Description of the Invention: [Technical Field of the 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 097 诵 single number should be 01 to some extent. 01 Page 3 / 18 pages 1013399288-0 1380731 On October 18, 101, the replacement of the filament is not high and easy to break. Shortcomings. 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 wires laid *. The fiber heat source line is a conductive core 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 and a plurality of cotton wires coated with a far-infrared coating. A cotton wire coated with a 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 directly emitted at an 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 it is necessary to add a cotton wire coated with far-infrared coating to improve the electrothermal conversion efficiency, which is not conducive to energy conservation and environmental protection. Third, it is necessary to first make a carbon fiber heat source line and then make a heating layer, which is disadvantageous for large-area production, which is disadvantageous. In order to meet the requirements of uniformity, it is not conducive to the fabrication of micro-surface heat sources. [0006] In view of this, it provides a high strength, high electrothermal conversion efficiency, energy saving, uniform heat generation, and controllable size. Large area or miniature surface heat sources are necessary. SUMMARY OF THE INVENTION [0007] A 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 single number deletion 1 page 4 / 18 pages 1013399288-0 Γ 380731. 1101. October layer, and the nanotube layer includes isotropic 'oriented in a fixed direction Or a plurality of carbon nanotubes arranged in a different orientation. Compared with the prior art, the surface heat source has the following advantages: First, the carbon nanotube can be conveniently fabricated into a carbon nanotube layer of any size, which can be applied to both macroscopic and microscopic applications. field. Second, the carbon nanotubes have a smaller density than the carbon fibers, so the surface heat source using the carbon nanotube layer has a lighter weight and is convenient to use. The third 'nanocarbon tube layer has high electrothermal conversion efficiency and low thermal resistance rate, so the surface heat source has the characteristics of rapid temperature rise, small heat lag, and fast heat exchange rate. The fourth carbon nanotube layer can be directly obtained by milling a carbon nanotube array, which is easy to prepare and low in cost. [Embodiment] [0009] The surface heat source of the present technical solution will be described in detail below with reference to the accompanying drawings. Referring to FIG. 1 and FIG. 2 , the embodiment of the present invention provides a surface heat source 10 including a substrate 18 , a reflective layer 17 , a heating layer 16 , a first electrode 12 , and a second surface . The electrode 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 spaced apart and electrically contacted with the heating layer 16 for flowing a current in the heating layer 16. The insulating protective layer 15 is disposed on a surface of the heating layer 16. And covering the first electrode 12 and the second electrode 14 for preventing the heating layer 16 from adsorbing external impurities. [0011] The number of the base 18 is not limited, and has a surface for supporting the heating layer 16 or the reflective layer 17. Preferably, the substrate 18 is a plate-shaped substrate, and the material thereof may be a hard material such as ceramic, glass, resin, quartz, etc., page 5 of 18 1013399288-0 1380731 --·~_ 101 years. On October 18th, the shuttle replacement page can also choose flexible materials such as plastic or flexible fiber. When it is a flexible material, the surface heat source 10 can be bent into any shape as needed during use. 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. [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 improving the efficiency of heating. The material of the reflective layer 17 is a white insulating material such as a metal oxide, a metal salt or a ceramic. 5毫米。 The thickness of the layer is from 100 microns to 0. 5 mm. The reflective layer 17 can be 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 18 away from the heating layer 16, that is, the substrate 18 is disposed between the heating layer 16 and the reflective layer 17, further enhancing the reflective layer 17 to reflect heat. effect. The reflective layer 17 is an alternative structure. The heating layer 16 can be directly disposed on the surface of the substrate 18, and the heating direction of the surface heat source 10 is not limited, and can be used for double-sided heating. [0013] The heating layer 16 includes a carbon nanotube layer, the carbon nanotube layer itself has a certain viscosity, can be disposed on the surface of the substrate 18 by its own viscosity, or can be disposed on the substrate by a bonding agent. The surface of 18. The binder is a silicone rubber. The length, width and thickness of the carbon nanotube layer are not limited and can be selected according to actual needs. [0014] The carbon nanotube layer comprises a uniformly distributed carbon nanotube. The carbon nanotubes in the carbon nanotube layer form an angle α with the surface of the carbon nanotube layer, wherein α is greater than or equal to zero degrees and less than or equal to 15 degrees (OS α $15°). Preferably, the carbon nanotubes in the carbon nanotube layer are parallel to the carbon nanotube layer, and the number of the carbon nanotubes is parallel to the number of the carbon nanotubes. Page 6/18 pages 1013399288-0 Γ380731. 101. October 18 The U layer of the U-shaped rabbit can be prepared by obstructing a carbon nanotube array. The carbon nanotubes in the carbon nanotube layer have different arrangement depending on the manner of the pressure. Specifically, the carbon nanotubes may be isotropically aligned; when in the same direction as f, the carbon nanotubes are preferentially oriented in different directions. See Figure 3 for the month; when the pressure is blocked in the same direction, the carbon nanotubes are arranged in a preferred orientation along a solid direction, see Figure 4. The carbon nanotubes in the carbon nanotube layer partially overlap. The carbon nanotubes in the carbon nanotube layer are attracted to each other by the van der Waals force, and are tightly bonded, so that the carbon nanotube layer has a good softness and can be bent and folded into an arbitrary shape without breaking. _] The carbon nanotube of the carbon nanotube layer comprises one or more of a single-walled carbon nanotube, a double-walled nanocarbon S, and a Nicholas carbon nanotube. The diameter of the single-walled carbon nanotube is 0.5 nm to 10 nm, and the diameter of the double-walled carbon nanotube is J 'Ding, and the diameter of the rice is not more than the diameter of the multi-walled carbon nanotube. ~ 5 〇 nano. The length of the carbon nanotubes is greater than 5G microns. The length of the carbon nanotubes is greater than 50 microns, and preferably, the length of the carbon nanotubes is from 2 to 9 microns. _] The area and thickness of the carbon nanotube layer are not limited, and can be selected according to actual needs. The area of the nanotube layer is related to the size of the substrate on which the carbon nanotube array is grown. The thickness of the carbon nanotube layer is related to the height of the carbon nanotube array and the pressure of the rolling, and may be from i micrometer to millimeter. It can be understood that the greater the twist of the nano-carbon array and the smaller the applied pressure, the greater the thickness of the prepared carbon nanotube layer; conversely, the smaller the height of the carbon nanotube array, the greater the applied pressure The smaller the thickness of the prepared carbon nanotube layer. It can be understood that the thermal response speed of the carbon nanotube layer is related to its thickness. In the case of the same area, the greater the thickness of the carbon nanotube layer, the more the heat response speed is fe.

The carbon nanotube layer has a length of 5 cm and the carbon nanotube layer has a width of 3 cm. The carbon nanotube layer is placed on the surface of the substrate 18 by the viscosity of the carbon nanotube layer itself. [0018] The first electrode 12 and the second electrode 14 are composed of a conductive material, and the shapes of the first electrode 12 and the first electrode 14 are not limited, and may be a conductive film, a metal piece or a metal lead. Preferably, the first The electrode 12 and the second electrode 14 are each a conductive film. The thickness of the conductive film is 0.5 nm to 1 μm.
