[0038] Embodiment 1:

[0039] One embodiment of the present application provides a fluid control assembly, such as Figure 1-12As shown, the fluid control assembly includes a flow channel plate assembly 10 and a fluid management unit 20, the fluid management unit 20 is fixedly connected or limitedly connected to the flow channel plate assembly 10, the fluid management unit 20 has a channel for circulating medium or a cavity for storing circulating medium, and the channel or cavity of the fluid management unit 20 is connected to the flow channel of the flow channel plate assembly 10. The fluid management unit 20 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, at least part of the valve core is located in the accommodating cavity 11a0 of the flow channel plate assembly or the mounting cavity of the second mounting portion 13a. In this embodiment, the first valve 21 is an eight-way water valve, and the specific eight-way water valve is 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, and other multi-way water valves with other numbers of channels. In this embodiment, the second valve 22 is a three-way water valve, and the number of the second valves 22 is two. In other embodiments, the second valve 22 can also be replaced by a multi-way water valve with other numbers of channels. In this embodiment, the third valve 23 is a one-way valve, and the number of the third valves 23 is two. The third valves 23 are installed on the side of the flow channel plate assembly 10. In other embodiments, the third valve 23 can be installed in the flow channel of the flow channel plate assembly 10. In this embodiment, the number of the pump assemblies 24 is three, and 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 other sides of the flow channel plate assembly 10, or installed on the other side opposite to the flow channel plate assembly 10. The present 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 set as needed, and at least one of the first valve 21, the second valve 22, the third valve 23, and the pump assembly 24 can also be included.

[0040] like Figure 1 As shown, the first direction X, the second direction Y and the third direction Z are defined. The first direction X, the second direction Y and the third direction Z are perpendicular to each other. The second direction Y is set as the vertical direction, and the first direction X and the third direction Z are two directions of the horizontal plane. The direction marked with an arrow is designated as the positive direction, and the other direction is designated as the negative direction. For example, in this embodiment, the negative direction of the second direction Y is the gravity direction. The surface formed by the first direction X and the second direction Y is defined as the first surface S, and the third direction Z is the normal direction of the first surface S. In this embodiment, the flow channel assembly 10 extends along the first surface S, and the flow channel assembly 10 has a flow channel, which includes a first flow channel 104 and a second flow channel 105. The flow channel of the flow channel assembly 10 also extends along the first surface S. In other words, the flow channel assembly 10 has a certain thickness in the third direction Z, and the groove forming the flow channel is recessed from the side wall of the flow channel assembly 10 along the third direction Z. The first surface S is also a surface parallel to the extension direction of the first flow channel 104.

[0041] like Figure 1 As shown, different fluid management units 20 are installed on different sides of the flow channel plate assembly 10. The flow channel plate assembly 10 includes a first side portion 101 and a second side portion 102, the first side portion 101 and the second side portion 102 are arranged at an angle, specifically, the first side portion 101 and the second side portion 102 are arranged at an angle of 90 degrees, at least part of the first side portion 101 extends along the first surface S, along the normal direction of the first surface S, the second valve 22, the third valve 23, and the pump assembly 24 are installed on the first side portion 101, the first valve 21 is installed on the second side portion 102, and the center axis of the valve core of the first valve 21 is parallel to the first surface S. In this arrangement, the length and width of the fluid control assembly can be significantly reduced while appropriately increasing the thickness of the fluid control assembly, so that the fluid control assembly has a compact structure, which is conducive to the miniaturization of the fluid control assembly. The second valve 22, the third valve 23 and the pump assembly 24 are installed on the first side portion 101, that is, installed on the same side of the flow channel plate assembly 10, which 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, it is only necessary to reserve installation space on the first side portion 101 of the flow channel plate assembly 10.

[0042] Specifically, along the gravity direction, 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, at least one of which is used to inject coolant into the fluid control assembly. That is to say, along the gravity direction, the pump assembly 24 is arranged below the injection interface, which is conducive to the removal of residual air in the pump cavity and improves 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 linearly arranged along the first direction X.

[0043] Along the direction of gravity, the second valve 22 and the third valve 23 are installed above the pump assembly 24. The second valve 22 and the third valve 23 are arranged at the same height. When the second valve 22, the third valve 23, and the pump assembly 24 are installed on the same first side portion 101, this arrangement is conducive to the miniaturized design 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 are arranged on the first side portion 101, and the other pump is arranged on the opposite side of the first side portion 101, or one pump is arranged on the second side portion 102, and the installation height of the pump is lower than the height of the first valve 21 to meet the exhaust requirements when the pump is installed.

[0044] The fluid control assembly is applied to a thermal management system. The fluid control assembly includes an interface 140 connected to other devices of 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, and the interface member 140 is welded to the interface portion 14. Other devices are directly fixedly connected or limitedly connected to the interface member 140 through pipelines. The setting of the interface member 140 facilitates the connection of other devices in the thermal management system with the fluid control assembly. In other embodiments, the interface portion 14 can also be integrally formed with the interface member 140. In this embodiment, as shown in FIG. Figure 2 and Figure 4 As shown, the interface portion 14 is located at the first flow channel plate 11 and the third flow channel plate 13, the first flow channel plate 11 includes an interface portion 14 formed by protruding along the negative direction of the third direction Z, the third flow channel plate 13 includes an interface portion 14 formed by protruding along the positive direction of the third direction Z, and the third flow channel plate 13 also includes other interface portions 14 formed by protruding along the positive direction of the second direction Y. Of course, in other embodiments, the interface portion 14 may also be located at the second flow channel plate 12.

[0045] like Figure 2-13 As shown in FIG. 1 , the structure of the flow channel plate assembly 10 is described in detail. Figure 2-Figure 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 the 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 other 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 can also be located on one side of the second flow channel plate 12, and part of the third flow channel plate 13 can be located on the other side of the second flow channel plate 12. The first flow channel plate 11 and the second flow channel plate 12 are welded and connected, and the second flow channel plate 12 and the third flow channel plate 13 are welded and connected. The three-layer flow channel plate is stacked, and the flow channel plate assembly 10 can be compact in structure and occupy a small space while meeting the flow channel connection requirements of the flow channel plate. In other embodiments, the second flow channel plate 12 may also be an integral structure with at least one of the first flow channel plate 11 and the third flow channel plate 13 .

[0046] like Figure 3-Figure 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 one side close to the second flow channel plate 12, and the first groove 110 is recessed from the side wall 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 one side close to the first flow channel plate 11, and the second flow channel plate 12 has a fourth groove 120' on one side close to 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, the grooves are recessed inwardly along the normal direction of the first surface S from the opposite sides of the second flow channel plate 12, at least part of the grooves. 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 a side close to the second flow channel plate 12, and 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 portion 13a on a side away from the second flow channel plate 12, and the second mounting portion 13a is used to install the second valve 22, the third valve 23 or the pump assembly 24. The center line of the second mounting portion 13a is parallel to the normal line of the first surface S, and the opening of the second mounting portion 13a faces the positive direction of the third direction Z.

[0047] The flow channel plate assembly 10 has a flow channel, and along the third direction Z, the flow channel includes a first flow channel 104 and a second flow channel 105. The first flow channel plate 11 and the second flow channel plate 12 are welded and connected, and 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, the first groove 110 forms at least part of the first flow channel 104, and the second groove 120 forms at least part of the first flow channel 104; the second flow channel plate 12 and the third flow channel plate 13 are welded and connected, and the wall forming the second flow channel 105 includes the wall of the second flow channel plate 12 and the wall of the third flow channel plate 13, the fourth groove 120' forms at least part of the second flow channel 105, and the fifth groove 130 forms at least part of the second flow channel 105. Specifically, the opening of the first groove 110 is arranged opposite to the opening of the second groove 120, and the opening of the fourth groove 120' and the opening of the fifth groove 130 are arranged opposite to each other, and the welding connection can form at least part of the flow channel after the grooves are butt-welded. In other embodiments, one side may be a groove and the other side may be a flat plate structure, and then the flat plate structure covers the opening of the groove to form a partial flow channel, and the flat plate may be located in 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 a flat plate structure covers the first groove 110 to form the first flow channel 104, and the first flow channel 104 can be connected to the second flow channel 105 through the opening on the flat plate, or through the opening on the flow channel portion 11b and the opening of the interface portion 14 formed on the flow channel portion 11b. In this embodiment, the second flow channel plate 12 has a first hole 12a1, and the first hole 12a1 is a through hole. The opening of a groove in the first groove 110 is arranged opposite to the first hole 12a1, and 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, and the mounting portion 11a and the flow channel portion 11b are an integral structure. 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 part 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, which has at least two communication ports 11a1. The first flow channel plate 11 has at least two first channels 1041. The first channel 1041 is a part of the first flow channel 104. The first channel 1041 has a communication port 11a1 on the wall of the mounting portion 11a. In this embodiment, the number of the communication ports 11a1 is eight. Correspondingly, the first groove 110 includes eight grooves that are not connected to each other in the first flow channel plate 11. The communication ports 11a1 correspond to the first grooves 110 one by one, and then the accommodating chamber 11a0 is connected to the first groove 110. By rotating the valve core of the first valve 21, the medium flowing into the accommodating chamber 11a0 can be adjusted to flow out through different communication ports 11a1. That is, rotating the valve core of the first valve 21 can make different first flow channels 104 connected. In other embodiments, the mounting portion 11a can also be used to install the pump assembly 24.

[0049] The flow channel portion 11b includes plates arranged in a staggered manner, and the flow channel portion 11b has a first groove 110. The plates arranged in a staggered manner enclose and form mutually unconnected first grooves 110. The first grooves 110 form at least part of the first flow channel 104, and at least part of the flow channel portion 11b extends along the first surface S. It should be noted here that the first flow channel 104 includes a first channel 1041 and an extended flow channel 1042. Compared with the valve housing of a general water valve column valve, the valve housing includes a receiving portion and a connecting portion. The receiving portion is used to install the valve core, and the connecting portion is used to install and connect with the flow channel plate. The connecting portion has a receiving cavity connecting the receiving portion and a channel of 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 the general water valve column valve, and the extended flow channel 1042 refers to the first flow channel 104 of the general channel extending along the first surface S. In this embodiment, a part of the first grooves 110 forms the first channel 1041, and another part of the first grooves 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 to form the flow channel, so that the first flow channel plate 11 installed with the first valve 21 has diversified functions. Part of the flow channel portion 11b includes an interface portion 14 on the side away from the first groove 110, so that the first flow channel 104 located in the flow channel portion 11b can be connected to other devices in the thermal management system through the interface portion 14.

[0050] The flow channel portion 11b includes a first connection portion 11b1, the first channel 1041 has an opening in the first connection portion 11b1, the second flow channel plate 12 includes a second connection portion 12b1, the connection port of the second connection portion 12b1 is communicated with the first channel 1041, the first connection portion 11b1 and the second connection portion 12b1 are welded and connected, compared with the general water valve and the flow channel plate bolt connection, in this embodiment, the first flow channel plate 11 with the first valve 21 installed is welded and connected to the second flow channel plate 12, specifically, the first connection portion 11b1 and the second connection portion 12b1 are welded and connected, which can save the setting of the sealing ring at the connection position and save the installation process of the bolt connection, which is beneficial to reduce the manufacturing cost of the fluid control component.

[0051] The first connection portion 11b1 is the end wall of the opening side of the first groove 110, and is 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 a second groove 120 that is not connected to each other. The second connection portion 12b1 is the end wall of the opening side of the second groove 120. The welding structure of the other side of the second flow channel plate 12 and the third flow channel plate 13 is similar to the welding connection of the first connection portion 11b1 and the second connection portion 12b1, and will not be repeated here.

[0052] like Figure 2-Figure 6 As shown, the central axis of the mounting portion 11a is set at an angle of 0-180 degrees with the first surface S. In other words, the central axis of the valve core of the first valve 21 is set at an angle of 0-180 degrees with 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, so the central axis of the mounting portion 11a described below can be 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 installed on the mounting portion 11a along the first surface S. This arrangement makes the structure of the first flow channel plate 11 simple, and a single-layer flow channel plate can realize the arrangement of the outlet flow channel of the eight-way valve. Specifically, the communication port 11a1 is arranged on the side of the cylindrical peripheral wall 11a2 close to the first connecting portion 11b1, so that the communication port 11a1 is connected to the first groove 110 of the flow channel portion 11b.

[0053] like Figure 7-Figure 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. The second connecting hole 12a can make the second groove 120 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 straight holes, that is, at least part of the second groove 120 and at least part of the fourth groove 120' are arranged back to back, and at least part of the second groove 120 and at least part of the fourth groove 120' share a bottom wall. When the connecting hole is opened on the shared bottom wall, the grooves on both sides can be directly connected.

[0054] like Figure 8 As shown, the second groove 120 includes a first groove 121 and a second groove 122, and the first groove 121 and the second groove 122 are arranged in parallel along the first direction X; Fig.11 As shown, the fourth groove 120' includes a third groove 123 and a fourth groove 124, and the third groove 123 and the fourth groove 124 are arranged in parallel along the second direction Y; the projections of the first groove 121 and the third groove 123 on the first surface S overlap, and the projections of the second groove 122, the third groove 123 and the fourth groove 124 on the first surface S overlap, and 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'.

The center lines of the mounting portion 11a and the second mounting portion 13a are parallel to the normal of the first surface S. The center 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 installed 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 installed on the first flow channel plate 11 along the normal direction of the first surface S, wherein the opening of the mounting portion 11a corresponding to the first valve 21 and the opening of the second mounting portion 13a corresponding to the third valve 23 face the negative direction of the third direction Z, and the opening of the second mounting portion 13a corresponding to the second valve 22 and the opening of 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. The complex structure is concentrated on the first flow channel plate 11. When manufacturing the flow channel plate assembly 10, the manufacturing cost of the second flow channel plate 12 and the third flow channel plate 13 can be reduced, which is generally beneficial to reducing the manufacturing cost of the flow channel plate assembly 10.

[0062] like Fig.17 As shown, the mounting portion 11a includes a cylindrical circumferential wall 11a2, and the cylindrical circumferential wall 11a2 has at least two communicating ports 11a1. In the present embodiment, the number of the communicating ports 11a1 is eight. Along the third direction Z, the communicating ports 11a1 include a first communicating port 11a11 and a second communicating port 11a12.

[0063] like Fig.17As shown, the storage device 25 includes a first shell 251 and a second shell 252, the first shell 251 and the second shell 252 are welded and connected, the first shell 251 and the first flow channel plate 11 are integrally structured, the second shell 252 covers the opening of the first shell 251 to form a liquid storage cavity of the storage device 25, the storage device 25 is used to store coolant, the cavity of the storage device 25 is connected to the flow channel of the first flow channel plate 11, and by setting the connecting port 11a1, the storage device 25 can be set 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 thermal management system runs for a period of time and the coolant in the circuit is reduced, the storage device 25 can be used for replenishment.

[0064] like Figure 20-Figure 22 As shown, the connection structure between the flow channel portion 11b and the mounting portion 11a is described in detail, and the partial welding connection structure between a sub-plate of the second flow channel plate 12 and the flow channel portion 11b is specifically introduced. The first connection portion 11b1 includes an extension portion 11c, and the extension portion 11c protrudes from the peripheral wall of the mounting portion 11a away from the accommodating cavity 11a0, and at least part of the extension portion 11c is parallel to the first surface S. The extension portion 11c can cover part 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 be provided with an arc-shaped welding structure matching the mounting portion 11a, and simplifying the structure of the second flow channel plate 12.

[0065] like Fig. 20 As shown, the extension portion 11c includes a first inclined portion 11c1. After the extension portion 11c extends along the first surface S, it extends obliquely close to 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 is mirror-symmetrically arranged with the first inclined portion 11c1 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 further 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 first groove 110, the first inclined portion 11c1 and the first straight portion 11b3 are located at different heights, and the first arc portion 11b2 enables a smooth transition from the connecting area of ​​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 and the first arc portion 11b2 are mirror-symmetrical with the welding surface as the center plane, and the second straight portion 12b3 and the first straight portion 11b3 are mirror-symmetrical with the welding surface as the center plane. The first inclined portion 11c1 is a part of the extension portion 11c, and 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 portions 11b2. The arrangement of the second arc portion 12b2 enables the second connecting portion 12b1 of the second flow channel plate 12 to have a smooth connecting surface, a simple 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.
