Description
The present invention relates to a kind of dynamic power machine.
It is by a kind of novel energy conversion mechanism and dynamical element with geometry in particular thereof, the external work done of mechanically deformation that utilizes some material temperature difference shape memory effect to produce.With most representative shape-memory material-niti-shaped memorial alloy is example, and it is very soft when low temperature, and being subjected to very little external force effect is deformable; It is very hard when high temperature, and can promptly recover original shape memory.In this hot and cold cyclic process, the energy transfer mechanism that is complementary with it is running continuously again and again just, outputting power or drive generator for electricity generation.The present invention is exactly the dynamic power machine of making according to above-mentioned principle.
Since 1973 the U.S. " Ban Kesi " (Banks) develop " Ban Kesi motor " since, the countries in the world scientist has proposed various hot machine schemes, its structure and principle are similar, be about to " U " shape nitinol alloy wire and periodically successively immerse in the hot and cold tank, and make its to-and-fro motion that in water, produces convert rotatablely moving of output shaft to because of distortion.It demonstrates vitality, but inefficiency, is no more than 4% to 6%(usually and sees the 101st page to the 103rd page of " special metal " book that metallurgical industry publishing house publishes).In addition, or poor because of complex structure, sealing effect, and or, reason such as work discontinuous long because of exchange cycle influenced this new technology practicability that has a extensive future.
The objective of the invention is in order to overcome above-mentioned deficiency, provide a kind of can directly the generation to rotatablely move to improve the heat energy machine scheme of its thermal efficiency.
Above-mentioned purpose of the present invention solves by the following technical programs:
Mainly be by shape memory alloy component, the hot fluid case, the cold fluid case, the heat energy machine that axle is formed, its special way be the axle form by driving shaft (3) and driven shaft (9), and place hot fluid case (7) and cold fluid case (8) respectively, and in the part immersion fluid separately, the shape memory of shape memory alloy component (1) adopts bandlet closed circular ring-type, in it, after exchanging, the outer surface upset is sleeved on driving shaft (3) and the driven shaft (9), and, on shape memory alloy component (1), also be respectively arranged with the cold fluid sealing and wipe (2) and hot fluid sealing wiping (5) by back shaft (6) support that is positioned between driving shaft (3) and the driven shaft (9).
The driven shaft that more than contracts (9) can adopt little driven shaft (9 ') or big driven shaft (9 "); when adopting little driven shaft (9 '); shape memory alloy component (1) is mounted thereon by pine; and at driving shaft (3) and the formed cornerite of shape memory alloy component (1) corresponding part position-limited shaft (4) is set; when the big driven shaft of employing (during 9 "), its diameter should be equal to or greater than the diameter of driving shaft (3), shape memory alloy component (1) tightly is mounted thereon, and can or cancel position-limited shaft (4).
More than said main shaft (3) can make or thermal conductive material layer is set by Heat Conduction Material at its outer surface.
More than said position-limited shaft (4) can form by the single shaft more than three or three, also can adopt combination bearing.
More than the internal surface of said hot fluid case (7) and cold fluid case (8) be lined with insulation material layer, the fluid that is loaded in it can be liquid or gas.
More than each of said heat energy machine can horizontal arrangement or vertical arrange.
More than said shape memory alloy component (1) can be that monomer is formed or combined or be composited by the packing material (10) of shape memory alloy material and its core by some braidings, also can adopt the shape composition of earlier compound back braiding.
More than the internal surface of said shape memory alloy component can be lined with chain structure, driving shaft (3) and driven shaft (9) adopt gear structure, are chain-driven between them.Its cross-sectional configuration is the bandlet shape, and the setting shape memory is a closed circular, and the structural type that installation is used is that inside and outside circular surfaces upset is exchanged.
The working principle of technique scheme provided by the invention is: its critical component is shape memory alloy component (1), the shape memory that adopts is a bandlet closed circular ring-type, be contained on driving shaft (3) and the driven shaft (9) after the upset of its inner and outer surface exchanged, and by back shaft (6) support that is positioned between driving shaft (3) and the driven shaft (9), diaxon (3), (9) place respectively in hot fluid case (7) and cold fluid case (8) and the part immersion fluid separately.Shape memory alloy material is softer when low temperature, and is quite yielding; When it is in the high temperature phase time, hardening immediately produces the trend of recovering former shape memory and bigger power.Scheme of the present invention be exactly for fully, effectively utilize the moment that this restoring force produces and force driving shaft (3) rotation, thereby externally directly work done of output torque.Its concrete working procedure is such: when the shape memory alloy component (1) on being sleeved on driving shaft (3) is partly immersed in the hot fluid in the hot fluid case (7), its hardening immediately and recover the original former annular shape of remembering, but owing to be subjected to the effect of contraction of driving shaft (3), back shaft (6), driven shaft (9) and position-limited shaft (4), shape memory alloy component (1) just makes driving shaft (3) produce running torque and rotates.Shape memory alloy component (1) is crossed back shaft (6) after coming out from hot fluid case (7), just enters in the cold fluid in the cold fluid case (8), then beginning deliquescing and distortion, so that reenter work done once more in the hot fluid case (7).In this working procedure, hot fluid sealing wiping (2) and cold two fluid-tight wipings (5) are sealed the fluid of shape memory alloy component (1) adhering on surface band or wiping, mix to reduce, and keep the temperature difference, proceed work.
The present invention has the following advantages:
1. the saving energy.It is an operating conditions with the valuation and the low energy used heat of wide material sources hardly, and need not the necessary fuel of machinery powered by conventional energy.
2. do not pollute.It does not burn at work, does not have discharging, and is especially meaningful to avoiding the atmosphere greenhouse effect.
3. applied widely.It is not only applicable to chemical plant, power station, the nuclear power station that low energy used heat is concentrated, also be applicable to the utilization to the less solar energy of energy density, geothermal water, sea surface water,, there is the particular surroundings of the temperature difference, no oxygen or anoxic gas also can be used under the ore deposit, space etc.
4. simple in structure, easy to maintenance.
5. big, life-span of strength is long, renewable.The shape memory alloy component that it adopts (1), with the nitinol is example, make its transformation temperature difference of carrying out the phase transformation work done only need tens degree, even the several years, and its recovery elastic force maximum can reach 8.5 tons every square centimeter, and fatigue, creep or bending phenomenon (seeing that metallurgical industry publishing house publishes the 100th page, the 91st page of " special metal " book) can not appear in the general work hundreds of thousands yet.In addition, after its work some time causes performance depletion, also can heat-treat again-regeneration.
6. high working efficiency.NiTi motors such as " Ban Kesi ", it can directly be transformed into heat energy and rotatablely moves and do not need through this medium tache of to-and-fro motion, has reduced mechanical loss.In addition, shape memory alloy component (1) is bandlet closed circular ring-type, and it is exchanged the back in the positive and negative upset and uses, and has the effect that increases power character.Structure shown in its cross section helps heat radiation and accelerates hot and cold circulation.
