Technical Field

[0001] This utility model relates to the field of thermal management technology, specifically to an integrated component for vehicles. Background Technology

[0002] The thermal management integrated component includes a connecting pipe that connects the refrigerant flow paths of two interface sections. Since the connecting pipe needs to carry high-pressure refrigerant, it is usually made of rigid metal tubing. However, the interface section is located in a complex position, and it is difficult to assemble the two interface sections by connecting them with rigid metal tubing. It is difficult to ensure the installation position accuracy requirements of the connecting pipe and the interface section, and leakage is prone to occur at the connection. Utility Model Content

[0003] The purpose of this application is to provide an integrated component that optimizes the structure of the receiver component and improves the problem of leakage that easily occurs at the connection of the receiver component.

[0004] This application discloses an integrated component including a compressor, a fluid assembly, and a connecting pipe assembly.

[0005] The integrated assembly provided by the technical solution of this application includes a compressor, a fluid assembly, and a connecting pipe assembly. The first connecting portion and the second connecting portion of the connecting pipe assembly are respectively connected to the first interface portion of the compressor and the second interface portion of the fluid assembly. The connecting pipe assembly's connecting pipe portion connects the first connecting portion and the second connecting portion. The connecting pipe portion includes a bend with a corrugated section. The corrugated section has a certain elasticity and is easier to bend than a rigid straight pipe. The relative position of the first connecting portion and the second connecting portion in the connecting pipe assembly can be adjusted by the degree of bending of the corrugated section of the bend. Thus, the positional accuracy between the corresponding connecting portion and the interface portion is easy to adjust during assembly, reducing the risk of leakage between the corresponding connecting portion and the interface portion. In addition, the corrugated section of the bend can withstand a large amplitude of mechanical vibration, preventing the vibration of the compressor in the integrated assembly from causing the connecting pipe assembly connection to fail, thereby reducing the risk of leakage between the corresponding connecting portion and the interface portion.

[0006] This application discloses an integrated component, including a flow channel component and a connecting pipe assembly. The flow channel component has a refrigerant flow channel and includes a first interface portion and a second interface portion. The connecting pipe assembly includes a connecting pipe portion, a first connecting portion, and a second connecting portion. The connecting pipe portion connects the first connecting portion and the second connecting portion. The first connecting portion is fixedly connected to or limitedly connected to the first interface portion, and the second connecting portion is fixedly connected to or limitedly connected to the second interface portion. The connecting pipe portion has a corrugated pipe section.

[0007] The integrated component provided by the technical solution of this application includes a flow channel component and a connecting pipe assembly. The first interface portion and the second interface portion of the flow channel component are respectively connected to the first connecting portion and the second connecting portion of the connecting pipe assembly. The connecting pipe assembly has a connecting pipe section with a certain degree of elasticity. Compared with a rigid straight pipe, the corrugated pipe section is easier to bend, thereby making it easier to adjust the relative position of the first connecting portion and the second connecting portion in the connecting pipe assembly. As a result, the positional degree between the corresponding connecting portion and the interface portion is easy to adjust during the assembly process, reducing the risk of leakage at the connection between the connecting pipe assembly and the flow channel component.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the scope of the utility model.

[0019] refer to Figures 1 to 3 This application provides an integrated component for a vehicle's thermal management system, including a pipe assembly 2, a first interface portion 11, and a second interface portion 12. The pipe assembly 2 has a refrigerant pipe for flowing refrigerant. The pipe assembly 2 includes a pipe portion 22, a first connecting portion 211, and a second connecting portion 212. The pipe portion 22 connects the first connecting portion 211 and the second connecting portion 212. The first connecting portion 211 is fixedly connected to or limited by the first interface portion 11, and the second connecting portion 212 is fixedly connected to or limited by the second interface portion 12. The fixed connection includes connection methods that restrict disassembly and separation, such as welding, bonding, and riveting. The limited connection includes fastener connections. The connection uses detachable fastening methods such as snap-fit ​​and limiting contact. The first interface portion 11 has a first interface 110 facing the first connecting portion 211 of the pipe assembly 2. The second interface portion 12 has a second interface 120 facing the second connecting portion 212 of the pipe assembly 2. The channel containing the first interface 110 and the channel containing the second interface 120 both connect to a refrigerant pipe. The center lines of the first interface 110 and the second interface 120 are parallel, intersecting, or not in the same plane. The pipe assembly 22 has a corrugated pipe section 23. Specifically, the pipe assembly 22 includes a bend 24, which has the corrugated pipe section 23. (Reference) Figure 1 and Figure 2 In some embodiments of this application, the integrated component includes a compressor 3 and a flow channel component 4. The compressor 3 is fixedly connected or limitedly connected to the flow channel component 4. The flow channel component 4 has a refrigerant flow channel. A first interface portion 11 is located on the compressor 3. The compressor 3 has an inlet 301 and an outlet 302. At least one of the inlet 301 and the outlet 302 is located on the first interface portion 11. A second interface portion 12 is located on the flow channel component 4. At least one of the inlet 301 and the outlet 302 is connected to the refrigerant flow channel 40 through a connecting pipe assembly 2. (Refer to...) Figure 1 The air inlet 301 is located at the first interface portion 11, and the centerline of the air inlet 301 is parallel or nearly parallel to the centerline of the second interface 120 of the corresponding second interface portion 12. (Refer to...) Figure 2 The air inlet 301 is located in the first interface section 11, and the center line of the air inlet 301 is not parallel to the center line of the second interface 120 of the corresponding second interface section 12. In addition, the exhaust port 302 is also located in another first interface section 11, and the center line of the exhaust port 302 intersects with the center line of the second interface 120 of the corresponding second interface section 12. Of course, the solution of this application is not limited to the connection between the compressor 3 and the flow channel component 4 through the above-mentioned connecting pipe assembly 2. It is also applicable to the connection between the compressor and other fluid components such as heat exchanger, liquid receiver, and gas-liquid separator through the above-mentioned connecting pipe assembly 2, or the connection between any two of the flow channel component 4, heat exchanger, liquid receiver and gas-liquid separator through the above-mentioned connecting pipe assembly 2. In the above embodiments, the first interface 110 and the second interface 120 that need to be connected are restricted by the positions of the first interface portion 11 and the second interface portion 12. In addition, since the connector assembly 2 is mostly or entirely made of metal, it is difficult to guarantee the positional accuracy between the first interface portion 11 and the second interface portion 12 corresponding to the first connecting portion 211 and the second connecting portion 212 of the connector assembly 2. A corrugated pipe section 23 is provided in the connector portion of the connector assembly 2. The corrugated pipe section 23 is easy to bend. By providing the corrugated pipe section 23 in the bend portion 24 of the connector portion 22, the corrugated pipe section in the bend portion 24 can pass through. The bending deformation of section 23 significantly adjusts the positions of the first connecting part 211 and the second connecting part 212, ensuring they meet the positional accuracy requirements for connection with the corresponding interface parts. This avoids refrigerant leakage caused by positional misalignment, improving the production yield rate, and facilitates assembly, thus accelerating the production cycle. Furthermore, the corrugated pipe section 23 can absorb vibrations from compressor operation and vehicle movement, preventing the rigid pipe connection between the first interface part 11 and the second interface part 12 from failing under vibration conditions, thereby reducing the risk of leakage between the corresponding connecting parts and interface parts. In this embodiment, the connecting pipe part 22 is made of metal, and both the bent pipe part 24 and the corrugated pipe section 23 are made of metal, possessing a certain degree of hardness and deformation resistance. The bent pipe part 24 with the corrugated pipe section 23 is pre-processed, making its bending degree easier to adjust compared to a straight corrugated pipe section 23.

[0020] In addition, in other implementations, refer to Figure 3 The integrated component includes a flow channel component 4, which has a refrigerant flow channel 40. Since the flow channel component 4 may not be suitable for arranging flow channels between two interfaces that need to be connected, or where space is limited, it is connected via the aforementioned connecting pipe assembly 2. The connecting pipe assembly 2 has a corrugated pipe section 23 at its connecting part 22. The flow channel component 4 includes a first interface section 11 and a second interface section 12. Along the thickness direction of the flow channel component 4, the projection of a portion of the wall forming the refrigerant flow channel 40 overlaps with the projection of the connecting pipe section 22. The corrugated pipe section has a certain degree of elasticity and is easier to bend than a rigid straight pipe, thus facilitating the adjustment of the relative positions of the first and second connecting parts in the connecting pipe assembly. This makes it easier to adjust the positional accuracy between the corresponding connecting parts and interface sections during assembly, reducing the risk of leakage at the connection between the connecting pipe assembly and the flow channel component.

[0021] refer to Figure 1 and Figure 3 The connecting section 22 includes a bent section 24, a first straight section 251, and a second straight section 252. In this embodiment, the corrugated pipe section 23 is a pipe fitting with a corrugated or sawtooth pattern on its wall after being cut along the plane containing its center line. The first straight section 251 and the second straight section 252 are smooth straight pipes, distinct from the corrugated pipe section 23. Since the piping of the integrated components in the vehicle refrigerant system needs to withstand a certain refrigerant pressure, in this embodiment, only a section of the connecting section 22 uses a corrugated pipe section. Considering the processing cost, pressure resistance, and ease of connection with the corresponding connecting part, a straight pipe is chosen for the part connected to the corresponding connecting part. Specifically, the first straight section 251 is connected to the first connecting part 211, and the second straight section 252... 52 connects to the second connecting part 212, and the bend 24 connects the first straight pipe part 251 and the second straight pipe part 252. The bend 24 has a corrugated pipe section 23. In this embodiment, the starting and ending positions of the bend 24 are the starting bends of the first straight pipe part 251 connected to the first connecting part 211 and the starting bends of the second straight pipe part 252 connected to the second connecting part 212. Therefore, the bend 24 can have a partially straight corrugated pipe or a straight smooth round pipe. The corrugated pipe section 23 on the bend 24 makes it easy to adjust the bending angle of the pipe fitting where the bend 24 is located, and adjust the positions of the first connecting part 211 and the second connecting part 212 to meet the positional requirements for connection with the corresponding interface part. Further, in this embodiment, the bend 24 has a first bending section 241 and a second bending section 242. One end of the first bending section 241 is connected to the first straight pipe part 251, and one end of the second bending section 242 is connected to the second straight pipe part 252. (Refer to...) Figure 5In some embodiments, the bellows section 23 connects the first bend section 241 and the second bend section 242, and the bellows section 23 can adjust the relative position between the first bend section 241 and the second bend section 242, for reference. Figure 4 In some embodiments, the first bending section 241 has a bellows section 23, or the second bending section 242 has a bellows section 23, or both bending sections have a bellows section 23. The bellows section 23 can change the degree of bending of the two bending sections, and can adjust the position of the first connecting part 211 and the second connecting part 212 to a greater extent, reducing the assembly difficulty of the pipe assembly.

[0022] Further reference Figure 3 , Figure 4 and Figure 6 The plane containing the centerline of the first bending segment 241 is defined as the first plane P1, and the plane containing the centerline of the second bending segment 242 is defined as the second plane P2. Considering that the centerlines of the pipe bending segments are not regularly bent in one direction and may be spatially distorted, the first plane P1 and the second plane P2 defined above are both planes that are approximately coplanar with the centerlines of their respective bending segments. In other words, the planes on which the centerlines of the first bending segment 241 and the second bending segment 242 are mostly located are the first plane P1 and the second plane P2, respectively. The first plane P1 and the second plane P2 have an angle. When the two planes have an angle, it means that the bending directions of the corresponding first bending segment 241 and the second bending segment 242 are not consistent. The arrangement of the first bending segment 241 and the second bending segment 242 in this embodiment differs from that in the previous embodiment. Figure 3 In the embodiment shown, the first bending segment 241 and the second bending segment 242 are arranged as described above, and the center line of the associated first straight pipe section 251 intersects or is not in the same plane as the center line of the second straight pipe section 252. In this case, the bending direction of the first bending segment 241 and the second bending segment 242 can be easily adjusted at multiple angles in space, and the extension direction of the pipe section can be adjusted to a greater extent, ensuring the positional accuracy between the connecting part and the interface part, and reducing the assembly difficulty of the pipe assembly.

[0023] refer to Figure 1 , Figure 4 and Figure 7In this embodiment, the orientation of the first interface 110 is the same as that of the second interface 120, which is equivalent to the connection surface of the first interface 11 and the connection surface of the second interface 12 being parallel. In this way, on the one hand, the pipe assembly is easier to install, and on the other hand, the position of the connection part and the interface part is easier to adjust. In addition, in this embodiment, the first plane P1 is perpendicular to or nearly perpendicular to the second plane P2, or the angle between the first plane P1 and the second plane P2 is greater than 80 degrees, or the center line of the first straight pipe 251 and the center line of the second straight pipe 252 are perpendicular to each other or perpendicular to each other in space. In this way, the two curved sections and the pipe section connecting the two curved sections are roughly in a three-coordinate form, and the relative position of the two ends of the pipe assembly 2 is easier to adjust.

[0024] refer to Figures 4 to 9 The connector assembly 2 includes a connecting section 26 and a fixing part 27. Specifically, at least one of the first connecting part 211 and the second connecting part 212 includes the connecting section 26 and the fixing part 27. The connecting section 26 has at least one circumferentially arranged annular groove 260 for placing a seal. The fixing part 27 is fixedly connected to the corresponding interface part. The connecting section 26 and the fixing part 27 are integrally structured, or the connecting section 26 and the connector part 22 are integrally structured.

[0025] refer to Figure 4 In one embodiment of this application, the connector assembly 2 includes a connecting block 28. Specifically, at least one of the first connecting portion 211 and the second connecting portion 212 includes the connecting block 28. The connecting block 28 includes an integrally formed connecting segment 26 and a fixing portion 27. The fixing portion 27 has a connector cavity 280 with an opening facing the connector portion 22. The connector portion 22 includes a straight pipe portion 25 corresponding to the first connecting portion 211 and the second connecting portion 212, namely, a first straight pipe portion 251 or a second straight pipe portion 252. For ease of description, the first... Straight pipe section 251 and second straight pipe section 252 are collectively referred to as straight pipe section 25. One end of straight pipe section 25 is connected to corrugated pipe section 23, and the other end of straight pipe section 25 is located in pipe cavity 280. Straight pipe section 25 is welded and fixed to fixing part 27. This arrangement makes the connection between connecting block 28 and pipe section 22 more reliable and reduces the risk of refrigerant leakage. The connecting section 26 on connecting block 28 and fixing part 27 are machined and integrally formed, making the connection between connecting block 28 and interface part more stable, reducing the risk of refrigerant leakage, and reducing the assembly difficulty of pipe assembly. In this embodiment, fixing part 27 has a through connecting hole 270 for accommodating fasteners. Fixing part 27 and corresponding interface part are connected by fasteners.

[0026] In another embodiment of this application, at least one of the first connecting part 211 and the second connecting part 212 includes a pressure block 29, the connecting part 22 includes a straight pipe part 25, one end of the straight pipe part 25 is connected to a corrugated pipe section 23, and the other end of the straight pipe part 25 is connected to a connecting section 26, and a fixing part 27 is located on the pressure block 29. The connecting section 26, the straight pipe part 25 and the corrugated pipe section 23 are integrally formed, and the fixing part 27 is separate from the connecting section 26. Along the axial direction of the connecting section 26, the fixing part 27 abuts against and limits the connecting section 26. The connecting section 26 is integrally extruded with the straight pipe part 25 and the corrugated pipe section 23. The connecting section 26, like the straight pipe part 25 and the corrugated pipe section 23, has a thin-walled structure. On the one hand, this makes the entire integrated component lighter, and on the other hand, it reduces the welding process, making the manufacturing of the connecting part component 2 simpler.

[0027] Specifically, the connecting section 26 includes a first extrusion part 261 and a second extrusion part 262. The first extrusion part 261 is formed by expanding the diameter of the straight tube part 25 through extrusion molding, and the second extrusion part 262 is formed by expanding the diameter of the straight tube part 25 through extrusion molding. Along the central axis of the connecting section 26, the first extrusion part 261 and the second extrusion part 262 are circumferentially arranged. The first extrusion part 261 is located away from the port of the connecting section 26 relative to the second extrusion part 262. Along the axis of the connecting section 26, an annular groove 260 is located between the first extrusion part 261 and the second extrusion part 262. The first extrusion part 261 abuts against the pressure block 29 for axial positioning. On the one hand, the forming of the connecting section 26 is simple, requiring less material and reducing its manufacturing cost. On the other hand, the walls of the annular grooves used to house the rubber sealing ring are all extruded thin-walled structures. After the pressure block is pressed, the walls of the annular grooves can further slightly compress the sealing element, absorbing some positional tolerances and ensuring the sealing performance at the connection between the connecting section and the interface part. (Reference) Figure 8 and Figure 9 It also has a third extrusion section 263, which has two annular grooves for placing the seals to further ensure its sealing performance.

[0028] refer to Figure 8 and Figure 9To ensure that the extruded portion of the thin-walled structure does not deform significantly and affect the sealing performance, the first extrusion portion 261 includes a base 2611 and a protrusion 2612. An annular groove 260 is located between the second extrusion portion 262 and the base 2611. The protrusion 2612 is located away from the port of the connecting section 26 relative to the base 2611. The protrusion 2612 is enlarged and extruded relative to the base 2611. The pressure block 29 has a groove 291 with a through groove 290 open on one side. The straight tube Part 25 is located in the through groove 290. The groove part 291 has a receiving groove 2910 with an opening facing the protrusion 2612 on the side near the first extrusion part 261. The protrusion 2612 is at least partially located in the receiving groove 2910. Along the axial direction of the connecting section 26, one side of the protrusion 2612 abuts against the bottom wall 2911 of the receiving groove 2910, and the other side of the protrusion 2612 abuts against the corresponding interface part. The outer peripheral wall of the protrusion 2612 abuts against or has a gap with the inner side wall 2912 of the receiving groove 2910. The limiting between the connecting section 26 and the interface section is achieved by an additional extruded protrusion, which avoids large deformation of the wall of the annular groove, thus reducing its sealing performance. A stepped receiving groove 2910 is provided in the groove section 291. The inner side wall 2912 and bottom wall 2911 of the receiving groove 2910 limit the protrusion 2612, strengthen the protrusion 2612, and prevent the protrusion 2612 from undergoing large deformation.

[0029] It should be noted that the above description uses specific examples to illustrate the principle and implementation of this utility model. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
