Description
Technical field
The utility model belongs to axial fan technical field, relates to a kind of axial fan of super-silent natural wind.
Background technique
Axial fan is civilian or industrial common apparatus, can be used for blowing or pull out wind carrying out cooling, the quality of axial fan depends on the aspect such as liquid form, maintainability of its serviceability, radiating efficiency, air-out, though its form is many, but basic structure as shown in Figure 1, axial fan, the fan blade 2, the control gear that comprise the rotor 1 be arranged on fan body, are in transmission connection by the rotor 1 of motor; Its fan blade 2 is exactly the helical vane being distributed on rotor multiple curvecd surface type lengthy motion picture shapes of 1 one weeks, and the entirety revolution contoured surface of its fan blade 2 is in the form of annular discs, and the blowing air of its fan blade 2 is to the wind being the single form with the axis of fan shaft being parellel.
Adopt the axial fan of such technology certainly can use, but due to its fan blade 2 relatively long, during rotation, its fan blade 2 has relatively significantly axial runout unavoidably, and dynamic balancing is good not, noise is naturally also large; Because its blowing air is to being dull vertically in parellel, dry not naturally soft, durable not enough in structure, using effect is desirable not enough.
Model utility content
For overcoming the deficiencies in the prior art, the utility model provide a kind of structure more optimize durable, good dynamic balance is super-silent, the axial fan of soft, the using effect of blowing nature more preferably super-silent natural wind.
The utility model for the technological scheme reaching above-mentioned technical purpose and adopt is: a kind of axial fan of super-silent natural wind, the fan blade, the control gear that comprise the rotor be arranged on fan body, are in transmission connection by the rotor of motor; Fan blade is aluminium castings, and aluminium castings comprises inner ring blade, outer ring blade, interior ring, the outer ring that integrated aluminium casts shape; Interior ring and outer ring are coaxially connected by the inner ring blade between the inner ring surface of the outer ring surface with outer ring that are distributed on interior ring; Outer ring blade is distributed on the outer ring surface of outer ring; The rotor of motor and the inner ring surface of interior ring are fastenedly connected; The entirety revolution contoured surface of outer ring blade is ring plate-like; The entirety revolution contoured surface of inner ring blade is tapered tube shape.
The blowing air of described outer ring blade is to being be parellel with the axis of fan shaft; The blowing air of inner ring blade is to being acute angle with fan shaft and in outside divergent shape.
Described motor is external rotor electric machine.
Described motor is inner rotor motor.
The beneficial effects of the utility model are: because fan blade is aluminium castings, and aluminium castings comprises inner ring blade, outer ring blade, interior ring, the outer ring that integrated aluminium casts shape; Interior ring and outer ring are coaxially connected by the inner ring blade between the inner ring surface of the outer ring surface with outer ring that are distributed on interior ring; Outer ring blade is distributed on the outer ring surface of outer ring; The rotor of motor and the inner ring surface of interior ring are fastenedly connected; The entirety revolution contoured surface of outer ring blade is ring plate-like; The entirety revolution contoured surface of inner ring blade is tapered tube shape.
Because fan blade of the present utility model is that integrated aluminium casts shape, more durable; Be improved to by shorter inside and outside circle blade due to fan blade and by casting with inside and outside ring the composite structure be connected as a single entity, ensure that dynamic balancing is better, noise is less from structure; Because the entirety revolution contoured surface of outer ring blade is ring plate-like; The entirety revolution contoured surface of inner ring blade is tapered tube shape, therefore, two strands of wind that inside and outside circle blade blows out respectively produce turbulent flow after mutually impacting, and the wind of producing by boasting after mixing is softer natural and blowing covering space scope that is mixing wind is larger, radiating efficiency is higher, and using effect is better.

Embodiment
Embodiment of the present utility model, as shown in Figures 2 to 5, a kind of axial fan of super-silent natural wind, the fan blade 2, the control gear that comprise the rotor 1 be arranged on fan body, are in transmission connection by the rotor 1 of motor; Fan blade 2 is aluminium castings, and aluminium castings comprises inner ring blade 5, outer ring blade 6, interior ring 3, the outer ring 4 that integrated aluminium casts shape; Interior ring 3 and outer ring 4 are coaxially connected by the inner ring blade 5 between the inner ring surface of the outer ring surface with outer ring 4 that are distributed on interior ring 3; Outer ring blade 6 is distributed on the outer ring surface of outer ring 4; The rotor 1 of motor is fastenedly connected with the inner ring surface of interior ring 3; The entirety revolution contoured surface of outer ring blade 6 is ring plate-like; The entirety revolution contoured surface of inner ring blade 5 is tapered tube shape.
The blowing air of described outer ring blade 6 is to being be parellel with the axis of fan shaft; The blowing air of inner ring blade 5 is to being acute angle with fan shaft and in outside divergent shape.
Described motor is external rotor electric machine.
Described motor is inner rotor motor.
The utility model can be applicable to the fan of the equipment cooling such as fan, motor of lowering the temperature between civilian fan, industrial truck.During for civilian fan, because wind is softer natural and blowing covering space scope that is mixing wind is larger, noise is little, can be used as sleep fan.During fan for the cooling of the equipment cooling such as motor, due to the wind in parellel existing in mixing wind, having again is the wind of the outside divergent shape of shape, and the hot blast of equipment periphery can be diffused into larger space relatively faster and go, and radiating efficiency is higher.
