Description
Technical field
The present invention relates to the heat-exchange device of a kind of technical field of internal combustion engines, particularly a kind of coolant making oil sump machine oil quickly heat and machine oil heat-exchange device.
Background technology
In the running of internal combustion engine, machine oil is requisite.Machine oil has cooling, lubrication, cleaning, seals four big functions, and it plays vital effect for ensureing that electromotor works normally.Electromotor in the running, if some friction positions can not get suitable lubrication, will produce dry friction.It was verified that the heat that dry friction produces at short notice is enough to make metal molten, the damage that causes parts even stuck (many leak or the fault such as scuffing of cylinder bore, axle suspension bush occurs in the automobile of leakage of oil, main cause is that this).Therefore good lubrication must be given to the friction position in electromotor.When after lubricating oil stream to friction position, one layer of oil film of formation on friction surface will be sticked to, reduce the resistance between friction parts, and oil film strength and toughness are the keys playing its lubrication.The heat that fuel produces after burning in electromotor, only sub-fraction is for the driving of power output and frictional resistance consumption and auxiliary body, and all the other major part heats, except being discharged to air China and foreign countries with waste gas, also can be taken away a part by the cooling medium in electromotor.Heat unnecessary in electromotor must discharge body, and otherwise electromotor can be too high and burn out due to temperature.This completes by engine-cooling system on the one hand, takes to oil sump by lubricating oil on the other hand and distribute after the Surface absorption heats such as cylinder, piston, bent axle.
When electromotor runs at the Smaller load such as idling, warming-up, the oil temperature in oil sump is relatively low, and lubricant effect is bad, thus causing the moving component frictional resistance of electromotor relatively big, oil consumption is higher.In the prior art, but without ripe, energy-conservation oil sump machine oil automotive quick-heat system.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, it is provided that a kind of coolant and machine oil heat-exchange device, it is possible to make oil sump machine oil quickly heat.
nullThe present invention is achieved through the following technical solutions，Cylinder cap of the present invention、Cylinder body、Oil sump、Air inlet pipe、Exhaustor、Air filter、Compressor、Charge air cooler、Air throttle、Turbine、Catalysis bag、Deafener、Coolant fairlead、Coolant leads back pipe、Heat exchanger、Electromagnetic valve，Cylinder cap、Cylinder body、Oil sump forms the body of electromotor together，The gas outlet of air inlet pipe is connected with the air intake duct on cylinder cap 1，The air inlet of exhaustor is connected with the exhaust duct on cylinder cap，Air filter、Compressor、Charge air cooler、Air throttle is sequentially arranged in air inlet pipe，Turbine、Catalysis bag、Deafener is sequentially arranged on exhaustor，The water inlet of coolant fairlead、Coolant leads back the outlet of pipe and is all connected with engine-cooling system，Heat exchanger is arranged in oil sump，The outlet of coolant fairlead、Coolant leads back after the water inlet of pipe both passes through oil sump housing and is connected with heat exchanger，Electromagnetic valve is arranged on coolant fairlead，Electromagnetic valve is connected with engine electronic control unit.
Further, in the present invention, coolant fairlead, coolant lead back the outside of pipe and all wrap up insulation material, and heat exchanger is facial heat exchanger, and heat exchanger is immersed in machine oil.
Compared with prior art, the present invention have the advantages that into: the present invention is reasonable in design, simple in construction, and oil sump machine oil can quickly heat；At small load condition, engine friction is less, and oil consumption is relatively low.
