Embodiment
Embodiment one one kinds has the engine cooling and circulating system of shunting refrigerating function
Present embodiments providing a kind of engine cooling and circulating system with shunting refrigerating function, with reference to figure 1, it comprises:
Cooling fluid case 1, the cooling fluid that engine system is lowered the temperature by described cooling fluid case 1 for holding, and cooling fluid case 1 provides cooling fluid for water pump 2, it is specially water pump 2 cooling fluid to be lowered the temperature by being flowed in different parts by pipeline after the taking-up of pump in cooling fluid case 1, this wherein just comprises cylinder body 3, and the cooling fluid that namely water pump 2 pump takes out enters in the passage of cylinder body 3.
Cooling fluid can flow into cylinder head exhaust side water jacket 4 by the 2nd shunt conduit 19 after flowing out (cooling fluid enter cylinder body passage after) by cylinder body 3, simultaneously when cylinder head temperature is higher, block jacket 6 is flowed into by the first shunt conduit 18, and it is provided with the first diverting switch due to the first shunt conduit 18, the present embodiment adopts cylinder body thermostat 5, described cylinder body thermostat 5 can control the opening and closing of self under the control of engine temperature, therefore, when the temperature of engine needs cylinder body thermostat 5 to open, the cooling fluid flowed out by cylinder body 3 just can enter in block jacket 6 by the first shunt conduit 18, and then flow out through cylinder head air inlet side water jacket 7. the first diverting switch in the present embodiment is cylinder body thermostat 5, is paraffin formula thermostat, and it is by the open and close of paraffin perception coolant temperature control self.
The present embodiment also comprises the 2nd diverting switch mechanism, described 2nd diverting switch mechanism can according to coolant temperature, the opening and closing of self is controlled by vehicle ECU, the above-mentioned cooling fluid flowed out by cylinder head exhaust side water jacket 4 and cylinder head air inlet side water jacket 7 all can flow in the 2nd on-off mechanism, then is shunted again by the control of the 2nd on-off mechanism. 2nd on-off mechanism comprises: thermostat base 8, electronic thermostat 9, for the cooling fluid circulation circuit controlled, temperature sensor 11, for monitoring the temperature of cooling fluid, and well heater 12, for electronic thermostat 9 is heated and make thermostat 9 open. wherein, the structure of described thermostat base 8 is such as Fig. 2, shown in Fig. 3: described thermostat base 8 comprises mounting seat 88 and installs chamber 83 with electronic thermostat, thermostat base 8 is installed in cylinder body 3 by this mounting seat 88, electronic thermostat is installed chamber 83 and is solid-located with mounting seat 88, for installing electronic thermostat 9, simultaneously integrated in mounting seat 88 it is provided with cylinder head air inlet side interface 81, cylinder head exhaust side interface 82, oil cooler return water pipe 87 also it is provided with in the side of mounting seat 88, above-mentioned cylinder head air inlet side interface 81 is vented side interface 82 and is all connected with electronic thermostat installation chamber 83 with cylinder head, and directly it is connected setting with cylinder head air inlet side water jacket 7 and cylinder head exhaust side water jacket 4 respectively, oil cooler return water pipe 87 is directly connected oil cooler 14, install at electronic thermostat and the sidewall in chamber 83 is also provided with temperature sensor fixing hole 84, and heater mounting hole 85, it is respectively used to mounting temperature sensor 11, and well heater 12. in addition, also integrated on the thermostat mount pad 8 of the present embodiment it is provided with warm braw heat exchanger water-in 86, just can directly warm braw heat exchanger 13 be installed so when mounted.
Above-mentioned thermostat base 8 is located at all integrated to all open holess and water-in all over the body, considerably reduces the number of connection of the outer pipeline of cylinder, reduces the volume of whole cooling system simultaneously, and with season, the installation, maintenance of electronic thermostat 9 is convenient.
Due to the mechanism design of above-mentioned thermostat base 8, therefore the cooling fluid flowed out by cylinder head exhaust side water jacket 4 and cylinder head air inlet side water jacket 7 can enter thermostat base 8, then cooling fluid directly flows in warm braw heat exchanger 13 by the warm braw heat exchanger water-in 86 on thermostat base 8, namely cooling fluid directly flows through the 4th shunt conduit 21 in Fig. 1, and then enters in engine via oil cooler 14 and water pump 2 and cool; And if now the temperature of cooling fluid is not enough to be lowered the temperature by warm braw heat exchanger 13, namely when the temperature of cooling fluid is too high, electronic thermostat 9 meeting is controlled and opens, cooling fluid is by thermostat base 8 inflow radiator 10, namely the 3rd shunt conduit 20 in Fig. 1 is flowed through, and no longer flow in the 4th shunt conduit 21, flow back to cooling fluid case 1 after lowering the temperature eventually through scatterer 10.
In addition, in order to ensure turbo-supercharger 16 and the performance of charge air cooler 17, the present embodiment is also provided with the 5th shunt conduit 22, described 5th shunt conduit 22 is for being connected the water inlet of the water outlet of cylinder body 3 and turbo-supercharger 16, charge air cooler 17, and is provided with electron assistant water pump 15 in the 5th shunt conduit 22.
The concrete principle of work of the present embodiment is: during cold start-up, in order to rapid warming-up, reduce frictionloss, improving charging efficiency, increase air input, now the temperature of engine is lower, therefore cylinder body thermostat 5 does not reach open temp and do not open by paraffin perception coolant temperature, cooling fluid directly enters cylinder head exhaust side water jacket 4 by the 2nd shunt conduit 19 after water pump 2 pumps and cools, and makes cylinder body 3 temperature comparatively fast raise like this, and cylinder head temperature reduces.
Along with the continuous running of engine, engine temperature constantly raises, and when temperature reaches certain value, cylinder body thermostat 5 is opened, and cooling fluid a-road-through is crossed the 2nd shunt conduit 19 and cooled by cylinder head exhaust side water jacket 4; A-road-through is crossed the first shunt conduit 18 and is entered cylinder body thermostat 5, then enters block jacket 6 and cools, and the cooling fluid after having cooled directly enters cylinder head air inlet side water jacket 7 and cools.
Cooling fluid after having cooled enters thermostat base 8 after flowing out from cylinder head, the temperature of temperature sensor 11 Real-Time Monitoring cooling fluid, and send the temperature information monitored to vehicle ECU, when the temperature of cooling fluid can maintain the normal operation of engine, electronic thermostat 9 is closed, the cooling fluid entering thermostat base 8 directly enters warm braw heat exchanger 13 by the 4th shunt conduit 21 and cools, the cooling fluid that warm braw heat exchanger 13 flows out is cooled by the direct ingress engine oil cooler 14 of the oil cooler return water pipe 87 on thermostat base 8, cooling fluid case 1 is flowed back to after completing, complete circulation, and when engine cool liquid temp is too high, Temperature Feedback according to temperature sensor 11 integrated on thermostat base 8 monitoring is to vehicle ECU, the control that now well heater 12 receives vehicle ECU heats to rapidly electronic thermostat 9, electronic thermostat 9 is opened fast, cooling fluid is by the 3rd shunt conduit 20, flow directly into scatterer 10 through electronic thermostat 9 to dispel the heat, then flow back to cooling water tank 1, complete circulation.
In addition, when the temperature of turbo-supercharger 16 and charge air cooler 17 is also too high, vehicle ECU controls electron assistant water pump 15 and opens, and cooling fluid is incorporated into turbo-supercharger 16 by the 5th shunt conduit 22 and in charge air cooler 17, is responsible for turbo-supercharger 16 and charge air cooler 17 being cooled.
