Description

Technical Field

[0001] The present invention relates to a manufacturing method of a counter-flow total heat exchanger, and particularly to a manufacturing method of a counter-flow total heat exchanger that forms a flow path for supplying external gas and discharging internal gas using a resin plate and is easy to mass-produce. Background Art

[0002] Generally speaking, for building structures from residential houses to buildings, department stores, theaters, shops, schools, and even hospitals, ventilation is an important component. However, during ventilation, the indoor air cooled or heated by refrigeration equipment or heating equipment is discharged to the outside, resulting in the problem of reduced indoor cooling and heating effects. To improve the above problems, a ventilation device equipped with a total heat exchanger has been developed.

[0003] Existing total heat exchangers are divided into cross flow, parallel flow, and counter flow. Among them, because the counter-flow total heat exchanger has the highest heat exchange efficiency, its application range is the widest.

[0004] Figure 1 FIG. 15 is a perspective view showing the structure of an existing counter-flow total heat exchanger 30. In the existing counter-flow total heat exchanger 30 shown in the figure, an external gas supply unit 31 for supplying outdoor air A to the indoor and an internal gas discharge unit 33 for discharging indoor air B to the outside are alternately stacked, and a total heat film paper 35 is interposed therebetween.

[0005] Figure 2 FIGS. 19(a) and (b) are perspective views separately showing the external gas supply unit 31 and the internal gas discharge unit 33 of the counter-flow total heat exchanger 30. As shown in the figure, the external gas supply unit 31 and the internal gas discharge unit 33 are respectively formed in the form of corrugated paper with a flow path for gas movement formed therein. At this time, each external gas supply unit 31 is formed in a manner that communicates with an external gas inlet pipe 31a, an external gas guide pipe 31b, and an external gas outlet pipe 31c, and each internal gas discharge unit 33 is formed in a manner that communicates with an internal gas inlet pipe 33a, an internal gas guide pipe 33b, and an internal gas outlet pipe 33c.

[0006] Among them, the internal gas guide pipe 33b is formed side by side with the external gas guide pipe 31b, and the internal gas inlet pipe 33a and the internal gas outlet pipe 33c are formed to be inclined in a direction opposite to that of the external gas inlet pipe 31a and the external gas outlet pipe 31c.

[0007] Thereby, the supply direction of the outdoor air A and the exhaust direction of the indoor air B are configured to be reverse to each other, so as to achieve total heat exchange during this process.

[0008] However, the external gas supply part and the internal gas discharge part of the existing counterflow total heat exchanger 30 are formed of resin, and only the total heat film paper is made of paper.

[0009] In the case where the materials of the total heat film paper, the external gas supply part, and the internal gas discharge part are different as described above, there is a problem that moisture exchange cannot be smoothly completed.

[0010] The humidity difference between winter and summer in South Korea is relatively large, so its humidity load is also high. In the above-described environment, it is particularly important to smoothly complete moisture exchange in the total heat exchanger. However, since the counterflow total heat exchanger is made of different materials structurally, on the flow paths where the indoor air and the outdoor air move, it is necessary for a solid surface to absorb moisture and then transfer the moisture to the other side. At this time, moisture cannot be smoothly transferred when the materials are different from each other.

[0011] In order to solve the above-described problems, in Korean Patent No. 10-0911776 "Total Heat Exchanger and Manufacturing Method of Total Heat Exchanger", a manufacturing method is proposed in which the total heat film paper, the external gas supply part, and the suction guide part are all formed of paper by a roll-to-roll method.

[0012] However, as shown in the prior art Figure 3 a flow path 51 in which peaks and valleys are repeated is formed on the paper 50 by inserting the paper 50 between a pair of rollers 40, 40a formed with concavities and convexities in opposite directions.

[0013] However, although theoretically the flow path 51 can be formed on the paper 50 in the above-described manner, in practice, since paper is a material with almost no deformation amount, it is difficult to maintain the shape of the peaks and valleys, so actual processing cannot be carried out.

[0014] That is, in order to form the desired flow path 51 using the paper 50, it is required that the thickness of the paper 50 is thick enough, but in the above-described case, there will be a problem of reduced heat exchange performance, and when the thickness of the paper 50 is thin, there will be problems of tearing or difficulty in maintaining the processed shape. Summary of the Invention

[0015] Technical Problem to be Solved

[0016] An object of the present invention is to provide a manufacturing method of a counterflow total heat exchanger that can directly manufacture a counterflow total heat exchanger using an existing roll-to-roll device to solve the above-described problems.

[0017] Another object of the present invention is to provide a method for manufacturing a counterflow total heat exchanger that can form an air moving flow path in contact with the inner lining with paper as well, while improving the heat transfer efficiency and smoothly completing moisture transfer.

[0018] Still another object of the present invention is to provide a method for manufacturing a counterflow total heat exchanger that can easily manufacture a counterflow total heat exchanger without using complex manufacturing devices.

[0019] Technical solution

[0020] The object of the present invention as described above can be achieved by a method for manufacturing a counterflow total heat exchanger. The method for manufacturing a counterflow total heat exchanger of the present invention includes the following steps: inserting a first paper with a first width between a pair of rollers 210, 210a having protrusions formed on the surface to form a hollow plate T having flow paths 111c, 121c formed on a single side surface; pasting the hollow plate T in the middle region of a second paper with a second width greater than the first width; cutting the second paper with the hollow plate T pasted thereon into a length corresponding to the guide corrugated papers 111, 121; and cutting the second paper into an inner lining 130 having resin tube joint surfaces 133 formed in a triangular shape on both sides of the cut guide corrugated papers 111, 121.

[0021] In addition, it further includes: cutting a resin plate 300 having a plurality of air moving channels formed side by side inside into a plurality of resin tubes 115, 117, 125, 127 corresponding to the shape of the resin tube joint surface 133; pasting the pair of cut resin tubes 115, 117, 125, 127 onto the resin tube joint surfaces 133 on both sides of the inner lining 130 in such a manner that the air moving channels 340 communicate with the flow paths 111c, 121c; and pasting a plurality of inner linings 130 having the guide corrugated papers 111, 121 and the pair of resin tubes 115, 117, 125, 127 joined to the upper side surface along the height direction; preferably.

[0022] Advantages of the invention

[0023] The method for manufacturing a counterflow total heat exchanger of the present invention can manufacture general paper into an external gas guide corrugated paper, an internal gas guide corrugated paper, and an inner lining using an existing roll-to-roll device.

[0024] In addition, the external gas supply part and the internal gas discharge part can be easily manufactured by cutting a commercially available resin plate into resin tubes and pasting them into the inner lining. In addition, the external gas supply part and the internal gas discharge part manufactured in the above-described manner can be alternately laminated with each other.

[0025] Accordingly, it is possible to manufacture the counterflow total heat exchanger without a separate special device, only using existing roll-to-roll devices, cutting equipment, and pasting equipment, thereby saving manufacturing costs.

[0026] In addition, since the inner lining, the external gas guiding corrugated paper, and the internal gas guiding corrugated paper of the counterflow total heat exchanger manufactured in the above-described manner are formed of the same paper, it also has the advantages of high heat transfer efficiency and high moisture transfer efficiency.

[0059] Next, the present invention will be described in detail with reference to the preferred embodiments of the present invention and the accompanying drawings, wherein the same reference numerals in the drawings represent the same components.

[0060] In the detailed description or claims of the invention, when it is described that a certain component "comprises" other components, unless there is a clear contrary description, it should not be limited to only consisting of the corresponding components, but should be understood as also including other components.

[0061] Figure 4 It is a perspective view showing the structure of the countercurrent total heat exchanger 100 manufactured by the manufacturing method of the countercurrent total heat exchanger of the present invention. In the countercurrent total heat exchanger 100 manufactured by the manufacturing method of the countercurrent total heat exchanger of the present invention, a plurality of external gas supply parts 110 and a plurality of internal gas discharge parts 120 are alternately arranged with each other in the height direction, and a lining 130 for transferring heat and moisture is arranged between the adjacent external gas supply part 110 and the internal gas discharge part 120.

[0062] The countercurrent total heat exchanger 100 of the present invention is formed in a columnar shape with a hexagonal cross-section as a whole. The countercurrent total heat exchanger 100 exchanges heat during the process of moving indoor air B and outdoor air A in a countercurrent manner, so its heat exchange efficiency is relatively high.

[0063] In addition, since the areas where the external gas supply part 110, the internal gas discharge part 120, and the lining are in contact with each other are formed of paper, the heat exchange and moisture transfer efficiency can be improved. And since resin tubes formed of resin are pasted on both sides, it has the advantages of simple manufacturing and low cost.

[0064] Figure 5 and Figure 6 are perspective views showing the structures of the external gas supply part 110 and the internal gas discharge part 120 respectively. As Figure 5 shown, the external gas supply part 110 includes: an external gas guiding corrugated paper 111, formed of a paper material, for guiding the outdoor air A; external gas side walls 113, vertically joined to both sides of the external gas guiding corrugated paper 111, for preventing leakage to the outside when the outdoor air A moves; an external gas inflow resin tube 115, formed of a resin material, communicatively joined to one side of the external gas guiding corrugated paper 111, through which the outdoor air A can flow in; and an external gas outflow resin tube 117, formed of a resin material, communicatively joined to the other side of the external gas guiding corrugated paper 111, for discharging the outdoor air A to the inside.

[0065] The external gas guiding corrugated paper 111, as Figure 5 shown in the enlarged cross-sectional view of the upper part, repeatedly forms peaks 111a and valleys 111b. A plurality of external gas guiding flow paths 111c for the outdoor air A to move are horizontally formed between the peaks 111a and valleys 111b of the external gas guiding corrugated paper 111.

[0066] The external gas side walls 113 are vertically joined to both sides of the external gas guiding corrugated paper 111. The external gas side walls 113, as Figure 4 and Figure 7As shown in (b) of , when a plurality of external gas supply units 110 and internal gas discharge units 120 are stacked vertically, they are arranged along the vertical direction in the edge regions of the four sides where the external gas inflow holes 115e and the external gas outflow holes 117e are not formed. Therefore, it is possible to prevent the outdoor air A flowing through the external gas guiding flow path 111c from leaking to the outside.

[0067] The external gas side wall 113 is adhesively attached to the outside of the external gas guiding corrugated paper 111 in a manner perpendicular to the inner liner 130.

[0068] The external gas guiding corrugated paper 111, as Figure 8 shown, forms peaks b and valleys a on the surface by means of a roll-to-roll process during the movement of the first paper P1 between a pair of rollers 210, 210a. Therefore, it is difficult to integrally form the vertically formed external gas side wall 113.

[0069] Therefore, the external gas side wall 113 is joined by pasting papers formed perpendicular to both sides of the external gas guiding corrugated paper 111. The height of the external gas side wall 113 corresponds to the heights of the peaks b and valleys a, and is formed by pasting papers of the same thickness to the upper side of the inner liner 130 using an adhesive.

[0070] The external gas inflow resin tube 115 and the external gas outflow resin tube 117 are respectively joined to both sides of the external gas guiding corrugated paper 111. The external gas inflow resin tube 115 and the external gas outflow resin tube 117 are formed in the shape of a right triangle and are arranged in such a way that one side of each contacts the external gas guiding corrugated paper 111.

[0071] The external gas inflow resin tube 115 is formed of a resin material. The external gas inflow resin tube 115 is formed by cutting a resin plate 300 (see Figure 11 ) made of a synthetic resin material in such a way that one side is connected and the other side is closed. As shown in the enlarged cross-sectional view of the upper part, the external gas inflow resin tube 115 includes: a bottom plate 115a and an upper plate 115b, which are formed in parallel; and a plurality of partition walls 115c, which are formed vertically at a predetermined interval between the bottom plate 115a and the upper plate 115b. Figure 5 The external gas inflow resin tube 115 forms a plurality of external gas inflow channels 115d between the bottom plate 115a and the upper plate 115b by means of the plurality of partition walls 115c.

[0072]

[0073] ​Among them, the external gas in the triangular shape is arranged to flow into one side of the resin tube 115 in contact with the external gas guiding corrugated paper 111, and an external gas inflow hole 115e through which the outdoor gas A can flow into the external gas inflow passage 115d is formed on the other side. The remaining one side is equipped in a manner of being closed by the partition wall 115c.

[0074] At this time, a plurality of external gas inflow passages 115d are formed by bending a predetermined angle on one side of the horizontally formed external gas guiding corrugated paper 111.

[0075] The external gas outflow resin tube 117 is formed in such a way that all the remaining components are the same as those of the external gas inflow resin tube 115 except for the inclination angle of the external gas outflow passage. An external gas outflow hole 117e is formed at the end of the external gas outflow passage.

[0076] After the outdoor air A flows into the external gas inflow hole 115e of the external gas inflow resin tube 115, it then flows into the external gas inflow passage 115d, and after horizontally moving a predetermined distance along the external gas guiding flow path 111c of the external gas guiding corrugated paper 111, it is supplied to the interior through the external gas outflow hole 117e of the external gas outflow resin tube 117.

[0077] The internal gas discharge part 120 is alternately arranged on the upper and lower sides of the external gas supply part 110 for discharging the indoor air B to the outside. The internal gas discharge part 120 includes: an internal gas guiding corrugated paper 121; internal gas side walls 123 arranged perpendicular to both sides of the internal gas guiding corrugated paper 121; an internal gas inflow resin tube 125 for flowing the indoor air B into the internal gas guiding corrugated paper 121; and an internal gas outflow resin tube 127 for discharging the indoor air B in the internal gas guiding corrugated paper 121 to the outside.

[0078] The internal gas discharge part 120 has the same structure as the external gas supply part 110, but the inclination angles of the internal gas inflow resin tube 125 and the internal gas outflow resin tube 127 are formed in a direction opposite to that of the external gas outflow resin tube 117 and the external gas inflow resin tube 115 arranged on the upper part.

[0079] After the indoor air B flows into the internal gas inflow hole 125e of the internal gas inflow resin tube 125, it then moves along the internal gas guiding corrugated paper 121 and is then discharged to the internal gas outflow resin tube 127.

[0080] Among them, the internal gas discharge part 120 and the external gas supply part 110 of the present invention are as Figure 4As shown, it is formed with a sufficient length to enable the indoor air B and the outdoor air A to fully contact and perform heat exchange in the internal gas guiding corrugated paper 121 and the external gas guiding corrugated paper 111.

[0081] The inner liner 130 is disposed between a plurality of externally disposed gas supply portions 110 and internally disposed gas discharge portions 120 which are alternately arranged up and down, so that heat and moisture can be transferred therebetween. The inner liner 130 of the present invention is formed of the same paper as the external gas guiding corrugated paper 111 and the internal gas guiding corrugated paper 121. Thereby, the heat transfer efficiency and the moisture transfer efficiency can be improved.

[0082] That is, as shown in (a) of Figure 7 The inner liner 130 is disposed between the external gas guiding corrugated paper 111 and the internal gas guiding corrugated paper 121, so as to receive heat from the internal gas guiding corrugated paper 121 and supply it to the external gas guiding corrugated paper 111. In addition, the inner liner 130 can transfer moisture moving along the external gas guiding corrugated paper 111 and the internal gas guiding corrugated paper 121 to each other.

[0083] The inner liner 130, as shown in Figure 13 includes: a corrugated paper bonding surface 131, cut into a hexagonal shape, for bonding the external gas guiding corrugated paper 111 or the internal gas guiding corrugated paper 121 at the central portion; and a resin tube bonding surface 133, formed in a triangular shape on both sides of the corrugated paper bonding surface 131, for bonding the inflow resin tubes 115, 125 and the outflow resin tubes 117, 127.

[0084] Figures 8 to 13 is an exemplary diagram schematically illustrating the manufacturing process of the counterflow total heat exchanger 100 of the present invention.

[0085] The counterflow total heat exchanger 100 of the present invention manufactures the external gas guiding corrugated paper 111, the internal gas guiding corrugated paper 121 and the inner liner 130 using paper, and manufactures the external gas inflow resin tubes 115, the external gas outflow resin tubes 117, the internal gas inflow resin tubes 125 and the internal gas outflow resin tubes 127 using resin plates 300 respectively. In addition, the external gas supply portion 110 is manufactured by pasting the external gas guiding corrugated paper 111, the external gas inflow resin tubes 115 and the external gas outflow resin tubes 117 on the inner liner 130 manufactured in the above-described manner, and the internal gas discharge portion 120 is manufactured by pasting the internal gas inflow resin tubes 125 and the internal gas outflow resin tubes 127 on the internal gas guiding corrugated paper 121.

[0086] In addition, the counterflow total heat exchanger 100 is completed by alternately laminating the manufactured external gas supply unit 110 and the internal gas discharge unit 120 with each other.

[0087] Figure 8 It is an exemplary diagram illustrating the process of manufacturing the external gas guiding corrugated paper 111 and the internal gas guiding corrugated paper 121 using the papers P1 and P2.

[0088] As shown in the figure, the first paper P1 with the first width W1 is supplied between a pair of rollers 210 and 210a. Among them, the first width W1 is, as Figure 5 shown, the width of the external gas guiding corrugated paper 111. On the surfaces of the pair of rollers 210 and 210a, a plurality of protrusions 211 are formed along the outer circumferential surface.

[0089] During the process of passing between the pair of rollers 210 and 210a, the first paper P1 is processed into a hollow plate T having peaks a and valleys b formed in a single side surface form on the surface.

[0090] The hollow plate T is supplied to the upper part of the second paper P2. The second paper P2 is formed with a second width W2 corresponding to the overall width of the lining 130. The second paper P2 is supplied to the lower part of the second roller 210a while being unwound from the second paper supply roller 220.

[0091] As Figure 9 shown in (a) of, the hollow plate T is supplied to the middle area of the second paper P2, and the hollow plate T is to be pasted onto the second paper P2.

[0092] As Figure 8 and Figure 9 shown in (b) of, the second paper P2 pasted with the hollow plate T is processed into a shape corresponding to the lining 130 through the first cutting process. The second paper P2 is respectively cut into a length l corresponding to the lining 130. Thereby, the hollow plate T will also be cut into a size corresponding to the external gas guiding corrugated paper 111 and the internal gas guiding corrugated paper 121.

[0093] In addition, as Figure 9 shown in (c) of, resin tubes 115, 117, 125, and 127 are pasted on the upper side surface of the second paper P2.

[0094] In addition, as Figure 10 shown in (a) of, by cutting the second paper P2 protruding outside the resin tubes 115, 117, 125, and 127, it is processed into a shape corresponding to the resin tube bonding surface 133. Thereby, the lining 130 with the external gas guiding corrugated paper 111 or the internal gas guiding corrugated paper 121 bonded to the upper side surface will be completed.

[0095] In addition,Figure 11 It is a perspective view showing the constitution of the resin plate 300. The resin plate 300 is a plate-shaped body formed of a synthetic resin material. The resin plate 300 is preferably formed of polypropylene, a vertical wall 330 is formed between the upper side surface 310 and the lower side surface 320, and an air movement passage 340 is formed in a straight line along the length direction inside. The resin plate 300 can be waterproof and is widely applicable to various fields because of its advantages of durability and strong impact resistance.

[0096] In the present invention, by cutting a known resin plate 200 in the manner as Figure 12 shown, it is processed into an external gas inflow resin tube 115 and an external gas outflow resin tube 117, or an internal gas inflow resin tube 125 and an internal gas outflow resin tube 127.

[0097] The resin tubes 115, 117, 125, 127 can be cut into a shape corresponding to the resin tube joint surface 133 of the inner liner 130, or as Figure 9 and Figure 10 shown, can also be cut and processed into a < shape.

[0098] At this time, the resin tubes 115, 117, 125, 127 can be cut at a right angle to the resin plate 300 so as to form a shape with one side surface communicating and the other side surface closed. By cutting in the manner as described above, a resin tube in the form of a right-angled triangle with one side closed can be conveniently processed.

[0099] The resin tubes 115, 117, 125, 127 processed in the manner as described above, as Figure 13 shown, will be pasted onto the inner liner 130. The resin tubes 115, 117, 125, 127 are pasted onto both resin tube joint surfaces 130 of the inner liner 130 with the external gas guiding corrugated paper 111 or the internal gas guiding corrugated paper 121 joined to the upper side surface by an adhesive.

[0100] At this time, it can be divided into an external gas supply part 110 and an internal gas discharge part 120 according to the directions of the resin tubes 115, 117, 125, 127 pasted onto the resin tube joint surface 133 of the inner liner 130. In the case where the resin tubes 115, 117, 125, 127 are cut into a < shape, the resin tubes 115, 117, 125, 127 will be separated from the resin tube joint surface 133, but can be divided into an external gas supply part 110 and an internal gas discharge part 120 according to the directions of the resin tubes 115, 117, 125, 127.

[0101] In the state where a plurality of external gas supply parts 110 and internal gas discharge parts 120 are pasted onto the inner liner 130, in the manner asFigure 10 They are alternately pasted in the height direction in the manner shown in (b) of

[0102] In addition, as Figure 10 shown in (c) of

[0103] The method for manufacturing the counterflow total heat exchanger of the present invention as described above can manufacture general paper into external gas guiding corrugated paper, internal gas guiding corrugated paper, and a lining using an existing roll-to-roll device.

[0104] In addition, the external gas supply part and the internal gas discharge part can be conveniently manufactured by cutting a commercially available resin plate into a resin tube and pasting it into the lining. In addition, the external gas supply part and the internal gas discharge part manufactured in the manner described above can be alternately stacked with each other.

[0105] Thereby, the manufacture of the counterflow total heat exchanger can be completed only by using an existing roll-to-roll device, a cutting device, and a pasting device without the need for a separate special device, thus saving manufacturing costs.

[0106] In addition, since the lining, the external gas guiding corrugated paper, and the internal gas guiding corrugated paper of the counterflow total heat exchanger manufactured in the manner described above are formed of the same paper, it also has the advantages of high heat transfer efficiency and high moisture transfer efficiency.
