Abstract
The invention discloses an automatic control method of an engine cooling fan. The structure of the engine cooling fan is structurally characterized by comprising a temperature sensor (1), a speed regulation module (2), an electric fan (3) and a power supply (4). In accordance with temperature change of engine coolant, the temperature sensor (1) controls the output voltage of the speed regulation module (2) and adjusts the rotating speed of the electric fan (3).Therefore, the rotating speed of the engine cooling fan can be automatically controlled, the temperature of the engine coolant can be adjusted, and the temperature of the engine coolant can be held within a preset temperature range. The method can effectively save fuels, reduce emission pollutants and better exert advantage of automobile.

Among the figure: 1. temperature transducer, 2. speed adjusting module, 3. electric fan, 4. power supply
Embodiment
As shown in the figure, the present invention is a kind of engine cooling fan autocontrol method, and its structural feature is: contain temperature transducer (1), speed adjusting module (2), electric fan (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 fan (3).
After engine start, motor is in cold machine operating condition, and temperature transducer (1) thermistor resistance is 10K Europe, and speed adjusting module (2) output voltage is 0 volt, and electric fan (3) does not change, cooling liquid through the short circle road through the circulation; Engine running is after a period of time, when cooling liquid reaches uniform temperature in the water jacket, cooling liquid from engine water jacket through thermostat major cycle interface to cooling water tank, carry out major cycle through recycle pump, after after a while, coolant temperature rises, temperature transducer (1) thermistor resistance begins to descend, speed adjusting module (2) output LOW voltage, electric fan (3) beginning tick-over is dispelled the heat to water tank; If coolant temperature continues to rise, speed adjusting module (2) output voltage raises gradually, and electric fan (3) rotating speed raises, and water tank is dispelled the heat, and (supposes 100 ℃) when coolant temperature reaches a certain value, and electric fan (3) reaches maximum speed; If motor in the course of the work, a certain stage water temperature reduces, and electric fan (3) rotating speed descends automatically, reduces engine radiating, guarantees that engine operation is under the optimum temperature state.Behind engine shutdown, electric fan (3) remains in operation, and after coolant temperature reduced, electric fan (3) was closed automatically.Power supply of the present invention is provided by No. 30 normalizing lines.
The present invention is not fixed for a certain model motor, but is applicable to that all engine cooling are rotation speed of the fan control.
The present invention also is used for the 24V motor or uses the temperature of the engine coolant of other voltage to control automatically.Be input, the output voltage difference of speed adjusting module, power of motor is different with the resistance of fan size and thermistor.
