System comprising a cryogenic container and a thermal siphon

A system comprising a vehicle and a cryogenic container carried along on the vehicle and comprising an inner tank and an outer container which is vacuum-insulated relative to said inner tank, the system furthermore comprising a fluid conveying device and a pipeline that is routed out of the inner tank for the removal of cryogenic fluid and is connected to the fluid conveying device,

• wherein the fluid conveying device is arranged outside of the inner tank, the pipeline comprises a thermal siphon with at least one section rising towards the fluid conveying device, which is at least partially arranged in an area that is insulated with respect to the cryogenic fluid located in the inner tank, and
• wherein a vent line that can be closed by a valve in said area, on a removal level of the fluid conveying device, is connected to the pipeline or directly to the fluid conveying device and is routed back into the inner tank above the connection point to the pipeline or above the connection point to the fluid conveying device,
• wherein the section rising towards the fluid conveying device is at least partially arranged inside the cladding pipe,
• wherein the vent line is connected to the pipeline within the cladding pipe, is routed out of the cladding pipe inside the inner tank and is routed out of the inner tank with a separate cladding vent pipe.
