An exhaust heat exchanger for an exhaust gas recirculation system, including a first flow path for the intake air for an internal combustion engine, a second flow path for the exhaust of an internal combustion engine, and a housing enclosing the first and second flow paths. The first and second flow paths are each divided into a plurality of flow channels in heat-conducting, metallically connected contact with each other, and the flow channels include elements promoting heat exchange between the flow channels.

Exhaust heat exchanger

A heat exchanger including flat tubes having cooling passages for a gas and a bypass for the gas separate from the cooling passages, and coolant channels defined between every two flat tubes adjacent the tube passages and spaced from the bypass of the tubes. The tubes define a cooled area adjacent the passages and an uncooled area adjacent the bypass substantially spaced from the channels.
