Golf Fan Story
Golf Ball
A golf ball performs within specified velocity, distance, and symmetry limits. A ball moving through air experiences two major aerodynamic forces, lift and drag. Dimpled balls fly farther than non-dimpled balls due to the combination of two effects, dimple and backspin.
Structure
First, the dimples on the surface of a golf ball cause the boundary layer on the upstream side of the ball to transition from laminar to turbulent. The turbulent boundary layer creates a narrower, low pressure and hence less pressure drag. The reduction in pressure drag causes the ball to travel farther.
The Golf Fan
Since 2003, Zaward has applied the patented design of dimple surface in the impellers of a Golf fan, hence the distinctive shape of Golf fan has long been Zaward’s trademark. The concept derives from the golfball’s dimple surface, which reduces air resistance and turbulence and lifeforce when rotating and results in extremely quiet operation whilst raising airflow volume. Each golf fan blades consist of numerous dimples facilitate lift force when rotating, meanwhile, reduce the noise level. Besides, the carefully crafted Golf fan frame offers enhanced air intake.
