PTC Electric Heater Working Principle

The PTC electric heater is an electric heater based on semiconductor materials, and its working principle is to use the characteristics of PTC (Positive Temperature Coefficient) materials for heating. PTC material is a special semiconductor material whose resistance increases with temperature, that is, it has a positive temperature coefficient characteristic.

When the PTC high voltage coolant heater is energized, since the resistance of the PTC material increases with temperature, a large amount of heat will be generated when the current passes through the PTC material, which will heat up the PTC material and the surrounding environment. When the temperature rises to a certain level, the resistance value of the PTC material increases sharply, thereby limiting the flow of current, reducing the heating power and reaching a self-stabilizing state.

PTC electric heaters have the advantages of fast response, uniform heating, safety and reliability, etc., and are widely used in household appliances, automobiles, medical treatment, military and other fields. At the same time, because the PTC electric heater has self-stabilizing properties, it also has a good application prospect in temperature control.

It should be noted that the PTC electric heater should avoid overloading and long-term high-temperature operation during use to avoid damage to the PTC material. At the same time, when choosing a PTC electric heater, it needs to be selected and applied according to the actual needs and the use environment.
