Description

Heat exchange elements, total heat exchange core assemblies, humidification cores and air handling equipment

[0001] The present invention relates to heat exchange elements, total heat exchange core assemblies including heat exchange elements, humidification cores including heat exchange elements, and air handling equipment including total heat exchange core assemblies or humidification cores.

[0002] Conventionally, there is a heat exchange element including a partition member and a spacer retaining member. The partition member is sheet-shaped, and the spacer retaining member is integrally formed on the partition member to hold the partition member at a predetermined interval. It also has spacer ribs and deflection suppression ribs located on both sides of the partition member in the thickness direction.

[0003] However, in the heat exchange elements mentioned above, the spacer holding member has spacer ribs and deflection suppression ribs located on both sides of the thickness direction of the spacer member, which makes the structure complex and easily affects the heat exchange performance of the heat exchange element.

[0004] The present invention was made in view of the above-mentioned problems, and aims to provide a heat exchange element, a total heat exchange core assembly including the heat exchange element, a humidification core including the heat exchange element, and an air handling device including a total heat exchange core assembly or a humidification core, which helps to simplify the structure of the heat exchange element, reduce the manufacturing difficulty of the heat exchange element, and ensure the heat exchange performance of the heat exchange element.

[0005] To achieve the above objectives, the present invention provides a heat exchange element, including a heat exchange plate and a frame, wherein the frame is disposed on one side of the heat exchange plate in the thickness direction and includes a partition rib, the partition rib extending along a first direction and separating adjacent fluid channels, the frame further includes a reinforcing rib, the reinforcing rib extending along a second direction intersecting the first direction and connected to the partition rib, wherein the thickness of the reinforcing rib in the thickness direction of the heat exchange plate is less than the thickness of the partition rib.

[0006] According to the heat exchange element of the present invention, the frame is disposed on one side of the heat exchange plate in the thickness direction and includes a partition rib extending along a first direction and separating adjacent fluid channels. Therefore, compared with forming the frame having portions located on both sides of the heat exchange plate in the thickness direction, it helps to simplify the structure of the heat exchange element, simplify the manufacturing process, and thereby improve the yield. Furthermore, the frame also includes a reinforcing rib extending along a second direction intersecting the first direction and connected to the partition rib. In the thickness direction of the heat exchange plate, the thickness of the reinforcing rib is less than the thickness of the partition rib. Therefore, while suppressing the resistance of the reinforcing rib to the fluid in the fluid channel, it can improve the support strength of the frame for the heat exchange plate and suppress the deformation of the heat exchange plate, ensuring unobstructed fluid channels and thus ensuring the heat exchange performance of the heat exchange element.

[0007] Furthermore, in the heat exchange element of the present invention, it is preferable that the thickness of the reinforcing rib is less than or equal to half the thickness of the separating rib.

[0008] According to the heat exchange element of the present invention, the thickness of the reinforcing rib is less than or equal to half the thickness of the partition rib. Therefore, the resistance caused by the reinforcing rib to the fluid in the fluid channel can be better suppressed, thereby improving the heat exchange performance of the heat exchange element.

[0009] Furthermore, in the heat exchange element of the present invention, it is preferable that the size of the reinforcing rib in the first direction is larger than the size of the separating rib in the second direction.

[0010] According to the heat exchange element of the present invention, the size of the reinforcing rib in the first direction is larger than that of the partition rib in the second direction. Therefore, when the frame is formed by injection molding, it is convenient to inject glue. At the same time, the support strength of the frame for the heat exchange plate can be further improved.

[0011] Furthermore, in the heat exchange element of the present invention, preferably, one or multiple reinforcing ribs are provided in the first direction at intervals.

[0012] According to the heat exchange element of the present invention, when multiple reinforcing ribs are spaced apart in the first direction, the support strength of the frame for the heat exchange plate can be further improved, and the damage to the heat exchange plate can be reduced.

[0013] Furthermore, in the heat exchange element of the present invention, preferably, a plurality of the partition ribs are spaced apart in the second direction, and the reinforcing ribs include at least one of a first reinforcing rib and a second reinforcing rib. The first reinforcing rib is continuously formed in the second direction and connects adjacent partition ribs to each other, and the second reinforcing rib is intermittently formed in the second direction and connects adjacent partition ribs to each other.

[0014] According to the heat exchange element of the present invention, a plurality of partition ribs are spaced apart in the second direction, and the reinforcing ribs include at least one of a first reinforcing rib and a second reinforcing rib. The first reinforcing rib is continuously formed in the second direction and connects adjacent partition ribs to each other. The second reinforcing rib is discontinuously formed in the second direction and connects adjacent partition ribs to each other. Therefore, the support strength of the frame for the heat exchange plate can be improved. In particular, when the second reinforcing rib is included, the resistance caused by the reinforcing rib to the fluid in the fluid channel can also be suppressed.

[0015] Furthermore, in the heat exchange element of the present invention, it is preferred that the frame is injection molded and that gate marks are formed on the reinforcing ribs.

[0016] According to the heat exchange element of the present invention, the frame is injection molded and has gate marks formed on the reinforcing ribs. Therefore, when the heat exchange element is stacked on another heat exchange element, the gate marks on the reinforcing ribs of the heat exchange element can be prevented from contacting the heat exchange plates of the other heat exchange element, thus avoiding damage to the heat exchange plates of the other heat exchange element.

[0017] Furthermore, in the heat exchange element of the present invention, it is preferable that when the width of the reinforcing rib in the first direction is d, the following relationship is satisfied: d≤5mm.

[0018] According to the heat exchange element of the present invention, when the width of the reinforcing rib in the first direction is d, the following relationship is satisfied: d≤5mm. Therefore, it is possible to avoid the reinforcing rib being too thick, which would result in large obstruction of the fluid and high pressure loss.

[0019] Furthermore, in the heat exchange element of the present invention, it is preferable that a plurality of the partition ribs are spaced apart in the second direction, and when the spacing of the partition ribs is A, the following relationship is satisfied: 5mm≤A≤15mm.

[0020] According to the heat exchange element of the present invention, a plurality of partition ribs are provided at intervals in the second direction. When the spacing of the partition ribs is A, the following relationship is satisfied: 5mm≤A≤15mm. Therefore, it can avoid the partition ribs being too dense, which would reduce the overall fluid channel. On the other hand, it can avoid the partition ribs being too sparse, which would result in insufficient support strength for the heat exchange plate.

[0021] Furthermore, in the heat exchange element of the present invention, the frame preferably includes a frame, the partition rib and the reinforcing rib are disposed on the inner side of the frame, the frame has a pair of opposite sides in the second direction, and at least one of the pair of sides is formed with an anti-overflow adhesive structure to prevent adhesive from overflowing toward the inner side of the frame.

[0022] According to the heat exchange element of the present invention, the frame includes a frame, a partition rib and a reinforcing rib disposed on the inner side of the frame. The frame has a pair of opposite sides in a second direction. At least one of the pair of sides is formed with an anti-overflow adhesive structure to prevent adhesive from overflowing toward the inner side of the frame. Therefore, when the heat exchange elements are stacked, even if adhesive is applied to the side of another heat exchange element that is inserted into the slot of one heat exchange element, the adhesive leakage to the inner side of the frame and blockage of the fluid channel can be prevented.

[0023] Furthermore, in the heat exchange element of the present invention, it is preferable to further include another frame disposed on the other side of the thickness direction of the heat exchange plate, the frame including a partition rib extending in a direction intersecting the first direction and separating adjacent fluid channels.

[0024] According to the present invention, in addition to the frame disposed on one side of the heat exchange plate in the thickness direction, another frame disposed on the other side of the heat exchange plate in the thickness direction is separately formed from the above-mentioned frame. The frame includes a partition rib extending in a direction intersecting the first direction and separating adjacent fluid channels, thereby helping to further improve the support strength of the frame for the heat exchange plate.

[0025] Furthermore, in order to achieve the above objectives, the present invention provides a total heat exchange core assembly, including alternatingly stacked first heat exchange elements and second heat exchange elements, and forming fluid channels that are connected in directions that intersect each other in adjacent layers, wherein at least one of the first heat exchange elements and the second heat exchange elements uses the aforementioned heat exchange elements, and the fluid channels are formed by a plurality of the aforementioned partition ribs.

[0026] Furthermore, in order to achieve the above objectives, the present invention provides a wet core comprising alternating layers of a first heat exchange element and a second heat exchange element, wherein one of the first heat exchange element and the second heat exchange element uses any of the aforementioned heat exchange elements and forms an airflow channel through a plurality of the aforementioned partition ribs, and the other of the first heat exchange element and the second heat exchange element uses any of the aforementioned heat exchange elements and forms a water flow channel through a plurality of the aforementioned partition ribs, wherein the airflow channel and the water flow channel extend in adjacent layers in directions intersecting each other.

[0027] Furthermore, in order to achieve the above objectives, the present invention provides an air handling device, which includes the above-mentioned total heat exchange core assembly, and the air handling device is one of a total heat exchanger with a total heat exchange core assembly, a fresh air unit, and an air conditioning indoor unit; or, it includes the above-mentioned humidifying core, and the air handling device is a humidifying device with a humidifying core.

[0028] (Invention effect)

[0029] According to the present invention, the frame is disposed on one side of the heat exchange plate in the thickness direction and includes a partition rib extending along a first direction and separating adjacent fluid channels. Therefore, compared with forming the frame with portions located on both sides of the heat exchange plate in the thickness direction, it helps to simplify the structure of the heat exchange element, simplify the manufacturing process, and thereby improve the yield. Furthermore, the frame also includes a reinforcing rib extending along a second direction intersecting the first direction and connected to the partition rib. In the thickness direction of the heat exchange plate, the thickness of the reinforcing rib is less than the thickness of the partition rib. Therefore, while suppressing the resistance of the reinforcing rib to the fluid in the fluid channel, it can improve the support strength of the frame for the heat exchange plate and suppress the deformation of the heat exchange plate, ensuring unobstructed fluid channels and thus ensuring the heat exchange performance of the heat exchange element.

[0040] Figure 11 is a perspective view schematically showing a modified example of the total heat exchange core assembly of the present invention.

[0041] The total heat exchange core assembly of the present invention will now be described with reference to Figures 1 to 10.

[0042] For ease of explanation, the three mutually orthogonal directions are designated as X, Y, and Z. One side of the X direction is designated as X1, and the other side as X2. One side of the Y direction is designated as Y1, and the other side as Y2. One side of the Z direction is designated as Z1, and the other side as Z2.

[0043] As shown in Figure 1, the total heat exchange core assembly 10 can be applied to the air handling equipment 1.

[0044] Here, as shown in Figure 1, the air handling unit 1 is a total heat exchanger, including a housing KT. The housing KT is made of, for example, a metal material and has a top wall, a bottom wall spaced apart from the top wall, and side walls extending from the periphery of the top wall to the periphery of the bottom wall (the top wall and bottom wall can be formed separately from the side walls, or they can be formed integrally with the side walls). Furthermore, a fresh air inlet JF, an exhaust air inlet PF, a return air inlet HF, and a supply air inlet SF are provided on the side walls of the housing KT. Inside the housing KT, an air supply path is formed from the fresh air inlet JF to the supply air inlet SF; and an exhaust air path is formed from the return air inlet HF to the exhaust air inlet PF. An internal circulation path from the return air inlet HF to the supply air inlet SF can also be formed.

[0045] Furthermore, as shown in Figure 1, the total heat exchange core assembly 10 is disposed within the housing KT. The housing KT includes: a housing body with a maintenance opening (in the illustrated example, the maintenance opening is located on the bottom wall of the housing body); and a maintenance cover capable of opening and closing the maintenance opening (e.g., connected to the housing body via a connecting rope, or rotatably connected to the housing body via a hinge). Preferably, a locking mechanism is provided on the housing body to lock or unlock the total heat exchange core assembly 10. Alternatively, the maintenance cover may protrude from the outer surface of the housing body when the maintenance opening is closed, or the housing body may have a recess around the maintenance opening, such that the outer surface of the maintenance cover is flush with the outer surface of the housing body when the maintenance opening is closed. Preferably, a sealing material is affixed to the back of the maintenance cover.

[0046] In addition, the total heat exchange core assembly 10 has: a first fluid channel forming part of the air supply path; and a second fluid channel forming part of the exhaust path, and the fluid flowing through the first fluid channel can exchange heat with the fluid flowing through the second fluid channel.

[0047] (Structure of the total heat exchange core assembly)

[0048] As shown in Figures 2 to 4, the total heat exchange core assembly 10 is block-shaped and includes alternating layers of first heat exchange elements 11 and second heat exchange elements 12, and forms fluid channels that are connected in directions that intersect each other in adjacent layers.

[0049] Here, as shown in Figures 2 and 3, the total heat exchange core assembly 10 also includes a top plate 13, a bottom plate (not shown), and side columns 14. The side columns 14 connect the top plate 13 and the bottom plate. For example, the side columns 14 pass through the top plate 13, the bottom plate, and the edges of the first heat exchange element 11 and the second heat exchange element 12 sandwiched between the top plate 13 and the bottom plate, and fix them in place.

[0050] (Structure of the first heat exchange element)

[0051] As shown in Figure 5, the first heat exchange element 11 includes a heat exchange plate 111 and a frame 112. The frame 112 is disposed on one side of the thickness direction (Z direction in the illustrated example) of the heat exchange plate 111 (Z1 direction side in the illustrated example) and includes a partition rib 1121. The partition rib 1121 extends along a first direction (X direction in the illustrated example) and separates adjacent fluid channels. The frame 112 also includes a reinforcing rib 1122. The reinforcing rib 1122 extends along a second direction (Y direction in the illustrated example) that intersects the first direction and is connected to the partition rib 1121. In the thickness direction of the heat exchange plate 111, the thickness of the reinforcing rib 1122 is less than the thickness of the partition rib 1121.

[0052] Here, the heat exchange plate 111 can be a thin film (e.g., PP film) or paper with heat exchange and humidification functions, or it can be metal. Specifically, as shown in FIG6, the heat exchange plate 111 includes a substrate layer 1111 and a functional layer 1112, with the substrate layer 1111 positioned on one side of the thickness direction of the heat exchange plate 111 (in the illustrated example, the Z1 direction side) compared to the functional layer 1112. Furthermore, the substrate layer 1111 is formed of at least one of a metallic material, a plastic material, and a fibrous material. The metallic material can be, for example, aluminum foil; the plastic material can be, for example, polypropylene, polyethylene; and the fibrous material can be, for example, paper. Alternatively, other materials can be used to form the substrate layer, such as polymer materials, molecular sieves, graphene, zeolite, modified materials, and composite chemical materials. On the other hand, the functional layer 1112 includes a hygroscopic material, allowing water molecules to be adsorbed onto the functional layer 1112. Furthermore, the functional layer 1112 is configured to block substances such as CO2 molecules, viruses, and bacteria. Accordingly, a moisture-permeable structure is formed on the substrate layer 1111, which allows water molecules adsorbed on the functional layer 1112 to pass through the substrate layer 1111. The moisture-permeable structure is, for example, a moisture-permeable pore formed on the substrate layer 1111. The functional layer 1112 and the substrate layer 1111, as described above, work together to allow the heat exchange plate 111 to block harmful components such as CO2 molecules, viruses, and bacteria in the air, while simultaneously allowing moisture and heat to pass through, thereby effectively treating the air supplied to the room.

[0053] Furthermore, as shown in Figures 5 and 6, in the frame 112, the partition ribs 1121 and reinforcing ribs 1122 are respectively attached to the surface of the substrate layer 1111 of the heat exchange plate 111 (in the illustrated example, the Z1 direction side) (that is, the partition ribs 1121 and reinforcing ribs 1122 can support the heat exchange plate 111 from the substrate layer 1111 side). The frame 112 is integrally formed on the heat exchange plate 111, for example, by injection molding, and the material of the frame 112 can be plastic (e.g., polypropylene, polystyrene, acrylonitrile-styrene-butadiene copolymer). The frame 112 includes a frame 1120, with the partition ribs 1121 and reinforcing ribs 1122 disposed inside the frame 1120. The two ends of the partition ribs 1121 are connected to the frame 1120, and the two ends of the reinforcing ribs 1122 are also connected to the frame 1120. Specifically, the border 1120 is rectangular in shape and includes: a pair of sides 1120a and 1120b, which are spaced apart and opposite each other in a first direction (X direction in the illustrated example) and extend along a second direction (Y direction in the illustrated example); and a pair of sides 1120c and 1120d, which are spaced apart and opposite each other in the second direction, extend along the first direction, and connect the two ends of the pair of sides 1120a and 1120b. Furthermore, as shown in Figure 7, edges 1120a and 1120b are respectively provided with through holes TH1 for the side pillars 14 to pass through, and edges 1120c and 1120d are respectively provided with through holes TH2 for the side pillars 14 to pass through. Multiple through holes TH1 are spaced apart in the second direction (in the illustrated example, also the length direction of edges 1120a and 1120b). When viewed along the first direction (in the illustrated example, the X direction), these multiple through holes TH1 overlap with the partition rib 1121. Multiple through holes TH2 are spaced apart in the first direction (in the illustrated example, also the length direction of edges 1120c and 1120d). When viewed along the second direction (in the illustrated example, the Y direction), these multiple through holes TH2 overlap with the reinforcing rib 1122. Furthermore, the frame 1120 of the first heat exchange element 11 can engage with the frame 1220 of the second heat exchange element 12, and an anti-overflow adhesive structure is formed on the inner edge of the frame 1120. Specifically, as shown in Figures 4 and 8, a groove C1 is provided on the other side of the edges 1120c and 1120d in the thickness direction of the heat exchange plate 111 (in the example shown, the Z2 direction side) for the edges 1220a and 1220b of the second heat exchange element 12 to be inserted. A slot C2 is provided on one side of the edges 1120c and 1120d in the thickness direction of the heat exchange plate 111 (in the example shown, the Z1 direction side). The sidewall of the slot C2 on the side of the reinforcing rib 1122 is a convex edge that protrudes from the side of the reinforcing rib 1122 in the thickness direction of the heat exchange plate 111 (in the example shown, the Z1 direction side), forming an anti-overflow adhesive structure.Furthermore, the slot C2 is also for the following sides 1220a and 1220b of the second heat exchange element 12 to be inserted, and is closer to the inside of the frame 112 than the groove C1.

[0054] Furthermore, as shown in Figure 5, multiple partition ribs 1121 are spaced apart in the second direction (in the illustrated example, they are spaced equally apart, but not limited to this). Also, the two ends of each partition rib 1121 are connected to a pair of edges 1120a and 1120b, respectively. Furthermore, in the thickness direction of the heat exchange plate 111 (the Z direction in the illustrated example), the thickness of the partition rib 1121 is the same as the height of the fluid channel.

[0055] Furthermore, as shown in Figure 5, multiple reinforcing ribs 1122 are spaced apart in a first direction (the X direction in the illustrated example; they are spaced equally apart in the illustrated example, but are not limited thereto). At least a portion of the reinforcing ribs 1122 have their two ends connected to a pair of edges 1120c and 1120d, respectively. Additionally, gate marks are formed on at least a portion of the reinforcing ribs 1122 (for example, formed at the middle portion along the length of the reinforcing rib 1122, and formed on the surface of the reinforcing rib 1122 on the Z1 direction side).

[0056] Furthermore, as shown in Figure 5, the reinforcing rib 1122 includes a first reinforcing rib 1122a and a second reinforcing rib 1122b. The first reinforcing rib 1122a is continuously formed in the second direction (the Y direction in the illustrated example) and connects adjacent separating ribs 1121 to each other. The second reinforcing rib 1122b is discontinuously formed in the second direction (the Y direction in the illustrated example) and connects adjacent separating ribs 1121 to each other. (In the illustrated example, the second reinforcing rib 1122b includes multiple segments located on a straight line extending along the second direction and spaced apart from each other, of which the segment at the center in the second direction is...) The central section in the second direction is longer than the sections on both sides of the second direction, and the number of partition ribs 1121 connected to it is greater than the number of partition ribs 1121 connected to it on both sides of the second direction. Specifically, in the sections on both sides of the second direction, some connect two adjacent partition ribs 1121 to each other, some connect three adjacent partition ribs 1121 to each other, and some connect five adjacent partition ribs 1121 to each other; in contrast, the central section in the second direction connects nine adjacent partition ribs 1121 to each other. This helps to suppress deformation of the easily deformable central portion of the heat exchange plate 111 in the second direction. Furthermore, the first reinforcing rib 1122a connects the middle portions of a pair of sides 1120c and 1120d along their length direction, and the second reinforcing rib 1122b is provided between the pair of sides 1120a and 1120b, spaced apart from the first reinforcing rib 1122a (in the illustrated example, the pair of second reinforcing ribs 1122b are symmetrically arranged with respect to the first reinforcing rib 1122a, but it is not limited to this; the pair of second reinforcing ribs 1122b can also be arranged asymmetrically with respect to the first reinforcing rib 1122a, for example, the first reinforcing rib 1122a can be arranged at a position offset from the middle of the length direction of the sides 1120c and 1120d).

[0057] Furthermore, the thickness of the reinforcing rib 1122 is preferably less than or equal to half the thickness of the partition rib 1121. Also, the dimension of the reinforcing rib 1122 in the first direction is preferably larger than the dimension of the partition rib 1121 in the second direction. Furthermore, when the width of the reinforcing rib 1122 in the first direction is d, it is preferably satisfied that d ≤ 5 mm. Furthermore, when the spacing of the partition ribs 1121 is A, it is preferably satisfied that 5 mm ≤ A ≤ 15 mm.

[0058] (Structure of the second heat exchange element)

[0059] As shown in Figure 9, the second heat exchange element 12 includes a heat exchange plate 121 and a frame 122. The frame 122 is located on one side of the thickness direction (Z direction in the illustrated example) of the heat exchange plate 121 (Z1 direction side in the illustrated example) and includes a partition rib 1221. The partition rib 1221 extends along a third direction (Y direction in the illustrated example) and separates adjacent fluid channels. The frame 122 also includes a reinforcing rib 1222. The reinforcing rib 1222 extends along a fourth direction (X direction in the illustrated example) that intersects with the third direction and is connected to the partition rib 1221. In the thickness direction of the heat exchange plate 121, the thickness of the reinforcing rib 1222 is less than the thickness of the partition rib 1221.

[0060] Furthermore, similar to the first heat exchange element 11, the heat exchange plate 121 of the second heat exchange element 12 can also be a thin film (e.g., PP film) or paper with heat exchange and humidification functions, or it can be metal. Specifically, the heat exchange plate 121 of the second heat exchange element 12 includes a substrate layer and a functional layer, with the substrate layer positioned on one side of the heat exchange plate 121 in the thickness direction compared to the functional layer. The substrate layer is formed from at least one of a metallic material, a plastic material, and a fibrous material. The metallic material can be, for example, aluminum foil; the plastic material can be, for example, polypropylene or polyethylene; and the fibrous material can be, for example, paper. Alternatively, other materials can be used to form the substrate layer, such as polymers, molecular sieves, graphene, zeolites, modified materials, and composite chemical materials. On the other hand, the functional layer includes a hygroscopic material, allowing water molecules to be adsorbed onto the functional layer. Furthermore, the functional layer is configured to block molecules such as CO2 molecules, viruses, and bacteria. Accordingly, a permeable structure is formed on the substrate layer, allowing water molecules adsorbed on the functional layer to pass through the substrate layer. The moisture-permeable structure is, for example, a moisture-permeable hole formed on the substrate layer. The functional layer and the substrate layer provided as described above work together to enable the heat exchange plate to block harmful components such as CO2 molecules, viruses and bacteria in the air, while allowing moisture and heat to pass through the heat exchange plate 121, thereby effectively treating the air supplied to the room.

[0061] Furthermore, in the frame 122, the partition ribs 1221 and the reinforcing ribs 1222 are respectively attached to the surface of the heat exchange plate 121 on one side of the substrate layer (in the illustrated example, the Z1 direction side) (that is, the partition ribs 1221 and the reinforcing ribs 1222 can support the heat exchange plate 121 from the substrate layer side). The frame 122 is integrally formed on the heat exchange plate 121 by injection molding, and the material of the frame 122 can be plastic (e.g., polypropylene, polystyrene, acrylonitrile-styrene-butadiene copolymer). The frame 122 includes a frame 1220, with the partition ribs 1221 and the reinforcing ribs 1222 disposed inside the frame 1220. The two ends of the partition ribs 1221 are connected to the frame 1220, and the two ends of the reinforcing ribs 1222 are also connected to the frame 1220. Specifically, the border 1220 is rectangular in shape and includes: a pair of sides 1220a and 1220b, which are spaced apart and opposite each other in a third direction (Y direction in the illustrated example) and extend along a fourth direction (X direction in the illustrated example); and a pair of sides 1220c and 1220d, which are spaced apart and opposite each other in the fourth direction, extend along a third direction, and connect the two ends of the pair of sides 1220a and 1220b. Furthermore, as shown in Figure 10, sides 1220a and 1220b are respectively provided with through holes TH3 for the side pillars 14 to pass through, and sides 1220c and 1220d are respectively provided with through holes TH4 for the side pillars 14 to pass through. Multiple through holes TH3 are provided at intervals in the fourth direction (in the example shown, this is also the length direction of sides 1220a and 1220b). When viewed along the third direction (in the example shown, this is the Y direction), these multiple through holes TH3 overlap with the partition rib 1221, and when viewed along the thickness direction of the heat exchange plate 121, they overlap with through holes TH2. Multiple through holes TH4 are provided at intervals in the third direction (in the example shown, this is also the length direction of sides 1220c and 1220d). When viewed along the fourth direction (in the example shown, this is the X direction), these multiple through holes TH4 overlap with the reinforcing rib 1222, and when viewed along the thickness direction of the heat exchange plate 121, they overlap with through holes TH1. Furthermore, the frame 1220 of the second heat exchange element 12 can engage with the frame 1120 of the first heat exchange element 11, and an anti-overflow adhesive structure is formed on the inner edge of the frame 1220. Specifically, on the other side of the edges 1220c and 1220d in the thickness direction of the heat exchange plate 121 (in the example shown, the Z2 direction side), a groove is provided for the edges 1120a and 1120b of the first heat exchange element 11 to be inserted. On the side of the edges 1220c and 1220d in the thickness direction of the heat exchange plate 121 (in the example shown, the Z1 direction side), a slot is provided. The sidewall of the slot on the side of the reinforcing rib 1222 is a convex edge that protrudes from the side of the reinforcing rib 1222 in the thickness direction of the heat exchange plate 121 (in the example shown, the Z1 direction side), thus forming an anti-overflow adhesive structure.Furthermore, the aforementioned slots are also for the edges 1120a and 1120b of the first heat exchange element 11 to be inserted into, and are closer to the inner side of the frame 122 than the aforementioned grooves.

[0062] Furthermore, as shown in Figure 9, multiple partition ribs 1221 are spaced apart in the fourth direction (the X direction in the illustrated example). (In the illustrated example, they are spaced equally apart, but this is not a limitation.) The two ends of each partition rib 1221 are connected to a pair of edges 1220a and 1220b, respectively. Moreover, in the thickness direction of the heat exchange plate 121 (the Z direction in the illustrated example), the thickness of the partition rib 1221 is the same as the height of the fluid channel.

[0063] Furthermore, as shown in Figure 9, multiple reinforcing ribs 1222 are spaced apart in a third direction (Y direction in the illustrated example) (they are spaced equally apart in the illustrated example, but are not limited to this). At least a portion of the reinforcing ribs 1222 have their two ends connected to a pair of edges 1220c and 1220d, respectively. Additionally, gate marks are formed on at least a portion of the reinforcing ribs 1222 (for example, formed at the middle portion in the length direction of the reinforcing rib 1222, and formed on the surface of the reinforcing rib 1222 in the Z1 direction).

[0064] Furthermore, as shown in Figure 9, the reinforcing rib 1222 includes a first reinforcing rib 1222a and a second reinforcing rib 1222b. The first reinforcing rib 1222a is continuously formed in the fourth direction (the X direction in the illustrated example) and connects adjacent partition ribs 1221 to each other. The second reinforcing rib 1222b is discontinuously formed in the fourth direction and connects adjacent partition ribs 1221 to each other. (In the illustrated example, the second reinforcing rib 1222b includes multiple segments spaced apart from each other along a straight line extending in the fourth direction. Among these segments, the segment in the center of the fourth direction is longer than the segments on both sides of the fourth direction, and the number of partition ribs 1221 connected to the segment in the center of the fourth direction is greater than the number of partition ribs 1221 connected to the segments on both sides of the fourth direction. Specifically, in the segments on both sides of the fourth direction, each segment connects two adjacent partition ribs 1221 to each other; in contrast, the segment in the center of the fourth direction connects three adjacent partition ribs 1221 to each other. This suppresses deformation of the easily deformable central portion of the heat exchange plate 121 in the fourth direction.) Furthermore, the first reinforcing rib 1222a connects the middle portions of a pair of sides 1220c and 1220d along their length direction, and the second reinforcing rib 1222b is provided between the pair of sides 1220a and 1220b, spaced apart from the first reinforcing rib 1222a (in the illustrated example, the pair of second reinforcing ribs 1222b are symmetrically arranged with respect to the first reinforcing rib 1222a, but it is not limited to this; the pair of second reinforcing ribs 1222b can also be arranged asymmetrically with respect to the first reinforcing rib 1222a, for example, the first reinforcing rib 1222a can be arranged at a position offset from the middle of the length direction of the sides 1220c and 1220d).

[0065] Furthermore, the thickness of the reinforcing rib 1222 is preferably less than or equal to half the thickness of the partition rib 1221. Also, the dimension of the reinforcing rib 1222 in the third direction is preferably larger than the dimension of the partition rib 1221 in the fourth direction. Furthermore, when the width of the reinforcing rib 1222 in the third direction is d, the following relationship is preferably satisfied: d ≤ 5 mm. Furthermore, when the spacing of the partition ribs 1221 is A, the following relationship is preferably satisfied: 5 mm ≤ A ≤ 15 mm.

[0066] (Main effects of this implementation method)

[0067] According to the total heat exchange core assembly 10 of this embodiment, in the first heat exchange element 11 (second heat exchange element 12), the frame 112 (frame 122) is disposed on one side of the heat exchange plate 111 (heat exchange plate 121) in the thickness direction and includes a partition rib 1121 (partition rib 1221). The partition rib 1121 (partition rib 1221) extends along a first direction (third direction) and separates adjacent fluid channels. Therefore, compared with forming the frame 112 (frame 122) to have portions located on both sides of the heat exchange plate 111 (heat exchange plate 121) in the thickness direction, it helps to simplify the structure of the first heat exchange element 11 (second heat exchange element 12), simplify the manufacturing process, and thus improve the yield. Furthermore, the frame 112 (frame 122) also includes a reinforcing rib 1. 122 (reinforcing rib 1222) extends along a second direction (fourth direction) intersecting the first direction (third direction) and connects with the partition rib 1121 (partition rib 1221). In the thickness direction of the heat exchange plate 111 (heat exchange plate 121), the thickness of the reinforcing rib 1122 (reinforcing rib 1222) is less than the thickness of the partition rib 1121 (partition rib 1221). Therefore, while suppressing the resistance of the reinforcing rib 1122 (reinforcing rib 1222) to the fluid in the fluid channel, it can improve the support strength of the frame 112 (frame 122) for the heat exchange plate 111 (heat exchange plate 121), ensuring the smooth flow of the fluid channel, thereby ensuring the heat exchange performance of the first heat exchange element 11 (second heat exchange element 12). This also helps to reduce the height of the first heat exchange element 11 (second heat exchange element 12), which is beneficial to the thinning of the total heat exchange core assembly 10, and thus to the thinning of the air handling equipment 1.

[0068] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above embodiments.

[0069] For example, in the above embodiments, the heat exchange elements can be stacked to form a total heat exchange core. The total heat exchange core is installed in the fluid channel of air handling equipment such as a total heat exchanger, a fresh air unit, and an indoor air conditioning unit with ventilation function, to perform heat exchange treatment on the indoor and outdoor air flowing through the fluid channel.

[0070] Heat exchange elements can also be used for humidification. Multiple heat exchange elements are stacked to form a humidification core. Air and water flow through the fluid channels of adjacent heat exchange elements, respectively. That is, the fluid channels include airflow channels and water flow channels. The humidification core is placed in the humidification device. When air flows through the humidification core, the water in the water flow channels of the humidification core is carried into the airflow channels, thereby humidifying the air.

[0071] When using heat exchange elements to construct the humidification core, it is preferable that the water flow channel extends vertically, and the airflow channel extends intersecting with the water flow channel. Furthermore, it is preferable that both ends of the water flow channel are sealed by means of adhesive or other methods to prevent water leakage.

[0072] When a heat exchange element is used to construct the humidification core, the heat exchange plate of the heat exchange element can be made of a membrane or paper with moisture-permeable function. The membrane or paper includes a substrate layer and a moisture-permeable layer disposed on the substrate layer. Furthermore, it is preferable that the height of the reinforcing ribs is less than the height of the partition ribs. This ensures that the strength of the heat exchange element can withstand water pressure and air pressure, while reducing obstruction to airflow and water flow, thereby increasing the humidification effect.

[0073] Furthermore, in the above embodiments, the air handling equipment can be used alone or in combination, for example, by placing the humidifier downstream of the air supply path of the total heat exchanger. The two devices can be installed as a single unit or separately.

[0074] Furthermore, in the above embodiments, the first heat exchange element 11 may also include another frame disposed on the other side of the heat exchange plate 111 in the thickness direction. This other frame includes partition ribs extending in a direction intersecting the first direction and separating adjacent fluid channels. In this case, the other frame may also include reinforcing ribs similar to reinforcing rib 1122.

[0075] Furthermore, in the above embodiments, the second heat exchange element 12 may also include another frame disposed on the other side of the heat exchange plate 121 in the thickness direction. This other frame includes partition ribs extending in a direction intersecting the third direction and separating adjacent fluid channels. In this case, the other frame may also include reinforcing ribs similar to reinforcing rib 1222.

[0076] Furthermore, in the above embodiments, the frame 112 (frame 122) can also be bonded to one side of the heat exchange plate 111 (heat exchange plate 121) in the thickness direction by adhesive (bonding agent).

[0077] Furthermore, in the above embodiment, the inner wall of the slot formed on the frame of the frame 112 (frame 122) constitutes an anti-overflow adhesive structure, but it is not limited to this. As an anti-overflow adhesive structure, the inner wall may be replaced or the following structure may be formed on the basis of the inner wall: a baffle that protrudes toward and abuts against the other side is formed on at least one of the slot of a heat exchange element and the edge of another heat exchange element that engages with the slot (for example, at position D in FIG4, extending along the length direction of the slot). Thus, when adhesive is applied to the edge of another heat exchange element that engages with the slot of a heat exchange element, the overflow of adhesive toward the inner side of the frame can be further suppressed, and the baffle can also prevent external gas from mixing into the fluid channel. In addition, in the above embodiment, the number of partition ribs 1121 (partition ribs 1221) and the number of reinforcing ribs 1122 (reinforcing ribs 1222) can be appropriately set as needed.

[0078] Furthermore, in the above embodiments, the reinforcing rib 1122 is attached to one side of the substrate layer of the heat exchange plate 111, and the reinforcing rib 1222 is attached to one side of the substrate layer of the heat exchange plate 121. However, it is not limited to this. The reinforcing rib 1122 can also be separated from the substrate layer of the heat exchange plate 111, and the reinforcing rib 1222 can also be separated from the substrate layer of the heat exchange plate 121.

[0079] Furthermore, in the above embodiments, the shape of frame 112 (frame 122) is not limited to a rectangle, but can also be a circle or other shapes.

[0080] Furthermore, in the above embodiments, the frame 112 (frame 122) may also be a hollow plate or a metal part.

[0081] Furthermore, in the above embodiments, the first heat exchange element 11 and the second heat exchange element 12 are formed with substantially the same structure, but are not limited thereto. The first heat exchange element 11 and the second heat exchange element 12 may also be formed with different structures. For example, the reinforcing ribs of one of the first heat exchange element 11 and the second heat exchange element 12 may be omitted.

[0082] In addition, as shown in FIG11, in the above embodiment, the edge where two adjacent surfaces of the total heat exchange core assembly 10 intersect may also have a bracket 15, which is fixedly connected (e.g., riveted) to the top plate 13 and the bottom plate, thereby further improving the overall strength.

[0083] In the case of setting up the support 15, in order to reduce the obstruction of the support 15 to the fluid and increase the fluid passage area, the support 15 can be set as a structure that is narrow in the middle and wide at both ends (that is, the part near the top plate 13 and the bottom plate is wider than the middle).

[0084] In addition, in the above embodiments, handles can be provided on the top plate 13 and the bottom plate of the total heat exchange core assembly 10 to facilitate the installation and maintenance of the total heat exchange core assembly 10.

[0085] In addition, in the above embodiments, the total heat exchange core assembly 10 may also include a guide rail, which may be fixed on the housing KT or on the inner shell formed of foamed material inside the housing KT.

[0086] It should be understood that within the scope of this invention, the various parts of the embodiments can be freely combined, or the various parts of the embodiments can be appropriately modified or omitted.
