Abstract

Un tubo metálico que tiene un régimen mejorado de transmisión del calor a o desde un fluido que circula en su interior, caracterizado porque tiene una o más aletas exteriores y una pluralidad salientes o nervios helicoidales interiores de arranques múltiples, enterizos, que se extienden radialmente hacia dentro desde la pared interior del tubo, teniendo dicha pluralidad de salientes helicoidales interiores en ángulo de avance de menos de 60º (medido desde una perpendicular al eje geométrico del tubo), estando configurada dicha pared interior de dicho tubo de modo que defina, en un perfil de sección longitudinal, una parte plana intermedia entre salientes interiores adyacentes, teniendo dichos salientes un perfil de sección transversal que incluye una par de límites laterales que se conectan con las partes planas de la parte interior del tubo entre pares adyacentes de salientes y las puntas de los salientes, estando formados dichos límites laterales por partes cóncavas y convexas que se conectan en un punto de inflexión radialmente hacia fuera de la punta y a una distancia de la punta que es menor que la altura del saliente.
