Abstract:
To make manifest the above noted desire, a revelation of the present invention is brought forth. A fan assembly (7) is provided including a hub (10) with a plurality of projecting fan blades (12). A recirculating flow element (18) is provided which is generally forward adjacent an outer diameter of the fan blades (12). A plurality of guide vanes (22) are positioned within the recirculating flow element (18). The guide vanes (22) have an inlet angle (24) that is nearly tangential with an outer diameter surface (15) of the recirculating flow element (18). The guide vanes (22) have an outlet angle (26) which is nearly radial along an inner diameter surface (17) of the recirculating flow element (18).
