Description
Technical field
The present invention is about a kind of radiation fan and impeller thereof, and especially a kind of design has the impeller of special construction, to be applicable to the axial flow fan that two-way wind dispelling function is provided.
Background technique
Common on the market existing axial flow fan roughly has a housing at present, in conjunction with as members such as a stator and impellers, so that utilize this stator to drive this impeller rotation start, and then can reach predetermined wind dispelling amount in this housing.
The impeller of aforementioned existing axial flow fan is roughly announced " the impeller blade structure of small heat-dissipating fan " novel patent No. 254381 as TaiWan, China.Please refer to shown in Figure 1, should have a circular base plate 81 by existing impeller 8, these circular base plate 81 peripheries form a cavity ring 82, the outer perimeter wall of this cavity ring 82 forms several blades 83, respectively this blade 83 is the arc concave shape, make respectively that a side of this blade 83 forms a reentrant part 831, the another side forms a bump 832.Whereby, when this existing impeller 8 be applied to existing axial flow fan and driven by this stator and the rotation start when producing air-flow, because respectively the reentrant part 831 of this blade 83 can provide this air-flow one pressure accumulation effect, therefore, existing impeller 8 with this reentrant part 831 as the wind dispelling face, so that produce bigger air quantity.
And, the application of existing axial flow fan is quite extensive, as needs heat radiation, ventilation, air draft, ventilation or temperature control, or even conveying on processing procedure or control of dust operation, and air-conditioning in life, smoke evacuation and other specific uses etc., all need to be applied to this existing axial flow fan.In addition, existing axial flow fan is in aforementioned cited various uses, for satisfying various work requirements, existing axial flow fan also may must be controlled this impeller 8 and be rotated in the forward or counterrotating, make this impeller 8 have two-way wind dispelling function (referring to that at this air-flow can select to produce air quantity towards different direction on axially), so that need to be applied to the workplace of two-way wind dispelling.
Yet, though needing the workplace of two-way wind dispelling must control this existing impeller 8 at some is rotated in the forward or counterrotating, so that reach the function of two-way wind dispelling, but, each blade 83 of existing impeller 8 forms this reentrant part 831 because only having a side, also promptly existing impeller 8 only when utilizing this reentrant part 831 as the wind dispelling face, can provide this air-flow one pressure accumulation effect; Therefore, should have impeller 8 reality now in the process of two-way wind dispelling,, will not have the pressure accumulation effect owing to this bump 832, and cause the wherein wind dispelling poor effect of a direction during as formed this bump 832 in another side of desiring to utilize by force this blade 83 respectively as the wind dispelling face.
For instance, as No. 97135371 " light fixture " patent of invention of TaiWan, China application, promptly be to be applied to light fixture and to carry out two-way wind dispelling function by existing impeller 8 with automatic dedusting function.Please refer to shown in Figure 2ly, this existing light fixture 9 comprises a shell 91, an impeller 92, a light-emitting component 93 and a control unit 94.This shell 91 has an inlet section 911 and an outlet section 912; This impeller 92 has several blades 921, because this impeller 92 is identical with the structure characteristic that aforementioned existing impeller 8 is disclosed, it is the same reentrant part (not indicating) that forms in a side of this blade 921 respectively, the another side is same to form a bump (not indicating), and can not drive this impeller 92 rotation starts by a stator (illustrating) equally; This light-emitting component 93 is in conjunction with a side of this impeller 92; This control unit 94 is in order to control this impeller 92 counterrotatings, and so that a heat sinking function to be provided, perhaps also this impeller 92 of may command is rotated in the forward, so that dedusting function to be provided.
In more detail, as shown in Figure 2, when these control unit 94 these impeller 92 counterrotatings of control, this impeller 92 can be from this inlet section 911 be introduced air-flows so that after dispelling the heat at this light-emitting component 93, further make again this air-flow via this outlet section 912 with heat transfer to extraneous space, whereby, because during these impeller 92 counterrotatings, with the formed reentrant part in a side of this blade 921 (indicating) respectively as its wind dispelling face, so still can produce predetermined air quantity.Shown in Figure 3 in addition, when these control unit 94 these impellers 92 of control are rotated in the forward, though this impeller 92 still can order about the air-flow adverse current of these housing 91 inside, and further via this inlet section 911 with this gaseous emission to these housing 91 outsides, so that this air communication is crossed in the process of this inlet section 911, can remove the dust that is deposited in this inlet section 911 simultaneously; But because this impeller 92 is when being rotated in the forward, respectively the another side of this blade 921 there is no reentrant part with as the wind dispelling face, so cause that these impeller 92 air-guidings are reverse can't to produce enough air quantity during by this inlet section 911.Generally speaking, the impeller 8,92 of existing axial flow fan still is necessary to be improved, and makes it more be applicable to two-way wind dispelling function, so that need to be applied to the workplace of two-way wind dispelling.
