The technological development and design of various aspects have carried out a large amount of input.Cooling system as electric motor coach key technology it is a kind of by
More and more attention are arrived.In electric motor coach operational process, driving motor, electric machine controller Centralized Controller（It is three-in-one
With four-in-one etc.）A large amount of heat is will produce with stand-by motor controller etc..Heat and the heat product that these critical components generate
It is poly- unfavorable for the safety of the runnability of component itself, service life and surrounding other component.In addition, the driving of electric motor coach and each
Class energy consumption component directly influences the course continuation mileage of electric motor coach all from vehicle mounted dynamic battery, the energy consumption of each base part.
Therefore, an energy-efficient cooling system is most important for electric motor coach.
Electric motor coach cooling system includes mainly radiator（Including radiator fan）, expansion tank（It installs on demand）, it is cold
But liquid pump, wait for thermal component and connecting pipe.When cooling system works, coolant pump will be by the sub-cooled of radiator cooling
Liquid, which is sent to each, needs cooling component, and coolant liquid and temperature after the heat exchange of each heat source are higher, need to enter radiator heat-dissipation pipeline
It is cooled down.High temperature coolant inside radiator pipeline transfers heat to metallic conduit and radiating fin etc..Outside radiator
Low ambient temperature air is pumped to radiator heat-dissipation face and carries out heat exchange by portion's radiator fan, and heat is taken away.It is cooled down through radiator
Coolant temperature afterwards is relatively low, is sent again to each high-temperature component and is exchanged heat through coolant pump, completes cycle.
Core component of the radiator as electric motor coach cooling system, heat dissipation performance directly affect the cooling of cooling system
Effect.For radiator, many exploitation designers have carried out a large amount of research to the control of radiator.Such as：To radiator fan reality
When control, wind speed etc. is adjusted according to cooling system heat situation.But on the one hand this kind of design and work increase answering for control
On the other hand miscellaneous degree can not equally solve the problems, such as that system energy consumption is more.Also research and designer, by optimizing radiator
Radiator structure, to improve heat transfer effect.But most designer does not account for practical cloth of the radiator on electric motor coach
Set problem.On most electric motor coaches, heat radiator assembly is arranged in water tank cabin.Radiator heat-dissipation face and vehicle body parallel,
Radiator fan blows air to radiating surface after radiator heat exchanger.Vehicle in the process of moving, under radiator arrangement space
Portion is low-pressure area（Air pressure）, and radiator space is higher-pressure region（Air pressure）.Radiator fan needs that this part is overcome to press when working first
Difference increases the energy consumption of entire cooling system, affects the course continuation mileage of pure electric coach, while also not meeting energy-efficient reason
It reads.In addition, the air quality that radiator fan is pumped to radiator can not ensure, vehicle may make part mould in the process of moving
Material film or other rubbish enter fan or radiator, and that hinders fan blows cooling air, influence heat dissipation effect, or even damage
Radiator fan.
