Abstract:
A brazing method includes shaping a clad sheet to form a hollow structure. A tube is then partially inserted into a through hole in the hollow structure, thereby forming an assembled aluminum structure. The exterior surface of the hollow structure adjacent the through hole is composed of an Al—Si alloy that serves as a first filler material. The interior surface of the hollow structure adjacent the through hole is composed of an Al—Si alloy containing at least one of Cu and Zn and having a solidus temperature of 570° C. or less that serves as a second filler material. The assembled aluminum structure is brazed by heating it in an inert-gas atmosphere such that fillets joining the hollow structure to the tube along the through hole are formed first on the interior surface of the hollow structure and then on the exterior surface of the hollow structure.

Claim (Index 14):
The method according to  claim 10 , wherein prior to performing the brazing process, the hollow structure is etched using an acid or an alkali.
