Description
Technical field
The invention belongs to automobile cooling system field, specifically refer to a kind of include that the electromotor of double expansion tank is cold
But system.
Background technology
The oil consumption of electromotor is promulgated more and more harsh standard by national governments, such as specifies in the year two thousand twenty requirement
Automobile main frame maker persistently reduces oil consumption to 5.0L/100km；Fuel-economizing has become as the development trend of world car,
And a most important technology is exactly the supercharging miniaturization+Technology of Hybrid Electric Vehicle of electromotor in fuel-saving measures.
In response to the regulation of local government, it is necessary to find a kind of Engine Matching system more innovated
Become this target.Because on the premise of not losing dynamic property, want oil consumption to decline on the basis of at present
30% is substantially an impossible mission.It is proposed that face uses hybrid power system on the engine
The supercharging of+electronics, by weak mixed and engine booster miniaturization, reduces the requirement of oil consumption with this.By
Extremely complex in whole system coupling, corresponding car load design of Cooling System also tends to complexity.

The continuous popularization of oil tech, amount of parts integrated on electromotor gradually increases, as charge air cooler, BSG,
Electron pressurizing unit etc., these new integrated parts, need also exist for cooling down, but, its institute
Chilling temperature, flow and the control logical AND engine cylinder-body, the cylinder cap that need are completely different；Therefore,
Traditional cooling controls loop can not meet the application of new technique.
It addition, traditional mechanical type thermostat response is slowly, opens, close the water temperature by electromotor
Determine, be unfavorable for the warming-up of electromotor and the quick cooling of water temperature.
Prior art proposes, and charge air cooler, BSG and Electron pressurizing unit are used air-cooled technology, but air-cooled
High to space requirement, whole enging cabin is disposed with high requirement, arranges that difficulty is big, heat evil meter
Calculating complexity, thermal balance risk is big, can be only achieved ideal effect it is generally required to be iteratively improved, additionally car load
Use environment is changeable so that air cooling system is difficult to meet the demand of the multiple each operating mode of use environment.
To this end, existing engine-cooling system is proposed to improve by applicant, the early stage being specifically shown in applicant is special
Profit, CN 105134359A, a kind of engine-cooling system using delay circulation stream；CN

In technology, applicant by existing engine cooling and circulating system by improve stream, be improved to high temperature
Blood circulation and cold cycle system, and postpone blood circulation, comprehensively improve electromotor and respectively need
Want the cooling effect of cooling-part, and such improvement technical scheme, compared with technical scheme compare,
Blood circulation cooling effectiveness whole to electromotor improves a lot；But at further research process
In, it has been found that the different coolings order between each parts that electromotor and whole needs cool down,
The most different cooling flowing paths, the raising to the cooling effectiveness of whole cooling system is different, and this
Difference does not have comparability, the i.e. little improvement to cooling flowing path and is respectively provided with different cooling effects.

Cold cycle cooling system dissipates for the cooling to BSG, turbocharger and charge air cooler, low temperature
In hot device, coolant is by being divided into two-way to flow separately through the string of BSG and turbocharger after electronic water pump sucking-off
Connection branch road and charge air cooler branch road, the coolant after temperature raises merges in entrance low-temperature radiator.It addition,
Coolant in expansion tank sucks electronic water pump by the water pipe before electronic water pump, prevents electronics
Before water pump, hypotony produces cavitation erosion, meanwhile, the cooling of the mixing bubble in low-temperature radiator upper water box
Liquid is because the pressure differential of expansion tank and low-temperature radiator upper water box is by second on second exhaust pipeline
Choke valve 019 enters the second expansion tank.
Cold cycle cooling system has single low-temperature radiator, meets charge air cooler inflow temperature and controls
The cooling requirement of less than 55 degrees Celsius；The electronic water pump that cold cycle coolant power resources ECU control,
Meet low engine speeds, high load capacity or the electromotor BSG when carrying out thermal starting by BSG front end belt
Radiating requirements with charge air cooler；The electronic water pump that cold cycle coolant power resources ECU control is full
After foot engine cutoff, the delayed quench demand of turbocharger.
The high temperature circulation cooling system of the present invention runs alone with cold cycle cooling system, and both are the most not
Intervene.
The above is only the description of the preferred embodiment of the present invention, it is noted that due to literal table
The finiteness reached, and objectively there is unlimited concrete structure, for the common skill of the art
For art personnel, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications,
These improvements and modifications also should be regarded as protection scope of the present invention.
