Filed:

Mar 4, 1999

Appl. No.:

9/262796

Inventors:

Tibor I Lak - Huntington Beach CA

International Classification:

F17C 502

US Classification:

62 471

Abstract:

A cryogenic liquid heat exchanger system has a subatmospheric pressure reservoir, a tube, and an initial fluid ejector. The sub-atmospheric pressure reservoir has a vacuum exhaust. The tube extends through the reservoir. The initial fluid ejector has a suction chamber inlet that is functionally connected to the reservoir vacuum exhaust. The system may have a plurality of fluid ejectors connected to one or more exhausts either in series or parallel. The initial fluid ejector may receive one or more pressurized fluid streams, and the streams may be steam. A process for generating sub-atmospheric pressures in a cryogenic fluid heat exchanger reservoir includes the step of discharging an initial fluid stream into an initial fluid ejector having a suction chamber functionally connected to an exhaust of the reservoir. A process for generating sub-atmospheric pressures in a cryogenic fluid heat exchanger reservoir includes the step of using a fluid ejector to reduce the pressure in the reservoir. In either process, cooling cryogenic fluid is directed through the reservoir.

F25B 1900

US Classification:

62 461

Abstract:

A system and method for cooling a first cryogenic liquid in a vessel comprises the steps of directing a second cryogenic into the first cryogenic fluid and releasing gas from the vessel. The first cryogenic fluid has a boiling point that is higher than the boiling point of the second cryogenic fluid. Directing the second cryogenic fluid into the first cryogenic fluid results in the second fluid cooling the first fluid and the second fluid vaporizing. The vaporized fluid is released as a gas from the vessel. The vessel may be a propellant tank for a space vehicle. The first and second cryogenic fluids are delivered from supplies located outside of the vehicle. The first cryogenic liquid may be oxygen and the second cryogenic liquid may be nitrogen, neon, or helium. In another aspect of the invention, the first cryogenic liquid may be hydrogen and the second cryogenic liquid may be helium.

US Classification:

62 541

Abstract:

Slush is made from a liquid using slush making systems or according to slush making processes. A jacketed vessel of the processes and the systems has an interior wall that defines an interior space. The interior space comprises a top and a bottom. The interior space has an average overall cross-sectional area taken through a vertical axis extending generally between the top and the bottom. The interior space also has a collection portion having an average collection portion cross-sectional area taken through the vertical axis that is less than the average overall cross-sectional area. The liquid is placed into the interior space and the interior walls are cooled. Slush forms on the interior walls and migrates to the collection portion. The collection portion is located at the interior space bottom when the slush density is higher than the liquid density and the collection portion is located at the interior space top when slush density is less than the liquid density. To facilitate the migration of the slush to the collection portion, at least a conical portion of the interior space has the general shape of a cone and the collection portion is located in the proximity of an apex of the conical portion, thereby helping to funnel the slush to the collection portion.

Abstract:

A cryogenic propellant tank system and process for densifying cryogenic liquid propellant comprises a tank with a combined manifold, a combined manifold line, a pressurizing gas line, and a vent line. The combined manifold is located in the tank. The combined manifold line functionally connects the combined manifold to a chilling system. The pressurizing gas line and the vent line are also functionally connected to the combined manifold line. The tank may be disposed in a vehicle. The manifold is disposed proximate the top of the tank. The chilling system may be a heat exchanger/filling system. The process for filling the tank comprises the steps of charging the tank with cryogenic liquid propellant, venting gases in the tank, densifying the cryogenic liquid propellant, and pressurizing the tank. The tank is charged with the cryogenic liquid propellant such that the orifices in the combined manifold are submerged. The gases in the tank are vented through the combined manifold and out of the tank.
