Abstract

Intercambiador de calor, especialmente para el enfriamiento de gases en un sistema de recirculación de gases de escape. Presenta una pluralidad de tubos paralelos (10) para el flujo de gas, cada uno provisto de corrugaciones helicoidales (11); dichos tubos (10) tienen un diámetro exterior de entre 7,5 mm y 10,5 mm, y las corrugaciones helicoidales (11) forman un ángulo (a) de entre 5° y 25° con un plano perpendicular al eje del tubo (10). Tiene prestaciones equivalentes a las de intercambiadores conocidos, a un coste significativamente menor.
