The present invention is an enhanced type of fin (14) for making an enhanced serrated finned tube (10) for use in heat exchange applications. The segments (24), which are formed on the fin (14) when the fin is serrated, are enhanced either prior to serration or after serration. The enhancement consists of impressing, cutting or otherwise providing indentations (74) into the segments (24), thus broadening the segments, increasing their surface area, and increasing their heat transfer capability. In addition, the base portion, i.e. the unserrated proximal portion of the fin, may also be enhanced to increase its surface area. |
