Beschreibung
Zusammenfassung:	The invention provides a fan impeller comprising a fan hub, an outer annular frame surrounding the fan hub, and a plurality of mutually independent metal blades; each metal blade comprises a root portion and an end portion, wherein at least partial the root portion is buried in the fan hub, and at least partial the end portion is embedded in the outer annular frame; the metal blades, plastic fan hub, and the plastic outer annular frame can be combined in a cladding moulding manner, thus increasing the blade number, and increasing drivable air quantity. 本发明提供种风扇叶轮，其包含扇毂、环绕扇毂的外环框及相互独立的复数金属叶片。各金属叶片的二端分别为根部以及末端，根部的至少部分嵌埋于扇毂，末端的至少部分嵌埋于外环框。凭借包覆设出成型的方式结合金属叶片、塑胶扇毂及塑胶外环框而能够增加可设置的叶片数量以增加可驱动的风量。
