The utility model relates to the field of electric control of automobiles, and provides an electric control silicone oil fan controller. The electric control silicon oil fan controller comprises a master control central processing unit (CPU), an entire-vehicle temperature and rotating speed sensor and a fan rotating speed hall sensor, wherein an input end of the master control CPU is connected with the entire-vehicle temperature and rotating speed sensor and the fan rotating speed hall sensor respectively; and an output end of the master control CPU is connected with an electric control silicon oil fan clutch. The electric control silicon oil fan controller has a simple structure, is convenient to use, has great improvement on response speed and accuracy, and can be used on a vehicle without an entire-vehicle electronic control unit (ECU) to control the electric control silicon oil fan clutch.
Description
Technical field
The utility model relates to vehicle electric control field, a kind of specifically automatically controlled silicon-oil fan controller.
Background technique
Silicon oil filled fan clutch as medium, utilizes the full-bodied characteristic transmitting torque of silicone oil with silicone oil.Utilize the temperature of radiator back air, control the separation and the joint of fan clutch through temp-sensitive apparatus automatically.When temperature was hanged down, silicone oil did not flow, and fan clutch separates, and rotation speed of the fan slows down, and was idle running basically.When temperature was high, the viscosity of silicone oil combined fan clutch, so fan and water pump spindle rotate together, played the effect of regulating engine temperature.Traditional silicon oil filled fan clutch is that ECU is controlled with the bimetallic strip, and speed of response is slow, and precision is low, and must rely on car load car running computer (ECU) to control.
Summary of the invention
The purpose of the utility model is exactly in order to overcome the deficiency of above-mentioned existing technology; And a kind of automatically controlled silicon-oil fan controller is provided; It is simple in structure; Easy to use, on speed of response and precision, improve a lot, and can on the vehicle that does not have car load ECU, make and be used for controlling automatically controlled silicon oil filled fan clutch.
The purpose of the utility model realizes through following technical measures: a kind of automatically controlled silicon-oil fan controller; Temperature and the speed probe, the rotation speed of the fan Hall transducer that comprise master cpu, car load; The input end of said master cpu links to each other with the rotation speed of the fan Hall transducer with the temperature and the speed probe of car load respectively, and the output terminal of master cpu links to each other with automatically controlled silicon oil filled fan clutch.
In technique scheme; Said master cpu adopts the LPC236X chip; 18,19 pin of LPC236X chip connect the 24V switching power circuit, and 14,15,16,17 pin of LPC236X chip connect the temperature of car load and the signal output part of speed probe, the signal output part of 11,12,13 pin wind-receiving fan rotating speed Hall transducers of LPC236X chip; 9,10 pin of LPC236X chip are that data output end connects automatically controlled silicon oil filled fan clutch, and 1～8 pin of LPC236X chip connects data storage cell.
The beneficial effect of the utility model is: adopt main control chip CPU to control, on speed of response and precision, improve a lot, and can on the vehicle that does not have car load ECU, make and be used for controlling automatically controlled silicon oil filled fan clutch.
Description of drawings
Fig. 1 is the circuit theory diagrams of the automatically controlled silicon-oil fan controller of the utility model.
Fig. 2 is the electrical connection diagram of the automatically controlled silicon-oil fan controller of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe.
Like Fig. 1, shown in 2; Present embodiment provides a kind of automatically controlled silicon-oil fan controller; Temperature and the speed probe, the rotation speed of the fan Hall transducer that comprise master cpu, car load; The input end of said master cpu links to each other with the rotation speed of the fan Hall transducer with the temperature and the speed probe of car load respectively, and the output terminal of master cpu links to each other with automatically controlled silicon oil filled fan clutch.
In last embodiment; Master cpu adopts the LPC236X chip; 18,19 pin of LPC236X chip connect the 24V switching power circuit; 14,15,16,17 pin of LPC236X chip connect the temperature of car load and the signal output part of speed probe; The signal output part of 11,12,13 pin wind-receiving fan rotating speed Hall transducers of LPC236X chip, 9,10 pin of LPC236X chip be data output end to connect the data output unit be automatically controlled silicon oil filled fan clutch, 1～8 pin of LPC236X chip connects data storage cell.
The automatically controlled silicon-oil fan controller that present embodiment provides is supplied power by the 24V power supply; The computer that is connected by the outside writes and revises the control program in the chip; The temperature of Hall transducer and car load, speed probe passes to automatically controlled silicon-oil fan controller with signal, and by the master cpu analytical calculation; Final output pwm signal is given automatically controlled silicon oil filled fan clutch, and its rotating speed is controlled.When the temperature of motor raise, the speed of silicon-oil fan raise, and increased the air quantity through radiator; When the temperature of motor reduced, the speed of silicon-oil fan reduced, and reduced the air quantity through radiator.
Under the normal condition, the rotating speed of the automatic solenoidoperated cluthes of automatically controlled silicon-oil fan controller, micro computer moves automatically; When accident takes place (sensor failure, wire harness short circuit, wire harness open circuit etc.), controller automatically switches to unexpected pattern, and the PWM value that output is maximum guarantees that fan can normally dispel the heat to automobile, the minimizing unnecessary loss.
