Abstract
A packaged fan having a hub, a rotor, fan blades extending outward from said rotor, an electric motor electrically coupled to said rotor, a fan casing surrounding an outside perimeter of said fan blades, and a plurality of support vanes extending from said hub to outside said fan casing and configured to attach to a support structure, the support vanes having planar portion traversing an air flow path, the planar portion having a major plane that is parallel to said air flow path.
Claims20
A packaged fan, comprising:
- a rotor with fan blades extending outward from the rotor;
- an electric motor coupled to the rotor;
- and
- a fan casing surrounding an outside perimeter of the fan blades,
- wherein a plurality of support vanes extend from the electric motor and through the fan casing to a position outside the fan casing, each support vane of the plurality of support vanes being configured to attach to a support structure and to transmit mechanical loads directly to the support structure.
