The content of the invention
Good it is an object of the invention to overcome the deficiencies of the prior art and provide a kind of heating effect, pliability is good, pliableFolding, convenient disassembly, the electric heating electro-heat equipment of service life length.
In order to achieve the above object, a kind of electric heating electro-heat equipment designed by the present invention, it include two protective layers, twoGlue-line, heating layer；Described heating layer is arranged between two glue-lines, and heating layer, which is covered by, wherein forms enclosed construction；One group of power connection points is respectively provided with the diagonal position of heating layer, this group of power connection points are that positive pole tie point and negative pole are connectedPoint, one group of described power connection points are connected by wire with power supply；A protection is respectively equipped with outside two glue-linesThe edge of layer, the first protective layer and the second protective layer is adhesively-bonded together to form enclosed construction；The protective layer, heating layer are by softProperty material constitute, heating layer includes carbon nano-tube film, electrode slice, and electrode slice has two and non-intersect, and two strip electrode pieces pass throughAt least one carbon nano-tube film is connected；Described power connection points are the contact point of wire and electrode slice.
Electric heating electro-heat equipment described above is to use direct current, or alternating current is converted to DC current, preferably makesWith low-voltage, such harm to the human body is small, safety.
The thickness range of described carbon nano-tube film is most preferably not more than 100 μm.
In order to increase the contact area of electrode slice and heating layer, the connected mode of electrode slice and carbon nano-tube film can beCarbon nano-tube film is clamped after monolithic electrode piece doubling, can also set two panels electrode slice is two-sided to clamp carbon nano-tube film, orPerson will wrap up electrode slice after carbon nano-tube film doubling, and the upper and lower surface and carbon nano-tube film for making electrode slice contact connection.
In order to strengthen cleanliness factor, reducing heating layer contact dust or reduce the degree of oxidation of heating layer, and cause twoGood sealing state is formed between protective layer, is bonded between heating layer, glue-line and protective layer by hot pressing ironing process, first protectsBy heat pressure adhesive between the edge of sheath and the second protective layer, make sealing effectiveness more preferable.
The protective layer material can be lining cloth or hot melt adhesive film.The glue-line is the double faced adhesive tape of strip substrate, can be PETDouble faced adhesive tape.
In order to strengthen the electrical conductivity of electrode slice and carbon nano-tube film contact position, electrode slice is received with carbon by metal rivetMitron film is fixedly connected, and is either carried out suture connection with metal wire or is carried out bonding connection, Huo Zheyong with conducting resinlTin cream carries out pressing connection.The electrode slice can be that the materials such as copper foil, conductive fabric, silver paste are constituted.
Above-mentioned electric heating electro-heat equipment can be connected in device circuitry with monolithic or multi-disc is connected in series or multi-disc parallel connection connectsConnect.
The electric heating electro-heat equipment of the present invention is produced in use, heater body is placed in into clothes, protector, bedding, electronicsProduct etc., wire is placed in outside product, carbon nano-tube film is produced heat energy, the heat of generation by electrode slice conduction after switching on powerThe protective layer of outside can be further transferred to.
The present invention is using carbon nano-tube film as exothermic material, and carbon nano-tube film has good chemical stability,High heat conductance, good mechanical property and gas-permeable conductive, CNT are best Heat Conduction Materials in the world at present, by remoteInfrared transferring heat energy；Meanwhile, carbon nano-tube film pliability is good, resistant to bending, meets the bending such as electric heating product and elbow, knee, neckThe laminating in portion is used, and repeatedly folding will not also produce the phenomenons such as cracking destruction for a long time, extend the use longevity of heaterLife.
Power connection points are diagonally accessed heater by the present invention, make heating more uniform；And by increase electrode slice withThe adhesive seal between electrical conductivity and exothermic material and protective layer at contact area between exothermic material, contact-enhancingDegree, solves the problems, such as the contact resistance between part well, it is produced more preferable heating effect.
