Description

Technical Field

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

[0002] In data centers and high-performance computing scenarios, drawer-type servers are widely used. These servers typically employ hot-swapping to maintain high-power components, such as the central processing unit (CPU), graphics processing unit (GPU), or power supply module, enabling component replacement and maintenance without downtime.

[0003] In related technologies, when a hot-swapping operation is performed on a node of a server, the node needs to be completely removed from the chassis cavity, resulting in a large gap between the node and the chassis cavity. This causes the cooling airflow to partially bypass the node, causing the temperature of the high-power components inside the node that require heat dissipation to rise sharply within one to two minutes and exceed the safety threshold. This forces the server to reduce its frequency or even shut down, severely limiting the time window for maintenance operations and affecting the practicality and reliability of the hot-swapping function. Summary of the Invention

[0004] This application provides a server that can extend the time window for safe hot-swapping operations, thereby improving the practicality and reliability of the hot-swapping function.

[0005] To achieve the above objectives, the embodiments of this application adopt the following technical solutions: In a first aspect, embodiments of this application provide a server, including: The nodes are equipped with electronic components; The chassis has a receiving cavity, and the node is slidably disposed in the receiving cavity along a first direction; An air guide structure is telescopically connected to a node along a first direction. The air guide structure is provided with an air guide channel for heat dissipation of the node. The air guide structure has a first connecting end and a second connecting end. The first connecting end is fixedly connected to the node, and the second connecting end can move relative to the chassis in the first direction. The cable has one end connected to the node and the other end connected to the optical module inside the chassis. When the node is pulled out of the housing, the air guide structure is in an extended state and the air guide channel runs through the air guide structure. The node and the optical module are connected by a cable.

[0006] According to the server provided in this application embodiment: the node is slidably disposed within the accommodating cavity along a first direction, providing a basis for the node to be pulled out of the accommodating cavity for hot-swapping operations. The node and the optical module are always connected via cables, ensuring that the data link between the node and the optical module is not interrupted during hot-swapping, supporting debugging, diagnosis, or partial function operation under powered conditions. The air guide structure is retractably connected to the node along the first direction, allowing the internal electronic components to be cooled and dissipated under the action of the air guide structure when the node is pulled out of the accommodating cavity for hot-swapping operations, extending the time window for safe thermal maintenance operations. This improves the practicality and reliability of the hot-swapping function.

[0007] In one implementation, the air guiding structure includes: The air guide bracket is connected to the node and forms a first air guide channel that runs through the air guide bracket; The air guide shroud is slidably connected to the air guide bracket along the first direction and forms a second air guide channel that penetrates the air guide shroud; when the node is pulled out of the receiving cavity, the air guide shroud extends relative to the air guide bracket to dissipate heat from the node.

[0008] In this embodiment, an air guide bracket and an air guide shroud are introduced. The air guide shroud is slidably connected to the air guide bracket along a first direction, forming an air guide structure that can extend and retract along the first direction. When the node is pulled out of the housing cavity, the air guide shroud extends relative to the air guide bracket. At this time, the first air guide channel penetrating the air guide bracket and the second air guide channel penetrating the air guide shroud are interconnected to form a continuous air guide channel. The air guide channel connects the inside of the node with the housing cavity, ensuring that the air-cooled airflow can continuously flow through the inside of the node to effectively dissipate heat from the electronic components. That is, the air-cooled airflow can flow sequentially through: the inside of the node, the first air guide channel of the air guide bracket, the second air guide channel of the air guide shroud, and finally into the housing cavity. This design allows the air guide shroud to connect with the air duct inside the housing cavity, guiding the air-cooled airflow into the extracted node. This enables continuous heat dissipation of the internal electronic components during node maintenance, ensuring the heat dissipation effect of the air-cooled airflow on the internal electronic components of the node, effectively extending the time window for safe maintenance operations, and improving the practicality and reliability of the hot-swap function.

[0009] In one implementation, in a first direction, the profile dimensions of the air guide shroud are configured to match the profile dimensions of the receiving cavity.

[0010] In this embodiment, the second air duct is designed based on the outline dimensions of the air duct cover, so that the second air duct and the accommodating cavity form a good fit, thereby effectively improving the smoothness of airflow from the node out and into the accommodating cavity through the air duct, and further improving the heat dissipation efficiency.

[0011] In one implementation, the air guide structure further includes a guide member disposed on the air guide bracket and a constraint member disposed on the air guide shroud; the constraint member is used to cooperate with the guide member and can drive the air guide shroud to move along the guide member.

[0012] In one implementation, the guide element is a guide groove that extends along a first direction; A constraint member is inserted into a guide groove along a second direction so that the constraint member moves along the guide groove, thereby driving the air guide shroud to move along a first direction; wherein the second direction intersects with the first direction.

[0013] In this embodiment of the application, the constraint member drives the air guide cover to extend and retract relative to the air guide bracket along the extension direction of the guide groove, that is, along the first direction.

[0014] In one implementation, the constraint member includes a first part and a second part. The outer diameter of the first part is larger than the width of the guide groove, and the second part passes through the guide groove and is fixedly connected to the air guide cover so that the constraint member passes through the guide groove.

[0015] In this embodiment, the outer diameter of the first part is designed to be larger than the width of the guide groove, so that the first part and the second part can be located on opposite sides of the guide groove along the second direction, avoiding the problem of the constraint member coming out of the guide groove due to external force or vibration, and improving the stability of the connection between the air guide cover and the air guide bracket.

[0016] In one implementation, the air guide structure further includes an elastic element, which is elastically connected between the air guide support and the air guide cover along a first direction and can be selectively in a compressed state or a free state. When the node is loaded into the accommodating cavity, the air guide cover is squeezed by the inner wall of the accommodating cavity, causing the elastic element to be in a compressed state. When the node is pulled out of the receiving cavity, the elastic element is in a free state, allowing the air guide shroud to extend relative to the air guide support.

[0017] In this embodiment, by introducing an elastic element and configuring it to be elastically connected between the air guide bracket and the air guide cover, when the node is loaded into the receiving cavity, the elastic element is compressed by the inner wall of the receiving cavity, keeping the overall air guide structure contracted and compact. When the node is pulled out of the receiving cavity for maintenance, the elastic element returns to its free state, driving the air guide cover to automatically extend relative to the air guide bracket. Thus, the air guide channel can be automatically established and maintained during hot-swapping, continuously guiding the cooling airflow through the inside of the node, achieving effective heat dissipation for electronic devices, significantly extending the time window for safe maintenance operations, and further improving the automation and operational reliability of the hot-swapping function.

[0018] In one implementation, the air guide shroud is sleeved on the air guide bracket along a first direction, and the air guide structure further includes: The first base plate is located on the inner side of the air guide bracket, and one end of the elastic element is connected to the first base plate; The second base plate is located on the air guide hood and is spaced apart from the first base plate along the first direction. The other end of the elastic member is connected to the second base plate.

[0019] In this embodiment, a stable and controllable elastic connection is formed between the air guide bracket and the air guide cover through the cooperation of the first base plate, the second base plate and the elastic element.

[0020] In one implementation, the air guide shroud has a groove extending in a first direction; a second base plate is disposed within the groove; and a first base plate is accommodated within the groove.

[0021] In this embodiment, by providing a groove extending along a first direction on the air guide cover, and accommodating both the second base plate and the first base plate within the groove, the elastic element can be compactly arranged within the confined space between the air guide cover and the air guide support. This improves the utilization rate of the internal space of the air guide structure and avoids interference from additional protrusions or exposed components on the telescopic movement. Furthermore, the groove completely covers and guides the first base plate, the second base plate, and the elastic element.

[0022] In one implementation, the air guiding structure also includes: A first guide pin is connected to the side of the first base plate facing the second base plate, and an elastic element is sleeved on the first guide pin; and / or, The second guide pin is connected to the side of the second base plate facing the first base plate, and the elastic element is sleeved on the second guide pin.

[0023] In this embodiment, the first guide pin and / or the second guide pin provide axial guidance and radial limiting for the compression and rebound process of the elastic element, effectively preventing the elastic element from deflecting or becoming unstable during the extension and retraction process, and ensuring the extension and retraction accuracy and consistency of the air guide cover relative to the air guide bracket. Therefore, when performing hot-swappable operations at the node, the air guide cover can more reliably extend into the receiving cavity, thereby improving the overall reliability of the hot-swappable maintenance process.

Detailed Implementation

[0026] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings. To facilitate a clear description of the technical solutions of the embodiments of this application, the use of terms such as "first," "second," etc., in the embodiments of this application is for illustrative purposes and to distinguish the objects being described. There is no particular order between them, nor does it indicate a specific limitation on the number of devices in the embodiments of this application, and they do not constitute any limitation on the embodiments of this application.

[0027] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0028] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0029] In the description of this application, it should be understood that the terms "upper," "lower," "horizontal," "bottom," "inner," and "outer" (if any) indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In this application, unless otherwise expressly specified and limited, "upper" or "lower" of the first feature and the second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0030] In this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two entities at the point of connection are not connected through a transitional structure, but are simply linked together to form a whole. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0031] In this application, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0032] In data centers and high-performance computing scenarios, drawer-type servers are widely used. These servers typically employ hot-swapping to maintain high-power components, enabling component replacement and maintenance without downtime, thereby improving the system's continuous operation capability.

[0033] This application provides a server that allows for the replacement or maintenance of its internal electronic components via hot-swapping.

[0034] Figure 1A This is a schematic diagram of the structure of a server provided in an embodiment of this application.

[0035] Reference Figure 1AAs shown in the embodiment of this application, the server 100 includes a chassis 101 and a node 102. The node 102 is equipped with electronic devices, which are used to realize functions such as data processing, transmission, storage or resource coordination.

[0036] The chassis 101 is provided with a receiving cavity 1011, and the node 102 is slidably disposed in the receiving cavity 1011 along the first direction to provide a basis for hot-plugging the node 102.

[0037] Here, the first direction can refer to the direction shown by T1 in FIG1. ​​This application embodiment does not impose specific limitations on the first direction. Node 102 can slide along the direction shown by T1 in FIG1 to be inserted into the receiving cavity 1011; node 102 can be pulled out of the receiving cavity 1011 in the opposite direction to the direction shown by T1 in FIG1.

[0038] In some implementations, the electronic devices may include, but are not limited to, optical modules, hard disks, high-power cards, or network cards.

[0039] In some embodiments, the accommodating cavity 1011 is provided with an insertion port (not shown in the figure), and the node 102 is inserted into the accommodating cavity 1011 through the insertion port.

[0040] In some implementations, server 100 also includes a cable (not shown), one end of which is connected to node 102 (which can be understood as the second node below), and the other end of which is connected to an optical module (not shown) inside the chassis 101 to enable data communication between the electronic devices inside node 102 and the optical module.

[0041] like Figure 1A In the example shown, server 100 includes two nodes, namely a first node and a second node. The first node includes an optical module, and the second node is connected to the optical module via a cable, thereby enabling data communication between the first node and the second node.

[0042] Accordingly, the chassis 101 has two accommodating cavities 1011 along the second direction, namely a first accommodating cavity and a second accommodating cavity. The first accommodating cavity is located above the second accommodating cavity ("above" is only used in conjunction with the illustration and does not constitute a limitation on the relative position of the first and second accommodating cavities), and the first node is loaded in the first accommodating cavity (which can be understood as...). Figure 1A Within the 1011 marker, the second node (which can be understood as...) Figure 1A (102 marked in the text) is slidably disposed in the second accommodating cavity.

[0043] In some examples, the height dimension of the first accommodating cavity in the second direction is a first height m1, and the height dimension of the second accommodating cavity in the second direction is a second height m2. The first height m1 can be 2U (1U can be 44.55 mm), and the second height m2 can be 3U. The embodiments of this application do not limit the height dimensions of the first accommodating cavity and the second accommodating cavity.

[0044] In some examples, the first node may include a switch board or network board, an optical module, etc. The switch board may be equipped with a switching chip, a central processing unit, memory, and a management controller. In this case, the first node can perform data decision-making, data management, and data exchange, and connect to and convert signals with the outside world.

[0045] like Figure 1A In the example shown, the first accommodating cavity includes a first region 103, within which the optical module is housed. The first region 103 is located at the insertion port of the first accommodating cavity and is close to the second accommodating cavity. In other words, the optical module is located in the first region 103, meaning that the end of the first accommodating cavity near the insertion port has a built-in cable connection card.

[0046] In some implementations, the cable can be an optical fiber. In this case, one end of the optical fiber connects to the PCB board of the optical module itself; specifically, it connects to the optical module interface inside the optical module. The optical module is configured to convert electrical signals within server 100 into optical signals. The other end of the optical fiber connects to one end of a fiber optic adapter panel on chassis 101 or a backplane. The other end of the fiber optic adapter panel is then connected to other servers or switching devices in the network via another standard fiber optic patch cord. Thus, high-speed serial data signals are transmitted from the first node to the external network via the optical fiber cable and fiber optic patch cord.

[0047] In some examples, the second node may include multiple hard drives for data storage. Accordingly, the switch board can connect to the hard drives of the second node via high-speed cables to access the data.

[0048] During maintenance of the second node, the cables of the optical module located in the first region 103 above it may affect the operating space of the second node. Therefore, it is necessary to pull the entire second node out of the second accommodating cavity to replace or maintain its electronic components. Accordingly, during thermal maintenance of the second node, a gap exists between the second node and the accommodating cavity 1011 along the direction of insertion and removal of the second node. Specifically, the second node is pulled out of the second accommodating cavity in the opposite direction of the loading direction.

[0049] It should be noted that the first and second nodes mentioned above are merely examples and do not constitute a limitation on the internal composition of server 100.

[0050] Here, the second direction can be referenced. Figure 1A As shown in T2, this application embodiment does not impose specific restrictions on the second direction.

[0051] In other embodiments of this application, the server 100 may also include three or more cavities 1011. Accordingly, each cavity 1011 contains a node 102, and whether the node 102 is slidably disposed depends on whether hot-swappable operation is required. In other words, if hot-swappable maintenance of the electronic components of the node 102 is required, the node 102 is slidably disposed within the cavity 1011; if hot-swappable maintenance of the electronic components of the node 102 is not required, the node is disposed within the cavity 1011.

[0052] Figure 1B This is a second schematic diagram of the structure of a server provided in an embodiment of this application, showing the server 100 interacting with... Figure 1A Relative orientation structure. In some implementations, server 100 can be cooled by air cooling. Specifically, the air cooling airflow can be configured along the direction in which node 102 is inserted into accommodating cavity 1011 (see reference). Figure 1B The airflow (in the direction shown by T1) flows through server 100 to dissipate heat from server 100.

[0053] In some embodiments, server 100 includes an axial fan located at the rear of chassis 101 along a first direction; node 102 has an air inlet at the front of the first direction. Under the action of the axial fan, the cooled airflow enters node 102 from the front of the first direction through the air inlet, then exits node 102 from the rear of the first direction, and finally flows from the rear of chassis 101 to the outside of server 100.

[0054] Reference Figure 1B In the example shown, the first accommodating cavity has three air-cooling zones 104, all of which are used to house axial fans to dissipate heat from the electronic components in the first node; the second accommodating cavity has five air-cooling zones 104, all of which are used to house axial fans to dissipate heat from the electronic components in the second node.

[0055] It should be noted that the three air-cooled zones 104 of the first accommodating cavity and the five air-cooled zones 104 of the second accommodating cavity mentioned above are only examples. In practice, the position and number of air-cooled zones 104 can be flexibly set according to heat dissipation requirements, and do not constitute a limitation on the position and number of fans.

[0056] Figure 1C This is a schematic diagram of a server in a hot-swappable state provided in an embodiment of this application.

[0057] Combination Figure 1CAs shown in the embodiment of this application, the server 100 further includes an air guide structure 200, which is retractably connected to the node 102 along a first direction. The air guide structure 200 is provided with an air guide channel (not shown in the figure), which is used to dissipate heat from the node 102. In other words, the air guide channel is used to guide the air-cooled airflow through the interior of the node 102 to dissipate heat from the electronic components of the node 102.

[0058] Figure 1D This is a schematic diagram of the structure of a node in a server provided in an embodiment of this application.

[0059] Combination Figure 1D As shown, in some embodiments, node 102 includes a plurality of hard disks 1022. Under the action of an axial fan, a cooling airflow flows over the surface of the hard disks 1022 in a first direction to absorb the heat of the hard disks 1022. Accordingly, the cooling airflow that has absorbed heat flows out of node 102 through the tail end in the first direction.

[0060] exist Figure 1D In the example shown, node 102 includes 40 hard disks 1022, arranged in 4 rows along a first direction and 10 columns along a third direction (in... Figure 1D (Only two examples are shown in the text).

[0061] In other embodiments of this application, node 102 may include other numbers of hard disks 1022. This application embodiment does not limit the number and layout of hard disks 1022 included in node 102.

[0062] It is easy to understand that the above-mentioned node 102, including the hard disk 1022, is only an example of the composition of node 102 and does not constitute a limitation on the types of electronic devices included in node 102.

[0063] To facilitate the description of the positional relationship between node 102 and the air guide structure 200, when node 102 is loaded into the receiving cavity 1011 along the first direction, the end that first enters the receiving cavity 1011 is the rear end 102b of node 102, and the end that enters the receiving cavity 1011 later is the front end 102a of node 102. In other words, when node 102 is located inside the receiving cavity 1011, in the first direction, the end closer to the insertion port of the receiving cavity 1011 is the front end of node 102, and the end farther away from the insertion port of the receiving cavity 1011 is the rear end 102b of node 102.

[0064] Figure 1E This is a schematic diagram of the structure of the backplane of a node in a server provided in an embodiment of this application.

[0065] Reference Figure 1EAs shown, in some embodiments, the rear end 102b of node 102 is provided with a back plate 1023, and the back plate 1023 is provided with a vent 1025 corresponding to the hard disk 1022, so that the air-cooled airflow flowing through the hard disk 1022 flows from the vent 1025 to the outside of node 102.

[0066] In some embodiments, node 102 is provided with multiple rows of hard disks 1022 spaced along a third direction, and back panel 1023 is provided with multiple air holes 1025 spaced along a third direction, each air hole corresponding to a row of hard disks 1022, so that the air-cooled airflow flowing through the row of hard disks 1022 flows from the corresponding air hole 1025 to the outside of node 102.

[0067] Reference Figure 1D and Figure 1E In the example, node 102 is provided with 10 columns of hard disks 1022 spaced along the third direction, and back panel 1023 is provided with 10 air holes 1025 spaced along the third direction. Each air hole corresponds to a column of hard disks 1022, so that the air-cooled airflow passing through the column of hard disks 1022 flows from the corresponding air hole 1025 to the outside of node 102.

[0068] In some embodiments, a vent located in the third direction includes a plurality of sub-vents (not shown) spaced apart along the second direction. The plurality of sub-vents correspond to the heat-generating areas of the hard disk 1022 along the second direction, so as to guide the air-cooling airflow more precisely through the heat-generating areas of the hard disk 1022 and improve the heat dissipation effect.

[0069] In some embodiments, the back plate 1023 may also be provided with a partition area 1027, which is used to install the partition plate 1026. In other words, the partition plate 1026 is connected to the partition area 1027 so that the back plate 1023 and the partition plate 1026 form a flow guide area in the first direction, so that the air-cooled airflow can flow along the flow guide area after flowing from the air hole 1025 to the outside of the node 102, thereby reducing airflow turbulence and optimizing the air-cooling path.

[0070] Combination Figure 1C As shown, in some embodiments, the air guide structure 200 has a first connecting end 201 and a second connecting end 202 disposed opposite to each other along a first direction. The first connecting end 201 is fixedly connected to the node 102, and the second connecting end 202 is movably connected to the chassis 101.

[0071] In the above scheme, when node 102 is inserted into the accommodating cavity 1011, the second connecting end 202 moves towards the side closer to the first connecting end 201, so that the air guiding structure 200 is in a contracted state; when node 102 is pulled out of the accommodating cavity 1011, the second connecting end 202 moves away from the first connecting end 201, so that the air guiding structure 200 is in an extended state.

[0072] When the air guide structure 200 is in its extended state, the second connecting end 202 of the air guide structure is at least flush with the insertion port of the accommodating cavity 1011, so that the air guide channel connects to the interior of the accommodating cavity 1011, thereby maintaining a continuous path for the cooling airflow, that is, the air-cooled airflow flows through the interior of node 102 into the accommodating cavity 1011. At this time, node 102 is connected to the optical module through the cable.

[0073] In some examples, the first connection end 201 is connected to the rear end 102b of node 102, and the second connection end 202 is a movable end. The movable end can extend or retract along a first direction toward or away from the first connection end 201.

[0074] In some embodiments, the first connection end 201 of the air guide structure 200 is fastened to the back plate 1023 of the node 102 by fasteners to realize the connection between the air guide structure 200 and the node 102.

[0075] In some examples, the fasteners can be screws, bolts or other threaded fasteners, etc., and the embodiments of this application do not limit the types of fasteners.

[0076] In some embodiments, an air guiding channel is formed inside the air guiding structure 200, and the air guiding channel runs through the air guiding structure 200. In other words, the air guiding channel has a first end and a second end, and the first end and the second end are connected. Then, the first connecting end 201 of the air guiding structure 200 is connected to the back plate 1023 of the node 102, and the first end of the air guiding channel is connected to the air hole 1025 of the back plate 1023. Thus, the air-cooled airflow flowing through the hard disk 1022 can flow into the air guiding channel through the air hole 1025 and the first end of the air guiding channel.

[0077] In some examples, the first connecting end 201 and the second connecting end 202 are disposed opposite to each other in the air guide structure 200 along a first direction. The first end and the second end of the air guide channel are also disposed opposite to each other in the first direction.

[0078] Figure 2A This is a schematic diagram of the structure of a server provided in an embodiment of this application, showing the structure of the air guide channel and the air-cooling zone when the node is loaded in the accommodating cavity. Figure 2B yes Figure 2A A magnified structural diagram of point A in the server shown.

[0079] Reference Figure 2A and Figure 2BAs shown, in some embodiments, when node 102 is inserted into the accommodating cavity 1011, the second connecting end 202 of the air guide structure 200 is aligned with the air-cooled zone 104 in the first direction, so that the second connecting end 202 is connected to the air-cooled zone 104. This achieves communication between the air guide channel 2001 and the air-cooled zone 104. Under the action of the axial fan, the air-cooled airflow passes through the hard disk 1022, sequentially through the air vents 1025, and flows through the air guide channel 2001 to the air-cooled zone 104.

[0080] It should be noted that the server chassis 101 is also equipped with an air outlet, which connects the ventilation and cooling zone 104 to the outside of the chassis 101, so that the air-cooled airflow flowing to the ventilation and cooling zone 104 is discharged to the outside of the server 100 through the air outlet. This will not be described in detail here.

[0081] Figure 2C yes Figure 1C The diagram shows an enlarged view of the structure at point B in the server shown.

[0082] Reference Figure 1C and Figure 2C As shown, in some embodiments, when node 102 is pulled out of the accommodating cavity 1011, the air guide structure 200 is in an extended state, and its second connecting end 202 is at least flush with the insertion port of the accommodating cavity 1011, so that the second connecting end 202 is connected to the insertion port side of the accommodating cavity 1011. Thus, the air guide channel 2001 is connected to the accommodating cavity 1011. Furthermore, because the air-cooled zone 104 is located at the rear end of the accommodating cavity 1011 along the first direction, under the action of the axial fan, the air-cooled airflow flows through the hard disk 1022, and sequentially through the air hole 1025, the air guide channel 2001, and the accommodating cavity 1011 to the air-cooled zone 104.

[0083] In some examples, the second connection end 202 is configured such that, when the air guide structure 200 is in an extended state, the second connection end 202 is flush with the insertion port of the accommodating cavity 1011 in the first direction. At this time, there is no gap between the second connection end 202 and the accommodating cavity 1011 in the first direction, allowing the air-cooled airflow to flow through the node 102 and then enter the accommodating cavity 1011 through the air guide channel 2001.

[0084] In other examples, the second connection end 202 is configured to extend at least partially into the receiving cavity 1011 when the air guide structure 200 is in an extended state. This ensures that the second connection end 202 is in communication with the receiving cavity 1011 in the first direction. Accordingly, the air-cooled airflow flows from the node 102 and enters the receiving cavity 1011 through the air guide channel 2001.

[0085] According to the server 100 provided in the embodiments of this application: Node 102 is slidably disposed in the accommodating cavity 1011 along a first direction, providing a basis for node 102 to be pulled out of the accommodating cavity 1011 for hot-swapping operation. Node 102 and the optical module are always connected through a cable, ensuring that the data link between node 102 and the optical module is not interrupted during hot-swapping, supporting debugging, diagnosis, or partial function operation under power-on conditions; the air guide structure 200 is retractably connected to node 102 along the first direction, so that when node 102 is pulled out of the accommodating cavity 1011 for hot-swapping operation, it can also dissipate heat and cool down the internal electronic components under the action of the air guide structure 200, extending the time window for safe thermal maintenance operation and improving the practicality and reliability of the hot-swapping function.

[0086] Figure 2D This is a schematic diagram of a wind-guiding structure in a server provided in an embodiment of this application.

[0087] Reference Figure 2C and Figure 2D As shown, in some embodiments, the air guide structure 200 includes an air guide bracket 20 and an air guide shroud 30. The air guide bracket 20 is connected to the node 102; the air guide shroud 30 is slidably connected to the air guide bracket 20 along a first direction; when the node 102 is pulled out of the receiving cavity 1011, the air guide shroud 30 extends relative to the air guide bracket 20 to partially lie in the receiving cavity 1011.

[0088] Correspondingly, the air guide bracket 20 has a first air guide duct 21 that penetrates the air guide bracket 20, and the air guide shroud 30 has a second air guide duct 31 that penetrates the air guide shroud 30. The first air guide duct 21 connects the interior of the node 102 with the second air guide duct 31. When the air guide shroud 30 extends relative to the air guide bracket 20, the second air guide duct 31 also connects to the receiving cavity 1011.

[0089] Therefore, an air guide bracket 20 and an air guide shroud 30 are introduced. The air guide shroud 30 is slidably connected to the air guide bracket 20 along a first direction, forming an air guide structure 200 that can extend and retract along the first direction. When node 102 is pulled out of the accommodating cavity 1011, the air guide shroud 30 extends relative to the air guide bracket 20. At this time, the first air guide channel 21 penetrating the air guide bracket 20 and the second air guide channel 31 penetrating the air guide shroud 30 are interconnected to form a continuous air guide channel. The air guide channel connects the inside of node 102 with the accommodating cavity 1011 of the chassis 101, ensuring that the air-cooled airflow can continuously flow through the inside of node 102 to effectively dissipate heat from electronic components. That is, the air-cooled airflow can flow sequentially through: the inside of node 102, the first air guide channel 21 of the air guide bracket 20, the second air guide channel 31 of the air guide shroud 30, and finally into the accommodating cavity 1011. This design connects the air guide shroud 30 to the interior of the accommodating cavity 1011, guiding the air-cooled airflow along the first direction from the front end 102a of the node 102 into the interior of the extracted node 102. This allows for continuous heat dissipation of the internal electronic components during the maintenance of the node 102, ensuring the heat dissipation effect of the air-cooled airflow on the internal electronic components of the node 102. This effectively extends the time window during which maintenance operations can be safely performed, and improves the practicality and reliability of the hot-swap function.

[0090] Figure 3A This is a schematic diagram of the structure of a wind guide bracket in a server provided in an embodiment of this application.

[0091] Combination Figure 3A As shown, in some embodiments, the air guide bracket 20 includes a first plate 20a and a second plate 20b extending perpendicularly from the three end faces of the first plate 20a along the T1 direction. The second plate 20b is perpendicular to the first plate 20a and is located on the same side as the first plate 20a. The first plate 20a has at least one first hole 211 extending along a first direction, so that the first plate 20a and the second plate 20b surround and form a first air guide channel 21.

[0092] The first hole 211 is connected to the interior of node 102 so that the first air guide duct 21 is connected to the interior of node 102.

[0093] In some embodiments, the first hole 211 corresponds to the air hole 1025 on the back plate 1023 of the node 102 in a first direction, so that the first hole 211 is connected to the interior of the node 102 through the air hole 1025; thereby, the first air duct 21 is connected to the interior of the node 102.

[0094] In some examples, the projection of the first hole 211 and the air hole 1025 in the first direction coincides, so that the air-cooled airflow from the air hole 1025 can flow into the first air guide duct 21 through the first hole 211.

[0095] In some embodiments, the first plate 20a of the air guide bracket 20 is connected to the back plate 1023, thereby connecting the air guide structure 200 to the node 102.

[0096] In some examples, the first plate 20a is provided with a first connection hole 2011 extending in a first direction, and the back plate 1023 is provided with a second connection hole 1028 extending in a second direction. The first plate 20a and the back plate 1023 are connected by fasteners passing through the first connection hole 2011 and the second connection hole 1028.

[0097] It should be noted that in order to connect the air guide bracket 20 to the back plate 1023, the first hole 211 on the first plate 20a needs to be set to avoid the first connection hole 2011, which will not be elaborated here.

[0098] Combination Figure 1D As shown, in some embodiments, node 102 is provided with a cable box 1021 at the bottom along the second direction. The cable box 1021 is used to accommodate cables so that the hard disk 1022 can be connected to other electronic devices in the server 100 via cables. The embodiments in which the hard disk 1022 is connected to other electronic devices via cables have been described above and will not be repeated here.

[0099] Because the connection path to other electronic devices changes when node 102 is inserted into or removed from the receiving cavity 1011. Specifically, when node 102 is inserted into the receiving cavity 1011, the cable path to other layer nodes in the second direction is shorter; when node 102 is pulled out of the receiving cavity 1011, the cable path to other layer nodes in the second direction is longer.

[0100] Therefore, in order to adapt to the changes in cable routing path during the switching between plugging and unplugging of node 102, in some embodiments, node 102 is also provided with a tank chain (not shown) at the bottom along the second direction. The tank chain is pulled out as node 102 is pulled out, or folded and compressed as node 102 is inserted into the receiving cavity 1011, so that the cable is orderly constrained in the cable box 1021 and will not be suspended or obstruct other surrounding cables.

[0101] In some examples, the tank chain is positioned outside one side wall of the cable box 1021 along a third direction to mate with the cable box 1021.

[0102] In some embodiments, the air guide bracket 20 is provided with a cable passage area 271, which is located at the bottom of the air guide bracket 20 along the second direction and corresponds to the cable box 1021, so that the cables in the cable box 1021 can pass through the cable passage area to other layer nodes located in the second direction.

[0103] In some examples, the line crossing area 271 can be constructed as a first plate 20a cut out along a first direction.

[0104] In some embodiments, the tank chain includes a fixed end and a movable end, with the fixed end connected to the housing 101 and the movable end connected to the node 102. Accordingly, the air guide bracket 20 is provided with a first notch 272 through which the tank chain passes and connects to the housing 101 and the node 102. Thus, the first notch 272 serves to avoid interference with the tank chain, preventing the air guide bracket 20 from interfering with it.

[0105] In some implementations, a signal regenerator (Retimer) board is provided on the backplane 1023. The Retimer board is used to receive the transmitted signal, process it, and output it to improve the signal transmission quality.

[0106] In some embodiments, the air guide bracket 20 is provided with a second notch 28, and the Retimer board of node 102 is at least partially located in the second notch 28. Thus, by providing the second notch 28, the air guide bracket 20 will not interfere with the Retimer board.

[0107] Figure 3B This is a schematic diagram of the structure of a wind deflector in a server provided in an embodiment of this application.

[0108] Reference Figure 3B As shown, in some embodiments, the air guide shroud 30 includes multiple plates connected sequentially to form a second air guide duct 31 extending along a first direction. The air guide shroud 30 is at least partially mounted on the first air guide duct 21, and the first hole 211 of the air guide bracket 20 is aligned with the second air guide duct 31 in the first direction, so that the first air guide duct 21 and the second air guide duct 31 are in communication.

[0109] When the air guide structure 200 is in the extended state, the other end of the air guide shroud 30, which is away from the first hole 211 along the first direction, is located at the insertion port of the receiving cavity 1011, so that the second air guide channel 31 is connected to the receiving cavity 1011. Thus, the interior of the node 102 is connected to the receiving cavity 1011 by the air guide shroud 30 and the air guide bracket 20, which are slidably connected.

[0110] In other words, the air guide shroud 30 includes a first plate 30a and a second plate 30c arranged opposite each other along a third direction, and a third plate 30b and a fourth plate 30d arranged opposite each other along a second direction. The third plate 30b is connected to the first plate 30a and the second plate 30c, and the fourth plate 30d is connected to the first plate 30a and the second plate 30c. In other words, the first plate 30a, the third plate 30b, the second plate 30c, and the fourth plate 30d are sequentially connected to form the air guide shroud 30, and the first plate 30a, the third plate 30b, the second plate 30c, and the fourth plate 30d surround and form a second air guide duct 31.

[0111] In some embodiments, in the first direction, the profile dimensions of the air guide shroud 30 are configured to match the profile dimensions of the receiving cavity 1011. Thus, the second air guide duct 31 is designed based on the profile dimensions of the air guide shroud 30, ensuring a good fit between the second air guide duct 31 and the receiving cavity 1011. This effectively improves the smoothness of airflow from the rear end 102b of node 102, through the air guide channel 2001, into the receiving cavity 1011, further enhancing heat dissipation efficiency.

[0112] In some embodiments, the outline dimensions of the air guide shroud 30 are configured to match the outline dimensions of the receiving cavity 1011. In other words, during the insertion of the node 102 into the receiving cavity 1011, the outer wall of the air guide shroud 30 is at least partially in contact with the inner wall of the receiving cavity 1011, so that the air guide shroud can be inserted into the receiving cavity 1011 under the guidance of the inner wall of the receiving cavity 1011.

[0113] Specifically, when node 102 is pushed into the accommodating cavity 1011, the air guide shroud 30 enters the opening of the accommodating cavity 1011 before node 102. Since its outline dimensions are consistent with the accommodating cavity 1011, the outer wall of the air guide shroud 30 will at least partially contact the inner wall of the accommodating cavity 1011. Therefore, the inner wall of the accommodating cavity 1011 acts as a guide rail, providing additional radial support and guidance for the air guide shroud 30, ensuring a smooth and stable insertion process. Furthermore, this dimensional design creates an almost seamless connection between the second air guide duct 31 and the accommodating cavity 1011. The air-cooled airflow can be smoothly introduced into the accommodating cavity 1011 from the second air guide duct 31, optimizing the heat dissipation path of the air-cooled airflow.

[0114] In other embodiments, the outline dimensions of the air guide shroud 30 are slightly smaller than the outline dimensions of the receiving cavity 1011. In other words, the air guide shroud 30 is suspended inside the receiving cavity 1011 during the insertion of the node 102 into the receiving cavity 1011.

[0115] It is easy to understand that the inner wall of the accommodating cavity 1011 is provided with a sliding structure, and the node 102 is slidably connected to the sliding structure. Under the action of the sliding structure, the node 102 can be inserted into or removed from the accommodating cavity 1011 in the first direction or the opposite direction of the first direction.

[0116] At this time, when node 102 is pushed into the accommodating cavity 1011, the sliding structure cooperates with node 102, and the air guide shroud 30 is pushed into the accommodating cavity 1011 along with the movement of node 102, without needing to rub against the inner wall of the accommodating cavity 1011.

[0117] The following are some examples of how the profile dimensions of the air guide shroud 30 match the profile dimensions of the receiving cavity 1011 in the first direction.

[0118] Combination Figure 3BAs shown, as an example, the first dimension d11 of the air guide shroud 30 along the second direction is slightly smaller than the second dimension of the receiving cavity along the second direction (not shown in the figure). While ensuring that the air guide shroud 30 can at least partially extend into the receiving cavity 1011, the difference between the first dimension d11 and the second dimension can be configured to be as small as possible. This allows the cross-sectional dimension of the second air guide duct 31 along the first direction to be as large as possible, providing greater effective flow for the air-cooled airflow, which is beneficial for increasing the flow efficiency of the air-cooled airflow and thus improving heat dissipation efficiency.

[0119] Here, the first dimension d11 can be understood as the distance between the surfaces of the third plate 30b and the fourth plate 30d facing away from each other along the second direction. The second dimension can be understood as the distance between the relative inner walls of the accommodating cavity 1011 along the second direction.

[0120] As another example, the third dimension d12 of the air guide shroud 30 along the third direction is slightly smaller than the fourth dimension (not shown) of the receiving cavity 1011 along the third direction. While ensuring that the air guide shroud 30 can at least partially extend into the receiving cavity 1011, the difference between the third dimension d12 and the fourth dimension can be configured to be as small as possible. This allows the cross-sectional dimension of the second air duct 31 along the second direction to be as large as possible, providing greater effective flow for the air-cooled airflow, which is beneficial for increasing the flow efficiency of the air-cooled airflow and thus improving heat dissipation efficiency.

[0121] In some embodiments, the air deflector 30 is provided with a third notch 32 through which the tank chain passes to connect to the chassis 101 and the node 102. Thus, the third notch 32 is used to avoid the tank chain so that the air deflector 30 does not interfere with the tank chain.

[0122] Here, the third gap 32 and the first gap 272 correspond in the first direction. In other words, the projections of the third gap 32 and the first gap 272 in the first direction coincide.

[0123] In some examples, the fourth plate 30d may include a first sub-plate 11, a second sub-plate 12, and a third sub-plate 13, arranged sequentially along a third direction, with the second sub-plate 12 closer to the second plate 30c than the first sub-plate 11 and the third sub-plate 13. In this case, the first sub-plate 11 and the second sub-plate 12 are connected along the third direction to each other via a first connecting plate (not shown), and the second sub-plate 12 and the third sub-plate 13 are connected along the third direction to each other via a second connecting plate (not shown). Thus, a third gap 32 is formed between the first connecting plate, the second sub-plate 12, and the second connecting plate. The projection of the third gap 32 in the first direction at least covers the tank chain.

[0124] In some embodiments, the air guide shroud 30 is provided with a fourth notch 33, and the Retimer board of node 102 is at least partially located in the fourth notch 33. Thus, by providing the fourth notch 33, the air guide shroud 30 will not interfere with the Retimer board.

[0125] Here, the fourth gap 33 and the second gap 28 correspond in the first direction. In other words, the projections of the fourth gap 33 and the second gap 28 in the first direction coincide.

[0126] In some examples, the fourth board 30d also includes a fourth sub-board 14. The second sub-board 12, the third sub-board 13, and the fourth sub-board 14 are arranged sequentially along a third direction, with the fourth sub-board 14 being closer to the second board 30c than the third sub-board 13. The third sub-board 13 and the fourth sub-board 14 are connected along the third direction on the side closest to each other by a third connecting plate (not shown). Thus, the fourth sub-board 14 and the third connecting plate enclose a fourth notch 33. The projection of the fourth notch 33 in the first direction at least covers the Retimer board.

[0127] In some embodiments, the projection of the area enclosed by the third connecting plate, the third sub-plate 13, the second connecting plate, and the second plate body 30c in the first direction at least covers the cable box 1021 so that the cable can pass through the air guide channel.

[0128] In some embodiments, the air guide shroud 30 is provided with ribs 311, which are connected between the inner walls of the second air guide duct 31 to enhance the strength of the air guide shroud 30.

[0129] It is understandable that the baffle 311 can be set in the area of ​​the second air duct 31 that does not correspond to the first hole 211 of the air guide bracket 20, so as to avoid affecting the air guiding efficiency of the air guide channel.

[0130] Reference Figure 3B For example, the rib 311 can be a plate-like structure as a whole, and the opposite ends of the rib 311 can be connected between the third plate 30b and the fourth plate 30d. In this case, the rib 311 is arranged as a whole within the air guide shroud 30 along the second direction.

[0131] Specifically, the two ends of the rib 311 can be connected between the third plate 30b and the fourth sub-plate 14.

[0132] Reference Figure 3B For example, the air guide shroud 30 is provided with two first ribs (not shown) spaced apart along a third direction, and the two first ribs are respectively connected between the third plate 30b and the fourth sub-plate 14. In this case, the air guide shroud 30 may also include a second rib connected between the two first ribs, and the second rib is arranged entirely within the air guide shroud 30 along a third direction.

[0133] Reference Figure 3B For example, the air guide shroud 30 is provided with a third rib (not shown) that connects the two ends of the third plate 30b and the third sub-plate 13. In this case, the air guide shroud 30 may also include a fourth rib (not shown) that connects the third rib and the second connecting plate, and the fourth rib is arranged in the third direction within the air guide shroud 30.

[0134] Figure 4 This is a schematic diagram of the cross-sectional structure of a wind-guiding structure in a server in a first direction, provided in an embodiment of this application.

[0135] Reference Figure 3A and Figure 4 As shown, in some embodiments, the air guide structure 200 further includes a guide member 41 disposed on the air guide bracket 20 and a constraint member 42 disposed on the air guide cover 30; the constraint member 42 is used to cooperate with the guide member 41 and can drive the air guide cover 30 to move along the guide member 41, thereby the air guide cover 30 is slidably connected to the air guide bracket 20 along the first direction.

[0136] In some embodiments, the air guide structure 200 is provided with a plurality of guide members 41 and a plurality of constraint members 42 spaced apart along the second direction. The number of guide members 41 and constraint members 42 is equal, and the guide members 41 and constraint members 42 at corresponding positions cooperate with each other so that the constraint members 42 smoothly drive the air guide cover 30 to move along the guide members 41 under the action of the guide members 41.

[0137] In some examples, the number of guide members 41 can be two, three, or other numbers; the embodiments of this application do not limit the number of guide members 41. Correspondingly, the number of constraint members 42 is equal to the number of guide members 41.

[0138] In some examples, the guide member 41 can be constructed as a groove extending along the first direction, and the constraint member 42 can be constructed as a protrusion. The protrusion is embedded in the groove and can move along the extension direction of the groove, so that the protrusion drives the air guide cover 30 to extend and retract relative to the air guide bracket 20 along the extension direction of the groove, that is, along the first direction.

[0139] Specifically, when node 102 is loaded into accommodating cavity 1011, by configuring the protrusion to move towards the air guide bracket 20 along the extension direction of the groove, the air guide shroud 30 moves towards the side closer to the air guide bracket 20, so that the air guide structure 200 is in a retracted state. When node 102 is pulled out of accommodating cavity 1011, by configuring the protrusion to move away from the air guide bracket 20 along the extension direction of the groove, the air guide shroud 30 moves away from the side closer to the air guide bracket 20, so that the air guide structure 200 is in an extended state.

[0140] In other examples, the guide 41 can be constructed as a slide rail extending along the first direction, and the constraint 42 can be constructed as a slider. The slider is slidably connected to the slide rail along the first direction, so that the slider drives the air guide shroud 30 to extend and retract relative to the air guide bracket 20 along the extension direction of the slide rail, that is, along the first direction.

[0141] Figure 5A This is a schematic diagram of a server's airflow structure in a contracted state, provided in an embodiment of this application.

[0142] Reference Figure 5A As shown, in some embodiments, the guide member 41 is a guide groove that extends along a first direction; the constraint member passes through the guide groove along a second direction so that the constraint member 42 moves along the guide groove, thereby driving the air guide shroud to move along the first direction. Thus, the constraint member 42 drives the air guide shroud 30 to extend and retract relative to the air guide bracket 20 along the extension direction of the guide groove, that is, along the first direction.

[0143] Reference Figure 5A In the example shown, with node 102 loaded in accommodating cavity 1011, constraint member 42 is configured to move to the first extreme position of guide groove (which can be understood as: the foremost end of guide groove along the first direction), so that air guide shroud 30 retracts to be mostly located within the first air guide duct 21, i.e., air guide structure 200 is in a retracted state.

[0144] Figure 5B This is a schematic diagram of a server air guide structure in a state between contraction and extension, provided in an embodiment of this application.

[0145] Reference Figure 5B As shown, when node 102 is pulled out of the accommodating cavity 1011 and the constraint member 42 is moved to the middle position of the guide groove (which can be understood as: any position between the two ends of the guide groove along the first direction), the air guide shroud 30 is located less in the first air guide duct 21 compared to the retracted state.

[0146] Figure 5C This is a schematic diagram of a server's air guide structure in an extended state, provided in an embodiment of this application.

[0147] Reference Figure 5C As shown, when node 102 is pulled out of the accommodating cavity 1011, the constraint member 42 is configured to move to the second limit position of the guide groove (which can be understood as: the rear end of the guide groove along the first direction), so that the air guide shroud 30 is located within the first air guide duct 21 at the minimum, that is, the air guide structure 200 is in the extended state.

[0148] The first and second limit positions are located at the two ends of the guide groove along the extension direction, thereby limiting the movement of the air guide shroud 30 relative to the air guide bracket 20 in the first direction.

[0149] In some examples, the constraint 42 can be fixedly connected to the air guide shroud 30 by means of a threaded connection, so that the air guide shroud 30 can move along the extension direction of the guide groove together with the constraint 42.

[0150] In other examples, the constraint 42 can be bonded to the air guide shroud 30.

[0151] Figure 6 yes Figure 3A A magnified structural diagram at point C.

[0152] In some implementations, the guide channel may be constructed by hollowing out a wall of the air guide bracket 20 in the second direction. (See reference...) Figure 6 In the example shown, the guide groove is formed by hollowing out the second plate 20b wall of the air guide bracket 20.

[0153] In some examples, the width w2 of the guide groove is greater than the dimension of the constraint 42 along the same direction, so that the constraint 42 can stably fit with the guide groove. Here, the width of the guide groove can be understood as the dimension of the guide groove along a third direction, which intersects with the first direction.

[0154] Figure 7 This is a schematic diagram of the structure of a constraint component in a server provided in an embodiment of this application.

[0155] Reference Figure 7 As shown, in some embodiments, the constraint member 42 includes a first part 421 and a second part 422. The outer diameter w1 of the first part 421 is larger than the width w2 of the guide groove. The second part 422 passes through the guide groove and is fixedly connected to the air guide shroud 30, so that the constraint member 42 passes through the guide groove. Therefore, the outer diameter w1 of the first part 421 is designed to be larger than the width w2 of the guide groove so that the first part 421 and the second part 422 can be located on opposite sides of the guide groove along the second direction, avoiding the problem of the constraint member 42 coming out of the guide groove due to external force or vibration, and improving the stability of the connection between the air guide shroud 30 and the air guide bracket 20.

[0156] In some examples, the guide groove is formed by hollowing out the wall of the air guide bracket 20 in the direction shown in T2, so the first part 421 and the second part 422 can be located on both sides of the guide groove in the direction shown in T2 (see Figure 2).

[0157] In some other examples, the guide groove is formed by a wall cutout of the air guide bracket 20 in the direction shown in T3, in which case the first part 421 and the second part 422 can be located on both sides of the guide groove in the direction shown in T3 (not shown).

[0158] In some examples, the constraint 42 can be a stepped screw or other structural member with a stepped structure. The specific type of constraint 42 is not limited in the embodiments of this application.

[0159] In some embodiments, the guide groove has a first groove and a second groove continuously arranged along its depth direction. The second part 422 of the constraint member 42 includes a first segment 4221 and a second segment 4222. The outer diameter of the first segment 4221 is different from the outer diameter of the second segment 4222. The first part 421 is used to be embedded in the first groove, the first segment 4221 is used to be embedded in the second groove, and the second segment 4222 is used to be fixedly connected to the air guide shroud 30. Thus, the outer diameter of the first segment 4221 matches the size of the second groove, and the outer diameter of the second segment 4222 is determined according to the strength of the air guide shroud 30, which improves the flexibility of the outer diameter configuration of the second part 422. While ensuring the stability of the fit between the guide groove and the constraint member 42, the structural strength of the air guide shroud 30 is also ensured.

[0160] Reference Figure 3B As shown, in some embodiments, the air guide shroud 30 is provided with a fastening hole 36, and the second section 4222 of the constraint member 42 passes through the fastening hole 36.

[0161] In some examples, the second segment 4222 of the constraint member 42 is interference-fitted into the fastening hole 36.

[0162] In some examples, the air guide structure 200 also includes an elastic ring 43, which is sandwiched between the second segment 4222 of the constraint member 42 and the fastening hole 36, thereby achieving an interference fit between the constraint member 42 and the fastening hole 36.

[0163] In some embodiments, the movement of the air guide shroud 30 relative to the air guide bracket 20 along the first direction can be achieved manually or automatically. This application embodiment does not impose specific limitations on whether it is achieved manually or automatically.

[0164] Figure 8A This is an exploded structural diagram of a wind-guiding structure in a server provided in an embodiment of this application; Figure 8B yes Figure 8A A magnified structural diagram of point D in the structure shown.

[0165] Reference Figure 8A and Figure 8BAs shown, in some embodiments, the air guide structure 200 further includes an elastic element 50, which is elastically connected between the air guide bracket 20 and the air guide shroud 30 along a first direction, and can be selectively in a compressed state or a free state. Correspondingly, the first plate 20a of the air guide bracket 20 is connected to the back plate 1023 of the node 102. When the elastic element 50 is switched to the free state, the air guide shroud 30 pops out relative to the air guide bracket 20, causing the air guide structure 200 to be in an extended state. When the elastic element 50 is switched to the compressed state, the air guide shroud 30 contracts relative to the air guide bracket 20, causing the air guide structure 200 to be in a contracted state.

[0166] Combination Figure 2B and Figure 5A As shown, in the above scheme, during the insertion of node 102 into the accommodating cavity 1011, the tail end of the air guide shroud 30 along the first direction will abut against the end face of the wall forming the air-cooled zone 104 in the first direction (see...). Figure 2B Due to the interaction between the tail end of the air guide shroud 30 and its end face, and since the chassis 101 remains stationary, the air guide shroud 30 is forced to move into the first air guide duct 21. Correspondingly, the elastic member 50, being elastically connected between the air guide bracket 20 and the air guide shroud 30 along the first direction, is compressed as the air guide shroud 30 moves into the first air guide duct 21, thus remaining in a compressed state. Therefore, when the node 102 is loaded into the receiving cavity 1011, the tail end of the air guide shroud 30 abuts against the end face of the wall forming the air-cooled zone 104 in the first direction, and the spring is in a compressed state. Additionally, the constraint member 42 moves along the guide groove to its first limit position.

[0167] Combination Figure 5B and 5C As shown, during the process of extracting node 102 from the accommodating cavity 1011, the tail end of the air guide shroud 30 gradually moves away from the end face of the wall forming the air-cooled zone 104 in the first direction. Since the air guide shroud no longer interacts with this end face, the compressed elastic member 50 will attempt to return to a free state based on its own elasticity characteristics. When the distance between the air guide shroud and the end face is small, the elastic member 50 partially elongates from the compressed position. At this time, the constraint member 42 will move along the guide groove from the first extreme position to the second extreme position (see...). Figure 5B As the distance between the air guide shroud and the end face increases until the elastic element 50 returns to its free state, the air guide shroud 30 is ejected outward from the first air guide channel 21 under the action of the elastic element 50, causing the air guide structure 200 to be in an extended state. Therefore, when the node 102 is pulled out of the receiving cavity 1011, the spring is in a free state. Additionally, the constraint member 42 will move along the guide groove to the second limit position (see...). Figure 5C ).

[0168] According to an embodiment of this application, a server 100 is provided: by introducing an elastic element 50 and configuring the elastic element 50 to be elastically connected between the air guide bracket 20 and the air guide cover 30 along a first direction, when the node 102 is loaded into the receiving cavity 1011, the air guide cover 30 is squeezed by the inner wall of the receiving cavity 1011, causing the elastic element 50 to be in a compressed state, and the air guide structure 200 as a whole is in a contracted state, resulting in a compact structure; when the node 102 is pulled out of the receiving cavity 1011 for maintenance, the elastic element 50 returns to a free state, causing the air guide cover 30 to pop out from the air guide bracket 20 and then be in an extended state. Thus, the air guide channel can be automatically established and maintained during hot-swapping, continuously guiding the air-cooled airflow through the interior of the node 102, achieving effective heat dissipation for electronic devices, significantly extending the time window for safe maintenance operations, and further improving the automation level and operational reliability of the hot-swapping function.

[0169] In some embodiments, the elastic element 50 can be an elastic structure such as a spring or an elastic block. This application does not limit the type of elastic element 50.

[0170] Figure 9A This is a second exploded structural diagram of a wind-guiding structure in a server provided in an embodiment of this application; Figure 9B yes Figure 9A A magnified structural diagram of point E in the structure shown. Figure 9A Compared to the air guide bracket in the middle Figure 8A The air guide bracket in the middle is rotated at an angle around a third direction.

[0171] Combination Figure 9A and Figure 9B As shown, in some embodiments, the air guide shroud 30 is sleeved on the air guide bracket 20 along the first direction. The air guide structure 200 also includes a first base plate 23 and a second base plate 24: the first base plate 23 is disposed on the inner side of the air guide bracket 20, and one end of the elastic member 50 is connected to the first base plate 23; the second base plate 24 is disposed on the air guide shroud 30 and is spaced apart from the first base plate 23 along the first direction, and the other end of the elastic member 50 abuts against the second base plate 24. Thus, a stable and controllable elastic connection relationship is formed between the air guide bracket 20 and the air guide shroud 30.

[0172] Here, the inner side of the air guide bracket 20 can be understood as the side of the air guide bracket 20 facing the air guide cover 30.

[0173] Reference Figure 8B As shown, the third plate 30b of the air guide shroud 30 is recessed inward (which can be understood as recessed towards the side forming the second air guide duct 31) to form a groove 35. The second base plate 24 is connected to the bottom of the groove 35, serving as the connection base for the other end of the elastic member 50.

[0174] In some examples, the second base plate 24 is recessed inward on one side of the surface facing the first base plate 23 along the first direction to form a spiral groove, and the other end of the elastic member 50 can be embedded in the spiral groove so that the other end of the elastic member 50 abuts against the second base plate 24.

[0175] In other examples, the other end of the elastic element 50 may be welded to the side surface of the second base plate 24 facing the first base plate 23 in the first direction.

[0176] It should be noted that the embodiments of this application do not limit the manner in which the elastic member 50 abuts against the second base plate 24.

[0177] Reference Figure 9B As shown, the second plate 20b of the air guide bracket 20 in the second direction protrudes inward to form a first base plate 23, which serves as the connection base for one end of the elastic member 50. The first base plate 23 is located within the groove 35.

[0178] Similarly, in some examples, the surface of the first base plate 23 facing the second base plate 24 in the first direction is recessed inward to form a spiral groove, and one end of the elastic member 50 is embedded in the spiral groove so that one end of the elastic member 50 abuts against the first base plate 23.

[0179] In other examples, one end of the elastic element 50 is welded to the side surface of the first base plate 23 facing the second base plate 24 in a first direction.

[0180] It should be noted that the embodiments of this application do not limit the manner in which the elastic member 50 abuts against the first base plate 23.

[0181] In some implementations, the first base plate 23 can be integrally formed from the air guide bracket 20.

[0182] Reference Figure 8A As shown, in some examples, the air guide bracket 20 is cut and folded inside to obtain the first base plate 23, and a notch 26 is formed at the cut.

[0183] Therefore, by providing a groove extending along the first direction on the air guide shroud 30, and accommodating both the second base plate 24 and the first base plate 23 within the groove, the elastic element 50 can be compactly arranged within the confined space between the air guide shroud 30 and the air guide bracket 20. This improves the utilization rate of the internal space of the air guide structure 200 and avoids interference from additional protrusions or exposed parts on the telescopic movement. Furthermore, the groove 35 can comprehensively cover and guide the formation of the first base plate 23, the second base plate 24, and the elastic element 50.

[0184] In some embodiments, when node 102 is loaded in the receiving cavity 1011, the distance between the first base plate 23 and the second base plate 24 corresponds to the distance of the elastic member 50 in the compressed state. Correspondingly, when node 102 is pulled out of the receiving cavity 1011, the distance between the first base plate 23 and the second base plate 24 corresponds to the distance of the elastic member 50 in the free state.

[0185] Reference Figure 8B As shown, in some embodiments, the air guide structure 200 further includes a first guide pin 51, which is connected to the side of the first base plate 23 facing the second base plate 24. The elastic element 50 is sleeved on the first guide pin 51. Thus, the first guide pin 51 provides axial guidance and radial limiting for the compression and rebound process of the elastic element 50, effectively preventing the elastic element 50 from skewing or becoming unstable during extension and retraction, ensuring the extension and retraction accuracy and consistency of the air guide cover 30 relative to the air guide bracket 20. Therefore, during hot-plugging operations at node 102, the air guide cover 30 can more reliably extend into the receiving cavity 1011, thereby improving the overall reliability of the hot-plugging maintenance process.

[0186] Combination Figure 9B As shown, in some embodiments, the first base plate 23 is provided with a first connecting hole 231 extending in a first direction.

[0187] In some examples, the first guide pin 51 is fixedly connected to the first base plate 23 by passing a first fastener through the first connecting hole 231 and extending into the first guide pin 51.

[0188] In other examples, the first guide pin 51 is interference-fitted into the first connecting hole 231.

[0189] In some embodiments, the profile dimension of the first guide pin 51 in the first direction is slightly smaller than the inner diameter dimension of the elastic member 50 in the first direction, so that the frictional force experienced by the elastic member 50 when it is compressed or rebounds in the first direction is smaller.

[0190] Combination Figure 8B As shown, in some embodiments, the air guide structure 200 further includes a second guide pin 52, which is connected to the side of the second base plate 24 facing the first base plate 23. The elastic element 50 is sleeved on the second guide pin 52. Thus, the second guide pin 52 provides guidance and limitation for the compression and rebound process of the elastic element 50, effectively preventing the elastic element 50 from deflecting or becoming unstable during the extension and retraction process, ensuring the extension and retraction accuracy and consistency of the air guide cover 30 relative to the air guide bracket 20, thereby improving the overall reliability of the hot-swappable maintenance process.

[0191] In some examples, the second guide pin 52 can be fixedly connected to the second base plate 24 by screws.

[0192] In other examples, the second base plate 24 is provided with a second connecting hole (not shown) extending in the first direction, and the second guide pin 52 can be interference-fitted into the second base plate 24.

[0193] The above embodiments are merely specific embodiments of this application and are not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made based on the technical solution of this application should be included within the scope of protection of this application.
