The heating principle of the electrothermal?film The so-called?film heating material is a layer of conductive film formed on the surface of insulation material after being processed on the surface of the insulation material. The conductive particles form mesh-shaped lattice structure on the surface of the insulating layer, and the various additives added in the film can adjust the power of the electrothermal?film. After being electrified, this layer of film can achieve conversion, so people also call it electrothermal?film.
The electrothermal?film is a kind of exothermic material made of special conductive macromolecule material matched with metal current-carrying strip, hot melted between the insulating film bodies, which will produce heat after being electrified mainly used for heating element. The electrothermal?film is divided into high temperature electrothermal?film and low temperature electrothermal?film. High temperature electrothermal?film is generally used in electric products, military and so on, the electrothermal?film produced by present science and technology. The low temperature electrothermal?film is a kind of semitransparent polyester film which can produce heat after being electrified, which is made by processing and hot-pressing the conductive special ink and metal current-carrying strip between the insulating polyester films. Electrothermal?film acts as heating element during work, sending heat into space in the form of radiation, warming the human body and the object first, whose integrated effect is better than the traditional convection heating mode. The low temperature radiation electrothermal film system is composed of power supply, temperature controller, adapting piece, insulating layer, electrothermal?film and finish?coat. The power supply is connected with electrothermal film through wire, converting the electric energy into heat energy. Because the electrothermal?film is pure resistance circuit, the conversion efficiency is high. In addition to a small part of loss (2%), the vast majority (98%) is converted into heat energy.
The electrothermal?film is the electrical heating element which directly converts electric energy into heat energy, belonging to the huge family of electric heating products just like electric heated tube, electrical bar, electric hot plate, electric heater, electric cooker and induction cooker. But what different is that electrothermal?film is still a relatively new product category in domestic with a application history of only a short period of ten years or so, whose application field is far not as broad as other electrothermal products, so people's cognition and comprehension on the electrothermal film have not reach all-pervading degree.
To achieve your desired results, there are too many affected factors, such as the thermal insulation condition, clear space condition and article stacking condition and so on in your room, all of which can directly affect the efficiency of the electrothermal film electric radiator. You can create a small space and heated intensively to achieve better cold-proof effect, such as using screen, retaining heat in a small space to achieve the effect of heating and cold prevention effect. Thus saving electric charge as well.
Electrothermal film heating system is low-carbon heating supply high-tech products which is different from the dot mode heating system represented by radiator, air-condition and heating radiator; and the streamlined heating system represented by heating cable, researched and developed by using aerospace flight technology in the surface heating field. The electrothermal?film is divided into high temperature electrothermal?film and low temperature electrothermal?film. High temperature electrothermal?film is generally used in electric products, military and so on, the electrothermal?film produced by present science and technology. The low temperature electrothermal?film is a kind of semitransparent polyester film which can produce heat after being electrified, which is made by processing and hot-pressing the conductive special ink and metal current-carrying strip between the insulating polyester films.
