Compared with the traditional cooling fan, the centrifugal fan can output larger air quantity under the condition of smaller space occupation, and the cooling effect is improved. But the processing precision of the fan blade of the centrifugal fan is higher than that of a common fan, and the noise generated when the impeller has dust accumulation or runs at a high speed is also larger.
Meanwhile, for the heating element of the computer, the rapid guiding of the fluid and the rapid separation of the hot fluid are also the key of the product design.
