After the top cover and the bottom cover are fixed, the half cavities on the top cover and the bottom cover form a number of complete cavities, and these cavities are used to flow the refrigerant. A brazing material is laid between the top cover and the bottom cover and is used to fix the top cover and the bottom cover by welding. However, it is not possible to determine from the outside whether an internal leak occurs between two adjacent cavities, and it is difficult to detect the leak inside the piping device, and it is also not possible to determine the location of the internal leak during after-sales maintenance.

[0051] A piping device 10 according to an embodiment of the first aspect of the present invention will be described in detail below with reference to a combination of Figs. 1 to 12.

[0052] As shown in Figures 1, 7 and 8, a piping device 10 according to an embodiment of the first aspect of the present application can include a first cover body 1 and a second cover body 2, the first cover body 1 has a first bonding plate 11, and the second cover body 2 has a second bonding plate 21, the first bonding plate 11 and the second bonding plate 21 are bonded together face to face to form a first cavity 51, a second cavity 52 and an isolation portion 4, the first cavity 51 and the second cavity 52 are used for the flow of a refrigerant, the isolation portion 4 is located between the first cavity 51 and the second cavity 52, and the arrangement path of the isolation portion 4 is The isolating section 4 laterally faces the extension path of the first cavity 51 and the extension path of the second cavity 52 on both sides, that is, any line connecting any two points between the first cavity 51 and the second cavity 52 passes through the isolating section 4, thus ensuring that the area between the first cavity 51 and the second cavity 52 is completely covered, and when any position of one of the cavities 5 among the first cavity 51 and the second cavity 52 causes internal leakage to the other cavity 5, the isolating section 4 can accurately detect the internal leakage phenomenon, thereby improving the safety of use of the piping device 10.

[0053] 2 to 4 and 6, a plurality of first recesses 12 are provided in first laminated plate 11, and the plurality of first recesses 12 are recessed in a first direction (i.e., direction M). A plurality of second recesses 22 are provided in second laminated plate 21, and the plurality of second recesses 22 are recessed in a direction opposite to the first direction (i.e., direction N). In other words, first recesses 12 are recessed in a direction away from second laminated plate 21, and second recesses 22 are recessed in a direction away from first laminated plate 11. The second recesses 22 correspond to the first recesses 12 respectively, specifically, the number of the second recesses 22 and the first recesses 12 are similar and the positions correspond to each other, each second recess 22 is combined with a corresponding first recess 12 to form a complete cavity 5, a plurality of second recesses 22 are combined with a corresponding first recess 12 to form a plurality of complete cavities 5, the plurality of cavities 5 are separated from each other, a refrigerant normally flows in the cavity 5, and when the piping device 10 is used in the cooling system of a cooling equipment such as an air conditioner or a refrigerator, the refrigerant can exert the corresponding cooling function.

[0054] The plurality of cavities 5 include a first cavity 51 and a second cavity 52, and the isolating part 4 is opened in the first laminated plate 11 and the second laminated plate 21 between the first cavity 51 and the second cavity 52. ​​The arrangement path of the isolating part 4 ensures that the first cavity 51 and the second cavity 52 on both sides can be isolated, thus the isolating part 4 can completely cover the area between the first cavity 51 and the second cavity 52, and when any position of one cavity 5 among the first cavity 51 and the second cavity 52 causes internal leakage to the other cavity 5, the isolating part 4 can accurately detect the internal leakage phenomenon, thereby improving the use safety of the piping device 10.

[0055] It is necessary to explain that there may be one or more first cavities 51, and there may be one or more second cavities 52. Between any two adjacent cavities 5, a separator 4 is provided in both the first laminated plate 11 and the second laminated plate 21.

[0056] For example, in the embodiment shown in FIGS. 7 and 8, there are a plurality of first cavities 51 and a plurality of second cavities 52, and adjacent first cavities 51 and second cavities 52 are separated by isolating portions 4.

[0057] In the embodiment shown in FIG. 1, there is one first cavity 51 and one second cavity 52 , and the first cavity 51 and the second cavity 52 are separated by the isolating portion 4 .

[0058] As shown in FIGS. 2 to 4 and 6, the isolating portion 4 may have at least one first seam 41 and at least one second seam 42, the first seam 41 being provided penetrating the first laminated plate 11, and the second seam 42 being provided penetrating the second laminated plate 21. Specifically, the first seam 41 is opened in the first laminated plate 11, and the first seam 41 is provided in the thickness direction of the first laminated plate 11 (i.e. The first seam 41 penetrates the first laminated plate 11 in the thickness direction (i.e., MN direction) of the second laminated plate 21, and the second seam 42 penetrates the second laminated plate 21 in the thickness direction (i.e., MN direction) of the second laminated plate 21, and the first seam 41 and the second seam 42 have the same arrangement path, i.e., the arrangement path of the first seam 41 and the arrangement path of the second seam 42 are both the same as the arrangement path of the isolation section 4.

[0059] In a plane projection parallel to the bonding surface between the first laminated plate 11 and the second laminated plate 21, i.e., in a plane perpendicular to the straight line MN, one first joint 41 is connected to at least a part of at least one second joint 42 to form at least a part of the arrangement path of the isolation part 4. In other words, there is a certain crossing distance between the first joint 41 and the second joint 42 on the arrangement path of the isolation part 4, and thus, when the first joint 41 does not cross the second joint 42, it is possible to avoid the case where there is a blind spot for internal leakage detection, that is, there is no blind spot for internal leakage detection, and the first cavity 51 and the second cavity 52 are communicated with each other, and when internal leakage occurs in the refrigerant in the first cavity 51 and the second cavity 52, the refrigerant due to internal leakage can overflow from the first joint 41 or the second joint 42 and leak to the outside, and it is possible to ensure that the refrigerant will not flow into the adjacent cavity 5 due to internal leakage and affect the performance of the cooling equipment.

[0060] The piping device 10 according to the embodiment of the present application is provided with the isolation portion 4, which can accurately detect whether an internal leak occurs between the first cavity 51 and the second cavity 52. ​​As a result, if the flow paths in the first cavity 51 and the second cavity 52 are penetrated due to a structural defect, causing an internal leak, the flow path will not leak to the outside through the isolation portion 4, and will not flow into the adjacent cavity 5 due to an internal leak, thereby preventing the performance of the cooling equipment from being affected. When detecting an internal leak in the piping device 10, the leak detection can be completed at the same time as the internal leak, and it can be ensured that there is no need to detect the flow paths between each of the first cavity 51 and the second cavity 52 individually. This greatly improves the leak detection efficiency of the piping device 10, and makes it easier to determine the location of the internal leak during subsequent maintenance.

[0061] In some embodiments of the present application, as shown in Figs. 3 to 5, the first seams 41 are multiple, and two adjacent first seams 41 are partitioned by a first partition 13, thus ensuring that the first lid 1 has good strength, the first seams 41 do not excessively weaken the strength of the first lid 1, and the structure of the first seams 41 is simple and easy to process. The first partition 13 is aligned with the second seam 42, and the length of the second seam 42 is equal to or longer than the length of the first partition 13. Similarly, the second seams 42 are multiple, and two adjacent second seams 42 are partitioned by a second partition 23, thus ensuring that the second lid 2 has good strength, and the second partition does not excessively weaken the second lid 2, and the structure of the second partition is simple and easy to process. The second partition 23 is aligned with the first joint 41, and the length of the first joint 41 is equal to or greater than the length of the second partition 23. For example, referring to the size relationship in FIG. 5, the length of the first joint 41 is L1, the length of the second joint 42 is L2, the length of the first partition 13 is L3, and the length of the second partition 23 is L4, where L1 and L4 satisfy the relationship: L1≧L4, and L2 and L3 satisfy the relationship: L2≧L3. In this way, it is possible to ensure that the isolation part 4 is completely covered between the first cavity 51 and the second cavity 52, there is no blind spot for detecting internal leakage, and any position of one cavity 5 is connected to another cavity 5, so that when an internal leakage occurs, the refrigerant caused by the internal leakage can overflow from the isolation part 4, which makes it easy for the user to quickly identify the location of the internal leakage.

[0062] Optionally, referring to FIG. 6, the first seam 41 and the second seam 42 can be configured as arc-shaped slits, and the multiple first seams 41 and the multiple second seams 42 are all arranged along the same arc-shaped path, i.e., the isolation portion 4 is arranged along the same arc-shaped path.

[0063] Alternatively, referring to FIG. 5, the first seam 41 and the second seam 42 can be configured as long linear slits, and the multiple first seams 41 and the multiple second seams 42 are all arranged along the same linear path, i.e., the separator 4 is arranged along the same linear path.

[0064] Also optionally, the first seam 41 and the second seam 42 can be configured as a zigzag slit, and the multiple first seams 41 and the multiple second seams 42 are all arranged along the same zigzag path, i.e., the isolation portion 4 is arranged along the same zigzag path.

[0065] 5 to 6 and 8 to 10, in a direction perpendicular to the bonding surface between the first laminated plate 11 and the second laminated plate 21, i.e., in the direction of a straight line MN, each first seam 41 is aligned with a part of the adjacent second seam 42 and shifted to another part. Similarly, each second seam 42 is aligned with a part of the adjacent first seam 41 and each second seam 42 is shifted to the other part of the adjacent first seam 41. In other words, the first joint 41 and the second joint 42 are offset from each other, and there is a certain cross distance between the first joint 41 and the second joint 42 in the longitudinal direction, so there is no blind spot for detecting internal leakage, and the first cavity 51 and the second cavity 52 are connected. When an internal leakage occurs in the refrigerant in the first cavity 51 and the second cavity 52, the refrigerant due to the internal leakage can overflow from the first joint 41 or the second joint 42 and leak to the outside, and it is possible to ensure that the internal leakage does not flow into the adjacent cavity 5 and affect the performance of the air conditioning equipment.

[0066] In some embodiments of the present application, the alignment length of each first seam 41 and the adjacent second seam 42 does not exceed 1 / 2 the length of the first seam 41, and does not exceed 1 / 2 the length of the second seam 42. Referring to the size relationship in FIG. 5, the alignment length of each first seam 41 and the adjacent second seam 42 is L5, where L1 and L5 satisfy the relationship: L5≦L1 / 2, and L2 and L5 satisfy the relationship: L5≦L2 / 2. This can prevent the first seam 41 and the second seam 42 from being too long, which would excessively weaken the strength of the first cover 1 and the second cover 2.

[0067] In some embodiments of the present application, the alignment length of each first seam 41 and the adjacent second seam 42 is 1 / 6 or more of the length of the first seam 41, and 1 / 6 or more of the length of the second seam 42. Referring to the size relationship in FIG. 5, the alignment length of each first seam 41 and the adjacent second seam 42 is L5, where L1 and L5 satisfy the relationship: L5≧L1 / 6, and L2 and L5 satisfy the relationship: L5≧L2 / 6. This ensures the continuity of detection between the first seam 41 and the adjacent second seam 42, and there is no blind spot for internal leakage detection.

[0068] In some embodiments of the present application, the first seams 41 are multiple, the lengths of the multiple first seams 41 are equal, and the distance between any two adjacent first seams 41 is equal; the second seams 42 are multiple, the lengths of the multiple second seams 42 are equal, and the distance between any two adjacent second seams 42 is equal. In other words, referring to FIG. 5, the length of the multiple first seams 41 is L1, the length of the first partition 13 between any two adjacent first seams 41 is L3, the length of the multiple second seams 42 is L2, and the length of the second partition 23 between any two adjacent second seams 42 is L4. In this way, the distance between the first seams 41 and the second seams 42 is uniform, which is easy to process and is favorable for simplifying the processing process, and is favorable for saving manufacturing costs.

[0069] In some embodiments of the present application, the isolation portion 4 may be a ring-shaped structure surrounding the cavity 5, and as shown in Figures 7 to 8, a first cavity 51a is surrounded by a ring of isolation portions 4a, and in this manner, when an internal leak occurs in the surrounded first cavity 51a into other cavities 5 or the other cavities 5 into the first cavity 51a, the liquid due to the internal leak overflows from the isolation portion 4a surrounding the first cavity 51a.

[0070] In some other embodiments of the present application, the isolating portion 4 may have a non-ring-shaped structure, and for example, in an example as shown in Fig. 8, the isolating portion 4b is a long segment, and the extending direction of the isolating portion 4b is approximately the same as the extending direction of at least one isolated cavity 5. Also, in examples as shown in Figs. 11 and 12, the isolating portion 4 is a short segment, and it is sufficient to provide the isolating portion 4 only at one end where the first cavity 51 and the second cavity 52 approach each other, and since there is a small risk of internal leakage occurring in the area where the isolating portion 4 is not provided between the two adjacent cavities 5 in the arrangement path of the isolating portion 4, the isolating portion 4 does not need to be provided in that area.

[0071] In some embodiments of the present application, the first laminated plate 11 and the second laminated plate 21 are fixed by welding. For example, as shown in FIG. 2, the first laminated plate 11 and the second laminated plate 21 can be fixed by welding with a solder layer 3. The solder layer 3 covers the area other than the cavity 5 between the first laminated plate 11 and the second laminated plate 21, thereby reducing the risk of internal leakage. By avoiding the cavity 5, the solder layer 3 can prevent the solder layer 3 from entering the cavity 5 and affecting the flow rate of the coolant in the cavity 5, and can also prevent the solder layer 3 from contaminating the coolant in the cavity 5.

[0072] The solder layer 3 may be a brazing material. When the first cover 1 and the second cover 2 need to be welded and fixed, the first cover 1, the second cover 2 and the solder layer 3 can be furnace brazed together, and the brazing material can be melted and flowed at high temperature to fill the gap between the first cover 1 and the second cover 2, and the weld fixing between the first cover 1 and the second cover 2 can be completed after the brazing material cools and solidifies. If the flow of the brazing material is uneven, internal leakage is likely to occur between the two adjacent cavities 5 between the first cover 1 and the second cover 2, and the refrigerant in one cavity 5 will flow into the other cavity 5, affecting the normal use of the equipment. Since the piping device 10 according to the embodiment of the present application is provided with the isolating portion 4, when internal leakage of the brazing material occurs, the brazing material can overflow from the isolating portion 4 and leak to the outside, and the internal leakage will not flow into the adjacent cavities 5, affecting the performance of the cooling equipment.

[0073] Optionally, both the first laminated plate 11 and the second laminated plate 21 may be flat plates, which improves the uniformity of the flow of the solder layer 3 between the first laminated plate 11 and the second laminated plate 21 when melted, improves the welding fixing effect between the first laminated plate 11 and the second laminated plate 21, and simplifies the manufacturing process of the flat plates, which is advantageous for saving manufacturing costs.

[0074] In some other embodiments of the present application, the first cover 1 and the second cover 2 are connected and fixed by fasteners such as bolts and rivets. For example, in the example of Fig. 6 to Fig. 8, the first cover 1 is provided with a first mounting hole 14, the second cover 2 is provided with a second mounting hole 24, and a bolt is used to penetrate the first mounting hole 14 and the second mounting hole 24 and screwed into a nut, thereby realizing the connection between the first cover 1 and the second cover 2. Specifically, the first mounting hole 14 is opened in the first laminated plate 11, and the second mounting hole 24 is opened in the second laminated plate 21. In this way, after the first cover 1 and the second cover 2 are fastened together by the fastener, the first laminated plate 11 can be tightly attached to the second laminated plate 21.

[0075] In some embodiments of the present application, the material of the first cover 1 and the second cover 2 is stainless steel, that is, the first cover 1 and the second cover 2 are covers made of stainless steel. Compared with purple copper and copper, stainless steel has high strength and low cost, which is advantageous for reducing the overall cost of the piping device 10.

[0076] The piping device 10 according to the embodiment of the second aspect of the present invention will be described in detail below with reference to a combination of Figs. 1 to 5 and Figs. 11 to 12.

[0077] As shown in FIGS. 1 and 2, a piping device 10 according to an embodiment of the second aspect of the present application can include a first cover body 1, a second cover body 2 and a solder layer 3.

[0078] The first cover 1 includes a first laminated plate 11, which is provided with a plurality of first recesses 12, and which are recessed in a first direction (i.e., direction M). The second cover 2 includes a second laminated plate 21, which is provided with a plurality of second recesses 22, and which are recessed in a direction opposite to the first direction (i.e., direction N). In other words, the first recesses 12 are recessed in a direction away from the second laminated plate 21, and the second recesses 22 are recessed in a direction away from the first laminated plate 11. The second recesses 22 correspond to the first recesses 12 respectively, specifically, the number of the second recesses 22 and the first recesses 12 are similar and the positions correspond to each other, each second recess 22 is combined with a corresponding first recess 12 to form a complete cavity 5, a plurality of second recesses 22 are combined with a corresponding first recess 12 to form a plurality of complete cavities 5, the plurality of cavities 5 are separated from each other, a refrigerant normally flows in the cavity 5, and when the piping device 10 is used in the cooling system of a cooling equipment such as an air conditioner or a refrigerator, the refrigerant can exert the corresponding cooling function.

[0079] An isolation portion 4 is opened in the first laminating plate 11 and the second laminating plate 21 between two adjacent cavities 5, and the length of the isolation portion 4 is equal to or greater than the length of any one of the two adjacent cavities 5; in this way, the isolation portion 4 can completely cover the area between the two adjacent cavities 5, and when any position of one of the two adjacent cavities 5 causes internal leakage to the other cavity 5, both isolation portions 4 can accurately detect the internal leakage phenomenon, thereby improving the safety of use of the piping device 10.

[0080] The solder layer 3 is provided between the first laminated plate 11 and the second laminated plate 21, and the solder layer 3 is used to weld the first laminated plate 11 and the second laminated plate 21 together. The solder layer 3 may be a brazing material. When the first cover 1 and the second cover 2 need to be welded and fixed, the first cover 1, the second cover 2 and the solder layer 3 can be furnace brazed together, and the brazing material can be melted and flowed at high temperature to fill the gap between the first cover 1 and the second cover 2, and the weld fixing between the first cover 1 and the second cover 2 can be completed after the brazing material is cooled and solidified. If the flow of the brazing material is uneven, it is easy to cause internal leakage between the two adjacent cavities 5 between the first cover 1 and the second cover 2, and the refrigerant in one cavity 5 will flow into the other cavity 5, affecting the normal use of the equipment. Since the piping device 10 according to the embodiment of the present application is provided with the isolation section 4, if an internal leakage of the brazing material occurs, the brazing material can overflow from the isolation section 4 and leak to the outside, and the internal leakage will not flow into the adjacent cavity 5 and affect the performance of the air conditioning equipment.

[0081] Both the first laminated plate 11 and the second laminated plate 21 may be flat plates, which improves the uniformity of the flow of the solder layer 3 between the first laminated plate 11 and the second laminated plate 21 when melted, improves the welding fixing effect between the first laminated plate 11 and the second laminated plate 21, and simplifies the manufacturing process of the flat plates, which is advantageous for saving manufacturing costs.

[0082] Furthermore, the solder layer 3 avoids the cavity 5, thereby preventing the solder layer 3 from entering the cavity 5 and affecting the flow rate of the coolant in the cavity 5, and also preventing the solder layer 3 from contaminating the coolant in the cavity 5.

[0083] 1 to 4, the first recessed portion 12 includes a first recessed cavity 121 and a first recessed groove 122, the second recessed portion 22 includes a second recessed cavity 221 and a second recessed groove 222, the second recessed cavity 221 is combined with the first recessed cavity 121 to form a first cavity 51, and the second recessed groove 222 is combined with the first recessed groove 122 to form a second cavity 52. ​​As shown in FIG. 2, a first escape hole 31 and a second escape hole 32 are opened in the solder layer 3, the first escape hole 31 is used to avoid the first cavity 51, and the second escape hole 32 is used to avoid the second cavity 52. When the second cavity 52 is a through chamber along the straight line AB, the second escape hole 32 divides the solder layer 3 into two parts, one part located on one side of the second cavity 52 closer to the first cavity 51, and the other part located on one side of the second cavity 52 farther from the first cavity 51. The isolation portion 4 is located between the first cavity 51 and the second cavity 52, and the length of the isolation portion 4 is greater than the length of the first cavity 51; As a result, a line connecting any two points between the first cavity 51 and the second cavity 52 passes through the isolating portion 4, thus ensuring that the isolating portion 4 can completely cover the area between the first cavity 51 and the second cavity 52, and when any position of one of the first and second cavities 51 and 52 causes internal leakage to the other cavity 5, the isolating portion 4 can accurately detect the internal leakage phenomenon, thereby improving the use safety of the piping device 10. As shown in Figures 1 and 2, the "length" referred to here refers to the size in the direction parallel to the straight line AB.

[0084] In some other embodiments of the present application, the isolation portion 4 is a short segment, and as shown in Figures 11 and 12, it is sufficient to provide the isolation portion 4 only at one end where the first cavity 51 and the second cavity 52 approach each other, and since there is a small risk of internal leakage in the area where the isolation portion 4 is not provided in the two adjacent cavities 5 in the arrangement path of the isolation portion 4, it is not necessary to provide the isolation portion 4 in that area.

[0085] The piping device 10 according to the embodiment of the present application is provided with an isolation portion 4, which can accurately detect whether internal leakage occurs between two adjacent cavities 5. As a result, when the flow paths in the two adjacent cavities 5 are penetrated due to a welding defect, internal leakage will not occur, and the performance of the cooling equipment will not be affected by the internal leakage flowing into the adjacent cavities 5. When detecting internal leakage in the piping device 10, the leakage detection can be completed at the same time as the internal leakage, and it is also possible to ensure that there is no need to detect the flow paths of each cavity 5 individually. This greatly improves the leakage detection efficiency of the piping device 10, and makes it easier to determine the location of internal leakage during subsequent maintenance.

[0086] In some embodiments of the present application, the isolation portion 4 between two adjacent cavities 5 includes a first isolation portion and a second isolation portion, the first isolation portion is opened in the first laminated plate 11 and penetrates the first laminated plate 11 in the thickness direction (i.e., MN direction) of the first laminated plate 11, the second isolation portion is opened in the second laminated plate 21 and penetrates the second laminated plate 21 in the thickness direction (i.e., MN direction) of the second laminated plate 21, and the first isolation portion and the second isolation portion have the same arrangement path, that is, the arrangement path of the first isolation portion and the arrangement path of the second isolation portion are both the same as the arrangement path of the isolation portion 4. As shown in Figures 1 and 2, the arrangement paths of the first isolation portion and the second isolation portion both extend along the straight line AB direction. In other words, the first isolation portion and the second isolation portion together constitute isolation portion 4, and the distance between a point in each of the first isolation portion and the second isolation portion that is closest to end A and a point in each of the first isolation portion and the second isolation portion that is closest to end B is the length of isolation portion 4. As shown in FIG. 1, the size of piping device 10 along the line AB is the length of isolation portion 4.

[0087] In some embodiments of the present application, as shown in Figures 3 to 5, the first isolation portion may include a plurality of intermittent first seams 41, the first seams 41 being long strip-shaped slits, and the longitudinal direction of the first seams 41 extending along the direction of the straight line AB, the plurality of first seams 41 being spaced apart along the direction of the straight line AB, and a first partition portion 13 being between two adjacent first seams 41, thus ensuring that the first cover body 1 has good strength, and the first isolation portion does not excessively weaken the strength of the first cover body 1, and at the same time, the structure of the first isolation portion is simple and easy to process. Similarly, the second isolation portion may include a plurality of intermittent second seams 42, the second seams 42 being long strip-shaped slits, and the longitudinal direction of the second seams 42 extending along the direction of the straight line AB, the plurality of second seams 42 being spaced apart along the direction of the straight line AB, and a second partition portion 23 being between two adjacent second seams 42; thus, it is possible to ensure that the second cover body 2 has good strength, and the second isolation portion does not excessively weaken the strength of the second cover body 2; and at the same time, the structure of the second isolation portion is simple and easy to process.

[0088] As shown in Fig. 5, in the first direction, that is, in the direction of the straight line MN, the first partition 13 between two adjacent first seams 41 is aligned with the second seam 42, and the length of the second seam 42 is equal to or greater than the length of the first partition 13, and the second partition 23 between two adjacent second seams 42 is aligned with the first seam 41, and the length of the first seam 41 is equal to or greater than the length of the second partition 23. In the specific example shown in Fig. 5, the length of the first seam 41 is L1, the length of the second seam 42 is L2, the length of the first partition 13 is L3, and the length of the second partition 23 is L4, where L1 and L4 satisfy the relationship: L1 ≧ L4, and L2 and L3 satisfy the relationship: L2 ≧ L3. In this way, it is possible to ensure that the isolation section 4 is completely covered between two adjacent cavities 5, there is no blind spot for internal leakage detection, and any position of one cavity 5 is connected to another cavity 5. When an internal leakage occurs, the refrigerant caused by the internal leakage can overflow from the isolation section 4, which makes it easy for the user to quickly identify the location of the internal leakage.

[0089] 1-2 and 5, in a first direction, i.e., in the direction of the straight line MN, each first seam 41 is aligned with a part of an adjacent second seam 42, and each first seam 41 is offset from another part of the adjacent second seam 42. Similarly, each second seam 42 is aligned with a part of an adjacent first seam 41, and each second seam 42 is offset from another part of the adjacent first seam 41. In this way, there are isolation portions 4 in all directions along the straight line AB, and there are no blind spots for internal leakage detection. In other words, the first joint 41 and the second joint 42 are offset from each other, and the first joint 41 and the second joint 42 have a certain crossing distance in the length direction, so that when the flow paths in two adjacent cavities 5 are penetrated due to brazing welding defects to cause internal leakage, the first joint 41 or the second joint 42 will not leak to the outside, and the internal leakage will not flow into the adjacent cavities 5, thereby affecting the performance of the cooling equipment. In this way, it is possible to avoid the case where there is a blind spot for internal leakage detection when the first joint 41 does not cross the second joint 42, for example, internal leakage may occur at the position of the blind spot for internal leakage detection.

[0090] In some embodiments of the present application, the alignment length of each first seam 41 and adjacent second seam 42 does not exceed 1 / 2 the length of the first seam 41 and does not exceed 1 / 2 the length of the second seam 42. The alignment length of each first seam 41 and adjacent second seam 42 is L5, where L1 and L5 satisfy the relationship: L5≦L1 / 2, and L2 and L5 satisfy the relationship: L5≦L2 / 2. This makes it possible to prevent the first seam 41 and the second seam 42 from being too long, which would excessively weaken the strength of the first cover 1 and the second cover 2.

[0091] In some embodiments of the present application, the alignment length of each first seam 41 and the adjacent second seam 42 is 1 / 6 or more of the length of the first seam 41 and 1 / 6 or more of the length of the second seam 42. The alignment length of each first seam 41 and the adjacent second seam 42 is L5, where L1 and L5 satisfy the relationship: L5≧L1 / 6, and L2 and L5 satisfy the relationship: L5≧L2 / 6. This ensures the detection continuity between the first seam 41 and the adjacent second seam 42, and there is no blind spot for internal leakage detection.

[0092] In some embodiments of the present application, the lengths of the first seams 41 are equal, and the distance between any two adjacent first seams 41 is equal, and the lengths of the second seams 42 are equal, and the distance between any two adjacent second seams 42 is equal. In other words, referring to FIG. 5, the lengths of the first seams 41 are all L1, the lengths of the first partitions 13 between any two adjacent first seams 41 are all L3, the lengths of the second seams 42 are all L2, and the lengths of the second partitions 23 between any two adjacent second seams 42 are all L4. Thus, the intervals between the first seams 41 and the second seams 42 are uniform, which is easy to process and is favorable for simplifying the processing process, and is therefore favorable for saving manufacturing costs.

[0093] In some embodiments of the present application, the first seam 41 and the second seam 42 can be configured as arc-shaped slits, and the multiple first seams 41 and the multiple second seams 42 are all arranged along the same arc-shaped path.

[0094] In some embodiments of the present application, the solder layer 3 fills the area between the first laminated plate 11 and the second laminated plate 21 except for the cavity 5. As shown in Fig. 2, the solder layer 3 not only provides the first escape hole 31 and the second escape hole 32, but also fills the other areas between the first laminated plate 11 and the second laminated plate 21. In this way, when the solder layer 3 melts, it can sufficiently fill the area between the first laminated plate 11 and the second laminated plate 21 except for the cavity 5, thereby reducing the risk of internal leakage.

[0095] In some embodiments of the present application, the material of the first cover 1 and the second cover 2 includes iron. It can be understood that the main material of the first cover 1 and the second cover 2 includes iron, and may include other materials such as carbon, so that the first cover 1 and the second cover 2 are steel covers, and optionally, the material of the first cover 1 and the second cover 2 is stainless steel, that is, the first cover 1 and the second cover 2 are stainless steel covers. Of course, in some embodiments, the first cover 1 and the second cover 2 may be pure iron covers. Compared with purple copper and copper, iron has high strength and low cost, which is advantageous for reducing the overall cost of the piping device 10.

[0096] The piping device 10 according to the embodiment of the third aspect of the present invention will be described in detail below with reference to a combination of Figs. 1 to 10.

[0097] As shown in Fig. 1, 7 to 8, a piping device 10 according to an embodiment of the third aspect of the present application can include a first cover 1 and a second cover 2, the first cover 1 has a first laminated plate 11, the second cover 2 has a second laminated plate 21, the first laminated plate 11 and the second laminated plate 21 are laminated face to face to form at least one cavity 5 and at least one isolation part 4, the cavity 5 is used for the flow of a refrigerant, the at least one isolation part 4 is located on at least one side in the circumferential direction of the corresponding at least one cavity 5, and the arrangement path of the isolation part 4 is laterally opposite to the extension path of the corresponding cavity 5. For example, in the example shown in Fig. 1, 7 to 8, the cavity 5 includes a first cavity 51, and the isolation part 4 is provided on one side in the circumferential direction of the first cavity 51. When a first cavity 51 leaks internally into another cavity 5, or when another cavity 5 leaks into the first cavity 51, the liquid caused by the internal leakage will overflow from the isolation portion 4 on one side of the first cavity 51.

[0098] As shown in Figures 3 to 5, each isolation section 4 includes a plurality of first joints 41 and a plurality of first partition sections 13 that are alternately provided through the first laminated plate 11, and a plurality of second joints 42 and a plurality of second partition sections 23 that are alternately provided through the second laminated plate 21. Specifically, the first joint 41 is opened in the first laminated plate 11, the first joint 41 penetrates the first laminated plate 11 in the thickness direction of the first laminated plate 11 (i.e., the MN direction), the second joint 42 is opened in the second laminated plate 21, the second joint 42 penetrates the second laminated plate 21 in the thickness direction of the second laminated plate 21 (i.e., the MN direction), and the first joint 41 and the second joint 42 have the same arrangement path, that is, the arrangement path of the first joint 41 and the arrangement path of the second joint 42 are both the same as the arrangement path of the isolation section 4. The first seams 41 are multiple, and two adjacent first seams 41 are separated by a first partition 13, thus ensuring that the first cover 1 has good strength, and the first seams 41 do not excessively weaken the strength of the first cover 1, and at the same time, the structure of the first seams 41 is simple and easy to process. The first partition 13 is aligned with the second seam 42, and the length of the second seam 42 is equal to or longer than the length of the first partition 13. The second seams 42 are multiple, and two adjacent second seams 42 are separated by a second partition 23, thus ensuring that the second cover 2 has good strength, and the second partition does not excessively weaken the strength of the second cover 2, and at the same time, the structure of the second partition is simple and easy to process.

[0099] In some embodiments of the present application, as shown in Fig. 5, in a direction perpendicular to the bonding surface between the first laminated plate 11 and the second laminated plate 21, i.e., in the direction of a straight line MN, the first partition 13 faces the second seam 42, and the first seam 41 faces the second partition 23. For example, the first partition 13 is aligned with the second seam 42, and the second partition 23 is aligned with the first seam 41. When an internal leakage occurs at any position of the cavity 5 on one side where the isolating portion 4 is provided, the liquid caused by the internal leakage will overflow from the first seam 41 or the second seam 42, and the isolating portion 4 can accurately detect the internal leakage phenomenon, thereby improving the safety of the use of the piping device 10.

[0100] The piping device 10 according to the embodiment of the present application is provided with an isolation portion 4, thereby making it possible to accurately detect whether an internal leak occurs on the side of the cavity 5 where the isolation portion 4 is installed, thereby improving the safety of using the piping device 10.

[0101] In some embodiments of the present application, the length of the first seam 41 is equal to or greater than the length of the second partition 23, and the length of the second seam 42 is equal to or greater than the length of the first partition 13. For example, referring to the size relationship in FIG. 5, the length of the first seam 41 is L1, the length of the second seam 42 is L2, the length of the first partition 13 is L3, and the length of the second partition 23 is L4, where L1 and L4 satisfy the relationship: L1≧L4, and L2 and L3 satisfy the relationship: L2≧L3. In this way, it is possible to ensure that the isolation part 4 is completely covered on one side in the circumferential direction of the cavity 5, and there is no blind spot for detecting internal leakage. When an internal leakage occurs at any position of the cavity 5 on the one side where the isolation part 4 is provided, the refrigerant caused by the internal leakage can overflow from the isolation part 4, making it easy for the user to quickly identify the location of the internal leakage.

[0102] In some embodiments of the present application, as shown in Figures 5-6 and 8-10, along the direction perpendicular to the bonding surface between the first laminated plate 11 and the second laminated plate 21, i.e., in the direction of the straight line MN, each first seam 41 is aligned with a part of the adjacent second seam 42 and offset from another part. In other words, the first seam 41 and the second seam 42 are offset from each other, and the first seam 41 and the second seam 42 have a certain cross distance in the length direction, so there is no blind spot for detecting internal leakage, and when an internal leakage occurs at any position of the cavity 5 on one side where the isolation part 4 is provided, the refrigerant due to the internal leakage can overflow to the outside from the first seam 41 or the second seam 42, and it can be ensured that the internal leakage does not flow to the adjacent cavity 5 on the other side of the isolation part 4 and affect the performance of the cooling equipment.

[0103] In some embodiments of the present application, the alignment length of each first seam 41 and the adjacent second seam 42 does not exceed 1 / 2 the length of the first seam 41, and does not exceed 1 / 2 the length of the second seam 42. Referring to the size relationship in FIG. 5, the alignment length of each first seam 41 and the adjacent second seam 42 is L5, where L1 and L5 satisfy the relationship: L5≦L1 / 2, and L2 and L5 satisfy the relationship: L5≦L2 / 2. This can prevent the first seam 41 and the second seam 42 from being too long, which would excessively weaken the strength of the first cover 1 and the second cover 2.

[0104] In some embodiments of the present application, the alignment length of each first seam 41 and the adjacent second seam 42 is 1 / 6 or more of the length of the first seam 41 and 1 / 6 or more of the length of the second seam 42. Referring to the size relationship in FIG. 5, the alignment length of each first seam 41 and the adjacent second seam 42 is L5, where L1 and L5 satisfy the relationship: L5≧L1 / 6, and L2 and L5 satisfy the relationship: L5≧L2 / 6. This ensures the detection continuity between the first seam 41 and the adjacent second seam 42, and there is no blind spot for internal leakage detection.

[0105] In some embodiments of the present application, the first seams 41 are multiple, the lengths of the multiple first seams 41 are equal, and the distance between any two adjacent first seams 41 is equal; the second seams 42 are multiple, the lengths of the multiple second seams 42 are equal, and the distance between any two adjacent second seams 42 is equal. In other words, referring to FIG. 5, the length of the multiple first seams 41 is L1, the length of the first partition 13 between any two adjacent first seams 41 is L3, the length of the multiple second seams 42 is L2, and the length of the second partition 23 between any two adjacent second seams 42 is L4. Thus, the interval between the first seams 41 and the second seams 42 is uniform, which is easy to process and is favorable for simplifying the processing process, and is favorable for saving manufacturing costs.

[0106] In some embodiments of the present application, the first laminated plate 11 and the second laminated plate 21 are fixed by welding. For example, the first laminated plate 11 and the second laminated plate 21 can be fixed by welding with a solder layer 3. The solder layer 3 covers the area between the first laminated plate 11 and the second laminated plate 21 other than the cavity 5, reducing the risk of internal leakage. The solder layer 3 avoids the cavity 5, thereby preventing the solder layer 3 from entering the cavity 5 and affecting the flow rate of the coolant in the cavity 5, and also preventing the solder layer 3 from contaminating the coolant in the cavity 5.

[0107] The solder layer 3 may be a brazing material. When the first cover 1 and the second cover 2 need to be welded and fixed, the first cover 1, the second cover 2 and the solder layer 3 can be furnace brazed together, and the brazing material can be melted and flowed at high temperature to fill the gap between the first cover 1 and the second cover 2, and the weld fixing between the first cover 1 and the second cover 2 can be completed after the brazing material is cooled and solidified. If the flow of the brazing material is uneven, it is easy to cause internal leakage between the two adjacent cavities 5 between the first cover 1 and the second cover 2, and the refrigerant in one cavity 5 will flow into the other cavity 5, affecting the normal use of the equipment.

[0108] Optionally, both the first laminated plate 11 and the second laminated plate 21 may be flat plates, which improves the uniformity of the flow of the solder layer 3 between the first laminated plate 11 and the second laminated plate 21 when melted, improves the welding fixing effect between the first laminated plate 11 and the second laminated plate 21, and simplifies the manufacturing process of the flat plates, which is advantageous for saving manufacturing costs.

[0109] In some other embodiments of the present application, the first cover 1 and the second cover 2 are connected and fixed by fasteners such as bolts, rivets, etc.

[0110] In some embodiments of the present application, the material of the first cover 1 and the second cover 2 is stainless steel, that is, the first cover 1 and the second cover 2 are covers made of stainless steel. Compared with purple copper and copper, stainless steel has high strength and low cost, which is advantageous for reducing the overall cost of the piping device 10.

[0111] The piping device 10 according to the embodiment of the fourth aspect of the present invention will be described in detail below with reference to a combination of Figs. 6 to 10.

[0112] As shown in Figures 6 to 8, a piping device 10 according to an embodiment of the fourth aspect of the present application can include a first cover body 1 and a second cover body 2, the first cover body 1 has a first bonding plate 11, and the second cover body 2 has a second bonding plate 21, the first bonding plate 11 and the second bonding plate 21 face to face and are in close contact with each other to form a cavity 5 and an isolation portion 4, the cavity 5 is used for the flow of a refrigerant, and the isolation portion 4 is arranged to surround the outer periphery of the cavity 5. In this way, when the surrounded cavity 5 causes an internal leak into another cavity or another cavity leaks into the cavity 5, the liquid due to the internal leak overflows from the isolation portion 4 surrounding the cavity 5. As shown in FIG. 8, the cavity 5 includes a first cavity 51a, which is surrounded by a ring of isolation portion 4a, such that if the surrounded first cavity 51a develops an internal leak into the other cavities 5, or if the other cavities 5 develop an internal leak into the first cavity 51a, the liquid from the internal leak will overflow from the isolation portion 4a surrounding the first cavity 51a.

[0113] The isolation section 4 may include a plurality of first joints 41 and a plurality of second joints 42, the plurality of first joints 41 being provided through the first laminated plate 11 and structured to be spaced apart along the arrangement path of the isolation section 4, and the plurality of second joints 42 being provided through the second laminated plate 21 and structured to be spaced apart along the arrangement path of the isolation section 4. Specifically, the first joint 41 is opened in the first laminated plate 11, the first joint 41 penetrates the first laminated plate 11 in the thickness direction of the first laminated plate 11 (i.e., the MN direction), the second joint 42 is opened in the second laminated plate 21, the second joint 42 penetrates the second laminated plate 21 in the thickness direction of the second laminated plate 21 (i.e., the MN direction), and the first joint 41 and the second joint 42 have the same arrangement path, that is, the arrangement path of the first joint 41 and the arrangement path of the second joint 42 are both the same as the arrangement path of the isolation section 4.

[0114] In a planar projection parallel to the bonding surface of the first laminated plate 11 and the second laminated plate 21, i.e., in a plane perpendicular to the straight line MN, the multiple first joints 41 and the multiple second joints 42 are arranged alternately along the arrangement path of the isolation section 4, and both ends of the beginning and end of each first joint 41 overlap at least a portion of two adjacent second joints 42, and both ends of the beginning and end of each second joint 42 overlap at least a portion of two adjacent first joints 41. In other words, there is a certain intersection distance between the first joint 41 and the second joint 42 on the arrangement path of the isolation section 4, and thus, it is possible to avoid the case where there is a blind spot for internal leakage detection when the first joint 41 does not intersect with the second joint 42, that is, there is no blind spot for internal leakage detection, and when the surrounded first cavity 51a causes internal leakage into other cavities 5, or when other cavities 5 cause internal leakage into the first cavity 51a, the liquid caused by the internal leakage will overflow to the outside from the isolation section 4a surrounding the first cavity 51a, and will not flow into adjacent cavities 5 due to internal leakage, thereby affecting the performance of the cooling equipment.

[0115] The piping device 10 according to the embodiment of the present application can accurately detect whether an internal leak occurs in the cavity 5 by installing an isolation portion 4 surrounded by the outer periphery of the cavity 5, thereby improving the safety of using the piping device 10.

[0116] In some embodiments of the present application, the overlap length of each first seam 41 and the adjacent second seam 42 does not exceed 1 / 2 the length of the first seam 41, and does not exceed 1 / 2 the length of the second seam 42. Referring to the size relationship in FIG. 5, the alignment length of each first seam 41 and the adjacent second seam 42 is L5, where L1 and L5 satisfy the relationship: L5≦L1 / 2, and L2 and L5 satisfy the relationship: L5≦L2 / 2. This can prevent the first seam 41 and the second seam 42 from being too long, which would excessively weaken the strength of the first cover 1 and the second cover 2.

[0117] In some embodiments of the present application, the overlap length between each first seam 41 and the adjacent second seam 42 is 1 / 6 or more of the length of the first seam 41 and 1 / 6 or more of the length of the second seam 42. Referring to the size relationship in FIG. 5, the alignment length between each first seam 41 and the adjacent second seam 42 is L5, where L1 and L5 satisfy the relationship: L5≧L1 / 6, and L2 and L5 satisfy the relationship: L5≧L2 / 6. This ensures the detection continuity between the first seam 41 and the adjacent second seam 42, and there is no blind spot for internal leakage detection.

[0118] In some embodiments of the present application, the lengths of the first seams 41 are equal, and the distance between any two adjacent first seams 41 is equal, and the lengths of the second seams 42 are equal, and the distance between any two adjacent second seams 42 is equal. In other words, referring to FIG. 5, the lengths of the first seams 41 are all L1, the lengths of the first partitions 13 between any two adjacent first seams 41 are all L3, the lengths of the second seams 42 are all L2, and the lengths of the second partitions 23 between any two adjacent second seams 42 are all L4, thus making it possible to make the intervals between the first seams 41 and the second seams 42 uniform, which is easy to process and is favorable for simplifying the processing process, and is therefore favorable for saving manufacturing costs.

[0119] In some embodiments of the present application, the first laminated plate 11 and the second laminated plate 21 are fixed by welding. For example, the first laminated plate 11 and the second laminated plate 21 can be fixed by welding with a solder layer 3. The solder layer 3 covers the area between the first laminated plate 11 and the second laminated plate 21 other than the cavity 5, reducing the risk of internal leakage. The solder layer 3 avoids the cavity 5, thereby preventing the solder layer 3 from entering the cavity 5 and affecting the flow rate of the coolant in the cavity 5, and also preventing the solder layer 3 from contaminating the coolant in the cavity 5.

[0120] The solder layer 3 may be a brazing material. When the first cover 1 and the second cover 2 need to be welded and fixed, the first cover 1, the second cover 2 and the solder layer 3 can be furnace brazed together, and the brazing material can be melted and flowed at high temperature to fill the gap between the first cover 1 and the second cover 2, and the weld fixing between the first cover 1 and the second cover 2 can be completed after the brazing material is cooled and solidified. If the flow of the brazing material is uneven, it is easy to cause internal leakage between the two adjacent cavities 5 between the first cover 1 and the second cover 2, and the refrigerant in one cavity 5 will flow into the other cavity 5, affecting the normal use of the equipment.

[0121] Optionally, both the first laminated plate 11 and the second laminated plate 21 may be flat plates, which improves the uniformity of the flow of the solder layer 3 between the first laminated plate 11 and the second laminated plate 21 when melted, improves the welding fixing effect between the first laminated plate 11 and the second laminated plate 21, and simplifies the manufacturing process of the flat plates, which is advantageous for saving manufacturing costs.

[0122] In some other embodiments of the present application, the first cover 1 and the second cover 2 are connected and fixed by fasteners such as bolts, rivets, etc.

[0123] In some embodiments of the present application, the material of the first cover 1 and the second cover 2 is stainless steel, that is, the first cover 1 and the second cover 2 are covers made of stainless steel. Compared with purple copper and copper, stainless steel has high strength and low cost, which is advantageous for reducing the overall cost of the piping device 10.

[0124] A cooling system according to an embodiment of the fifth aspect of the present application includes the piping device 10 of the above embodiment. The cooling system may be a cooling system of an air conditioner, a cooling system of a refrigerator, or other cooling system of equipment having a cooling function.
