| 摘要 |
The object of the invention is a heat exchanger (1) for transferring heat between gas flows directed principally counter current, the walls of the heat exchanger (1) separating the flows from each other being flexible film (3), through which the heat transfer takes place. The heat exchange elements (2) are attached to each other by welding so that no rigid side walls are required. In this case, the heat exchanger (1) can be folded especially for packaging, transport and installation.
