Abstract
The invention discloses a centrifugal fan with multiple groups of fan blades. The centrifugal fan consists of a motor, a fan assembly, a connector and a metal frame, wherein the fan assembly consists of an enclosure, a fan blade shaft, axial-flow type fan blades, centrifugal impellers, a bracket and a bearing. A motor shaft of the motor is integrally connected to the fan blade shaft of the fan assembly; and the motor and the fan assembly are supported and fixed through the metal frame. The enclosure is circular, and a section view of the enclosure is T-shaped. The fan blade shaft is mounted in the enclosure; and the multiple groups of fan blades on the fan blade shaft consist of 1-17 groups of axial-flow type fan blades and one group of centrifugal impellers. When the fan blade shaft rotates, air between two blades quickly moves towards the outer edge of the fan blade shaft due to centrifugal action, so that energy is transmitted, air pressure is quickly superposed to form high pressure, and speed of air force is increased. When air is re-introduced into the next group of fan blades by an air flue, the air is accelerated again; and the energy is transmitted through the multiple groups of fan blades, and air pressure is quickly superposed, so that high pressure or high suction force is formed.
