Abstract: A heat exchanger (1) for gases, in particular for the exhaust gases of an engine includes a bundle of tubes (2) arranged inside a casing (3) defining a gas inlet (4) and outlet (5). The tubes (2) being intended for the circulation of the gases with a view to exchanging heat with a coolant, and the tubes (2) being distributed in at least one column having a plurality of rows defining a plurality of spaces (8) between the rows, and including a coolant inlet pipe (9) and outlet pipe (10) connected to the casing (3). The exchanger (1) includes a bypass channel (11) incorporated into the casing (3) capable of connecting the spaces (8) defined between the rows of tubes (2) located in front of the channel (11) with one of the coolant pipes (10), in such a way as to improve the distribution of the coolant.

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.
