At present, Electric radiant Heating Film product both domestic and external mainly is the low-temp radiating electrothermal membrane that adopts polyethylene film or polyester film to make as substrate, poly fusing point is about 110 ℃, the fusing point of polyester film is about 256 ℃, for the Electric radiant Heating Film product of heating temp scope at 20 ℃-800 ℃, these two kinds of materials can not satisfy the needs of middle temperature, high-temperature electric heating membrane product; In addition since existing Electric radiant Heating Film product adopt two be parallel to each other be arranged at conducting metal current-carrying bar between the substrate, when situation to the destruction of current-carrying bar appears in Electric radiant Heating Film when installing or use, Electric radiant Heating Film will be interrupted heating.
The purpose of this utility model is: a kind of infrared radiated electric film is provided, and the temperature range of adaptation is wide, and the destruction to metal current-carrying bar of causing for mechanical wounding has protection effect, does not influence the operate as normal of whole Electric radiant Heating Film system.
The utility model is achieved in that a kind of infrared radiated electric film, comprises double-deck substrate, is sealed in the conductive electrode parallel to each other in the substrate, the heater of laying between the conductive electrode; Described conductive electrode is made up of basic electrode and combination electrode, and basic electrode and combination electrode be parallel to each other to overlap setting.
Described substrate is an inorganic silicate, and thickness is between the 0.5mm-4mm.
Described substrate is an organic sheet, and thickness is between the 0.5mm-4mm.
Basic electrode in the described conductive electrode directly is connected with heater, and combination electrode is arranged at a side on basic electrode and plane, heater place.
Described basic electrode is an ag paste electrode, and combination electrode is an alloy electrode.
Described alloy electrode is titanium, nickel, copper, aluminum alloy anode.
The utility model is owing to the substrate that adopts inorganic silicate or organic sheet to make, and heatproof and ageing-resistant performance are good, can adapt to all temps scope; Overlap the conductive electrode of forming by basic electrode and combination electrode that is provided with each other owing to adopt, when making Electric radiant Heating Film be subjected to mechanical damage, can not influence heater work owing to the fracture of a conductive electrode.
Below in conjunction with accompanying drawing the utility model is described further.
