DEPHLEGMATOR FOR A GENERATOR OF REFRIGERANT VAPOUR FOR ABSORPTION THERMAL MACHINES, AND GENERATOR COMPRISING SUCH DEPHLEGMATOR

Dephlegmator (1) for a generator (200) of refrigerant vapour for absorption thermal machines, comprising: • - a plurality of tubes (2), wherein each tube (2) comprises a substantially U or C shaped body having a first and a second rectilinear portions (3) extending longitudinally along a direction substantially parallel to a substantially vertical reference axis (X) of the dephlegmator (1), and a central portion (4) which connects said first and second rectilinear portions (3) at their first end (3a), said tubes (2) being devised for circulating inside them a cooling fluid suitable for cooling vapor flows (V) which pass through the dephlegmator (1); • - a plurality of plates (6) which are stacked up in sequence along said reference axis (X) and comprise each a plurality of through holes (7) which are each crossed by a corresponding rectilinear portion (3) of a tube (2), said plates (6) being further configured and mutually arranged between them so as to convey, at least partially, said vapour flows (V) which cross the dephlegmator (1) along the external walls of the rectilinear portions (3) of one or more tubes (2) of said plurality of tubes.
