Traditional heat dissipation methods, such as axial-flow fans, have met basic heat dissipation needs to a certain extent, but have limitations in terms of efficient heat dissipation, quiet performance and durability. Centrifugal fan radiators came into being. They use the principle of centrifugal force to generate strong airflow through rotating blades to efficiently discharge the heat inside the device. Compared with axial-flow fans, centrifugal fan radiators are more complex in structure, but the heat dissipation efficiency is significantly improved, and the noise control is more outstanding.
