Description

[0001] This application claims priority to Chinese Patent Application No. 202521187117.5, filed on June 11, 2025, entitled "Vibration Reduction Structure and Server", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of server equipment technology, and in particular to a vibration reduction structure and a server. Background Technology

[0003] A server is a specific IT device that provides computing power and runs software applications in a network environment. It provides computing or application services to other client devices (such as personal computers, smartphones, and other terminal devices) on the network. Over the years, in order to meet the increasingly high demands for high-speed signal transmission, servers have had to continuously iterate and upgrade through design optimization to meet the ever-increasing reliability requirements of server hard drive storage.

[0004] In server system design, there exists a delicate balance between computing performance, power consumption, heat dissipation, fan noise, storage capacity, disk density, and read / write performance. Improving server computing performance increases power consumption, which necessitates enhanced heat dissipation, which in turn requires increased cooling fan speeds. However, increasing cooling fan speeds limits the potential for increased hard drive storage density because the noise and sound pressure generated by the fans within the chassis can cause resonance in the delicate components inside the server hard drive, affecting read / write performance.

[0005] Therefore, in order to improve the reliability of server hard drive storage, it is necessary to control server hard drive vibration and reduce the impact of server hard drive vibration on hard drive read and write performance. Utility Model Content

[0006] This application provides a vibration reduction structure and a server to solve the technical problem that the noise and sound pressure generated by the cooling fan of an existing server can cause resonance of precision components inside the server hard drive, affecting the read and write performance of the hard drive.

[0007] According to the first aspect disclosed in this application, this application provides a vibration damping structure, including one or more perforated plates, wherein the perforated plates are provided with a plurality of through holes; the perforated plates are disposed inside the chassis of a server, and the perforated plates are located between the cooling fan and the hard drive assembly inside the chassis.

[0008] In one feasible implementation, the perforated plate is provided with a plurality of extension tubes, and the extension tubes are connected to the through holes one by one.

[0009] In one feasible implementation, the gaps between the extension tubes are filled with sound-absorbing cotton.

[0010] In one feasible implementation, the through hole corresponds to the position of the gap left between the hard drives in the hard drive group.

[0011] In one feasible implementation, the vibration damping structure further includes one or more layers of mesh, which are disposed inside the chassis and located between the perforated plate and the hard drive assembly.

[0012] In one feasible implementation, multiple perforated plates are spaced apart.

[0013] In one feasible implementation, the through holes corresponding to the positions of the multiple perforated plates are connected by an extension pipe.

[0014] According to the second aspect disclosed in this application, this application provides a server, including a chassis, a motherboard, a cooling fan and a hard drive assembly, as well as a vibration damping structure as described in any one of the first aspects;

[0015] The motherboard, the cooling fan, and the hard drive assembly are housed inside the chassis, which has multiple ventilation openings.

[0016] In one possible implementation, the chassis includes a cover and a housing, the cover being used to close the housing.

[0017] In one feasible implementation, a dustproof net is provided at the vent.

[0018] Compared with the prior art, this application has the following advantages:

[0019] This application provides a vibration damping structure and server. By installing a perforated plate inside the server chassis, positioned between the cooling fan and the hard drive assembly, the perforated plate isolates part of the fan noise, thereby reducing hard drive vibration by decreasing the noise transmitted from the cooling fan to the hard drive. Simultaneously, because the perforated plate has multiple through-holes, it can rectify airflow without affecting the cooling fan's ventilation, breaking large-scale vortices in the airflow into smaller ones, making the airflow in front of the cooling fan more uniform, further reducing cooling fan noise, and thus reducing hard drive vibration. The vibration damping structure, including the perforated plate, reduces the sound pressure level of noise transmitted to the hard drive assembly through sound insulation and rectification, thereby preventing noise from the cooling fan from causing resonance in the precision components inside the server hard drive, reducing hard drive vibration, and improving the read / write performance of the server hard drive.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0046] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0047] A server is a specific IT device in a network environment that provides computing power and runs software applications. It provides computing or application services to other client machines (such as personal computers, smartphones, and other terminal devices) on the network. Generally, servers have the ability to respond to service requests, provide services, and ensure service availability. Compared to ordinary computers, servers have high-speed CPU processing power; long-term reliable operation capability; powerful I / O data throughput capability; and high scalability.

[0048] Over the years, server hard drives have seen significant improvements in storage density and rotational speed, while PCBA chips have become increasingly numerous, with higher density and integration. Simultaneously, the demand for high-speed signal transmission has increased for AI servers, network switches, and multi-processor servers, forcing servers to continuously iterate and upgrade through design optimization to meet the ever-increasing reliability requirements of server hard drive storage.

[0049] See Figure 1A typical server includes a chassis 100, and within the chassis 100, a motherboard 400, a cooling fan 300, and a hard drive assembly 200, which comprises multiple server hard drives. As a mechanical structure, the server hard drive itself vibrates during head extension and retraction for addressing and platter rotation, impacting read / write performance. Current servers typically mitigate this vibration through internal active control mechanisms (identifying and correcting positional deviations). Server system design involves a delicate balance between computing performance, power consumption, heat dissipation, fan noise, storage capacity, disk density, and read / write performance. Increasing server computing performance increases power consumption, necessitating improved cooling, which in turn requires increasing the speed of the cooling fan 300; some servers have even increased the fan speed to 34,000 RPM. However, increasing the fan speed limits the increase in hard drive storage density because the noise generated by the cooling fan 300 within the chassis 100 can cause resonance in the delicate components inside the server hard drive, affecting read / write performance. Therefore, in order to improve the reliability of server hard drive storage, it is necessary to control server hard drive vibration and reduce the impact of server hard drive vibration on hard drive read and write performance.

[0050] Traditional measures to suppress server hard drive vibration mainly include optimizing the blades of the cooling fan 300, installing sound-absorbing cotton 504 between the hard drive and the cooling fan 300, and adding a honeycomb rectifier in front of the cooling fan 300. However, while optimizing the blades of the cooling fan 300 can reduce the noise of the cooling fan 300 and thus reduce hard drive vibration, it still cannot solve the problem of server hard drive failure caused by the noise of the cooling fan 300. Due to the limited space between the hard drive and the cooling fan 300, and the fact that the sound-absorbing cotton 504 installed between the hard drive and the cooling fan 300 cannot affect the airflow of the cooling fan 300, the sound-absorbing cotton 504 solution is also difficult to achieve a good vibration reduction effect. Adding a honeycomb rectifier in front of the cooling fan 300 can only slightly reduce the noise of the cooling fan 300, and its vibration reduction effect on the hard drive is also very limited.

[0051] To address the aforementioned technical issues, this application proposes a vibration-damping structure and server. While maintaining heat dissipation, the perforated plate 501 reduces the noise pressure propagating to the hard drive assembly 200 through its sound insulation and rectification functions. This prevents the noise generated by the cooling fan 300 from causing resonance in the precision components inside the server hard drive, reduces hard drive vibration, and improves the read and write performance of the server hard drive.

[0052] The technical solutions for the vibration reduction structure and server provided in this application will be described in detail below through specific embodiments. It should be noted that the following embodiments may exist independently or in combination with each other, and the same or similar content may not be described again in different embodiments.

[0053] See Figure 2 and Figure 3 In some embodiments, the vibration damping structure 500 includes one or more perforated plates 501, with multiple through holes 503 provided on the perforated plates 501; the perforated plates 501 are disposed inside the server chassis 100, and the perforated plates 501 are located between the cooling fan 300 and the hard disk assembly 200 inside the chassis 100.

[0054] In this embodiment, by installing a perforated plate 501 inside the server chassis 100 and placing it between the cooling fan 300 and the hard drive assembly 200 within the chassis 100, the perforated plate 501 can isolate some of the fan noise, thereby reducing hard drive vibration by lowering the noise transmitted from the cooling fan 300 to the hard drive. Simultaneously, since the perforated plate 501 has multiple through holes 503, it can rectify the airflow without affecting the ventilation and heat dissipation of the cooling fan 300, breaking large-scale vortices in the airflow into smaller ones, making the incoming airflow in front of the cooling fan 300 more uniform, further reducing the noise of the cooling fan 300, and thus reducing hard drive vibration. The vibration damping structure 500, including the perforated plate 501, reduces the sound pressure transmitted to the hard drive assembly 200 through sound insulation and rectification, thereby preventing the noise generated by the cooling fan 300 from causing resonance in the precision components inside the server hard drive, reducing hard drive vibration, and improving the read / write performance of the server hard drive.

[0055] In addition to its excellent vibration reduction effect, the vibration reduction structure 500 based on the perforated plate 501 also has the advantages of small space occupation, applicability to servers with limited space, low cost, and easy installation and replacement.

[0056] Specifically, the perforated plate 501 can be installed inside the chassis 100 using screws, slots, or other structures.

[0057] Specifically, since the perforated plate 501 includes through holes 503, the heat dissipation of the hard drive will not be affected if the perforation area of ​​the perforated plate 501 is large enough.

[0058] See Figure 4 Specifically, the shape and arrangement of the through hole 503 can be set arbitrarily. For example, the shape of the through hole 503 can be circular, hexagonal, rectangular, triangular, etc.

[0059] Specifically, the vibration damping effect on the hard drive can be altered by adjusting the perforation ratio (the ratio between the area of ​​the through hole 503 and the area of ​​the perforated plate 501), the size of the through hole 503, and the shape of the opening. For example, a smaller perforation ratio of the perforated plate 501 results in higher sound insulation, better rectification, and better vibration damping for the hard drive. However, too small a perforation ratio can negatively impact the hard drive's heat dissipation. Therefore, the perforation ratio of the perforated plate 501 should be minimized while ensuring adequate heat dissipation for the hard drive.

[0060] The vibration damping and heat dissipation effects of the hard drive can be adjusted by replacing the perforated plate 501 with one of different perforation rates.

[0061] See Figure 3 Optionally, the perforated plate 501 is provided with multiple extension tubes 502, and the extension tubes 502 are connected to the through holes 503 one by one.

[0062] By connecting the extension tube 502 at the through hole 503, the narrow area of ​​the extension tube 502 can be used to further dissipate the noise of the cooling fan 300, reduce the noise of the cooling fan 300, and thus reduce the vibration of the hard drive.

[0063] Specifically, the longer the extension tube 502, the better its sound energy dissipation effect. Therefore, by adjusting the length of the extension tube 502, the sound insulation and rectification effects of the perforated plate 501 can be changed, thereby improving the vibration reduction effect of the hard drive.

[0064] See Figure 5 Optionally, the gaps between the extension tubes 502 are filled with sound-absorbing cotton 504.

[0065] Due to the porous sound-absorbing material properties that constitute the sound-absorbing cotton 504, when sound waves impact the surface of the sound-absorbing cotton 504, some energy enters the interior of the porous sound-absorbing material. The sound waves are reflected and scattered multiple times within the pores of the porous sound-absorbing material, and friction occurs with the pore walls. This friction converts the sound wave energy into heat energy, which is ultimately absorbed by the porous sound-absorbing material. By placing the sound-absorbing cotton 504 in the gaps between the extension tubes 502, the sound-absorbing cotton 504 will not block the through holes of the extension tubes 502, thus not affecting the heat dissipation effect. Furthermore, the sound-absorbing cotton 504 can absorb the noise of the cooling fan 300, further reducing noise and minimizing hard drive vibration.

[0066] Specifically, the 504 sound-absorbing cotton material can be made of melamine, polyurethane, polyester fiber, glass fiber, rock wool, foam, etc.

[0067] Optionally, the through hole 503 corresponds to the position of the gap left between the hard drives in the hard drive group 200.

[0068] In the case of the hard drive group 200 installed in the server, to ensure that each hard drive in the hard drive group 200 has good heat dissipation performance, gaps are left between the hard drives when multiple hard drives are installed. The through holes 503 on the perforated plate 501 are aligned with the positions of the gaps left by the hard drives, so that the through holes 503 and the gaps between the hard drives can form a straight airflow channel that is conducive to ventilation, thereby improving the heat dissipation performance of the hard drives.

[0069] See Figure 6 Optionally, the vibration damping structure 500 may also include one or more layers of mesh 505, which are disposed inside the chassis 100 and located between the perforated plate 501 and the hard drive assembly 200.

[0070] The combination of the mesh 505 and the perforated plate 501 allows for more uniform airflow from the cooling fan 300, further reducing fan noise and consequently minimizing hard drive vibration. It should be noted that the finer the mesh and the more layers the mesh 505 has, the better the airflow rectification effect.

[0071] Optional, multiple perforated plates 501 spaced apart.

[0072] By setting multiple perforated panels 501 spaced apart, with air layers between them, the sound insulation effect can be improved and the noise transmitted to the hard disk assembly 200 can be reduced by reasonably setting the parameters of the perforated panels 501 and the thickness of the air layers. In addition to the air layers, sound-absorbing cotton 504 can be filled between the perforated panels 501. The sound-absorbing cotton 504 needs to have airflow passages with through holes 503, thus forming a composite structure using the perforated panels 501 and the sound-absorbing cotton 504. By utilizing the sound insulation properties of different materials, the overall sound insulation effect can be improved.

[0073] See Figure 7 Optionally, the through holes 503 corresponding to the positions of multiple perforated plates 501 are connected by extension tubes 502.

[0074] In this process, the through holes 503 corresponding to the positions of multiple perforated plates 501 are connected by extension tubes 502, thereby utilizing the narrow area formed by the extension tubes 502 to further dissipate the acoustic energy of the cooling fan 300 noise and enhance the vibration reduction effect of the perforated plates 501.

[0075] See Figure 2 , Figure 8 and Figure 9 In some embodiments, the server includes a chassis 100, a motherboard 400, a cooling fan 300, and a hard disk assembly 200, as well as the aforementioned vibration damping structure 500; the motherboard 400, the cooling fan 300, and the hard disk assembly 200 are disposed within the chassis 100, and the chassis 100 is provided with a plurality of ventilation openings 103.

[0076] In this embodiment, during server use, the chassis 100 protects the internal hardware of the server and provides heat dissipation channels through multiple ventilation openings 103 provided on the chassis 100. The ventilation openings 103 and the cooling fan 300 work together to form an efficient airflow system, ensuring that heat inside the chassis 100 is dissipated in a timely manner. The motherboard 400 is used to integrate and connect the server hardware (such as CPU, GPU, memory, etc.). The cooling fan 300 is used to reduce the temperature of the hardware inside the chassis 100 and prevent overheating and frequency throttling. The hard drive is used to store data.

[0077] The vibration damping structure 500 is located between the cooling fan 300 and the hard drive assembly 200. Without affecting the ventilation and heat dissipation of the cooling fan 300, it reduces hard drive vibration by lowering the noise transmitted from the cooling fan 300 to the hard drive assembly 200, thus achieving a vibration damping effect. This prevents the noise generated by the cooling fan 300 from causing resonance in the precision components inside the server hard drive, improving the hard drive's read and write performance.

[0078] Specifically, the installation location of the cooling fan 300 should ensure the formation of an effective airflow, allowing cool air to smoothly enter the chassis 100 and hot air to be quickly exhausted. The installation location of the cooling fan 300 should take into account the layout of the server's internal hardware to ensure that critical hardware (such as the CPU, GPU, memory, hard drive, etc.) receives sufficient cooling. Therefore, the position of the cooling fan 300 can be flexibly adjusted according to the internal hardware layout of the chassis 100.

[0079] See Figure 3 Optionally, the chassis 100 includes a cover plate 101 and a housing 102, with the cover plate 101 used to enclose the housing 102; the motherboard 400, cooling fan 300 and hard drive assembly 200 are installed inside the housing 102.

[0080] The system incorporates a cover plate 101 and a chassis 102. The chassis 102 provides standardized installation positions and supports modular design, facilitating the installation, upgrading, and maintenance of hardware such as the motherboard 400, cooling fan 300, and hard drive assembly 200. The cover plate 101 can be combined with the chassis 102 to form a chassis 100, providing outer shell protection for the motherboard 400, cooling fan 300, and hard drive assembly 200 to prevent physical damage such as impacts and compression. Furthermore, the hardware inside the chassis 102 can be inspected and maintained by removing the cover plate 101, improving server maintenance efficiency.

[0081] In addition, since the chassis 100 is generally made of metal, it can reduce the impact of electromagnetic interference on the internal hardware of the chassis 100, and can also isolate some of the electromagnetic waves radiated outward by the internal hardware.

[0082] Specifically, the cover plate 101 and the box body 102 can be fixedly connected by screws, clips or other structures.

[0083] Optionally, a dustproof screen is installed at the ventilation opening 103.

[0084] By installing a dust filter at the ventilation opening 103, the dust filter physically intercepts dust, hair, and other impurities through its dense mesh structure (typically with a pore size of 1-3mm), preventing them from entering the chassis 100. This helps maintain the cleanliness of the chassis 100's interior, ensuring the proper functioning of the cooling fan 300 and creating a stable heat dissipation environment. A stable heat dissipation environment maintains stable hardware performance, preventing performance degradation or hardware damage due to overheating. This ensures stable server hardware operation and extends the server's lifespan.

[0085] Specifically, dustproof nets can be made of metal wire mesh, fiber filter mesh, etc.

[0086] Based on the above embodiments, this application proposes a server with a vibration damping structure 500, and uses finite element analysis to calculate the sound pressure level at the center point of the front and rear hard disk arrays 200. Specifically, a perforated plate 501 is provided between the server's cooling fan 300 and the hard disk arrays 200. The thickness of the perforated plate 501 is set to 1.5 mm, the diameter of the through holes 503 on the perforated plate 501 is set to 1 mm, the perforation rate is set to 1%, the length of the extension tube 502 is set to 5 mm, and the noise source of the cooling fan 300 uses four surface sound sources with a sound pressure level of 1 Pa.

[0087] See Figure 10 The test results show that, compared with the server without vibration damping structure 500, the server with vibration damping structure 500 proposed in this application embodiment has a very significant reduction in sound pressure level at the center point of hard disk group 200 in the 1900~2600Hz frequency band, indicating that the vibration damping structure 500 provided in this application embodiment has a good vibration damping effect on the server hard disk in this frequency band.
