である。However, since the ribs are hollow, the strength tends to be weak and deformation is likely to occur. For this reason,
A new problem arises in that the end portions of the liner are poorly adhered to each other, and thus the sealing performance is poor. In particular, when the end portions of the adjacent liners have insufficient strength, the sealing performance becomes worse. Therefore, it is an object of the present invention to provide a heat exchange element that is inexpensive to manufacture and has excellent sealing performance.

It is preferable to mix in by weight. Because 10%
If it is less than 50%, moldability and air permeability are deteriorated, and if it exceeds 50%, hygroscopicity is deteriorated. As the mixing ratio of the resin increases, the moldability tends to improve and the air permeability tends to decrease, and as the mixing ratio of the resin decreases, the moisture permeability tends to increase. Therefore, in order to satisfy the moldability, the air permeability and the moisture permeability, about 30% by weight is most preferable.

る。In particular, the transverse concave ribs 40 intersecting the second convex ribs 30 further improve the strength of the end portions of the liner 1, so that the sealing performance between the both end portions can be further improved.
Moreover, since the transverse recessed ribs 40 function as spacers that regulate the interval between the liners 1, the strength of the end portions can be further improved, and as a result, the above-mentioned sealing performance can be further improved. Since the above-mentioned end portions are combined with each other to complement each other in strength, even when either one of the second convex ribs 30 and the longitudinal groove ribs 20 is eliminated, the combined end portions are combined. Sufficient strength can be secured, and as a result, sufficient sealing performance can be achieved. Since the first ridge ribs 2, the second ridge ribs 30, and the vertical groove ribs 20 are integrally formed on the liner, the manufacturing cost can be reduced. Furthermore, since the convex spacers 3 and the transverse concave ribs 40 are also integrally formed with the liner 1, the manufacturing cost can be further reduced.

When a contact pressure is applied to one of the ends, the contact pressure is sequentially transmitted to the other liner 1 via the second convex rib 30 and the vertical concave rib 20. Since the contact pressure can be applied all at once in this way, the cost at the time of stacking and adhering can be reduced as compared with the conventional case in which the contact pressure is applied one by one and joining is performed. As a result, the manufacturing cost can be further reduced. As shown in FIG. 5, between the adhesive applying roller R2 which is in sliding contact with the adhesive supplying roller R1 immersed in the adhesive liquid in the adhesive tank B, and the roller R3 which faces the adhesive applying roller R2, a conveyor C is used. When a so-called roll coater method is adopted, in which an adhesive is applied to the protruding portions of the conveyed unit members U, the first convex ribs 2, the second convex ribs 20, and the vertical cut concave ribs 40 are used. The adhesive can be easily and evenly applied to the tops of the ridge spacers 3. As a result, it is possible to reliably bond the necessary parts and improve the sealing performance. Also liner 1
Even when a large number of sheets are stacked, unevenness in height does not occur, so that a large number of liners can be stacked at one time. Since the height of the transverse groove rib 40 is set to be the same as that of the other ribs such as the first rib 2 and the spacer, the structural strength of the heat exchange element can be further improved. Even if the height of the transverse concave ribs 40 is made lower than the height of other ribs such as the first convex ribs 2 or the spacers, the other ribs or the like provide sufficient structural strength of the heat exchange element. Is secured. Further, since no adhesive is applied to the top of the transverse recess rib 40, there is no problem even if the height is lower than other ribs. As shown in FIG. 3, between the upper and lower liners 1, the wall surface of the transverse concave rib 40 and the wall surface of the first convex rib 2 are in close contact with each other. The hermeticity can be further improved. In addition, even if the wall surface of the transverse groove rib 40 and the wall surface of the first rib rib 2 are brought close to each other with a predetermined gap, the sealing performance can be improved.
