Mid-infrared-transmitting and heat-insulating packaging mid-infrared heat supply and physiotherapy roller shutter

Abstract

The invention provides a mid-infrared -transmitting and heat-insulating packaging mid-infrared heat supply and physiotherapy roller shutter. The roller shutter has the design of a laminated structure and comprises a top surface covering layer, a porous polyethylene heat insulation mid-infrared anti-puncture layer, an electric-to-mid-infrared emission film layer (emission source), a heat insulation layer and a bottom surface covering layer; the infrared radiation intensity in the top surface of the roller shutter reaches 70% or more of the intensity of an emission source, and the leakage radiation of the bottom surface is less than 10%; and the emission source (the mid-infrared emissivity is greater than or equal to 95%) is composed of a conductive nano-carbon plastic compound. The innovativeness of the roller shutter is derived from extraordinary combination of quantifiable attributes, the defect of high energy consumption of hot air convection heating is overcome by utilizing the high thermal insulation property of porous polyethylene, electricity is converted into mid-infrared to be efficiently transmitted to a user, the energy power density of infrared directional transmission to the user can be two times or more of the non-selective convection energy power density, the high mechanical performance can prevent the user from being burnt due to careless piercing of the heat insulation layer, and the roller shutter has durability, brings comfortable warm feeling to the user and has a long-term safe and reliable intermediate infrared physiotherapy practical effect.

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. [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 the global energy consumption, innovations that disruptively 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 heat conduction, heat convection and infrared radiation, the most common of which is to achieve room heating through hot air convection....

Problems solved by technology

Although this invention patent overcomes many defects in the above-mentioned industries, the fatal shortcoming of using a gas thermal insulation layer sandwiched between two layers of plastic film to make a heat-insulating mid-infrared emission screen is that the mechanical strength of the sandwich component is not enough to protect the user Burns due to inadvertent piercing of the interlayer, resulting in skin contact with the hot film inside the screen

In addition, the scientific basis of ZL202010847951.8 is to use mid-infrared-transmissive low-cost polyethylene to replace mid-infrared-opaque glass, so that traditional double / triple-glazed windows have the innovative features of light transmission and heat insulation, but ZL202010847951 .8 Thinking along the "double / triple glazed window" model will lead to the thinking of latecomers solidified on frame windows, which has limitations
