Abstract: An aluminum alloy including magnesium can be joined by brazing even when flux made of potassium fluoaluminates is employed. The aluminum alloy including magnesium is heated in a vacuum, so that magnesium in the aluminum alloy evaporates from the surface of the aluminum alloy. The weight ratio of magnesium at the surface of the aluminum alloy can be reduced to less than 0.5 as a result of the heating step. The aluminum alloy treated by this operation is, thereafter covered with brazing material and clad with flux. After that, the aluminum alloy is heated in a furnace in order to melt the brazing material.

Abstract: A cooling device has a radiator plate and a corrugated fin for cooling an electrical component. In a manufacturing process of the cooling device, a symmetrically constructed tool section presses the radiator plate and the fin against an anvil. The radiator plate has an attaching portion where an electrical component is attached. Knurled surface for preventing a slide is formed on the tool section only at a surrounding area to prevent a deformation of the attaching portion. The tool section and the radiator plate vibrate ultrasonically in a longitudinal direction of corrugations of the fin to prevent a crack on the fin.

Abstract: A tube is formed by brazing first and second plates, and is connected to a pipe through a connection block being brazed to a contacting surface of the first plate. A brazing material is clad on an inner surface of the first plate opposite to the contacting surface, and a hole penetrating through the first plate is formed in the first plate at a position corresponding to the connection block. Thus, during brazing, the brazing material clad on the inner surface of the first plate is supplied to the contacting surface through the hole by capillary phenomenon, so that the connection block is brazed to the first plate. As a result, an apparatus formed by brazing plural metal members, such as the tube of an oil cooler, is produced in low cost.
