Description
Technical Field
[0001] This utility model relates to the field of server technology, and in particular to an installation structure for a server dual-width GPU. Background Technology
[0002] In the field of high-performance computing, GPUs play a crucial role in performing large-scale parallel computing tasks, such as deep learning, artificial intelligence, and scientific computing. To meet the demands of increasingly demanding computing tasks, more powerful dual-width GPUs are required. Typically, the number of dual-width GPUs is increased as much as possible within a server chassis of the same specifications to improve computing density and performance, thereby enhancing the server's computing power.
[0003] When installing dual-wide GPUs in server chassis, the common practice is to rely on the PCIe slot and the GPU's gold fingers for connection, using the included mounting brackets to secure the GPU to the chassis. However, these mounting brackets, due to their width, limit space utilization when installing GPUs horizontally. For example, a 2U server can only accommodate three dual-wide GPUs horizontally, thus reducing the server's computing performance. Furthermore, existing devices for installing dual-wide GPUs are structurally complex, causing inconvenience for users during installation, removal, and subsequent maintenance. Utility Model Content
[0004] The purpose of this invention is to provide an installation structure for dual-width GPUs in servers, which makes the installation of dual-width GPUs more compact and increases the installation density of dual-width GPUs in chassis of the same specifications.
[0005] To achieve the above objectives, the solution of this utility model is as follows: an installation structure for a server dual-width GPU, including a first bracket and a second bracket fixedly installed on a server chassis. The first bracket has two first fixing parts with a height difference. The second bracket has two second fixing parts with heights matching the first fixing parts. An adapter board is fixedly connected between the first fixing parts and the second fixing parts. The two adapter boards are respectively provided with plug-in parts. The two plug-in parts are arranged opposite each other and staggered vertically, allowing two dual-width GPUs to be plugged in and installed in opposite directions.
[0006] In a preferred embodiment, the two adapter boards are a first Riser card and a second Riser card. The height of the insertion part of the first Riser card is less than the height of the insertion part of the second Riser card. The insertion part of the first Riser card is for the dual-width GPU to be inserted and installed with its front side facing upwards, and the insertion part of the second Riser card is for the dual-width GPU to be inserted and installed with its back side facing upwards.
[0007] In a preferred embodiment, the first bracket extends obliquely to form two first fixing members with a height difference, and the two first fixing members are bent relative to each other in the horizontal direction to form two first fixing parts.
[0008] In a preferred embodiment, the first fastener has a plurality of first mounting holes for fasteners to pass through and fix the first bracket to the server chassis.
[0009] In a preferred embodiment, the first fixing part has a plurality of first through holes for fasteners to pass through and for two adapter plates to be mounted opposite each other and parallel to the first fixing part.
[0010] In a preferred embodiment, the second bracket has several second mounting holes at both ends for fasteners to pass through and fix the second bracket to the server chassis.
[0011] In a preferred embodiment, one side of the second bracket is longitudinally bent to form two second fixing members. The two second fixing members form second fixing parts at positions that match the two first fixing parts. The second fixing parts are provided with second through holes for fasteners to pass through and for the two adapter plates to be installed opposite each other and parallel on the second fixing parts.
[0012] In a preferred embodiment, the second fastener has a fixing hole for the fastener to pass through and fix the dual-width GPU onto the second fastener.
[0013] In a preferred embodiment, one of the two second fasteners is U-shaped, with a fixing hole located above the U-shaped fastener for mounting the dual-width GPU with its reverse side facing upwards.
[0014] In a preferred embodiment, the other of the two second fasteners is L-shaped, with a fixing hole located below the L-shaped second fastener for mounting the dual-width GPU with its front facing upwards.
[0015] The beneficial effects of this utility model after adopting the above solution are as follows: This utility model forms two first fixing parts with a height difference on the first bracket, and cooperates with the second fixing part on the second bracket. After the two plug-in plates are installed between the first fixing parts and the second fixing parts, the plug-in parts on the two plug-in plates are arranged in a staggered manner. Through the installation method of one positive and one negative, the structure of the two dual-width GPUs after installation is more compact. The first bracket and the second bracket have simple structures, which are convenient for users to install and remove. This effectively improves the installation density of dual-width GPUs in the same specification chassis, thereby improving the performance of a single server. Attached Figure Description

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0027] This embodiment provides an installation structure for a server with dual-width GPUs, such as... Figures 1 to 7 As shown, it includes a first bracket 1 and a second bracket 2 fixedly mounted on a server chassis. The first bracket 1 has two first fixing parts 11 with a height difference. The second bracket 2 has two second fixing parts 21 with heights matching the first fixing parts 11. The first fixing parts 11 and the second fixing parts 21 are fixedly connected to an adapter plate 3. The two adapter plates 3 are respectively provided with plug-in parts 30. The two plug-in parts 30 are arranged opposite each other and staggered vertically, allowing two double-width GPUs 4 to be plugged in one in the right direction and the other in the wrong direction.
[0028] In this embodiment, two first fixing parts 11 with a height difference are formed on the first bracket 1, and two second fixing parts 21 with the height matching the first fixing parts 11 are formed on the second bracket 2. After the adapter plate 3 is fixedly installed on the first fixing parts 11 and the second fixing parts 21, the plug-in parts 30 of the two adapter plates 3 can be staggered vertically, and the projections of the two plug-in parts 30 in the vertical direction coincide, which effectively utilizes the vertical space. Thus, the two dual-width GPUs 4 can be plugged in and installed in a positive and negative manner, avoiding the space waste caused by the traditional side-by-side installation method. The two dual-width GPUs 4 after installation are more compact, and more dual-width GPUs 4 can be accommodated in the same size server chassis, thereby improving the performance of a single server.
[0029] In this embodiment, the two first fixing parts 11 of the first bracket 1 and the two second fixing parts 21 of the second bracket 2 are all integrated into one design, which is simple in structure and makes it more convenient for users to install or remove the dual-width GPU4, and is also conducive to later maintenance.
[0030] like Figure 1 and Figure 2 As shown, the two adapter boards 3 are a first Riser card 31 and a second Riser card 32. The height of the insertion part 30 of the first Riser card 31 is less than the height of the insertion part 30 of the second Riser card 32. The insertion part 30 of the first Riser card 31 is for the dual-width GPU to be inserted and installed with the front 6 facing upwards, and the insertion part 30 of the second Riser card 32 is for the dual-width GPU to be inserted and installed with the back 7 facing upwards.
[0031] In this embodiment, the two ends of the first Riser card 31 and the two ends of the second Riser card 32 are respectively fixed to the first fixing part 11 and the second fixing part 21. The two plug-in parts 30 form a height difference, which is used for mounting the GPU on the front and back, improving the vertical space utilization inside the chassis. In this embodiment, the plug-in part 30 is a PCIe slot for the gold fingers of the dual-width GPU 4 to be inserted and mated.
[0032] like Figure 3 and Figure 4 As shown, the first bracket 1 extends obliquely to form two first fixing members 10 with a height difference, and the two first fixing members 10 are bent relative to each other in the horizontal direction to form two first fixing parts 11.
[0033] In this embodiment, the included angle between the first fixing part 11 and the first fixing member 10 is 90 degrees, so that the two adapter plates 3 are parallel to each other after being installed on the first fixing part 11, which helps to improve space utilization. The two first fixing members 10 and the first bracket 1 are integrally molded, making the adapter plate 3 more stable after installation. The structure is simple, which simplifies the installation and removal process of the first bracket 1 and is also beneficial for users' later maintenance.
[0034] like Figure 3 and Figure 4 As shown, the first fastener 10 has a plurality of first mounting holes 100 for fasteners to pass through and fix the first bracket 1 on the server chassis.
[0035] In this embodiment, fasteners can easily pass through the first mounting hole 100 and, together with the opening on the chassis, fix the first bracket 1, thereby simplifying the loading and unloading process.
[0036] like Figure 4 As shown, the first fixing part 11 has a plurality of first through holes 110 for fasteners to pass through and for two adapter plates 3 to be mounted opposite each other and parallel on the first fixing part 11.
[0037] In this embodiment, fasteners pass through the first through hole 110 and cooperate with the opening on the adapter plate 3, thereby firmly installing the adapter plate 3 onto the first fixing part 11, forming a stable connection structure and facilitating the user's installation and removal of the adapter plate 3. In this embodiment, each first fixing part 11 has two first through holes 110. In other embodiments, the user can adjust the number of first through holes 110 according to the actual situation.
[0038] like Figure 6 As shown, the second bracket 2 has several second mounting holes 22 at both ends for fasteners to pass through and fix the second bracket 2 on the server chassis.
[0039] In this embodiment, the second bracket 2 is elongated, which helps to improve the stability of the second bracket 2 after installation. Second mounting holes 22 are provided at both ends of the bracket. Fasteners can easily fix the second bracket 2 onto the server chassis through the second mounting holes 22. The structure is simple, easy to install and remove, and the number of second mounting holes 22 can be adjusted by the user.
[0040] like Figure 5 and Figure 6 As shown, one side of the second bracket 2 is longitudinally bent to form two second fixing members 20. The two second fixing members 20 respectively form second fixing parts 21 at positions that match the two first fixing parts 11. The second fixing parts 21 are provided with second through holes 210 for fasteners to pass through and for the two adapter plates 3 to be installed opposite each other and parallel on the second fixing parts 21.
[0041] In this embodiment, the second bracket 2 is longitudinally bent to form the second fixing member 20, with a bending angle of 90 degrees. The height of the second fixing part 21 matches the height of the first fixing part 11. The design of the second through hole 210 on the second fixing part 21 allows the fastener to securely install the adapter plate 3 onto the second bracket 2. The structure is simple and easy to install and remove. The position and size of the second fixing part 21 can be adjusted according to actual needs to accommodate different models of adapter plates 3 and hardware components.
[0042] like Figure 5 and Figure 6 As shown, the second fastener 20 has a fixing hole 200 for the fastener to pass through and fix the dual-width GPU4 onto the second fastener 20.
[0043] In this embodiment, after the dual-width GPU4 is plugged into the plug-in portion 30 of the adapter board 3, it can be further locked and fixed by fasteners in conjunction with the fixing holes 200 on the second fixing member 20, ensuring the stability of the server during use. Of course, the number of fixing holes 200 can be adjusted according to the actual situation.
[0044] like Figure 5 As shown, one of the two second fixing members 20 is in the shape of a U-shape, and a fixing hole 200 is opened above the U-shaped fixing member for mounting the dual-width GPU with the reverse side 7 facing upward.
[0045] When the dual-width GPU 7 is installed with its reverse side 7 facing upwards, the opening for the mounting hole 200 is located above the second fastener 20. Therefore, one of the two second fasteners 20 is U-shaped, with the mounting hole 200 located above it, allowing for locking and securing by passing a fastener through the mounting hole 200 of the second fastener 20 and engaging with the opening of the dual-width GPU 4. In this embodiment, one of the second fasteners 20 adopts a U-shaped design, such as... Figure 7 As shown, while ensuring installation strength, it can reduce the obstruction of the dual-width GPU4 air intake, improve airflow inside the chassis, and thus enhance the heat dissipation effect.
[0046] like Figure 5 As shown, the other second fixing member 20 of the two second fixing members 20 is L-shaped, and the fixing hole 200 is opened below the L-shaped second fixing member 20 for mounting the dual-width GPU with the front 6 facing upward.
[0047] When the dual-width GPU 4 is mounted with its front side facing upwards, the opening for the mounting hole 200 is located below the second fixing member 20. Therefore, the other second fixing member 20 is L-shaped, with the mounting hole 200 located below it. This allows for locking and fixing by passing a fastener through the mounting hole 200 of the second fixing member 20 and engaging with the opening of the dual-width GPU 4. In this embodiment, the other second fixing member 20 adopts an L-shaped design, such as... Figure 7 As shown, while ensuring installation strength, it reduces obstruction of the dual-width GPU4 air intakes, improving airflow within the chassis and thus enhancing heat dissipation. Furthermore, the L-shaped design also helps reduce the amount of materials used in production, lowering production costs and simplifying manufacturing.
[0048] In this embodiment, the fastener can be a bolt and nut or other locking device for fixing, but is not limited to this, which facilitates locking and unlocking and makes loading and unloading convenient.
[0049] like Figure 8 As shown, taking the 2U chassis 5 as an example, the usage process in this embodiment is as follows:
[0050] The user uses fasteners to fix the first bracket 1 onto the 2U chassis 5 through the first mounting hole 100 of the first bracket 1 and the opening of the 2U chassis 5. The user also uses fasteners to fix the second bracket 2 onto the 2U chassis 5 through the second mounting holes 22 at both ends of the second bracket 2 and the opening of the 2U chassis 5.
[0051] The first bracket 1 extends obliquely to form two first fixing members 10 with a height difference. The two first fixing members 10 are bent relative to each other in the horizontal direction to form two first fixing parts 11. The two first fixing parts 11 are provided with first through holes 110. The two adapter plates 3 are installed on the first fixing parts 11 in a relatively parallel manner through the first through holes 110 using fasteners.
[0052] The second bracket 2 is longitudinally bent on one side to form two second fixing members 20. The two fixing members are provided with two second fixing parts 21 that match the height of the first fixing part 11. The second fixing parts 21 are provided with second through holes 210. The two adapter plates 3 are installed on the second fixing parts 21 in a relatively parallel manner through the second through holes 210 using fasteners.
[0053] The two ends of the two adapter plates 3 are respectively fixed between the first fixing part 11 and the second fixing part 21. The plug-in parts 30 on the two adapter plates 3 are arranged in an alternating manner, and the projections of the two plug-in parts 30 in the vertical direction coincide.
[0054] Then, the two dual-width GPUs 4 are inserted and installed on the connector 30 of the adapter board 3 in a reverse orientation, thus forming a set of dual-width GPUs 4 horizontally. At this time, the width occupied by the two dual-width GPUs 4 is exactly half the width of the 2U chassis 5. The other set of dual-width GPUs 4 can be installed in the same way as described above.
[0055] The directional terms used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.
[0056] The above description is only a preferred embodiment of this utility model and is not a limitation on the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
