Abstract
The utility model relates to a low-noise axial flow fan, which comprises a motor and a blade that is driven by the motor. The utility model is characterized in that the low-noise axial flow fan also comprises a sound absorption rubber layer is fixed on the blade. The utility model has the advantages that the low-noise axial flow fan has better noise reduction function; the noise pollution of the fan to the surrounding environment can be eliminated without affecting the pneumatic performance of the fan; the fan has simple structure, reduces the weight of the blade and improves the efficiency; and the fan makes up the defect of the flat blade type in the aspect of air power.
Description
Technical field
The utility model relates to the heat dissipation ventilation axial-flow blower, particularly a kind of low noise axial fan.
Background technique
The noise of the more common in the market on-stream generation of blower fan usually becomes influences workers ' health and interference environment quietly brings disaster upon the source, has had a strong impact on people's proper functioning and rest, so that become public hazards.When the rotating speed of blower fan, pressure, when air quantity is big more, the noise that is sent is big more.The technology that is used in axial-flow blower noise reduction aspect at present mainly contains: strengthen the aerodynamic force load of leaf grating, reduce peripheral velocity; Increase wind wheel and air conducting tube gap; Reduce wind speed round, reduce blade quantity, strengthen blade area; Impeller is gone into out, a mouthful place adds the turbulent flow makeup and puts; Advance to establish zigzag structure on the trailing edge at movable vane; With the outside or inlets and putlets of ventilation in air conducting tube sound-absorbing material is set.Which kind of mode all more or less influences the aeroperformance of wind wheel.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of simple in structure, aeroperformance that does not influence blower fan, a kind of low noise axial-flow blower of excellent noise reduction effect are provided.
In order to achieve the above object, the technical solution of the utility model is achieved in that it is a kind of low noise axial fan, comprises that motor reaches the blade by driven by motor; It is characterized in that: also comprise the sound absorbent rubber layer that is fixed on the blade.
Described sound absorbent rubber layer has the sound absorption hole, and described sound absorption hole is radial and gathers.
Described sound absorbent rubber layer and blade body by paste fixing or quadric injection mould fix or rivet be bumped into fixing.
The utility model advantage compared with prior art is: have decrease of noise functions preferably, eliminated the noise pollution of blower fan to surrounding environment, and do not influence the aeroperformance of blower fan; Simple in structure, alleviate leaf weight, improved fan efficiency; Remedied the defective of dull and stereotyped blade profile aspect aerodynamic force.
Description of drawings
Fig. 1 is a stereogram of the present utility model;
Fig. 2 is the enlarged view of local B among Fig. 1.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
As shown in Figure 1, 2, it is a kind of low noise axial fan, comprises the blade 1 that motor 2 reaches by driven by motor; Characteristics of the present utility model are: also comprise the sound absorbent rubber layer 3 that is fixed on the blade 1.Because the sound absorbent rubber layer is fixed on the blade, so it does not influence the aeroperformance of blower fan, excellent noise reduction effect.
In the present embodiment, sound absorbent rubber layer 3 has sound absorption hole 31, and the sound absorption hole is radial gathers, so better absorption of noise.Sound absorbent rubber layer 3 and blade 1 body by paste fixing or quadric injection mould fix or rivet be bumped into fixing.
Claims (3)
1. a low noise axial fan comprises that motor reaches the blade by driven by motor; It is characterized in that: also comprise the sound absorbent rubber layer (3) that is fixed on the blade (1).
2. according to claim 1 described low noise axial fan, it is characterized in that: described sound absorbent rubber layer (3) has sound absorption hole (31), and described sound absorption hole is radial and gathers.
3. according to claim 1 described low noise axial fan, it is characterized in that: described sound absorbent rubber layer (3) and blade body by paste fixing or quadric injection mould fix or rivet be bumped into fixing.
