HOEYTRYKKS VARMEVEKSLER MED ROERSATS BESTAAENDE AV FLATE OVALE ROER

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.
