PROPELLER FAN AND AIR CONDITIONER HAVING THE SAME

摘要

A propeller fan includes: a hub which forms an oval shape when seen in an axial direction; multiple wings which extend from the hub; and reinforcing ribs which extend from the hub and are densely formed in the leading edges of the multiple wings. The propeller fan with such configuration can have competent blowing efficiency and rigidity while reducing the weight and the material costs.
