Abstract
The invention discloses a kind of axial fan, comprise motor, impeller, the all identical blade of multiple shape, size is circumferentially evenly distributed with at impeller outer, the diameter of impeller is 98mm, the sweepforward angle of blade is increased in nonlinear Distribution to blade tip gradually by blade root, the sweepforward angle of blade root is 0 °, and the sweepforward angle of blade tip is 3.5 °; The chord length of described blade to be increased gradually to blade tip by blade root and linearly distributes, blade root chord length is 45.5mm, and blade tip chord length is 48.5mm, and the established angle of blade reduces in nonlinear Distribution by blade root to blade tip gradually, blade root established angle is 30 °, and blade tip established angle is 28.5 °.The present invention that have employed technique scheme, by having carried out rational design to blade shape, quantity, windup-degree etc., makes its fan in the past of comparing, under same power, rotating speed is high, and noise is low, and good aerodynamic quality, air quantity is large, and radiating effect is better.
Description
Technical field
The present invention relates to a kind of radiation fan, the axial fan that particularly a kind of pneumatic property is good.
Background technique
The advantages such as axial fan is little owing to having volume, easy for installation, have been widely used in the use of the fields such as electronic equipment, power apparatus, electric welding machine, numerical controlled machinery as ventilation and heat.
Along with developing rapidly of industry, the requirement in technological innovation improves gradually, and both required that fan can efficiency improve, reduce noise, requirement can improve rotating speed again, increases air quantity; But existing axial fan designs unreasonable due to blade shape, make the shortcomings such as fan noise is large, electric current is unstable, and rotary speed unstabilization is fixed.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, provide a kind of in aerodynamic quality, noise level, rotating speed aspect has the axial fan of comprehensive advantage, this fan is by the yardstick to blade, and geometrical shape and quantity carry out appropriate design, and when fan is run, noise is low, rotating speed is high, and smoothness can not vibrate well.
Technological scheme of the present invention is achieved in that
A kind of axial fan, comprise motor, impeller, the all identical blade of multiple shape, size is circumferentially evenly distributed with at impeller outer, the diameter of impeller is 98mm, the sweepforward angle of blade is increased in nonlinear Distribution to blade tip gradually by blade root, the sweepforward angle of blade root is 0 °, and the sweepforward angle of blade tip is 3.5 °; The chord length of described blade to be increased gradually to blade tip by blade root and linearly distributes, blade root chord length is 45.5mm, and blade tip chord length is 48.5mm, and the established angle of blade reduces in nonlinear Distribution by blade root to blade tip gradually, blade root established angle is 30 °, and blade tip established angle is 28.5 °.
As preferably, the torsional centre in each cross section of blade is placed in the mid point of the string of a musical instrument, and the torsional centre line of blade is curve.
As preferably, the number of described blade is 9.
The present invention that have employed technique scheme, by having carried out rational design to blade shape, quantity, windup-degree etc., makes its fan in the past of comparing, under same power, rotating speed is high, and noise is low, and good aerodynamic quality, air quantity is large, and radiating effect is better.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 be Fig. 1 B-B to blade line style enlarged view.
Embodiment
The specific embodiment of the present invention is as follows:
Embodiment: a kind of axial fan of the present invention, as shown in Figure 1, comprises motor 1, impeller 2, the diameter of described impeller 2 is 98mm, motor 1 is micro motor, and impeller 2 center is connected with motor 1, is circumferentially evenly distributed with all identical blade of 9 plate shapes, size 3 at impeller 2; Blade 3 is main bodys of fan, its physical dimension, and profile and the performance of blade quantity to fan have decisive influence, in order to improve fan efficiency simultaneously, reduces fan noise, and increase air quantity and improve radiating effect, blade of the present invention has following feature:
(1), the chord length of described blade to be increased gradually to blade tip by blade root and linearly distributes, and blade root chord length is 45.5mm, and blade tip chord length is 48.5mm; Adopt above-mentioned shape to be not only conducive to alleviating the weight of blade, be more conducive to the heavy burden reducing impeller, the aerodynamic efficiency of fan is improved.
(2), the established angle of blade is the angle between the string of a musical instrument in each cross section of blade and plane of rotation, the cross section of the blade 3 at different radial distances place of the present invention has different established angles relative to plane of rotation, namely blade 3 has relative torsion, the established angle of blade 3 reduces in nonlinear Distribution by blade root to blade tip gradually, blade root established angle is 30 °, and blade tip established angle is 28.5 °, thus makes each cross section of blade 3 all be in efficacious workaround under fan design state.
(3), as shown in Figure 1, the torsional centre 5 in the same each cross section of blade 3 is as the mid point of the string of a musical instrument 6, the line of each cross section torsional centre is torsional centre line 4, the torsional centre line 4 of blade of the present invention is curve, torsional centre line 4 forms sweepforward angle relative to the line between the axle center of fan and blade 3 root torsional centre, and the sweepforward angle of blade root is 0 °, and the sweepforward angle of blade tip is 3.5 °.
Claims (3)
