Abstract
A kind of electric heating membrane structure, including the first polyimide film (1), electric heating function layer (2), the second polyimide film (3) and aluminium sheet (4)；The electric heating function layer (2) is heating resistance wire；The heating resistance wire is fixedly installed on inside the downside of second polyimide film (3)；The lower surface of second polyimide film (3) is snugly fixedly connected with the upper surface of the first polyimide film (1)；The aluminium sheet (4) is snugly fixedly connected with the upper surface of the second polyimide film (3).The structure heating body does not use metal foil, the pollution generated to environment in production process is avoided that, in addition, the influence of plane capacitance is not present using heating resistance wire as heat generating components, the safety coefficient during use will not can be significantly improved the case where surface is charged.
Description
Technical field
The utility model belongs to electroheat technology field, and in particular to a kind of electric heating membrane structure.
Background technology
Traditional Kapton abbreviation PI Electric radiant Heating Films are etched as outer insulator, with metal foil using Kapton
It is afterwards interior conductive heating unit, is formed through high temperature and pressure heat seal.This kind of heating film produces due to the use of etch process, has to environment
A degree of pollution, production process is not environmentally.In addition, powerful Electric radiant Heating Film must use metal material that could reach well
To Homogeneouslly-radiating heating effect, due to being influenced by plane capacitance, metal material mostly charges, and has some potential safety problems,
Being easy, which makes user in use, the danger of electric shock.
Invention content
In view of the above-mentioned problems of the prior art, the utility model provides a kind of electric heating membrane structure, the structure heating body
Metal foil is not used, is avoided that the pollution generated to environment in production process, in addition, using heating resistance wire as heating part
The influence of plane capacitance is not present in part, will not have the case where electrification on surface, can significantly improve the peace during use
Overall coefficient.
To achieve the goals above, the utility model provides a kind of electric heating membrane structure, including the first polyimide film, electric heating
Functional layer, the second polyimide film and aluminium sheet；
The electric heating function layer is heating resistance wire；The heating resistance wire is fixedly installed on second polyimide film
Downside inside；
The lower surface of second polyimide film is snugly fixedly connected with the upper surface of the first polyimide film；
The aluminium sheet is snugly fixedly connected with the upper surface of the second polyimide film.
In the technical scheme, by making electric heating function layer can be effective without using metal foil using heating resistance wire
Avoid metal foil in etching process to the environment produced pollution.Using heating resistance wire as heat generating components, due to same
The practical laying area of resistance wire is much smaller than the area that metal foil is laid under constant power, so as to avoid the feelings of surface electrification
Condition occurs, and improves the security performance during use.
Further, in order to radiate uniformly, the shape and size phase of first polyimide film and the second polyimide film
Together, and each edge flush be arranged；The size of the aluminium sheet is identical with the size of the first polyimide film.
Further, in order to make Electric radiant Heating Film that there is good heat conductivility, between first polyimide film and aluminium sheet, aluminium
Using a kind of bonding in heat-conducting silicone grease, heat-conducting glue or heat conduction bonding cream between plate and the second polyimide film.
The utility model is simple in structure, simple production process, manufacturing cost are low, is easy to industrialized production.

The practical laying area of resistance wire is much smaller than the area that metal foil is laid under constant power, so as to avoid the feelings of surface electrification
Condition occurs, and improves the security performance during use.
In order to radiate uniformly, first polyimide film 1 is identical with the shape and size of the second polyimide film 3, and
Each edge flush it is arranged；The size of the aluminium sheet 4 is identical with the size of the first polyimide film 1.
Further, in order to make Electric radiant Heating Film that there is good heat conductivility, between first polyimide film 1 and aluminium sheet 4,
Using a kind of bonding in heat-conducting silicone grease, heat-conducting glue or heat conduction bonding cream between aluminium sheet 4 and the second polyimide film 3.
The utility model is simple in structure, simple production process, manufacturing cost are low, is easy to industrialized production.
Although the embodiments of the present invention have been shown and described above, it is to be understood that above-described embodiment is
Illustratively, it should not be understood as limiting the present invention, those skilled in the art are in the scope of the utility model
Inside it can make changes, modifications, alterations, and variations to the above described embodiments.
