DETAILED DESCRIPTION

[0051] 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.

[0052] The pipeline integration module of the air conditioner outdoor unit includes two plates, and grooves are processed on the two plates. After docking, the grooves form a sealed cavity. When there is fluid in the cavity of the pipeline integration module, the larger the capacity of the cavity, the more volume of fluid it contains, the greater the load, and when the static load or alternating load that the part of the cavity defined by the pipeline integration module can withstand is lower, the pipeline integration module is more likely to deform. For example, the two plates are connected and fixed by welding. The greater the load on the cavity, the worse the pressure resistance stability of the connection between the two plates that define the cavity, and the lower the static load or alternating load that can be borne, which can easily cause the connection between the two plates to tear, causing deformation of the pipeline integration module.

[0053] like Figure 1 and Figure 2 FIG. 1 is a schematic diagram of the structure 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 plywood layer 200. The module body 100 includes two plates, which are covered and arranged, and the plywood layer 200 is used to connect between the two plates to connect and fix the two plates.

[0054] Specifically, one of the two plates is the first plate 110, and the other plate is the second plate 120. The sandwich layer 200 includes a first interlayer 210 and a second interlayer 220. The first interlayer 210 is connected between the first plate 110 and the second plate 120, and the first interlayer 210, the first plate 110 and the second plate 120 together define a first cavity 101; the second interlayer 220 is connected between the first plate 110 and the second plate 120, and the second interlayer 220, the first plate 110 and the second plate 120 together define a second cavity 102. The first cavity 101 and the second cavity 102 are both used to accommodate fluid, and the flow area of ​​the first cavity 101 is greater than the flow area of ​​the second cavity 102. Further, the amount of fluid that can be loaded inside the first cavity 101 is greater than the amount of fluid that can be loaded inside the second cavity 102.

[0055] It can be understood that there is a gap between the parts of the first plate 110 and the second plate 120 that participate in defining the first cavity 101. Similarly, there is a gap between the parts of the first plate 110 and the second plate 120 that participate in defining the second cavity 102. Since the flow area of ​​the first cavity 101 is larger than the flow area of ​​the second cavity 102, the gap area of ​​the parts of the first plate 110 and the second plate 120 that participate in defining the first cavity 101 is larger than the gap area of ​​the parts of the first plate 110 and the second plate 120 that participate in defining the first cavity 101. The plates with larger gap areas are more likely to deform. Moreover, when the first plate 110 and the second plate 120 in the peripheral area of ​​the first cavity 101 are connected, the fluid pressure that the area needs to withstand is greater. Correspondingly, the fluid pressure borne at the connection between the first interlayer 210, the first plate 110 and the second plate 120 that defines the first cavity 101 is m1, and the fluid pressure borne at the connection between the second interlayer 220, the first plate 110 and the second plate 120 that defines the second cavity 102 is m2, and m1>m2. Based on this, when fixing the plates in the peripheral areas of cavities with different flow areas, the embodiments of the present application take different countermeasures.

[0056] The first interlayer 210 includes a support plate 211, a first adhesive layer 212 connected between the support plate 211 and the first plate body 110, and a second adhesive layer 213 connected between the support plate 211 and the second plate body 120. The support plate 211 has structural strength, and is used to provide support for the first plate body 110, the second plate body 120, the first adhesive layer 212, and the second plate body 120, to prevent the first plate body 110 and the second plate body 120 from being deformed when they are respectively connected to the first interlayer 210, and to improve the connection stability between the first adhesive layer 212 and the first plate body 110 and the support plate 211, and to improve the connection stability between the second adhesive layer 213 and the second plate body 120 and the support plate 211. Even when the flow area of ​​the first cavity 101 is large, the connection between the first plate body 110, the second plate body 120 and the first interlayer 210 still has good connection stability.

[0057] In the embodiment of the present application, for the cavities with different flow areas of the module body 100, different types of interlayers are arranged in the corresponding peripheral areas of the cavities to connect the first plate body 110 and the second plate body 120, and the first plate body 110 and the second plate body 120 are connected by the first interlayer 210 having a support plate 211 in the peripheral area of ​​the first cavity 101 with a larger flow area, and the first plate body 110 and the second plate body 120 are directly connected by the second interlayer 220 in the peripheral area of ​​the second cavity 102 with a smaller flow area, so as to prevent the situation that the connection between the first plate body 110 and the second plate body 120 in different peripheral areas of the cavity is difficult to cope with different pressures and the connection stability is reduced. In particular, when a connecting structure is provided between the first plate body 110 and the second plate body 120 to connect and fix the two plate bodies, the first plate body 110 and the second plate body 120 are connected by a sandwich structure such as a first interlayer 210 having a support plate 211 inside, which can effectively improve the tear strength of the first plate body 110 and the second plate body 120 near a cavity with a larger flow area.

[0058] The first plate body 110 and the second plate body 120 are both formed by a stamping process. Figure 2As shown, the first plate 110 is punched to form a first groove 1011, and the second plate 120 is punched to form a second groove 1012. When the first plate 110 and the second plate 120 are overlapped, the second groove 1012 is arranged corresponding to the first groove 1011 and encloses and defines the first cavity 101. Among them, the first plate 110 and the second plate 120 processed by the stamping process are prone to poor plate flatness. If the first plate 110 and the second plate 120 have wrinkles, bulges, poor flatness and other defects at the same position, when the first plate 110 and the second plate 120 are overlapped, gaps will overlap, which is not conducive to the connection stability at the gap and easily leads to low strength of the connection structure at that location. Figure 3 and Figure 4 The notch of the first groove 1011 of the stamped first plate 110 has a first stamped chamfer 101a, and the notch of the second groove 1012 of the stamped second plate 120 has a second stamped chamfer 101b. When the stamped first plate 110 and the second plate 120 are overlapped, a gap is formed between the first stamped chamfer 101a and the second stamped chamfer 101b, causing the formed first cavity 101 to be deformed. When the first cavity 101 is subjected to a large static load or alternating load, the gap between the first stamped chamfer 101a and the second stamped chamfer 101b is prone to tearing, resulting in poor performance of the first cavity 101 in withstanding static loads and alternating loads.

[0059] Optionally, the first interlayer 210 is arranged to extend between the first stamping chamfer 101a and the second stamping chamfer 101b, so that the first interlayer 210 can have as much area as possible to connect with the first plate body 110 and the second plate body 120, thereby improving the connection stability and tear resistance at the first stamping chamfer 101a and the second stamping chamfer 101b, and also preventing the fluid from entering between the first stamping chamfer 101a and the second stamping chamfer 101b to directly flush the connection between the first stamping chamfer 101a and the second stamping chamfer 101b. Among them, the support plate 211 extends between the first stamping chamfer 101a and the second stamping chamfer 101b, which can further improve the support stability of the support plate 211 on the first plate body 110 and the second plate body 120, and reduce the deformation of the first cavity 101.

[0060] Optionally, the first adhesive layer 212 extends to the surface connected to the support plate 211 facing the first stamping chamfer 101a, and the first adhesive layer 212 is connected to the first stamping chamfer 101a, and the first adhesive layer 212 is filled in the gap between the support plate 211 and the first stamping chamfer 101a to prevent the fluid from entering the gap between the support plate 211 and the first stamping chamfer 101a, thereby improving the tear strength of the connection between the support plate 211 and the first stamping chamfer 101a.

[0061] Optionally, the second adhesive layer 213 extends to the surface connected to the support plate 211 facing the second stamped chamfer 101b, and the second adhesive layer 213 is connected to the second stamped chamfer 101b, and the second adhesive layer 213 is filled in the gap between the support plate 211 and the second stamped chamfer 101b to prevent the fluid from entering the gap between the support plate 211 and the second stamped chamfer 101b, thereby improving the tear strength at the connection between the support plate 211 and the second stamped chamfer 101b.

[0062] Furthermore, the first interlayer 210 extends to fill the gap between the first stamping chamfer 101a and the second stamping chamfer 101b, that is, the first adhesive layer 212 fills the gap between the support plate 211 and the first stamping chamfer 101a, and the second adhesive layer 213 fills the gap between the support plate 211 and the second stamping chamfer 101b, thereby increasing the filling degree of the first interlayer 210 between the first stamping chamfer 101a and the second stamping chamfer 101b, and further increasing the connection stability and tear strength between the first stamping chamfer 101a and the second stamping chamfer 101b.

[0063] In the embodiment of the present application, when the first plate 110 and the second plate 120 are covered, welding is used to achieve the connection between the first plate 110 and the second plate 120 near the first cavity 101, wherein the first adhesive layer 212 is a foil-like solder or a paste-like solder, and the second adhesive layer 213 is a foil-like solder or a paste-like solder. A first interlayer 210 is arranged to extend to the gap between the first stamping chamfer 101a and the second stamping chamfer 101b, and a first adhesive layer 212 is used to fill the gap between the support plate 211 and the first stamping chamfer 101a; and / or, a second adhesive layer 213 is used to fill the gap between the support plate 211 and the second stamping chamfer 101b, so that the filling degree between the first stamping chamfer 101a and the second stamping chamfer 101b is higher, which can effectively reduce the pressure on the first stamping chamfer 101a and the second stamping chamfer 101b when the load on the first cavity 101 is large, and improve the pressure resistance and fatigue resistance of the first cavity 101 formed by splicing the first plate body 110 and the second plate body 120 formed by stamping. Moreover, under the support of the support plate 211, it is more conducive to the spreading and forming of the fiber materials of the first adhesive layer 212 and the second adhesive layer 213, and reduces the deformation of the first plate body 110 and the second plate body 120 caused by the stress during stamping of the first plate body 110 and the second plate body 120 during welding, thereby improving the connection stability.

[0064] Optionally, the support plate 211 is a hard metal support plate 211. The support plate 211 made of metal material has good structural strength and thermal conductivity. For example, the support plate 211 is a hard stainless steel support plate 211, a copper support plate 211 or an iron support plate 211.

[0065] In addition, the support plate 211 extends between the first stamping chamfer 101a and the second stamping chamfer 101b, dividing the gap between the first stamping chamfer 101a and the second stamping chamfer 101b into two small gaps. It can be understood that under the traction of capillary force, the material of the first adhesive layer 212 can directly extend to fill the gap between the first stamping chamfer 101a and the support plate 211, and the material of the second adhesive layer 213 can directly extend to fill the gap between the second stamping chamfer 101b and the support plate 211, which helps to improve the filling degree between the first stamping chamfer 101a and the second stamping chamfer 101b.

[0066] Optionally, when the first plate 110 and the second plate 120 are covered, welding can be used to connect the first plate 110 and the second plate 120 near the second cavity 102, and the second interlayer 220 is foil solder or paste solder.

[0067] The foil solder or paste solder described in the embodiment of the present application is a material in two different states. Optionally, the foil solder is fixed between the two layers of the plate body by resistance spot welding, thereby realizing the welding and fixing of the two layers of the plate body; the paste solder is coated on the wall surface of the plate body, and the plate bodies on both sides are connected after the paste solder is solidified, thereby realizing the welding and fixing of the two layers of the plate body. The materials of the foil solder or paste solder include copper fiber, tin, etc.

[0068] Optionally, the first plate 110 is punched to form a third groove 1021, and the second plate 120 is punched to form a fourth groove 1022. When the first plate 110 and the second plate 120 are overlapped, the third groove 1021 and the fourth groove 1022 together define the second cavity 102. Figure 4 As shown, the notch of the third groove 1021 forms a third chamfer 201a, the notch of the fourth groove 1022 forms a fourth chamfer 201b, and the second interlayer 220 also fills the gap between the third chamfer 201a and the fourth chamfer 201b, that is, the second interlayer 220 also connects the third chamfer 201a and the fourth chamfer 201b, thereby improving the connection stability and tear resistance between the third chamfer 201a and the fourth chamfer 201b, and improving the static load or alternating load that the second cavity 102 can withstand.

[0069] The embodiment of the present application has a plurality of first cavities 101 and a plurality of second cavities 102. The number of first interlayers 210 may be a plurality corresponding to the plurality of first cavities 101, and the number of second interlayers 220 may be a plurality corresponding to the plurality of second cavities 102. The first interlayer 210 and the second interlayer 220 are arranged at intervals, wherein the adjacent plurality of first interlayers 210 are arranged at intervals or are arranged as a whole, and the adjacent plurality of second interlayers 220 are arranged at intervals or are arranged as a whole, for example, Figure 2 As shown, the number of first cavities 101 is two, the number of second cavities 102 is multiple, and at least one of the second cavities 102 is located between two first cavities 101, then the two first interlayers 210 corresponding to the two first cavities 101 are arranged at intervals, and the multiple second interlayers 220 corresponding to the multiple second cavities 102 are arranged integrally.

[0070] It is understandable that, due to the existence of the support plate 211, and the first adhesive layer 212 and the second adhesive layer 213 are respectively provided on the opposite sides of the support plate 211, the thickness of the first interlayer 210 is thicker than the thickness of the second interlayer 220. Optionally, multiple first interlayers 210 are arranged at intervals, so that the first interlayer 210 is correspondingly arranged at the periphery of the first cavity 101, and then the position of the first cavity 101 is flexibly designed. Among them, when multiple second interlayers 220 are correspondingly arranged at the periphery of the second cavity 102, and multiple second interlayers 220 are arranged in one piece, the second interlayer 220 can cover more areas, further improve the connection strength of the first plate body 110 and the second plate body 120, and help to improve the flatness of the processed pipeline integrated module 10.

[0071] Since the thickness of the first interlayer 210 is relatively thick, the embodiment of the present application further provides at least one of the first plate body 110 and the second plate body 120 with a limiting groove 1013, and the limiting groove 1013 is used to accommodate the first interlayer 210, so as to prevent the first interlayer 210 from occupying a large space in the thickness direction A of the pipeline integrated module 10, resulting in a large distance between the first plate body 110 and the second plate body 120, and thus causing the two plates to tear, and also helps to reduce the amount of material used in the second interlayer 220. Optionally, the first plate body 110 has a limiting groove 1013 arranged around the periphery of the first groove 1011; and / or, the second plate body 120 has a limiting groove 1013 arranged around the periphery of the second groove 1012.

[0072] When the first plate body 110 has a limiting groove 1013 arranged around the outer periphery of the first groove 1011, specifically, the limiting groove 1013 is opened on the surface of the first plate body 110 facing the second plate body 120, and further, the bottom wall of the limiting groove 1013 is opened with the first groove 1011.

[0073] When the second plate body 120 has a limiting groove 1013 arranged around the outer periphery of the second groove 1012 , specifically, the limiting groove 1013 is opened on the surface of the second plate body 120 facing the second plate body 120 , and further, the bottom wall of the limiting groove 1013 is opened with the second groove 1012 .

[0074] Among them, the limiting groove 1013 is a contoured groove corresponding to the first interlayer 210. The first interlayer 210 is arranged in the limiting groove 1013, and the wall surface of the limiting groove 1013 is limited to contact with the surface of the first interlayer 210, so as to facilitate the positioning of the first interlayer 210 and limit the position of the first interlayer 210 perpendicular to the thickness direction A of the pipeline integrated module 10.

[0075] Optionally, a plurality of docking openings 111 are provided on one surface of the first plate 110 and the second plate 120, the first cavity 101 is connected to at least one docking opening 111, the second cavity 102 is connected to at least one docking opening 111, and a docking pipe 300 is plugged into each docking opening 111. In the embodiment of the present application, the docking pipes 300 are centrally installed on the first plate 110 or the second plate 120, so as to improve the integration of the plurality of docking pipes 300. For example, the surface of the first plate 110 facing away from the second plate 120 is provided with the docking opening 111, and the surface of the second plate 120 facing the first plate 110 is provided with a limiting groove 1013 arranged around the outer periphery of the second groove 1012.

[0076] Among them, in order to improve the flatness of the pipeline integrated module 10 processed between the first interlayer 210 and the second interlayer 220 connected to the first plate body 110 and the second plate body 120, in the covering direction of the first plate body 110 and the second plate body 120 (that is, the thickness direction A of the pipeline integrated module 10), the depth of the limiting groove 1013 is H, the thickness of the first interlayer 210 is h1, and the thickness of the second interlayer 220 is h2, wherein H+h2=h1, to prevent the thickness of the first interlayer 210, the thickness of the second interlayer 220 and the depth of the limiting groove 1013 from not matching, and gaps appearing at the connections, resulting in unstable connection between the first plate body 110 and the second plate body 120.

[0077] Optionally, H satisfies: 0.2 mm ≤ H ≤ 0.5 mm, so as to facilitate machining the limiting groove 1013 on the surface of the first plate body 110 or the second plate body 120 and meet the limiting requirement of the limiting groove 1013 on the first interlayer 210 .

[0078] Optionally, in the covering direction of the first plate body 110 and the second plate body 120, the thickness of the first adhesive layer 212 is n1, and n1 satisfies: 0.05mm≤n1≤1mm; the thickness of the first adhesive layer 212 is n2, and n2 satisfies: 0.05mm≤n2≤1mm; the thickness of the second interlayer 220 is h2, and h2 satisfies: 0.05mm≤h2≤1mm. Further, n1≤h2, and n2≤h2, n1 and n2 may be equal or unequal. Among them, n1 is the thickness of the first adhesive layer 212 that does not extend between the first stamping chamfer 101a and the support plate 211, n2 is the thickness of the second adhesive layer 213 that does not extend between the second stamping chamfer 101b and the support plate 211, h1 is the thickness of the first interlayer 210 that does not extend between the first stamping chamfer 101a and the second stamping chamfer 101b, and h2 is the thickness of the second interlayer 220 that does not extend between the third chamfer and the fourth chamfer.

[0079] In the embodiment of the present application, the thickness of the first adhesive layer 212 filled to the portion between the first stamping chamfer 101a and the support plate 211, the thickness of the second adhesive layer 213 filled to the portion between the second stamping chamfer 101b and the support plate 211, and the thickness of the second interlayer 220 filled to the portion between the third chamfer and the fourth chamfer can be determined according to the stamping angle of each stamping chamfer, and the higher the filling degree at each location, the better the compressive strength of each connection, and the lower the risk of being torn. For example, if the stamping angles at the first stamping chamfer 101a, the second stamping chamfer 101b, the third chamfer and the fourth chamfer are 90°, and the radius of the stamping chamfer is 5mm, then the thickness x of the first adhesive layer 212 filled to the portion between the first stamping chamfer 101a and the support plate 211 is 100 mm. 1 The second adhesive layer 213 is filled to a thickness x between the second stamping chamfer 101b and the support plate 211. 2 The thickness of the second interlayer 220 filled between the third chamfer and the fourth chamfer can be x 3 is 0.999mm, and h2 can be 0.072mm.

[0080] In the embodiment of the present application, the first interlayer 210 is arranged to extend to fill the gap between the first stamped chamfer 101a and the second stamped chamfer 101b, and the second interlayer 220 is also arranged to fill the gap between the third chamfer and the fourth chamfer. Even if there is frequent reversal of the fluid entering and exiting the first cavity 101 and the second cavity 102, the pipeline integrated module 10 still has good pressure resistance stability.

[0081] like Figure 5As shown, the first cavity 101 and the second cavity 102 are respectively connected to the docking pipelines 300 of different outdoor units. For example, the fluid entering the first cavity 101 from one of the docking pipelines 300 is reversed in the first cavity 101 and then flows out of the first cavity 101 from another docking pipeline 300 and is conveyed to other structures; the fluid entering the second cavity 102 from one of the docking pipelines 300 is reversed in the second cavity 102 and then flows out of the second cavity 102 from another docking pipeline 300 and is conveyed to other structures. The first cavity 101 and its corresponding docking pipeline 300, and the second cavity 102 and its corresponding docking pipeline 300 form two independent passages. The above is only an exemplary introduction, and the specific docking pipelines 300 communicating with the first cavity 101 and the second cavity 102 can be selected according to actual needs, and the present application does not limit this.

[0082] Due to the impact of fluid commutation on the plate wall surface, it is easy to cause the plate to vibrate and generate noise. Optionally, the pipeline integration module is further provided with a sound insulation member 400, and the sound insulation member 400 is connected to the outer surface of the module body 100. Specifically, as Figure 6 and Figure 7 shown, the sound insulation member 400 includes a first sound insulation portion 410 and a second sound insulation portion 420. The first sound insulation portion 410 is disposed on the surface of the first plate body 110 facing away from the second plate body 120, and the second sound insulation portion 420 is disposed on the surface of the second plate body 120 facing away from the first plate body 110. In the thickness direction A of the module body 100, the first sound insulation portion 410 at least partially overlaps with the first cavity 101 and the second cavity 102, and the second sound insulation portion 420 at least partially overlaps with the first cavity 101 and the second cavity 102. By providing the first sound insulation portion 410 and the second sound insulation portion 420, the noise radiation caused by fluid commutation in the first cavity 101 and the second cavity 102 can be effectively reduced. The pipeline integration module 10 is generally installed in the internal space of the housing of the outdoor unit. When the pipeline integration module 10 is installed in the outdoor unit, when the outdoor unit operates, by using the low-noise pipeline integration module 10, the noise of the entire outdoor unit can also be reduced, and the interference of the noise of the outdoor unit on people's lives can be reduced.

[0083] Optionally, the first sound insulation portion 410 and the second sound insulation portion 420 are separately provided. The first sound insulation portion 410 is a sound insulation coating or a sound insulation block, and the second sound insulation portion 420 is a sound insulation coating or a sound insulation block.

[0084] Exemplarily, as Figure 8As shown, the first cavity 101 at least includes an oil separation cavity 500, and one of the second grooves 1012 of the second plate 120 is arranged corresponding to one of the first grooves 1011 of the first plate 110, and the two define the oil separation cavity 500. The oil separation cavity 500 includes an inlet 510 and an outlet 520. One part of the first cavity 101 is connected to the opening 111 to form the inlet 510, and the other part of the opening 111 is connected to form the outlet 520. Specifically, the oil separation cavity 500 includes an intermediate cavity 501 and two transition cavities 502, and the two transition cavities 502 are respectively located at both ends of the intermediate cavity 501, and the intermediate cavity 501 is provided with an inlet 510, and the two transition cavities 502 are respectively provided with outlets 520.

[0085] The plate surface perpendicular to the first plate body 110 and the second plate body 120 is defined as a cross section, and the section parallel to the plate surface of the first plate body 110 and the second plate body 120 is defined as a vertical section. The cross section of the middle cavity 501 is constructed to be circular or elliptical so that the fluid can flow smoothly in the middle cavity 501 and reduce the flow resistance; the cross section and the vertical section of the adapter cavity 502 are both constructed to be non-circular, and the module body 100 defines a portion of the adapter cavity 502 for connection with the docking pipe 300. By setting the shape of the adapter cavity 502, the installation of the docking pipe 300 is facilitated.

[0086] The cross section of the adapter cavity 502 is a polygon, and / or the vertical section of the adapter cavity 502 is a polygon, for example, the cross section of the adapter cavity 502 is constructed as a rectangle, square, hexagon, etc., and the vertical section of the adapter cavity 502 is constructed as a rectangle, square, etc.

[0087] like Figure 8 As shown, the orientation of the inlet 510 of the oil separation chamber 500 and the orientation of each outlet 520 are parallel to the cross section, and the orientation of the inlet 510 and the orientation of each outlet 520 are parallel to each other.

[0088] Please combine again Figure 2 and Figure 3 The first interlayer 210 is respectively arranged on the left and right sides of the middle cavity 501, and the first interlayer 210 is arranged around the transition cavity 502. The first interlayer 210 on the left and right sides of the middle cavity 501 is respectively connected to the first interlayer 210 arranged around the transition cavity 502 at both ends, so that the first interlayer 210 is arranged around the periphery of the oil separation cavity 500, which can effectively improve the pressure resistance stability of the first plate body 110 and the second plate body 120 near the oil separation cavity 500 with a larger flow area.

[0089] The oil-gas mixture enters the middle chamber 501 of the oil separation chamber 500 through the inlet 510, and the refrigerant gas and the oil body are separated in the middle chamber 501. The outlets 520 of the second transfer chamber 502 are respectively the gas outlet 521 and the oil outlet 522. The refrigerant gas separated through the middle chamber 501 of the oil separation chamber 500 is output through the gas outlet 521, and the oil body separated through the middle chamber 501 is output through the oil outlet 522. In this way, the refrigerant gas and the oil body are output through two opposite areas, which facilitates the smooth output of the refrigerant gas and the oil body from the oil separation chamber 500, thereby improving the separation efficiency.

[0090] Please refer to Figure 2 The pipeline integrated module 10 further includes an outlet pipe 530. The two ends of the middle cavity 501 form tapered cavities, each tapered cavity is configured to gradually decrease in size along the direction toward the corresponding transition cavity 502, and the end of each tapered cavity is connected to the corresponding transition cavity 502, so as to guide the fluid in the oil separation cavity 500 to enter and exit the middle cavity 501 and the transition cavity 502 more smoothly. Among them, the end of the tapered cavity connected to the gas outlet 521 forms a neck 503, and the first end of the outlet pipe 530 is fixed to the inner wall of the neck 503. The refrigerant gas enters the outlet pipe 530 and is output from the gas outlet 521 under the guidance of the outlet pipe 530, and the second end of the outlet pipe 530 extends into the middle cavity 501 and extends beyond the inlet 510, so as to prevent the separated refrigerant gas from escaping to the inlet 510 and increasing the resistance of the oil-gas mixture from the inlet 510 to enter the middle cavity 501.

[0091] In the direction perpendicular to the longitudinal section (i.e., the thickness direction A of the module body), the inlet 510 and the outlet pipe 530 are staggered so that the fluid flows around the outlet pipe 530 after entering the middle cavity 501 from the inlet 510, and the fluid collides with the wall surface of the module body 100 and the wall surface of the outlet pipe 530, thereby separating the fluid into gas and oil. Furthermore, the distance from the inlet 510 to the neck 503 is smaller than the distance from the inlet 510 to the oil outlet 522, so as to increase the flow of the oil-gas mixture in the middle cavity 501 under the guidance of the outlet pipe 530, and improve the oil-gas separation rate.

[0092] The first interlayer 210 is respectively provided on both sides of the neck 503 , and the air outlet pipe 530 abuts against the support plate 211 on the corresponding side, which helps to improve the installation stability of the air outlet pipe 530 and improve the impact resistance stability of the connection between the neck 503 and the air outlet pipe 530 .

[0093] A third adhesive layer is provided between the inner wall of the neck 503 and the first end of the air outlet pipe 530, and the third adhesive layer is provided around the first end of the air outlet pipe 530 to form a fully enclosed structure around the first end of the air outlet pipe 530, so as to prevent the fluid from passing through the neck 503 and flowing between the middle front and the air outlet 521. Optionally, the third adhesive layer is a solder, and the first end of the air outlet pipe 530 can be fixed to the neck 503 of the module body 100 through the third adhesive layer by welding.

[0094] The pipeline integrated module 10 also includes a first filter 501, which is arranged in a transfer chamber 502 connected to the oil outlet 522, and the first filter 501 cover is arranged on the oil outlet 522, and the first filter 501 is used to filter the oil separated in the middle chamber 501 and output it from the oil outlet 522.

[0095] Alternatively, if Figure 8 As shown, the first cavity 101 at least includes a filter cavity 600 , and another second groove 1012 of the second plate 120 is arranged corresponding to another first groove 1011 of the first plate 110 , and the two define the filter cavity 600 .

[0096] One of the first groove 1011 and the second groove 1012 is provided with at least two docking openings 111, and the at least two docking openings 111 form a refrigerant inlet and outlet, and the fluid enters and exits the filter cavity 600 from the refrigerant inlet and outlet. The first groove 1011 and the second groove 1012 are provided with a limiting groove 1013 on the circumferential side, and the first interlayer 210 is received in the limiting groove 1013. By providing the first interlayer 210, when the filter cavity 600 has a large static load or a large alternating load, the first plate body 110 and the second plate body 120 can still have good pressure resistance stability.

[0097] The pipeline integrated module 10 further includes a second filter screen 601 disposed in the filter chamber 600 . The second filter screen 601 is covered in one of the docking openings 111 . The second filter screen 601 is used to filter the fluid entering and exiting the filter chamber 600 .

Specifically, the fluid transported by the indoor heat exchanger enters the filter chamber 600 through the air pipe 680, and after being filtered in the filter chamber 600, enters the gas-liquid separator 660 through the second flow path 632. The gas-liquid separator 660 is used to separate the refrigerant mixture from the filtered fluid and transport the refrigerant mixture to the compressor 620. The compressor 620 compresses the refrigerant mixture and transports it to the oil separation chamber 500. The oil separation chamber 500 separates the refrigerant mixture into gas and oil.
