Background technology
The orthodox car engine power is big, and is bigger to the demand of radiator area, and the motor that the hybrid vehicle utilization increases compensates the reserve horsepower of driving engine, and the hybrid power system engine power can be reduced.Therefore, the hybrid power system driving engine reduces the radiator heat-dissipation area requirements.Consider the demand of the newly-increased electric system of hybrid power system,, but need increase an electric water pump, be used for providing circulation power to cooling water expansion tank to electric system with the shared radiator of driving engine to cooling.But for hybrid vehicle with two cover electric systems, the parts that electric system need cool off are more, comprise drive motor, drive motor controller, ISG motor and ISG electric machine controller, and arrangement space is limited in the car, if the size of electric water pump is too big, bring very big difficulty to arranging in the crowded cabin, hybrid power engine cabin.Therefore, consider that car load should satisfy the electric system cooling requirement, satisfy the car load layout requirement again, be difficult to use the bigger water pump of power simultaneously two cover electric systems to be cooled off.
For this reason, people have carried out long-term exploration, have proposed various solutions.For example, Chinese patent literature discloses a kind of hybrid-power electric vehicle motor cooling mechanism [application number: CN200620058939.4], mainly comprise fluid-cooled electrical machine, the motor radiating device, liquid pump, electric fan, temperature control unit and temperature-sensing element, fluid-cooled electrical machine, liquid pump is connected by the circulation fluid pipe respectively with the motor radiating device, the input end of temperature control unit is connected with temperature-sensing element on being arranged at fluid-cooled electrical machine, two mouths of temperature control unit are connected with electric fan with liquid pump respectively, the parallel installation of motor radiating device 1 and place the upstream of cooling-air flow with engine radiator, electric fan and the parallel installation of motor radiating device and place the upstream of cooling-air flow.Owing to when the combination drive pattern, can make full use of engine blower and in to the engine radiator radiating and cooling, the motor radiating device be carried out radiating and cooling, reach energy-conservation and prolong the motor radiating device electric fan purpose in service life.
Yet it is reasonable inadequately that such scheme still exists in the prior art design, is difficult to layout, and radiating effect is difficult to satisfy and uses technical matterss such as required.
Summary of the invention
The purpose of this utility model is at the problems referred to above, and a kind of compact conformation is provided, and can effectively utilize interior space, is easy to layout, the series hybrid electric vehicle cooling mechanism of good heat dissipation effect.
