Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of servers, and particularly relates to a heat dissipation device, a heat dissipation module and a server. BACKGROUND

[0002] At present, the heat dissipation fan module is an important component of a server system, which is mainly used for improving the heat dissipation reliability of the server system, realizing efficient heat management of the server system, and maintaining the stable operation of the server system, so that the staff needs to frequently maintain the fan device in the heat dissipation fan module in the daily work process to ensure the overall effective operation of the heat dissipation fan module, and in this process, it is inevitable to use tools to disassemble and replace the fan device in the heat dissipation fan module.

[0003] In the prior art, with the increase of high-U server storage configuration and board card expansion configuration, the operation heat of the server system gradually increases, in order to ensure that the server heat dissipation system has high enough heat dissipation reliability, the staff usually sets more fan devices in the heat dissipation fan module, and the corresponding arrangement mode of the fan devices becomes more complex and dense.

[0004] However, the above setting mode and the traditional fan device fixing mode (such as fasteners) will increase the difficulty and reduce the efficiency of the staff in maintenance and disassembly, and waste human resources. SUMMARY

[0005] The present application provides a heat dissipation device, a heat dissipation module and a server to at least solve the problem of high maintenance difficulty of the server heat dissipation module in the related art.

[0006] The present application provides a heat dissipation device, comprising: a heat dissipation assembly, comprising a shell and a clamping structure, the clamping structure is used for clamping cooperation with a cooperation part of a heat dissipation module to fix the heat dissipation assembly, the shell comprises an elastic mounting piece for mounting the clamping structure; an operation structure, comprising a connecting piece and an operating piece, the connecting piece is rotatably arranged on the shell, and the operating piece is arranged on the connecting piece to rotate around the shell through the connecting piece; wherein the connecting piece and the elastic mounting piece are located on the same side of the shell, and at least part of the elastic mounting piece is located in the rotating range of the connecting piece, when the operating piece is rotated to an operating position above the shell, at least part of the connecting piece is in abutting cooperation with the elastic mounting piece, so that the elastic mounting piece is elastically deformed towards the side away from the cooperation part to drive the clamping structure to separate from the cooperation part; when at least part of the operating piece is rotated to a storage position on one side of the shell, the connecting piece avoids the elastic mounting piece, and the elastic mounting piece restores the elastic deformation to drive the clamping structure to be in clamping cooperation with the cooperation part.

[0007] The application further provides a heat dissipation module, comprising: a shell comprising a shell body and a mounting frame, the shell body having a setting cavity, the mounting frame being detachably arranged in the setting cavity through a clamping assembly, the mounting frame having a matching part; and a heat dissipation device, a clamping structure of the heat dissipation device being clamped and matched with the matching part to be fixed in the mounting frame; wherein the heat dissipation device is the heat dissipation device described above.

[0008] The application further provides a server comprising the heat dissipation module described above.

[0009] Compared with the fixing mode of the conventional heat dissipation device, the heat dissipation assembly of the heat dissipation device in the application is only fixed through the clamping structure, and an operation structure is additionally arranged to facilitate the staff to carry and transport the disassembled heat dissipation device, thereby preliminarily reducing the maintenance difficulty of the staff. In addition, the operation structure and the clamping structure are designed to be linked, that is, when the staff rotates the operation piece to the operating position above the shell to prepare for the carrying operation, the connecting piece will abut against the elastic mounting piece in the rotating range of the operation piece during the rotation of the operation piece to drive the elastic mounting piece to elastically deform, so as to realize the clamping separation between the clamping structure and the matching part. In other words, when the staff rotates the operation piece to the operating position, the heat dissipation assembly has been separated from the heat dissipation module. It can be seen that the heat dissipation device in the application does not need to use any tool for assistance during actual maintenance and disassembly, and the operation is extremely simple, which greatly reduces the maintenance difficulty of the staff, thereby solving the problem of large maintenance difficulty of the server heat dissipation module in the related art, and improving the maintenance efficiency of the staff. At the same time, when the operation piece is rotated to the storage position, the connecting piece can avoid the elastic mounting piece under the driving of the operation piece, not only realizing the re-clamping of the clamping structure to facilitate the staff to install the heat dissipation device, but also reducing the space occupation range of the operation piece, which is conducive to realizing the miniaturization design of the heat dissipation module.

[0034] In order for those skilled in the art to better understand the scheme of the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0035] The embodiments of the present application provide a heat dissipation device, a heat dissipation module and a server, wherein the server and the heat dissipation module both comprise the heat dissipation device described below, and the heat dissipation device is described in detail in combination with the structure and function of the heat dissipation device.

[0036] As Figures 1 to 4As shown, the heat dissipation device includes a heat dissipation assembly and an operation structure 30, the heat dissipation assembly includes a shell 10 and a clamping structure 20, the clamping structure 20 is used for clamping cooperation with the matching part 221 of the heat dissipation module to fix the heat dissipation assembly, the shell 10 includes an elastic mounting piece 11 for mounting the clamping structure 20. The operation structure 30 includes a connecting piece 31 and an operating piece 32, the connecting piece 31 is rotatably arranged on the shell 10, and the operating piece 32 is arranged on the connecting piece 31 to rotate around the shell 10 through the connecting piece 31. Among them, the connecting piece 31 and the elastic mounting piece 11 are located on the same side of the shell 10, at least part of the elastic mounting piece 11 is located in the rotating range of the connecting piece 31, when the operating piece 32 rotates to the operating position located above the shell 10, at least part of the connecting piece 31 abuts with the elastic mounting piece 11 to make the elastic mounting piece 11 elastically deform towards the side away from the matching part 221, so as to drive the clamping structure 20 to separate from the matching part 221; when at least part of the operating piece 32 rotates to the storage position located on one side of the shell 10, the connecting piece 31 avoids the elastic mounting piece 11, and the elastic mounting piece 11 restores the elastic deformation to drive the clamping structure 20 to clamp with the matching part 221.

[0037] Compared with the fixing mode of the traditional heat dissipation device, the heat dissipation assembly of the heat dissipation device 100 in the embodiment is only fixed by the clamping structure 20, and the operation structure 30 is additionally arranged to facilitate the staff to carry and transport the disassembled heat dissipation device 100, thereby preliminarily reducing the maintenance difficulty of the staff. In addition, the operation structure 30 and the clamping structure 20 are designed to be linked, that is, when the staff rotates the operating piece 32 to the operating position located above the shell 10 to prepare for the carrying operation, the connecting piece 31 will abut with the elastic mounting piece 11 located in the rotating range thereof during the rotation driven by the operating piece 32 to drive the elastic mounting piece 11 to elastically deform, so as to realize the clamping separation between the clamping structure 20 and the matching part 221. In other words, when the staff rotates the operating piece 32 to the position, the heat dissipation assembly has been separated from the heat dissipation module. It can be seen that the heat dissipation device in the embodiment does not need to use any tool for assistance during actual maintenance and disassembly, and the operation is extremely simple, which greatly reduces the maintenance difficulty of the staff, thereby solving the problem of large maintenance difficulty of the server heat dissipation module in the related art, and improving the maintenance efficiency of the staff. At the same time, when the operating piece 32 rotates to the storage position, the connecting piece 31 can avoid the elastic mounting piece 11 under the driving of the operating piece 32, not only realizes the re-clamping of the clamping structure 20, but also facilitates the staff to install the heat dissipation device 100, and can reduce the space occupation range of the operating piece 32, which is conducive to realizing the miniaturization design of the heat dissipation module.

[0038] Optionally, the clamping structure 20 is a clamping hook, and the matching part 221 is a corresponding clamping hole or recess, and the structure between the two can also be replaced with each other, and the specific structure is relatively simple and will not be described here.

[0039] Specifically, the linkage design between the operating structure 30 and the elastic mounting member 11 in the embodiment can also prolong the service life of the clamping structure 20. Specifically, during the adjustment of the assembly position of the heat dissipation device 100 by the worker, the clamping hook is rubbed with the inner wall surface of the heat dissipation module, which causes the hook tip to wear and flatten, and the clamping stability to deteriorate. In the embodiment, the heat dissipation device 100 is arranged to make the operating member 32 in the operating position when the assembly position is adjusted, that is, the clamping hook is in the clamping separation position under the action of the elastic mounting member 11, so as to reduce the friction (or even no friction) between the clamping hook and the inner wall surface of the heat dissipation module, thereby prolonging the service life of the clamping structure 20.

[0040] Specifically, the elastic mounting member 11 is partially located in the rotation coverage range of the connecting member 31, so as to ensure that the elastic mounting member 11 can be abutted with the connecting member 31 during the rotation of the connecting member 31.

[0041] As shown in Figure 1 and Figure 2 , the elastic mounting member 11 includes a main body part 111 and a guide protrusion 112, and the guide protrusion 112 and the clamping structure 20 are arranged on the main body part 111. At least part of the guide protrusion 112 is located on the rotation path of the connecting member 31, so as to be abutted with the connecting member 31. After the connecting member 31 abuts the guide protrusion 112, the connecting member 31 slides along the outer surface of the guide protrusion 112, so as to push the guide protrusion 112 to drive the main body part 111 to elastically deform towards the side away from the matching part 221. In this way, the above arrangement ensures that the connecting member 31 can push the main body part 111 to elastically deform in the form of pushing, so as to realize the clamping separation action through the abutment and sliding action between the outer surface of the guide protrusion 112 protruding from the main body part 111 and the connecting member 31.

[0042] In the embodiment, the main body part 111 is an elastic structure.

[0043] Specifically, during the rotation switching of the operating member 32 between the operating position and the storage position and the rotation of the connecting member 31, at least part of the guide protrusion 112 is located in the rotation plane formed by the connecting member 31. After the connecting member 31 is rotated to abut the guide protrusion 112, if the connecting member 31 continues to rotate, since the main body part 111 is an elastic structure, the connecting member 31 will slide along the outer surface of the guide protrusion 112 and push the guide protrusion 112 to drive the main body part 111 to elastically deform, and the main body part 111 further drives the clamping structure 20 to move, so as to separate the clamping structure 20 from the matching part 221. As shown inFigure 1 and Figure 2 As shown in Figure 2 , the side of the housing 10 where the elastic mounting member 11 is provided is the mounting surface 12. The guiding convex portion 112 has a guiding inclined surface 1121, and the guiding inclined surface 1121 abuts against the connecting member 31. Among them, along the moving direction in which the connecting member 31 pushes the main body portion 111 to elastically deform, the distance between the guiding inclined surface 1121 and the mounting surface 12 gradually increases. In this way, the setting of the guiding inclined surface 1121 can ensure that the abutting and sliding actions between the connecting member 31 and the guiding convex portion 112 are smoother, effectively avoiding the problem of action jamming, and further reducing the disassembly and assembly difficulty of the staff.

[0044] In this embodiment, the main body portion 111 is integrally plate-shaped, and the guiding convex portion 112 is a wedge-shaped block structure provided on the plate surface of the main body portion 111, and its inclined surface forms the guiding inclined surface 1121.

[0045] In this embodiment, the moving direction in which the connecting member 31 pushes the main body portion 111 to elastically deform is the rotation direction S.

[0046] As Figure 1 and Figure 2 shown, the main body portion 111 is plate-shaped, and the housing 10 further includes a housing main body 13. The housing main body 13 has a mounting cavity 131 and a mounting hole 132 communicating with the mounting cavity 131. One end of the main body portion 111 is provided on the hole wall of the mounting hole 132 to form at least part of the housing 10. Among them, when the connecting member 31 abuts against the guiding convex portion 112 to push the main body portion 111 to elastically deform, at least part of the main body portion 111 moves toward the mounting cavity 131. In this way, the above setting makes the structure of the main body portion 111 simpler, and uses the mounting cavity 131 to provide a避让 space for the main body portion 111 to elastically deform, which is beneficial to the miniaturized design of the housing main body 13.

[0047] In this embodiment, the connecting member 31 abuts against the guiding inclined surface 1121 of the guiding convex portion 112.

[0048] In this embodiment, the main body portion 111 is a rectangular plate structure.

[0049] It can be understood that the plate-shaped main body portion 111 provided in the mounting hole 132 in this embodiment can also be directly formed by machining a "凵"-shaped strip hole on the surface of the housing main body 13, so that the formation of the main body portion 111 is simpler and easier to be machined and realized.

[0050] It can be understood that only one side of the plate-shaped main body portion 111 in this embodiment is connected to the hole wall of the mounting hole 132, and the connection part has a weak rigidity and has a certain elastic deformation ability.

[0051] It should be noted that the material of the main body 111 can also be optimized and designed, and a material with a higher elastic coefficient can be used to ensure that it has higher elastic deformation reliability.

[0052] In the embodiment, the shell body 13 is a cuboid structure.

[0053] In the embodiment, the connecting piece 31 is rotatably arranged on one side of the shell body 13. When the operating piece 32 is rotated to the operating position, the operating piece 32 is located above the shell body 13. When the operating piece 32 is rotated to the storage position, the operating piece 32 is located on one side of the side adjacent to the side on which the connecting piece 31 is arranged.

[0054] As shown in Figure 1 and Figure 2 The mounting surface 12 is provided with a connecting portion 14. The connecting piece 31 is rotatably arranged on the shell 10 through the connecting portion 14. The guide convex portion 112 is located between the connecting portion 14 and the clamping structure 20. The connecting portion 14 is arranged close to the top of the shell 10 relative to the guide convex portion 112. The connecting piece 31 is plate-shaped and includes a connecting segment 311 and a matching segment 312 connected to each other. The rotation axis of the connecting piece 31 is located between the connecting segment 311 and the matching segment 312. The connecting segment 311 is used to connect the operating piece 32. The matching segment 312 is used to abut against the guide convex portion 112. The length of the matching segment 312 is less than the length of the connecting segment 311. In this way, the above arrangement enables the connecting segment 311 and the matching segment 312 to form a lever structure with the rotation axis as the fulcrum. That is, after the operating piece 32 drives the connecting piece 31 to rotate to abut against the guide convex portion 112, only a small force is needed to ensure that the connecting piece 31 pushes the main body 111 to elastically deform (also because in the carrying state, the heat dissipation assembly naturally hangs down and will not rotate under the elastic force of the main body 111, which facilitates the staff to carry and place).

[0055] It should be noted that the arrangement of the connecting piece 31, the connecting portion 14, and the guide convex portion 112 is not limited to this. For example, the connecting piece 31 is only provided with the connecting segment 311. The guide convex portion 112 is arranged close to the top of the shell 10 relative to the connecting portion 14 to directly abut against the guide inclined surface 1121 of the guide convex portion 112 through the connecting segment 311. This can also achieve the linkage action as described above (correspondingly, the movement direction of the connecting piece 31 pushing the main body 111 to elastically deform is the opposite direction of the rotation direction S).

[0056] In the embodiment, the elastic mounting piece 11, the clamping structure 20, and the mounting hole 132 are all two. The mounting holes 132 are arranged on the opposite two sides of the shell body 13. That is, the shell body 13 can improve the clamping and fixing stability through the two clamping structures 20.

[0057] In the embodiment, the connecting member 31 is also two, the operating member 32 is a rod, and one connecting member 31 is connected to each end of the operating member 32. The two connecting members 31 are arranged correspondingly to the two elastic mounting members 11 to realize the linkage action between the two clamping structures 20 and the operating structure 30.

[0058] In the embodiment, the connecting portion 14 is a through hole, and the rotating shaft 34 is arranged at the rotating axis of the connecting member 31. The rotating shaft 34 is rotatably arranged in the connecting portion 14 to realize the rotating action of the connecting member 31.

[0059] In the embodiment, the mounting recess 16 is arranged at the connecting portion 14, that is, the connecting portion 14 is arranged on the bottom wall of the mounting recess 16, and part of the main body portion 111 is arranged in the mounting recess 16 to form the bottom wall of the mounting recess 16 by the plate surface. The guide protrusion 112 is arranged on the part of the main body portion 111 that forms the bottom wall of the mounting recess 16, that is, the arrangement surface of the guide protrusion 112 (the bottom wall of the mounting recess 16) is lower than the mounting surface 12 in the direction perpendicular to the mounting surface 12. Meanwhile, the fitting section 312 protrudes towards the mounting surface 12 relative to the connecting section 311, so that part of the fitting section 312 is arranged in the mounting recess 16 to cooperate with the guide protrusion 112. The clamping structure 20 is directly arranged on the mounting surface 12 to form a height difference with the guide protrusion 112 in the direction perpendicular to the mounting surface 12. The above arrangement ensures reasonable arrangement of the structure to improve the smoothness of the linkage action, and reduces the protruding height of the connecting member 31, the clamping structure 20 and the guide protrusion 112 relative to the mounting surface 12, which is beneficial to miniaturization design of the heat dissipation device.

[0060] As shown in Figure 1 and Figure 2 The operating structure 30 has the first clamping portion 33, and the shell 10 has the second clamping portion 15. When the operating member 32 is rotated to the storage position, the first clamping portion 33 cooperates with the second clamping portion 15 to fix the operating structure 30. In this way, the above arrangement further fixes the operating structure 30 in the storage position, which is convenient for the staff to store or install the heat dissipation device 100.

[0061] In the embodiment, the first clamping portion 33 is a protrusion, and the second clamping portion 15 is a groove structure arranged on the outer edge of the shell main body 13. When the protrusion is deeply arranged in the groove structure, the operating structure 30 is fixed by the limiting stop between the protrusion and the inner wall of the groove structure.

[0062] It should be noted that the structure of the first clamping portion 33 and the second clamping portion 15 can be replaced with each other.

[0063] In the embodiment, the first clamping part 33 is arranged on the surface of the connecting piece 31 facing the shell body 13, and the second clamping part 15 is arranged on the outer surface of the shell body 13.

[0064] In the embodiment, the first clamping part 33 is arranged on the surface of the connecting piece 31 facing the shell body 13, and the second clamping part 15 is arranged on the outer surface of the shell body 13.

[0065] The specific linkage action between the operation structure 30 and the elastic mounting piece 11 in the embodiment is as follows:

[0066] In the process of the staff operating the operation piece 32 to rotate to the operation position, the operation piece 32 synchronously drives the connecting piece 31 to rotate, until the connecting segment 311 of the connecting piece 31 moves to abut against the guide slope 1121, under the guiding action of the guide slope 1121, the connecting segment 311 that continues to rotate will push the guide protrusion 112 to drive the main body 111 and the clamping structure 20 located on the main body 111 to move towards the installation cavity 131, until the operation piece 32 completely moves to the operation position (perpendicular to the top surface of the shell body 13), the clamping structure 20 and the matching part 221 are completely clamped and separated, at this time, directly taking can realize the disassembly of the fan device. When the staff operates the operation piece 32 to rotate to the storage position (horizontal), the matching segment 312 of the connecting piece 31 is separated from the guide slope 1121, the main body 111 restores the elastic deformation to drive the clamping structure 20 located thereon to reset, thereby realizing the clamping cooperation.

[0067] In the embodiment, the shell body 13 also has an air inlet 133 and an air outlet 134 that are in communication with the installation cavity 131, the air inlet 133 is in communication with the air outlet 134 through the installation cavity 131; the heat dissipation assembly also includes a plurality of fan structures 40, the plurality of fan structures 40 are arranged in the installation cavity 131 along the length direction and / or the width direction and / or the height direction of the shell body 13, the fan structure 40 is used for driving airflow to flow, so as to form a heat dissipation airflow between the air inlet 133 and the air outlet 134. In this way, the arrangement of the plurality of fan structures 40 increases the heat dissipation performance of the heat dissipation assembly, so as to match the server with higher heat dissipation demand, and at the same time, the synchronous disassembly of the plurality of fan structures 40 can be realized, that is, the staff can realize the synchronous disassembly of the plurality of fan structures 40 and subsequent maintenance while disassembling one heat dissipation device 100, which greatly reduces the maintenance difficulty of the staff and improves the maintenance efficiency of the staff.

[0068] In the embodiment, the fan structure 40 is two, and the two fan structures 40 are arranged in the height direction of the shell body 13.

[0069] In the embodiment, the air inlet 133 and the air outlet 134 are both two, the two air inlets 133 are arranged in one-to-one correspondence with the two fan structures 40, and the two air outlets 134 are arranged in one-to-one correspondence with the two fan structures 40, so as to realize independent air inlet and air outlet of each fan structure 40, reduce the probability of turbulence, and further improve the heat dissipation reliability of the heat dissipation device 100.

[0070] It should be noted that the number of fan structures 40 is not limited to this, and can be adjusted according to the working condition and use demand.

[0071] As shown in Figure 1 , Figure 3 and Figure 4 , the shell body 13 includes a first sub-shell 135 and a second sub-shell 136, the first sub-shell 135 has a third clamping portion 1351. The second sub-shell 136 has a fourth clamping portion 1361, and the first sub-shell 135 is detachably connected through the clamping cooperation between the third clamping portion 1351 and the fourth clamping portion 1361, and an installation cavity 131 is formed around the first sub-shell 135 and the second sub-shell 136. In this way, the above arrangement can facilitate the further disassembly of the shell body 13 by the worker, so as to facilitate the maintenance of the fan structure 40 in the shell body 13, thereby reducing the maintenance difficulty of the worker and improving the maintenance efficiency of the worker.

[0072] In the embodiment, the third clamping portion 1351 is a clamping recess, and the fourth clamping portion 1361 is a clamping hook structure.

[0073] It should be noted that the structures of the third clamping portion 1351 and the fourth clamping portion 1361 can also be replaced with each other.

[0074] In the embodiment, the first sub-shell 135 includes three plate-shaped members connected in sequence and arranged in a whole "N" shape, and the second sub-shell 136 is a cover-shaped structure. The third clamping portion 1351 is arranged on the two oppositely arranged plate-shaped members of the first sub-shell 135, and the fourth clamping portion 1361 is arranged on the end face of the surrounding plate of the second sub-shell 136.

[0075] In the embodiment, the first sub-shell 135 is provided with an air outlet 134 and a first through hole on the plate-shaped member between the two oppositely arranged plate-shaped members, and the first through hole is arranged in a spaced manner with the air outlet 134. The shell body 13 further includes a fastener 139, and the fan structure 40 and the first through hole are provided with the fastener 139, so as to preliminarily fix the fan structure 40 on the first sub-shell 135.

[0076] In the embodiment, the first mounting plate 137 is further provided on the end face of the second sub-housing 136, and the second through hole is provided on the first mounting plate 137. The fastener 139 is also provided on the second through hole and the fan structure 40, so as to further fix the fan structure 40 on the second sub-housing 136.

[0077] In the embodiment, the fastener 139 is actually a rubber pin, which can play the effects of shock absorption, buffering and shock energy absorption while achieving the fixation of the fan structure 40, so as to effectively reduce the noise generated in the operation of the fan structure 40.

[0078] As shown in Figure 1 , Figure 3 and Figure 4 , the heat dissipation assembly further comprises a flow guide structure 60, which is arranged in the mounting cavity 131 and located between the fan structure 40 and the air inlet 133. The flow guide structure 60 has a flow guide channel 61, and the air inlet end of the fan structure 40 communicates with the air inlet 133 through the flow guide channel 61. The flow guide channel 61 guides the flow direction of the air flow through the limit stop between the inner wall thereof and the air flow. In this way, the arrangement of the flow guide structure 60 can further increase the flow rate of the air flow and ensure the fixed flow direction of the air flow, thereby further reducing the possibility of turbulence or backflow during the flow of the air flow, improving the air intake efficiency of the fan structure 40, and further improving the operation reliability of the fan structure.

[0079] As shown in Figure 3 and Figure 4 , the flow guide structure 60 comprises a plurality of plate-shaped flow guide pieces 62, which are arranged at intervals along a predetermined direction. The plate faces of adjacent two plate-shaped flow guide pieces 62 surround the flow guide channel 61. The plate-shaped flow guide pieces 62 are rotatably arranged to adjust the extension direction and / or size of the flow guide channel 61 during the rotation of the plate-shaped flow guide pieces 62. In this way, the above arrangement of the plate-shaped flow guide pieces 62 can adaptively adjust the operation of the fan structure 40, that is, when the air intake is normal, the smaller air pressure inside the mounting cavity causes the plate-shaped flow guide pieces 62 to automatically rotate to an angle matching the flow direction of the air flow, so as to ensure the smoothness of the air intake. In the case of backflow, the backflow air flow blows the plate-shaped flow guide pieces 62 to rotate and close the flow guide channel 61, thereby closing the air inlet 133 to prevent the occurrence of backflow, and thereby avoiding the entry of air flow with high temperature into the server, so as to ensure the reliable and stable operation of the server.

[0080] In the embodiment, the plate-shaped flow guide 62 is vertically arranged, and rotating connection protrusions are arranged on two sides in the height direction of the plate-shaped flow guide 62. A second mounting plate 138 is arranged in the second sub-housing 136, and the second mounting plate 138 is horizontally arranged. The second mounting plate 138 and the surrounding plate are provided with two rotating mounting recesses, respectively. The two rotating mounting protrusions are respectively inserted into the two rotating mounting recesses and are clearance fitted, so that the plate-shaped flow guide 62 can freely rotate under the action of a slight airflow, thereby ensuring that the plate-shaped flow guide 62 can block the backflow airflow.

[0081] In the embodiment, the two air inlets 133 are respectively located on the two sides of the second mounting plate 138, that is, the second mounting plate 138 can also play a role in separating the airflow. In cooperation with the structure of the fan structure 40, the mounting cavity 131 at the air inlet 133 can be divided into two independent air inlet cavities, further avoiding the problem of turbulence between the airflows.

[0082] Optionally, the second mounting plate 138 is inserted between the two fan structures 40 to further improve the sealing performance of the air inlet cavity.

[0083] In the embodiment, the upper plate surface and the lower plate surface of the second mounting plate 138 are both provided with rotating mounting recesses, and the rotating mounting recesses are multiple. A plurality of plate-shaped flow guides 62 are respectively arranged at the two air inlets 133, thereby realizing independent on-off control of the two air inlets 133.

[0084] As shown in Figure 1 and Figure 3 , the bottom of the housing 10 is provided with an avoiding opening. The avoiding opening is used for inserting the positioning structure 320 of the heat dissipation module into the positioning hole of the fan structure 40 during the installation of the heat dissipation assembly, so as to position the installation position of the heat dissipation assembly. And / or, the avoiding opening is used for avoiding the electrical connection end 310 of the heat dissipation module during the installation of the heat dissipation assembly. In this way, the above-mentioned arrangement can further facilitate the installation of the heat dissipation device 100 by the worker, that is, by avoiding the positioning structure 320 and the electrical connection end 310 through the avoiding opening during the installation of the heat dissipation device 100, the positioning structure 320 and the electrical connection end 310 can be quickly inserted into the mounting cavity 131, thereby further reducing the maintenance difficulty of the worker and improving the maintenance efficiency of the worker.

[0085] In the embodiment, through the above-mentioned limitation of the first sub-housing 135 and the second sub-housing 136, it can be obtained that the bottom of the housing main body 13 in the embodiment is an open design, that is, the avoiding opening is formed through the bottom opening of the housing main body 13.

[0086] In the embodiment, the fan structure 40 includes a plug-in part 41, and the plug-in part is used to realize electrical connection.

[0087] It can be seen that the heat dissipation device 100 in the embodiment has the advantages of simple structure design, low cost, and tool-free maintenance operation.

[0088] The embodiment also provides a heat dissipation module, as shown in the drawings. Figures 5 to 11 The heat dissipation module includes a shell 200 and the heat dissipation device 100. The shell 200 includes a shell body 210 and a mounting frame 220. The shell body 210 has a setting cavity 211. The mounting frame 220 is detachably arranged in the setting cavity 211 through a clamping assembly 230. The mounting frame 220 has a matching part 221. The clamping structure 20 of the heat dissipation device 100 is clamped and matched with the matching part 221 to be fixed in the mounting frame 220. The heat dissipation device 100 is the heat dissipation device 100 described above. In this way, the mounting frame 220 is designed to be detachable through the clamping assembly 230, so that it can be quickly disassembled to replace the mounting frame 220 of different specifications and sizes to install the heat dissipation device 100 of different specifications and sizes, further match the servers with different heat dissipation requirements, and thus improve the versatility of the heat dissipation module.

[0089] As shown in the drawings, Figures 5 to 11 The heat dissipation device 100 is at least two. The mounting frame 220 includes side plates 222 and a partition 223. The side plates 222 are at least two. The at least two side plates 222 are oppositely arranged to form a cavity 224 for accommodating the heat dissipation device 100. The partition 223 is arranged between the at least two oppositely arranged side plates 222 to divide the cavity 224 into at least two sub-cavities 2241. The side plates 222 and the partition 223 are provided with the matching part 221. The at least two sub-cavities 2241 and the at least two heat dissipation devices 100 are arranged one-to-one. In this way, the above arrangement enables the mounting frame 220 to simultaneously install multiple heat dissipation devices 100, and enables the workers to simultaneously disassemble the multiple heat dissipation devices 100 by directly disassembling the mounting frame 220, thereby further reducing the maintenance difficulty of the workers and improving the maintenance efficiency of the workers.

[0090] In the embodiment, the side plates 222 are two. The two side plates 222 are oppositely arranged. The partition 223 is also in the form of a plate and is arranged between the two side plates 222 to divide the cavity 224 into two sub-cavities 2241, so that the mounting frame 220 can install two heat dissipation devices 100.

[0091] As shown in the drawings, Figures 5 to 11As shown, the housing 200 further comprises a mounting column 240 arranged in the setting cavity 211, and a clamping assembly 230 is arranged between the mounting frame 220 and the cavity wall of the setting cavity 211, and between the mounting frame 220 and the mounting column 240. In this way, the mounting column 240 not only plays a clamping mounting support and improves the clamping fixing stability of the mounting frame 220, but also avoids that the setting size of the mounting frame 220 is too large, so as to avoid that the mounting frame 220 is bent or even damaged in the process of disassembling the mounting frame 220 to synchronously disassemble the plurality of heat dissipation devices 100 on the mounting frame 220, thereby effectively prolonging the service life of the mounting frame 220.

[0092] In the embodiment, the mounting column 240 is arranged on the bottom wall of the setting cavity 211 and located at the middle part of the setting cavity 211 (in the width direction of the setting cavity 211), and two mounting frames 220 are arranged on both sides of the mounting column 240 in the width direction of the setting cavity 211, that is, four heat dissipation devices 100 and eight fan structures 40 are arranged in the heat dissipation module in the embodiment.

[0093] In the embodiment, the housing body 210 is provided with a fixing frame 260, and the fixing frame 260 forms part of the cavity wall of the setting cavity 211.

[0094] In the embodiment, the clamping assembly 230 comprises a first clamping piece 231, a second clamping piece 232, a third clamping piece 233 and a fourth clamping piece 234. The first clamping piece 231 is a buckle piece (such as a hole or a recess) arranged on the fixing frame 260, the second clamping piece 232 is a clamping hook piece arranged on the side plate 222, the clamping of the mounting frame 220 and the fixing frame 260 is realized through the clamping cooperation between the first clamping piece 231 and the second clamping piece 232, the third clamping piece 233 is a buckle piece (such as a hole or a recess) arranged on the side surface of the mounting column 240, and the fourth clamping piece 234 is a clamping hook piece arranged on the side plate 222, and the clamping of the mounting frame 220 and the mounting column 240 is realized through the clamping cooperation between the third clamping piece 233 and the fourth clamping piece 234.

[0095] It should be noted that the structures between the first clamping piece 231 and the second clamping piece 232 and the structures between the third clamping piece 233 and the fourth clamping piece 234 can be replaced with each other to adapt to different use requirements, thereby improving the processing flexibility of the workers.

[0096] As Figure 10As shown, the heat dissipation module further comprises a power supply module 300, which is arranged in the arrangement cavity 211 and below the mounting frame 220. The mounting frame 220 further comprises a bottom plate 225, and the bottom plate 225 is provided with a relief hole 2251 for avoiding the electrical connection end 310 and / or the positioning structure 320 of the power supply module 300. In this way, the above arrangement further ensures that the arrangement position of the power supply module 300 can match the arrangement position of the mounting frame 220, so as to ensure that the worker can realize the accurate installation and electrical connection operation of the heat dissipation device 100 through the simple operation of inserting or placing, further reducing the maintenance difficulty of the worker and improving the maintenance efficiency.

[0097] In the embodiment, the relief hole 2251 comprises a first hole part 2251a and a second hole part 2251b. The first hole part 2251a is arranged at a position matching the arrangement position of the electrical connection end 310 to avoid the electrical connection end 310. The second hole part 2251b is arranged at a position matching the positioning structure 320 to avoid the positioning structure 320.

[0098] In the embodiment, the positioning structure 320 is arranged in a columnar shape.

[0099] In the embodiment, the electrical connection end 310 is in the form of a plug.

[0100] It should be noted that the position of the electrical connection end 310 in the embodiment is opposite to the partition 223, and therefore the partition 223 is provided with a relief gap in communication with the first hole part 2251a.

[0101] It should be noted that if the arrangement distance between the positioning structure 320 and the electrical connection end 310 is close, only one relief hole 2251 can be arranged to simultaneously avoid the two.

[0102] As shown in the figure, Figures 7 to 9 The shell 200 further comprises a cover plate 250 covering the shell main body 210 to protect the structure in the arrangement cavity 211.

At the same time, the cover plate 250 is provided with a locking structure of a locking piece 420 of the locking assembly 400, and the top surface of the mounting column 240 is also provided with a locking matching structure of the locking piece 420.

When the cover plate 250 is closed, the elastic button member is pressed down, the intrusion switch circuit is powered off and not working, and the intrusion alarm prompt is not performed.

[0107] The embodiment further provides a server comprising the heat dissipation module.

[0108] It should be noted that the plurality of in the above embodiment means at least two.
