In, in order to provide the radiator fan of predetermined heat dissipation effect, then must matching design be more compactization equally, can answer smoothly
Electronic installation or electronic machine for miniaturization.
Refer to shown in Fig. 1 and Fig. 2, for No. I293106 " thin fan " patent of invention of TaiWan, China, this patent of invention
Disclosing a kind of existing radiator fan 8, this radiator fan 8 comprises pedestal 81, impeller 82, a piece of shape Magnet 83 and an axostylus axostyle
84.Wherein this pedestal 81 is provided with axis hole 811 and a coil groups 812；This impeller 82 has several bending flabellum 821；This sheet shape
Magnet 83 is incorporated into bottom this impeller 82；One end of this axostylus axostyle 84 is rotatably engaged the axis hole 811 in this pedestal 81, the other end
In conjunction with this impeller 82.Whereby, the impeller 82 of this existing radiator fan 8 designs for slimming, for being installed in various miniaturization electricity
In sub-product.
The impeller 82 of above-mentioned existing radiator fan 8 is generally and molds the metallic plate with impeller shape with impact style
Sheet, then be matched with this metal sheet outer peripheral edge and be bent to form several blades of predetermined angular.But, although this existing impeller 82 energy
Enough utilize metal sheet to reach miniaturized design, but the making molding mode of this existing impeller 82 is complex, and must use
Too much metal material, therefore, relatively easily causes the increase of this existing impeller 82 manufacturing cost, and utilizes metal sheet institute curved
The shape of several blades that folding is formed does not tends to have too many change.Furthermore, it is more all metal material due to this impeller 82 overall structure,
Therefore when this impeller 82 rotates, load improves the most relatively, easily affects overall operation efficiency.It addition, this existing impeller 82 periphery
Each blade angle that edge is bent to form is difficult to completely the same, it is easier to affects the carminative effects of this existing impeller 82 and rotates flat
Weighing apparatus property.
Also, as it is shown on figure 3, be No. M350746 " slimming fan propeller " new patent case of TaiWan, China, this Patent Case
Disclose another kind of slimming fan wheel structure design more typically.Wherein this Patent Case discloses a fan propeller 9, this fan propeller 9
Having a metal shell 91, these metal shell 91 central authorities combine an axle center 92, and the perisporium one of this metal shell 91 is to profile
Becoming a metal blade support 93, this metal blade support 93 combines and fixes a plastics flabellum portion 94；Whereby, this fan propeller 9 is main
Want structure to consist of metal shell 91 and metal blade support 93, therefore preferably structural strength can be possessed, and this fan propeller 9 is used
With the structure of wind dispelling then for utilizing plastic material integrated plastics flabellum portion 94, therefore, also with molding easily, effectively
Reduce manufacturing cost and the advantage such as carminative effects is good, make this fan propeller 9 be achieved thin type tool and have better structural strength concurrently.
But, metal shell 91 central authorities (i.e. in order to the position in pivot joint axle center 92) and this metal blade of this fan propeller 9
Between the outer peripheral edge (i.e. in order to combine the position in plastics flabellum portion 94) of support 93, it is not complete planar structure, Ye Ji
The position that this metal shell 91 connects with this metal blade support 93 is the hub portion 95 in crowned, causes this metal shell 91 whole
The increase of body axial height, therefore, this fan propeller 9 when being applied to various miniaturized electronic product, this metal shell 91
Hub portion 95 is easily caused the increase of axial height, and then occupies the space that miniaturized electronic interiors of products is too much, causes electronics to produce
Product are difficult to towards miniaturization direction R & D design, therefore still have the necessity improved.
