PTC heating element products use u-shaped corrugated radiator, which improves its heat dissipation rate, and integrates the advantages of adhesive and mechanical, and fully takes into account various thermal and electrical phenomena of the ptc heating element during operation. It has strong binding force, excellent heat conduction and heat dissipation performance, high efficiency, safety and reliability. This type of PTC heater has the advantages of small thermal resistance and high heat exchange efficiency. It is an automatic constant temperature and electricity saving electric heater. One of its outstanding features is its safety performance, that is, in case of fan failure and shutdown, the PTC heater's power will automatically drop sharply due to insufficient heat dissipation. At this time, the surface temperature of the heater is maintained at about Curie temperature (generally around 250 ℃), so as to avoid the phenomenon of "reddening" on the surface of electric heating pipe heaters
