A heat exchanger (10) having at least a heat exchange unit (20, 22) comprises a first circuit having a plurality of first passage ways in which a first fluid is able to flow, along a predetermined direction (S), and a second circuit (26, 44) in which a second fluid is able to flow. The second circuit (26, 44) is provided with a plurality of second passage ways (29, 46) in which the second fluid is able to flow. Each first passage way and/or each second passage way (29, 46) defines a substantially obligatory path for the first and/or second fluid from a relative entrance (29a, 46a) to a relative exit (29b, 46b). The combination of the obligatory paths substantially covers the whole heat exchange surface of the first circuit and/or the second circuit (26, 44).
