Abstract: An impeller is provided, including a metal housing, a shaft, and a plastic member. The metal housing has a shaft mounting hole. The inner surface of the shaft mounting hole includes three or more contact points, and the contact points are closer to the shaft than other portions of the inner surface of the shaft mounting hole. The shaft passes through the shaft mounting hole and is affixed by the contact points. The metal housing divides the shaft into an upper section, a middle section, and a lower section. The plastic member passes through the shaft mounting hole and is in contact with the middle section.

Abstract: A centrifugal fan with dual outlets in the same direction includes a fan frame, an impeller, and a motor. The fan frame includes an upper cover, a base plate and a first air deflector. The base plate and the upper cover are connected to form an accommodating space and an air outlet plane. The first air deflector is arranged near the air outlet plane and divides the air outlet plane into a first air outlet and a second air outlet. The impeller is disposed in the accommodating space. The impeller and the side wall of the fan frame form a flow channel therebetween. The motor connects the impeller and drives it to rotate. The first air deflector extends inward the flow channel from the air outlet plane and the end of the first air deflector has a first guide portion, which is a slant surface.

Abstract translation: 具有相同方向的双出口的离心式风扇包括风扇框架，叶轮和电动机。 风扇框架包括上盖，底板和第一空气导流板。 基板和上盖连接以形成容纳空间和空气出口平面。 第一空气导流器布置在空气出口平面附近，并将空气出口平面分成第一空气出口和第二空气出口。 叶轮设置在容纳空间中。 风扇框架的叶轮和侧壁在其间形成流动通道。 电机连接叶轮并驱动它旋转。 第一空气导流器从空气出口平面向内延伸流动通道，并且第一空气导流器的端部具有作为倾斜表面的第一引导部分。
