Abstract

A direct heat type engine is mainly characterized in that the device comprises a heat source, two circulating pumps, a heat motor, a power output mechanism, a radiator pipe and a liquid pipe: the heat source is interlinked with the circulating pumps and a heat exchange coil in the heat motor one after the other; an exhaust outlet of a vortex mechanism in the heat motor is connected with a cooling fin and the cooling fin is connected with the other circulating pump, the cooled outlet of the circulating pump is connected with the liquid inlet of the scroll plate of the vortex mechanism in the heat motor and the liquid pipe passes through the center of the heat exchange coil in the heat motor. In view of the shortage that the transformation efficiency of the thermal efficiency is lower and together with the vortex structure of the vortex mechanism and the characteristics of high valumetric efficiency and better dynamic balance, the liquid working medium is directly input into the central compression chamber of the vortex mechanism to be vaporized and swelled so as to drive the scroll for power output.

Description

Direct heatnig type engine

Technical field:

The utility model belongs to a kind of hot machine, especially belongs to a kind of direct heatnig type engine.

Technical background:

The common feature of hot machine is: fuel combustion discharges heat energy, these heat energy pass to operation material again---water vapor or combustion gas, after operation material obtains heat energy, expand and do work, a part of heat energy is converted into mechanical energy, the heat energy of operation material reduces simultaneously, and temperature reduces, and remaining heat energy removes with exhaust or heat radiation form.The existing internal-combustion engine of hot machine also has external-combustion engine, and the basic characteristics of internal-combustion engine are to allow fuel burn in the cylinder combustion of machine, generate the combustion gas of High Temperature High Pressure, utilize this combustion gas to go to promote actings such as piston or turbine as working medium.And fuel is outside cylinder or the burning of decompressor such as turbine, and the steam that the back that then certain is heated produces imports the hot machine of decompressors actings such as cylinder or steamer, is called external-combustion engine.Because hot machine produces discharging and heat radiation in the course of the work, so actual 35～40% the heat energy of only having an appointment is converted into useful mechanical energy output.Because present global energy shortage, the raising of efficiency of heat engine is very favourable to saving the energy.Simultaneously, scroll machine through years of development, has been obtained industrialized application after the initial stage in 19th century is proposed by French engineer's Peter Krass (CRUEX).Because scroll machine has plurality of advantages such as volumetric efficiency height, volume is little, noise is low, dynamical balancing is good, its application is more and more broader, the existing application at aspects such as air-conditioning, pumping liquid, pressurization gas also has scroll machine is applied to design on the motor as decompressor.The Vortical engine of this design belongs to the hot machine of external-burning type, by the external world high temperature and high pressure gas is imported and is allowed its acting outputting power that expands in the scroll machine.Its circuit thermal efficiency, mainly the increase with pressure increases, and the rising that can bring compression end of a period air high temperature when improving pressure, scroll machine is at high temperature worked like this, when particularly high-temperature gradient is worked down, the parts of relative movement will produce inconsistent linear expansion amount, cause the phenomenon of killing between movement parts easily.Simultaneously during hot operation, also can allow the greasy property exacerbated of scroll machine.So overcome these difficulties also is the key point that the vortex motor is achieved.

The model utility content:

The utility model is exactly the shortcoming at above-mentioned hot machine, in conjunction with the structural feature of scroll machine, solves scroll machine high temperature and kills problem, develops energy-efficient direct heatnig type engine.The utility model is directly imported the working medium of liquid state the flash evapn that is heated in the center compression chamber of scroll machine and is expanded, and promotes scroll work and outputting power.Because working medium is to expand in the heat absorption of the center of scroll compression chamber to do work, the torrid zone that produces during also with the scroll relative movement when discharge acting back is walked, when so both having solved the scroll relative movement owing to high temperature is out of shape the phenomenon of killing, also reduce the requirement of greasy property and high-temperature sealing material, thereby greatly reduced the production difficulty of direct heatnig type engine.Simultaneously and since the utility model system be directly with working medium with liquid state input rather than with the high temperature and high pressure gas input, can save the energy and the mechanism that make high temperature and high pressure gas, really realized energy-efficiently, reduce the target of manufacture cost.

Description of drawings:

Accompanying drawing 1 is the system construction drawing of present embodiment, comprising thermal source 1, recycle pump 2, heat exchanger coiled pipe 3, scroll 4, scroll 5, power take-off mechanism 6, heat radiation 7, recycle pump 8, hot motor 9, liquid entering hole 10, whirlpool dish liquid entering hole 11, liquid pipe 12, relief opening 13.

Embodiment:

Below in conjunction with drawings and Examples the utility model is further specified.

As shown in Figure 1, at first the delivery outlet with thermal source 1 is connected with the inlet of recycle pump 2, and the outlet of recycle pump 2 is connected with heat exchanger coiled pipe 3 inlets in the hot motor 9, and the outlet of heat exchanger coiled pipe 3 is connected with the inlet opening of thermal source 1 again, the formation thermal cycle.

The relief opening 13 of hot motor 9 links to each other with heat radiation 7, the inlet of heat radiation 7 outlets and recycle pump 8 joins, the liquid entering hole 10 of the outlet of recycle pump 8 and hot motor 9 joins, the liquid entering hole 10 of hot motor 9 coils between the liquid entering hole 11 with the whirlpool and links to each other by liquid pipe 12, form an expansion cycle, and liquid pipe 12 is to absorb heat by the center of heat exchanger coiled pipe 3.

Heat exchanger coiled pipe 3 is to place within the hot motor 9, with the main body of scroll 4, scroll 5, the hot motor 9 of liquid pipe 12 compositions.Simultaneously, heat exchanger coiled pipe 3 also can place outside hot motor 9 main body covers.

When system works, recycle pump 2 pumps into thermal medium in the heat exchanger coiled pipe 3 from thermal source 1, carries out heat exchange with liquid pipe 12, makes the working medium absorption heat in the liquid pipe 12 carry out preheating; The thermal medium that has been absorbed heat and has reduced temperature is circulated back to and absorbs the heat exchange circulation that heat goes round and begins again in the thermal source 1 again.In liquid pipe 12, absorbed working medium that heat carries out preheating enters into scroll by the dish liquid entering hole 11 of the whirlpool on the scroll 4 former center compression chamber, former compression chamber is expanded as expansion chamber and rapid therein evaporation heat absorption, promote scroll 5 motions, 6 of the power take-off mechanisms that links to each other with scroll 5 are exported power endlessly.The working medium of vaporizing simultaneously and having absorbed the scroll heat is discharged from the relief opening 13 of hot motor 9 and is entered heat radiation 7, heat left be condensed into liquid state, liquid working medium enters the center compression chamber heat absorption vaporized expanding of scroll again by liquid pipe 12 preheatings that recycle pump 8 pumps in the hot motor 9, the expansion cycle of like this going round and beginning again, power is exported endlessly, realized the stable power output function of motor.

In sum, the utility model has the following advantages:

(1) simple for structure: the utility model utilizes the characteristic of expanding with heat and contract with cold of working media, in scroll machine Heart compression chamber directly expands therein as expansion chamber and promotes scroll plate work, and having save provides the high temperature height The calm the anger equipment of body has been simplified greatly the structure of engine on the structure.

(2) the energy-conservation energy: direct expansion, can save the heat dissipation of high temperature and high pressure gas in course of conveying, reduced the waste of the energy.When working medium expands simultaneously mainly is the heat that has absorbed scroll machine itself, needs to want the extraneous heat that provides less, so the energy that heat is provided that expends is less.

(3) environmental protection: expand and finish the medium recirculated work of merit, a large amount of waste gas is not entered atmosphere environment, realize environmental objective.
