Heat-exchange fin for a brazed-plate heat exchanger, and corresponding heat exchanger

摘要

A fin (9) includes a perforated and/or recessed corrugated product which has a main direction of corrugation (F1) and which is bounded by two lateral edges (13). The main direction of corrugation (F1) is oblique with respect to the two lateral edges (13). The fin is useful in the main heat-exchange lines of air distillation plants.
