Definitions
- Reservoir for pressurized fluid, especially for liquefied gas for pressurized fluid, especially for liquefied gas.
- the present invention relates to a reservoir for pressurized fluid, more particularly a fluid under high pressure, that is to say much greater than 1 MPa, typically greater than 5 MPa.
- a particular, but not exclusive, field of application of the invention is that of tanks for liquefied gases, in particular tanks for liquefied propane gas (LPG) used on motor vehicles.
- LPG liquefied propane gas
- the object of the invention is to provide a reservoir for fluid under high pressure which does not have these drawbacks and for this purpose proposes a reservoir comprising a plurality of elementary reservoirs connected in parallel to at least one collecting device, and sealing means allowing isolating any of the elementary reservoirs in response to a pressure drop therein.
- the elementary reservoirs are advantageously formed by tubes.
- a first advantage of the invention resides in a very great ease of adaptation to the available space. Indeed, the resistance to pressure is determined by the section and the wall thickness of each elementary reservoir, whatever the general shape of the reservoir. It is then possible to distribute the volume of the tank in the available space, by using elementary tanks of different lengths, or by arranging them in rows with variable numbers per row, or by grouping them into separate subsets connected together. . This possibility is particularly interesting for motor vehicles to ensure that the tank housing does not penalize the useful volume.
- the tank is simple and inexpensive to produce. This is particularly the case with elementary tanks in the form of tubes since the same tubes, cut to the desired lengths, make it possible to produce reservoirs of all shapes and all volumes.
- these elementary tanks have an ability to contain an external pressure, typically a relative depression of the elementary tank, which any complex form of container prohibited without specific architecture and sizing.
- the present invention also offers the possibility of using various materials for elementary tanks, for example metals, metal alloys or composite materials.
- the latter may be reinforced with carbon fibers, "Kevlar” (registered trademark) or glass and with a resin matrix, for example epoxy.
- Another advantage of the tank according to the invention is its safety.
- the sealing means the damage to an elementary tank does not jeopardize the entire tank and its contents and limits the nuisance on the environment in the event of a leak.
- the low flow rate and the total volume of fluid escaping when only one elementary tank is damaged means that certain restrictions on use, such as for example prohibited access to road tunnels, may no longer be justified.
- the closure means are in the form of a valve, for example formed by a flexible membrane, mounted at each end of the elementary tank connected to a collector, the valve closing the end of the elementary tank in response to a fall. of the pressure prevailing in the elementary reservoir with respect to the pressure prevailing in the manifold.
- the same flexible membrane can be mounted in a collector connected to a plurality of ends of elementary tanks, to be common to several elementary tanks.
- the reservoir may be provided with a protective shield covering at least each spaced surface of the reservoir.
- the shield advantageously has a shielding structure composed of a rigid covering sheet and a thick underlying layer of foam or honeycomb foam material.
- the covering sheet for example made of composite material, is capable of partially absorbing the energy of an impact or of a projectile and of transmitting the unabsorbed energy to the foam material which is capable of diffusing it over a large area. tank surface to avoid deformation of underlying structures. The value of the shocks to be absorbed without functional damage to the tank, as a whole, will condition the size of the shield.
- FIG. 3 is a detail view showing the connection of an elementary tube to a manifold in the tank of Figures 1 and 2;
- FIGS. 4 and 5 are very schematic sectional views showing means for closing elementary tubes in the tank of Figures 1 and 2;
- FIG. 6 is a sectional view of a tank according to the invention provided with a protective shield against impact and projectiles;
- FIG. 7 is a very schematic view showing an embodiment in several parts of a tank according to the invention.
- Figures 1 and 2 show a reservoir 10 consisting of a plurality of elementary tubes 20 connected in parallel to manifolds 30.
- the tubes 20 are arranged parallel to each other and in several superimposed rows, that is to say with a "bundle” arrangement.
- the tubes have the same diameter and wall thickness. They are for example made of metal, such as steel or of a composite material, such as epoxy resin reinforced with carbon fibers or "Kevlar" (registered trademark).
- the lengths of the tubes 20 and the numbers of tubes in the rows are chosen so as to optimally occupy the volume available for housing the tank, for example under the chassis of the vehicle.
- the limits of the available volume are indicated by dashed lines.
- each tube 20 is connected to a collector 30.
- each collector 30 is in the form of a tube to which the elementary tubes 20 of the same row of tubes are connected.
- Additional collectors 32, 34 connect the collectors 30 to each other and in parallel at the two ends of the tank.
- the collectors 32, 34 are connected to a line 36 connecting the reservoir 10 to a use outlet and to a filling inlet (not shown).
- Each end of the elementary tank 20 is connected to a manifold 30 by means of a connector 22 which is screwed or welded at one end 22a, at the end of the elementary tank 20 and which is screwed or welded at its other end, to the collecting tube 30.
- the connector 22 penetrates slightly into the tube 30, at this other end 22b, the latter projecting inside the tube (FIGS. 3, 4, 5).
- each manifold assembly at each end of the tank may be constituted by a coil traversing all the rows of tubes, or by a hollow flange.
- the flange is then formed of two spaced parallel walls connected to one another in a sealed manner around their periphery, and one of the walls being provided with holes through which the fittings for the elementary tubes penetrate.
- FIGS. 4 and 5 show a flexible membrane 40 which constitutes a means for closing off an elementary tube 20 in the event that the pressure therein would fall for example following a rupture or deterioration resulting from an impact or a projectile impact.
- the membrane 40 is in the form of a strip of flexible material which extends over the entire length of the collector 30 with its faces perpendicular to the axes of the elementary tubes 20 of the row associated with the collector. In this way, the membrane 40 constitutes a sealing means shared by all the tubes 20 in this row. At its ends, the membrane 40 is fixed to the closed ends of the collector 30, for example by gluing or by mechanical means.
- the flexible membrane 40 is for example of composite material composed of an elastomer reinforced by fibers. In normal operation, the membrane 40 is not deformed and leaves free access to the tubes 20 connected to the collecting tube 30 (FIG. 4). Maintaining an identical pressure on each face of the membrane results from the fact that the latter does not divide the collector 30 into two longitudinal volumes insulated from one another in a sealed manner.
- a flexible membrane is advantageous because of its low cost and its reliability, since no moving part is required.
- other embodiments of the closure means may be used, for example non-return valves associated with each end of the elementary tube, the non-return valves then being able to be subjected to a slight restoring force which keeps them open in the absence of vacuum in the corresponding elementary tubes.
- the use of elementary tubes which can be of a fairly small diameter, typically less than 5 cm, or even 1 cm, makes it possible to withstand very high pressures with relatively thin walls.
- tubes of carbon / epoxy composite material with an outside diameter of 8 mm and a wall thickness of 1 mm can withstand an internal pressure of 100 MPa.
- a tank even for a high pressure fluid can therefore be significantly lighter than a single-body tank of the same capacity.
- the tank In order to protect the elementary tubes against shocks and projectiles, it is desirable to provide the tank with a protective shield at least on each exposed face.
- Such a shield is shown only in FIG. 6.
- it comprises a layer of foam material 42, in particular of polyurethane foam, which envelops the bundle of elementary tubes 20 and the collector tubes.
- the layer 42 is coated by a rigid structure or shell 44, for example in a composite with an epoxy resin matrix reinforced with aramid fibers.
- the shell 44 can be formed by draping the foam 42 with impregnated fibrous textures and polymerizing the resin. Alternatively, the impregnated fibrous textures can be draped over the internal face of a mold inside which the reservoir is introduced to form the foam coating layer.
- This shield can also be made of an envelope of fibers, for example aramid, and of a thickness of material in “honeycomb” structure in place and according to the foam material.
- a protective shield is more particularly desirable when the elementary tubes (and the collecting tubes) are made of a non-metallic material, in particular of a composite material which, often, is less resistant to shocks and shows less plasticity than metallic materials.
- the rigid shell 44 distributes the pressure on the surface of the foam 42.
- the latter amplifies the distribution of pressure, so that no deformation is induced on the rear face of the foam, in contact with the elementary tubes of the tank.
- a reservoir 10 which may have a complex shape but produced in a single set of elementary tubes 20.
- each sub-assembly comprises a plurality of elementary tubes, the lengths and arrangements of which are chosen according to the space available.
- the sub-assemblies 12, 14 are connected to one another by one or more pipes 38.
