Summary of the Invention
Problems to be Solved by the Invention
[0004] When a plate-like member is press-worked into a corrugated shape to form a corrugated flow path member having a meandering, bent, etc. flow path (fluid passage), compared to the straight portion of the flow path, the amount of deformation at the bent portion of the flow path becomes large, making it difficult to mold the desired height in the flow path, and there are problems such as the possibility of strength reduction due to thinning at the bent portion of the flow path, which may cause a decrease in the performance (heat exchange capacity) of the heat exchanger.
[0005] An object of the present disclosure is to provide a flow path member and a heat exchanger that can suppress a decrease in the performance of the heat exchanger while having a bent flow path.
Means for Solving the Problems
[0006] The flow channel member of the first embodiment is a corrugated plate-shaped member used in a heat exchanger (1) to form a fluid flow channel. The flow channel member includes a first flow channel section (11A) and a second flow channel section (11B) arranged adjacent to the first flow channel section (11A) and separate from the first flow channel section (11A). The first flow channel section (11A) has a first flow channel (R1) extending along a first direction (V3), and the second flow channel section (11B) has a second flow channel (R2) extending along a second direction (V2) different from the first direction (V3). Viewed in the vertical direction (V1), the first opposing portion (11A1) of the first flow channel portion (11A) that faces the second flow channel portion (11B) extends in a direction other than that perpendicular to the first direction (V3), and viewed in the height direction (V1) of the flow channel member (111), the second opposing portion (11B1) of the second flow channel portion (11B) that faces the first flow channel portion (11A) extends in a direction other than that perpendicular to the second direction (V2).
[0007] In the first embodiment, the flow channel member (111) has a bent flow channel due to the first flow channel (R1) and the second flow channel (R2), while suppressing a decrease in the performance of the heat exchanger (1).
[0008] In the second embodiment, as in the first embodiment, when viewed in the height direction (V1) of the flow channel member (111), each of the first opposing portion (11A1) and the second opposing portion (11B1) extends along a direction other than the first direction (V3) and a direction other than the second direction (V2).
[0009] In the second embodiment, a flow path that bends from a first direction (V3) to a second direction (V2) can be easily formed by a plurality of flow path sections (11A, 11B).
[0010] In the third embodiment, as in the first or second embodiment, the first opposing portion (11A1) of the first flow channel (11A) is parallel to the second opposing portion (11B1) of the second flow channel (11B) when viewed in the height direction (V1) of the flow channel member (111).
[0011] In the third embodiment, the first flow channel (11A) can be easily abutted against the second flow channel (11B), thereby easily connecting the first flow channel (R1) formed in the first flow channel (11A) and the second flow channel (R2) formed in the second flow channel (11B).
[0012] In the fourth embodiment, in any one of the first to third embodiments, the portion of the first flow path (R1) located at the first opposing portion (11A1) is connected to the portion of the second flow path (R2) located at the second opposing portion (11B1).
[0013] In the fourth embodiment, the first channel (R1) formed in the first channel section (11A) and the second channel (R2) formed in the second channel section (11B) can be connected by the first opposing section (11A1) and the second opposing section (11B1).
[0014] The fifth embodiment of the heat exchanger comprises a flow channel member according to any one of the first to fourth embodiments.
[0015] A sixth embodiment is a fifth embodiment comprising a partition member (200) on which the flow channel member (111) is placed, wherein the first flow channel section (11A) or the second flow channel section (11B) includes a peak (111a) projecting in a direction away from the partition member (200), and the partition member (200) includes a convex portion (210) opposite to the peak (111a) that is convex in the direction of projection of the peak (111a).
[0016] In the sixth embodiment, the first flow channel (11A) or the second flow channel (11B) can be easily positioned on the partition member (200). [Brief explanation of the drawing]

Mode for Carrying Out the Invention
[0018] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. Note that the present disclosure is not limited to the embodiments shown below, and various modifications are possible without departing from the technical idea of the present disclosure. Since each drawing is for conceptually explaining the present disclosure, dimensions, ratios, or numbers may be exaggerated or simplified as necessary for easy understanding. In each embodiment, modification example, and figure, the same or corresponding parts are denoted by the same reference numerals, and detailed descriptions and descriptions of the accompanying effects and the like are not repeated.
[0019] (1) Overall Configuration The heat exchanger (1) according to the embodiment is a device that performs heat exchange between a plurality of fluids (refrigerants). The heat exchanger (1) is formed of a metal material such as stainless steel or aluminum, for example. As shown in FIGS. 1 and 2, the heat exchanger (1) includes a plurality of fluid layers (100) to be laminated and a partition member (200). The constituent members of the heat exchanger (1) are joined to each other by, for example, brazing.
[0020] As shown in FIG. 1, fluid flows in each of the plurality of fluid layers (100). The plurality of fluid layers (100) are stacked along the first direction (V1). The first direction (V1) indicates the stacking direction of the plurality of fluid layers (100). The plurality of fluid layers (100) include a first layer (110) and a second layer (120). The first layer (110) and the second layer (120) are alternately stacked along the first direction (V1). The first layer (110) and the second layer (120) are arranged adjacent to each other in the first direction (V1). Different types of fluids flow in the first layer (110) and the second layer (120).
[0021] As shown in FIGS. 1 and 2, the first layer (110) includes a first flow path member (111) and a first spacer member (112). The first flow path member (111) forms a flow path for the first fluid. In the present embodiment, the first flow path member (111) forms a bent flow path. The first flow path member (111) has a corrugated shape. The first flow path member (111) includes a peak portion (111a) that protrudes toward one side (V11) in the first direction (V1) and a valley portion (111b) that protrudes toward the other side (V12) in the first direction (V1). The valley portion (111b) and the peak portion (111a) extend along a direction parallel to each other. The direction in which the valley portion (111b) and the peak portion (111a) extend indicates the extending direction of the first flow path member (111). The first flow path member (111) flows the first fluid along the direction in which the valley portion (111b) and the peak portion (111a) extend. The first flow path member (111) has a corrugated shape in which the peak portion (111a) and the valley portion (111b) are alternately arranged. A first flow path space (W1) surrounded by the peak portion (111a) and the partition member (200) and a second flow path space (W2) surrounded by the valley portion (111b) and the partition member (200) serve as flow paths for the first fluid. The first spacer member (112) is a member for preventing the first fluid from leaking from the first flow path member (111) to the outside of the first flow path member (111). The first spacer member (112) is formed in an annular shape. The first flow path member (111) is disposed inside the first spacer member (112). The first spacer member (112) is in contact with the partition members (200) on both sides in the first direction (V1).
[0022] As shown in Figures 1 and 3, the second layer (120) includes a second flow channel member (121) and a second spacer member (122). The second flow channel member (121) forms a flow channel for the second fluid. In this embodiment, the second flow channel member (121) forms a flow channel extending along the second direction (V2). The second flow channel member (121) has a corrugated shape. The second spacer member (122) is a member for preventing the second fluid from leaking from the second flow channel member (121) to the outside of the second flow channel member (121). The second spacer member (122) includes a first spacer portion (122a) and a second spacer portion (122b). The second flow channel member (121) is positioned between the first spacer portion (122a) and the second spacer portion (122b). The second spacer member (122) is in contact with the partition wall members (200) on both sides in the first direction (V1).
[0023] As shown in Figures 1 and 4, the partition member (200) is a flat plate-shaped member. The partition member (200) is placed between the first layer (110) and the second layer (120) which are adjacent in the first direction (V1).
[0024] As shown in Figures 2 to 4, in each of the first spacer member (112), the second spacer member (122), and the partition wall member (200), a first side surface (1121, 1221, 201) and a first recess (1122, 1222, 202) and a second recess (1123, 1223, 203) are provided on the other side (V32) in the third direction (V3). The first recess (1122, 1222, 202) and the second recess (1123, 1223, 203) are spaced apart in the second direction (V2). Each of the first spacer member (112), the second spacer member (122), and the partition wall member (200) is provided with a second side surface (1124, 1224, 204) and a third recess (1125, 1225, 205) recessed to the second side surface (1124, 1224, 204) on one side (V21) of the second direction (V2). Each of the first spacer member (112), the second spacer member (122), and the partition wall member (200) is provided with a third side surface (1126, 1226, 206) and a fourth recess (1127, 1227, 207) recessed to the third side surface (1126, 1226, 206) on the other side (V22) of the second direction (V2). The spaces formed by the first recesses (1122, 1222, 202) communicate with each other to form the first space (T1). The spaces formed by the second recesses (1123, 1223, 203) communicate with each other to form the second space (T2). The spaces formed by the third recesses (1125, 1225, 205) communicate with each other to form the third space (T3). The spaces formed by the fourth recesses (1127, 1227, 207) communicate with each other to form the fourth space (T4). The first space (T1) communicates with the flow path of the first flow path member (111) through the gap (U1) formed between the first spacer member (112) and the first flow path member (111). The second space (T2) communicates with the flow path of the first flow path member (111) through the gap (U2) formed between the first spacer member (112) and the first flow path member (111). The first space (T1) and the second space (T2) do not communicate with the second flow channel member (121) because they face the second spacer portion (122b). The third space (T3) and the fourth space (T4) do not communicate with the first flow channel member (111) because they face the first spacer member (112).The third space (T3) and the fourth space (T4) face the second flow channel member (121) and communicate with the second flow channel member (121). The first direction (V1), the second direction (V2), and the third direction (V3) are perpendicular to each other.
[0025] As shown in Figures 2 to 5, the first spacer member (112), the second spacer member (122), and the partition wall member (200) are arranged within a space enclosed by plate-shaped members (P13, P22, P32, 300). Plate-shaped members (P13) are fixed to the first sides (1121, 1221, 201) of the first spacer member (112), the second spacer member (122), and the partition wall member (200). A first pipe (P11) and a second pipe (P12) are provided on the plate-shaped member (P13). The first pipe (P11) communicates with the first space (T1). The second pipe (P12) communicates with the second space (T2). Plate-shaped members (P22) are fixed to the first spacer member (112), the second spacer member (122), and the second side surfaces (1124, 1224, 204) of the partition wall member (200). A third pipe (P21) is provided on the plate-shaped member (P22). The third pipe (P21) communicates with the third space (T3). Plate-shaped members (P32) are fixed to the third side surfaces (1126, 1226, 206) of the first spacer member (112), the second spacer member (122), and the partition wall member (200). A fourth pipe (P31) is provided on the plate-shaped member (P32). The fourth pipe (P31) communicates with the fourth space (T4).
[0026] As shown in Figures 2 to 5, the first fluid is sent to the first space (T1) through the first pipe (P11). The first fluid sent to the first space (T1) flows through the channel of the first flow channel member (111) and is then sent to the second space (T2). The first fluid sent to the second space (T2) is discharged through the second pipe (P12). The second fluid is sent to the third space (T3) through the third pipe (P21). The second fluid sent to the third space (T3) flows through the channel of the second flow channel member (121) and is then sent to the fourth space (T4). The first fluid sent to the fourth space (T4) is discharged through the fourth pipe (P31).
[0027] The heat exchanger (1) is used, for example, in a heating appliance such as central heating. In this case, heat exchange occurs between a first fluid flowing through the channel of the first flow channel member (111) and a second fluid flowing through the channel of the second flow channel member (121), so that the first fluid, which is water, is heated by the heat of the second fluid, which is propane or carbon dioxide, and becomes hot water. This hot water is discharged through the second pipe (P2) and circulates through pipes laid inside the wall. As a result, the room is heated. The heat exchanger (1) may also be used in a water heater. The water heater supplies hot water generated by the heat exchanger (1) through heat exchange between the first fluid and the second fluid.
[0028] (2) First flow channel member The first flow channel member (111) will now be described.
[0029] As shown in Figure 2, the corrugated first flow channel member (111) has a structure in which it includes multiple flow channel sections and the multiple flow channel sections are arranged to connect each other. The first flow channel member (111) forms a flow channel (R) for the first fluid by the multiple flow channel sections arranged to connect each other. In the multiple flow channel sections, the flow channels (R) formed in adjacent flow channel sections are connected to each other. The multiple flow channel sections include the first flow channel section (11A) to the seventh flow channel section (11G). The flow channel (R) for the first fluid includes the first flow channel section (R1) to the seventh flow channel section (R7). The first flow channel section (11A) to the seventh flow channel section (11G) are each separate members. The first flow channel section (11A) to the seventh flow channel section (11G) each have the first flow channel section (R1) to the seventh flow channel section (R7) formed within them. The first channel section (11A) is adjacent to the second channel section (11B), the second channel section (11B) is adjacent to the third channel section (11C), the third channel section (11C) is adjacent to the fourth channel section (11D), the fourth channel section (11D) is adjacent to the fifth channel section (11E), the fifth channel section (11E) is adjacent to the sixth channel section (11F), and the sixth channel section (11F) is adjacent to the seventh channel section (11G). The first channel section (R1) is connected to the second channel section (R2), the second channel section (R2) is connected to the third channel section (R3), the third channel section (R3) is connected to the fourth channel section (R4), the fourth channel section (R4) is connected to the fifth channel section (R5), the fifth channel section (R5) is connected to the sixth channel section (R6), and the sixth channel section (R6) is connected to the seventh channel section (R7).
[0030] The following describes the connection structure between the adjacent first channel section (11A) and the second channel section (11B). The connection structures of other adjacent channel sections, such as the connection structure between the second channel section (11B) and the third channel section (11C), are similar to the connection structure between the first channel section (11A) and the second channel section (11B), so their explanation will be omitted.
[0031] The first flow channel section (11A) and the second flow channel section (11B) are corrugated plate-shaped members. The first flow channel section (11A) and the second flow channel section (11B) form a flow channel (a flow channel for the first fluid) that extends in a straight line. The flow channel formed by the first flow channel section (11A) extends in a different direction from the flow channel formed by the second flow channel section (11B). The first flow channel section (11A) and the second flow channel section (11B) carry the first fluid along different straight directions. Note that the flow channels formed by the first flow channel section (11A) and the second flow channel section (11B) (the first flow channel (R1) and the second flow channel (R2)) do not have to extend in a straight line, and may be slightly curved or bent.
[0032] A first flow channel (R1) extending along a third direction (V3) is formed in the first flow channel section (11A). The first flow channel section (11A) includes a first opposing section (11A1). The first opposing section (11A1) is the portion of the first flow channel section (11A) that faces the second flow channel section (11B).
[0033] A second flow channel (R2) is formed in the second flow channel section (11B) that extends in a direction different from the third direction (V3). In this embodiment, the second flow channel (R2) extends in a second direction (V2) perpendicular to the third direction (V3). The second flow channel section (11B) includes a second opposing section (11B1). The second opposing section (11B1) is the portion of the second flow channel section (11B) that faces the first flow channel section (11A).
[0034] As shown in Figures 2, 6(a), and 6(b), the first flow channel section (11A) and the second flow channel section (11B) are arranged so that the first opposing section (11A1) and the second opposing section (11B1) abut against each other. The first flow channel section (11A) and the second flow channel section (11B) are arranged so that the peaks (111a, a1) of the first flow channel section (11A) located in the first opposing section (11A1) abut against the peaks (111a, a2) of the second flow channel section (11B) located in the second opposing section (11B1), and the valleys (111b, b1) of the first flow channel section (11A) located in the first opposing section (11A1) abut against the valleys (111b, b2) of the second flow channel section (11B) located in the second opposing section (11B1). A bent channel is formed by the first channel (R1) and the second channel (R2).
[0035] The first flow channel (11A) is connected to the second flow channel (11B) at its opposing sections (11A1, 11B1). The portion of the first flow channel (R1) located at the first opposing section (11A1) is connected to the portion of the second flow channel (R2) located at the second opposing section (11B1). As a result, the first fluid that has finished flowing through the first flow channel (R1) can flow into the second flow channel (R2).
[0036] As shown in Figure 2, when viewed in the height direction (V1) of the first flow channel member (111), the first opposing portion (11A1) is parallel to the second opposing portion (11B1). The first opposing portion (11A1) is in contact with the second opposing portion (11B1). A small gap may exist between the first opposing portion (11A1) and the second opposing portion (11B1). The height direction (V1) of the first flow channel member (111) is the direction in which a third virtual line (L3) extends, which is perpendicular to a first virtual line (L1) connecting adjacent peaks (111a) and a second virtual line (L2) connecting adjacent valleys (111b) in the first flow channel member (111) (see Figure 7(b)). In this embodiment, the first direction (V1) is defined as the height direction (V1) of the first flow channel member (111).
[0037] As shown in Figure 2, a first flow path (R1) is formed in the first flow path section (11A) extending along the first direction (V3). A second flow path (R2) is formed in the second flow path section (11B) connected to the first flow path (R1) and extending along the second direction (V2), which is different from the first direction (V3). Viewed in the height direction (V1), the first opposing section (11A1) extends along a direction other than the direction perpendicular to the third direction (V3) (the direction in which the first flow path (R1) extends). That is, viewed in the height direction (V1), the first opposing section (11A1) extends so as to be inclined at an acute or obtuse angle with respect to the direction perpendicular to the third direction (V3). In this embodiment, viewed in the height direction (V1), the first opposing section (11A1) extends along a direction other than the second direction (V2) and extends so as to be inclined at 45 degrees with respect to the second direction (V2). Viewed in the height direction (V1), the first opposing portion (11A1) extends along a direction other than the second direction (V2) and a direction other than the third direction (V3).
[0038] As shown in Figure 2, when viewed in the height direction (V1), the second opposing portion (11B1) extends along a direction other than that perpendicular to the second direction (V2) (the direction in which the second flow path (R2) extends). That is, when viewed in the height direction (V1), the second opposing portion (11B1) extends so as to be inclined at an acute or obtuse angle with respect to the direction perpendicular to the second direction (V2). In this embodiment, when viewed in the height direction (V1), the second opposing portion (11B1) extends along a direction other than the third direction (V3) and so as to be inclined at 45 degrees with respect to the third direction (V3). When viewed in the height direction (V1), the second opposing portion (11B1) extends along a direction other than the second direction (V2) and a direction other than the third direction (V3).
[0039] When the first fluid flows from the first channel (R1) into the second channel (R2), its flow direction changes. In this embodiment, when the first fluid flows from the first channel (R1) into the second channel (R2), its flow direction changes by 90 degrees.
[0040] (3) Effects As described above, the first flow channel (11A) has a first flow channel (R1) extending along the first direction (V3), and the second flow channel (11B) has a second flow channel (R2) extending along the second direction (V2) which is different from the first direction (V3). When viewed in the height direction (V1) of the first flow channel member (111), the first opposing portion (11A1) of the first flow channel (11A) that faces the second flow channel (11B) extends along a direction other than the direction perpendicular to the third direction (V3), and the second opposing portion (11B1) of the second flow channel (11B) that faces the first flow channel (11A) extends along a direction other than the direction perpendicular to the second direction (V2). This allows the first flow path (R1) and the second flow path (R2), which extend in different directions, to be connected, and a bent flow path can be formed by the first flow path (R1) and the second flow path (R2), which extend in different directions. As a result, the bent portion of the flow path is formed at the connection point between the first flow path section (11A) and the second flow path section (11B), which are separate components, thus suppressing problems that occur when forming a bent flow path by press-forming a single component into a corrugated shape (such as difficulty in forming the target height in the flow path due to the larger amount of deformation at the bent portion of the flow path compared to the straight portion of the flow path, and a decrease in strength at the bent portion of the flow path due to thinning of the material). As a result, a decrease in the performance of the heat exchanger (1) can be suppressed.
[0041] Furthermore, in order to manufacture a mold for forming a single channel with a bent shape, the shape of the molding surface that forms the bend of the channel in the mold is complex (fine), so the tools used to manufacture the mold also become thinner, increasing the manufacturing time and cost of the mold. However, in this embodiment, by separating the first channel section (11A) and the second channel section (11B), a bent channel is not formed with a single channel. Instead, the first channel section (11A) and the second channel section (11B), which extend in different directions from each other, are connected to form a bent channel, and the separate first channel section (11A) and second channel section (11B) form the bent channel, thus eliminating the need for the complex structure described above in the mold. As a result, in this embodiment, it is possible to suppress the increase in the manufacturing time and cost of the mold for manufacturing the first channel member (111).
[0042] (4) Variations As shown in Figures 7(a) and 7(b), in the heat exchanger (1), the partition member (200) may include a protrusion (210) that protrudes in a first direction (V1) (the direction in which the peak (111a) of the first flow channel member (111) protrudes). The protrusion (210) is positioned opposite the peak (111a) of the first flow channel member (111) which is placed on the partition member (200). The peak (111a) protrudes in a direction away from the partition member (200) on which the protrusion (210) is formed (first direction (V1)). The protrusion (210) is positioned in the first flow channel space (W1). The protrusions (210) are provided at locations opposite to the peaks (111a) of the first flow channel (11A) and / or opposite to the peaks (111a) of the second flow channel (11B). This allows the first flow channel (11A) and / or the second flow channel (11B) to be placed on the partition member (200) by fitting the protrusions (210) into the first flow channel space (W1). As a result, the first flow channel (11A) and / or the second flow channel (11B) can be easily positioned on the partition member (200).
