Abstract

1.Perfeccionamientos introducidos en un tubo aleteado para intercambiador de calor o similar, que tiene aletas en forma de "T" en el lado exterior del tubo, que corren circunferencialmente alrededor del tubo, extendiéndose la base de las aletas esencialmente de manera radial desde la pared del tubo y aproximándose los extremos exteriores de las aletas a los extremos exteriores aletas adyacentes, caracterizados porque las aletas corren circunferencialmente alrededor del tubo de manera continua, siendo uniforme la configuración en "T" e ininterrumpida en torno a la circunferencia del tubo. 2.Perfeccionamientos, según la reivindicación 1, caracterizados porque la distancia entre aletas en dirección radial, desde la pared del tubo, aumenta continuamente y luego disminuya en la región de los extremos de las aletas. 3.Perfeccionamientos, según una de las reivindicaciones 1-2, caracterizados porque las aletas rodean al tubo con un solo hilo o con múltiples hilos , y circundan al tubo helicoidalmente. 4.Perfeccionamientos, según las reivindicaciones 1 ó 2, caracterizados porque las aletas corren circunferencialmente en forma anular. 5.Perfeccionamientos, según una de las reivindicaciones 1 a 4, caracterizados porque hay entre dos y veinte aletas dispuestas por centímetro. 6.Perfeccionamientos, según una de las reivindicaciones 1 a 5, caracterizados porque la anchura de la hendidura superior es igual a 0-1-1,0 milímetro. 7.Perfeccionamientos introducidos en un tubo aleteado para intercambiado de calor.
