Abstract: A method of manufacturing an aluminum heat exchanger comprising the steps of: forming inclined surfaces on a support plate including an aluminum core clad with a brazing material layer at least on its top surface, said inclined surfaces sloping downwardly toward an aperture in the support surface; inserting a water pipe having an outer wall made of aluminum into said aperture with said core held in contact with said water pipe; assembling said support plate and said water pipe so that, when heated, said brazing material layer is melted, and flows down toward and collects around said aperture wherein said water pipe contacts said support plate; and heating said support plate and said water pipe to melt the brazing material layer, whereby the parts to be joined can be brazed together.
