Solution details

Vacuum Insulation Panel (VIP Panel for short) adopts the principle of micro-nano-scale vacuum insulation of porous media and is composed of filled core materials, high polyester-based films, gas adsorption materials, etc. This technology is based on the rarefied gas effect in the free molecular domain, studies the correlation between mesoscale material physical properties and thermal insulation properties, and develops core materials such as ultra-fine fibers, nanopores, and foams; based on numerical analysis of the edge thermal bridge effect, a thermal analysis model is constructed to deeply analyze the molecular thermal transport mechanism, based on alternating temperature aging data, coupled with the penetration of gas molecules, to build a VIP service life prediction model to accurately predict the effectiveness of VIP. Glass fiber/flame wool vacuum insulation board: thermal conductivity ≤1.5mW/(m·K), service life ≥60 years, recommended temperature range: -20℃-120℃, fire resistance level A1. Shape: Can be processed into flat plate/arc/cylinder/opening according to the application. Polyurethane vacuum insulation board: thermal conductivity ≤4.0mW/(m·K), service life ≥20 years, recommended temperature range: -10℃-100℃, shape: flat plate, holes can be opened. Silica/aerogel/phase change material vacuum insulation board: thermal conductivity ≤3.0mW/( m·K), service life ≥120 years, fire resistance rating A1. Recommended temperature range: -20℃-120℃, shape: flat plate/opening. This technology optimizes the VIP structural composition and improves the process to improve the thermal insulation performance by more than 30%. The developed VIP board has a thermal conductivity as low as 1.5mW/(m·K)(Conventional insulation materials are 20-200 mW/(m·K)), and the insulation performance is 10-100 times that of conventional insulation materials; the materials used have no pollution to the environment during the entire life cycle of the VIP; depending on the use occasion, the developed VIP can be non-combustible and has a fire protection rating of Class A; the invented VIP, which can penetrate into the gas, has a service life of more than 120 years.
