Abstract

本申请提供了一种风扇及移动终端，该风扇包括壳体，以及设置在壳体内且可相对壳体转动的离心叶轮，离心叶轮包括多个叶片，多个叶片中的至少一个叶片上设置有多个沿叶片径向方向排列的沟槽，且沟槽相对叶片径向切线的法向方向成一定角度的倾斜设置。在使用时，气流相对于叶片的运动由沿叶片切向的速度和相对于离心叶轮半径的速度合成，即最终的相对速度并不平行于叶片的法向(与叶片的径向方向切线垂直的方向)，因此，为了让空气能以更顺畅的方式流过沟槽，本申请实施例设置的沟槽相对径向方向倾斜，从而使得沟槽的长度方向与相对速度的方向尽可能相同，从而提高了空气在沟槽上的通过性。进而提高通过效果，并且降低风扇造成的噪声。
