HEAT EXCHANGER, APPLICATIONS FOR VAPORIZATION OF PRESSURIZED LIQUID AND AIR DISTILLATION APPARATUS PROVIDED WITH SUCH AN EXCHANGER

摘要

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 (7) that are substantially parallel to the first direction and comprising at least one redistribution area (5) associated with at least one lateral collector (6) in an intermediate area of the length thereof, in addition to being provided with deviation waves (8) 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 (8) communicate with the exchange waves (7). The deviation waves (8) are essentially as rigid as the exchange waves (7) . The invention can be used with exchangers in pumped air-distillation devices.
