Definitions

  • the present invention relates to a cryogenic tank for storing a cryogenic medium, in particular for storing hydrogen.
  • cryogenic media i.e. cryogenic and at least partially liquid media, such as hydrogen or helium
  • cryogenic and at least partially liquid media such as hydrogen or helium
  • gases in particular hydrogen
  • the storage of gases, in particular hydrogen, in the cryogenic state is particularly suitable for mobile use in terms of energy density, especially in motor vehicles to achieve long ranges.
  • cryogenic tanks For use in motor vehicles, the requirements for cryogenic tanks in terms of thermal insulation, weight and safety are particularly high.
  • vacuum-insulated storage containers are usually used for thermal insulation, which consist of a double-walled container with an inner container and an outer container. The cavity between the two containers is evacuated to reduce the heat flow and is provided with an insulation layer.
  • Boil-Off Management (BOM) system is responsible for the oxidation of the hydrogen.
  • BOM Boil-Off Management
  • the corresponding inflow to the BOM system is referred to as boil-off gas (BOG).
  • a valve arranged between the BOM system and the inner container acts as a boil-off valve.
  • the present invention sets itself the task of developing a cryogenic tank in such a way that heating of the boil-off gas from cryogenic temperatures to ambient temperature can be achieved easily and cost-effectively.
  • the present invention solves this problem by means of a cryogenic tank with the features specified in claim 1.
  • the heating of the boil-off gas along this thermally contacted section can be achieved passively via the physical effect of heat conduction via metallic components such as lines and outer container. Due to the large surface area between the outer container and the surrounding air, the outer container is kept at ambient temperature.
  • the thermal setting/conditioning or heating of the BOG can be easily achieved by designing and adjusting the distance of the thermally contacted section.
  • the outer container includes a container wall with an outside and an inside.
  • the pipeline lies directly on the outside of the outer container or indirectly on components connected to the outside in a heat-conducting manner.
  • the pipeline lies directly on the inside of the outer container or indirectly on components connected to the inside in a heat-conducting manner.
  • the section of the pipeline which is connected in a heat-conducting manner to the outside or alternatively to the inside or to a component arranged on the outside or inside of the outer container, can be in a meandering or spiral shape on or on the outer container in the longitudinal direction of the lateral surface of the outer container be arranged directly or indirectly.
  • the thermal coupling of the pipeline can advantageously be produced at least in sections using both mechanical connection types, such as screw or clip connections, as well as material connection types, e.g. welding or hard/soft soldering.
  • a cryotank 1 for storing a cryogenic medium, in particular for storing hydrogen is shown.
  • the following description refers to the use of hydrogen as a cryogenic medium.
  • other media can also be used.
  • the cryotank 1 is a double-walled container and includes an inner pressure-tight storage container 2, which is stored in an outer container 4.
  • the storage serves to position the two shells of the double-walled container and includes suspensions, not shown, in sections between the outer container 4 and the inner container/storage container 2.
  • the cavity between the inner storage container 2 and the outer container 4 is evacuated and provided with an insulation layer to reduce the heat flow and thus to protect the storage container 2 from additional heat.
  • the cavity is referred to below as vacuum space 5.
  • the outer container 4 comprises a container wall delimiting the outer container with an outside 4a facing the outside environment/air and an inside 4b facing the storage container 2.
  • the cryogenic medium in particular hydrogen, is located in the lower region of the storage container 2, namely below the liquid surface 6 shown as a wavy line in the figures as a liquid in the storage container 2, above the liquid surface 6 in a gaseous state.
  • a gas sampling line 8 is set up to remove the gaseous medium from the storage container 2, so that the free end of the gas sampling line 8 ends in the storage container 2 above the liquid surface 6, near the ceiling of the storage container 2.
  • the free end of the gas sampling line 8 can also lie below the liquid surface 6.
  • the gas sampling line 8 forms a sampling line which, starting from the storage container, supplies the gaseous medium, possibly with the interposition of a heat exchanger, a pump and/or other fittings, to a consumer via a consumer connection 10, in particular to a fuel cell as a consumer.
  • the gas extraction line is led from the interior of the storage container 2 through the container wall of the storage container 2, the vacuum space 5, the container wall 4a of the outer container 4 into the external environment A.
  • the storage container 2 also includes, as is well known, a safety device 3 with a line and a pressure relief valve. Further details about the gas sampling line 8 and components connected to the flow in the gas sampling line 8, such as mass flow valves, etc., are not shown.
  • cryotank 1 for discharging boil-off gas comprises a pipe 7, the free end of which also ends above or below the liquid surface 6 and is led out of the double-walled cryotank 1 and includes a BOG valve 9.
  • the outer container 4 has a container wall with an outside 4a. The outside 4a of the cryotank 1 is assigned to the ambient air temperature.
  • the BOG that occurs at least temporarily in the storage container 2 is discharged into the environment through the pipe 7 and then via the BOG valve 9.
  • the pipeline 7 is guided from the storage container 2 through the vacuum space 5 and the container wall of the outer container 4 to the outside 4a.
  • the pipeline 7 lies on the outside 4a directly in the longitudinal direction x1 on the lateral surface of the outer container 4.
  • the line 7 can also lie on the inside 4b of the container wall of the outer container.
  • the BOG can thus be heated to ambient temperature until the BOG valve 9 is reached.
  • the thermal coupling of the pipeline to the outside 4a or to components/assembly arranged on or on the outside 4a can take place over the distance x1 using different connection techniques.
  • Both screw and clip connections can be used, as can material-locking types of connection such as soldering or welding.
  • the section of the pipeline 7 which is in a heat-conducting connection on the outside 4a or the section of the pipeline 7 which is thermally coupled to the outside 4a and rests directly or indirectly on the outer container 4 can also be any other be designed.
  • the pipeline 7 can run in a meandering or spiral shape on or around the outer container 4.
  • ceiling and “floor” refer to the usual installation position of the storage container, for example in a moving, floating or flying transport device, with gravity acting towards the bottom of the storage container during normal operation of the transport device.
