With simple structure and convenient process, the low temperature radiation electric heating film has higher ability of anti-bending and anti-stretching deformation, and guarantees the long-term stable work of the heating units connected in parallel, as well as extends the application scope of the low temperature radiation electric heating film in various environments with acute deformation.
Description
Technical field
The utility model belongs to infrared low-temp radiating electric heater unit, relates in particular to that a kind of ability of anti-deformation is strong, the low-temp radiating electrothermal membrane of applied range.
Background technology
Low-temp radiating electrothermal membrane is the low-temperature heating device that can generate heat after a kind of energising, and existing low-temp radiating electrothermal membrane generally adopts the translucent polyester film, and by conductive special printing ink, metal current-carrying bar is made between insulation polyester film through processing, heating.Operation principle is to be heater with the Electric radiant Heating Film, and heat is sent into the room with the form of radiation, and it is warm that human body and object are at first obtained, and its resultant effect is better than traditional convection current heating system.Power supply is communicated with Electric radiant Heating Film through lead, and electric energy is converted into heat energy.Because Electric radiant Heating Film is the pure resistance element, so its conversion efficiency height, except that the sub-fraction loss, the overwhelming majority is converted into heat energy.The working temperature of low-temp radiating electrothermal membrane is below 50 ℃, with the form of infrared radiation to indoor heating.9.5 microns the infrared radiation heat that Electric radiant Heating Film produces, because even when indoor temperature distribution is than the tradition heating during radiant heating, room wall surface temperature improves, and has reduced the cold emission of wall to human body, make human body have best comfort, be mainly used in the heating of residential quarters building.
In use there are the following problems for existing low-temp radiating electrothermal membrane.At first; though use because the low-temp radiating electric heating film is mainly fixed form; can not be subjected to quick deformation and stress influence; but because the problem of installing; usually can be subjected to because of placing or the deformation of fixture and collapse that the long-term deformation and the stress that produce stretch, the influence of extruding, under long-term effect, heater is because electrically conductive inks or the strip metal sheet of adopting stressed less with deformation more; the phenomenon of heater outage takes place easily, influences the operation of Electric radiant Heating Film.And occasion big in a lot of deformation or that stress is concentrated then can not adopt the low-temp radiating electrothermal membrane of this structure to add hot work.
The utility model content
The purpose of this utility model provides the low-temp radiating electrothermal membrane of deformation such as a kind of simple in structure, bend resistance and stretching, has solved that the heater that existing low-temp radiating electrothermal membrane exists opens circuit easily, the defective of anti-deformation weak effect.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of low-temp radiating electrothermal membrane comprises fexible film and middle electric heating layer thereof, it is characterized in that described electric heating layer is made up of heater in parallel between two conductive strips that be arranged in parallel and conductive strips, and heater is the resistor disc of continuous square-wave form.
Specifically, the described conductive strips of this low-temp radiating electrothermal membrane are copper sheet, and conductive strips and heater are an overall structure.
Described heater is for being the resistor disc of continuous square-wave form on the electric heating layer plane.
Described fexible film is the translucent thin film sheet of fire-retardant class polystyrene, polyester or polytetrafluoroethylmaterial material, and fexible film also is pasted with the high-strength thin-film protective layer outward.
Also be provided with infrared-reflecting layers between the fexible film of described low-temp radiating electrothermal membrane one side and the electrothermal layer.
The heater of this low-temp radiating electrothermal membrane is the resistor disc in the continuous square-wave form on electric heating layer plane, can withstand the bigger stretching and the deformation of length direction, the stressed of Width also can multi-directionly disperse simultaneously, bent angle increases, this not only can effectively be avoided in the use Electric radiant Heating Film because of unexpected or long-term deformation or stretching and impaired, also enlarged simultaneously the range of application of low-temp radiating electrothermal membrane, as the vehicle backing rear-view mirror under the long-term vibrational state, the chemical pipeline that telescopic variation is bigger and heat clean decontamination occasion etc.
This heater and conductive strips are overall structure, strengthen its bend resistance ability.After between the fexible film of low-temp radiating electrothermal membrane one side and the electrothermal layer infrared-reflecting layers being set, can realize the single face heating effect.
The beneficial effects of the utility model are, this low-temp radiating electrothermal membrane is simple in structure, and is easy to process, has higher bend resistance and tensile deformation ability, can guarantee the long-term normal steady operation of heater in parallel, expand the range of application of low-temp radiating electrothermal membrane in numerous deformation intense environment.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
Fig. 1 is the overall structure schematic diagram of the concrete real-time mode of the utility model.
Embodiment
As Fig. 1, this low-temp radiating electrothermal membrane is made up of the electric heating layer of two translucent polyester films 3 and setting in the middle of it, electric heating layer is made up of heater 1 in parallel between two conductive strips 2 that be arranged in parallel and conductive strips, heater 1 is for being the resistor disc of continuous square-wave form on the electric heating layer plane, and conductive strips 2 and heater 1 are an overall structure.This low-temp radiating electrothermal membrane is simple in structure, and is easy to process, has higher bend resistance and tensile deformation ability, can guarantee the long-term normal steady operation of heater in parallel, and bend resistance and tensile deformation ability improve greatly.
