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.Heat exchanger, especially for cooling gases in an exhaust gas recirculation system. It has a plurality of parallel tubes (10) for the flow of gas, each provided with helical corrugations (11); said tubes (10) have an outside diameter of between 7.5 mm and 10.5 mm, and the helical corrugations (11) form an angle (a) of between 5 ° and 25 ° with a plane perpendicular to the axis of the tube ( 10). It has benefits equivalent to those of known exchangers, at a significantly lower cost.
