Abstract: A heat exchanger uses engine exhaust gases. The heat exchanger comprises a plurality of parallel tubes arranged inside a header and through which the gases to be cooled by exchange of heat with a coolant flow, and fins that disturb the flow of the gas and that are arranged inside each tube. The tubes and the header comprise a plurality of protrusions and respectively, the distribution pattern and dimensions of which are defined according to the dimensions of the tubes and of the header and which are able to guarantee suitable distribution of the compression between the header, the tubes and the fins relative to one another while the heat exchanger is being assembled and brazed in the furnace.

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.
