The original PTC heater of household appliance PTC heater has a small heat capacity, so it can blow out hot air as soon as it is energized. The PTC calorific value changes with the ambient temperature. When the ambient temperature is low, the calorific value increases accordingly; when the ambient temperature rises, the calorific value Corresponding reduction, thereby saving electricity. PTC has the ability of self-limiting temperature. When the temperature is low, the resistance value is small, so the temperature rises quickly; when the temperature reaches the Curie point, the resistance value rises sharply, so the electric power drops rapidly, so that the appearance of the heating element will remain at a constant temperature Scope.
PTC heater is the first choice for the replacement of other heating elements such as heating wires. It has the advantages of no open flame, constant temperature, automatic power adjustment, high reliability, high heat exchange rate, obvious energy saving effect, safety, and long service life.
