Abstract
A serial fan includes a frame, a plurality of rotor vanes, a support connected to the frame through a plurality of connecting parts. 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.
Claims19
A serial fan comprising:
- a frame;
- a first rotor vane having a first hub and at least one first blade connected to the first hub;
- a second rotor vane having a second hub and at least one second blade connected to the second hub;
- at least one motor within the first hub or the second hub for driving the first rotor vane and the second rotor vane;
- and
- a support connected to the frame through a plurality of air-guiding blades capable of increasing the blast pressure of air flow through the serial fan,
- wherein the first rotor vane, the second rotor vane and the plurality of air-guiding blades are arranged in series in the frame along an axial direction, and the plurality of air-guiding blades are disposed therebetween and adjacent to the first rotor vane and the second rotor vane to minimize space occupied by the serial fan in the axial direction and increase the blast pressure of air flow through the serial fan.
