Abstract

Un intercambiador de calor (10) preferentemente proporciona enfriamiento supercrítico al refrigerante de una disposición de enfriamiento transcrítica (12). El intercambiador (10) incluye un par de colectores alargados (20, 22) que tienen ejes geométricos longitudinales (24, 26) dispuestos sustancialmente paralelos entre sí, una pluralidad de tubos alargados (28) espaciados en relación colateral según los ejes geométricos longitudinales (24, 26) de los colectores (20, 22), y aletas en serpentina (30) dispuestas entre pares adyacentes de los tubos. Cada uno de los tubos (28) tienen un primer extremo (31) conectado al colector (20) y un segundo extremo (32) conectado al otro colector (22) de los colectores (20, 22). Cada uno de los tubos (28) está plegado sobre sí mismo para definir por lo menos dos patas paralelas (36) de los tubos (28) de modo que el refrigerante fluya en serie a través de por lo menos dos pasajes de fluido paralelos (38) del colector (20) al colector (22). Cada uno de los tubos (28) tiene una sección transversal aplanada, y las patas paralelas (36) de cada uno de los tubos (28) están preferentemente espaciados entre sí, con la dimensión mayor D de cada una de las patas paralelas dispuesta en un plano común. Preferentemente, cada una de las aletas en serpentina (30) tiene un ancho transversal W dispuesto a través de las patas paralelas (36) de los tubos adyacentes (28). Cada una de las aletas (30) incluye una pluralidad de apéndices alternados (40) y separaciones alargadas (42) dispuestas paralelamente a las patas paralelas (36) y ubicadas entre las patas paralelas (36) de los tubos adyacentes (28) para dividir el ancho W de cada aleta (30) en dos o más elementos de aleta (44) separados que están conectados entre sí por los apéndices (40). Cada uno de los elementos de aleta (44) corresponde a y está dispuesto a lo largo de una de las patas paralelas (36) de cada uno de los tubos adyacentes (28).A heat exchanger (10) preferably provides supercritical cooling to the refrigerant of a transcritical cooling arrangement (12). The exchanger (10) includes a pair of elongated manifolds (20, 22) having longitudinal geometric axes (24, 26) arranged substantially parallel to each other, a plurality of elongated tubes (28) spaced in collateral relationship along the longitudinal geometric axes ( 24, 26) of the manifolds (20, 22), and serpentine fins (30) arranged between adjacent pairs of the tubes. Each of the tubes (28) has a first end (31) connected to the manifold (20) and a second end (32) connected to the other manifold (22) of the manifolds (20, 22). Each of the tubes (28) is folded on itself to define at least two parallel legs (36) of the tubes (28) so that the refrigerant flows in series through at least two parallel fluid passages ( 38) from the manifold (20) to the manifold (22). Each of the tubes (28) has a flattened cross section, and the parallel legs (36) of each of the tubes (28) are preferably spaced apart, with the largest dimension D of each of the parallel legs arranged in A common plane. Preferably, each of the serpentine fins (30) has a transverse width W arranged through the parallel legs (36) of the adjacent tubes (28). Each of the fins (30) includes a plurality of alternating appendages (40) and elongated separations (42) arranged parallel to the parallel legs (36) and located between the parallel legs (36) of the adjacent tubes (28) to divide the width W of each fin (30) in two or more separate fin elements (44) that are connected to each other by the appendages (40). Each of the fin elements (44) corresponds to and is disposed along one of the parallel legs (36) of each of the adjacent tubes (28).
