The temperature sensor of the air conditioner of the car air conditioner is to detect the temperature of the air outlet, which is the actual temperature blown into the cabin, and then the controller uses the input used in conjunction with this temperature detection, such as temperature increase and decrease. The conduction method is changed from the conventional pure NTC thermistor epoxy package heat transfer to a uniform temperature through the thermally conductive copper sheet, which is more stable. At the same time, the NTC thermistor is wrapped, which can effectively prevent corrosion of dust, acid, alkali, salt, Extend the service life; the integrated design of the car air conditioner temperature sensor can be easily installed in one step.
