DEVICE FOR KEEPING AND FEED OF CRYOGENIC PRODUCTS Russian patent published in 2002 - IPC

FIELD: keeping of cryogenic products. SUBSTANCE: device has an internal vessel enclosed in a vacuum-tight housing. Adsorbent is positioned on its outer surface. The vacuum-laminated heat insulation is located in the cavity between the inner surface of the housing and the outer surface of the inner vessel with formation of gaps between each surface. Ducts are made in the vacuum-laminated insulation, which communicate the gaps. The ducts consist of sections located in different planes. The duct walls are made of heat-conducting material. EFFECT: reduced time of stabilization of residual pressure in layers of insulation after vessel filling. 1 dwg
