Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
Characteristic on above-mentioned purpose of the present invention and structure and fuction thereof, is explained the preferred embodiment according to institute's accompanying drawings.
Figure 1A is the schematic top plan view of fan structure of the present invention; Figure 1B is the X-X sectional schematic diagram of Figure 1A; Fig. 1 C is the Y-Y sectional schematic diagram of Figure 1A.As shown in Figure 1A to 1C, fan framework construction of the present invention comprises a fan frame 10 and has the both sides that a wind inlet 101 and an exhaust outlet 102 lay respectively at fan frame 10; One runner 103 is communicated with this wind inlet 101 and this exhaust outlet 102, is provided with the inwall that a pedestal 104 connects this fan frame 10 in runner 103, and this pedestal 104 is arranged on and is positioned at this exhaust outlet 102 place; One impeller 11 to be arranged in this runner 103 and to be articulated on this pedestal 104, and this impeller 11 can operate and to enter from this wind inlet 101 with carry fluid on this pedestal 104, and then flows out from this exhaust outlet 102 through runner 103.
This fan frame 10 by multiple frame layer by layer folded or storehouse or rank group is formed, the vibration frequency difference that the material of each frame layer or composition and this material produce.The material of frame layer is plastic cement material, comprising: PBT, PA66, PPE, PA, PC, ABS, PPS etc.By ejection formation mode first by the injection of the plastic material of a frame layer in mould, then penetrate the plastic material of another frame layer, with make each frame layer by layer folded or storehouse be combined into one; Or combine with structure engaging or rivet, make each independent blocks layer be assembled into a framework.
Represent that this fan frame 10 comprises one first frame layer 14 and one second frame layer 15 in the drawings, this the second frame layer 15 along this fan frame 10 axially directly stacked or storehouse on this first frame layer 14, namely go up push-down stack as illustrated in the drawing, this the first frame layer 14 is near this exhaust outlet 102, and this second frame layer 15 is near this wind inlet 101.
Especially be noted that the first frame layer 14 is PBT (Polybutylene Terephthalate, polybutylene terepthatlate), PA66 (Polyamide66Resin; Polyamide 66), PPE (PPO＝ polyphenylene oxide), PA (Polyamide, polyamide), PC (Polycarbonate, polycarbonate resin), ABS (Acrylonitri1e-Butadene-Styrene, the styrene copolymerized compound of the fine butadiene one of propylene), PPS (Polyphenylene Sulfide Ether, polyphenylene sulfide) is wherein arbitrary, and this second frame layer 15 is PBT, PA66, PPE, PA, PC, ABS, PPS wherein another.From figure, contrast the similar and different of material for making to know, identical material uses identical hatching, and different materials uses different hatchings.This this first frame layer 14 of better enforcement is PA66 material, and the second frame layer 15 is PBT material.Implementing this first frame layer at another is as shown in Figure 2 PBT material, and this second frame layer is PA66 material.In graphic, the hatching of the first frame layer 14 and the second frame layer 15 is different.
Refer again to the first frame layer 14 shown in Figure 1A to 1C and Fig. 2 and produce one first vibration frequency; Second frame layer 15 produces one second vibration frequency; Because the material composition of this first frame layer 14 forms different from the material of this second frame layer 15, so the first vibration frequency of the first frame layer 14 is naturally just not identical with the vibration frequency of this second frame layer 15, therefore the present invention is by the plurality of different plastic cement material and the fan frame 10 that formed of the frame layer of different vibration frequency, and the fan frame 10 that can significantly reduce in the running of this impeller 11 resonates and noise situation.
As shown in Figure 3, implement at another, this fan frame 20 comprises: one first frame layer 24, and one second frame layer 25 is directly layered on this first frame layer 24 along the axis of this fan frame 20, and one the 3rd frame layer 26 is directly layered on this second frame layer 25 along the axis of this fan frame 20.This first frame layer 24 is near this exhaust outlet the 102, three frame layer 26 near this wind inlet 101, and this second frame layer 25 is between this first frame layer 24 and the 3rd frame layer 26.This first frame layer 24 produces one first vibration frequency, and this second frame layer 25 produces one second vibration frequency, and the 3rd frame layer 26 produces one the 3rd vibration frequency.
What especially will illustrate is, the material formation of the first frame layer 24 and the second frame layer 25 and the 3rd frame layer 26 is selected from as PBT, PA66, PPE, PA, the plastic cement material that PC, ABS, PPS are wherein arbitrary, the wherein material of the first frame layer 24 and the material difference of this second frame layer 25, first vibration frequency of this first frame layer 24 is different from the vibration frequency of this second frame layer 25, and the material of the 3rd frame layer 26 is different from this second frame layer 25, and the 3rd vibration frequency is different from this second vibration frequency.Material and this first frame layer 24 of the 3rd frame layer 26 are identical or different, the 3rd vibration frequency and this first vibration frequency identical or different.
Such as implement the first frame layer 24 one and be chosen as PA66 material, the second 25, frame layer is for selecting PBT material, and the 3rd frame layer is adopted as PPE material; Or implement this first frame layer 24 for PA66 material at another, the second frame layer 25 is PBT material, and the 3rd frame layer is PA66 material; These two kinds all can reach by the plurality of different plastic cement material and composition and the fan frame 20 that formed of the frame layer of different vibration frequency, resonate and noise situation with the fan frame 20 reduced in the running of this impeller 11.If the first frame layer 24 and the second frame layer 25 are PA66, the 3rd frame layer 26 is PBT; Or first frame layer 24 be PA66, the second frame layer 25 and the 3rd frame layer 26 are PBT, are all considered as two different frame layers.
In sum, the invention provides a kind of fan frame using two or more plastic cement material layer to be stacked to constitute, the vibration frequency by frame layer shape and material or material composition is different, and the excited frequency that staggers and free frequency, reduce resonance and noise situation.
Although the present invention discloses as above with mode of execution; so itself and be not used to limit the present invention, any person skilled in the art person, without departing from the spirit and scope of the present invention; when being used for a variety of modifications and variations, therefore protection scope of the present invention is when being decided to be standard with claims.
