Carbon fiber far-infrared insulating device and far-infrared heating sheet

Abstract

The invention discloses a carbon fiber far-infrared thermal-insulation device and a far-infrared heating sheet. The carbon fiber far-infrared electronic health-care thermal-insulation device comprises an far-infrared heating sheet, a power source and a control unit, wherein the far-infrared heating sheet comprises an electrode lead, a copper foil electrode layer, a silver slurry layer and a carbon fiber layer; the copper foil electrode layer, the silver slurry layer and the carbon fiber layer are sequentially embedded in the nylon electric-insulation fibers and form thermocontact with each other; and the copper foil electrode layer is electrically connected with the power source and the control unit through the electrode lead. The silver slurry layer and the copper foil electrode layer which form thermocontact with the the carbon fibers, are connected with the power source so as to generate heat; and since the carbon fiber layer has high far-infrared radiation emissivity and high radiant heat conversion efficiency, the electric energy introduced by the electrode lead can be converted into heat energy to implement 1.5-400 micrometer wavelength far-infrared radiation heating. The experiment indicates that the heating efficiency of the far-infrared radiation heating is twice of common heat transfer. The far-infrared rays have favorable physiotherapeutic effect, and are applicable to human body thermal-insulation and health-care.

Description

technical field [0001] The invention relates to the field of electric heating technology, in particular to a carbon fiber far-infrared heating device and a far-infrared heating sheet. Background technique [0002] At present, sheet heaters are widely used in heat preservation devices such as heating mats, heating quilts, heating mattresses, heating blankets, and heating mats because they can easily control their heating temperature without making noise. Existing heat preservation devices with heating sheets generally use nickel-chromium alloy wires as a heating source, and the temperature distribution on the sheet heater containing nickel-chromium alloy wires is uneven, resulting in heating parts being limited to near the heating wires, and Nickel-chromium alloys have low emissivity of far-infrared radiation and low conversion efficiency of electrical energy into radiant heat, so they are not suitable for heating and healthcare applications of far-infrared radiation.

Problems solved by technology

Although this patent overcomes the defect that the electromagnetic wave generated by the heating of the AC point has side effects on the human body, the copper sheet is used as the heating sheet in this electric heating method, and the copper sheet has a low far-infrared radiation emissivity, so it is not suitable for far-infrared radiation.
