A heat exchange fin spacer. The fin may be sandwiched between two plates in a brazed-plate heat exchanger. The fin is based upon a corrugated product having wave legs which, when mounted, define flow channels for a gas to be condensed. The fin has at least one condensed liquid drainage channel on the wave legs and deviation elements that drain the liquid towards at least one lateral edge of the wave legs. The deviation elements are provided with at least one leading edge and/or at least one inclined trailing edge. The invention is suitable for use in the main heat exchanger of an air separation unit.

Heat exchange fin and the production method thereof

The invention concerns a heat exchanger which includes a stack of plates defining passages, containing corrugated fins which include a transverse section with repeated corrugated pattern extending between two upper and lower end planes. The pattern includes a base corrugated pattern that includes corrugated legs linked to corrugated summits and corrugated bases, this base pattern being modified by a sub-pattern which defines, between at least some corrugated legs, additional leading edges located at an intermediate level between the end planes. The invention is applicable to cryogenic gas&#x2014;gas heat exchangers.
