Abstract

The present invention relates to a kind of fan frame with flow-guiding static blades and its fan. It is mainly characterized by that between static blades of said fan frame a shaped flow-guiding component is set, the combination of said static blade and said flow-guiding component can make air flow be more smoothly flowed, can reduce the production of turbulent flow, raise radiation effect and can reduce noise produced by turbulent flow.

Description

Fan frame and fan with flow-guiding stator blade

Technical field

The present invention system is about a kind of fan frame and fan with wing stator blade and conducting element about a kind of fan frame and fan with flow-guiding stator blade especially.

Background technique

Common shaft streaming fan frame comprises the base 11 of a housing 10, in this housing 10 and the stator blade 12 of this housing 10 of a plurality of connection and this base 11 as shown in Figure 1.Please consult Fig. 2 simultaneously, when this known fan frame 1 collocation flabellum (not illustrating among the figure) operated, the air-flow that this flabellum drove can produce turbulent flow at this exhaust outlet place that fans frame 1, cause air-flow effectively to dispel the heat at thermal source; Tie up to especially when operating under the high back pressure, the air-flow that flabellum produced more can produce turbulent flow on stator blade 12 curved surfaces, cause flabellum stall easily, and air-flow is effectively work done also, and can produce bigger noise.

The present invention promptly proposes a kind of fan frame of tool flow-guiding stator blade at above-mentioned defective, effectively air-guiding flows to, and makes the unlikely situation that produces turbulent flow of air-flow.

Summary of the invention

Main purpose of the present invention ties up in a kind of fan frame and fan with flow-guiding stator blade is provided, it ties up to, and the inner edge from this fan frame extends a wing conducting element between per two stator blades of this fan frame, the collocation of this stator blade and this conducting element can allow the air-flow secondary-working, reduce the generation of turbulent flow, make by the flow field of stator blade curved surface more smooth and easy, increase heat dissipation, and can reduce the noise that turbulent flow is produced.

For achieving the above object, fan of the present invention comprises that a fan frame and is arranged at the impeller sets of this fan frame inside.This fan frame comprises stator blade and a plurality of conducting element that extends to the center from this housing inner edge of base, a plurality of connection this housing and this base of a housing, in this housing.Wherein this conducting element is a wing-shaped structure and does not contact with this base essence, and it is to work in coordination with the shape of this stator blade, makes the air-flow of this stator blade of flowing through can secondary-working, to reduce the generation of turbulent flow.The design of these conducting elements also can stop extraneous foreign matter to enter from the exhaust outlet of this fan frame in addition, can protect the safety of fan frame inner member.

For above and other objects of the present invention, feature and advantage can be become apparent, a preferred embodiment cited below particularly, and conjunction with figs. are described in detail below:

Embodiment

See also Fig. 3, the fan with flow-guiding stator blade of the present invention comprises that a fan frame 3 and is arranged at the impeller sets 2 of these fan frame 3 inside, and this impeller sets 2 has a plurality of skewed blades of the type of raising up that are.This fan frame 3 comprises stator blade 32 and a plurality of conducting element 33 that extends to the center from the top of this housing inner edge 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 wherein these stator blades 32 are that each interval is arranged with these conducting elements 33.

This stator blade 32 and this conducting element 33 all are to be one wing, but this conducting element 33 is the air quantity that contact with these base 31 essence to avoid excessive influence to export from this fan frame 3; In addition, the height of this conducting element 33 preferably is 1/4th to 3/4ths of these stator blade 32 height.

Please consult Fig. 4 simultaneously, when producing air-flow when these impeller sets 2 rotations, air-flow can be mobile along the curved surface of these stator blade 32 tops or this conducting element 33 earlier, the wing curved surface of this conducting element 33 can further be guided air-flow the bottom that carry over this stator blade 32 and be flowed, so can reduce the generation of the turbulence flow flied on these fan frame 3 exhaust outlets and this stator blade 32 curved surfaces, and can 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. 5, another embodiment of the present invention is to extend to the center from the bottom of these housing 3 inner edges for these a plurality of conducting elements 33, and other structure characteristic and identical with connection relationship such as the above embodiments of other element repeats no more.

Please consult Fig. 6 simultaneously, when producing air-flow when these impeller sets 2 rotations, air-flow can be mobile along the curved surface of this stator blade 32 earlier, then at this air-flow with confusion reigned before the irregular turbulent flow, guiding by the wing curved surface of this conducting element 33, make this air-flow can carry over the Lower Half of curved surface of this stator blade 32 or the curved surface of this conducting element 33 flows, with generation that reduces turbulent flow and the noise that is produced thereof.Similarly, 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.
