ABSTRACT:
A heat exchanger is described wherein a tube bundle comprising a plurality of tubes having convolutions of different radii on a common axis is provided with at least one spacer structure for supporting the tubes in spaced relation. The spacer structure comprises a plurality of parallel bars arranged in pairs and in which semi-circular recesses are formed in abutting surfaces to accommodate the convolutions of the tubes. The bars in adjacent pairs have facing surfaces in an interfitting configuration with clearances therein sufficient to accommodate thermal expansion differences in the adjacent tubes.
