Process for manufacturing a heat exchanger of the type with a nest of tubes formed of concentric layers of wound pipes between a central core and an outside covering, means of distributing and/or collecting fluid at both ends of the nest of tubes, as well as means for transferring fluid longitudinally in the interstitial space between the wound pipes, in which the core is placed in the space with its axis vertical, and the pipes, previously out to the required length, attached at one end in a distribution or collection system, wound round the said core by means of a rotary movement and a translation movement in relation to the core, and attached at the other end to the other collection and/or distribution device respectively.
