摘要: In a tube for a heat exchanger, a plurality of passages is defined. The passages are arranged in rows parallel to a major axis of the tube cross-section and staggered. When the tube is extruded, an extrusion material can flow around dies for forming passages and easily merge between the dies. Since walls between adjacent passages can be easily formed, formability of the tube is improved.
