Abstract
A fan wheel assembly includes at least three hub rings and a connecting member. Each outer circumference of the hub rings provides with extension fan blades. The connecting member serially connects the hub rings which are coaxially stacked in a longitudinal direction to constitute the fan wheel assembly. Each extension fan blade of one of the hub rings extends into two adjacent extension fan blades of the other two of the hub rings that each leading edge of one layer of the extension fan blades overlaps the other two layers of the extension fan blades along a longitudinal direction. Thereby, the overlapped extension fan blades can increase total blade-surface area of the fan wheel assembly.
