Abstract
The present invention discloses an ultra-low temperature component low-thermal elasticity-conductive supporting body. It is characterized by that it includes two conical springs made of supporting material, between large ends of said two conical springs a metal ring is connected, and small end of every conical spring is respectively connected with a supporting metal ring. Said invention also can be one conical spring, its large end is connected with a metal ring and its small end is connected with a supporting metal ring.
Description
Technical field
The invention belongs to a kind of low-temperature superconducting technology, specifically be a kind of in superconductor technology and cryogenic technique supporting structure between the different warm area parts.
Background technique
In superconductor technology and cryogenic technique, usually can relate to the heat load problem that supporting structure is brought between the parts of different warm areas (normally liquid helium warm area and liquid nitrogen temperature).Usually adopt nonmetallic material to replace metallic material, and in fact can be used on the nonmetallic material that have certain intensity under the cryogenic conditions, thermal conductivity under its low temperature and metallic material are approaching.According to
As can be known: the heat conduction amount of material and the length of material are inversely proportional to, be directly proportional with the cross-sectional sizes of material, reducing heat conduction amount can consider from reducing cross-sectional sizes increase bearing length two aspects, but reduces the restriction that the cross section is subjected to support strength and rigidity, is actually very limited and increase length.Because in the cryogenic technique, in order to reduce heat load, all do the general structure of system as far as possible little usually, it is impossible in most of the cases increasing length.
Summary of the invention
The purpose of this invention is to provide a kind of low heat conductive elastic support body of super low temperature part, not only efficiently solving under the prerequisite of the volume that does not increase Cryo Equipment increases the length that supports, and the support thermal distortion of simultaneously can absorbing member expanding with heat and contract with cold and bringing.
Technological scheme of the present invention is as follows:
Low heat conductive elastic support body of super low temperature part is characterized in that comprising two volute springs of being made by blocking materials, connects by metal ring between the major part of two volute springs, and the microcephaly of volute spring is connected with the support metal ring respectively.
Described support is characterized in that described support metal ring is embedded with ceramic ring.
Described support is characterized in that described two support metal ring diameters are identical.
Low heat conductive elastic support body of super low temperature part is characterized in that it being a volute spring of being made by blocking materials, and the major part of volute spring is connected with metal ring, and the microcephaly of volute spring is connected with the support metal ring.
Described support is characterized in that described support metal ring is embedded with ceramic ring.
By welding, perhaps, spring end is stuck in the annular groove between metal ring, support metal ring and the volute spring at the end open loop groove of metal ring, support metal ring.
The present invention is a shape of strut being made volute spring, and two volute springs just form the parts that two broad in the middle is little by the metal ring of centre.The parts of two different warm areas, on one is supported on volute spring by the intermediate metal ring the major part, one is supported on the microcephaly of volute spring by the support metal ring (ceramic ring) that passes volute spring, the physical length of Zhi Chenging is the length of spring spring silk like this, and the spring silk has increased its actual enabling capabilities after making spring, can do the spring silk thinner, further reduce the heat conduction amount that supports again.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Low heat conductive elastic support body of super low temperature part, comprise two volute springs of making by blocking materials 1, connect by metal ring 2 between the major part of two volute springs 1, the microcephaly of volute spring 1 is connected with support metal ring 3 respectively, and support metal ring 3 is embedded with ceramic ring 4.
If the parts of two warm areas all are tubular parts, support then of the present invention can be located immediately between the two support metal rings 3, and ceramic ring 4 can further reduce the capacity of heat transmission of support of the present invention.
