Disclosed is a heat exchanger, especially an exhaust gas heat exchanger, comprising a housing (101, 201, 301, 401, 501, 601, 702, 801, 901, 1101, 1401, 1501, 1901, 2001, 2101, 2201) which can be penetrated by at least one first medium (M1) and at least one second medium (M2), and at least one sealing element (213, 607, 707, 906, 1006, 1011, 1411, 1506, 2205). At least one flow means (217, 1507, 1507a, 1508, 1904, 2005, 2105, 2206, 2206a, 2206b), around which the second medium flows, is provided inside the housing, said flow means improving heat transfer from the first medium to the second medium. |
