Description of the invention: [Technical field to which the invention pertains] The invention relates to a seed line heat source, and more particularly to a line heat source based on nanocarbon f. [Prior Art] Heat sources are important aspects of people's production, life, and scientific research. Line heat source is a kind of heat source, which has a wide range of applications in the field of jade industry, scientific research or life, such as electric heating tube, electric blanket, infrared therapeutic apparatus and electric heater. Ο

The prior line heat source generally includes a linear heating element (e.g., a resistance wire or the like) and two electrodes 'the two electrodes are spaced apart from each other and electrically connected to both ends of the linear heating element. When a voltage or an electric current is applied to the linear heating element through the two electrodes, the linear heating element generates Joule heat, and the heat is directly radiated outward at a normal wavelength. Usually, the linear heating element used as the line heat source is a heating wire made of metal, alloy or carbon fiber. However, the electric heating wire made of metal, alloy or carbon fiber has the following disadvantages: First, the heat generated by the electric heating wire is radiated outward at a common wavelength, and the electrothermal conversion efficiency is not high, which is not conducive to saving energy, and needs to be added to the adhesive. Cotton thread coated with far-infrared coating to improve electrothermal conversion efficiency. Second, the carbon fiber size is not small enough to be applied to a micro heat source, and when the wire diameter is small, the strength is low, it is easy to break, and it is not suitable for application to a micro heat source. Third, the quality of the heating wire is large, which is not conducive to the lightening of the heat source. In addition, the metal heating wire and the alloy heating wire are easily oxidized, and are often fatigued when bent or wound at a certain angle, so that the application thereof is limited.
