Abstract

Módulo intercambiador de calor para un sistema de recirculación de gases de escape. Comprende un intercambiador de calor (1) con unos conductos (11) destinados al flujo de los gases con intercambio de calor con un fluido de refrigeración; se caracteriza porque comprende además al menos un conducto en derivación (12), integrado en el intercambiador (1), adecuado para hacer circular los gases de escape sin que sufran un enfriamiento sustancial. Preferiblemente, el módulo comprende además medios (2) de selección del recorrido de los gases de escape, formados por una válvula de tres vías integrada en el módulo y un detector de la temperatura de los gases. Con una ocupación mínima de espacio y gran simplicidad constructiva, permite enfriar los gases de escape sólo selectivamente, manteniendo un nivel mínimo de emisión de contaminantes.Heat exchanger module for an exhaust gas recirculation system. It comprises a heat exchanger (1) with ducts (11) intended for the flow of gases with heat exchange with a cooling fluid; It is characterized in that it also comprises at least one bypass duct (12), integrated in the exchanger (1), suitable for circulating the exhaust gases without suffering substantial cooling. Preferably, the module further comprises means (2) for selecting the path of the exhaust gases, formed by a three-way valve integrated in the module and a gas temperature detector. With a minimum occupation of space and great constructive simplicity, it allows cooling the exhaust gases only selectively, maintaining a minimum level of emission of pollutants.
