[0057] In order to make the purpose, technical solutions and advantages of the present application clearer, the following further details the present application 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.

[0058] Each adapter pipe of the pipeline integration module needs to be accurately aligned and installed, and only when the connection is stable can the smooth flow of fluid at the pipeline integration module be ensured. The inventor found that setting a smaller gap between the two structural parts at the docking part of the adapter pipe helps to ensure stable welding, and the smaller the gap, the higher the welding quality. However, due to the small gap, it is difficult to assemble and position the two structural parts at the docking part of the adapter pipe, and the assembly accuracy requirements are high. Moreover, the number of docking pipes integrated in the pipeline integration module is large, resulting in low assembly efficiency of the entire pipeline integration module. Based on this, the embodiments of the present application provide a pipeline integration module, an outdoor unit and a heating, ventilation and air conditioning equipment.

[0059] As Figure 1 shown, it is a schematic structural diagram of a pipeline integration module 10 according to an embodiment of the present application. The pipeline integration module 10 includes a module body 100, an adapter pipe 200 and a solder layer 300.

[0060] As Figure 2 and Figure 3 shown, the module body 100 has an adapter opening 101, and the module body 100 further has a receiving cavity 102 inside. The adapter opening 101 communicates with the receiving cavity 102. The adapter pipe 200 is correspondingly arranged at the adapter opening 101 and installed on the module body 100, and the channel inside the adapter pipe 200 communicates with the receiving cavity 102, so that fluid can flow in the space between the receiving cavity 102 and the inside of the adapter pipe 200.

[0061] The adapter tube 200 includes a tube body 210 and a connection section 220 connected to the tube body 210. The connection section 220 is inserted into the connection opening 101. Among them, the outer surface of the connection section 220 includes a guiding inclined surface 221. Along the direction away from the tube body 210, the distance from the guiding inclined surface 221 to the central axis H of the connection section 220 gradually decreases and extends to the edge of the connection section 220. In this way, in the direction perpendicular to the axial direction of the connection section 220, the guiding inclined surface 221 is spaced from the wall surface of the connection opening 101, and the distance from the part of the guiding inclined surface 221 away from the tube body 210 to the wall surface of the connection opening 101 is larger, which is convenient for the alignment of the adapter tube 200 and the connection opening 101. After the guiding inclined surface 221 contacts the wall surface of the connection opening 101, the guiding inclined surface 221 can guide the connection section 220 to smoothly enter the connection opening 101, effectively improving the assembly efficiency.

[0062] As Figure 4 shown, the solder layer 300 is connected to the outer surface of the tube body 210 and extends to fill the gap between the outer surface of the connection section 220 and the wall surface of the connection opening 101. The adapter tube 200 is welded and fixed to the module body 100 through the solder layer 300. Due to the welding and fixing method, during the welding process, the solder melts into a liquid state and then fills the gap between the outer surface of the connection section 220 and the wall surface of the connection opening 101. The smaller the gap, the more conducive to the migration of the liquid solder under the capillary action, improving the filling rate of the solder between the outer surface of the connection section 220 and the wall surface of the connection opening 101, and further improving the welding stability, so that the adapter tube 200 and the module body 100 are not easily separated. In this case, the end of the connection section 220 of the adapter tube 200 is provided with a guiding inclined surface 221. Under the guiding action of the guiding inclined surface 221, the adapter tube 200 can quickly and smoothly enter the connection opening 101, which can not only meet the small-gap requirement of welding, improve the welding quality, but also facilitate alignment and improve the assembly efficiency.

[0063] The outer surface of the connection section 220 further includes a connection surface 222. The connection surface 222 is connected between the guiding inclined surface 221 and the outer surface of the tube body 210. The connection section 220 is inserted into the connection opening 101. The solder extends to fill the gap between the connection surface 222 and the wall surface of the connection opening 101 and is connected to the connection surface 222 and the wall surface of the connection opening 101 after the solder solidifies.

[0064] The embodiment of the present application sets a guide slope 221, under the guidance of the guide slope 221, the connection section 220 can be smoothly inserted into the adapter opening 101, thereby improving the assembly efficiency. At the same time, the gap between the connection surface 222 and the wall of the adapter opening 101 can be made smaller, which is convenient for the solder to be evenly and efficiently dispersed in the gap between the connection surface 222 and the wall of the adapter opening 101, and the distance between the connection surface 222 and the wall of the adapter opening 101 can be shortened, thereby enhancing the supporting force of the module body 100 on the connection section 220 and improving the welding quality. Specifically, as Figure 4 As shown, in a first direction M perpendicular to the central axis H of the connecting section 220 , the gap between the connecting surface 222 and the wall surface of the adapter opening 101 is A, and A satisfies: 0 mm≤A≤0.1 mm.

[0065] The connecting surface 222 of the connecting section 220 is connected to the outer surface of the pipe body 210 (specifically, connected to the transition slope 211 described below). In the direction of the central axis H of the connecting section 220, the outer contour size and shape of the part of the connecting section 220 having the connecting surface 222 remain unchanged, so that the connecting section 220 can be smoothly inserted into the adapter opening 101. At the same time, it helps to improve the insertion stability of the connecting section 220 in the adapter opening 101, and also helps to evenly distribute the solder between the connecting surface 222 and the wall of the adapter opening 101, thereby improving the structural strength.

[0066] like Figure 4 As shown, the guiding slope 221 has a first guiding edge 2211 away from the pipeline body 210, and the guiding slope 221 also has a second guiding edge connected to the connecting surface 222. Figure 4 MM direction shown), the distance between the first guide edge 2211 and the wall of the transfer opening 101 is the largest, and the distance between the second guide edge and the wall of the transfer opening 101 is the smallest. The vertical distance between the first guide edge 2211 and the central axis of the connecting section 220 is s1, and the caliber of the transfer opening 101 is R1, wherein 0.05mm≤R1-s1≤1.00mm. By selecting the difference between R1 and s1 within this range, the end where the first guide edge 2211 of the connecting section 220 is located has a large caliber difference with the transfer opening 101, which is convenient for alignment, and under the guiding action of the guiding slope 221, it is convenient for the connecting section 220 to be plugged into the transfer opening 101 more smoothly and efficiently, and prevent the inconvenience of plugging due to the small gap when the connecting section 220 has only the connecting surface 222.

[0067] like Figure 5As shown, a first angle α is formed between the guide slope 221 and the extension line of the connection surface 222, and α satisfies: 0°<α≤30°. When the first angle α is within this range, the inclination of the guide slope 221 is appropriate, which facilitates the smooth insertion of the connection section 220 into the adapter opening 101. When the first angle α is greater than 30°, the guide slope 221 is too steep, which easily leads to the end of the connection section 220 having too small an axial dimension in the connection section 220. When the guide slope 221 contacts the wall surface of the adapter opening 101, the connection section 220 is prone to slipping under a slight external force, which is not convenient for alignment and affects the assembly efficiency.

[0068] During welding, the solder can be arranged around the periphery of the junction between the pipe body 210 and the connecting section 220, so that when the connecting section 220 is inserted into the adapter opening 101, the solder can be supported by the module body 100, and after the solder is hot-melted, it flows to fill the gap between the connecting portion and the wall surface of the adapter opening 101. In addition, the solder is arranged around the periphery of the transition pipe section in a whole circle, so that after the solder solidifies to form a solder layer 300, the adapter tube 200 can be fixed to the module body 100, and the gap between the adapter tube 200 and the wall surface of the adapter opening 101 can be sealed.

[0069] The solder layer 300 is also connected to the outer surface of the pipe body 210 , and can be used to increase the connection area between the solder layer 300 and the adapter tube 200 , thereby increasing the structural strength of the adapter tube 200 installed on the module body.

[0070] Optionally, in the flow direction of the fluid in the flow channel of the pipe body 210 , the outer diameter of the pipe body 210 remains unchanged, or the outer diameter of the portion of the pipe body 210 connected to the connecting section 220 gradually decreases.

[0071] like Figure 4 and Figure 5As shown, the outer surface of the pipe body 210 includes a transition slope 211, and the distance from the transition slope 211 to the central axis D of the pipe body 210 gradually increases from the connecting section 220 toward the pipe body 210. The transition slope 211 is used to limit the depth of the connecting section 220 inserted into the adapter opening 101, and to limit the relative position of the adapter tube 200 and the module body 100 in the axial direction of the adapter opening 101. During assembly, the connecting section 220 can be inserted into the adapter opening 101 first, and then the solder is arranged around the periphery of the junction between the pipe body 210 and the connecting section 220, and then the welding is performed to fix; or, the solder can be arranged around the periphery of the junction between the pipe body 210 and the connecting section 220, and then the connecting section 220 is inserted into the adapter opening 101, and then the welding is performed to fix. It is understandable that during the welding process, various materials are affected by the stress of thermal expansion and contraction, gravity and other forces, which may cause the position of the adapter tube 200 relative to the module body to change. Due to the existence of the transition bevel 211, the position of the adapter tube 200 relative to the module body can be limited, thereby limiting the depth of the adapter tube 200 inserted into the adapter opening 101, preventing the adapter tube 200 from being inserted too deep into the adapter opening 101.

[0072] The solder layer 300 is connected to the transition slope 211, and the transition slope 211 can guide the liquid solder after hot melting to flow to the gap between the outer surface of the connecting section 220 and the wall surface of the transfer opening 101. Figure 4 and Figure 5 As shown, in the flow direction of the internal fluid of the pipe body 210, the inner diameter of the pipe body 210 and the inner diameter of the connecting section 220 remain unchanged. Further, the flow channel inside the pipe body 210 and the flow channel inside the connecting section 220 are coaxially arranged. In this case, the existence of the transition bevel 211 makes the transition bevel 211 and the outer surface of the connecting section 220 form an angle, and the solder layer 300 is connected to the transition bevel 211, and extends through the connection between the transition bevel 211 and the outer surface of the connecting section 220 to the gap between the outer surface of the connecting section 220 and the wall surface of the transfer opening 101, so that the solder layer 300 can form a good wrapping of the transition between the pipe body 210 and the connecting section 220, improve the structural strength, and prevent the transfer tube 200 from breaking.

[0073] The pipeline body 210 includes a main pipe body and a transition section connected to the main pipe body. The outer surface of the transition section includes a transition inclined surface 211. The part of the main pipe body adjacent to the transition section is a straight pipe, and the part of the outer surface of the main pipe body adjacent to the transition section forms the outer wall surface of the main pipe. The transition inclined surface 211 has a first transition edge connected to the outer surface of the connection section 220 and a second transition edge connected to the outer wall surface of the main pipe. The perpendicular distance from the first transition edge to the central axis D of the pipeline body 210 is m, and the perpendicular distance from the second transition edge to the central axis of the pipeline body 210 is n. Wherein, 0.50mm ≤ n - m ≤ 2.00mm. Within this range, the wall thicknesses of the transition section, the main pipe body, and the connection section 220 are appropriate, enabling the adapter pipe 200 to have good structural strength.

[0074] As Figure 5 shown, a transition angle β is formed between the transition inclined surface 211 and the extension line of the outer surface of the pipeline body 210. β satisfies: 30° ≤ β ≤ 60°. For example, β can be 30°, 35°, 45°, 50°, 60° or any range between the two. By selecting the transition angle β within the range of 30° to 60°, the inclination angle range of the transition inclined surface 211 is appropriate, which helps to guide the fluid to flow smoothly into the gap between the outer surface of the connection section 220 and the wall surface of the adapter opening 101. At the same time, the wall thickness ratio ranges of the transition section, the main pipe body, and the connection section 220 are appropriate, enabling the connection between the pipeline plate body 210 and the connection section 220 to have good structural strength.

[0075] As Figure 4 shown, the module body 100 includes an adapter flange 110. The adapter flange 110 has an adapter opening 101. The adapter flange 110 has a flange end face 1101. The flange end face 1101 is angularly connected to the wall surface of the adapter opening 101. The solder layer 300 is filled in the gap between the flange end face 1101 and the outer surface of the pipeline body 210, providing support for the connection between the connection section 220 and the pipeline body 210 and increasing the structural strength of the adapter pipe 200 installed on the template body.

[0076] When the solder layer 300 is filled in the gap between the outer surface of the connection section 220 and the wall surface of the adapter opening 101, specifically, the solder layer 300 fills at least the gap between the connection surface 222 of the connection section 220 and the wall surface of the adapter opening 101 defined by the adapter flange 110. Wherein, the part of the connection section 220 having the connection surface 222 can be entirely within the adapter opening 101, or, due to the presence of the solder layer 300, it can also be set that the part of the connection section 220 having the connection surface 222 and away from the pipeline body 210 extends into the adapter opening 101, and the part adjacent to the pipeline body 210 extends out of the adapter opening 101, that is, the connection section 220 partially enters the adapter opening 101.

[0077] The portion of the solder layer 300 that enters the transfer opening 101 may be filled only in the gap between the wall surface of the transfer opening 101 and the connection surface 222.

[0078] Furthermore, the solder layer 300 can further extend to fill the gap between the guiding inclined surface 221 and the module body 100. For example, the connecting section 220 only extends into the transfer opening 101, and the solder layer 300 extends to fill the gap between the guiding inclined surface 221 and the wall surface of the transfer opening 101; or, the module body 100 further includes a transfer convex portion 120, the transfer convex portion 120 defines a receiving cavity 102, the transfer flange 110 protrudes from the outer surface of the transfer convex portion 120 and defines a transfer opening 101 communicating with the receiving cavity 102, the connecting section 220 passes through the transfer opening 101 and extends into the receiving cavity 102, and the solder layer 300 extends to fill the gap between the guiding inclined surface 221 and the wall surface of the receiving cavity 102.

[0079] Optionally, in the direction of the central axis of the connecting section 220, the length of the portion of the solder layer 300 filled in the gap between the module body 100 and the connecting section 220 is a, and the height of the transfer flange 110 is b, where 0.8 ≤ a / b ≤ 1.2. Within this ratio range, the solder layer 300 connecting the connecting section 220 and the transfer flange 110 can make the two have good installation stability.

[0080] Optionally, the height b of the transfer flange 110 satisfies: 1 mm ≤ b ≤ 3 mm. Within this range, the transfer flange 110 can have a sufficient effective area to connect with the solder layer 300, effectively limit the transfer pipe 200, improve the connection stability, and improve the assembly efficiency.

[0081] In the embodiment of the present application, the module body 100 includes a plurality of transfer convex portions 120 and a plurality of transfer flanges 110 correspondingly protruding from each transfer convex portion 120. That is, the module board body has a plurality of receiving cavities 102 and transfer openings 101 communicating with the corresponding receiving cavities 102. Optionally, adjacent two receiving cavities 102 are arranged at intervals, and the fluid can enter the receiving cavity 102 through the corresponding transfer opening 101, be reversed, and then flow out from other transfer outlets.

[0082] As Figure 6As shown, the module body 100 includes a first plate body 11 and a second plate body 12 which are hermetically connected. The first plate body 11 includes a first flat portion 112 and a first convex portion 111 protruding from the first flat portion 112.
