H1Y PTC air Heater is a patented product developed by our company, which is composed of PTC chip, aluminum plate (copper plate) heat sink and lead wire. This product makes full use of a heating device designed with PTC thermistor's constant temperature heating characteristics. The principle is that after the PTC thermistor is powered on, it self-heats to increase the resistance value to enter the jump zone, and the heat is dissipated through the aluminum plate (copper plate), so that the heated object continuously obtains sufficient heat to meet the product requirements. After the PTC is heated at a constant temperature, its surface temperature also maintains a constant value. This temperature value is related to the Curie temperature of the PTC thermistor, external voltage, ambient temperature, product structure, etc. Our company can design different shapes according to various product requirements A heater with high power, high power and slow heating speed, the heater has the advantages of no open flame, constant temperature heating, long life, safety, environmental protection and energy saving.
