Detailed Description
Unless otherwise defined, technical or scientific terms used herein shall have the ordinary meaning as is understood by those of ordinary skill in the art to which the invention belongs. All numerical values recited herein as between the lowest value and the highest value are intended to mean all values between the lowest value and the highest value in increments of one unit when there is more than two units difference between the lowest value and the highest value.
In the following description of the embodiments of the present invention, with reference to the drawings, it is noted that in the detailed description of the embodiments, all features of the actual embodiments may not be described in detail in order to make the description concise and concise. Modifications and substitutions may be made to the embodiments of the present invention by those skilled in the art without departing from the spirit and scope of the invention, and the resulting embodiments are within the scope of the invention.
The traditional electric heating device is beautified by packaging and printing patterns, but thermal imaging cannot be realized. The purpose of the application is to provide a thermal imaging patterned electric heating device, which comprises a heating layer and a protective layer, wherein the heating layer is a thermal imaging patterned heating layer; and/or the protective layer is a thermal imaging patterning protective layer. The protective layer is positioned on two sides or one side of the heating layer, and the main function of the protective layer is to protect the heating layer or enable the heat generated by the heating layer to have a thermal imaging patterning function. Preferably on both sides of the heat generating layer.
In one embodiment, the thermal imaging patterned heating layer is a heating layer that self-heats when energized to form a thermal imaging pattern, i.e. a thermal imaging patterned electrothermal layer, and the protective layer is a uniform protective layer.
In one embodiment, the thermal imaging patterned heating layer is a thermal imaging patterned electrothermal layer, and the protective layer is a thermal imaging patterned protective layer, and better thermal imaging effect can be obtained by using the thermal imaging patterned electrothermal layer and the thermal imaging patterned protective layer simultaneously.
In one embodiment, the thermal imaging patterned heat-generating layer comprises one or more of a combination of a full-coverage type, a stripe type and a hollow type. Wherein, the thickness of the full-coverage thermal imaging patterning heating layer is not completely the same; the thickness and/or the width of the heating lines at different parts in the stripe-type or hollow-out-type thermal imaging patterning heating layer are not all the same. Since three different types of thermal imaging patterned heat-generating layers have different effects on the design of the thermal imaging pattern, it is relatively simple to use a single type in design, but for complex requirements, a combination of multiple types of images can also be used.
In one embodiment, the self-heating heat-generating layer forming the thermal imaging pattern is prepared by one or more of coating, printing, electroplating, metal etching and evaporation. The obtained heating layer is a coating or a plating layer, the coating or the plating layer belongs to surface heating, the processing technology is simple, the effect design can be realized by using the existing equipment, and the capital investment of secondary equipment is reduced.
In one embodiment, the process for forming the thermal imaging pattern by self-heating is preferably coating or printing, which is more cost effective and efficient.
In one embodiment, the uniform protective layer comprises one or more of a combination of a uniform insulating layer, and a uniform heat dissipation layer. The heat dissipation layer has the main function of dissipating heat generated by the heating layer; the insulating layer has the main function of isolating the current passed by the heating layer; the main function of the heat-insulating layer is to prevent the heat generated by the heat-generating layer from being dissipated.
In one embodiment, the uniform heat dissipation layer is a commercially available general heat dissipation layer material, specifically one or more of a heat dissipation coating, a heat dissipation film, a heat dissipation sheet, and a heat dissipation plate. The heat dissipation device is characterized in that the areas have approximately the same heat dissipation capacity, specifically, the areas have the same specific surface area or the same thermal radiation coefficient, so that the comprehensive heat dissipation capacity is the same.
In a specific embodiment, the uniform insulating layer is a general insulating layer material available on the market, and specifically is one or more of an insulating coating, an insulating film, an insulating sheet and an insulating board. The heat conduction plate is characterized in that the areas have approximately the same heat conduction capability, specifically, the areas have the same thickness or the same heat conduction coefficient, so that the comprehensive heat conduction capability is the same.
In one embodiment, the heat generating layer is a heat generating layer that generates heat uniformly, and the protective layer is a thermal imaging patterning protective layer.
In one embodiment, the thermally imaged patterned protective layer comprises at least one of a thermally imaged patterned insulating layer and a thermally imaged patterned heat sink layer.
In one embodiment, at least two heat dissipation areas with different heat dissipation capabilities are disposed in the thermal imaging patterned heat dissipation layer. Specifically, the heat dissipation areas with different heat dissipation capacities are areas with different comprehensive heat dissipation capacities, and the areas are composed of at least one of materials with different specific surface areas and different emissivity coefficients.
In one embodiment, the thermal imaging patterned insulation layer has at least two insulation regions with different insulation capabilities. Specifically, the heat-insulating regions with different heat-insulating capacities are regions with different comprehensive heat-conducting capacities, which are formed by at least one of materials with different thicknesses and different heat-conducting coefficients.
In a specific embodiment, the protective layer further comprises an insulating layer.
In a specific embodiment, the heat dissipation layer, the insulating layer and the heat insulation layer are one or more combinations of different layers and/or the same layer. Because some materials with special materials or special structures can have the effects of heat dissipation and insulation or the effects of heat preservation and insulation. Therefore, the heat dissipation layer, the insulating layer and the heat insulation layer can be independent structures or can be combined by multiple layers. In view of the convenience of processing, a multi-layer structure is preferable.
In a specific embodiment, the material of the heat generating layer includes one of a metal material or an inorganic non-metal material, the inorganic non-metal material includes one or more of a carbon material, an infrared ceramic and a tourmaline material, and preferably, the material of the heat generating layer is a carbon material.
In one embodiment, the metallic material comprises a powder, slurry or plating stock made from one or more of copper, aluminum, iron and nickel.
In one embodiment, the carbonaceous material comprises a powder or slurry made from one or more of graphite, conductive carbon black, carbon crystals, carbon nanotubes, carbon fibers, graphene, and fullerenes. Since thermal imaging is mainly generated by infrared radiation, carbon materials are the preferred scheme for the material of the heating layer in combination with the conductive capability and the infrared radiation capability.
In one embodiment, the infrared ceramic and the tourmaline material are powder or slurry.
In a specific embodiment, the electric heating device of the present invention can be any commercially available form, and is preferably one or a combination of more of an electric heating coating, an electric heating cloth, an electric heating paper, an electric heating film, an electric heating plate, and an electric heating block. In consideration of convenience of use, one or a combination of more of an electric heating cloth, an electric heating paper, an electric heating film, and an electric heating plate is preferable.
