Heat exchanger for radiator, has space formed at intermediate section between tank plate and core plate upon contact between bent end and side wall

摘要

A tank plate (2) and a core plate (3) have bent ends (2a,3a) that are parallel to side walls (23,32), respectively. The bent end of the tank plate contacts the side wall of the core plate while forming a step difference, and vice versa. A space is formed at an intermediate section between the tank plate and core plate upon contact between bent end and side wall.
