摘要： A method of manufacturing an outside plate used for a heat exchanger header tank configured such that an outside plate having an outwardly bulging portion, an inside plate, and an intermediate plate are brazed together in layers. A thick portion is formed on an outside-plate forming metal plate at a center portion with respect to the width direction thereof. Subsequently, a press work is performed on the outside-plate forming metal plate so as to form the outwardly bulging portion by making use of the thick portion. A connection portion having a curvature radius of 1 mm or less is formed between an inner wall surface of the outwardly bulging portion and each of surfaces of the outside plate located on the opposite sides of the outwardly bulging portion. This method enables manufacture of an outside plate which reduces the weight while securing sufficient withstanding pressure.

摘要： A heat exchanger includes two header tanks and a plurality of heat exchange tubes. The header tanks each include an outside plate, an inside plate, and an intermediate plate. The outside plate has an outwardly bulging portion(s). The inside plate has a plurality of tube insertion holes. The intermediate plate has communication holes for allowing communication of the tube insertion holes with the outwardly bulging portion of the header tank. A pair of inclined portions inclined in a fanning-out fashion toward the inside plate are formed at inside-plate-side edge portions of opposite wall surfaces of each communication hole which extend in the hole-length direction. Projecting portions of the inside plate are formed by bending, toward the intermediate plate, portions of the inside plate located at opposite edges of each tube insertion hole which extend in the hole-length direction. The projecting portions are closely brazed to the corresponding inclined portions.
