Abstract
A centrifugal fan assembly having an axis of rotation includes an inlet ring, a back plate, and a plurality of blades coupled between the inlet ring and the back plate. At least one blade of the plurality of blades includes a radially inner edge, a radially outer edge, and at least one flow channel extending obliquely therebetween. The at least one flow channel includes an inlet defined on the radially inner edge and an outlet defined on the radially outer edge, wherein the inlet and the outlet are positioned at different axial locations along a length of the blade.
Claims20
A centrifugal fan assembly including an axis of rotation, said assembly comprising:
- an inlet ring;
- a back plate;
- and
- a plurality of blades coupled between said inlet ring and said back plate, wherein at least one blade of said plurality of blades includes a radially inner edge, a radially outer edge, and at least one flow channel extending obliquely therebetween, wherein said flow channel includes an inlet defined on said radially inner edge and an outlet defined on said radially outer edge, said inlet and said outlet positioned at different axial locations along a length of said each blade.
A fan blade for use with a centrifugal fan assembly having an axis of rotation, said blade comprising:
- a radially inner edge;
- a radially outer edge;
- at least one flow channel extending obliquely between said radially inner edge and said radially outer edge, wherein said flow channel includes an inlet defined on said radially inner edge and an outlet defined on said radially outer edge, said inlet and said outlet positioned at different axial locations along a length of said each blade.
A method of forming a centrifugal fan assembly having an axis of rotation, said method comprising:
- forming an inlet ring;
- forming a back plate;
- forming a plurality of blades, wherein at least one blade of the plurality of blades includes a radially inner edge, a radially outer edge, and at least one flow channel extending obliquely therebetween, wherein the flow channel includes an inlet defined on the radially inner edge and an outlet defined on the radially outer edge, the inlet and the outlet positioned at different axial locations along a length of the each blade;
- and
- coupling the plurality of blades between the inlet ring and the back plate.
