[0041] 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.

[0042] HVAC equipment can reduce the number of pipelines and reduce the cost of pipelines by using pipeline integration modules to realize integrated pipelines, while facilitating pipeline reversal and reducing the installation space occupied by the pipeline structure. Among them, in the case of multiple reversals of the fluid, the flow resistance of the fluid flow in the integrated pipeline is relatively large, which has a great impact on the connecting pipelines and the pipeline integration module, resulting in a large pressure loss in the pipeline system and prone to generate large noise. Based on this, the embodiment of the present application provides a pipeline integration module, an outdoor unit and HVAC equipment.

[0043] like Figures 1 to 3 , which is a schematic structural diagram of a pipeline integration module 10 provided in an embodiment of the present application. The pipeline integration module 10 includes a module body 100 and a first butt joint pipe 200 .

[0044] like Figure 3As shown, the module body 100 has a housing chamber 20 inside, and the housing chamber 20 is used to accommodate fluid, for example, the fluid includes a cold medium that can perform heat exchange, etc. A first opening 23 is provided on the outer surface of the module body 100, and the fluid can enter and exit the housing chamber 20 at the first opening 23. Specifically, the housing chamber 20 has a first flow segment 21, and the outer surface of the module body 100 is provided with a first opening 23 that is connected to the first flow segment 21. The opening direction of the first opening 23 is at an angle to the flow direction of the first flow segment 21, and the fluid can be reversed in the area between the first opening 23 and the first flow segment 21, for example, the fluid passing through the first opening 23 reverses and flows to other areas of the housing chamber 20 through the first flow segment 21, or the fluid in the housing chamber 20 reverses after passing through the first flow segment 21 and flows out of the housing chamber 20 from the first opening 23. When the fluid changes direction in the area between the first opening 23 and the first flow section 21 , it has a large flow resistance, which produces a large impact force on the wall surface of the module body 100 that defines the accommodating cavity 20 and generates noise. Frequent and long-term impacts will cause damage to the module body 100.

[0045] like Figure 3 and Figure 4 As shown, in the embodiment of the present application, the first butt-joint pipe 200 includes a first pipe section 210 and a second pipe section 220 arranged at an angle, the first pipe section 210 extends into the first flow section 21, and the first pipe section 210 is connected to the wall surface of the module body 100 defining the first flow section 21, and the second pipe section 220 is penetrated by the first opening 23, and the second pipe section 220 is connected to the wall surface of the module body 100 defining the first opening 23. In this way, the fluid can enter and exit the accommodating chamber 20 through the first butt-joint pipe 200, and when the fluid passes through the first butt-joint pipe 200, it gradually changes direction under the guidance of the first butt-joint pipe 200, reducing the flow domain that increases the flow resistance such as turbulence formed when the fluid suddenly changes direction at the first flow section 21, thereby effectively reducing the flow resistance of the fluid entering and exiting the accommodating chamber 20, and reducing the impact force of the fluid on the module body 100. In addition, by designing the size of the angle between the first pipe section 210 and the second pipe section 220, the turbulence of the fluid switching in the first butt joint 200 can also be pre-designed to reduce the flow resistance of the fluid in the first butt joint 200, and to regulate the flow direction and flow rate of the fluid in and out of the first butt joint 200, so that the fluid can flow more smoothly from the first butt joint 200 to the accommodating chamber 20, or, the fluid in other areas of the accommodating chamber 20 can enter the first butt joint 200 more smoothly.

[0046] Optionally, the first butt joint pipe 200 also includes a transition pipe section 230 connected between the first pipe section 210 and the second pipe section 220. The transition pipe section 230 is used to guide the fluid to flow more smoothly between the first pipe section 210 and the second pipe section 220. For example, the transition pipe section 230 can be a straight pipe or an arc-shaped pipe.

[0047] Wherein, when the fluid flows in various places of the internal flow channel of the cavity or the pipeline, it has a flow direction and a flow area, and the flow area is the area of ​​the cross section of the cavity or the internal flow channel perpendicular to the flow direction of the fluid. Optionally, the flow area of ​​the first pipe segment 210 is equal to the flow area of ​​the second pipe segment 220, and correspondingly, the flow area of ​​the transition pipe segment 230 is equal to the flow area of ​​the first pipe segment 210 and the flow area of ​​the second pipe segment 220. In some other embodiments, the flow area of ​​the first pipe segment 210 and the flow area of ​​the second pipe segment 220 may also be unequal, for example, the flow area of ​​the first pipe segment 210 is greater than the flow area of ​​the second pipe segment 220, and correspondingly, the flow area of ​​the transition pipe segment 230 gradually decreases in the flow direction of the first pipe segment 210 toward the second pipe segment 220, for example, the transition pipe segment 230 is funnel-shaped, trumpet-shaped, etc.

[0048] The fluid flows in the first pipe segment 210 along the axial direction of the first pipe segment 210, and the fluid flows in the second pipe segment 220 along the axial direction of the second pipe segment 220. The angle between the axial direction of the first pipe segment 210 and the axial direction of the second pipe segment 220 is α, and α satisfies: 60°≤α≤120°. In the embodiment of the present application, α is 90°, which is convenient for processing the first butt joint pipe 200 and making the flow resistance of the fluid in the first butt joint pipe 200 small. At the same time, when laying out the pipeline, the space occupied by the first butt joint pipe 200 can be small, so as to facilitate the layout of the installation positions of other pipelines or other structural parts.

[0049] Optionally, the outer peripheral wall of the first pipe section 210 is sealed and connected to the wall surface of the first flow section 21 defined by the module body 100, so that the fluid in the accommodating chamber 20 can completely enter the first docking tube 200 when flowing into the first docking tube 200, and flow out of the pipeline integrated module 10 after being guided by the first docking tube 200, thereby reducing the flow resistance of the fluid flowing out of the pipeline integrated module 10.

[0050] The accommodating chamber 20 includes a second flow section 22 connected to the first flow section 21, the flow area at the intersection of the second flow section 22 and the first flow section 21 is a1, the flow area of ​​the second flow section 22 is a2, a2>a1, and the accommodating chamber 20 is provided to further include the second flow section 22, so that the accommodating chamber 20 has more space for accommodating fluid. Optionally, the flow area of ​​the first flow section 21 is smaller than the flow area of ​​the second flow section 22, so that it is convenient to match the pipe diameter size requirements of the first butt joint pipe 200, and it is convenient to set the connection structure to improve the installation stability of the first pipe section 210 installed in the first flow section 21. In some other embodiments, the flow area of ​​the second flow section 22 may also be equal to the flow area of ​​the first flow section 21.

[0051] In the axial direction of the first pipe section 210, the first pipe section 210 has a flow guide opening end 210a away from the second pipe section 220, and the flow guide opening end 210a is arranged toward the second flow section 22, and the fluid passing through the flow guide opening end 210a can directly enter and exit the second flow section 22. Optionally, the first flow section 21 is coaxially arranged with the first pipe section 210, and the first flow section 21 and the second flow section 22 both have a central axis and the central axes of the two are parallel, so that when the fluid enters and exits the second flow section 22 through the first pipe section 210, the flow resistance is smaller. Furthermore, the central axes of the first flow section 21 and the second flow section 22 are colinear, so that the fluid flows more smoothly in the accommodating cavity 20 with smaller flow resistance.

[0052] Optionally, when the flow area a1 at the intersection of the second flow segment 22 and the first flow segment 21 is smaller than the flow area a2 of the second flow segment 22, in the flow direction from the second flow segment 22 toward the first flow segment 21, at least part of the flow area of ​​the second flow segment 22 gradually decreases. Furthermore, the flow area of ​​the region where the second flow segment 22 is connected to the first flow segment 21 gradually decreases, thereby preventing the occurrence of water flow instability caused by a sudden change in fluid pressure due to a sudden change in the flow area, thereby effectively reducing the flow resistance.

[0053] In order to improve the installation stability of the first pipe section 210 installed in the first flow section 21, the area where the first pipe section 210 is connected to the module body 100 can be increased. For example, the length of the first pipe section 210 is increased, and the outer peripheral wall of the first pipe section 210 is all connected to the wall surface of the module body 100 that defines the first flow section 21. At least one of these two design methods can increase the connection area and improve the installation stability of the first pipe section 210. It can be understood that when the fluid flows at the transition point of two interfaces, the smoother the transition of the two interfaces, the smoother the flow state of the fluid flowing through the interface transition point, and the smaller the flow resistance. In the embodiment of the present application, the diversion opening end 210a is arranged at the junction of the first flow section 21 and the second flow section 22; or, the diversion opening end 210a is arranged in the first flow section 21, so that the first pipe section 210 does not extend into the second flow section 22, reducing the flow resistance and improving the stability of the fluid flow.

[0054] The module body 100 includes a plurality of protrusions 101, which define a receiving cavity 20. In the thickness direction A of the module body 100, the protrusions 101 protrude toward one side of the module body 100; or, the protrusions 101 protrude toward opposite sides of the module body 100, so as to increase the capacity of the receiving cavity 20.

[0055] like Figure 5As shown, the raised portion 101 includes a first convex hump 1011, a first convex tube 1012 connected to the first convex hump 1011, and a second convex tube 1013 connected to the first convex tube 1012. The first convex hump 1011 defines a reversing space 24, the first convex hump 1011 has a first opening 23 connected to the reversing space 24, the first convex tube 1012 defines a first flow segment 21 connected to the reversing space 24, and the second convex tube 1013 defines a second flow segment 22 connected to the first flow segment 21. When the pipeline integrated module 10 is not provided with the first butt joint tube 200, the fluid will enter the reversing space 24 from the first opening 23, and after reversing at the reversing space 24, it will flow to the first flow segment 21 and the second flow segment 22 in sequence, and the fluid will impact the wall surface of the first convex hump 1011 in the reversing space 24 and suddenly reverse, so it is easy to form a vortex in the reversing space 24, and the flow resistance is large. In the embodiment of the present application, the first pipe section 210 is connected to the wall surface of the first convex tube 1012 defining the first flow section 21, and the second pipe section 220 is connected to the wall surface of the first convex bump 1011 defining the first opening 23, so that the first butt joint pipe 200 can be stably fixed to the module body 100, preventing the part of the first butt joint pipe 200 accommodated in the accommodating cavity 20 from shaking and causing noise when the fluid passes due to unstable connection. Furthermore, the second pipe section 220 is sealedly connected to the wall surface of the first convex bump 1011 defining the first opening 23, preventing substances from entering and exiting the accommodating cavity 20 from the first opening 23.

[0056] Optionally, in the thickness direction A of the module body 100, the first convex bumps 1011 protrude toward opposite sides of the module body 100, and when the first butting tube 200 further includes a transition tube section 230, the switching space 24 of the first convex bump 1011 has sufficient volume to accommodate the transition tube section 230. The outer peripheral wall of the transition tube section 230 may be spaced apart from the inner wall surface of the first convex bump 1011; or, the outer peripheral wall of the transition tube section 230 is connected to the first convex bump 1011, so as to directly fix the transition tube section 230 to the first convex bump 1011. The above two installation methods can prevent the transition pipe segment 230 from vibrating and colliding with the first convex hump 1011 to generate noise when the transition pipe segment 230 is in contact with the first convex hump 1011. For example, the situations that cause the transition pipe segment 230 to vibrate include: the fluid flows to the transition pipe segment 230, causing the transition pipe segment 230 to vibrate; or, sound insulation and noise reduction material is arranged between the inner wall surface of the first convex hump 1011 and the outer wall surface of the transition pipe segment 230, thereby further reducing the noise at the fluid turning point and preventing vibration noise, wherein the sound insulation and noise reduction material can be sponge, foam or other materials.

[0057] Alternatively, if Figure 4As shown, the raised portion 101 also includes a first flange 102 arranged around the periphery of the first opening 23. Specifically, the first flange 102 is connected to the first bulge 1011. In the opening direction of the first opening 23, the first flange 102 extends to the side away from the first bulge 1011. When the second pipe segment 220 is installed at the first opening 23, the first flange 102 is also connected to the outer peripheral wall of the second pipe segment 220, thereby increasing the connection area between the second pipe segment 220 and the module body 100 and improving the installation stability of the second pipe segment 220.

[0058] Alternatively, if Figure 5 As shown, in the extension direction of the first flange 102, the height of the first flange 102 is P, and P satisfies: 1mm≤P≤4mm. For example, P can be 1mm, 2mm, 2.5mm, 3mm or 4mm, etc., so that the connection area between the first flange 102 and the second tube segment 220 is appropriate, improving the connection stability, and also facilitating the formation of a good seal at the first flange 102 to prevent substances from entering and exiting the accommodating cavity 20 from between the first flange 102 and the second tube segment 220.

[0059] Please refer to Figure 2 and Figure 3 The module body 100 includes a first plate body 110 and a second plate body 120 which are connected to each other in a covering manner. At least one of the first plate body 110 and the second plate body 120 has a groove. The grooves of the first plate body 110 and the second plate body 120 form a receiving cavity 20 for circulating a heat exchange medium.

[0060] like Figure 3 and Figure 4 As shown, when the first plate body 110 has a groove, the groove of the first plate body 110 is a first groove 1111. Optionally, the first plate body 110 has a first convex portion 111 protruding in a direction away from the second plate body 120, and the first convex portion 111 defines a first groove 1111. The wall surface of the first groove 1111 and the wall surface of the second plate body 120 corresponding to the first groove 1111 jointly define a accommodating cavity 20 for circulating a heat exchange medium, and the first convex portion 111 and the corresponding portion of the second plate body 120 jointly form a raised portion 101.

[0061] When the second plate body 120 has a groove, the groove of the second plate body 120 is a second groove 1211. Optionally, the second plate body 120 has a second convex portion 121 that protrudes away from the first plate body 110. The second convex portion 121 defines the second groove 1211. The wall surface of the second groove 1211 and the wall surfaces corresponding to the first plate body 110 and the second groove 1211 jointly define a accommodating cavity 20 for the circulation of heat exchange medium, and the second convex portion 121 and the corresponding portion of the first plate body 110 jointly form a raised portion 101.

[0062] When both the first plate body 110 and the second plate body 120 have grooves, the groove of the first plate body 110 is the first groove 1111, and the groove of the second plate body 120 is the second groove 1211. Optionally, the first plate body 110 has a first convex portion 111 protruding in a direction away from the second plate body 120, the first convex portion 111 defines a first groove 1111, the second plate body 120 has a second convex portion 121 protruding in a direction away from the first plate body 110, the second convex portion 121 defines a second groove 1211, the first groove 1111 and the second groove 1211 together form the accommodating chamber 20, and the first convex portion 111 and the second convex portion 121 together form the convex portion 101, so that it is convenient to expand the accommodating chamber 20, increase the flow area of ​​the accommodating chamber 20, and increase the volume of the fluid that the accommodating chamber 20 can accommodate.

[0063] Optionally, the first plate body 110 and the second plate body 120 are respectively made of metal materials such as steel alloy and aluminum alloy. Preferably, the first plate body 110 and the second plate body 120 are made of the same material. The first plate body 110 and the second plate body 120 can be made by a stamping process, that is, the first plate body 110 is stamped to form the first convex portion 111, and the second plate body 120 is stamped to form the second convex portion 121.

[0064] The first plate body 110 further includes a first flat portion 112, which is connected to the first convex portion 111. The second plate body 120 further includes a second flat portion 122, which is connected to the second convex portion 121. When the first plate body 110 and the second plate body 120 are covered, the first flat portion 112 and the second flat portion 122 are sealed to ensure the sealing of the accommodating cavity 20 and the second cavity 30. The first convex portion 111 is convexly arranged on the surface of the first flat portion 112 away from the second plate body 120, and the second convex portion 121 is convexly arranged on the surface of the second flat portion 122 away from the first plate body 110.

The first plate body 110 and the second plate body 120 are sealed and connected via the plywood layer. Specifically, the plywood layer is connected between the first flat portion 112 and the second flat portion 122 .

[0066] The sandwich layer includes at least one of a first sandwich layer 410 and a second sandwich layer (not shown in the figure), the first sandwich layer 410 is connected between the first plate body 110 and the second plate body 120, and the second sandwich layer is connected between the first plate body 110 and the second plate body 120. Figure 6As shown, the first interlayer 410 includes a support plate 411, a first adhesive layer 412 connected between the support plate 411 and the first plate body 110, and a second adhesive layer 413 connected between the support plate 411 and the second plate body 120. The first adhesive layer 412, the second adhesive layer 413 and the second interlayer all include adhesive materials and can be connected to the first plate body 110 and the second plate body 120. Among them, the first interlayer 410 is used to bond the first plate body 110 and the second plate body 120. Compared with the second interlayer, the first plate body 110 and the second plate body 120, the bonding part bonded by the first plate body 110 has better impact resistance stability, and is more suitable for bonding near a cavity with a larger load. The embodiment of the present application does not limit which part of the area between the first plate body 110 and the second interlayer is bonded to, and can be selected according to actual needs.

[0067] Optionally, when the pipeline integrated module 10 includes a plurality of accommodating cavities 20, the first interlayer 410 is disposed around a portion of the accommodating cavities 20, and is connected to the first plate body 110 and the second plate body 120 to form a sealing structure between the first plate body 110 and the second plate body 120; the second interlayer is disposed around another portion of the accommodating cavities 20, and is connected to the first plate body 110 and the second plate body 120 to form a sealing structure between the first plate body 110 and the second plate body 120. For example, when the capacity of one accommodating cavity 20 is greater than the capacity of another accommodating cavity 20, the first interlayer 410 may be disposed around the accommodating cavity 20 with a larger capacity, and the second interlayer may be disposed around the accommodating cavity 20 with a smaller capacity.

Under the frequent impact of the fluid in the accommodating cavity 20 and the second cavity 30, there is still a good sealing effect between the first plate body 110 and the second plate body 120.

[0069] Among them, when the embodiment of the present application adopts stamping to process the first plate body 110 and the second plate body 120, the notch of the first groove 1111 of the first plate body 110 has a first stamping chamfer, and the notch of the second groove 1211 of the second plate body 120 has a second stamping chamfer. The end of the support plate 411 of the first interlayer 410 extends between the first stamping chamfer and the second stamping chamfer, and the first adhesive layer 412 also extends to fill between the first chamfer 111a and the support plate 411, and the second adhesive also extends to fill between the second chamfer 121a and the support plate 411. In this way, the ability of the first plate body 110 and the second plate body 120 to withstand the impact of the fluid in the accommodating cavity 20 can be effectively improved, thereby effectively improving the stability of the pipeline integrated module 10.

[0070] The first plate 110 of the above embodiment may have one or more first protrusions 111, and the second plate 120 may have one or more second protrusions 121.

Among them, the outer surface of the first pipe section 210 is respectively fitted with the wall surfaces of the first plate 110 and the second plate 120, so that when the second plate 120 is covered on the first plate 110, the first pipe section 210 can pre-position the position of the second plate 120 relative to the first plate 110, and prevent the second plate 120 from moving relative to the first plate 110 in a plane perpendicular to the thickness direction A of the module body 100, so as to facilitate assembly.

[0072] Optionally, the first butt joint pipe 200 is fixed to the module body 100 by welding, for example, the first pipe section 210 is welded to the wall surface of the module body 100 defining the first flow section 21, and the second pipe section 220 is welded to the wall surface of the module body 100 defining the first opening 23, so as to facilitate assembly and improve the installation stability of the first butt joint pipe 200 installed on the module body 100. Specifically, the gap between the first pipe section 210 and the first plate body 110 and the gap between the second pipe section 220 and the second plate body 120 are filled with solder, and then connected by welding; the gap between the second pipe section 220 and the first plate body 110 is filled with solder, and then connected by welding.

Figure 7 As shown, the second butt joint tube 300 can extend into the accommodating cavity 20, and the length of the second butt joint tube 300 extending into the accommodating cavity 20 is L, and L satisfies: 0≤L≤5mm, and the end of the second butt joint tube 300 extending into the accommodating cavity 20 is spaced apart from the wall of the module body 100 that defines the accommodating cavity 20, to prevent the end of the second butt joint tube 300 from being blocked to increase the flow resistance.

[0074] Furthermore, the protrusion 101 further includes a second flange 103 disposed around the second opening 31, the second flange 103 extends in the direction away from the accommodating cavity 20 in the opening direction of the second opening 31, and the second flange 103 is connected to the outer peripheral wall of the second butt joint tube 300. Specifically, the gap between the second flange 103 and the outer peripheral wall of the second butt joint tube 300 is filled with solder, and then connected and fixed by welding. Figure 7 As shown, in the extension direction of the second flange 103, the height of the second flange 103 is B, and B satisfies: 1mm≤B≤4mm. For example, B can be 1mm, 2mm, 2.5mm, 3mm or 4mm, etc., so that the connection area between the second flange 103 and the second butt joint 300 is appropriate, the connection stability is improved, and a good seal is formed.

[0075] Optionally, the openings communicating with the same accommodating cavity 20 include at least one first opening 23 and at least one second opening 31, the first opening 23 is provided with a first butt joint pipe 200, and the second opening 31 is not provided with a first butt joint pipe 200. For example, please refer to Figure 1 and Figure 2 , the openings communicating with the same accommodating chamber 20 include a first opening 23 and a second opening 31, and the fluid enters the accommodating chamber 20 from the first opening 23 and flows out of the accommodating chamber 20 from the second opening 31; or, the openings communicating with the same accommodating chamber 20 are all first openings 23 and there are multiple openings, for example, there are two first openings 23 communicating with the same accommodating chamber 20, and the fluid enters the accommodating chamber 20 from one of the first openings 23 and flows out of the accommodating chamber 20 from the other second opening 31.

[0076] When the openings communicating with the same accommodating cavity 20 include a first opening 23 and a second opening 31, the opening direction of the first opening 23 is the same as the opening direction of the second opening 31. For example, the first opening 23 and the second opening 31 are both opened on the outer surface of the first plate 110, and the first butt joint pipe 200 and the second butt joint pipe 300 are assembled on the same side of the module body 100.

At this time, the fluid will enter the second flow segment 22 after passing through the first flow segment 21 at the first opening 23, and be squeezed out of the second flow segment 22 at the second opening 31, so that the flow of the fluid in the second flow segment 22 is more stable, and when the fluid flows out of the second flow segment 22, the flow resistance is prevented from increasing due to the increase in flow pressure caused by the flow area changing from large to small. Among them, the second opening 31 can be opened corresponding to the middle part of the second flow segment 22; or, the second opening 31 can be opened adjacent to the end of the second flow segment 22 away from the first flow segment 21.

[0085] The module body 100 has two first openings 23 communicating with the third chamber 203. The first butt joint pipe 200 at one of the first openings 23 of the third chamber 203 is in communication with the second butt joint pipe 300 at the second opening 31 of the second chamber 202. Furthermore, a first electronic expansion valve 510 is in communication between the second butt joint pipe 300 and the first butt joint pipe 200 there, and the flow rate of the fluid flowing between the second chamber 202 and the third chamber 203 is adjusted by the first electronic expansion valve 510.

The outdoor heat exchanger 610 then transports the refrigerant to the second filter chamber 202.
