An electric heater is an energy converter that converts electrical energy into thermal energy. Maybe many people don't know about PTC electric heaters, but I believe that many people are using products with it, the heaters we use at home, the electric cars we ride, and many electric products. The PTC electric heater is different from ordinary electric heaters in that it heats more uniformly, and has fast heating speed and high heating accuracy. Because of its various advantages, it is widely used in industry.
In addition to being used as a heating element, the PTC thermistor can also function as a switch. It has three functions: a sensitive element, a heater, and a switch. It is called a thermal switch. After the current passes through the element, the temperature rises, that is, the temperature of the heating element rises. When the temperature exceeds the Curie point temperature, the resistance increases, thereby limiting the current increase. Therefore, the decrease in current causes the component temperature to decrease, and the decrease in resistance value causes the circuit current As the temperature increases, the component temperature rises and repeats. Therefore, it has the function of keeping the temperature in a specific range, and it also functions as a switch. Utilizing this temperature resistance characteristic to make a heating source. As heating elements, there are heaters, electric irons, drying cabinets, air conditioners, etc., and they can also protect the electrical appliances from overheating.
