Abstract
The present utility model discloses an electrothermal film for reducing electromagnetic radiation. The film comprises two layers of carbon heating strips which are insulated and parallel, metal bus bars for respectively pressing on the end part of each layer of carbon heating strips to electrically connect with the carbon heating strips, and polyester films for pressing and sealing the carbon heating strips and the metal bus bars, and the lower layer of metal bus bars are opposite to the lower layer of metal bus bars. The electrothermal film is provided with double layers of carbon heating strips and metal bus bars, and the lower layer of metal bus bars are opposite to the lower layer of metal bus bars. The opposite metal bus bars of the upper and lower layers are respectively connected with a live wire and a zero line, thus generated magnetic fields of the upper and lower layers are same in magnitude and opposite in direction, mutual offset can be realized, good demagnetization effects can be realized, and electromagnetic radiation of the electrothermal film can be effectively reduced.
Description
Technical field
The utility model relates to the electrothermal film technology field in order to heating.
Background technology
Electric radiant Heating Film is a kind of electric pyrogenicity film, belongs to the plane heating, is widely used in heating system.Electric radiant Heating Film normally at the carbon heating bar of polyester film printing parallel arrangement, is then suppressed two strip metal busbars at the two ends of these carbon heating bars, compound one deck polyester film again gets up carbon heating bar and metal busbar press seal at last.Two strip metal busbars are used for respectively connecting live wire and the zero line of civil power.This Electric radiant Heating Film can produce electromagnetic radiation when work, long-term use can jeopardize health.Therefore, be necessary to research and develop a kind of Electric radiant Heating Film that reduces electromagnetic radiation.
The utility model content
The technical problems to be solved in the utility model provides a kind of Electric radiant Heating Film that reduces electromagnetic radiation.
For solving the problems of the technologies described above the technical scheme that adopts: a kind of Electric radiant Heating Film that reduces electromagnetic radiation, it is characterized in that: the end that include the carbon heating bar of the parallel arrangement of two-layer insulation isolation, is compressed on every one deck carbon heating bar respectively is with the metal busbar that is electrically connected the carbon heating bar and polyester film that carbon heating bar and metal busbar press seal are got up, wherein bilevel metal busbar be set as mutually over against.
Concrete, described carbon heating bar and metal busbar press seal are between the interlayer that three strata ester films form, and the two ends of every one deck carbon heating bar all are suppressed with the metal busbar.In fact, described Electric radiant Heating Film with double-deck carbon heating bar and metal busbar also can be formed with the center line docking perpendicular to the carbon heating bar by the carbon heating bar of individual layer and the Electric radiant Heating Film of metal busbar.
The beneficial effect that adopts the utility model to bring: the utility model is set as Electric radiant Heating Film the Electric radiant Heating Film with double-deck carbon heating bar and metal busbar, and bilevel metal busbar mutually over against.By will be up and down two-layer over against the metal busbar connect respectively live wire and zero line, up and down two-layer magnetic field equal and opposite in direction, the opposite direction that produce are therefrom cancelled out each other between the two, have better erasure effect, can effectively reduce the electromagnetic radiation of Electric radiant Heating Film.
Description of drawings
Fig. 1 is the front view of embodiment one;
Fig. 2 is embodiment one sectional view;
Fig. 3 is the structural representation of embodiment two.
Embodiment
Embodiment one: shown in Fig. 1-2, a kind of Electric radiant Heating Film that reduces electromagnetic radiation, include the carbon heating bar 1 of the parallel arrangement of two-layer insulation isolation, the two ends of every one deck carbon heating bar 1 all are suppressed with metal busbar 2, this two-layer carbon heating bar 1 and metal busbar 2 press seals are between the interlayer that three strata ester films 3 form, by polyester film 3 carbon heating bar 1 and metal busbar 2 press seals are got up, wherein bilevel metal busbar 2 be set as mutually over against.The metal busbar 2 at every one deck two ends connects respectively one group live wire and zero line, being electrically connected the carbon heating bar 1 of this layer, and levels over against the polarity of two strip metal busbars 2 to stagger, be connected with zero line with live wire respectively.Like this, this Electric radiant Heating Film after energising, up and down two-layer be parallel to each other over against metal busbar 2 and carbon heating bar 1 magnetic field that can produce equal and opposite in direction, opposite direction, cancel out each other between the two, reach erasure effect, effectively reduce the electromagnetic radiation of Electric radiant Heating Film.
Embodiment two: as shown in Figure 3, utilization is become the carbon heating bar 1 of individual layer by two layers polyester film 3 with metal busbar 2 press seals Electric radiant Heating Film, with the center line perpendicular to carbon heating bar 1 the Electric radiant Heating Film docking is formed, with the two strip metal busbars 2 that are compressed on respectively the two ends of carbon heating bar 1 be up and down two-layer mutually over against, like this, this Electric radiant Heating Film is after energising, up and down two-layer be parallel to each other over against metal busbar 2 and carbon heating bar 1 also can produce equal and opposite in direction, the magnetic field of opposite direction, cancel out each other between the two, reach erasure effect, effectively reduce the electromagnetic radiation of Electric radiant Heating Film.
Claims (3)
1. Electric radiant Heating Film that reduces electromagnetic radiation, it is characterized in that: the end that include the carbon heating bar of the parallel arrangement of two-layer insulation isolation, is compressed on every one deck carbon heating bar respectively is with the metal busbar that is electrically connected the carbon heating bar and polyester film that carbon heating bar and metal busbar press seal are got up, wherein bilevel metal busbar be set as mutually over against.
2. the Electric radiant Heating Film of minimizing electromagnetic radiation according to claim 1 is characterized in that: described carbon heating bar and metal busbar press seal are between the interlayer that three strata ester films form, and the two ends of every one deck carbon heating bar all are suppressed with the metal busbar.
