Cryogenic storage system with improved temperature stability

The present disclosure relates to devices and methods for the storage of material at cryogenic temperatures. Such devices may be useful for storing materials in the vapor space of a cryogenic dewar at a stable temperature and for preventing temperature excursions that may otherwise occur during refilling of a dewar with liquid cryogen. In some implementations, the devices may include a cryogen space holding liquid cryogen and gas, a separate storage space containing only gas, and a separate path for gas to leave the cryogen space during cryogen refills without passing through or substantially disturbing the temperature of the storage space. Some implementations further provide for passage of gas from the cryogen space to the storage space between cryogen refills to improve cryogen utilization efficiency.

Cryogenic storage vessel

A vessel for storing and transporting cryogenic fluids such as liquid helium. The vessel comprises a plurality of elongated containers supported one within another in coaxial circumjacent relation in a manner minimizing heat transmission therebetween, and it further comprises a cooling system forming a temperature barrier that restricts inward migration of heat from the outer to the inner container. Respecting the support system, the inner fluid-receiving container is supported by an encapsulating intermediate heat shield container which in turn is supported by an outer jacket surrounding and enclosing the intermediate heat shield. The support means effecting such interrelationship includes both transverse support structure constraining the containers relative to each other against transverse or radial displacements and longitudinal support structure interconnecting the containers one with another and constraining the same against relative longitudinal displacements at least at one end of the vessel. The transverse support structure constitutes a plurality of structurally independent supports as respects the interconnection of the inner container with the intermediate heat shield and interconnection of the heat shield with the outer jacket; and all of the support structures define restricted thermal flow paths through which heat migration from the outer container to the inner container is sharply limited. Respecting the cooling system, two flow-separated cooling coils surround the heat shield container, one of which carries a coolant such as liquid nitrogen and the other of which connects both with the inner fluid-receiving container and with a delivery system through which fluid is withdrawn from the inner container.

Vacuum separator for dewar flask cold exchange systems

A cold exchange system includes a Dewar flask having an inner vessel and an exterior vessel joined to and surrounding the inner vessel, defining an evacuable chamber therebetween. The flask includes an evacuation port through the inner and exterior vessels through which cryogenic gas contained in the inner vessel can evaporate during the cold exchange process. The exterior vessel includes a device port through which a device to be cooled extends. The device is housed in a housing that is engaged over the device port. A cold finger is in heat transfer contact with the inner vessel. A non-metallic flexible bellows is sealingly adhered to the cold finger at one open end of the bellows. The other open end of the non-metallic bellows is sealingly adhered at its other open end to a top plate which is vacuum fitted over the device port. The non-metallic bellows and device housing define a second evacuable chamber separate from the Dewar flask vacuum chamber. The separation of the vaccum chambers is maintained by the non-metallic bellows and adhesive joints between the bellows and the cold finger and top plate. The device to be cooled is mounted in direct mechanical contact with the cold finger within the device chamber defined by the non-metallic bellows. The joint between the non-metallic bellows and the metallic cold finger and top plate is formed by an adhesive compound essentially containing an admixture of an epoxy with fine grain beads. The beads each generally have the same outer diameter to create a uniform adhesive joint, to insure a vacuum tight seal, and to provide a uniform spacing of the bellows from the aluminum components to insure long-term vacuum integrity of the adhesive joint during repeated thermal cycling.

Closed cycle cryogenic refrigeration system with automatic variable flow area throttling device

An integral combination of expansion valve and evaporator in a cryostat using a single support member. The valve includes two flow orifices, one orifice (62) being used primarily for steady-state operation and the other orifice (44) being used only during cool-down. An actuator (28) having a high coefficient of thermal expansion moves a needle (46) positioned in the cool-down orifice (44) such that a large orifice flow area at the start of cool-down is automatically and continously reduced as the actuator (28) temperature decreases as refrigerant is throttled through the orifice. Within a range of approximately 30K from the desired steady-state evaporator temperature, the needle (46) completely blocks the cool-down orifice (44). Then, refrigerant flows through the steady-state orifice (62) which has a remotely adjustable needle (68). In the final stage of cool-down, the refrigerant system is entirely controlled by the steady-state orifice (62) and its associated needle (68).

Cryogenic liquid storage method and system

A cryogenic liquid storage system and method in which cryogenic liquid is stored within an active cryogenic liquid storage tank and one or more passive cryogenic liquid storage tanks. Headspace regions of the passive cryogenic liquid storage tanks are connected to the active cryogenic liquid storage tank and the active cryogenic liquid storage tank is refrigerated to collapse the headspace vapor within the active cryogenic liquid storage tank causing the flow of headspace vapor from the headspace regions of the passive cryogenic liquid storage tanks to the active cryogenic liquid storage tank. The increased head of liquid produces a pressure differential that drives liquid from the active cryogenic liquid storage tank back to the passive cryogenic liquid storage tanks. In such manner, refrigeration applied to a single active cryogenic liquid storage tank can be used to refrigerate the passive cryogenic liquid storage tanks to prevent the venting of headspace vapor from all of the cryogenic liquid storage tanks.

The second step is to cool the evacuated gaseous vapor present in the condenser to a temperature below the boiling point of the liquid product and above the boiling point of volatile impurities. As a result, the first portion of the evacuated gaseous vapor is condensed and the second portion is not condensed. The last step is to exhaust the second part of the evacuated gaseous vapor from the condenser.

Methods and apparatus to generate liquid ambulatory oxygen from an oxygen concentrator

The present invention is directed to a much safer and less expensive way of providing portable oxygen from a gas concentrator for patients who do not want to be tied to a stationary machine or restricted by present oxygen technology. In one preferred embodiment, the present invention splits off some of the excess capacity gas flow from a gas concentrator which is then stored via liquefaction. The stored gas can then be used as a portable supply. A portion of the oxygen gas flow generated by the oxygen concentrator is channeled to a condenser which receives and liquefies the oxygen gas using cryocooler. A storage dewar is used for storing the oxygen liquefied by the condenser. Liquid is then selectively transferred to a smaller portable dewar. A controller can be used for monitoring the parameters of liquefaction, including oxygen concentration, the amount of liquid oxygen in the dewar, and for controlling the parameters of liquid oxygen generation and transfer. In one embodiment, the flow rate into the condenser is chosen to exceed the capacity of the condenser to minimize the liquefaction of argon, nitrogen and trace gases, and to purge the system. In another embodiment, condenser parameters are controlled in certain ranges and a unique condenser design is also disclosed. Also disclosed is a representative method for controlling the system using a microprocessor with a database and control functions which senses various parameters relating to the liquefaction, provides the microprocessor with the sensed parameters, calculates optimal conditions, and controls the liquefaction process.
