    摘要： The invention relates to an extruded tube for a heat exchanger, comprising two at least approximately parallel outer side walls (1, 2) that extend in a longitudinal direction (z) and a transverse direction (y) of the extruded tube and that are connected by means of two outer narrow sides (3, 4) in a vertical direction (x) of the extruded tube, wherein at least one continuous web (5) extends between the side walls (1, 2) in the longitudinal direction (z) and in the vertical direction (x) and separates at least two ducts (6) of the extruded tube, and wherein at least one of the outer side walls (1, 2) has embossings (7) that serve to form both bulged portions (7), that project into the ducts (6), of the side walls (1, 2) and also bulged portions (7), that extend substantially in the transverse direction (y), of the web (5), wherein the bulged portions (7) of the at least one web (5) have a controlled orientation with respect to the transverse direction (y).

    摘要： The invention relates to a heat exchanger (10, 20), particularly an exhaust gas heat exchanger, for transferring heat in two stages between a first fluid (1) and a second (2) and third fluid (3) that have different temperatures. Said heat exchanger (10, 20) comprises a block (5, 55) for separately conducting the first (1) as well as the second (2) and third fluid (3) in a heat transferring manner. The block (5, 55) encompasses a number of ducts (7A, 7B, 47) through which the first fluid (1) can flow, a first chamber (9A, 9B) of a high-temperature part (11, 51), through which the second fluid (2) can flow and which accommodates the ducts (7A, 7B, 47), a second chamber (9A, 9B) of a low-temperature part (13, 53), through which the third fluid (3) flows and which accommodates the ducts (7A, 7B, 47), and a housing (15, 45, 45A, 45B) in which the first (9A, 49A) and second chamber (9B, 49B) as well as the ducts (7A, 7B, 47) are arranged. The aim of the invention is to produce such a two-stage heat exchanger at a low cost and keep the leakage between the high-temperature part (11, 51) and the low-temperature part (13, 53) low. Said aim is achieved by separating the first chamber (9A, 49A) and the second chamber (9B, 49B) from one another by means of a separation area (17, 57) that is mounted in a groove (65).

    摘要翻译： 本发明涉及用于在具有不同温度的第一流体（1）和第二流体（2）和第三流体（3）之间以两级传递热量的热交换器（10,20），特别是排气热交换器。 所述热交换器（10,20）包括用于以热传递方式分开地导引第一（1）以及第二（2）和第三流体（3）的块（5,55）。 块体（5,55）包括多个第一流体（1）能够流过的管道（7A，7B，47），高温部件（11,51）的第一腔室（9A，9B） 低温部分（13,53）的第二腔室（9A，9B），第二流体（2）能够流过第一腔室并容纳管道（7A，7B，47），第三流体 ）流动并且容纳管道（7A，7B，47）和壳体（15,45,45A，45B），其中第一腔室（9A，49A）和第二腔室（9B，49B）以及管道 7A，7B，47）。 本发明的目的是以低成本生产这种两级热交换器并且将高温部分（11,51）和低温部分（13,53）之间的泄漏保持在低位。 所述目的通过借助于安装在凹槽（65）中的分离区域（17,57）将第一腔室（9A，49A）和第二腔室（9B，49B）彼此分开来实现。
