Description

Technical Field

[0001] This invention relates to the field of server heat dissipation technology, and more specifically to fan cooling devices. Background Technology

[0002] In recent years, with the continuous growth in server performance demands, the power consumption of graphics processing units (GPUs) and central processing units (CPUs) has also been increasing, posing increasingly severe heat dissipation challenges for server architecture engineers. In the heat dissipation system of air-cooled servers, fan performance and airflow have become key factors determining the heat dissipation effect. Currently, server fans are mainly divided into series such as 4056, 6056, and 8086. These series are mainly classified according to their cross-sectional dimensions, specifically including three types: 40*40mm, 60*60mm, and 80*80mm. The heat dissipation performance increases sequentially with the size. Among them, fans with a cross-sectional dimension of 80*80mm are gradually becoming the mainstream choice for server fans due to their excellent heat dissipation performance.

[0003] In current server setups, fan plates are typically placed directly below the fans for easy plug-and-play connections. However, in a 4U server with a chassis height of 174.8mm, using two 80*80mm fans for efficient cooling already results in a minimum installation height of 161mm. Furthermore, the installation requirements for fan terminals, fan plates, and related components must be considered. These components not only have a certain size but also require specific clearances to ensure good heat dissipation and electrical connection stability. Under these height constraints, operators not only face the physical challenge of limited space but also need to ensure precise alignment of all components while meeting both cooling efficiency and electrical safety standards. This confined installation environment significantly increases the installation difficulty. Summary of the Invention

[0004] In view of this, the present invention provides a fan cooling device to solve the problem of difficulty in installing two fans with large cross-sectional dimensions in a 4U server.

[0005] This invention provides a fan cooling device, including a mounting frame, a fan plate, and a fan mechanism; the mounting frame has 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 disposed within the mounting frame and located at the second opening; the fan mechanism passes through the first opening and is disposed within the mounting frame; the fan mechanism includes a fan module and a fan frame; the fan module is disposed within the fan frame and arranged with the fan plate along the second direction; a connecting terminal protrudes from the side of the fan frame near the fan plate, the connecting terminal being electrically connected to the fan module and inserted into 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] Because the fan module and fan plate are arranged along the second direction, and the fan mechanism is plugged into and unplugged from the fan plate through the protruding connection terminals on the fan frame, the fan mechanism is not constrained by the spatial layout of the fan plate and connection terminals, and can be smoothly plugged into and unplugged in the first direction. Even in a compact and specific chassis space, the hot-swappable arrangement of the fan mechanism can be smoothly realized, optimizing space utilization, while ensuring the functional independence and interoperability between the fan mechanism and the fan plate and other structures.

[0007] In one alternative embodiment, a connecting portion protrudes from the side of the fan frame near the fan plate, and a connecting terminal is connected to the connecting portion near the side of the fan plate.

[0008] By setting up a connecting part, a stable support point is provided for the connecting terminal, ensuring that the connecting terminal can be stably fixed in the required position. This not only achieves 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 one alternative embodiment, the connecting portion and the fan plate are arranged sequentially along a first direction, and the fan plate is disposed on the side of the connecting portion opposite to the first opening.

[0010] By placing the fan plate on the side of the connecting part away from the first opening, when the fan mechanism is inserted or removed at the first opening, the fan plate can completely avoid interfering with the insertion or removal path. This not only improves the smoothness and convenience of the insertion and removal operation, allowing the fan mechanism to be installed or removed without obstruction through the first opening, but also effectively protects the integrity and safety of the fan mechanism and its surrounding structure, providing convenience for subsequent maintenance or replacement operations.

[0011] In one alternative embodiment, the mounting frame includes a partition plate disposed between the fan plate and the connecting portion, the partition plate having a through hole through which a connecting terminal passes and is inserted into the fan plate.

[0012] By setting up a separator plate, effective isolation is achieved between the fan board and the fan mechanism. This ensures that the fan board remains stable during the insertion and removal of the fan mechanism, avoiding unnecessary linkage during removal. It also prevents possible misoperation or interference to the fan board during the insertion and removal of the fan mechanism, ensuring the independence of the fan board and the fan mechanism during the insertion and removal process. This avoids the risk of system instability or hardware damage caused by accidental removal of the fan board, thereby significantly improving the accuracy and safety of the operation.

[0013] In one alternative embodiment, the connecting portion has a third opening on the side opposite to the fan module, the third opening being located near the connecting terminal, and the fan frame also includes a front cover plate detachably connected to the third opening.

[0014] By providing a third opening on the side of the connecting part away from the fan module, and by placing the third opening near the connecting terminal, it is convenient for operators to install and remove the connecting terminal through the third opening. Furthermore, by providing a front cover plate detachably connected to the third opening, not only is the connection part kept open during the installation and removal of the connecting terminal, but the front cover plate can also close the third opening when no operation is being performed, preventing the intrusion of external debris and potential risks, thus protecting other components inside the fan mechanism.

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

[0016] Because the fan module can include multiple fan units and is housed within the fan frame, it connects to the fan board via the fan frame's connector, enabling simultaneous hot-swapping of multiple fan units. This significantly saves operation time and improves installation and maintenance efficiency. Furthermore, the sequential arrangement of multiple fan units along the first direction saves space in the second and third directions, increasing the internal space utilization of the chassis. The sequential arrangement of multiple connection terminals along the third direction avoids interference during installation and facilitates cable routing. Since each fan unit has a corresponding connection terminal, a faulty fan unit can be repaired individually without affecting the normal operation of other fan units. This allows for timely repair of faulty fan units without interrupting the overall system operation, ensuring the fan module's continuous and efficient heat dissipation performance and further enhancing system stability and reliability.

[0017] In one alternative embodiment, the fan unit is connected to the connection terminal via a cable, and a cable clip is provided on the connection part to fix the cable to the cable clip.

[0018] When the fan module is running, the cold air it generates can cause the cables to swing uncontrollably. This not only affects the aesthetics of the cable layout but also increases the risk of cables getting accidentally caught inside the fan unit and being damaged, impacting the system's stability and safety. Therefore, by installing cable clips, the cables can be securely fixed, achieving optimal constraint on the cables with minimal intervention. This ensures the cables have the freedom to meet necessary flexibility requirements while avoiding potential risks caused by excessive swinging. It effectively prevents cables from being damaged by the fan blades due to swinging, optimizes the cable layout, and improves the overall aesthetics and ease of maintenance of the system.

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

[0020] By setting up a one-to-one correspondence between the fan unit, light guide column, light guide hole and fan label, operators can quickly and accurately observe the operating status of each fan unit.

[0021] In one optional embodiment, the mounting frame is provided with a plurality of first mounting slots along a third direction, and each first mounting slot is connected to a first opening. Each first mounting slot is provided with a corresponding set of fan mechanisms. The mounting frame is provided with a second mounting slot, which is connected to a second opening. The fan plate is disposed in the second mounting slot and extends along a third direction. The plurality of fan mechanisms are inserted into the fan plate.

[0022] By setting multiple first mounting slots along a third direction within the mounting frame, multiple fan mechanisms can be installed independently at the same time. This allows each fan mechanism to perform its heat dissipation function independently, while ensuring that they do not interfere with each other, effectively avoiding performance degradation caused by mutual collisions or airflow turbulence. Furthermore, 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 one optional embodiment, the mounting frame is provided with a force-bearing component, and the fan mechanism further includes a fan handle. The fan handle 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 different from the force-bearing component in terms of the force-bearing point. When the fan handle is in the first locking position, the rotation of the fan handle assists in the insertion of the fan mechanism into the mounting frame; when the fan handle is in the second locking position, the rotation of the fan handle assists in the separation of the fan mechanism from the mounting frame.

[0024] By setting the fan handle to work in conjunction with the force-bearing components, the force required for inserting and removing the fan mechanism can be significantly reduced based on the lever principle. This allows the operator to generate sufficient torque with only a small amount of force input to overcome the resistance during the insertion and removal of the fan mechanism. This not only reduces the force required by the operator but also makes the insertion and removal action smoother and more stable, avoiding mechanical damage or safety hazards caused by excessive or uneven force. Furthermore, it significantly improves the efficiency and convenience of operation, enabling the operator to complete the insertion and removal of the fan mechanism in a shorter time.

[0025] In one 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 including a first force-receiving end and a first assisting end arranged sequentially, the first force-receiving end being rotatably connected to one side of the fan frame along a second direction; the first connecting plate is disposed on the side near the first opening and connected to the first assisting end; the second handle includes a second assisting member and a second connecting plate, the second assisting member including a second force-receiving end and a second assisting end arranged sequentially, the second force-receiving end being rotatably connected to the other side of the fan frame along a second direction; the second connecting plate is disposed near the second opening. The first connecting plate extends along the second direction and is detachably connected to the first connecting plate to form an operating component. A clearance groove and a top plate are provided on the side of the fan frame near the first opening, with the clearance groove and top plate adjacent to each other along the third direction. When the fan handle is in the first locking position, the operating component is located in the clearance groove and is parallel to the top plate of the fan frame. When the fan handle is in the second locking position, the operating component is adjacent to the top plate of the fan frame along the first direction.

[0026] By setting the first handle and the second handle on both sides of the fan frame along the second direction and connecting them to each other, the overall structural strength of the fan handle is greatly enhanced, thus ensuring its high reliability performance. At the same time, the convenience and efficiency of the fan handle during assembly are also significantly improved. Since the side of the fan frame near the first opening is provided with a clearance groove and a top plate, and the clearance groove and the top plate are arranged adjacent to each other along the third direction, a safe clearance space is provided for the operating part of the fan handle. When the fan handle is in the 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. This not only effectively avoids the fan handle occupying extra space when not in use, but also ensures the integrity and aesthetics of the fan mechanism and avoids collision or interference problems that may be caused by the protruding fan handle.

[0027] In one alternative embodiment, the fan mechanism further includes a wind direction indicator, and a top plate is provided on the side of the fan frame near the first opening, with the wind direction indicator disposed on the top plate.

[0028] By setting a wind direction indicator on the top plate of the fan frame near the first opening, operators can visually observe the airflow of the fan mechanism at the first opening. This helps operators quickly confirm whether the fan mechanism is operating as expected, ensuring the stability and safety of the overall system. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.

[0040] According to an embodiment of the present invention, a fan cooling device is provided, including a mounting frame 1, a fan plate 2, and a fan mechanism 3; the mounting frame 1 has a first opening on one side along a first direction and a second opening on one side along a second direction; the fan plate 2 is disposed within the mounting frame 1 and located at the second opening; the fan mechanism 3 is disposed within 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 disposed within the fan frame 32 and arranged with the fan plate 2 along the second direction; a connecting terminal 33 protrudes from the side of the fan frame 32 near the fan plate 2, the connecting terminal 33 is electrically connected to the fan module 31 and is inserted into 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 into and unplugged from the fan plate 2 through the connecting terminal 33 protruding on the fan frame 32, the fan mechanism 3 is not constrained by the spatial layout of the fan plate 2 and the connecting terminal 33, and can be smoothly plugged into and unplugged in the first direction. Even in a compact and specific chassis space, the hot-swappable arrangement of the fan mechanism 3 can be smoothly realized, optimizing the space utilization, while ensuring the functional independence and interoperability between the fan mechanism 3 and the fan plate 2 and other structures.

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

[0043] In one embodiment, the fan frame 32 has a protruding connecting portion 321 on the side near the fan plate 2, and the connecting terminal 33 is connected to the connecting portion 321 on the side near the fan plate 2.

[0044] By providing the connecting part 321, a stable support point is provided for the connecting terminal 33, ensuring that the connecting terminal 33 can be stably fixed in the required position. This not only achieves 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 embodiment, the connecting part 321 has a mounting groove on the side wall near 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 part 321 and the fan plate 2 is equal to the height of the fan module 31.

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

[0048] By setting the fan plate 2 on the side of the connecting part 321 away from the first opening, when the fan mechanism 3 is inserted or removed at the first opening, the fan plate 2 can completely avoid interfering with the insertion or removal path. This not only improves the smoothness and convenience of the insertion and removal operation, allowing the fan mechanism 3 to be installed or removed without obstruction through the first opening, but also effectively protects the integrity and safety of the fan mechanism 3 and its surrounding structure, 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 part 321. The partition plate 11 has a through hole 111, and the connecting terminal 33 passes through the through hole 111 and is inserted 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 remains stable when the fan mechanism 3 is plugged in or unplugged, avoiding unnecessary linkage during unplugging, preventing possible misoperation or interference to the fan plate 2 when plugging in or unplugging the fan mechanism 3, ensuring the independence of the fan plate 2 and the fan mechanism 3 during the plugging and unplugging process, avoiding the risk of system instability or hardware damage caused by accidentally unplugging the fan plate 2, thereby greatly improving the accuracy and safety of the operation.

[0051] In one embodiment, the connecting portion 321 has a third opening on the side opposite to the fan module 31. The third opening is located on the side near the connecting terminal 33, and the fan frame 32 also includes a front cover plate 322, which is detachably connected to the third opening.

[0052] By providing a third opening on the side of the connecting part 321 away from the fan module 31, and by providing the third opening on the side close to the connecting terminal 33, it is convenient for operators to install and remove the connecting terminal 33 through the third opening. Furthermore, by providing a front cover plate 322 detachably connected to the third opening, not only is the opening of the connecting part 321 maintained during the installation and removal of the connecting terminal 33, but it is also ensured that the front cover plate 322 can close the third opening when no operation is being performed, blocking the intrusion of external debris and potential risks, thereby protecting other components inside the fan mechanism 3.

[0053] In a specific embodiment, the fan frame 32 also includes a mounting bracket 325, a connecting portion 321 protruding from the mounting bracket 325, and a front cover plate 322 detachably connected to the mounting bracket 325.

[0054] Specifically, the front cover plate 322 is provided with a first buckle, and the mounting bracket 325 is provided with a slot. The front cover plate 322 is engaged with the slot on the mounting bracket 325 through the first buckle, so as to realize tool-free installation between the front cover plate 322 and the mounting bracket 325.

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

[0056] Specifically, the rear cover plate 326 is provided with a second buckle, and the fan module 31 is provided with a mounting hole. The rear cover plate 326 is engaged with the mounting hole on the fan module 31 through the second buckle, so as to realize tool-free installation between the rear cover plate 326 and the fan module 31.

[0057] In a specific implementation, the mounting bracket 325 is provided with a top plate 324 and a bottom plate 327 on both sides 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 snapped into connection with both the top plate 324 and the bottom plate 327.

[0058] In a specific implementation, 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 mounting slot, and then the connection terminal 33 corresponding to the lower fan unit 311 is snapped into the corresponding mounting slot. 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 cable is fixed by the cable management clip 323. 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, the fan units 311 are arranged sequentially along a first direction, each fan unit 311 is connected to a corresponding connection terminal 33, and the connection terminals 33 are arranged sequentially along a third direction; the first direction, the second direction and the third direction are perpendicular to each other.

[0060] Since the fan module 31 can include multiple fan units 311 and is located within the fan frame 32, it can be plugged into the fan plate 2 through the connecting part 321 of the fan frame 32. This allows for the simultaneous hot-swapping of multiple fan units 311, greatly saving operation time and improving installation and maintenance efficiency. Furthermore, since the multiple fan units 311 are arranged sequentially along the first direction, space is saved in the second and third directions, improving the internal space utilization of the chassis. Also, since the multiple connecting terminals 33 are arranged sequentially along the third direction, mutual interference during installation is avoided, facilitating wiring. Because each fan unit 311 is connected to a corresponding connecting terminal 33, when a fan unit 311 malfunctions and requires repair, it can be handled individually without affecting the normal operation of other fan units 311. This allows for timely repair of faulty fan units 311 without interrupting the overall system operation, 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. Traditional 4U servers use a design with two layers of fan units 311 with a cross-sectional size of 60*60mm. However, when a high-power graphics processor is running, the fan unit 311 with a cross-sectional size of 60*60mm needs to be operated at its maximum speed, resulting in significant noise pollution for the operator's work environment. Furthermore, the heat dissipation performance of the fan unit 311 with a cross-sectional size of 60*60mm is insufficient to meet the heat dissipation requirements of the high-power graphics processor, thus necessitating limitations on the graphics processor's power consumption, thereby restricting the overall performance of the server. If two fan units 311 with a cross-sectional size of 80*80mm are used for heat dissipation, the minimum installation height reaches 161mm. By setting 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 by a cable, and the connection part 321 is provided with a cable clip 323, and the cable is fixed on the cable clip 323.

[0063] When the fan module 31 is running, the cold air it generates can cause the cables to swing uncontrollably. This not only affects the aesthetics of the cable layout but also increases the risk of the cables being accidentally trapped inside the fan unit 311 and damaged, affecting the stability and safety of the system. Therefore, by setting up cable clips 323, the cables can be securely fixed, achieving optimal constraint on the cables with minimal intervention. This ensures the cables have the freedom to meet the necessary flexibility requirements while avoiding the potential risks caused by excessive swinging. It effectively prevents the cables from being damaged by the fan blades due to swinging, optimizes the cable layout, and improves the overall aesthetics and ease of maintenance of the system.

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

[0065] In one embodiment, the fan mechanism 3 further includes a light guide column, and the fan frame 32 has a top plate 324 on the side near the first opening. The top plate 324 has a light guide hole 34, and a fan mark 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 mark 35 are all arranged in a one-to-one correspondence.

[0066] By ensuring that the fan unit 311, light guide column, light guide hole 34 and fan mark 35 are all set up in a one-to-one correspondence, operators can quickly and accurately observe the operating status of each fan unit 311.

[0067] In a specific implementation, each fan unit 311 is equipped with a corresponding light guide column. The light guide column is connected to the status indicator light and other light-emitting elements 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-emitting element can be dynamically adjusted according to the operating status of the fan unit 311, thereby providing operators with intuitive and real-time status feedback.

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

[0070] In a specific implementation, the fan identifier 35 may use specific colors, patterns or text elements to intuitively reflect each corresponding fan unit 311.

[0071] In one embodiment, the mounting frame 1 has a plurality of first mounting slots 12 along a third direction, and each first mounting slot 12 is connected to a first opening. Each first mounting slot 12 is equipped with a set of fan mechanisms 3. The mounting frame 1 has a second mounting slot 13, which is connected to a second opening. The fan plate 2 is disposed in the second mounting slot 13 and extends along a third direction. The multiple sets of fan mechanisms 3 are all inserted into the fan plate 2.

[0072] By setting multiple first mounting slots 12 along a third direction within the mounting frame 1, multiple fan mechanisms 3 can be installed independently at the same time, enabling each fan mechanism 3 to independently perform its heat dissipation function and ensuring that they do not interfere with each other, effectively avoiding performance degradation caused by mutual collision or airflow turbulence; and each fan mechanism 3 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.

[0073] Preferably, a positioning post is provided in the second mounting groove 13, extending along the first direction, and a positioning groove is provided on the side of the fan plate 2 near the fan module 31, extending along the second direction. When the fan plate 2 is slidably installed into the second mounting groove 13 along the second direction, the positioning post and the positioning groove slide together, ensuring that the fan plate 2 can enter the second mounting groove 13 along a predetermined track. After the fan plate 2 is installed in place, the positioning post engages with the bottom of the positioning groove, which not only ensures that the fan plate 2 can be accurately installed in the preset position, but also greatly enhances the connection stability and reliability between the fan mechanism 3 and the fan plate 2, ensuring that the fan mechanism 3 and the fan plate 2 can be smoothly connected.

[0074] In one embodiment, the mounting frame 1 is provided with a force-bearing component, and the fan mechanism 3 further includes a fan handle 36. The fan handle 36 is located on the side where the first opening is located and is rotatably connected to the fan frame 32. The fan handle 36 has a first locking position and a second locking position that are different from the force-bearing component in terms of force-bearing point. When the fan handle 36 is in the first locking position, the rotation of the fan handle 36 assists in the insertion of the fan mechanism 3 into the mounting frame 1; when the fan handle 36 is in the second locking position, the rotation of the fan handle 36 assists in the separation of the fan mechanism 3 from the mounting frame 1.

[0075] By setting the fan handle 36 to cooperate with the force-bearing component, the force required for inserting and removing the fan mechanism 3 can be significantly reduced based on the lever principle. This allows the operator to generate sufficient torque to overcome the resistance during the insertion and removal of the fan mechanism 3 with only a small amount of force input. This not only reduces the force required by the operator but also makes the insertion and removal action smoother and more stable, avoiding mechanical damage or safety hazards caused by excessive or uneven force. Furthermore, it significantly improves the efficiency and convenience of operation, enabling the operator to complete the insertion and removal of the fan mechanism 3 in a shorter time.

[0076] In a specific implementation, a connection terminal 33 has 12 pins, and the fan module 31 has two fan units 311. The two fan units 311 correspond to the two connection terminals 33 respectively. That is, when a fan module 31 is plugged in or unplugged, it needs to overcome the plugging and unplugging force of 24 pins.

[0077] In a specific implementation, the fan handle 36 is made of zinc alloy, which has good casting and mechanical properties.

[0078] In one embodiment, the fan handle 36 includes a first handle 361 and a second handle 362; the first handle 361 includes a first assisting member 3611 and a first connecting plate 3612, the first assisting member 3611 includes a first force-receiving end and a first assisting end arranged sequentially, the first force-receiving end being rotatably connected to one side of the fan frame 32 along a second direction; the first connecting plate 3612 is disposed on the side near the first opening and is connected to the first assisting end; the second handle 362 includes a second assisting member 3621 and a second connecting plate 3622, the second assisting member 3621 includes a second force-receiving end 36211 and a second assisting end 36212 arranged sequentially, the second force-receiving end 36211 being rotatably connected to the other side of the fan frame 32 along a second direction; the second connecting plate 3622 is disposed on the side near the first opening and is connected to the first assisting end; the second handle 3622 is disposed on the side near the first opening and is connected to the first assisting end. The first force-bearing end 36211 is located near the second opening and connected to the second assist end 36212. Two force-bearing components are respectively provided on both sides of the mounting frame 1 along the second direction, with the first force-bearing end and the second force-bearing end 36211 corresponding to the two force-bearing components. The second connecting plate 3622 extends along the second direction and is detachably connected to the first connecting plate 3612 to form an operating component 363. The fan frame 32 has a clearance groove and a top plate 324 on the side near the first opening, with the clearance groove and the top plate 324 adjacent to each other along the third direction. When the fan handle 36 is in the first locking position, the operating component 363 is located in the clearance groove and is parallel to the top plate 324 of the fan frame 32. When the fan handle 36 is in the second locking position, the operating component 363 and the top plate 324 of the fan frame 32 are adjacent to each other along the first direction.

[0079] By setting the first handle 361 and the second handle 362 on both sides of the fan frame 32 along the second direction, and connecting the first handle 361 and the second handle 362 to each other, the overall structural strength of the fan handle 36 is greatly enhanced, thus ensuring its high reliability performance. At the same time, the convenience and efficiency of the fan handle 36 in the assembly process are also significantly improved. Since the side of the fan frame 32 near the first opening is provided with a clearance groove and a top plate 324, and the clearance groove and the top plate 324 are arranged adjacent to each other along the third direction, a safe clearance space is provided for the operating part 363 of the fan handle 36. When the fan handle 36 is in a non-use state, that is, when it is in the first locking position, the operating part 363 is located in the clearance groove and is arranged parallel to the top plate 324 of the fan frame 32. This not only effectively avoids the fan handle 36 occupying extra space when it is not in use, but also ensures the integrity and aesthetics of the appearance of the fan mechanism 3, and avoids collision or interference problems that may be caused by the protrusion of the fan handle 36.

[0080] In a specific implementation, the fan frame 32 is provided with two bushings on both sides along the second direction. The first handle 361 is designed with a first pin, which is located on the side where the first force-bearing end is located. The second handle 362 is designed with a second pin, which is located on the side where the second force-bearing end 36211 is located. The first pin and the second pin are rotatably connected to the two bushings respectively.

[0081] In a specific implementation, when the fan handle 36 is in a non-use state, i.e., in the first locking position, the first assist end and the second assist end 36212 are detachably connected to the fan frame 32 via two fasteners. Specifically, the fasteners can be countersunk screws with a diameter of 3 mm.

[0082] In a specific implementation, the first force-receiving end is provided with a first groove, and the second force-receiving end 36211 is provided with a second groove. The two force-receiving ends are respectively located in the first groove and the second groove, and are respectively engaged with the first groove and the second groove.

[0083] In one embodiment, the fan mechanism 3 further includes a wind direction indicator 37, and the fan frame 32 has a top plate 324 on the side near the first opening, and the wind direction indicator 37 is disposed on the top plate 324.

[0084] By setting a wind direction indicator 37 on the top plate 324 near the first opening of the fan frame 32, the operator can intuitively observe the airflow of the fan mechanism 3 at the first opening, which helps the operator to quickly confirm whether the fan mechanism 3 is operating as expected, and ensures the stability and safety of the overall system.

[0085] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
