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.
