Loading, storage and delivery apparatus and method for fluid at cryogenic temperature.

摘要

An fluid storage and delivery apparatus and method, fluid loading apparatus and method, and a fluid supply carriage and conditioning unit are disclosed, the storage apparatus including a compact and lightweight dewar having a pressure vessel and outer shell for containing cryogenic temperature mixed gas at supercritical pressure. A passive heat exchanger receiving the mixed gas expelled from the pressure vessel for conducting the gas to a use destination is routed for mass flow transfer of heat from the surface of the outer shell, which preferably is fitted with means to increase the surface area thereof such as fins, to the pressure vessel, heat transfer accomplished thereby being sufficient to maintain the gas in a single phase in the dewar and provide the necessary energy to expel the gas therefrom.
