ABSTRACT:
A heat exchanger of this invention used as a radiator for an automotive vehicle has a core plate having a holding groove around its periphery for receiving a seal member as well as a flange of a tank member, wherein a concave-convex portion is formed in the outer surface of the outer or inner side wall forming the holding groove. According to this structure, an excess molten solder is gathered toward the concave-convex portion when the core plate is heated for soldering in a heat furnace. This prevents the excess solder from making a drop-shaped mass which has an adverse influence on a seal efficiency of the seal member.
