Abstract
The utility model provides am electric heating film, belonging to the electric heating field; the electric heating film consisting of an electric heating film and an insulation basal body, wherein the insulation basal body is covered by the electric heating film which is concave-convex shaped, both ends of the electric heating film are externally connected with lead wires; due to the concave-convex shape, parts of the electric heating film are different in thickness, the concave parts are thick and the convex parts are thin; also due to the concave-convex shape, layers of the electric heating film are different in resistance, which effectively avoids the reduction of the service life of the utility model caused by the unfocused heating of the electric heating film or the burnout of electrodes due to the partial overheat. The electric heating film of the utility model is stepladder shaped from inside to outside, and the thickness of both ends of the electric heating film is larger than that of the middle parts, taking a shape of a stepladder with concave middle parts and convex end parts. The utility model has the advantages of reasonable design, high thermal efficiency, energy conservation, safety, low cost and long service life.
Description
Technical field
A kind of Electric radiant Heating Film of the utility model belongs to field of electric heating, particularly relates to a kind of Electric radiant Heating Film.
Background technology
Dull and stereotyped Electric radiant Heating Film is that Electric radiant Heating Film is being covered uniformly on the insulating body material, on surfaces such as pottery, quartz glass, adopt high temperature sintering or other method, Electric radiant Heating Film is firmly being covered on the insulating body material surface, Electric radiant Heating Film is same integral planar shape, and the thickness of Electric radiant Heating Film has certain influence to resistance.When heating power, whole planar Electric radiant Heating Film is easy to the power electrode contact position and produces big overcurrent and cause that heating is too high burns electrode and reduce useful life.
Summary of the invention
The purpose of this utility model is to avoid weak point of the prior art and a kind of heat efficiency height is provided, and is energy-conservation, safety, long service life, the uniform Electric radiant Heating Film of generating heat.
The purpose of this utility model reaches by following measure, the heating of Electric radiant Heating Film is that electric current is flowed through resistance and produced heat and loose outward, the size of caloric value depends on resistance, Electric radiant Heating Film of the present utility model makes on the Electric radiant Heating Film resistance value because of certain difference, and cause the difference of electric heating amount, Electric radiant Heating Film is made up of Electric radiant Heating Film and insulating body, on insulating body, covering Electric radiant Heating Film, Electric radiant Heating Film is lenticular, at the two ends of Electric radiant Heating Film external lead wire, the lenticular formation thickness of Electric radiant Heating Film difference, little at recessed segment thickness, big at the segment thickness of projection, Electric radiant Heating Film is because concavo-convex each layer resistance value difference, can effectively avoid Electric radiant Heating Film heating not concentrate, or part is overheated burn electrode and reduces useful life and fall.
Electric radiant Heating Film of the present utility model is stepped from inside to outside, and the two-end thickness of Electric radiant Heating Film is greater than the thickness of centre, and is stepped, and mid portion is recessed, the two end portions projection.
Electric radiant Heating Film of the present utility model is that the two-end thickness of Electric radiant Heating Film is less than the thickness of centre, and is stepped by outer interior to interior stepped.The mid portion projection, two end portions is recessed.Stepped.
Electric radiant Heating Film of the present utility model is lenticular, and the two-end thickness of Electric radiant Heating Film is less than the thickness of centre, the mid portion projection, and two end portions is recessed.
Electric radiant Heating Film of the present utility model is lenticular, and the two-end thickness of Electric radiant Heating Film is greater than the thickness of centre, and mid portion is recessed, the two end portions projection.
The bossing of Electric radiant Heating Film of the present utility model can be overlapped by a plurality of electric membranous layers and form.
Electric radiant Heating Film of the present utility model can be a rectangle, also can be semicircle, also can be polygon, or oval, and each rank width of Electric radiant Heating Film can equate, also can be unequal, decides according to the needs of electric heating amount.The utility model is reasonable in design, and heat efficiency height is energy-conservation, safety, and cost is low, long service life.
