Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments.The present embodiment is with the utility model
Implemented premised on technical solution, give detailed embodiment and specific operating process, but the guarantor of the utility model
Shield range is not limited to following embodiments.
Embodiment 1
As shown in Figure 1, present embodiments providing a kind of cooling system for new-energy automobile, which is included such as
Lower component：Expansion tank 10, radiator 1, compensation water pipe three-way connection 2, electric water pump 3, cooling sebific duct 8, ventilation three-way connection 6
With ventilating glue tube 11, radiator 1 connects expansion tank 10 and compensation water pipe three-way connection 2, while electric with the driving of automobile respectively
Machine 4 connects, and the other both ends of compensation water pipe three-way connection 2 connect expansion tank 10 and electric water pump 3 respectively, and electric water pump 3 is logical
Supercooling sebific duct 8 is connect with the main motor controller 9 of automobile, and main motor controller 9 connects four-in-one connection by cooling down sebific duct 8
Device, four-in-one connector are connected to controller 5 by three-way connection 6 of ventilating via cooling sebific duct 8 again, controller 5 eventually by
Cooling sebific duct 8 is linked back radiator 1, forms coolant circulation loop, at the same ventilate three-way connection 6 also by ventilating glue tube 11 with it is swollen
Swollen water tank 10 connects and composes ventilating return, and radiator 1 directly connect realization ventilation also by ventilating glue tube 11 with expansion tank 10.
It is one altogether with snorkel as shown in Fig. 2, being provided with air pressure slowing-down structure on the inner wall of snorkel in the present embodiment
The body air pressure slowing-down structure includes multiple annular projection bands, and annular projection band is spaced equal along the direction of snorkel according to the rules
It is even to be distributed in inside snorkel.And the quantity of annular projection band and the length of snorkel match and are no more than, it is specified that being spaced
The width of annular projection band.Radiator 1 is using the preferable ATS heat radiator assemblies of effect.
The course of work of this cooling system is as follows：First radiator 1 by the coolant after cooling via compensation Three-way joint for water pipe
Connector 2 is transmitted to electric water pump 3, and coolant is transmitted to main motor controller 9, four by electric water pump 3 successively by cooling down sebific duct 8
In-one controller 7, controller 5 and driving motor 4 are finally transmitted back to radiator 1 and radiate again, form the complete of coolant and dissipate
Hot loop.While coolant recycles, in order to reach better effect, need to carry out ventilation discharge to the air in coolant
To expansion tank 10, so as to improving heat radiation efficiency, it is therefore desirable to form a ventilating return, in the present embodiment, coolant flows through
After four-in-one controller 7, by the transmission for three-way connection 6 of ventilating, the gas in coolant is expelled to by ventilating glue tube 11
In expansion tank 10, ventilating return is formed, coolant is transmitted to cooling sebific duct 8 however, as the three-way connection one end, it is another
End is then ventilated, therefore easily bring coolant to ventilating glue tube 11 into, in this case can cause the feelings of gas accumulation
Condition, since 11 inner wall of ventilating glue tube is equipped with the multiple rings being evenly distributed to match with 11 length of ventilating glue tube in the present embodiment
