DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art In recent years, as air conditioners such as heating and cooling have been developed and spread, and as living spaces using air conditioners have expanded, the importance of air conditioner heat exchangers capable of recovering temperature and humidity in ventilation has also increased. ing. As such heat exchangers, those disclosed in, for example, JP-B-47-19990, JP-B-54-1054, and JP-B-51-2131 are widely employed. Each of these has a basic structure in which a partition plate having heat conductivity and moisture permeability is laminated on a plurality of layers at a predetermined interval with a spacing plate interposed therebetween. The partition plate is a square flat plate, and the spacing plate is a corrugated plate formed by shaping a sawtooth or sinusoidal waveform whose projection plane matches the partition plate, and the forming direction of the waveform alternates between the partition plates and the partition plate. It is sandwiched at an angle of 90 degrees or close to it, and two fluid passages for passing the primary airflow and the secondary airflow are formed alternately between these layers.

[0003] The characteristics required for the partition plate of the heat exchanger are low air permeability and high moisture permeability. this is,
Without mixing fresh air sucked into the room from the outside and dirty air exhausted from the room to the outside during use,
In addition, in order to exchange heat with latent heat at the same time as sensible heat, it is required that water vapor be efficiently transferred between intake air and exhaust air. As a material for a partition plate that can meet such demands, Japanese Patent Publication No. 58-4
A gas shield as disclosed in JP-A-6325 has been developed. This is obtained by impregnating or applying a water-soluble polymer substance containing lithium halide as a moisture absorbent to a porous member. In addition, Tokubo Sho 5
As disclosed in Japanese Patent Publication No. 3-34663, a measure has been taken to improve the flame retardancy by mixing and impregnating or applying a guanidine-based flame retardant in a water-soluble polymer substance as necessary. I have.

[0004]

In a heat exchanger in which a partition plate is constituted by a moisture-permeable gas shield obtained by impregnating or applying a water-soluble polymer substance to a porous member as described above, the temperature and humidity in summer and the like are high. Under high conditions, there is a problem that a part of the water-soluble polymer substance is dissolved due to moisture absorption of the partition plate, a blocking phenomenon occurs, and the material is broken at the time of rewinding operation such as corrugation. Also, this kind of heat exchanger
It is manufactured by laminating a plurality of single-sided corrugated cardboard structures obtained by adhering the material constituting the spacing plate to the material constituting the partition plate while corrugating the material as a heat exchanger constituting member.

[0005] The corrugating process is constituted mainly by a gear-shaped upper and lower corrugator, which rotates while meshing with each other, which forms the material of the spacing plate, and a press roll which presses the material of the partition plate while rotating against the material of the spacing plate. The upper and lower corrugators and press rolls 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 material of the material of the partition plate is melted by the heat of the press roll, and it is easy to fuse to the press roll. Although it can be prevented, when the temperature is lowered, the step shape of the corrugate is broken and the corrugate cannot be used as a heat exchanger component.

Therefore, hitherto, the temperature of the press roll and the upper and lower corrugators has been adjusted to a temperature at which fusion is unlikely to occur.
The feed speed is reduced to prevent the step shape from collapsing.
Therefore, the productivity is considerably low and the production cost is high. The heat exchanger components of the single-sided cardboard structure are:
Warping occurs by absorbing moisture in the air,
Warpage may also occur due to the water content of the aqueous solvent adhesive used during lamination. Therefore, the pressing operation is performed in the laminating / adhering process to prevent the occurrence of warpage, but this is a very complicated process.

Further, in this type of heat exchanger, the heat exchange areas for the temperature exchange and the humidity exchange are different, so that the temperature exchange efficiency and the humidity exchange efficiency are different. For example, the heat exchange is performed under air conditions in which the sensible heat ratio differs between summer and winter. There is also a problem that the enthalpy exchange efficiency becomes different when the above is performed.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a method of manufacturing a heat exchanger having high productivity which can increase the speed of corrugating. The goal is to develop a method of manufacturing a highly heat-resistant heat exchanger that can increase the speed of corrugating with a small difference in heat exchange efficiency between summer and winter. It is an object of the present invention to provide a heat exchanger which can simplify a manufacturing process and promote cost reduction.

The passages 4 and the fluid passages 5 are arranged alternately between these layers.

The heat exchanger 1 is manufactured by laminating and adhering a heat exchanger component 6 in which a spacing member 3 is adhered to one surface of a single partition member 2 as shown in FIGS. . As shown in FIG. 3, the heat exchanger component member 6 is formed of a plate-shaped porous member 7 on one side of which a moisture-permeable film 8 having an air-shielding function is formed by chemical liquid coating.

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

As shown in FIG. 1, the heat exchanger 1 obtained by the manufacturing method according to the present embodiment also includes a thin partition member 2 having heat conductivity and moisture permeability, and a predetermined gap between the thin partition member 2 and the spacing member 3. Here, it is configured to be laminated and adhered to a plurality of layers. The partition member 2 constituting the heat exchanger 1 is configured as a square or rhombic flat plate, and the spacing member 3 is formed into a corrugated sheet having a sawtooth or sinusoidal waveform whose projected plane shape matches the partition member 2. Is formed. The spacing member 3 is sandwiched between the partition members 2 with the direction of the wave eyes alternately at an angle of 90 degrees or close thereto, and the primary air flow (a)
And a fluid passage 4 and a fluid passage 5 for passing the secondary airflow (b) are provided alternately between these layers.

In this heat exchanger 1, as in the first embodiment, a heat exchanger component 6 in which a spacing member 3 is adhered to one surface of a single partition member 2 as shown in FIG. It is manufactured by The heat exchanger constituent member 6 is a surface of the gas shielding material on the moisture permeable film 8 side of the gas shielding material that becomes the partition member 2 in which a moisture permeable film 8 having an air shielding function is formed on one surface of a plate-shaped porous member 7 by applying a chemical solution. Then, a material 9 serving as the spacing member 3 constituting the fluid passages 4 and 5 is continuously formed by bonding by corrugating.

The porous member 7 has a JI called flame retardant paper.
S. A1322 compliant product is used. This flame-retardant paper is obtained by mixing the flame retardant 14 with cellulose fibers at the stage of paper making, has a thickness of about 60 to 120 μm, and has a basis weight of 25 to 150.
(G / m ² ) paper material. A guanidine-based flame retardant 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 at a specific gravity of the base paper of 10 to 40%. By blending the flame retardant 14 in advance, the stickiness of the surface is reduced and handling becomes easier. Further, since the flame retardant 14 generally has high hygroscopicity, the moisture content can be improved more than untreated plain paper by selecting the flame retardant 14 of a system having high hygroscopicity.

Regarding the moisture permeability, the water molecules condensed in the surface layer of the partition member 2 move in the form of water through the capillary formed in the fiber layer inside the partition member 2 and evaporate from the opposite surface layer. As shown in FIG. 6, when the flame retardant 14 is filled between the cellulose fibers 15, the diameter of the capillary inside the partition member 2 becomes smaller, so that a smaller amount of moisture causes a capillary phenomenon to occur and moisture moves to the opposite surface layer. 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) or the like, which is a water-soluble polymer substance, in water, and further mixing lithium chloride as a hygroscopic agent and guanidine sulfamate as a flame retardant to form a moisture-permeable film. Of chemicals. The liquid chemical for forming a moisture permeable film is applied to one surface of the porous member 7 at a speed of about 30 to 70 m / min by using a roll quarter, and immediately dried to obtain a material for the partition member 2. Is fed into a single facer device as shown in FIG. The applied amount of the chemical solution of the porous member 7 for the partition member 2 after drying 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 side, thereby having an air-shielding function, a moisture-absorbing function, and a flame-retardant function. Is mainly fed into the single facer device, and corrugated to form a single-sided cardboard heat exchanger component 6 in the same manner as described in the first embodiment. Manufactured continuously.
The heat exchanger component 6 manufactured as described above is cut, and alternately turned 90 degrees to be laminated and adhered, whereby the heat exchanger 1 as shown in FIG. 1 is manufactured. 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 solution applied to form the moisture-permeable film 8 is smaller than that of the first embodiment. The productivity can be further improved by increasing the chemical solution coating speed in the manufacturing process. Other effects are the same as those of the manufacturing method of the first embodiment.

In this embodiment, too, a counter-flow type heat exchanger can be obtained by laminating the cut heat exchanger components 6 in parallel with the direction of the waves of the spacing members 3. it can. 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 the film 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 in which the same polyester fiber and cellulose fiber are mixed, the adhesive is not used. Since corrugation can be performed by heat fusion, processing can be performed at a higher speed.

Embodiment 3 FIG. In the present embodiment shown in FIG. 7, the adhesive 16 is used for bonding the heat exchanger components 6 when the heat exchanger components 6 obtained by the manufacturing method of the first and second embodiments are laminated. And a method for manufacturing a heat exchanger using a flame retardant mixed with a flame retardant for adding an emulsion resin in which a bromine compound and a metal oxide are mixed with an aqueous solvent-based vinyl acetate emulsion adhesive.

The heat exchanger components 6 are alternately laminated and bonded by changing the direction by 90 degrees using such an adhesive 16 so that the porous member which does not form the moisture permeable membrane 8 by chemical liquid coating or laminating is formed. The flame retardancy of the surface 7 can be imparted by the adhesive 16, and the improvement of the flame retardancy of the heat exchanger 1 as a whole can be promoted. A sample in which the heat exchanger component 6 is bonded using the adhesive 16 and a sample in which the heat exchanger component 6 is bonded using a normal vinyl acetate emulsion adhesive are described in JIS. Comparison with A1322 combustion experiment revealed that the former carbonization length was 7 cm and the latter carbonization length was 8.6 cm, confirming that the flame retardancy was improved.

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

Embodiment 4 FIG. The present embodiment shown in FIGS. 8, 9 and 10 is a laminate of the heat exchanger component 6 obtained by the manufacturing method of the first and second embodiments and the heat exchanger component 17 of another configuration. The present invention relates to a heat exchanger formed by bonding. The heat exchanger component 6 described in the first and second embodiments has a configuration 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. With the heat exchanger component 6, a heat exchanger component 17 having a configuration as shown in FIG. 9 in which the adhesive surface of the material 9 of the spacing member 3 is opposite to that of FIG. As shown in FIG. 10, two types of heat exchanger constituent members 6, 17 are alternately laminated and bonded so that the surfaces on the side of the moisture permeable membrane 8 face each other to form a heat exchanger.

Although the two types of heat exchanger components 6 and 17 each have the moisture permeable film 8 formed on one side, the moisture permeability of the partition member 2 is different between the front and back sides. By laminating 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 transition rate than the former. In conventional heat exchangers with a laminated structure, the humidity and heat exchange efficiency of the temperature and humidity exchange efficiency are low, so in summer when the ratio of humidity to total heat is large, the total heat exchange efficiency is worse than in winter, but this implementation As in the heat exchanger of the embodiment, the surfaces of the partition member 2 of the one fluid passage 4 on the moisture permeable membrane 8 side face each other, and the fluid passage 5 on the high humidity side is connected to the moisture permeable membrane 8 in summer conditions. , The difference in the 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.

In the structure shown in the present embodiment, the plane area 30
A heat exchanger having a size of 0 mm x 300 mm and a height of 500 mm was prepared and tested. As a result, the difference in total heat exchange efficiency between the summer and winter conditions was improved by about 30%. As a result, it is possible to reduce problems related to the air conditioning design that takes into account the difference in heat recovery between summer and winter. The configuration of the heat exchanger according to the present embodiment can be applied to not only a cross-flow type heat exchanger but also a counter-flow type heat exchanger in which the crests of the spacing member 3 are parallel.

Embodiment 5 FIG. The present embodiment shown in FIG. 11 also relates to a heat exchanger for air-conditioning having a laminated structure in which two fluid passages as shown in the fourth embodiment are configured to intersect or parallel every other layer. . In the heat exchanger of the present embodiment, the partition member 2 for partitioning the fluid passages 4 and 5 and the spacing member 3 for maintaining the spacing between the partition members 2 are made of materials having different elongation due to humidity on both sides. Then, the surface side of the spacing member 3 that is easily stretched by humidity and the surface side of the partition member 2 that is easily stretched by humidity are joined and laminated and bonded.

The spacing member 3 is made of a paper material, and has a portion 18 on one side which is relatively low in elongation due to moisture, and a portion 19 on the other side which is large in expansion due to comparative enemy water. The low elongation portion 18 is configured as a glossy surface that is hardened in a drying process during papermaking and has a gloss.
The portion 19 with large elongation is configured as a normal paper surface without gloss processing. The partition member 2 is the same as in the first and second embodiments.
In the corrugating process, the ridge of the surface on the side where the spacing member 3 is easily stretched is bonded to the moisture permeable film 8 side. In the conventional heat exchanger, when laminating and adhering the heat exchanger constituent members 6, the aqueous solvent-based emulsion adhesive is applied to the ridge portion of the spacing member 3, but the spacing is caused by the moisture of the aqueous solvent-based emulsion adhesive. The holding member 3 was elongated, and undulation occurred during lamination.

However, in the heat exchanger of the present embodiment, the side of the spacing member 3 to which the aqueous solvent-based emulsion adhesive is applied is hardly warped due to moisture. Less. Therefore, it is not necessary to perform the pressing operation for suppressing the warpage or correcting the warpage in the laminating / adhering process, and the productivity is improved. In addition, in the corrugating process using a paper material that is usually hard to absorb water and a water-based adhesive, the processing speed must be lower than usual in order to decrease the speed of developing the adhesive force. Since the non-processed water-absorbing surface is joined to the partition member 2, the adhesive force is developed early, and there is an effect that the speed of the corrugating process does not need to be reduced. Since the surface of the partition member 2 on the moisture permeable membrane 8 side absorbs moisture and is easily stretched, by joining the surface of the spacing member 3 which is easily stretched by moisture, the stretching force of the heat exchanger component member 6 is reduced. It can be counteracted and the overall appearance of the heat exchanger is improved.

Embodiment 6 FIG. In this embodiment, a porous member 7 is formed on one surface with a moisture-permeable film 8 having an air-shielding function, and on the other surface with a drug layer having a moisture absorbing property.

The heat exchanger component 6 manufactured as described above is cut and alternately turned 90 degrees, and laminated and adhered, whereby the heat exchanger 1 as shown in FIG. 12 is manufactured. Note that a counter-flow heat exchanger can also be obtained by laminating the cut heat exchanger constituent members 6 with the direction of the waves of the spacing members 3 parallel.

The feature of the method of manufacturing the heat exchanger 1 is shown in FIG.
In the corrugating shown in FIG. 5, even if the temperatures of the upper and lower corrugators 10 and 11 and the press roll 12 for adjusting the step shape are kept high, the moisture permeable film 8 is formed on the press roll 12 side.
And the press roll 12 is exposed to a layer of the hygroscopic agent 20 of the porous member 7 having low adhesiveness.
Is not melted and the porous member 7 which is the material of the partition member 2 is fused to the press roll 12.
This means that corrugating can be performed by increasing the feed speed under high temperatures where it is easy to adjust the step shape.

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

When a moisture permeable film is formed only on one surface and the other surface is not treated, moisture permeable from the moisture permeable film surface side is caused by 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 path for each layer is an air path in which the surface treated with the chemical liquid forming the moisture-permeable film and the uncoated surface are opposed to each other. Therefore, when heat exchange is performed using this heat exchanger, the moisture permeability becomes an average value of the moisture permeability of the treated surface and the uncoated surface.

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

A similar effect can be obtained by laminating a resin film using an organic material on one surface of the porous member 7 to form a moisture-permeable film 8 and using the film as a 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,
In addition, if a mixed paper material obtained by mixing similar polyester fibers and cellulose fibers is used, corrugation can be performed by heat fusion without using an adhesive,
Processing can be performed at a higher speed.

In the eighth embodiment, the adhesive is applied to the apex of the crest of the spacing member 3. However, in this embodiment, not only the apex of the crest of the spacing member 3 but also the entire surface including the trough or almost the entire surface. Adhesive is applied.

As a method of coating, there are methods such as roller coating and spraying of chemicals, but it is sufficient that the coating can be performed on the entire surface or almost the entire surface without unevenness.

Normally, a paper material is used for the spacing plate holding member 3 in terms of workability and cost. However, if the material is porous and has low airflow resistance, it passes through the fluid passage 4 of the heat exchanger member. As shown in FIG. 19, the flowing fluid leaks laterally as airflow (c) through the spacing plate holding member 3.

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

Thus, by applying an aqueous solvent type vinyl acetate adhesive having an adhesive property and a gas shielding function as an adhesive on the entire surface of the spacing member 3 as in the present invention, the adhesive component is removed 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 sense-holding member 3, so that airflow leaking through the spacing plate holding member 3 can be completely prevented. Therefore, it is effective in preventing leakage and mixing of exhaust gas and air supply when a heat exchanger is configured. In addition, the same effect as that of the eighth embodiment can be obtained.

In this embodiment, an adhesive having an adhesive property and a gas-shielding function is applied. However, an agent having a gas-shielding function is applied, and then the adhesive is applied to a peak portion of the spacing member. You may.
