Abstract
The invention relates to a liquefied-fluid storage tank including a storage wall the inner surface of which defines a storage volume for liquefied fluid, the tank including an exchanger for cooling the fluid contained in the tank in particular to condense vapors of said fluid. The invention is characterized in that the cooling exchanger includes a body of metal, in particular aluminum, in which at least one pipe of a coolant circuit is integrated in order to cool said body and in that the body is in contact with and attached to the outer surface of the storage wall.
Claims12
A liquefied fluid storage tank comprising a storage wall, an outer wall arranged in a manner spaced around the storage wall, and a cooling exchanger for condensing vapors of the fluid contained in the tank, the inner surface of the storage wall defining a storage volume for the liquefied fluid, the space between said walls being under vacuum at a pressure below atmospheric pressure and comprising a thermal insulation layer, wherein the cooling exchanger comprises a mass of metal into which there is integrated at least one pipe of a heat transfer fluid circuit for cooling said mass of metal, the mass of metal is in contact with and attached to the outer surface of the storage wall, and the mass of metal is linked to the outer wall and to the at least one pipe by casting metal in liquid form at melting temperature onto the storage wall and around the at least one pipe so that the at least one pipe is/are embedded in the mass and the mass of metal is overmolded onto the outer wall and the pipes.
