Abstract (en)
The heat exchanger fin system, made from corrugated and perforated or slitted metal sheet, has the main direction (F1) of its corrugations (14) lying at an oblique angle to its two lateral edges (13). The general direction (F2) with least resistance to the fluid flow forms a substantial angle with the main direction of corrugation and lies parallel to the lateral edges, while the sides of the corrugations have ridges to promote a transverse fluid movement relative to the general direction of least resistance and to create turbulence.
Abstract (fr)
Cette ailette (9) comprend un produit ondulé perforé et/ou crevé qui présente une direction principale d'ondulation (F1) et qui est délimité par deux bords latéraux (13). La direction principale d'ondulation (F1) est oblique par rapport aux deux bords latéraux (13). Application aux lignes d'échange thermique principales des installations de distillation d'air. <IMAGE>
