Abstract

PURPOSE:To enable unit member groups, laminated with high precision, to be bonded together at a stroke without exercising an influence on other adhesive, by a method wherein hot melt resin containing magnetic particles is applied to the end face, on the reverse side to a plate, of the fin of a unit member to which the fin is adhered by means of a hot melt adhesive. CONSTITUTION:A stringform fin material 2 is pulled out from a stocker 10 and is wound around an adhesion roller 15, where hot melt resin 3 is continuously applied to the one end face by means of a resin coating device 4. The fin material is fed on a flat plate 1, and is contact-bonded by means of a press roller 16. The plate 1 on which the fin material 2 is adhered is guided to a hot melt resin coating device 6, by which molten hot melt resin 5 containing magnetic particles is thinly applied to the top part of the fin material 2. The member coated with the hot melt resin 5 containing magnetic particles is fed to a cutting device 7, where the member is cut to a given length to form a unit member 19. After a plurality of the unit members 19 are laminated together and positioned, the laminate is fed to an induction heat generating device 9 as a load is applied thereto. Only the hot melt resin 5 containing magnetic particles is softened by induction heat generation for bonding.

９０号公報に開示されている。[Prior Art] A 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. They can be divided into counter-flow type, counter-flow type, and cross-flow type (including orthogonal and diagonal) based on the flow of the two fluids to exchange heat, but for air conditioners, counter-flow type The direct flow type is often used. The basic structure of this kind of thing is, for example,
It is disclosed in Publication No. 90.

が、生産性があまり高くなく、高コストでもあった。That is, as shown in the perspective view of FIG. 4, plates 101 for partitioning two fluids to be heat exchanged are stacked with corrugated fins 102 forming double rows of parallel flow paths interposed therebetween. In the heat exchange element 100 for air conditioning, the plate 101 is formed of processed paper based on a paper that has both heat conductivity and moisture permeability, and the fins 102 are also made of plate 101.
It is obtained by corrugating a similar paper material. The heat exchange element 100 includes a plate 1 shown in FIG.
It has been manufactured by making a unit member 103 consisting of 01 and fins 102 in advance and stacking a plurality of unit members 103 so that the parallel channels are alternately orthogonal to each other, but the productivity is too high. It was also expensive.

00, the members corresponding to the fins are rod-shaped or string-shaped ribs 2゜2 made of a non-metallic material that have good bonding properties with the plate 201, and the ribs 202 of arbitrary height and pitch are arranged on the plate 201 with high precision. The unit members 203 as shown in FIG. 7 are formed by applying an adhesive to the end surface of the solid rib 202 opposite to the plate 201 side, and then laminating and joining each unit member 203. .

利点がある。In each unit member 19 to which a high-frequency electric field is applied, only the hot-melt resin 5 containing magnetic fine particles softens due to the induced heat generation of the magnetic fine particles, exhibits adhesive properties, and bonds each other, functioning as a heat exchanger. This is a block of the unit member 19. This block is taken out from the frame and placed in a mounting frame for assembling equipment, forming a finished heat exchanger. The method of producing adhesiveness in the hot melt resin 5 by inductively generating heat using a high-frequency electric field makes it possible to narrow down the heating target, requires a short heating time, and is less likely to cause uneven heating, making it easy to obtain high-quality heat exchange elements. In addition, even if the hot melt resin 3 to which the fins are bonded has a lower melting point than the hot melt resin 5 that is heated later, no problem occurs, and there is an advantage that there are fewer restrictions on the hot melt resin 3.

得られる。[Effects of the Invention] As described above, according to the present invention, a unit member is formed by bonding a plurality of fins constituting parallel flow paths through which a heat medium flows on one side of a flat plate in parallel with hot melt resin. a step of applying a hot melt resin containing magnetic fine particles to the end surface of the fin on the opposite side to the plate; a step of applying hot melt resin containing magnetic fine particles to the end surface of the unit member opposite to the plate; aligning the end surface of the unit member coated with the hot melt resin with the other surface of the next plate; A step of stacking a plurality of unit members, and a step of bonding the stacked unit members to each other in a high frequency electric field,
When the unit members are laminated, the hot melt resin that joins the unit members to each other does not exhibit adhesive properties, so that the positions of the unit members can be adjusted with respect to each other. Therefore, unit members can be laminated quickly and accurately, and each unit member can be laminated together in a short time by developing adhesiveness in the hot melt resin at once without affecting the hot melt resin that has a bonding function. can be combined with other heat exchange elements, resulting in high quality heat exchange elements with high productivity.
