Embodiment
See also Fig. 2 A to Fig. 2 C, it shows first preferred embodiment of sink of the present invention.Be to be example in this embodiment, but its design also can be applicable on the axial flow fan with a centrifugal fan.This centrifugal fan is the blower of a unidirectional wind input type, and it mainly comprises one first framework 21, one second framework 22, a drive unit 23, an iron-clad 24 and a movable vane portion 25.This first framework 21 has a receiver 211, makes this drive unit 23 thereon bearable, and a bearing 231 is placed the rotating shaft 27 to support this movable vane portion 25 in this receiver 211.This second framework 22 has a wind inlet 221 and from the downward wall 222 that extends of wind inlet inner edge, after this second framework 22 and this first framework 21 make up, this second framework 22 and this formed separated by spaces in first framework, 21 combination backs are limited the space of a gas collection runner 26 and ccontaining this movable vane portion 25 by this wall 222, also form an exhaust outlet 212 simultaneously.This wall bottom has a flange that extends radially outwardly 223, in order to limit an inlet 261 of this gas collection runner.
This movable vane portion 25 is driven by this drive unit 23, and constituted by a ring portion 251, a base plate 252, one first flabellum group 253 and one second flabellum group 254, this the first flabellum group 253 and the second flabellum group 254 all are made up of a plurality of blade, wherein this first flabellum group 253 is to extend downward this base plate 252 surfaces from the periphery of this ring portion 251, and this second flabellum group 254 then is arranged on this base plate 252.The arrangement mode of this first flabellum group 253 and the second flabellum group 254 can be staggered to be arranged, shown in Fig. 2 A.
The wind inlet place of this second framework 22 also is provided with a base portion 224, and has a plurality of flow guide structures 225 and be arranged between this base portion 224 and this wall 222, in order to improve the blast of this centrifugal fan.
When this centrifugal fan running, air-flow is after this wind inlet 221 is inhaled into, this the first flabellum group 253 and the second flabellum group 254 through this movable vane portion, and via the ingress 261 that is positioned at this gas collection runner 26 guiding enters this gas collection runner 26, pressurize and gas storage, to avoid the variation rapidly of blast, discharge the air-flow of high blast again from this exhaust outlet 212.
In this embodiment, the wall that the wind inlet edge of this centrifugal fan extends downwards is in order to separate this gas collection runner 26 and this movable vane portion 25, only stay a less exhaust outlet, the pressure process of the air stream of feasible this movable vane portion that flows through is elongated, can avoid the variation rapidly of pressure.This movable vane portion axially on, the height of this gas collection runner and flow through this movable vane portion and the true runner height of flow guide structure can be overlapping partially or completely, make this centrifugal fan can reach purpose of thinness.And the sectional area of this gas collection runner 26 is equal to the sectional area of this exhaust outlet 212 in fact, can avoid the change of air-flow because of area thus, and makes work doing efficiency reduce.
In addition, the present invention adopts the reversing motor Fixed Design, shown in Fig. 2 C, in a bearing 231 being placed this receiver 211, other establishes base portion 224 inboards of a bearing 232 in this second framework 22, with the rotating shaft 27 of this movable vane portion 25 of together support, the stability that fan runs up to be provided and to reduce the generation of vibrations.In addition, the present invention also adopts 29 designs of axial compression formula air channel, shown in Fig. 2 C.
Certainly, size, shape and the configuration mode of this first flabellum group 253 and the second flabellum group 254 comprises the two kinds of flabellum group designs that have that are not limited to shown in Fig. 2 A, and the combined type flabellum design of this movable vane portion also can have the flabellum design of two or more at least flabellum groups.And the number of blade of various flabellum groups, shape and size can be identical or different.On alignment arrangements, can be interconnected with one another between each flabellum group in this combined type flabellum, part connects or do not connect application fully, and each flabellum group can be with same side or the opposition side that list in this movable vane portion.For instance, see also Fig. 3 A, this first flabellum group 353 and the second flabellum group 354 can be up and down configuration, this first flabellum group 353 be located on this ring portion 351 around, be wings; And this second flabellum group 354 is located on the surface of this base plate 352, and every blade presents not contour bent arc curved shape structure, and promptly each blade has different leaf margin height.Size, shape and the number of blade of this first flabellum group 353 and the second flabellum group 354 are inequality.This ring portion 351, this base plate 352, this first flabellum group 353 and the second flabellum group 354 can one-body molded mode molding and forming.Perhaps, this base plate 352 and these first flabellum group, 353 first integrated injection moldings, this ring portion 351 and the also first integrated injection molding of the second flabellum group 354 are combined into both a complete movable vane portion at last again.In addition, combined type flabellum design of the present invention also can be shown in Fig. 3 B, and this first flabellum group 353 is interconnected with one another with the second flabellum group 354 is in the same place, and both are bent arc curved shape, and bending direction presents opposite direction.Yet the design of any variation and modification does not still break away from claim of the present invention.
Except above-mentioned flow guide structure is disposed at the mode at wind inlet place, similarly flow guide structure 28 also can be arranged at exhaust outlet 212 places in addition, as shown in Figure 4, be an arc shape structure, and the number of this flow guide structure, shape and configuration mode can be done different selections and variation according to practical application.In addition, if when conception of the present invention is applied to a reversely hung Yong centrifugal cutter, two-way wind input type blower or axial flow fan, this flow guide structure structure can be arranged at a wherein wind inlet place, or is arranged at each wind inlet place simultaneously, and two movable vane portions can be set in it.
At last, see also Fig. 5, it is air quantity and the blast characteristic comparison diagram of first preferred embodiment of sink of the present invention (being shown in Fig. 2 A to Fig. 2 C) with existing blower (being Fig. 1), figure can know the design of demonstration sink of the present invention by the combined type flabellum thus, can increase its fluid property, increase substantially the blast and the air quantity of sink.
Described above comprehensive, the invention provides a kind of sink of using the design of combined type flabellum, it can increase its fluid property, and then reaches the characteristic that increases blast, to increase substantially radiating efficiency.
So the present invention must be thought and is to modify as all by person skilled in the art Shi Renshi craftsman, all should not break away from as the claimed scope of appended claim.
