Abstract
An airflow-doubling vane structure includes an axle, an inner vane unit, and an outer vane unit. The inner vane unit includes a plurality of vanes provided around a center defined by the axle and can be rotated along with the axle. The vanes of the inner vane unit are centrifugal vanes. The outer vane unit includes a plurality of vanes provided around the center defined by the axle and around the inner vane unit and can be rotated along with the axle. The vanes of the outer vane unit are axial-flow vanes and extend a certain radial distance from the vanes of the inner vane unit.
Claims6
An airflow-doubling vane structure, comprising:
- an axle configured to be provided on and rotated by a rotating power source;
- an inner vane unit comprising a plurality of vanes connected to, and provided around a center defined by, the axle, the inner vane unit being rotatable along with the axle, each said vane of the inner vane unit having a width in an axial direction, the vanes of the inner vane unit being centrifugal vanes, the inner vane unit further comprising a disc-shaped base portion coupled to the axle, and the vanes of the inner vane unit being provided on an outer periphery of the base portion such that an airflow is able to be drawn into the inner vane unit and then move outward in a radiating manner in radial directions of the inner vane unit;
- and
- an outer vane unit comprising a plurality of vanes provided around the center defined by the axle and around the inner vane unit, the vanes of the outer vane unit extending in radial directions of the inner vane unit for a radial distance ranging from one to ten times the width of each said vane of the inner vane unit, and the vanes of the outer vane unit being axial-flow vanes in order to propel the airflow forward, and a hollow portion is formed on each of the vanes of the outer vane unit.
