December 27th revised spring page, invention description: [Technical field of invention] [0001] The present invention relates to a surface heat source, and more particularly to a surface heat source based on a carbon nanotube. [Prior Art] [0002] Heat sources play an important role in people's production, life, and research. The surface heat source is a heat source, which is characterized in that the surface heat source has a planar structure, and the object to be heated is placed above the planar structure to heat the object, so that the surface heat source can simultaneously heat various parts of the object to be heated, and the heating surface is wide. Uniform heating and high efficiency. 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. Commercially available surface heat sources are usually electrothermally converted using a heating wire made of metal as a heating layer. However, the strength of the heating wire is not high and it is easy to break, especially when it is bent or folded into a certain angle, so the application is limited. In addition, the heat generated by the heating wire made of metal is radiated outward at a normal wavelength, and the electrothermal conversion efficiency is not high, which is disadvantageous for saving energy. [0004] The invention of non-metallic carbon fiber conductive materials has brought about a breakthrough in the development of surface heat sources. A heating layer using carbon fibers is usually coated with a water-repellent insulating layer on the outside of the carbon fibers as an electrothermal conversion element instead of the metal heating wire. Due to the good toughness of carbon fiber, this solves the electric heating to a certain extent. 097125371 Form No. A0101 Page 3 / 18 pages 1003483784-0 1360521 _. .100 years. December 27th, the shuttle is not replacing the strength of the wire. The shortcomings of breaking. However, since the carbon fiber is still radiated outward at a normal wavelength, the problem of low electrothermal conversion rate is not solved. In order to solve the above problems, the heating layer using carbon fiber generally comprises a plurality of carbon fiber heat source lines. The carbon fiber heat source line is a conductive twisted wire wrapped with a chemical fiber or a cotton thread. The outer surface of the chemical fiber or cotton thread is dip coated with a waterproof and flame-retardant insulating material. The conductive core wire is formed by winding a plurality of carbon fibers with a plurality of cotton threads coated with a far-infrared coating. The cotton wire coated with the far-infrared coating is added to the conductive core wire to enhance the strength of the core wire. Secondly, the heat generated by the carbon fiber after the energization can be radiated outward at the infrared wavelength. [0005] However, the use of carbon fiber paper as a heating layer has the following disadvantages: First, the carbon fiber strength is not large enough, the flexibility is not good enough, and it is easy to be broken, and it is necessary to add cotton wire to increase the strength of the carbon fiber, thereby limiting its proper range; second, the carbon fiber itself The electrothermal conversion efficiency is low, and the cotton wire coated with the far-infrared coating needs to be added to improve the electrothermal conversion efficiency, which is not suitable for energy conservation and environmental protection; thirdly, the carbon fiber heat source line needs to be first made into a heating layer, which is not conducive to large-area production. It is not conducive to the uniformity requirements, and at the same time, it is not conducive to the fabrication of micro-surface heat sources. [0006] In view of the above, it is necessary to provide a surface heat source with large strength, high electrothermal conversion efficiency, favorable energy saving, uniform heat generation, and controllable size, and can be made into a large area or a miniature surface. SUMMARY OF THE INVENTION [0007] A seed surface heat source includes a first electrode, a second electrode, and a heating layer. The first electrode and the second electrode are disposed on the heating layer at intervals and are in electrical contact with the heating layer. The heating layer comprises a carbon nanotube 097125371 Form No. A0101 Page 4 / 18 pages 1003483784-0 1360521 100 years. December Japan is replacing the ¥ layer, the carbon nanotube layer comprises a plurality of evenly distributed Carbon nanotubes. [0008] Compared with the prior art, the surface heat source has the following advantages: First, because the carbon nanotube has better strength and toughness, the strength of the carbon nanotube layer is larger, and the carbon nanotube layer is It is flexible and not easy to break, making it have a long service life. Secondly, the carbon nanotubes in the carbon nanotube layer are evenly distributed, the carbon nanotube layer has a uniform thickness and electrical resistance, the heat is uniform, and the electric heat conversion efficiency of the carbon nanotubes is high, so the heat source of the surface has a rapid temperature rise. The characteristics of small thermal hysteresis and fast heat exchange. Third, the diameter of the carbon nanotubes is small, so that the carbon nanotube layer has a small thickness, and a micro-surface heat source can be prepared for heating of the micro device. [Embodiment] Hereinafter, a surface heat source of the present technical solution will be described in detail with reference to the accompanying drawings. Referring to FIG. 1 and FIG. 2 , an embodiment of the present technical solution provides a surface heat source 10 . The surface heat source 10 includes a substrate 18 , a reflective layer 17 , a heating layer 16 , a first electrode 12 , and a first surface . The two electrodes 14 and an insulating protective layer 15. The reflective layer 17 is disposed on the surface of the substrate 18. The heating layer 16 is disposed on the surface of the reflective layer 17. The first electrode 12 and the second electrode 14 are disposed on the surface of the heating layer 16 and are in electrical contact with the heating layer 16 for flowing a current in the heating layer 16. The insulating protective layer 15 is disposed on the surface of the heating layer 16, and covers the first electrode 12 and the second electrode 14 for preventing the heating layer 16 from adsorbing external impurities. [0011] The substrate 18 is not limited in shape, and has a surface for supporting the heating layer 16 or the reflective layer 17. Preferably, the substrate 18 is a plate-like substrate, and the material thereof may be a hard material such as ceramics, glass, resin, quartz, etc. 097125371 may also be selected from flexible materials such as plastic or flexible fibers.

December 27th Shuttle Replacement Page When the section is used, the surface heat source 10 can be bent into any shape as needed. The size of the substrate 18 is not limited and can be changed according to actual needs. The preferred substrate 18 of this embodiment is a ceramic substrate. In addition, the substrate 18 in the surface heat source 10 is an optional structure when the heating layer 16 has a certain degree of self-supportingness and stability. [0012] The reflective layer 17 is arranged to reflect the heat generated by the heating layer 16, thereby controlling the direction of heating, for single-sided heating, and further increasing the heating rate. The material of the reflective layer 17 is a white insulating material such as: a food oxide, a metal salt or a ceramic. 5毫米。 In this embodiment, the thickness of the layer is 1 〇〇 micron ~ 0. 5 mm. The reflective layer 17< is formed on the surface of the substrate 18 by sputtering or other methods. It can be understood that the reflective layer 17 can also be disposed on the surface of the substrate μ away from the heating layer 16, that is, the substrate 18 is disposed between the heating layer 16 and the reflective layer I? to further strengthen the reflective layer 17 to reflect heat. The role. When the surface heat source 10 does not include the substrate 18, the heating layer 16 may be directly disposed on the surface of the reflective layer 17.
