PTC heater energized, because the room temperature resistance is small, so the starting current is larger, can make the PTC heater very quickly heat up, resulting in its own resistance value increases rapidly into the leap zone, when the PTC heater can pass through the current is very small, so that the surface temperature of the PTC heater always maintain a constant value, the temperature only with the Curie temperature of the PTC heater and the applied parameters. The current is very small, so that the surface temperature of the PTC heater is always maintained at a constant value, the temperature is only related to the Curie temperature of the PTC heater and the applied voltage, but basically has nothing to do with the ambient temperature.PTC heater is a heating device designed to utilize the thermostatic heating characteristics of the PTC thermistor.
In the small and medium power heating occasions, PTC heaters have a constant temperature heating, no open flame, high thermal conversion rate, by the power supply voltage is very small, long natural life and other traditional heating elements can not be compared to the advantages of the application of electric appliances in the R & D engineers more and more favored.
