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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] like Figures 1 to 17 A fan module for a server is shown, comprising a fan assembly 10 and an operating member 20. The fan assembly 10 is detachably arranged in a server chassis 40. The fan assembly 10 has a docking portion 11, and the docking portion 11 can be positioned and docked with a locking portion 411 of the server chassis 40; the operating member 20 is movably arranged at the docking portion 11, and the operating member 20 has a locking position and a releasing position. When the operating member 20 is in the locking position, the operating member 20 and the locking portion 411 are limited and prevent the docking portion 11 from being separated from the locking portion 411. When the operating member 20 is in the releasing position, the operating member 20 and the locking portion 411 are avoided and cooperated, and the docking portion 11 and the locking portion 411 can be separated to disassemble the fan assembly 10.

[0047] In this embodiment, the operating member 20 and the docking portion 11 are provided so that the fan module can be conveniently and quickly plugged in and out, thereby improving the installation and removal efficiency of the fan module and realizing tool-free installation. Specifically, the staff operates the operating member 20 to switch between the locking position and the releasing position, and cooperates with the limiting cooperation of the docking portion 11 and the locking portion 411, thereby driving the fan module to move relative to the server chassis 40, so that when the operating member 20 is in the locking position, the fan module is locked inside the server chassis 40 and can work normally. When maintenance is required, the operating member 20 is operated to the releasing position, so that the fan module can be completely separated from the server chassis 40, thereby realizing the overall installation and overall disassembly of the fan module, which is beneficial to improving work efficiency and reducing the labor intensity of the staff.

[0048] It should be noted that the direction in which the fan assembly 10 of this embodiment is connected to the server chassis 40 is the direction in which the fan assembly 10 enters the server chassis 40. Figure 1 The direction in which the fan assembly 10 moves from top to bottom; the direction in which the fan assembly 10 is disconnected from the server chassis 40, that is, the direction in which the fan assembly 10 moves away from the server chassis 40, refers to Figure 1 This embodiment only takes the example of the fan assembly 10 connecting and disconnecting with the server chassis 40 in the up and down direction as an example. According to actual needs, the fan assembly 10 can also enter and leave the server chassis 40 horizontally from the side of the server chassis 40, and the structure of this embodiment is also applicable to it.

[0049] In this embodiment, the operating member 20 is rotatably connected to the fan assembly 10, and the operating member 20 has a limiting channel 21 with a circumferential side opening. When the operating member 20 is in the locked position, the locking portion 411 is located in the limiting channel 21 and cooperates with the side limiting of the limiting channel 21. When the operating member 20 is in the released position, the locking portion 411 is located outside the limiting channel 21, so that the plugging and unplugging of the fan module is achieved through the cooperation of the locking portion 411 and the limiting channel 21. Specifically, the operating member 20 of this embodiment has a handle portion and a rotating portion. The handle portion is mainly for the convenience of the operator to rotate the operating member 20. The rotating portion is rotatably connected to the fan assembly 10 and is provided with a limiting channel 21. The handle portion is located on one side of the circumferential direction of the rotating portion and extends in a direction away from the rotating portion. The first end of the limiting channel 21 is located at the circumferential side of the rotating portion and is open. The second end of the limiting channel 21 extends to the inner side of the rotating portion. The direction in which the handle portion extends away from the rotating portion is opposite to the direction in which the second end of the limiting channel 21 extends to the first end.

[0050] When the operating handle rotates the operating member 20, the locking member 411 is fixed, and the handle drives the limiting channel 21 to rotate, so that the locking member 411 abuts against the side of the limiting channel 21, thereby driving the operating member 20 to move relative to the server chassis 40, thereby realizing the plugging and unplugging of the fan module. Specifically, when the operating member 20 switches from the locking position to the releasing position, as the operating member 20 rotates, the locking member switches from the second end of the limiting channel 21 to the first end of the limiting channel 21, thereby driving the fan assembly 10 to separate from the server chassis 40; when the operating member 20 switches from the releasing position to the locking position, the locking member switches from the first end of the limiting channel 21 to the second end of the limiting channel 21, thereby driving the fan assembly 10 to connect with the server chassis 40. In this way, the locking and releasing of the fan assembly 10 is realized by rotating the operating member 20, which is not only simple to operate, but also can effectively prevent equipment damage caused by improper operation, thereby improving maintenance efficiency.

[0051] Preferably, an anti-slip boss is provided in the middle part of the limiting channel 21, that is, an anti-slip boss is provided between the first end and the second end of the limiting channel 21, and the anti-slip boss is provided on the side of the limiting channel 21 away from the center of the rotating part, so that when the locking part 411 is located at the second end of the limiting channel 21, the anti-slip boss can provide a limit for the locking part 411, thereby preventing the locking part 411 from easily moving from the second end to the first end, causing the fan assembly 10 to easily detach from the server chassis 40 and causing server failure, thereby improving the safety and reliability of the server.

[0052] Of course, the connection method between the operating member 20 and the fan assembly 10 is not limited to rotation, and other connection methods can also be used. For example, the operating member 20 can be set to be slidably connected to the fan assembly 10, and a slider is set on the operating member 20, and a slide rail is set on one side of the fan assembly 10. The extension direction of the slide rail is neither parallel to the horizontal direction nor to the vertical direction, but forms an angle with the horizontal direction. The slider is located in the slide rail and can move relative to it. The locking portion 411 is fixed and cooperates with the slider to fix the slider at the same horizontal height. When the operating member 20 is driven to move, when the slider has a horizontal displacement relative to the slide rail, the fan assembly 10 can generate a height displacement with the server chassis 40, so that the fan assembly 10 moves relative to the server chassis 40, thereby realizing the connection and disconnection of the fan assembly 10 with the server chassis 40.

[0053] In this embodiment, the fan assembly 10 includes an outer frame 12 and a docking portion 11. The docking portion 11 is arranged on the outer side of the outer frame 12. The docking portion 11 has a receiving cavity. At least a part of the operating member 20 is located in the receiving cavity. The side of the receiving cavity has an avoidance notch 112 for avoiding the locking portion 411. When the fan assembly 10 is installed in the server chassis 40, the locking portion 411 is located at the avoidance notch 112, so that the docking portion 11 provides an installation position for the operating member 20 on the one hand, thereby protecting the operating member 20 and avoiding accidental touch. On the other hand, when the operating portion rotates, the locking portion 411 moves relative to the docking portion 11 at the avoidance notch 112, thereby realizing the movement of the fan assembly 10 relative to the server chassis 40. Specifically, as Figure 8 , Fig. 9 As shown, the outer frame 12 is set as a rectangular frame structure, and the docking portion 11 is set at the side plate in the width direction of the outer frame 12 to reduce space occupation. Figure 3 , Figure 5 As shown, the docking portion 11 is configured as a cover-like structure with multiple openings, the side panels of the docking portion 11 and the outer frame 12 in the width direction are arranged opposite to each other, the side panels in the width direction of the outer frame 12 block the opening of the accommodating cavity toward the outer frame 12, and the operating member 20 is located between the docking portion 11 and the outer frame 12. An avoidance notch 112 is provided on the side of the docking portion 11 away from the outer frame 12. The avoidance notch 112 is located at the edge of the docking portion 11 and forms an opening toward the inside of the server chassis 40 along the direction in which the fan assembly 10 is disconnected from the server chassis 40. In this way, when the operating member 20 is rotated to the release position, the avoidance notch 112 moves along the direction in which the fan assembly 10 is disconnected from the server chassis 40 and moves away from the locking portion 411, thereby realizing the disassembly of the fan assembly 10. When the operating member 20 is rotated to the locking position, the avoidance notch 112 moves along the direction in which the fan assembly 10 is connected to the server chassis 40 and moves close to the locking portion 411, so that the locking portion 411 is located on the side of the avoidance notch 112 close to the center of the docking portion 11, thereby realizing the installation of the fan assembly 10.

[0054] It should be noted that the length direction of the outer frame 12 refers to Figure 8 In the direction from the lower left to the upper right, the width direction of the outer frame 12 refers to Figure 8 In the direction from the upper left to the lower right, the height direction of the outer frame 12 refers to Figure 8 The vertical direction is the direction in which the fan assembly 10 and the server chassis 40 move relative to each other. The side panels in the width direction of the outer frame 12 refer to the side panels extending along the width direction and the height direction of the outer frame 12, that is, the side panels connected to the operating member 20, that is, Figure 8 The side plate on the left side is called the first side plate 127. Of course, the operating member 20 can also be arranged at the side plate extending along the length direction and the height direction of the outer frame 12. Considering the reduction of space occupation, the operating member 20 is arranged at the side plate in the width direction of the outer frame 12 in this embodiment.

[0055] The outer frame 12 of this embodiment adopts an integrated iron cage immersed design, and the side panel in the width direction of the outer frame 12, that is, the first side panel 127, has two opposite sides, so the operating member 20 and the docking portion 11 are also set to two, so that operation can be performed at both ends of the length direction of the fan assembly 10, thereby realizing the installation and disassembly of the fan assembly 10.

[0056] like Figure 2 As shown, in the present embodiment, a fastening structure is arranged between the docking portion 11 and the outer frame 12, and the docking portion 11 is connected to the outer frame 12 through the fastening structure, and the fastening structure includes a mounting hole 122 and a fastener 123, wherein the side of the outer frame 12 has an extending arm 126 extending at an angle, and the extending arm 126 and the surface of the docking portion 11 facing the extending arm 126 are provided with a mounting hole 122, and the fastener 123 is passed through the mounting hole 122 to connect the docking portion 11 and the outer frame 12, thereby improving the connection strength between the docking portion 11 and the outer frame 12, improving the reliability of the server, and avoiding the loosening of the connection between the docking portion 11 and the outer frame 12 due to vibration, etc., and when the docking portion 11 fails, it is only necessary to remove the fastener 123 to separate the docking portion 11 and the outer frame 12, thereby facilitating the separate maintenance of the docking portion 11 and avoiding the overall maintenance of the fan module, thereby reducing costs.

[0057] Specifically, the docking portion 11 of the present embodiment has two relative connecting surfaces that are both perpendicular to the first side plate 127 of the outer frame 12. The first side plate 127 is provided with two extending arms 126 along the length direction of the outer frame 12 toward the direction close to the docking portion 11. The two extending arms 126 extend into the accommodating cavity and respectively fit with the surfaces of the two connecting surfaces of the docking portion 11. Both the extending arms 126 and the connecting surfaces are provided with mounting holes 122. During installation, after the docking portion 11 is buckled onto one side of the operating member 20, the connecting surface and the extending arms 126 are fixed by the fasteners 123, thereby fixing the docking portion 11 and the outer frame 12.

[0058] Of course, the positions of the mounting holes 122 and the fasteners 123 are not unique, and they can also be set at other positions. For example, the first side plate 127 can be provided with no extension arm 126, and the fasteners 123 are directly inserted into the docking portion 11 and the first side plate 127, so as to achieve the locking of the docking portion 11 and the outer frame 12. Figure 6 As shown, in another alternative embodiment, the first side plate 127 and the surface of the docking part 11 facing the first side plate 127 are both provided with mounting holes 122, and the fasteners 123 are inserted into the mounting holes 122 to connect the docking part 11 and the outer frame 12, thereby achieving the fixation of the docking part 11 and the outer frame 12. Specifically, since the docking part 11 and the server chassis 40 are connected by sliding, a protrusion is provided on the surface of the docking part 11 facing the width direction of the outer frame 12, so that a slide groove is formed on the surface of the side of the docking part 11 away from the width direction of the outer frame 12, thereby achieving the sliding connection with the server chassis 40. In this way, the protrusion on the surface of the docking part 11 facing the first side plate 127 is used to fit with the surface of the first side plate 127, and both are provided with mounting holes 122, so that the fasteners 123 are inserted into the mounting holes 122 to fix the docking part 11 and the outer frame 12.

[0059] In this embodiment, the operating member 20 is rotatably connected to the fan assembly 10, and the fan module further includes a first connecting member 30, which includes a first section 31 and a second section 32 that are axially connected in sequence, the first section 31 having a threaded structure and connected to the fan assembly 10, and the operating member 20 is rotatably sleeved on the outer peripheral side of the second section 32, so that the operating member 20 is connected to the fan assembly 10, and the operating member 20 can rotate relative to the fan assembly 10. Specifically, as Figure 7 As shown, the first section 31 and the second section 32 of the first connecting member 30 of the present embodiment are both set to be cylindrical and coaxially arranged. The outer diameter of the second section 32 is larger than the outer diameter of the first section 31. Only the first section 31 is set with a threaded structure, and the second section 32 is set as a smooth rod. In this way, the first section 31 extends into the threaded hole of the first side plate 127 of the fan assembly 10 and is fixed thereto, and the second section 32 is passed through the smooth hole of the rotating part of the operating member 20, so that the operating member 20 is installed at the first side plate 127 through the first connecting member 30, and the rotation of the operating member 20 relative to the fan assembly 10 is realized. Compared with ordinary screws, the first connecting member 30 of the present embodiment adds a smooth rod of the second section 32, which can not only realize the installation of the operating member 20, but also realize the anti-slip rotation of the operating member 20. Preferably, the first connecting member 30 also has a third section, which is connected to the side of the second section 32 away from the first section 31 and is coaxially arranged. The third section is also arranged to be cylindrical, and the outer diameter is larger than the inner diameter of the light hole of the rotating part to prevent the rotating part from falling off from the first side plate 127.

[0060] The connection method between the operating member 20 and the fan assembly 10 is not unique, and other connection methods may also be used. In another embodiment not shown in the figure, the operating member 20 is rotatably connected to the fan assembly 10, and the fan module also includes a sleeve and a second connecting member, the second connecting member is inserted into the sleeve and is threadedly connected to the fan assembly 10, and the operating member 20 is rotatably sleeved on the outer peripheral side of the sleeve, thereby realizing the rotatable connection between the operating member 20 and the fan assembly 10. Specifically, a threaded structure is provided on the outer peripheral side of the second connecting member, so as to be threadedly connected to the threaded hole of the first side plate 127, and the sleeve is provided as a cylindrical structure with a hollow interior, and the outer peripheral surface is a smooth surface, so that the sleeve is sleeved on the outer peripheral surface of the second connecting member and is inserted into the light hole of the rotating part, so that the operating member 20 is fixed to the first side plate 127, and the operating member 20 can also be rotated along the surface of the first side plate 127.

[0061] In this embodiment, the operating member 20 has an elastic portion 22, and the fan assembly 10 has a positioning hole 124. When the operating member 20 is active, the elastic portion 22 can extend into or out of the positioning hole 124. There are one or more positioning holes 124. When there are more than one positioning holes 124, the elastic portion 22 cooperates with different positioning holes 124 when the operating member 20 is in the locked position and the released position, so that the operating member 20 can switch between the locked position and the released position more reliably, avoiding the problem of inaccurate positioning due to improper operation, which may cause the fan assembly 10 to fail to be plugged in or out. Specifically, Figure 4 As shown, an elastic portion 22 is provided at the rotating portion of the operating member 20, and the elastic portion 22 is configured to be in the shape of a spring, one end of the elastic portion 22 is connected to the rotating portion, and the other end is configured to be a positioning protrusion facing the first side plate 127. In this embodiment, two positioning holes 124 are provided, and the distance between the positioning hole 124 and the rotation center of the operating member 20 is equal to the distance between the positioning protrusion and the rotation center of the operating member 20, that is, the distance between the positioning hole 124 and the threaded hole of the first side plate 127 is equal to the distance between the positioning protrusion and the light hole of the operating member 20, so that the positioning protrusion can just enter the positioning hole 124 to achieve positioning after the operating member 20 is rotated into place, thereby realizing the switch stroke limitation of the operating member 20. When the operating member 20 is rotated to the locking position, the positioning protrusion enters one of the positioning holes 124 to remind the operator to rotate it into place, thereby preventing the operator from continuing to rotate it after rotating it to the locking position, thereby causing the fan assembly 10 to fail to be installed; when the operating member 20 is rotated to the release position, the positioning protrusion enters the other positioning hole 124 to remind the operator to rotate it into place, thereby preventing the operator from continuing to rotate it after rotating it to the release position, thereby causing the fan assembly 10 to fail to be disassembled.

[0062] In the present embodiment, the fan assembly 10 includes an outer frame 12, a partition 13 and a plurality of fans 14. The outer frame 12 has an installation space. The partition 13 is located in the installation space and divides the installation space into a plurality of sub-spaces. At least some of the sub-spaces are arranged in sequence along the extension direction of the outer frame 12. The fans 14 are arranged in the sub-spaces. On the one hand, the fan assembly 10 can accommodate a plurality of fans 14, so that different areas of the server can be accurately cooled. On the other hand, the arrangement of the partition 13 allows the plurality of fans 14 to be arranged in different sub-spaces, respectively, so that it is convenient to maintain a single fan 14. Specifically, the partitions 13 of the present embodiment are arranged in plurality. Due to the rectangular structure of the outer frame 12, the partitions 13 are arranged along the length direction of the outer frame 12, thereby forming sub-spaces arranged along the length direction of the outer frame 12, so that the fans 14 are arranged along the length direction of the outer frame 12. In this way, the fans 14 and the partitions 13 are arranged adjacent to each other, and the fans 14 are arranged in only one row, which is conducive to reducing the width dimension of the outer frame 12, thereby increasing the wiring space on both sides of the width direction of the outer frame 12. Fig.10 As shown, the partition 13 of this embodiment is set to be plate-shaped, and its width is consistent with the size of the subspace along the width direction of the outer frame 12, and its height is consistent with the size of the subspace along the height direction of the outer frame 12. When the partition 13 is installed, the partition 13 is arranged in parallel with the first side plate 127 of the outer frame 12, so as to form a rectangular subspace. Five partitions 13 are arranged in this embodiment, so as to form six subspaces. Therefore, the outer frame 12 of this embodiment can accommodate up to six fans 14, and the six fans 14 are distributed in an array. Of course, the number of partitions 13 and fans 14 is not limited. According to actual needs, only one partition 13 can be set to form two subspaces. In this way, two fans 14 are set in the installation space, or multiple partitions 13 can be set. According to actual heat dissipation needs, fans 14 are only set in some of the subspaces. For example, in the six subspaces of this embodiment, fans 14 can be set in only four of them. In addition, according to the structural form of the outer frame 12, the arrangement of the fans 14 is not fixed. For example, when the outer frame 12 is set to be ring-shaped, the partitions 13 are also arranged along a circular array, so that the fans 14 are also arranged along a circle.

[0063] In this embodiment, at least one of the partition 13 and the outer frame 12 has a rivet hole 125, and at least one of the partition 13 and the outer frame 12 has a rivet protrusion 131. The rivet protrusion 131 is located in the rivet hole 125 to position and fix the partition 13 and the outer frame 12, thereby simplifying the connection structure of the partition 13 and the outer frame 12, reducing the use of small parts such as screws and rivets, and ensuring the stability of the connection. Specifically, the edge of the partition 13 of this embodiment has a connecting plate extending along the length direction of the outer frame 12, and the connecting plate includes a bottom connecting plate and a top connecting plate, wherein the bottom connecting plate is arranged at the bottom edge of the partition 13, and extends horizontally so as to be parallel to the bottom plate of the outer frame 12, thereby realizing connection with the bottom plate of the outer frame 12, and the top connecting plate is arranged at the top of the side of the partition 13, and extends in another direction so as to be parallel to the side plate of the length direction of the outer frame 12, thereby realizing connection with the side plate of the length direction of the outer frame 12. In this embodiment, the bottom connecting plate of the partition 13 is provided with a rivet hole 125, and the bottom plate of the outer frame 12 is provided with a rivet protrusion 131, so as to achieve connection; the top connecting plate of the partition 13 is provided with a rivet protrusion 131, and the side plate extending along the length direction of the outer frame 12 is provided with a rivet hole 125, so as to achieve connection. In this way, through the cooperation of the rivet hole 125 and the rivet protrusion 131, on the one hand, the use of small parts such as screws and rivets is reduced, which is conducive to simplifying the structure of the fan assembly 10, and on the other hand, the stability of the connection between the partition 13 and the outer frame 12 is guaranteed, and the problem of small parts such as screws and rivets loosening and falling off caused by the vibration of the server is avoided. Moreover, the installation is relatively simple, and it is only necessary to align the rivet protrusion 131 with the rivet hole 125 for riveting, which is conducive to reducing the work intensity of the operator. Of course, the bottom connecting plate and the top connecting plate of the partition 13 can also be set to other structural forms, which can achieve reliable connection with the outer frame 12. For example, riveting protrusions 131 may be provided on both the bottom connecting plate and the top connecting plate, and riveting holes 125 may be provided at corresponding positions of the outer frame 12 , which can also achieve a stable connection between the partition plate 13 and the outer frame 12 .

[0064] Preferably, a positioning convex point can be provided on one side of the connection between the bottom plate of the outer frame 12 and the partition 13, which is helpful for the precise riveting between the partition 13 and the outer frame 12. In this way, when the partition 13 is installed, the partition 13 enters the installation space. Since the riveting protrusion 131 needs to be aligned with the riveting hole 125, the bottom connecting plate of the partition 13 will block the riveting protrusion 131 of the bottom plate of the outer frame 12. At this time, the operator can judge the position where the partition 13 should be placed by identifying the position of the positioning convex point, thereby realizing the rapid alignment of the riveting protrusion 131 and the riveting hole 125, thereby improving the installation efficiency of the partition 13.

[0065] In this embodiment, the partition 13 has a snap-in hole 132, and the fan 14 is provided with a snap-in portion 143. The snap-in portion 143 snaps with the snap-in hole 132, and the fan 14 is installed on the partition 13. In this way, the elasticity of the snap-in portion 143 enables quick installation and removal between the single fan 14 and the partition 13, thereby achieving tool-free maintenance of the single fan 14. Specifically, the snap-in hole 132 of this embodiment is provided at the top of the partition 13, and the snap-in portion 143 is provided at the top of the side of the fan 14 close to the partition 13. The snap-in portion 143 is provided as a strip-shaped protrusion, and the snap-in hole 132 is also provided as a strip-shaped hole. When the fan 14 is fixed in the subspace, the strip-shaped protrusion is embedded in the strip-shaped hole, so that the fan 14 cannot be separated from the subspace. Preferably, the side of the snap-in hole 132 close to the bottom of the outer frame 12 is set as an inclined surface, and the side away from the bottom of the outer frame 12 is set as a horizontal plane, so that when the fan 14 is installed in the sub-space, the inclined surface can play a guiding role in the process of the snap-in portion 143 entering the snap-in hole 132, so that the installation of the fan 14 can be smoother and more labor-saving. When the snap-in portion 143 completely enters the snap-in hole 132, the horizontal plane can play a limiting role to prevent the snap-in portion 143 of the fan 14 from escaping from the snap-in hole 132, thereby ensuring the reliable connection of the fan 14. A handle is provided above the clamping portion 143 of the fan 14. The handle is provided in the form of a rectangular frame structure to facilitate the operator to hold it. Only the bottom of the handle is connected to the clamping portion 143, and the top of the handle is inclined toward the center of the fan 14, so that when the operator applies a force away from the bottom of the outer frame 12 to the handle, the handle can pull the clamping portion 143 out of the clamping hole 132, thereby realizing the disassembly of the fan 14 and the partition 13, so that the fan 14 can be separated from the subspace. A top notch is provided above the clamping hole 132 and at the top edge of the partition 13. The extension length of the top notch along the width direction of the partition 13 is not less than the extension length of the clamping hole 132, so that on the one hand, the partition 13 is prevented from squeezing the handle to make the clamping portion 143 separate from the clamping hole 132, and on the other hand, an operating space is provided for the operator to pull the handle. In this way, the installation and disassembly of the fan 14 are more convenient, no additional tools are required, and work efficiency is improved.

[0066] The fan 14 of the present embodiment only needs to be fixed to the partition 13 on one side through the snap-in portion 143 and the snap-in hole 132. Along the length direction of the outer frame 12, when each fan 14 is provided with a snap-in portion 143 on its side close to the first side plate 127 and snap-fitted with the partition 13, then one of the fans 14 adjacent to the first side plate 127 needs to be snap-fitted with the first side plate 127.

[0067] Specifically, the outer frame 12 has a snap-in hole 132, and the fan 14 is provided with a snap-in portion 143. The snap-in portion 143 snaps in with the snap-in hole 132, and the fan 14 is installed on the outer frame 12. The outer frame 12 also has a flange structure 128 that folds into the installation space. Along the direction in which the fan 14 leaves the outer frame 12, the snap-in hole 132 and the flange structure 128 are arranged in sequence, thereby ensuring the stability of the fan 14 after installation. In other words, the first side panel 127 is also provided with a snap-in hole 132 that snaps in with the snap-in portion 143 of the fan 14. This part is consistent with the cooperation mode between the partition 13 and the fan 14. The installation and disassembly between the fan 14 and the outer frame 12 are achieved by the elasticity of the snap-in portion 143, which will not be repeated. Unlike the partition 13, the first side panel 127 is not provided with a top notch, such as Fig. 9 As shown, the first side plate 127 is provided with a flange structure 128 on the surface above the clamping hole 132 facing the fan 14, so as to further limit the clamping portion 143, and prevent the clamping portion 143 from being separated from the first side plate 127 and causing the fan 14 to be separated from the sub-space. In addition, the threaded hole on the first side plate 127 that cooperates with the operating member 20 has a protrusion protruding toward the sub-space, which can also play a role in limiting the clamping portion 143.

[0068] In this embodiment, the fan assembly 10 further includes a windshield, which is disposed at the bottom of the outer frame 12 and extends downward by a predetermined distance. The windshield extends along the length direction of the outer frame 12, thereby shielding the gap between the outer frame 12 and other components inside the server chassis 40, and preventing the wind blown out by the fan 14 from flowing back. Optionally, the windshield can be made of windshield foam and pasted on the bottom of the outer frame 12. The windshield of this embodiment is located on the same side as the blowing side of the fan 14, thereby improving the effectiveness of the blowing of the fan 14, and further improving the heat dissipation efficiency of the fan assembly 10.

[0069] The fan assembly 10 of this embodiment further includes a connecting frame 16, which is connected to the top of the outer frame 12 and has a fixing pin for connecting and fixing with the server cover. Fig.12As shown, the connecting frame 16 of this embodiment is set as a triangular bracket structure and is fixed in the middle position of the length direction of the outer frame 12, and in this embodiment is exactly located at the connection position between the outer frame 12 and one of the partitions 13. The connecting frame 16 is connected to the outer frame 12 at two places in the horizontal direction, and is fixed to the surface of the outer frame 12 away from the installation space through the rivet hole 125 and the rivet protrusion 131; the connecting frame 16 is connected to the outer frame 12 at one place in the height direction, where the connecting frame 16 is provided with a rivet hole 125, and is connected to the outer frame 12 through a rivet. The outer frame 12, the partition 13, the connecting frame 16, etc. of this embodiment are all made of sheet metal materials, so there are three layers of sheet metal materials at the position where the connecting frame 16 is fixed by rivets, thereby increasing the connection strength of the connecting frame 16, ensuring the stability of the fixing pin, and thus ensuring the opening and closing strength of the upper cover of the server chassis 40. The fixing pin is cylindrical and is set along the height direction of the outer frame 12, so as to facilitate connection with the upper cover of the server.

[0070] like Fig.13 As shown, in this embodiment, the fan assembly 10 also includes a honeycomb mesh cover 15, the outer frame 12 has ventilation holes, and the honeycomb mesh cover 15 is covered at the ventilation holes, so as to guide the fan 14, thereby improving the uniformity of the airflow of the fan 14, and further helping to improve the reliability and effectiveness of the hard disk. Specifically, the honeycomb mesh cover 15 is set in a rectangular shape, the same size as the side of the length direction of the outer frame 12, and the edges of the long sides of the honeycomb mesh cover 15 are provided with riveted ball screws and buckle structures, so as to achieve fixation with the outer frame 12. The honeycomb mesh cover 15 of this embodiment includes a cover body, a sub-honeycomb mesh cover, and a honeycomb net, wherein the number of the sub-honeycomb mesh cover and the honeycomb net is adjusted according to the number of fans 14 in the fan module, the honeycomb net is located between the cover body and the sub-honeycomb mesh cover, and the sub-honeycomb mesh cover is buckled on the cover body through the buckle structure, so as to fix the honeycomb net, and the cover body is set in a rectangle with the same size as the side of the length direction of the outer frame 12, and is connected to the outer frame 12 through the buckle structure. The fans 14 of this embodiment are set to six, so the sub-honeycomb mesh covers and honeycomb nets of this embodiment are both set to six. In this way, the airflow blown by the fan 14 can be straightened through the honeycomb mesh cover 15, and the large-sized vortices in the airflow can be divided into small-sized vortices, thereby reducing the turbulence of the airflow, making the airflow velocity evenly distributed, achieving a shock-absorbing effect, and thus improving the read and write performance of the server hard disk. It should be noted that the honeycomb mesh of this embodiment is a hexagonal honeycomb structure, similar to an I-beam structure. This structure can improve the rigidity and stability of the honeycomb, can bear the pressure in the direction of the cover body, make it evenly stressed, and not easy to deform, thereby greatly ensuring the flatness of the honeycomb mesh cover 15.

[0071] The fan assembly 10 of this embodiment further includes a positioning post 121 for positioning with the server chassis 40. The positioning post 121 is detachably disposed at the bottom of the outer frame 12 and extends downward, thereby ensuring that the fan assembly 10 is accurately installed in the server chassis 40, thereby avoiding problems such as plug-in failure or reduced heat dissipation efficiency caused by inaccurate installation position. Fig.14 As shown, the positioning column 121 of this embodiment is configured as a square column, and a screw is provided at the top of the positioning column 121, that is, the end of the positioning column 121 close to the bottom of the outer frame 12, so as to facilitate connection and removal with the server chassis 40. In this way, when the positioning column 121 loses its strength due to long-term use, the positioning column 121 can be replaced by simply removing the screws.

[0072] It should be noted that the outer frame 12 of this embodiment is located above the server mainboard, and the height space between the outer frame 12 and the mainboard can be used for wiring.

[0073] The fan assembly 10 of this embodiment further includes an elastic member, which is disposed in the installation space and between the inner wall of the outer frame 12 and the fan 14, so that the elasticity of the elastic member can assist in disassembling the fan 14. Optionally, the elastic member of this embodiment is configured as a small-sized spring, which is pasted on the bottom of the outer frame 12, so that it can facilitate the disassembly of the fan 14 without affecting the installation of the fan 14, and can absorb the vibration generated when the fan 14 is running, thereby reducing noise and improving the stability of the server operation.

[0074] In the present embodiment, the fan 14 includes a fan body 141 and an inner frame 142. The inner frame 142 is located in the sub-space. The inner frame 142 includes a plurality of sub-frames. The sub-frames are docked to form a mounting cavity for accommodating the fan body 141. The sub-frames and the fan body 141 both have a docking structure for docking. After the fan body 141 is connected to the sub-frame through the docking structure, the sub-frames are docked together, thereby ensuring the safety of the fan body 141, while ensuring the flexibility of the assembly of the fan body 141 and the inner frame 142 and the connection strength of the two. Specifically, the docking structure includes a connecting hole of the fan body 141 and a hook-shaped structure of the inner frame 142. The fan body 141 of the present embodiment is a cylinder, but the upper and lower bottom surfaces of the cylinder are set to a rectangle, and connecting holes are set at the four corners of the rectangle. Along the height direction of the cylinder, that is, the width direction of the outer frame 12, hook-like structures extend into the installation cavity at the four corners of the inner frame 142. The hook-like structures can extend into the connecting holes of the fan body 141 and limit the position of the fan body 141 through the hook-like structures, thereby fixing the position of the fan body 141 in the installation cavity.

[0075] In this embodiment, the inner frame 142 includes a first sub-frame and a second sub-frame, and the first sub-frame and the second sub-frame are both configured as two rectangular plates connected to each other, and a rectangular plate of the first sub-frame and a rectangular plate of the second sub-frame are respectively configured as hollow mesh structures, and are respectively arranged at the air inlet and the air outlet of the fan body 141, so as to provide support for the fan body 141 without affecting the suction and blowing of the fan body 141. Another rectangular plate of the first sub-frame and another rectangular plate of the second sub-frame are adjacent to each other and are arranged vertically, wherein another rectangular plate of the first sub-frame is provided with a clamping portion 143 and a handle, and another rectangular plate of the second sub-frame is provided with a notch to avoid the handle, so as to realize the rapid assembly and disassembly of the fan 14 and the partition 13. The adjacent edges of the first sub-frame and the second sub-frame are both provided with a buckle structure, so that when the fan 14 is placed in the installation cavity, the first sub-frame and the second sub-frame can be clamped together through the buckle structure, so that the sub-frames enclose the fan body 141, improving the aesthetics. The position of the snap structure between the first sub-frame and the second sub-frame is not limited, as long as the two can be reliably connected. Preferably, the inner frame 142 also includes a baffle structure, which is arranged at the edges of the first sub-frame and the second sub-frame that are not adjacent to each other to achieve connection and fixation with the fan body 141.

[0076] like Fig.11 , Fig.15As shown, in this embodiment, the fan 14 also includes a terminal 144, the terminal 144 has a protrusion, the bottom of the inner frame 142 has a terminal mounting structure 145, the bottom of the terminal mounting structure 145 has a hook structure 1451 extending laterally and protruding upward, the top of the terminal mounting structure 145 has a fixing hole 1452, when the terminal 144 is installed in the terminal mounting structure 145, the side of the terminal 144 abuts against the hook structure 1451, and the protrusion of the terminal 144 extends into the fixing hole 1452, thereby fixing the terminal 144 to the inner frame 142, preventing the terminal 144 from moving or even falling, so that the terminal 144 has an anti-disassembly function. Specifically, a part of the terminal 144 is located inside the installation cavity to achieve connection with the fan body 141 and fixation with the inner frame 142, and the other part is located outside the installation cavity to achieve connection with the server chassis 40 or other components. The hook structure 1451 of the terminal mounting structure 145 extends horizontally toward the center of the mounting cavity, and one end of the hook structure 1451 near the center of the mounting cavity has a hook protruding toward the inside of the mounting cavity, thereby limiting the portion of the terminal 144 inside the mounting cavity within the extension range of the hook structure 1451. There are two hook structures 1451, which are arranged in parallel and are both located at the bottom of the portion of the terminal 144 inside the mounting cavity. A fixing hole 1452 is arranged above the hook structure 1451 closer to the center of the mounting cavity. In this way, after the terminal 144 is inserted into the hook structure 1451, the fixing hole 1452 cooperates with the protrusion of the terminal 144 to further fix the terminal 144, thereby preventing the terminal 144 from falling off. The terminal 144 of this embodiment adopts a customized terminal, which is small in size and has a small insertion and removal force, and is easy to insert and remove the fan 14.

[0077] The assembly process of the fan 14 of this embodiment is as follows: first, the fan body 141 is installed in the first sub-frame, and the fan body 141 is fixed in the first sub-frame by using four hook structures to cooperate with the connection holes at one end of the fan body 141. After the fan body 141 is installed in the first sub-frame, the terminal 144 is clamped into the terminal mounting structure 145, and the terminal 144 is fixed by using the hook structure 1451 of the terminal mounting structure 145, and the terminal 144 is prevented from falling by using the fixing hole 1452 to cooperate with the protrusion of the terminal 144. Then the second sub-frame is installed, and the first sub-frame and the second sub-frame have two adjacent edges, and one of the adjacent edges is clamped by using the buckle structure between the first sub-frame and the second sub-frame, and the hook structure 1451 of the second sub-frame cooperates with the connection hole at the other end of the fan body 141, and the baffle structure cooperates with the fan body 141. After the fan body 141 is installed in place, the other adjacent edge is clamped by using the buckle structure between the first sub-frame and the second sub-frame, thereby completing the assembly of the fan 14.

[0078] like Fig.16As shown, in this embodiment, the fan 14 also includes an extension piece 147, which is detachably connected to the end of the fan body 141 and can be docked with the inner frame 142, so that the inner frame 142 can be compatible with various types of fan bodies 141. Specifically, the extension piece 147 of the present embodiment is configured to be a cylindrical shape similar to the fan body 141, but the upper and lower bottom surfaces of the cylinder are configured to be rectangular, and one of the bottom surfaces is snap-fitted with the bottom surface of the fan body 141. When the fan body 141 can be snap-fitted with the inner frame 142, the extension piece 147 is not installed. When the length of the fan body 141 along the axis of the cylinder is small, resulting in the upper and lower bottom surfaces of the fan body 141 being unable to be snap-fitted with the inner frame 142, the extension piece 147 can be snap-fitted to the bottom surface of the fan body 141, thereby achieving the snap-fitting of the fan body 141 and the inner frame 142. In this way, a plurality of different types of fan bodies 141 can share the same set of inner frames 142, and can quickly switch between fans 14 of different models, thereby improving the flexibility and adaptability of the fan assembly 10 and facilitating cost savings.

[0079] In the present embodiment, the fan 14 also includes a shock-absorbing member, which is arranged between the fan body 141 and the inner frame 142, so as to reduce the vibration of the fan body 141 when it is working. The shock-absorbing member of the present embodiment is arranged at the hook-shaped structure of the inner frame 142. When the hook-shaped structure extends into the connecting hole of the fan body 141, the fan body 141 and the inner frame 142 respectively abut against different sides of the shock-absorbing member, thereby playing a shock-absorbing role. Optionally, the shock-absorbing member of the present embodiment adopts a shock-absorbing rubber ring, which is sleeved on the outer peripheral side of the hook-shaped structure. Of course, according to actual conditions, the shock-absorbing member and the hook-shaped structure of the inner frame 142 may not be provided, and the inner frame 142 and the fan body 141 may be directly fixed together using fan glue nails.

[0080] In this embodiment, the fan 14 also includes a light guide column for indicating the state of the fan 14. The light guide column is arranged on the inner frame 142 and is electrically connected to the fan body 141, so as to display the working state of the fan body 141, which is easy for the operator to identify. The light guide column of this embodiment is arranged on the surface of the inner frame 142 away from the fan body 141, that is, the outer surface of the inner frame 142, and a mounting groove is provided on the outer surface of the inner frame 142. When installing the light guide column, it is only necessary to slide the light guide column into the mounting groove. The installation is simple and convenient and easy to fix. In this way, when the fan body 141 is identified as having a fault, the fan body 141 that has reported an error can be displayed through the light guide column, so that it is easy to identify, and the state of the fan body 141 can be determined without disassembling the inner frame 142.

[0081] In this embodiment, the fan 14 further includes an indicator mark 146, which is located on the surface of the inner frame 142 exposed to the outer frame 12, so that the various parts of the fan 14 are easier to identify. Specifically, the indicator mark 146 includes the serial number of the fan body 141, the wind direction mark, etc. For example, the serial number of the fan body 141 can be silk-screened on the inner frame 142, marked from left to right, so that it is easy to identify; the wind direction mark and the fan efficiency mark can also be engraved on the top of the inner frame 142; and a blue operation mark can also be silk-screened on the top of the handle of the inner frame 142 for easy identification by operators.

[0082] like Figure 1 As shown, the present embodiment further provides a server, including a server chassis 40 and the above-mentioned fan module for the server, the fan module is located in the server chassis 40, the server chassis 40 includes a mounting frame 41, the mounting frame 41 has a locking portion 411, when the fan module is connected to the server chassis 40, the locking portion 411 is docked with the docking portion 11 of the fan module, and is limitedly matched with the operating member 20 of the fan module, thereby not only ensuring the stable installation of the fan module in the server chassis 40, but also simplifying the disassembly and assembly process of the fan module, thereby improving the maintenance efficiency of the server, thereby improving the operating stability and convenience of maintenance of the server. Specifically, the mounting frame 41 is configured as a plate-like structure, and the mounting frame 41 is arranged parallel to the first side plate 127. A locking portion 411 is arranged on the side of the mounting frame 41 facing the docking portion 11, and the locking portion 411 is configured as a cylindrical pin. The axial direction of the cylindrical pin is perpendicular to the surface of the mounting frame 41, so that the cylindrical pin can extend into the avoidance notch 112 of the docking portion 11 and extend into the limiting channel 21 of the operating member 20, thereby realizing docking cooperation with the docking portion 11 and limiting cooperation with the operating member 20, so that the entire fan module can be slid in and out by simply rotating the operating member 20, without the need for other tools, thereby realizing quick installation and disassembly of the fan assembly 10.

[0083] In this embodiment, similar to the connection between the partition 13 and the outer frame 12, the connection between the mounting frame 41 and other parts of the server chassis 40 is also fixed by connecting the rivet protrusions 131 and the rivet holes 125, thereby reducing the use of hardware.

[0084] In this embodiment, a guide structure is provided between the mounting frame 41 and the docking portion 11 of the fan module, and the guide structure includes a guide protrusion 412 and a guide slide 111. One of the mounting frame 41 and the docking portion 11 has a guide protrusion 412, and the other of the mounting frame 41 and the docking portion 11 has a guide slide 111. The guide protrusion 412 is slidably provided in the guide slide 111, so that the fan assembly 10 can be moved closer to and farther from the server chassis 40 along the extension direction of the guide slide 111 during installation and removal, thereby realizing the tool-free insertion and sliding out of the entire fan module from the server chassis 40. Specifically, as Fig.17 As shown, the mounting frame 41 of this embodiment is provided with a guide protrusion 412, and the docking portion 11 is provided with a guide slide 111. The guide protrusion 412 is provided on one side of the mounting frame 41 close to the docking portion 11 and protrudes toward the docking portion 11. The guide slide 111 is also the slide groove of the docking portion 11. In this way, through the relative sliding of the guide protrusion 412 and the guide slide 111, on the one hand, the fan assembly 10 can be installed and disassembled along the extension direction of the guide slide 111, thereby improving the reliability of the installation and disassembly of the fan assembly 10. On the other hand, the use of hardware such as I-shaped nails can be reduced, thereby reducing costs. The setting positions of the guide protrusion 412 and the guide slide 111 of this embodiment can be swapped without affecting the use effect. That is to say, the guide slide 111 can also be provided on the mounting frame 41, and the guide protrusion 412 can be provided on the docking portion 11, which can also play a guiding role. Of course, the connection between the mounting frame 41 and the docking portion 11 may also adopt other structural forms, or a structural form in which a stud and a guide hole cooperate, which can also achieve the purpose of guidance.

[0085] In this embodiment, the server chassis 40 also includes an intrusion switch. Compared with the traditional fixing method of fixing the intrusion switch to the inner frame 142 of the fan 14 or the inner part of the outer frame 12, this embodiment fixes the intrusion switch to the side wall of the server chassis 40. The gap between the upper cover of the server chassis 40 is easy to control, and the intrusion switch is not easy to trigger a false alarm. Moreover, the intrusion switch is detached from the inner frame 142 of the fan 14 or the inner part of the outer frame 12, which reduces the volume of the fan module and makes the arrangement of the fan 14 more compact, which is conducive to saving space. Of course, the intrusion switch can also be set on the outside of the outer frame 12, that is, on the side surface of the outer frame 12 away from the installation space, which is also conducive to compact installation between fans 14 and preventing false alarms. Preferably, a wire buckle for fixing the intrusion switch can be pasted on the bottom of the outer frame 12 to improve its safety.
