脂による断熱層である〕。 Conventionally, in this type of pipe-on-sheet cooler, as shown in FIG. 8, a cooling pipe 4 constituting a refrigerant circuit has been adhered to an inner box plate 2 forming an inner box using an epoxy adhesive 3 or the like. However, in the case of such an adhesive method, the adhesive 3 is naturally present between the inner box plate 2 and the cooling pipe 4, which becomes a factor that inhibits heat conduction. Furthermore, the contact area between the inner box plate 2 and the cooling pipe 4 is also limited,
In order to improve heat conduction, the number of turns in the cooling pipe 4 is increased, which means that a long cooling pipe 4 is required for the inner box plate 2 of a certain area, which makes the cooling pipe 4 expensive. is a heat insulating layer made of foamed urethane resin].

There were drawbacks such as the time required for the adhesive to harden.

以下図に基づいて本発明に係るパイプオンシー
ト（正確にはプレート）構造の熱交換器（代表例
として冷却器を挙げる）の製造方法を説明する。 DESCRIPTION OF THE PREFERRED EMBODIMENTS A method of manufacturing a heat exchanger (a cooler is taken as a typical example) having a pipe-on-sheet (plate) structure according to the present invention will be described below with reference to the drawings.

されている。 First, the structure of the cooler to be manufactured is shown in Fig. 2, which includes an inner box plate 2 and its heat insulating layer (a foamed urethane resin layer formed by injection of a foaming stock solution) 7.
A copper pipe 4 having a substantially half-moon cross section with a flat part 4' in contact with the side surface, and an inner box plate 2 that connects this copper pipe
It is composed of an aluminum foil sheet 5 with an adhesive attached to the top.

効率が悪い。 As described above, the aluminum foil sheet 5, which has been formed into a corrugated shape in advance, is extended by the pressure applied by the press punch 8, which has elasticity due to the provision of an elongation allowance, and the cooling pipe 4 and the inner box plate 2 are stretched. It is possible to secure a large heat conduction area by adhering in a straight shape, and it is possible to obtain a cooler with a pipe-on-sheet structure that has good heat exchange efficiency. In particular, since there is no need to provide a groove for accommodating the cooling pipe 4 in the inner box plate 2 or to match the cooling pipe 4 to the corrugated shape of the aluminum foil sheet 5, the assembly work is significantly simplified. Moreover, the air layer 6 shown in FIG. 2 is also very small and there is no fear of it breaking, making it extremely effective in manufacturing. If the aluminum foil sheet is not formed into a corrugated shape in advance, it is expected that the aluminum foil sheet will become stretched due to the pressure applied by the press punch 8 as shown in Fig. 5, and the air space 6 will become large. has poor heat exchange efficiency.
