Heat exchanger for indirect heat transfer between primary and secondary mediums, has flow interrupter that is provided for influencing pressure loss in casing space between tube sheets

摘要

The heat exchanger (1) has a casing space (I) provided for receiving primary medium (M). The tube bundles (15) having tubes (10) is provided for receiving the secondary medium (M'). The tube bundles are wound in tube sheets (100-102) around a core tube (20). The spacers are provided for supporting the tube sheets. The flow interrupter (40) is provided for influencing a pressure loss in the casing space between the tube sheets. The flow interrupter is made up of PTFE.
