Cooling fan without returning flow
A cooling fan without returning flow comprises a motor stator, a frame and a motor rotor. The frame is joined to the stator with a support device at the inlet side thereof. The motor rotor is disposed at the stator. A fan blade set is disposed under the rotor and at the outlet side of the frame. An airflow area of the outlet can be increased to prevent the outlet side from producing a stagnation zone so as to increase cooling area and reduce noise.
