The heating medium used in the heating sheet is relatively large, and the electric heating film is divided into high-temperature and low-temperature electric heating films. High-temperature electrothermal film is generally used in electronic appliances, military and so on. Now it is produced by science and technology. Low-temperature electrothermal film is a kind of translucent polyester film, which will heat up after being electrified. It is made of conductive special ink and metal current-carrying strip through processing and hot pressing between insulating polyester films. When working, the electrothermal film is used as the heating element, which sends heat into the space in the form of radiation, so that the human body and objects can be warmed first, and its comprehensive effect is better than the traditional convection heating method. The low-temperature radiation electrothermal film system consists of power supply, temperature controller, connector, insulation layer, electrothermal film and decorative layer. The power supply is connected with the electrothermal film through wires to convert electric energy into heat energy. Because the electrothermal film is a pure resistance circuit, its conversion efficiency is high, except for a small part of the loss (2%), most (98%) is converted into heat energy.
