積層することにより製造していた。Plate-fin type heat exchange elements have a large heat transfer area per unit volume, and are widely used as relatively small and highly efficient heat exchange elements. It can be divided into three types: flow type, counter flow type, and orthogonal (oblique) flow type. Counter-flow type and cross-flow type are often used for air conditioners, and their basic configuration is described in Japanese Patent Publication No. 47-19990, and as shown in the perspective view of Figure 4, heat exchange type is used. (101) Wave-shaped fins (102) constituting a t-double row of parallel flow paths are sandwiched and stacked. In the heat exchange element (100) for air conditioning, the plate (101) is made of processed paper based on a paper material that has both heat conductivity and moisture permeability, and the fin (102)
) is also obtained by processing the same paper material as the plate (101) into a corrugated shape. The above heat exchange element (100)
A unit member (103) consisting of a plate (101) and a fin (102) as shown in the perspective view of FIG. It is obtained by laminating sheets. Specifically, the unit member (103) is made using a corrugating machine,
A fin (102) formed into a wave shape is bonded to a plate (101) using an adhesive such as vinyl acetate, and a heat exchange element (100) is attached to the top (104) of the fin of this unit member (103). It was manufactured by laminating layers while applying an adhesive such as vinyl acetate.

いた。Thereafter, 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.
was invented (Application filed by the same applicant on January 29, 1988, ``Heat Exchanger'' (Patent Application No. 61-(N7221)).In this, the members corresponding to the fins are made of synthetic resin. , play) On (201), fins (202) of arbitrary height and pitch are integrally molded with high accuracy to form a unit member (203) as shown in the perspective view of Fig. 7. End face (hereinafter referred to as the top part) (204
) was manufactured by laminating layers while applying adhesive.
ところが、フィンの頂上部に粘着性を有する接着剤を塗
布した単位部材を精度良く積層することは困難であり、
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
った。However, it is difficult to accurately laminate unit members coated with a sticky adhesive on the tops of the fins.
There was a problem that the performance and productivity of the heat exchange element were poor.
従っ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、−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 exhibit adhesion during the lamination process of unit members,
There is a need for a method that can join a group of unit members all at once after lamination is completed and each unit member is positioned.
この発明は上記のような問題点を解消するとともに、上
記要望を満たすためになされたもので。This invention was made in order to solve the above-mentioned problems and to meet the above-mentioned needs.
熱交換素子の性能向上が図れ、生産性に優れた熱交換素
