[0002] Graphics card, also known as GPU, is an important component of computer hardware. It is responsible for converting computer-generated image data into a format that the monitor can understand and present it on the monitor. The main functions of graphics cards include image rendering, video playback, video games, 3D modeling, scientific computing and many other fields.

[0003] At present, the fan of the graphics card is prone to accumulate dust during long-term operation, resulting in reduced heat dissipation efficiency and shortened fan life. However, the process of cleaning the fan is quite cumbersome, requiring the removal of the graphics card's back plate, PCB and radiator, which not only increases the workload and risk, but also may damage the graphics card. In addition, the existing graphics card cover is usually fixed on the radiator, with a fixed shape and color, which cannot meet the personalized needs of users and lacks the space and fun of later DIY modification.

That is to say, in this embodiment, since the length of the heat dissipation module 2 is greater than that of the PCB1, the protruding portion thereof is used to form the installation space 31, and the lower expansion unit 4 is installed in the installation space 31.

[0026] On the basis of the above embodiment, the lower expansion unit 4 in this embodiment includes two fixing seats 41 fixed on the heat dissipation module 2, and the two fixing seats 41 are arranged horizontally. Specifically, in this embodiment, bolts can be used to fasten the fixing seats 41, and a plurality of first docking columns 42 are arranged at intervals on the fixing seats 41;

[0027] A cover plate 43 is covered on the fixing seat 41, and a first docking hole 44 adapted to the first docking column 42 is opened on the side of the cover plate 43. That is, in this embodiment, a detachable cover plate 43 is adopted to shield the installation space 31 to avoid subsequent disassembly of the cover plate 43, thereby improving the convenience of cleaning the back end of the heat dissipation module 2.
