Energy-saving PTC electrothermal film

Abstract

The invention discloses an energy-saving type PTC electrothermal film, which comprises a covering film and a bottom film. According to the invention, an outer layer film is subjected to strength supplementing through the components of the outer layer film to achieve the protection of the outer layer film on a middle interlayer; graphene is used as a main material in the middle interlayer, the material is slim, electric conductivity and thermal conductivity are high, the graphene can emit far infrared rays with specific wavelength, water and protein molecules forming cells in a human body are acted, and heat energy generated in the process of generating neat and neat promoting cell activity enables the body temperature to rise, so that capillaries are expanded, blood circulation is smooth,metabolism is enhanced, discharge of various waste and toxic substances in the body is promoted, and far infrared rays can enable air to become warm by emitting radiant heat; and the structure can enable the electrothermal film to show the remarkable power reduction rate along with temperature changes, so that the energy-saving effect is achieved, local overheating can be avoided, and the far infrared electrothermal film is safer.

Description

technical field [0001] The invention relates to the technical field of electrothermal film, in particular to an energy-saving PTC electrothermal film. Background technique [0002] Electric heating film is divided into high temperature and low temperature electric heating film. High-temperature electric heating film is generally used in electronic appliances, military, etc., and now the electric heating film produced by science and technology. The electrothermal film heating system is different from the point heating system represented by radiators, air conditioners, and radiators, and the line heating system represented by heating cables. It is a low-carbon heating technology developed by modern aerospace technology in the field of surface heating. product. [0003] Low-temperature electric heating film is a translucent polyester film that can generate heat after being energized. It is made of conductive special ink and metal current-carrying strips, which are processed a...

AI Technical Summary

Problems solved by technology

The electric heating film heating method does not consume water, does not occupy land, has independent switch, saves energy and materials, meets the policy orientation of emission reduction and low carbon, and has broad development prospects. The existing electric heating film cannot change the power with temperature changes, and cannot achieve energy saving. effect, and will lead to local overheating of the electric heating film, and the existing electric heating film due to the lack of external protection seriously reduces its service life and is not safe to use
