ABSTRACT:
A fan includes a frame, a motor base, an impeller, an airflow guiding component, and at least one outwardly expanded part. The motor base is disposed in the frame, and the impeller is disposed on the motor base. The outwardly expanded part, connected with the frame, is disposed at an airflow inlet or an airflow outlet, for increasing areas of intake airflow or discharge airflow. One end of the airflow guiding component is connected with the motor base, and the other end is connected with an inner surface of the frame, instead of being connected with the outwardly expanded part, to prevent the fan from forming blocks on the frame during molding process.
