A Dewar system is configured to liquefy a flow of fluid, and to store the liquefied fluid. The Dewar system is disposed within a single, portable housing. Disposing the components of the Dewar system within the single housing enables liquefied fluid to be transferred between a heat exchange assembly configured to liquefy fluid and a storage assembly configured to store liquefied fluid in an enhanced manner. In one embodiment, the flow of fluid liquefied and stored by the Dewar system is oxygen (e.g., purified oxygen), nitrogen, and/or some other fluid. |

1. A system configured to liquefy a fluid, and to store the liquefied fluid, the system comprising:
a housing configured to substantially seal the interior of the housing from atmosphere comprising a first piece and a second piece, wherein the first piece and the second piece are configured to be selectably coupled together to substantially seal the interior of the housing from atmosphere, wherein the second piece of the housing forms a cavity having an opening formed by a rim of the second piece of the housing, and wherein the first piece of the housing is a lid that is selectably coupled to the rim of the second piece of the housing to substantially seal the cavity formed by the first piece of the housing from atmosphere; a heat exchange assembly disposed within the housing, the heat exchange assembly comprising a fluid conduit that passes from inside the housing to outside the housing, the fluid conduit being configured to receive a flow of fluid in its gaseous state from a fluid flow generator located outside the housing, the heat exchange assembly being configured to liquefy the flow of fluid received into the heat exchange assembly via the fluid conduit, and wherein the heat exchange assembly is formed integrally or securely with the first piece of the housing; and a fluid storage assembly disposed within the housing, the fluid storage assembly being in fluid communication with the heat exchange assembly, the fluid storage assembly being configured to store fluid that has been liquefied by the heat exchange assembly, and wherein the fluid storage assembly is formed integrally or securely with the second piece of the housing. |
