HEAT EXCHANGER WITH IMPROVED DEICING

The present invention relates to a heat exchanger (1) comprising: - at least two fins (5, 5', 5"); - at least two means (3) for guiding the flow of a fluid which are arranged relative to one another in such a manner that the fins (5, 5', 5") can be arranged totally or partially between said at least two means (3) for guiding the flow of a fluid, so as to be capable of allowing the guidance of the flow of an air stream circulating between said means (3) for guiding the flow of a fluid, each means (3) for guiding the flow of a fluid comprises at least one leading edge (34), the leading edges (34) defining with two adjacent fins (5, 5', 5") the inlet of a circulation channel of said air stream, characterized in that the distance separating the end of a fin (5, 5', 5") from a leading edge (34) is distinct from the distance separating the end of an adjacent fin (5, 5', 5") from the same leading edge (34).
