<p>PURPOSE:To prevent a roll over in a low temperature liquid storage tank, by opening both upper and lower ends of a heat exchanger, forming cross sectional area of the heat exchanger smaller in its lower part while larger in its upper part and arranging said heat exchanger in the storage tank. CONSTITUTION:A horn shaped heat exchanger 10, in which a lower end opening is narrowed and cross sectional area is spread increasing gradually toward an upper end opening, is arranged in a cylindrical low temperature liquid storage tank T. If high temperature liquid, slightly at higher temperature than of liquid in a low temperature liquid tank 2 further with larger specific gravity than said liquid, is injected through a pipe line P, a high temperature liquid layer 3 is formed to a lower layer in the storage tank T, and a low temperature liquid layer 2 is overlapped on the layer 3, fianlly only a low temperature liquid layer 2' in the heat exchanger 10 is lifted by the high temperature liquid layer 3, thus thickness of the liquid layer is gradually reduced. As a result, heat exchanging area, separately contacted with an external wall of the heat exchanger 10, between the high temperature liquid layer 3 and low temperature liquid layer 2, is particularly increased, and a thermally stable neutral condition can be generated in the storage tank T.</p> |
