Detailed Implementation

[0022] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

The singular forms “a,” “the,” and “the” used in this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0024] It should be understood that the terms "first," "second," and similar terms used in this application specification and claims do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, "a" or "one," and similar terms do not indicate a quantity limitation, but rather indicate the presence of at least one; "multiple" indicates two or more. Unless otherwise stated, terms such as "front," "rear," "lower," and / or "upper" are for illustrative purposes only and are not limited to a location or spatial orientation. Terms such as "comprising" or "including" indicate that the elements or objects preceding "comprising" encompass the elements or objects listed following "comprising" or "including" and their equivalents, but do not exclude other elements or objects.

[0025] The fluid management component of an exemplary embodiment of this application will now be described in detail with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations may complement or combine with each other.

[0026] According to one possible embodiment of the fluid management component of this application, referring to 1 to Figure 13 As shown, a fluid management component 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 31 and a second plate 32. The flow channel portion 30 has a channel disposed on the first plate 31 and / or the second plate 32.

[0027] The valve assembly 40 has a portion located in the inner cavity of the valve body 20. The valve assembly 40 is sealed to the valve body 20. At least two valve bodies 20 are respectively connected to the flow channel 30, and there is a gap between two adjacent valve bodies 20.

[0028] 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.

[0029] 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.

[0030] refer to Figure 7 and Figure 8 Both the first plate 31 and the second plate 32 have grooves and / or holes forming the flow channel portion 30. The first plate 31 includes a first wall 311 facing the second plate 32, and the second plate 32 includes a second wall 321 facing the first plate 31. The first wall 311 and the second wall 321 are fixedly connected. The first plate 31 and the second plate 32 cooperate to form at least a portion of the channel of the flow channel portion 30. Along a direction perpendicular to the first wall 311, the first plate 31 has grooves and / or holes extending away from the first wall 311, and along a direction perpendicular to the second wall 321, the second plate 32 has grooves and / or holes extending away from the second wall 321. The first plate 31 and the second plate 32 are integral structures.

[0031] Specifically, in this embodiment, the first plate 31 and the second plate 32 are formed by sheet metal stamping. Specifically, the sheet metal is stamped along its thickness direction, forming a first wall 311 and a portion protruding outward from the first wall 311, wherein the inner cavity of the outwardly protruding portion is part of the channel of the flow channel 30; the sheet metal is also stamped along its thickness direction, forming a second wall 321 and a portion protruding outward from the second wall 321, wherein the inner cavity of the outwardly protruding portion is another part of the channel of the flow channel 30. Optionally, the first wall 311 and the second wall 321 are fixedly connected by brazing. The arrangement of the flow channel 30 can reduce pipe connections and reduce the risk of fluid leakage in the pipes. At the same time, installing the valve body 20 and the valve assembly 40 on the flow channel 30 is beneficial to improving the integration of the fluid management components. The flow channel 30 is formed by sheet metal stamping, which simplifies the product structure, facilitates manufacturing, reduces assembly difficulty, and also reduces costs compared to the intricate connections of multiple pipes.

[0032] In an optional embodiment, the reference Figure 7 and Figure 8 The flow channel 30 may further include a third plate and a fourth plate, which are arranged along the thickness direction H of the flow channel. The first plate 31 and the second plate 32 cooperate to form a part of the channel of the flow channel 30, and the third plate and the fourth plate cooperate to form another part of the channel of the flow channel 30. The first plate 31, the second plate 32, the third plate and the fourth plate cooperate with each other to form the channel of the flow channel 30. In an optional embodiment, the flow channel 30 may include the first plate 31, the second plate 32, the third plate, the fourth plate... the Nth plate. No specific limitation is made here. The selection is based on actual needs. Multiple stamping plates cooperate with each other to form the channel of the flow channel 30.

[0033] Reference Figure 5 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 31, and another portion is sealed to a second plate 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 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 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.

[0034] Reference Figure 5 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. In an optional embodiment, 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.

[0035] In some possible embodiments, refer to Figure 5The 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.

[0036] Reference Figure 9 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.

[0037] 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 on the control assembly 10. In an optional embodiment, 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 circuits on a single circuit board 13 can improve integration, facilitate the miniaturization of the control assembly 10, and optimize the control logic.

[0038] 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.

[0039] Reference Figures 9 to 13 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, the second interface 28 has a second channel 281, and a portion of the shell 471 is located in the receiving cavity 261.

[0040] When the valve assembly 40 is in the 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 the second state, the first channel 271 and the second channel 281 are connected.

[0041] Reference Figure 5 and Figure 9 The 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.

[0042] Reference Figure 5 and Figure 7 The flow channel section 30 includes at least two connection ports 34, the inner cavity of which communicates with the channel of the flow channel section 30. The connection ports 34 are located on one side of the flow channel section in the thickness direction H, and the valve body section 20 is located on one side of the flow channel section in the width direction W. The fluid management assembly also includes a one-way valve 50, which is located on one side of the flow channel section in the length direction L. The connection ports 34 are arranged in the same direction, which is beneficial for pipeline layout design, reduces space occupation, and facilitates integration. The valve body section 20 is arranged in the same direction, which helps to save space, improve installation efficiency, and reduce costs.

[0043] Reference Figure 1 and Figures 5 to 8 The flow channel section 30 includes a first connecting port 341, a second connecting port 342, a third connecting port 343, and a fourth connecting port 344. The first connecting port 341, the second connecting port 342, the third connecting port 343, and the fourth connecting port 344 are located on the same side of the thickness direction H of the flow channel section. It should be noted that the number of connecting ports 34 can be multiple; no specific limitation is made here, and the selection depends on the actual situation.

[0044] The fluid management assembly also includes a reservoir 60 and a heat exchanger 70. The first connection port 341 and the second connection port 342 are both connected to the reservoir 60, and the third connection port 343 and the fourth connection port 344 are both connected to the heat exchanger 70. In this embodiment, the heat exchanger 70 is a battery cooler. Integrating the reservoir 60 and the heat exchanger 70 through the flow channel 30 improves the integration of the fluid management assembly. Furthermore, since the reservoir 60 and the heat exchanger 70 are both located on the same side of the thickness direction H of the flow channel, it saves space, improves installation efficiency, and reduces costs. In an optional embodiment, the fluid management assembly also includes a compressor and an intermediate heat exchanger. The compressor, intermediate heat exchanger, reservoir 60, and heat exchanger 70 are all located on the same side of the thickness direction H of the flow channel, further improving the integration of the fluid management assembly. The fluid management assembly can also integrate other external components, selected according to system requirements. The flow channel 30 is provided with connection ports 34 that cooperate with these external components.

[0045] Reference Figure 5 and Figure 6 In this embodiment, the fluid management assembly includes a first valve body 21, a second valve body 22, a third valve body 23, a fourth valve body 24, and a fifth valve body 25. These valve bodies are connected to different valve assemblies 40 and to flow channel sections 30. The valve bodies 21, 22, 23, 24, and 25 are arranged linearly and spaced apart, and are also arranged in a line along the length L of the flow channel section. All valve bodies 20 are oriented in the same direction, which helps save space, improves installation efficiency, and reduces costs.

[0046] The fluid management assembly includes a first valve assembly 41, a second valve assembly 42, a third valve assembly 43, a fourth valve assembly 44, and a fifth valve assembly 45. A first valve body 21 is fixedly connected to the first valve assembly 41, a second valve body 22 is fixedly connected to the second valve assembly 42, a third valve body 23 is fixedly connected to the third valve assembly 43, a fourth valve body 24 is fixedly connected to the fourth valve assembly 44, and a fifth valve body 25 is fixedly connected to the fifth valve assembly 45.

[0047] The first valve body 21, the second valve body 22, the third valve body 23, the fourth valve body 24, and the fifth valve body 25 are arranged in a straight line along the length L of the flow channel and are spaced apart. All valve body parts 20 are oriented in the same direction, which helps to save space, improve installation efficiency, and reduce costs.

[0048] 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, facilitates the miniaturization of the control component 10, and promotes the optimization of the control logic.

[0049] In an optional embodiment, 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 actions of the N valve assemblies 40. The number of valve body sections 20 and valve assemblies 40 is not specifically limited and can be selected according to system requirements. In an optional embodiment, the N valve assemblies 40 are electrically connected to 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.

[0050] Reference Figure 5 and Figures 10 to 13 The valve body 20 includes an extension 29, which extends peripherally from the main body 26 near the control assembly 10. The second housing 12 has a first through hole, the connecting block 15 has a second through hole, and the extension 29 of the valve body 20 has a third through hole. The second housing 12, the connecting block 15, and the valve body 20 are fixedly connected by bolts. The bolts include a nut and a shank. The shank passes through the first through hole, the second through hole, and the third through hole. The nut is located on the side of the second housing 12 away from the connecting block 15. By providing the extension 29, the connection reliability between the valve body 20 and the second housing 12 can be improved, and the distance between two adjacent valve body parts 20 can be limited, reducing installation difficulty and improving assembly accuracy.
