| 摘要 |
The present invention relates to a heat exchanger (1) comprising a first flow passage (6) comprising a tubular element (2) comprising at least two tubular flow channels (4) separated by region (5) extending along a longitudinal Y-axis, for passage of a first medium, and a second flow passage (8) for passage of a second medium between tubular element and a heat transfer element (3). The tubular element comprises a first surface (A) comprising at least region and two bulging sections (7). The heat transfer element comprises a second surface (B) comprising at least region 5′ and two indentation, cavity or nest sections (17). The first surface and the second surface are adapted to contact each other and have a complementary shape such that the bulging sections of the first surface are in continuous contact with the indentation, cavity or nest sections of the second surface. |
