| 摘要 |
The invention relates to a combined air-water heat exchanger (1) having at least one flat absorber element (2) that is spirally rolled or wound, to which or through which a heating medium or brine can flow, and that is made of a first material having a first thermal expansion coefficient, and further having at least one flat spacer element (3) made of a second material having a second heat expansion coefficient that is different from the first, the element being located between the spaced adjacent layers or plies of the spiral absorber element (2) that do not contact each other, the flow of air or water through the heat exchanger (1) or the formation of ice being permanently ensured by residual free spaces (5) between the absorber element (2) and the spacer element (3). |
