In the second forming roll B, fin retainers 15, 16 for holding the corrugated fins 10 for heat radiation are provided.
To form The forming of the fin retainers 15 and 16 is performed by punching the strip-shaped metal material M. For this reason, openings 17 and 18 composed of two window holes are formed between each of the stacked heat exchanger sheet elements 1B. Next, in the second forming roll, the fin retainers 15 and 16 are bent in the opposite direction to the partitioning bead 5 and cut along the outer shape, and the laminated heat exchanger sheet element 1B is laminated. It is difficult to get from the sheet forming belt 1A for the exchanger.

As described above, the laminated heat exchanger sheet 1 thus formed is assembled into a laminated heat exchanger element 9 as described above. Further, the fin retainer 15,
Since the protrusions 16 protrude from both ends, the corrugated fins 10 for heat radiation can be attached to this portion. next,
Referring to FIGS. 48 and 49, a description will be given of a temporary assembling method of the conventional laminated heat exchanger.

The laminated heat exchanger sheet 1 and the corrugated fins 10 for heat dissipation are manufactured by the respective forming devices 30 and 30 and assembled in the assembling device 41 as follows. First, a method for manufacturing the laminated heat exchanger sheet 1 will be described. The stacked heat exchanger sheet 1 is formed by the two forming apparatuses 30 (S in FIG. 49).
1). The stacked heat exchanger sheets 1 formed by the respective forming apparatuses 30 and 30 are discharged by belt conveyors 31 and 32.

At the downstream end of each of the belt conveyors 31 and 32, two belt conveyors 34 and 35 are arranged orthogonally, and the laminated heat exchanger sheet 1 is formed by two belt conveyors 31 and 32 It is transferred to the belt conveyors 34 and 35 of the table. After that, the laminated heat exchanger sheet 1
The belt is conveyed to the end by belt conveyors 34 and 35. During this transport step, the following processing is performed on the laminated heat exchanger sheet 1.

First, the stack type heat exchanger sheet 1 conveyed by one belt conveyor 35 is turned upside down by the reversing device 33 (S2 in FIG. 49). As a result, the fin retainers 15, 16 formed at both ends of the stacked heat exchanger sheet 1 project upward. Next, the laminated heat exchanger sheet 1 on each of the belt conveyors 34, 35
Is dried by the dryer 36 (S3 in FIG. 49).

Next, each belt conveyor 3 after the drying step
Powder flux is applied to the laminated heat exchanger sheets 1 on the sheets 4 and 35 by the flux applicator 37 (FIG. 49).
S4). FIGS. 50 and 51 show a powder flux application device. In this powder flux application device, work holders 44 are attached to belt conveyors 34 and 35 at predetermined intervals.

The work holder 44 holds the stacked heat exchanger sheet 1 vertically. A flux ejection nozzle 42 for ejecting powder flux supplied from a flux supply device (not shown) is disposed above the stacked heat exchanger sheet 1. Belt conveyor 34,
A reflection conveyor 43 for diffusing and convectively dispersing the powder flux ejected from the flux ejection nozzle 42 is arranged on the lower surface of the nozzle 35.

In this powder flux coating apparatus, the laminated heat exchanger sheet 1 carried out of the drying apparatus 36 is held vertically by the work holder 44, and then the laminated heat exchanger sheet 1 is moved to the belt conveyors 34, 35. As a result, the powder flux is ejected from the flux ejection nozzle 42 when the powder flux is conveyed immediately below the flux ejection nozzle 42, and the powder flux is applied to the sheet 1 for the laminated heat exchanger.

Since the powder flux ejected from the flux ejection nozzle 42 is diffused by the reflection conveyor 43, the powder flux can be uniformly applied to the laminated heat exchanger sheet 1.

On the other hand, the heat dissipating corrugated fins 10
After being formed by the fin forming machine 38, it is conveyed by the belt conveyor 39 and dried by the drier 40 (FIG. 49).
S5, S6). Thereafter, the laminated heat exchanger sheet 1 and the corrugated fins 10 for heat dissipation are carried into the assembling device 41.

In the assembling device 41, as shown in FIG.
Two belt conveyors 46 and 47 are disposed so as to be orthogonal to the two belt conveyors 34 and 35 at the ends of the two belt conveyors 34 and 35. Assembly device 41
First, the laminated heat exchanger sheet 1 in which the fin retainers 15 and 16 conveyed by the belt conveyor 35 protrude downward is transferred onto each of the belt conveyors 46 and 47, and the laminated heat exchanger sheet 1 is Then, the stacked heat exchanger sheets 1 in which the fin retainers 15 and 16 conveyed by the belt conveyor 34 project upward are superposed in the middle to form the stacked heat exchanger element 9 (S7 in FIG. 49).

Next, the fin retainers 15, 16 of the laminated heat exchanger element 9 on each of the belt conveyors 46, 47 will be described.
After the corrugated fins 10 are compressed and attached therebetween, the corrugated fins 10 are sequentially stacked on an assembling jig 45 arranged near the belt conveyor 47 to form a temporary assembly 48 (S8 in FIG. 49). Then, the laminated heat exchanger element 9 in the assembly jig 45 is
And the corrugated fins 10 have reached a predetermined number,
Replace with another assembling jig 45.

The temporary assembly 48 of the laminated heat exchanger formed by laminating a predetermined number of the laminated heat exchanger elements 9 and the corrugated fins 10 is carried into a heating furnace (not shown) and heated in the furnace. It is brazed integrally to form the laminated heat exchanger 13 shown in FIG. 44 (S9 in FIG. 49).

[0020]

In the above-described method of temporarily assembling the laminated heat exchanger, the corrugated fins 10 are attached between the fin retainers 15 and 16 projecting from both sides of the laminated heat exchanger element 9. One of the stacked heat exchanger sheets 1 forming the heat exchanger element 9 needs to be inverted during the conveyance (S2 in FIG. 49).

Therefore, in the conventional method of temporarily assembling a laminated heat exchanger, the processing steps from the molding machine 30 to the assembling device 41 are conveyed by belt conveyors 31, 32, 34, 35, 46, 47 and the like. When the reversing device 33 is interposed in the middle of the conveyance, the sheet 1 for the laminated heat exchanger is
Is produced, the production efficiency is reduced. Therefore, as shown in FIG. 48, the sheet 1 for a laminated heat exchanger was manufactured by two molding machines 30.

This manufacturing method is a desirable method for speeding up the manufacturing of the laminated heat exchanger sheet 1, but has a problem that the installation place becomes large. Further, in the conventional method of temporarily assembling a laminated heat exchanger, the processing steps from the molding machine 30 to the assembling device 41 are performed by the belt conveyors 31,
Since it is conveyed by 2, 34, 35, 46, 47, and the like, the following problems also occur in the drying step S3, the flux applying step S4, and the middle aligning step S7 of the laminated heat exchanger sheet 1.

First, in the drying step S3, it is not efficient to carry out the drying while transporting the laminated heat exchanger sheet 1 placed on the belt conveyors 34, 35.
The sheet 1 for a laminated heat exchanger is transferred to a belt conveyor 34, 35.
It is necessary to prepare a drying device that stands on the top and blows hot air on both sides of the laminated heat exchanger sheet 1, and there is a problem that the device becomes large.

Next, in the powder flux application step S4,
Since the powder flux spouted from the flux spouting nozzle 42 is diffused by the reflection conveyor 43 and applied to the laminated heat exchanger sheet 1, there is a problem that the apparatus becomes large and requires a large installation area. Was.

Further, since the powder flux ejected from the flux ejection nozzle 42 is diffused and applied to the laminated heat exchanger sheet 1, a huge flux for preventing the powder flux from scattering around. There is a problem that a protective cover is required, a large installation area is required, and a lot of man-hours are required for a manufacturing process and an installation process of the device. Furthermore, in the powder flux application step S4, the powder flux ejected from the flux ejection nozzle 42 is diffused and adheres to the surrounding belt conveyors 34 and 35, so that it is necessary to frequently perform maintenance and inspection work of the apparatus. However, there is a problem that a great deal of labor and time are required.

Further, since the powder flux spouted from the flux spouting nozzle 42 is diffused, there is a problem that the work of collecting the powder flux becomes complicated.
Further, a transfer device for transferring to the stacked heat exchanger sheet 1 conveyed by the belt conveyors 34 and 35 is required. Further, in the middle-stage aligning step S7, a large number of movements are performed to overlap the inverted stacked heat exchanger sheet 1 conveyed by the belt conveyor 35 on the stacked heat exchanger sheet 1 conveyed by the belt conveyor 34. Requires equipment.

Of the stacked heat exchanger sheets 1 which are simultaneously conveyed by the belt conveyor 35 arranged in parallel, the stacked heat exchanger sheet 1 on the belt conveyor whose front and back are reversed is stacked on the belt conveyor. Since the belt conveyor is superimposed on the heat exchanger sheet 1, two belt conveyors need to be arranged, and there is a problem of occupying a large area.

Further, the laminated heat exchanger sheet 1 conveyed simultaneously by the independent belt conveyors 46 and 47.
Since the sheets are overlapped with each other, there is a problem that if the conveying speed of any one of the stacked heat exchanger sheets 1 is shifted, predetermined assembly of the stacked heat exchanger sheet 1 may not be performed. . Furthermore, since the stacked heat exchanger sheets 1 are conveyed by the belt conveyors 31, 32, 34, and 35, the number of in-process sheets of the stacked heat exchanger sheets 1 increases, and the management of the manufacturing process becomes complicated. There was a problem.

Further, when the corrugated fin 10 is assembled, a complicated device is required to compress the corrugated fin 10 as shown in FIG. Further, after the corrugated fins 10 are compressed and attached between the fin retainers 15 and 16 of the laminated heat exchanger element 9, as shown in FIG. Therefore, an operation of inserting the jig into the assembling jig 45 is required.

The present invention has been made to solve such a conventional problem, and an object of the present invention is to provide a laminated heat exchange system capable of supplying a temporary assembly equivalent to a conventional assembly with a single forming apparatus. An object of the present invention is to provide a method of temporarily assembling a vessel.
