| 摘要 |
The present invention relates to mechanically assembled high internal pressure flat oval tube heat exchangers, where fin plates are provided with a special wavy configuration forming pattern of a zig-zag, sinuous or semicircular form or a combination of these forms. Preferably the waves are running in parallel in relation to the longest axis of the flat oval tube cross sections in a direction vertical to the tubes' longitudinal axis, thus increasing substantially the deformation pressure yield of the tubes. |
