Abstract:
A brazed-plate heat exchanger, of the type comprising at least one fluid passage (Pâ€²) extending in a first direction, provided with exchange fins (7) substantially parallel to the first direction and comprising, in an intermediate area of its length, at least one redistribution zone (5) associated with at least one lateral collector (6) and provided with deflection fins (8) extending along at least a second direction forming an angle with the first direction, this redistribution zone occupying the entire width of the passage, crosswise to the first direction, the deflection fins (8) all communicating with exchange fins (7),wherein the deflection fins (8) have substantially the same stiffness as the exchange fins (7) and the exchange fins (7) are associated with a structure (10) generating pressure loss located upstream and/or downstream of the redistribution zone (5).
