PTC constant temperature heating element has the characteristics of constant temperature heating, the principle is that PTC constant temperature heating element after adding electricity makes resistance value enter jump zone, the surface temperature of PTC constant temperature heating element will keep constant value The temperature is only related to the Curie temperature and applied voltage of the PTC constant temperature heating element, but not to the ambient temperature.
PTC heater is a heating device designed by using the constant temperature heating characteristics of PTC constant temperature heating element. In the medium and small power heating occasions, PTC heater has many advantages over traditional heating elements, such as constant temperature heating, no open flame, high heat conversion rate, little influence by power supply voltage, long natural life, etc. The application in electric heating apparatus is more and more favored by R & D engineers. PTC constant temperature heating element can be made into a variety of shapes and different specifications, the common shape of a disc, rectangular, rectangular, ring and honeycomb porous, etc. . The combination of the PTC heating element and the metal member can form various forms of high-power PTC heater.
