PROBLEM TO BE SOLVED: To provide a tube for a heat exchanger capable of preventing deterioration of pressure resistance by preventing deviation when bending and joining a tube body. SOLUTION: The tube 1 for the heat exchanger is a tube bent and joined to form coolant passages 3 passing a coolant through an interior, and a partition wall 4 partitioning the coolant passages 3. It is characterized by that the partition wall 4 is composed of a protruding part 11 and a recessed part 12 engaging with each other when the tube body 2 is bent. COPYRIGHT: (C)2008,JPO&INPIT |
