[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat exchanger having a laminated structure which is mainly used in the field of air conditioning for exchanging heat between fluids and a method for manufacturing the heat exchanger.

[0002]

2. Description of the Related Art In recent years, air conditioners such as heating and cooling have been developed and popularized, and as a living area using the air conditioners has expanded, the importance of an air conditioner heat exchanger capable of recovering temperature and humidity in ventilation has increased. ing. As such a heat exchanger, for example, those disclosed in JP-B-47-19990, JP-B-54-1054 and JP-B-51-2131 are widely adopted. Each of these has a basic structure in which partition plates having heat conductivity and moisture permeability are superposed in a plurality of layers at predetermined intervals with a spacing plate in between. The partition plate is a rectangular flat plate, and the spacing plate is a corrugated plate with a sawtooth or sinusoidal waveform whose projection plane matches the partition plate. They are sandwiched at an angle of 90 degrees or close thereto, and two systems of fluid passages for passing the primary air stream and the secondary air stream are formed in alternate layers between these layers.

The characteristics required for the partition plate of the heat exchanger are low air permeability and high moisture permeability. this is,
Without mixing the fresh air sucked indoors from the outdoors during use and the dirty air exhausted indoors to the outdoors,
In addition, it is required that the water vapor be efficiently transferred between the intake air and the exhaust air so that the latent heat and the latent heat can be exchanged. And as a material of the partition plate that can meet such demands, Japanese Patent Publication No. 58-4
Gas shields such as those shown in 6325 have been developed. This is obtained by impregnating or coating a water-soluble polymer substance containing lithium halide as a hygroscopic agent on the porous member. In addition, Japanese Patent Publication Sho 5
As disclosed in Japanese Patent Laid-Open No. 3-34663, a device for improving flame retardancy is also taken by mixing and impregnating or applying a guanidine-based flame retardant into a water-soluble polymer substance as needed. There is.

[0004]

In a heat exchanger in which a partition plate is composed of a moisture-permeable gas shield obtained by impregnating or coating a water-soluble polymer substance on a porous member as described above, the temperature and humidity during the summer season, etc. Under high conditions, the water absorption of the partition plate causes a part of the water-soluble polymer substance to melt, resulting in a blocking phenomenon, which causes the material to break during rewinding work such as corrugation. Also, this type of heat exchanger
It is manufactured by laminating a plurality of single-sided corrugated board structures obtained by adhering the material forming the spacing plate to the material forming the partition plate while corrugating them as a heat exchanger constituent member.

The corrugating process is mainly composed of upper and lower gear-shaped corrugators that rotate in mesh with each other for forming the spacer plate material, and a press roll that presses the partition plate material against the spacer plate material while rotating. The upper and lower corrugators and the press roll are usually maintained at a high temperature of 150 ° C. or higher in order to adjust the step shape of the spacing plate.
Therefore, a part of the water-soluble polymer substance of the partition plate material is melted by the heat of the press roll and easily fused to the press roll, and if the temperature of the press roll is lowered, the partition plate material will not be fused to the press roll. Although it can be prevented, if the temperature is lowered, the corrugated stepped shape collapses, making it unusable as a heat exchanger constituent member.

So far, the temperature of the press roll and the upper and lower corrugators are adjusted to a temperature at which fusion does not easily occur,
The feed speed is slowed to prevent the step shape from collapsing.
Therefore, the productivity is considerably low and the manufacturing cost is high. In addition, the heat exchanger component of the single-sided corrugated board structure,
Warping may occur due to absorption of moisture in the air,
Warpage may also occur due to the water content of the water-solvent adhesive used during lamination. Therefore, although the pressing work is performed in the laminating / bonding process to prevent the occurrence of warpage, this is a very complicated process.

Further, in this type of heat exchanger, since the heat exchange areas for temperature exchange and humidity exchange are different, the temperature exchange efficiency and the humidity exchange efficiency are different. For example, heat exchange is performed under the air condition in which the sensible heat ratio is different in summer and winter. However, there is also a problem in that there is a difference in enthalpy exchange efficiency.

The present invention has been made in order to solve the above-mentioned conventional problems, and its object is to provide a highly productive heat exchanger manufacturing method capable of increasing the speed of corrugating. It is to develop, to develop a manufacturing method of a heat exchanger with high productivity and flame retardance that can increase the speed of corrugating, and there is little difference in heat exchange efficiency between summer and winter. To obtain a heat exchanger, and to obtain a heat exchanger that can simplify the manufacturing process and promote cost reduction.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. Embodiment 1. The present embodiment shown in FIGS. 1 to 4 relates to a method for manufacturing a heat exchanger 1 having a hexahedral structure having a laminated structure as shown in FIG. 1, which is suitable for air conditioning. The heat exchanger 1 obtained by this manufacturing method has a structure in which thin partition members 2 having heat conductivity and moisture permeability are superposed and bonded to a plurality of layers at predetermined intervals with a space holding member 3 interposed therebetween. ing.
The partition member 2 that constitutes the heat exchanger 1 is configured as a square or rhombus flat plate, and the spacing member 3 is a corrugated plate having a sawtooth or sinusoidal waveform whose projected plane shape matches that of the partition member 2. Has been formed. A fluid for passing the primary air flow (a) and the secondary air flow (b) by sandwiching the spacing member 3 between the partition members 2 with the directions of the corrugations thereof alternately having an angle of 90 degrees or an angle close thereto. The passages 4 and the fluid passages 5 are formed every other layer between these layers.

This heat exchanger 1 is manufactured by laminating and bonding a heat exchanger constituting member 6 in which a spacing member 3 is bonded to one surface of a partition member 2 as shown in FIGS. 2 and 3. . As shown in FIG. 3, the heat exchanger constituent member 6 is a plate-shaped porous member 7 and has a moisture-permeable film 8 having an air-shielding function formed on one surface thereof by a chemical coating to form a partition member 2. It is continuously made by adhering the material 9 which becomes the space holding member 3 forming the fluid passages 4 and 5 to the surface of the wet film 8 side by corrugating.

As the porous member 7, a paper material having a thickness of about 60 to 120 μm and a basis weight of 25 to 150 (g / m ² ) and mainly composed of cellulose fibers is adopted. The moisture permeable film 8 is obtained by dissolving polyvinyl alcohol (PVA) or the like, which is a water-soluble polymer, in water, and further mixing lithium chloride as a hygroscopic agent and guanidine sulfamate as a flame retardant to obtain a chemical liquid for forming a moisture permeable film. There is. The chemical liquid for forming the moisture-permeable film is applied to one surface of the porous member 7 at a speed of about 10 to 50 m / min using a roll quarter, and immediately dried to be used as a material for the partition member, as shown in FIG. Send to a single facer device. Porous member 7 for partition member
The coating amount of the chemical solution after drying is 10 to 30 g / m ² .

The porous member 7 for the partition member has a moisture permeable film 8 formed on one surface thereof, thereby having an air shielding function, a moisture absorbing function, and a flame retarding function. The paper material serving as the spacing member 3 is fed into the single facer device, and is corrugated to continuously produce the heat exchanger component member 6 in the shape of a single-faced corrugated board.
The corrugation process is performed by forming the spacing member 3 and engaging upper and lower gear-shaped corrugators 10, 1 that rotate in mesh with each other.
1 and a press roll 1 for pressing the porous member 7 which is the material of the partition member 2 against the material 9 of the spacing member 3 while rotating.
2 and the sizing roll 13 are configured as the core,
In order to arrange the step shape of the spacing member 3, the upper and lower corrugators 10 and 11 and the press roll 12 are maintained at a high temperature at which the step shape can be easily adjusted. The gluing roll 13 applies a water-solvent-based vinyl acetate emulsion adhesive to the peak portion of the step of the material 9 of the stepped spacing member 3 delivered by the lower corrugator 11. The material of the partition member 2 is sent to the press roll 12 side with the surface without the moisture permeable membrane 8 facing.
The surface on the moisture permeable membrane 8 side is an adhesive surface to the material 9 of the spacing member 3. The heat exchanger constituent member 6 thus manufactured is cut, and the heat exchanger 1 as shown in FIG. 1 is manufactured by laminating and adhering the members by alternately changing the direction by 90 degrees.
It is also possible to obtain a counterflow heat exchanger by stacking the cut heat exchanger constituent members 6 with the directions of the corrugations of the spacing member 3 parallel.

The feature of the manufacturing method of this heat exchanger 1 is that FIG.
Even when the temperatures of the upper and lower corrugators 10 and 11 and the press roll 12 for adjusting the corrugated shape in the corrugating process are kept high, the press roll 12 does not have the moisture permeable membrane 8 and the press roll 12 is porous. Since the surface of the member 7 is in contact, the moisture permeable membrane 8 is not melted by heat and the porous member 7 which is the material of the partition member 2 is not fused to the press roll 12. It is possible to corrugate by increasing the feed speed at a high temperature that is easy to arrange. Corrugation can be performed at a feed speed that is about three times faster than the feed speed of conventional corrugation.
The productivity can be remarkably improved, and the processing cost can be reduced to about 1/3.

The same effect can be obtained by laminating a resin film using an organic material on one surface of the porous member 7 to form the moisture permeable film 8 and using it as the material of the partition member 2. Further, the moisture permeable membrane 8 is formed of a polyester film having a thickness of about 10 to 20 μm, and the spacing member 3
In the case of using a mixed paper material obtained by mixing polyester fibers and cellulose fibers of the same system, corrugation can be performed by heat fusion without using an adhesive,
It becomes possible to process at higher speed.

Embodiment 2. The present embodiment shown in FIGS. 5 and 6 relates to a method for manufacturing a heat exchanger suitable for air conditioning, which is formed into a hexahedron having a laminated structure as in the first embodiment. The manufacturing method of the present embodiment is also basically the same as the manufacturing method of the first embodiment except the composition of the partition member. Therefore, FIGS. 1 and 2 are incorporated by reference, and the same parts as those in the first embodiment are designated by the same reference numerals as those in the first embodiment and the description thereof is omitted.

Also in the heat exchanger 1 obtained by the manufacturing method of the present embodiment, as shown in FIG. 1, thin partition members 2 having heat conductivity and moisture permeability are provided at predetermined intervals with the spacing member 3 interposed therebetween. In this case, a plurality of layers are laminated and bonded. The partition member 2 that constitutes the heat exchanger 1 is configured as a square or rhombus flat plate, and the spacing member 3 is a corrugated plate having a sawtooth or sinusoidal waveform whose projected plane shape matches that of the partition member 2. Has been formed. The spacing member 3 is sandwiched between the partition members 2 with the directions of the corrugations thereof being alternately set at 90 degrees or an angle close thereto, and the primary air flow (a)
A fluid passage 4 and a fluid passage 5 through which the secondary air flow (b) passes are formed between these layers in alternate layers.

Also in this heat exchanger 1, as in the case of the first embodiment, a heat exchanger constituting member 6 in which a spacing member 3 is bonded to one surface of one partition member 2 as shown in FIG. 2 is laminated. It is manufactured by The heat exchanger constituent member 6 is a surface of the gas-permeable film 8 side of the gas shield which becomes the partition member 2 in which the moisture-permeable film 8 having an air-shielding function is formed on one surface of the plate-shaped porous member 7 by chemical coating. Then, the material 9 which becomes the spacing member 3 which constitutes the fluid passages 4 and 5 is continuously bonded by corrugating.

JI called flame-retardant paper is used for the porous member 7.
S. A1322 conforming product is used. This flame-retardant paper contains cellulose fibers mixed with the flame-retardant agent 14 at the stage of paper making, has a thickness of about 60 to 120 μm, and a basis weight of 25 to 150.
It is a paper material of (g / m ² ). As the flame retardant 14, a guanidine type is generally used, but guanidine sulfamate is suitable from the viewpoint of suitability for a single facer device and environmental considerations. The flame retardant 14 is mixed with 10 to 40% of the specific gravity of the base paper. By mixing the flame retardant 14 in advance, tackiness on the surface is reduced and handling becomes easier. Further, since the flame retardant 14 generally has high hygroscopicity, it is possible to improve the water content compared to untreated plain paper by selecting the flame retardant 14 having high hygroscopicity.

Regarding the moisture permeability, in the moisture permeability process in which the water molecules condensed on the surface layer of the partition member 2 move in the form of water through the capillaries formed in the fiber layer inside the partition member 2 and evaporate from the surface layer on the opposite surface, As shown in FIG. 6, the diameter of the capillary inside the partition member 2 becomes smaller by filling the flame retardant 14 between the cellulose fibers 15. Therefore, a smaller amount of water than before causes the capillary phenomenon and the water moves to the surface layer on the opposite surface. Easier to do. As a result, the heat exchanger 1 having excellent humidity exchange efficiency can be configured.

The moisture permeable film 8 is formed by dissolving polyvinyl alcohol (PVA), which is a water-soluble polymer, in water, and further mixing lithium chloride as a hygroscopic agent and guanidine sulfamate as a flame retardant to form a moisture permeable film. It is used as a drug solution. The chemical liquid for forming the moisture-permeable film is applied to one surface of the porous member 7 at a speed of about 30 to 70 m / min using a roll quarter, and immediately dried to be used as a material for the partition member 2, and the first embodiment is used. It is sent to the single facer device shown in FIG. The coating amount of the chemical liquid after drying the porous member 7 for the partition member 2 is about 5 to 15 g / m ² .

The flame-retardant paper material constituting the partition member 2 has a moisture permeable film 8 formed on one surface thereof, thereby having an air-shielding function, a moisture absorption function, and a flame-retardant function. The material 9 that mainly serves as the spacing member 3 is fed into the single facer device, and in the same manner as described in the first embodiment, the heat exchanger component member 6 that is corrugated and has a one-sided corrugated cardboard shape is formed. Manufactured continuously.
The heat exchanger constituent member 6 thus manufactured is cut, and the heat exchanger 1 as shown in FIG. 1 is manufactured by laminating and adhering the members by alternately changing the direction by 90 degrees. According to this manufacturing method, since the flame-retardant paper material that has been subjected to the flame-retardant treatment is used as the material of the partition member 2, the amount of the chemical liquid applied to form the moisture-permeable film 8 is smaller than that in the first embodiment. It can be reduced, and productivity can be further improved by increasing the speed of coating with the chemical liquid in the manufacturing process. Other effects are the same as those of the manufacturing method of the first embodiment.

Also in this embodiment, a counterflow type heat exchanger can be obtained by stacking the cut heat exchanger constituent members 6 so that the direction of the corrugation of the spacing member 3 is parallel. it can. Also, the same effect can be obtained by laminating a resin film using an organic material on one surface of the flame-retardant paper material to form the moisture permeable film 8 and using it as the material of the partition member 2. If the moisture permeable membrane 8 is formed of a polyester film having a thickness of about 10 to 20 μm and the spacing member 3 is made of a mixed paper material obtained by mixing polyester fibers and cellulose fibers of the same system, the adhesive can be used without using an adhesive. Since the corrugation process can be performed by heat fusion, the process can be performed at higher speed.

Embodiment 3. In the present embodiment shown in FIG. 7, the adhesive 16 is used to bond the heat exchanger constituent members 6 to each other when laminating the heat exchanger constituent members 6 obtained by the manufacturing method according to the first embodiment or the second embodiment. A method for manufacturing a heat exchanger using a flame retardant mixed with a flame retardant for emulsion resin addition, which is a mixture of a bromine compound and a metal oxide in a water solvent type vinyl acetate emulsion adhesive.

The heat exchanger constituent member 6 is alternately laminated and adhered by changing the direction by 90 degrees using such an adhesive 16 to form a porous member on which the moisture permeable film 8 is not formed by chemical coating or laminating. The flame retardancy of the surface No. 7 can be imparted by the adhesive agent 16, and the improvement of the flame retardance of the heat exchanger 1 as a whole can be promoted. A sample in which the heat exchanger constituent member 6 is adhered using the adhesive 16 and a sample in which the heat exchanger constituent member 6 is adhered using a normal vinyl acetate emulsion adhesive are specified in JIS. As a result of comparison by a combustion experiment of A1322, the carbonization length of the former was 7 cm, whereas the carbonization length of the latter was 8.6 cm, which confirmed that the flame retardancy was improved.

Heat exchanger component 6 by corrugating
A flame retardant for addition of an emulsion resin, in which a bromine compound and a metal oxide are mixed with a water solvent-based vinyl acetate emulsion adhesive for adhering the material of the partition member 2 and the material 9 of the spacing member 3 when manufacturing The flame retardancy of the heat exchanger 1 can be remarkably improved by using the adhesive containing the flame retardant.

Fourth Embodiment This embodiment shown in FIGS. 8, 9 and 10 is a stack of the heat exchanger constituent member 6 obtained by the manufacturing method of the first and second embodiments and the heat exchanger constituent member 17 of another structure. The present invention relates to a heat exchanger configured by adhesion.
The heat exchanger constituent member 6 shown in the first and second embodiments has a structure in which the material 9 of the spacing member 3 is bonded to the surface of the porous member 7 on the moisture permeable membrane 8 side. The heat exchanger component 6 is
A heat exchanger constituting member 17 having a constitution as shown in FIG. 9 in which the material 9 of the spacing member 3 has an opposite adhesive surface is formed, and the surfaces of the partition member 2 on the moisture permeable membrane 8 side of one fluid passage 4 face each other. As described above, the two types of heat exchanger constituent members 6 and 17 are alternately laminated and bonded as shown in FIG. 10 to form a heat exchanger.

Since the moisture permeable membrane 8 is formed on one surface of each of the two types of heat exchanger constituent members 6 and 17, the moisture permeability of the partition member 2 is different between the front and back sides, but the two types of heat exchanger configurations are used. By stacking the members 6 and 17 as shown in FIG. 10, when the humidity shifts from the fluid passage 5 to the fluid passage 4 and when the humidity shifts from the fluid passage 4 to the fluid passage 5,
The latter has a higher migration rate than the former. In the conventional heat exchanger with a laminated structure, since the humidity exchange efficiency is low in terms of temperature and humidity exchange efficiency, the total heat exchange efficiency becomes worse than the winter season in the summer when the ratio of humidity to the total heat is large. As in the heat exchanger of the above embodiment, the surfaces of the partition member 2 of one fluid passage 4 on the side of the moisture permeable membrane 8 face each other, and the fluid passage 5 on the high humidity side is formed under the conditions of summer. By using the passages facing each other, the difference in total heat exchange efficiency between summer and winter can be reduced, and the difference in enthalpy exchange efficiency between summer and winter can be reduced.

With the structure shown in this embodiment, the flat area 30
As a result of making a test with a heat exchanger having a size of 0 mm × 300 mm and a height of 500 mm, the difference in the total heat exchange efficiency between the conditions of summer and winter was improved by about 30%. As a result, it is possible to reduce the problems related to the air conditioning design that takes into consideration the difference in heat recovery between summer and winter. The configuration of the heat exchanger of this embodiment can be applied to not only the cross flow type but also the counter flow type heat exchanger in which the corrugations of the spacing member 3 are parallel.

Embodiment 5. The present embodiment shown in FIG. 11 also relates to a heat exchanger for air conditioning having a laminated structure in which the fluid passages of the two systems as shown in Embodiment 4 are configured to intersect or run in alternate layers. . In the heat exchanger of the present embodiment, the partition member 2 that partitions the fluid passages 4 and 5 and the spacing member 3 that holds the spacing between the partition members 2 are made of materials having different expansions on the front and back sides due to humidity. Then, the surface side of the spacing member 3 that easily expands due to humidity and the surface side of the partition member 2 that easily expands due to humidity are joined and laminated and bonded.

The spacing member 3 is made of a paper material, and one side thereof has a portion 18 relatively less stretched by moisture, and the other side thereof has a portion 19 greatly stretched by comparative moisture. The portion 18 with little elongation is configured as a glossy surface that is hardened and glossed in the drying step during paper making,
The portion 19 having a large elongation is configured as a normal paper surface without gloss processing. The partition member 2 is the partition member of the first or second embodiment.
In the corrugated processing, the gap holding member 3 is bonded to the moisture permeable film 8 side with the ridge portion of the surface on the side where expansion easily occurs. In the conventional heat exchanger, when the heat exchanger constituent members 6 are laminated and adhered, the water-solvent emulsion adhesive is applied to the crests of the gap holding member 3, but the gap is changed by the water content of the water-solvent emulsion adhesive. The holding member 3 was stretched and waviness was generated during stacking.

However, in the heat exchanger of the present embodiment, since the side of the spacing member 3 to which the water-solvent emulsion adhesive is applied is less likely to warp due to moisture, the warpage during stacking adhesion is reduced and waviness is reduced. It will be few. Therefore, it is not necessary to suppress the occurrence of warpage in the stacking / adhesion process, and it is not necessary to perform a pressing work to correct the warpage, and the productivity is improved. In addition, the corrugating process using a paper material that normally does not absorb water and a water-solvent adhesive requires a processing speed slower than usual because of the decrease in the adhesive force development speed. Since the water-absorbing surface which has not been processed is joined to the partition member 2, the adhesive force is developed at an early stage, and there is an effect that the corrugating process does not have to be slowed down. Further, since the surface of the partition member 2 on the side of the moisture permeable membrane 8 absorbs water and easily expands, the expansion force of the heat exchanger constituent member 6 can be increased by joining the surface of the spacing member 3 that easily expands with water. It can be canceled and the appearance quality of the whole heat exchanger is improved.

Sixth Embodiment In this embodiment, a moisture permeable film 8 having an air shielding function is formed on one surface of the porous member 7, and a chemical agent layer having a hygroscopic property is formed on the other surface. The present embodiment shown in FIGS. 12 to 15 relates to a heat exchanger 1 suitable for air conditioning, which has a hexahedral shape having a laminated structure as shown in FIG. 12, and a manufacturing method thereof.

In the heat exchanger 1 obtained by this manufacturing method, thin partition members 2 having heat conductivity and moisture permeability are superposed and adhered to a plurality of layers at predetermined intervals with a space holding member 3 interposed therebetween. It is composed. The partition member 2 that constitutes the heat exchanger 1 is configured as a square or rhombus flat plate, and the spacing member 3 is a corrugated plate having a sawtooth or sinusoidal waveform whose projected plane shape matches that of the partition member 2. Has been formed. A fluid for passing the primary air flow (a) and the secondary air flow (b) by sandwiching the spacing member 3 between the partition members 2 with the directions of the corrugations thereof alternately having an angle of 90 degrees or an angle close thereto. The passages 4 and the fluid passages 5 are formed every other layer between these layers.

This heat exchanger 1 is manufactured by laminating and bonding a heat exchanger constituting member 6 in which a spacing member 3 is bonded to one surface of one partition member 2 as shown in FIGS. 13 and 14. . As shown in FIG. 14, a moisture-permeable film 8 having an air-shielding function is formed on one surface of a plate-shaped porous member 7 by chemical solution coating, and on the other surface, a chemical solution (hygroscopic agent) 2 having a hygroscopic property is formed.
0 is applied to form the partition member 2, and the material 9 to be the space holding member 3 forming the fluid passages 4 and 5 is bonded to the surface of the partition member 2 on the moisture permeable membrane 8 side by corrugation. The heat exchanger component 6 is continuously manufactured by such a procedure.

As the porous member 7, a paper material having a thickness of about 60 to 120 μm and a basis weight of 25 to 150 (g / m ² ) and mainly composed of cellulose fibers is adopted. The moisture permeable film 8 is obtained by dissolving polyvinyl alcohol (PVA) or the like, which is a water-soluble polymer, in water, and further mixing lithium chloride as a hygroscopic agent and guanidine sulfamate as a flame retardant to obtain a chemical liquid for forming a moisture permeable film. There is.

The chemical liquid for forming the moisture-permeable film is applied to one surface of the porous member 7 at a speed of about 10 to 50 m / min using a roll quarter, and further, as a hygroscopic agent having less tackiness than the opposite surface, it is chlorinated. Lithium or the like is applied and immediately dried to obtain a material for the partition member, which is then fed into a single facer device as shown in FIG. The coating amount of the chemical liquid after drying the porous member 7 for the partition member is 10 to 30 g / m ² .

The porous member 7 for the partition member has a moisture permeable film 8 formed on one surface thereof, and thus has an air shielding function, a moisture absorbing function, and a flame retarding function. The paper material serving as the spacing member 3 is fed into the single facer device, and is corrugated to continuously produce the heat exchanger component member 6 in the shape of a single-faced corrugated board.

In the corrugating process, the upper and lower gear-shaped corrugators 10 and 11 that rotate in mesh with each other for forming the spacing member 3 and the porous member 7 that is the material of the partition member 2 are used as the material 9 of the spacing member 3. The press roll 12 and the sizing roll 13 that press while rotating are configured with the core as a core, and in order to arrange the step shape of the spacing member 3,
The upper and lower corrugators 10 and 11 and the press roll 12 are maintained at a high temperature where the step shape can be easily adjusted.

The gluing roll 13 applies a water-solvent-based vinyl acetate emulsion adhesive to the ridge portion of the step of the material 9 of the stepped spacing member 3 delivered by the lower corrugator 11. The material of the partition member 2 is fed toward the press roll 12 side with the surface without the moisture permeable film 8 (the surface on which the layer of the moisture absorbent 20 is formed), and the surface on the moisture permeable film 8 side is the material of the spacing member 3. It is supposed to be an adhesive surface with 9. The heat exchanger constituent member 6 thus manufactured is cut, and the heat exchanger 1 as shown in FIG. It is also possible to obtain a counterflow heat exchanger by stacking the cut heat exchanger constituent members 6 with the directions of the corrugations of the spacing member 3 parallel.

The feature of the manufacturing method of this heat exchanger 1 is that FIG.
Even when the temperatures of the upper and lower corrugators 10 and 11 and the press roll 12 for adjusting the step shape in the corrugating process shown in FIG. 5 are kept high, the moisture permeable film 8 is provided on the press roll 12 side.
Since the press roll 12 is covered with the layer of the hygroscopic agent 20 of the porous member 7 having low adhesiveness, the moisture permeable film 8 is exposed to heat.
Does not melt and the porous member 7, which is the material of the partition member 2, is fused to the press roll 12,
Corrugating can be performed by increasing the feed speed at high temperature, which makes it easy to arrange the step shape.

Therefore, the corrugating process can be performed at a feeding speed about three times faster than that of the conventional corrugating process, the productivity can be remarkably improved, and the machining cost can be reduced to about 1/3. can do.

Further, in this embodiment, since the layer of the moisture absorbent 20 is formed on one surface of the porous member 7, the moisture permeability can be improved. This point will be described in detail below.

When the moisture permeable film is formed only on one surface and the other one surface is not treated, moisture permeable from the moisture permeable film surface side due to the effect of the moisture absorbent contained in the moisture permeable film forming agent. The moisture permeability from the untreated side on the opposite side is lower than the performance. When a heat exchanger is configured using this partition member, the air passage for each layer is an air passage in which the moisture-permeable film-forming chemical liquid treatment surface and the uncoated surface are opposed to each other. Therefore, when heat exchange is performed using this heat exchanger, the moisture permeability becomes approximately the average value of the moisture permeability of the moisture-permeable film forming agent-treated surface and the uncoated surface.

On the other hand, as in the present embodiment, by forming the moisture permeable film 8 on one surface and applying lithium chloride, which is the moisture absorbent 20, to the other surface, the moisture permeability is improved and the front and back surfaces are The difference in moisture permeability is reduced. As a result, the average moisture permeability on the front and back sides can be improved much more effectively than improving the moisture permeability on the side of the moisture-permeable film forming chemical liquid treatment surface, and the moisture permeability can be easily increased as a heat exchanger. It becomes possible.

The same effect can be obtained even when a resin film using an organic material is laminated on one surface of the porous member 7 to form a moisture permeable film 8 and used as a material for the partition member 2. Further, the moisture permeable membrane 8 is formed of a polyester film having a thickness of about 10 to 20 μm, and the spacing member 3
In the case of using a mixed paper material obtained by mixing polyester fibers and cellulose fibers of the same system, corrugation can be performed by heat fusion without using an adhesive,
It becomes possible to process at higher speed.

Since the corrugation process can be performed by heat fusion, the process can be performed at higher speed.

Embodiment 8. In this embodiment, the procedure for applying the moisture absorbent 20 to the porous member 7 is different from that in the sixth embodiment. The present embodiment relates to a method for manufacturing a heat exchanger having a hexahedral structure having a laminated structure and suitable for air conditioning, as in the sixth embodiment. The manufacturing method of the present embodiment is also basically the same as the manufacturing method of the sixth embodiment except for the composition of the partition member.

It is a paper material of 150 (g / m ² ). As the flame retardant 14, a guanidine type is generally used, but guanidine sulfamate is suitable from the viewpoint of suitability for a single facer device and environmental considerations.

The flame retardant 14 is 10 to 40% in specific gravity of the base paper.
Are mixed. By mixing the flame retardant 14 in advance, tackiness on the surface is reduced and handling becomes easier. Further, since the flame retardant 14 generally has high hygroscopicity, it is possible to improve the water content compared to untreated plain paper by selecting the flame retardant 14 having high hygroscopicity.

The moisture permeable film 8 is formed by dissolving polyvinyl alcohol (PVA), which is a water-soluble polymer, in water, and further mixing lithium chloride as a hygroscopic agent and guanidine sulfamate as a flame retardant to form a moisture permeable film. It is used as a drug solution. Embodiment 6 The chemical liquid for forming the moisture-permeable film is applied to one surface of the porous member 7 at a speed of about 30 to 70 m / min using a roll quarter, and immediately dried to be used as a material for the partition member 2. It is sent to the single facer device shown in FIG. The coating amount of the chemical liquid after drying the porous member 7 for the partition member 2 is about 5 to 15 g / m ² . The hygroscopic agent 20 is not yet applied to the partition member 2 at the time of feeding it to the single facer device.

The flame-retardant paper material forming the partition member 2 has a moisture permeable film 8 formed on one surface thereof, which has an air-shielding function, a moisture-absorption function, and a flame-retardant function. The material 9 that mainly serves as the spacing member 3 is fed into the single facer device, and in the same manner as described in the sixth embodiment, the heat exchanger component member 6 that is corrugated and has a single-sided corrugated cardboard shape is formed. Manufactured continuously.
The heat exchanger constituent member 6 thus manufactured is cut, and the heat exchanger 1 as shown in FIG.

However, at the time of stacking and bonding, as shown in FIG. 17, an adhesive is applied to the peaks of the ridges of the spacing member 3 by the gluing roller 21. At the same time, the hygroscopic agent coating roller 22 applies the hygroscopic agent 20 dissolved in a water solvent to the surface of the partition member 2 on the side where the moisture permeable film 8 is not formed.

As a result, the moisture permeability of the heat exchanger can be greatly improved as in the sixth embodiment. In addition, the warp of the heat exchanger constituent member 6 caused by the moisture as the adhesive solution at the time of stacking that absorbs the moisture and expands the spacing member 3 similarly causes a chemical agent of a water solvent type (moisture absorption dissolved in a water solvent) from the opposite side. Agent 2
It is reduced by applying 0). Therefore, it is possible to suppress the warpage of the entire heat exchanger component member 6 to a small extent, which leads to an improvement in productivity.

Ninth Embodiment In this embodiment, the method of applying the adhesive to the spacing member 3 is different from that of the eighth embodiment, and the difference will be mainly described. The other parts are the same as those in the eighth embodiment, and the description thereof will be omitted.

The steps up to the continuous manufacturing of the heat exchanger component 6 are the same as in the eighth embodiment. Then, the heat exchanger constituent member 6 manufactured in this manner is cut, and the heat exchanger 1 as shown in FIG. 12 is manufactured by laminating and bonding by alternately changing the direction by 90 degrees. At the time of this lamination adhesion, FIG.
As shown in FIG. 5, the adhesive is applied to the entire surface including the peaks of the ridges of the spacing member 3 by the gluing roller 21, and at the same time, the hygroscopic agent coating roller 22 applies the hygroscopic agent dissolved in the water solvent. In the eighth embodiment, the adhesive is applied to the peaks of the crests of the spacing member 3, but in this embodiment, not only the peaks of the crests of the spacing member 3 but also the entire surface or substantially the entire surface including the valleys. Applying adhesive.

As a coating method, there are methods such as roller coating and spraying of chemicals, but it is sufficient that the entire surface or substantially the entire surface can be uniformly coated.

Normally, the spacing plate holding member 3 is made of a paper material in view of workability and price. However, if this material is porous and has low ventilation resistance, it will pass through the fluid passage 4 of the heat exchanger member. The flowing fluid passes through the spacing plate holding member 3 and laterally leaks as an air flow (c) as shown in FIG.

When the heat exchanger 1 is constructed by using such a heat exchanger constituting member 6, a part of the primary air flow (a) leaks to the secondary air flow (b) side as an air flow (c). As a result, the exhausted air mixes with the supply air, so the effect as a ventilation device is reduced.

Therefore, as in the present invention, a water solvent type vinyl acetate adhesive having adhesiveness and gas shielding function is applied to the spacing member 3 as an adhesive over the entire surface, so that the adhesive components are separated after drying. It remains on the surface of the plate holding member 3. Since this adhesive component has a gas-shielding function, a gas-shielding film is formed on the surface of the sensation-holding member 3, and it is possible to completely prevent airflow c leaking through the spacing-plate holding member 3. Therefore, it is effective in preventing leakage and mixing of exhaust gas and supply air when the heat exchanger is configured. Further, the same effect as that of the eighth embodiment can be obtained.

In this embodiment, the adhesive having the adhesiveness and the gas shielding function is applied. However, the chemical having the gas shielding function is applied, and then the adhesive is applied to the crest portion of the spacing member. May be.
