Description
【Technical field】
The utility model relates to a kind of energy conversion power device more particularly to it is a kind of by gas pressure can and thermal energy turn
Turn to the power device of mechanical energy and the application of the device.
【Background technique】
It is understood that thermal energy is directly translated into there are many power devices of mechanical energy.Such as：Internal combustion engine, external-combustion engine, vapour
Turbine, aero-engine, rocket engine, missile propulsive plant etc..
For current thermal power reforming unit, major defect is：Exhaust temperature is high, fuel effective rate of utilization
Low, volume is big and heavy, and specific power is not high.Such as：By the internal combustion engine of working medium expanded by heating acting, there are three types of bases for hot merit conversion
This circulation.1. dual cycle；2. constant volume heat cycles；3. level pressure heat cycles.Since thermal cycle expansion is not thorough, or
Person's residual temperature is relatively high, and exhaust heat is relatively more (heat that engine exhaust gas takes away 30 ﹪ or more).And transformation mechanism
Structure is (such as：Crank link mechanism) volume is bigger and heavy.So that the specific power difficulty of power device gets a promotion.Although aviation
Engine, rocket engine, missile propulsive plant specific power is bigger, need to improve combustion gas to promote the propulsive efficiency of engine
Temperature and pressure.But the leaving velocity residual temperature of tail gas is also high, makes effective use of the thermal energy of fuel not.In addition by temperature and
The elevated temperature strength promotion of pressure influence, material is limited.
To solve the above-mentioned problems, there has been proposed pinking formula energy transformation power devices.Such as：Russia's liquid pulse detonation
Engine specialized laboratory, the academy of sciences of Russia Novosibirsk pressgang connect season Prokofiev fluid dynamics research Moscow aeronautics in one's power
Institute etc. studies successful pulse-knocking (being exactly to explode in mechanism) aero-engine for 2016.Exactly pushed away using Fuel explosion generation
The aero-engine of power, the common compressor burning of thermal efficiency ratio is one times high.Explosion and the essential distinction burnt are：Occur
Explosion the time required to most it is short can microsecond, and burn generally in signa or so.Explosion can generate very big wink
Between pressure and temperature, can make thermal energy be converted into greatest extent gas molecule flowing kinetic energy.In explosion generating process generally not
Controllable, and shake bigger with noise.So in practical applications must be controlling these factors.
Explosion is divided into physical explosion and chemical explosion.Physical explosion is due to colliding, the explosion that the reasons such as pressure is excessive generate,
Chemical explosion is since chemical reaction generates the explosion that huge energy generates.And the explosive effect described in us is exactly energy at certain
Assemble in one closed local cell domain and increases, when reaching a certain pressure threshold value, energy discharges suddenly in a very short period of time,
Explosive effect is generated, just as high pressure balloon explodes suddenly.Experiments have shown that in the feelings of the temperature and pressure without improving gas
Under condition, explosive effect can make the thermal energy of gas or pressure energy be converted into the kinetic energy of gas molecule flowing to the greatest extent, therefore go out
The phenomenon that existing gas temperature significantly declines.The microscopic explanation of explosive effect is：When occur explosion time, institute's closed container (or
It is relatively closed) the powerful warm-up movement potential energy that occurs in moment of inner gas molecule, intermolecular potential energy effect is lower as being collected
Equally, in synchronization, same behavior, integrating action concentrates on the ordering behavior of a certain result to body " consciousness ", occurs all
The phenomenon that energy (molecule thermal energy, molecular potential etc.) is all concentrated to this result (kinetic energy that gas molecule flows), therefore occur
The phenomenon that gas molecule temperature (thermal energy) declines to a great extent.
And mechanical energy can easily be just converted into the way of impact high speed impeller by the kinetic energy of gas molecule flowing
, therefore thermal energy can be improved using explosive effect or pressure energy is converted into the transformation efficiency of mechanical energy.Secondly explosive effect energy
Great instantaneous power is generated, the frequency for controlling explosion can make power device obtain biggish specific power.
In order to guarantee the lasting generation of explosive effect and have continuity, it is necessary to there is a structure that can be iteratively produced unexpected " rupture "
It releases energy, and " healing " energy can be closed at once, and the repeating work of control can be facilitated.Generally balloon burst, cut
It can not just heal automatically again.And the technological difficulties for duration control effect of exploding at present are exactly the automatic healing after cut.
Constraint of the gas by closed container before exploding, restraining force moment is reduced to zero after explosion, in this way can quick release of energy
Again it is clear-cut thoroughly, while minimizing (namely pressure) cut could heal automatically, reformulate closed at the end of energy release
Space, however current valve can not accomplish this point.
