Electronic device heat dissipation automatic control circuit

The figure shows the automatic control circuit diagram of the electronic device. This circuit consists of 555 circuits. NE555 is connected to work as Schmidt. The thermistor RT is a temperature sensor that is connected in series with the adjustment potentiometer RP and connects their voltage dividers to the signal input of the Schmitt circuit. A control relay K is connected between the output of the Schmitt circuit and the power source, and a small ventilation fan that is ventilated and ventilated is controlled by the relay. When the temperature is too high, the control circuit will start the ventilation fan to achieve ventilation and cooling.
