Problems solved by technology

Obviously, this top-bottom reverse functional structure design is not conducive to realizing the high performance of the electric-to-mid-infrared heater
[0019] Related literature reports in terms of physiotherapy [7-20, 24], personal thermal management [21-24; US7642489; US10457424; US2018 / 0320067] and military applications [US7313909] describe the emission and manipulation of infrared radiation required for these applications All of these devices have the problem that the band range and emissivity do not meet the mid-infrared specification. When the emitter is working, the temperature of the emitting surface is higher than 46°C, which may cause the risk of human skin being burned; some of the existing technologies use traditional infrared emission Devices [US8975604; US9249492] have disadvantages such as large volume and weight, and do not meet the market demand for mid-infrared emitting screen energy-saving heating and mid-infrared physiotherapy

Abstract

The invention provides a thermally-insulated packaging mid-infrared-emitting panel (TIMEP for short) for heating and physiotherapy and a preparation method thereof. The mid-infrared-emitting panel comprises a top surface covering layer, a first gas thermal insulation layer, a first mid-infrared transmitting plastic thermal insulation layer, a second gas thermal insulation layer, a second mid-infrared transmitting plastic thermal insulation layer, a third gas thermal insulation layer, a first electric insulation layer, an electric-to-mid-infrared emission film layer, a second electric insulation layer and a bottom surface covering layer which are sequentially arranged in a laminated mode, wherein the mid-infrared transmissivity of the top surface covering layer and the thermal insulation layer is greater than or equal to 90%, the bottom surface covering layer is thermally insulated, and the mid-infrared emissivity is less than or equal to 10%; and the material of the electric-to-mid-infrared emission film layer comprises a low-cost coal-based nano carbon plastic compound. The innovativeness of the TIMEP is derived from unusual combination of the quantifiable attributes, the defect of high energy consumption of hot air convection heating is overcome through high thermal insulation, electricity can be efficiently transmitted to a user by converting to mid-infrared rays, and comfortable warm feeling and mid-infrared physiotherapy effect are provided for the user.

Description

technical field [0001] The invention relates to mid-infrared optical engineering, thermal insulation engineering, indoor heating and energy-saving green engineering, infrared physiotherapy, nano-engineering and intelligent manufacturing technology, in particular to a heat-insulating and packaged mid-infrared emission screen for heating and physiotherapy and a preparation method thereof . [0002] technical background [0003] Human civilization is making continuous progress, but the current development model is unsustainable, because the rate of global energy consumption has far exceeded the rate of replenishment of global energy reserves, resulting in a crisis of energy exhaustion. Since the indoor energy consumption of buildings accounts for nearly 40% of global energy consumption, disruptive innovations to reduce indoor energy consumption are particularly important and urgent [1-5]. Room heating technology is based on the transfer of heat energy by objects through solid h...
