[0036] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0037] The inventors have found that in the joint of the connecting pipeline, the structure of sealing by squeezing the seal to produce deformation, the seal produces a large deformation, and maintaining a large deformation for a long time is easy to crush the seal ring, which is easy to cause seal failure. When repairing the pipeline, the crushed seal needs to be replaced. If the crushed seal is still used, the risk of heat exchange medium leakage is greatly increased. The embodiment of the present application provides a pipeline butt joint structure, a hydraulic module and a heat pump system, which can effectively improve the sealing effect of the pipeline butt joint structure.

[0038] The pipe connection structure 10 of the embodiment of the present application can be applied to a hydraulic module and connected to a functional device 20 of the hydraulic module, such as Figure 1 As shown in FIG. 1 , it is a schematic diagram of a structure in which a pipeline docking structure 10 of an embodiment of the present application is installed on a functional device 20. When the pipeline docking structure 10 of the embodiment of the present application is applied to a hydraulic module, the hydraulic module includes a plurality of functional devices 20, such as Figure 2 As shown, multiple functional devices 20 of the hydraulic module are installed in the internal space of the hydraulic module box, and at least one functional device 20 is connected to one of the docking pipes 100 of the pipeline docking structure 10, such as Figure 3 As shown, the functional device 20 of the hydraulic module includes at least one of a liquid storage tank 21, an expansion tank 22, a heat exchange device 23 and a water pump 24.

[0039] like Figure 4 As shown, the pipeline docking structure 10 includes a seal 200 and two sections of docking pipes 100, each of which has a sub-flow channel 101 inside. Figure 5 As shown, one of the butt-joint tubes 100 is installed on the other butt-joint tube 100 to connect the two sections of the butt-joint tubes 100 in alignment, and the sub-channels 101 of the two sections of the butt-joint tubes 100 are connected to form a guide channel 103, and the heat exchange medium flows in the guide channel 103 to be transmitted between the structural parts connected to the two sections of the butt-joint tubes 100.

[0040] For example, see Figure 3, the water pump 24 includes an inlet pipe 241 and an outlet pipe 242, and the number of the pipeline docking structures 10 connected to the water pump 24 is two groups, one of the docking pipes 100 of one group of the pipeline docking structures 10 forms the inlet pipe 241, and the other docking pipe 100 of the pipeline docking structure 10 is connected to the liquid storage tank 21, and one of the docking pipes 100 of the other group of the pipeline docking structures 10 forms the outlet pipe 242, and the other docking pipe 100 of the pipeline docking structure 10 is connected to the external water delivery structure, and the water pump 24 operates to transport the heat exchange medium in the liquid storage tank 21 to the external water delivery structure. Optionally, the water pump 24 includes a centrifugal water pump, an axial flow water pump, etc. The above is only an exemplary introduction. In some other embodiments, a group of pipeline docking structures 10 can be set at the structure where the heat exchange medium inlet and the heat exchange medium outlet of the liquid storage tank 21, the expansion tank 22, the heat exchange device 23 and other devices need to be connected by pipelines, and the specific selection can be made according to actual needs.

[0041] like Figure 5 As shown, the two sections of the butt-jointed tubes 100 are butt-jointed and define a sealed cavity 102. The sealed cavity 102 is arranged around the periphery of the guide channel 103 and is spaced apart from the guide channel 103. The seal 200 is arranged in the sealed cavity 102, and the outer surfaces of the seal 200 are respectively in contact with the wall surfaces of the two sections of the butt-jointed tubes 100. In this way, a separate sealed cavity 102 is planned for installing the seal 200. The two sections of the butt-jointed tubes 100 are assembled in place to define the sealed cavity 102. After the two sections of the butt-jointed tubes 100 are assembled in place, they act on the seal 200. The seal 200 is deformed in the sealed cavity 102 and achieves sealing. There is no need to rely on the seal 200 to produce a large deformation to achieve a sealing effect. Compared with the related art, in which the seal 200 is directly set between the two structures and the sealing effect is estimated by estimating the deformation of the seal 200, the sealing effect at the pipeline docking structure 10 of the embodiment of the present application is more reliable, the deformation of the seal 200 is small, and after disassembly and maintenance, the seal 200 can still be installed in the sealing cavity 102, and the seal 200 can still play a good sealing effect. In addition, the two sections of the butt-joint pipe 100 restrict the seal 200 in the sealing cavity 102, which can control the deformation area of ​​the seal 200, thereby preventing the seal 200 from having a large deformation, and preventing the seal 200 from being in a deformed state for a long time and being crushed to reduce the sealing effect.

[0042] like Figure 6As shown, at least one of the two butt-joint pipes 100 has a sealing groove 104. When the two butt-joint pipes 100 are separated, the sealing member 200 can be pre-installed in the sealing groove 104 to initially limit the position of the sealing member 200. When the two butt-joint pipes 100 are brought close to each other and installed in place, the sealing groove 104 participates in forming the sealing cavity 102, that is, the sealing groove 104 can be a part of the sealing cavity 102. By setting the sealing groove 104 to limit the position of the sealing member 200, the sealing member 200 is prevented from moving at will, which is convenient for installation and helps to improve the efficiency of alignment and assembly.

[0043] like Figure 6 As shown, the butt joint pipe 100 has a butt joint surface 10, and the sub-flow channel 101 extends to the butt joint surface 10. The butt joint surfaces 10 of the two butt joint pipes 100 are arranged facing each other, and at least part of the butt joint surfaces 10 of the two butt joint pipes 100 are arranged in contact with each other. Specifically, the butt joint surface 10 has a butt joint area 112, and the butt joint area 112 of the butt joint surface 10 is arranged in contact with the area opposite to it. After disassembly and overhaul, the butt joint surfaces 10 of the two butt joint pipes 100 are brought close to each other. When the butt joint area 112 of the butt joint surface 10 is in contact with the area opposite to it, and the relative positions of the two butt joint pipes 100 are fixed, it means that the two butt joint pipes 100 are assembled in place, and the two butt joint pipes 100 define a sealing cavity 102. The sealing member 200 is placed in the sealing cavity 102 and abutted by the two butt joint pipes 100 to achieve sealing.

[0044] At least one of the two mating surfaces 10 has a groove area 111 , and the groove area 111 and the mating surface 10 opposite thereto define a sealing cavity 102 , and the groove area 111 is provided with the sealing groove 104 as described above. Optionally, at least one of the two docking surfaces 10 has both a groove area 111 and a docking area 112, and the groove area 111 is recessed relative to the docking area 112 to form a sealing groove 104. For example, one of the docking surfaces 10 has the groove area 111 and the docking area 112, and the other docking surface 10 has only the docking area 112. The docking areas 112 of the two docking surfaces 10 fit together, and the groove area 111 of one of the docking surfaces 10 is spaced apart from a portion of the docking area 112 of the other docking surface 10 to define a sealing cavity 102; or, both of the two docking surfaces 10 have the groove area 111 and the docking area 112, the docking areas 112 of the two docking surfaces 10 fit together, and the groove areas 111 of the two docking surfaces 10 are arranged relative to each other, and the docking areas 112 jointly define a sealing cavity 102.

[0045] Of course, in some other embodiments, such as Figure 7As shown, it is also possible to set one of the docking surfaces 10 to have only the groove area 111, and the other docking surface 10 to have the groove area 111 and the docking area 112, wherein the edge of the groove area 111 of one docking surface 10 contacts the docking area 112 of the other docking surface 10, and the groove areas 111 of the two docking surfaces 10 jointly define the sealed cavity 102. Alternatively, each docking surface 10 has only the groove area 111, and the edge areas of the groove areas 111 of the two docking surfaces 10 contact, and the two groove areas 111 jointly define the sealed cavity 102.

[0046] Among them, the docking area 112 is a plane or a convex arc surface, etc. The embodiment of the present application does not limit the surface shape of the docking area 112, and it can be selected according to the requirements of the embodiment. Any surface shape that can enable the two docking tubes 100 to be stably connected after docking is suitable for this application.

[0047] like Figure 6 and Figure 7 As shown, the docking surface 10 has an inner docking edge 1111, and the inner docking edge 1111 defines a first opening of the sub-flow channel 101. After the two sections of the docking tube 100 are docked, the first openings of the sub-flow channels 101 of the two sections of the docking tube 100 are connected to each other to connect the two sections of the sub-flow channels 101 and form a guide channel 103.

[0048] Optionally, the groove area 111 extends to the abutment inner edge 1111, for example Figure 7 As shown, when the same docking surface 10 only has a groove area 111, the inner edge of the groove area 111 forms a docking inner edge 1111, and the outer edge of the groove area 111 forms a docking outer edge, and the docking inner edge 1111 and the docking outer edge of the docking surface 10 having the groove area 111 are in contact with another docking surface 10; or, when the same docking surface 10 has a groove area 111 and a docking area 112, the inner edge of the groove area 111 forms a docking inner edge 1111, the outer edge of the groove area 111 is connected to the docking area 112, the outer edge of the docking area 112 forms a docking outer edge, and the docking area 112 is in contact with another docking surface 10.

[0049] Optionally, the groove area 111 is spaced apart from the butt inner edge 1111. In this case, the same butt joint surface 10 has the groove area 111 and the butt joint area 112, the inner edge of the butt joint area 112 forms the butt joint inner edge 1111, and the outer edge of the butt joint area 112 forms the butt joint outer edge. The inner edge of the groove area 111 is spaced apart from the butt joint inner edge 1111, and the outer edge of the groove area 111 extends to the butt joint outer edge; or the inner edge of the groove area 111 is spaced apart from the butt joint inner edge 1111, and the outer edge of the groove area 111 is spaced apart from the butt joint outer edge.

[0050] Optionally, two sections of butt joint pipes 100 are sleeved and installed. Specifically, one of the two sections of butt joint pipes 100 is a first butt joint pipe 110, and the other is a second butt joint pipe 120. Figure 8 As shown, the first butt joint tube 110 has a butt joint groove 121, and the sub-flow channel 101 of the first butt joint tube 110 extends to the groove bottom wall surface 1211 of the butt joint groove 121, and the groove bottom wall surface 1211 of the butt joint groove 121 forms the butt joint surface 10 of the first butt joint tube 110. The end of the second butt joint tube 120 is arranged in the butt joint groove 121, and has an end wall surface 1213 facing the groove bottom wall surface 1211 of the butt joint groove 121, and the sub-flow channel 101 of the second butt joint tube 120 extends to the end wall surface 1213, and the end wall surface 1213 forms the butt joint surface 10 of the second butt joint tube 120. In this way, the first docking tube 110 is sleeved on the outer periphery of the second docking tube 120 to facilitate quick alignment and assembly, and the end of the second docking tube 120 extends into the docking groove 121 of the first docking tube 110, and the docking surface 10 of the first docking tube 110 contacts the docking surface 10 of the second docking tube 120, and after the relative positions of the first docking tube 110 and the second docking tube 120 are fixed, the sealing cavity 102 is defined, and the first docking tube 110 and the second docking tube 120 are both in contact with the seal 200 to form a good sealing structure.

[0051] The second butt joint tube 120 has an outer peripheral wall surface, which is connected to the end wall surface 1213 of the second butt joint tube 120 and is arranged at an angle, and at least one of the groove bottom wall surface 1211 of the first butt joint tube 110, the end wall surface 1213 of the second butt joint tube 120, and the outer peripheral wall surface of the second butt joint tube 120 has a sealing groove 104. When the outer peripheral wall surface of the second butt joint tube 120 has a sealing groove 104, the wall surface of the second butt joint tube 120 defining the sealing groove 104 and the groove side wall surface 1212 of the butt joint groove 121 jointly define the sealing cavity 102.

[0052] Optionally, the outer peripheral wall surface of the end of the second butt joint pipe 120 and the groove side wall surface 1212 of the butt joint groove 121 are both threaded surfaces, and the second butt joint pipe 120 is threadedly connected to the first butt joint pipe 110 for easy assembly. In this case, at least one of the groove bottom wall surface 1211 of the first butt joint pipe 110 and the end wall surface 1213 of the second butt joint pipe 120 is provided with a sealing groove 104; or, the outer peripheral wall surface of the second butt joint pipe 120 is provided with a sealing groove 104, and the sealing groove 104 is spaced apart from the threaded surface, and further, in the direction of the end wall surface 1213 of the second butt joint pipe 120 toward the groove bottom wall surface 1211 of the first butt joint pipe 110, the distance from the sealing groove 104 of the second butt joint pipe 120 to the butt joint surface 10 is less than the distance from the threaded surface to the butt joint surface 10.

[0053] like Figure 8As shown, the sealing cavity 102 is a contoured cavity similar in shape to the sealing member 200, and the two sections of the butt-joint tubes 100 limit the wall of the sealing cavity 102 to fit with the wall of the sealing member 200, thereby increasing the contact area between the two sections of the butt-joint tubes 100 and the sealing member 200, and limiting the position of the sealing member 200 by the sealing cavity 102, thereby preventing the sealing member 200 from being deformed and partially squeezed out of the sealing cavity 102 under the extrusion of the two butt-joint tubes 100, so that effective sealing can be performed without the sealing member 200 undergoing a large amount of deformation.

[0054] The seal 200 is sleeved on the outer periphery of the flow guide channel 103, the seal 200 has a central axis H, the flow guide channel 103 has a transition flow section 105 passing through the seal 200, and the flow direction of the fluid passing through the transition flow section 105 is parallel to the direction where the central axis H of the seal 200 is located. Further, the seal 200 and the transition flow section 105 are coaxially arranged. The openings of the sub-flow channels 101 of the two butt-joint pipes 100 are located in the area where the transition flow section 105 is located. For example, please refer to Figure 5 The transition section 105 is formed by connecting a portion of the sub-channel 101 of one section of the butt-joint tube 100 with a portion of the sub-channel 101 of the other section of the butt-joint tube 100. At this time, the openings of the sub-channels 101 of the two sections of the butt-joint tubes 100 are located in the middle area of ​​the transition section 105; or, the transition section 105 is entirely formed by a portion of the sub-channel 101 of one section of the butt-joint tube 100. At this time, the openings of the sub-channels 101 of the two sections of the butt-joint tubes 100 are located at the edge of the transition section 105.

[0055] like Figure 8 As shown, the seal 200 has a plurality of sealing flanges 210, and each sealing flange 210 is arranged around the central axis H of the seal 200. When the two sections of the butt tube 100 act on the seal 200, each sealing flange 210 is deformed. Compared with the method of using a flat gasket to squeeze the entire plane of the seal 200 to deform the seal 200, by providing a plurality of sealing flanges 210, the deformation amount is dispersed, and the deformation amount of a single sealing flange 210 is smaller than the deformation amount of the entire seal 200, thereby improving the aging resistance of the seal 200.

[0056] Optionally, two adjacent sealing flanges 210 are connected; or, as Figure 8 As shown, two adjacent sealing flanges 210 are spaced apart, and the seal 200 also includes a sealing surface 220 disposed between the two adjacent sealing flanges 210 , the sealing surface 220 is connected to the surface of the sealing flange 210 , and both the surface of the sealing flange 210 and the sealing surface 220 are connected to the docking surface 10 of the docking pipe 100 .

[0057] The sealing flange 210 protrudes in the direction of the central axis H of the seal 200, or the sealing flange 210 protrudes in a direction perpendicular to the central axis H of the seal 200, so that the sealing flange 210 deforms in its protruding direction to achieve good sealing. Further, a part of the sealing flange 210 protrudes in one direction, and another part of the sealing flange 210 protrudes in another direction. Further, multiple sealing flanges 210 are arranged opposite to each other in groups of two, and the two sealing flanges 210 in each group are arranged opposite to each other in the direction of the central axis H of the seal 200, and protrude in directions away from each other. Multiple sealing flanges 210 protruding toward the same side are on the same sealing transition surface. In the protruding direction of the sealing flange 210, the distance from the surface of the sealing flange 210 to the sealing transition surface is the height of the sealing flange 210, and the heights of the multiple sealing flanges 210 are equal. The sealing transition surface may be the plane where the sealing surface 220 as described above is located. The sealing transition surface may be a plane or an arcuate surface. When the sealing transition surface is an arcuate surface, the curvature of the sealing transition surface is smaller than the curvature of the sealing transition surface.

[0058] like Figure 8 As shown, when at least one of the butt joint surface 10 of the first butt joint tube 110 and the butt joint surface 10 of the second butt joint tube 120 has a sealing groove 104, the sealing flange 210 protrudes in the direction of the central axis H of the seal 200, so that the sealing flange 210 deforms in the direction of the central axis H of the seal 200 to achieve good sealing. A sealing surface 220 is provided between two adjacent sealing protrusions protruding toward the same side, and in the direction of the central axis H of the seal 200, the maximum distance from the surface of the sealing flange 210 to the sealing surface 220 is the height of the sealing flange 210. For example, Figure 8 As shown, the seal 200 has four sealing flanges 210 and two sealing surfaces 220 . The four sealing flanges 210 are divided into two groups. Each sealing surface 220 is connected to two sealing flanges 210 protruding toward the same side. The sealing surface 220 is a plane perpendicular to the central axis H of the seal 200 .

[0059] The seal 200 of the embodiment of the present application is an elastic seal 200, so that the seal 200 can better adapt to the shape of the sealed cavity 102 and fit closely with the wall of the sealed cavity 102. Optionally, the seal 200 is a silicone seal, a foam seal, a rubber seal, etc.

[0060] The embodiment of the present application also provides a hydraulic module, which includes a box body, multiple functional devices 20 and the pipeline docking structure 10 as described above. The multiple functional devices 20 are all arranged in the internal space of the box body. The hydraulic module includes at least one group of pipeline docking structures 10, wherein at least one functional device 20 is connected to the pipeline docking structure 10, wherein the pipeline docking structure 10 is used to conduct two functional devices 20 connected thereto, or the pipeline docking structure 10 is used to conduct the functional device 20 connected thereto with an external structure to form a smooth medium transmission channel, and the medium transmission channel formed by adopting the pipeline docking structure 10 of the present application has a good sealing effect and good structural stability.

[0061] The embodiment of the present application further provides a heat pump system, the heat pump system comprising the above-mentioned hydraulic module. The hydraulic module has been introduced in the above-mentioned embodiment and will not be described in detail here.

[0062] It should be noted that the heat pump system provided in this embodiment should also include other modules or components that enable the heat pump system to operate normally, which are not introduced one by one here.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
