Embodiment
See also Fig. 4 and Fig. 5, fan frame with flow-guiding stator blade of the present invention comprises the stator blade 32 of cup dolly 31, a plurality of connection this housing and this base of housing that a summary is square 30, in this housing and a plurality ofly along the circumferential direction extends out to a few conducting element 33 on these stator blades, and present embodiment ties up to and extends two conducting elements 33 on each stator blade 32 and do explanation.
This stator blade 32 is to be one wing, comprises a top-surface camber 321 and a lower surface camber 322, and these conducting element 33 main systems extend from the top of this lower surface camber 322; In addition, this conducting element 33 is not do essence with adjacent stator blade 32 to contact, and unfavorable air-flow flows to avoid occupying too many space.
See also Fig. 6 and Fig. 7, when producing air-flow when a flabellum 4 rotations, air-flow can change original flow direction by the guiding of these conducting element 33 sidewalls, and then this fans the exhaust outlet of frame 3 to concentrate outflow, can reduce the generation of the turbulence flow flied on these fan frame 3 exhaust outlets and this stator blade 32 curved surfaces, and reduce the noise that turbulent flow is produced.In addition, the design of these conducting elements 33 also can stop extraneous foreign matter to enter from the exhaust outlet of this fan frame 3, can protect the safety of fan frame 3 inner members.
See also Fig. 8, Fig. 9, another embodiment of the present invention comprises a strengthening section 331 and a diversion division 332 for this conducting element 33, this strengthening section 331 is do from the lower surface camber 322 of this stator blade 32 with this to be connected, and this diversion division 332 is to extend from the bottom of this strengthening section 331.This strengthening section 331 and has strengthened the sidewall area of conducting element 33 except the bulk strength that can strengthen this conducting element 33, can increase the effect of rectification, and air-flow can be concentrated by the sidewall guiding of this conducting element 33 and flow out this fan frame 3.
Because air-flow can flow with lower surface camber 322 along the top-surface camber 321 of this stator blade 32, this conducting element 33 also can be designed to extend from this top-surface camber 321.See also Figure 10 and Figure 11, it shows this conducting element 33 is to extend from the bottom of the top-surface camber 321 of this stator blade 32, and its rectification principle does not repeat them here as hereinbefore.Certainly, this embodiment's conducting element 33 also can extend from the top of this top-surface camber 321.
Of the present invention focusing on extended at least one conducting element on the surface of stator blade, and the sidewall of this conducting element steering flow effectively flows to, and therefore, the shape of this conducting element size also need not special restriction.As Figure 12 and shown in Figure 13, this conducting element 33 is that the top-surface camber 321 from this stator blade 32 extends, and strengthens sidewall area for increasing the water conservancy diversion effect; Wherein the end face that facings the wind of this conducting element 33 is one along the plane of inclination of air current flow direction, can reduce the loss of air current flow.Be flabellum in response to different size, size and shape, with and the size and the direction of the air-flow that driven, the size and shape of conducting element is also different, is principle not influence discharge quantity of fan.
The above only is preferred embodiment of the present invention, and the foregoing description only is to be used for explanation but not in order to limiting claim scope of the present invention, and category of the present invention system is defined by appending claims.All equalizations of doing according to claim of the present invention change and modify, and all should belong to covering scope of the present invention.
