Abstract
A fan impeller structure includes a hub having a top and a sidewall; and a plurality of blades being circumferentially spaced on the sidewall. Each of the blades has a barrier zone formed at a tip portion of the blade; the barrier zone is used to prevent or block fluid at a lower side of the blade to turn over to an upper side of the blade owing to a difference in the pressure distributed over the upper and the lower side of the blade. Therefore, when a fan using the fan impeller structure is operating, the fan is able to maintain constant air flow and static efficiency to largely reduce vortices formed at the tip portions of the blades (also referred to as wingtip vortices) and accordingly, to reduce the occurrence of aerodynamic noise.
