  • Tube for use in serpentine fin heat exchangers
    Patent number: 6397939
    Abstract: Problems due to fin fall-out in the manufacture of heat exchangers having flattened tubes (14) with interposed serpentine fins (16) are eliminated by providing the exterior sides (22), (24) of the tube (14) with elongated, relatively sharp ridges (36). The ridges (36) form deformations (52) in the crests of the fins (16) which lock the fins (16) and the tubes (14) together during the brazing process, thereby preventing such fall-out.
