A heat-exchange module has a main exchanger and at least one secondary exchanger,
each having a body with fluid-circulation tubes, and cooling fins, the secondary
exchanger being fixed onto the main exchanger. The module includes a set of fins
common to the main exchanger and to at least one secondary exchanger, these fins
being mounted on the tubes of the main exchanger and projecting from this exchanger,
the projecting parts of the fins including cut-outs for accommodating the tubes
of the secondary exchanger. Fastenings secure the secondary exchanger in the position
in which its tubes are engaged in the cut-outs.
