A heat exchange assembly (10) has a single heat exchanger (15) consisting of a condensation section (16) and an undercooling section (17); the condensation section (16) is provided with a first inlet (23) and a first outlet (25) for a coolant flow, and with a second outlet for a cooling liquid suitable to cause such coolant flow to condense; the undercooling section (17) is provided with a third inlet (29) and a third outlet (33) for a condensed coolant flow, and with a fourth inlet (35) and a fourth outlet (40) to undercool the condensed coolant flow; the third inlet (29) communicates with the first outlet (25) so as to channel at least part of the coolant flowed out of the condensation section (16), whereas a branch-off line (36) is provided in order to draw a part of coolant condensed by the condensation section (16) and have it flow to the fourth inlet (35) through a lamination valve (37).
