Abstract: The invention is related to a heat exchanger (1), which comprises: at least one column of parallel tubes (2) which are arranged in a stack and which define a longitudinal direction; a housing (3) inside which the tubes (2) are housed, the tubes (2) being separated from one another, so as to configure a channel for the passage of cooling fluid consisting of: passage sections (4) between tubes (2) that are contiguous in the direction of the stack; passage sections (5) between tubes and housing (3); and baffles (6, 7) that deflect the cooling fluid. According to the invention, the baffles are at least two lamellar bodies (6, 7) of a single piece arranged in a plane perpendicular to the longitudinal direction.

Abstract: A heat exchanger (1) for gas, in particular the exhaust gases of an engine, comprising a bundle of tubes arranged inside a shell (2) and intended for the circulation of gas with an exchange of heat with at least one stream of refrigerant fluid, said tubes being fixed by their ends between two support plates (5) coupled at each end of the shell (2), and deflection means arranged inside the shell (2) able to direct the at least one stream of refrigerant fluid inside the shell (2). The deflection means comprises a longitudinal deflector (6, 6a) substantially parallel to the tube bundle and intended to divide the shell (2) into two circuits, said deflector (6, 6a) being fixed by its longitudinal edges to the internal walls of the shell (2) and by its transverse edges to the two support plates (5) by welding. This ensures more effective mounting of said deflector inside the exchanger.

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.
