The present invention relates to a kind of fan.The invention particularly relates to the fan wheel in a kind of fan of in Motor Vehicle, using.
Existing technology
In ventilation or air-conditioning fan, usually use to have the fan of semiaxis to fan wheel, this fan wheel can have higher efficient with respect to pure axial and pure radial fan wheel.Semiaxis is axial and the combination of radial fan wheel to fan wheel.The axial component of this fan wheel sucks the air that will carry according to the mode of propeller cavitation from the direction that is parallel to running shaft.The radial component of this fan wheel is radially discharged inhaled air according to the mode of centrifuge.
For will pass through semiaxis to the air deflection of the axial component of fan wheel to radial component, in the zone between these two parts diverter element is set.Diverter element is fixed on the fan motor and for example usually can have conical by its shape.Semiaxis abuts on the fixing diverter element to the outflow blade that extends diametrically of the axial component of fan wheel, so that reduce the formation of frictional loss and noise.Through a certain proportion of suction air of overflowing of the gap that limits thus between end that flows out blade and diverter element, rather than all through radially leaving fan wheel flowing out between the blade.This semiaxis is lower than a possible maximum value thus to the efficient of fan wheel.
Disclosure of an invention
Therefore task of the present invention is to propose a kind of fan wheel, and it overcomes said defective and makes easily in addition.
This task solves according to the fan with fan wheel of claim 1 with through a kind of Motor Vehicle according to claim 10 through a kind of.Dependent claims provides favourable or possible supplementary features.
According to first aspect, the fan wheel of fan comprises and has the suction blade that gets into rim, gets into the axial inlet direction of rim facing to fan wheel; And have the outflow blade that flows out rim; Flow out the radially Way out of rim facing to fan wheel, and diverter element, it is used for air is deflected into the active region of flowing out blade from the active region that sucks blade; Wherein, diverter element with at least one flow out blade shape ordinatedly and/or power transmission be connected ordinatedly.
Different to fan wheel with known semiaxis, this diverter element is followed fan wheel rotatablely moving with respect to fan motor.Diverter element flows out to allow being connected of blade to eliminate with at least one and is flowing out the gap between blade and the diverter element and therefore be responsible for making the air of outflow when flowing out, positively to obtain the direction and the speed of hoping.Especially can be with a plurality of or all flow out blade and be connected with diverter element, thus the air that all flows out must pass through flowing out between the blade.
At least one sucks blade can constitute one with the outflow blade.In one embodiment, the suction of combination and outflow blade can have the part of suction and flow out part.One in the interface of the suction of this combination and outflow blade can partly or on whole length abut on the diverter element.The quantity that flows out blade also can be greater than or less than the quantity that sucks blade.For example, can additionally in fan wheel, construct the outflow blade of other dispersion except the suction of combination with the outflow blade.In one embodiment, fan wheel comprises the outflow blade of twice of the air blades of combination.In the corresponding way, the quantity of suction blade also can surpass the quantity that flows out blade.
Diverter element can be connected with the outflow blade by means of be connected (mechanism).This is favourable when making fan wheel in a large number especially, and the form fit connection or the power transmission that wherein just should form between diverter element and the outflow blade through a simple process step are connected.This be connected (mechanism) for example can have draw pin and with its corresponding concave part.Therewith alternatively, diverter element for example can have continuous rim, and a plurality of outflow blades are engaged to this rim the inside.Can and flow out also that the form fit that realizes other between the blade connects or power transmission is connected at diverter element, for example engaging (linkings), bonding, rivet, be threaded, welding, soldering, wedging or clog.
Suck blade and flow out the element that blade can form an one of fan wheel.The element of this one can additionally have wheel hub and/or reinforcing element, and these reinforcing elements are followed side face or all facial contours of fan wheel.In one embodiment, reinforcing element comprises a hollow cylinder part, and it is diametrically outwards to sucking the blade gauge.
The element of this one can not have side recessed (undercut construction) aspect a parting surface with the running shaft radial symmetric.For example, the element of one can be made in permanent mo(u)ld in casting or extrusion process, and this permanent mo(u)ld can separate along parting surface, thereby the element of this one can take out (molding) from this permanent mo(u)ld.Parting surface can be the part on a plane vertical with running shaft.Through the parting surface of selection with the running shaft radial symmetric, can so advantageously design the element of this one, make that when molding from permanent mo(u)ld, sucking blade is not hindered with the outflow blade.Possible be used to strengthen fan wheel structure,, also so be shaped, make them not hinder molding like for example wheel hub or reinforcement face.Can use a permanent mo(u)ld in order to produce a large amount of fan wheel thus, it only comprises two parts and does not have slide plate (Schieber).
Fan can comprise a fan motor with axle of supports fans wheel in addition, and wherein, driving moment is delivered on the fan wheel from fan motor by means of diverter element.Fan wheel for example can be injected into that axle is gone up or axle be positioned at the holding on the body of hub side.Axle can be connected with the stator or the rotor of fan motor, and wherein, axle can be rotatably mounted by end ground or ground, two ends.This especially can be arranged between stator or the rotor of fan wheel and fan motor and transmit shearing force, bending force, pulling force and/or thrust, and does not participate in the transmission of the driving moment from the fan motor to the fan wheel.Through by means of diverter element driving moment being directed in the fan wheel, driving moment needn't be delivered to the outflow blade by means of sucking blade, and therefore sucking blade can optimally be shaped to the profitability that flows, and does not receive the influence of requirement of strength.
Fan motor can comprise the external rotor (external rotor) that is connected ordinatedly with the diverter element power transmission.Because the structural type of this external rotor, driving moment can and running shaft between big radial spacing under be applied in the diverter element, wherein lever is very little, is the very little structural load of diverter element maintenance thus.Additionally, the stator of the fan motor that is surrounded by external rotor can be filled the space on fan wheel one side that deviates from of diverter element best, thereby fan can be constructed especially compactly.
External rotor can comprise one or more permanent magnets.Because and the running shaft of fan wheel between bigger spacing under the bigger quality of permanent magnet, the rotatory inertia of fan wheel is very high, the rotation of fan wheel is by damping and more even thus during driving through fan motor.Therefore during the drive fan wheel, reduce generating noise through the staor winding that alternately activates.
According to second aspect, a kind of Motor Vehicle comprises the fan with said fans wheel.
