Manufacture of heat exchanger

Abstract

Abstract PURPOSE:To easily and surely manufacture the heat exchanger having good efficiency by superposing a plate, zigzag heat exchange pipe, and corrugated aluminum foil coated with an adhesive agent onto a press bed successively from below and pressing the same by an elastic press machine from above. CONSTITUTION:The inside box plate 2, cooling pipes 4, and the aluminum foil sheet 5 of a refrigerator made of a metal or synthetic resin are successively superposed on the press bed 9 from below. The above-mentioned cooling pipe 4 which is formed zigzag and is formed to a flat part 4' on the inside box plate 2 side is used. The above-mentioned aluminum foil sheet 5 which is coated with the adhesive agent and is formed to a corrugated shape is used. These materials are then pressed from above by a press punch 8 such as a rubber punch having elasticity. The aluminum foil sheet 5 is deformed and elongated with the corrugated shape thereof as a margin for elongation by this pressurization and is adhered to the cooling pipe 4 and the plate 2 along the same so that the flat part 4' is tightly adhered to the plate 2 with substantially no remaining air layers 6. A heat insulating layer 7 is then formed at the upper part of the aluminum foil sheet 5. The cooler having the good heat exchange efficiency is thus obtd.
