PURPOSE:To minimizing transmitting heat into the tank, by jointing both edges inserting an intermediate shell between the upper edge of the lower shell extended from the bottom plate of outer tank and the lower edge of the upper shell extended from the bottom plate of inner tank. CONSTITUTION:An upper plate 13 and a lower plate are fixed on the counter surfaces to the inner tank pressure proof material 8 and the outer tank pressure proof material 7, a shell 15, 16 are fixed to the upper and lower plate 13, 14 respectively as supporting shell block to cover the former with the latter overlapping, and extended up and downwards, the intermediate shell 17 corresponding to the overlapping section h joints flange 18, 19 fixed to the upper and lower edges to the upper and the lower edge 20, 21 of the shell 15, 16 in a body. Thereby, the shell 15, 16, 17 are used for labyrinth course with vent section, and as it has more than double as long as the height between the inner and outer tank materials 7, 8. Heat which transmits into the tank can be limited, adiabatic effect increases. |
