Abstract:
A fan impeller structure and a cooling fan thereof. The fan impeller structure consisting of a hub and a flow guide body. The hub has an extension section extending from outer circumference of the hub. The extension section has a first face and a second face. An axial center of the flow guide body is defined with an axial line. A fitting section outward extends from the axial line. A spoiler section is connected to the fitting section in a direction away from the axial line. The spoiler section is formed with multiple axial perforations that communicate with multiple radial perforations. The flow guide body is disposed on the first or second face of the extension section of the hub. The flow guide body is employed to replace the blades of conventional cooling fan. The perforations of the flow guide body can forcedly guide air in a narrow space.

Claim (Index 1):
A fan impeller structure consisting of a hub and a flow guide body, the hub having an extension section extending from outer circumference of the hub, the extension section having a first face and a second face, an axial center of the flow guide body being defined with an axial line, a fitting section outward extending from the axial line, a spoiler section being connected to the fitting section in a direction away from the axial line, the spoiler section being formed with multiple axial perforations that communicate with multiple radial perforations such that an airflow is guided through said perforations and propelled by said spoiler, the flow guide body being disposed on the first face or the second face of the extension section of the hub, and the flow guide body is selected from a group consisting of a foamed porous structure, a spongey, porous wooden material and a foamed metal.
