Definitions

  • the technical field of the present invention is that of liquefied gas tanks, such as liquefied natural gas (G.N.L), intended to equip motor vehicles.
  • liquefied gas tanks such as liquefied natural gas (G.N.L)
  • G.N.L liquefied natural gas
  • Liquefied natural gas is natural gas converted into liquid form. This liquid state is reached when the gas is cooled to a temperature of about -161 ° C at atmospheric pressure.
  • Liquefaction reduces the gaseous volume of natural gas and stores it in one or more tanks installed, for example, on the chassis of the truck.
  • the liquefied natural gas contained in the tank is regasified so as to feed the truck engine.
  • This fuel is less polluting than gasoline and diesel, and the autonomy of trucks using this fuel makes them suitable for long-distance road transport.
  • Liquefied natural gas tanks of trucks are designed to meet strict safety requirements, including pressure and maintaining a very low temperature, to maintain the gas in its liquid phase.
  • the tanks usually used have a cylindrical shape and have a double wall stainless steel between which are arranged an insulator multi-layer and vacuum classically. Their weight is therefore relatively important and their useful volume is reduced.
  • the tanks having this shape occupy a large space and are not adapted to the spaces / compartments of various shapes of the vehicle in which they are intended to be implanted.
  • the invention proposes for this purpose a tank for a motor vehicle intended to contain liquefied gas, such as liquefied natural gas.
  • the invention provides a tank of liquefied gas (LNG for example) double wall generally of substantially parallelepipedal shape comprising a container forming an inner wall and an outer envelope disposed around said container outer protective wall.
  • LNG liquefied gas
  • an intermediate space containing vacuum and / or an insulating material.
  • the fastening of the container to said outer envelope by suspension means allows to provide a degree of freedom between the two elements, so as to limit heat transfer by conduction and to compensate the thermal expansion / retraction due to the cooling of the internal container by limiting the stress inputs.
  • suspension means also allow mechanical movement of the container relative to said outer envelope.
  • the parallelepipedal shape of the container optimizes its storage capacity in liquefied gas and the parallelepipedal shape of the outer casing allows optimal integration of the reservoir to the vehicle architecture.
  • these suspension means allow a relative displacement of said container with respect to said outer envelope less than 10 mm, for example between 1 and 6 mm, and more specifically between 1 and 4 mm.
  • the thermal contraction of said container may be equal to 4 mm on each side of the container for example.
  • the suspension means thus make it possible to compensate for this retraction of the internal container.
  • the liquefied gas can be LNG (liquid methane), or liquid nitrogen for refrigerated trucks, for example.
  • said container is connected to a first lateral end of said outer envelope by suspension straps and to a second lateral end of said outer envelope by a suspension ring.
  • said suspension ring is attached to the inner surface of a side wall of said outer envelope and is fitted on a stud carried by the outer surface of a side wall of the container.
  • said suspension straps and said suspension ring are made of a thermally insulating material.
  • suspension means may alternatively be springs or silentblocs when these suspension means are insulating.
  • said container is connected to a first lateral end of said outer envelope by suspension straps and to a second lateral end of said outer envelope by suspension straps.
  • suspension straps are made of a thermally insulating material.
  • said internal reinforcing structure comprises a reinforcing framework secured to the inner wall of said container, the internal reinforcing structure comprising a plurality of reinforcing rings, substantially octagonal, spaced along the longitudinal axis of the container, and extending transversely to said longitudinal axis.
  • This reinforcing framework optimizes the mechanical strength of the container at the internal pressure of the liquefied gas and avoids the phenomena of inertia of the contained fluid.
  • a coiled cable could be used.
  • said reinforcing rings are mounted spaced apart on reinforcing bars extending parallel to the longitudinal axis and arranged around the periphery of the reinforcing rings, said reinforcing bars being each secured to a reinforcing rail fixed on the wall. internal of said container.
  • said internal reinforcing structure comprises a plurality of angle reinforcing plates fixed on the inner wall of said container and each connecting two adjacent inner faces of said container.
  • the container is made of aluminum.
  • said outer envelope is made of a fire-resistant material.
  • said outer envelope is covered on its surface exterior or interior of a fire resistant coating.
  • the outer shell can be made of aluminum or composite materials.
  • a fire resistant coating may be arranged alternatively or in addition to the outer surface of the container.
  • the internal reinforcing structure may be made of aluminum, or a composite material, for example.
  • the wall of the container and the wall of the outer casing are distant from each other, the space between these walls being filled with insulating means.
  • the space between the wall of the container and the wall of the outer casing is, for example, between 25 and 50 mm.
  • the internal reinforcing structure comprises a plurality of reinforcement plates spaced along the longitudinal axis of said container and extending transversely to said longitudinal axis.
  • said reinforcing plates are solid and have at least one orifice for passing the liquefied gas within said container.
  • the container comprises a reinforcing rod extending parallel to said longitudinal axis and connecting the side walls of the container through said reinforcing plates.
  • This reinforcing rod allows the maintenance of the bottoms, or side walls, of the container.
  • the internal reinforcing structure further comprises a reinforcement frame having a generally parallelepipedal shape and disposed against the inner wall of said container.
