Because operating voltage is low and rotating speed is slow, wind-force is small, when calculate built-in temperature gradually rise (fully loaded work), thermistor RT internal resistance
It is gradually reduced, the voltage of B points is also raised, therefore the output voltage of C points is also and then raised, fan rotating speed because of operating voltage rise
Quickening, wind increases.After built-in temperature declines, thermistor RT internal resistances gradually increase, and B points voltage declines, the output electricity of C points
Pressure also reduce, fan because operating voltage is low and rotating speed is slack-off, wind-force is small.When B point voltages (temperature) are raised to a certain extent, U1
In-phase end voltage is higher than end of oppisite phase reference voltage, and U1 output high level returns to B points through D1, R13 all the way, U1 is exported all the time
High level (namely self-locking)；Another road is output to thermal-shutdown circuit through D2, realizes overheat protector function.
