Fig. 1 a shows the embodiment's of cooling circuit 90 first perspective view, and cooling circuit 90 comprises internal-combustion engine 10, cooler for recycled exhaust gas 40 and retarder cooler 30.The exhaust of internal-combustion engine 10 can be transported to exhaust gas recycling system (egr system), and wherein cooler for recycled exhaust gas 40 coolings are from the exhaust of internal-combustion engine 10 dischargings.Internal-combustion engine 10 is coupled to the retarder 32 that is used for abrupt deceleration vehicle, and wherein retarder is by 30 coolings of retarder cooler.
Cooler for recycled exhaust gas 40 is connected to retarder cooler 30 and flows tandem arrangement with respect to freezing mixture.Fig. 1 b shows the embodiment's of cooling circuit 90 the view of reverse side.
Internal-combustion engine 10 adopts the coolant cools mode, and wherein freezing mixture is cooled in the coolant chiller 20 of a part that can be used as cooler casing 26.With reference to arriving Fig. 1 a and Fig. 1 b, freezing mixture for example water is transported to internal-combustion engine 10 at first end, 14 places of internal-combustion engine 10 through coolant entrance 45.Freezing mixture is discharged through freezing mixture delivery outlet 46 at second end, 16 places of internal-combustion engine 10.Coolant chiller 20, the first ends 14 that first end 14 of internal-combustion engine 10 can for example be arranged as near cooler casing 26 constitute the for example front end of internal-combustion engine 10.Can be arranged in coolant chiller 20 with first end, the 14 second opposite ends 16 and to separate the position of distance to a declared goal and to constitute the for example rear end of internal-combustion engine 10.Coolant chiller 20 comprises that radiator maybe can form radiator.
Air is passed coolant chiller 20 through fan 28 by suction, and said fan 28 is disposed in first end, 14 places of internal-combustion engine 10, for example is arranged in the front side of internal-combustion engine 10.At second end, 16 places, transmission device 22 followed are with gear-box 24 is arranged.Retarder 32 is installed to gear-box 24, and said gear-box 24 is arranged in second end, 16 places of internal-combustion engine 10, for example is arranged in the rear side of internal-combustion engine 10.
In the egr system of internal-combustion engine 10; Exhaust is transferred through cooler for recycled exhaust gas 40 and arrives EGR valve 58 from exhaust delivery outlet 56, and exhaust mixes with the fresh air of carrying through air conduit 70 (mode of breaking off with part illustrates) in EGR valve 58 and is transported to the intake manifold in the intermediate portion 12 of internal-combustion engine 10.Cooler for recycled exhaust gas 40 is disposed among the top 12u of internal-combustion engine 10.
Engine coolant is cooled in coolant chiller 20 and is transported to internal-combustion engine 10 through the pipeline 50 between the coolant inlet 45 of coolant chiller 20 and internal-combustion engine 10.
The pipeline 42b that the coolant fluid path 60 that constitutes the freezing mixture return pipeline between freezing mixture delivery outlet 46 and the coolant chiller 20 comprises the pipeline 42a that extends to retarder cooler 30 from freezing mixture delivery outlet 46, retarder cooler 30 successively, extend to cooler for recycled exhaust gas 40 from retarder cooler 30, cooler for recycled exhaust gas 40, the pipeline 44, the thermostat housing that extend to thermostat housing (being hidden in the internal-combustion engine foundry goods, invisible among the figure) from cooler for recycled exhaust gas 40 and the pipeline 48 that extends to coolant chiller 20 from thermostat housing.
If thermostat cuts out, freezing mixture can directly flow to the coolant inlet 45 of internal-combustion engine 10 through bypass connection 18.
The part in retarder cooler 30 and cooler for recycled exhaust gas 40 formation coolant fluid paths 60.Advantageously, cooler for recycled exhaust gas 40 and retarder cooler 30 are the full flow coolers that receive 100% the freezing mixture stream that flows out from internal-combustion engine 10.Because cooler for recycled exhaust gas 40 is arranged along the IC engine airframe of internal-combustion engine 10 as the cardinal principle straight portion in coolant fluid path 60; And be transferred first end 14 through cooler for recycled exhaust gas 40 to internal-combustion engine 10 from the freezing mixture of retarder 32 and retarder cooler 30, therefore can reduce the number of tubes that is used for ANALYSIS OF COOLANT FLOW.
The freezing mixture of cooling circulates through internal-combustion engine 10, retarder cooler 30 and cooler for recycled exhaust gas 40 and coolant chiller 20 successively in coolant chiller 20.
Although retarder cooler 30 and cooler for recycled exhaust gas 40 tandem arrangement in coolant fluid path 60; But at a time in the cooler 30,40 only one work, make at a time most of heat load only through in two coolers 30,40 one be introduced in the freezing mixture.When retarder 32 worked and need through 30 coolings of retarder cooler, vehicle was in deceleration regime.Under such operator scheme, exhaust is not recycled.When exhaust recirculation and when needing through cooler for recycled exhaust gas 40 coolings, internal-combustion engine 10 moves in retarder 32 inoperative more high-load range in egr system.Because the heat load of each cooler 30,40 is introduced in the different operating modes of internal-combustion engine 10, make each cooler 30 or 40 can higher heat load be incorporated in the freezing mixture and do not make the cooling effectiveness deterioration of other cooler 40 or 30.
The blast air of cooling is crossed pipeline 52 between exhaust outlet 56, is passed cooler for recycled exhaust gas 40 and the agent cooling and pass pipeline 54 and arrive EGR valves 58 of being cooled therein in cooler for recycled exhaust gas 40.Can be provided for making the exhaust by-pass valve of cooler for recycled exhaust gas 40 bypass, but not specify here.
With reference to Fig. 2, show according to preferred vehicle 100 of the present invention, said vehicle comprises the internal-combustion engine that has according to the cooling circuit 90 of the conveying freezing mixture of Fig. 1 a and Fig. 1 b.Vehicle 100 is preferably Lightweight Vehicles, medium sized vehicle or heavy vehicle, such as truck.
The present invention is owing to the large-scale pipeline of having avoided for example arranging along internal-combustion engine 10 allows a kind of very effective assembling, because cooler for recycled exhaust gas 40 (Fig. 1 a, Fig. 1 b) is the part of the freezing mixture return path from internal-combustion engine 10 to vehicle radiator.
