Abstract

A heat exchanger (1) for gases, in particular for the exhaust gases of an engine, comprising a bundle of tubes (2) arranged inside a casing (3), intended for the circulation of the gases in order to exchange heat with a coolant, at least one gas tank (6) that can be fitted to one end of the casing (3) and connected to the gas recirculation line, and a particle filter (7) for filtering the exhaust gases, associated with said gas tank (6). Said filter (7) is incorporated into the gas tank (6) and forms a single inseparable part that can be fitted to the casing (3) of the exchanger (1). Preferably, the filter (7) is incorporated into the gas tank (6) by welding. A filter which is fully incorporated into the gas tank in a single part is obtained, which therefore facilitates the assembly thereof to the exchanger casing.
