What are the principle and function of PTC heater?
The PTC heater is a heating device designed to use the thermostatic heating characteristics of PTC thermistors. Characteristic design of heating devices. In small and medium power heating occasions, PTC heaters have constant temperature heating, no open flame, high thermal conversion rate, by the power supply voltage is very small, natural long life and other traditional heating elements can not be compared to the advantages of the application of electric heating apparatus more and more favored by the R & D engineers. Constant temperature heating PTC thermistor can be made into a variety of shape structure and different specifications, the common ones are round piece-shaped, rectangular, rectangular, circular, and honeycomb porous shape. The above PTC heating elements and metal components can be combined to form various forms of high-power PTC heaters.
1. Constant temperature heating PTC thermistor has a constant temperature heating characteristics, the principle is that the PTC thermistor heating up the resistance value into the jump zone, constant temperature heating PTC thermistor surface temperature will remain constant value, the temperature is only related to the PTC thermistor Curie temperature and applied voltage, and the ambient temperature is basically irrelevant.
2. PTC heating element is the use of constant temperature heating PTC thermistor thermostatic heating characteristics of the design of the heating element pieces. In small and medium power heating occasions, PTC heating element has constant temperature heating, no open flame, high thermal conversion rate, by the power supply voltage is very small, natural long life and other advantages of traditional heating elements can not be compared, the application of electric heating apparatus is increasingly favored by the R & D engineers.
