The operation principle and process of the present invention
Temperature sensor 5 is arranged near drive module 4, and the temperature signal S1 detected by it is arrived by wire transmission
CPU main control modules 6, CPU main control modules 6 are handled temperature signal, calculate temperature value.
The temperature that temperature sensor 5 detects is higher, and CPU main control modules 6 are by wire transmission driving current I1 to partly leading
The average current value of body cooling piece 2 is bigger, and the refrigeration intensity of semiconductor chilling plate 2 is bigger.
CPU main control modules 6 pass through wire transmission driving current I3 and driving current I4 to two fan 8, current value respectively
Bigger, the rotating speed of fan 8 is faster, and the radiating rate of condenser pipe 10 and fin 9 is faster.What temperature sensor 5 detected
Temperature is higher, and driving current I3 and driving current I4 value are bigger, and the rotating speed of fan 8 is higher.
CPU main control modules 6 are by wire transmission driving current I2 to water pump 13, and driving current I2 value is bigger, water pump 13
Rotating speed it is faster, the water inlet of water pump 13 and to go out water speed faster.The temperature that temperature sensor 5 detects is higher, driving electricity
Stream I2 value is bigger, and the rotating speed of water pump 13 is higher.
The specific heat capacity of water in water cooling system is larger, and under the conditions of the coolant of same volume, water can absorb more
Heat, but because water specific heat capacity is larger so that water cooling system thermal inertia coefficient is larger, and radiating efficiency is relatively low, especially water
Cooling system can not produce the absorption calorie source lower than environment temperature.Semiconductor chilling plate 2 in the integrated system produces low
The face of temperature, the absorption calorie source lower than environment temperature can be produced, and semiconductor chilling plate 2 produces the actual temp in low temperature face
It can be controlled by CPU main control modules 6, it is timely so as to realize with reference to the advantages of semiconductor chilling plate 2 and water cooling system
The efficient purpose for reducing electric vehicle control system operating temperature, building good running environment.
