TECHNICAL FIELD

[0001] The utility model relates to a display card technical field especially relates to a piezoelectric fan heat dissipation display card. BACKGROUND

[0002] With the development of electronic technology, the performance of display card is increasing, and the higher heat is produced. Effective heat dissipation system becomes the key to guarantee the stable operation of display card. At present, the air cooling heat dissipation system is the mainstream way of display card heat dissipation, and the fan used mainly has two types of axial flow fan and centrifugal fan.

[0003] The axial flow fan forms a blind area in the center area of the fan due to its structural characteristics, which leads to insufficient air flow in the area, affecting the heat dissipation effect. In the high heat density equipment such as display card, the problem of central blind area is particularly prominent, which may cause the core temperature of display card to be too high, affecting the performance and service life.

[0004] And although the centrifugal fan can provide relatively uniform air flow, the flow field has a bias problem, which means that the air flow does not completely uniformly cover the entire heat dissipation surface, especially on the irregular surface of the display card, the air flow coverage effect of the centrifugal fan is poor, which also affects the heat dissipation efficiency.

[0005] In summary, the existing axial flow fan and centrifugal fan have obvious deficiencies in the air cooling heat dissipation of display card. Therefore, in order to improve the heat dissipation efficiency and stability of display card, we propose a piezoelectric fan heat dissipation display card. UTILITY MODEL CONTENT
