The system also includes a cryogen storage system configured to supply cryogen to the device.

The housing comprises therein a cryogen inlet tube.

A system is provided for vaporizing a cryogenic liquid.

A sparger is positioned at least partially within the vessel and configured to deliver water into the vessel, wherein heat exchanged between the water and the cryogenic liquid vaporizes the cryogenic liquid.

A cryogenic liquid delivery system includes a storage tank (12) holding a quantity of a cryogenic liquid such as liquid oyygen (13) and a vapor space (11).

As cooling medium cryogenic liquid, in particular liquid nitrogen or liquid carbon dioxide, or cryogenic solid such as carbon dioxide snow may be used.

For example, the air can flow through pipes surrounded by cryogenic liquid, or air can flow past pipes filled with cryogenic liquid.

Also disclosed is a system for vaporization of a cryogenic liquid.

The heat load onto the cryogenic vessel is thereby reduced, which in turn reduces the boil-off of cryogen from the cryogenic vessel.

Passage of the second cryogenic liquid through the heat exchange member (22) is able to maintain the first cryogenic liquid in subcooled state.

A piping system moves cryogenic liquid to the heat exchanger where it is vaporized, and then moves vaporized liquid to the vapor space of the cryogenic tank and an application.

The invention relates to a method and a device for evaporating a cryogenic liquid.

The temperature of the cryogenic liqud (24) is lowered by the contact of the gas.

The invention concerns a method of reheating a cryogenic liquid contained in a cryogenic tank (1) with a gaseous ceiling (18).

The system includes a cryogen cooling system configured to be coupled to the superconducting device and to supply cryogen to the device.
