Abstract
A method of manufacturing radiators by joining a corrugated fin to a base plate, characterized by low costs and prevention of thermal deformation of the corrugated fin due to low-temperature soldering. A first soldering at the lower ends of the corrugated fin is conducted by a first soldering alloy in a recess heated by a heating plate in a mobile solder tank filled with the molten first soldering alloy. A second soldering alloy is heated by a heating plate on a base plate and the molten second soldering alloy is used to conduct a second soldering. When the corrugated fin is placed on the base plate, pressed and heated, the first and second solders are melted to join the corrugated fin to the base plate.
