Fabienne Chatel has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Heat exchange fin and the production method thereof
    Patent number: 7445040
    Abstract: 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 exchanger with brazed plates
    Patent number: 7059397
    Abstract: 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—gas heat exchangers.

  • Heat exchanger with brazed plates
    Publication number: 20040144525
    Abstract: The invention concerns a heat exchanger comprising a stack of plates defining passages, containing corrugated fins comprising a transverse section with repeated corrugated pattern extending between two upper and lower end planes. The pattern comprises a base corrugated pattern (M) comprising corrugated legs (13) linked to corrugated summits (16) and corrugated bases (17), said base pattern being modified by a sub-pattern (M1) which defines, between at least some corrugated legs, additional leading edges (20, 21) located at an intermediate level between the planes. The invention is applicable to cryogenic gas-gas heat exchangers.

  • Corrugated fin with partial offset for a plate-type heat exchanger and corresponding plate-type heat exchanger
    Patent number: 6415855
    Abstract: In this corrugated fin, each corrugation leg (10A, 10B) has a notch (18A, 18B) on at least one edge (11A) and over at least part of its height. Application to brazed-plate heat exchangers.
