Abstract

The invention discloses an ultra-thin centrifugal ventilator, which comprises an ultra-thin volute, an air inlet and an air outlet, wherein the air inlet is formed in the side face of the ultra-thin volute; the air outlet is formed in the end face of the ultra-thin volute; one side, which is the same as the air inlet, of the ultra-thin volute is provided with a fan mounting bracket; an impeller is arranged in the ultra-thin volute; a structure of a single shaft extension outer rotor three-phase asynchronous motor comprises an outer rotor and an inner stator; the inner stator is coaxially arranged in the outer rotor; an induction coil is wound on the inner stator; a rear end cover and the inner stator are of an integral structure; a motor shaft is coaxially arranged in the inner stator through front bearings and the rear bearings; an elastic wave washer covers the motor shaft between the front bearings and the rear bearings; one end of the motor shaft is coaxially embedded in the outer rotor; one end, which is coaxially embedded into the outer rotor, of the motor shaft and the outer rotor is arranged on the fan mounting bracket; an end cover is arranged on the ultra-thin volute; the outer rotor and the impeller are connected through a flange.

Description

technical field [0001] The invention relates to a fan, in particular to an ultra-thin centrifugal fan. Background technique [0002] At present, centrifugal fans are widely used in air-conditioning and other fields. Most of the existing centrifugal fans use double-shaft outer-rotor motors or single-shaft inner-rotor motors. A centrifugal fan with a double-shaft extension outer rotor motor has a large installation space and high manufacturing cost; a centrifugal fan with a single shaft extension inner rotor motor has a lot of noise and unstable operation; how to design a method that can avoid both methods at the same time Centrifugal fans with shortcomings have become a trend for further research. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an ultra-thin centrifugal fan which can save installation space. [0004] In order to solve the above technical problems, the technical solution adopted by the present in...
