Abstract
An assembly (oil cooler unit), under the state where first and second plates ( ) prevent a heat exchange core ( ) from falling from a casing ( ), is provisionally assembled, and this oil cooler unit is dipped in a flux to apply the flux. A seal surface plate ( ) is then assembled to the second plate ( ) and is brazed by heat-brazing in an inert gas atmosphere. Since a flux residue on the seal surface plate ( ) can be drastically reduced in this manner after brazing is complete, the seal surface plate ( ) can secure predetermined surface texture even after brazing is complete while the number of process steps necessary for applying the flux is reduced.
