摘要： An exhaust gas heat recovery (EGHR) heat exchanger, for recovering waste heat from the hot exhaust gases of an internal combustion engine, having a housing and a cylindrical body disposed within the housing. The cylindrical body defines a central passageway and together with the housing defines an annular passageway for the flow of hot exhaust gases. A bypass means is disposed within the central passageway and adapted to selectively by-pass at least a portion of the exhaust gas from the central passageway to the annular passageway. The EGHR heat exchanger also includes at least one fluid tube extending along a tube axis and having at least one lobe extending the length of the tube thereby defining a lobed tube. The lobed tube is twisted about the tube axis forming a twisted lobed tube which is then coiled about the longitudinal axis within the annular exhaust gas passageway.
