    • An improved generator fan serves to draw air into the generator through an inlet in the generator housing, pass the air through the rotor and stator, and direct the air out openings in the generator housing. The fan of the present invention includes a disc and at least one multi-directional blade extending from the disc. The multi-direction blade includes a leading segment extending from the disc between a first radius measured from the axis of rotation and a second radius, the leading segment including a leading edge extending from the disc at an angle of about ninety degrees from the disc, the leading segment extending from the disc with an increasing angle along the length of the leading segment; and a trailing segment extending from the disc between the second radius and a third radius measured from the axis of rotation, the third radius being greater than the second radius and the trailing segment extending from the disc with an angle having a rate of change different than the leading segment.
    • 改进的发电机风扇用于通过发电机壳体中的入口将空气吸入发电机,使空气通过转子和定子,并将空气引导到发电机壳体中的开口。 本发明的风扇包括盘和从盘延伸的至少一个多方向叶片。 所述多向叶片包括从所述盘在从所述旋转轴线测量的第一半径和第二半径之间从所述盘延伸的引导段,所述引导段包括从所述盘以大约九十度的角度从所述盘延伸的前缘, 所述引导段沿着所述引导段的长度从所述盘以增加的角度延伸; 以及从所述盘在所述第二半径和从所述旋转轴线测量的第三半径之间从所述盘延伸的后段,所述第三半径大于所述第二半径,并且所述后段从所述盘以从所述盘延伸的角度以不同于 领先部分。
