PROBLEM TO BE SOLVED: To prevent the lifetime of a run out of a duplex heat exchanger from becoming short, while preventing a rise of manufacturing cost of the run out. SOLUTION: A run out 5 has one end thereof brazed to a condenser tank portion 4 and the other end thereof brazed to a connecting block 6, which, in turn, is brazed to a radiator tank portion 3. Therey, the run out 5 can have a both-end supported structure. Accordingly, the bending moment applied to the run out 5 can be decreased so that cracks and the like which may be caused by vehicle vibrations can be minimized thus preventing the lifetime of the run out 5 from becoming short. |
