The invention relates to a plate and fin heat exchanger for bringing into a heat exchange relationship at least one refrigerant fluid and one calorigenic fluid, having a plurality of plates arranged parallel to a longitudinal direction so as to define a plurality of passages between said plates, at least one passage being formed between two adjacent plates and having at least one heat exchange structure equipped with at least one series of fins extending parallel to the longitudinal direction and following one another in a lateral direction, the fins, within the passage, defining channels for the flow of the fluids. According to the invention, at least one fin, over at least part of its surface, has a surface texturing in the form of striations arranged parallel to the longitudinal direction.
