Definitions

  • the invention relates to a container for cryogenic liquids, consisting of an outer container and a number of inner containers, wherein there is preferably in the space between the inner containers and the outer container for thermal insulation, a vacuum.
  • a container for cryogenic liquids consisting of an outer container and a number of inner containers, wherein there is preferably in the space between the inner containers and the outer container for thermal insulation, a vacuum.
  • Such containers are made, for example EP 0 981 009 A2 known, which is considered as the closest prior art according to the introductory part of claim 1, and intended for installation in motor vehicles, aircraft or spacecraft. They contain liquefied gases which are removed from the container for use either as fuel or for other purposes (such as cooling medium).
  • the vacuum insulation is intended to withhold the entry of heat and thus evaporation of the cryogenic liquids and the associated increase in pressure.
  • the cryogenic liquid can also be stored at high pressure.
  • the stored amount is increased at the same volume, but on the other hand, the container is heavier to withstand the pressure load.
  • the vacuum insulation has a pressure on the containers.
  • the outer container is from the outside by the atmospheric pressure loaded, because in its interior the vacuum acts.
  • the inner containers are loaded by the full internal pressure, because they are surrounded by a vacuum.
  • the cylindrical container shape is very unfavorable for use in vehicles for reasons of space. Therefore, the development goes to box-shaped flat containers. In a flat construction, however, both inner and outer containers are exposed to high loads due to the large flat and free surfaces, which can only be absorbed by massive supports. This results in increased weight (particularly negative in road and air vehicles) and increased heat conduction into the interior of the container.
  • longitudinal axis direction is understood to mean a direction substantially parallel to the direction of the longitudinal axes of the adjacent inner containers. Small deviations from parallelism fall within the scope of protection of this claim.
  • the container is a tank in flat construction, although certain deviations in the sense of a slight curvature of the ceiling, floor and / or side surface of the outer container are allowed and fall within the scope of the subject protection claim.
  • a plurality of inner containers are arranged in the outer container, wherein the longitudinal axes are arranged substantially parallel and in a plane. Slight deviations with respect to the parallelism of the longitudinal axes or a slight axial offset of an inner container from a common level, however, are allowed and covered by the scope of protection of the present protection claim.
  • the outer container can be stabilized against occurring compressive and tensile loads from the inside as well as from the outside.
  • Such compressive and tensile loads can be caused for example by an evacuation of the outer tank or by mechanical external loads on the outer tank.
  • a construction of a flat container which does not have the disadvantages known and discussed in the prior art. It should be as light and easy as possible with the best thermal insulation.
  • this is achieved in that the inner containers are juxtaposed cylinders with a bottom on both sides, and that the planar wall parts of the outer container are supported against one another by supports arranged between the cylinders. Thanks to the arrangement of several inner container side by side (not all inner container necessarily in a plane next to each other must be arranged) can be maintained at internal pressure particularly favorable cylindrical shape. This makes it possible to store the cryogenic liquid under high pressure even with relatively small wall thickness.
  • the cylinders can be used in the manner of a modular system for containers of different external dimensions in different numbers and in different constellations.
  • the support is a pressure support, that is to say a support for the support of / against compressive forces and / or a tensile support for the support of / against tensile forces.
  • the inner containers are provided as separate containers, for example as structurally separate cylindrical tank containers, which are filled and / or emptied via a suitable device, optionally together or separately.
  • the support based on a section of the support with the plane of the longitudinal axes of the adjacent inner container, a measured along the longitudinal axis direction maximum longitudinal extent and normal to a measured between the adjacent inner tanks maximum width extent.
  • the ratio of maximum length extension to maximum width extension is at least 1.25: 1. This results in a particularly good stability of the container according to the invention.
  • the support between two inner containers consists of a plurality of support elements arranged along the longitudinal axis
  • the maximum length expansions or maximum width expansions of the support elements are added to determine the effective total length extension or total width extension of the support acting between the inner containers. Overlays of two or more pressure support elements in the longitudinal or width direction contribute only once to determine the effective total length or the effective total width of the support. The thus determined effective Total length or total width of the support elements is considered as dimension (length extension, width extension) of the support.
  • the support elements are arranged symmetrically or at approximately equal distances from one another viewed in the direction of the longitudinal axis of the inner container. This ensures that the force input through the outer container occurs evenly, without distortion of the container construction.
  • the ratio of maximum length extension to maximum width extension is at least 2: 1.
  • the ratio of maximum length extension to maximum width extension is at least 5: 1.
  • the top wall opposite the bottom wall is supported longitudinally between the at least two inner containers, in the longitudinal axis direction, over at least 10% of the length of the outer container by the support.
  • the top wall opposite the bottom wall is supported longitudinally between the at least two inner containers, in the longitudinal axis direction, over at least 25% of the length of the outer container by the support.
  • the push-rest has a minimum length of at least 10%, in particular of at least 25%, of the longitudinal dimension of the outer container.
  • the push-rest has a minimum length of at least 10%, in particular of at least 25%, of the longitudinal dimension of the inner container.
  • the longitudinally arranged between the at least two inner containers support several separate support elements.
  • the support extends over the entire length of the at least two inner container.
  • the at least two inner containers are cylindrical.
  • the at least two inner containers are suspended at their ends on the side walls of the outer container, so that thermal expansions are taken in the longitudinal direction.
  • the inner containers are made of stainless steel.
  • the inner containers are surrounded by carbon fibers embedded in a plastic matrix.
  • the inner containers are suspended at their mutual bottoms on end walls of the outer container, so that thermal expansions are taken in the longitudinal direction.
  • the inner container are fixedly connected at one end to an end wall of the outer container and freely movable at the other end in the longitudinal direction.
  • the outer container is made of thin sheet metal and is wrapped with fiber embedded in a plastic matrix.
  • the support may also be designed such that it at least partially supports the inner container transversely (ie transversely to the longitudinal axis direction), either in the direction of the width of the outer container and / or in the direction of the height of the outer container or at least partially holds the inner container in position in these directions.
  • the outer container is summarily with 1 and the inner containers arranged parallel to each other therein are denoted by 2, 3, and 4.
  • the inner containers are cylindrical tubes, preferably made of stainless steel.
  • the surrounding outer container 1 with distance can thus obtain a flat design. It is essentially a flat cuboid whose side surfaces can be rounded. In any case, he has two flat wall parts 10,11.
  • a vacuum that forms a so-called "super-insulation" together with other measures.
  • the flat wall parts 10, 11 are compressed by the atmospheric pressure.
  • the inner containers 2, 3, 4 are already pressed to the outside at atmospheric pressure prevailing in them.
  • Fig.2 are the supports 12, 13 individual supports.
  • the inner container 2, 3, 4 can be suspended in a known manner by means of mutually known suspensions 17, 18 on the end walls 14, 15.
  • FIGS. 5 and 6 differs therefrom in that the supports 22, 23 extend over the length of the inner container 2, 3, 4 and that the inner container 2, 3, 4 only on the one hand by means of heat-insulating feet 32 attached to an end wall 33 of the outer container 1 and with its other End are freely movable.
  • the supports 23, 24 I-shaped profiles, the foot parts 24, 25 bear against the inner walls of the flat walls 10, 11 and the web portions have reinforcing ribs 26 in order to increase their buckling strength.
  • the outer container 1 may be made of a very thin sheet metal, if it is also provided with a fiber-reinforced wrapping 31.
  • FIGS. 7 and 8 another possible embodiment of a container according to the invention for a cryogenic liquid is shown.
  • the Container has an outer container 40 with a length L, a width B and a height H.
  • FIGS. 7 and 8 differs from other embodiments in that the support 34 has two separate elongated support members 35 and 36, which are arranged along the longitudinal axes 37 of the inner container 38, ie in the longitudinal axis direction.
  • Fig. 7 is a section of the support along the plane through the two longitudinal axes 37 of the inner container 38 can be seen.
  • the longitudinal extent (along the longitudinal axis of the cylindrical inner container) of the support in cross-section is a multiple of the width dimension thereof.
  • the maximum length dimensions or maximum width dimensions of the cross section of the individual support elements, each arranged between two inner containers are added. Shares of the cross section overlapping in the direction of the longitudinal axis or in the direction of the width (section with plane through the two longitudinal axes 37) of the support elements are taken into account only once in this addition.
  • FIGS. 7 and 8 shows that in the illustrated embodiment, the cumulative extent of the cross-sectional area of the support 34 in the direction of the longitudinal axis is substantially greater than in the direction between the inner containers and at right angles to the longitudinal axis in the direction of the width of the outer container 40.
  • the outer container 40 is in FIGS. 7 and 8 each shown only schematically.
