The present invention provides an exhaust gas waste heat recovery heat exchanger including a housing having a working fluid inlet, a working fluid outlet, an exhaust inlet, and an exhaust outlet, an exhaust flow path extending through the housing between the exhaust inlet and the exhaust outlet, and a working fluid flow path extending through the housing between the working fluid inlet and the working fluid outlet and having a first portion and a second portion. A flow of working fluid along the first portion of the working fluid flow path can be substantially counter to a flow of exhaust along the exhaust flow path, and the flow of working fluid along the second portion of the working fluid flow path can be substantially parallel to the flow of exhaust along the exhaust flow path.
