Abstract

La invención de interés se refiere a un tubo intercambiador de calor de metal (1), que comprende aletas integrales (2) formadas en el exterior del tubo y que tiene una base de aleta (3), flancos de aleta (4) y una punta de aleta (5), donde la base de la aleta (3) sobresale radialmente de la pared del tubo (10), y se forma un canal (6) que tiene un fondo de canal (61) entre las aletas (2), en cuyo canal se forman estructuras adicionales (7, 71, 72) espaciados entre sí. Las estructuras adicionales (7, 71, 72) dividen el canal (6) entre las aletas (2) en segmentos (8). Las estructuras adicionales (7, 71, 72) reducen localmente el área de la sección transversal por medio del cual puede pasar el flujo en el canal (6) entre dos aletas (2) y al menos limitan el flujo de fluido en el canal (6) durante la operación. Las primeras estructuras adicionales (7, 71) son proyecciones (71) que parten del fondo del canal (61) y se dirigen radialmente hacia afuera, cada una de las cuales está limitada en la dirección radial por una superficie de terminación (713) ubicada entre el fondo del canal (61) y la punta de la aleta (5), definiendo así una extensión radial de los resaltes (71). En el lugar de los salientes (71) están dispuestos salientes de material radialmente exteriores (72) como segundas estructuras adicionales (7, 72), cuyos salientes están formados por el material de los flancos de aleta (4). Cada uno de los salientes de material (72) está dispuesto entre una superficie de terminación (713) y el pico de la aleta (5) en la dirección radial, de modo que los salientes de material (72) se forman alrededor de la extensión radial de los salientes (71) sobre el fondo de canal (61) del canal (6), que se encuentra lateralmente sobre el flanco de aleta (4). Las protuberancias de material (72) se extienden más en la dirección axial y radial que en la dirección circunferencial.
