Description of drawings
Accompanying drawing is a theory diagram of the present utility model.
Among the figure: 1. temperature transducer, 2. speed adjusting module, 3. electric water pump, 4. power supply
Embodiment
As shown in the figure, the utility model is a kind of engine cooling fan automatic controller, and its structural feature is: contain temperature transducer (1), speed adjusting module (2), electric water pump (3), power supply (4); Temperature transducer (1) changes according to engine coolant temperature, the output voltage of control speed adjusting module (2), the rotating speed of adjusting electric water pump (3).
After engine start, motor is in cold machine operating condition, temperature transducer (1) thermistor resistance is 10K Europe, and speed adjusting module (2) output voltage is 0 volt, and electric water pump (3) does not change, engine running is after a period of time, when cooling liquid reached uniform temperature in the water jacket, temperature transducer (1) thermistor resistance began to descend speed adjusting module (2) output LOW voltage, electric water pump (3) begins to slowly run, and cooling liquid is carried out short circle from engine water jacket through thermostat; After after a while, coolant temperature continues to rise, and speed adjusting module (2) output voltage raises gradually, and electric water pump (3) rotating speed raises, and the liquid circulation amount increases, and cooling liquid is carried out major cycle from engine water jacket through thermostat; (suppose 100 ℃) when coolant temperature reaches a certain value, electric water pump (3) reaches maximum speed; If motor in the course of the work, a certain stage water temperature reduces, and electric water pump (3) rotating speed descends automatically, reduces the liquid circulation amount, guarantees that engine operation is under the optimum temperature state; Behind engine shutdown, electric water pump (3) remains in operation, and after coolant temperature reduced, electric water pump (3) was closed automatically; The utility model power supply is provided by No. 30 normalizing lines.
The utility model is not fixed for a certain model motor, but is applicable to that all engine cooling are water pump control.
The utility model also can be used for the temperature control of the engine coolant that uses 24V voltage motor or use other voltage, just input, the output voltage difference of speed adjusting module, electric water pump voltage, power difference.
The every thermistor similar to the utility model control electric water pump rotating speed is regulated the engine coolant temperature device, all within the utility model scope.
