Description

Technical Field

[0001] The present invention relates to the technical field of server heat dissipation, and in particular to a fan heat dissipation device. Background Art

[0002] In recent years, with the continuous growth of server performance requirements, the power consumption of graphics processing units (GPUs) and central processing units (CPUs) has also continued to increase, bringing increasingly severe heat dissipation challenges to server architecture design engineers. In the heat dissipation system of air-cooled servers, the performance of the fan and the air volume have become the key factors in determining the heat dissipation effect. At present, server fans are mainly divided into 4056, 6056, 8086 and other series. These series are mainly divided according to their cross-sectional dimensions, including 40*40mm, 60*60mm, and 80*80mm. The heat dissipation performance increases with the increase of size; among them, fans with a cross-sectional dimension of 80*80mm are gradually becoming the mainstream of server fan selection due to their excellent heat dissipation performance.

[0003] In the current server settings, in order to facilitate the operator's plugging and unplugging operations, the fan plate is usually placed directly below the fan to achieve direct plug-in connection with the fan terminal. However, in a 4U server with a chassis height of 174.8mm, if two layers of fans with a cross-sectional size of 80*80mm are used for efficient heat dissipation, the minimum installation height has reached 161mm. On this basis, the installation requirements of fan terminals, fan plates and related components must also be considered. These components not only have a certain volume, but also require a certain gap to be reserved in the design to ensure good heat dissipation and electrical connection stability. Under such height restrictions, operators not only have to face the physical challenges of a small space, but also need to ensure that all components can be accurately aligned while meeting heat dissipation efficiency and electrical safety standards. This small space installation environment greatly increases the difficulty of installation. Summary of the invention

[0004] In view of this, the present invention provides a fan heat dissipation device to solve the problem that it is difficult to install two layers of fans with larger cross-sectional dimensions in a 4U server.

[0005] The present invention provides a fan heat dissipation device, comprising a mounting frame, a fan plate and a fan mechanism; the mounting frame is provided with a first opening on one side along a first direction, and a second opening on one side along a second direction; the fan plate is arranged in the mounting frame and is located at the second opening; the fan mechanism is arranged in the mounting frame through the first opening; the fan mechanism comprises a fan module and a fan frame; the fan module is arranged in the fan frame and is arranged with the fan plate along the second direction; a connecting terminal is protruded on one side of the fan frame close to the fan plate, the connecting terminal is electrically connected to the fan module, and is plugged with the fan plate along the first direction; the first direction is the height direction of the mounting frame, and the second direction is perpendicular to the first direction.

[0006] Since the fan module and the fan plate are arranged along the second direction, and the fan mechanism is plugged in and out of the fan plate through the connecting terminals protruding from the fan frame, the fan mechanism is not restricted by the spatial layout of the fan plate and the connecting terminals, and can be smoothly plugged in and installed in the first direction. Even in a compact and specific chassis space, the fan mechanism can be hot-swapped and arranged smoothly, thereby optimizing space utilization and ensuring functional independence and interoperability between the fan mechanism and structures such as the fan plate.

[0007] In an optional implementation, a connecting portion is protruded from one side of the fan frame close to the fan plate, and the connecting terminal is connected to one side of the connecting portion close to the fan plate.

[0008] By setting the connecting part, a stable supporting point is provided for the connecting terminal, ensuring that the connecting terminal can be stably fixed in the required position, which not only realizes the effective installation of the connecting terminal, but also further enhances its stability, thereby ensuring the reliability of the connection between the entire fan mechanism and the fan plate.

[0009] In an optional implementation, the connecting portion and the fan plate are arranged in sequence along the first direction, and the fan plate is disposed on a side of the connecting portion away from the first opening.

[0010] By arranging the fan plate on the side of the connecting portion away from the first opening, when the fan mechanism is plugged in or out at the first opening, the fan plate can completely avoid interference with the plugging and unplugging path, which not only improves the smoothness and convenience of the plugging and unplugging operation, allowing the fan mechanism to be installed or disassembled through the first opening without hindrance, but also effectively protects the integrity and safety of the fan mechanism and its surrounding structures, providing convenience for subsequent maintenance or replacement operations.

[0011] In an optional embodiment, the mounting frame includes a partition plate, which is disposed between the fan plate and the connecting portion. A through hole is provided on the partition plate, and the connecting terminal passes through the through hole to be plugged into the fan plate.

[0012] By setting up a partition plate, effective isolation is achieved between the fan plate and the fan mechanism, ensuring that the fan plate can remain stable when the fan mechanism is plugged in and out, avoiding unnecessary linked pull-out, and preventing possible misoperation or interference to the fan plate when plugging and unplugging the fan mechanism. The independence of the fan plate and the fan mechanism during the plug-in and pull-out process is ensured, avoiding the risk of system instability or hardware damage caused by misplugging the fan plate, thereby greatly improving the accuracy and safety of the operation.

[0013] In an optional embodiment, a third opening is provided on a side of the connection portion facing away from the fan module, the third opening is provided on a side close to the connection terminal, and the fan frame further includes a front cover plate detachably connected to the third opening.

[0014] By arranging a third opening on the side of the connecting part away from the fan module, and the third opening is arranged on the side close to the connecting terminal, it is convenient for the operator to perform operations such as installation and removal of the connecting terminal through the third opening; and by arranging a front cover plate detachably connected to the third opening, not only the openness of the connecting part is maintained during operations such as installation and removal of the connecting terminal, but also it is ensured that when no operation is performed, the front cover plate can close the third opening to block the invasion of external debris and potential risks, thereby protecting other components inside the fan mechanism.

[0015] In an optional embodiment, the fan module includes one or more fan units, the multiple fan units are arranged in sequence along a first direction, each fan unit is connected to a corresponding connection terminal, and the multiple connection terminals are arranged in sequence along a third direction; the first direction, the second direction and the third direction are perpendicular to each other.

[0016] Since the fan module may include multiple fan units, and the fan module is arranged in the fan frame, the connection with the fan board is achieved through the connection part of the fan frame, so that the hot-swap operation of multiple fan units can be completed at one time, which greatly saves the operation time and improves the efficiency of installation and maintenance; and since the multiple fan units are arranged in sequence along the first direction, the space of the fan module in the second direction and the third direction is saved, and the space utilization rate inside the chassis is improved; and since the multiple connecting terminals are arranged in sequence along the third direction, mutual interference between the multiple connecting terminals during installation is avoided, and wiring is convenient; since each fan unit is connected to a corresponding connecting terminal, when a fan unit fails and needs maintenance, it can be handled separately without affecting the normal operation of other fan units, thereby realizing timely maintenance of the faulty fan unit without interrupting the overall operation of the system, thereby ensuring the continuous and efficient heat dissipation performance of the fan module, and further improving the stability and reliability of the system.

[0017] In an optional implementation, the fan unit is connected to the connection terminal via a cable, a cable management clip is provided on the connection portion, and the cable is fixed on the cable management clip.

[0018] When the fan module is running, the cold air generated will cause the cables to swing uncontrollably, which not only affects the aesthetics of the cable layout, but also increases the risk of the cables being accidentally stuck inside the fan unit and damaged, affecting the stability and safety of the system. Therefore, by setting a cable management clip, the cables can be firmly fixed, and the best constraint on the cables can be achieved with minimal intervention, which not only ensures the freedom of the cables to meet the necessary flexibility requirements, but also avoids the potential risks caused by excessive swinging, effectively prevents the cables from being damaged by the fan blades due to swinging, and optimizes the cable layout, improving the overall aesthetics and maintenance convenience of the system.

[0019] In an optional embodiment, the fan mechanism also includes a light guide column, a top plate is provided on the side of the fan frame close to the first opening, a light guide hole is provided on the top plate, and a fan logo is provided on one side of the light guide hole; the fan unit, the light guide column, the light guide hole and the fan logo are all arranged in a one-to-one correspondence.

[0020] By arranging the fan units, light guide columns, light guide holes and fan identifications in a one-to-one correspondence, it is convenient for operators to quickly and accurately observe the operating status of each fan unit intuitively.

[0021] In an optional embodiment, a plurality of first mounting grooves are provided in the mounting frame along a third direction, and each first mounting groove is connected to a first opening, and a group of fan mechanisms are correspondingly installed in each first mounting groove; a second mounting groove is provided in the mounting frame, the second mounting groove is connected to the second opening, the fan plate is arranged in the second mounting groove and extends along the third direction; and a plurality of groups of fan mechanisms are plugged into the fan plate.

[0022] By arranging a plurality of first mounting grooves along a third direction in the mounting frame, the simultaneous independent installation of a plurality of fan mechanisms is achieved, so that each fan mechanism can independently perform its heat dissipation function and ensure that they do not interfere with each other, thereby effectively avoiding performance degradation caused by mutual collision or airflow turbulence; and each fan mechanism can be precisely installed in a predetermined position, which not only simplifies the installation process, but also improves the reliability and consistency of the installation.

[0023] In an optional embodiment, a force-bearing member is provided on the mounting frame, and the fan mechanism also includes a fan handle, which is located on the side where the first opening is located and is rotatably connected to the fan frame. The fan handle has a first locking position and a second locking position that are locked with different force points of the force-bearing member. When the fan handle is in the first locking position, the fan handle rotates to assist the connection between the fan mechanism and the mounting frame; when the fan handle is in the second locking position, the fan handle rotates to assist the separation of the fan mechanism and the mounting frame.

[0024] By arranging the fan handle in cooperation with the force-bearing part, the force required to be applied during the plugging and unplugging process of the fan mechanism can be significantly reduced according to the principle of leverage, so that the operator only needs to input a small amount of force to generate sufficient torque to overcome the resistance when the fan mechanism is plugged and unplugged. This not only reduces the force required to be applied by the operator, but also makes the plugging and unplugging action smoother and smoother, avoiding mechanical damage or safety hazards caused by excessive or uneven force, and significantly improves the efficiency and convenience of the operation, so that the operator can complete the plugging and unplugging of the fan mechanism in a shorter time.

[0025] In an optional embodiment, the fan handle includes a first handle and a second handle; the first handle includes a first assisting member and a first connecting plate, the first assisting member includes a first force-bearing end and a first assisting end which are sequentially arranged, and the first force-bearing end is rotatably connected to one side of the fan frame along the second direction; the first connecting plate is arranged on a side close to the first opening and is connected to the first assisting end; the second handle includes a second assisting member and a second connecting plate, the second assisting member includes a second force-bearing end and a second assisting end which are sequentially arranged, and the second force-bearing end is rotatably connected to the other side of the fan frame along the second direction; the second connecting plate is arranged on a side close to the second opening one side of the fan frame and is connected to the second assisting end; two force-bearing members are respectively arranged on both sides of the mounting frame along the second direction, and the first force-bearing end and the second force-bearing end are respectively arranged corresponding to the two force-bearing members; the second connecting plate extends along the second direction and is detachably connected to the first connecting plate to form an operating member; a clearance groove and a top plate are arranged adjacent to the top plate along the third direction on the side of the fan frame close to the first opening, and the clearance groove and the top plate are arranged adjacent to each other along the third direction; when the fan handle is in the first locking position, the operating member is located in the clearance groove and is arranged parallel to the top plate of the fan frame; when the fan handle is in the second locking position, the operating member and the top plate of the fan frame are arranged adjacent to each other along the first direction.

[0026] By arranging the first handle and the second handle on both sides of the fan frame respectively along the second direction, and connecting the first handle and the second handle to each other, not only the overall structural strength of the fan handle is greatly enhanced, thereby ensuring its high reliability performance, but also the convenience and efficiency of the fan handle during the assembly process are significantly improved; since a clearance groove and a top plate are provided on the side of the fan frame close to the first opening, the clearance groove and the top plate are adjacently arranged along the third direction, providing a safe avoidance space for the operating part of the fan handle; when the fan handle is in a non-use state, that is, in the first locking position, the operating part is located in the clearance groove and is arranged parallel to the top plate of the fan frame, which not only effectively avoids the fan handle from occupying additional space when not in use, but also ensures the integrity and aesthetics of the appearance of the fan mechanism, and avoids collision or interference problems that may be caused by the protrusion of the fan handle.

[0027] In an optional embodiment, the fan mechanism further includes a wind direction indicator, a top plate is provided on a side of the fan frame close to the first opening, and the wind direction indicator is arranged on the top plate.

[0028] By setting a wind direction mark on the top plate of the fan frame near the first opening, the operator can intuitively observe the wind direction flow of the fan mechanism at the first opening, which helps the operator to quickly confirm whether the fan mechanism is operating as expected and ensure the stability and safety of the overall system.

[0039] Combine the following Figures 1 to 6 , describing an embodiment of the present invention.

[0040] According to an embodiment of the present invention, a fan heat dissipation device is provided, including a mounting frame 1, a fan plate 2 and a fan mechanism 3; the mounting frame 1 is provided with a first opening on one side along the first direction, and a second opening on one side along the second direction; the fan plate 2 is arranged in the mounting frame 1 and is located at the second opening; the fan mechanism 3 is arranged in the mounting frame 1 through the first opening; the fan mechanism 3 includes a fan module 31 and a fan frame 32; the fan module 31 is arranged in the fan frame 32 and is arranged with the fan plate 2 along the second direction; a connecting terminal 33 is protruded from one side of the fan frame 32 close to the fan plate 2, the connecting terminal 33 is electrically connected to the fan module 31, and is plugged with the fan plate 2 along the first direction; the first direction is the height direction of the mounting frame 1, and the second direction is perpendicular to the first direction.

[0041] Since the fan module 31 and the fan plate 2 are arranged along the second direction, and the fan mechanism 3 is plugged in and out of the fan plate 2 through the connecting terminals 33 protruding from the fan frame 32, the fan mechanism 3 is not restricted by the spatial layout of the fan plate 2 and the connecting terminals 33, and can be smoothly plugged in and installed in the first direction. Even in a compact and specific chassis space, the fan mechanism 3 can be hot-swapped and arranged smoothly, thereby optimizing space utilization and ensuring functional independence and interoperability between structures such as the fan mechanism 3 and the fan plate 2.

[0042] In a specific implementation, the fan plate 2 is first arranged in the mounting frame 1 through the second opening along the second direction, and is detachably connected to the mounting frame 1 through fasteners such as screws; then the fan mechanism 3 is arranged in the mounting frame 1 through the first opening along the first direction, and is plugged into the connector on the fan plate 2 through the connecting terminal 33.

[0043] In one embodiment, a connecting portion 321 is protruded from one side of the fan frame 32 close to the fan plate 2 , and the connecting terminal 33 is connected to one side of the connecting portion 321 close to the fan plate 2 .

[0044] By providing the connecting portion 321, a stable supporting point is provided for the connecting terminal 33, ensuring that the connecting terminal 33 can be stably fixed at the desired position, which not only realizes the effective installation of the connecting terminal 33, but also further enhances its stability, thereby ensuring the reliability of the connection between the entire fan mechanism 3 and the fan plate 2.

[0045] In a specific implementation, a mounting groove is provided on the side wall of the connecting portion 321 close to the fan plate 2 , and the connecting terminal 33 is snapped into the mounting groove.

[0046] In a specific implementation, the sum of the heights of the connecting portion 321 and the fan plate 2 is equal to the height of the fan module 31 .

[0047] In one embodiment, the connection portion 321 and the fan plate 2 are sequentially arranged along the first direction, and the fan plate 2 is disposed on a side of the connection portion 321 away from the first opening.

[0048] By arranging the fan plate 2 on the side of the connection portion 321 away from the first opening, when the fan mechanism 3 is plugged in or out at the first opening, the fan plate 2 can completely avoid interference with the plugging and unplugging path, which not only improves the smoothness and convenience of the plugging and unplugging operation, so that the fan mechanism 3 can be installed or disassembled through the first opening without hindrance, but also effectively protects the integrity and safety of the fan mechanism 3 and its surrounding structures, providing convenience for subsequent maintenance or replacement operations.

[0049] In one embodiment, the mounting frame 1 includes a partition plate 11 , which is disposed between the fan plate 2 and the connecting portion 321 . A through hole 111 is disposed on the partition plate 11 , and the connecting terminal 33 passes through the through hole 111 to be plugged into the fan plate 2 .

[0050] By setting the partition plate 11, effective isolation is achieved between the fan plate 2 and the fan mechanism 3, ensuring that the fan plate 2 can remain stable when the fan mechanism 3 is plugged in and out, avoiding unnecessary linked unplugging, and preventing possible misoperation or interference to the fan plate 2 when plugging and unplugging the fan mechanism 3. The independence of the fan plate 2 and the fan mechanism 3 during the plugging and unplugging process is ensured, avoiding the risk of system instability or hardware damage caused by misplugging the fan plate 2, thereby greatly improving the accuracy and safety of the operation.

[0051] In one embodiment, a third opening is provided on a side of the connection portion 321 away from the fan module 31 , and the third opening is provided on a side close to the connection terminal 33 , and the fan frame 32 further includes a front cover plate 322 detachably connected to the third opening.

[0052] By providing a third opening on the side of the connecting portion 321 away from the fan module 31, and the third opening is provided on the side close to the connecting terminal 33, it is convenient for the operator to perform operations such as installation and removal of the connecting terminal 33 through the third opening; and by providing a front cover 322 detachably connected to the third opening, not only the openness of the connecting portion 321 during operations such as installation and removal of the connecting terminal 33 is maintained, but also it is ensured that when no operation is performed, the front cover 322 can close the third opening to block the invasion of external debris and potential risks, thereby protecting other components inside the fan mechanism 3.

[0053] In a specific implementation, the fan frame 32 further includes a mounting frame 325 , the connecting portion 321 is protrudingly disposed on the mounting frame 325 , and the front cover plate 322 is detachably connected to the mounting frame 325 .

[0054] Specifically, a first buckle is provided on the front cover plate 322 , and a slot is provided on the mounting frame 325 . The front cover plate 322 is engaged with the slot on the mounting frame 325 via the first buckle, thereby achieving tool-free installation between the front cover plate 322 and the mounting frame 325 .

[0055] In a specific embodiment, the fan frame 32 further includes a rear cover plate 326 , the fan module 31 is disposed in the mounting frame 325 , and the mounting frame 325 and the rear cover plate 326 are detachably connected to two sides of the fan module 31 along the second direction, respectively.

[0056] Specifically, a second buckle is provided on the rear cover plate 326, and a mounting hole is provided on the fan module 31. The rear cover plate 326 is snap-fitted with the mounting hole on the fan module 31 through the second buckle, thereby realizing tool-free installation between the rear cover plate 326 and the fan module 31.

[0057] In a specific embodiment, a top plate 324 and a bottom plate 327 are respectively provided on both sides of the mounting frame 325 along the first direction, the fan module 31 is located between the top plate 324 and the bottom plate 327 , and the rear cover plate 326 is snap-connected to both the top plate 324 and the bottom plate 327 .

[0058] In a specific embodiment, the fan module 31 is provided with two fan units 311. During assembly, the connection terminal 33 corresponding to the upper fan unit 311 is first snapped into the corresponding installation groove, and then the connection terminal 33 corresponding to the lower fan unit 311 is snapped into the corresponding installation groove. After the connection terminal 33 is snapped into place, the fan unit 311 is installed; after the fan unit 311 and the connection terminal 33 are installed in place, the cables are fixed by the cable management clip 323, and after the fixing is completed, the front cover 322 is installed.

[0059] In one embodiment, the fan module 31 includes one or more fan units 311, and the multiple fan units 311 are arranged in sequence along the first direction. Each fan unit 311 is connected to a corresponding connection terminal 33, and the multiple connection terminals 33 are arranged in sequence along the third direction; the first direction, the second direction and the third direction are perpendicular to each other.

[0060] Since the fan module 31 may include multiple fan units 311, and the fan module 31 is arranged in the fan frame 32, the fan frame 32 is connected to the fan board 2 through the connection part 321, so that the hot-swap operation of multiple fan units 311 can be completed at one time, which greatly saves the operation time and improves the efficiency of installation and maintenance; and since the multiple fan units 311 are arranged in sequence along the first direction, the space of the fan module 31 in the second direction and the third direction is saved, and the space utilization rate inside the chassis is improved; and since the multiple connection terminals 33 are arranged in sequence along the third direction, mutual interference between the multiple connection terminals 33 during installation is avoided, which facilitates wiring; since each fan unit 311 is connected to a corresponding connection terminal 33, when a fan unit 311 fails and needs maintenance, it can be handled separately without affecting the normal operation of other fan units 311, so that the faulty fan unit 311 can be repaired in time without interrupting the overall operation of the system, thereby ensuring the continuous and efficient heat dissipation performance of the fan module 31 and further improving the stability and reliability of the system.

[0061] In a specific implementation, the fan module 31 includes two layers of fan units 311 with a cross-sectional size of 80*80mm. Since the traditional 4U server adopts the design concept of two layers of fan units 311 with a cross-sectional size of 60*60mm, when the high-power graphics processor is running, the speed of the fan unit 311 with a cross-sectional size of 60*60mm needs to be increased to the maximum speed. At this time, the fan unit 311 is very noisy, causing severe noise pollution to the operating environment of the operator; and since the heat dissipation performance of the fan unit 311 with a cross-sectional size of 60*60mm is still not enough to fully cope with the heat dissipation requirements of the high-power graphics processor, the power consumption of the graphics processor has to be limited, thereby limiting the overall performance of the server. If two layers of fan units 311 with a cross-sectional size of 80*80mm are used for heat dissipation, the minimum installation height reaches 161mm. By arranging the fan plate 2 and the connecting terminal 33 adjacent to the fan module 31 along the second direction, the entire fan heat dissipation device can be properly arranged in a 4U server with a height of 174.8mm.

[0062] In one embodiment, the fan unit 311 is connected to the connection terminal 33 via a cable, a cable management clip 323 is provided on the connection portion 321 , and the cable is fixed on the cable management clip 323 .

[0063] When the fan module 31 is running, the cold air generated will cause the cables to swing uncontrollably, which not only affects the aesthetics of the cable layout, but also increases the risk of the cables being accidentally stuck inside the fan unit 311 and damaged, affecting the stability and safety of the system; therefore, by providing a cable management clip 323, the cables can be firmly fixed, and the best constraint on the cables can be achieved with minimal intervention, which not only ensures the freedom of the cables to meet the necessary flexibility requirements, but also avoids the potential risks caused by excessive swinging, effectively prevents the cables from being damaged by the fan blades due to swinging, and optimizes the cable layout, thereby improving the overall aesthetics and maintenance convenience of the system.

[0064] In a specific implementation, the fan module 31 is provided with two fan units 311 , and two cable management clips 323 are provided. The two cable management clips 323 are respectively arranged corresponding to the two fan units 311 , and the two cable management clips 323 are respectively arranged on the inner walls on both sides of the connecting portion 321 along the third direction.

[0065] In one embodiment, the fan mechanism 3 also includes a light guide column, a top plate 324 is provided on the side of the fan frame 32 close to the first opening, a light guide hole 34 is provided on the top plate 324, and a fan logo 35 is provided on one side of the light guide hole 34; the fan unit 311, the light guide column, the light guide hole 34 and the fan logo 35 are all arranged in a one-to-one correspondence.

[0066] By arranging the fan units 311 , the light guide columns, the light guide holes 34 and the fan identifiers 35 in a one-to-one correspondence, it is convenient for operators to quickly and accurately observe the operating status of each fan unit 311 intuitively.

[0067] In a specific embodiment, each fan unit 311 is equipped with a corresponding light guide column, which is connected to light-emitting elements such as status indicator lights inside the fan unit 311. When the fan unit 311 is in operation, the light emitted by the light-emitting elements will be transmitted along the light guide column and projected to the outside through the light guide hole 34.

[0068] Specifically, the brightness, color or flashing mode of the light of the light emitting element can be dynamically adjusted according to the operating status of the fan unit 311, thereby providing intuitive and real-time status feedback to the operator.

[0069] In a specific implementation, a plurality of light guide holes 34 are spaced apart from each other, and the light guide holes 34 are rectangular holes or circular holes. Specifically, the shape, size, distribution and other parameters of the light guide holes 34 can be set according to actual conditions to ensure that light loss can be reduced and the clarity and accuracy of visual feedback can be improved.

[0070] In a specific implementation manner, the fan identification 35 may adopt elements such as specific colors, patterns or texts, which can intuitively reflect each corresponding fan unit 311 .

[0071] In one embodiment, a plurality of first mounting grooves 12 are provided in the mounting frame 1 along the third direction, and each first mounting groove 12 is connected to a first opening, and a group of fan mechanisms 3 are correspondingly installed in each first mounting groove 12; a second mounting groove 13 is provided in the mounting frame 1, and the second mounting groove 13 is connected to the second opening, and the fan plate 2 is arranged in the second mounting groove 13 and extends along the third direction; and a plurality of groups of fan mechanisms 3 are plugged into the fan plate 2.
