Description

Liquid nitrogen cold drive power

Technical field that the present invention belongs to is:

1. 3. coal and oil power generation industries fields, 2. engine power fields, vehicle manufacturing industry field

Illustrating: before reading this paper, advise that you please read the annex of this paper earlier---keyword is explained.

Background technology of the present invention:

As everyone knows, in power generation industries field, manufacturing field and other each side of various automobiles now, the human energy source that can utilize mainly is an oil, natural fuels, coal, hydrogen, biogas, water conservancy, wind-force and nuclear energy and the following resources of using such as tritium, especially modern various automobiles or various means of delivery and some electrical generator almost obtain energy by burning entirely and solve driving problems.The application of this theory has brought convenience and interests to us, has also brought huge problem (although revising the technical standard of some automobile very high in the world at present) to us simultaneously: environmental pollution, exhale pernicious gases, and emit surplus heat.Along with people use extensively and these sharp-pointed international difficult problems of the continuity of period of service put in face of common people.Their common ground roughly of the occupation mode of above-mentioned these energy is as follows:

Resource (sooner or later to use up. generally duplicate and the difficulty of regenerating. the deposit condition is restricted etc.);

2. send surplus heat; 3. discharge useless (poison) gas;

4. what use is serve as the main thought of acquisition propulsive effort with " heat drives " principle;

Thereby the creature who causes the present earth and all to live in this celestial body is faced with the threat (reason that also has other certainly) that living environment worsens.Be accompanied by the deterioration of life condition---green-house effect, meteorological change (increasing typhoon, heat wave, cross drought and cross waterlogging, is dissolving etc. at the two poles of the earth), excessive use of resource and capital market are comed one after another for the recurrent fluctuations of energy prices even the global problem that brings on a war or the like, and now worldwide " financial tsunami " is exactly illustration.

Generally speaking, the mankind are diversified in order to overcome gravitational energy source at present, each have their own merits and faults.Important problem all has direct relation with " heat drives ".Under this background technology, we should change at " heat drives ".Let us changes thinking: see from space our this celestial body is put it briefly and is made up of earth entity and the air that surrounds it, be equivalent to the moon (earth) in east and the simple philosophical theory of positive (air).It is refreshing will that this two big corresponding part is formed.Opposedly just can utilize, overcoming gravitational best approach is to utilize his another side---air.The carrier of the energy that air is collected as us is realized new propulsive effort.I think: to be a kind of " passive " in fact with the energy that contains in the air compile the mode of the natural wind energy of human use (flow air) generating receives and the process of trans-utilization, sends how many electric energy and will see the wish in Heaven and decide.The present invention is that " actv. " utilizes air wind energy in other words, according to our needs and use amount, arbitrarily quantitatively sends energy at any time and also effectively and reasonably uses.I propose liquid nitrogen cold and drive the theory and technology viewpoint at " heat drives " theory and technology, be called for short cold driving principle technology, (as long as technical permission with liquid air also can) come actv. to overcome various " international " defective that " heat drive " is brought in this way, with good conditionsi in other words substituting " heat drives ", will actv. reduce the discharging of useless (poison) gas and waste heat, also saved simultaneously resource, and then make the mankind more progressive for the technical approach that the propulsive effort that obtains the external world uses, harmonious more with the Nature.

The invention detailed content:

The one .. " heat drives " to be solved by this invention technical matters:

" heat drives " is to obtain propulsive effort by some resource of burning as its name suggests.No matter how advanced the technical thought of its use and mode have, " heat " can 100% yet be utilized, always have the loss of part, distribute towards periphery, directly cause " heat " to pollute, simultaneously, this mode also produces various objectionable impuritiess, these situations are well-known, and the resource of being burnt (as: gasoline. diesel oil. coal or the like) also the moment " heat drives " the anxiety variation of capital market; When in sum, the mankind have arrived this change acquisition propulsive effort mode.And the cold type of drive that the present invention uses does not have the notion of " heat ", opposite with " heat drives " fully, be that the contained energy of nitrogen (or air) after the liquefaction is carried out trans-utilization by some mode, and then generation propulsive effort, do not have any " international pollution " and the resource problem in " heat drives " mode, also have the effect of certain environment purification concurrently, it is clean nitrogen to external world's discharging that the technological process that purifies air and acting back must be arranged when for example producing liquid nitrogen.If present technique is applied universal, will give cooling earth, all many-sides such as use that reduce resource obtain substantial progress.

The 2nd, the present invention will solve the technical scheme that " heat drives " technical matters adopts

Cold actuation techniques principle center with respect to " heat drives " is exactly " liquid nitrogen "! If technical possible " liquid air " is good; Air is ubiquitous, and duty gas more than 72% is nitrogen, and nitrogen has stable physics and chemical property, and not spontaneous combustion is not combustion-supporting yet.To generally speaking, purity is 99.5%, and the nitrogen of dew point-60 ℃ very easily obtains, and importantly now large-scale production technology is ripe, and suitability for industrialized production adapts to fully, does not have resource problem, only requires appropriate measures in the use.Can realize the liquid nitrogen of directly annotating when vehicle-mounted liquid nitrogen replenishes, just as present petrol service station refuels, its practicality is possible.Concrete technical scheme is (automobile being classified as for example for ease of narrating me):

One. " cold driving " power resources---the design of liquid nitrogen pneumatic power system:

" storage of liquid nitrogen gas nitrogen and the fit storehouse of decompression ":

The nitrogen (getting final product of low-purity) of liquefaction is stored in the transportation storage dual-purpose type liquid nitrogen container of particular design, it is seated in " liquid gaseous state conversion decompression storehouse ", be actually in " liquid gaseous state conversion decompression storehouse " one " transportation stores liquid nitrogen container " arranged again, be considered as original nitrogen, also have a decompression storehouse in other words in the outside of " transportation stores liquid nitrogen container "; Two container sets together but can regard two separate components as.Liquid nitrogen is directly released in " liquid gaseous state conversion decompression storehouse " by " Tai Ji door " and pipeline, and " liquid gaseous state conversion decompression storehouse " becomes gas nitrogen attitude with post-decompression liquid nitrogen, by corresponding pipeline and equipment, becomes the power gas that is provided.This and two and a design-calculated meaning is: 1. as to reduce equipment occupation space, otherwise must design promptly one in two jars " transportation stores liquid nitrogen container ". one " liquid gaseous state conversion decompression storehouse " 2. " liquid gaseous state conversion decompression storehouse " has the certain protection effect to " transportation stores liquid nitrogen container ", have certain working pressure such as " decompression storehouse, liquid gaseous state conversion storehouse ", the safety that objectively more helps original liquid nitrogen container (has reduced the direct contact with the external world, as temperature. from exterior direct impact etc.), original liquid nitrogen container is if there be collecting on the spot in the decompression storehouse that the gas leakage of trace can be covert to be used; 3. on the problem of transportation, added safety control to it again with the storage liquid nitrogen; The quality requirements of these two jars requires: can be shockproof. and heat insulation. withstand voltage coefficient height. be convenient to maintain and replace. can resist and dislike slightly road conditions and weather (+60 degree--40 degree can be worked), capacity is big as much as possible.To satisfy certain operating needs.On fit jar, design simultaneously as lower device:

1.a being furnished with safety-valve (function slightly) b nitrogen leakage warning device c is convenient to from the supply mouth and the pipeline of outside filling liquid nitrogen;

2. jar outer design be convenient to installing/dismounting replace have stable. the shockproof function parts, also should consider actv. lightning protection electric installation simultaneously;

3. be equipped with and send the by-pass valve control of stopping the supple of gas or steam by the special type of the anti-unlatching of automatic computer automatically controlled, be connected to＜transport the storage liquid nitrogen container〉and＜liquid gaseous state conversion decompression storehouse〉on, { this valve called after: " Tai Ji door " is in the middle of liquid nitrogen and the gaseous nitrogen because of it };＜Tai Ji door〉port opens into＜liquid gaseous state conversion decompression storehouse〉liquid nitrogen is discharged into＜liquid gaseous state conversion decompression storehouse in, the another port is connecting each bar pipeline of refrigeration, be the system of the need refrigeration original liquid nitrogen that provides support, the required liquid nitrogen of the refrigeration of each system by centralized computer through Digital Control by＜Tai Ji door finish; Consider＜Tai Ji door from simplified design〉also should possess from the external world and replenish " liquid nitrogen " passage promptly: " liquid nitrogen replenish mouthful ";

Two. cold driving power resources---nitrogen power gas supply system principle of work:

Extraneous through " liquid nitrogen replenish mouthful " finish to original＜transportation with pipeline and store liquid nitrogen container〉replenish liquid nitrogen overall process (summary); Required major part title and function:

1. in " liquid gaseous state conversion decompression storehouse ", original liquid nitrogen is finished the conversion of gaseous state and is formed certain supply gas pressure in this storehouse, sufficient power gas is provided at any time;

2. original liquid nitrogen is delivered directly to a/c system, because the pressure in " liquid gaseous state conversion decompression storehouse " is lower than the pressure of original nitrogen pot, liquid nitrogen behind the refrigeration work is transformed into gaseous nitrogen to be got back in the decompression storehouse through air-conditioning duct, original liquid nitrogen. air-conditioning. " liquid gaseous state conversion decompression storehouse " three constitutes the loop of a circulation path, and the nitrogen after the refrigeration is used for replenishing prime power.Then should consider it to be drawn in " breathing " storehouse in this loop if insufficient pressure can not be got back to " liquid gaseous state decompression storehouse ", transform supply gas (compressor assembly sees below) into for " secondary nitrogen " by compressor assembly;

3. original liquid nitrogen imports directly that " secondary nitrogen " is utilized in the refrigerating channel of compressor " breathing " gas tank of system, be used for refrigeration to the nitrogen secondary compression system that loops back, to improve compression effectiveness, also reduced simultaneously the discharging (heat-producing during the secondary nitrogen compression) of " heat " to greatest extent, original liquid nitrogen. " breathing " storehouse of " " secondary " nitrogen recycling compressor ". liquid gaseous state decompression storehouse three also constitutes a circulation path, nitrogen after the refrigeration acting is got back in " liquid gaseous state conversion decompression storehouse ", is used for replenishing prime power.Can not get back to " liquid gaseous state conversion decompression storehouse " as if pressure also deficiency and then consider heavily it to be drawn in " breathing " storehouse, transform supply gas into into " secondary " nitrogen by compressor assembly;

Suggestion: will finish each the loop nitrogen behind the refrigeration work during design, the passage by certain is pooled in " breathings " storehouse of " secondary nitrogen " recovery system and is primary selection.

Explain: the function and the effect of " Tai Ji door ":

Function valve for liquid nitrogen and gaseous nitrogen realization conversion, be 1. original＜liquid nitrogens transportation storage tanks〉2.

B. " liquid gaseous state conversion decompression storehouse " system:

Function: liquid nitrogen not directly is used for doing drive force source; also be the needs that cut the waste; therefore; equip " liquid gaseous state conversion decompression storehouse " original liquid nitrogen used preceding liquid---the gaseous state buffering; to discharge the original liquid nitrogen of coming by " Tai Ji door " and be transformed into gaseous nitrogen atmosphere; and keep certain supply gas pressure, simultaneously, the meaning that " original liquid nitrogen transportation storage tank " protected is arranged also.

The major part title:

1. " liquid gaseous state conversion decompression storehouse " warehouse 2. safe sensory perceptual system such as compression indicators. reducing valve, lightning protection equipment etc.

3. the fixing and shock mitigation system 4. that is installed in car body outside the storehouse connects the path of " nitrogen four seasons valve "

5. the nitrogen loop after fixing " Tai Ji door " and being connected a/c system and compressor " breathing " storehouse refrigeration, (nitrogen after the refrigeration does not have enough pressure can get back under the situation in this storehouse, then arranges to be reclaimed by " secondary nitrogen " compressor air suction jar)

" liquid gaseous state conversion decompression storehouse " designing requirement:

" 1.a liquid gaseous state conversion decompression storehouse " device pressure perception table. critical valve and row pressure pipeline; The b outside has the fixed system with the shockproof damping of car body bonded assembly; C should consider to design the lightning protection lightning protection;

2. sturdy and durable. possess certain collision ability of bearing, for alleviating car body weight, it is available makes such as chemical materials such as carbon fibers, its capacity and depend on the needs with the ratio of " original liquid nitrogen transportation storage tank ";

3. " Tai Ji door " monitors the work of adjusting original liquid nitrogen container and liquid cyclostrophic storehouse constantly, also take into account the supply of refrigerant, its sensitivity level is directly connected to the work efficiency and the safety of whole systems, this technical requirements must be very high, therefore advocate by computer and carry out digitalisation sequencing control, to improve performance accuracy and fiduciary level by its each function;

Three. the power operated reception working system of nitrogen:

1. " nitrogen four seasons valve ": be made up of four nozzle block, positive and negative two nozzles of every configuration set are separately fixed in four nozzle boxs of cylinder.Its upstream is: 1). connecting " liquid gaseous state conversion decompression storehouse " through path and the power nitrogen that comes by positive nozzle;

2. auxiliary jet is then connecting the " secondary nitrogen " path that " exhaling " gas tank of " " secondary " nitrogen recycling compressor " system is sent here through path; Positive and negative nozzle is all awarded the acting of supplying gas of gas blade to the rotor in its downstream " cold driving annual ring ", and its mode of operation whole process is controlled by centralized computer; Every group respectively with the spring. the summer. and the autumn. the winter name.Technical requirements to " nitrogen four seasons valve ":

A. " nitrogen four seasons valve " will be fixed on " cold driving annual ring ", also wants removable detachable convenient for maintaining.The fixed position will lock four of scope of the circumference 360 deg all points, promptly every group (just. negative) the valve relative position is just at 90 degree; If with first valving called after " spring " of lower left of annual ring, then upper left second valving is " summer ", by that analogy, can suitably successively decrease or progressively increase since spring supply gas pressure successively.Auxiliary jet (" secondary nitrogen " is provided) can.Auxiliary jet helps the at the uniform velocity running of rotor, keeps the formula of the cruising running of rotor;

B. " nitrogen four seasons valve " nozzle wants durable low temperature resistant, lowers the noise when penetrating high velocity air as far as possible, can strengthen its bore; Before being fixed in " cold driving annual ring " nozzle chamber, should calculate optimal incident angle in fact,, reduce unnecessary consumption to reach best driving effect according to the situation of rotor.

* about the recovery reason of " secondary nitrogen ":

By convention, if the liquid nitrogen deposit can enough be provided by the needs that provide of (certain stroke limit) power capacity, just can save the step that reclaims nitrogen, nitrogen after the acting is directly arranged in atmosphere, or be that compression power is directly compressed outside air and then assisted the power (if necessary) that provides auxiliary, its reason with the storage battery:

1) because of consider saving original liquid nitrogen, prolongs the service life of liquid nitrogen as much as possible, the storage level of original liquid nitrogen that this has equaled covert increasing;

2) " " drive the rotor acting after the recovery again, the conversion of its energy realizes by " cold driving annual ring " secondary nitrogen, and " cold driving annual ring " is the labour-saving instrument;

3) " secondary nitrogen " is that low temperature is cold, and compression is that electricity consumption is less relatively;

2. " cold driving annual ring ":

" cold driving annual ring " be directly bear from the high speed nitrogen of " nitrogen four seasons valve " stream drive and simultaneously directly the kinetic energy that nitrogen is contained become mechanical energy and be transferred to central module on the generator amature, it is the core component of " cold driving ", be steam turbine. combustion engine " rotor. piston " and the distortion or the mutation of " cylinder " that be complementary with it combination, the important task of forming a connecting link born.

Design and technical requirements to " cold driving annual ring " each parts:

A. contained principle: " lever principle ": power * power arm=resistance * resistance arm (set forth and omit)

Therefore, the diameter that adds large annual rings to greatest extent will be to obtain the decision condition that maximum is made " merit " labor-saving effect, be related to saving " original " source nitrogen, the requirement that as far as possible prolongs the electrical generator work timing; The rotor that also will take into account electrical generator simultaneously traveling at the uniform speed under certain condition; Mode of operation and outward appearance have multiple, mainly contain " edge gear transmission " and types such as " center crankshaft drive " and wind energy type transmission;

This description is limited to vapour (sedan-chair) car, and therefore (from appearance) decides the Φ into 1000mm/ with it, and maximum ga(u)ge is 60mm, and the center is UFO-like with moving axis type outward appearance; Edge gear molded breadth degree is 900mm, and other parts can be arranged to place in the space at center; The concrete data size standard of various " cold driving annual ring " should be looked concrete environment for use and be taken the circumstances into consideration to determine;

B. " cold driving annual ring " each component names and function thereof:

Parts are formed: control brake gear in cylinder (in the cylinder and outside the cylinder) the cylinder bearing part rotor cylinder

The same moving axis of the blade of rotor

Each component function:

Cylinder is the shell of " cold driving annual ring ", with oblateness is its body shape, the material of selecting for use should be sturdy and durable, and water-fast or aqueous vapor corrosion, non-corrosive, weight is lighter again, and its effect is that the high velocity air of nitrogen and rotor portion and ambient atmosphere are separated, form type and closed type operation chamber (just as combustion chamber), guarantee that nitrogen stream is at " cold driving annual ring " the inner switching process of finishing energy by the rotation of rotor;

● in the cylinder: four nozzle boxs are installed, and air nozzle is certain angle, and each spout is crosswise to be arranged, but all be equidirectional towards, angle is too; And reserve two exhausr ports, be the corresponding shape of 180 degree; The ball orbit band of two circles for stable and support rotor arranged, and the flywheel of its shape and structure and bicycle is similar, forms a bigger bearing body jointly with rotor; And be reserved with for the position that the rotor emergency brake arrangement is installed (if this think unnecessary omits);

● outside the cylinder: it is admission port that four " nitrogen four seasons valve " are connected corresponding with the nozzle box of nozzle body are arranged; Two exhausr ports are respectively connecting " secondary nitrogen " recovery system " suction " feed channel; Another function of exhausr port is exactly when recovery system is not worked for some reason, under the control of computer (manually all can) automatically with Exhaust Open the row of the excess power gas in the cylinder to atmosphere, otherwise it will be in the SELF CL state to keep the above-mentioned operation scheme in the cylinder;

C. cylinder bearing part

The cylinder bearing is an important component part of " cold driving annual ring "; Be used for whole gravity of bear rotor, the resistance when reducing rotor rotation is determined the tram of rotor in cylinder; The measure of precision of bearing and quality directly have influence on the acting quality of rotor, no matter " cold driving annual ring " is vertically to place or keep flat the work that (electrical generator is last or following) all can not influence rotor vertically, therefore, its relative hardness. durability. the standard of lubricity is very high;

D. rotor:

Rotor is installed in " cold driving annual ring " cylinder and is circular, maximum width 30-35mm (optionally decide, thickness also in like manner) accepts the high speed nitrogen stream that " nitrogen four seasons valve " nozzle penetrates by the air blade of awarding of rotor, the kinetic energy of nitrogen is converted to mechanical energy, make the rotor rotation.

Rotor can be designed to " center crankshaft drive " type, " edge gear transmission " type also, or be " wind energy type transmission " type (suggestion is with reference to the wind-driven generator principle);

Technical requirements to rotor:

Rotor is processed by alloy steel forging integral body.This rotor since do not bear " heat " can, preferably select light weight. robust material, and by fine limit work, (fit on all award air blade after), carry out full speed and rotate test and accurate kinetic balance; Also can and award air blade and directly be cast as one rotor itself, be that the Blade Design that rotor is awarded wind-force face one side becomes oblique wave and every crest top by one whole connection of abutment wall, form the force of awarding one by one, also can be with reference to " vertical axis wind energy electrical generator " is awarded the fan rotor principle design.

" center crankshaft drive " type three points of top end part in the 360 degree circles of the inboard of rotor, " spoke " that connects the rotor of centre dot (during casting and rotor become one) is respectively arranged, prevent again rotor in rotation " jump. dragon " phenomenon, also propulsive effort is transferred to on the moving axis by the center point of connection simultaneously.(other blade of its weight ratio is heavy slightly near can considering these 3 rotor blades);

Rotor inner ring of " edge gear transmission " type or outer ring are left the gear tooth and are meshed with moving tooth axle, are connected with the rotor of electrical generator by the tooth axle; " wind energy type driving type " (summary).

The rotating speed of rotor should pass to the center host computer by certain induction channel, for the work of adjusting electrical generator constantly.

Extra prompting:

If necessary, the not wind-engaging back side of various rotor then can be designed to not bear nitrogen power wind and have the slowing-down brake functional device, and is combined with the brake part of reserving in the cylinder, forms brake function, in order to emergency.

E. same moving axis:

Be to accept the parts that power that rotor hands down drives the electrical generator rotation.

* the same moving axis of " center crankshaft drive " type is knotted the point of connection of " cold driving annual ring " rotor inboard three " spokes " at the first line of a couplet, and at the rotor that is connecting electrical generator down, its position is at the center of " cold driving annual ring ", by its rotation of bearings;

* the rotor institute bonded assembly of " edge gear transmission " type, is transmitted to power on the generator amature through being meshed with the teeth of rotor with moving tooth axle, but these kind of epitrochanterian teeth and rotor block cast solid, to reduce the link of transmission.Teeth can also can be in the outside of rotor in the inboard of rotor.

Technical requirements with moving axis:

1. no matter be that " " type or its same moving axis that is disposed of " edge gear transmission " type shorten the transmission distance with the downstream electrical generator to the same moving axis in center as far as possible; Be optimal combination, if situation allows, also can cancel with the moving axis type of drive, promptly be interpreted as: adopt the epitrochanterian mode that rotor is directly connected to electrical generator to drive, will drive a part of nitrogen after the rotor rotation acting simultaneously and be sent to electrical generator inside through path and be used for dispel the heat (containing gear type); Nitrogen after the refrigeration also can import " secondary nitrogen " recovery system.

2. " " the same moving axis central inner of type can be hollow form to the same moving axis in center, and its part in cylinder suitably leaves hole, makes a part finish the nitrogen of merit because pressure, is used for heat radiation by delivering in the electrical generator with the hollow channel of moving axis; " edge gear transmission " type then requires its cylinder and generator casing to seal and to fuse, and refrigeration nitrogen is passed through;

F. the blade of rotor:

Be installed on the rotor (to rotor with to award air blade be not the situation of one), be used for accepting nitrogen " wind ", technical requirements: certain wind angle of awarding is arranged, be circle shape characteristics at this rotor, therefore to calculate the best wind angle of awarding, design concept and the thinking that can award air blade with reference to Principles of Steam Turbine and " vertical axis wind energy electrical generator ", too much argumentation do not done in this piece of writing;

The Blade Design of rotor also should meet the requirement of the principle of " wind-tunnel ".

Four. the nitrogen recycling system after the acting:

" secondary nitrogen " and the source:

Be by the nitrogen of " liquid gaseous state conversion decompression storehouse " is discharged to " cold driving annual ring ", finish the driving of rotor after exhausr port ejects and freeze from a/c system after nitrogen and be used for " secondary nitrogen " compressor cooling after the nitrogen of the common composition of nitrogen three be referred to as.The nitrogen of these three incoming roads, they have all finished the first time " task " separately, pass through the path of oneself " " secondary nitrogen " compressor " absorption system respectively by special use, this three road gas is pooled to this system " air-breathing " storehouse, pressurize once more through compressor, by the passage of " exhaling " gas storehouse through special use, deliver to the auxiliary jet of " four seasons valve ", by auxiliary jet once more to rotor penetrate have certain pressure " secondary nitrogen ", at this moment this kind nitrogen gas pressure may be lower than the original nitrogen gas pressure that positive nozzle penetrates, but it is still the propulsive effort of another incoming road, original liquid nitrogen driving gas is under the participation power-assisted of " secondary " nitrogen, will reduce " expenditure " greatly, and then save original nitrogen, and the propulsive effort of rotor does not reduce under the adjusting of computer, like this, just prolonged the supply time of original liquid nitrogen effectively, the storage level of original liquid nitrogen that equaled covert increase is because of being that recovery earlier is utilized admittedly once more and is called " secondary nitrogen ".Electrical generator also should be listed in wherein with nitrogen its nitrogen that loops back that freezes, and this needs electrical generator is sealed, and forms the loop.

" breathing " formula " secondary nitrogen " compressor assembly:

The major part title and the function of this system:

Vehicular accumulator cell 2. special uses " secondary nitrogen " compressor 3. compressors " exhale. inhale " gas tank

4. " secondary nitrogen " the refrigeration of intake and exhaust channel 5. " secondary nitrogen " compressor assembly of compressor

1. Vehicular accumulator cell:

The storage battery that adopts is wanted can to accomplish to charge at any time and is not influenced its work when charging, because, the charging of this kind battery provides charge power supply at any time by vehicle-borne electrical generator, generally speaking, as long as electrical generator sends enough electric power, (through certain device) just can finish charging, guarantees that storage battery has sufficient electric energy constantly.

The effect of storage battery and requirement have two:

● under " cold driving " for some reason can not the situation of powered vehicle, " battery traction " pattern that also can rely on the electric energy of its deposit to enter under computer or artificial scheduling that is: became now electronlmobil, answers acute driving;

● under the situation of generator powered, the electric energy that it had will satisfy the electricity consumption needs of compressor assembly fully, must be with using with electric energy supplement, because, compressor will cooperate the ventilation work of " cold driving annual ring " constantly, and therefore, cost should be used storage battery capacious if allow as far as possible.

2. special-purpose " secondary nitrogen " compressor:

Exhausr port and refrigeration system according to " cold driving annual ring ". the nitrogen that the personal refrigeration of compressor back is discharged. the freeze total amount of " secondary nitrogen " that used nitrogen etc. produced of electrical generator. pressure index, the corresponding compressor of special design, its technical data to fully satisfy " secondary nitrogen " and absorption and supply pressure, existing compression mechanism technology for making can fully be accomplished these, as piston compressor etc., but to the noise of compressor in addition actv. lower measure, this paper does not do too much narration;

The specific function that this compressor possessed:

* make full use of the refrigeration needs that original nitrogen " resource " satisfies self, this is the congenital advantage that general compressor does not have, and the degree of refrigeration can be accomplished very low;

* for compressor owing to possess good refrigeration condition, the quality of its compression " secondary nitrogen " or say that pressure can reach desirable effect, be general compressor can not accomplish;

This compressor is because the requirement of job specification: however the exhaust requirements that satisfies " cold driving annual ring " and refrigeration system (refrigeration that contains self) of stopping has coherent periodical duty process, should do following consideration during design:

A. the compression after " secondary nitrogen " is by the auxiliary jet of " nitrogen four seasons valve ", acts on the rotor once more; It is to be promoted under the situation of rotation by the original nitrogen of main nozzle at rotor, participate in doing work, as long as its propelling thrust can be kept rotor " " the operation of cruising, certainly the jet of main nozzle still carrying out, just gas consumption has reduced accordingly, therefore, only require that compressing function incites somebody to action " " be pressurized to certain degree gets final product secondary nitrogen, and this is the purpose for the accumulators conserve energy.Under the prerequisite of the needs that satisfy whole electricity consumption department, rotor " go the rounds " if the time auxiliary jet jet strength be that very desirable final result-main nozzle becomes temporarily greater than main nozzle " auxiliary jet ", but main nozzle should not stop air feed fully, just part stops or reducing, as: in four nozzles, two jet two rests in addition or total jet amount take the circumstances into consideration to reduce;

B.a. the work of compressor must be kept the on-cycle process, and air-breathing and neither can the stopping of exhaling is equivalent to a compressor, two storage tanks (even also will set up several).Reach certain setting pressure when the air-breathing compression in first storehouse, the drain tap in the storehouse is opened by passage and is supplied gas to auxiliary jet, and opposite merit is done with Jia Cang in the second storehouse simultaneously, and the air feed that hockets is realized the circulation of " breathing " formula;

B. can use power frequency and converter technique to compressor, in particular cases possesses handoff functionality freely, guarantee the continuity of air feed, also can allow the motor speed of compressor control and regulate running by supply gas pressure, allow the supply gas pressure and the rotating speed of air compressor form Dynamic matching, reach the normal operation that both keeps air compressor, reduce the actual horsepower input of electrical motor again, the energy of the storage battery that avoids waste;

Compressor " exhale. inhale " gas tank:

4. the intake and exhaust channel of " secondary nitrogen " compressor:

So-called " exhale. inhale " gas tank and bonded assembly intake and exhaust channel thereof are " secondary nitrogen " configuration section of compressor;

A. " exhale. inhale " gas tank by compressor with each road " secondary nitrogen " compile. store. be compressed to relative " suction " gas tank or " exhales " to go out in the auxiliary jet of " nitrogen four seasons valve ", realization utilizes original nitrogen again, otherwise, original nitrogen will be by the exhausr port of " cold driving annual ring " row to atmosphere, thereby strengthened the driving use amount of original nitrogen, caused a large amount of wastes." breathing " capacity of jar. the configuration of pressure and electrical motor, can design according to existing air compressor theory and technology, this paper does not do too much argumentation;

B. the intake and exhaust channel of " secondary nitrogen " compressor: be " breathing " jar advance. exhausr port or claim valve, and the designated lane that is connected with auxiliary jet in " nitrogen four seasons valve ", should consider to have heat insulation during design. pressure-proof function, its diameter. length should be complementary with actual operating conditions.

5. the refrigeration of " secondary nitrogen " compressor assembly

The refrigeration configuration effect of native system be " secondary nitrogen " and in compression process owing to will emit certain heat, no matter the heat of being emitted has what, the one, should reduce the release of unnecessary " heat " from the angle requirement of environmental pollution; The 2nd, cold driving has very convenient ready-made " refrigerant " source, and " reprocessing " still can one of originate as " secondary nitrogen ", and refrigerating capacity and effect should be very desirable through simple after importantly this " refrigerant " utilized.

The requirement of designing technique:

A. draw the path of a special use through " Tai Ji door " from " original liquid nitrogen transportation storage tank ", to " secondary nitrogen " " breathing " jar skin of compressor, because the pressure of " original liquid nitrogen transportation storage tank " is very high, its original liquid nitrogen need not the external world and exerts pressure in addition and can be advanced into cooling cycle system certainly, according to existing refrigeration principle and technology, the running of freezing under the control of computer arranges out the nitrogen after the refrigeration to get back to simultaneously " suction " conduct of the gas storehouse " secondary nitrogen " loop in one of source.

B. the release consumption of refrigerant should be decided on the compressor actual needs, according to the data of calculating determine in advance " amount ", warp " Tai Ji door " operates under the control of computer;

Five. the generator system of cold driving:

Native system is to realize the ultimate parts of cold driving---electrical generator is the design at center.Electric energy generated and stability are held the balance; Through the drive of coaxial drive axle, the rotor of electrical generator rotation cutting magnetic line sends electric energy.According to it is that vehicle-borne characteristics require electrical generator not only volume is little, and it is big that electric energy generated is also wanted.The design of electrical generator. select for use and should select according to the best theory of electrical generator subject in the world today, this paper no longer discusses.What deserves to be mentioned is:

● the mechanism of power generation cold air of native system is to be finished by the nitrogen after the work done in " cold driving annual ring ", if conditions permit should consider to reclaim this part nitrogen (also may sneak into the air that contains small amount of moisture owing to the circulation path imprecision here certainly), it should be listed in " secondary nitrogen " compressor and inhale the object that (returning) receives;

● if above refrigerating method is undesirable, also can directly use original nitrogen to carry out brute force refrigeration, (with reference to the method for air-conditioning or compressor recovery system);

Nitrogen after using vehicle-borne original nitrogen resource or utilizing work done carries out the electrical generator heat radiation, its effect compares water-cooled. and air-cooled technology will good manyfold, naturally also created good condition for the multiple electricity of electrical generator, under situation about reclaiming, imitative a/c system is removed in nitrogen loop after its refrigeration or compressor refrigeration system designs, and also will will connect " cold driving annual ring " and generator casing for " " type or " edge gear transmission " type get up with the channel seal that moving axis rotates the same moving axis in center;

Six. the electric energy that electrical generator sent mainly is the needs that satisfy following using electricity system:

Powered vehicle driving system 2. computerized control systems 3. of advancing " secondary nitrogen " and compressor 4. air-conditioning fans 5. other

1. drive the motor transmission agent that full garage advances:

The electric current that electrical generator sends send for respectively two motors through controller, the rotation of motor drives advancing (be used for twin shaft and drive car) of full car, controller one end promptly is " throttle " of so-called automobile by pilot control, moving also available manual manipulation can tramp with one's feet, the different magnitude of voltage that the size variation of " throttle " allows controller detect, controller is according to the size of magnitude of voltage, and analog regulation flows to the voltage height of motor, thereby has controlled rotating speed of motor.Other is as controller electrical equipment specification, controller function, and brake, automatic cruising, intelligent overcurrent, under-voltage protections etc. can design with reference to the theory of electronlmobil, and this paper is not discussed.

2. computerized control system:

Setting up of computerized control system is the absolutely different sophisticated design of vehicle operating with former use " heat drive " technology, also is one of cold driving characteristic; The layout in the operator's compartment and the layout of operating equipment are also just fully different, more comfortable.

Native system is that the commander of full car transfers the center, and all design-calculated programs all must be very tight. optimization is rational.Each system that computer control relates to and the sensitivity of parts will have high reliability to be complementary with it; Theory and technology in conjunction with modern state-of-the-art computer design and manufacturing is rationally programmed the actual conditions of the running of each each parts of system, and data setting is accurate, and the characteristics that are different from indoor computer environment for use below noting:

A. owing to the importance of this system, that is: to full car integral body, centralized computer all should be to start shooting at first and last shutdown in any case, so, guarantee that the continuity of its electricity consumption is extremely important! Power supply should have two kinds of approach sources: the one, provide by vehicle-borne electrical generator; The 2nd, provide by storage battery, comprise full car under static state, also can the normal operation running.(the specific design method slightly)

B. the arithmetic speed of centralized computer is very high, be connected firmly reliable with each corresponding position, corresponding lightning protection should be arranged. against shock. anticollision. anti-cold. heat. durable, compared with indoor computer work environment very big difference is arranged after all, so all designs should be considered fully.The simple of hommization wanted in the centralized computer operation, realizes " screenization " management in car, makes things convenient for the operation of chaufeur,

C. set up the conversational system translation function of at least three kinds of language, be convenient to popularize.

3. " secondary nitrogen " compressor

The electricity consumption of " secondary nitrogen " compressor mainly is the electrical motor of its preparation, is one of large electricity consumer of full car, reduces its electricity consumption as far as possible and be very important techniques means;

One of method: be exactly the purpose that the actual horsepower input that reduces electrical motor just can reach the consumption that reduces electric energy.

Should accomplish during design that rotating speed of motor controlled by total amount (air feed) pressure in " secondary nitrogen " source, compressor needs great power, and motor is just exported much power, and needn't flog a dead horse;

Its two: if feasible, adopt frequency control promptly to realize the purpose of speed governing by changing the electric electromechanics source frequency;

Its three: also to consider the free handoff functionality of frequency conversion and power frequency,, guarantee to provide the reliability of " secondary nitrogen " power in case the frequency conversion system et out of order can switch under the power frequency state work immediately.

4. freeze and air-conditioning fan

All relate to refrigeration work assembly its refrigeration after the nitrogen loop be mono-, promptly only be recycled to " suction " road in the gas tank of " secondary nitrogen " compressor, in other words wherein by " secondary nitrogen " air-breathing jar of inspiration, have only " secondary nitrogen " compressor can not work for some reason, just the venting valve limited row under certain pressure who is reserved by refrigerating cycle terminal separately can not work for some reason to the machine that contracts, just the venting valve of being reserved by refrigerating cycle terminal separately under certain pressure limited row to atmosphere.Each the bar refrigeration path and the path of supplying gas all should have heat insulating function.

Energy-conservation and the selection of air-conditioning fan is looked concrete situation and is determined by circumstances.(summary)

Other

Comprise: various car lights, door and window, the energy-conservation advance of the electricity consumption of rain brush or the like parts all need be included general design in.(summary) illustrates: if at engine and coal and oil power field, application of the present invention is more more convenient than above-mentioned automotive field.Reason:

1. relative big in its available space, less-restrictive;

2. the carrying capacity of its liquid nitrogen can more significantly increase, and is the work that the prolongs electrical generator condition that provides the foundation;

3. the fuel oil fire coal is replaced, no matter is that environment or resource itself are exactly a kind of benefit.

More than six parts be the full contents of technical scheme that the present invention adopts.

The comparison of " cold driving " principle and current " heat drives " principle beneficial effect

1. cold and hot driving obtains the employed resource of propulsive effort relatively:

A. well-known: " heat drive " principle will be used the oil that stores on the earth for the energy that obtains propulsive effort. coal. etc. resource, from between means of deliverys such as automobile train invention that day of using " heat drives " principle so far these more than hundred years, above-mentioned resource use on a large scale and consumption allows the mankind feel that resource is faced with exhaustion and is difficult to regeneration, " heat drives " is again the human main means that obtain propulsive effort, and then cause a series of problem: contention resource even produce a war, it is moving that capital market big sprinkled, and unconfinedly steps up exploration and exploitation etc.;

B. " cold driving " propulsive effort of obtaining is the liquefaction nitrogen of the air got, if technological means allow also can be directly with air luquefaction for use, importantly using these gases returns again to air, in overall process, do not change any chemical constitution of air, really realized from air, getting back to again the theory of going in the air; Air is ubiquitous easily available, produce the angle of these " original nitrogen " technological processes from purifying air, it is the process that the air to the dirt of ours at one's side purifies, it is worthy of note: though this intermediate consumption a large amount of electric energy, but than the problems referred to above and stake that it " heat drives " runs into, its meaning is self-evident.Reason is very simple: as long as you seek out health extra propulsive effort (energy) in addition, you must take out certain capital and exchange (no matter you are with what form or method) for; One of the capital of " heat drives " is to have sacrificed environment and consumed natural resources, and " cold driving " but is to concentrate (production liquid nitrogen) to consume certain electric energy in advance, and no longer emits unnecessary driving heat and toxic and harmful behind automobile starting; This just looks like the mode of current " concentrated supply of heating in the city ", producing these electric energy that liquid nitrogen consumed exactly can be utilized again, directly reduced the input of capital, soon the huge heat energy that is produced in the production process utilizes the principle of " hot air rising " to generate electricity again; Be not afraid of greatly so produce the factory of liquid nitrogen, and the requirement of " cold driving " universal back liquid nitrogen is very big, just in time is complementary and brings out the best in each other;

2. the environment potency ratio of cold and hot driving principle is:

A. fact proved: " heat drives " brought huge harm for our this celestial body, nowadays you want to look for good " pure land " of ecology to make one's options and can not arbitrarily be easy to get, directly cause the pollution of atmosphere, to various poisonous and hazardous gases of airborne release and objectionable impurities, huge interests and benefit have been brought though use this principle to us, but, from the living environment state that the present mankind faced, also brought the threat of huge survivability, (factor that also has other certainly) to us.Because burning will exhaust oxygen and discharge carbon dioxide. the impossible again hundred-percent utilization of Ran Shao heat simultaneously, always there are some heats to be run away both to emit unnecessary heat and come to heat to the earth, and carbon dioxide just as a pot cover lid on earth, cause earth intensification day by day, we also see and have felt that also temperature is more and more higher, (especially in summer), typhoon is stronger and stronger. the floods drought. multiple disease. sandstorm. dirt of air or the like, and " heat drive " direct or indirect aggravation these disasters;

B. " cold driving " to use a large amount of electric energy except producing in the liquid nitrogen process, other just are not configured to the needs of outer power consumption in all fields again, and are further perfect if " secondary nitrogen " recovery technology obtains, its pollution to environment should be zero; After being popularized (＜heat drive〉vehicle a large amount of stepping down from the stage of history except that special requirement), its benefit to environment will be self-evident, that our employed vehicle can become is real " environmental friendliness " and carrier and instrument;

3. the comparison of the economic aspect of cold and hot driving principle

A. the gasoline of " heat drive ". the diesel oil equal energy source is from exploring from underground extraction oil. and refine and produce to finished product etc., the process in each step all need support by money, although production technology all has the not raising of degree, but the input quantity of money is very big, must say this resource is arranged oneself, finished product price restraining factors are very many, what be worth proposition is: people are in order to remedy the deficiency of gasoline, diesel, unexpectedly use these fuel of grain-production, one case fuel oil of every product (referring to vehicle-mounted fuel tank) will exhaust an average people's the grain ration in 1 year unexpectedly, and the on short commons people of underdeveloped country is also a lot.

B. " cold driving " employed liquid nitrogen almost can be produced everywhere, and technology of producing and more and more advanced person and simplification of method, this means the reduction of cost, if the heat energy of being emitted in the production process is utilized to generating again, the price of popularizing the back liquid nitrogen will become the product of material benefit; The most important thing is does not have resource problem, its following factor that does not have restriction;

4. the application background of cold and hot driving principle is relatively:

" heat drives ": the world today is widely used, be accompanied by its pollution and resource problem to environment, people have set about the various improvement in addition of its application engineering, and made significant headway, the appearance of the vehicle of simple the electric power, the source of electric energy (no matter how) brought a linear light bright for the world of " driving ", but because its contained electric energy problem, stroke distances has become the resistance of its development;

" cold driving ": existing oneself nitrogen flooding power resources have the power reserve of Vehicular accumulator cell again, its power resources are sufficient, two-way, be real walking on two legs, this just means that also stroke distances is far away than elec. vehicle, importantly replenishing of its liquid nitrogen should be as " heat driving " group refueling, and be convenient and swift, adds layout that " liquid nitrogen " stand when the time comes also just as present petrol service station; " cold driving " is the pneumoelectric product in the tunnel that combines of liquid nitrogen and storage battery.

5. the comparison of the application civilization degree of cold and hot driving principle:

A. during " heat drive " is used except contaminated environment, also have peculiar smell to a certain degree. defectives such as greasy dirt, ground stain is very indecency and this is a common phenomenon during leakage of oil, if judge when driving that the various faults that vehicle or driving engine occur are the experience that only relies on accumulation generally speaking, and this needs the time to be enriched gradually for new hand, and its accuracy for failure judgment has just varied with each individual;

B. the defective of liquid nitrogen cold drive power above except not having " heat drive ", also owing to used computer technology, make chaufeur drive and daily maintenance process in cleaner and civilized; Put in place more and promptly and accurately to the action of various driving techniquies with to the understanding of vehicle operation situation, because the timely prompting and the help of computer are arranged, this understands the instant eliminating of the situation and the fault of vehicle operation constantly for chaufeur, having certain perspective and reliability, is that general " heat drives " experience institute is irreplaceable; Should say that this is in " driving " world, " heat drive " is from the progress of a milestone significance day by now of births;
