| 摘要 |
The invention relates to a heat exchanger for a first and a second medium flow, comprising flat tubes (12) which have internal fins (15, 15a, 15b) formed from zigzag-shaped sheet metal plate (16, 16a, 16b). The tubes have a thermally conductive connection to at least one duct for the one medium flow. Each fin (15, 15a, 15b) is fixed only to the one longitudinal side (17, 18) of each tube (12). Furthermore, there is a gap (19) between the fins fixed to the one longitudinal side (17, 18) and the opposite longitudinal side (17, 18) of the tube (12). |
