Abstract
The present utility model discloses an electrothermal film. The film comprises a heating layer, a cable conductor, an inner protection layer and an outer protection layer, the cable conductor comprises a backflow conducting wire and a power supply conducting wire, two copper electrodes, which are plated on two ends of the electrothermal film, are respectively connected with the backflow conducting wire and the power supply conducting wire, the inner protection layer is laid above the heating layer, the outer protection layer is wrapped outside the inner protection layer, the heating layer is a sheet-shaped structure, and a conductive printing ink made of carbon crystalline materials is printed on the heating layer. Through adopting the film, current leakage and slow heat-transfer speed of the electrothermal film caused by distribution capacitance can be effectively solved.
Description
Technical field
The utility model relates to a kind of Electric radiant Heating Film, is specifically related to the Electric radiant Heating Film that a kind of zone of heating is a laminated structure.
Background technology
Electrothermal film technology development at present rapidly; Particularly building aspect consumption is big, be widely used, and along with expanding economy; People are increasingly high for the demand of the equipment of heating; What the zone of heating of Electric radiant Heating Film adopted in the past is the corrugated strip heating wire that walks abreast, and heat-transfer rate is slower, and occurs easily because capacitance profile causes the problem of leakage current.
The utility model content
Be to solve the deficiency of prior art, the purpose of the utility model be to provide a kind of can Electric radiant Heating Film, effectively solve the slow problem with the electric current leakage of Electric radiant Heating Film heat-transfer rate.
To achieve these goals; The utility model adopts following technical scheme: a kind of Electric radiant Heating Film is provided, comprises: zone of heating, cable, inner protective layer and external protection, and said cable comprises: backflow lead, current supply line; Two copper electrodes of two ends plating of said Electric radiant Heating Film; Connect said backflow lead and current supply line respectively, said inner protective layer is layered on above the zone of heating, and said external protection is wrapped in the inner protective layer below; Said zone of heating is a laminated structure, has printed the electrically conductive ink that one deck is processed with carbon crystal material above.
In preferred embodiment of the utility model, said inner protective layer is a polyester film.
In preferred embodiment of the utility model, said external protection is the static electro-magnetic screen layer.
The beneficial effect of the utility model is:
Can solve Electric radiant Heating Film effectively because of having the problem and the slower problem of Electric radiant Heating Film heat-transfer rate of the electric current leakage that causes owing to distributed capacitance.
Description of drawings
Fig. 1 is the structural representation of the Electric radiant Heating Film of the utility model.
The implication of Reference numeral among the figure:
1, zone of heating, 2, inner protective layer, 3, external protection, 41, the backflow lead, 42, current supply line.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection range of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
Fig. 1 is the structural representation of the utility model Electric radiant Heating Film.
With reference to shown in Figure 1, the utility model Electric radiant Heating Film comprises zone of heating 1, inner protective layer 2 and external protection 3, cable, and cable comprises: backflow lead 41, current supply line 42; Two copper electrodes of two ends plating of Electric radiant Heating Film; Connect backflow lead 41 and current supply line 42 respectively, inner protective layer 2 is layered on above the zone of heating 1, and external protection 3 is wrapped in inner protective layer 2 belows; Zone of heating is a sheet, has improved heat-transfer rate.
As a kind of preferred version, inner protective layer 2 is a polyester film.
As a kind of preferred version, external protection 3 is the static electro-magnetic screen layer.
Be different from prior art, the zone of heating of Electric radiant Heating Film 1 adopts is the electrothermal layer of the laminated structure that walks abreast, can solve effectively Electric radiant Heating Film because of existing because problem and the slower problem of Electric radiant Heating Film heat-transfer rate that the electric current that distributed capacitance causes leaks.
The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
