摘要： An object of the invention is to provide an EGR cooler which enhances a cooling performance by increasing a ratio of the volume of a core portion which performs a heat exchange and enhances a pressure resistance strength.
There is provided an EGR cooler having a core portion (1) in which a large number of flat tubes (4) through which exhaust gases pass are stacked one on another in an interior of a hollow cylindrical shell (7) to be joined to the shell (7) for heat exchange between the exhaust gases and a cooling fluid which flows around the tubes (4), a cylindrical inlet header (2) which is joined to an upstream side of the shell (7) in relation to a gas flow at one end thereof to thereby supply the exhaust gases into the core portion (1), and a cylindrical outlet header (3) which is joined to a downstream side of the core portion (1) in relation to the gas flow at one end thereof to thereby discharge the exhaust gases from the core portion (1), characterized in that the inlet header (2) and the outlet header (3) are joined to an outer surface of the shell (7), and the tubes (4)are joined to an inner surface of the shell (7) at those joint portions (13).
摘要翻译：本发明的目的在于提供一种EGR冷却器，其通过增加进行热交换的芯部的体积比率并提高耐压强度来提高冷却性能。提供了一种具有芯部（1）的EGR冷却器，其中排放气体通过的大量扁平管（4）彼此堆叠在中空圆柱形壳体（7）的内部中以与所述芯部壳体（7），其用于排气与围绕管（4）流动的冷却流体之间的热交换;圆柱形入口集管（2），其相对于气体流动连接到壳体（7）的上游侧从而将废气供应到芯部（1）中;以及圆柱形出口集管（3），其在芯部（1）的一端与气流相关的下游侧结合在一起从而从核心部分（1）排出废气，其特征在于入口集管（2）和出口集管（3）连接到壳体（7）的外表面，并且管（4）是在这些接合部分（13）处接合到壳体（7）的内表面。
