Machine controller, DCDC, charger etc..Existing new-energy automobile is mainly cold using each part is connected in series to cooling system progress
But, this mode is arranged simply, and each cooling element flow is identical.But simple just series connection can make to work between all parts and not assist
Adjust, some components need to cool down, and component need to heat again.Therefore this is a paradox.Due to each cooling element
Working time, traffic requirement it is inconsistent, when only subelement works, concatenated cooling system still can be flowed through and entirely be followed
Loop back path, this just needs to match bigger water pump, and simply series connection will cause all parts and cannot work at the same time best
Working condition, there is very big drawback, consume more electric energy, cause the very big wasting of resources.
Summary of the invention
The purpose of this utility model is that a kind of pure electric vehicle cooling system loop structure is proposed, by increasing a threeway
Solenoid valve separates the cooling of charger as branch, according to working condition respectively to charger and driving motor and its phase
Matched electrical equipment is cooled down, the service efficiency of lifting system.Reduce cost.
To achieve the goals above, the technical solution of the utility model is: a kind of pure electric vehicle cooling system loop structure,
Including radiator, water is back to scattered by an electronic water pump after the heat dissipation object that radiator outlet extraction flows to pure electric vehicle
The water return outlet of hot device, the heat dissipation object include DCDC supply convertor, electric machine controller, driving motor and charger,
In, the delivery outlet of the electronic water pump is first connected to the input port of a three-way magnetic valve, two outputs of three-way magnetic valve
Mouth is respectively the first delivery outlet and the second delivery outlet, the first delivery outlet and DCDC supply convertor, motor control of three-way magnetic valve
The first entrance of a threeway, the second delivery outlet and charger string of three-way magnetic valve are connected to after device processed, driving motor series connection
The second entrance of the threeway is then connected to after even, the delivery outlet of the threeway is connected to the water return outlet of radiator, a cooling
Dispensing controller connects the three-way magnetic valve and electronic water pump.
Scheme is further: being respectively set in the DCDC supply convertor, electric machine controller, driving motor and charger
There is temperature sensor, temperature sensor signal is connected to the cooling dispensing controller.
Scheme is further: on the shell of the DCDC supply convertor, electric machine controller, driving motor and charger
It is respectively arranged with temperature sensing hole, the temperature sensor is enclosed on a screw, and screw screws in temperature sensing hole will be described
Temperature sensor is fixed in temperature sensing hole.
Scheme is further: the disengaging cooling of the DCDC supply convertor, electric machine controller, driving motor and charger
Waterpipe jointing is the fast insert-pull cooling water connector of polytetrafluoro material.
The beneficial effects of the utility model are: by increasing a three-way magnetic valve using the cooling of charger as branch point
It separates out and, can flexibly control cooling requirement.Since when electric vehicle charges, other systems do not work, only charger work
Make, solenoid valve opens charger channel, closes motor channel；In vehicle travel process, when due to braking recovery system operation
Charger also assists in work, and solenoid valve needs to open duplex channel and cools down to whole system.Cooling system can be improved in this way
The radiating efficiency of system, reduces the part of cooling system, and the service efficiency of lifting system reduces cost.
The utility model is described in detail with reference to the accompanying drawings and examples.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
A kind of pure electric vehicle cooling system loop structure, as shown in Figure 1, the structure includes radiator 1, an electronic water
Water is back to the water return outlet of radiator by pump 2 after the heat dissipation object that radiator outlet extraction flows to pure electric vehicle, described to dissipate
Heat target includes DCDC supply convertor 3, electric machine controller 4, driving motor 5 and charger 6, wherein the electronic water pump
Delivery outlet be first connected to the input port of a three-way magnetic valve 7, two delivery outlets of three-way magnetic valve are respectively first defeated
Outlet and the second delivery outlet, the first delivery outlet and DCDC supply convertor, electric machine controller, driving motor string of three-way magnetic valve
It is connected to the first entrance of a threeway 8 after connection, is then connected to institute after the second delivery outlet and the charger series winding of three-way magnetic valve
The second entrance of three-way interface is stated, the delivery outlet of the three-way interface is connected to the water return outlet of radiator, a cooling distribution control
Device 9 processed connects the three-way magnetic valve and electronic water pump.
Wherein: being respectively arranged with temperature in the DCDC supply convertor, electric machine controller, driving motor and charger and pass
