1, the rapidly heated aluminum sheet is denser and has higher thermal efficiency.
2, health and environmental protection, non-adhesive bonding is healthier.
3, durable and non-oxidizing, with a service life of 6000 hours.
4. The thermal efficiency of 4.PTC heater is up to 99%.
Second, the shortcomings:
1, no energy saving.
2. Metal electrothermal materials are easy to oxidize at high temperature, with power attenuation and short service life. Because its metal is flat, its contact area with air is large and its life is shorter than that of metal wire.
Extended data
Ptc heating element products use U-shaped corrugated fins to improve its heat dissipation rate, and combine the advantages of adhesion and machinery, fully consider various thermal and electrical phenomena when PTC heating element works, and have strong adhesion, 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.
