Description

Technical Field

[0001] This application relates to the field of server technology, and more particularly to a chassis assembly and a server. Background Technology

[0002] Currently, with the rapid development of cloud computing and big data technologies, the processing power and storage requirements of servers are increasing daily, leading to a significant increase in the power consumption of server internal hardware, especially the CPU. To ensure stable server operation, heat dissipation has become a critical aspect of the design. However, server internal space is limited, especially the layout of 3.5-inch hard drives and cooling fans, which is significantly constrained by space limitations.

[0003] In existing technologies, common solutions fall into two categories. The first solution is to increase the distance between the fan and the hard drive, hoping that noise energy will decrease after traveling a longer distance, thus mitigating the noise's impact on the hard drive. The second solution is to add a honeycomb-like air guide device at the fan outlet. This device is hollow and contains honeycomb-shaped holes. When the airflow from the fan passes through this air guide device, the airflow is cut by the holes, which can help reduce the noise's impact on the hard drive.

[0004] However, in the first solution, the server modules are designed very compactly, leaving very limited space for adjusting the fan and hard drive spacing. Adjusting the distance between the fan and hard drive within such a small range has little effect on reducing the noise impact on the hard drive. In the second solution, while reducing noise, the device reduces the fan's airflow, thus affecting the solution to the heat dissipation problem. At this point, the heat dissipation designer will continue to increase the fan speed to compensate for the reduced airflow, but increasing the fan speed will increase noise, often resulting in more harm than good.

[0036] 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.

[0037] Currently, in existing technologies, the noise from the cooling fans inside the computer case has a significant impact on hard drive performance. This issue is primarily mitigated by increasing the physical distance between the fan and the hard drive, or by adding airflow guides to the front of the fan. However, these two methods are either difficult to implement within the space-constrained environment of a server, or they sacrifice the fan's cooling efficiency. Ultimately, neither method fundamentally solves the noise problem and may introduce additional issues.

[0038] like Figures 1 to 7As shown, this application provides a chassis device, including: a chassis body 10 having a heat sink wall, and a cooling fan disposed inside the chassis body 10 near the heat sink wall; a mounting assembly 20 disposed inside the chassis body 10 opposite to the heat sink wall, the chassis body 10 including an inner wall structure located between the heat sink wall and the mounting assembly 20, the heat sink wall, the mounting assembly 20 and the inner wall structure forming a noise reduction space, the cooling fan being located in the noise reduction space and facing the mounting assembly 20, and a hard drive being mounted on the side of the mounting assembly 20 away from the noise reduction space; a first noise reduction assembly 30 disposed on at least a portion of the mounting assembly 20; and a second noise reduction assembly 40 disposed on at least a portion of the inner wall structure, so as to absorb the noise emitted by the cooling fan in the noise reduction space through the first noise reduction assembly 30 and the second noise reduction assembly 40.

[0039] This application establishes a noise reduction space between the hard drive mounting component 20 and its rear inner wall structure within the chassis. A first noise reduction component 30 and a second noise reduction component 40 are strategically positioned within this space to directly absorb and reduce noise near the noise source and along its propagation path. This significantly absorbs noise generated by the cooling fan, reducing noise propagation and reflection within the chassis, without affecting the normal ventilation and heat dissipation of the cooling fan. This design not only reduces the direct impact of noise on the hard drive, ensuring its high-performance operation, but also reduces hard drive vibration caused by cooling fan noise, helping to extend the hard drive's lifespan and maintaining good thermal management within the server. It provides a highly efficient solution that comprehensively considers both heat dissipation and noise reduction. In particular, this solution does not require significant adjustments to the server's internal layout, nor does it rely on increasing fan speed to compensate for heat loss, thus exhibiting significant advantages in terms of structural compactness and economy. Furthermore, the first noise reduction component 30 and the second noise reduction component 40 can be flexibly adjusted and customized according to different server architectures and hard drive layouts, making it suitable for various models and specifications of hard drives, enhancing the adaptability and expandability of the chassis.

[0040] Therefore, this technology can at least solve the technical problem that the noise of the cooling fan inside the chassis has a significant impact on hard drive performance, achieving the technical effect of reducing the impact of cooling fan noise on hard drive performance without affecting normal hard drive cooling.

[0041] In this embodiment, the mounting component 20 includes: a mounting bracket 21 connected to a portion of the inner wall of the chassis 10; a hard disk backplate 22 disposed on the mounting bracket 21; at least a portion of the first noise reduction component 30 disposed on the side of the hard disk backplate 22 facing the noise reduction space; and at least another portion of the first noise reduction component 30 disposed on the mounting bracket 21.

[0042] The aforementioned configuration, with the first noise reduction component 30 positioned on the hard drive backplate 22 and mounting bracket 21, absorbs and reduces fan noise from multiple directions, forming a noise barrier surrounding the hard drive, thereby more effectively reducing the impact of noise on hard drive performance. Since the hard drive is directly connected to the hard drive backplate 22, placing a portion of the first noise reduction component 30 on its side facing the noise reduction space directly protects the hard drive from frontal noise impact, reduces hard drive vibration, and improves data read / write stability. Because the hard drives on the hard drive backplate 22 closest to the inner wall of the chassis 10 are more affected by cooling fan noise than other hard drives, placing another portion of the first noise reduction component 30 on the mounting bracket 21 reduces the impact of cooling fan noise on these drives. Therefore, the design of the first noise reduction component 30 effectively reduces the performance impact on all hard drives on the hard drive backplate 22 without obstructing the cooling fan's heat dissipation path.

[0043] In this embodiment, the hard drive backplane 22 is 3.5 inches.

[0044] like Figure 3 and Figure 4 As shown, the first noise reduction component 30 includes: a plurality of first noise reduction elements 31, which are respectively and spaced apart on the side of the hard disk backplate 22 facing the noise reduction space and avoiding the components on the hard disk backplate 22; a plurality of hard disks are arranged on the side of the hard disk backplate 22 away from the noise reduction space and are arranged one-to-one with the positions of the plurality of first noise reduction elements 31; at least two second noise reduction elements 32, among which the plurality of hard disks include a first hard disk and a second hard disk that are relatively far apart; one of the at least two second noise reduction elements 32 is arranged at one end of the mounting bracket 21 and close to the first hard disk; the other of the at least two second noise reduction elements 32 is arranged at the other end of the mounting bracket 21 and close to the second hard disk; at least a portion of the second noise reduction elements 32 forms a ventilation channel through which the airflow blown by the cooling fan passes.

[0045] In this way, the multiple first noise reduction components 31 are spaced apart and arranged to avoid interference with the components on the hard drive backplane 22. This effectively covers most of the area of ​​the hard drive backplane 22 to absorb noise, while precisely avoiding critical components without affecting their functionality. At the same time, the first noise reduction components 31 correspond one-to-one with the hard drive positions, enabling direct noise reduction in noise-sensitive areas and improving efficiency.

[0046] On the side of the hard drive backplate 22 away from the noise reduction space, the first and second hard drives, which are relatively far away from and close to the inner wall of the chassis 10, are the hard drives most affected by noise. By placing second noise reduction components 32 near these two hard drives at both ends of the mounting bracket 21, these sensitive hard drives can be given special attention and protection, preventing their performance from being damaged by excessive noise. The placement of the second noise reduction components 32 not only takes into account the noise reduction effect, but also forms a ventilation channel for the airflow blown by the cooling fan. This design ensures that even in the presence of the first noise reduction component 30, the ventilation and heat dissipation path of the cooling fan remains unobstructed, and will not negatively affect the overall heat dissipation efficiency of the system.

[0047] Specifically, the first noise reduction component 31 is provided with a first clearance groove 310 and / or clearance hole 311. The shape of the first clearance groove 310 and / or clearance hole 311 projected onto the hard disk backplane 22 is consistent with the shape of the components on the hard disk backplane 22. This design, when creating the first noise reduction component 31, also needs to consider clearance from important chips, cable connectors, and cable connector reference markings on the hard disk backplane 22. To achieve this, the outlines of the important chips, cable connectors, and cable connector reference markings on the hard disk backplane 22 are projected onto the plane where the first noise reduction component 31 is located, obtaining their projected outlines on the first noise reduction component 31. Then, using laser cutting, the corresponding foam is cut along the outline to form the first clearance groove 310 and / or clearance hole 311 for proper clearance. This not only protects the normal operation of the hard disk backplane 22 but also improves the installation accuracy and reliability of the first noise reduction component 31.

[0048] In this embodiment, a first positioning mark is provided on the hard disk backplane 22, and at least a portion of the outer edge of the first noise reduction component 31 is correspondingly positioned to the first positioning mark. When assembling the hard disk backplane 22 and the first noise reduction component 31, a good positioning operation is required; therefore, the first positioning mark is added to the hard disk backplane 22. When bonding the first noise reduction component 31, aligning one corner or one side of the first noise reduction component 31 with the first positioning mark completes the positioning operation of the first noise reduction component 31.

[0049] Optionally, the first positioning mark is a protruding structure protruding from the surface of the hard disk backplate 22. The positioning and installation of the first noise reduction component 31 can be achieved by contacting or abutting one corner or one side of the protruding structure.

[0050] In this embodiment, a first adhesive layer is provided on the side of the first noise reduction component 31 facing the hard disk backplane 22 for bonding to the hard disk backplane 22. The first adhesive layer has strong bonding performance and high resistance to heat attenuation. Since the internal temperature of the server rises after a period of operation, the first adhesive layer ensures a firm bond between the first noise reduction component 31 and the hard disk backplane 22, preventing the first noise reduction component 31 from detaching or shifting due to vibration during server operation, thereby ensuring the stability and long-term reliability of the first noise reduction component 31.

[0051] Specifically, the second noise reduction component 32 includes: a first connecting segment 320, a second connecting segment 321, and a third connecting segment 322 connected in sequence in a U-shape. The first connecting segment 320 and the third connecting segment 322 are located on the same side of the second connecting segment 321 and are arranged parallel to each other. The end of the first connecting segment 320 away from the second connecting segment 321 is provided with a bent segment that moves towards the third connecting segment 322 to adapt to at least a part of the shape of the mounting bracket 21. The hard disk has a preset length L along the extension direction of the hard disk backplate 22, the mounting bracket 21 has a preset height H and a preset width D, and the length a1 and width b1 of the second noise reduction component 32 satisfy: a1=2L+H, 0.4D≤b1≤0.6D.

[0052] With the above configuration, the second noise reduction component 32 of the U-shaped structure forms a local space around the connection between the edge of the hard disk backplate 22 and the mounting bracket 21 through the first connecting section 320, the second connecting section 321 and the third connecting section 322. It can directly face the noise propagation path, focus on protecting the hard disk that is most affected by noise, and ensure that the airflow blown out by the cooling fan can flow along the predetermined path. This protects the hard disk from noise interference without hindering heat dissipation, thus maintaining good thermal management inside the server.

[0053] In this embodiment, the first connecting segment 320 and the third connecting segment 322 are perpendicularly connected to the second connecting segment 321, and the first connecting segment 320 and the third connecting segment 322 are arranged parallel to each other. The first connecting segment 320, the second connecting segment 321, and the third connecting segment 322 are adapted to the partial shape of the mounting bracket 21, and are tightly fitted to the mounting bracket 21 through the bending section on the first connecting segment 320. This not only increases the stability of the structure and prevents the second noise reduction component 32 from resonating due to fan vibration, but also further enhances the noise reduction effect, ensuring the reliability and durability of the second noise reduction component 32 during server operation. At the same time, the length a1 and width a2 of the second noise reduction component 32 are precisely set based on the preset length L of the hard drive, the preset height H and the preset width D of the mounting bracket 21, respectively. This meticulous control of dimensions ensures a perfect fit between the second noise reduction component 32 and the internal structure of the mounting bracket 21, improving compatibility and applicability.

[0054] In this embodiment, a second positioning mark is provided on the mounting bracket 21, and at least a portion of the outer edge of the second noise reduction component 32 is correspondingly positioned with the second positioning mark. Good positioning is required when assembling the mounting bracket 21 and the second noise reduction component 32; therefore, a second positioning mark is added to the mounting bracket 21. When bonding the second noise reduction component 32, aligning one corner or one side of the second noise reduction component 32 with the second positioning mark completes the positioning operation of the second noise reduction component 32.

[0055] Optionally, the second positioning mark is a protruding structure protruding from the surface of the mounting bracket 21. By contacting or abutting one corner or one side of the second noise reduction component 32 with the protruding structure, the positioning and installation of the second noise reduction component 32 can be achieved.

[0056] In this embodiment, a second adhesive layer is provided on the side of the second noise reduction component 32 facing the mounting bracket 21 for bonding with the mounting bracket 21. The second adhesive layer has strong adhesive properties and high resistance to heat attenuation. Since the internal temperature of the server rises after a period of operation, the second adhesive layer ensures a firm bond between the second noise reduction component 32 and the mounting bracket 21, preventing the second noise reduction component 32 from detaching or shifting due to vibration during server operation, thereby guaranteeing the stability and long-term reliability of the second noise reduction component 32.

[0057] like Figure 1 , Figure 2 and Figures 5 to 7 As shown, the inner wall structure includes a top wall, a bottom wall, and two side walls. The second noise reduction component 40 includes: a third noise reduction component 41, which is disposed on the top wall and avoids the protruding structure on the mounting component 20; a fourth noise reduction component 42, which is disposed on the bottom wall and avoids the protruding structure on the mounting component 20; and two fifth noise reduction components 43, which are respectively disposed on the two side walls.

[0058] The aforementioned configuration, with the third noise reduction component 41, the fourth noise reduction component 42, and the two fifth noise reduction components 43 respectively positioned on the top, bottom, and side walls of the chassis 10, forms a noise reduction space that completely surrounds the cooling fan. This effectively absorbs and reduces fan noise from all directions, significantly improving noise reduction performance. Simultaneously, these noise reduction components are designed to avoid protruding structures on the mounting components 20, such as hard drive connectors and power cable interfaces, preventing interference with the normal operation and maintenance of the server's internal hardware and ensuring the integrity of server functions and ease of operation. Furthermore, through precise design, the second noise reduction component 40 fits tightly against the inner wall structure of the chassis 10, maximizing coverage of the inner wall structure while avoiding the mounting components 20. This ensures unobstructed heat dissipation paths within the server, allowing unimpeded airflow from the fan and effectively absorbing and reducing noise generated by the cooling fan within the noise reduction space.

[0059] Specifically, the third noise reduction component 41 is provided with a plurality of second clearance grooves 410 at intervals along its extension direction. The shape of the second clearance grooves 410 projected onto the top wall is consistent with the shape of the protrusions on the mounting assembly 20. This arrangement is necessary because, when designing the third noise reduction component 41, clearance from protrusions on the mounting bracket 21 must also be considered. To achieve this, the outline of the protrusions on the mounting bracket 21 is projected onto the plane of the third noise reduction component 41 to obtain its projected outline on the third noise reduction component 41. Then, using laser cutting, the corresponding foam is cut away along the outline to form the second clearance grooves 410 for proper clearance. This not only protects the normal operation of the mounting bracket 21 but also improves the installation accuracy and reliability of the third noise reduction component 41.

[0060] In this embodiment, there is a preset distance h1 between the two sidewalls, and a preset distance h2 between the mounting component 20 and the cooling fan. The length a2 and width b2 of the third noise reduction component 41 satisfy a2 = h1 and b2 = h2, respectively. With the above configuration, the length a2 and width b2 of the third noise reduction component 41 are strictly designed according to the preset distances h1 and h2 between the top wall and the mounting component 20 and the cooling fan. This precise dimensional control maximizes the use of available space while ensuring the coverage and noise reduction performance of the third noise reduction component 41.

[0061] In this embodiment, a third positioning mark is provided on the top wall, and at least a portion of the outer edge of the third noise reduction component 41 is correspondingly positioned with the third positioning mark. When assembling the third noise reduction component 41, proper positioning is required; therefore, a third positioning mark is added to the top wall of the housing 10. When bonding the third noise reduction component 41, aligning one corner or one side of the third noise reduction component 41 with the third positioning mark completes the positioning operation of the third noise reduction component 41.

[0062] Optionally, the third positioning mark is a protruding structure protruding from the top wall surface of the chassis 10. The positioning and installation of the third noise reduction component 41 can be achieved by contacting or abutting one corner or one side of the protruding structure.

[0063] In this embodiment, a third adhesive layer is provided on the side of the third noise reduction component 41 facing the top wall for bonding with the top wall. The third adhesive layer has strong bonding performance and high resistance to heat attenuation. Since the temperature inside the server rises after a period of operation, the third adhesive layer ensures a firm bond between the third noise reduction component 41 and the top wall of the chassis 10, preventing the third noise reduction component 41 from detaching or shifting due to vibration during server operation, thereby ensuring the stability and long-term reliability of the third noise reduction component 41.

[0064] Specifically, the fourth noise reduction component 42 is provided with multiple third clearance grooves 420 at intervals along its extension direction. The shape of the third clearance grooves 420 projected onto the bottom wall is consistent with the shape of the protruding structure on the mounting assembly 20. This arrangement is necessary because, when designing the fourth noise reduction component 42, clearance from the protruding structure on the mounting bracket 21 must also be considered. To achieve this, the outline of the protruding structure on the mounting bracket 21 is projected onto the plane of the fourth noise reduction component 42 to obtain its projected outline on the fourth noise reduction component 42. Then, using laser cutting, the corresponding foam is cut away along the outline to form the third clearance grooves 420 for proper clearance. This not only protects the normal operation of the mounting bracket 21 but also improves the installation accuracy and reliability of the fourth noise reduction component 42.

[0065] In this embodiment, there is a preset distance h1 between the two sidewalls, and a preset distance h2 between the mounting component 20 and the cooling fan. The length a3 and width b3 of the third noise reduction component 41 satisfy a3 = h1 and b3 = h2, respectively. With the above settings, the length a3 and width b3 of the fourth noise reduction component 42 strictly follow the preset distance h1 between the two sidewalls and the preset distance h2 between the mounting component 20 and the cooling fan. This precise dimensional matching maximizes the use of the bottom wall space, ensures full coverage of the fourth noise reduction component, reduces unnecessary material usage, and optimizes costs.

[0066] In this embodiment, a fourth positioning mark is provided on the bottom wall, and at least a portion of the outer edge of the fourth noise reduction component 42 corresponds to the fourth positioning mark. When assembling the fourth noise reduction component 42, proper positioning is required; therefore, a fourth positioning mark is added to the bottom wall of the housing 10. When bonding the fourth noise reduction component 42, aligning one corner or one side of the fourth noise reduction component 42 with the fourth positioning mark completes the positioning operation of the fourth noise reduction component 42.

[0067] Optionally, the fourth positioning mark is a protruding structure protruding from the bottom wall surface of the chassis 10. The positioning and installation of the fourth noise reduction component 42 can be achieved by contacting or abutting one corner or one side of the protruding structure.

[0068] In this embodiment, a fourth adhesive layer is provided on the side of the fourth noise reduction component 42 facing the bottom wall for bonding to the bottom wall. The fourth adhesive layer has strong bonding performance and high resistance to heat attenuation. Since the temperature inside the server rises after a period of operation, the fourth adhesive layer ensures a firm bond between the fourth noise reduction component 42 and the bottom wall of the chassis 10, preventing the fourth noise reduction component 42 from detaching or shifting due to vibration during server operation, thereby ensuring the stability and long-term reliability of the fourth noise reduction component 42.

[0069] In this embodiment, there is a preset distance h3 between the mounting component 20 and the heat sink wall, and a preset distance h4 between the top wall and the bottom wall. The length a4 and width b3 of the fifth noise reduction component 43 satisfy: a4 = h3, b4 = h4. With the above settings, the length a4 and width b4 of the fifth noise reduction component 43 are equal to the preset distance h3 between the mounting component 20 and the heat sink wall, and the preset distance h4 between the top wall and the bottom wall, respectively. This precise dimensional design ensures that the fifth noise reduction component 43 can fully cover the target area, effectively isolating and reducing fan noise, while avoiding installation difficulties and material waste caused by excessive size.

[0070] In this embodiment, a fifth positioning mark is provided on the side wall, and at least a portion of the outer edge of the fifth noise reduction component 43 corresponds to the fifth positioning mark. When assembling the fifth noise reduction component 43, proper positioning is required; therefore, a fifth positioning mark is added to the side wall of the chassis 10. When bonding the fifth noise reduction component 43, aligning one corner or one side of the fifth noise reduction component 43 with the fifth positioning mark completes the positioning operation of the fifth noise reduction component 43.

[0071] Optionally, the fifth positioning mark is a protruding structure protruding from the side wall surface of the chassis 10. The fifth noise reduction component 43 can be positioned and installed by contacting or abutting one corner or one side of the protruding structure.

[0072] In this embodiment, a fifth adhesive layer is provided on the side of the fifth noise reduction component 43 facing the sidewall for bonding with the sidewall. The fifth adhesive layer has strong bonding performance and high resistance to heat attenuation. Since the temperature inside the server rises after a period of operation, the fifth adhesive layer ensures a firm bond between the fifth noise reduction component 43 and the sidewall of the chassis 10, preventing the fifth noise reduction component 43 from detaching or shifting due to vibration during server operation, thereby ensuring the stability and long-term reliability of the fifth noise reduction component 43.

[0073] In this application, both the first noise reduction component 30 and the second noise reduction component 40 are made of noise reduction foam.

[0074] This application also provides a server, including the aforementioned chassis assembly.

[0075] By precisely placing the first noise reduction component 30 and the second noise reduction component 40 at key locations within the server chassis, effective absorption and isolation of cooling fan noise are achieved, significantly reducing the impact of noise on the hard drive and other sensitive components, and improving the server's operational stability and data processing accuracy. Simultaneously, the first and second noise reduction components 30 and 40 are designed with the server's internal heat exchange requirements in mind, avoiding obstruction of the heat dissipation path, maintaining good airflow, which helps improve the server's thermal management performance, ensures that critical hardware components operate at suitable temperatures, and extends the server's lifespan.
