The casing (2) has a first end wall (3), a second end wall (4), and a peripheral part (5) between the two end walls (3, 4). Each conduit (21 -23) has an inlet and an outlet, where the outlet of the first conduit (21, 23) is connected substantially in series to the inlet of the second conduit (22). The plurality of coiled conduits (21 -23) comprises one third conduit (23) for the first fluid, having turns of diameter greater than the diameter of the turns of the first conduit (21), in such a way that the third conduit (23) forms a helix, within which the helix formed by the first conduit (21 ) extends. The third conduit (23) has an inlet (23a) and an outlet (23b), the outlet (23b) of the third conduit (23) being connected to the inlet (22a) of the second conduit (22) in parallel to the first conduit (21), the second conduit (22) preferably having a flow section larger than the sections of passage of the first and third conduits (21, 23).
