Heat exchanger having radial support

摘要

A heat exchanger has the tube sections supported by one or more units comprising a cylinder section surrounding the bundle of tube sections and having rods forming a rod baffle attached to each of its two opposing faces. In another embodiment, the tube sections are surrounded along a substantial porton of their length by a shroud cylinder having a plurality of rod baffles attached thereto. The shroud cylinder can be composed of a plurality of cylinder sections having recesses in their opposing faces so that abutting faces of adjacent shroud cylinder sections have facing pairs of recesses which correspond in shape essentially to the shape of the end of the rods of a rod baffle.
