·Conduction and heat transfer: nano-sized fine powder, very small nano-sized point contact thermal resistance is very large, making the effect of conduction and heat transfer very small
· Convective heat transfer: the average free path of the nano-scale pores is 20 nm, and the average free path of the static air at constant temperature is 60 nm. The air molecules are locked and cannot conduct micro-convection heat transfer, which makes the convective heat transfer effect very low
· Radiative heat transfer: The thermal insulation material is added with nanometer high temperature anti-infrared material, which reduces the radiation heat transfer dominated by radiation at high temperature to an ultra-low point.
