NEW DESIGNS OF BIMETALLIC FINNED TUBES FOR AIR-COOLED HEAT EXCHANGERS

摘要

Energy- and resource-conserving characteristics of heat-exchange tubes with wound-on helical aluminum fins, which are employed in air coolers, are presented. Designs of bimetallic finned tubes with intensified connective and contact heat exchange, enhanced thermal reliability, and high adaptability to fabrication are described. Characteristics are given for fabrication of the tubes.
