In figure, 1 engine, 2 cooling water incubators, 3 temperature-conserving valves, 31 cooling ducts, 32 non-cooled channels, 4 coolers, 5
Water pump.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples.
Refer to attached drawing 1, a kind of quick heat engine cooling system of automobile engine, including cooling water incubator 2, temperature-conserving valve
3, non-cooled channel 32 and water pump 5；Cooling water, the water inlet and cooling water incubator of temperature-conserving valve 3 are stored in cooling water incubator 2
2 water outlet connection, the water outlet of temperature-conserving valve 3 are connect by non-cooled channel 32 with the water inlet of water pump 5, the water outlet of water pump 5
Mouth is connect with the water inlet of engine 1, and the water outlet of engine 1 is connect with the water inlet of cooling water incubator 2, and cooling water is made to exist
Engine heat cycles are formed between engine 1, cooling water incubator 2, temperature-conserving valve 3 and water pump 5.
The quick heat engine cooling system of the automobile engine further includes cooler 4, and cooler 4 passes through cooling duct 31
It is connected between temperature-conserving valve 3 and water pump 5, makes cooling water in engine 1, cooling water incubator 2, temperature-conserving valve 3, cooler 4 and water
Engine cool circulation is formed between pump 5；It can be by connecting temperature sensor detection cooling with automobile ECU (electronics execution unit)
The water temperature of water incubator 2, the temperature-conserving valve 3 are connect with automobile ECU, can control the fast speed heat of automobile engine by automobile ECU
The work of machine cooling system.When the temperature of cooling water reaches 60-90 DEG C, water temperature signal is passed to automobile ECU by temperature sensor,
Automobile ECU control temperature-conserving valve 3 closes non-cooled channel 32, opens simultaneously cooling duct 31, cooling duct 31 can be by High-temperature cooling
Water imports cooler 4, and cooler 4 radiates to high-temperature cooling water, water pump 5 is entered back into after being allowed to cool, after water pump 5 will be cooling
Cooling water be sent into engine 1 for cooling down engine 1.
Heated engine 1 can be used alone in the present invention, can also use simultaneously, reach with the heating structure of engine other systems
To better heat engine effect.Engine 1 is the cooling object of cooling water and the heating source of cooling water, and cooling water incubator 2 can
To keep the temperature to the high-temperature cooling water after the heating of engine 1, the volume that can store cooling water is 2-6L, cooling water incubator
2 can be used double-layer vacuum pumping INSULATION DESIGN, while coat insulation coating in the outside of cabinet or inside, allow to reach
Temperature decline is no more than 10-20 DEG C of heat insulation effect in 24 hours.Temperature-conserving valve 3 is a Three-way switch, adjustable
Engine cool circulation and heat cycles；Cooling water is introduced directly into water pump 5 by non-cooled channel 32, or passes through cooling duct 31
Water pump 5 is imported through cooler 4, water pump 5 provides power for the water circulation of 1 cooling system of engine.
When the cold start-up of engine 1 and heat engine, since 1 temperature of engine is lower, usually less than 60-70 DEG C, this time temperature
Valve 3 is started to work, and the High-temperature cooling coolant-temperature gage in cooling water incubator 2 is 70-90 DEG C, keeps the high temperature of cooling water incubator 2 cold
But water is directly entered water pump 5 by non-cooled channel 32, heats to engine 1, high-temperature cooling water is in water pump 5, engine
1, circulation in the heat cycles that cooling water incubator 2, temperature-conserving valve 3 and non-cooled channel 32 are formed, makes the quick heat engine of engine 1,
It is optimal temperature, and make component wear compared with the existing technology to reduce about 10%, while is obviously improved oil consumption and discharge.
After High-temperature cooling water temperature is more than certain temperature, temperature-conserving valve 3 works, and opens cooling duct 31, makes high-temperature cooling water
Water pump 5 is entered back into after the cooling of subcooler 4, cooling water recycles in cooling cycle.When engine 1 is shut down, cooling water is protected
Incubator 2 closes and stores high-temperature cooling water, and the cooling water temperature in cooling water incubator 2 at this time is 90 DEG C or so, under
Secondary starting or cold start-up use.
