Background technique
Cooling system is the important component part of motor car engine, is to work under optimum state of temperature for the assurance motor.
At present, motor car engine generally adopts the cooling system of traditional enclosed pump circulation, its structural type as shown in Figure 4, by constituent and air cooling system two-part, formed, utilization is contained in the circulating water pump 10 in runner, to engine pressure, supplies water, and cooling liquid circulates in engine water jacket 1, the water outlet of engine water jacket 1 is inflow radiator 3 after thermostat 7, then flow back into the intake pipe of circulating water pump 10.Radiator 3 heat that cooling liquid is entrained spills into atmosphere to reduce coolant temperature, and radiation fan 9 is used for increasing the air velocity of the radiator core of flowing through, to improve the radiating efficiency of radiator 3.Radiation fan 9 and circulating water pump 10 are driven by belt pulley 11 and driving belt 12 by bent axle 8, and are by fixing speed ratio running.
In order to regulate the coolant rate of the radiator of flowing through, thermostat 7 is set in water channel near the cylinder head water outlet.When coolant temperature, during lower than the low temperature setting value, thermostat turn-offs, the cooling liquid radiator of not flowing through, and pump operation is only circulated cooling liquid in water jacket, usually is referred to as " short circle "; And when temperature during higher than the high temperature setting value, thermostat is opened, the running of water pump makes the cooling liquid radiator of flowing through, and forms circulation between radiator and water jacket, usually is referred to as major cycle; When temperature is between low temperature setting value and high temperature setting value, a part of cooling liquid is carried out major cycle, and another part cooling liquid is carried out short circle.Fan power loss and heat loss when reducing low speed, fan drive mechanism often adopts silicon oil clutch, reduces rotation speed of the fan when the high speed small load condition, reduces air quantity.
In the system architecture of this large and small circulation, cooling capacity is only to change along with rotating speed, and motor actual conditions and cooling system are difficult to accomplish coupling, causes preheating slowly and the phenomenon such as overheated during large load.Main manifestations is:

2) water temperature over-high when water pump, the large load of fan power deficiency, particularly low speed during the large load of motor, lubricant film is destroyed, and Part Thermal Deformation increases, mechanical strength and stiffness degradation, shorten working life.
At present, the heat dissipation potential of cooling system is normally according in motor operating mode commonly used and the higher situation of temperature, can guarantee coolingly and design reliably, this makes when service condition changes, need to be not in tune from the fall apart heat dissipation potential of the heat walked and cooling system of cooling system.Especially fan and water pump in traditional cooling system are all directly controlled by motor, and fixing control mode has greatly limited the adaptability of motor under different operating modes.Its basic reason is that the rotating speed of water pump, fan and the speed ratio of speed of crankshaft are constant, and that the heat radiation of motor requires is not only relevant with rotating speed, and affect larger is load, and obvious traditional system form and control mode can't meet this requirement.
