Description

Technical Field

[0001] This utility model relates to the field of GPU backplate design, and in particular to a GPU backplate sheet metal structure. Background Technology

[0002] A Graphics Processing Unit (GPU), also known as a display core, display chip, or video processor, is a coprocessor used for processing images and graphics calculations. It is widely used in personal computers, workstations, and some mobile devices (such as smartphones and tablets). As an important branch of hardware, GPUs are widely used in scientific computing, artificial intelligence, game development, and other fields.

[0003] As mainstream GPUs in the market have seen improvements in computing performance, their thermal design power has also increased. This has led to a greater variety of components on the back of the GPU chip motherboard, requiring more sophisticated backplate structures for protection. Traditionally, backplates are manufactured using die casting, with grooves and through-holes in the backplate to accommodate components with height restrictions. This die casting process is costly, and the difficulty in adjusting the backplate's mounting method to suit specific needs results in poor protection for the GPU chip motherboard and challenging installation. Utility Model Content

[0004] The purpose of this invention is to provide a GPU backplate sheet metal structure that allows for flexible adjustment of the fixing method of different areas of the backplate according to the requirements of the GPU chip motherboard, thereby reducing installation difficulty and improving the protection capability of the GPU chip motherboard.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sheet metal structure for a GPU backplate includes a support section, a bending section, a fixing through hole, and a base.

[0007] The support is fixedly installed on the side of the base facing the GPU chip motherboard.

[0008] The bending section is located at the edge of the base and is used to fix it to the GPU chip motherboard after bending.

[0009] The fixing through hole is located at the center of the base along its length, and is used to confirm the base position according to the GPU chip motherboard.

[0010] Furthermore, the mounting vias include GPU chip mounting plate vias and inductor vias.

[0011] The GPU chip mounting plate has square through holes with extension slots at the four corners, and is positioned at the center of the base corresponding to the GPU position on the GPU chip motherboard.

[0012] The inductor vias are multiple square holes arranged side by side, used to correspond to other heat-generating components on the GPU chip motherboard, and are located near the vias on the GPU chip mounting plate.

[0013] Furthermore, the GPU chip mounting plate has through holes for spacers at the four corners of the through holes.

[0014] Furthermore, the support portion includes riveted spacer posts and adhesive spacer posts.

[0015] The riveting spacers are located at both ends of the base along its length, corresponding to the riveting through holes on the GPU chip motherboard.

[0016] The adhesive spacer is even attached to the through hole of the spacer.

[0017] Furthermore, the bending portion is located at the edge of the base and is used for bending and fixing according to the specifications of the GPU chip motherboard.

[0018] Furthermore, the base is provided with a socket pin through hole at a position away from the through hole of the GPU chip fixing plate.

[0019] The socket pin through-hole is used to locate the power socket position on the GPU chip motherboard.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects:

[0021] This invention achieves compatibility with GPU chip motherboards of different specifications through a bending section on the motherboard. Furthermore, different fixing methods are used for the spacer mounting backplate to protect critical parts of the GPU chip motherboard, addressing the different areas requiring protection on different specifications of GPU chip motherboards. Specifically, press-fit spacers are used for usable areas of the GPU chip motherboard, while adhesive spacers are used for unusable areas, i.e., densely packed chip areas, to prevent damage to the GPU chip motherboard during installation and subsequent use. Because different fixing methods are used for different parts of the GPU chip motherboard, installation is simpler, and the protection and support capabilities for the GPU chip motherboard after installation are improved.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

They are only for the convenience of describing this utility model and 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 utility model.

[0027] Example:

[0028] like Figure 1 and Figure 2 As shown in the figure, this utility model embodiment proposes a GPU backplate sheet metal structure, including a support part 1, a bending part 2, a fixing through hole 3 and a base 4.

[0029] The support 1 is fixedly installed on the side of the base 4 facing the GPU chip motherboard.

[0030] The bending part 2 is located at the edge of the base 4 and is used to fix it to the GPU chip motherboard after bending.

[0031] The fixing through hole 3 is located at the center of the base 4 along its length, and is used to confirm the position of the base 4 according to the GPU chip motherboard.

[0032] In this embodiment, the backplate needs to be installed on the GPU chip motherboard. First, the bending part 2 is bent according to the specifications of the GPU chip motherboard so that the size of the base 4 part is adapted to the GPU chip motherboard. Then, the fixing through hole 3 on the base 4 is aligned with the chip position on the GPU chip motherboard. Finally, after confirming the position of the support part 1 according to the chip distribution on the GPU chip motherboard, the backplate is fixed to the GPU chip motherboard by the cooperation of the support part 1 and the bending part 2.

[0033] Furthermore, the fixing through hole 3 includes a GPU chip fixing plate through hole 5 and an inductor through hole 6.

[0034] The through-hole 5 of the GPU chip mounting plate is a square through-hole with extension grooves at the four corners, and is set at the center of the base 4 corresponding to the GPU position on the GPU chip motherboard.

[0035] The inductor through-hole 6 consists of multiple square holes arranged side by side, used to correspond to other heat-generating components on the GPU chip motherboard, and is located near the through-hole 5 on the GPU chip mounting plate.

[0036] Specifically, due to the different heat dissipation specifications of the chips on the GPU chip motherboard, different through holes are needed on the base 4 for different heat-generating areas. This allows for more precise positioning between the backplate and the GPU chip motherboard, and also facilitates heat dissipation for the GPU chip motherboard chips. The area with the highest heat generation uses a square design with extension slots at the four corners, providing ample space for heat dissipation and preventing damage to the GPU chip motherboard due to heat buildup.

[0037] Furthermore, the GPU chip mounting plate has through holes 7 for spacers at the four corners of the through hole 5.

[0038] Furthermore, the support portion 1 includes riveted spacer posts 8 and adhesive spacer posts 9.

[0039] The riveting spacer 8 is disposed at both ends of the base 4 along its length, corresponding to the riveting through holes disposed on the GPU chip motherboard.

[0040] The adhesive spacer 9 is even attached to the through hole 7 of the spacer.

[0041] Specifically, due to the dense circuitry in the chip-dense sections of the GPU motherboard, using the riveted spacer posts 8 during installation would easily damage the base 4 when mounting it onto the motherboard. This also increases the difficulty of mounting the base 4 onto the GPU motherboard. Because of the riveting requirement, different specifications of GPU motherboards require different backplates, significantly increasing production costs. Therefore, for areas with fewer chips on the GPU motherboard, the base 4 uses riveted spacer posts to provide stable support. For areas with more chips, the base 4 uses adhesive spacer posts 9 to provide support, reducing damage to critical components during installation. To facilitate confirmation of the adhesive spacer post 9's position, corresponding through holes 7 are provided on the base 4 for positioning the installation location before attaching the adhesive spacer post 9, ensuring a successful installation.

[0042] Furthermore, the bending portion 2 is disposed at the edge of the base 4 for bending and fixing according to the specifications of the GPU chip motherboard.

[0043] In another embodiment, since the specifications of the GPU chip motherboard have changed slightly, its length and width have changed compared to the previous GPU chip motherboard. Therefore, the size of the backplate can be adjusted by adjusting the bending part 2, thereby achieving adaptation to the new specification GPU chip motherboard. This improves the applicability of the backplate and reduces production costs.

[0044] Furthermore, the base 4 is provided with a socket pin through hole 10 at a position away from the through hole 5 of the GPU chip fixing plate.

[0045] The socket pin through-hole 10 is used to locate the power socket position on the GPU chip motherboard.

[0046] Specifically, the power socket on the GPU chip motherboard is usually located far from the GPU chip module, and the socket protrudes from the GPU chip motherboard. Therefore, it is necessary to set a socket pin through hole 10 on the base 4. This is to facilitate the subsequent installation and connection of the power supply, and also to confirm the installation direction of the base 4 through the socket pin through hole 10, thereby reducing the installation difficulty.

[0047] Compared with the prior art, the present invention has at least the following beneficial effects:

[0048] This invention achieves compatibility with GPU chip motherboards of different specifications through a bending section on the motherboard. Furthermore, different fixing methods are used for the spacer mounting backplate to protect critical parts of the GPU chip motherboard, addressing the different areas requiring protection on different specifications of GPU chip motherboards. Specifically, press-fit spacers are used for usable areas of the GPU chip motherboard, while adhesive spacers are used for unusable areas, i.e., densely packed chip areas, to prevent damage to the GPU chip motherboard during installation and subsequent use. Because different fixing methods are used for different parts of the GPU chip motherboard, installation is simpler, and the protection and support capabilities for the GPU chip motherboard after installation are improved.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
