MULTIPLE TUBE BANK HEAT EXCHANGER ASSEMBLY AND FABRICATION METHOD

摘要

A multiple tube flattened heat exchange tube assembly includes a first flattened tube segment, a second flattened tube segment and a web member interconnecting the trailing edge of the first flattened tube segment and the leading edge of the second flattened tube segment. The web member may be provided with one or more retained water drainage openings. A multiple slab flattened tube heat exchanger is provided that includes a plurality of the multiple tube flattened heat exchange tube assemblies disposed in spaced parallel relationship. A method for fabricating a flattened tube finned heat exchanger having a first heat exchanger slab and a second heat exchanger slab is also disclosed.
