A wind deflector and a server

Abstract

This application discloses an air guide shroud and a server, relating to the field of server air guide structure technology. It includes an air guide plate, which is positioned on the side of the server's memory module away from the memory slot. The air guide plate has at least one movable first deflector at its air inlet end and at least one movable second deflector at its air outlet end. The first and second deflectors are positioned opposite each other to correspond to the two ends of a memory slot. Both the first and second deflectors can switch between two positions to block or avoid the corresponding memory slot. By switching the positions of the first and second deflectors, airflow to areas without installed memory is prevented from being lost or consumed, thus preventing hot air recirculation. This allows for precise airflow guidance for different memory configurations, solving the technical problem of partial loss of cool airflow when the memory slot is empty. This achieves the technical effect of improving the air guide shroud's airflow capacity and heat dissipation.

Description

Technical Field

[0001] This invention relates to the field of server airflow structure technology, and more specifically, to an airflow shroud and a server. Background Technology

[0002] As servers evolve towards higher computing power, the power consumption and heat generation of memory continue to increase. Therefore, the heat dissipation efficiency of the server cooling system is crucial for the stable operation of the server. As a core airflow guiding component within the server chassis, the air duct's function is to guide the flow of cool air, forcing it through heat-generating areas such as memory, and preventing insufficient heat dissipation caused by dispersed airflow.

[0003] However, in related technologies, server memory configuration is flexible. For example, due to business needs, some memory slots may be left empty. In this case, under the guidance of the air duct, the cold air will be lost directly from the empty area without passing through the heat-generating components, resulting in a reduction in the effective airflow of the inserted memory modules and processors, which will cause the temperature of the core components such as the inserted memory modules and processors to rise and affect server performance.

[0004] In conclusion, how to improve the air guiding capacity and heat dissipation effect of the air guide shroud is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] This application provides an air guide shroud to at least solve the technical problem of partial loss of cool airflow when memory slots are idle in related technologies.

[0006] This application provides an air guide cover, including: an air guide plate, which is used to be disposed on the side of a server's memory module away from the memory slot. The air guide plate has at least one movable first deflector at its air inlet end and at least one movable second deflector at its air outlet end. The first deflector and the second deflector are disposed opposite to each other to correspond to the two ends of a memory slot. Both the first deflector and the second deflector can switch between two positions to block or avoid the corresponding memory slot.

[0007] This application also provides a server, including the aforementioned air guide cover.

[0008] This application utilizes movable first and second air deflectors, allowing their positions to be switched according to different memory configurations. When no memory modules are installed in the memory slots, the first and second air deflectors prevent airflow from flowing into the un-installed memory areas, thus preventing loss and heat recirculation. This enables precise airflow guidance for different memory configurations, improving the airflow guidance and anti-backflow capabilities of the air deflector, allowing more cool air to be effectively utilized. This helps reduce the temperature of the memory modules and the nearby processor, ensuring the reliability of memory and processor operation, avoiding frequency throttling protection, and improving heat dissipation capacity and efficiency. Furthermore, this solution is adaptable to any memory combination configuration, offering high versatility. Attached Figure Description

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

[0029] 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.

[0030] Please refer to Figure 1 and Figure 2 This invention provides an air guide cover, including an air guide plate 1. The air guide plate 1 is used to be disposed on the side of the memory module 10 of the server away from the memory slot 20. The air inlet end of the air guide plate 1 is provided with at least one movable first air deflector 2, and the air outlet end of the air guide plate 1 is provided with at least one movable second air deflector 3. One first air deflector 2 and one second air deflector 3 are disposed opposite to each other to correspond to the two ends of a memory slot 20. Both the first air deflector 2 and the second air deflector 3 can be switched between two positions to block or avoid the corresponding memory slot 20.

[0031] Understandably, when this air guide is applied to a server, the air guide plate 1 is installed on the side of the server's memory module 10 away from the memory slot 20. The side of the air guide plate 1 facing the memory module 10 is the air guide surface, so as to guide the cold air through the memory slot 20 to dissipate heat from the memory module 10 inserted in the memory slot 20.

[0032] This embodiment features a movable first baffle 2 at the air inlet of the air guide plate 1, allowing the first baffle 2 to switch between two positions. By switching the position of the first baffle 2, it can either block or avoid the corresponding memory slot 20. For example, the first baffle 2 can switch between a first position and a second position. When the first baffle 2 is in the first position, it avoids the memory slot 20; when the first baffle 2 is in the second position, it blocks the memory slot 20. Thus, the position of the first baffle 2 can be determined based on whether a memory module 10 is inserted into the memory slot 20. When a memory module 10 is inserted into memory slot 20, the first air deflector 2 is in the first position. In this position, the first air deflector 2 avoids the corresponding memory slot 20, allowing airflow to flow smoothly into the memory slot 20 with the memory module 10 inserted, thus dissipating heat from the memory module 10. When no memory module 10 is inserted into memory slot 20, the first air deflector 2 is in the second position. In this position, the first air deflector 2 blocks the memory slot 20 without a memory module 10 inserted, preventing airflow into the memory slot 20 without a memory module 10 inserted. This avoids the loss and consumption of cool air in the memory slot 20 without a memory module 10 inserted, allowing more cool air to enter the memory slot 20 with a memory module 10 inserted, thus improving heat dissipation efficiency.

[0033] Similarly, in this embodiment, a movable second baffle 3 is provided at the air outlet of the air guide plate 1, and the second baffle 3 can switch between two positions. By switching the position of the second baffle 3, the second baffle 3 can either block or avoid the corresponding memory slot 20. For example, the second baffle 3 can switch between a third position and a fourth position. When the second baffle 3 is in the third position, the second baffle 3 can avoid the memory slot 20. When the second baffle 3 is in the fourth position, the first baffle 2 can block the memory slot 20. Thus, depending on whether the memory slot 20 is blocked... Insert the memory module 10 and determine whether the second fan baffle 3 is in the third or fourth position. When the memory module 10 is inserted into the memory slot 20, the second fan baffle 3 is in the third position. At this time, the second fan baffle 3 avoids the corresponding memory slot 20 so that airflow can flow out from the memory slot 20 with the memory module 10 inserted, carrying away the heat of the memory module 10. When the memory slot 20 is not inserted with the memory module 10, the second fan baffle 3 is in the fourth position. At this time, the second fan baffle 3 blocks the memory slot 20 without the memory module 10 inserted, preventing the hot air from flowing back from the exhaust end, so as to ensure the working temperature of the inserted memory module 10.

[0034] Therefore, this embodiment of the invention, by setting movable first and second baffles 2 and 3, allows the positions of the first and second baffles 2 and 3 to be switched according to different memory configurations. This prevents airflow from flowing to areas where no memory is installed, thus preventing loss and consumption, and also prevents hot air backflow. This allows for precise airflow guidance for different memory configurations, improving the airflow guidance and anti-backflow capabilities of the air shroud, enabling more cool air to be effectively utilized. This helps reduce the temperature of the memory module 10 and the nearby processor, ensuring the reliability of memory and processor operation, avoiding frequency throttling protection, and improving heat dissipation capacity and efficiency. Moreover, this solution is adaptable to any memory combination configuration, exhibiting high versatility.

[0035] It is understandable that the width of a single first air deflector 2 and the width of a single second air deflector 3 are approximately equal to the width of a single memory slot 20, and the length of a single first air deflector 2 and the length of a single second air deflector 3 are at least able to cover the airflow channel area at the air inlet and air outlet of the memory slot 20, so as to play a good role in shielding the memory slot 20.

[0036] Additionally, please refer to Figure 3 and Figure 4To prevent accidental operation that could cause the first wind deflector 2 and / or the second wind deflector 3 to be positioned in a way that obstructs the memory slot 20 when a memory module 10 is inserted into the memory slot 20, in some embodiments, both the first wind deflector 2 and the second wind deflector 3 are provided with a first protrusion 21. The first protrusion 21 is used to interfere with the memory module 10 in the corresponding memory slot 20, so that the first wind deflector 2 and the second wind deflector 3 cannot be positioned in a way that obstructs the corresponding memory slot 20 when a memory module 10 is inserted into the memory slot 20.

[0037] In other words, this embodiment provides a first protrusion 21 on the first air deflector 2 and the second air deflector 3 to prevent mistaken operation. It can be understood that the first protrusion 21 faces the memory slot 20. When the first air deflector 2 and / or the second air deflector 3 corresponding to the memory slot 20 with the memory stick 10 inserted is accidentally moved to a position that blocks the memory slot 20 (such as the second position and the fourth position mentioned above), the first protrusion 21 will come into contact with the inserted memory stick 10 and cause interference, so that the first air deflector 2 and / or the second air deflector 3 is lifted up and cannot reach the position that blocks the memory slot 20 (such as the second position and the fourth position mentioned above). At this time, the first air deflector 2 and / or the second air deflector 3 can be moved to a position that avoids the memory slot 20 (such as the first position and the third position mentioned above) to avoid blocking the heat dissipation airflow of the inserted memory stick 10. Understandably, the first protrusion 21 only restricts the first and second air deflectors 2 and 3 from obstructing the memory slot 20 when the memory module 10 is present in the memory slot 20. When no memory module 10 is installed in the memory slot 20, the first protrusion 21 can extend into the memory slot 20 without interference. Therefore, it ensures that the first and second air deflectors 2 and 3 are in a position obstructing the memory slot 20 when no memory module 10 is installed. This solution avoids accidentally obstructing the installed memory module 10, ensuring the reliability of heat dissipation for the memory module 10 and improving operational safety.

[0038] Additionally, it should be noted that this embodiment does not limit the specific location of the first protrusion 21, as long as the first protrusion 21 can interfere with the corresponding inserted memory module 10. For example, the first protrusion 21 is located in the middle of the side of the first baffle 2 and the second baffle 3 facing the memory slot 20, which helps to ensure that the first protrusion 21 can interfere with the corresponding inserted memory module 10.

[0039] In addition, this embodiment does not limit the specific structure of the first protrusion 21. For example, the first protrusion 21 can be a protrusion, a tab, or a plate that protrudes from the first wind deflector 2 and the second wind deflector 3 on the side facing the memory slot 20, respectively.

[0040] Additionally, please refer to Figure 5In order to allow the cool air to enter the memory module 10 and the processor in the vicinity more smoothly, in some embodiments, the air duct also includes a guide block 4. The guide block 4 is detachably connected to the first air deflector 2 located at the position of blocking the corresponding memory slot 20. The guide block 4 has an inclined air guiding surface 41 to guide the air to the memory slot 20 where the memory module 10 is inserted.

[0041] It is understandable that the inclined air guide surface 41 is tilted toward the location of the memory slot 20 where the memory module 10 is installed, so as to use the inclined air guide surface 41 of the guide block 4 to guide the cold air through the area where the memory module is installed and the processor area, etc., to further reduce airflow loss and improve the airflow effect and heat dissipation efficiency.

[0042] It should be noted that the guide block 4 can have different sizes to fit the overall width of the first baffle strip 2 located at the position of obstructing the memory slot 20. That is, when the number of first baffle strips 2 located at the position of obstructing the memory slot 20 is small, a smaller guide block 4 can be used; when the number of first baffle strips 2 located at the position of obstructing the memory slot 20 is large, a larger guide block 4 can be used. In addition, the inclined air guide surface 41 can also have different inclination angles to balance stable air guidance and high-efficiency air guidance.

[0043] Additionally, please refer to Figure 3 and Figure 5 In order to facilitate the installation of the guide block 4 and the first wind deflector 2, in some embodiments, the first wind deflector 2 is provided with a fixing hole 22, and the guide block 4 is connected to the fixing hole 22 through a pin.

[0044] In other words, in this embodiment, the guide block 4 and the first windbreak strip 2 are fixed by inserting the insert into the fixing hole 22. This installation structure is simple and easy to install.

[0045] In addition, such as Figure 5 As shown, in order to facilitate the disassembly and assembly of the guide block 4, in some embodiments, the guide block 4 is provided with a disassembly and assembly part 42, which is used to assist in the disassembly and assembly of the guide block 4.

[0046] In other words, this embodiment provides a disassembly / removal part 42 on the guide block 4 so that when disassembling or assembling the guide block 4, external force can be applied to the guide block 4 through the disassembly / removal part 42, making it easier to grip the guide block 4 and to remove it by applying force. It should be noted that this embodiment does not limit the specific structure of the disassembly / removal part 42; for example, the disassembly / removal part 42 can be a groove or protrusion provided in the guide block 4. Furthermore, it is understood that the disassembly / removal part 42 is located at the position of the non-inclined air guide surface 41 of the guide block 4.

[0047] In addition, it should be noted that the above embodiments do not limit the specific installation structure of the first wind deflector 2 and the second wind deflector 3, as long as the first wind deflector 2 and the second wind deflector 3 can be movable and can be switched between two positions respectively.

[0048] Please refer to Figure 7 and Figure 8 In some embodiments, the air inlet end of the air guide plate 1 is provided with a first mounting seat 5, and the first baffle 2 is rotatably mounted on the first mounting seat 5; the air outlet end of the air guide plate 1 is provided with a second mounting seat 6, and the second baffle 3 is rotatably mounted on the second mounting seat 6.

[0049] In other words, this embodiment achieves the installation of the first wind deflector 2 and the second wind deflector 3 on the air guide plate 1 by rotational installation, allowing the first wind deflector 2 and the second wind deflector 3 to rotate. This enables the first wind deflector 2 to switch between a first position and a second position, and the second wind deflector 3 to switch between a third position and a fourth position. This movement method is simple and easy to implement. For example, the first mounting base 5 has a first mounting hole, and the first wind deflector 2 has a first rotating shaft 24, which engages with the shaft hole of the first mounting hole and is rotatably connected to it. The second mounting base 6 has a second mounting hole, and the second wind deflector 3 has a second rotating shaft, which engages with the shaft hole of the second mounting hole and is rotatably connected to it.

[0050] Furthermore, such as Figure 7 and Figure 8 As shown, in order to enable the first wind deflector 2 to be positioned in the first or second position, and the second wind deflector 3 to be positioned in the third or fourth position, in some embodiments, the first mounting base 5 is provided with a first limiting part 511 and a second limiting part 521, and the first wind deflector 2 is provided with a third limiting part 23. When the third limiting part 23 is connected with the first limiting part 511, the first wind deflector 2 is used to block the corresponding memory slot 20. When the third limiting part 23 is connected with the second limiting part 521, the first wind deflector 2 is used to avoid the corresponding memory slot 20. The second mounting base 6 is provided with a fourth limiting part 611 and a fifth limiting part 621, and the second wind deflector 3 is provided with a sixth limiting part. When the sixth limiting part is connected with the fourth limiting part 611, the second wind deflector 3 is used to block the corresponding memory slot 20. When the sixth limiting part is connected with the fifth limiting part 621, the second wind deflector 3 is used to avoid the corresponding memory slot 20.

[0051] In other words, this embodiment achieves the switching of the first wind deflector 2 between a first position and a second position by allowing the third limiting part 23 to switchably connect with the first limiting part 511 and the second limiting part 521. When it is necessary for the first wind deflector 2 to block the air inlet of the corresponding memory slot 20, the first wind deflector 2 is rotated to the second position. At this time, the third limiting part 23 is connected with the second limiting part 521, keeping the first wind deflector 2 in the second position to ensure the reliability of the first wind deflector 2 in blocking the corresponding memory slot 20. When it is necessary for the first wind deflector 2 to avoid the air inlet of the corresponding memory slot 20, the first wind deflector 2 is rotated to the first position. At this time, the third limiting part 23 is connected with the first limiting part 511, keeping the first wind deflector 2 in the first position to ensure that the first wind deflector 2 maintains the state of avoiding the corresponding memory slot 20.

[0052] Similarly, in this embodiment, the second baffle 3 can be switched between the third and fourth positions by allowing the sixth limiting part to switchably connect with the third limiting part 23 and the fourth limiting part 611. When it is necessary for the second baffle 3 to block the air outlet of the corresponding memory slot 20, the second baffle 3 is rotated to the fourth position. At this time, the sixth limiting part connects with the fifth limiting part 621, keeping the second baffle 3 in the fourth position to ensure the reliability of the second baffle 3 blocking the corresponding memory slot 20. When it is necessary for the second baffle 3 to avoid the air outlet of the corresponding memory slot 20, the second baffle 3 is rotated to the third position. At this time, the sixth limiting part connects with the fourth limiting part 611, keeping the second baffle 3 in the third position to ensure that the second baffle 3 maintains the state of avoiding the corresponding memory slot 20.

[0053] It should be noted that this embodiment does not limit the specific structure of the first limiting part 511, the second limiting part 521, the third limiting part 23, the fourth limiting part 611, the fifth limiting part 621, and the sixth limiting part. As long as the third limiting part 23 can be switched to cooperate with the first limiting part 511 and the second limiting part 521, and the sixth limiting part can be switched to cooperate with the third limiting part 23 and the fourth limiting part 611.

[0054] like Figure 7 , Figure 8 and Figure 9 As shown, in some embodiments, the first limiting part 511, the second limiting part 521, the fourth limiting part 611 and the fifth limiting part 621 are limiting holes, and the third limiting part 23 and the sixth limiting part are limiting posts.

[0055] In other words, this embodiment achieves the switching connection between the first windshield strip 2 and the first mounting base 5 at two positions through the cooperation of the limiting post and the limiting hole, so that the first windshield strip 2 can be switched to a first position and a second position; for example, the first limiting part 511 is a first limiting hole provided in the first mounting base 5, the second limiting part 521 is a second limiting hole provided in the first mounting base 5, and the third limiting part 23 is a first limiting post provided in the first windshield strip 2. When it is necessary to switch the first windshield strip 2 to avoid the memory slot 20 When the first windshield 2 is in the first position, rotate the first windshield 2 so that the first limiting post of the first windshield 2 is aligned with the first limiting hole of the first mounting base 5, and insert the first limiting post into the first limiting hole to fix the first windshield 2 in the first position; when it is necessary to switch the first windshield 2 to the position of blocking the memory slot 20, rotate the first windshield 2 so that the first limiting post of the first windshield 2 is aligned with the second limiting hole of the first mounting base 5, and insert the first limiting post into the second limiting hole to fix the first windshield 2 in the second position. Similarly, this embodiment achieves the switching connection between the second wind deflector 3 and the second mounting base 6 through the cooperation of the limiting post and the limiting hole, so that the second wind deflector 3 can be switched between the third position and the fourth position. For example, the fourth limiting part 611 is the third limiting hole provided in the second mounting base 6, the fifth limiting part 621 is the fourth limiting hole provided in the second mounting base 6, and the sixth limiting part is the second limiting post provided in the second wind deflector 3. When it is necessary to switch the second wind deflector 3 to the position that avoids the memory slot 20, When in the first position, rotate the second baffle strip 3 so that its second limiting post aligns with the third limiting hole of the second mounting base 6, allowing the second limiting post to be inserted into the third limiting hole, thus fixing the second baffle strip 3 in the third position. When it is necessary to switch the second baffle strip 3 to the position of blocking the memory slot 20, rotate the second baffle strip 3 so that its second limiting post aligns with the fourth limiting hole of the second mounting base 6, allowing the second limiting post to be inserted into the fourth limiting hole, thus fixing the second baffle strip 3 in the fourth position. This connection structure is simple, easy to operate, and tool-free, with strong usability and versatility. Simply moving the first baffle strip 2 and the second baffle strip 3 by hand can achieve the operation of blocking or avoiding the corresponding memory slot 20. To facilitate the cooperation between the limiting post and the limiting hole, the first baffle strip 2 and the second baffle strip 3 can be made of plastic.

[0056] It should be noted that the specific structure of the first mounting base 5 and the second mounting base 6 in the above embodiments is not limited, as long as the first wind deflector 2 and the second wind deflector 3 can be rotated and installed respectively, and the first wind deflector 2 and the second wind deflector 3 can be switched between two positions respectively.

[0057] Furthermore, such as Figure 7 and Figure 8As shown, in some embodiments, the air inlet end of the air guide plate 1 is connected to an inclined baffle 7. The first mounting base 5 includes a first limiting plate 51 and a second limiting plate 52. The first limiting plate 51 and the second limiting plate 52 form a V-shaped structure. The first limiting plate 51 is parallel to the baffle 7, and the second limiting plate 52 is perpendicular to the air guide plate 1. When the first wind deflector 2 is connected to the first limiting plate 51, the first wind deflector 2 is parallel to the baffle 7. When the first wind deflector 2 is connected to the second limiting plate 52, the first wind deflector 2 is perpendicular to the air guide plate 1 and extends to the side where the air guide surface of the air guide plate 1 is located.

[0058] In other words, such as Figure 3 and Figure 7 As shown, in this embodiment, a first mounting base 5 with a V-shaped structure is used, and a first limiting plate 51 and a second limiting plate 52 with a V-shaped structure are used to limit the two positions of the first wind deflector 2 (i.e., the first position and the second position). When the first wind deflector 2 is rotated to the first position, the first wind deflector 2 is connected to the first limiting plate 51. At this time, the first wind deflector 2 is parallel to the baffle 7 to avoid the corresponding memory slot 20. When the first wind deflector 2 is rotated to the second position, the first wind deflector 2 is connected to the second limiting plate 52. At this time, the first wind deflector 2 is perpendicular to the air guide plate 1 and extends to the side where the air guide surface of the air guide plate 1 is located to block the air inlet of the corresponding memory slot 20. In this design, when the first baffle 2 avoids the corresponding memory slot 20, it retracts to a position parallel to the baffle 7, preventing it from affecting the airflow direction of the cool air. This also results in a compact structure and saves space. When the first baffle 2 blocks the corresponding memory slot 20, it is perpendicular to the air guide plate 1 and extends towards the side of the air guide surface of the air guide plate 1, ensuring that the first baffle 2 fully blocks the air intake of the memory slot 20. This design is ingenious, compact, and avoids disrupting the airflow direction when the first baffle 2 avoids the memory slot 20.

[0059] In some embodiments, the second mounting base 6 includes a third limiting plate 61 and a fourth limiting plate 62, which form an L-shaped structure. The third limiting plate 61 is attached to the side of the air guide plate 1 away from its air guiding surface, and the fourth limiting plate 62 is perpendicular to the air guide plate 1. When the second baffle strip 3 is connected to the third limiting plate 61, the second baffle strip 3 is attached to the side of the air guide plate 1 away from its air guiding surface. When the second baffle strip 3 is connected to the fourth limiting plate 62, the second baffle strip 3 is perpendicular to the air guide plate 1 and extends to the side where the air guiding surface of the air guide plate 1 is located.

[0060] In other words, such as Figure 6 and Figure 8As shown, this embodiment uses an L-shaped second mounting base 6, and uses an L-shaped third limiting plate 61 and a fourth limiting plate 62 to define two positions (i.e., the third position and the fourth position) of the second baffle 3. When the second baffle 3 rotates to the third position, the second baffle 3 is connected to the third limiting plate 61. At this time, the second baffle 3 is attached to the side of the air guide plate 1 away from its air guide surface to avoid the corresponding memory slot 20. When the second baffle 3 rotates to the fourth position, the second baffle 3 is connected to the fourth limiting plate 62. At this time, the second baffle 3 is perpendicular to the air guide plate 1 and extends to the side where the air guide surface of the air guide plate 1 is located to block the air outlet of the corresponding memory slot 20. In this design, when the second baffle 3 avoids the corresponding memory slot 20, it retracts to the side of the air guide plate 1 away from its air guide surface. This prevents the first baffle 2 from affecting the airflow direction of the cold air, while also making the structure compact and saving space. When the second baffle 3 blocks the corresponding memory slot 20, it is perpendicular to the air guide plate 1 and extends to the side where the air guide surface of the air guide plate 1 is located, allowing the second baffle 3 to fully block the air intake of the memory slot 20. This design is ingenious, compact, and avoids disrupting the airflow direction when the second baffle 3 avoids the memory slot 20.

[0061] Furthermore, in some embodiments, the first limiting plate 51 is provided with the first limiting part 511 (such as the first limiting hole) as described above, the second limiting plate 52 is provided with the second limiting part 521 (such as the second limiting hole) as described above, and the first rotating shaft 24 is provided at the connection position of the first limiting plate 51 and the second limiting plate 52, with the first limiting part 511 (such as the first limiting hole) and the second limiting part 521 (such as the second limiting hole) located on both sides of the first rotating shaft 24 respectively.

[0062] In some embodiments, the third limiting plate 61 is provided with the fourth limiting part 611 (such as the third limiting hole) as described above, the fourth limiting plate 62 is provided with the fifth limiting part 621 (such as the fourth limiting hole) as described above, and the second rotating shaft is provided at the connection position of the third limiting plate 61 and the fourth limiting plate 62, with the fourth limiting part 611 (such as the third limiting hole) and the fifth limiting part 621 (such as the fourth limiting hole) located on both sides of the second rotating shaft respectively.

[0063] Furthermore, considering the simplicity of the structure and ease of processing, in some embodiments, the first wind deflector 2 and the second wind deflector 3 have the same structure. This solution allows for the interchangeable use of the first wind deflector 2 and the second wind deflector 3, offering strong versatility. During installation, there is no need to distinguish between the first wind deflector 2 and the second wind deflector 3, facilitating installation, maintenance, and management.

[0064] In addition, such as Figure 7 and Figure 8As shown, in some embodiments, there are at least two first mounting seats 5, all of which are spaced apart along the width direction of the air inlet end of the air guide plate 1, and a first baffle strip 2 is provided between any two adjacent first mounting seats 5; there are at least two second mounting seats 6, all of which are spaced apart along the width direction of the air outlet end of the air guide plate 1, and a second baffle strip 3 is provided between any two adjacent second mounting seats 6.

[0065] In other words, each side of a first wind deflector 2 is rotatably connected to two corresponding first mounting seats 5. Each first mounting seat 5 simultaneously supports the first wind deflectors 2 on both sides. This structure helps to reduce the number of first mounting seats 5, saving space, while providing stable and reliable support for the first wind deflectors 2. Similarly, each side of a second wind deflector 3 is rotatably connected to two corresponding second mounting seats 6. Each second mounting seat 6 simultaneously supports the second wind deflectors 3 on both sides. This structure helps to reduce the number of second mounting seats 6, saving space, while providing stable and reliable support for the second wind deflectors 3.

[0066] In addition, such as Figure 10 and Figure 12 As shown, in some embodiments, the air guide plate 1 is provided with a detachable connection structure.

[0067] It should be noted that the detachable connection structure is used to connect multiple air guide plates 1 when multiple air guide plates 1 are needed, thereby expanding the air guide plates 1 and adapting the air guide cover to various different needs. For example, an appropriate number of air guide plates 1 can be selected according to the memory configuration or processor configuration. Air guide plates 1 corresponding to memory modules 10 of different processors can be connected through the detachable connection structure. In this way, the air guide plates 1 can be spliced ​​according to the number of processors. This solution is compatible with processors and memory modules 10 with different configurations, has strong versatility, and helps to reduce the size of the air guide cover and reduce the cost of air guide cover molds.

[0068] It should be noted that this embodiment does not limit the specific structure of the detachable connection structure, as long as different air guide plates 1 can be connected through the detachable connection structure.

[0069] like Figure 14 As shown, in some embodiments, the number of air guide plates 1 is at least two, and the detachable connection structure includes a first detachable connection structure 11 and a second detachable connection structure 12. The two different air guide plates 1 are detachably connected through the first detachable connection structure 11 and the second detachable connection structure 12.

[0070] It is understood that the air guide plate 1 is provided with a first detachable connection structure 11 and / or a second detachable connection structure 12. The first detachable connection structure 11 and the second detachable connection structure 12 are mating structures that can be detachably connected. One of two different air guide plates 1 is provided with the first detachable connection structure 11, and the other is provided with the second detachable connection structure 12. The two different air guide plates 1 are detachably connected through the first detachable connection structure 11 and the second detachable connection structure. For example, multiple air guide plates 1 are arranged side by side, and at least two air guide plates 1 are detachably connected through the first detachable connection structure 11 and the second detachable connection structure.

[0071] It should be noted that this embodiment does not limit the specific structure of the first detachable connection structure 11 and the second detachable connection structure 12, as long as the detachable connection between the first detachable connection structure 11 and the second detachable connection structure 12 can be achieved.

[0072] In some embodiments, the first detachable connection structure 11 and the second detachable connection structure 12 of the different air guide plates 1 are slidably fitted together.

[0073] In other words, this embodiment achieves the connection of the first detachable connecting structure 11 and the second detachable connecting structure 12 by sliding fit. Thus, when assembling different air guide plates 1, it is only necessary to align and slide the first detachable connecting structure 11 and the second detachable connecting structure 12 until the first detachable connecting structure 11 and the second detachable connecting structure 12 are completely fitted together.

[0074] It is understandable that one of the first detachable connection structure 11 and the second detachable connection structure 12 is a groove (e.g., Figure 10 and Figure 11 As shown), the other is a boss (such as...). Figure 12 and Figure 13 As shown in the diagram, during installation, the boss is fitted into the groove. It should be noted that one side of the groove has an opening for the boss to slide in, and the groove and the boss have a mutually engaging limiting structure to prevent them from separating in a predetermined direction.

[0075] For example, the first detachable connection structure 11 is a T-shaped groove, an L-shaped groove, or a trapezoidal groove, etc., and correspondingly, the second detachable connection structure 12 is a T-shaped boss, an L-shaped boss, or a trapezoidal boss; the T-shaped boss cooperates with the T-shaped groove for limiting, the L-shaped boss cooperates with the L-shaped groove for limiting, and the trapezoidal boss cooperates with the trapezoidal groove for limiting. It can be understood that one side of the T-shaped groove, L-shaped groove, or trapezoidal groove has an opening for the T-shaped boss, L-shaped boss, or trapezoidal boss to slide into it accordingly, and the end of the T-shaped groove, L-shaped groove, or trapezoidal groove opposite to the opening has a groove bottom for limiting the sliding stroke. After the T-shaped boss cooperates with the T-shaped groove, the L-shaped boss with the L-shaped groove, and the trapezoidal boss with the trapezoidal groove for limiting, the two air guide plates 1 cannot be separated along the direction perpendicular to the installation direction. Of course, in other embodiments, the first detachable connection structure 11 can also be a shaped groove, and the second detachable connection structure 12 can also be a shaped boss, as long as the shaped boss can slide and fit into the shaped groove. In addition, it should be noted that this embodiment does not specifically limit the opening direction of the groove (such as the opening direction of a T-shaped groove, L-shaped groove, trapezoidal groove, or shaped groove). For example, the opening direction of the groove (such as the opening direction of a T-shaped groove, L-shaped groove, trapezoidal groove, or shaped groove) can be upward, forward, or backward. When the opening direction of the groove (such as the opening direction of a T-shaped groove, L-shaped groove, trapezoidal groove, or shaped groove) is upward, the two air guide plates 1 are vertically offset and slidably fitted together; when the opening direction of the groove (such as the opening direction of a T-shaped groove, L-shaped groove, trapezoidal groove, or shaped groove) is forward or backward, the two air guide plates 1 are horizontally offset and slidably fitted together.

[0076] In addition, the first detachable connection structure 11 and the second detachable connection structure 12 of different air guide plates 1 can also be connected by snap-fit. That is, the first detachable connection structure 11 and the second detachable connection structure 12 are snap-fit ​​structures. For example, one of the first detachable connection structure 11 and the second detachable connection structure 12 is a slot and the other is a buckle. The connection of different air guide plates 1 is realized by the snap-fit ​​and the slot engaging.

[0077] In addition, such as Figure 10 As shown, in order to facilitate the smooth guidance of cold air to the air guide surface of the air guide plate 1, in some embodiments, the air inlet end of the air guide plate 1 is connected to a baffle 7, which extends toward the side of the air guide plate 1 away from the memory module 10.

[0078] In other words, this embodiment uses a baffle 7 at the air inlet of the air guide plate 1 to block the airflow from flowing to the non-air guide side of the air guide plate 1. When the cold airflow reaches the air inlet of the air guide plate 1, the baffle 7 stops the airflow, causing it to change direction and flow towards the air guide surface of the air guide plate 1 (i.e., the side of the air guide plate 1 facing the memory module 10). This allows more cold air to flow to the memory module 10, effectively dissipating heat. This solution improves the effective utilization of cold airflow, reduces airflow loss, and enhances heat dissipation efficiency and effect.

[0079] It should be noted that the baffle 7 can be set perpendicular to the air guide plate 1 or tilted relative to the air guide plate 1, as long as it can promote the airflow to change direction and better flow to the air guide surface of the air guide plate 1.

[0080] Furthermore, such as Figure 10 As shown, in some embodiments, the baffle 7 is inclined so that the angle between the baffle 7 and the air guide plate 1 is obtuse.

[0081] It is understandable that the angle between the baffle 7 and the air guide plate 1 is obtuse, that is, the angle between the extension lines of the baffle 7 and the air guide plate 1 towards the air inlet is acute. In this way, the airflow can more easily enter the air guide surface of the air guide plate 1 along the inclined surface of the baffle 7, thereby improving the air guiding effect.

[0082] It should be noted that the tilt angle of the baffle 7 is not limited in this embodiment. It can be understood that the larger the tilt angle of the baffle 7 relative to the air guide plate 1, the more conducive it is to the flow of cold air to the air guide surface of the air guide plate 1. However, in order to ensure that the baffle 7 has a suitable height, the larger the tilt angle of the baffle 7, the larger the space it occupies. Therefore, those skilled in the art can determine the appropriate tilt angle of the baffle 7 according to the height dimension of the baffle 7, space requirements, etc.

[0083] In addition, in some embodiments, the baffle 7 is provided with ventilation holes.

[0084] In other words, this embodiment achieves the diversion of cold airflow by opening ventilation holes that penetrate the wall thickness of the baffle 7. While some of the cold air flows to the air guide surface of the air guide plate 1, another part of the cold air flows to the side of the air guide plate 1 away from the memory module 10. This solution is suitable for situations where electronic components (such as capacitors, supercapacitors, etc.) are set on the side of the air guide plate 1 away from the memory module 10, so as to use the cold airflow flowing through the ventilation holes to dissipate heat from the electronic components (such as capacitors, supercapacitors, etc.).

[0085] It should be noted that this embodiment does not limit the specific shape and size of the ventilation holes, as long as they can achieve the required cold air distribution. For example, the ventilation holes can be rectangular or circular. The number of ventilation holes can be one or multiple.

[0086] In addition, such as Figure 10 As shown, in order to facilitate heat dissipation for the server's processor, in some embodiments, the air duct also includes two opposing first side plates 81 and a top plate 82 connected between the two first side plates 81. The top plate 82 and the two first side plates 81 form a U-shaped ventilation channel 8, which is used to house the server's processor.

[0087] In other words, the air guide shroud in this embodiment also includes a ventilation duct 8. When the air guide shroud is applied to a server, the processor is located inside the ventilation duct 8, and the two first side plates 81 and the top plate 82 surround the outside of the processor to guide the airflow passing through the processor. It can be understood that the opening end of the U-shaped ventilation duct 8 faces the motherboard on which the processor is located. After the cool airflow enters the ventilation duct 8 from the air inlet end, it flows along the ventilation duct 8 to dissipate heat from the processor located inside the ventilation duct 8.

[0088] Furthermore, such as Figure 10 As shown, in some embodiments, the air guide plate 1 is connected to the end of the first side plate 81 away from the top plate 82; the end of the air guide plate 1 away from the first side plate 81 is connected to the second side plate 9, and the baffle 7 is connected to the first side plate 81 and the second side plate 9 respectively. The air guide plate 1 and the second side plate 9, the first side plate 81 and the baffle 7 connected thereto form an accommodating space.

[0089] It is understood that the air guide plate 1 is connected to the end of the first side plate 81 away from the top plate 82 and extends in a direction away from the ventilation duct 8. The second side plate 9 extends in a direction away from the air guide plate 1. The second side plate 9, the first side plate 81, and the baffle 7 are all located on the same side of the air guide plate 1. The second side plate 9 and the first side plate 81 are arranged opposite each other (for example, the second side plate 9 and the first side plate 81 can be arranged parallel to each other). The air guide plate 1, the second side plate 9, the first side plate 81, and the baffle 7 form an accommodating space for placing electronic components (such as capacitors or supercapacitors) to make full use of the space. This design, together with the baffle 7, has ventilation holes, which can be used to dissipate heat from the cold airflow passing through the ventilation holes to the electronic components in the accommodating space. At this time, the second side plate 9 and the first side plate 81 have an air guiding function.

[0090] In addition, such as Figure 10 As shown, in some embodiments, air guide plates 1 are provided on both sides of the ventilation duct 8, that is, the two air guide plates 1 are respectively connected to the ends of the two first side plates 81 away from the top plate 82, and the air guide plates 1 extend in the direction away from the ventilation duct 8. The air guide plate 1 located on one side of the ventilation duct 8 is connected to the second side plate 9 and the baffle 7. The air guide plate 1 and the second side plate 9, the first side plate 81 and the baffle 7 connected thereto form an accommodating space. The air guide plate 1 located on the other side of the ventilation duct 8 is connected to the baffle 7, and the air guide plate 1 and the baffle 7 are respectively provided with a first detachable connection structure 11 or a second detachable connection structure 12.

[0091] Furthermore, such as Figure 10 As shown, in some embodiments, a ventilation duct 8 and the air guide plates 1 on both sides form an air guide hood. The air guide plate 1 on one side of the ventilation duct 8 and its connected baffle 7 are provided with a first detachable connection structure 11 or a second detachable connection structure 12. The air guide plate 1 on the other side of the ventilation duct 8 and its connected second side plate 9, first side plate 81 and baffle 7 form an accommodating space. There can be one, two or other numbers of such air guide hood structures. For example, Figure 14 As shown, there are two such air guide covers. One of the air guide plates 1 on one side of the ventilation duct 8 of each of the two air guide covers is provided with a first detachable connection structure 11, and the other is provided with a second detachable connection structure 12. The two air guide covers are symmetrically arranged and spliced ​​together by the first detachable connection structure 11 and the second detachable connection structure 12 to form an air guide cover with two ventilation ducts 8 and four air guide plates 1.

[0092] In addition, such as Figure 14 As shown, in order to facilitate the connection between the air guide shroud and the server chassis, in some embodiments, the air guide plate 1 is provided with a mounting part 14, which is used to connect with the server chassis.

[0093] In other words, during installation, simply place the air guide cover inside the server chassis and connect the mounting part 14 to the server chassis.

[0094] It should be noted that this embodiment does not limit the specific structure of the mounting part 14. For example, the mounting part 14 can be a second protrusion protruding from the side of the air guide plate 1. The server chassis side wall can be provided with a limiting groove so that the air guide cover and the server chassis can be limited by the cooperation of the second protrusion and the limiting groove, thereby realizing the positioning and installation of the air guide cover on the server chassis. The second protrusion can be set in the limiting groove of the chassis side wall, and the guide cover is pressed together by the connection between the chassis top cover and the chassis base. Alternatively, the second protrusion can be inserted into the limiting groove, and the limiting groove limits the second protrusion vertically and horizontally, while the chassis side wall limits the guide cover horizontally, thus realizing the connection between the air guide cover and the server chassis. This installation structure is simple and can achieve tool-free installation.

[0095] In addition, in some embodiments, the air guide cover includes two air guide cover bodies as described above, and the second protrusion is provided at one end of the two air guide cover bodies that are far apart. For example, the second protrusion is provided on the second side plate 9 of the two air guide cover bodies respectively.

[0096] In addition, this embodiment does not limit the shape and number of the second protrusion. For example, each of the two air guide covers is provided with two second protrusions.

[0097] Of course, in other embodiments, the air guide can also be connected to the server chassis via a snap-fit ​​structure, such as by using a snap-fit ​​and slot-locking mechanism to connect the air guide to the server chassis.

[0098] Furthermore, such as Figure 1 As shown, in some embodiments, the end of the baffle 7 away from the air guide plate 1 is flush with the top plate 82, and the wing plate 13 extends out in a direction away from the ventilation duct 8 and the air guide plate 1.

[0099] In other words, the wing plate 13 is flush with the top of the top plate 82 and the baffle 7 and extends in the direction of the air inlet to form an edge structure, making it easier for the cold airflow to enter the ventilation duct 8 and the bottom of the air guide plate 1 to prevent airflow loss.

[0100] It should be noted that the width of the wing plate 13 is not limited in this embodiment. As long as the wing plate 13 extends beyond the air inlet of the ventilation duct 8 and the air guide plate 1, it can guide more cold air flow to the bottom of the ventilation duct 8 and the air guide plate 1.

[0101] Additionally, it should be noted that the above embodiments do not limit the specific material and forming method of the air guide cover. For example, the air guide cover can be made of plastic injection molding, as long as it can fit the internal space of the server chassis.

[0102] In addition to the aforementioned air guide cover, this embodiment of the invention also provides a server including the air guide cover disclosed in the above embodiments. For the structure of other parts of the server, please refer to the relevant technology, which will not be repeated here.

[0103] In other words, the key point of this embodiment is that the server includes the air guide shroud disclosed in any of the above embodiments, and at least has the beneficial effects of the air guide shroud, which will not be repeated here.

[0104] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0105] The foregoing has provided a detailed description of the air guide cover and server provided in this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely 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 various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this application.
