Abstract (en)
[origin: EP1136780A2] A pipe within pipe heat exchanger (10) construction is provided, in which one or more liner tubes (14) are positioned within a shell tube (12), with fluid flow in the liner tube(s) (14) and a different temperature fluid flowing in the space between the liner tube(s) (14) and the shell tube (12). Locations of reduced resistance to bending are provided at one or more locations in one or both of the liner tube(s) (14) and the shell tube (12). One or more heat transfer structures may be affixed in thermally conductive contact to the outer surface of the liner tube (14), to facilitate heat transfer between the "inner" fluid flow and the "outer" fluid flow. <IMAGE>
