[Prior Art] [0002] Heat _ plays an important role in people's production, life, and scientific 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. Since the carbon fiber has better toughness, this solves the electric heating to a certain extent. 09713_(P No. 01, page 3/17 pages, 1013399290-0, 1380730, October 18, 101, the nuclear replacement is not high. The disadvantage of breaking. However, since the carbon fiber is still radiated outward at a common wavelength, the problem of low electrothermal conversion rate is not solved. To solve the above problem, the heating layer using carbon fiber generally includes a plurality of carbon fiber heat source lines. The carbon fiber heat source line is a conductive and durable wire wrapped with chemical fiber or cotton wire. The outer surface of the chemical fiber or cotton wire is dip coated with a waterproof flame-retardant insulating material. The conductive core wire is coated with a plurality of carbon fibers and a plurality of surfaces coated with far-infrared paint. The cotton thread is wound. The cotton wire coated with the far-infrared coating is added to the conductive core wire to enhance the strength of the core wire, and the heat emitted 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 is not strong enough, the flexibility is not good enough, it is easy to break, and it is necessary to add cotton. The strength of high carbon fiber limits its proper range; secondly, the carbon fiber itself has low electrothermal conversion efficiency, and it is necessary to add a cotton wire coated with far infrared paint to improve the electrothermal conversion efficiency, which is not conducive to energy conservation and environmental protection; The carbon fiber heat source line is further formed into a heating layer, which is not conducive to large-area production, which is not conducive to the uniformity requirement, and is not conducive to the fabrication of the micro-surface heat source. [0006] In view of this, it is provided that the strength is large and the electrothermal conversion efficiency is higher. High, conducive to energy saving and uniform heating, controllable size, can be made into a large area or micro surface heat source. [Summary] [0007] - a surface heat source, comprising: a substrate; a heating layer, The heating layer is disposed on a surface of the substrate; at least two electrodes are spaced apart and electrically contacted with the heating layer respectively, wherein the heating layer comprises a carbon nanotube layer, and the _3〇3# single number A〇101 Page 4 of 17 Page 1013399290-0 1380730 101. October 18th The nuclear replacement sheet carbon nanotube layer comprises a plurality of intertwined carbon nanotubes. [0008] Compared with the prior art, The surface heat source has the following advantages: First, the carbon nanotubes in the carbon nanotube layer are disorderly arranged, have good toughness, can be bent and folded into any shape without cracking, and thus 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 surface heat source has a rapid temperature rise. The thermal hysteresis is small and the heat exchange speed is fast. 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] [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 from each other and are in electrical contact with the heating layer 16 for flowing a current through 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 to prevent 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-shaped substrate, and the material thereof may be a hard material such as ceramics, glass, resin, quartz, etc., and a flexible material such as plastic or flexible fiber may also be selected.

October 18th to verify the replacement page material, the surface heat source 10 can be bent as needed during use The shape of the substrate 18 is not limited, and may be changed according to actual needs. The preferred substrate 18 of the present embodiment is a ceramic substrate. [0012] The reflective layer 17 is provided for reflecting the heating layer 16 The heat, 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: metal oxide, metal salt or ceramic, etc. This embodiment The reflective layer 17 is a layer of aluminum oxide having a thickness of 100 μm to 0.5 mm. The reflective layer 17 may be formed on the surface of the substrate 18 by sputtering or other methods. It is understood that the reflective layer 17 may also be The substrate 18 is disposed away from the surface of the heating layer 16, that is, the substrate 18 is disposed between the heating layer 16 and the reflective layer 17, further enhancing the effect of the reflective layer 17 reflecting heat. The reflective layer 17 is a The structure chosen. 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 is disposed on the surface of the substrate 18 for heating. The heating layer 16 includes a carbon nanotube layer which itself has a certain viscosity and can be disposed on the surface of the substrate 18 by its own adhesiveness, or can be disposed on the surface of the substrate 18 by a bonding agent. The bonding agent is tannin. The length, width and thickness of the carbon nanotube layer are not limited, and can be selected according to actual needs. The length of the carbon nanotube layer provided by the technical solution is 1 to 10 cm, and the width is 10 cm, thickness is 1 micron to 2 mm. 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 slower the thermal response speed; Conversely, the smaller the thickness of the carbon nanotube layer, the faster the thermal response speed. 0971303 (^单单 A0101 page 6 / page 17 1013399290-0 1380730 month 18 nuclear replacement & page [0014] The nanotube layer includes intertwined carbon nanotubes Please refer to Figure 3.

Or, since the nanotube in the carbon nanotube layer as the heating layer 16 in the embodiment has good electrical conductivity, and the carbon nanotube layer itself has a certain self-supporting property and stability, The surface heat source 20 can be disposed at a certain distance from the object to be heated. [0022] The surface heat source 1 in the embodiment of the present invention can radiate electromagnetic waves of different wavelength ranges by adjusting the magnitude of the power supply voltage and the thickness of the carbon nanotube layer when the area of the carbon nanotube layer is constant. When the power supply voltage is constant, the thickness of the carbon nanotube layer is inversely proportional to the wavelength of the electromagnetic wave radiated from the surface heat source. That is, when the power supply is of a certain size, the thicker the thickness of the carbon nanotube layer, the shorter the wavelength of the electromagnetic wave radiated from the surface heat source 10, the heat source of the surface can generate a visible light heat ray; the thickness of the carbon nanotube layer The thinner the surface, the longer the wavelength of the electromagnetic wave radiated by the surface heat source 10'. The surface heat source 10 generates an infrared heat radiation. When the thickness of the carbon nanotube layer is constant, the magnitude of the power supply voltage is inversely proportional to the wavelength of the electromagnetic wave radiated from the surface heat source 10. That is, when the thickness of the nano tube breaking layer is constant, the larger the power source voltage is, the shorter the wavelength of the electromagnetic wave radiated by the surface heat source 10 is, the surface heat source 1 〇 can generate a visible light heat radiation; the smaller the power source voltage, the surface heat source 10 is radiated. The longer the wavelength of the electromagnetic wave, the surface heat source 1 〇 can generate an infrared thermal ray. 09713030 (^ Single No. A0101 Page 9 / Total 17 Page 1013399290-0 1380730 October 18, 2011 Shuttle replacement page [0023] Nano carbon tube has good electrical conductivity and thermal stability, and as an ideal black body The structure has a relatively high heat radiation efficiency. The surface heat source 10 is exposed to an oxidizing gas or an atmosphere, wherein the thickness of the carbon nanotube layer is 5 mm, and the power supply voltage is adjusted by 10 volts to 30 volts. The surface heat source 10 can radiate electromagnetic waves having a long wavelength. The temperature of the surface heat source 10 is found to be 50 ° C to 500 ° C by a temperature measuring instrument. For an object having a black body structure, the corresponding temperature is 200 ° C. At ~450 °C, it can emit heat radiation (infrared) that is invisible to the human eye. At this time, the heat radiation is the most stable and efficient. The heating element made of the carbon nanotube layer can be applied to electric heaters and infrared. Further, the surface heat source 10 in the embodiment of the present technical solution is placed in a vacuum device, and the surface heat source 10 can be radiated by adjusting the power supply voltage at 80 volts to 150 volts. Shorter wavelength When the power supply voltage is greater than 150 volts, the surface heat source 10 will emit visible light such as red light and yellow light. The temperature of the surface heat source 10 can reach above 1 500 ° C by a temperature measuring instrument, and an ordinary one is generated. Thermal radiation. As the power supply voltage is further increased, the surface heat source 10 can also generate rays (ultraviolet light) that are invisible to the human eye that can kill bacteria, and can be applied to fields such as light sources, display devices, and the like. The heat source has the following advantages: First, since the carbon nanotube has good strength and toughness, the strength of the carbon nanotube layer is large, and the carbon nanotube layer has good flexibility and is not easily broken, so that it has a long use. Second, 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 electrothermal conversion efficiency of the carbon nanotube is high, so the surface heat source has a temperature rise. Rapid, low thermal hysteresis, fast heat exchange rate, high radiation efficiency.
