ら積層することにより製造していた。The plate-fin type heat exchange element has a large heat transfer area per unit volume and is widely used as a relatively small and highly efficient heat exchange element. It can be divided into three types: flow type, counter flow type and orthogonal (oblique) flow type. Counterflow type and crossflow type are often used for air conditioners, and the basic structure is described in JP-B-47-19990, and heat exchange is performed as shown in the perspective view of FIG. A plate that separates two fluids that should be
(101) corrugated fins forming a double-row parallel flow path (102)
It is said that it is laminated with sandwiching. In the heat exchange element (100) for air conditioning, the plate (101) is made of a processed paper based on a paper material having both heat conductivity and moisture permeability,
The fins (102) are also obtained by processing a paper material similar to the plate (101) into a corrugated shape. The heat exchange element (100)
Is the plate (101) and fin (10) shown in the perspective view of FIG.
It is obtained by forming a unit member (103) composed of 2) in advance and laminating a plurality of the unit members so that the parallel flow paths are orthogonal to each other at every stage. Specifically, the unit member (1
03) is a corrugated machine, and the fins (102) formed in a corrugated shape are made into plates (101) using an adhesive such as vinyl acetate.
The heat exchange element (100) was manufactured by laminating the fins (104) of the unit member (103) while applying an adhesive such as vinyl acetate.

とにより製造していた。After that, in order to improve the performance and productivity of the heat exchange element, a heat exchange element (200) as shown in the perspective view of FIG. 6 was invented (filed on January 29, 1986 by the same applicant as “Heat Exchange”). Exchanger "(Japanese Patent Application No. 61-017221). This is because the member corresponding to the fin is made of synthetic resin, and the fin (202) of arbitrary height and pitch is integrally formed on the plate (201) with high precision and the unit as shown in the perspective view of FIG. It was manufactured by forming a member (203) and laminating it while applying an adhesive to the end face (hereinafter referred to as the top) (204) opposite to the plate side.
ところが，フインの頂上部に粘着性を有する接着剤を塗

熱交換素子の性能および生産性が劣るという問題点があ
つた。However, it is difficult to precisely stack the unit members with adhesive adhesive applied to the top of the fin.
There is a problem that the performance and productivity of the heat exchange element are poor.
従つて単位部材の積層工程においては粘着性を示さず，
積層が完了し各単位部材を位置決めした後，一挙に単位
部材群を接合できる方法が要望されている。Therefore, it does not show tackiness in the lamination process of unit members,
There is a demand for a method in which unit members can be joined at once after stacking is completed and each unit member is positioned.

である。A method of manufacturing a heat exchange element according to the present invention includes a step of forming synthetic resin fins forming parallel flow paths through which a heat medium flows in parallel on one surface of a flat plate to form a unit member, and the fin side of the plate. A step of applying a hot melt resin having a melting temperature lower than that of the synthetic resin to the end surface opposite to the above, and combining the end surface of the unit member coated with the hot melt resin and the other surface of the next stage plate with a plurality of the unit members. The step of laminating and the step of joining the unit member groups by heating the laminated unit member groups to a temperature higher than the melting temperature of the hot melt resin and lower than the melting temperature of the synthetic resin are performed.

を接合できるので生産性が向上する。The hot melt resin of the present invention is
That is, since it does not exhibit tackiness at room temperature, it can be laminated accurately and quickly. Further, since the laminated unit member groups are heated to melt the hot melt resin and the unit members can be joined at once, the productivity is improved.

が製造される。As the flat plate in the present invention, a plastic sheet or a thin metal plate can be used in addition to various paper materials and processed paper. In the former case, not only sensible heat (temperature) but also latent heat (humidity) is exchanged, so that a total heat exchange element is manufactured. In the latter case, a heat exchange element for exchanging sensible heat is manufactured.

の接着性に優れる。As the synthetic resin forming the fin, a thermoplastic resin having a polar group in its side chain or a hot melt resin having a low melt viscosity is used. In the case of the former, the adhesion to the plate is excellent due to the presence of polar groups, and in the case of the latter, it penetrates into the voids of the paper material or processed paper, and therefore the adhesion to the plate is excellent due to the anchor effect.

There will be some temperature difference. For example, a copolymer of ethylene and acrylic acid is used as a synthetic resin for forming fins (for example, Evaflexx E manufactured by Mitsui Deyupon Polychemical Co., Ltd.).
EA), a copolymer of ethylene and methacrylic acid (for example, Niyukurel, a trade name of Mitsui Deyupon Polychemical Co., Ltd.)
When used, the melting temperature is 90 to 120 ° C.
A so-called hot melt adhesive prepared by mixing wax with a copolymer of ethylene and vinyl acetate is preferably used as the low melt temperature hot melt resin applied on the fins. The melting temperature of the hot melt adhesive can be arbitrarily changed in the temperature range of 60 to 120 ° C. by changing the kind or blending amount of wax. In this example, the hot melt adhesive having a melting temperature of 60 to 90 ° C. was used. .
