ABSTRACT:
A serial fan includes a frame, a plurality of rotor vanes, at least one motor for driving the rotor vanes and a support connected to the frame through a plurality of connecting parts for receiving the at least one motor. The plurality of rotor vanes are arranged in series in the frame along an axial direction and the plurality of connecting parts are disposed therebetween to minimize space occupied by the serial fan in the axial direction, and effectively increase the blast pressure.
