<p><P>PROBLEM TO BE SOLVED: To securely perform brazing between side wall portions of an end plate and a head tank while omitting welding, etc., prior to brazing, even if a spring-back phenomenon occurs in the end plate. <P>SOLUTION: A peripheral wall portion of the head tank 5 is formed with first/second insertion holes A1, A2. First/second side wall portions 6b, 6c of the end plate 6 are formed with first/second insertion portions 6d, 6f, which are respectively inserted into the first/second insertion holes A1, A2 of the head tank 5. The first insertion portion 6d is formed to make a surface opposite to the second sidewall portion 6c contact an inner surface of the head tank 5. The second insertion portion 6f is formed, to make a surface opposite to the first sidewall portion 6b contact the inner surface of the head tank 5. The first/second insertion portions 6d, 6f are brazed to the inner surface of the head tank 5. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
