TUBULAR HEAT EXCHANGER FOR RESPECTIVELY HOT AND COLD FLUIDS WITH LARGE DIFFERENCES RESPECTIVELY FROM TEMPERATURE AND PRESSURE.

摘要

The invention relates to a cylindrical calender heat exchanger (1) containing straight fluid passage tubes (6) and attached at its opposite ends to two tubular plates (5) respectively, connected to at least one of these by a flexible connection (7). BR/ Between the flexible connection (7) and the adjacent end of the shell (1) is interposed a rigid coaxial annular joint piece (8) connected respectively to the shell (1) and the flexible connection (7) in being radially inner projecting and section sufficient to minimize the increase of the calender diameter and the displacement of the point of attachment of the flexible connection on the annular part under the effect of the internal pressure. BR/ The invention is applicable to heat exchangers with thin tubular plates and long tubes. / P
