Abstract
The invention discloses a low-noise axial flow fan, which comprises a main cylinder, an impeller component and a motor, wherein the impeller component is arranged in the main cylinder, the motor is arranged in the main cylinder and is fixed in the main cylinder through a support, the impeller component sleeves an output shaft of the motor, an inner corrosion-resistance layer is arranged on the inner surface of the main cylinder, an inner sound absorbing layer is arranged on the inner surface of the inner corrosion-resistance layer, an outer corrosion-resistance layer is arranged on the outer surface of the main cylinder, and an outer sound absorbing layer is arranged on the outer surface of the outer corrosion-resistance layer. According to the low-noise axial flow fan, the structure is simple and reasonable; the low-noise axial flow fan is suitable for places in which a large amount of fans are used; the noise is low, and the noise pollution can be reduced.
Description
Technical field
The present invention relates to axial-flow blower technical field, particularly relate to a kind of low noise axial fan.
Background technique
Axial-flow blower, purposes widely, is exactly air-flow equidirectional with the axle of fan blade, and as electric fan, air-conditioning outer machine fan is exactly that axial flow mode runs blower fan.Why being called " axial flow ", is because gas is parallel to fan shaft flowing.Axial fan is used in the occasion that traffic requirement is higher and pressure requirements is lower usually.Existing noise of axial flow fan is comparatively large, also needs to improve.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of low noise axial fan, simple and reasonable, and be applicable to the place that some blower fan use amounts are large, noise is little, can reduce noise pollution.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: provide a kind of low noise axial fan, comprise: main cylinder, be arranged on the wheel member of described main cylinder inside and be arranged on the motor of described main cylinder inside, described motor is fixed on main cylinder inside by support, described wheel member is sleeved on the output shaft of described motor, the internal surface of described main cylinder has interior anti-corrosion layer, the internal surface of described interior anti-corrosion layer has interior sound-absorption layer, the outer surface of described main cylinder has outer anti-corrosion layer, the outer surface of described outer anti-corrosion layer has outer sound-absorption layer.
In a preferred embodiment of the present invention, described interior sound-absorption layer and outer sound-absorption layer all adopt mineral wool acoustic board.
In a preferred embodiment of the present invention, described mineral wool acoustic board is bonded on the inside and outside wall of main cylinder respectively.
In a preferred embodiment of the present invention, described interior anti-corrosion layer and outer anti-corrosion layer are zinc coat.
The invention has the beneficial effects as follows: low noise axial fan of the present invention, simple and reasonable, be applicable to the place that some blower fan use amounts are large, noise is little, can reduce noise pollution.
