The partly profiled plates are sealed along all edges by soldering, welding or similar, and have distance pieces in the feed regions. Such pieces, on both the prim. and sec. sides, have spreading and collecting components for one medium, and through passages for the other. - The distance pieces have neutral zones (8a) between the channels (2a, 2b), the spreading components (6a), and the through passages (7a). The neutral zones have all-round sealed distance maintaining zones, and with outlet holes (9a) separate from both the prim. and sec. medium neutral zones for free outlet for any leaking medium. |
