    Abstract: An impeller is applied to a centrifugal fan and includes fan blades and a hub. Each fan blade includes a first portion and a second portion. The first portion is located relatively close to the hub and the first portion is coupled to the second portion. The first portion has a windward side and a leeward side, and the windward side is parallel to the leeward side. The second portion is located relatively far away from the hub. The second portion has a windward side and a leeward side, and the windward side and the leeward side are two curved surfaces with different specific curvatures.

    Abstract: A side-blown fan is formed by a case and a blade member. The case includes a side-outlet, an axial inlet and a protrusion. The protrusion extends from an edge of the axial inlet toward the center of the axial inlet. The blade member is embedded in the inside of the case. In the radial direction, a high air pressure region exists between the blade member and the case. The protrusion covers the high air pressure region and a part of the blade member.
