Description

Technical Field

[0001] This application relates to the field of server technology, and in particular to a server node shell and a server node having the same. Background Technology

[0002] Currently, in the field of multi-node servers, the shell of traditional computing nodes mainly consists of a metal top cover and a plastic air guide. The metal top cover is used to provide structural support and ensure the rigidity and stability of the computing node under various physical conditions, while the air guide serves as an airflow guiding structural component.

[0003] However, the separate design of the air guide cover and the top cover in the relevant technology means that two independent installation operations are required in the node assembly process: first, the air guide cover is fixed to the internal node, and then the top cover is fastened to the top of the node. For the mass production of multi-node servers, the additional assembly steps for each node will prolong the overall production time, reduce production line efficiency, and may also increase the risk of dimensional tolerance accumulation due to multiple assembly operations.

[0063] 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.

[0064] To address the problem of low assembly and disassembly efficiency of computing node housings in related technologies, this application provides a server node housing and a server node having the same.

[0065] Example 1

[0066] like Figures 1 to 17 , Figures 22 to 24As shown, the server node housing includes a base 10 and an air guide assembly. The air guide assembly includes a first bracket 20, a second bracket 30, an air guide 40, and a locking assembly 50. The first bracket 20 and the second bracket 30 are spaced apart on the air guide 40. One of the first bracket 20 and the second bracket 30 is rotatably connected to the base 10. The locking assembly 50 is disposed on the other of the first bracket 20 and the second bracket 30. The locking assembly 50 includes a movable locking structure 51, which has a locked position where the locking structure 51 retracts to a locking position that engages with the base 10, and an unlocked position where the locking structure 51 extends out of the base 10.

[0067] Applying the technical solution of this embodiment, the air guide shroud assembly integrates the first bracket 20 and the second bracket 30, replacing the design of separate installation of the top cover and air guide shroud in related technologies, thus achieving structural integration. This reduces installation steps, solves the problem of low disassembly and assembly efficiency of the computing node housing in related technologies, improves production efficiency, and also reduces dimensional tolerances accumulated from multiple assemblies, improving the overall structural accuracy and stability of the node. Simultaneously, the rotatable connection design between the first bracket 20 and the base 10, combined with the movable locking structure 51 of the locking component 50, provides a rotary installation and tool-free disassembly solution, making the installation and disassembly of the air guide shroud assembly more convenient and achievable without specialized tools. This significantly improves maintenance and upgrade efficiency while reducing operational difficulty and time costs.

[0068] like Figure 1 , Figure 3 as well as Figures 5 to 7 As shown, the server node housing also includes a front window 60, which is mounted on the base 10. The surface of the air guide shroud 40 facing the base 10 is a mounting surface 41. The first bracket 20 and the second bracket 30 are both mounted on the mounting surface 41, with the first bracket 20 positioned closer to the front window 60 than the second bracket 30. By mounting the front window 60 on the base 10, it is ensured that cool air enters the server directly and efficiently, providing priority cooling for critical components such as the CPU and memory. Simultaneously, the surface of the air guide shroud 40 facing the base 10 is the mounting surface 41, on which both the first bracket 20 and the second bracket 30 are mounted, with the first bracket 20 positioned closer to the front window 60. This arrangement ensures a more stable installation of the air guide shroud assembly within the node housing.

[0069] In this embodiment, the first bracket 20 is closer to the cold air inlet (i.e., the front window 60), ensuring that the air guide shroud 40 does not obstruct normal ventilation of the front window when it is rotated open. Simultaneously, when closed, it better guides the cold airflow towards high heat density areas, such as the CPU and memory near the front window. Thus, this design not only improves thermal management efficiency but also ensures uniform airflow distribution within the node, thereby enhancing the overall heat dissipation performance and operational stability of the server.

[0070] like Figure 8 As shown, the base 10 has a first mounting groove 11, which includes a first mounting groove segment 111 and a first snap-fit ​​groove segment 112 that are interconnected. The width of the first snap-fit ​​groove segment 112 is smaller than the width of the first mounting groove segment 111. The first bracket 20 includes a first body 21 and a first protrusion 22. The first body 21 is connected to the air guide shroud 40. The first protrusion 22 is disposed on the first body 21. The first bracket 20 is rotatably mounted on the base 10 by sliding the first protrusion 22 through the first mounting groove segment 111 until it engages with the first snap-fit ​​groove segment 112. Thus, through the engagement of the first mounting groove segment 111 and the first snap-fit ​​groove segment 112, the first protrusion 22 can slide smoothly in the first mounting groove segment 111 and then precisely snap into the first snap-fit ​​groove segment 112, achieving rotatable mounting of the first bracket 20 on the base 10. Shanghai Su Design ensured the stability of the first bracket 20 installation. At the same time, the reduced width of the first card slot section 112 further enhanced the compactness of the structure, effectively utilized the internal space of the server node housing, reduced the overall size and weight of the node, and facilitated the lightweight design of the server.

[0071] Specifically, the aforementioned configuration of the first mounting slot 11 enables a sliding and snap-fit ​​connection between the base 10 and the first bracket 20, eliminating the need for complex installation tools and significantly simplifying the assembly process of the server node housing. Simultaneously, when maintenance or inspection of the node's internal components is required, the first bracket 20 can be easily removed from the first snap-fit ​​slot 112 for quick disassembly, improving the convenience of server maintenance and upgrades, reducing downtime, and ultimately enhancing the overall availability and operational efficiency of the server.

[0072] like Figure 11As shown, the first body 21 includes a first plate 211, a second plate 212, and a third plate 213, which are bent sequentially. The first plate 211 and the third plate 213 are arranged opposite to each other, and the second plate 212 is connected to the air guide shroud 40. A first protrusion 22 is provided on the first plate 211 and / or the third plate 213. Thus, the first body 21, through the sequential bending of the first plate 211, the second plate 212, and the third plate 213, forms a U-shaped structure, thereby improving the structural strength and rigidity of the first support 20. This effectively prevents deformation caused by vibration of internal components or external impact during server operation, ensuring the long-term stability and reliability of the server node housing.

[0073] In this embodiment, the first protrusion 22 is disposed on the first plate 211 and the third plate 213, which not only makes the installation between the first bracket 20 and the base 10 more stable, but also ensures that the first protrusion 22 is easy to position during operation. When the first bracket 20 needs to be installed or removed, the operator can directly identify the position of the first protrusion 22 and, through cooperation with the first mounting groove 11 on the base 10, quickly and accurately complete the rotation installation or removal action, which greatly improves the efficiency of maintenance and assembly.

[0074] like Figure 22 and Figure 23 As shown, the locking assembly 50 also includes a sleeve 52, which is disposed on the second bracket 30. The locking structure 51 is telescopically inserted into the sleeve 52. The locking structure 51 includes an operating part 511, a connecting post 512, and a conical part 513 connected in sequence. Along the direction from the operating part 511 to the conical part 513, the outer diameter of the conical part 513 gradually increases. The conical surface of the conical part 513 facing the operating part 511 forms a first mating surface 5131. When the locking assembly 50 is in the locked position, at least a portion of the first mating surface 5131 abuts against the base 10, thereby limiting the engagement between the locking structure 51 and the base 10. Thus, the aforementioned arrangement of the conical part 513 enables it to form a stable limiting engagement with the base 10 during telescopic movement. When locked, the first mating surface 5131 of the conical portion 513 contacts the base 10. Since the outer diameter of the conical portion 513 gradually increases from the operating part 511 to the conical portion 513, the first mating surface 5131 can provide sufficient friction and support. Even if the server is subjected to vibration during high-load operation or physical movement, the air guide assembly can remain stable and is less prone to accidental unlocking or displacement. Therefore, the above-mentioned configuration of the locking structure 51 ensures the stability of the internal structure of the server node housing, improving the overall operating efficiency and security of the server.

[0075] Optionally, the operating part 511 of the locking structure 51 is designed in a form that is easy to operate by hand, such as a knob or push rod, so that the operator can extend and retract the locking structure 51 manually without the need for any tools, thereby completing the locking and unlocking of the air guide shroud assembly. In this way, the above-mentioned settings greatly simplify the daily operation and maintenance of the server node housing and improve the work efficiency of maintenance personnel.

[0076] like Figure 2 , Figure 4 as well as Figure 24 As shown, the base 10 has a mounting recess, which includes a first mounting opening 12, a second mounting opening 13, and a second mating surface 14. The second mating surface 14 is located between the first mounting opening 12 and the second mounting opening 13. The size of the first mounting opening 12 is larger than the size of the second mounting opening 13. When the connecting post 512 passes through the second mounting opening 13 and the locking assembly 50 is in the locked position, at least a portion of the first mating surface 5131 abuts against the second mating surface 14, and the conical portion 513 blocks the first mounting opening 12. In this way, when locked, the connecting post 512 is inserted into the smaller second mounting port 13, and at this time, the large-diameter end of the conical part 513 (i.e., at least part of the first mating surface 5131) is tightly fitted with the second mating surface 14, forming a mechanical block and limit. This not only ensures a firm connection between the locking structure 51 and the base 10, but also prevents the locking structure 51 from accidentally dislodging from the second mounting port 13 under external impact or vibration by blocking the first mounting port 12 through the conical part 513. This ensures the stability and safety of the air guide shroud assembly in the entire server node housing.

[0077] Specifically, the larger size of the first mounting port 12 allows the locking structure 51 to be easily removed from the mounting recess in the unlocked state, facilitating maintenance and repair. In the locked state, the conical portion 513 obscures the first mounting port 12, resulting in a cleaner overall appearance of the mounting recess, with no obvious installation marks, thus improving the aesthetics and space utilization of the server node housing. Simultaneously, this design avoids unnecessary misoperation during maintenance, improving operational accuracy and safety.

[0078] Optionally, the locking assembly 50 also includes an elastic structure. This elastic structure is connected to the locking structure 51 to apply an elastic force to the conical portion 513, abutting against the base 10. This elastic structure enables the locking assembly 50 to have an automatic locking function. When the operator aligns the connecting post 512 with the second mounting port 13 and applies a downward force, the conical portion 513 automatically forms a tight abutment with the second mating surface 14 of the base 10 under the action of the elastic force, achieving a locked state without additional operation. Simultaneously, the elastic force of the elastic structure abuts against the base 10 when the locking assembly is in the locked position. When unlocking is required, the operator only needs to overcome the reaction force of the elastic structure and push the operating part 511 to retract or move the conical portion 513 out of the second mounting port 13 to achieve unlocking. This design makes the unlocking process smoother, reduces the force required by maintenance personnel during unlocking, avoids component damage caused by excessive force or improper direction, thereby reducing the difficulty and risk of server maintenance and improving maintenance efficiency.

[0079] Optionally, the elastic structure is a spring.

[0080] like Figures 1 to 4 As shown, the base 10 has a second mounting groove 15, and the second bracket 30 includes a second body 31 and a second protrusion 32. The second body 31 is connected to the air guide shroud 40, and the second protrusion 32 is disposed on the second body 31. The second protrusion 32 extends into the second mounting groove 15 and engages with it to connect the second bracket 30 and the base 10. In this way, the second protrusion 32 extends into the second mounting groove 15 of the base 10, and through this limiting engagement, the second bracket 30 is stably connected to the base 10. This not only enhances the structural stability and rigidity after assembly but also effectively resists vibration and impact in the server's working environment by reinforcing the connection point between the bracket and the base, ensuring the structural integrity of the server node housing under high-intensity operating conditions.

[0081] In this embodiment, the limiting fit design between the second protrusion 32 and the second mounting groove 15 ensures the precise positioning of the second bracket 30 during installation. This not only reduces assembly errors and improves the manufacturing and assembly precision of the server node housing, but also enables maintenance personnel to quickly identify and correctly operate the installation and disassembly of the second bracket 30 during inspection or maintenance, without the need for cumbersome tools and complicated operating procedures.

[0082] like Figures 1 to 6As shown, the base 10 includes a base body 16, which has a mounting cavity. At least a portion of the base body 16 protrudes towards the mounting cavity to form a first mounting portion, and a first mounting groove 11 is disposed on the first mounting portion. At least another portion of the base body 16 protrudes towards the mounting cavity to form a second mounting portion 18, and a second mounting groove 15 and a second mounting opening 13 are both disposed on the second mounting portion 18. A mounting plate 17 is disposed on the second mounting portion 18, and the surface of the mounting plate 17 fits against the second mounting portion 18. The mounting plate 17 has a first mounting opening 12, and a portion of the second mounting portion 18 opposite to the first mounting opening 12 forms a second mating surface 14. Thus, the base body 16, through the first mounting portion and the second mounting portion 18 protruding towards the mounting cavity, provides a more stable connection foundation for the air guide shroud 40 and the locking assembly 50. Meanwhile, the first mounting slot 11 and the second mounting slot 15 are respectively provided on the first mounting part and the second mounting part 18, so that the front and rear brackets can be accurately connected to the base 10. This not only improves the strength of the connection part, but also enhances the structural stability of the entire server node shell, effectively resisting vibration and impact during operation.

[0083] In this embodiment, by providing a mounting plate 17 on the second mounting portion 18, opening a first mounting port 12 on the mounting plate 17, and forming a second mating surface 14 on the second mounting portion 18 opposite to the first mounting port 12, the spatial layout provides an optimized path for the installation of the air guide shroud 40 and the guidance of cold air. When the locking component 50 is in the locked position, the cone-shaped portion 513 blocks the first mounting port 12, ensuring that cold air can flow precisely to the high heat density device areas inside the server, such as the CPU and memory modules, through the preset air duct structure. This improves heat dissipation efficiency, reduces the operating temperature of the server, and extends the service life of the server, which has a significant effect on improving the energy efficiency and operational stability of the data center.

[0084] like Figure 2 and Figure 4As shown, the second mounting groove 15 includes a second mounting groove section 151 and a second snap-fit ​​groove section 152 that are interconnected. The width of the second mounting groove section 151 is greater than the width of the second snap-fit ​​groove section 152. The second bracket 30 is mounted on the base 10 by sliding the second protrusion 32 through the second mounting groove section 151 to engage with the second snap-fit ​​groove section 152. The width of the second mounting groove section 151 gradually decreases along the direction from the second mounting groove section 151 to the second snap-fit ​​groove section 152. This groove width design of the second mounting groove 15 allows the second protrusion 32 to easily slide into the wider second mounting groove section 151, and then, as the second protrusion 32 continues to advance, the groove width gradually decreases until it engages with the narrower second snap-fit ​​groove section 152. Simultaneously, this gradually decreasing groove width design not only simplifies the assembly process of the second bracket 30 and the base 10 but also speeds up the assembly process. The operator can complete the installation without precise alignment, significantly improving the assembly efficiency of the production line.

[0085] Specifically, the gradual width transition between the second mounting slot 151 and the second snap-fit ​​slot 152 ensures that the second protrusion 32 forms a secure mechanical snap-fit ​​when sliding into the second snap-fit ​​slot 152, effectively preventing the bracket from loosening or falling off due to vibration or external impact during server operation. Simultaneously, the narrower width of the second snap-fit ​​slot 152 provides stronger limiting, maintaining a stable connection between the second bracket 30 and the base 10 even under prolonged high-load server operation, providing continuous support and protection for internal server components, and improving the overall reliability and operational stability of the server.

[0086] like Figures 10 to 14 As shown, the air guide shroud 40 includes a shroud body 42, an air guide plate 43, and a flow guide section 44. The shroud body 42 is connected to both the first support 20 and the second support 30, and has a mounting surface 41. The air guide plate 43 is disposed on the mounting surface 41, located between the first support 20 and the second support 30, forming an airflow area around the inner surface of the base 10. The flow guide section 44 is disposed on the mounting surface 41, and its surface facing away from the mounting surface 41 forms a guide surface 441. Thus, the shroud body 42 of the air guide shroud 40 is connected to the first support 20 and the second support 30. Through the arrangement of the air guide plate 43 and the flow guide section 44, an effective airflow channel can be formed inside the server node housing. The air guide plate 43 and the inner surface of the base 10 together form the airflow area, ensuring that cool air can flow directly and efficiently to high heat density areas, such as the CPU and memory modules, thereby significantly improving heat dissipation efficiency. Meanwhile, the air guide surface 441 further optimizes the airflow guidance path, which can maintain good cooling effect for internal components of the server even under high load conditions, extend hardware life, and improve the server's operational stability and energy efficiency.

[0087] In this embodiment, the cover body 42 is connected to the first bracket 20 and the second bracket 30, which not only enhances the overall structural stability of the air guide cover 40, but also promotes the integration and optimization of the internal structure of the server node housing. The air guide plate 43 and the air guide part 44 are directly set on the mounting surface 41, reducing additional connectors and assembly steps, making the internal layout of the server simpler and providing more installation space for other components.

[0088] like Figure 11 and Figure 12 As shown, the air guide surface 441 includes a first inclined surface 4411, a first transition surface 4412, and a second inclined surface 4413 connected in sequence. Both the first inclined surface 4411 and the second inclined surface 4413 are set at an angle to the first transition surface 4412. Both the first inclined surface 4411 and the second inclined surface 4413 are inclined towards the mounting surface 41, and the first inclined surface 4411 and the second inclined surface 4413 are set at an angle. This, especially the fact that both the first inclined surface 4411 and the second inclined surface 4413 are inclined towards the mounting surface 41 and have a specific angle with the first transition surface 4412, helps optimize the airflow distribution path inside the server node housing. When cold air enters the server, it first comes into contact with the first inclined surface 4411, is then guided to the first transition surface 4412, and finally, guided by the second inclined surface 4413, flows more evenly and efficiently to the critical heat source areas of the server. In this way, the above design can significantly reduce airflow turbulence and resistance, improve heat dissipation efficiency, and ensure that the internal components of the server maintain an ideal temperature level under high load operation, thereby extending the hardware life and improving the overall stability and efficiency of the server operation.

[0089] In this embodiment, by finely adjusting the tilt angle and transition connection method of each component of the air guide surface 441, the noise when high-speed airflow passes through can be effectively reduced. The tilt design of the first tilt surface 4411 and the second tilt surface 4413 enables the airflow to turn more smoothly, reducing eddies and airflow separation caused by sharp turns, thereby reducing wind noise.

[0090] like Figure 11 , Figure 12 as well as Figure 17As shown, the air guide shroud 40 also includes an extension structure 46, which is disposed on the first transition surface 4412. The surface of the extension structure 46 away from the first transition surface 4412 includes a third inclined surface 461, a second transition surface 462, and a fourth inclined surface 463 connected in sequence. The third inclined surface 461 and the fourth inclined surface 463 are both set at an angle to the second transition surface 462. The third inclined surface 461 and the fourth inclined surface 463 are both inclined towards the mounting surface 41. The third inclined surface 461 is coplanar with the first inclined surface 4411, and the fourth inclined surface 463 is coplanar with the second inclined surface 4413. In this way, the air guide shroud assembly can be compatible with memory modules of different heights (such as DDR5 and Tall DDR5). By adjusting or disassembling the extension structure 46, different configurations can be adapted, achieving a high degree of configurability. The flexibility of the above design allows server nodes to quickly upgrade or replace memory as needed without changing the basic structure, improving the adaptability of the server and the flexibility of lifecycle management.

[0091] In this embodiment, the third inclined surface 461 on the extension structure 46 is coplanar with the first inclined surface 4411, and the fourth inclined surface 463 is coplanar with the second inclined surface 4413, and both are inclined toward the mounting surface 41. This can further refine the guiding path of the cold air. The angle between the third inclined surface 461 and the fourth inclined surface 463 and the second transition surface 462 helps to achieve a smooth change and precise distribution of airflow, ensuring that the cold air can flow more evenly and concentratedly to key heat-generating parts such as the CPU heatsink and memory, thereby improving heat exchange efficiency, reducing the operating temperature of these key components, ensuring stable operation of the server under high load, and extending the service life of the hardware.

[0092] like Figure 11 As shown, the extension structure 46 includes a surrounding plate 464 and a sealing plate 465. One side of the surrounding plate 464 is connected to the airflow guide 44, with a portion of the plate forming a third inclined surface 461 and another portion forming a fourth inclined surface 463. The other side of the surrounding plate 464 is connected to the sealing plate 465, with the surface of the sealing plate 465 away from the surrounding plate 464 forming a second transition surface 462. This arrangement, with a portion of the surrounding plate 464 forming the third inclined surface 461 and another portion forming the fourth inclined surface 463, ensures more precise control of airflow as it passes through the airflow guide shroud 40. The inclined design of the third inclined surface 461 and the fourth inclined surface 463 guides cool air directly and efficiently to high-heat-density areas inside the server, such as the CPU and memory modules, thereby improving heat dissipation efficiency. Especially during high-load computing, this effectively reduces the temperature of these components, ensuring stable server operation.

[0093] In this embodiment, the clever connection between the enclosure plate 464 and the sealing plate 465 forms a second transition surface 462, which helps to smooth the airflow direction and reduce airflow resistance and turbulence during the turning process. Lower air resistance means that heat dissipation components such as fans can operate at lower power to achieve the same heat dissipation effect, thereby reducing server energy consumption and improving energy efficiency.

[0094] like Figure 10 and Figure 16 As shown, the server node housing also includes a first snap-fit ​​assembly 70, which includes a first snap-fit ​​portion 71 and a second snap-fit ​​portion 72. The first snap-fit ​​portion 71 is disposed on the flow guide portion 44. The second snap-fit ​​portion 72 is disposed within the enclosure 464; wherein the first snap-fit ​​portion 71 and the second snap-fit ​​portion 72 serve as limiting stops to connect the extension structure 46 and the flow guide portion 44. This limiting stop design of the first snap-fit ​​assembly 70 enables tool-free installation and disassembly between the extension structure 46 and the flow guide portion 44. The operator only needs to align the first snap-fit ​​portion 71 and the second snap-fit ​​portion 72 and apply appropriate force to achieve a quick connection without additional screws or tools, thereby simplifying the assembly process of the server node housing, improving production efficiency, and reducing manufacturing costs.

[0095] In this embodiment, the limiting and stopping structures of the first latching portion 71 and the second latching portion 72 provide a robust mechanical connection, ensuring that the extension structure 46 maintains a tight connection with the airflow guide portion 44 even when facing external interference such as vibration during server operation. This guarantees the integrity of the airflow guidance design and the accuracy of airflow distribution. This is crucial for maintaining stable airflow within the server and ensuring efficient heat dissipation, helping the server maintain a stable operating temperature under various workloads, extending hardware lifespan, and improving system reliability and user experience.

[0096] like Figure 16As shown, the first engaging portion 71 has a through hole, and the second engaging portion 72 includes a third body 721 and at least two spaced-apart extension arms 722. The first end of each extension arm 722 is connected to the third body 721, and the second end of each extension arm 722 has a protruding edge 723. When the second ends of at least two extension arms 722 are deformed and pass through the through hole, and the protruding edge 723 is stopped by the first engaging portion 71, the extension structure 46 engages with the guide portion 44. Thus, the first end of the extension arm 722 of the second engaging portion 72 is connected to the third body 721, and the second end has a protruding edge 723. The second end of the extension arm 722 deforms under appropriate force, thereby passing through the through hole in the first engaging portion 71. When the extension arm 722 passes through the through hole and returns to its original shape, the protruding edge 723 stops the first engaging portion 71, ensuring a stable connection between the extension structure 46 and the guide portion 44. The aforementioned snap-fit ​​mechanism not only simplifies the assembly process and avoids the complexity of using screws or other fasteners, but also provides sufficient mechanical strength to ensure that the connection between the extension structure and the airflow guide will not loosen even if the server encounters vibration or impact during operation, thus guaranteeing the stability of the airflow guidance and heat dissipation effect inside the server.

[0097] In this embodiment, the snap-fit ​​between the first latching part 71 and the second latching part 72 allows for easy connection and disassembly through simple operation, without the need for specialized tools or complex disassembly procedures. When it is necessary to clean the air guide or replace damaged parts, the operator only needs to apply appropriate force to disengage the protrusion 723 of the extension arm 722 from the stop of the first latching part 71, thus easily removing the extension structure 46. This rapid disassembly capability not only reduces maintenance costs and time but also facilitates upgrades to internal server components, such as replacing the heat sink with a more efficient one or adding memory, thereby improving the overall performance and flexibility of the server and meeting the needs of different application scenarios.

[0098] like Figure 14 and Figure 15As shown, the server node housing also includes a second latching assembly 80, which includes a third latching portion 81 and a fourth latching portion 82. The third latching portion 81 is disposed on the air guide shroud 40. The fourth latching portion 82 is disposed on the second bracket 30. One of the third latching portions 81 and the fourth latching portion 82 is a first protrusion, and the other is a first recess. The first protrusion extends into the first recess and is stopped and limited by the first recess to connect the air guide shroud 40 and the second bracket 30. Thus, by disposing of the third latching portion 81 on the air guide shroud 40 and the fourth latching portion 82 on the second bracket 30, and utilizing the physical connection of the first protrusion extending into the first recess, a rigid connection between the air guide shroud 40 and the second bracket 30 is achieved. This significantly enhances the overall structural stability of the server node housing, provides additional support and protection, and ensures the safety of internal components and the stability of server operation.

[0099] In this embodiment, the second snap-fit ​​assembly 80 employs a limiting and stopping method using protrusions and recesses. The operator only needs to align the first protrusion with the first recess and push it in to achieve a quick connection between the air guide shroud 40 and the second bracket 30, without the need for complex hand tools or additional fasteners. This simplified installation procedure not only speeds up the assembly of the server node housing but also reduces assembly costs.

[0100] This application also provides a server node, including a server node housing and a memory 90 disposed within the server node housing; wherein the server node housing is the server node housing described above.

[0101] like Figure 9 and Figure 18 As shown, memory 90 includes a first memory 91 and a second memory 92, and the height of the first memory 91 is smaller than the height of the second memory 92.

[0102] Example 2

[0103] The server node shell in Example 2 differs from that in Example 1 in that the height of the memory used for installation is different.

[0104] like Figures 18 to 21As shown, the air guide shroud 40 also includes an insulating member 45, which is disposed on the first transition surface 4412. The thickness of the insulating member 45 is greater than or equal to 0.2 mm and less than or equal to 1.0 mm. In this way, the insulating member 45 can effectively isolate the air guide shroud 40 from contact with potentially live parts, preventing short circuits caused by contact between the air guide shroud and electrical components due to conductive materials (such as metal supports). At the same time, the thickness of the insulating member is designed between 0.2 mm and 1.0 mm, ensuring sufficient insulation capacity while also considering lightweight design and avoiding unnecessary weight additions, thus achieving a good balance between electrical safety and structural weight.

[0105] In this embodiment, the insulating element 45 is a Mylar sheet. This Mylar sheet has good processability and can be manufactured into various shapes and sizes according to design requirements to meet the insulation needs of different locations on the air guide shroud 40.

[0106] Optionally, the Mylar sheet is glued or snapped onto the first transition surface 4412.

[0107] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0108] The air guide shroud assembly integrates the first and second brackets, replacing the separate installation design of the top cover and air guide shroud in related technologies, thus achieving structural integration. This reduces installation steps, solves the problem of low disassembly and assembly efficiency of the computational node housing in related technologies, improves production efficiency, and also reduces dimensional tolerances accumulated from multiple assembly processes, improving the overall structural accuracy and stability of the node. Simultaneously, the rotatable connection design between the first bracket and the base, combined with the movable locking structure of the locking component, provides a rotary installation and tool-free disassembly solution, making the installation and disassembly of the air guide shroud assembly more convenient and achievable without specialized tools. This significantly improves maintenance and upgrade efficiency while reducing operational difficulty and time costs.

The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
