Figures 1-29The integrated component 100 includes a connecting portion 10 and a liquid storage portion 20, which are connected as a whole. The connecting portion 10 has channels, including a first channel 111 and a second channel 112, which are independently arranged. The integrated component 100 has a liquid storage chamber 30, which can store liquid working medium. The first channel 111 has a first inlet 1111, a first outlet 1112, and / or a third outlet 1113 formed on the outer surface of the wall of the connecting portion 10. The working medium enters the first channel 111 from the first inlet 1111, and at least part of the working medium leaves the first channel 111 through the first outlet 1112 and / or the third outlet 1113. The liquid storage chamber 30 can communicate with the second channel 112. Channel 112 forms a second outlet 1121 on the outer surface of the wall of connecting part 10. Connecting part 10 has a mounting seat, which communicates with the first channel 111 or the second channel 112. This allows components in the thermal management system to be located on the mounting seat. These components include valve parts and sensors, and the thermal management system includes components such as valve parts, second valve parts, first check valves, and second check valves. Sensors may include first temperature sensors and second temperature sensors. In this technical solution, connecting part 10 provides multiple interfaces and mounting seats for assembling the integrated component with the vehicle thermal management system. It also assembles with the liquid storage part to realize the liquid storage function, facilitating the assembly of the integrated component and simplifying the assembly process. In addition, the integrated component has a simple and compact structure and does not require additional connecting pipes. In the following embodiments, the multiple interfaces include a first inlet 1111, a first outlet 1112, and subsequent second inlets, second outlets 1121, third inlets, and third outlets 1113. The mounting seat may include a first mounting seat 41 and a second mounting seat 42. The first inlet 1111 can be connected to the compressor outlet in the thermal management system, the first outlet 1112 can be connected to the inlet of the indoor condenser, the second inlet can be connected to the outlet of the indoor condenser, and the second outlet 1121 can be connected to the inlet of the intermediate heat exchanger. During the docking process with the system, the connecting part 10 can provide connection support, such as setting a stud at the interface position, with one end fixed to the connecting part 10 and the other end protruding from the surface of the connecting part 10, to facilitate docking with the system piping. The connecting part 10 can include two limiting parts 1100, with the first outlet 1112 and the third outlet 1113 formed in the limiting parts 1100, and the limiting parts can support and limit the valve core 72 of the valve part.

[0037] See Figures 1-12In a first embodiment of the integrated component, the integrated component 100 includes a first valve portion 70, a second valve portion 80, a connecting portion 10, and a liquid storage portion 20. The connecting portion 10 has channels, including a first channel 111 and a second channel 112, which are independently arranged. The integrated component 100 has a liquid storage chamber 30. The first channel 111 has a first inlet 1111, a first outlet 1112, and a third outlet 1113 formed on the outer surface of the wall of the connecting portion 10. The working medium enters the first channel 111 from the first inlet 1111, exits the first channel 111 through the first outlet 1112 and the third outlet 1113, and the liquid storage chamber 30 can be directly connected to the second channel 112. The channel 112 forms a second outlet 1121 on the outer surface of the wall of the connecting part. The connecting part 10 has a mounting seat, which includes a first mounting seat 41 and a second mounting seat 42. Both the first mounting seat 41 and the second mounting seat 42 are connected to the first channel 111.

The first valve part 70 and the second valve part 80 are two-way valves. By controlling the first valve part 70, the working medium pressure between the first inlet 1111 and the first outlet 1112 can be changed; by controlling the second valve part 80, the working medium pressure between the first inlet 1111 and the third outlet 1113 can be changed. Of course, the integrated component may also include only one valve section, that is, the first temperature regulating valve 70 and the second temperature regulating valve 80 as a whole. The valve section is a three-way valve, and at least part of the valve section is located in the mounting base and between the first outlet 1112 and the third outlet 1113.

[0040] The sensing head of the first temperature sensor 61 is located in the third channel 113. The first temperature sensor 61 is fixedly connected to the connecting part 10. The sensing head of the first temperature sensor 61 is located between the second inlet 1131 and the first one-way valve 51. The first temperature sensor can detect the temperature of the working medium entering the liquid storage chamber.

[0041] To facilitate the assembly and connection of the integrated components and the system, the first inlet 1111 and the second outlet 1121 are located on the same side of the connecting part 10. Specifically, the first inlet 1111 and the second outlet 1121 are located at the top of the connecting part 10 and between the first valve part 70 and the second valve part 80. The first outlet 1112 and the second inlet 1131 are located on the same side of the side wall of the connecting part 10. The third inlet 1141 and the third outlet 1113 are located on the same side of the side wall of the connecting part 10. In this way, the interfaces of the integrated components are arranged in pairs, which is conducive to the connection of the joints of the thermal management system in pairs and facilitates assembly.

The first segment 1102 and the second segment 1122 are intersecting, or in other words, the first segment 1102 and the second segment 1122 are connected. The first segment 1102 is perpendicular to the liquid collecting pipe 21, and the second segment 1122 is parallel to the liquid collecting pipe 21. In this embodiment, the structure of the liquid collecting pipe 21 is relatively simple, while the second channel 112 is relatively complex. In this embodiment, the connecting part 10 can be made of profile. In order to process the first segment 1102, the first segment 1102 is connected to the outer periphery of the connecting part 10. In order to prevent leakage of the working medium, a plug 91 is provided.

[0043] See Figure 12 The liquid collecting pipe 21 includes a first sub-section 211, a second sub-section 212, and a transition section 213.

The weld between the housing 24 and the cylindrical part 12 is at a set distance from the main body part, so as to avoid the influence of welding heat on the mounting components of the connecting part 10. The mounting components include a first one-way valve, a second one-way valve, and a first temperature sensor. The inlets of the third channel 113 and the fourth channel 114 in the liquid storage cavity 30 are located between the central axis of the liquid storage cavity 30 and the inner wall of the cylindrical part 12. Specifically, the inlets of the third channel 113 and the fourth channel 114 in the liquid storage cavity 30 are located at the midpoint between the central axis of the liquid storage cavity 30 and the inner wall of the cylindrical part 12.

The valve core 72 is spherical and has a valve core channel 721. The drive section 71 can drive the valve core 72 to rotate. The valve core channel 721 connects the first orifice 111.

The on / off state of the first orifice 111 can also be adjusted. There can also be only one valve section, which can be a three-way ball valve.
