More Information
Summary:A fan structure includes an upper frame defining a receiving space and at least one recess communicable with the receiving space; a stationary blade frame connected to a lower side of the upper frame, and internally forming a flared air passage having a stator seat provided therein; and an annular impeller externally provided with at least one inclined section corresponding to the recess. The annular impeller is mounted on the stator seat and located in the receiving space of the upper frame, and includes a hub, a plurality of blades, and an annular member. An impeller air passage is defined between the hub and the annular member and is communicable with the flared air passage to together form an inner airflow path. An outer side passage leading to the inclined section is defined between the annular member and the at least one recess to form an outer airflow path.
