Description
Technical field
The invention belongs to UTILIZATION OF VESIDUAL HEAT IN, be specifically related to a kind of heat energy that reclaims in the engine exhaust gas, to improve the efficient of motor.
Background technique
In the energy that the automotive fuel burning is produced, nearly about 1/3rd are used effectively, and remaining energy is lost in the atmosphere, and wherein the lost energy of exhaust accounts for nearly 1/3rd.Therefore, effectively utilize the automobile exhaust gas energy to become an effective way that realizes vehicle energy saving.
At present automotive residual heat is recycled and is mainly contained several method, as: turbocharging technology, waste heat air-conditioning, utilize the exhaust energy thermo-electric generation, reclaim exhaust energy etc. based on Rankine cycle.But supercharging technology can only utilize the portion of energy of exhaust, and the exhaust of turbine outlet still has higher temperature, has value once more; The waste heat air-conditioning technical does not have the output of merit, and capacity usage ratio is low; Thermo-electric generation then is subject to the development of technology such as material, and conversion efficiency of thermoelectric is low; Reclaim exhaust energy based on Rankine cycle, system complex, volume and weight all is difficult to reach requirement.So said method all has its narrow limitation.The Stirling engine compact structure, but at present known its efficient of method of utilizing Stirling engine recovery automotive residual heat is low, proposition of the present invention can remedy the defective that the Stirling engine heat recovery exists, waste heat of internal combustion engine is fully utilized, when improving waste heat recovery efficient, vehicle fuel utilization factor is significantly improved.
Summary of the invention
The objective of the invention is, a kind of improved Stirling engine waste heat recovery plant is provided, the thermal power transfer that engine exhaust is gone out becomes high-grade mechanical or electrical energy.
Know-why of the present invention is, heat absorber is installed in the front end of exhaust manifold for internal combustion engine, and the heat of I. C. engine exhaust is exhausted mostly to be absorbed by the heat absorption working medium in the Stirling engine, and all the other heats enter environment.Cycle fluid in the Stirling engine heat absorber is compressed the regenerator heating of flowing through in compression chamber, enter heater and expansion chamber afterwards, and working medium adds thermal expansion and promotes the piston acting, and piston is driving generator work by a cover transmission system.The present invention utilizes heat that engine exhaust the goes out power resources as Stirling engine, and the heat absorber of Stirling engine is designed to the plate and fin type high-performance heat exchanger, and the Stirling engine work is used for driving generator or directly is coupled with engine crankshaft.For the heat of the absorption I. C. engine exhaust of maximum possible, the heat exchange of exhaust and heat-exchange working medium adopts faulting streamed, and promptly I. C. engine exhaust (air-flow) flow direction is vertical with channel cycle working medium flow direction.Adopt single layer separator to be spaced between cycle fluid passage and the grate flow channel, cycle fluid forms the U-shaped passage in the plate-fin heat exchanger runner.
Because the flow of cycle fluid is little more than the flow of exhaust, simultaneously in order to improve Stirling circuit efficient, should reduce the circulation volume of expansion chamber and compression chamber as far as possible, therefore the circulation area of " used heat " exhaust passage is 4～8 times of cycle fluid channel cross-sectional flow area.

Embodiment
Below in conjunction with accompanying drawing and by specific embodiment know-why of the present invention is further described.The waste heat recovery plant of utilization Stirling engine comprises internal-combustion engine, Stirling engine, generator etc.Stirling engine is made up of heat absorber, expansion chamber, regenerator, compression chamber, piston.The gas side of heat absorber 3 is joined in internal-combustion engine vent-pipe 1 and the Stirling engine 2, links to each other by one or several short tube between an end of heat absorber 3 working medium side and the expansion chamber 4.For present embodiment, an end of heat absorber 3 working medium side links to each other by a short tube with expansion chamber 4.The other end of heat absorber working medium side and regenerator 5 join, and power piston 6 is by a cover transmission system drives generator 7 generatings.Heat absorber 3 is designed to the plate-fin heat exchanger structure.For present embodiment, the circulation area of gas side canal is 6 times of working medium side channel cross-sectional flow area in the heat absorber 3.
The cycle fluid of Stirling engine is compressed regenerator 5 heating of flowing through in compression chamber 8, enter heater and expansion chamber 4 afterwards, cycle fluid is deflated in heater and adds thermal expansion, gas distribution piston 9 is up, 6 actings of propulsion power piston, thus the cycle fluid after the acting is finished a power cycle through cooler 10 coolings.Heater 3 is a plate-fin structure.Exhaust passage 11 is the individual layer interlaced arrangement with cycle fluid runner 12, and promptly I. C. engine exhaust (air-flow) flow direction is vertical with channel cycle working medium flow direction.All be furnished with fin 13 in the gas side runner with forced heat exchanging.
Characteristics of the present invention and remarkable result are that the thermal power transfer that engine exhaust is gone out becomes high-grade mechanical or electrical energy Export, be used for the auxiliary equipment of internal combustion engine with energy, such as air conditioner refrigerating, water pump, oil pump also can move by a cover with energy The merit that the couple of force locking device directly sends Stirling engine and engine crankshaft are coupled, thereby make the relative fuel oil of internal combustion engine Consumption rate effectively reduces.
