[0036] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail 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 such actual relationship or order between these components. The fixed connections or limiting connections described herein include welded, bonded, and threaded connections, while limiting connections include snap-fit ​​connections.

[0037] The fluid control component can be applied to a thermal management system, which can be used in the air conditioning system of new energy vehicles. Of course, the application of the fluid control component in this embodiment is not limited to the description herein, and can also be used in other fields, such as household air conditioning, automotive air conditioning, and energy storage devices. Specifically, the fluid control component is applied to the coolant system of the thermal management system, where coolant circulates, and the coolant can exchange heat with the refrigerant of the thermal management system.

[0038] Example 1:

[0039] One embodiment of this application provides a fluid control component, such as... Figure 1-12As shown, the fluid control assembly includes a flow channel plate assembly 10 and a fluid management unit 2. The fluid management unit 2 is fixedly connected to or limited by the flow channel plate assembly 10. The fluid management unit 2 has a channel for the flow medium or a cavity for storing the flow medium, and the channel or cavity of the fluid management unit 2 communicates with the flow channel of the flow channel plate assembly 10. The fluid management unit 2 includes a control valve and a pump assembly 24. The control valve includes a first valve 21, a second valve 22, and a third valve 23. The control valve includes a valve core, and at least a portion of the valve core is located in the receiving cavity 11a0 of the flow channel plate assembly or the mounting cavity of the second mounting part 13a. In this embodiment, the first valve 21 is an eight-way water valve, specifically a column valve. In other embodiments, the first valve 21 can also be replaced by a five-way water valve, a ten-way water valve, a twelve-way water valve, or other multi-way water valves with other numbers of channels. In this embodiment, the second valve 22 is a three-way water valve, and there are two second valves 22. In other embodiments, the second valve 22 can also be replaced by multi-way water valves with other numbers of channels. In this embodiment, the third valve 23 is a one-way valve, and there are two third valves 23. The third valves 23 are installed on the side of the flow channel plate assembly 10. In other embodiments, the third valves 23 can be installed inside the flow channel of the flow channel plate assembly 10. In this embodiment, there are three pump assemblies 24. The pump assemblies 24 are installed on the same side of the flow channel plate assembly 10. In other embodiments, at least one of the pump assemblies 24 can be installed on another side of the flow channel plate assembly 10, or on the opposite side of the flow channel plate assembly 10. This application does not limit the number of the first valve 21, the second valve 22, the third valve 23, and the pump assembly 24. In other embodiments, different numbers of the first valve 21, the second valve 22, the third valve 23, and the pump assembly 24 can be provided as needed, or at least one of the first valve 21, the second valve 22, the third valve 23, and the pump assembly 24 can be included.

[0040] like Figure 1 As shown, a first direction X, a second direction Y, and a third direction Z are defined. These three directions are mutually perpendicular. The second direction Y is defined as the vertical direction. Therefore, the first direction X and the third direction Z are two directions on a horizontal plane. One direction marked with an arrow is designated as positive, and the opposite direction as negative. For example, in this embodiment, the negative direction of the second direction Y is the direction of gravity. The surface formed by the first direction X and the second direction Y is defined as the first surface S. The third direction Z is the normal direction of the first surface S. In this embodiment, the flow channel plate assembly 10 extends along the first surface S. The flow channel plate assembly 10 has flow channels, including a first flow channel 104 and a second flow channel 105. The flow channels of the flow channel plate assembly 10 also extend along the first surface S. In other words, the flow channel plate assembly 10 has a certain thickness in the third direction Z, and the grooves forming the flow channels are recessed from the sidewall of the flow channel plate assembly 10 along the third direction Z. The first surface S is also a surface parallel to the extending direction of the first flow channel 104.

[0041] like Figure 1 As shown, different fluid management units 2 are installed on different sides of the flow channel plate assembly 10. The flow channel plate assembly 10 includes a first side 101 and a second side 102, which are arranged at an angle, specifically a 90-degree angle. At least a portion of the first side 101 extends along the first surface S. Along the normal direction of the first surface S, a second valve 22, a third valve 23, and a pump assembly 24 are installed on the first side 101, and a first valve 21 is installed on the second side 102. The central axis of the valve core of the first valve 21 is parallel to the first surface S. This arrangement, by appropriately increasing the thickness of the fluid control assembly, can significantly reduce the length and width of the fluid control assembly, making the fluid control assembly structure compact and beneficial for miniaturization. The second valve 22, the third valve 23, and the pump assembly 24 are installed on the first side 101, that is, on the same side of the flow channel plate assembly 10. This is conducive to the compact design of the fluid control assembly in the thickness direction. Compared with the installation requirements of the second valve 22, the third valve 23, and the pump assembly 24, only the installation space needs to be reserved in the first side 101 of the flow channel plate assembly 10.

[0042] Specifically, along the direction of gravity, the pump assembly 24 is installed on the side of the flow channel plate assembly 10. Relatively speaking, the interface of the flow channel plate assembly 10 can be arranged above the pump assembly 24, with at least one interface used to inject coolant into the fluid control assembly. That is, along the direction of gravity, the pump assembly 24 is located below the injection interface, which is beneficial for removing residual air in the pump chamber and improving the operating performance of the pump assembly 24. In this embodiment, the pump assembly 24 includes a first pump 241, a second pump 242, and a third pump 243. The first pump 241, the second pump 242, and the third pump 243 are all installed on the side of the flow channel plate assembly 10, and the first pump 241, the second pump 242, and the third pump 243 are arranged linearly along the first direction X.

[0043] Along the direction of gravity, the second valve 22 and the third valve 23 are mounted above the pump assembly 24. The second valve 22 and the third valve 23 are positioned at the same height. When the second valve 22, the third valve 23, and the pump assembly 24 are mounted on the same first side 101, this arrangement facilitates the miniaturization of the fluid control assembly. In other embodiments, the pump assembly 24 can also be arranged on different sides of the flow channel plate assembly 10. For example, two pumps of the pump assembly 24 can be arranged on the first side 101, and the other pump can be arranged on the opposite side of the first side 101, or one pump can be arranged on the second side 102. The installation height of the pump is lower than the height of the first valve 21 to meet the venting requirements during pump installation.

[0044] The fluid control component is used in the thermal management system. The fluid control component includes an interface 140 for connecting to other devices within the thermal management system, such as... Figure 1 As shown, the flow channel plate assembly 10 includes an interface portion 14, which protrudes from the side wall of the flow channel plate assembly 10. An interface component 140 is welded to the interface portion 14. Other equipment is directly fixedly or partially connected to the interface component 140 via pipelines. The interface component 140 facilitates the connection of other equipment in the thermal management system to the fluid control components. In other embodiments, the interface portion 14 may also be integrally formed with the interface component 140. In this embodiment, as... Figure 2 and Figure 4 As shown, the interface portion 14 is located on the first flow channel plate 11 and the third flow channel plate 13. The first flow channel plate 11 includes the interface portion 14 protruding in the negative direction of the third direction Z, and the third flow channel plate 13 includes the interface portion 14 protruding in the positive direction of the third direction Z. The third flow channel plate 13 also includes other interface portions 14 protruding in the positive direction of the second direction Y. Of course, in other embodiments, the interface portion 14 may also be located on the second flow channel plate 12.

[0045] like Figure 2-13 As shown, the structure of the flow channel plate assembly 10 is described in detail. Figures 2-4 As shown, the flow channel plate assembly 10 includes a first flow channel plate 11, a second flow channel plate 12, and a third flow channel plate 13. The first flow channel plate 11, the second flow channel plate 12, and the third flow channel plate 13 are arranged along a third direction Z. The first flow channel plate 11 is located on one side of the second flow channel plate 12, and the third flow channel plate 13 is located on the opposite side of the second flow channel plate 12. In other words, the third flow channel plate 13 is located on the side of the second flow channel plate 12 away from the first flow channel plate 11. In other embodiments, part of the first flow channel plate 11 may be located on one side of the second flow channel plate 12, and part of the third flow channel plate 13 may be located on the opposite side of the second flow channel plate 12. The first flow channel plate 11 and the second flow channel plate 12 are welded together, and the second flow channel plate 12 and the third flow channel plate 13 are welded together. The three-layer flow channel plate stacking arrangement, while meeting the flow channel connectivity requirements of the flow channel plates, enables the flow channel plate assembly 10 to have a compact structure and occupy little space. In other embodiments, the second flow channel plate 12 may also be integral with at least one of the first flow channel plate 11 and the third flow channel plate 13.

[0046] like Figures 3-13As shown, the first flow channel plate 11 has a first groove 110, the second flow channel plate 12 has a second groove 120 and a fourth groove 120', and the third flow channel plate 13 has a fifth groove 130. The first flow channel plate 11 has a first groove 110 on the side near the second flow channel plate 12, and the first groove 110 is recessed from the sidewall of the first flow channel plate 11 along the normal direction of the first surface S. The second flow channel plate 12 has a second groove 120 on the side near the first flow channel plate 11, and a fourth groove 120' on the side near the third flow channel plate 13. The second groove 120 and the fourth groove 120' are located on opposite sides of the second flow channel plate 12, that is, they are recessed inward from opposite sides of the second flow channel plate 12 along the normal direction of the first surface S to form grooves, at least partially. The second groove 120 and at least part of the fourth groove 120' have a common bottom wall; the third flow channel plate 13 has a fifth groove 130 on the side near the second flow channel plate 12, the fifth groove 130 is recessed from the side wall of the third flow channel plate 13 along the normal direction of the first surface S, the third flow channel plate 13 has a second mounting part 13a on the side away from the second flow channel plate 12, the second mounting part 13a is used to mount the second valve 22, the third valve 23 or the pump assembly 24, the center line of the second mounting part 13a is parallel to the normal of the first surface S, and the opening of the second mounting part 13a faces the positive direction of the third direction Z.

[0047] The flow channel plate assembly 10 has flow channels along a third direction Z, including a first flow channel 104 and a second flow channel 105. A first flow channel plate 11 and a second flow channel plate 12 are welded together. The wall forming the first flow channel 104 includes the walls of the first flow channel plate 11 and the second flow channel plate 12. A first groove 110 forms at least a portion of the first flow channel 104, and a second groove 120 forms at least a portion of the first flow channel 104. A second flow channel plate 12 and a third flow channel plate 13 are welded together. The wall forming the second flow channel 105 includes the walls of the second flow channel plate 12 and the third flow channel plate 13. A fourth groove 120' forms at least a portion of the second flow channel 105, and a fifth groove 130 forms at least a portion of the second flow channel 105. Specifically, the opening of the first groove 110 is opposite to the opening of the second groove 120, and the openings of the fourth groove 120' and the fifth groove 130 are opposite to each other. The welded connection allows the grooves to form at least a portion of the flow channel after welding. In other embodiments, one side may be a groove and the other a flat plate structure, with the flat plate structure covering the opening of the groove to form a partial flow channel. The flat plate can be located at any one of the first flow channel plate 11, the second flow channel plate 12, and the third flow channel plate 13. Specifically, the second flow channel plate 12 with the flat plate structure covers the first groove 110 to form a first flow channel 104. The first flow channel 104 can communicate with the second flow channel 105 through an opening on the flat plate, or communicate with the opening of the interface portion 14 formed on the flow channel portion 11b through an opening on the flow channel portion 11b. In this embodiment, the second flow channel plate 12 has a first hole 12a1, which is a through hole. The opening of a groove in the first groove 110 is opposite to the first hole 12a1. The first flow channel 104 formed by this groove directly penetrates the second flow channel plate 12 and communicates with the second flow channel 105, or communicates with the opening of the interface portion 14 formed on the second flow channel plate 12.

[0048] In this embodiment, the first flow channel plate 11 includes a mounting portion 11a and a flow channel portion 11b, which are integrally formed. Specifically, the first flow channel plate 11 can be integrally injection molded. The first flow channel plate 11 has a receiving cavity 11a0, and the wall forming the receiving cavity 11a0 includes the wall of the mounting portion 11a. At least a portion of the valve core of the first valve 21 is located in the receiving cavity 11a0. The first valve 21 is fixedly connected or limitedly connected to the mounting portion 11a. In this embodiment, the valve cover of the first valve 21 is welded to the mounting portion 11a, and the control portion of the first valve 21 is fixedly connected to the valve cover. In this embodiment, the first valve 21 is a column valve. Correspondingly, the mounting portion 11a includes a cylindrical peripheral wall 11a2 with at least two connecting ports 11a1. The first flow channel plate 11 has at least two first channels 1041, which are part of the first flow channel 104. The first channels 1041 have connecting ports 11a1 on the wall of the mounting portion 11a. In this embodiment, there are eight connecting ports 11a1. Correspondingly, the first groove 110 includes eight non-communicating grooves in the first flow channel plate 11. The connecting ports 11a1 and the first grooves 110 correspond one-to-one, thus connecting the receiving cavity 11a0 with the first grooves 110. By rotating the valve core of the first valve 21, the medium flowing into the receiving cavity 11a0 can be adjusted to flow out through different connecting ports 11a1. That is, rotating the valve core of the first valve 21 can connect at least two first flow channels 104. In other embodiments, the mounting portion 11a can also be used to mount the pump assembly 24.

[0049] The flow channel portion 11b includes staggered plates and has a first groove 110. The staggered plates enclose and form non-communicating first grooves 110, which form at least a portion of the first flow channel 104. At least a portion of the flow channel portion 11b extends along the first surface S. It should be noted that the first flow channel 104 includes a first channel 1041 and an extended flow channel 1042. Compared to the valve body of a typical water valve, the valve body includes a receiving portion and a connecting portion. The receiving portion is used to install the valve core, and the connecting portion is used for mounting and connecting with the flow channel plate. The connecting portion has a channel connecting the receiving cavity of the receiving portion and the flow channel of the flow channel plate. In this embodiment, the first channel 1041 is analogous to the channel of the connecting portion of a typical water valve, and the extended flow channel 1042 refers to the first flow channel 104 extending along the first surface S. In this embodiment, a portion of the first groove 110 forms the first channel 1041, and another portion of the first groove 110 forms the extended flow channel 1042. The wall forming the extended flow channel 1042 includes the wall of the flow channel portion 11b, which is equivalent to a general valve housing integrating the function of the flow channel plate in forming the flow channel, thus diversifying the function of the first flow channel plate 11 on which the first valve 21 is installed. A portion of the flow channel portion 11b includes an interface portion 14 on the side opposite to the first groove 110, which facilitates the connection of the first flow channel 104 located in the flow channel portion 11b to other equipment in the thermal management system through the interface portion 14.

[0050] The flow channel 11b includes a first connecting portion 11b1, and a first channel 1041 has an opening in the first connecting portion 11b1. The second flow channel plate 12 includes a second connecting portion 12b1, and the connection port of the second connecting portion 12b1 communicates with the first channel 1041. The first connecting portion 11b1 and the second connecting portion 12b1 are welded together. Compared with the general water valve and the flow channel plate being bolted together, in this embodiment, the first flow channel plate 11 with the first valve 21 is welded together with the second flow channel plate 12. Specifically, the welding connection of the first connecting portion 11b1 and the second connecting portion 12b1 can save the setting of the sealing ring at the connection part and save the installation process of the bolt connection, which is conducive to reducing the manufacturing cost of the fluid control component.

[0051] The first connecting portion 11b1 is the end wall on the opening side of the first groove 110, similar to the structural design of the flow channel portion 11b of the first flow channel plate 11. The second flow channel plate 12 also includes staggered plates, which enclose and form a second groove 120 that is not interconnected. The second connecting portion 12b1 is the end wall on the opening side of the second groove 120. The welding structure between the other side of the second flow channel plate 12 and the third flow channel plate 13 is similar to the welding connection between the first connecting portion 11b1 and the second connecting portion 12b1, and will not be described in detail here.

[0052] like Figures 2-6 As shown, the central axis of the mounting portion 11a is set at an angle of 0-180 degrees to the first surface S. Alternatively, the central axis of the valve core of the first valve 21 is set at an angle of 0-180 degrees to the first surface S. In this embodiment, the central axis of the mounting portion 11a is coaxial with the central axis of the valve core of the first valve 21. Therefore, the central axis of the mounting portion 11a described below can be considered equivalent to the central axis of the valve core of the first valve 21. In this embodiment, the central axis of the valve core of the first valve 21 is parallel to the first surface S, and the control valve is mounted on the mounting portion 11a along the first surface S. This arrangement simplifies the structure of the first flow channel plate 11, allowing the arrangement of the outlet flow channel of the eight-way valve to be achieved with a single-layer flow channel plate. Specifically, the connecting port 11a1 is located on the side of the cylindrical peripheral wall 11a2 near the first connecting portion 11b1, facilitating communication between the connecting port 11a1 and the first groove 110 of the flow channel portion 11b.

[0053] like Figures 7-11As shown, the structure of the second flow channel plate 12 is described in detail. The second flow channel plate 12 has a second connecting hole 12a, which allows the second groove 120 to communicate with the fourth groove 120'. In this embodiment, the second connecting hole 12a includes a first hole 12a1, a second hole 12a2, a third hole 12a3, a fourth hole 12a4, a fifth hole 12a5, and a sixth hole 12a6. Among them, the first hole 12a1, the third hole 12a3, the fourth hole 12a4, the fifth hole 12a5, and the sixth hole 12a6 are through holes, that is, at least a portion of the second groove 120 and at least a portion of the fourth groove 120' are arranged back to back, and at least a portion of the second groove 120 and at least a portion of the fourth groove 120' share a bottom wall. When the connecting hole is opened on the shared bottom wall, it can directly connect the grooves on both sides.

[0054] like Figure 8 As shown, the second groove 120 includes a first groove 121 and a second groove 122, which are arranged side by side along a first direction X; as Figure 11 As shown, the fourth groove 120' includes a third groove 123 and a fourth groove 124, which are arranged side by side along the second direction Y. The projections of the first groove 121 and the third groove 123 on the first surface S overlap, as do the projections of the second groove 122, the third groove 123, and the fourth groove 124 on the first surface S. The second hole 12a2 connects the first groove 121 and the third groove 123, and the third hole 12a3 connects the second groove 122 and the fourth groove 124. On one surface, the second hole 12a2 and the third hole 12a3 are arranged diagonally. The diagonally arranged connecting holes facilitate the connection between the second groove 120 and the fourth groove 120'.

[0055] Example 2:

[0056] Another embodiment of this application provides a fluid control component, such as... Figures 14-22 As shown below, the differences between the fluid control component in Embodiment 2 and the fluid control component in Embodiment 1 will be highlighted.

[0057] In this embodiment, the fluid management unit 2 includes a control valve and a pump assembly 24. The control valve includes a first valve 21, a second valve 22, and a third valve 23. The fluid management unit 2 also includes a storage device 25.

[0058] like Figure 14 and Figure 15As shown, the flow channel plate assembly 10 includes a first side portion 101 and a third side portion 103. At least a portion of the first side portion 101 and at least a portion of the third side portion 103 are arranged parallel to each other and both extend along the first surface S. Along the normal direction of the first surface S, a second valve 22 and a pump assembly 24 are mounted on the third side portion 103, and a first valve 21 and a third valve 23 are mounted on the first side portion 101. The central axis of the valve core of the first valve 21 is parallel to the normal direction of the first surface S. Of course, in other embodiments, the first valve 21, the second valve 22, the third valve 23, and the pump assembly 24 can be mounted on the same side portion of the flow channel plate assembly 10. The central axis of the first valve 21 is parallel to the normal direction of the first surface S. This arrangement makes the thickness of the flow channel plate assembly 10 in the third direction Z smaller and the structure more compact.

[0059] like Figures 16-19 As shown, the structure of the flow channel plate assembly 10 is described in detail. Figure 17 As shown, the flow channel plate assembly 10 includes a first flow channel plate 11, a second flow channel plate 12, and a third flow channel plate 13. The first flow channel plate 11, the second flow channel plate 12, and the third flow channel plate 13 are arranged along a third direction Z. The second flow channel plate 12 is located on one side of the first flow channel plate 11, and the third flow channel plate 13 is located on the opposite side of the first flow channel plate 11. In other words, the third flow channel plate 13 is located on the side of the first flow channel plate 11 away from the second flow channel plate 12. In other embodiments, the second flow channel plate 12 may be partially located on one side of the first flow channel plate 11, and the third flow channel plate 13 may be partially located on the opposite side of the first flow channel plate 11.

[0060] like Figures 17-19As shown, the first flow channel plate 11 has a first groove 110 and a third groove 110'. The first groove 110 is located on the side of the first flow channel plate 11 near the second flow channel plate 12, and the third groove 110' is located on the side of the first flow channel plate 11 near the third flow channel plate 13. The first groove 110 and the third groove 110' are located on opposite sides of the first flow channel plate 11, that is, grooves are formed by recessing inward from opposite sides of the first flow channel plate 11 along the normal direction of the first surface S. At least a portion of the second groove 120 and at least a portion of the fourth groove 120' have a common bottom wall. The first groove 110 forms at least a portion of the first flow channel 104, and the third groove 110' forms at least a portion of the second flow channel 105. In this embodiment, the second flow channel plate 12 and the third flow channel plate 13 are plates. At least a portion of the shape of the second flow channel plate 12 is consistent with the shape of the first groove 110, and at least a portion of the shape of the third flow channel plate 13 is consistent with the shape of the third groove 110'. The second flow channel plate 12 can cover the first groove 110 to form the first flow channel 104, and the third flow channel plate 13 can cover the third groove 110' to form the second flow channel 105. The wall forming the first flow channel 104 includes the wall of the first flow channel plate 11 and the wall of the second flow channel plate 12, and the wall forming the second flow channel 105 includes the wall of the first flow channel plate 11 and the wall of the third flow channel plate 13. The second flow channel plate 12 can be multiple separate plates, or it can be connected into an integral structure by connecting ribs. The third flow channel plate 13 can be arranged in a similar manner to the second flow channel plate 12. In other embodiments, the second flow channel plate 12 may also have a groove adapted to the first groove 110, and the third flow channel plate 13 may also have a groove adapted to the third groove 110', so that the grooves are joined together to form a flow channel. In this embodiment, the interface portion 14 is located in the first flow channel plate 11, the second flow channel plate 12, and the third flow channel plate 13. The first flow channel plate 11 includes an interface portion 14 protruding in the positive direction of the third direction Z, the second flow channel plate 12 includes an interface portion 14 protruding in the negative direction of the third direction Z, and the third flow channel plate 13 includes an interface portion 14 protruding in the positive direction of the third direction Z.

[0061] In this embodiment, the first flow channel plate 11 includes a mounting portion 11a, a second mounting portion 13a, and a flow channel portion 11b. The mounting portion 11a, the second mounting portion 13a, and the flow channel portion 11b are integrally structured. The mounting portion 11a has a receiving cavity 11a0. The wall forming the receiving cavity 11a0 includes the wall of the mounting portion 11a. At least a portion of the valve core of the first valve 21 is located in the receiving cavity 11a0. The second mounting portion 13a is used to mount the second valve 22, the third valve 23, or the pump assembly 24. The center lines of the mounting portion 11a and the second mounting portion 13a are both parallel to the normal of the first surface S. The central axis of the valve core of the first valve 21 is perpendicular to the first surface S. Along the normal direction of the first surface S, the first valve 21 is mounted on the mounting portion 11a. In other words, the first valve 21, the second valve 22, the third valve 23, and the pump assembly 24 are all mounted on the first flow channel plate 11 along the normal direction of the first surface S. The openings of the mounting portion 11a corresponding to the first valve 21 and the second mounting portion 13a corresponding to the third valve 23 face the negative direction of the third direction Z, while the openings of the second mounting portion 13a corresponding to the second valve 22 and the second mounting portion 13a corresponding to the pump assembly 24 face the positive direction of the third direction Z. In this embodiment, the structure of the first flow channel plate 11 is more complex than that of the second flow channel plate 12 and the third flow channel plate 13. Concentrating the complex structure in the first flow channel plate 11 reduces the manufacturing cost of the second flow channel plate 12 and the third flow channel plate 13 during the manufacturing of the flow channel plate assembly 10, thus reducing the overall manufacturing cost of the flow channel plate assembly 10.

[0062] like Figure 17 As shown, the mounting part 11a includes a cylindrical peripheral wall 11a2, which has at least two connecting ports 11a1. In this embodiment, the number of connecting ports 11a1 is eight. Along the third direction Z, the connecting ports 11a1 include a first connecting port 11a11 and a second connecting port 11a12. The first connecting port 11a11 and the second connecting port 11a12 are arranged side by side. The first connecting port 11a11 is connected to at least a portion of the first flow channel 104, and the second connecting port 11a12 is connected to at least a portion of the second flow channel 105. The two flow channels along the third direction Z can adjust their connection relationship by rotating the valve core of the first valve 21.

[0063] like Figure 17As shown, the storage device 25 includes a first housing 251 and a second housing 252, which are welded together. The first housing 251 is integrally formed with the first flow channel plate 11. The second housing 252 covers the opening of the first housing 251 to form a liquid storage chamber for the storage device 25. The storage device 25 is used to store coolant. The chamber of the storage device 25 is connected to the flow channel of the first flow channel plate 11. By providing a connection port 11a1, the storage devices 25 can be connected in series or in parallel in the flow path formed by the flow channel of the first flow channel plate 11. In addition, when the coolant in the circuit decreases after the thermal management system has been running for a period of time, it can be replenished through the storage device 25.

[0064] like Figures 20-22 As shown, the connection structure between the flow channel portion 11b and the mounting portion 11a is described in detail, specifically focusing on the partial welded connection structure between a section of the second flow channel plate 12 and the flow channel portion 11b. The first connecting portion 11b1 includes an extension portion 11c, which protrudes from the peripheral wall of the mounting portion 11a away from the receiving cavity 11a0. At least a portion of the extension portion 11c is parallel to the first surface S. The extension portion 11c can cover a portion of the first groove 110, so that the second flow channel plate 12 does not need to be welded close to the mounting portion 11a, avoiding the need for the second flow channel plate 12 to have an arc-shaped welding structure matching the mounting portion 11a, thus simplifying the structure of the second flow channel plate 12.

[0065] like Figure 20 As shown, the extension 11c includes a first inclined portion 11c1. After extending along the first surface S, the extension 11c extends inclinedly near the groove to form the first inclined portion 11c1. The first inclined portion 11c1 includes a flat inclined surface. The corresponding second flow channel plate 12 includes a second inclined portion 12c1. The second inclined portion 12c1 is welded to the first inclined portion 11c1. The second inclined portion 12c1 and the first inclined portion 11c1 are mirror-symmetrically arranged with the welding surface as the center plane. The arrangement of the first inclined portion 11c1 and the second inclined portion 12c1 facilitates accurate positioning when the second flow channel plate 12 is welded to the flow channel portion 11b.

[0066] The first connecting portion 11b1 also includes a first arc portion 11b2 and a first straight portion 11b3. One end of the first arc portion 11b2 is connected to the first inclined portion 11c1, and the other end of the first arc portion 11b2 is connected to the first straight portion 11b3. Along the direction of the recess of the first groove 110, the first inclined portion 11c1 and the first straight portion 11b3 are located at different heights. The first arc portion 11b2 allows for a smooth transition in the connection area from the first inclined portion 11c1 to the first straight portion 11b3. The corresponding second connecting portion 12b1 includes a second arc portion 12b2 and a second straight portion 12b3. Similarly, the second arc portion 12b2 is mirror-symmetrical to the first arc portion 11b2 with the welding surface as the center plane, and the second straight portion 12b3 is mirror-symmetrical to the first straight portion 11b3 with the welding surface as the center plane. The first inclined portion 11c1 is a part of the extension 11c. The first inclined portion 11c1 can cover part of the first groove 110. In other words, the first inclined portion 11c1 overlaps the two side walls of the first groove 110. That is, one first inclined portion 11c1 corresponds to two first arc-shaped portions 11b2. The arrangement of the second arc-shaped portion 12b2 makes the second connecting portion 12b1 of the second flow channel plate 12 have a smooth connecting surface, which is simple in structure and also facilitates the connection between the second flow channel plate 12 and the flow channel portion 11b. Such a connection structure can also be applied to the welding connection between the flow channel portion 11b and the third flow channel plate 13.
