Working procedure of the present utility model is when system powers on, to enter the self check link.Check following content:
Check each sensor loop whether short circuit or short circuit: resistance approximates zero during short circuit, resistance infinity during short circuit.Report to the police when breaking down.
Whether the rotating speed of checking electric fan 1 is in normal range (NR): to electric fan 1 of short duration energising, electronic controller P calculates and judges electric fan 1 working state according to the voltage of output and the tach signal of electric fan 1 feedback, reports to the police when unusual.
Check electric heater 2 working staties: of short duration connection electric heater loop, monitoring is attached to the temperature transducer on the electric heater 2.8 or detect the electric current that flows through electric heater, judges the electric heater working state, reports to the police when unusual.
Whether detection of engine is in running order: if do not work as yet, system wait is until power-off or detect the engine operation signal.When detecting motor when in running order, electronic controller P in time enters the temperature Control work stage.
After entering temperature Control work state, cold intake temperature and coolant temperature during electronic controller P detects.When temperature is lower than setting value, do not start the driving power of electric fan 1 and the driving power of electric heater 2; When temperature reaches setting value,, electric heater 2 is applied voltage produce heat energy according to control strategy (need formulate) according to customer requirements.Electric fan 1 blows to heat energy on the bimetal temp-sensitive apparatus D of silicon oil filled fan clutch C, makes electric fan 1 with the needs rotational speed, and the heat that cooling intake temperature and motor produce keeps coolant temperature in the scope that requires.The heat stack that heat meeting that cooler B distributes and electric heating apparatus 2 produce, acting in conjunction is in the bimetal temp-sensitive apparatus D of silicon oil filled fan clutch C.
