Below in conjunction with accompanying drawing, embodiments of the present invention are elaborated.
Embodiment one:
Please refer to Fig. 1, first the fan in the embodiment of the present application comprises driving structure.
Specifically, in the embodiment of the present application, driving structure provides rotating power for fan.The active force that in driving structure, magnetic field produces winding plays very large impact to the rotating speed of blade structure 1.If active force is large, fan will be very fast rotationally so, otherwise if active force is little, fan will be slower rotationally so.So can realize by controlling driving structure the control of rotation speed of the fan.
In specific implementation process, driving structure can be direct current motor, DC Brushless Motor etc.Direct current in electronic equipment or Ac are after transforming circuit and/or rectification circuit, and under the control of control circuit, input driving structure, so that the driving blade structure 1 of driving structure rotates, thereby drives N sheet blade structure 1 to produce wind.Certainly, under the application, the ordinary person of technical field can select the type of driving structure and concrete circuit as required, and the application does not do concrete restriction.
Blade structure 1, is connected with driving structure.Driving structure drives blade structure 1 to rotate, and blade structure 1 and then generation wind, promote electronic equipment dissipating heat.
As shown in Figure 2 a and 2 b, blade structure 1 comprises retaining ring 11, and driving structure can drive retaining ring 11 to rotate, and then drives blade structure 1 to rotate.
Be example below taking driving structure as DC brushless motor, how drive retaining ring 11 rotations to be introduced to driving structure.The stator of driving structure, winding is fixed on electronic equipment.One end of bearing is rotatably connected with stator.The other end of bearing is fixed on retaining ring 11, to fix and to support retaining ring 11.The inner side of retaining ring 11 is provided with magnet, thereby forms magnetic field.When after DC brushless motor energising, in the closed-loop path of winding, can form electric current, and the inner side of retaining ring 11 there is magnetic field, according to physical principle, retaining ring 11 will rotate, and rotates centered by the axle center of bearing.So now retaining ring 11 and bearing are equivalent to the rotor of DC brushless motor.
In the embodiment of the present application, bearing can use iron to make, and also can use the metals such as aluminium to make.Bearing also can be made with stainless steel or pottery.Certainly, in order further to alleviate the weight of fan, also can make with nonmetallic lightweight material, as plastics etc.
Bearing can be the cylinder that a root radius is identical, also can form by the different cylinder of many parts radius, for example bearing two ends are respectively the cylinders of radius 0.25cm, and intermediate portion is the cylinder of radius 0.27cm, and the length of the cylinder of radius 0.25cm is 0.3cm, the length of intermediate portion is 0.5cm.Under the application, the ordinary person of technical field can arrange as required, and the application does not do concrete restriction.
Further, in the embodiment of the present application, blade structure 1 also comprises N sheet flabellum 12.N sheet flabellum 12 is arranged on retaining ring 11, and wherein, the set-up mode of N sheet flabellum 12 on retaining ring 11 is formed in one, and in other words, retaining ring 11 and N sheet flabellum 12 form via same Mold Making.
Further, in order to alleviate the weight of fan, in the embodiment of the present application, the thickness of the every flabellum 120 in N sheet fan is less than 0.35mm.Flabellum thickness of the prior art be grade other, be generally 6mm, so every flabellum 120 flabellum more of the prior art in the application's technological scheme is thinner, in the situation that flabellum density is identical, the weight of the fan in the embodiment of the present application fan more of the prior art is lighter so.
Due to 12 attenuation of N sheet flabellum, therefore, in order to promote the performance of the fan in the embodiment of the present application, the quantity N of N sheet flabellum 12 is greater than 35 and is less than or equal to 70, and N is integer.
When the quantity of flabellum has increased, blade structure 1 entirety promotes the performance of Air Flow, and namely heat dispersion is just improved.
Further, because the thickness of N sheet flabellum 12 is less than 0.35mm, so, in the knockout course after being shaped in mould, be easily damaged.Damaged for fear of blade structure 1, in the embodiment of the present application, blade structure 1 also comprises stripper rings 13.
Stripper rings 13 is arranged on N sheet flabellum 12, and as shown in Figure 2 a and 2 b, the first radius of stripper rings 13 is greater than the second radius of retaining ring 11.The first radius of for example stripper rings 13 is 3.9cm, and the second radius of retaining ring 11 is 1.7cm; Or the first radius of stripper rings 13 is 4cm, the second radius of retaining ring 11 is 1.7cm; Or the first radius of stripper rings 13 is 3.9cm, the second radius of retaining ring 11 is 2cm.Under the application, the ordinary person of technical field can arrange as required, and the application does not do concrete restriction.
Stripper rings 13 is arranged on N sheet flabellum 12, and in blade structure knockout course, the thrust upwards that thimble produces N sheet flabellum 12, just can conduct a part on stripper rings 13.In other words, stripper rings 13 can be shared the power of thimble for N sheet flabellum 12, and then makes blade structure 1 more be easy to the demoulding, and can protect N sheet flabellum, reduces the impaired possibility flabellum of blade structure.
If the first radius of stripper rings 13 equals the second radius of retaining ring 11; it is the butt that stripper rings 13 is just arranged on N sheet flabellum 12; the power that thimble applies N sheet flabellum in knockout course so, the power being transmitted in stripper rings 13 will be very limited, so 13 of stripper rings can not be protected N sheet flabellum.
And if the first radius of stripper rings 13 is less than the second radius of retaining ring 11, because the butt of N sheet flabellum 12 is fixed on retaining ring 11, stripper rings 13 now cannot be arranged on N sheet flabellum so.
Further, stripper rings 13 is formed in one at the set-up mode of N sheet flabellum 12, and in other words, stripper rings 13 and N sheet flabellum 12 form via same Mold Making.And in use, stripper rings 13 also can together be used fan in the embodiment of the present application.Under the application, the ordinary person of technical field can arrange as required, and the application does not do concrete restriction.
Optionally, in knockout course, for further protection blade structure 1, in the embodiment of the present application, the first thickness of the random site of every flabellum 120, is greater than the thickness of N sheet flabellum 12, as shown in the circle on every flabellum 120 in Fig. 3 a-Fig. 3 c.Specifically, the random site of every flabellum 120 is the arbitrary position between every flabellum 120 butts and top specifically, comprises butt and top.Random site in N sheet flabellum 12 can be all identical, as in Fig. 3 b all at apical position, or if Fig. 3 c is all in neutral position.Certainly, the random site of different flabellums also can be different, and as shown in Figure 3 a, or for example N sheet flabellum has 50, and wherein the random site of the 1st, 3,22,39 is on the top of corresponding flabellum, and the random site of all the other flabellums is in the centre of corresponding flabellum.Under the application, the ordinary person of technical field can arrange as required, and the application does not do concrete restriction.
Further, in working process, by the random site thickening of every flabellum 120, namely pass into more making material at random site, make the first thickness of every flabellum 120 random sites be greater than the thickness of N sheet flabellum 12.The for example thickness of N sheet flabellum 12 is 0.20mm, and the first thickness can be 0.40mm so; Or the thickness of N sheet flabellum 12 is 0.34mm, the first thickness can be 0.40mm so; Or the thickness of N sheet flabellum 12 is 0.15mm, the first thickness can be 0.32mm so.Under the application, the ordinary person of technical field can arrange as required, and the application does not do concrete restriction.
By at the random site of every flabellum 120, flabellum being thickeied, and then strengthen blade structure 1 repellence to external force in knockout course, thereby reduced the impaired possibility of blade structure 1.
Optionally, for the demoulding better, the cross section of N sheet flabellum 12 is specially an irregular polygon or irregular cycle.Specifically, because the thickness of the N sheet flabellum 12 in the embodiment of the present application is less than 0.35mm, therefore in knockout course, easily damage, therefore in knockout course, can adopt the odd-shaped cross section demoulding, the cross section of N sheet flabellum 12 is an irregular polygon or irregular cycle, please refer to five kinds of cross sectional representation in Fig. 4, but in specific implementation process, include but not limited to five kinds of shape of cross sections in Fig. 4.
Cross section by N sheet flabellum 12 is set to irregular polygon or irregular cycle, can protect N sheet flabellum, reduces the impaired possibility of blade structure.
Optionally, except the thickness of N sheet flabellum 12 is set to be less than 0.35mm, can also further make the blade structure 1 in the embodiment of the present application with high strength composite.In the embodiment of the present application, the making material of blade structure 1 can use LCP (polymeric liquid crystal copolymer, Liquid Crystal Polymer).
Specifically, LCP is a kind of model engineering plastic growing up at the initial stage eighties.Polymerization is taking melt polycondensation as main, and all aromatic LCP is aided with solid phase polycondensation to make high molecular weight products more.LCP tensile strength and flexural modulus can exceed the various thermoplastic engineering plastics that grow up over 10 years.Mechanical property, dimensional stability, optical property, electrical property, chemical proofing, flame retarding, processability are good, and heat resistance is good, and thermal expansion coefficient is lower.
The characteristic of LCP being carried out to one below simply introduces:
The first, polymeric liquid crystal copolymer resin is generally ecru, also has the opaque pressed powder being white in color, and density is 1.4～1.7g/cm3, so visible, the density of polymeric liquid crystal copolymer is very little.The second, liquid-crystalline polymer also has good thermostability, heat resistance and chemical proofing, the creep shortcoming that most of plastics are existed, and liquid crystal material can be ignored, and wear-resisting, all excellences of anti-attrition.The 3rd, weathering resistance, the radiation resistance of LCP are good, have excellent flame retarding, can knock down the flame and no longer proceed burning.Its burning grade reaches UL94V-0 level level.LCP is one of best special plastic of fire savety.The 4th, LCP has good electrical insulation capability.Its dielectric strength is higher than common engineering plastics, and arc resistance is good.As appliance applications product, while having 200～300 DEG C of continuous serviceability temperatures, its electrical property is unaffected.Can reach 316 DEG C of left and right and be interrupted serviceability temperature.The 5th, LCP has outstanding decay resistance, and the alkali that the acid that LCP goods are 90% in concentration and concentration are 50% can not suffer erosion under existing, for industrial solvent, fuel oil, washing agent and hot water, can be not dissolved after contact, and can not cause stress cracking yet.
In addition, except polymeric liquid crystal copolymer LCP, the blade structure 1 in the embodiment of the present application can also use the composition of polyphenylene sulfide and glass fibre.Polyphenylene sulfide, English: Polyphenylene sulfide, is called for short PPS.The composition of PPS and glass fibre also can be used as the making material of blade structure 1.
To simply introduce PPS below:
Polyphenylene sulfide full name is polyphenylene thioether, is the thermoplastic resin with thiophenyl in molecular backbone, and polyphenylene sulfide is a kind of crystalline polymer.Unstretched fiber has larger amorphous region (degree of crystallinity is about 5%), and crystallization heat release occurs in the time of 125 DEG C, and vitrification point is 150 DEG C; 281 DEG C of fusing points.Stretched fiber has produced partially crystallizable in drawing process, and (being increased to 30%), as stretched fiber heat-treated at 130-230 DEG C of temperature, can make degree of crystallinity be increased to 60-80%.Therefore, the fiber after stretching does not have obvious glass transition or crystallization exothermic phenomenon, and its fusing point is 284 DEG C.Along with the raising of stretching heat setting post crystallization degree, the density of fiber is corresponding increase also, by stretch before 1.33g/cm3 to stretching after 1.34g/cm3, after heat treatment can reach 1.38g/cm3.
PPS is a kind of special engineering plastics of excellent combination property.PPS has good high temperature resistant, corrosion-resistant, radiation hardness, fire-retardant, balanced physical and mechanical properties and the fabulous feature such as dimensional stability and good electrical property, be widely used as structural macromolecular material, by being widely used as special engineering plastics after filling, modification.Meanwhile, also can be made into various functional films, coating and composite material, application succeeds in fields such as electronic apparatus, Aero-Space, Automobile Transportations.PPS is sulfur-containing aromatic polymers, and line style PPS is at 350 DEG C of above crosslinked rear one-tenth thermosetting plasticses, and branched chain type structure PPS is thermoplastic.PPS is that first U.S.'s Karen Phillips realized industrialized production in 1971.
Except above-mentioned LCP, and outside PPS and glass fiber compound, the making material of the blade structure 1 in the embodiment of the present application can also use the composition of polyether-ether-ketone and glass fibre.
Polyether-ether-ketone, English: poly ether ether ketone, is called for short: PEEK.PEEK contains the high polymer that the repetitive of a ketonic bond and two ehter bonds forms in backbone structure.
Below PEEK is simply introduced.
334 DEG C of PEEK fusing points, 168 DEG C of softening points, tensile strength 132～148MPa, can be used as high-temperature-resistant structure material and electrically insulating material, can with glass fibre or the compound reinforcing material of preparing of carbon fiber.Generally adopt with the condensation of aromatic dicarboxylic phenol and the class polyarylether class high polymer obtaining.
Polyether-ether-ketone PEEK has higher glass transition temperature (Tg=143 DEG C) and fusing point (Tm=334 DEG C), and its load heat distortion temperature is up to 316 DEG C, and long-term serviceability temperature is 260 DEG C, and instantaneous serviceability temperature can reach 300 DEG C.Mechanical property polyether-ether-ketone PEEK has rigidity and flexibility, particularly very outstanding to the fatigue resistance under alternating stress, can compare favourably with alloy material.Polyether-ether-ketone PEEK has good sliding properties, is suitable for being strict with the occasion of low coefficient of friction and abrasion performance purposes, particularly uses the PEEK wear resistance of the slip trade mark of carbon fiber, graphite, PTFE modification very superior.Except the concentrated sulphuric scid, PEEK is insoluble to any solvent and strong acid, highly basic, and hydrolysis resistance, has very high chemical stability.Polyether-ether-ketone PEEK has self-extinguish ability, even if do not add any fire retardant, can reach the 94V-0 level of UL standard.Due to PEEK, to have temperature flowing good, and the very high feature of heat decomposition temperature can adopt multiple processing mode: injection moulding, extruding and moulding, compression molding and melt spinning etc.
From above-mentioned brief introduction, can find out, all there is the features such as density is low, high strength due to polymeric liquid crystal copolymer, polyphenylene sulfide and polyether-ether-ketone, therefore, no matter the blade structure 1 in the embodiment of the present application adopts the composition of polymeric liquid crystal copolymer, polyphenylene sulfide and glass fibre or the composition of polyether-ether-ketone and glass fibre to make, can alleviate the weight of fan, thereby realize the weight that alleviates electronic equipment entirety.
Further, in the embodiment of the present application, N sheet flabellum 12 can adopt short blade mode.If adopt short blade mode, the length of every flabellum 120 is less than the first radius, and namely the length of every flabellum 120 is less than or equal to the first radius of stripper rings 13.
Please refer to Fig. 2 b, because the radius of every flabellum 12 is less than the first radius, so stripper rings 13 is arranged on the top of N sheet flabellum 12, N sheet flabellum 12 does not exceed stripper rings 13.Bright for instance, the first radius of supposing stripper rings 13 is 4cm, and so the length of every flabellum 120 can be 3cm; Or hypothesis stripper rings 13 the first radius be 4cm, so the length of every flabellum 120 can be 2.5cm; Or hypothesis stripper rings 13 the first radius be 3.8cm, so the length of every flabellum 120 can be 3cm.More example will not enumerate here.Under the application, the ordinary person of technical field can arrange as required, and the application does not do concrete restriction.
In addition, in the embodiment of the present application, N sheet flabellum 12 can adopt air-foil blade mode.Please refer to Fig. 2 a, N sheet flabellum 12 with the tangent plane of retaining ring 11 set-points at angle, as 30 °, 45 °, 60 ° etc., do not limit for concrete angle the application.The set-up mode of air-foil blade, determining of angle and each parameter etc. is set to of the prior art similar, just repeated no longer one by one here.
Optionally, for the N sheet flabellum 12 in the embodiment of the present application is securely fixed on retaining ring 11, in the embodiment of the present application, the 3rd thickness of every flabellum 120 butts is different from the 4th thickness on top.Bright specifically, suppose that the 3rd thickness of every flabellum 120 butts is 0.25mm, the 4th thickness on top is 0.15mm; Or the 3rd thickness of every flabellum 120 butts is 0.15mm, the 4th thickness on top is 0.25mm, as long as the 3rd thickness of every flabellum 120 butts is different with the 4th thickness on top, for the concrete value of the 3rd thickness and the 4th thickness, the application does not do concrete restriction.
In specific implementation process, the 4th thickness that the 3rd thickness of every flabellum 120 butts is greater than top is better selection, and the center of gravity of every flabellum 120 is more near butt like this, so in rotation process, or in knockout course,, be difficult for coming off or separating from retaining ring 11 near top compared with center of gravity.
Optionally, comprise that on the surface of N sheet flabellum 12 K enters glue point and leaves over a little.
Specifically, in working process, the space in mould is the space of an approximate sealing, the making material of the blade structure 1 in the embodiment of the present application, by mould multiple enter in space in glue point inflow mould.Therefore,, after blade structure 1 moulding, can stay into glue point and leave over a little on the surface of N sheet flabellum 12.
Further, in the embodiment of the present application, because the quantity of N sheet flabellum 12 is for being greater than 35, be less than or equal to 70, so flabellum more of the prior art is more, so, if make on the mould of blade structure 1 of the embodiment of the present application to enter glue point less, may cause so making material and be not yet full of whole die space time, just solidified.So, solidify in advance for fear of making material, N sheet flabellum 12 lip-deep enter glue point leave over quantity a little and be greater than 3 and be less than or equal to 15, i.e. 3 < K≤15, K is positive integer.
