R1, potentiometer RP1 form bridge for measuring temperature.Operational amplifier IC2 amplifies as buffering isolation as difference amplifier, IC1
Device, IC3 is as square-wave generator (i.e. triangular wave formation circuit), and IC4 is as pulse width modulator.Connect computer USB
After interface J1, the 5V DC voltage of USB interface output, as supply voltage, provides running voltage, brilliant lock for bridge for measuring temperature
Pipe Q1, as execution unit, controls the work of fan M.The square-wave oscillator being made up of IC3 and its peripheral cell,
The square-wave signal produced, from the 4 foot outputs of IC3, after resistor R6 and capacitor C1 is processed into triangular signal,
Add from 1 foot of IC4 again.The output signal of bridge for measuring temperature, after IC2 amplifies, after the 4 foot outputs of IC2, adds
3 feet of IC4.The 4 foot output Square wave pulses voltages of IC4, its pulse width is modulated by IC2 output voltage, is worked as IC4
3 foot voltages less than 1 foot voltage time, the 4 feet output high level of IC4, make IGCT Q1 turn on, fan M is energized work,
Light emitting diode D1 lights simultaneously, and instruction fan is in radiating state, when the 1 foot voltage of IC4 is higher than 3 foot voltage,
The 14 foot output low levels of IC1, make Q1 end, and fan M does not works, and D1 extinguishes.This radiator fan uses cycle switch
Control mode, in the switch fixed cycle, the time ratio switched by control controls temperature, when calculating built-in temperature higher than control
During value processed, the pulse width of the 4th foot output square wave of IC3 reduces, and fan M electrical working time increases therewith, power-off
Time diminish, make temperature decline；Otherwise, then work process is contrary, and the change of open and close time ratio is again a gradual change
Process, therefore temperature-controlled precision is higher, and temperature fluctuation is little.
