Description
Technical field
The utility model relates to a kind of Electric radiant Heating Film.
Background technology
Electric radiant Heating Film is primarily of conductive materials and film forming matter or film material composition.Different conductive materials and film forming matrix can form many kinds of Electric radiant Heating Film.Electric radiant Heating Film is paid attention to by people day by day, and obtains applying more and more widely, this is because its advantage of having many traditional electrical thermal elements incomparable.Electric radiant Heating Film mainly contains following Some features: 1, planar heating, the heat efficiency are high, energy saving.
Electric radiant Heating Film is facial heating material, and form thermal conductive surface to greatest extent with heated object, heat transfer resistance is little.During electrified regulation, heat can pass to heated object very soon, and because this mode of heating heat conductivity is good, so Electric radiant Heating Film self-temperature is very not high, rubescent, red-hot phenomenon is not had to produce, radiation heat loss is very little, therefore with the electric heating appliance that Electric radiant Heating Film is made, the heat efficiency is quite high, generally all more than 90%.And traditional heat point source due to area of dissipation little, other objects to be leaned on indirectly to conduct with heated object, in electric heating transfer process, the heat energy that electric energy produces can not pass to heated object very soon, cause heat on electric heating element too concentrated, element itself becomes red-hot very soon, and a big chunk of electric energy becomes luminous energy and scatters and disappears, and causes electric conversion efficiency lower.
2, the life-span is long, not fragile.
General electric heat source always uses under red-hot state, so be easy to produce oxidation, causes joint open circuit.And because contact-making surface is large, heat conduction fast during Electric radiant Heating Film work, so own temperature is lower, this improves self the problem of oxidation of electrothermal film material under electrified regulation state, extend useful life.
For organic electro-thermal films, its flexibility is fabulous, resistance to bending.The folding life-span of Electric radiant Heating Film is greater than 8000 times.This feature is again that heating wire can not be compared.So organic electro-thermal films is applicable to the product of the frequent bending fold of needs that heating wire can not be suitable for, as electric heating clothes, electric heating waistcloth, electric pad, electric heating enclose the products such as shoulder.
3, external form alternative is strong, applied widely.
Electric radiant Heating Film can do film-like, wire, tabular, can intercept different length and size as required, is fixed on heating object surface by methods such as cladding, stickup, windings.
4, processing technology is simple, cost is low.
The traditional electrical thermal elements such as heating wire, electrothermal tube, electric hot tray are replaced by Electric radiant Heating Film, the auxiliary spare parts such as mica sheet, asbestos board, stone or metal plate for standing a stove on as a precaution against fire, pipe can be saved, thus component structure is greatly simplified, and the simple weight of manufacturing process, thickness and cost can significantly reduce.On the other hand, the raw material of Electric radiant Heating Film are all general industry raw materials, with low cost.
5, the flames of anger, safe and reliable.
Electric radiant Heating Film does not produce naked light in electric heating transfer process.When electrothermal film heater be in be heated to 100 DEG C of boiling water states time, Electric radiant Heating Film can not burn butterfly paper, cotton, match, contacts with it and also can not ignite.Therefore Electric radiant Heating Film is well suited for some needs heating and thermal insulation, and don't allows the Code in Hazardous Special Locations of naked light to apply.
Electric radiant Heating Film is becoming the focus of people's research at present, and obtains applying more and more widely, and this Electric radiant Heating Film kind has positive temperature coefficient (PTC, Positive Temperature Coefficient) resistance, that is has temperature-limiting character.This characteristic is not available for common Electric radiant Heating Film, and this characteristic can avoid Electric radiant Heating Film to occur the phenomenon that localized hyperthermia burns.Also can not burnt by protection component when overvoltage, overcurrent appear in electric network source.
See Fig. 1, at present, modal Electric radiant Heating Film comprises diaphragm 100, diaphragm 100 is printed with two trunk wires 101,102 and is connected to the branch line 103,104 on these two trunk wires 101,102.PTC conductive ink layer is main body heating resistor, has auto-temperature-limiting character, and silver-colored line is the electrical current carriers of circuit, when PTC electrically conductive ink sheet resistivity is certain, and the structures shape of the silver-colored line heating power of Electric radiant Heating Film (overall parallel resistance).Due to PTC electrically conductive ink sheet resistance usually comparatively large (1K/more than), when designing Electric radiant Heating Film circuit, often need silver-colored line parallel to reduce the resistance of overall calandria, when being especially applied to the 6-36V power supply people's livelihood that is the energy and industrial goods, a lot of silver-colored lines is needed to form parallel circuits, Fig. 1 is the silver-colored line design circuit that a typical PTC electrically conductive ink is applied to low-tension supply, supply voltage is 24V, heated by electrothermal film power 60W, PTC electrically conductive ink covers whole silver-colored line circuit region, its sheet resistance 5K/, there is following major defect in this design: 1, the trunk silver line on both sides needs the electric current carrying whole circuit, need very wide silver-colored line, and two the first conductors and the second conductor need to run through whole Electric radiant Heating Film length, silver-colored line is caused to account for whole Electric radiant Heating Film Area comparison very large (40%), the silver slurry consumed is a lot, considerably increase the cost of Electric radiant Heating Film, limit the scope of application of Electric radiant Heating Film, 2, the heating power at each position of Electric radiant Heating Film is not easy to regulate, easily there is local overheating phenomenon, because the heat radiation speed at each position of whole diaphragm is variant, this design there will be diaphragm central part superheating phenomenon usually, easily causes Electric radiant Heating Film high temperature to burn.
Summary of the invention
The utility model, for deficiency of the prior art, provides a kind of Electric radiant Heating Film, and its circuit can reduce silver slurry consumption, reduce Electric radiant Heating Film cost, and the convenient heating power regulating each position of electrothermal film, make each spot temperature of whole electrothermal film even, avoid occurring local overheating phenomenon.
For solving the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of Electric radiant Heating Film, comprise diaphragm, described diaphragm is provided with two backbones, two described backbones are connected with the branch line that electrocondution slurry is printed as, described branch line interval is arranged, and two adjacent branch lines are connected respectively at different backbones, and described branch line is that annular is arranged.This design can shorten the length of backbone on the one hand, reduces silver slurry consumption.Be convenient to the local heating capacity regulating each position of electrothermal film on the other hand, make each spot temperature of whole loop even.
