また加熱方法としては、INDUSTRIAL FIELD OF APPLICATION The present invention relates to a method of manufacturing a plastic heat exchanger. Conventional technology The conventional manufacturing method for plastic heat exchangers involves extruding a plastic heat transfer core, molding an end plate, assembling the plastic heat transfer core and end plate, and then joining the plastic heat transfer core and end plate. The company was manufacturing plastic heat exchangers. The plastic heat transfer core and the mirror plate have been joined using heat welding and adhesive methods. However, the above method for manufacturing a plastic heat exchanger requires a plastic heat transfer core extrusion machine, an assembly machine, and the equipment costs are high. It took a long time to assemble the heat exchanger and the end plate, and the time cost per heat exchanger increased, resulting in high manufacturing costs. Furthermore, the thinner the plastic heat transfer core of the plastic heat exchanger, the better the heat transfer performance, but the adhesive strength between the plastic heat transfer core and the mirror plate was poor. Purpose of the Invention The present invention has been made in view of the above circumstances, and it is possible to mold the entire plastic heat transfer core at once, thereby eliminating the need for a plastic heat transfer core extrusion machine and assembly machine, reducing equipment costs, and reducing the cost of ψ plates. and the plastic heat transfer core when forming the combined core, eliminating the assembly and bonding process of the plastic heat transfer core and bowl plate, reducing the time cost per heat exchanger and reducing manufacturing costs. purpose. Means and Effects for Solving the Problems In order to achieve the above objects, the present invention provides the following features:
A plurality of cores 2 are removably inserted into the mirror plates 3 and 4 to form a mold A, and after immersing the mold A in a plastic solution 9, the mold A is pulled out from the plastic solution 9. A plastic film 12 is formed on the surface of the mirror plates 3 and 4.
In this method, a joint core 11 is created between a heat transfer core 10 and a plastic heat transfer core 10 made of a plastic film 12, and the core is separated from this joint core 11. Embodiments Hereinafter, embodiments of the present invention will be explained based on the drawings. 1st
In the figure, reference numeral 1 denotes a core mounting plate, and a plurality of cores 2 are mounted parallel to each other at predetermined intervals to this core mounting plate 1. Reference numerals 3 and 4 in the drawings indicate mirror plates, and these mirror plates 3 and 4 are provided with a plurality of parallel insertion holes 5 and 6 spaced apart from each other by the same distance as the core 2. Further, 7 in the drawing is a guide, and the guide 7 has a plurality of guide holes 8 formed at the same intervals as the core 2. Then, overlap the mirror plates 3 and 4 as shown in FIG.
- Overlap the guide 7 on the mirror plate 3 and insert the guide hole 8 and the insertion hole 5.
, 6 to match each other. In this state, insert the core 2 into the guide hole 8.
Insert. Next, move the core mounting plate 1 as shown in FIG.
Insert it. Next, as shown in FIG. 3, the other mirror plate 4 is moved to the lower blade to obtain the molded saint 8. Next, as shown in Fig. 4, this mold hGIF, the end plate 3,
4 and the core 2 are immersed in a plastic solution 9 in which a thermoplastic resin is dissolved in a solvent, then the mold A is taken out of the plastic solution 9, and the mold A is heated as shown in FIG. As shown, a heat transfer core 10 made of a plastic film 12 is formed on the outer periphery of the core 2 of the molded saint. Next, by moving the core mounting plate 1 as shown in FIG. 6, the core 2 is separated from the joint core 11 consisting of the end plate 3.4 and the heat transfer core 10, and the joint core 11 shown in FIG.

Further, when the cores 2 are to be separated from the joint core 11, cold water may be flowed through the cores 2 to shrink the cores 2 so that they can be easily separated. What about the above-mentioned combined core 11? In the M manufacturing process, a necessary force S for heating the plastic solution 9 in the mold A is applied.
This is to obtain a high-quality plastic film 12 without bubbles; in the case of natural drying, only the outside of the plastic solution 9 on the surface of the mold A hardened, and the inside part did not dry, leaving the plastic solution 9. This is because it becomes a state. Also, as a heating method,

(2ν For plastic materials that cannot be heated by high-frequency dielectric heating, mold A is made of an electromagnetic material and high-frequency dielectric heating is performed. A hole 13 is provided, and heating is performed using this hole 13 (see Fig. 8). (41 Heating is performed by irradiating microwaves whose wavelength is matched to the natural frequency of the solvent in the plastic solution 9. In the above-mentioned example, a nylon 6.6 thermoplastic resin is used as the main ingredient for the plastic solution 9, formic acid is used as the solvent, and nylon 6.6 is used as the material for the mirror plates 3 and 4. ．．
The experiment was carried out using 6 resins. In addition, when forming the plastic film 12 on the surface of the molded saint, the atmosphere was kept in a vacuum state, and vacuum evaporation was used in combination, or mold A was subjected to high-frequency heating while being used in combination with hot air drying. Further, the thickness of the plastic film 12 can be freely controlled by adjusting the concentration of the solvent, and if a plurality of plastic solutions 9 are used, the plastic film 12 can be made into multiple layers. Further, if a filler such as a metal is mixed into the plastic solution 9, the filler can be mixed into the plastic film 12. Moreover, since the plastic is melted using a solvent, compared to a molding method in which the plastic is melted using heat, it is not possible to save energy in manufacturing. As another example, when the bonding core (1) is made of a thermosetting resin, the main ingredient as the plastic solution 9 is an unsaturated polyester (acid M - maleic acid, fumaric acid, etc., glycols - ethylene glycol, etc., vinyl monomer styrene). Monomer) was carried out using benzoyl peroxide as a curing agent. In this case, the mold A was immersed in a plastic solution 9 consisting of a thermosetting resin in a solution state, and then the mold mh was pulled out of the plastic bath liquid 9. , heat and harden the plastic solution 9 on the surface of the molded saint to form a plastic film 12.
Ru. The plastic solution 98 can be cured by heating from the outside of the molded saint or by heating the mold A itself. In addition, in the case of resins that can be cured by irradiation with ultraviolet rays, the outside of the molded saint or the molded saint itself is made of a light-transmissive material such as glass, and the molded saint is irradiated with ultraviolet rays, etc. from the inside. and harden. Furthermore, in the case of an electron beam irradiation-curable resin, etc., the resin is cured by irradiating it from the outside of the molded saint. When the plastic film 12 is formed using a resin curable by thermal light irradiation or electron beam irradiation as described above, a high quality plastic film 12 without bubbles can be obtained. Effects of the Invention As detailed above, the method for manufacturing a plastic heat exchanger according to the present invention includes a plurality of cores 2 on end plates 3° 4 facing each other.
is removably inserted to constitute a mold A, and this mold A
After immersing the mold A in the plastic solution 9, the mold A is pulled out from the plastic solution 9, a plastic film 12 is formed on the surface of the mold A, and the coupling core 11 is formed between the mirror plates 3, 4 and the plastic heat transfer core 10 made of the plastic film 12. This is characterized in that the core 2 is detached from the joint core 1. Therefore, it becomes possible to mold all the plastic heat transfer cores at once, eliminating the need for plastic tube extrusion machines and assembly machines, reducing equipment costs, and also making it possible to mold the plastic heat transfer core 10 in its entirety. Since the bonding is performed at the time of forming the bonding core 11, the conventional process of assembling the plastic heat transfer core and the end plate and bonding process of the plastic heat transfer core and the end plate can be replaced with the conventional steps. Therefore, the time cost per heat exchanger can be reduced and the manufacturing cost can be reduced.
