摘要： A finned tube assembly for an air cooled condenser and method for forming the same. The finned tube assembly comprises a flow conduit in the form of a bare steel tube and at least one set of fins bonded directly to the tube. In one embodiment, the tube has a non-circular cross section and the fins have a serpentine configuration. An oil based carrier and flux mixture is used in one embodiment to braze the fins onto the bare tubes, A braze filler metal may he introduced proximate to the bonding site by several different delivery mechanism. The braze filler metal may be aluminum or aluminum silicon. The finned tubes assemblies are combined in tube bundles and assembled to form an air cooled condenser which may be used in power generation, station, and other applications.
