An impeller with hybrid blades can be used in any blowers, which are applied in many fields such as cooling computers and HVAC. The impeller increases air flow as well as pressure. Each hybrid blade extends from the impeller hub with the shape of an axial fan blade and smoothly transforms at a proper radius of the impeller to the shape of a centrifugal blower blade. In addition, a dual-tunnel blower with multiple outlets is also presented.
