    • A dual-intake fan which is a so-called sirocco fan used for venting air is disclosed. The fan has a structure in which a portion of an exhaust outlet is formed to be inclined while the centers of a scroll housing and an impeller are disposed to be eccentric so that noise can be reduced while air flow can be effectively guided by the scroll housing to the maximum extent and the air flow rate can be increased. The fan includes an impeller on which a plurality of blades are installed for rotating so as to create air flow, and a scroll housing formed so that the air drawn in through an air inlet by the impeller can be guided along a gradually expanding passage of the scroll housing, and the lower portion of an exhaust outlet is composed of at least one incline formed to be inclined upward toward any one side. In addition, the rotation center of the impeller and the center of the air inlet are disposed to be eccentric.
    • 公开了一种双进气风扇,它是用于排放空气的所谓的西洛克风扇。 风扇具有这样的结构,其中排气出口的一部分形成为倾斜,同时涡旋壳体和叶轮的中心被设置为偏心的,使得可以减少噪音,同时可以通过涡旋壳体有效地引导空气流动 在最大程度上可以增加空气流量。 风扇包括叶轮,多个叶片安装在该叶轮上以便旋转以产生空气流;以及涡旋壳体,其形成为使得通过叶轮通过空气入口吸入的空气能够沿着叶片的逐渐扩大的通道被引导 涡旋壳体,并且排气出口的下部由至少一个形成为朝向任何一侧向上倾斜的倾斜角构成。 此外,叶轮的旋转中心和空气入口的中心被设置为偏心的。
