HEAT EXCHANGER FOR GASES, IN PARTICULAR FOR EXHAUST GASES FROM AN ENGINE, AND METHOD FOR MANUFACTURING SAME

An exchanger includes: a heat exchanger block (B) with: a first circuit for the circulation of gases and a second circuit for the circulation of a coolant fluid that are arranged to effect a heat exchange between the gases and the coolant fluid, a part (P) with a through-hole (h) arranged so that the gases or the coolant fluid flow therethrough, and a tubular pipe (T) with a projection (F) that extends radially outwards from one end (Ta) thereof and that is joined to a region that surrounds the through-hole (h). The method includes the manufacture of the heat exchanger according to the presentinvention. 本发明涉及一种用于气体的热交换器，特别用于来自发动机的排气，且涉及制造该热交换器的方法该交换器包括：-热交换器块(B)，具有：用于气体流通的第一回路和用于冷却剂流体流通的第二回路，其布置成实现气体和冷却剂流体之间的热交换，具有通孔(h)的部件(P)，其布置成使得气体或冷却剂流体从中流过，和-具有突出部(F)的筒状管(T)，突出部(F)从其一个端部(Ta)径向向外延伸并且连接到围绕通孔(h)的区域。所述方法包括制造根据本发明的热交换器。
