Abstract

A heat exchanger tube is constituted by a flat tube bodyshaped like a plurality of cylindrical tubes arranged mutually proximally in a plane and connected together at mutually proximate portions of the tubes as communicating portions. Cylindrical portionscorresponding to the cylindrical tubes of the flat tube bodyhave inner peripheries formed with swirling-flow-forming protrusionsdirected along spiral trajectories coaxial with central axes O of the cylindrical portionsso that the respective cylindrical portionsmay have individual swirling flows of the exhaust gas
