Problems solved by technology

In addition, the heating wire is not insulated. If it is placed in multiple turns or in multiple layers, a certain space must be left or separated by a filling material such as asbestos, or made into a spring type. Therefore, the manufacture of the heating wire type heating device is relatively complicated, and the filling material Substances harmful to human health may be decomposed after being heated
More importantly: the thermal efficiency of the heating wire type heating device is low

Abstract

A multifunctional built-in electric heating thin-film type heating structure comprises an electric heating thin-film, and is characterized in that an upper insulating layer is arranged on an upper surface of the electric heating thin-film, and a lower insulating layer is arranged on a lower surface, and the upper and lower insulating layers are clamped inside a heated body. The multifunctional built-in electric heating thin-film type heating structure is of a built-in structure. The electric heating thin-film, the insulating layers and a thermal-protective layer are clamped inside the heated body, so that the electric heating thin-film and the heated body are dissolved integrally, therefore effectively improving the heat efficiency and shortening the heating time. In addition, the thermal-protective coating layer can be coated on one of the two faces of the electric heating thin-film as demanded to form an unidirectional heat conducting function, so that the heat efficiency can be further improved. The multifunctional built-in electric heating thin-film type heating structure provided by the invention is safe and reliable, accurate in temperature detection and convenient for controlling power.

Description

technical field [0001] The invention relates to a heating structure, in particular to a multifunctional built-in electrothermal film type heating structure. Background technique [0002] At present, almost all electrothermal conversion uses electric heating wire, which is installed in the heating device as a kind of electric heating body. Heating wire is the concept of "wire". Considering the manufacturing technology and production cost, the wire diameter of the heating wire can only be divided into several specifications, and its cross-sectional area cannot be changed arbitrarily, that is to say, the power of the heating wire basically depends on the length. In addition, the heating wire is not insulated. If it is placed in multiple turns or in multiple layers, a certain space must be left or separated by a filling material such as asbestos, or made into a spring type. Therefore, the manufacture of the heating wire type heating device is relatively complicated, and the fill...
