Abstract: An impeller includes a hub and a plurality of blades. The blades are arranged around the hub, and each blade includes a leading edge, a blade tip, a root portion, a trailing edge, a windward side and a leeward side. The windward side including a first turning point and a second turning point, a first vertical height difference is formed from the blade tip to the first turning point, and a second vertical height difference is formed from the first turning point to the second turning point, and the first vertical height difference is greater than the second vertical height difference. The impeller apparently reduces the noise.

Abstract: A serial-type diagonal fan assembly having a first fan and at least one second fan is provided. The first fan has a first front fan frame and a first fan wheel. A first hub of the first fan wheel has a radial cross-sectional area increased from a top toward a bottom of the first hub. The second fan has a second front fan frame and a second fan wheel, the second hub of the second fan wheel has an axial cross-sectional area increased from a top to a bottom of the second hub. The first fan and the second fan are arranged in a series. A spoiler is arranged on a second air inlet of the second front fan frame, an outer edge of the spoiler is embedded in a positioning groove of the second front fan frame without protruding from the second front fan frame.

Abstract: An axial fan includes a fan frame, an impeller and a motor. The fan frame has a frame body, a base and plural connecting members. The base is disposed at the center of a side of the frame body. The connecting members connect the frame body to the base. The impeller is accommodated in the frame body and disposed on the base. The impeller has a rotating shaft, a hub and plural blades disposed around the hub. The motor is disposed on the base and connects with the rotating shaft to drive the impeller to rotate. When the impeller rotates forwardly, the airflow is induced to flow through the connecting members, blades, and one side of the frame body away from the base. When the impeller rotates reversely, the airflow is induced to flow through the side of the frame body, blades and connecting members.
