Abstract
A kind of aerofoil fan, including framework, blower fan is provided with the framework, the blower fan includes the stator being fixedly connected with the framework, the rotor being arranged on the stator, and the fan blade being fixedly installed in the rotor circumference, air intake vent of the stator close to the framework, for the rotor close to the air outlet of the framework, the air intake vent side that the stator is located at the framework is provided with chamfering.The present invention forms the moving air that part is affixed on rotating shaft at fan shaft, for taking away heat caused by rotating shaft.
Description
Technical field
The present invention relates to a kind of fan, more particularly to the aerofoil fan that a kind of thermal diffusivity is good.
Background technology
Cooling fan for cooling down heat-generating electronic part can be carried by being in electrical article, OA, IT equipment.In recent years, exist
In the market, these family's electrical articles, the miniaturization of OA, IT equipment, high performance promote.With the miniaturization, high-performance
Change, the densification of the electronic unit in being constructed due to device interior, the caloric value from electronic unit has increased trend.
For the caloric value increase from electronic unit, as fan, generally use is small-sized and is easily obtained the small of air quantity
Profile shaft flow fan.But in the case where being cooled down using small axial flow fan, in order to obtain desired cooling air quantity,
Fan must be made to rotate at a high speed, cause fan self-heating serious, influence radiating efficiency, while reduce the life-span of fan.
The content of the invention
The present invention is solution prior art problem, there is provided a kind of good aerofoil fan of self-radiating effect.
The technical scheme is that：A kind of aerofoil fan, including framework, blower fan, the wind are provided with the framework
Machine includes the stator being fixedly connected with the framework, the rotor being arranged on the stator, and is fixedly installed on the rotor
Fan blade on circumference, the stator close to the framework air intake vent, the rotor close to the framework air outlet, it is described fixed
Son is provided with chamfering positioned at the air intake vent side of the framework.
Preferably, the fan blade is fixedly installed on the outer surface of the rotor；The rotor outer surface is located at adjacent institute
State and be provided with some wind grooves parallel with the fan blade between fan blade.
Preferably, the chamfering of the stator extends to the porch of the wind groove to the rotor.
Preferably, the spacing between the adjacent wind groove is equal.
Preferably, the rotor is located at the fan blade and the rotor between the termination of the framework air outlet
External diameter axially gradually reduces along the rotor to framework air outlet direction extension.
Preferably, the minimum outer diameter of the rotor is not less than the 1/2 of maximum outside diameter.
Aerofoil fan for lifted air quantity, it is necessary to lift rotating speed, it is big by the air quantity of fan in itself after rotating speed is lifted
Increase, but due to the structure problem of conventional axial-flow fan itself, air quantity is minimum at the rotating shaft of maximum of generating heat, and causes fan itself to produce
Heat can not shed, traditional aerofoil fan can not still solve this problem so far, cause aerofoil fan not provide
The product of high-power, high air quantity.
Because the wind direction of traditional aerofoil fan is to blow to rotor by stator, therefore the present invention is in the stator of aerofoil fan
Output chamfering in front end so that at work, during exhausting, most of air passes through fan blade to aerofoil fan from framework hollow part
Air outlet is pushed to, has fraction air to form flow-disturbing in fan front by stator barrier, after having fraction air by chamfering
Pass through along rotor outer surface, due to the presence of flow-disturbing so that continued along chamfering through the air that rotor outer surface passes through by one
Thrust, and because this partial air have passed through chamfering, so this partial air and being directly over what the air of fan blade flowed through
Path is compared to elongated, and relative to the air for being directly over fan blade, air velocity of this part Jing Guo chamfering is slower, therefore can be passed through
The air for crossing fan blade is repelled, by the thrust of a sensing rotor outer surface so that air of this part Jing Guo chamfering is close to
Pass through in rotor outer surface, effectively take away heat caused by rotor.
Due to the rotation of rotor so that it is not simple linear motion by the air of chamfering and rotor outer surface, but
It is threadingly advanced, additional stator front end flow-disturbing and the high-speed air influence by fan blade, easily causes the sky of this part auxiliary heat dissipation
Gas forms sinuous flow, reduces radiating effect.It is preferred, therefore, that some wind grooves can be set in the outer surface of rotor, for guiding air
Flowing, ensure that radiating effect, while wind groove can also increase the surface area of rotor, improving radiating effect.
The rear end of rotor sets the inclined plane that an external diameter gradually reduces, for expanding the air cross-sectional area that radiates, equally
The air of quantity, cross-sectional area expand, then air pressure must reduce, and low pressure produces to follow-up air and draws effect, heat radiation
The flow velocity of air.Cause the overall axle of aerofoil fan to form the shape of similar fairing simultaneously, reduce the windage of axle in the gas flow,
The air quantity of aerofoil fan is lifted on the premise of equal-wattage.
In summary, the present invention has advantages below：
1st, the moving air that part is affixed on rotating shaft is formed at fan shaft, for taking away heat caused by rotating shaft；
2nd, there is higher blast under equal-wattage.
