Principle is the PTC heater is charged with self-heating temperature rise so that the resistance value rises into the jump zone, the PTC heater surface temperature will remain constant value, the temperature is only with the PTC heater Curie temperature and the applied voltage, and with the ambient temperature basically has nothing to do. Even in the case of abnormal operation, the input power can be reduced to a very low level due to the regulation of the PTC element itself and still be free of surprises.
Role:
1, constant temperature heating PTC thermistor with constant temperature heating characteristics, the principle is that the PTC thermistor heating self-heating heating resistance into the jump zone, constant temperature heating PTC thermistor surface temperature will remain constant value, the temperature is only related to the Curie temperature of the PTC thermistor and the applied voltage, and with the ambient temperature is basically irrelevant. The temperature is only related to the Curie temperature of the PTC thermistor and the applied voltage, and the ambient temperature.
2, PTC heating element is the use of constant temperature heating PTC thermistor constant temperature heating characteristics of the design of heating elements. In the small and medium power heating occasions, PTC heating element has a constant temperature heating, no open flame, high heat conversion rate, by the power supply voltage is very small, the natural life of the traditional heating element can not be compared to the advantages of the application of electric heating appliances in the R & D engineers more and more favored.
3, constant temperature heating PTC thermistor can be made into a variety of shape structure and different specifications, common round piece shape, rectangle, rectangle, ring, and honeycomb porous and so on. The above PTC heating element and metal components can be combined to form a variety of forms of high-power PTC heating elements.
