Embodiment
Contrast accompanying drawing below, the description by to optimum embodiment is described in further detail the specific embodiment of the present invention.
As described in Fig. 1 to Fig. 3, described cooling system of hybrid vehicle, constitute by engine-cooling system and motor cooling system, described engine-cooling system comprises expansion tank 6, thermostat 3, cooling fan 7, engine radiator 2, water pump 5 and is used for being communicated with the water pipe of engine cooling water jacket and engine radiator 2; Described motor cooling system comprises motor expansion tank 10, motor and water pump 9, motor water jacket 11, electric machine controller 12 and motor radiating device 8, and motor expansion tank 10 is communicated with motor and water pump 9; Motor radiating device 8, motor water jacket 11 and motor and water pump 9 are interconnected; Electric machine controller 12 is located between motor water jacket 11 and the motor radiating device 8; Engine radiator 2 and motor radiating device 8 are arranged side by side in vehicle front deck intake grill place.
Described cooling system of hybrid vehicle is provided with independently motor cooling system, and the motor cooling system possesses independently motor radiating device structure, and the heat of motor and motor can distribute fast by radiator structure separately, perfect heat-dissipating; And engine radiator 2 and motor radiating device 8 are arranged side by side in vehicle front deck intake grill place, the cooling fan 7 that is arranged at the rear can cool off engine radiator 2 and motor radiating device 8 simultaneously, this arrangement is good heat dissipation effect not only, and compact structure, volume is little can satisfy low-cost requirement.
As shown in Figure 1, described motor radiating device comprises radiator body, on motor radiating device body, be provided with motor radiating device water intake 15 and motor radiating device water outlet 16, described engine radiator comprises the engine radiator body, is provided with engine radiator water intake 13 and engine radiator water outlet 14 on the engine radiator body.
As shown in Figure 3, for guaranteeing that motor water jacket 11 self possesses heat sinking function, effectively strengthen the heat sinking function of motor cooling system, the pipeline configuration that be exclusively used in stream cooling liquid of motor water jacket 11 for matching with motor stator, motor water jacket 11 adopts the aluminum alloy material of easily heat radiation to be made, and it can take away the motor heat by transmission of heat.
Because motor adopts the independent cooling system mode, for guaranteeing the radiating effect of motor cooling system, motor radiating device 8 is provided with and adds the pore that inject cooling liquid is used for exhaust simultaneously.
Because engine radiator 2 and motor radiating device 8 are arranged side by side in vehicle front deck intake grill place, engine radiator 2 and motor radiating device 8 shared cooling fans 7 just have good cooling effect, and the cooling fan 7 that promptly is used for engine radiator 2 and motor radiating device 8 is one; Because the heat of motor and motor radiating is different, be accurate control, reach better cooling effect, engine radiator 2 and motor radiating device 8 all adopt independently cooling fan, and the cooling fan 7 that promptly is used for engine radiator 2 and motor radiating device 8 is two.Because engine radiator 2 and motor radiating device 8 are arranged side by side, cooling fan 7 can be by cooling off engine radiator 2 and motor radiating device 8.
For strengthening cooling effect, the cooling water of being convenient in the motor expansion tank 10 enters motor and water pump 9, and the horizontal position of motor expansion tank 10 minimum level lines is higher than motor and water pump 9; Motor expansion tank 10 is provided with the cooling water inlet, is used to the cooling water of annotating; Motor and water pump 9 is controlled, and motor and water pump 9 is by relay switch control, and during starting electrical machinery water pump 9, the cooling water that motor and water pump 9 will have a certain pressure is injected in the motor water jacket 11 motor is cooled off; The high-temperature water that flows out from motor water jacket 11 is flowed through after the electric machine controller 12 preliminary coolings, flow in the motor radiating device 8, motor radiating device 8 heat diffusion area are big, and carry out heat exchange with cool air that head-on wind and cooling fan 7 drives, realization is to the cooling of high-temperature water, and the cooling liquid after the cooling is carried out next one circulation by motor and water pump 9 superchargings again.Whether the startup of motor and water pump 9 to be, by the control of relay switch, the on off state of relay by electric machine controller 12 according to the motor temperature sensor acquisition to signal deciding, when temperature is higher than predefined value, start cooling waterpump.
As shown in Figure 2, engine-cooling system mainly cools off motor, and engine-cooling system comprises expansion tank 6, thermostat 3, water pump 5, engine radiator 2, cooling fan 7 and controller, water pipe etc.One water filling hole is arranged at expansion tank 6 tops, and a water outlet is arranged at the bottom, before the system works, adds water by water filling hole, during the engine-cooling system normal working, expansion tank 6 is not used as the water storage device; When the cooling system overpressure, expansion tank 6 is used as the release device, reduces system pressure, to guarantee system's proper functioning.The expansion tank 6 of generator is identical with the structure of the expansion of motor, acts on similar.The cooling liquid that the expansion tank 6 of motor comes out directly enters water pump 5, by water pump 5 pressurizations, coolant pump to engine water jacket, is cooled off motor 1.Cooling liquid is by thermostat 3 then, also carry out big short circle by thermostat 3 by the height control cooling of coolant temperature, to be cooling liquid enter engine radiator 2 through thermostat 3 to short circle dispels the heat, cooling liquid through engine radiator 2 coolings flows into water pump 5, carries out next one circulation.Major cycle is that cooling liquid not only enters engine radiator 2 through thermostat 3, enters blower 4 simultaneously, and cooling liquid enters water pump 5 then, carries out next one circulation.
During motor 1 running, be subjected to strong heating with the contacted part of high-temperature fuel gas body, the cooling as in addition unsuitable can make motor 1 overheated, and volumetric efficiency descends, and it is undesired to burn, as detonation, pre-ignition etc.; Rotten and the scaling loss of machine oil, the friction and wear aggravation of part causes that power character, Economy, reliability and the durability of motor 1 worsens comprehensively.But if cooled off by force, the petrol engine mixed gas forms bad, the burned dilution of machine oil, and radiation loss and frictional loss increase, and the wearing and tearing aggravation of part also can make motor 1 work degenerate.Therefore, the main task of cooling system is that assurance motor 1 is worked under optimum state of temperature.
Engine-cooling system and motor cooling system are mainly considered aspect two when design: the one, and air flow system; The 2nd, coolant circulation system.In design, must accomplish to improve the heat dissipation potential in air intake coefficient and the liquid circulation.The parallel vehicle front deck intake grill place that is placed on of engine radiator 2 and motor radiating device 8 integrated types, two all is cooling system independently, does not disturb mutually, motor 1 and motor have all reached cooling preferably, guaranteed that like this car load efficient is operated between optimal zone in.
Above the present invention has been carried out exemplary description; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technological scheme carry out; or design of the present invention and technological scheme are directly applied to other occasion without improving, all within protection scope of the present invention.
