A media pathway (1) suitable for use in an opposed bayonet heat exchanger is formed in the annulus (2) between a pair of substantially concentric tubes (3, 4) by the provision of a pair of spaced baffles (5, 6) extending along the annulus so as to divide the annulus into two substantially arcuate chambers (2a, 2b). The spaced baffles are each formed as a flaring in the wall of one of th tubes which projects across the annulus. |
