    摘要： A heat exchanger (1) comprises a casing (2, 13, 28, 33), within which there is present a first pipe wound in a spiral (25), in which a first fluid flows, the casing (2) being designed to receive a second fluid that is in heat-exchange relationship with the first fluid. The heat exchanger further comprises at least one second pipe wound in a spiral (26, 27), which connects, in parallel to the first pipe (25), two gaps (15, 36) formed in the casing (2, 13, 28, 33), the spiralled pipes (25,26, 27) being arranged in a coaxial way and at a distance from one another, and having different sections of passage.

    摘要： A heat exchanger (1) has an exchanger unit (20), comprising at least one first coiled conduit and one second coiled conduit (21 -23) that are substantially coaxial, and a casing (2) for housing the exchanger unit (20). 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).
