A transport container for helium, with an inner container for receiving the helium, a coolant container for receiving a cryogenic liquid (N2), an outer container, in which the inner container and the coolant container are contained, a thermal shield, in which the inner container is contained and which can be actively cooled with the aid of a liquid phase of the cryogenic liquid (LN2), the thermal shield having at least one first cooling line, in which the liquid phase of the cryogenic liquid can be received for actively cooling the thermal shield, and an insulating element, which is arranged between the outer container and the thermal shield and which can be actively cooled with the aid of a gaseous phase of the cryogenic liquid (GN2), the insulating element having at least one second cooling line, in which the gaseous phase of the cryogenic liquid can be received.
摘要:
A cryogenic pressure container for a motor vehicle has an inner container and an outer container. An evacuated space is arranged between the inner container and the outer container at least in some regions. The inner container has a synthetic material layer. A barrier layer is arranged at least in some regions between the synthetic material layer and the evacuated space. The barrier layer is designed and arranged so as to at least reduce the transfer of constituents leaking out of the synthetic material layer into the evacuated space, wherein a gap is formed at least in some regions between the barrier layer and the synthetic material layer.

A suspension system (3) for an inner container (2, 2′) mounted for thermal insulation in an outer container (1, 1′) comprises a single fixed bearing (30, 31, 32, 33, 34, 35, 36, 37, 38, 39) comprising fixed bearing securing elements (5, 5′, 5″, 5′″) which engage, on the one hand, the outer container and, on the other hand, the inner container and which can be stressed in tension and in compression, the fixed bearing securing elements (5, 5′, 5″, 5′″) engaging while being arranged so as to be distributed in an annular installation space (7) defined between the inner container (2, 2′) and the outer container (1, 1′) and the fixed bearing securing elements (5, 5′, 5″, 5′″) engaging the outer container (1, 1′) while being distributed in the annular installation space (7). In addition, a floating bearing (41, 42, 43, 44, 45) arranged in the outer container (1, 1′) and supporting the inner container (2, 2′) and designed with a floating bearing ring (10, 10′) can be provided, with annularly distributed floating bearing securing elements (11, 11′), which can be stressed in tension and in compression, engaging, on the one hand, the floating bearing ring (10, 10′) and, on the other hand, the inner container or the outer container. The floating bearing ring (10, 10′) can be spring-biased by means of tension springs (12) or compression springs (13).
摘要:
A double walled vacuum insulated cryogenic vessel including a support system for the inner vessel that comprises an inner vessel support, a support bushing, and an outer vessel support. The inner vessel support is affixed to the inner vessel and the outer vessel support is affixed to the outer vessel. Between the two supports is a support bushing which is not affixed to the inner vessel support, the outer vessel support, the inner vessel, nor the outer vessel. Anti-rotational support is provided either by mechanical means, shapes, or secondary support structures.
摘要:
A cryogenic propellant depot and sunshield are provided for operation in earth orbit to fuel or refuel other space vehicles. The sunshield is deployed to effectively mitigate solar radiation emanating from the earth and the sun thereby providing a long term storage solution for cryogenic fluids prone to boil-off. The depot has supporting subsystems to include station keeping equipment and communication equipment so that the depot can be independently controlled. Inflatable booms are used to deploy the sunshield in a desired pattern around the depot.
摘要:
The present invention provides a thermal radiation shield (1) for a cryostat, formed of a plastic-metal hybrid material, which comprises a plastic component (23) and a conductive filler material (21) comprising a metal. The thermal radiation shield may be formed by injection moulding.
摘要:
A cryogenic storage tank having an insulated inner vessel disposed within an outer vessel. A common-access tube or conduit is used to route the various fluid flow lines into the interior of the inner vessel. The use of a common-access tube reduces the number of obstructions that the insulation must accommodate and facilitates the production of the storage tank.
摘要:
Method for protecting a cryogenic tank, the tank comprising two concentric casings between them delimiting an inter-wall space in which a so-called low pressure obtains, the method involving: a step of detecting an impact on the tank and/or an increase in pressure within the inter-wall space, characterized in that it involves a step of generating a stream of inert gas within the inter-wall space only if an impact on the tank of a determined intensity and/or a determined increase in pressure at the inter-wall space is/are detected.
