Embodiment
The invention provides a kind of automobile engine nacelle cooling system, as shown in figure 1, the cooling system includes：Radiator
1st, water pump 2, engine cylinder-body 3, heater 4, air intake valve 5 and gearbox cooler 6, wherein gearbox cooler 6 are preferred
It is the cooler for double-clutch automatic gearbox, is cooled for being provided for the fluid of double-clutch automatic gearbox.
Wherein, the cooling liquid outlet of radiator 1 is connected by pipeline with the coolant inlet of water pump 2, the cooling of water pump 2
Liquid outlet is connected with the coolant inlet of engine cylinder-body 3, and the cooling liquid outlet of engine cylinder-body 3 is divided into three branch roads, the
One branch road 7 connects the coolant inlet of radiator 1, the second branch road 8 connection air intake valve 5, and the 3rd branch road 9 connects heater 4,
Gearbox cooler 6 is arranged on the second branch road 8 and connected with air intake valve 5, or is arranged on the 3rd branch road 9 and heater
4 series connection, the second branch road 8 and the 3rd branch road 9 are all connected with the coolant inlet of water pump 2.Wherein, it will be appreciated by those skilled in the art that
, the coolant in engine bay cooling system provided by the invention can be cooling water.
Automobile engine nacelle cooling system as described above, heater 4 or air inlet are connected on by gearbox cooler 6
On the waterway channel of valve 5, the single cooling water channel of gearbox cooler is eliminated so that flow through the recirculated water of engine itself
Flow is increased, and (40 DEG C of environment temperature ＞) contributes to vehicle thermally equilibrated by simultaneously flowing through speed change under worst hot case
The cooling water flow of the place branch road of case cooler 6 also correspondingly increased, so as to be favorably improved speed changer under worst hot case
Cooling and lubricating performance.In addition, under worst cold case (0 DEG C of environment temperature ＞), will on the basis of engine performance is not influenceed
Gearbox cooler is connected with air intake valve or heater, can also assist in being rapidly heated for gearbox fluid, is improved and is become
The performance of fast device.
Preferably, when gearbox cooler 6 is connected with heater 4, it is arranged in the front end of heater 4, keeps warm
Wind apparatus is normally opened, so that has cooling water to flow through all the time in gearbox cooler 6, and cooling water is flowing through gearbox cooler
Avoid cooling water temperature after first flowing through heater 4 by the pipeline of heater 4 again after 6 and raise and gearbox is cooled down
The cooling effect of device 6 has an impact.
In addition, the cooling liquid outlet of water pump 2 is also associated with engine oil cooler 10, the coolant of the engine oil cooler 10
Outlet is connected with the coolant inlet of water pump 2, and so as to provide cooling water for engine oil cooler, cooling is provided to engine motor oil
Cooling, ensure the performance of engine.
Further, as shown in figure 1, the cooling liquid outlet of radiator 1 is divided into two-way, expanded kettle 11 is connected to all the way
The cooling water inlet of water pump 2, another way is connected to the cooling water inlet of water pump 2 through thermostat 12, and engine cylinder-body 3 is cold
But water out is also connected with thermostat 12.
Specifically, when engine just starts, the temperature of cooling water is relatively low, and the opening temperature for being not reaching to thermostat 12 is (big
About 85~95 DEG C), now thermostat 12 is closed, only the cooling in engine cylinder-body 3 (including cylinder sleeve water jacket and cylinder cap hydroecium)
Water circulates in the presence of water pump 2, wherein there is the hole of a very little on thermostat 12, and the cooling water in engine cylinder-body 3 has very
A small part enters water pump 2 by the aperture on thermostat 12；After engine runs a period of time, the temperature of cooling water reaches
To after the opening temperature of thermostat 12, thermostat 12 is opened, and the cooling water in the exit of engine cylinder-body 3 flows through radiator 1, section temperature
Water pump 2 is flowed into after device 12.
In addition, the expansion tank 11 between radiator 1 and water pump 2, it is in parallel with thermostat 12, the steaming in radiator 1
Steam bubble in steam bubble and engine cylinder-body 3 can enter expansion tank 11 by conduit, so that gas and water is completely separated, together
When due in expansion tank 11 temperature it is relatively low, condensed into gas therein, a part becomes liquid, back flows back into water pump
2, and the gas accumulated on expansion tank liquid level then plays a part of buffering and voltage stabilizing, the pressure in cooling system is kept steady
Determine state.
