Abstract

Procedimiento para fabricar un tubo aleteado para intercambiador de caloro similar, que tiene aletas que corren circunferencialmente en el lado exterior del tubo, extendiéndose la base de las aletas, en esencia, en dirección radial desde la pared del tubo y aproximándose los extremos exteriores de las aletas a los extremos exteriores de aletas adyacentes, según el cual el material de las aletas se obtiene por desplazamiento del material que constituye la pared del tubo, cuyo material es desplazado en dirección hacia fuera por un proceso de laminación y porque el tubo, merced a la energía de laminación, es puesto en rotación y empujado o solamente es empujado, de acuerdo con las aletas formadas, por lo que se obtienen aletas de altura creciente a partir de la parte del tubo lisa, por lo demás sin formar, caracterizado porque los extremos de las aletas, de forma que los extremos de las aletas alisadas que encuentran a lo largo de un cilindro imaginario que es coaxial con el eje geométrico medio del tubo y porque, subsiguientemente, los extremos de las aletas alisadas son ranurados en dirección circunferencial respecto al tubo y son curvados hacia un lado.
