| 摘要 |
The invention concerns a heat exchanger (1) for two fluids flowing in crosscurrent flows, comprising crosswise layers of structured, in particular undulated, metal sheets (2, 20) which form a plurality of flow channels (3, 30) and between which smooth metal sheets (8, 80) are arranged. The edge region (6, 7) of the structured metal sheet (2, 20), in each case extending in the flow direction of the one or other fluid, is surrounded on both sides by strips (4, 5) which are integral components of the smooth metal sheet (8, 80). |
