The heat exchanger can be used for the vaporization of a pressurized liquid and comprises at least one passage way (P) for a liquid extending in a first direction, being provided with exchange waves that are substantially parallel to the first direction and comprising at least one redistribution area associated with at least one lateral collector in an intermediate area of the length thereof, in addition to being provided with deviation waves extending in at least one second direction forming an angle with the first direction, whereby the redistribution area takes up the entire width of the passage way, in a crosswise position with respect to the first direction, whereby the deviation waves communicate with the exchange waves. The deviation waves are essentially as rigid as the exchange waves. The invention can be used with exchangers in pumped air-distillation devices.
A brazed-plate heat exchanger, of the type comprising at least one fluid passage (P′) 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),
