Definitions

  • the invention relates to a container for cryogenic fuels in flattened construction, which is surrounded by insulation.
  • a flattened construction is particularly desirable for cryogenic fuel containers when they are intended for use in motor vehicles.
  • the hitherto usual ton- formigen container with the surrounding super-insulation are conceivable unfavorable because of their poor space utilization, they take up the entire trunk of a motor vehicle to complete.
  • Such a container is known from EP 1 067 300 A1. It consists of an upper and a lower shell made of plastic, which are connected in many places by tubular tensile struts with each other to prevent buckling of the shells by the internal pressure.
  • a favorable shape be given, but this must be redeveloped and designed for each model, then each time new shapes and tools are to be purchased.
  • a particular problem with non-cylindrical containers is the thermal stresses which occur, for example, during filling of the container (temperature differences occur in liquid hydrogen up to 333 degrees Celsius).
  • the container is composed of a plurality of identical straight profiles which can be connected to one another and are arranged parallel to one another and whose at least one outer boundary wall is arranged at a small distance parallel to a boundary wall of an adjacent profile and at their open ends a common cap on both sides followed. Due to the similarity of the elements not only different shapes are feasible, but it is also the interpretation easier, because the stresses and deformations of the individual elements are the same. The fact that the outer walls of the profiles are parallel, a densest packing is achieved. The caps make the connection between the contents of each juxtaposed profiles ago.
  • the small distance between the parallel outer walls of the profiles allows the process-safe cleaning of the outer surfaces of the inner tank and production of the necessary for heat insulation high vacuum between the inner tank container and the surrounding outer container. Since the profiles communicate with one another via the caps at their ends, their connection and sealing is also so simple that containers according to the invention can be produced automatically.
  • the pipe connections for the supply and discharge to the outside are also integrated in the caps, so that the elements only consist of unit sections which are cut to length in the correct length and which do not require complicated require machining. Also, the manufacturing costs can be significantly reduced.
  • the outer boundary walls of the profiles form in cross-section substantially a rectangle, in particular an equilateral rectangle - a square (claim 2). So they can be arranged side by side and one above the other with the greatest packing density and are also process reliable in the extrusion process produced. Furthermore, this results in an optimum thermal behavior and a flat support for the reflection films, which are provided for forming a super insulation in the vacuum space between the container and its outer container.
  • the outer profiles must have large curves, otherwise the caps can not be produced.
  • the small distance between the parallel outer walls of the profiles for reliable production of the vacuum is 1 to 8, preferably 3 to 5 millimeters. This counteracts the attraction due to capillary forces during the cleaning process.
  • the profiles have inside over their entire length reinforcements with longitudinal generatrix (claim 4). These inner profilings thus connect over the entire length of the outer walls of the profiles and counteract the internal pressure.
  • the reinforcements in rectangular or square cross-section of the profile in cross-section symmetrical sides form (claim 5), in the manner of a window cross.
  • the reinforcements are curved like a cross-section in the cross-section and strike the inner side of the outer walls at an acute or obtuse angle (claim 6).
  • an acute or obtuse angle claim 6
  • the reinforcements can have different shapes in cross section. They may be oval, in particular circular arc (claim 7) may be formed so that the thermal stresses are absorbed by the circular arc-shaped profile parts. In a further variant, the reinforcements which are oval or circular in cross section may affect the outer walls (claim 8).
  • the profiles are straight and of constant cross-section over their entire length, they are advantageously either extruded profiles of a suitable light metal alloy, preferably of an aluminum alloy (claim 10) or rolled austenitic steel profiles (claim 11).

Abstract

L'invention concerne un récipient pour combustibles cryogènes, de structure aplati, qui est entouré d'une superisolation. L'invention vise à ce que ledit récipient puisse être adapté à différents modèles de véhicule et à différentes situations de montage, de manière automatisable et économique et qu'il puisse résister à des sollicitations aussi bien mécaniques que thermiques. A cet effet, il se compose de plusieurs profilés (4, 5) similaires, droits et fermés, disposés en configuration différente les uns par rapport aux autres. Ces profilés sont des profilés creux droits, disposés de manière parallèle les uns par rapport aux autres, dont au moins une paroi de délimitation extérieure (14, 15, 16,1 7) conserve un écart de fonction par rapport à une paroi de délimitation extérieure (18) d'un profilé adjacent et à l'extrémité ouverte (28, 29) desquels se raccorde, dans chaque cas, des deux côtés, un capuchon commun, comme espace de raccordement commun des profilés (6, 7). Dans le cas de profilés rectangulaires, les renforcements (24, 25) sont de préférence des lignes symétriques latérales de leurs parois extérieures (14, 15, 16, 17).
