Abstract
The utility model discloses 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.By the way, the utility model is simple and reasonable, and be applicable to the place that some blower fan use amounts are large, noise is little, can reduce noise pollution.
Description
Technical field
The utility model relates to axial-flow blower technical field, particularly relates 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.
Model utility content
The technical problem that the utility model 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 utility model 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 the utility model preferred embodiment, described interior sound-absorption layer and outer sound-absorption layer all adopt mineral wool acoustic board.
In the utility model preferred embodiment, described mineral wool acoustic board is bonded on the inside and outside wall of main cylinder respectively.
In the utility model preferred embodiment, described interior anti-corrosion layer and outer anti-corrosion layer are zinc coat.
The beneficial effects of the utility model are: the utility model 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.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of the utility model low noise axial fan one preferred embodiment;
Fig. 2 is the cross-sectional view of described main cylinder.
In accompanying drawing, the mark of each parts is as follows: 1, main cylinder, and 2, wheel member, 3, motor, 4, interior anti-corrosion layer, 5, interior sound-absorption layer, 6, outer anti-corrosion layer, 7, outer sound-absorption layer.
Embodiment
Be clearly and completely described to the technological scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 and Fig. 2, the utility model is embodiment comprise:
A kind of low noise axial fan, comprise: main cylinder 1, be arranged on the wheel member 2 of described main cylinder 1 inside and be arranged on the motor 3 of described main cylinder 1 inside, it is inner that described motor 3 is fixed on main cylinder 1 by support, described wheel member 2 is sleeved on the output shaft of described motor 3, the internal surface of described main cylinder 1 has interior anti-corrosion layer 4, the internal surface of described interior anti-corrosion layer 4 has interior sound-absorption layer 5, the outer surface of described main cylinder 1 has outer anti-corrosion layer 6, the outer surface of described outer anti-corrosion layer 6 has outer sound-absorption layer 7, described interior sound-absorption layer 5 and outer sound-absorption layer 7 have good sound-absorbing effect, noise pollution can be reduced, described interior anti-corrosion layer 4 and outer anti-corrosion layer 6 improve the decay resistance of main cylinder 1.
Preferably, described interior sound-absorption layer 5 and outer sound-absorption layer 7 all adopt mineral wool acoustic board, and described mineral wool acoustic board is bonded on the inside and outside wall of main cylinder 1 respectively.
Preferably, described interior anti-corrosion layer 4 and outer anti-corrosion layer 6 are zinc coat.
The beneficial effects of the utility model are: the utility model 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.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
