PTC heater

PTC heater is automatic PTC ceramic heater, temperature control is a kind of special ceramic materials. Heating principle is: PTC heater power, because the room temperature resistance is small, so the starting current is larger, can make the PTC heating element quickly heating heating up, rapid increase in resistance itself into the jump area, then can pass the PTC heating element of the current is very small, make the PTC heating element surface temperature keeps constant, the temperature is only related with the PTC heating element of the Curie temperature and applied voltage, and temperature basic has nothing to do with the environment. PTC heater is in using constant temperature heating PTC thermistor temperature radiation characteristics of heating device design. In small and medium-sized power heating, constant temperature heating PTC heating appliances, the halogen-light, thermal conversion rate is high, the little affected by the power supply voltage, long natural life incomparable advantage over traditional heating elements, such as application in the electric appliance more and more get the favour of r&d engineers.
