| 摘要 |
The invention relates to a heat exchanger (12) comprising plate pairs (29) stacked one above the other, wherein a first flow chamber is formed between the two plates (30, 31) of a plate pair (29) by conducting a first fluid therethrough, a second flow chamber (21) for conducting a second fluid therethrough, wherein the second flow chamber (21) is formed between two adjacent plate pairs (29), an inlet opening (32) for introducing the first fluid, and an outlet opening (33) for discharging the first fluid. The aim of the invention is to make said heat exchanger (12) withstand high thermal and mechanical loads even over a long time period, such as 10 years. Said aim is achieved in that the plates (30, 31) have at least one expansion opening, in particular at least one expansion slit, for reducing stress in the plates (30, 31). |
