TANK-THERMOS Russian patent published in 2002 - IPC

FIELD: transport engineering. SUBSTANCE: invention relates to devices for transportation of liquid products with temperature differing from ambient temperature, viscous products, for instance fuel oil difficult to drain owing to rise of viscosity caused by reduction of temperature, as compared with filling temperature, cooled liquid food products and liquefied gases. Proposed tank-thermos has reservoir 1 made of cold-rolled sheet of stainless steel with polished surface, additional three-layer load-bearing envelope 2 made of glass honeycomb plastic, end face frames 3, connecting frames made of non-metallic material, and multiple layer heat insulation. Heater 5 are arranged in lower part. Filler neck 9 of reservoir 1 is covered by heat shielding hood 10. Multiple layer heat insulation is formed by two layers of heat insulating plates 6, flexible heat insulating material and reflecting coatings. EFFECT: reduced heat losses, improved manufacturability, reliability and ecological safety in service. 4 dwg
