DOUBLE TYPE HEAT EXCHANGER

摘要

PROBLEM TO BE SOLVED: To prevent a drop in heat exchange capacity of a condenser core part by preventing the inclination of a radiator header tank. SOLUTION: The tip of a first protrusion part 24c used for fixing by caulking is brought into contact with a radiator header tank 35. As a result, the inclination of both the header tanks 24 and 35 (especially the radiator heater tank 35 larger in construction) can be prevented so that the completion of soldering can be blocked in a state where both the header tank 24 and 25 are kept in contact with each other over the relatively wider range. This can prevent any drop in the heat exchange capacity of a condenser core part.
