    • A system for cooling a heat-producing component in a computer system includes a conduit or plenum and a fan assembly. The fan assembly may be supported by the conduit. An air stream directing and acoustic shielding member is disposed in the conduit to prevent or reduce transmission of acoustic noise during operation of the fan assembly to a region outside the computer console. The shield member may be made of an open-cell foam or other sound deadening or reflecting material. A secondary conduit is provided for recirculating a portion of the internal air within the computer chassis. The internal air stream may be joined and mixed with the air stream from outside the chassis to provide both fresh air and recirculation cooling.
    • 用于冷却计算机系统中的发热部件的系统包括导管或增压室和风扇组件。 风扇组件可以由导管支撑。 气流引导和声屏蔽构件设置在导管中以防止或减少风扇组件操作期间声学噪声的传播到计算机控制台外部的区域。 屏蔽构件可以由开孔泡沫或其它消声或反射材料制成。 设置有用于使计算机机箱内部空气的一部分再循环的次级导管。 内部空气流可以与底盘外部的空气流接合并混合,以提供新鲜空气和再循环冷却。
