Description
Technical field
The present invention relates to engine art, specifically a kind of vaporizer that boils for motor exhaust recirculation。
Background technology
Along with increasingly stringent and the enforcement of road vehicle Abgasgesetz, after Europe six Abgasgesetz is implemented, the year two thousand twenty by enter based on limit the CO2 carbon emission regulation discharged implementation phase。For this, the per 100 km fuel oil consumption of electromotor is proposed strict requirement and standard。For this, represent various Waste Heat Recovery technology with Rankine cycle for technology, become Shape Of Things To Come and reduce one of the maximally effective means and technology of CO2 discharge。
Meanwhile, the efficiency of energy utilization of electromotor is relatively low, is generally about 40%, and all the other heats of 60% scatter and disappear in a variety of manners and enter air。In electromotor various forms used heat, maximum with engine exhaust used heat proportion。And the organic Rankine bottoming cycle based on Waste Heat Recovery passes through the tail gas of electromotor and the used heat of waste gas recirculation EGR and cylinder sleeve of engine water to absorb, it is converted into Effective power output by decompressor, thus indirectly promoting Fuel Economy and the discharge of reduction CO2。
In the explosive evaporation device of engines exhaust gas recirculation, it it is the heat of Rankine cycle organic working medium-freon absorption high-temperature tail gas, while reducing recycled offgas again (cooler for recycled exhaust gas as traditional), absorb the heat of tail gas, it is achieved the conversion of waste heat energy regenerating and utilization。And in electromotor recirculation tail gas and freon coolant heat exchanging process, if there is product failure, causing that high pressure freon coolant leakage enters recirculation tail gas, this recycled offgas and coolant freon simultaneously enter burning in engine chamber again。In this combustion process, freon can react because of Pintsch process and with air, produces the gaseous matters such as severe toxicity cyanogen fluoric acid and discharges air, heavy damage and atmosphere pollution。
For this, in motor exhaust explosive evaporation device, freon is with exhaust gas heat exchange simultaneously, it is to avoid freon enters tail gas and engine combustion is indoor, one of design key point becoming motor exhaust explosive evaporation device。All adopt soldering processes through document patent No. US2012-0285167 and patent No. US2013-0205766, isolate tail gas and freon with plate, owing to solder joint is excessive, potential failure is very risky, once reveal, freon easily enters in recirculation tail gas, causes the discharge of electromotor violent in toxicity。
Summary of the invention
The present invention is to solve the problems referred to above that prior art exists, aim to provide the tail gas explosive evaporation device of a kind of superconductive heat transfer principle and plate-fin structure form, the heat exchange making freon and tail gas is isolated entirely from by hotplate technology, thus avoiding other dividing wall type shape heat exchangers once there is product failure, freon leakage is in recirculation tail gas。
For solving the problems referred to above, the present invention is by the following technical solutions: a kind of vaporizer that boils for motor exhaust recirculation, including by air inlet side end cap, give vent to anger side end cap, the exhaust gas heat exchange area that lower house and lower mainboard are constituted, the freon coolant heat exchange area being made up of upper shell and upper mainboard, the coolant inlet tube connected with described coolant heat exchange area and refrigerant exit pipe, many group hot plates and the fin being arranged alternately with described hot plate, it is characterized in that described hot plate is fixing after penetrating the perforation on described upper mainboard and lower mainboard, the evaporator section of described hot plate is placed in described exhaust gas heat exchange area, the condensation segment of described hot plate is placed in described coolant heat exchange area。
