Abstract

A kind of fan module, including an aerofoil fan, aerofoil fan be respectively arranged at two ends with a vent, a trousers it is provided with at least one vent, this aerofoil fan includes one being positioned at the wheel hub at center, enclosing the some blades and being located at around wheel hub and be sheathed on the sleeve of blade periphery, this trousers includes the cover body of a taper and some stators, cover body little rectify countershaft flow fan vent and between sleeve and wheel hub or just to flabellum, the big end of this cover body is fixed in one end of these stators, and the other end of these stators is fixed on sleeve.Comparing prior art, the trousers of the taper of said fans module can reduce the interference that the blade of fan is caused by the turbulent flow at vent, in the case of not changing fan structure, can effectively reduce the noise of fan.

Description

Fan module
Technical field
The present invention relates to a kind of fan module.
Background technology
In electronic system, the air-flow of fan inlet end can be disturbed by the layout of front mechanism member and soft copy, it is easily formed irregular turbulent flow and enters fan, fan leaf is made to produce noise, additionally the pressure change of air-flow moment at fan outlet will also result in extra noise, not only operator are caused puzzlement by these noises, under suitably not controlling, possibly even affect the running of system inner assembly.
Summary of the invention
In view of the foregoing, it is necessary to a kind of fan module being beneficial to reduce noise is provided.
A kind of fan module, including an aerofoil fan, aerofoil fan be respectively arranged at two ends with a vent, a trousers it is provided with at least one vent, this aerofoil fan includes one being positioned at the wheel hub at center, enclosing the some blades and being located at around wheel hub and be sheathed on the sleeve of blade periphery, this trousers includes the cover body of a taper and some stators, cover body little rectify countershaft flow fan vent and between sleeve and wheel hub or just to flabellum, the big end of this cover body is fixed in one end of these stators, and the other end of these stators is fixed on sleeve.
Comparing prior art, the trousers of the taper of said fans module can reduce the interference that the blade of fan is caused by the turbulent flow at vent, in the case of not changing fan structure, can effectively reduce the noise of fan.

Fig. 2 is the three-dimensional installation diagram of fan module of the present invention.
Fig. 3 is the Fig. 2 sectional view along III-III direction.
Main element symbol description
Following detailed description of the invention will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Detailed description of the invention
Refer to Fig. 1 and Fig. 2, fan module of the present invention includes an aerofoil fan 10 and is respectively arranged at two trouserss 20 at aerofoil fan 10 two ends.
This aerofoil fan 10 be respectively arranged at two ends with a vent 15.This aerofoil fan 10 includes one being positioned at the wheel hub 11 at center, enclosing the some blades 12 being located at around wheel hub 11 and and be sheathed on the sleeve 13 of blade 12 periphery.The two ends of sleeve 13 are the most vertically provided with two end plates 131, and the outer surface of sleeve 13 is provided with the flat part 132 of some connection two end plates 131 vertically.
Refer to Fig. 1 and Fig. 3, trousers 20 includes the cover body 21 of a taper and some outsides being arranged at cover body 21 and extends the stator 22 of the central axis being parallel to trousers 20 formed from the edge of the big end 211 of cover body 21 to the small end 212 of cover body 21, and this stator 22 is elastic sheet.
In present embodiment, wheel hub 11 is cylindric.Cover body 21 is circular cone tubular.The diameter of the big end 211 of cover body 21 is more than the external diameter of the sleeve 13 of aerofoil fan 10.The diameter of the small end 212 of cover body 21 is more than the diameter of the wheel hub 11 of aerofoil fan 10, less than the internal diameter of sleeve 13.The selection range of gradient α of the inner surface of cover body 21 is 20 degree～30 degree, and preferred angled degree is 20 degree.
Refer to Fig. 2, when trousers 20 is installed, respectively by two vents 15 of the small end 212 aiming axis flow fan 10 of the cover body 21 of two trouserss 20, making the small end 212 of cover body 21 be spaced a distance with the wheel hub 11 of aerofoil fan 10, stator 22 elasticity is connected to the flat part 132 that the outside of end plate 131 is corresponding.Glue can also be coated with bonding between stator 22 and flat part 132.The two ends of aerofoil fan 10 will be installed in by two trouserss 20.
Before air-flow enters the front end vent 15 of aerofoil fan 10, turbulent flow can be produced because of front mechanism member and the interference of electronic component, the cover body 21 of the taper of trousers 20 can produce rectified action to turbulent flow, reduces the turbulent flow impact to flabellum 12, thus reduces the front end noise of aerofoil fan 10.
When air-flow flows out the rear end vent 15 of aerofoil fan 10, can be because of the change of the stream pressure of moment, cause aerofoil fan 10 moment speedup, produce extra noise, the cover body 21 of the taper of trousers 20 can reduce the pressure change of air-flow moment, effluent stream is played cushioning effect, thus reduces aerofoil fan 10 rear end noise.
From the foregoing, it will be observed that two trouserss 21 of the circular cone tubular of fan guard 20 can reduce the air-flow impact on the performance of aerofoil fan 10 at vent 15, in the case of the structure not changing aerofoil fan 10, the noise of aerofoil fan 10 can be effectively reduced.
