摘要:An improved axial-flow fan structure is disclosed and claimed, which includes a hub and a plurality of blades. The hub has a top surface and a side surface around which the plurality of blades is mounted. A lateral air intake region is formed above the top surface of the hub and surrounded by edge portions of all of the blades. A lateral air intake surface around the lateral air intake region is constituted by the edge portions of all of the blades. A part of each of the edge portions is fastened to the side surface of the hub.
