[0019] The features and exemplary embodiments of various aspects of the present invention are described below. To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below with reference to the accompanying drawings and specific embodiments. In this document, relational terms such as "first" and "second" are used merely to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.

[0020] An embodiment of the present invention provides an integrated component that can be applied to a vehicle thermal management system or an air-conditioning system, and in particular, can be applied to a refrigerant circulation circuit of a vehicle, and of course can also be applied to a coolant circulation circuit of a vehicle.

[0021] Specifically, refer to Figures 1 to 6 An embodiment of the present application provides an integrated component, including a flow channel component 100, the flow channel component 100 having a first flow channel 1, a second flow channel 2 and a confluence channel 3, the fluid in the first flow channel 1 and the fluid in the second flow channel 2 converge in the confluence channel 3, the confluence channel 3 is understood to be the intersection area of the fluids, and the shape of the confluence channel 3 is not limited. In the drawings of this embodiment, the confluence channel is illustrated by a rectangular area, and it can also be other shapes, such as a flow channel with a similar shape to the first flow channel 1 and the second flow channel 2, or a hole, a chamber, etc. The first flow channel 1 and the second flow channel 2 are respectively connected to the confluence channel 3. Specifically, the wall forming the confluence channel 3 has a first communication port 10 and a second communication port 20. In this embodiment, the first communication port 10 is the fluid outlet of the first flow channel 1, and the second communication port 20 is the fluid outlet of the second flow channel 2. The first communication port 10 connects to the first flow channel 1, the first communication port 10 connects to the confluence channel 3, and the second communication port 20 connects to the second flow channel 2. The integrated assembly includes a first detection element 41. In this embodiment, the first detection element 41 is fixedly connected to the flow channel assembly 100. The first detection element 41 is capable of detecting fluid parameters in the first flow channel 1 or the second flow channel 2. Specifically, the first detection element 41 includes a sensor, further including a flow sensor, a temperature sensor, a pressure sensor, and a temperature and pressure sensor. The fluid parameters in the first flow channel 1 and the second flow channel 2 are generally inconsistent. During the fluid convergence process, if the fluid in one flow channel impacts and enters the other flow channel, the measurement data of the first detection element 41 will fluctuate significantly, affecting the measurement accuracy of the first detection element 41.

[0022] The flow blocking portion 30 is located in the confluence channel 3. The flow blocking portion 30 is fixedly connected to the wall forming the confluence channel 3 or is an integral structure, that is, the flow blocking portion is connected to the wall of the confluence channel as a separate component, or the wall forming the confluence channel 3 includes the flow blocking portion 30; the flow blocking portion 30 can be understood as an obstacle for blocking the fluid. The shape of the flow blocking portion 30 is not limited. In the embodiment, the attached Figures 1 to 6 In the figure, the flow barrier 30 is illustrated as a straight wall, but it can also be of other shapes. The first communication port 10 faces the flow barrier 30; and / or the second communication port 20 faces the flow barrier 30. The first communication port 10 facing the flow barrier 30 is not limited to the first communication port 10 directly facing the flow barrier 30. The flow barrier can be at a certain angle to the central axis of the first communication port 10, and the same applies to the second communication port 20. The central axis of the first communication port 10 represents the normal to the plane in which the first communication port 10 is located and passes through the center of the first communication port. That is, in the direction of fluid flow of the first communication port 10, the flow barrier 30 is provided to prevent the fluid flowing out of the first communication port 10 from entering the second flow channel 2 through the second communication port 20, and / or in the direction of fluid flow of the second communication port 20, the flow barrier 30 is provided to prevent the fluid flowing out of the second communication port 20 from entering the first flow channel 1 through the first communication port 10, thereby reducing fluid interference between the first flow channel 1 and the second flow channel 2, thereby improving the accuracy of the detection element used to detect fluid parameters in the flow channels. The number of the blocking portion 30 can be one or more, with the same blocking portion 30 blocking the fluid flow of the two communication ports, or multiple blocking portions 30 blocking the fluid flow of the two communication ports respectively, or one blocking portion 30 blocking the fluid flow of one communication port.

[0023] refer to Figure 3In one embodiment of the present application, the wall forming the confluence channel 3 includes a channel wall portion 30', the first connecting port 10 and the second connecting port 20 are located in the channel wall portion 30', and along the direction of the line connecting the center of the first connecting port 10 and the center of the second connecting port 20, the blocking portion 30 is located between the first connecting port 10 and the second connecting port 20. The blocking portion 30 and the wall forming the confluence channel 3 are an integral structure, and the fixed connection includes welding, riveting, screw connection, etc. The integral structure includes the blocking portion 30 and the wall forming the confluence channel 3 being integrally cast, forged, injection molded, etc. The blocking portion 30 has a first blocking surface 3001 and a second blocking surface 3002, the first connecting port 10 faces the first blocking surface 3001, and the second connecting port 20 faces the second blocking surface 3002. In this embodiment, the first wall portion 31 and the second wall portion 32 are arranged opposite to each other, and the first flow blocking surface 3001 and the second flow blocking surface 3002 are arranged back to back. Of course, in other embodiments, the first connecting port 10 and the second connecting port 20 are not directly opposite each other, and the normal of the plane where the first connecting port 10 is located may be at a certain angle to the normal of the plane where the second connecting port 20 is located, which may be an obtuse angle. In this case, the fluid interference between the two flow channels is more serious, and the flow blocking portion 30 is required to block it, reduce the fluid interference between the two flow channels, and improve the accuracy of the detection element used to detect the fluid parameters of the flow channels.

[0024] In other embodiments of the present application, reference is made to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 It is preferred that the first communicating port 10 and the second communicating port 20 are not arranged to be directly opposite to each other to reduce the fluid interference between the two flow channels. The wall forming the confluence channel 3 includes a flow blocking portion 30. Along the central axis direction of the first communicating port 10, the projection of the wall forming the first communicating port 10 overlaps with the projection of the flow blocking portion 30. Along the central axis direction of the second communicating port 20, the projection of the wall forming the second communicating port 20 overlaps with the projection of the flow blocking portion 30. Of course, in other embodiments, along the central axis direction of the communicating port, the projection of the wall of the communicating port may not overlap with the projection of the flow blocking portion. The flow blocking portion 30 is configured to prevent the fluid in the first communicating port from directly interfering with the fluid in the second communicating port.

[0025] Further, refer to Figure 1In one embodiment of the present application, the wall forming the converging channel 3 includes a flow blocking portion 30, the flow blocking portion 30 includes a first flow blocking portion 301 and a second flow blocking portion 302, the first communication port 10 is located in the first flow blocking portion 301, the second communication port 20 is located in the second flow blocking portion 302, the second flow blocking portion 302 has a first flow blocking surface 3001, the first flow blocking portion 301 has a second flow blocking surface 3002, the first communication port 10 faces the first flow blocking surface 3001, and the second communication port 20 faces the second flow blocking surface 30 02, in this embodiment, the first flow blocking portion 301 is opposite to the second flow blocking portion 302, and the first flow blocking portion 301 and the second flow blocking portion 302 are both one of the walls forming the converging channel 3. A portion of the first flow blocking portion 301 has the first communication port 10, and another portion has a second flow blocking surface 3002 for fluid blocking the second communication port 20. Similarly, a portion of the second flow blocking portion 302 has the second communication port 20, and another portion has the first flow blocking surface 3001 for fluid blocking the first communication port 10. In other embodiments, there may be only one flow blocking surface, see Figure 2 A first flow blocking portion 301 is provided at the outlet of the converging channel and is located on the opposite side of the second flow blocking portion 302. The first flow blocking portion 301 does not have a second flow blocking surface 3002. At this time, the fluid interference between the two flow channels can also be reduced, and the accuracy of the detection element used to detect the flow channel fluid parameters can be improved.

[0026] In addition to the above-mentioned situation where the normal line of the plane where the first communication port 10 is located is parallel to the normal line of the plane where the second communication port 20 is located and staggered with each other, in another embodiment, the normal line of the plane where the first communication port 10 is located is at a right angle or an acute angle to the normal line of the plane where the second communication port 20 is located. In this case, the fluid interference between the two flow channels is relatively mild compared to the above-mentioned situation, and the part of the wall forming the confluence channel can be directly used as the flow blocking part. Figure 4 The walls forming the confluence channel 3 include a first wall portion 31, a second wall portion 32, a first flow blocking portion 301 and a second flow blocking portion 302. The first wall portion 31 is opposite to the first flow blocking portion 301, and the second wall portion 32 is opposite to the second flow blocking portion 302. The first connecting port 10 is located in the first wall portion 31, and the second connecting port 20 is located in the second wall portion 32. The first connecting port 10 faces the first flow blocking portion 301, and the second connecting port 20 faces the second flow blocking portion 302.

[0027] In another embodiment, reference Figure 5 The wall forming the confluence channel 3 includes a channel wall portion 30 ′ and a flow blocking portion 30 . The channel wall portion 30 ′ is arranged opposite to the flow blocking portion 30 . The first connecting port 10 and the second connecting port 20 are both located in the channel wall portion 30 ′, and the flow blocking portion 30 is opposite to the second connecting port 20 .

[0028] Further, refer to Figure 7The first flow channel 1 and the second flow channel 2 are not directly connected to the confluence channel, but are connected through the first channel 101 and the second channel 102, which is conducive to reducing the flow resistance of the two flow channels and thus reducing the fluid interference between the two flow channels. Specifically, the flow channel assembly 100 has a first channel 101 and a second channel 102. The first channel 101 connects the first flow channel 1 and the confluence channel 3, and the second channel 102 connects the second flow channel 2 and the confluence channel 3. The first connecting port 10 is located at one end of the first channel 101, and the second connecting port is located at one end of the second channel 102. The axis of the first channel 101 is parallel to the axis of the second channel 102. The parallel arrangement of the first channel 101 and the second channel 102 requires the fluid in one flow channel to rotate 180 degrees before entering the other flow channel, which is conducive to reducing the fluid interference between the two flow channels and thus improving the accuracy of the detection element used to detect the flow channel fluid parameters.

[0029] Furthermore, in this embodiment, referring to Figures 7 to 9 In order to facilitate the arrangement of the first flow channel 1 and the second flow channel 2 and the molding of the first channel 101 and the second channel 102, the wall forming the first flow channel 1 includes a first flow channel wall 11, and the wall forming the second flow channel 2 includes a second flow channel wall 12. The first flow channel wall 11 has a third communication port 10', and the second flow channel wall 12 has a fourth communication port 20'. The third communication port 10' is located at the end of the first channel 101 away from the first communication port 10, and the fourth communication port 20' is located at the end of the second channel 102 away from the second communication port 20. The first flow channel wall 11 and the second flow channel wall 12 have a third communication port 10'. The flow channel walls 12 are coplanar. In addition, in this embodiment, the flow channel assembly 100 includes a partition wall 5. Along the line connecting the center of the first connecting port 10 and the center of the second connecting port 20, the partition wall 5 is located between the first connecting port 10 and the second connecting port 20. The wall forming the first connecting port 10 is located on the partition wall 5, and the wall forming the second connecting port 20 is located on the partition wall 5. This embodiment is not only conducive to the arrangement of the first flow channel 1 and the second flow channel 2 and the molding and processing of the first channel 101 and the second channel 102, but also provides a solution for the arrangement and molding of more flow channels.

[0030] Further, refer to Figures 6 to 8 and Figure 10In this embodiment, the wall forming the first flow channel 1 includes a third flow channel wall 13, and the wall forming the second flow channel 2 includes a fourth flow channel wall 14. The third flow channel wall 13 and the fourth flow channel wall 14 are coplanar, wherein the partition wall 5 extends from the third flow channel wall 13 and the fourth flow channel wall 14 facing the confluence channel 3 to form the end wall of the first flow channel 1 and the second flow channel 2, forming the first flow channel wall 11 and the third flow channel wall 13 opposite to each other. Specifically, the first flow channel wall 11 and the third flow channel wall 13 are parallel and opposite to each other, and the flow channel assembly 100 includes a valve interface portion 61, and the valve port portion is an integral structure with the third flow channel wall 13. The valve interface portion 61 has a valve channel 6, and the third flow channel wall 13 There is a channel opening 60 connected to the valve channel 6, and the axis of the valve channel 6 is consistent with the axis of the first channel 101. In this embodiment, the channel opening 60 of the valve channel 6 is the outlet of the valve, and the fluid passing through the valve first enters the first flow channel 1 through the channel opening 60 of the valve channel 6. However, since the axis of the valve channel 6 is consistent with the axis of the first channel 101, that is, the channel opening 60 is directly opposite to the first connecting port 10 and the third connecting port 10', there is no drainage of the fluid at the channel opening 60 in the first flow channel 1, but the fluid at this valve outlet directly enters the confluence channel 3, which will not cause fluid interference to the first flow channel and the second flow channel, and thus will not cause interference to the accuracy of the detection element.
