Abstract: A centrifugal fan is provided. The centrifugal fan comprises a housing and an impeller. The housing includes an upper cover and a lower cover. The impeller is configured in the housing. The impeller includes a hub, a plurality of blades and an air guiding structure. The hub is pivoted on the lower cover and rotates around a rotation axis. The rotation axis extends in the axial direction. The blades are connected to a peripheral surface of the hub and configured between the upper cover and the lower cover. The air guiding structure is connected to the blades. An angle between the air guiding structure and the rotation axis increases along with a distance in the direction away from the hub.

Abstract: An impeller which is applied to a fan includes a hub, a plurality of first centrifugal blade and a plurality of second centrifugal blades. The hub is disposed in an accommodating space of the fan. The first centrifugal blades and the second centrifugal blades are connected to the hub. The first centrifugal blades have first ends away from the hub. The second centrifugal blades have second ends away from the hub. A distance between the second end and a center of the hub is larger than that between the first end and the hub center, and the first centrifugal blades and the second centrifugal blades are arranged periodically. Thus, an airflow noise in a constant frequency generated by the impeller can be avoided, and noises in inconstant frequency would not accumulate or generate annoying noise peak.
Abstract translation: 应用于风扇的叶轮包括轮毂，多个第一离心叶片和多个第二离心叶片。 轮毂设置在风扇的容纳空间中。 第一离心叶片和第二离心叶片连接到轮毂。 第一离心叶片具有远离轮毂的第一端。 第二离心叶片具有远离轮毂的第二端。 毂的第二端和中心之间的距离大于第一端和轮毂中心之间的距离，并且周期性地布置第一离心叶片和第二离心叶片。 因此，可以避免由叶轮产生的恒定频率的气流噪声，并且不变频率的噪声不会累积或产生烦人的噪声峰值。

Abstract: The disclosure provides a centrifugal fan, including an enclosure, a spacer, and a fan blade rotor. The enclosure includes a top panel, a bottom panel, and a side wall connected between the bottom panel and the top panel. The top panel, the bottom panel, and the side wall together form a first air exhaust vent and a second air exhaust vent. The spacer is disposed in the enclosure, is connected between the bottom panel and the top panel, and spaces a first space in communication with the first air exhaust vent and a second space in communication with the second air exhaust vent in the enclosure. The spacer includes a first opening. The first opening is in communication with the first space and the second space. The fan blade rotor is rotatably disposed in the second space.
