Method for assembling a tube module, a tube module, and a heat exchanger provided with such a tube module.

摘要

The invention relates to a method for assembling a tube module which comprises a number of layers of tubes which are received in grid-like manner in protecting members arranged spread along the length of the tubes, comprising the steps of: i) assembling a first layer of tubes on protecting member supports; ii) arranging a tube comb at the height of the supports transversely over the first layer of tubes, wherein comb teeth extend between adjacent tubes; iii) displacing tubes over the flat side of the tube comb remote from the comb teeth to form the second layer of tubes; iv) repeating steps ii) and iii) until the number of tube layers is obtained; and v) mutually fixing the tube combs while forming a protecting member, to such a tube module and to a heat exchanger. <IMAGE>
