Claims

[Scope of utility model registration request]

A radiator in which fins made of corrugated thin metal plates are interposed between a large number of flat tubes parallel to the air flow direction that communicate a pair of tanks with each other at intervals. The fin is characterized in that both ends of the portion that contacts the tube are sharply bent to form a flat intermediate portion between the bent ends, and the front edge of the fin is flush with the upstream edge of the airflow of the tube. Corrugated fin structure of the radiator.
