A unit (1, 1') for recovering and converting the thermal energy of the exhaust gases of an internal combustion engine (14) of a vehicle, comprising:
- a heat exchanger (2, 2') including a main conduit (5, 5') arranged branching with respect to and fluid dynamically communicating with an exhaust pipe (4) of said internal combustion engine (14). The unit (1, 1') is characterised in that:
- said main conduit (5, 5') of said heat exchanger (2, 2') has a substantially U-shaped geometry comprising an inlet section (6, 6') and an outlet section (7,7') for the exhaust gases, both fluid dynamically connected (3) to said exhaust pipe (14),
- said heat exchanger (2, 2') is arranged along a transverse direction with respect to said exhaust pipe (4) in such a manner that the flow of the exhaust gases has a motion in the transverse direction away from the exhaust pipe (4) and an approaching motion in the transverse direction towards the exhaust pipe (4) respectively when said flow of the exhaust gases passes through the inlet section (6, 6') and the outlet section (7, 7') of said heat exchanger (2, 2'). |
