Description of the Invention: [Technical Field] The present invention provides an aluminum plate heating structure, and more particularly to a heating plate structure capable of reducing power consumption. [Prior Art] According to the electric heating elements, which are more common and commonly used today, the heating wire 1, the electric heating tube 2 and the metal electric heating plate 3 shown in Fig. φ are widely used in a wide range of applications from industry to people's livelihood. Transportation to medical aspects, such as heaters, hot air blowers, ovens, water dispensers, electric blankets, incubators, warm mats, defogging devices, automotive electric heaters and electric heaters, etc., and heating wires i, electric heating tubes 2 and The metal electric heating plate 3 utilizes the electric resistance coefficient of the conductive material itself. Therefore, after the electric current is applied, the material itself generates heat due to the heat generated by the electric resistance for the application of the human body. In order to obtain accurate thermal energy, it is necessary to accurately calculate the material. Characteristics, and according to the calculation results, accurately produce a certain material, a certain length of production, a certain cross-sectional area of the heating wire, 1, electric heating tube 2 and metal electric heating = 3, but due to the material itself, it is difficult to make energy Accurately radiating a fixed amount of electric heating elements, and further, since the electric heating wire amp &, the electric heating tube 2 and the metal electric heating plate 3 have high resistance values, they are very expensive to use. Force. Therefore, how to eliminate the above problems, the loss of the case is the technical difficulties that the 201110800 people want to solve. SUMMARY OF THE INVENTION Therefore, the inventors of the present invention have invented such inventions in view of the above-mentioned deficiencies, collected relevant materials, evaluated and considered through various parties, and accumulated years of experience in the industry, through continuous trials and revisions. Patent holder. The main purpose of the present invention is that it mainly consists of a substrate, at least one electric heating layer and two conductive layers. After the conductive layer is turned on, the electric heating layer emits heat and conducts to the substrate, thereby making the substrate usable. Thermal energy, and because the electrothermal layer is mainly made of a mixture of graphite and tantalum, the conductive layer can be quickly heated, reduced in power consumption, and increased in service life. The secondary object of the present invention is that since the arrangement structure of the electrothermal layer can achieve the thermal conductivity of the crucible, the electrothermal layer only needs to be applied to the substrate in a partial manner without completely coating the surface of the substrate, so that sufficient heat energy can be generated. In order to achieve the purpose of reducing production costs. [Embodiment] In order to achieve the above objects and effects, the technical means and the structure of the present invention will be described in detail with reference to the preferred embodiments of the present invention, and the features and functions are as follows. Please refer to the second, third, fourth, fifth and sixth figures, which are schematic diagrams, perspective exploded views, schematic diagrams of sections 201110800, sectional views and preferred embodiments of the present invention. As is clear from the figure, the structure of the present invention is mainly composed of a substrate 4 of a material, at least an electrothermal layer 5, and a conductive layer 6 made of a silver-containing knee material. The layer 5 is mainly made of a mixed material of graphite and dream, wherein the content of graphite in the mixed material is at least 8 〇% or more, and the others are hair. The electric heating layer 5 of the present invention uses a mixed material of graphite and stone eve. However, graphite has good electrical conductivity, thermal conductivity, heat, and is not easily oxidized, not affected by any acid and high melting point. Shi Xi has the characteristics of very stable chemical properties and small thermal expansion coefficient. In terms of setting, the electrothermal layer 5 is mainly applied to a partial surface of the substrate 4, and the two conductive layers 6 are respectively applied to the two ends of the electrothermal layer 5, and the surface of the electrothermal layer 5 is coated with a resin material. The edge layer 7, when in use, conducts current from the conductive layer 6 applied to both ends of the electrothermal layer 5, so that the electrothermal layer 5 emits heat and conducts heat to the substrate 4, so that the substrate 4 can be used. The thermal energy, and the insulating layer 7 coated on the surface of the electric heating layer 5, mainly prevents the current of the conductive layer 6 from breaking down the electric heating layer 5 after the current is turned on; and, please refer to the seventh and eighth figures. It is a further embodiment of the present invention. As is clear from the figure, since the arrangement structure of the electrothermal layer 5 of the present invention can achieve high thermal conductivity, the electrothermal layer 5 does not need to be applied to the substrate 4 to conduct current. Coating the entire substrate 4 201110800 The surface 'only need to apply a local block to generate enough heat, so it can be coated into a square, rectangular, circular or irregular shape according to the use requirements, thereby greatly reducing the production. The cost of the electric heating layer 5; and the electrothermal plate used in the present invention and the conventional use, in the same environment and the purpose to be achieved, the experiment is carried out to obtain various data values than the experimental method mainly in two stainless steel bowls respectively. Pour 5 〇CC about 5 8 C, and place the creation and custom electric heating plates on the bottom of the two stainless steel bowls. Use DC to energize the creation and the conventional electric heating plate, and continue to heat the coffee in the stainless steel bowl. Keep the coffee at 5 Οΐ for about 1 , minutes and measure the following voltage and current data: '
