摘要： PURPOSE:To improve the standing density of a pipe and to reduce the cost in brazing by forming a brazing filler metal layer by depositing the brazing filler metal to a plate stock and heating the brazing filler metal layer in the state of inserting the material to be joined by piercing a through hole on the plate stock. CONSTITUTION:The end plate 2 provided with a recessed part at the upper face side is manufactured by forming a rise edge 10 on the outer peripheral edge and a brazing filler metal is melted by its heating inside the recessed part to deposit a brazing filler metal layer 11 covering the upper face of the end plate 2. The through hole 12 integrally penetrating the brazing filler metal layer 11 and end plate 2 is pierced on the end plate 2 and a pipe 4... is inserted therein. The brazing filler metal layer 11 is melted by heating it by heating this assembly body in a vacuum heating furnace and the brazing of each pipe 4 onto the end plate 2 is executed in a lump. In this case, the brazing filler metal layer 11 having existed at the upper face side edge part of each through hole 12 in the end plate 2 is melted and flowed into the gap between each pipe 4 and the inner peripheral face of the through hole 12 and brazed joining in the state of filling up this gap is executed. The standing density of the pipe is thus increased and the brazing cost can be reduced.
