The invention discloses an electronic thermoregulator of an automobile air conditioner, which comprises a DC power supply, a start switch, a thermistor, a first comparator, a second comparator, an electronic switch integrated circuit, a first resistor, a second resistor, a third resistor, a fourth resistor, a fifth resistor, a sixth resistor, a seventh resistor, an eighth resistor, a ninth resistor, a capacitor, a sliding rheostat, a first light emitting diode, a second light emitting diode, a first terminal and a second terminal. When the electronic thermoregulator is used, the first terminal and the second terminal are respectively connected with the two ends of a clutch of the automobile air conditioner, and if the thermistor detects the temperature is lower (or higher) than a set value, the circuit of the automobile air conditioner is turned on by the cooperation of the first comparator, the second comparator and the electronic switch integrated circuit to drive the air conditioner to work, and the air conditioner stops working after reaching the set high temperature (or low temperature). The electronic thermoregulator disclosed by the invention has the advantages of simple structure, low cost, accuracy in control and convenience for generalization.
