Electrothermal film has high thermal efficiency and radiation heat. PTC circulates air by the fan, which is similar to air conditioner.
PTC is positive temprature coefficient which means when the temperature of the heating element rise, its resistance will rise (ordinary metal material has the characteristic, but the resistance of the material increases rapidly with the rise of temperature ), and the heating power decrease, and it will not reach the ignition point because of local covering lead to sharp rise in temperature. It is also known as self-regulating heating element, that is, the material itself has the function of limiting the rise of temperature , rather than limiting the temperature through the laid temperature sensor on the ground. Due to the characteristics of PTC, it is considered as a safe electric heating in the market, so many do not have the characteristics of the PTC material, also boast they are. This should be paid attention to.
Electrothermal film heating system is different from dot mode heating system such as the radiator, air conditioner, heating radiator and streamlined heating system such as the heating cable, and low carbon supply heating high-tech products which adopts modern aerospace technology in face heating field. The electrothermal?film is a semitransparent polyester film which will heat once charged with electricity, and it is made of a conductive special ink and processing and hot-pressing of a metal carrier flow strip in the insulating polyester film. When working, it takes the electrothermal?film as the heating element, and the heat is sent into space in the form of radiation, so that the human body and the object are warm at first. Tthe integrated effect is better than the traditional convection heating mode. The low-temperature radiant electric heating film system is composed of a power supply, a temperature controller, a connecting piece, an insulating layer, an electrothermal?film and a finish coat. The power supply is connected with an electrothermal film through a conducting wire, and the electric energy is transformed into heat energy. Because the electric heating film is a pure resistance circuit, the conversion efficiency is high, and the majority (98%) is converted into heat energyin except a small partial loss (2%).
