HEAT-INSULATED SEALED TANK Russian patent published in 2022 - IPC F17C3/02 

FIELD: heat insulation materials.

SUBSTANCE: group of inventions relates to a sealed and heat-insulated tank included in a supporting structure (2). The tank includes one inclined wall (1) of the tank forming an angle with a horizontal direction and attached to the supporting wall of the supporting structure (2). The tank wall (1) has a multilayer structure, including a heat-insulating barrier (3) sequentially in the direction of the thickness from the outside to the inside of the tank, held on the corresponding bearing wall, and a sealed membrane (4) held by a heat-insulating barrier (3). The tank includes sealing strips (15) in the space formed between the heat-insulating barrier (3) and the load-bearing wall. Sealing strips (15) divide the space between the heat-insulating barrier (3) and the load-bearing wall into many consecutive zones (14) in the direction of the greatest slope of the wall. Zones (14) are extended along the entire transverse dimension of the tank wall (1) in a transverse direction inclined relative to the direction of the greatest slope.

EFFECT: elimination of the thermosiphon effect.
