Description of the invention: [Technical field of the invention] The surface of the invention relates to a surface heat source, in particular to a surface heat source based on a carbon nanotube. [Prior Art] Heat sources play an important role in people's production, life, and scientific research. :: A source heat source, characterized in that the surface heat source has a planar structure, ^ Temple plus, the object is placed above the planar structure to strengthen the object, honing: the various parts of the object to be heated are simultaneously heated, heated Face:, uniform and efficient. The surface heat source has been successfully used in industrial fields, = fields or living areas, such as electric heaters, infrared therapeutic devices, electric heating, helium, rain f:: heat sources generally include a heating layer and at least two electrodes, the electric = The enthalpy layer is released when it is placed on the surface of the heating layer and a low voltage current is applied to the electrode on the surface of the heating layer. Commercially available surface heat sources are now commonly used: as a heating layer for electrothermal conversion. However, the deer of the electric heating wire is broken, especially when it is bent or twisted into a fixed angle, so: U and U. In addition, the heat generated by the electric heating wire made of metal can be lighter than that of the electric heating conversion. The electrothermal conversion efficiency is not high, which is not conducive to saving. The invention of the carbon fiber conductive material has brought about the development of the surface heat source. ^ The heating layer of bismuth fiber is usually coated with a layer of carbon-proof electric heating element on the outside of the carbon fiber instead of the metal heating wire. Due to the good toughness, this solves the shortcomings of the electric heating wire strength 201008356 degree. 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 includes a plurality of carbon fiber heat source lines. The carbon fiber heat source line is a V-core wire wrapped with chemical fiber or cotton thread. The outer surface of the chemical fiber or cotton thread is dip coated with a waterproof flame-retardant insulating material. The conductive core wire is formed by winding a plurality of carbon fibers and a plurality of surfaces coated with a far red color. 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. However, the use of carbon fiber paper as the 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. It is necessary to add cotton wire to increase the strength of the carbon fiber, and limit its proper range; second, the electric heating of the carbon fiber The conversion efficiency is low, and it is necessary to add the cotton wire coated with the far-infrared coating to improve the electrothermal conversion efficiency, which is not conducive to energy conservation and environmental protection. Thirdly, the J fiber heat source line is further made into a heating layer, which is not conducive to large-area production, which is not conducive to = uniform I· The requirements of life' at the same time are not conducive to the production of micro-surface heat sources. ❾ There is a kind of surface heat source that has a high intensity and a high electrothermal conversion efficiency, and the source and the heat are all controllable, and can be made into a large area or a type of surface heat source. The invention provides a source 'which includes a substrate; a heating layer, the heating layer is a layer of electricity; at least two electrodes are spaced apart and respectively, and the heating layer includes a carbon nanotube layer The surface heat source of the "an s layer including a plurality of intertwined carbon nanotubes.

The direct transmission of the third 'nanocarbon tube is small, so that the reverse layer of the nano-stone has a small thickness, and a micro-surface heat source can be prepared for heating of the micro device. f [Embodiment] ❹ = the lower part will be attached The figure details the surface heat source of the technical solution.

In the case of the same area, the greater the thickness of the carbon nanotube layer, the slower the thermal response speed; conversely, the smaller the thickness of the carbon nanotube layer, the faster the thermal response speed. Including the intertwined carbon nanotubes, please refer to Fig. 3. The carbon nanotubes are attracted to each other by van der Waals force, and the network structure is formed. In the carbon nanotube layer, The carbon nanotubes are evenly distributed on the 9 201008356, and the irregular arrangement makes the nano The tube layer is isotropic; the carbon nanotubes are intertwined 'so the carbon nanotube layer has good flexibility' and can be bent into any shape without breaking, see Figure 4.

It is found by the second=falling instrument. The temperature of the surface heat source can reach 15 〇〇 or more, and _ will generate a common heat radiation. With the further increase of the power supply voltage, the heat source 10 can also generate rays (ultraviolet light) that are invisible to the human eye that kills the bacteria. It can be applied to the fields of light source, display device, etc. The surface heat source has the following advantages: ―, because the carbon nanotubes have a good (four) degree of juvenileness, the strength of the na(4)f layer is large, and the carbon nanotubes are too The flexibility is 'not easy to break, so it has a long service life. Second, the carbon nanotubes in the carbon nanotube layer are evenly distributed, the carbon nanotube layer has uniformity, ^ degree and resistance, and the heat is uniform. The carbon-carbon tube has high electrothermal conversion efficiency, so the source has the characteristics of rapid temperature rise, small heat lag, fast heat exchange rate, and light efficiency. Third, the diameter of the carbon nanotubes is small, so that the nano tube layer has a relatively thick thickness, and the micro surface (four) can be prepared for heating of the micro device. In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application in accordance with the law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application in this case. Equivalent modifications or variations made by persons in accordance with the spirit of the present invention are intended to be within the scope of the following claims. 13 201008356 [Simple Description of the Drawings] FIG. 1 is a schematic structural view of a surface heat source according to an embodiment of the present technical solution.
