C-3212 SHROUD ARRANGEMENT FOR ENGINE COOLING FAN Abstract of the Disclosure: A bladed fan has an inlet shroud formed with a bell-mouthed inlet section which extends to an annular skirt portion affixed to the tips of the blades of the fan. The fan and the shroud are immersed within a: shroud fixed to an engine cooling radiator. This fixed shroud has an ejector section that extends to or beyond the rotating shroud and fan blading. The bell-mouthed inlet section has sufficient arc to prevent separation so that the fan operates at high efficiency and discharges air outwardly therefrom including the blockade of the clearance between the two shrouds to thereby effectively reduce air recirculation.
