Description

Display card and display card system

The present disclosure relates to a display card and a display card system, and more specifically, the present disclosure relates to a display card and a display card system capable of maintaining heat dissipation efficiency.

At present, the heat dissipation design of display cards of computers in the industry can be roughly divided into axial flow fan heat dissipation design and turbo fan heat dissipation design. The airflow direction of the axial flow fan is perpendicular to the fan body. After the airflow blows over the cooling fins, the airflow will hit the graphics card body, resulting in a large airflow resistance and reducing the heat dissipation efficiency. The turbo fan has poor heat dissipation efficiency due to the long distance from the cooling fins to the air outlet at the end and the large flow resistance.

From the above, it can be known that the heat dissipation layouts commonly used in the industry at present are all due to the large impedance of the air flow field, resulting in poor heat dissipation effects. Therefore, there is a need for a display card and a display card system that solve the poor aerodynamic and heat dissipation efficiency caused by excessive flow resistance.

In order to solve the above known problems, the present disclosure provides a display card, including a display card body, a fin assembly, and a fan.

The air inlet of the fan is perpendicular to a main shaft, and the air outlet of the fan is perpendicular to the extending direction. The fan drives the airflow to flow through the second fin along the extending direction from the air outlet of the fan.

In an embodiment of the present disclosure, the second fin extends away from the top surface of the display card body along a main axis away from the top surface of the display card body. The second fins are arranged along an arrangement direction. When viewed along the extension direction, there is a space between each second fin. The fan drives an airflow from an air outlet of the fan to flow through the space between the second fins along the extending direction. The distances between the second fins are different.
