Abstract

Intercambiador termico para proporcionar enfriamiento supercritico al refrigerante de un sistema de enfriamiento transcritico (12) que incluye un par de cabezales alargados (20, 22) una pluralidad de tubos alargados (28) separados en relacion de lado a lado a lo largo de ejes longitudinales (24, 26) de los cabezales (20, 22) y aletas de serpentin (30) que se extienden entre pares adyacentes de los tubos. Cada uno de los tubos (28) es plegado sobre si mismo para definir por lo menos dos patas paralelas (36) de los tubos (28) y tiene una seccion transversal aplanada. Las patas paralelas (36) de los tubos (28) estan separadas de manera preferible una de otras, con la dimension mayor D de cada una de las patas paralelas que se ubica en un plano comun. Cada una de la aletas (30) incluye lenguetas (40) y separaciones alargadas (42) alternadas que se extienden paralelas a las patas paralelas (36) y ubicadas entre las patas paralelas (36) de los tubos adyacentes (28) para dividir la anchura (W) de cada aleta (30) en elementos de aleta discretos (44) que estan conectados entre si por medio de las lenguetas (40). Cada uno de los elementos de aleta (44) se extienden a lo largo de una de las patas paralelas (36) de los tubos adyacentes (28).
