FIG. 1 is an explanatory diagram schematically showing an example of a manufacturing method for manufacturing a honeycomb type cylindrical heat exchanger. 3 in the figure is a coater that applies an adhesive to a sheet of kraft paper 4, and the adhesive used in this case is polyester. The adhesive application patterns in this example are patterns A and B in FIG. For pattern B 6, the adhesive is applied in staggered positions so that it forms a honeycomb shape when spread out after adhesion. 5 and 6 in the diagram
is the area (pattern) where adhesive is applied.
As the coater 3 rotates, both patterns A and B in FIG. 2 are alternately printed on the craft paper 4. The printed kraft paper 4 is continuously passed through a drying oven 7. After drying, both patterns A and B shown in FIG. 2 are cut out using a cutting machine 8 and laminated one after another in a laminating machine 9. Next, as shown in Fig. 3A, the required number of laminates 11 are sandwiched between galvanized iron plates or aluminum plates 12 and 13 at the top and bottom, pressure is applied from the top and bottom using a press 10, and the laminate is placed in a heating furnace at 150°C. After being left in the container for about 15 minutes, it is naturally cooled to form a single block 26. This is expanded with one end as an axis as shown in Fig. 3 (b) and (c), and the aluminum plates 12, 13
By fixing them together, a cylindrical heat exchanger as shown in FIG. 4 is completed. In the figure, 14 is a rubber sheet spread around the outer periphery of the cylinder, and 15 is a hole into which the rotating shaft of the cylindrical heat exchanger is inserted.

This will be explained with figures. As shown in FIGS. 6A and 6B, flat sheets 16 and 17 each having a cut portion 18 and bonded with adhesive are stacked alternately around the shaft 15 at the end in sets of eight. By thermocompression bonding and unfolding, a cylindrical heat exchanger as shown in FIG. 7 is formed. The distance between the adhesive patterns on the flat sheets 16 and 17 is wider closer to the axis 15, but this is to equalize the opening areas of the air passages on the inner and outer circumferential sides during deployment. . Cut part 18
correspond to the hollow portions 19 and 20 in FIG. At the end of the cylindrical heat exchanger, shielding portions 21 and opening portions 22 are formed alternately. As a result, a ventilation circuit as shown in FIG. 8 can be formed. In addition, the planar sheets 16 and 17 contain or have a moisture absorbent applied to the cylindrical heat exchanger at the paper stage or after being expanded to form a cylindrical heat exchanger. In the embodiments described above, the cylindrical heat exchanger is constituted by the single block 26, but as shown in FIG. It is also possible to configure one cylindrical heat exchanger.
