    • A high efficiency and low noise inclined type fan assembly using a Taguchi design experiment method is provided to implement the high efficiency and low noise operation with minimal experiments. A high efficiency and low noise inclined type fan assembly using a Taguchi design experiment method includes a rear rotary plate(4), a front rotary plate(5), and a blade(7). The rear rotary plate is engaged with a rotary shaft of a motor by a key. The rear rotary plate has a diameter smaller than that of the front rotary plate. The front rotary plate has a ring shape having a diameter larger than that of the rear rotary plate. The blade is fixed to the rear rotary plate at its bent end by a detachable fixture(9). The other bent end is fixed to the front rotary plate by a detachable fixture to form an S-shaped cross section. The size of the duct, the number of blades, the angle of the blades, and the rotational radius of the blades are selected through the Taguchi design experiment method.
    • 提供了使用田口设计实验方法的高效率低噪声倾斜式风扇组件,通过最少的实验实现高效率和低噪声运行。 使用田口设计实验方法的高效率和低噪音倾斜式风扇组件包括后转盘(4),前旋转板(5)和叶片(7)。 后旋转板通过键与马达的旋转轴接合。 后转盘的直径小于前转盘的直径。 前转盘具有直径大于后转盘的直径的环形。 刀片通过可拆卸的夹具(9)在弯曲的端部固定到后转盘。 另一个弯曲的端部通过可拆卸的固定件固定到前旋转板以形成S形横截面。 通过田口设计实验方法选择管道的尺寸,叶片的数量,叶片的角度和叶片的旋转半径。
