Time, noise increase becomes apparent from, and in view of this, needs to be optimized fan of car air conditioner improvement, reduces noise.
Summary of the invention
For solving above technical problem, the present invention provides a kind of air conditioning for automobiles denoising draught fan assembly.
Technical scheme is as follows:
A kind of air conditioning for automobiles denoising draught fan assembly, including bellows and the centrifugal wind wheel being arranged in these bellows, described bellows
The described centrifugal wind wheel of upper correspondence is provided with fan air inlet, and it it is critical only that: be provided with a ring shape fall around described fan air inlet
Making an uproar groove, the opening of this annular noise reduction groove is towards the blade support ring of described centrifugal wind wheel, the blade support ring of described centrifugal wind wheel
Near this annular noise reduction groove.
The remarkable result using above technical scheme is that centrifugal wind wheel includes just to the driving dish arranged and blade support
Ring, circumferentially distributed between driving dish and blade support ring have multiple blade, and blade one end is connected with blade support ring, the other end with
Driving dish connects, and drives disk center position to be provided with drive shaft jack, when driving dribbling moving vane and blade support ring to rotate, and air-flow
Entering inside blade support ring, dissipate blowout from blade outboard, the air-flow major part of blowout radially blows away along centrifugal wind wheel, and
Axially blowout can be partial to from the air-flow blown out near blade edge (near blade support ring one end)；Traditional, deflection is axially blown
The air-flow gone out directly clashes into the most close Blower Housing, thus sends sound；And in this case, the gas of deflection axially blowout
Stream can enter in annular noise reduction groove, increases air-flow stroke, mitigation of gases flow velocity, reduces the impact with Blower Housing, thus reduce
Noise.
The blade support ring of above-mentioned impeller is arranged circumferentially at the notch of described annular noise reduction groove.This design can make deflection axle
Air-flow to blowout refluxes, and reduces flow velocity further, reduces noise.
The bottom land of described annular noise reduction groove is curved.The air current flow that this design can make deflection axially blow out is more smooth and easy.
The noise reduction inner core along same cylinder heart line suit and noise reduction urceolus it is provided with, in described noise reduction in above-mentioned fan air inlet
Connecting ring by noise reduction between cylinder and the same end margin of noise reduction urceolus to connect, described noise reduction inner core, noise reduction urceolus, noise reduction connect
Collar becomes described annular noise reduction groove, and the outer wall of described noise reduction inner core and the edge of described fan air inlet are fixing to be connected, described from
The blade support ring of heart-wind syndrome wheel is between described noise reduction inner core and noise reduction urceolus.Use this design, noise reduction inner core, noise reduction urceolus
Connect ring with noise reduction can directly set up in fan air inlet, vary without bellows original structure.
Above-mentioned noise reduction connects the outside of ring and is provided with a circle air inlet pipe card T-Ring, and the diameter of this air inlet pipe card T-Ring is more than described
The diameter of noise reduction inner core.Air inlet pipe card T-Ring in the program is used for connecting air inlet pipe, makes air inlet pipe inwall and noise reduction inner core
Interior walls be smooth transition.
Above-mentioned bellows include the upper volute that mutually fastens and lower spiral case, and described fan air inlet is opened in described upper volute
On, described noise reduction inner core, noise reduction urceolus, noise reduction connect ring and upper volute is one-body molded, and described lower house is provided with motor assembly,
The driving dish of described centrifugal wind wheel is arranged on the output shaft of this motor assembly.
Beneficial effect: use the air conditioning for automobiles denoising draught fan assembly of the present invention, by going out to arrange annular at air inlet
Noise reduction groove, the air-flow of deflection axially blowout enters in annular noise reduction groove, increases air-flow stroke, mitigation of gases flow velocity, reduces and wind
The impact of casing body, thus reduce noise.
