| description | A passive fan blade for a cooling package for use in an agricultural combine comprises a generally rectangular member having an axis, a central mounting area and two opposed legs, each leg having a middle region, a leading region and a trailing region, the leading and trailing regions being angled toward the downstream direction of intended air flow. The trailing regions increase in width in proportion to distance from the axis, while the leading regions decrease in width in proportion to distance from the axis, whereby the member is impelled to rotate in the direction of the leading edges when air flows past the member. In an assembly, the passive fan blade is mounted via a bearing assembly and mounting hardware onto a hub connected to a bracket. In a cooling package, the passive fan blade assembly is mounted on a frame in close proximity to a face of a radiator or a charge air cooler to provide turbulence thereby minimizing accumulation of chaff, dust and debris in order to maintain cooling efficiency. |
