Surface heat sources have been successfully used in industrial fields, scientific research fields or living areas, such as electric heaters, infrared therapeutic devices, and electric heaters. The front front heat source generally includes a heating layer and at least two electrodes disposed on a surface of the heating layer and electrically connected to a surface of the heating layer. When the electrode connected to the heating layer is supplied with a low voltage current, the heat is immediately released from the heating layer. The electrodes of the previous surface heat source are usually made of a metal piece, a wire, a metal film, an indium tin oxide (ITO) layer, a bismuth tin oxide (ITO) layer, a conductive silver paste layer or a conductive polymer layer. However, an electrode using a metal piece, a wire, a metal film, an indium tin oxide (I Τ 0 ) layer, a bismuth tin oxide layer, a conductive silver paste layer or a conductive polymer layer as a surface heat source has the following disadvantages: The electrode has a large resistivity, so the loss of electric energy is also large. Second, the electrode has poor flexibility and mechanical strength, long-term folding is easy to break, and the service life is short, which is not easy to apply to a flexible surface heat source. Third, the electrode has a large density, a large weight, and is inconvenient to use. 09713030#单单Α〇101 Page 3/18 pages 1013399292-0 1380732 101. October 18th nuclear replacement page [0004] In view of this, it provides a small electrode resistivity, flexibility and high mechanical strength Long-term folding is not easy to break, and the surface heat source with low density and light weight is really necessary. SUMMARY OF THE INVENTION [0005] A seed surface heat source includes a heating layer; and at least two electrodes, the at least two electrodes are spaced apart and electrically connected to the heating layer respectively; wherein the at least two electrodes are At least one of the electrodes includes a carbon nanotube structure.

Secondly, the excellent mechanical properties of the carbon nanotubes make the carbon nanotube structure have good flexibility and mechanical strength. Therefore, the use of a carbon nanotube structure as an electrode can correspondingly improve the surface heat source, especially the flexible surface.

The first electrode 12 and the second electrode 14 may be disposed on the surface of the heating layer 16 through a viscous or conductive adhesive (not shown) of the nanotube layer. The conductive adhesive can also better fix the first electrode 12 and the second electrode 14 on the surface of the carbon nanotube layer while achieving electrical contact between the first electrode 12 and the second electrode 14 and the carbon nanotube layer. The voltage applied to the heating layer 16 can be applied through the first electrode 12 and the second electrode 14. The first electrode 12 and the second electrode 14 are spaced apart from each other so that the heating layer 16 using the carbon nanotube layer is electrically connected to a certain resistance to avoid short-circuiting. Preferably, the first electrode 1013399292-0 09713030# single number A0101 page 6 / 18 pages 1387732 101. October 18 correction replacement page 12 and second electrode 14 are disposed on the surface of the heating layer 16, located in the heating Both ends of layer 16. [0013] At least one of the first electrode 12 and the second electrode 14 includes a carbon nanotube structure. The carbon nanotube structure is fixed to the surface of the heating layer 16 by a conductive adhesive or intermolecular force, and is electrically connected to the heating layer 16. The carbon nanotubes in the carbon nanotube structure include one or more of a single-walled carbon nanotube, a double-walled carbon nanotube, and a multi-walled carbon nanotube. This embodiment is preferably a metallic carbon nanotube.

[0017] The ordered carbon nanotube film may further comprise a plurality of parallel carbon nanotubes arranged in parallel. The long carbon nanotubes have a length of 1 cm to 5 cm and a diameter of 0.5 nm to 50 nm. Since the long carbon nanotube is a single carbon nanotube, its electrical resistance is smaller. Therefore, the ordered carbon nanotube film is used as an electrode, which can conduct current more effectively and reduce the loss of electric energy. [0018] When the carbon nanotube structure comprises at least two layers of ordered carbon nanotube film which are arranged in an overlapping manner When the 'adjacent ordered carbon nanotube film is tightly bonded by van der Waals force. Further, the number of layers of the ordered carbon nanotube film in the carbon nanotube structure is not limited, and the arrangement direction of the carbon nanotubes between the adjacent two ordered ordered carbon nanotube films forms an angle α. It can be prepared according to actual needs. Since the carbon nanotubes in the ordered carbon nanotube film are aligned in the same direction, they have excellent conductivity in the direction in which the carbon nanotubes are arranged. In this embodiment, the carbon nanotube structure can have excellent conductivity in all directions by changing the angle of intersection α between adjacent two ordered ordered carbon nanotube films. In this embodiment, the angle of intersection is preferred. α = 90 degrees. __单单单面面1 Page 8 of 18 pages 1013399292-0 1380732 [0019] October 18, 101 Nuclear replacement page When the carbon nanotube structure includes at least one nanometer carbon tube long line, The carbon nanotube long line is laid on the surface of the heating layer 16.

Referring to Figures 4 and 5, the long carbon nanotube line includes a plurality of carbon nanotubes connected end to end in a preferred orientation along the axial direction of the carbon nanotube long line. Specifically, the carbon nanotubes in the long line of the carbon nanotubes are arranged in parallel along the axial direction of the long line of the carbon nanotubes or spirally arranged in the axial direction of the long line of the carbon nanotubes. The carbon nanotubes in the long line of the carbon nanotubes are closely combined by the van der Waals force, so the long carbon nanotubes have a certain flexibility. The carbon nanotubes have a length of 200 to 900 microns. [0020] The carbon nanotube structure may further include a plurality of carbon nanotube long lines, and a plurality of carbon nanotube long lines intersect and overlap each other on the surface of the heating layer 16. The length, width and thickness of the carbon nanotube structure are not limited and can be prepared according to actual needs. Since the long carbon nanotube has a certain flexibility, the carbon nanotube structure can be bent and folded into any shape without breaking. [0021] Since the carbon nanotubes in the long carbon nanotube line are arranged along the longitudinal direction of the carbon nanotube long line, the carbon nanotube long line has a small electrical resistance along the length direction. Therefore, the long carbon nanotube wire is wound around the surface of the heating layer 16 as an electrode, which can effectively conduct current and save electrical energy. [0022] When only one electrode includes a carbon nanotube structure, the other electrode uses a metal sheet metal wire, a metal film or a conductive adhesive layer or the like. In this embodiment, preferably, the first electrode 12 and the second electrode 14 are both made of a carbon nanotube structure, and the carbon nanotube structure comprises 50 layers of ordered nano-09713030 Lu single number A0101 ninth overlapping and intersecting.

The ordered carbon nanotube film in the carbon nanotube structure has a length of 1 cm, a width of 1 cm, and a thickness of 30 μm. In this embodiment, two of the above-mentioned carbon nanotube structures are separately wrapped around the surface of the heating layer 16. Due to the good electrical conductivity of the carbon nanotube structure, a good electrical connection is formed between the carbon nanotube structure and the heating layer 16. [0023] In this embodiment, preferably, the heating layer 16 is a carbon nanotube layer. The first electrode 12 and the second electrode 14 are each formed by overlapping and intersecting 10 layers of ordered carbon nanotube film, and the angle between the adjacent two layers of ordered carbon nanotube film is 90 degrees. This structure can reduce the ohmic contact resistance between the heating layer 16 and the electrode, and improve the utilization of electric energy. [0024] When the surface heat source 10 of the embodiment of the present invention is in use, the first electrode 12 and the second electrode 14 of the surface heat source 10 may be connected to a power source and then connected to a power source. The carbon nanotube layer in the heat source 10 after the power is turned on can radiate electromagnetic waves of a certain wavelength range. The surface heat source 10 may be placed in direct contact with the surface of the object to be heated or at a certain distance from the object to be heated. [0025] The surface heat source has the following advantages: First, the carbon nanotube has excellent conductivity, so the resistance of the electrode is small, which is beneficial to reducing power consumption and improving heat generation efficiency. Second, the carbon nanotube The excellent mechanical properties make the carbon nanotube structure have good flexibility and mechanical strength. Therefore, the use of a carbon nanotube structure as an electrode can correspondingly improve the surface heat source, especially the durability of the flexible surface heat source. The surface heat source has a long service life; thirdly, the density of the carbon nanotubes is small, so the heat source of the surface is light in weight and convenient to use. In summary, the present invention has indeed met the requirements of the invention patent, and is stipulated in accordance with the law.
