Abstract

Elemento metálico (2) atravesado por un flujo de aire, que comprende una pared longitudinal superior (6a), unapared longitudinal inferior (6b) y dos paredes laterales (6c), así como una pluralidad de aletas (5), al menos una delas paredes longitudinales (6a, 6b) está formada por una sucesión de placas, caracterizado porque las citadasplacas están unidas una a otra por unión solidaria (23) y porque una primera placa (13) está situada entre dos aletas(5, 5'), estando materializada la intersección entre esta placa (13) y las dos aletas (5, 5') por un primer pliegue (17) yun segundo pliegue (18), porque una segunda placa (15) está situada entre dos aletas (5", 5"'), estandomaterializada la intersección entre esta segundo placa (15) y las dos aletas (5", 5"') por un tercer pliegue (21) y uncuarto pliegue (22), y porque la citada unión solidaria (23) entre dos placas (13, 15) contiguas se sitúa entre elsegundo pliegue (18) y el tercer pliegue (21).Metal element (2) crossed by an air flow, comprising an upper longitudinal wall (6a), a lower longitudinal wall (6b) and two side walls (6c), as well as a plurality of fins (5), at least one of them Longitudinal walls (6a, 6b) is formed by a succession of plates, characterized in that said plates are joined to each other by solidarity connection (23) and that a first plate (13) is located between two fins (5, 5 '), the intersection between this plate (13) and the two fins (5, 5 ') being materialized by a first fold (17) and a second fold (18), because a second plate (15) is located between two fins (5 ", 5 "'), the intersection between this second plate (15) and the two fins (5", 5 "') by a third fold (21) and a fourth fold (22), and because the said joint joint (23) between two adjacent plates (13, 15) it is placed between the second fold (18) and the third fold (21).
