ABSTRACT:
Heat insulation for structures such as cryogenic tanks for example liquid natural gas tanks, often referred to as LNG tanks, is effective at cryogenic and higher temperatures up to the heat and structural limits of the honeycomb materials used which include integral heat radiation shields. The heat transfer is minimized with respect to conduction, by utilizing the minimum heat path possible within the honeycomb also essentially designed to take compressive loads, with respect to radiation, by placing multiple low emissivity heat shields spaced throughout the hexagonal cells, and in respect to convection, by replacing air with a low conductivity gas, or alternately creating a vacuum, to practically eliminate this convection mode of heat transfer.
