A far infrared heating sheet

Abstract

A far infrared heating sheet is mainly composed of a metal layer and a radiant heat sink layer, the metal layer is in close contact with a substrate that requires heat dissipation, the heat of the substrate can be quickly transferred to the metal layer, the metal layer can rapidly distribute heat conducted by the substrate over the entire surface of the metal layer, the metal layer conducts its own heat to the radiating layer, As that radiant heat dissipate layer has the heat energy-far infrared conversion function, the radiant heat sink converts the heat it absorbs into far-infrared radiationinto air, the radiant heat sink layer must consume heat to radiate far infrared ray, so it will consume heat of radiating radiating layer continuously, so it can speed up heat conduction from metal layer to radiating radiating layer, because heat of matrix will be transferred to metal layer quickly, heat of matrix will be consumed continuously, so as to achieve the purpose of reducing temperatureof matrix.

Description

technical field [0001] The invention relates to an electric heating sheet driven by alternating current or direct current. The heating sheet completes the conversion of electric energy to thermal energy and far infrared rays. The heating sheet also radiates far infrared rays to space while generating heat. The technology belongs to the technical field of far infrared radiation heating . Background technique [0002] In terms of heating products such as electric blankets, physical therapy health care, and thermal clothing, the heating source uses metal heating wires. When the metal heating wires are heated, there is uneven heating, and the electrothermal conversion efficiency is relatively low. Users can feel the existence of the metal heating wires. , the temperature of the position with metal heating wire is relatively high, and the temperature of position without metal heating wire is relatively low. If it is an electric blanket, the user will feel the existence of a metal...

Problems solved by technology

[0003] In order to overcome the problem that the far-infrared rays radiated by existing far-infrared heating products cannot effectively irradiate the surface of the object to be acted on, and the heating sources used in electric blankets, physical therapy and health care products, and thermal clothing heating products exist in use, the present invention provides a far-infrared heating device. The core components of a far-infrared heating sheet are a heating layer, a decorative layer, and a radiation far-infrared source. The heating layer is driven by AC or DC voltage. The heating layer is closely connected with the radiation far-infrared source through the decorative layer. It is directly transmitted to the radiation far-infrared source. The particles of the radiation far-infrared source are embedded in the pores of the decorative layer and together with the far-infrared layer above the decorative layer constitute a radiation far-infrared source. There is no shield on the surface of the radiation far-infrared source. The far-infrared rays produced by the far-infrared ray source can directly irradiate the surface of the heated object, which avoids the problem that the far-infrared rays produced by the radiation source are blocked by the object and consume a part of the far-infrared rays before they irradiate the object to be acted on; The source is a plane, and every point of the entire plane is radiating far-infrared rays, which ensures the uniformity of far-infrared rays irradiating the surface of the object to be acted upon.
