Abstract

An air inlet for axial-flow fan comprises a housing and an impeller. The housing has a pressure-boosting inlet section and an air channel. The impeller is located in the air channel, and has a hub and a plurality of blades. The blades are provided on an outer circumference of the hub, and each of the blades has an outer corner end formed on its upstream topmost point. Further, each axial position of the outer corner ends is disposed within the pressure-boosting inlet section. When the impeller is rotated, airflow can be initially propelled by the outer corner ends of the blades to carry out a pointed wind-shear state. Then, the airflow is driven by the blades and smoothly passed through the pressure-boosting inlet section so as to prevent from generating air-noise due to turbulence in the pressure-boosting inlet section.
