Problems solved by technology

[0002] At present, in life and production, most of the heating materials used are traditional heating wires, silicon carbide and more advanced PTC heating elements. These heating materials generally have a large volume, high hardness, hard and brittle texture, and short service life. The current heating sheet has uneven heating density, and the existing heating structure is difficult to meet the heating of curved surfaces, especially on some parts that require precise control of heating. The existing heating structure has great limitations and cannot meet the energy saving requirements. With the requirement of improving thermal efficiency

Abstract

The invention relates to the technical field of a heating thin film, particularly to a polyester thin film heating sheet. The polyester thin film heating sheet comprises a polyester thin film and a conductive heating layer; the conductive heating layer is electroplated on the polyester thin film; the conductive heating layer is a U-shaped circuit; and a positive electrode connecting point and a negative electrode connecting point are arranged at the two ends of the conductive heating layer respectively. The polyester thin film heating sheet is simple in structure, high in heat efficiency, high in flexibility, and can be applicable to a heating device with any concave and convex surfaces; in addition, the conductive heating layer of the heating sheet can be adjusted according to needs of different heating areas, and 2-13[mu]m far infrared wavelength is generated in operation, so that the heating sheet is beneficial for human health; and in addition, the polyester thin film heating sheet is light in weight, convenient to use and safe.
