<P>PROBLEM TO BE SOLVED: To provide a brazing structure capable of preventing a clearance from being generated between a casing and a tank, even when a layered height of the cores varies by a manufacturing error and others, in the brazing structure for a layered type heat exchanger with no tube plate fit with the casing in an outer circumference of the core thereof and arranged with the tanks in both ends thereof. <P>SOLUTION: A stepped part 10 is formed in a height-directional one end of the tank 7 opening, an opening outer circumference of the tank 7 is engaged with inner faces of a body member 8 and a lid member 9, an inner face of an end wall 9b of the lid member 9 is brought into contact with an outer face of an erected wall 10a of a step part in the stepped part 10. A length of an overlapped portion 11 contacting with the end wall 9b of the lid member 9 and the erected wall 10a of the step part of the tank 7 is made changeable in response to a layered height of elements 4. <P>COPYRIGHT: (C)2012,JPO&INPIT |
