（イ）産業上の利用分野
本発明は熱交換器の製造方法に関し、特に、例えば電気

交換器の製造方法に関するものである。Detailed Description of the Invention (a) Field of Industrial Application The present invention relates to a method for manufacturing a heat exchanger, and in particular to the insulation of a metal plate or synthetic resin molded product forming an inner box of, for example, an electric refrigerator or freezer. The present invention relates to a method for manufacturing a so-called pipe-on-sheet structure cooler in which a refrigerant circuit is directly bonded to a side wall surface, or a heat exchanger such as a condenser.

化しなければならず作業環境の悪化、作業時間の長時間
化（接着剤の同化時間を要す）等という欠点があった。In addition, the contact area between the inner box plate (2) and the cooling pipe (4) is limited, and in order to improve heat conduction, the number of turns of the cooling pipe (4) must be increased, that is, the inner box plate has a constant area. In contrast to (2), it requires a long cooling pipe (4) and is expensive [note that (7) is a heat insulating layer made of foamed urethane resin. Furthermore, in the manufacturing process, after applying the molten adhesive to the inner box plate (2) or the cooling pipe (4), the adhesive must be solidified during the application of pressure under body weight, which worsens the working environment. However, there were disadvantages such as a long working time (requires time for assimilation of the adhesive).

There was also a problem that the heat exchange efficiency with the inner box plate (2) deteriorated.

2) The cooling pipe (4) and the aluminum foil sheet (5) are stacked one on top of the other in order and pressed from above with a press punch (8) having elasticity such as a rubber mold. Corrugated aluminum foil sheet (5)
has a shape with an allowance for expansion, and is deformed and expanded by the pressure applied by the press punch (8), and is bonded along the cooling pipe (4) and the inner box plate (2).
As a result, a large heat conduction area can be secured, and a cooler with a pipe-on-sheet structure with good heat exchange efficiency can be obtained. In particular, there is no need to provide a groove to accommodate the cooling pipe (4) in the inner box plate (2) or to match the cooling pipe (4) to the corrugation of the aluminum foil sheet (5), which greatly simplifies the assembly work. . In addition, the air layer shown in FIG. 2 is also very small, and there is no fear that it will break, making it extremely effective in manufacturing.

達成することが可能となるものである。(G) Effects of the Invention According to the present invention, when fixing a heat exchange pipe formed in a meandering shape to a metal plate or a synthetic resin plate, the aluminum foil sheet can be heated by simply stacking and pressing corrugated aluminum foil sheets. It can be bonded along an exchange pipe and a metal plate or a synthetic resin plate, and a heat exchanger with good heat exchange efficiency can be constructed extremely easily. Further, the present invention is suitable for automation, and there is no need to match the heat exchange pipe to the corrugated shape of the aluminum foil sheet, so it is highly suitable for mass production and can reduce the product price. In particular, in constructing the corrugated aluminum foil sheet in the present invention, since the adhesive coated sheet is formed into a corrugated shape, the adhesive can be applied in a flat plate state, and the adhesive can be evenly applied to the aluminum foil sheet, thereby making it possible to apply heat to the aluminum foil sheet. It is also possible to securely fix the replacement pipe to the metal plate or synthetic resin plate.
