Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of graphics card backplates, specifically to an aluminum backplate structure. Background Technology
[0002] As an important component of the graphics card, the graphics card backplate has functions beyond just protecting the PCB board. It also supports the weight of the graphics card, enhances heat dissipation, and improves overall stability. Aluminum alloy is the most common material for graphics card backplates. It is lightweight, high-strength, and has good heat dissipation performance, which can effectively protect the graphics card PCB.
[0003] Existing backplates are generally fixed directly to the back of the graphics card with screws, and have a simple structure, mainly a single-board structure. When the graphics card PCB is in use, the temperature distribution in the heat-generating area is uneven, and it is prone to deformation under high temperature. The PCB is easily heated and may cause local deformation. The backplate serves to support and fix the PCB and prevent deformation. However, the strength of a single-board backplate is limited, and the graphics card fan needs to draw air from the backplate. Some backplates have ventilation holes, but if there are too many holes, it will affect the overall strength and reduce the effectiveness of the backplate in supporting the PCB. Utility Model Content
[0004] This invention provides an aluminum backplate structure with the advantages of high air intake heat dissipation efficiency and high strength, thereby solving the problem of low air intake heat dissipation efficiency of existing backplates.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum backplate structure, comprising an aluminum backplate body and a reinforcing plate, wherein:
[0006] The aluminum backplate body has multiple mounting holes on its surface, and a first mounting screw is movably connected in each mounting hole. A heat dissipation component is provided in the middle of the aluminum backplate body. The heat dissipation component is located near the middle of the aluminum backplate body and includes multiple equidistant heat dissipation fins with through gaps between them. The heat dissipation fins extend to the upper end of the aluminum backplate body.
[0007] In addition to the heat dissipation components, the aluminum back plate body has multiple circular heat dissipation holes near the center, and the area where the heat dissipation holes are located corresponds to the hollow part of the reinforcing plate.
[0008] The aluminum back panel body has multiple air inlet slots, all of which are through slots, and the air inlet slots are distributed in a ring around the outside of the aluminum back panel body. The hollow part of the reinforcing plate corresponds to the air inlet slots.
[0009] The reinforcing plate is detachably installed at the bottom of the aluminum back plate body. The reinforcing plate is hollow inside and has multiple first reinforcing ribs and second reinforcing ribs fixed inside.
[0010] The first reinforcing rib is constructed into a rectangular frame located in the hollow part of the reinforcing plate, and the second reinforcing rib is fixed at equal intervals between the rectangular frame composed of the first reinforcing rib and the reinforcing plate.
[0011] As a preferred technical solution of this utility model, the reinforcing plate is provided with a plurality of fixing holes corresponding to the mounting holes around its periphery. The fixing holes are movably connected to the first mounting screws. The reinforcing plate is detachably mounted on the bottom of the aluminum back plate body by means of the first mounting screws, so that the reinforcing plate is connected to the aluminum back plate body.
[0012] As another preferred technical solution of this utility model, the reinforcing plate is symmetrically installed with connecting base plates on its side end, and the aluminum back plate body is symmetrically installed with fixing base plates on its side end. The connecting base plates and fixing base plates correspond to each other and are each provided with corresponding holes. The connecting base plates and fixing base plates are connected by a second mounting screw, so that the reinforcing plate is connected to the aluminum back plate body.
[0013] Compared with the prior art, the present invention provides an aluminum backplate structure, which has the following advantages:
[0014] 1. This utility model improves the air intake efficiency of the back of the graphics card by using multiple air intake slots on the aluminum backplate body, thus improving the heat dissipation effect of the graphics card. Furthermore, the reinforcing plate that can be detachably installed at the bottom of the aluminum backplate body can strengthen the overall strength of the backplate, thereby improving the deformation support strength while improving the air intake efficiency. This not only improves the heat dissipation efficiency but also prevents the graphics card PCB from deforming.
[0015] 2.

A heat dissipation component 13 is provided in the middle of the aluminum backplate body 1, and multiple air inlet slots 11 are provided in the aluminum backplate body 1.
[0027] The reinforcing plate 2 is detachably installed at the bottom of the aluminum back plate body 1. The reinforcing plate 2 is hollow inside and has a plurality of first reinforcing ribs 22 and second reinforcing ribs 23 fixed therein.
[0028] Furthermore, the reinforcing plate 2 is provided with a plurality of fixing holes 21 corresponding to the mounting holes 15 around its periphery. The fixing holes 21 are movably connected to the first mounting screws 3, and the reinforcing plate 2 is detachably mounted on the bottom of the aluminum back plate body 1 by means of the first mounting screws 3.
[0029] Specifically, before installing the backplate, place the reinforcing plate 2 at the bottom of the aluminum backplate body 1, and then use the first mounting screw 3 to pass through the mounting hole 15 and the fixing hole 21, and then continue to tighten the first mounting screw 3 to fix the aluminum backplate body 1 and the reinforcing plate 2 to the back of the graphics card.
[0030] Furthermore, all of the aforementioned air inlet slots 11 are through slots, and the air inlet slots 11 are respectively distributed around the outside of the aluminum back plate body 1, and the hollow part of the reinforcing plate 2 corresponds to the air inlet slots 11.
[0031] Specifically, the multiple air inlets 11 can greatly improve the air intake efficiency from the outside, and can also help dissipate heat from the central part where the temperature is higher.
[0032] Furthermore, the heat dissipation component 13 is located near the middle of the aluminum back plate body 1, and includes multiple heat dissipation fins 131 arranged at equal intervals. There are through gaps between the heat dissipation fins 131. The heat dissipation fins 131 extend to the upper end of the aluminum back plate body 1. Multiple circular heat dissipation holes 12 are opened in the part of the aluminum back plate body 1 near the middle. The area where the heat dissipation holes 12 are located corresponds to the hollow part of the reinforcing plate 2.
[0033] Specifically, the above design allows for heat dissipation through the heat sink fins 131 and the heat dissipation holes 12, preventing excessive local temperatures on the graphics card PCB.
[0034] The first reinforcing rib 22 is constructed into a rectangular frame located in the hollow part of the reinforcing plate 2, and the second reinforcing rib 23 is fixed at equal intervals between the rectangular frame composed of the first reinforcing rib 22 and the reinforcing plate 2.
[0035] Specifically, the arrangement and structure of the first reinforcing rib 22 are to prevent components from protruding on the PCB board surface, while the arrangement of the second reinforcing rib 23 improves the overall strength of the reinforcing plate 2. Example 2
[0036] For the fixing method of the replacement reinforcing plate 2 in this embodiment, please refer to the attached document. Figure 5 , Figure 6 The reinforcing plate 2 is symmetrically equipped with a connecting seat plate 24 on one side, and the aluminum back plate body 1 is symmetrically equipped with a fixing seat plate 14 on one side. The connecting seat plate 24 and the fixing seat plate 14 correspond to each other and are each provided with corresponding holes. The connecting seat plate 24 and the fixing seat plate 14 are connected by a second mounting screw 4.
[0037] It should be noted that, see Appendix Figure 7 On the reinforcing plate 2, at the position corresponding to the first mounting screw 3, grooves are provided to avoid affecting the installation of the first mounting screw 3.
[0038] In this embodiment, before installing the backplate, the reinforcing plate 2 is placed at the bottom of the aluminum backplate body 1, so that the fixing plate 14 on the aluminum backplate body 1 is aligned with the connecting plate 24 on the reinforcing plate 2.

[0039] The working principle and usage process of this utility model are as follows: During the use of the graphics card, the fan on the graphics card starts to work to dissipate heat from the graphics card. External air enters from the air intake slot 11 at the bottom backplate of the graphics card. Since the aluminum backplate body 1 is fixed to the graphics card PCB board, it supports and fixes the graphics card PCB board. At the same time, the reinforcing plate 2 fixed to the back of the graphics card PCB board reinforces and supports the aluminum backplate body 1. During the operation of the graphics card, the part with a higher temperature in the middle of the graphics card PCB board is dissipated through the heat dissipation fins 131 and heat dissipation holes 12 to prevent the local temperature of the graphics card PCB board from becoming too high.
