Detailed description of the invention
As shown in Figure 1, the utility model comprises MCU2 control water pump 1 and works, cooled by the first radiator 8 after refrigerant fluid acts on drive motor 3 and electrical generator 4, on MCU2, drive motor 3, electrical generator 4, equal built-in temperature sensor 6 carries out temperature sensing, collecting temperature is fed back to entire car controller by temperature sensor 6, and vehicle control unit controls first radiator 8 works; Second radiator 9 acts on the refrigerant fluid of driving engine 12, built-in motor temperature sensor 13 on driving engine 12, and engine temperature sensing unit 13 is by the temperature feedback that collects to engine electric-controlled unit, and engine electric-controlled unit controls the second radiator 9 and works.
MCU2 comprises drive motor controller and engine controller.First radiator 8 is provided with the first fan 10; Second radiator 9 is provided with the second fan 11.Be provided with DCDC5 in cooling system and connect the first radiator 8 and MCU2 respectively.Expansion tank 7 connects water pump 1 and works.Second radiator 9 acts on overflow kettle 14, first radiator simultaneously and acts on DCDC5 simultaneously.
Specifically as shown in Figure 1, driving engine 12 optimum working temperature is generally at 90 DEG C ~ 100 DEG C, and drive motor 3, electrical generator 4, MCU2 and DCDC5 optimum working temperature are generally at 60 DEG C ~ 70 DEG C.Adjustable radiation device system divides engine radiator (the second radiator 9 region) and motor adjustable radiation device (the first radiator 8 region) two parts composition.This range-extended electric car cooling system is divided into two sub-cooling circulation: engine cooling circulation, electric system cooling circulation.
The mechanical water pump that engine cooling circulating cooling liquid is carried by driving engine 12 drives, and driving engine 12 outlet temperature is about 90 DEG C ~ 100 DEG C, after the second radiator 9 in adjustable radiation device system dispels the heat, returns driving engine 12.Refrigerant fluid unnecessary in cooling system work is regulated by expansion tank 14.Temperature in circulation controls to be completed by engine electric-controlled unit.
