Technical field
The present invention relates to field of internal combustion engine, more particularly to a kind of independent EGR (exhaust gas recycling) cooling heat radiation system.
Background technology
The internal combustion engines such as diesel engine and gas engine face SCR only and EGR routes when selecting discharge course, select EGR systems
The increase of engine water jacket heat dissipation capacity can be faced when system leads to the problem of the mating difficulty of vehicle.
The internal combustion engines such as diesel engine and gas engine face SCR only and EGR routes when selecting discharge course, select EGR systems
The increase of engine water jacket heat dissipation capacity can be faced when system causes the problem of the mating difficulty of vehicle, especially natural gas engine to select
When EGR routes, the problem is especially prominent.Because engine body heat dissipation capacity (it is assumed that) in the case of constant, engine EGR is high
Heat part caused by warm combustion gas needs to enter engine-cooling system to increase complete machine heat dissipation capacity.The present invention passes through
EGR independence cooling systems are designed, the increased heats of EGR is individually dropped and removes, engine radiating water tank area need not be increased, to
Improve engine suitability.Fig. 2 is the schematic diagram of the cooling system for recycled exhaust gas of the prior art.As shown in Fig. 2, the EGR systems of the prior art
The water return pipeline 22 of system is connected with the circulation waterway of engine body, that is to say, that altogether with the cooling system of engine
With.

The purpose of the present invention is to provide a kind of independent cooling system for recycled exhaust gas, to overcome the disadvantages mentioned above of the prior art.
To achieve the above object, the present invention provides a kind of independent cooling system for recycled exhaust gas, independently of the cooling system of engine
The cooling system of system, engine includes the circulation waterway of engine body, engine water return pipeline, engine radiating water tank, hair
Motivation inlet pipeline and water pump, independent cooling system for recycled exhaust gas include egr system, diversion pipeline, independent water return pipeline, independently dissipate
Boiler and independent inlet pipeline.Egr system is set in engine system；One end of diversion pipeline is connected to engine body
Circulation waterway, the other end be connected to egr system；Independent water return pipeline one end is connected to egr system；Independent cooling water tank is returned with independent
The other end of water lines is connected to；Independent inlet pipeline one end and independent cooling water tank, the other end are communicated in water inflow of the engine pipeline.
Preferably, in above-mentioned technical proposal, independent water return pipeline is not connected to the circulation waterway of engine body.
Preferably, in above-mentioned technical proposal, independent cooling water tank is the independent cooling water tank of egr system.
Preferably, in above-mentioned technical proposal, independent cooling water tank is to share cooling water tank.
Compared with prior art, the present invention has the advantages that：After being cooled down using independent EGR, egr system is brought
Additional thermal energy do not enter the cooling system of engine, but individually enter independent EGR but system radiate, need not start
Machine configures the water tank of the fan and bigger of bigger, increases engine matching, reduces complete machine cost, increases engine competitiveness.

As shown in Figure 1, Fig. 1 is the schematic diagram of independent cooling system for recycled exhaust gas according to the present invention.It is embodied according to the present invention
A kind of independent cooling system for recycled exhaust gas of mode, independently of the cooling system of engine, the cooling system of engine includes engine
Circulation waterway 1, engine water return pipeline 31, engine radiating water tank 3, water inflow of the engine pipeline 32 and the water pump 11 of ontology.
Independent cooling system for recycled exhaust gas include egr system 2, diversion pipeline 21, independent water return pipeline 41, independent cooling water tank 4 and it is independent into
Water lines 42.Egr system 2 is set in engine system；The circulation waterway of one end connection engine body of diversion pipeline 21
1, the other end is connected to egr system 2；41 one end of independent water return pipeline is connected to egr system 2；Independent cooling water tank 4 and independent return pipe
