Problems solved by technology

[0004] However, since the heat generated by the current display card 2a is too large, it is necessary to increase the rotational speed of the centrifugal fan 4a to achieve the heat dissipation performance required by the display card 2a.
However, when the rotational speed of the centrifugal fan 4a increases, the noise generated by the centrifugal fan 4a will increase sharply, which will cause noise disturbance to the user.

Abstract

A radiator with superimposed fans comprises a centrifugal fan and an axial-flow fan, wherein, the axial-flow fan is arranged on one side of the centrifugal fan, so that airflow blown from the axial-flow fan can be blown to the centrifugal fan. Therefore, the centrifugal fan and the axial-flow fan can run at a lower rotational speed, and overall noise generated by the radiator can be reduced further.

Description

【Technical field】 [0001] The present invention mainly relates to a radiator, especially a radiator with stacked fans. 【Background technique】 [0002] Due to the rapid development of technologies such as 3D animation and video games, computer systems need more efficient graphics cards to process huge amounts of data, which also causes the graphics card to generate a huge amount of heat. In order to solve the heat dissipation problem of the display card, a heat dissipation module is usually installed on the display card. [0003] see figure 1 , is a perspective view of a known display device. The display device 1a includes a display card 2a and a heat dissipation module 3a. The heat dissipation module 3a is arranged on the display card 2a. A centrifugal fan 4a is arranged in the heat dissipation module 3a. The centrifugal fan 4a is used to rotate rapidly along a first The airflow direction D1 sucks in air, and then the air flows out from around the centrifugal fan 4a, and b...
