Abstract: The described embodiments relate generally to improving performance characteristics of a low profile fan. More specifically configurations having sloped fan blade edges are disclosed. By applying a gradual slope to each of the fan blades, performance of the fan can be increased without risking contact or rubbing between the fan blades and a fan housing. In some embodiments, the sloped fan blades can be configured to prevent contact when bearings of the fan include a certain amount of tilt play.

Abstract translation: 所描述的实施例一般涉及改进低调风扇的性能特性。 更具体地，公开了具有倾斜风扇叶片边缘的构造。 通过对每个风扇叶片施加逐渐的斜率，可以增加风扇的性能，而不会在风扇叶片和风扇壳体之间接触或摩擦的风险。 在一些实施例中，倾斜的风扇叶片可被构造成防止风扇的轴承包含一定量的倾斜运动时的接触。
