Abstract: A diagonal fan is disclosed and includes a frame and an impeller. The frame includes an inlet, an outlet, an accommodation space and a guiding wall. The inlet and the outlet are communicated through the accommodation space. The guiding wall is extended along an axial direction to the accommodation space. The impeller is accommodated within the accommodation space and includes a conical section shell. When the impeller is rotated, an airflow flowing is generated. The outer diameter of the hub of the impeller is expended gradually in a direction from the inlet toward the outlet, so that the flowing direction of the airflow is expended gradually around the peripheral of the impeller. A gap having a spacing distance is substantially maintained to form a backflow channel. A backflow is transported through an intake section, a horizontal section and an exhaust section of the backflow channel, and converged with the airflow.

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.

Abstract: A fan includes a frame, an impeller, a driving assembly and a circuit board. The frame includes an inlet, an outlet, a first accommodation space, a base and a second accommodation space, wherein the inlet and the outlet are disposed at opposite sides of the frame, and the first accommodation space is separated from the second accommodation space. The impeller is disposed in the first accommodation space and on the base. The driving assembly is disposed between the base and the impeller. The circuit board is disposed in the second accommodation space. The base includes plural first through holes, and the impeller includes plural second through holes. During the fan is operating, a first airflow is formed to flow from the inlet to the outlet, and a second airflow is formed to flow through the driving assembly via the plural first through holes and the plural second through holes.
