Technical Notes: Study of radiator cooling fan for Motorcycles

摘要

The conventional fan for motorcycles seems to be used in the radial flow region at the operating point. This design method, which applied the concept of the Diagonal flow design, achieved a delay of the stalling And improved the static pressure efficiency at the Operating point in the high pressure region. In the case where the shroud ring was fixed to the Blade tips and rotated with the fan, the noise level is Minimal.
