연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

A construction for a multi-layered vacuum super insulated cryogenic tank and a method for making the same is disclosed. The cryogenic tank uses an inner tank that is wrapped with multiple layers of radiation shielding and is suspended within a frame by one or more suspension members. The frame is enclosed within a fluid tight outer tank that fits snuggly against the frame. An ultra-high vacuum is created between the inner and outer tanks.

What is claimed is: 1. A cryogenic storage tank comprising: a fluid tight inner tank operable to store a fluid; a frame extending around all sides of said inner tank, said frame being spaced apart from said inner tank; a fluid tight outer tank surrounding said frame; and a vacuum between said inner and outer tanks. 2. The storage tank of claim 1, further comprising at least one flexible suspension member, said suspension member being connected to said inner tank and connected to said frame, and said suspension member suspending said inner tank within said frame. 3. The storage tank of claim 2, wherein said at least one suspension member is under tensile force when suspending said inner tank within said frame. 4. The storage tank of claim 2, wherein said at least one suspension member is a filament. 5. The storage tank of claim 2, wherein said at least one suspension member is made from at least one of carbon fiber and glass fiber. 6. The storage tank of claim 2, wherein said at least one suspension member is a plurality of suspension members and said suspension members are attached to corners of said inner tank. 7. The storage tank of claim 1, wherein said frame includes at least two members that are connected together to form said frame and to surround said inner tank. 8. The storage tank of claim 7, wherein said at least two members are welded together. 9. The storage tank of claim 1, wherein said outer tank includes at least two members that are connected together to form said outer tank and to surround said frame. 10. The storage tank of claim 9, wherein said at least two members are welded together. 11. The storage tank of claim 1, wherein said frame has a plurality of openings. 12. The storage tank of claim 11, wherein said inner tank and said frame are arranged to provide access to said inner tank through at least one of said openings. 13. The storage tank of claim 1, wherein said inner tank, said frame and said outer tank are non-cylindrical in shape. 14. The storage tank of claim 1, further comprising at least one layer of insulation between said inner tank and said frame. 15. The storage tank of claim 1, wherein said frame is in direct contact with said outer tank. 16. The storage tank of claim 1, wherein said frame is shaped to be complementary to a shape of an entirety of said inner tank. 17. The storage tank of claim 1, wherein said frame supports said outer tank against said vacuum between said inner and outer tanks. 18. The storage tank of claim 1, wherein said outer tank is contoured to be complementary to said frame so that said outer tank fits tightly against said frame. 19. The storage tank of claim 1, wherein said inner and outer tanks are made from at least one of stainless steel, aluminum and an alloy of aluminum. 20. The storage tank of claim 1, wherein said inner tank is operable to store a fluid at less than about 30° K. 21. The storage tank of claim 1, wherein said frame is nested in said outer tank. 22. The storage tank of claim 1, wherein said outer tank is free of attachment to said inner tank. 23. A cryogenic storage tank comprising: a fluid tight inner tank operable to store a fluid; a frame surrounding at least a portion of said inner tank, said frame being spaced apart from said inner tank; a fluid tight outer tank disposed outside of said frame; and a vacuum between said inner and outer tanks, wherein said outer tank is deformed against said frame by said vacuum between said inner and outer tanks. 24. A cryogenic storage tank comprising: an inner tank operable to store a fluid; a frame surrounding an entirety of said inner tank; at least one flexible suspension member connected to said inner tank and connected to said frame, said at least one suspension member suspending said inner tank inside said frame; an outer tank surrounding said frame; a vacuum between said inner and outer tank; and wherein at least one of said inner tank, frame, and outer tank is non-cylindrical. 25. The storage tank of claim 24, wherein said at least one suspension member is a filament. 26. The storage tank of claim 24, wherein said at least one suspension member is made from at least one of carbon fiber and glass fiber. 27. The storage tank of claim 24, wherein said frame has a plurality of openings. 28. The storage tank of claim 24, wherein said inner tank is operable to store a fluid at less than about 30°K. 29. The storage tank of claim 24, wherein said outer tank is deformed against said frame by said vacuum. 30. The storage tank of claim 24, wherein said frame is spaced apart from said inner tank. 31. A cryogenic storage tank comprising: a fluid tight inner tank operable to store a fluid; a frame surrounding at least a portion of said inner tank, said frame being spaced apart from said inner tank; a plurality of suspension members suspending said inner tank from and within said frame; a fluid tight outer tank disposed outside of said frame; and a vacuum between said inner and outer tanks, wherein a suspension force imparted on said frame by said suspension members is borne entirely by said frame. 32. A cryogenic storage tank comprising: a fluid tight inner tank operable to store a fluid; a frame surrounding at least a portion of said inner tank, said frame being spaced apart from said inner tank; a fluid tight outer tank disposed outside of said frame; at least one flexible suspension member, said suspension member being connected to said inner tank and connected to said frame, and said suspension member suspending said inner tank within said frame; and a vacuum between said inner and outer tanks, wherein said inner tank has relatively flat opposite top and bottom surfaces and said at least one suspension member is a plurality of suspension members spaced about said top and bottom surfaces of said inner tank.
