Description
Technical field
This utility model belongs to metal processing sectors, in particular it relates to a kind of metal flexible heating film.
Background technology
Metal flexible Electric radiant Heating Film is the thin film heater of the translucent of a kind of sandwich structure or all-transparent, and upper and lower surface is the insulation film of temperature tolerance, excellent insulating property, the middle resistance circuit made for specific alloy paper tinsel.
Metal flexible Electric radiant Heating Film generally has two classes: the PET metal electric heating membrane of megathermal polyimide metal Electric radiant Heating Film and low form.There is the dielectric strength of excellence；Excellent dielectric strength；Excellent heat conduction efficiency；Heater adopts special Alloy Foil to make, and has the resistance stability of excellence.This allows it to be widely applicable for heating art and be obtained in that at a relatively high temperature control precision.
At present, China is primarily present following patent:
Patent publication No.: CN101765252A, discloses a kind of electrothermal film heater based on metal base, including: in order to conduct the metal base of heat energy, being located at the insulating barrier between Electric radiant Heating Film and metal base, Electric radiant Heating Film is metal oxide conducting film；Electric radiant Heating Film is connected to metal electrode, and metal electrode connects with power supply.Metal base adopts light metal and alloy thereof as base material；Described insulating barrier is by micro-plasma ceramic technique or oxidation technology, at the generated in-situ micro-plasma ceramic layer of metallic substrate surface；Electric radiant Heating Film is coated with or is sintered in micro-plasma ceramic layer surface.Owing to insulating barrier is by micro-plasma ceramic technique or oxidation technology, at the generated in-situ micro-plasma ceramic layer of metallic substrate surface；Ensureing that between micro-plasma ceramic layer and metal base, adhesion is strong, after heating, micro-plasma ceramic layer peels off without from metal base repeatedly.But, it is not good that this electrothermal film heater can not solve insulating barrier heat conductivility, have that unit cross-sectional area power density is big, surface temperature is high, differential expansion coefficient is big, yielding, work time have sound, have the place of line with heating function to cause the problems such as excessive the brought heating wire short circuit of differential expansion coefficient, sparking, too fast oxidation because temperature is significantly high in preparation.
Utility model content
For solving above-mentioned Problems existing, the purpose of this utility model is in that to provide a kind of metal flexible heating film.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of metal flexible heating film, it is characterized in that, including: metal electrode and the first insulating thin layer stacked gradually from bottom to top, metal heating layer, the second insulating thin layer, insulation heat-conducting layer；Described metal heating layer is evenly distributed with some electrical conductivity alloy bars；Described metal electrode electrically connects with metal heating layer；Described first insulating thin layer is evenly applied to described metal heating layer lower surface；Described second insulating thin layer is evenly applied to described metal heating layer upper surface；Described insulation heat-conducting layer is graphite linings, is laid in described second insulating thin layer upper surface, its content of graphite >=99%.
Further, described electrical conductivity alloy bar is rustless steel, aluminum, pyrite, corronil, copper or other electric resistance alloys.
Separately, described first insulating barrier and the second thickness of insulating layer are 0.08 ~ 0.2mm.
Separately having, described first insulating thin layer and the second insulating thin layer are PET or polyimide layer.
Again, described metal heating layer thickness is 0.02 ~ 0.03mm.
Further, described metal heating layer both sides are equipped with metal current-carrying bar, described electrical conductivity alloy bar connects in addition in parallel by metal current-carrying bar.
The beneficial effects of the utility model are in that: taken up space minimum；Weight is extremely light；Very thin thickness.Form and dimension is extremely flexible, is particularly suitable for making the flexible electric heating membrane component that area is little；Adopt planar heating mode, allow that surface power density is big.It is better that these series of products have homogeneous heating performance, and the rate of heat addition is feature faster；Different heating powers can be met require and heating-up temperature requirement at different area position；Thermal inertia is little, and temperature control precision is high.Insulation film as protective layer has extremely low saturated vapor pressure, and gas release performance is extremely low, has the resist chemical performance of excellence, anti-microbial property and radiation resistance simultaneously.Therefore, the Electric radiant Heating Film that this utility model produces be applicable to vacuum environment and oily and most of chemicals (as acidity, chemical solvent, alkali liquor) environment that contacts.Can become one with slim heat-barrier material easily, it is provided that with the lightweight heating of thermal insulation layer.The heating film that this utility model produces is safe and reliable, long service life；Utilize the anisotropic heat conductivity of graphite film, the horizontal heat conductivity of graphite film is very big on the one hand, rapidly the amount of localized heat that electrical conductivity alloy bar produces being diffused into entirety, graphite film vertical direction heat conductivity is relatively low on the other hand, can function well as the effect preventing heat loss；Thus solving that heating film unit cross-sectional area power density is big, surface temperature is high, differential expansion coefficient is big, yielding, work time have sound, have the place of line with heating function to cause the problems such as excessive the brought heating wire short circuit of differential expansion coefficient, sparking, too fast oxidation because temperature is significantly high in preparation.
