A flow channel 35 is disposed on the first plate portion 31 and / or the second plate portion 32. Both the first plate portion 31 and the second plate portion 32 have grooves forming the flow channel 35. Both the first liquid storage portion 61 and the second liquid storage portion 62 have grooves forming the liquid storage cavity 65. The first plate portion 31 and the first liquid storage portion 61 are integral structures, and the second plate portion 32 and the second liquid storage portion 62 are integral structures. In an optional embodiment, the first liquid storage part 61 has a groove forming a liquid storage cavity 65, the second liquid storage part 62 has a flat plate structure, the first liquid storage part 61 and the second liquid storage part 62 are sealed together, and the first liquid storage part 61 and the second liquid storage part 62 cooperate to form at least a partial liquid storage cavity 65.

[0042] Reference Figure 8 and Figure 9 The first plate portion 31 includes a first wall 311 facing the second plate portion 32. Along a direction perpendicular to the first wall 311, the first plate portion 31 has a groove extending from the first wall 311 away from the second wall 321. The second plate portion 32 includes a second wall 321 facing the first plate portion 31. Along a direction perpendicular to the second wall 321, the second plate portion 32 has a groove and a hole extending from the second wall 321 away from the first wall 311. The first wall 311 and the second wall 321 are fixedly connected, and the first plate portion 31 and the second plate portion 32 cooperate to form at least a partial flow channel 35. The flow channel portion 30 reduces pipe connections and the risk of fluid leakage in the pipes. The flow channel portion 30 is formed by stamping sheet metal, which simplifies the product structure, facilitates manufacturing, reduces assembly difficulty, and lowers costs compared to the complex interconnections of multiple pipes.

[0043] Specifically, in this embodiment, the first plate portion 31 and the first liquid storage portion 61 are integral structures, and the second plate portion 32 and the second liquid storage portion 62 are integral structures. The first plate portion 31 and the first liquid storage portion 61 are formed by stamping from the same sheet metal. Stamping along the thickness direction of the sheet metal forms a first wall 311 and a portion protruding outward from the first wall 311, wherein the inner cavity of the protruding portion is part of the flow channel 35 of the flow channel portion 30; stamping along the thickness direction of the sheet metal also forms a first face portion 613 and a portion protruding outward from the first face portion 613, wherein the inner cavity of the protruding portion is part of the liquid storage cavity 65 of the liquid storage portion 60. The second plate portion 32 and the second liquid storage portion 62 are also formed by stamping from another sheet metal. Stamping along the thickness direction of the sheet metal forms a second wall 321 and a portion protruding outward from the second wall 321, wherein the inner cavity of the protruding portion is another part of the flow channel 35 of the flow channel portion 30. The sheet metal is stamped along its thickness direction, forming a second face 621 and an outwardly protruding portion from the second face 621. The inner cavity of the outwardly protruding portion forms another part of the liquid storage cavity 65 of the liquid storage section 60. Optionally, the first face 613 and the second face 621 are fixedly connected by brazing, and the first wall 311 and the second wall 321 are fixedly connected by brazing. In an optional embodiment, the first plate section 31 and the first liquid storage section 61 are formed by stamping from the same sheet metal, and the second plate section 32 and the second liquid storage section 62 are separate structures. The first plate section 31 and the second plate section 32 cooperate to form at least a partial flow channel 35, and the first liquid storage section 61 and the second liquid storage section 62 cooperate to form at least a partial liquid storage cavity 65.

[0044] In some possible embodiments, the flow channel portion 30 may further include a third plate and a fourth plate, which are arranged along the thickness direction H of the flow channel portion. The first plate portion 31 and the second plate portion 32 cooperate to form a part of the flow channel 35 of the flow channel portion 30, and the third plate and the fourth plate cooperate to form another part of the flow channel 35 of the flow channel portion 30. The first plate portion 31, the second plate portion 32, the third plate and the fourth plate cooperate with each other to form the flow channel 35 of the flow channel portion 30. Optionally, the flow channel portion 30 may include the first plate portion 31, the second plate portion 32, the third plate, the fourth plate... the Nth plate. No specific limitation is made here. The selection is made according to actual needs. Multiple stamping plates cooperate with each other to form the flow channel 35 of the flow channel portion 30.

[0045] In some possible embodiments, the flow channel portion 30 is a one-piece structure, having grooves and / or holes forming the flow channel 35. This one-piece structure reduces welding steps, and directly creating grooves and / or holes in the flow channel portion 30 helps reduce the risk of fluid leakage.

[0046] Reference Figure 8 and Figure 9 The liquid storage section 60 includes a base plate 67. The first liquid storage section 61 and the second liquid storage section 62 are both sealed to the base plate 67. The filter assembly 66 is connected to the base plate 67. The liquid storage chamber 65 is at least partially located between the first liquid storage section 61, the second liquid storage section 62, and the base plate 67. The liquid storage section 60 includes a first inlet 63 and a second inlet 64. The inner cavities of the first inlet 63 and the second inlet 64 are respectively connected to the liquid storage chamber 65. The inner cavities of the first inlet 63 and the second inlet 64 are respectively connected to different sections of the flow channel 35. The first inlet 63 is farther from the base plate 67 than the second inlet 64.

[0047] Reference Figure 8 , Figure 9 and Figure 14 The liquid storage section 60 includes a connecting pipe 610, which is at least partially located in the liquid storage chamber 65. The filter assembly 66 includes a body 661 and a filter screen 662, which is connected to the body 661. One end of the connecting pipe 610 is fixedly connected to the first port 63, and the other end of the connecting pipe 610 is connected to the body 661. The lumen of the connecting pipe 610 communicates with the inner cavity of the filter assembly 66, and the inner cavity of the filter assembly 66 communicates with the liquid storage chamber 65 through the perforated space of the filter screen 662.

[0048] Specifically, the filter assembly 66 also includes a cover 663 and a bracket 664. The body 661 includes a connecting hole 665. The cover 663 is connected to the body 661, and the bracket 664 is connected to the cover 663. A connecting tube 610 has a portion located in the channel of the connecting hole 665. One end of the connecting tube 610 is fitted with the bracket 664 for limiting engagement. After the other end of the connecting tube 610 is inserted into the channel of the connecting hole 665, it is fitted with the bracket 664 for limiting engagement. The filter screen 662 is annular. Optionally, the cover 663 and the body 661 are detachably connected for easy replacement of the filter screen 662. Optionally, the cover 663 and the body 661 are welded together.

[0049] In some possible embodiments, refer to Figures 8 to 10The liquid storage section 60 includes an insert 68. The first liquid storage section 61 and the second liquid storage section 62 are both sealed to the insert 68. The insert 68 is at least partially located within the cavity of the first opening 63. The insert 68 has a communicating channel 681, which connects the flow channel 35 and the liquid storage cavity 65. A connecting pipe 610 is fixedly connected to the insert 68. A portion of the connecting pipe 610 is located within the communicating channel 681, and the lumen of the connecting pipe 610 communicates with the communicating channel 681. The insert 68 is fitted into the first opening 63 and has a generally funnel-shaped structure, which facilitates a sealed connection.

[0050] The liquid storage section 60 includes a sealing ring 69, and an insert 68 has a circumferential groove 682. The sealing ring 69 is sleeved on one end of the connecting pipe 610, and is located between the insert 68 and the connecting pipe 610. The sealing ring 69 is at least partially located in the cavity of the circumferential groove 682, and abuts against the groove wall of the circumferential groove 682 and the pipe wall of the connecting pipe 610. Since it is difficult to directly seal the connecting pipe 610 to the first opening 63, the insert 68 makes it relatively easy to seal the connecting pipe 610 to the first opening 63, and the sealing ring 69 can enhance the sealing performance of the connection between the connecting pipe 610 and the insert 68.

[0051] In some possible embodiments, refer to Figures 8 to 14 The liquid storage section 60 includes a first baffle 611 and a second baffle 612, both located in the liquid storage chamber 65. Both baffles 611 and 612 are fixedly connected to the connecting pipe 610. The first baffle 611 and 612 are spaced apart along the axial direction of the connecting pipe 610, with the first baffle 611 being further away from the bottom plate 67 than the second baffle 612. The first baffle 611 has a first through hole 6111, which extends through the first baffle 611 along its thickness direction. A portion of the connecting pipe 610 is located within the first through hole 6111. The second baffle 612 has a second through hole 6121, which extends through the second baffle 612 along its thickness direction. A portion of the connecting pipe 610 is located within the second through hole 6121. Optionally, the wall of the first through hole 6111 is welded and fixed to the wall of the connecting pipe 610, and the wall of the second through hole 6121 is welded and fixed to the wall of the connecting pipe 610. In an optional embodiment, the liquid storage section 60 includes only the first baffle 611; in an optional embodiment, the liquid storage section 60 includes only the second baffle 612. No specific limitation is made here; the choice is made according to the actual situation.

[0052] Reference Figure 11 and Figure 13The first baffle 611 has a plurality of first holes 6112, which penetrate the first baffle 611 along its thickness direction. The second baffle 612 has a plurality of second holes 6122, which penetrate the second baffle 612 along its thickness direction. The arrangement of the first holes 6112 and the second holes 6122 allows for effective flow of fluid in the liquid storage chamber 65.

[0053] In some possible embodiments, refer to Figures 8 to 14 The connecting pipe 610 includes a first rib 6101 and a second rib 6102. The first rib 6101 and the second rib 6102 are fixedly connected to the connecting pipe 610. Optionally, the first rib 6101 and the connecting pipe 610 are integrally formed, and the second rib 6102 is integrally formed with the connecting pipe 610. The first rib 6101 is connected to the first baffle 611. The setting of the first rib 6101 can enhance the stability of the connection between the first baffle 611 and the connecting pipe 610. The first rib 6101 has a certain limiting effect on the first baffle 611, reducing the possibility of the first baffle 611 being displaced in the axial direction of the connecting pipe 610. The second rib 6102 is connected to the second baffle 612. The second rib 6102 enhances the stability of the connection between the second baffle 612 and the connecting pipe 610. The second rib 6102 also has a certain limiting effect on the second baffle 612, reducing the possibility of displacement of the second baffle 612 in the axial direction of the connecting pipe 610. In an optional embodiment, the first rib 6101 and the connecting pipe 610 are separate structures, and the second rib 6102 and the connecting pipe 610 are also separate structures.

[0054] In some possible embodiments, the liquid storage section 60 includes a drying package located between a first baffle 611 and a second baffle 612. The drying package abuts against the connecting pipe 610. Optionally, both the first baffle 611 and the second baffle 612 abut against the drying package, providing a certain limiting effect on the drying package and reducing the possibility of displacement of the drying package in the axial direction of the connecting pipe 610. Optionally, the drying package abuts against the wall of the liquid storage chamber 65. The wall of the connecting pipe 610 and the wall of the liquid storage chamber 65 together provide a certain limiting effect on the drying package, reducing the possibility of displacement of the drying package in the radial direction of the connecting pipe 610. Optionally, the drying package and the connecting pipe 610 are secured together with cable ties.

[0055] Specifically, the fluid stored and circulated in the liquid storage chamber 65 of the liquid storage section 60 is a refrigerant, which can be R134a, CO2, or other forms of refrigerant. The flow process of the fluid between the flow channel section 30 and the liquid storage section 60 is as follows: the fluid in the flow channel section 30 flows into the liquid storage chamber 65 of the liquid storage section 60 through the channel of the second opening 64 of the liquid storage section 60, flows through the drying pack, is dried and absorbs water by the drying pack, and then flows through the inner cavity of the filter assembly 66. After the filter screen 662 filters out impurities in the fluid, it flows through the cavity of the connecting pipe 610 and flows back to the flow channel 35 of the flow channel section 30 through the first opening 63 of the liquid storage section 60, and so on.

[0056] In related technologies, a fluid management component includes a connecting block, a flow channel section, and at least two valve assemblies. The flow channel section includes a first plate section and a second plate section, and the flow channel section has a flow channel located in the first plate section and / or the second plate section. The connecting block has multiple internal flow channels and mounting cavities. The connecting block is connected to the flow channel section, and at least two valve assemblies are connected to the connecting block. The connecting block is an integral structure and can only connect valve assemblies that are compatible with the connecting block. If different types of valve assemblies are to be connected, the internal structure of the connecting block needs to be adapted. The fluid management component has poor applicability and a relatively limited application scenario. (For ease of understanding, the feature names in related technologies adopt the technical feature names in this application. For ease of distinction, the technical features in related technologies are not labeled.)

[0057] Reference Figure 6 and Figure 7 The fluid management assembly includes a flow channel portion 30, at least two valve body portions 20, and at least two valve assemblies 40. The flow channel portion 30 includes a first plate portion 31 and a second plate portion 32, and the flow channel portion 30 has a flow channel disposed in the first plate portion 31 and / or the second plate portion 32. A portion of the valve assembly 40 is located within the inner cavity of the valve body portion 20, and the valve assembly 40 is sealed to the valve body portion 20. At least two valve body portions 20 are respectively connected to the flow channel portion 30, and a gap exists between adjacent valve body portions 20.

[0058] Compared to related technologies, the fluid management component includes at least two valve body sections 20, with a gap between adjacent valve body sections 20. The adjacent valve body sections 20 are relatively independent, allowing for compatibility with various types of valve assemblies 40, thus improving the applicability of the fluid management component and expanding its application scenarios. Furthermore, the gap between adjacent valve body sections 20 and their spaced arrangement reduce the possibility of heat transfer, thereby reducing harmful heat loss in the fluid management device.

[0059] The valve body 20 is a standardized component, with each valve body 20 having a roughly identical structure. Similarly, the valve assembly 40 is also a standardized component, with each valve assembly 40 having a roughly identical structure, although the detailed structure can be adjusted according to specific requirements. In this application, the use of standardized valve assemblies 40 and valve body 20 facilitates product standardization, reduces the number of molds required, lowers costs, simplifies product structure, facilitates manufacturing, and reduces assembly difficulty.

[0060] Reference Figure 6 The flow channel portion 30 includes at least two mounting portions 33, which are located on the same side of the width direction W of the flow channel portion and are arranged linearly and spaced apart. The valve body portion 20 is connected to the mounting portions 33. A portion of the valve body portion 20 is sealed to a first plate portion 31, and another portion of the valve body portion 20 is sealed to a second plate portion 32. A portion of the valve body portion 20 is accommodated in the mounting cavity of the mounting portion 33. A portion of the structure of the first plate portion 31 is formed into a portion of the structure of the mounting portion 33 by stamping, and a portion of the structure of the second plate portion 32 is formed into another portion of the structure of the mounting portion 33 by stamping. The two are welded together to form the mounting portion 33.

[0061] Reference Figure 6 and Figure 7 The fluid management assembly also includes a control assembly 10, which includes a first housing 11, a second housing 12, and a circuit board 13. The first housing 11 and the second housing 12 are sealed together. The control assembly 10 has an assembly cavity 14 located between the first housing 11 and the second housing 12. The circuit board 13 is located in the assembly cavity 14, and the valve assembly 40 is at least partially located in the assembly cavity 14. The valve body 20 is connected to the second housing 12. Optionally, both the first housing 11 and the second housing 12 are made of plastic, which has the advantages of being lightweight, easy to shape, and having good insulation. The circuit board 13 is electrically and / or signal connected to the valve assembly 40. The circuit board 13 includes a control chip mounted on the circuit board 13, which is used to control the operation of the valve assembly 40.

[0062] In some possible embodiments, refer to Figure 6 and Figure 7 The fluid management assembly also includes a connecting block 15, which is connected to the second housing 12. At least two valve body portions 20 are respectively connected to the connecting block 15. The connecting block 15 and the valve body portions 20 are both integral structures. The connection block 15 simplifies the assembly of the valve body portions 20 with the second housing 12. Without the connecting block 15, the valve body portions 20 would be directly assembled with the second housing 12, which would be difficult. The connecting block 15, through its positioning and transfer function, reduces the assembly difficulty of the valve body portions 20 with the second housing 12.

[0063] Reference Figure 6and Figure 19 The valve assembly 40 includes a connecting portion 46 and a valve core portion 47. The circuit board 13 and the valve core portion 47 are fixed to and electrically connected to the connecting portion 46. The valve core portion 47 includes a housing portion 471 and a valve needle 472. One end of the housing portion 471 engages with the circuit board 13 or the second housing 12, and the other end of the housing portion 471 engages with the valve body portion 20. The valve needle 472 is at least partially located in the inner cavity of the housing portion 471, and the valve needle 472 is movable along the axial direction of the valve assembly 40.

[0064] In this application, the valve assembly 40 includes mechanical parts but not electrical control parts. The electrical control parts that control the movement of the valve assembly 40 are all located in the control assembly 10. Optionally, the connection parts 46 of all valve assemblies 40 are fixed and electrically connected to the same circuit board 13, and the electrical control parts corresponding to all valve assemblies 40 are located on the same circuit board 13. Controlling all valve assemblies 40 through the circuit on a single circuit board 13 can improve integration, facilitate the miniaturization of the control assembly 10, and optimize the control logic.

[0065] It should be understood that the control component 10, a valve component 40 and a valve body 20 together can realize the function of an expansion valve or a solenoid valve. The structure of the valve needle 472 corresponding to the expansion valve and the solenoid valve is different, and the corresponding valve needle 472 structure can be selected according to the system requirements.

[0066] Reference Figures 15 to 19 The valve body 20 includes a main body 26, a first interface 27, and a second interface 28. The first interface 27 and the second interface 28 are respectively connected to the main body 26. The main body 26 has a receiving cavity 261, the first interface 27 has a first channel 271, and the second interface 28 has a second channel 281. A portion of the housing 471 is located within the receiving cavity 261. When the valve assembly 40 is in a first state, the first channel 271 and the second channel 281 are isolated at the valve needle 472. When the valve assembly 40 is in a second state, the first channel 271 and the second channel 281 are connected. The control chip controls the movement path of the valve needle 472 along the axial direction of the valve assembly 40, thereby controlling not only the connection and isolation between the first channel 271 and the second channel 281, but also the flow rate of the fluid between the first channel 271 and the second channel 281.

[0067] Reference Figure 6 and Figure 19The valve assembly 40 also includes a stator assembly 48 and a rotor assembly 49. The stator assembly 48 is sleeved on the outside of the rotor assembly 49, with a gap between them. The valve needle 472 is located inside the rotor assembly 49. When the stator assembly 48 is energized, it generates a magnetic field. This magnetic field causes some components of the rotor assembly 49 to rotate, and these rotating components drive the valve needle 472 to move up and down. The stator assembly 48 is located in the assembly cavity 14 and is fixed to the second housing 12. The connecting part 46 is fixed to and electrically connected to the stator assembly 48. Part of the rotor assembly 49 is located in the assembly cavity 14, and another part is located in the receiving cavity 261. The rotor assembly 49 is fixedly connected to the valve body part 20.

[0069] Reference Figure 8 and Figure 9 The flow channel portion 30 includes a first connecting port portion 341 and a second connecting port portion 342, which are located on the same side of the thickness direction H of the flow channel portion. It should be noted that the number of connecting ports 34 can be multiple, and no specific limitation is made here; the number can be selected according to the actual situation.

[0070] Reference Figure 1 , Figure 8 and Figure 9 The fluid management component includes a heat exchanger 70, with a first connection port 341 and a second connection port 342 both connected to the heat exchanger 70. In this embodiment, the heat exchanger 70 is a battery cooler. Integrating the heat exchanger 70 through the flow channel portion 30 improves the integration of the fluid management component. Optionally, the fluid management component also includes a compressor and an intermediate heat exchanger. The compressor, intermediate heat exchanger, and heat exchanger 70 are all located on the same side of the thickness direction H of the flow channel portion, further improving the integration of the fluid management component while saving space and improving installation efficiency. The fluid management component can also integrate other external components, selected according to system requirements. The flow channel portion 30 is provided with connection ports 34 that mate with these external components.

All valve body parts 20 are oriented in the same direction, which helps to save space, improve installation efficiency, and reduce costs.

[0074] The first valve assembly 41, the second valve assembly 42, the third valve assembly 43, the fourth valve assembly 44, and the fifth valve assembly 45 are each electrically connected to the same circuit board 13. One control component 10 controls the operation of all five valve assemblies 40 simultaneously. This improves integration and facilitates the miniaturization of the control component 10 and the optimization of the control logic.

[0075] In some possible embodiments, the fluid management component includes N valve body sections 20, each fixedly connected to a flow channel section 30, and N valve assemblies 40 corresponding one-to-one with the N valve body sections 20. The N valve assemblies 40 are electrically connected to the same circuit board 13, and a control component 10 simultaneously controls the operation of the N valve assemblies 40. The number of valve body sections 20 and valve assemblies 40 is not specifically limited here and can be selected according to system requirements. Optionally, the N valve assemblies 40 are electrically connected to the N circuit boards 13, and each valve assembly 40 has an independent control module. The independent control module controls the movement of the corresponding valve assembly 40, which facilitates the standardization of control modules and improves the situation where all valve assemblies 40 cannot work due to damage or failure of the control component 10.

[0076] Reference Figure 6 , Figures 15 to 18 The valve body portion 20 includes an extension portion 29, which extends peripherally from the side of the main body portion 26 near the control assembly 10. By providing the extension portion 29, the valve body portion 20 can improve the connection reliability between the valve body portion 20 and the second housing 12, and also limit the distance between two adjacent valve body portions 20, reducing installation difficulty and improving assembly accuracy.
