Description

Technical Field

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

[0002] The development of server hardware has been accompanied by the rise of AI technology, leading to an increasing demand for high strength and high reliability. In AI servers, the use of GPU accelerator cards (OAM) is becoming increasingly common. To effectively integrate multiple GPUs into a powerful matrix processing platform, substrates (such as UBBs) are typically used for connection and integration. To ensure the stability and security of the substrate within the server, a trade-off between cost and performance exists in the market regarding the selection of UBB backing plates. On the one hand, die-cast backing plates remain the preferred choice for many high-end servers due to their excellent physical properties and reliability; however, on the other hand, their high manufacturing cost and weight limit their widespread adoption in a wider range of applications.

[0003] Therefore, the substrate tray in the relevant technology cannot simultaneously achieve low production cost and high support strength, which has a significant impact on the economy and practicality of server hardware, and innovative technical solutions are urgently needed to overcome this challenge. Utility Model Content

[0004] This application provides a tray assembly and server to at least solve the problem that substrate trays in related technologies cannot simultaneously have low production costs and high support strength.

[0005] This application provides a pallet assembly, including: a first sheet metal part and a second sheet metal part, the second sheet metal part being located above at least a portion of the first sheet metal part, the second sheet metal part being provided with a clearance opening for clearance of a portion of a supported component; and a plurality of fasteners passing through the first sheet metal part and the second sheet metal part to connect the first sheet metal part and the second sheet metal part.

[0006] Furthermore, the first sheet metal part includes a first plate body and a plurality of first protrusions disposed on the first plate body, each of the first protrusions being provided with a first fastening hole; the second sheet metal part includes a second plate body and a plurality of second protrusions disposed on the second plate body, each of the second protrusions being provided with a second fastening hole; wherein, the plurality of first protrusions and the plurality of second protrusions are each provided with a plurality of fasteners corresponding to each other, and each fastener passes through the corresponding first fastening hole and the corresponding second fastening hole.

[0007] Furthermore, the first plate and the second plate are spaced apart; each first protrusion is located on the side of the first plate closer to the second plate; each second protrusion is located on the side of the second plate closer to the first plate; wherein each first protrusion abuts against the corresponding second protrusion.

[0008] Furthermore, the first sheet metal part is provided with a receiving groove and an opening communicating with the receiving groove, and at least a portion of the second sheet metal part is located in the receiving groove.

[0009] Furthermore, the first sheet metal part includes a plurality of flanges connected sequentially around the periphery of the first plate to jointly form a receiving groove and an opening; wherein, the second sheet metal part is spaced apart from the first plate.

[0010] Furthermore, the depth of the receiving groove is greater than the thickness of the second sheet metal part; and / or, both the first plate and the second plate are rectangular plates.

[0011] Furthermore, the first sheet metal part also includes a plurality of connecting studs, which are spaced apart on the side of the receiving groove near the second sheet metal part. One end of each connecting stud is connected to the bottom surface of the receiving groove, and the other end of each connecting stud passes through the second sheet metal part and is connected to the supported part.

[0012] Furthermore, the supported component includes a substrate, and the clearance opening includes a first clearance opening for clearing a portion of the substrate.

[0013] Furthermore, the thickness of the first sheet metal part is 0.8 mm to 2 mm; and / or, the thickness of the second sheet metal part is 0.8 mm to 2 mm; and / or, the fasteners include rivets.

[0014] This application also provides a server, including a chassis and the aforementioned tray assembly disposed within the chassis.

[0015] This application addresses the issue that the tray assembly comprises a first sheet metal part and a second sheet metal part, with the second sheet metal part positioned above at least a portion of the first sheet metal part. The second sheet metal part has a clearance opening for avoiding a portion of the supported component. Multiple fasteners pass through the first and second sheet metal parts to connect them. Therefore, this application's tray assembly, by separately providing a first sheet metal part and a second sheet metal part, connecting them with fasteners, and providing a clearance opening on the second sheet metal part to avoid the supported component, while the first sheet metal part does not have a clearance opening, solves the problem in related technologies where substrate trays cannot simultaneously achieve low production costs and high support strength. This achieves the technical effect of increasing the structural strength and stability of the tray assembly, ensuring good shape and positional stability under heavy loads and protecting the supported component, while also facilitating the manufacturing of the tray assembly and ensuring that supported components such as substrates can be securely installed on the tray assembly, preventing easy loosening even during server operation and vibration.

Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0044] 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.

[0045] like Figures 1 to 12 As shown, this application provides a pallet assembly, including: a first sheet metal part 1 and a second sheet metal part 2, the second sheet metal part 2 being located above at least a portion of the first sheet metal part 1, the second sheet metal part 2 being provided with a clearance opening 20 for clearance of a portion of a supported component; and a plurality of fasteners 3, the plurality of fasteners 3 being disposed on the first sheet metal part 1 and the second sheet metal part 2 to connect the first sheet metal part 1 and the second sheet metal part 2.

[0046] In this way, the tray assembly of this application, by respectively setting a first sheet metal part 1 and a second sheet metal part 2, and connecting the first sheet metal part 1 and the second sheet metal part 2 with fasteners 3, and setting a clearance opening 20 on the second sheet metal part 2 to avoid the supported component, while not setting a clearance opening on the first sheet metal part 1, not only increases the structural strength and stability of the tray assembly, so that the tray assembly maintains good shape and position stability when bearing heavy loads, and plays a protective role for the supported component, but also facilitates the processing and manufacturing of the tray assembly, ensuring that the supported component such as the substrate can be firmly installed on the tray assembly, and will not easily loosen even when the server is subjected to vibration during operation, thus solving the problem in the related technology that the substrate tray cannot simultaneously have low production cost and high support strength.

[0047] Specifically, the installation efficiency and load-bearing capacity of pallet assemblies can be improved by optimizing the type and installation location of fasteners. Through meticulous optimization of fastener type and installation location, we can significantly enhance the installation efficiency and load-bearing capacity of pallet assemblies. This strategy is based on a deep understanding of the structural mechanics and engineering design principles of pallet assemblies. First, the choice of fastener type is crucial. For example, using high-strength alloy rivets instead of ordinary materials can increase the shear and tensile strength of the connection points, thereby improving the overall load-bearing capacity of the pallet assembly. This optimization is particularly important under the dense hardware layout and high workload conditions inside servers. Second, rationally planning the installation location and density of fasteners can make the force distribution more even, avoiding structural deformation or damage caused by excessive local stress. For example, placing more fasteners in the critical stress areas of the pallet and reducing the number of fasteners at the edges or non-load-bearing parts with lower stress ensures the necessary structural strength while avoiding excessive material use, achieving a balance between lightweight and high strength.

[0048] Furthermore, optimizing the placement of fasteners, considering the server's internal hardware layout and airflow, can minimize the impact on heat dissipation channels and ensure good heat dissipation performance. This is especially important for servers using high-performance graphics processing units (GPUs) or central processing units (CPUs), as good heat dissipation is crucial for maintaining stable hardware operation. In addition, considering the installation direction and angle of fasteners can simplify the installation process and reduce installation errors or difficulties caused by improper placement. For example, using self-tapping screws or pre-embedded studs for fixing in a specific direction allows for quick positioning and tightening, greatly improving the installation speed and efficiency of the tray assembly. This also reduces the workload of on-site installation personnel, improves overall assembly quality, and enhances server production efficiency.

[0049] In summary, by comprehensively optimizing the type, location, density, and installation direction of fasteners, we can significantly improve the installation efficiency of the tray assembly, enhance its load-bearing and fixing capabilities, and at the same time, take into account heat dissipation and lightweight design, ensuring the stable operation and long-term reliability of the internal components of the server. This is an important aspect of the technical solution of this application, which aims to create a more efficient, reliable, and economical server hardware support system.

[0050] Furthermore, the first sheet metal part 1 includes a first plate 11 and a plurality of first protrusions 12 disposed on the first plate 11, each of the first protrusions 12 being provided with a first fastening hole; the second sheet metal part 2 includes a second plate 21 and a plurality of second protrusions 22 disposed on the second plate 21, each of the second protrusions 22 being provided with a second fastening hole; wherein, the plurality of first protrusions 12 and the plurality of second protrusions 22 are respectively provided with a plurality of fasteners 3 in a one-to-one correspondence, and each fastener 3 is inserted through the corresponding first fastening hole and the corresponding second fastening hole.

[0051] In the tray assembly of this application, by providing protrusions and fastening holes on the first sheet metal part 1 and the second sheet metal part 2, and connecting them with fasteners 3, the structural strength and stability of the tray assembly are increased. This allows the tray assembly to maintain good shape and positional stability when subjected to heavy loads, ensuring that the baseboard and graphics processor accelerator card (OAM) can be firmly installed on the tray assembly and will not easily loosen even when encountering vibrations during server operation.

[0052] Furthermore, the first plate 11 and the second plate 21 are spaced apart; each first protrusion 12 is located on the side of the first plate 11 closest to the second plate 21; each second protrusion 22 is located on the side of the second plate 21 closest to the first plate 11; wherein each first protrusion 12 abuts against the corresponding second protrusion 22.

[0053] In the tray assembly of this application, the spacing between the first plate 11 and the second plate 21, and the alignment and abutment between the first protrusion 12 and the second protrusion 22, ensure physical contact and tight connection between the first sheet metal part 1 and the second sheet metal part 2, improving the structural rigidity of the entire tray assembly. Combined with the fasteners 3, this forms a robust tray assembly structure, achieving better load-bearing capacity and seismic resistance, making the installation of the base plate more reliable during server operation.

[0054] Specifically, the distance between the first plate 11 and the second plate 21 can be adjusted by adjusting the height of the first protrusion 12 and the second protrusion 22, thereby changing the thickness of the tray assembly to adapt to different server chassis; the outer dimensions of the first sheet metal part 1 can be the same as the outer dimensions of the corresponding substrate, or it can be slightly larger than the outer dimensions of the corresponding substrate.

[0055] In this way, by precisely adjusting the heights of the first protrusion 12 and the second protrusion 22, the spacing between the first plate 11 and the second plate 21 can be effectively adjusted, thereby flexibly changing the overall thickness of the tray assembly. This provides great convenience for adapting to diverse server chassis sizes and internal layouts, demonstrating the high adaptability and flexibility of the tray assembly in practical applications.

[0056] Server chassis designs vary significantly depending on brand, model, and application scenario. Some chassis have spacious internal spaces, suitable for installing thicker tray assemblies to enhance structural stability; while others, in order to save space, have a compact internal layout, requiring tray assemblies to be as thin as possible to reduce the space occupied. Therefore, sheet metal tray assemblies whose thickness can be adjusted by setting the first protrusion 12 and the second protrusion 22 are particularly crucial.

[0057] By adjusting the height of the first protrusion 12 and the second protrusion 22, the thickness of the tray assembly can be varied within a certain range. This allows the same tray assembly to flexibly adapt to server chassis with different thicknesses, whether it's a standard rack server, a highly optimized blade server, or a high-density server cluster, providing a suitable installation solution. This design not only reduces the variety of tray assembly inventory and production costs but also greatly simplifies the server maintenance and upgrade process, improving efficiency and convenience for users during hardware deployment.

[0058] While adjusting the thickness of the tray, it is also necessary to ensure that its structural strength and stability are not affected. This requires that the design of the first plate 11 and the second plate 21 at different spacings must take into account the strength characteristics of the materials, the rigidity of the raised structure, and the overall mechanical design principles, so as to ensure that no matter how the thickness of the tray assembly changes, it can withstand the weight of the internal components of the server and the impact force during operation, and maintain its due load-bearing capacity and fixing effect.

[0059] In summary, adjusting the height of the first protrusion 12 and the second protrusion 22 to change the thickness of the tray assembly is an important design strategy aimed at improving the versatility and adaptability of the tray assembly. It not only meets the installation requirements of server hardware in different chassis environments but also takes into account the electrical performance and structural stability of the server, opening up a wide range of applications for the tray assembly and making it an ideal choice for supporting and securing internal server components.

[0060] Furthermore, the first sheet metal part 1 is provided with a receiving groove 10 and an opening 15 communicating with the receiving groove 10, and at least a portion of the second sheet metal part 2 is located in the receiving groove 10.

[0061] In the pallet assembly of this application, the arrangement of the receiving groove 10 and the opening 15 provides installation space for the second sheet metal part 2, which helps the first sheet metal part 1 and the second sheet metal part 2 to form a compact and stable double-layer structure, achieving better space utilization and structural strength, so that the pallet assembly can provide sufficient support in a limited space.

[0062] Furthermore, the size of the opening 15 can be adjusted to accommodate substrates of different sizes while ensuring sufficient strength and stability.

[0063] Furthermore, the first sheet metal part 1 includes a first plate body 11 and a plurality of flanges 14 connected sequentially around the periphery of the first plate body 11 to jointly form a receiving groove 10 and an opening 15; wherein, the second sheet metal part 2 is spaced apart from the first plate body 11.

[0064] In the pallet assembly of this application, the flange 14 increases the edge strength of the first sheet metal part 1 and forms a receiving groove 10 with the first plate 11, providing an embedding space for the second sheet metal part 2 and also providing additional protection for the second sheet metal part 2, achieving better structural stability and load-bearing capacity, so that the pallet assembly can better resist external impacts and vibrations inside the server.

[0065] In addition, the structural strength of the pallet assembly can be further enhanced by changing the height of the flange.

[0066] Furthermore, the second sheet metal part 2 includes a second plate body 21; wherein the depth of the receiving groove 10 is greater than the thickness of the second sheet metal part 2; and / or, both the first plate body 11 and the second plate body 21 are rectangular plates.

[0067] In the pallet assembly of this application, the depth setting of the receiving groove 10 ensures that the second sheet metal part 2 can be fully embedded, which improves the overall structural stability of the pallet assembly. The rectangular plate design simplifies the manufacturing process of the pallet assembly, while providing sufficient area to support the substrate, achieving better structural matching and cost control, making the pallet assembly both economical and efficient to use.

[0068] Furthermore, the first sheet metal part 1 also includes a plurality of connecting studs 16, which are spaced apart on the side of the receiving groove 10 near the second sheet metal part 2. One end of each connecting stud 16 is connected to the bottom surface of the receiving groove 10, and the other end of each connecting stud 16 passes through the second sheet metal part 2 and is connected to the supported part.

[0069] In the tray assembly of this application, the connecting studs 16 provide a direct means of fixing to the substrate and the graphics processing unit accelerator card (OAM). In principle, connecting the first sheet metal part 1 to the substrate and the graphics processing unit accelerator card (OAM) via the studs achieves reliable fixing and electrical connection, facilitates easier installation and removal, and ensures stable operation of the substrate and the graphics processing unit accelerator card (OAM).

[0070] The plurality of connecting studs 16 include a first stud 161 for connection to the substrate; the plurality of connecting studs 16 include a second stud 162 for connection to the graphics processor accelerator card (OAM).

[0071] In the sheet metal tray assembly of this application, the design of multiple connecting studs 16 is one of the core elements that ensures the tray can stably support and fix the substrate and the graphics processing accelerator card (OAM). These connecting studs not only play a bridging role structurally, tightly integrating the substrate and graphics processing accelerator card (OAM) with the tray assembly, but also functionally facilitate the establishment of electrical connections between components, providing a physical basis for high-speed data exchange.

[0072] The first stud 161 is a connection point for the substrate. Given that the substrate often houses multiple high-performance GPUs and requires high-speed data interaction with the CPU and other internal server components, the position and number of the first studs 161 must be carefully planned to ensure the substrate can be accurately mounted on the tray assembly and maintain sufficient stability and firmness even during vibrations. To achieve this, the first studs 161 are typically distributed at the four corners of the substrate and around it to evenly distribute the load and improve fixing accuracy. Furthermore, considering the substrate's electrical interfaces, the position of the first studs 161 must also avoid these critical areas to ensure that the normal operation of the electrical and heat dissipation systems is not affected.

[0073] The design of the second stud 162 focuses on the installation and fixation of the graphics processing accelerator card (OAM), aiming to meet the connection requirements between the OAM and the substrate, as well as other server components. As a highly standardized and modular GPU component, the OAM may require more flexible installation positions and angles to adapt to the space constraints and layout requirements within different servers. Therefore, the position and number of the second studs 162 need to be determined based on the layout of the OAM on the substrate and the fixation requirements of the OAM itself. To ensure precise mating of the OAM and stability in high-load computing environments, the second studs 162 may be distributed at the fixing points of the OAM, such as the center, corners, or edges, to provide sufficient fixing force and prevent loosening.

[0074] In summary, the design of the multiple connecting studs 16 in the sheet metal tray assembly of this application, including the first stud 161 and the second stud 162, is not only the foundation for physical fixing but also crucial for the electrical connection strategy. Their layout, quantity, and design details directly affect the installation efficiency, operational stability, and overall system performance of the server's internal components. Through refined stud design, we can maximize the server's compatibility and functionality within a limited space, providing solid support for building high-performance, highly reliable AI servers.

[0075] Specifically, the substrate is a substrate that can be equipped with a graphics processing unit (GPU) module. By equipping the GPU, a complete GPU platform is formed, enabling direct connection with the graphics processing accelerator card (OAM). This provides a channel that allows for high-speed data transmission and exchange, facilitating the collaborative work of multiple GPUs to handle computationally intensive tasks in AI fields such as image recognition and machine learning.

[0076] In some embodiments, the substrate can provide power management and heat dissipation support for GPUs and other components, ensuring the stable operation of related modules.

[0077] In some embodiments, the substrate is a UBB that can support multiple graphics processors operating in various wiring and interconnect topologies, such as using eight graphics processor accelerator cards (OAM).

[0078] The unit base board (UBB) integrates multiple GPUs into a matrix platform, providing high-speed data exchange capabilities between GPUs and between GPUs and the CPU. The Open Accelerator Card (OAM) is a GPU module designed based on the Open Accelerator Module (OPC) standard and can be inserted into the UBB. Furthermore, the supported component includes the baseboard, and the clearance opening 20 includes a first clearance opening 201 for clearing the baseboard. The first sheet metal part 1 has no openings to protect the supported component.

[0079] In the tray assembly of this application, the design of the first clearance opening 201 ensures the compatibility of the tray assembly with the bottom surface devices of the substrate, avoids conflicts with the bottom surface devices of the substrate, ensures the normal operation of the bottom surface devices of the substrate, and achieves better equipment compatibility and maintenance convenience.

[0080] In particular, by setting more types of clearance openings 20, it is possible to adapt to different types of substrates, thereby ensuring the wide applicability of the tray assembly.

[0081] By incorporating different types of clearance openings 20 when designing tray assemblies, the flexibility and versatility of the assembly can be significantly enhanced, enabling it to adapt to substrates of various models, sizes, and layouts. Specifically, different substrate models may have different bottom surface features, including but not limited to heat sinks, connectors, and cable outlets, the location and size of which may vary significantly between different substrates. Therefore, the clearance openings 20 on the tray assembly need to be customized to address these features to ensure that the substrate can be mounted on the tray without obstruction while maintaining sufficient mechanical strength and stability.

[0082] To achieve this goal, the following settings can be used:

[0083] Customized opening positions: By comparing in detail with the substrate manufacturer or design drawings, the key feature positions on the bottom surface of the substrate are accurately measured and recorded. Then, during the tray assembly design stage, avoidance openings 20 are opened in appropriate positions based on these data to ensure that the openings are aligned with the features of the substrate and avoid interference.

[0084] Diverse opening sizes: In addition to precise positioning, the size of the clearance opening 20 also needs to be adjusted according to the size of the substrate bottom surface features. For example, for larger devices, larger openings are required to ensure sufficient space; while for small connectors or lines, smaller openings or slots can be designed to maintain the integrity of the tray assembly while avoiding interference.

[0085] Opening shape optimization: The shape of the avoidance opening 20 is not limited to a simple circle or square. Designers can optimize the opening according to the specific shape of the substrate bottom surface features, such as using elliptical, rectangular, polygonal or irregular shaped openings, to better adapt to the shape of the features, reduce unnecessary material waste, and maintain the structural strength of the tray assembly.

[0086] Dynamic adjustment of opening layout: Considering possible changes in future substrate models and designs, the tray assembly can be designed with a modular or adjustable layout. For example, the clearance opening 20 can be designed to be removable or shielded, so that when a new substrate model needs to be adapted, only the second sheet metal part 2 needs to be replaced or adjusted, without redesigning and manufacturing the entire tray assembly.

[0087] By implementing the above strategies, the tray assembly can not only seamlessly adapt to various types of substrates, but also provide flexible installation solutions without sacrificing structural strength and stability. This helps improve the assembly efficiency and operational reliability of servers, while also leaving room for future technological iterations and upgrades, thereby enhancing the product's market competitiveness and user satisfaction.

[0088] Furthermore, the thickness of the first sheet metal part 1 is 0.8 mm to 2 mm; and / or, the thickness of the second sheet metal part 2 is 0.8 mm to 2 mm; and / or, the fastener 3 includes rivets.

[0089] Specifically, the thickness of the first sheet metal part 1 and the second sheet metal part 2 is 1.2mm, which is of great significance for ensuring the structural strength, weight control and cost-effectiveness of the pallet assembly.

[0090] First, from the perspective of structural strength, the 1.2mm thickness provides sufficient rigidity for the first sheet metal part 1 and the second sheet metal part 2, enabling the tray assembly to withstand the weight of the server's internal hardware. Especially when carrying the baseboard and graphics processor accelerator card (OAM), it can effectively resist deformation caused by heavy load or vibration, ensuring the stability and positioning accuracy of the hardware.

[0091] Secondly, from a weight control perspective, the 1.2mm sheet metal thickness ensures the structural strength of both the first sheet metal part 1 and the second sheet metal part 2 while minimizing the weight of the tray assembly. This is particularly important for server design, as lightweight design not only reduces overall server energy consumption—lighter components mean lower drive energy consumption—but also facilitates server transportation and installation, reducing the difficulty and potential risks during physical handling. Furthermore, lightweight design helps improve the server's thermal management efficiency, reducing the pressure on the cooling system.

[0092] Furthermore, considering cost-effectiveness, a thickness of 1.2mm is economically reasonable under current sheet metal processing technology. Sheet metal that is too thin may be prone to bending or damage during production, leading to a lower yield rate and additional repair processes. On the other hand, excessively thick sheet metal increases raw material consumption and processing difficulty, raising manufacturing costs. A sheet metal thickness of 1.2mm ensures both ease of processing of the first sheet metal part 1 and the second sheet metal part 2, as well as the quality of the finished product, while controlling material costs, achieving the best cost-performance ratio.

[0093] Finally, from a compatibility and adaptability perspective, the 1.2mm sheet metal thickness allows for a good match between the first sheet metal part 1 and the second sheet metal part 2 and existing server internal structures and fastener standards. Sheet metal parts of this thickness are widely used in industrial design, making it easy to find compliant processing equipment and fasteners. It also facilitates co-design with other structural components, ensuring the tray assembly can be smoothly embedded into the server chassis. This supports the installation of different models and configurations of circuit boards and graphics processing unit accelerator cards (OAM), enhancing the product's market adaptability and user experience satisfaction.

[0094] In summary, setting the thickness of the first sheet metal part 1 and the second sheet metal part 2 to 1.2mm is the result of seeking the optimal solution in terms of structural strength, weight management, cost control and compatibility. It not only directly affects the physical performance of the tray assembly, but also relates to the overall performance and economic practicality of the server.

[0095] When fastener 3 specifically refers to a rivet, this technical solution demonstrates unique technical effects and advantages. As a mature and widely used fastening method, rivets, with their excellent connection strength and reliable fixing performance, are an ideal choice to ensure a stable connection between the first sheet metal part 1 and the second sheet metal part 2. This is achieved through the first fastener on the first protrusion 12 of the first sheet metal part 1 and the second protrusion 22 of the second sheet metal part 2 within the internal structure of the server. Furthermore, the rivet connection provides excellent vibration resistance, maintaining the structural integrity of the pallet assembly even under high-load operating environments, preventing component loosening or damage caused by vibration, thereby ensuring the stability and reliability of the server. More importantly, the permanent nature of the rivet connection means that once the connection is complete, it will not gradually loosen over time like screws, which greatly extends the service life of the pallet assembly and reduces maintenance frequency. Therefore, the use of rivets as fastener 3 enhances the mechanical stability and long-term operational reliability of the entire pallet assembly.

[0096] This application also provides a server, including a chassis and the aforementioned tray assembly disposed within the chassis.

[0097] The server described in this application uses the aforementioned tray assembly, which significantly improves the structural strength and cost-effectiveness of the server's internal chassis. It can more effectively support and manage the baseboard and graphics processor accelerator card (OAM), while reducing the server's production cost. This results in improved server performance and reduced maintenance costs, enabling the server to exhibit better stability and efficiency in artificial intelligence (AI) computing tasks.

[0098] In addition to optimizing fastener types and mounting locations to enhance the mechanical performance of the tray assembly, we can further improve the overall performance and reliability of the server by integrating efficient heat dissipation structures onto the tray assembly. This is especially true in AI servers, where the intensive use of high-performance processors such as GPUs and CPUs generates enormous amounts of heat; therefore, a good heat dissipation design is a key factor in ensuring stable server operation and extending hardware lifespan.

[0099] Specifically, the heat dissipation structure on the tray assembly can take several forms:

[0100] Heat sinks: Add heat sinks to appropriate locations on the tray assembly, especially for components that are in direct or indirect contact with heat sources. Heat sinks facilitate heat transfer by increasing surface area, guiding heat from inside the server to the casing, and then dissipating it through an external cooling system.

[0101] Thermal pads: Thermal pads are added between the tray assembly and key heat-generating components to improve heat transfer efficiency. These pads have good compressibility and elasticity, allowing them to fill the tiny gaps between the heat source and the heat dissipation structure, reducing thermal resistance and accelerating heat dissipation.

[0102] Airflow channels: When designing the tray assembly, consider creating or forming airflow channels on the first and second sheet metal parts. This helps guide cool air through the heat source areas inside the server, thereby improving cooling efficiency. This design is particularly suitable for servers requiring forced air cooling, as it can significantly improve airflow organization and reduce the risk of localized overheating.

[0103] Heat pipes: Heat pipes are embedded in or closely fitted to a tray assembly, utilizing the phase change process of the liquid inside the heat pipe to efficiently transfer heat. Heat pipes can achieve high heat transfer rates at relatively low temperature gradients, making them ideal for applications requiring rapid heat dissipation.

[0104] Liquid cooling pipes: For servers under extreme loads, liquid cooling pipes can be integrated into the tray assembly to remove a large amount of heat through liquid circulation. Although liquid cooling systems are complex, their heat dissipation efficiency is far superior to air cooling, effectively handling the heat load generated by high-power hardware.

[0105] Through the integration of the aforementioned heat dissipation structures, the tray assembly not only provides physical support and fixation but also becomes a crucial component of the server's internal thermal management. During the design process, the server's heat source distribution and airflow paths should be carefully analyzed, and heat dissipation components should be added strategically near the heat sources while ensuring the overall heat dissipation system is balanced and efficient. The optimized heat dissipation structure not only helps to quickly dissipate heat and prevent the formation of hot spots but also reduces noise levels and improves the server's energy efficiency. This comprehensively enhances the server's overall performance and reliability across multiple dimensions, providing a strong guarantee for the server's continuous and stable operation.
