12 is detachably arranged in the accommodating chamber, and the side wall of the fan 12 is provided with a second limiting structure 125, and the second limiting structure 125 is engaged with the second limiting portion 111, and fixes the fan 12 in the accommodating chamber, thereby realizing reliable connection and convenient disassembly and assembly of the fan 12 and the fan assembly 10. Specifically, the fan rack 11 of this embodiment is provided with two accommodating chambers, and the accommodating chambers are arranged in a direction perpendicular to the first direction, and each accommodating chamber can accommodate a fan 12. A first limiting structure 211 is provided on the side of the side wall of the fan rack 11 away from the accommodating chamber, which can be limited and matched with the server chassis 30, thereby realizing the fixation of the fan rack 11 and the server chassis 30. The limiting method of the fan 12 in the accommodating cavity is similar to the limiting method of the fan rack 11 and the server chassis 30. When the fan 12 is set in the accommodating cavity, the second limiting structure 125 is engaged with the second limiting portion 111 to ensure the reliable fixation of the fan 12 and the fan rack 11; when the fan 12 is removed from the fan rack 11, the second limiting structure 125 is away from the second limiting portion 111 to achieve the unlocking of the fan 12 and the fan rack 11. Of course, according to actual needs, the fan rack 11 can also be provided with three or more accommodating cavities to accommodate more fans 12 to meet the heat dissipation requirements of the server; when the full number of fans 12 are not needed, the fan rack 11 can also be replaced without replacing it, and a model can be used to replace the fan 12 and placed in the accommodating cavity.

[0051] In this embodiment, the second limiting structure 125 is deformable relative to the fan frame 11, and the fan 12 has an unlocking portion 126, which is located at the entrance side of the accommodating chamber. The unlocking portion 126 is connected to the second limiting structure 125 and can drive the second limiting structure 125 to disengage from the second limiting portion 111, thereby realizing the unlocking of the fan 12 and the fan frame 11, so as to facilitate the removal of the fan 12 from the accommodating chamber. Specifically, the unlocking portion 126 of this embodiment is set to a semi-ring shape, the size of which is adapted to the shape of the operator's finger to improve the human-machine adaptability, and the unlocking portion 126 and the second limiting structure 125 are arranged in sequence along the first direction. The unlocking portion 126 and the second limiting structure 125 are located on different sides of the side wall of the accommodating chamber, and the second limiting structure 125 is arranged on the surface of the side wall of the accommodating chamber away from the accommodating chamber to facilitate the cooperation with the second limiting portion 111 outside the accommodating chamber; the unlocking portion 126 extends in a direction close to the center of the entrance side of the accommodating chamber, so as to avoid interference with other components. The side of the second limiting structure 125 facing the second limiting portion 111 is called the limiting side. The second limiting structure 125 has a first side and a second side arranged adjacent to the limiting side. The first side and the second side are arranged opposite to each other, and there is a deformation gap between the first side and the second side and the side wall of the accommodating chamber, so that the second limiting structure 125 is more easily deformed, so that the operator can easily and conveniently take the fan 12 out of the accommodating chamber. In this way, when the fan 12 needs to be taken out of the accommodating chamber, the operator pulls the unlocking portion 126 to move in the direction close to the center of the entrance side of the accommodating chamber, so that the unlocking portion 126 and the second limiting structure 125 are deformed by tension, and the unlocking portion 126 drives the second limiting structure 125 to move in the same direction, so that the second limiting structure 125 is away from the second limiting portion 111, thereby releasing the clamping fit between the second limiting structure 125 and the second limiting portion 111, and then the fan 12 can be taken out of the accommodating chamber, thereby improving the convenience of removing the fan 12, realizing the tool-free removal of the fan 12, and improving the removal efficiency of the fan 12.

[0052] In this embodiment, the second limiting portion 111 includes a limiting hole 1111 and a limiting protrusion 1112. When the fan 12 is located in the accommodating chamber, the second limiting structure 125 can be engaged in the limiting hole 1111. Along the direction in which the fan 12 enters the accommodating chamber, the limiting protrusion 1112 and the limiting hole 1111 are sequentially arranged on the side wall of the accommodating chamber, and the side of the limiting protrusion 1112 away from the limiting hole 1111 has an inclined guide surface, so that the second limiting portion 111 and the second limiting structure 125 are engaged and limited while providing guidance for the installation of the fan 12. Specifically, 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 accommodating chamber and approaches the side wall of the fan 12 along the first direction, thereby forming a guide surface inclined to the side wall of the accommodating chamber. The limiting hole 1111 can be set as a rectangular hole, and is set corresponding to the size of the second limiting structure 125, so that the second limiting structure 125 can smoothly extend into the limiting hole 1111 and can be reliably limited. The second limiting structure 125 can be set to the same structure as the first limiting structure 211, and also includes an inclined surface and a snap-on 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 frame 11, and is limited with the chassis limiting part 31. The second limiting structure 125 is set on the side wall of the fan 12, and is limited with the second limiting part 111, which will not be repeated. In this way, when the fan 12 is located in the accommodating chamber, the limiting hole 1111 is engaged with the second limiting structure 125 to prevent the second limiting structure 125 from falling out, and the limiting protrusion 1112 is provided with a plane at one end close to the limiting hole 1111 to further limit the second limiting structure 125, thereby ensuring that the fan 12 is reliably arranged in the accommodating chamber; during the installation of the fan 12 into the accommodating chamber, the second limiting structure 125 enters the accommodating chamber through the guidance of the inclined surface, and when it extends into the limiting protrusion 1112, The limiting protrusion 1112 squeezes the second limiting structure 125 to provide guidance for the continued installation of the fan 12 on the one hand, and squeezes the second limiting structure 125 to deform it on the other hand. When the second limiting mechanism extends into the limiting hole 1111, the second limiting structure 125 can quickly restore the deformation, so that the second lower limiting structure can extend into the limiting hole 1111, thereby cooperating with the limiting hole 1111 to lock the fan 12 in the accommodating cavity, thereby achieving rapid installation of the fan 12.

[0053] In the present embodiment, the fan assembly 10 further includes a fan baffle 13, which is arranged inside the fan frame 11 and divides the inside of the fan frame 11 into a plurality of accommodating chambers. The side wall of the fan frame 11 and the fan baffle 13 are both provided with a second limiting portion 111, so that a plurality of fans 12 can be installed in the fan assembly 10, and all fans 12 can be reliably connected. Specifically, the fan baffle 13 is arranged in a rectangular plate shape and is arranged parallel to the side wall of the fan frame 11 connected with the operating portion 20. The two ends of the fan assembly 10 connected to the operating portion 20 are respectively referred to as the first end and the second end arranged oppositely, and the second limiting portion 111 is arranged on the side wall of each accommodating chamber close to the first end, so that one second limiting portion 111 is arranged on the fan frame 11, and the other second limiting portions 111 are arranged on the fan baffle 13. Taking the two accommodating chambers of this embodiment as an example, one second limiting portion 111 is arranged on the side wall of the fan frame 11, and one second limiting portion 111 is arranged on the fan partition 13; if there are three accommodating chambers, one second limiting portion 111 is arranged on the side wall of the fan frame 11, and two second limiting portions 111 are arranged on the fan partition 13, and so on. Of course, according to the convenience of disassembling and assembling the fan 12, the second limiting portion 111 can also be arranged on the side wall of each accommodating chamber close to the second end.

[0054] Optionally, when the fan 12 has a more stringent connection reliability requirement, the second limiting portion 111 may be provided on both the side wall near the first end and the side wall near the second end of the accommodating chamber. However, in order to avoid interference, the position of the second limiting portion 111 needs 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 to disengage from the second limiting portion 111 as mentioned above, the unlocking portion 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 portion 111 is provided on both side walls of the accommodating chamber, the unlocking portion 126 can be provided on both opposite sides of the fan 12. The two unlocking portions 126 are symmetrically provided and extend toward the center of the fan 12 to avoid interference with other components.

[0055] In this embodiment, one of the fan baffle 13 and the fan 12 has a slide groove 112, and the other of the fan baffle 13 and the fan 12 has a slide bar 127. The slide groove 112 extends in the direction in which the fan 12 enters the accommodating cavity. The slide bar 127 is located in the slide groove 112 and can move along the slide groove 112, thereby achieving guidance during the disassembly and assembly process of the fan 12. Specifically, Figure 5 , Figure 6As shown, the fan baffle 13 of this embodiment is provided with a slide groove 112, and the two side walls of the fan baffle 13 facing the accommodating chamber are provided with slide grooves 112 to respectively cooperate with two adjacent fans 12. A slide bar 127 is provided on the side wall of the fan 12 close to the fan baffle 13, and the slide groove 112 and the slide bar 127 both extend along the first direction, so that when the fan 12 is installed in the accommodating chamber or the fan 12 is removed from the accommodating chamber, the slide bar 127 slides in the slide groove 112, and the slide groove 112 and the slide bar 127 provide guide limits for the fan 12, ensuring the smoothness of the installation and removal process of the fan 12, and can avoid the movement of the fan 12 when it is located in the accommodating chamber, so as to ensure the safety of the fan 12 in the accommodating chamber. Preferably, a plurality of slide grooves 112 and slide bars 127 are provided to further improve the stability of the fan 12 disassembly process. Optionally, the slide bar 127 and the slide groove 112 may not only be arranged on the fan baffle 13, but part of the slide groove 112 may also be arranged on the side wall of the fan frame 11 facing the accommodating chamber, and the slide bar 127 may be arranged on the side of the fan 12 close to the side wall of the fan frame 11, which can also play a guiding role. Of course, the slide bar 127 may also be arranged on the fan baffle 13, and the slide groove 112 may be arranged on the side wall of the fan 12 close to the accommodating chamber, which can also achieve the purpose of guidance.

[0056] 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 inlet air, and 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 discharge air, and 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 setting, on the one hand, can expose more surface area of ​​the fan 12 outside the fan frame 11, which is conducive to integrating the structural functions of the fan 12 and facilitating the setting of other components on the side of the fan 12. On the other hand, it is conducive to reducing the complexity of the fan frame 11 mold and saving costs. Specifically, Figure 5 As shown, the fan rack 11 of this embodiment is provided with two air inlets 113 and two air outlets 116, that is, one air inlet 113 and one air outlet 116 are provided for each accommodating cavity, and each air inlet 113 occupies no less than 70% of the area of ​​the side wall of the accommodating cavity, and each air outlet 116 occupies no less than 95% of the area of ​​the side wall of the accommodating cavity. The air inlet 113 is provided as a circular hole, and a limiting plate is provided only at two adjacent edges of the accommodating cavity on the air outlet side to limit the position of the fan 12, and the other positions on the air outlet side are all air outlets 116, so as to facilitate 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 accommodating cavities, the air inlet side and the air outlet side of the fan rack 11 can also be provided with more air inlets 113 and air outlets 116 to meet different heat dissipation requirements. Optionally, the fan rack 11 can be provided as a simple plastic part.

[0057] like Figure 3 As shown, in this embodiment, the bottom of the fan rack 11 has a positioning hole 114, and the positioning post of the server chassis 30 passes through the positioning hole 114 to position the fan assembly 10. The positioning hole 114 is set to be circular, and when the fan rack 11 is installed into the server chassis 30 along the first direction, the positioning post enters the positioning hole 114 to achieve the correct installation of the fan rack 11, which plays a fool-proof role.

[0058] In this embodiment, the bottom of the fan rack 11 has an observation hole 115 for observing information of the fan 12. The observation hole 115 is set in a square shape and is set 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 removing the fan 12, which is convenient for operation and maintenance and testing. According to actual needs, the size, shape and position of the observation hole 115 can be adjusted as long as the fan model can be identified.

[0059] In the present embodiment, the fan 12 includes a fan unit 121, a fan frame 122 and a grid 123. The fan frame 122 is located in the accommodating cavity and includes a plurality of sub-frames 1221. The sub-frames 1221 are engaged with each other through a hook structure to form an installation 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 a grid mounting hole. The grid 123 is rotatably connected to the fan frame 122 through the grid mounting hole. The fan 12 has an air suction side, and the grid 123 is located at the air suction side. Specifically, the fan frame 122 of the present embodiment includes two sub-frames 1221, namely a first sub-frame and a second sub-frame. The two sub-frames 1221 are both in the shape of a cuboid and are connected to each other to form the fan frame 122, thereby wrapping the fan unit 121 in the installation cavity. The first sub-frame is relatively small in size, and an upper cover is provided at the entrance side of the installation cavity to prevent the fan 12 from falling out of the installation cavity. The second sub-frame is relatively large in size, and the second limiting structure 125 and the slide bar 127 are both provided on the second sub-frame. The second sub-frame is not provided with an upper cover to facilitate the setting and deformation of the unlocking portion 126, thereby simplifying the structure, saving material costs, and reducing the complexity of the mold. The edges of the two sub-frames 1221 that are close to each other are respectively provided with hooks and holes, and the hooks extend into the holes to achieve the connection between the two sub-frames 1221, and at the same time, the sub-frames 1221 are fixed without tools, making the disassembly and assembly between the sub-frames 1221 more convenient. The air suction side of the fan 12, that is, the side where the fan 12 enters the air, is located on the same side as the air intake side of the fan rack 11.

[0060] The fan monomer 121 of this embodiment is set as a cylindrical structure, and the two surfaces of each sub-frame 1221 are arranged along the axial direction of the fan monomer 121. Fasteners are respectively provided at the four corners of the two surfaces to achieve reliable connection with the fan monomer 121. The fasteners and the sub-frame 1221 can be fixed in a fixed convex point manner, that is, fixed convex points are provided on the surface of the sub-frame 1221, and the fasteners are fixed on the fixed convex points. Optionally, the fasteners can be glue nails, which not only realizes the connection between the fan monomer 121 and the fan frame 122, but also the compressible properties of the glue nails themselves can absorb part of the vibration generated by the fan monomer 121 during operation, thereby reducing the vibration problem of the fan 12.

[0061] For the convenience of introduction, the sub-frame 1221 close to the air suction side is called the first sub-frame, and the sub-frame 1221 away from the air suction side is called the second sub-frame. The grid 123 of the present embodiment is arranged in the first sub-frame and connected to one end of the first sub-frame close to the air suction side. The grid 123 is arranged as a plate-like structure, connecting two opposite surfaces of the first sub-frame, and covering the air suction side of the fan 12, preventing the occurrence of local air backflow from affecting heat dissipation, and at the same time preventing impurities such as dust from being sucked into the fan 12 to cause malfunctions. The grid 123 includes a long grid 123 and a short grid 123, and the long grid 123 and the short grid 123 only differ in length, the long grid 123 is arranged at a position close to the center of the air suction side, and the short grid 123 is arranged at a position close to the edge of the air suction side. The length of the short grid 123 is shorter to avoid the connection structure of the sub-frame 1221 and the fan 12. The edge of the first subframe is provided with a long grid mounting hole and a short grid mounting hole, and a limiting structure of the grid 123 is provided, so as to ensure that the inclination direction of the grid 123 is consistent, thereby ensuring the consistency of the wind direction.

[0062] like Figure 7 As shown, in this embodiment, the fan frame 122 has a fan mesh structure 1223, and the fan mesh structure 1223 is located on the suction side and the blowing side of the fan 12, so as to prevent fingers from being accidentally inserted, ensure personnel safety, and make the structure beautiful. Optionally, 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 oppositely, and the suction side of the fan 12 is located on the same side as the air inlet side of the fan frame 11.

[0063] like Fig. 9As shown, in this embodiment, there is a foolproof structure 1222 between the sub-frames 1221. When the sub-frames 1221 are butted, the foolproof structures 1222 of the sub-frames 1221 are butted and matched, thereby ensuring that the hooks and the holes between the two sub-frames 1221 are smoothly buckled, thereby improving the assembly efficiency of the sub-frames 1221. The foolproof structure 1222 of this embodiment includes a protrusion and a groove. The protrusion is set on the first sub-frame, and the groove is set at the corresponding position of the second sub-frame. When assembling the sub-frames 1221, the protrusion is ensured to be located in the groove, which can ensure the smooth buckling of the hook and the hole, thereby avoiding assembly errors. Of course, the positions of the protrusion and the groove can be swapped without affecting the use effect.

[0064] In this embodiment, the fan module also has an identification member, which is located on the outer surface of the operating part 20 away from the accommodating cavity to indicate the position of the operating part 20, so as to facilitate the operator to accurately identify the operating part 20, thereby quickly realizing the disassembly and assembly of the fan assembly 10. The identification member can be in the form of blue silk screen printing, or in other ways, so as to facilitate the identification of the operator. Optionally, the unlocking part 126 can also be provided with an identification member to facilitate the operator to quickly identify the unlocking part 126, thereby improving the disassembly and assembly efficiency of the fan 12 and the fan frame 11; using the upper surface space of the upper cover of the first sub-frame, a wind flow mark can be set on the upper cover of the first sub-frame.

[0065] In this embodiment, the fan frame 122 has a limiter 1224. When the fan frame 122 is installed into the accommodating cavity, the limiter 1224 abuts against the fan frame 11 to control the installation position of the fan frame 122, thereby preventing the fan 12 from entering the accommodating cavity too deeply and causing damage to the fan terminal 124 on the surface of the fan 12 or other components such as the board-end connector. Specifically, the limiter 1224 of this embodiment is arranged on the first sub-frame and on the upper cover of the first sub-frame, that is, while the upper cover prevents the fan monomer 121 from escaping from the installation cavity, the edge of the upper cover extends horizontally a certain distance away from the installation cavity, so that when the fan 12 is installed into the accommodating cavity along the first direction and installed in place, the upper cover abuts against the upper surface of the side wall of the fan frame 11, thereby forming a limiter to prevent the fan 12 from continuing to move along the first direction.

[0066] like Figure 8 As shown, in this embodiment, the fan frame 122 has a wire hole 1228, which connects the installation cavity and the accommodating cavity to allow the cable to pass through. The wire hole 1228 is arranged on one side of the second sub-frame body close to the bottom of the fan frame 11, and is arranged on the same side wall as the fan net structure 1223. The wire hole 1228 is located at the edge of the second sub-frame body, thereby forming a natural gap to facilitate the entry and exit of the cable.

[0067] like Figure 6As shown, in this embodiment, the fan frame 122 has a wire management rack 1227 to fix the cables. The wire management rack 1227 is arranged on the side of the second sub-frame away from the first sub-frame. The wire management rack 1227 has a square hole for the cables to pass through, and there is an opening on the side of the square hole to facilitate the entry of the cables. In order to prevent the cables from falling out, the opening is preferably arranged upward. In this way, the wire management rack 1227 plans the wiring route for the fan 12, realizes the wiring of the cables of the fan terminal 124 from the fan monomer 121 to the wire hole 1228, and then to the terminal fixing structure 1225, and the semi-enclosed structure realizes the effect that the cables are easy to insert and difficult to withdraw. The wire management rack 1227 also has reinforcing ribs to improve the stability of the connection with the second sub-frame.

[0068] In this embodiment, the fan 12 further includes a fan terminal 124, the fan terminal 124 has a terminal protrusion 1241, the fan frame 122 has a terminal fixing structure 1225, the terminal fixing structure 1225 has a terminal mounting hole, and when the fan terminal 124 is located in the terminal mounting hole, the terminal protrusion 1241 is limitedly matched with the terminal mounting hole. Specifically, Figure 7 As shown, the terminal fixing structure 1225 and the wire management frame 1227 are arranged on the same side of the fan frame 122, and the wire management frame 1227 and the terminal fixing structure 1225 are arranged along the first direction. A terminal fixing hole is arranged in the middle of the terminal fixing structure 1225, and the terminal fixing hole has a large cross-section section and a small cross-section section, and is arranged in sequence along the first direction. A plurality of recesses are arranged around the small cross-section section. Fig.10 As shown, the fan terminal 124 has a large end and a small end, and a plurality of terminal protrusions 1241 are provided on the side of the small end. In this way, when installing the fan terminal 124, it is installed along the first direction; when the fan terminal 124 is located in the terminal installation hole, the large end is located in the large cross-section section, the small end is located in the small cross-section section, and the terminal protrusion 1241 is located in the recess, thereby forming a limit for the fan terminal 124 to fix the position of the fan terminal 124 and prevent the fan terminal 124 from moving laterally. Optionally, a fan terminal 124 with a smaller plugging and unplugging force can be customized to make the plugging and unplugging of the fan terminal 124 simpler, thereby facilitating the plugging and unplugging of the operator.

[0069] like Figure 2 , Figure 4As shown, in this embodiment, the terminal fixing structure 1225 further has an elastic member 1226, and the elastic member 1226 is connected to the fan frame 122. When the fan terminal 124 is inserted into the terminal mounting hole, the elastic member 1226 abuts against the fan terminal 124 and prevents the fan terminal 124 from slipping out of the terminal mounting hole. The elastic member 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 member 1226 is inclined relative to the side wall of the fan frame 122. The upper end of the elastic member 1226 is connected to the fan frame 122, and the lower end is away from the fan frame 122 and close to and located 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, and the elastic member 1226 is squeezed to the fan frame 122. When the fan terminal 124 is installed in the terminal mounting hole, the lower end of the elastic member 1226 returns to the upper part of the terminal mounting hole, thereby limiting the fan terminal 124, achieving the fixation of the fan terminal 124, and preventing the fan terminal 124 from falling out from the upper part of the terminal mounting hole. When the fan terminal 124 is taken out from the terminal mounting hole, it is only necessary to move the elastic member 1226 to move the lower end of the elastic member 1226 in the direction close to the fan frame 122, and then move the fan terminal 124 in the opposite direction of the first direction, so as to achieve the removal of the fan terminal 124. In this way, the terminal fixing structure 1225 achieves the fixation of the fan terminal 124, is easy to install, and does not require additional locking parts to fix the fan terminal 124, which is conducive to cost saving. Optionally, the elastic member 1226 may adopt a spring-type structure.

[0070] In this embodiment, the fan assembly 10 further includes a wind shield, which is disposed in the gap between the fan rack 11 and the server chassis 30 and blocks the gap to prevent air backflow. Optionally, the wind shield can be a wind shield foam, which is disposed on the periphery of the fan rack 11 to block the gap between the fan rack 11 and the server chassis 30.

[0071] In this embodiment, the fan assembly 10 further includes a honeycomb member 1229, which includes a plurality of honeycomb mesh-shaped small holes. The honeycomb member 1229 is connected to the fan frame 122 and is covered on the air suction side of the fan frame 122, that is, the honeycomb member 1229 covers the entire air inlet hole 113 of the fan frame 11, so that when the speed of the fan monomer 121 is high, the noise can be better absorbed, thereby reducing the noise of the fan assembly 10.

[0072] The fan assembly 10 of this embodiment also includes a light guide column for indicating the state of the fan 12. The light guide column is arranged on the fan frame 122 and is electrically connected to the fan unit 121. Thus, the light guide column transmits light to detect the operating state of the fan 12 in real time and display the faulty fan 12 for easy identification. Optionally, a display light may also be arranged on the fan board of the server. The light guide column is electrically connected to the fan board, so that the faulty fan 12 can be further quickly identified by the color change of the display light.

[0073] In the present embodiment, the fan 12 further includes an extension piece, which is detachably connected to the end of the fan monomer 121 and can be docked with the fan frame 122, so that the fan frame 122 can adapt to fans 12 of different specifications, thereby improving the adaptability of the fan assembly 10. The fan monomer 121 is generally set as a cylindrical structure, so the extension piece is also set as a cylindrical structure with the same diameter as the fan monomer 121. When the axial length of the fan monomer 121 is small and cannot be adapted to the fan frame 122, the fan monomer 121 is connected and fixed with the extension piece, and then the assembly of the fan monomer 121 and the extension piece is placed in the installation cavity to realize the coordinated use of the fan frame 122 with fan monomers 121 of different specifications, so that fans 12 of multiple specifications can share the same specification of the fan frame 122, so that the fan frame 122 can adapt to more usage scenarios and is easy to replace.

[0074] The present application also provides a server, including a server chassis 30 and the above-mentioned fan module for the server, the fan module is located in the server chassis 30, the server chassis 30 includes a chassis limiter 31, when the fan module is connected to the server chassis 30, the first limiter structure 211 of the fan module is engaged with the chassis limiter 31, and prevents the fan module from being separated from the server chassis 30, thereby ensuring the stability of the fan module during the operation of the server, avoiding the decrease in heat dissipation efficiency due to the looseness of the fan module, thereby improving the stability and reliability of the server. Fig.11 , Fig.13 As shown, the server chassis 30 of this embodiment is provided with a chassis limiting plate, which is located on one side of the server chassis 30, parallel to and spaced from a side wall of the server chassis 30, and a chassis limiting portion 31 is provided on the chassis limiting plate, and the chassis limiting portion 31 can be provided as a rectangular chassis limiting hole 1111.

[0075] In this embodiment, the server further includes a mainboard, and a first wiring gap for wiring is provided between the fan frame 11 of the fan module and the mainboard, thereby facilitating wiring inside the server chassis 30. That is, along the first direction, the fan module and the mainboard of this embodiment are arranged in sequence, and the cables of the mainboard or the fan 12 or other devices can pass between the mainboard and the fan module to facilitate wiring between the devices.

[0076] In this embodiment, a second wiring gap 32 for wiring is provided between the side wall of the server chassis 30 and the fan module, thereby providing wiring space for cables inside the server. The first limiting structure 211 of the fan module of this embodiment is limitedly matched with the chassis limiting portion 31, so 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, and this part of the space is the second wiring gap 32.

[0077] In this embodiment, the server chassis 30 further includes a fixing member 40, and there are multiple fan modules. The fixing member 40 is located between two adjacent fan modules and cooperates with the first limiting structure 211 of the fan module to achieve a reliable connection between the fan module and the server chassis 30.

In this way, one end of the fan module is connected to the chassis limiting plate close to the side wall of the server chassis 30, and the other end of the fan module is connected to a side panel of the fixing member 40, so that the fan module is firmly fixed in the server chassis 30. Of course, the number of fan modules can be adjusted according to factors such as heat dissipation requirements and the space in the server chassis 30. Only one set of fan modules can be set, and the two ends of the fan modules are respectively connected to the chassis limit plates close to the side walls of the server chassis 30; more fan modules can also be set, and the fan modules with fan modules at both ends are connected to the fixing member 40 or other structures on the server chassis 30 with chassis limit plates. The fan modules close to the side walls of the server chassis 30 are connected in a similar manner to when two sets of fan modules are set, and will not be repeated. Optionally, 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.

[0078] In this embodiment, the server further includes a cover body that is covered on the server chassis 30, and the fixing member 40 has a wiring channel 42 for wiring, so as to facilitate the wiring in the server chassis 30. The space between the three side panels and the top panel of the fixing member 40 of this embodiment is the wiring channel 42, and the three side panels have flanges on the side away from the top panel to facilitate connection with the bottom of the server chassis 30. Through holes can be provided between the flanges and the side panels to facilitate wiring, and the through holes can be used as an inlet or outlet for cables, so that the cables can enter and exit the wiring channel 42, thereby making full use of the space between the two fan modules, having a compact structure, and being conducive to optimizing the internal layout of the server chassis 30.

[0079] like Fig.12 , Fig.13 As shown, the fixing member 40 of this embodiment has a locking structure 41, and the fixing member 40 is locked with the cover body through the locking structure 41, thereby improving the safety and reliability of the server.
