Why do many heaters use PTC heating elements?

PTC heating element, also called PTC heater, consists of PTC ceramic heating element and aluminum tube. This PTC heater has the advantages of low thermal resistance and high heat exchange efficiency, and it is an electric heater with automatic constant temperature and power saving. The outstanding feature is safety performance. Under any application situation, the surface of the electric heating tube heater will not appear "redness", which will cause burns, fires and other safety hazards.

It consists of galvanized external pressure plate, stainless steel corrugated spring leaf, galvanized internal pressure plate, single-layer aluminum radiator, ptc heating plate, double-layer aluminum radiator, nickel-plated copper electrode terminal and pps high-temperature plastic electrode sheath. The product adopts U-shaped corrugated fins, which improves its heat dissipation rate, combines the advantages of adhesion and machinery, and fully considers various thermal and electrical phenomena of ptc heating parts during operation. Strong binding force, excellent heat conduction and heat dissipation performance, high efficiency, safety and reliability. This PTC heater has the advantages of low thermal resistance and high heat exchange efficiency. It is an electric heater with automatic constant temperature and power saving. Its outstanding feature lies in its safety performance, that is, when the fan fails to stop running, the power of PTC heater will automatically drop sharply due to insufficient heat dissipation, and the surface temperature of the heater will be maintained around Curie temperature (generally around 250℃), thus avoiding the phenomenon of "redness" on the surface of electric heating tube heater.

It is characterized by rapid temperature rise, automatic temperature control in case of fan failure, long service life, wide voltage application range, convenient design, free design from low power to high power, non-combustion, safety and reliability. Its advantage is 1. The rapidly heated aluminum plate is denser and has higher thermal efficiency. 2. Health and environmental protection, and no adhesive bonding is healthier. 3. Super long, durable and non-oxidizing, with a service life of 6000 hours.
