See full text

An impeller for a viscous flow fan includes a hub having a longitudinal axis, and a plurality of ring-shaped wave blades disposed about and coupled to a perimeter of the hub, the wave blades disposed in a parallel and spaced apart from one another along the longitudinal axis by a blade gap. Each wave blade includes a center coincident with the longitudinal axis, an inner perimeter, an outer perimeter, and a wave-like cross-section about the perimeter of the hub in a direction perpendicular to the longitudinal axis, wherein at least a portion of the inner perimeter of at least one of the wave blades is spaced from the perimeter of the hub to form an air intake gap.
