Description
Technical field
What the present invention relates to is a kind of device of vehicle-mounted technical field of power generation, in particular a kind of device for generating power by waste heat of tail gas of automobile.
Background technology
Along with the high speed development of global economy, automobile is more and more universal, has been indispensable important component part in the modern life.But the vehicle fuel heat 1/3rd is an available energy only, use as power, second what its excess-three was divided is by cooling water expansion tank or exhaust mode exhaust to atmosphere, has not only wasted the energy greatly but also has polluted environment, how these energy being used, is people's questions of common concern.Utilizing generating power by waste heat of tail gas of automobile is to make full use of fuel energy as vehicle power, raises the efficiency environmental a kind of mode.Though this technology is dropped into research by people already, result of study is all also not overripened, and degree of utilization is very low.
Find through literature search prior art, Chinese patent literature number: CN2899274Y, this technology discloses a kind of device for generating power by waste heat of tail gas of automobile, on the final vacuum pipe energy converter is installed, and the electric weight mouth of energy converter connects the input end that automobile computer is eaten by adaptor union.During automotive engine work, by the tail gas of final vacuum tube drainage high heat.But because the exhaust gas flow speed of auto emission is very fast, the heat energy that this device absorbs is limited, causes energy utilization rate low, and actual using value reduces.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art; a kind of device for generating power by waste heat of tail gas of automobile is provided; pressure regulation is stored in automobile battery to the electricity that this device sends through regulating circuit; can support each power device electricity consumption on the automobile; easy to use; improve energy utilization rate, helped environmental protection.
The present invention is achieved by the following technical solutions, the present invention includes: front exhaust pipe, the final vacuum pipe, H Exch, pump, condenser, expansion engine, electrical generator, regulating circuit and automobile battery, wherein: the front exhaust pipe outlet links to each other with heat exchanger entrance, the final vacuum tube inlet links to each other with heat exchanger outlet, the inlet of H Exch links to each other with delivery side of pump, the inlet of pump links to each other with condensator outlet, outlet links to each other condenser inlet with expansion engine, the inlet of expansion engine links to each other with the outlet of H Exch, electrical generator links to each other with expansion engine, and regulating circuit links to each other with electrical generator respectively with automobile battery.
Described expansion engine links to each other by coupler with electrical generator.

The present invention compared with prior art has following advantage: the present invention utilizes high-temperature tail gas generating and store electrical energy; whole device has only pump to expend micro-electric energy; and the present invention is stored in automobile battery after electrical generator being utilized the pressure regulation of high-temperature tail gas electricity; the storage of electric energy and use more convenient; improved energy utilization rate; not only save the energy, and helped environmental protection.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated: present embodiment is to implement under the prerequisite in technical solution of the present invention.Provided detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
As shown in Figure 1, present embodiment comprises: front exhaust pipe 1, final vacuum pipe 2, H Exch 3, pump 4, condenser 5, expansion engine 6, electrical generator 7, regulating circuit 8 and automobile battery 9, wherein: front exhaust pipe 1 inlet is connected with the automobile engine tail gas discharge side, front exhaust pipe 1 outlet links to each other with H Exch 3 inlets, 3 outlets link to each other final vacuum pipe 2 inlets with H Exch, 2 outlets of final vacuum pipe link to each other with outside air, the inlet of H Exch 3 links to each other with the outlet of pump 4,5 outlets link to each other the inlet of pump 4 with condenser, 6 outlets link to each other condenser 5 inlets with expansion engine, the inlet of expansion engine 6 links to each other with the outlet of H Exch 3, electrical generator 7 links to each other with expansion engine 6, and electrical generator 7 links to each other with automobile battery 9 with regulating circuit 8 respectively.
This device starts behind the car engine, the high-temperature tail gas that automotive engine produces enters H Exch 3 by front exhaust pipe 1, pump 4 is with liquid refrigerant suction H Exch 3, high-temperature tail gas becomes low temperature exhaust gas for liquid working medium dissipated heat thermal energy exchange to be discharged in the outside air by final vacuum pipe 2 in H Exch 3, and liquid refrigerant absorbs heat energy and forms the high temperature refrigerant steam and enter expansion engine 6 by pipeline and make its rotation, expansion engine 6 drives electrical generator 7 generatings by coupler, automobile battery 9 is gone in storage after electricity process regulating circuit 8 pressure regulation that electrical generator 7 sends, and the High Temperature High Pressure refrigerant vapor was done and is become the low pressure working fluid steam after the merit and enter condenser 5 by pipeline and be condensed into liquid refrigerant, by pump 4 suction Hs Exch 3, automotive engine continues to start to continue to produce high-temperature tail gas and enters H Exch 3, so continue circulation, constantly produce electrical power storage in automobile battery 9, stop up to automotive engine.Have only pump 4 to expend micro-electric energy in the whole device, saved the energy to greatest extent, improved energy utilization rate, and help environmental protection.
