Description

Technical Field

[0001] This utility model relates to the field of computer equipment technology, specifically to a graphics card ventilation device. Background Technology

[0002] A graphics card, also known as a graphics processor card or video card, is a hardware device in a computer used for graphics processing and image output. Its main function is to convert the data processed by the CPU into image signals and display them on the monitor.

[0003] Chinese patent CN222088040U discloses "a graphics card exhaust device". By adding a flow-guiding component, it effectively guides the airflow generated by the fan module, ensuring that the airflow can pass smoothly through the heat sink, significantly improving the heat dissipation performance of the heat dissipation module, thereby reducing the operating temperature of the graphics card and improving the overall stability of the system. This solves the problems of rebound wind and wind noise caused by unilateral airflow in traditional heat dissipation systems. Secondly, the second fin design is composed of multiple arc-shaped fins, which not only increases the heat dissipation area, but also further improves the heat exchange efficiency.

[0004] However, in practical applications, graphics cards are usually installed inside the computer case, and their cooling fans have a fixed direction. When DIY users assemble their computers according to their usage scenarios and cooling needs, if they need to adjust the airflow direction of the graphics card to achieve a better cooling path or avoid airflow interference with other hardware, the installation direction of the graphics card cannot be flexibly changed due to the limitations of the motherboard slot structure. Users can only use additional devices such as graphics card extension cables to move the graphics card to other positions to change the airflow direction. This method not only increases the installation complexity, but also affects signal stability and the overall structural compactness, thus causing inconvenience to the installation and use of the graphics card.

[0005] In view of this, we propose a graphics card ventilation device. Utility Model Content
