Abstract
"TUBO APERFEIÇOADO PARA USO EM TROCADORES DE CALOR DE ALETAS EM SERPENTINA". Problemas devidos à queda de aletas na fabricação de trocadores de calor que têm tubos achatados (14) com aletas em serpentina intercaladas (16) são eliminados ao propiciar as faces exteriores (22), (24) do tubo (14) com saliências alongadas relativamente íngremes (36). As saliências (36) formam deformações (52) nas cristas das aletas (16) que travam as aletas (16) e os tubos (14) juntos durante o processo de soldagem a solda forte, impedindo deste modo tal queda.
