摘要： An exhaust gas heat exchanger includes exhaust gas tubes (110) through which exhaust gas generated by a combustion flows and cooling water tubes (120) through which cooling water for cooling exhaust gas flows. Plural segments (112) of offset fins (111) are disposed within each exhaust gas tube to be arranged staggeringly in a tube longitudinal direction. The cooling water tubes communicate with each other through cooling water communication passages (120b) disposed on both end sides of each exhaust gas tube in the tube longitudinal direction at diagonal positions when being viewed from a minor-diameter direction of each exhaust gas tube. The segments are tilted relative to the tube longitudinal direction toward a side opposite to a diagonal line (L1) connecting the cooling water communication passages. Thus, a cross angle between the tilt direction of the segments and a main flow of the exhaust gas becomes smaller, and a pressure loss in the exhaust gas tubes is reduced.

摘要： A heat exchanger includes fins (111) having a plurality of sets of two louvres (111c) substantially triangular in shape which are formed in such a manner that the distance from a flat plate portion (111a) increases progressively downstream in the gas flow direction. The two louvres (111c) of each set are arranged inwardly slanted along the gas flow direction, so that a vertical swirl is generated to draw the gas flow between the louvres (111c). The gas flowing in the vicinity of the flat plate portion (111a) and the gas flowing in the vicinity of a vertical plate portion (111b) are thus accelerated. As a result, the heat conductivity of the gas and the fins (111) is improved and the particulate matter attached on the surface of the fins (111) can be blown off, thereby preventing the clogging of the fins (111).

摘要： The internal combustion engine exhaust gas heat exchanger involves an exhaust gas recirculation system cooler with a core area (130) of several small pipes (120) through which cooling water flows. It has several ribs (111) between adjacent pipes through which exhaust gas flows. The pipes through lamination of several lamination plates are formed in a lamination direction. The core area is formed in a core housing (143), with a free space being formed between area and housing. Condensed water produced by the exhaust gas in a through passage (110) in the core housing flows through the free space downwards.

摘要： The exhaust gas heat exchanger (100) has a tube (101) made of two U-shaped plates which are fitted together facing each other. A level difference is formed on each of the portions of the second plate on which the first plate is fitted, in which the level difference is equal in height to the thickness of the first plate and protrudes inwardly of the tube. The second plate is disposed inside the first plate. An inner fin is disposed within the tube to promote heat exchange between the exhaust gas and coolant.
