Language The power will automatically drop sharply. At this time, the surface temperature of the heater is limited to about the Curie temperature (generally 220 ℃), so as not to produce the "red" phenomenon on the surface of the electric heating tube heater, eliminating the hidden danger of accidents
It works reliably and uses the internal characteristics of PTC heating sheet to control the temperature, which will never exceed the temperature. The operating voltage is very wide: when the operating voltage changes by 2 times, the change of surface temperature is very small. PTC heater adopts element effect and PTCR thermal ceramic element, which is composed of several single pieces combined and bonded with corrugated heat dissipation aluminum strip by high-temperature adhesive. It has the significant advantages of small thermal resistance and high heat exchange efficiency. PTC heater adopts element effect and PTCR thermal ceramic element, which is composed of several single pieces combined and bonded with corrugated heat dissipation aluminum strip by high-temperature glue. It has the remarkable advantages of small thermal resistance and high heat exchange efficiency of electric ball valve.
Its biggest feature lies in its safety, that is, in case of fan failure and locked rotor, the power of PTC heater will automatically drop sharply due to insufficient heat dissipation. At this time, the surface temperature of the heater is limited to about Curie temperature (generally 220 ℃), so as to avoid the "red" phenomenon on the surface of electric heating tube heater and eliminate the hidden danger of accident.
