Abstract:
1. A heat exchange module, adapted to be part of a stack of such modules in a heat exchanger, said module comprising two metal sheets welded along weld lines defining between said metal sheets a group of channels disposed side by side substantially in a common plane, at least one said channel extending between two other said channels of the group, said channels being adapted to be passed through by an exchange fluid and, from the fluidic point of view, being in parallel with each other between at least two connection orifices of said module that are laterally separated from each other, said group of channels having a generally U-shaped configuration, wherein each channel connects said connection orifices together independently of the other said channels and wherein said two metal sheets further define between them at least one distribution chamber intercommunicating a corresponding end of said channels with a respective one of said connection orifices of said module; and wherein each of said channels essentially has a continuous cross-sectional area and a constant width between two side edges, each said side edge extending along a respective path defined by a respective weld line comprising two linear segments connected to each other by an arcuate segment.
