The structural characteristics of parallel tube aluminum flat tube profiles for automotive heat exchangers were analyzed. A new die structure is present, and a semi integral core structure is proposed. The selection of new die structure parameters is introduced, which included the selection of extrusion machine capacity, the layout of hollow holes, the structure of the cores, the size of guiding holes, the structure of the welding chamber and the bearing of cores and the die hole etc. The practice shows that the new structure can effectively prevent the premature fracture of the cores and greatly improve the service life of the die.
