Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.
According to the utility model embodiment, provide mimic channel by Automobile air conditioner switch and coolant temperature switch control condenser fan.As shown in Figure 1, present embodiment comprises direct supply, ignition switch 2, air-conditioning switch 3, pressure switch 4, temperature switch 5,7,105 ℃ of switches 8 of 6,95 ℃ of switches of normally opened relay, resistance 9, DC fan 10 and bulb 11.Here, direct supply is an accumulator 1.
Wherein, the minus earth of above-mentioned direct supply; The positive pole of direct supply, and behind the solenoid of ignition switch 2, air-conditioning switch 3, pressure switch 4, temperature switch 5 and normally opened relay 6 ground connection, ground connection behind the switch contact of normally opened relay 6 and bulb 11, ground connection behind the motor of 95 ℃ of switches 7, resistance 9 and DC fan 10, and behind the motor of 105 ℃ of switches 8 and DC fan 10 ground connection; The common port of the switch contact of described normally opened relay 6 and bulb 11 is connected with the common port of 95 ℃ of switches 7 and resistance 9.
In the above-described embodiments, the condition of pressure switch 4, temperature switch 5 difference simulated pressures and temperature, when pressure, when temperature satisfies condition, switch is closed, on the contrary then switch disconnects; 95 ℃ of switch 7 simulated engine water temperatures should be closed greater than 95 ℃ the time, should disconnect during less than 95 ℃; 105 ℃ of switch 8 simulated engine water temperatures should be closed greater than 105 ℃ the time, should disconnect during less than 105 ℃; The duty of bulb 11 simulation compressor of air conditioner electromagnetic clutchs, bulb 11 bright expression electromagnetic clutch adhesives, compressor operating, on the contrary then compressor is not worked.DC fan 10 simulation condenser fan are because the dividing potential drop effect of resistance 9 forms low or first gear when DC fan 10 and resistance 9 tandem workings.
The mimic channel that passes through Automobile air conditioner switch and coolant temperature switch control condenser fan of the foregoing description, principle of work and control function are as follows:
