INSTRUCTIONS: 1. Field of the Invention The present invention relates to a surface heat source, and more particularly to a surface heat source based on a carbon nanotube. [Prior Art] Heat sources play an important role in people's production, life, and research. The surface heat source is a heat source, 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 Wide, uniform heating and high efficiency. The surface heat source has been successfully used in the industrial field, the field or the living area, etc., such as an electric heater, an infrared therapeutic apparatus, and an electric heating front surface heat source generally includes a heating layer and at least two electrodes, and the two electrodes are disposed at the The railing layer is connected to the electricity. ^ And when the surface of the heating layer φ :, the electrode on the layer is supplied with a low voltage current, the amount of enthalpy is immediately released from the heating layer. Nowadays, the commercially available surface enamel source usually adopts the electric heating wire made of 丽 as the heating layer for the electric 埶 conversion of the metal. It is easy to break, and the application is limited. In addition, it is based on the heat of the metal, and the energy of the ordinary wave Μ mi electric wire. The electric ',,, conversion efficiency is not conducive to saving the breakthrough of non-metallic carbon fiber conductive materials. A heating layer using carbon fibers is usually used as an element for electrothermal conversion instead of a metal heating wire. :: 201006299 . Carbon fiber has a good character, which solves the disadvantage of the electric wire being strong and not easy to break. 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 problem, 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 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 and flame-retardant insulating material. The conductive core wire is formed by winding a plurality of carbon fibers and a plurality of cotton threads coated with a far red ❹^ coating. A cotton wire coated with far-infrared coating 2 is added to the conductive core wire to enhance the strength of the core wire, and 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 a heating layer has the following disadvantages: carbon fiber strength is not large enough, flexibility is not good enough, easy to crack needs to be added, the line increases the strength of the carbon fiber, limits its due range; the second itself has low electrothermal conversion efficiency, Need to add adhesive coating, ', ', line to improve the efficiency of electrothermal conversion, is not conducive to energy-saving ring flute, "coating cotton is this clothing insurance, third, need to heat the heat source line to make a heating layer, is not conducive to large areas The production is not conducive to the requirement of uniformity, and is conducive to the production of micro-surface heat source. There is a kind of high-energy, high electrothermal conversion efficiency, which is conducive to energy saving and uniform heating, and the size is controllable. A miniature surface heat source is necessary. 面积 Area or [invention] - a surface heat source, the surface heat source includes a first electrode, a second electrode: an upper electrode and a second electrode are disposed at the same ",, layer electrical contact.

It has a long service life. The carbon nanotubes in the second 'linear carbon nanotube structure are uniformly distributed, so that the thickness is uniform and the resistance is uniform, and the heat transfer efficiency of the carbon nanotubes is high. Therefore, the heat source of the surface has rapid heating and thermal hysteresis. Small, hot father changes speed. Third, the diameter of the carbon nanotubes is small, so that the linear carbon nanotube structure has a small thickness, and a micro-surface heat source can be prepared for heating of the micro device. μ ' [Embodiment] Hereinafter, the surface heat source of the present invention will be described in detail with reference to the accompanying drawings.

When the area of the surface heat source 1 in the embodiment of the present embodiment is constant, the electromagnetic wave of different wavelength ranges can be radiated by adjusting the magnitude of the power supply voltage and the thickness of the layer 16 . When the magnitude of the power supply voltage is constant, the thickness of the heating layer 16 and the wavelength of the surface heat source 1 〇 radiate electromagnetic chopping are opposite. That is, when the power supply voltage is constant, the thicker the thickness of the heating layer 16, the shorter the wavelength of the electromagnetic wave radiated by the surface heat source 1 ,, the surface heat source 10 can generate a visible light heat radiation; the thinner the thickness of the heating layer 16 is, the surface heat source 10 The longer the wavelength of the radiated electromagnetic wave, the surface heat source i ◎ can generate an infrared heat radiation. When the thickness of the heating layer 16 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 1 。. That is, when the thickness of the heating layer 16 is constant, the larger the power source voltage is, the shorter the wavelength of the electromagnetic wave radiated by the surface heat source 1 ,, the surface heat source 1 〇 can generate a visible light heat radiation; the smaller the power source tile is, the smaller the surface heat source 1 〇 wheel The longer the wavelength of the electromagnetic wave is, the surface heat source 1 产生 can generate an infrared heat radiation. 13 201006299 • $m carbon f has good electrical conductivity and thermal stability, and as * - ideal black body structure, has a higher pure shot efficiency. The surface is exposed to an oxidizing gas or an atmosphere, wherein the thickness of the linear structure is 5 mm, and the electromagnetic wave of the surface can be radiated by the heat source at 10 volts to 3 volts. . The temperature of the surface heat source 10 is found to be 5 (rc~5〇〇t>c by a temperature meter. For an object of the f structure, the corresponding temperature is 20 (TC~45 generation^2 U people) Invisible hot shot (infrared), the heat and light shot at this time is the most stable, the most efficient. The heating element made of the linear carbon nanotube structure: can be applied to electric heaters, infrared therapeutic devices, Further, the surface heat source 10 in the embodiment of the present technical solution is placed in a device = 'by adjusting the power supply voltage at 80 volts to 150 volts, the surface heat is radiant, and the radiant wavelength is shorter.
