First claim

Opening claim text (preview).

What is claimed is: 1 . A fan structure comprising: a base; a fan inlet funnel coupled to the base, the fan inlet funnel having an inner surface for conducting air flow into a fan inlet and an outer surface; and a plurality of external ribs coupled to the outer surface of the fan inlet funnel. 2 . The fan structure of claim 1 wherein the base comprises a disc. 3 . The fan structure of claim wherein the base comprises a plurality of bolt holes. 4 . The fan structure of claim 1 wherein the fan inlet funnel comprises a curved portion. 5 . The fan structure of claim 1 wherein the fan inlet funnel comprises a straight portion. 6 . The fan structure of claim 1 wherein the fan inlet funnel comprises a curved portion and a straight portion. 7 . The fan structure of claim 1 wherein the fan inlet funnel comprises a first curved portion, a straight portion having a first end coupled to the first curved portion and a second curved portion coupled to a second end of the straight portion. 8 . The fan structure of claim 1 wherein the plurality of external ribs are disposed around a periphery of the fan inlet funnel. 9 . The fan structure of claim 1 wherein the plurality of external ribs are disposed around a periphery of the fan inlet funnel and are each separated from adjacent external ribs by approximately a same distance. 10 . The fan structure of claim 1 wherein the plurality of external ribs are coupled to the fan inlet funnel by one or more tabs. 11 . The fan structure of claim 1 wherein the plurality of external ribs extend from the base onto the fan inlet funnel. 12 . The fan structure of claim 1 wherein the plurality of external ribs follow a curvature of the fan inlet funnel. 13 . The fan structure of claim 1 wherein the plurality of external ribs curve radially around the fan inlet funnel in a clockwise or counter-clockwise direction. 14 . The fan structure of claim 1 wherein the plurality of external ribs extend for less than an entire length of the fan inlet funnel. 15 . The fan structure of claim 1 wherein the base, the fan inlet funnel and the plurality of external ribs are formed from a single material. 16 . The fan structure of claim 1 wherein the base, the fan inlet funnel and the plurality of external ribs are formed from a single material by a molding process. 17 . The fan structure of claim 1 wherein the base, the fan inlet funnel and the plurality of external ribs are formed from two or more different materials. 18 . The fan structure of claim 1 wherein the base has an inner diameter and an outer diameter, and the fan inlet funnel has a lower diameter, a minimum inner diameter and an upper outlet diameter. 19 . The fan structure of claim 1 wherein the base has an inner diameter D 4 and an outer diameter D 1 , and the fan inlet funnel has a lower diameter D 4 , a minimum inner diameter D 2 and an upper outlet diameter D 3 . 20 . The fan structure of claim 1 wherein the base has an inner diameter D 4 and an outer diameter D 1 , and the fan inlet funnel has a lower diameter D 4 , a minimum inner diameter D 2 and an upper outlet diameter D 3 , and where D 1 >D 4 >D 3 >D 2 .
