Description

Technical Field

[0001] This application relates to the field of server technology, and in particular to a fan module and a server. Background Technology

[0002] In today's big data and cloud computing environment, the demand for high-performance storage and server systems is growing rapidly, leading to an urgent need for efficient heat dissipation solutions. Fan modules, as indispensable heat dissipation components in servers and storage devices, must not only meet the requirements of efficient heat dissipation but also facilitate maintenance and hot-swapping. One proposed technology is a tool-free sandwich-type fan module mechanism that connects and fixes the front panel, fan rotor, and rear frame using fasteners, enabling convenient installation and removal of the fan module. However, this structure suffers from the following significant problems, limiting its widespread application in high-performance equipment:

[0003] On the one hand, in the sandwich fan module mechanism, the tightening force of the fastening connectors can cause deformation of the front window panel and the rear window frame (e.g., bowing effect). This deformation will negatively affect the structural stability of the panel, and long-term stress may cause the front window panel to crack, reducing the service life and reliability of the fan module. On the other hand, the high-speed rotation of the fan blades will generate vibration. If the current rigid fixing method is used, these vibrations will be directly transmitted to other structural components, which will lead to increased noise and decreased performance of the entire device. In high-performance computing environments, the requirements for quiet operation and stability are extremely high. The existing sandwich fan module mechanism cannot meet these requirements, especially when the fan rotor size tolerance is large. The internal stability of the sandwich mechanism will be further affected, which increases the complexity and cost of server maintenance. Utility Model Content

[0004] This application provides a fan module and server to at least solve the problem in the related art where the deformation of components caused by the tightening force of fastening connectors and the vibration transmission caused by rigid fixation reduce the structural stability and quiet performance of the fan module.

The multiple rear window fastening through holes, multiple rotor fastening through holes, multiple first gasket fastening through holes, and multiple front window fastening threaded holes are all provided in a one-to-one correspondence with multiple fastening connectors. The threaded end of each fastening connector passes through the rear window fastening through holes, rotor fastening through holes, and first gasket fastening through holes and is threadedly connected to the front window fastening threaded hole.

[0008] Furthermore, the first elastic gasket includes a first square annular washer, and a plurality of first gasket fastening through holes are correspondingly disposed at a plurality of corners of the first square annular washer.

[0009] Furthermore, the front window assembly is provided with a foolproof protrusion, and the outer peripheral surface of the first elastic gasket is provided with a foolproof opening for interlocking with the foolproof protrusion.

[0010] Furthermore, the thickness of the first elastic gasket ranges from 2mm to 5mm.

[0011] Furthermore, the fan module also includes a second elastic gasket sandwiched between the fan rotor and the rear window assembly.

[0012] Furthermore, the second elastic washer is provided with a plurality of second washer screw through holes at intervals, and the plurality of second washer screw through holes are provided one-to-one with a plurality of fastening fasteners, and each second washer screw through hole is used for the threaded ends of the plurality of fastening fasteners to pass through.

Thus, because the fan module of this application is equipped with a first elastic gasket, the fan rotor located between the front window assembly and the rear window assembly is elastically fixed, effectively reducing the deformation and stress damage caused by the tightening force of the fastening connectors on the front window assembly, fan rotor, and rear window assembly.

[0035] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1 to 9 As shown, this application provides a fan module, including: a front window assembly 1, a fan rotor 2, and a rear window assembly 3, the front window assembly 1, the fan rotor 2, and the rear window assembly 3 being arranged sequentially along a direction parallel to the rotation axis of the fan rotor 2; a first elastic gasket 4, the first elastic gasket 4 being sandwiched between the front window assembly 1 and the fan rotor 2; and a plurality of fastening connectors 5, the plurality of fastening connectors 5 being arranged at intervals around the rotation axis of the fan rotor 2, the threaded end of each fastening connector 5 passing sequentially through the rear window assembly 3, the fan rotor 2, and the first elastic gasket 4 before being connected to the front window assembly 1.

[0037] In this way, the fan module of this application achieves elastic fixation of the fan rotor 2 located between the front window assembly 1 and the rear window assembly 3 by setting the first elastic pad 4. This effectively reduces the deformation and stress damage caused by the tightening force of the fastening connector 5 to the front window assembly 1, the fan rotor 2 and the rear window assembly 3, reduces the mechanical vibration transmission caused by the rigid fixing method, significantly reduces the vibration and noise of the fan module, improves the quietness effect of the fan module, and solves the problem in the related technology that the deformation of the components caused by the tightening force of the fastening connector and the vibration transmission caused by rigid fixing reduce the structural stability and quietness of the fan module. This ensures the structural stability and aesthetic appearance of the fan module, and improves the service life and reliability of the fan module.

[0038] Specifically, a fan module is a modular system specifically designed for internal thermal management of equipment. It combines considerations such as heat dissipation efficiency, noise control, energy efficiency, and ease of maintenance, making it an indispensable component of modern high-performance electronic devices. Fan modules are typically designed for applications requiring efficient heat dissipation, such as servers, computers, electronic devices, and industrial machinery. During operation, they remove heat generated by internal components through forced airflow, maintaining the device's normal operating temperature. The design of fan modules must consider compatibility with different devices, including electrical interfaces, physical dimensions, and installation methods. For ease of maintenance and replacement, fan modules are usually designed to be hot-swappable, meaning they can be safely removed and inserted without shutting down the device. In addition to hot-swapping, fan modules may also feature structures that facilitate cleaning and maintenance, such as removable filters or easily replaceable fans.

[0039] In addition, the fan module of this application is not only applicable to the server field, but can also provide a reliable fan fixing and vibration damping structure for any electronic device or mechanical system that requires efficient heat dissipation and quiet operation, and has broad application prospects and market value.

[0040] like Figure 9As shown, the fastening connector 5 includes a nut 51, a connecting rod 52, and a threaded section 53 connected in sequence. Thus, the fastening connector 5 of this application only needs to be machined a small threaded section 53. Compared with traditional fully threaded fastening connectors, firstly, it greatly reduces the amount of thread machining. Thread machining is one of the most time-consuming and costly processes in precision parts manufacturing, especially for slender parts like fastening connectors. Reducing the thread length means reducing machining difficulty and saving machining time and costs. Secondly, since the threaded section 53 is only located at the end of the fastening connector, the quality of the thread can be controlled more precisely, reducing assembly problems caused by improper thread machining. At the same time, the shorter threaded section 53 also reduces the risk of thread damage during assembly, improving assembly reliability. Thirdly, by precisely controlling the position and length of the threaded section 53, sufficient rigid support can be ensured between the connection point and the remaining non-threaded parts while ensuring connection strength, thereby enhancing the structural stability of the entire fan module. Finally, the presence of threads often causes stress concentration, especially during tightening. By confining the threaded section 53 to the end, stress concentration in the main body of the connecting rod 52 is avoided, which helps to improve the service life of screws and related components. Therefore, the structure of the fastening connector 5 in this application optimizes the manufacturing and assembly process of the fan module in many ways, reduces production costs, improves efficiency and reliability, and also provides support for the improvement of equipment performance.

[0041] Optionally, the fastening connector 5 is a long screw.

[0042] like Figure 4 and Figure 9 As shown, the outer diameter of the connecting rod 52 is larger than the major diameter of the external thread of the threaded section 53, and a stepped surface 54 is formed between the connecting rod 52 and the threaded section 53. The stepped surface 54 is used to contact the end face of the front window assembly 1 on the side near the first elastic gasket 4. In this way, the fastening connector 5 of this application uses the stepped surface 54 to contact the end face of the front window assembly 1 near the first elastic gasket 4, ensuring the size of the internal space between the front window assembly 1 and the nut 51 of the fastening connector 5. This allows the tightening force of the fastening connector 5 to be concentrated at the front window assembly 1, and the tightening force of the fastening connector 5 to be converted into the tightening force in the front window fastening thread hole 11 of the front window assembly 1 and the vertical pressure of the fastening connector 5 on the front window assembly 1. This avoids the direct pulling of the tightening force of the fastening connector 5 on the fan rotor 2 and the front window assembly 1, reduces the impact of the tightening force of the fastening connector 5 on the front window assembly 1 and the fan rotor 2, and enables the front window assembly 1, the fan rotor 2 and the rear window assembly 3 to maintain structural stability during long-term operation, reduces stress damage to the fan module, and improves the structural stability and service life of the fan module.

[0043] Specifically, by contacting the stepped surface 54 with the end face of the front window assembly 1, and in conjunction with the use of the first elastic pad 4, the impact of vibration on the fan rotor 2 can be further reduced. The first elastic pad 4 can absorb some of the vibration energy, while the stepped surface 54 ensures the effective implementation of this energy absorption mechanism and prevents the fan rotor 2 from being subjected to unnecessary mechanical impact, which helps to achieve the quiet operation of the fan module.

[0044] like Figures 6 to 9 As shown, the rear window assembly 3 is provided with a plurality of rear window fastening through holes 31 at intervals, the fan rotor 2 is provided with a plurality of rotor fastening through holes 21 at intervals, the first elastic gasket 4 is provided with a plurality of first gasket fastening through holes 41 at intervals, and the front window assembly 1 is provided with a plurality of front window fastening threaded holes 11 at intervals. The plurality of rear window fastening through holes 31, the plurality of rotor fastening through holes 21, the plurality of first gasket fastening through holes 41 and the plurality of front window fastening threaded holes 11 are all provided in a one-to-one correspondence with the plurality of fastening connectors 5. The threaded end of each fastening connector 5 passes through the rear window fastening through holes 31, the rotor fastening through holes 21 and the first gasket fastening through holes 41 and is threadedly connected to the front window fastening threaded hole 11. In this way, by setting the rear window fastening through hole 31, rotor fastening through hole 21, first gasket fastening through hole 41 and front window fastening threaded hole 11 to cooperate with the fastening connector 5, the fan module is firmly fixed. At the same time, by utilizing the elastic characteristics of the first elastic gasket 4, the fan rotor 2 is elastically buffered and fixed, which improves the structural stability and noise reduction of the fan module and reduces vibration transmission.

[0045] Specifically, in the fan module of this application, there are three fastening connectors 5, and the number of the rear window fastening through hole 31, the rotor fastening through hole 21, the first gasket fastening through hole 41 and the front window fastening threaded hole 11 are also three; the fan module of this application also includes a light guide post 6, and the light guide post 6 and the three fastening connectors 5 are respectively located at the four corners of the fan module.

[0046] This application uses multiple fastening connectors 5 to assemble and connect the various components of the fan module, achieving the following technical advantages:

[0047] (1) Multiple fasteners 5 can be easily disassembled and reassembled when needed, which means that if a part of the fan module needs to be replaced or repaired, it can be done quickly without damaging other structures. This reversibility is especially important for the fan module.

[0048] (2) The connection of multiple fastening connectors 5 can provide sufficient mechanical strength for the fan module and ensure the structural stability of the fan module. By reasonably designing the size, material and fastening torque of the fastening connectors 5, the required durability and fatigue resistance can be achieved, making it suitable for structures that bear high loads.

[0049] (3) The size, length and head type of the multiple fastening connectors 5 are also available in a variety of options, which can be set according to specific connection requirements.

[0050] (4) Compared with other connection methods such as welding and riveting, fastening connection 5 is cheaper in many cases because it does not require special equipment or highly skilled labor and the material cost is relatively low.

[0051] (5) Fastening connector 5 By adjusting the tightening force of fastening connector 5, the gap or pressure between each connecting component can be finely adjusted, which is very important for fan modules.

[0052] Specifically, the fastening connector 5 is made of metal, such as steel, stainless steel, aluminum, or copper alloy, which has high mechanical strength and can withstand large torque and tensile forces, ensuring the stability and reliability of the screw in the fixed connection. The durability of metal screws also far exceeds that of plastic or composite material screws, and they can maintain their original performance for a long time.

[0053] like Figure 8 As shown, the first elastic gasket 4 includes a first square annular washer 42, and a plurality of first gasket fastening through holes 41 are correspondingly arranged at multiple corners of the first square annular washer 42. The first elastic gasket 4 of this application utilizes the structure of the first square annular washer 42 to ensure the fit between the first elastic gasket 4 and the front window assembly 1, the fan rotor 2, and the rear window assembly 3. Simultaneously, the first gasket fastening through holes 41 located at the corners achieve precise alignment with the fastening connector 5, improving the stability of the installation position of the first elastic gasket 4. When compressed, the first elastic gasket 4 can provide a certain holding force for the fan rotor 2 and the rear window assembly 3, reducing the stress deformation of the front window assembly 1, the fan rotor 2, and the rear window assembly 3, and also reducing the shaking of the fan rotor 2 and the rear window assembly 3, thus enhancing the structural stability and noise reduction effect of the fan module.

[0054] Specifically, the first elastic gasket 4 plays a role in buffering and damping vibrations, filling gaps, and compensating for manufacturing tolerances in the fan module. Its material selection must consider elasticity, durability, resistance to compressive deformation, and compatibility with contacting components. The following are some suitable materials for manufacturing the first elastic gasket 4:

[0055] Rubber: Rubber is a common material for elastic gaskets, possessing good elasticity and compression resistance, effectively absorbing vibration and impact. Common types of rubber include natural rubber, nitrile rubber (NBR), silicone rubber, and fluororubber, each exhibiting varying degrees of resistance under different temperatures and chemical environments.

[0056] Polyurethane (PU): Polyurethane elastomers offer a robust yet flexible option that can withstand significant compression and tension without permanent deformation, while also exhibiting good oil and solvent resistance.

[0057] Silicone: Silicone has excellent high and low temperature resistance and is highly adaptable to temperature changes. It also has good electrical insulation and chemical resistance, making it suitable for applications requiring these properties.

[0058] Thermoplastic elastomers (TPEs): such as TPU (thermoplastic polyurethane) and TPEE (thermoplastic polyester elastomer), these materials combine the properties of plastics and rubber, are both moldable and elastic, and are suitable for environments that require rapid production and easy assembly.

[0059] Foam materials, such as polyethylene foam and polyurethane foam, provide lightweight, flexible solutions that can fill irregular gaps while absorbing vibrations and sound.

[0060] Composite materials: Some high-performance elastic gaskets may use composite materials, such as combining rubber or polyurethane with a metal skeleton, to enhance their structural stability and adaptability to complex environments.

[0061] It should be noted that when selecting the material for the first elastic gasket 4, the working environment of the fan module must also be considered, such as the temperature variation range, chemical contact, vibration intensity during operation, electromagnetic compatibility (EMC) requirements, and cost budget. The correct material selection can ensure the long-term stability and optimal performance of the elastic gasket in the fan module.

[0062] like Figure 7 and Figure 8 As shown, the front window assembly 1 is provided with a foolproof protrusion 12, and the outer peripheral surface of the first elastic gasket 4 is provided with a foolproof opening 43 for interlocking with the foolproof protrusion 12. The fan module of this application utilizes the interlocking of the foolproof protrusion 12 and the foolproof opening 43 to prevent incorrect installation of the first elastic gasket 4 during the assembly process, ensuring the correct assembly and operation of the fan module, simplifying the assembly process, and improving the assembly efficiency and accuracy of the fan module.

[0063] Specifically, by setting a foolproof protrusion 12 at a specific position on the front window assembly 1 and a foolproof notch 43 at a corresponding position on the first elastic gasket 4, it can be ensured that the first elastic gasket 4 can only be positioned in the correct way during installation, avoiding installation failure or damage caused by incorrect orientation or position of the first elastic gasket 4. Moreover, the foolproof design can intuitively guide workers to perform quick and error-free assembly without additional inspection steps, reducing the time and labor costs in the assembly process, and also reducing the error rate caused by human negligence. The correct installation method can ensure that all components of the fan module are in the best working condition. The alignment of the foolproof protrusion 12 and the foolproof notch 43 can ensure that the fan is not affected by additional stress during operation, extending the service life of the fan module and enhancing the stability of the fan module.

[0064] Specifically, the thickness of the first elastic shim 4 ranges from 2mm to 5mm. By adjusting the thickness of the first elastic shim 4, this application can compensate for the dimensional tolerances of different fan rotors 2, while achieving a shock absorption effect, improving the adaptability and quietness of the fan module. It is especially suitable for equipment with large dimensional tolerances of the fan rotor 2, avoiding the possibility of the fan rotor 2 shaking when the tolerance is large or the size is small, and the rear window assembly 3 may also shake.

[0065] The fan module of this application also includes a second elastic gasket, which is sandwiched between the fan rotor 2 and the rear window assembly 3. By adding a second elastic gasket between the fan rotor 2 and the rear window assembly 3, the fan module of this application further enhances the elastic fixing effect of the fan rotor 2, while better compensating for the dimensional tolerances of the fan rotor 2, reducing the transmission of vibration to the fan rotor 2, and improving the structural stability and noise reduction of the fan module. It is suitable for all equipment requiring fan modules, such as servers, workstations, and network equipment, and is especially suitable for equipment in high-vibration environments.

[0066] The second elastic washer is provided with a plurality of second washer screw through holes at intervals. The plurality of second washer screw through holes are provided one-to-one with a plurality of fastening fasteners 5. Each second washer screw through hole is used to allow the threaded ends of the plurality of fastening fasteners 5 to pass through.

[0067] The second elastic gasket of this application includes a second square annular washer, and multiple second gasket screw through holes are correspondingly arranged at multiple corners of the second square annular washer. This ensures the fit between the second elastic gasket and the front window assembly 1, the fan rotor 2 and the rear window assembly 3. At the same time, it achieves precise alignment between the second elastic gasket and the fastening connector 5, improves the stability of the installation position of the second elastic gasket, further reduces the shaking of the fan rotor 2, and enhances the structural stability and noise reduction effect of the fan module.

[0068] The fan module of this application includes the following embodiments:
