The utility model has the advantages of high cooling efficiency, long service life, good reliability, good fuel economy, accurate engine water temperature control, small engine water temperature fluctuation, easy maintenance and low cost, therefore the cooling system can be widely used in close type forced circulation water-cooling engines of various types.
Description
Technical field
The utility model relates to engine-cooling system, is mainly a kind of flow deviding type engine-cooling system, is applicable to the diesel engine for automobile cooling system of every cylinder four valves.
Background technique
At present, vehicle diesel engine adopts enclosed pump circulation water cooling system conventionally, when engine operation, through the cooling liquid of the cooling waterpump pressurization water jacket of engine cylinder of first flowing through, the parts such as cooling air cylinder sleeve, then the water jacket of engine cylinder cover of flowing through, the high-temperature area of cooling air cylinder cap.Cooling liquid flows along engine water jacket, and temperature raises gradually, so the coolant temperature of the block jacket of flowing through is lower than the coolant temperature of the cylinder head of flowing through.The water channel of cooling liquid between cylinder block and cylinder head flows to cylinder head jacket by block jacket, and the position joining at aforementioned water jacket is sealed by the waterstop ring of cylinder head gasket.
There is following shortcoming in such cooling system:
1) cooling reliability and the charging efficiency of ensureing that engine cylinder cap need to be strengthened, and engine cylinder cylinder sleeve needs the cooling liquid that temperature is higher to come the temperature optimization burning of lifting cylinder cover internal face and piston lubrication, and the coolant flow mode of at present traditional engine-cooling system is that in block jacket, coolant temperature is relatively low, in cylinder head jacket, coolant temperature is relatively high.
2) waterstop ring of engine cylinder cap pad adopts rubber material conventionally, and this regional temperature is high, is subject to oil and the corrosion of cooling liquid stronger, the easy ageing failure of rubber, the fault such as cause that motor leaks.So cylinder head gasket cannot reach higher working life.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of flow deviding type engine-cooling system, its structural design is ingenious, design two relatively independent cooling water channels cooled engine cylinder block and head respectively, promote the cooling effect of engine cylinder cap and cylinder block, promote engine reliability and working life, optimized Fuel Economy.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of flow deviding type engine-cooling system, include be arranged on cylinder cap assembly inside water jacket of engine cylinder cover, be arranged on the water jacket of engine cylinder of engine cylinder assembly inside, and cooling waterpump, it is characterized in that: the cooling line on described cooling waterpump water outlet is communicated with two branched pipes, and two branched pipes are communicated to respectively the water inlet of water jacket of engine cylinder cover and water jacket of engine cylinder; On the water outlet of described water jacket of engine cylinder cover and water jacket of engine cylinder, be communicated with respectively outlet pipe, two outlet pipes are communicated to respectively the water inlet of thermoregulator assembly one and thermoregulator assembly two; Major cycle water outlet on described thermoregulator assembly one and thermoregulator assembly two converges the water inlet that is jointly communicated to a radiator by pipeline, the short circle water outlet on described thermoregulator assembly one and thermoregulator assembly two is by converging the water inlet that is jointly communicated to described cooling waterpump connecting tube; The water outlet of described radiator is communicated to the water inlet of described cooling waterpump by return pipe.
On described thermoregulator assembly one and thermoregulator assembly two, set different open temps.
The utility model adopts two relatively independent cooling water channels, cooled engine cylinder block and head respectively, two independent cooling water roads share a cooling waterpump and a set of external heat removal system, and in two relatively independent cooling water channels, independently thermoregulator is set respectively, major cycle water outlet and the short circle water outlet of two independent temperature devices converge respectively, and connect respectively radiator water inlet and water pump water inlet, simultaneously two independently thermoregulator designed different structural type and different open temp characteristics.
The utility model has the advantages that:
(1) engine cylinder and cylinder head are cooling respectively, the cooling liquid inlet temperature of any operating mode lower cylinder body water jacket and cylinder cover water jacket is all identical, solve the shortcoming of traditional cooling system gas cylinder cover water jacket cooling liquid inlet temperature higher than block jacket cooling liquid inlet temperature, engine cylinder cap cooling effect be can promote, engine reliability and working life promoted.
(2) water jacket of engine cylinder and cylinder head jacket change parallel connection into by traditional series connection, engine cooling water roadlock power significantly reduces, and ensures that, in the situation of identical pump capacity, water pump consumed work can significantly reduce, reduce engine accessory power rating consumed work, improve Fuel Economy.
(3) cooling liquid, by the direct air inlet engine cylinder head jacket of pump outlet, can promote the cooling liquid absolute pressure in water jacket of engine cylinder cover, promotes cooling liquid boiling point, reduces cylinder head jacket wall vaporization tendency, promotes cooling effect.
(4) cylinder block and head cooling water channel can mate respectively different thermoregulator structure and open temp, engine water temperature is regulated more accurate, and fluctuating temperature is less.
(5) cylinder head gasket need not design water shutoff circle again, greatly improves reliability and the working life of cylinder head gasket, promotes motor machine life.
(6) two relatively independent cooling water channels share a cooling waterpump and a set of external heat removal system, and system architecture is simple, cost is low.
