[0052] Fluid control components can be applied to thermal management systems, such as vehicle thermal management systems, including those for new energy vehicles. However, the application areas of the fluid control components in this embodiment are not limited to those described herein; they can also be used in other fields, such as residential air conditioning and energy storage systems.

[0053] The present application will be further described below with reference to the accompanying drawings and specific embodiments:

[0054] Example 1:

[0055] like Figures 1-17 As shown, this embodiment provides a fluid control assembly, including a first module 1 and a second module 2. The first module 1 includes a control module X, which includes a connector 10, a control component 13, and a control box 12. The connector 10 has a flow channel and a mounting cavity. The control component 13 is mounted on the connector 10. The control component 13 includes a switching component 1301 and a throttling component 1302. The switching component 1301 can connect or disconnect the flow channel connected to the mounting cavity corresponding to the switching component 1301. The throttling component 1302 can throttle the flow channel connected to the mounting cavity corresponding to the switching component 1301. The corresponding mounting cavity is connected to the flow channel. The control box 12 integrates the drive component of the control component 13. Each drive component is electrically connected to the circuit board. The openings of multiple mounting cavities of the connector 10 face the same direction. The multiple mounting cavities are arranged in an alternating manner, making full use of the space around the circular mounting cavity. This makes the connector 10 structure compact. At least some of the control components 13 are located in the mounting cavity, and at least some of the control components 13 are located in the cavity of the drive component. The control box 12 can uniformly control the action of the control components 13. The integration of the drive components makes the drive components easy to install and the structure simple.

[0056] The first module 1 includes a heat exchange device 14, a liquid storage device 15, and a connecting component 16. The connecting channel of the connecting component 16 allows the liquid storage chamber of the liquid storage device 15, the heat exchange channel of the heat exchange device 14, and the flow channel of the connector 10 to be interconnected. The second module 2 includes a support base 26, which is made of plastic. The flow section 261 of the support base 26 has a coolant flow channel 260 inside. Two pump components 21 and one coolant valve component 22 are installed on the support base 26. The pump components 21 can provide power to the coolant in the coolant flow channel 260, and the coolant valve component 22 can adjust the connection relationship between different coolant flow channels 260. In other embodiments, the pump components 21 and the coolant valve component 22 can be electrically connected to the circuit board in the control box 12 to realize the control of the control component 13, the pump components 21, and the coolant valve component 22 by a control module X. The carrier substrate 26 has a coolant interface, and the coolant flow channel 260 communicates with the opening of the coolant interface. The coolant interface is connected to other components of the thermal management system. The medium in the coolant flow channel 260 can flow through the opening to the components that require thermal management. The components that require thermal management include two or more of the following: electric drive, battery or battery cooler, radiator, and heater core. In this embodiment, the heat exchange device 14 of the first module 1 can perform thermal management on the battery. The third heat exchange channel 1403 of the heat exchange device 14 can circulate coolant and is communicated with the coolant flow channel 260.

[0057] like Figure 3 As shown, the supporting base 26 includes a mounting part 263, which and the flow part 261 are integral structures. The mounting part 263 includes a hollow bracket and a clamp that match the external dimensions of the liquid storage device 15. In this embodiment, the liquid storage device 15 is a cylindrical structure, and the hollow bracket is a corresponding semi-cylindrical groove. The clamp is bolted to the hollow bracket to fasten the liquid storage device 15 to the mounting part 263. The supporting base 26 includes a fixing part 262. The connecting member 10 and the heat exchange device 14 each include a mating part 17, which is mated to the fixing part 262. The fixing part 262 corresponds one-to-one with the mating part 17 and the fixing part 262, and is fixedly connected. Specifically, the fixing part 262 and the mating part 17 are detachably bolted together. One of the fixing part 262 and the mating part 17 is a through hole structure, and the other is internally threaded. The heat exchange device 14 and the connector 10 can be fixed to the support base 26 by fasteners. In one specific embodiment, the mating part 17 of the connector 10 and the mating part 17 of the heat exchange device 14 are both threaded blind holes, and the fixing part 262 of the support base 26 is a through hole structure. In other embodiments, the fixing part 262 can be fitted with a threaded insert for threaded connection with the fastener.

[0058] like Figures 1-4As shown, at least a portion of the supporting substrate 26, or the flow section 261, extends in a plate-like shape. The extension direction of the flow section 261 is consistent with the extension direction of the plates of the heat exchange device 14. The control component X, the heat exchange device 14, and the liquid storage device 15 are located on the same side of the supporting substrate 26 and are fixedly connected to the supporting substrate 26. The control component X, the heat exchange device 14, and the liquid storage device 15 are arranged along the extension surface of the supporting substrate 26. A first direction H is defined. The control component X and the heat exchange device 14 are arranged along the first direction H. The axial direction of the liquid storage device 15 is parallel to the first direction H. Along the radial direction of the liquid storage device 15, at least a portion of the control component X and the heat exchange device 14 are located on the same side of the liquid storage device 15. In this embodiment, the control component X and the heat exchange device 14 are located on the same side of the liquid storage device 15. In other embodiments, along the axial direction of the liquid storage device 15, a portion of the control component X is located on one side of the liquid storage device 15. A first surface S is defined. The first surface S is perpendicular to the first direction H, as shown below. Figure 4 As shown, the projections of the connecting component 16 and the flow portion 261 on the first surface S at least partially overlap. The staggered arrangement of the connecting component 16 and the flow portion 261 results in a smaller thickness of the fluid control component in the stacking direction of the heat exchange device 14, which is beneficial for the miniaturization of the fluid control component. In other embodiments, the connecting component 16 can also be a flow channel plate assembly, and both the control component X and the heat exchange device 14 are fixedly connected or limited to the flow channel plate assembly. The projections of the flow channel plate assembly and the flow portion 261 on the first surface at least partially overlap. In other embodiments, either the control module X or the heat exchange device 14 can at least partially overlap with the projection of the flow portion 261 on the first surface S, thereby reducing the thickness dimension of the support substrate on which the control module X or the heat exchange device 14 is mounted.

[0059] Specifically, the projection of the connector 10 onto the heat exchange device 14 on the first surface S at least partially overlaps, and / or, the projection of the control box 12 onto the heat exchange device 14 on the first surface S at least partially overlaps. In this embodiment, as... Figure 4 As shown, a portion of the first connector 101 and a portion of the second connector 102 overlap with the projection of the heat exchange device 14 onto the first surface S, and a portion of the control box 12 overlaps with the projection of the heat exchange device 14 onto the first surface S. In other embodiments, one of the first connector 101 and the second connector 102 may at least partially overlap with the projection of the heat exchange device 14 onto the first surface S. The fact that at least one of the connector 10 and the control box 12 at least partially overlaps with the projection of the heat exchange device 14 onto the first surface S, and that the space-consuming connector 10 and / or control box 12 are arranged around the heat exchange device 14, is beneficial for improving the space utilization of the fluid control components. Furthermore, in this embodiment, as... Figure 7As shown, the multiple mounting cavity openings of the connector 10 face the same direction. The axial direction of the control component 13 is parallel to the stacking direction of the plates of the heat exchange device 14. The control box 12 and the connector 10 are arranged along the axial direction of the control component 13. A portion of the control component 13 is mounted in the mounting cavity of the connector 10 from the same direction, and another portion is located in the cavity of the control box 12, so as to achieve unified control of the control component 13 by the control box 12. In other embodiments, the thickness of the heat exchange device 14 is equal to the overall thickness of the control component X, and the length of the heat exchange device 14 is the same as the length of the control component X. That is, the projections of the control component X and the heat exchange device 14 on the first surface S completely overlap.

[0060] In addition, in this embodiment, the connecting component 16 and the connector 10 are set separately. The connecting component 16 adopts a connecting pipe structure, and the connector 10 is used to install the control component 13. Compared with the flow channel plate structure with control components installed in the prior art, this design structure is simple and easy to process. In addition, the connecting pipe structure makes the fluid control component lighter and the connecting pipe is easy to bend, which makes the arrangement of the connector 10, heat exchange device 14 and liquid storage device 15 more flexible. The connection relationship between the connector 10, heat exchange device 14 and liquid storage device 15 can be achieved by appropriately adjusting the length or bending angle of the connecting pipe.

[0061] In one specific embodiment, the stacking direction of the heat exchanger 14 is horizontal, and the axial direction of the liquid storage device 15 is parallel to the direction of gravity. Along the axial direction of the liquid storage device 15, the control component X is located above the heat exchanger 14, or in other words, the connector 10 is located above the heat exchanger 14. This arrangement facilitates the outflow of refrigerant in the connector 10, thereby reducing the risk of blockage of the control component 13 installed on the connector 10. Along the radial direction of the liquid storage device 15, the first connector 101 and the second connector 102 are arranged side by side. The second connector 102 is arranged closer to the liquid storage device 15 than the first connector 101, making the connecting component 16 connecting the liquid storage device 15 and the second connector 102 shorter. This facilitates the flow of refrigerant in the liquid storage device 15 through the shorter connecting component 16 to the throttling component 1302. In other embodiments, the stacking direction of the heat exchanger 14 is parallel to the direction of gravity, and the axial direction of the liquid storage device 15 is also parallel to the direction of gravity. In other words, the axis of the liquid storage device 15 is perpendicular to the stacking direction of the plates of the heat exchange device 14, or the axis of the liquid storage device 15 is parallel to the stacking direction of the plates of the heat exchange device 14. This allows the fluid control assembly to be adapted to different layout spaces.

[0062] The support base 26 includes a coolant tank 264, the cavity of which communicates with the coolant flow channel 260. The coolant tank 264 is used to store coolant and also to replenish the second module 2. The flow section 261 and the coolant tank 264 of the support base 26 are an integral structure, saving the step of separately installing the coolant tank 264. In a specific embodiment, the support base 26 includes a main board and a cover plate. The cover plate is welded to the main board. The flow channel groove and the liquid storage groove are located on at least one of the main board and the cover plate. A portion of the cover plate and the corresponding main board are assembled to form the flow section 261, and another portion of the cover plate and the corresponding main board are assembled to form the coolant tank 264. The mounting part 263 and the flow section 261 are an integral structure, or they can be formed by welding two side plates together.

[0063] like Figure 1-2 As shown, in this embodiment, the control module X, heat exchange device 14, and liquid storage device 15 of the first module 1, and the pump component 21 and coolant valve component 22 of the second module 2 are arranged on the same side of the supporting base 26. The heat exchange device 14 is arranged in the center position, and other components are arranged around the heat exchange device 14. The structure is compact. Along the direction of gravity, the control module X and the heat exchange device 14 are arranged along the first direction H, and the heat exchange device 14 and the liquid storage device 15 are arranged perpendicular to the first direction H. This makes the control module X, the heat exchange device 14 and the liquid storage device 15 arranged in the same plane, thus satisfying that the pump component 21 and the coolant valve component 22 are also arranged in the same plane. The length of the control module X is shorter than the length of the support base 26. The control module X is positioned relatively in the middle of the length direction of the support base 26, resulting in empty space at both ends of the support base 26, or in other words, there is empty space above the coolant valve component 22 and the liquid storage device 15. In this embodiment, at least a portion of the coolant tank 264 is arranged on both sides of the connector 10 along its length direction, thereby improving the space utilization of the fluid control component. Specifically, perpendicular to the first direction H, the coolant tank 264 is located on the periphery of the connector 10. Specifically, the connector 10 is roughly rectangular, and its periphery includes four sides. One side is equipped with the control box 12, and the other three sides are each equipped with a portion of the coolant tank 264. Some components of the first module 1 and components of the second module 2 are arranged on the same side of the support base 26, which facilitates the management of the components of the fluid control component and makes the opposite side of the support base 26 relatively flat, facilitating the installation of the fluid control component.

[0064] like Figures 1-3As shown, the support substrate 26 includes a barrier portion Z. At least a portion of the first connector 101 is located on one side of the barrier portion Z, and at least a portion of the second connector 102 is located on the opposite side of the barrier portion Z. The thermal conductivity of the material of the barrier portion Z is lower than that of the material of the first connector 101, which effectively reduces heat transfer compared to the integral structure of the connector 10. Generally, the material of the connector 10 is aluminum. In this embodiment, the barrier portion Z is integrally structured with the support substrate 26, and the material of the barrier portion Z is also plastic. Plastic has a lower thermal conductivity than aluminum. In a specific embodiment, the cavity of the barrier portion Z stores a medium, such as coolant. The thermal conductivity of this medium is lower than that of the material of the first connector 101, which also helps to reduce harmful heat transfer. In this embodiment, the cavity of the barrier portion Z is connected to the cavity of the coolant tank 264, and then to the coolant flow channel 260.

[0065] Specifically, such as Figure 6 and Figure 8 As shown, the heat exchanger 14 includes a first heat exchange channel 1401, a second heat exchange channel 1402, and a third heat exchange channel 1403. The first heat exchange channel 1401 is through which high-temperature refrigerant flows in from the liquid storage chamber. The second heat exchange channel 1402 is through which low-temperature refrigerant flows in from the first low-temperature flow channel L1 of the connector 10. The third heat exchange channel 1403 is through which coolant, such as water, flows. In this embodiment, the medium in the first heat exchange channel 1401 can exchange heat with a portion of the medium in the second heat exchange channel 1402. In addition, the medium in the second heat exchange channel 1402 can exchange heat with the medium in the third heat exchange channel 1403.

[0066] The heat exchange device 14 is a plate heat exchanger. The heat exchange interface 141 of the heat exchange device 14 includes a first heat exchange interface 1411, a second heat exchange interface 1412, a third heat exchange interface 1413, a fourth heat exchange interface 1414, and an external heat exchange interface 1415. The external heat exchange interface 1415 is located on the side of the heat exchange device 14 away from the connecting component 16. The external heat exchange interface 1415 is used to connect to the thermal management components other than the fluid control components. In this embodiment, it is connected to the interface of the third heat exchanger in the thermal management system. The other four heat exchange interfaces 141 are located on the side of the heat exchange device 14 closer to the connecting component 16, which facilitates connection to the connecting component 16. One end of the first heat exchange channel 1401 is connected to the opening of the first heat exchange interface 1411, and the other end is connected to the opening of the second heat exchange interface 1412. One end of the second heat exchange channel 1402 is connected to the opening of the third heat exchange interface 1413, and the other end is connected to the opening of the fourth heat exchange interface 1414. The opening of the external heat exchange interface 1415 is connected to the second heat exchange channel 1402 from the other side. The heat exchange device 14 includes a coolant inlet and a coolant outlet. The two ends of the third heat exchange channel 1403 are connected to the openings of the coolant inlet and the coolant outlet, respectively. The heat exchange device 14 serves as an evaporator and integrates the intermediate heat exchange function for high-temperature and low-temperature refrigerants, reducing the need for separate intermediate heat exchangers and making the fluid control assembly structure more compact.

[0067] like Figure 4 and Figure 5 As shown, the liquid storage device 15 has a liquid storage chamber that can communicate with the heat exchange channel or the flow channel of the connector 10. The liquid storage device 15 includes a head and a cylinder. In this embodiment, the head of the liquid storage device 15 is located below the cylinder, and the liquid storage device 15 has an inverted structure. The head covers the opening of the cylinder to form the liquid storage chamber, and the head is provided with a liquid storage interface portion 51, specifically including a first opening portion 511, a second opening portion 512, a third opening portion 514, and an outlet portion 513. Figure 17As shown, the end cap has a first inlet channel and a second inlet channel. One end of the first inlet channel is connected to the opening of the first opening 511, and the other end is connected to the liquid storage chamber. One end of the second inlet channel is connected to the opening of the second opening 512, and the other end is connected to the liquid storage chamber. The liquid storage device 15 includes two one-way components, respectively disposed in the first inlet channel and the second inlet channel. The one-way components allow the medium to flow into the liquid storage chamber only from the opening of the first inlet or the opening of the second inlet, and prohibit the medium in the liquid storage chamber from flowing out from the opening of the first inlet or the opening of the second inlet. The end cap is provided with an outlet channel, one end of which is connected to the liquid storage chamber, and the other end is connected to the opening of the outlet 513, allowing the liquid refrigerant in the liquid storage chamber to flow out through the opening of the outlet 513. The end cap also has a bypass channel. One end of the bypass channel is connected to the opening of the third opening 514, and the other end is connected to the end of the second inlet channel near the second opening 512, and then to the opening of the second opening 512. In one working mode, the bypass channel is connected to the first cryogenic flow channel L1 of the second connector 102. Cryogenic refrigerant flows through the bypass channel. Cryogenic refrigerant also flows in the part of the second inlet channel connected to the bypass channel. High-pressure refrigerant is stored in the liquid storage chamber. The one-way component can cut off the flow of refrigerant from the second inlet channel to the liquid storage chamber through the one-way component when there is a pressure difference. The outlet 513 and the third opening 514 are both located on the side of the end cap near the connecting component 16, and the first opening 511 and the second opening 512 are located on the opposite side of the end cap, which facilitates the connection of the outlet 513 and the third opening 514 to the connecting component 16. The first opening 511 connects to the second heat exchanger in the thermal management system where the fluid control component is located, and the second opening 512 connects to the first heat exchanger in the same system. Alternatively, the first and second openings 511 and 512 can be considered external interfaces for the fluid control component. These external interfaces are located away from the connecting component 16 for ease of installation. The first inlet channel, second inlet channel, outlet channel, and bypass channel are formed by machining, simplifying the manufacturing process. The thermal management system adjusts different operating modes through the control component 13. The valve component 13 is integrated onto the connector 10. The arrangement of the flow channels on the connector 10 is relatively complex. In this embodiment, the bypass channel simplifies the arrangement of the flow channels on the connector 10, resulting in a simpler structure.

[0068] like Figures 12-16As shown, the flow channels of the connector 10 include a first flow channel 1001, a second flow channel 1003, a third flow channel 1002, and a fourth flow channel 1004. The first mounting cavity 1011 and the third mounting cavity 1012 are both connected to the first flow channel 1001. The first flow channel 1001 includes a first sub-flow channel 1001a, a second sub-flow channel 1001b, and a third sub-flow channel 1001c. The first sub-flow channel 1001a is connected to both the first mounting cavity 1011 and the third mounting cavity 1012. The second sub-flow channel 1001b is connected to the first mounting cavity 1011. The first valve component 131 can connect or disconnect the first sub-flow channel 1001a and the second sub-flow channel 1001b. The third sub-flow channel 1001c is connected to the third mounting cavity 1012. The third valve component 132 can connect or disconnect the first sub-flow channel 1001a and the third sub-flow channel 1001c. The second mounting cavity 1021 is connected to the third flow channel 1004. The third flow channel 1002 is connected to the second mounting cavity 1021. The third valve component 133 can connect or disconnect the fourth sub-flow channel 1002a and the fifth sub-flow channel 1002b. The first throttling mounting cavity 1022 is connected to the second flow channel 1003. The second flow channel 1003 includes a sixth sub-flow channel. The sixth sub-flow channel 1003a and the seventh sub-flow channel 1003b are connected by a first throttling component 134, which can throttle the connection between the sixth sub-flow channel 1003a and the seventh sub-flow channel 1003b. The second throttling mounting cavity 1023 is connected to the fourth flow channel 1004, which includes an eighth sub-flow channel 1004a and a ninth sub-flow channel 1004b. The second throttling component 135 can throttle the connection between the eighth sub-flow channel 1004a and the ninth sub-flow channel 1004b. Figure 7 and Figure 9 As shown, the connector 10 also includes a sensor mounting cavity T0, at least a portion of which is located in the sensor mounting cavity T0. The sensor mounting cavity T0 is connected to the fifth sub-channel 1002b. The sensor T can detect the temperature and / or pressure of the medium flowing in the fifth sub-channel 1002b. The sensor T is electrically connected to the circuit board of the control box 12. The circuit board can collect the parameters of the sensor T. In this embodiment, the sensor mounting cavity T0 and the mounting cavity corresponding to the control component 13 are located on the same side of the connector 10 and have the same opening direction, which facilitates the common electrical connection of a control box 12, control component 13 and sensor T.

[0069] In the prior art, the flow channel plate assembly has a connecting flow channel, and the valve component is directly installed on the flow channel plate assembly. The valve component controls the connection relationship of the flow channel in the flow channel plate assembly to achieve different working modes. The arrangement of the flow channel is relatively complex. The flow channel plate assembly is processed by die casting or forging, and the overall weight is large. Harmful heat transfer can be reduced by setting heat insulation grooves between the high and low temperature flow channels on the flow channel plate assembly, or by arranging the high temperature valve component and the low temperature valve component in separate areas. However, in the prior art, the flow channel plate assembly as a whole still has harmful heat transfer.

[0070] In this embodiment, the flow channels of the connector 10 include a high-temperature flow channel G and a low-temperature flow channel L. The high-temperature flow channel G includes a first high-temperature flow channel G1 and a second high-temperature flow channel G2. The low-temperature flow channel L includes a first low-temperature flow channel L1 and a second low-temperature flow channel L2. In this application, the first high-temperature flow channel G1 is defined as a portion of the flow channel of the connector 10 connecting the outlet of the compressor and the inlet of the condenser. The second high-temperature flow channel G2 is defined as a portion of the flow channel of the connector 10 connecting the outlet of the condenser to the inlet of the throttling component 1302. The first low-temperature flow channel L1 is defined as a portion of the flow channel of the connector 10 connecting the outlet of the throttling component 1302 to the inlet of the evaporator. The second low-temperature flow channel L2 is defined as a portion of the flow channel of the connector 10 connecting the outlet of the evaporator to the inlet of the compressor.

[0071] like Figures 9-11 As shown, the connector 10 includes a first connector 101 and a second connector 102. The first connector 101 and the second connector 102 are separate and spaced apart. A first flow channel 1001 is located on the first connector 101. A third flow channel 1002, a second flow channel 1003, and a fourth flow channel 1004 are located on the second connector 102. The third flow channel 1002, the second flow channel 1003, and the fourth flow channel 1004 are arranged at intervals along the arrangement direction of the first connector 101 and the second connector 102. The third flow channel 1002 is closer to the first connector 101 than the second flow channel 1003 or the fourth flow channel 1004. At least a portion of the first flow channel 1001 is a first high-temperature flow channel G1, at least a portion of the second flow channel 1003 is a first low-temperature flow channel L1, and at least a portion of the third flow channel 1002 is a second low-temperature flow channel L2. In other words, the first connector 101 has at least a portion of the first high-temperature flow channel G1, and the second connector 102 has the first low-temperature flow channel L1. The two separate structural components are spaced apart and do not have direct contact. Heat is not easily transferred directly between the first connector 101 and the second connector 102, which helps to further reduce the heat transfer between the first high-temperature flow channel G1 and the first low-temperature flow channel L1. The heat transfer between the first high-temperature flow channel G1 and the first low-temperature flow channel L1 in the thermal management system is harmful heat transfer. Reducing harmful heat transfer can further improve the efficiency of the thermal management system.

[0072] In other embodiments, the connecting component 16 can be a flow channel plate assembly composed of plates joined together. The connector 10 is mounted on the flow channel plate assembly, and a portion of the internal interface 1101 of the connector 10 connects to the corresponding interface of the flow channel plate assembly, thereby enabling communication between the flow channel of the connector 10 and the flow channel plate assembly. A heat insulation pad is provided between the connector 10 and the flow channel plate assembly to reduce heat transfer between them. In this embodiment, the connecting component 16 includes connecting pipes, with multiple connecting pipes arranged independently. The connecting pipes are lighter than the flow channel plate assembly, which is beneficial for the weight reduction of the fluid control component. The bending and connecting of the connecting pipes to the connector 10 are also more cost-effective than the processing of the flow channel plate assembly. Furthermore, the independent arrangement and larger spacing between the connecting pipes further reduce harmful heat transfer in the fluid control component.

[0073] The switching components 1301 include multiple components. A first switching component 13011 is mounted on a first connector 101. The first switching component 13011 allows the opening of the first compressor interface 111 to communicate with at least one of the openings of the first interface 113 and the second interface 114. A second switching component 13012 is mounted on a second connector 102. Throttling components 1302 are all mounted on the second connector 102. The second connector 102 has a second high-temperature flow channel G2. The throttling components 1302 can throttle the connection between the second high-temperature flow channel G2 and the first low-temperature flow channel L1. The second connector 102 also has a second low-temperature flow channel L2. The second switching component 13012 can adjust the connection relationship of the second low-temperature flow channel L2, or another second switching component 13012 can adjust the connection relationship of the second high-temperature flow channel G2. The switching component 1301 can be a multi-way valve, which can adjust the connection relationship of multiple different flow channels connected to the corresponding mounting cavity. The second switching component 13012 can be integrated with the throttling component 1302 into a multi-functional component. That is to say, the multi-functional component can both adjust the connection relationship of different flow channels connected to the corresponding mounting cavity and throttle the connection of different flow channels connected to the corresponding mounting cavity.

[0074] In this embodiment, as Figure 7As shown, the first switching component 13011 includes a first valve component 131 and a third valve component 132; the second switching component 13012 includes a second valve component 133; and the throttling component 1302 includes a first throttling component 134 and a second throttling component 135. Specifically, the first throttling component 134 is a battery throttling component, and the second throttling component 135 is a heating throttling component. At least a portion of the first valve component 131 is located in the first mounting cavity 1011, at least a portion of the second valve component 133 is located in the second mounting cavity 1021, at least a portion of the third valve component 132 is located in the third mounting cavity 1012, at least a portion of the first throttling component 134 is located in the first throttling mounting cavity 1022, and at least a portion of the second throttling component 135 is located in the second throttling mounting cavity 1023. In this embodiment, the first valve component 131, the third valve component 132, and the second valve component 133 also have the function of regulating flow rate and can be used to regulate the flow rate of the connected flow path.

[0075] In this embodiment, any two of the first connector 101, the second connector 102, the heat exchange device 14, and the liquid storage device 15 can be connected through the communication component 16. The connector 10 includes an internal interface portion 1101, specifically including a first internal interface portion 11011 and a second internal interface portion 11012. The first internal interface portion 11011 is fixedly connected or limitedly connected to the heat exchange interface portion 141 of the heat exchange device 14 through at least a portion of the communication component 16, thereby enabling the flow channel of the connector 10 to communicate with the heat exchange channel of the heat exchange device 14; the second internal interface portion 11012 is connected through at least a portion of the communication component 16. The connector 10 is fixedly or limitedly connected to the liquid storage interface 51 of the liquid storage device 15, thereby enabling a portion of the flow channel of the connector 10 to communicate with the liquid storage chamber or bypass channel of the liquid storage device 15; the connector 10 also includes an external interface 1102, which is connected to other components in the thermal management system other than the fluid control assembly; the interface 11 connected to the evaporator in the thermal management system is defined as the evaporator interface 1103. In a specific embodiment, part of the evaporator interface 1103 is an internal interface 1101, and the other part of the evaporator interface 1103 is an external interface 1102. Figures 11-16 As shown, the interface portion 11 of the connector 10 includes seven internal interface portions 1101 and five external interface portions 1102. In this embodiment, the fluid control assembly includes a heat exchange device 14, which can be used as an evaporator. The interface portion 11 of the connector 10, which mates with the heat exchange interface portion 141 of the heat exchange device 14, is both an internal interface portion 1101 and an evaporator interface portion 1103. Specifically, the evaporator interface portion 1103 includes a first evaporator interface portion 119 and a second evaporator interface portion 117.

[0076] In a thermal management system, such as Figure 1As shown, the system includes a compressor, a first heat exchanger, a second heat exchanger, and a third heat exchanger. Specifically, the first heat exchanger serves as an external heat exchanger, the second heat exchanger serves as an internal condenser, and the third heat exchanger serves as an internal evaporator. Each component in the thermal management system is fixedly connected to a component of the fluid control assembly, thereby enabling communication between the external thermal management components and the pathways in the fluid control assembly. This allows for the operation of different thermal management modes under the control of the fluid control assembly. Specifically, the external interface 1102 of the connector 10 includes a first compressor interface 111, a second compressor interface 112, an external evaporator interface 122, a first interface 113, and a second interface 114. The opening of the first compressor interface 111 communicates with the compressor outlet, the interface of the second compressor interface 112 communicates with the compressor inlet, the external evaporator interface 122 is connected to the interface of the third heat exchanger, the first interface 113 is connected to the interface of the second heat exchanger, and the second interface 114 is connected to the interface of the first heat exchanger.

[0077] In this embodiment, the external interface portion 1102 is located on the side of the connector 10 away from the heat exchange device 14, and the external interface portion 1102 opens away from the heat exchange device 14. This allows all external thermal management components to connect to the connector 10 from the same direction, facilitating installation. Furthermore, the connector 10 is generally rectangular in shape, including four sides, a bottom side, and a top side. The heat exchange device 14 is located on the bottom side of the connector 10, and the external interface portion 1102 is located on the side of the connector 10 away from the heat exchange device 14, meaning the external interface portion 1102 is located on the top side of the connector 10. In summary, this effectively utilizes the spare perimeter of the connector 10 to arrange the coolant tank 264, improving the space utilization of the fluid control components. Figure 18 As shown, in one specific embodiment, the fluid control assembly may also exclude the coolant tank 264.

[0078] like Figure 11 and Figure 16 As shown, the opening of the first compressor interface 111 is connected to the first sub-flow channel 1001a, the opening of the second compressor interface 112 is connected to the fifth sub-flow channel 1002b, the opening of the first interface 113 is connected to the second sub-flow channel 1001b, the opening of the second interface 114 is connected to the third sub-flow channel 1001c, and the opening of the external evaporator interface 122 is connected to the sixth sub-flow channel 1003a.

[0079] like Figure 6As shown, the internal interface section 1101 includes a first communication interface section 115 and a second communication interface section 116. The first communication interface section 115 and the second communication interface section 116 can be connected and communicated through a partial communication component 16. The opening of the first communication interface section 115 communicates with the third sub-flow channel 1001c, and the opening of the second communication interface section 116 communicates with the fourth sub-flow channel 1002a. The heat exchange device 14 can be used as an evaporator. The first internal interface section 11011 includes a first evaporator interface section 119 and a second evaporator interface section 11011. 117. The eighth interface section 118, the opening of the second evaporator interface section 117 is connected to the fifth sub-flow channel 1002b, the opening of the eighth interface section 118 is connected to the sixth sub-flow channel 1003a, and the opening of the first evaporator interface section 119 is connected to the seventh sub-flow channel 1003b; the second internal interface section 11012 includes a tenth interface section 120 and an eleventh interface section 121, the opening of the tenth interface section 120 is connected to the eighth sub-flow channel 1004a, and the opening of the eleventh interface section 121 is connected to the ninth sub-flow channel 1004b.

[0080] In one operating mode, such as the cooling mode, the first valve component 131 is closed, the third valve component 132 is open, the second valve component 133 is closed, the first throttling component 134 is open, and the second throttling component 135 is closed. The first high-temperature flow channel G1 includes a first sub-flow channel 1001a, a third sub-flow channel 1001c, and a fourth sub-flow channel 1002a. The second high-temperature flow channel G2 includes a sixth sub-flow channel 1003a. The first low-temperature flow channel L1 includes a seventh sub-flow channel 1003b, and the second low-temperature flow channel L2 includes a fifth sub-flow channel 1002b. The refrigerant flowing from the compressor enters the first connector 10 through the opening of the first compressor interface 111, flows through the first sub-channel 1001a and the third sub-channel 1001c, and exits through the opening of the second interface 114. The refrigerant flows through the first heat exchanger, the liquid receiver 15, and the heat exchange device 14, then re-enters the sixth sub-channel 1003a. After being throttled and expanded by the first throttling component 134, it flows through the seventh sub-channel 1003b and re-enters the heat exchange device 14 through the opening of the first evaporator interface 119. After absorbing heat in the heat exchange device 14, it enters the fifth sub-channel 1002b through the opening of the second evaporator interface 117, where it absorbs heat. The heat can be from the battery, effectively cooling the battery. Another portion of the refrigerant in the sixth sub-channel 1003a flows out from the opening of the external evaporator interface 122, expands after being throttled by the external expansion valve, and flows into the third heat exchanger. The refrigerant in the third heat exchanger absorbs heat to cool the passenger compartment. The refrigerant flowing out of the third heat exchanger flows back to the heat exchanger 14 from the opening of the external heat exchange interface 1415. After mixing in the heat exchanger 14, it enters the fifth sub-channel 1002b from the opening of the second evaporator interface 117, and together flows out from the opening of the second compressor interface 112 through the connector 10, returning to the compressor. The second valve component 133 is closed, preventing communication between the fourth sub-channel 1002a in the first high-temperature channel G1 and the fifth sub-channel 1002b in the second low-temperature channel L2.

[0081] In another operating mode, such as heating mode, the first valve component 131 is open, the third valve component 132 is closed, the second valve component 133 is open, the first throttling component 134 is closed, and the second throttling component 135 is open. The first high-temperature flow channel G1 includes a first sub-flow channel 1001a and a second sub-flow channel 1001b, the second high-temperature flow channel G2 includes an eighth sub-flow channel 1004a, the first low-temperature flow channel L1 includes a ninth sub-flow channel 1004b, and the second low-temperature flow channel L2 includes a third sub-flow channel 1001c, a fourth sub-flow channel 1002a, and a fifth sub-flow channel 1002b. The third valve component 132 is closed, so that the first sub-flow channel 1002a in the first high-temperature flow channel G1 is not connected to the third sub-flow channel 1001c in the second low-temperature flow channel L2.

[0082] like Figures 11 to 13As shown, the seventh sub-channel 1003b is farther away from the first connector 101 than the fifth sub-channel 1002b, and the ninth sub-channel 1004b is also farther away from the first connector 101 than the fifth sub-channel 1002b. This further reduces the heat transfer from the first high-temperature channel G1 on the first connector 101 to the first low-temperature channel L1. In other words, the first low-temperature channel L1 and the second low-temperature channel L2 are arranged along the arrangement direction of the first connector 101 and the second connector 102, and the first low-temperature channel L1 is farther away from the first connector 101 than the second low-temperature channel L2.

[0083] It should be noted that the fluid control component can achieve different thermal management modes by switching control parts. A flow channel belongs to different flow channel types in different modes. In this case, if a flow channel is a high-temperature flow channel, it implies that this flow channel is a high-temperature flow channel in a specific operating mode. For example, the fourth sub-flow channel 1002a is the first high-temperature flow channel G1 in cooling mode and the second low-temperature flow channel L2 in heating mode. The second switching component 13012 can adjust the connection relationship of the second low-temperature flow channel L2. This means that when the second switching component 13012 is open, the flow channel connected to the mounting cavity corresponding to the second switching component 13012 can allow refrigerant to flow out of the evaporator. In some thermal management systems, the internal condenser and the external condenser are connected in series. The compressor outlet is connected to the internal condenser inlet, and the internal condenser outlet is connected to the first compressor interface 111 of the fluid control component. It should be explained that in cooling mode, the internal condenser does not work and acts as a channel. In this case, the temperature of the refrigerant at the outlet of the internal condenser is close to the temperature of the refrigerant at the outlet of the compressor. Therefore, the interface of the fluid control component connecting the outlet of the internal condenser can be called the first compressor interface 111. Furthermore, the flow channel between the outlet of the internal condenser and the inlet of the external condenser can also be called the first high-temperature flow channel G1. In heating mode, the internal condenser works and the external condenser does not work. The flow channel connecting the outlet of the internal condenser and the inlet of the external condenser is called the second high-temperature flow channel G2.

[0084] like Figure 5As shown, the connecting component 16 includes multiple separate connecting pipes and has multiple connecting channels that extend through both ends of the connecting pipes. Specifically, the connecting component 16 includes a first connecting pipe 1601, one end of which is connected to a first connecting interface 115, and the other end is connected to a second connecting interface 116, thereby connecting the third sub-flow channel 1001c and the fourth sub-flow channel 1002a. One end of the second connecting pipe 1602 is connected to a first internal interface 11011 of the connector 10, and the other end is fixedly or limitingly connected to the heat exchange interface 141 of the heat exchange device 14. Specifically, the second connecting pipe 1602 includes a first sub-connecting pipe 16. 02a, second sub-connecting pipe 1602b, third sub-connecting pipe 1602c; one end of the first sub-connecting pipe 1602a is connected to the second evaporator interface 117, and the other end is connected to the fourth heat exchange interface 1414, so that the fifth sub-flow channel 1002b is connected to the second heat exchange channel 1402; one end of the second sub-connecting pipe 1602b is connected to the eighth interface 118, and the other end is connected to the second heat exchange interface 1412; the sixth sub-flow channel 1003a is connected to the first heat exchange channel 1401; one end of the third sub-connecting pipe 1602c... The first evaporator interface 119 is connected at one end, and the third heat exchange interface 1413 is connected at the other end. The seventh sub-flow channel 1003b is connected to the other end of the second heat exchange channel 1402. One end of the third connecting pipe 1603 is connected to the partial liquid storage interface 51, and the other end is connected to the second internal interface 11012 of the connector 10 and / or to the heat exchange interface of the heat exchange device 14. The third connecting pipe 1603 includes a fourth sub-connecting pipe 1603a and a fifth sub-connecting pipe 1603b. The fourth sub-connecting pipe 1603a is a three-way pipe. The first end of the fourth sub-connecting pipe 1603a is connected to the outlet 513, the second end of the fourth sub-connecting pipe 1603a is connected to the first heat exchange interface 1411, and the third end of the fourth sub-connecting pipe 1603a is connected to the tenth interface 120, so that the liquid storage chamber is connected to the first heat exchange channel 1401 and the eighth sub-flow channel 1004a respectively. One end of the fifth sub-connecting pipe 1603b is connected to the third opening 514, and the other end is connected to the eleventh interface 121, so that the bypass channel is connected to the ninth sub-flow channel 1004b.

[0085] In other embodiments, the heat exchange device 14 may include a first heat exchange device and a second heat exchange device. The first heat exchange device serves as a condenser, and the second heat exchange device serves as an evaporator. A portion of the second connecting pipe 1602 has its two ends connected to the first connector 101 and the first heat exchange device, respectively, so that the first high-temperature flow channel G1 is connected to the heat exchange channel of the first heat exchange device. Another portion of the second connecting pipe 1602 has its two ends connected to the second connector 102 and the second heat exchange device, respectively, so that the first low-temperature flow channel L1 is connected to the heat exchange channel of the second heat exchange device. Furthermore, when the second connector 102 is provided with a second high-temperature flow channel G2, the first heat exchange device can be connected to the second high-temperature flow channel G2 through another second connecting pipe 1602, and the first heat exchange device can be connected to the second connector 102.

[0086] In this embodiment, the openings of the connecting component 16 face the same direction, and the connecting component 16 is fixedly or limitedly connected to the connector 10, the liquid storage device 15, and the heat exchange device 14 in the same direction. That is, the openings of the first connecting interface 115 and the second connecting interface 116 face the same direction, which facilitates the fixed or limited connection of the first connecting pipe 1601 to the separate first connector 101 and the second connector 102 from the same direction. The opening of the first internal interface 11011 faces the same direction as the opening of the heat exchange interface 141, which facilitates the fixed or limited connection of the second connecting pipe 1602 to the connector 10 and the heat exchange device 14 from the same direction. The opening of the second internal interface 11012 faces the same direction as the opening of at least part of the liquid storage interface 51, which facilitates the fixed or limited connection of the third connecting pipe 1603 to the connector 10 and the liquid storage device 15 from the same direction. In this embodiment, along the stacking direction of the plates of the heat exchange device 14, the connecting assembly 16 is located on the same side of the connector 10, the heat exchange device 14, and the liquid storage device 15. The openings of the first internal interface portion 11011, the second internal interface portion 11012, at least a portion of the heat exchange interface portion 141, and at least a portion of the liquid storage interface portion 51 are oriented in the same direction, which facilitates the installation of the connecting assembly 16. The connecting pipe of the connecting assembly 16 is generally U-shaped. Specifically, the connecting assembly 16 includes a welded connecting pipe and a swivel connecting pipe. The welded connecting pipe includes a first connecting pipe 1601 and a second connecting pipe 1602, and the swivel connecting pipe includes a third connecting pipe 1603. The first connecting pipe 1601 and the second connecting pipe 1602 are located on the same side of the supporting base 26, and a portion of the third connecting pipe 1603 is located on the opposite side of the supporting base 26. The supporting base 26 includes a clearance portion B, and a portion of the third connecting pipe 1603 is located in the clearance portion B. Welding grooves are provided at both ends of the specific welded connecting pipe, extending axially along the connecting pipe. In other words, a wire-drawing process is applied to both ends of the welded connecting pipe. When the two ends of the welded connecting pipe are located in the chamber of the interface 11 and welded together, the welding grooves improve welding performance. The welding can be induction welding. Connecting joints are welded to both ends of the union connecting pipe, which are then bolted to the corresponding liquid storage device 15 or heat exchange device 14. In this embodiment, the liquid storage device 15 is first fixed to the supporting base 26 of the second module 2, and then the connecting piece 10 of the first module 1 and the heat exchange device 14 are fixed to the supporting base 26. The third connecting pipe 1603 is configured as a union connecting pipe to facilitate the installation and connection of the fluid control components.

[0087] Example 2

[0088] Figures 18-30 A second fluid control component is provided. The difference between this embodiment and the first embodiment is that the fluid control component in this embodiment includes a first module 1. The structure of the first module 1 is similar to that of the first module 1 in the first embodiment. The differences will be highlighted below.

[0089] like Figure 18 As shown, the fluid control component includes a support frame 3, which includes strip-shaped structural members. The support frame 3 has sufficient support strength. No flow channels are provided on the support frame 3, so the pressure resistance of the support frame 3 does not need to be considered. The material of the support frame 3 is metal, generally cast iron or sheet metal. Cast iron and sheet metal have mature processing technology and low manufacturing cost, which helps to reduce the manufacturing cost of the fluid control component.

[0090] The support frame 3 includes a fixing part 262, and the connector 10 and heat exchange device 14 each include a mating part 17. The mating part 17 corresponds one-to-one with the fixing part 262, and the mating part 17 and the fixing part 262 are fixedly connected. Specifically, the fixing part 262 and the mating part 17 are detachably bolted together. The heat exchange device 14 and the connector 10 are fixed to the support frame 3 by fasteners. The support frame 3 also includes a first groove, which can be described as a blind hole structure. The fluid control component includes a pin, and the connector 10 includes a limiting groove 19, which is also a blind hole structure. The first groove and the limiting groove 19 correspond one-to-one, and their axes overlap. The pin is located in the first groove and the limiting groove 19 respectively. This structure plays a pre-positioning role when the connector 10 is bolted to the support frame 3. After the bolt connection, it can further prevent relative displacement between the connector 10 and the support frame 3. The limiting groove 19 can also be provided on the heat exchange device 14, which plays a predetermined role in the installation of the heat exchange device 14.

[0091] like Figure 20 and Figure 24As shown, the first connector 10 includes a columnar portion, the inner cavity of which is used to mount the control component 13 or the sensor T. That is, at least part of the inner cavity of the columnar portion is the mounting cavity of the connector 10 described above. In this embodiment, the sensor T is not mounted on the connector 10. When there are multiple control components 13, there are correspondingly multiple columnar portions. When there is a communication relationship between the inner cavities of the columnar portions, a channel portion is provided between the columnar portions. When there is no communication relationship between the inner cavities of the columnar portions, the columnar portions are connected by a connecting plate. The mating portion 17 and the limiting groove portion 19 are also plate-shaped structures, which helps to reduce the weight of the connector 10 and, on the other hand, helps to reduce heat transfer between different columnar bodies of the connector 10. Specifically, the mating parts 17 include a first mating part 171, a second mating part 172, a third mating part 173, a fourth mating part 174, a fifth mating part 175, a sixth mating part 176, and a seventh mating part 177. Three of these mating parts 17 are located on the first connector 101, and the other four are located on the second connector 102. The mating parts 17 are distributed around the periphery of the connector 10 in a claw-like pattern. In other words, each mating part 17 has a separate structure near the end of the supporting frame 3. Alternatively, the connector 10 includes a heat insulation part R. The first mating part 171 and the second mating part 172 are arranged adjacent to each other. The end of the first mating part 171 near the supporting frame 3 is located on one side of the heat insulation part R, and the end of the second mating part 172 near the supporting frame 3 is located on the other side of the heat insulation part R. This effectively reduces heat transfer between the mating parts 17 and between the entire connector 10 and the supporting frame 3. Only a portion of the heat is transferred between the mating parts 17 through the supporting frame 3 or from the first connector 101 to the second connector 102. If the first mating part 171 is adjacent to a limiting groove part 19, the first mating part 171 may be located on one side of the heat insulation part R, and the adjacent limiting groove part 19 may be located on the other side of the heat insulation part R. This reduces the heat transfer between the first mating part 171 and the limiting groove part 19, and also reduces the heat transfer between the connecting block 10 and the supporting frame 3.

[0092] The fluid control assembly includes a clamp, which is a long strip plate surrounding the liquid storage device 15. Both ends of the clamp have mating portions 17 that engage with corresponding fixing portions 262 on the support frame 3. Fasteners bolt the mating portions 17 of the clamp to the fixing portions 262 of the support frame 3. After the fasteners are installed, the clamp is tightly fitted to the liquid storage device 15 in the radial direction, thus fixing the liquid storage device 15 to the support frame 3 in the radial direction. Additionally, some fixing portions 262 of the support frame 3 are bent. The end cap of the liquid storage device 15 includes a mating portion 17, and the bent fixing portion 262 is fixedly connected to the mating portion 17 of the end cap, facilitating axial fixation of the liquid storage device 15.

[0093] Viewing the fluid control assembly from one side of the connecting component 16, as shown... Figure 6 and Figure 20 As shown, in Embodiment 1, the control component X, heat exchange device 14, and liquid storage device 15 are arranged clockwise, while in Embodiment 2, the control component X, heat exchange device 14, and liquid storage device 15 are arranged counterclockwise.

[0094] In this embodiment, the heat exchange device 14 includes a second heat exchange channel 1402 (not shown) and a third heat exchange channel 1403. The second heat exchange channel 1402 allows refrigerant to flow in from the flow channel of the connector 10, while the third heat exchange channel 1403 allows coolant, such as water, to flow through it. The medium in the second heat exchange channel 1402 can exchange heat with the medium in the third channel. The heat exchange device 14 is a plate heat exchanger, such as... Figure 20 As shown, the heat exchange device 14 includes a third heat exchange interface 1413 and a fourth heat exchange interface 1414. One end of the second heat exchange channel 1402 is connected to the opening of the third heat exchange interface 1413, and the other end is connected to the opening of the fourth heat exchange interface 1414. The two ends of the third heat exchange channel 1403 are connected to the opening of the coolant inlet and the opening of the coolant outlet, respectively. In this embodiment, the heat exchange device 14 can be used as an evaporator or a condenser, enabling battery heating mode and battery cooling mode. When the fourth valve component 137 is open and the fifth valve component 138 is closed, the refrigerant flowing in from the first compressor interface 111 can flow to the second heat exchange channel 1402 of the heat exchange device 14. At this time, the heat exchange device 14 is used as a condenser. When the fourth valve component 137 is closed and the fifth valve component 138 is open, the refrigerant flowing through the heat exchange device 14 flows from the seventeenth interface 127 to the liquid storage device 15. After gas-liquid separation in the liquid storage device 15, the gaseous refrigerant flows back to the compressor.

[0095] The liquid storage device 15 has a liquid storage chamber that can communicate with the flow channel of the connector 10. The liquid storage device 15 includes an upper end cap, a cylinder, and a lower end cap. Along the axial direction of the cylinder, the upper end cap is located above the cylinder, and the lower end cap is located below the cylinder. The upper end cap and the lower end cap are respectively provided with liquid storage interface portions 51, specifically including a first opening portion 511, a second opening portion 512, a third opening portion 514, and an outlet portion 513. In this embodiment, the liquid storage device 15 has gas-liquid separation function and heat exchange function. That is, the liquid storage device 15 includes an internal heat exchange channel. Refrigerant flowing in from the condenser outlet flows through the internal heat exchange channel. The gaseous refrigerant in the liquid storage chamber of the liquid storage device 15 can absorb the heat of the refrigerant in the internal heat exchange channel. The gaseous refrigerant that has absorbed the heat flows out from the outlet portion 513 and returns to the compressor inlet, which can reduce the liquid slugging phenomenon of the compressor and improve the operating efficiency of the compressor.

[0096] The upper end cap includes a first opening 511 and a third opening 514, while the lower end cap includes a second opening 512 and an outlet 513. One end of the internal heat exchange channel communicates with the opening of the second opening 512, and the other end communicates with the opening of the third opening 514. In one specific embodiment, the wall forming the internal heat exchange channel can be a spiral tube coiled in the liquid storage chamber of the liquid storage device 15, or the internal heat exchange channel can be integrated into the cylinder. The upper end cap includes a first inlet channel, one end of which communicates with the opening of the seventeenth interface 127, and the other end communicates with the liquid storage chamber. The lower end cap includes an outlet channel, one end of which communicates with the opening of the outlet 513, and the other end communicates with the gas phase region of the liquid storage chamber. The gaseous refrigerant in the liquid storage chamber can flow out through the opening of the outlet 513. In one specific embodiment, the openings of the first opening 511 and the third opening 514 are axially oriented towards the liquid storage device 15, and the openings of the outlet 513 and the second opening 512 are radially oriented towards the liquid storage device 15. Specifically, the opening of the second opening 512 is oriented towards the connecting component 16, and the opening of the outlet 513 is away from the connecting component 16.

[0097] In this embodiment, the first switching component 13011 further includes a fourth valve component 137, the second switching component 13012 further includes a fifth valve component 138, and the throttling component 1302 further includes a third throttling component 136. Compared with Embodiment 1, this makes the functional modes of the thermal management system more diverse. The third throttling component 136 is an expansion valve located before the internal evaporator. It was not integrated in Embodiment 1, but it is integrated in this embodiment, reducing the scattered arrangement of control components 13 in the thermal management system and improving the integration of the fluid control components. The fourth valve component 137 and the fifth valve component 138 enable the fluid control components to achieve battery heating mode.

[0098] The flow channels of the connector 10 include a first flow channel 1001, a second flow channel 1003, a third flow channel 1002, and a fourth flow channel 1004. Unlike the previous embodiment, the first flow channel 1001 further includes a tenth sub-flow channel 1001d. A seventh mounting cavity 1025 is located and communicates with the first flow channel 1001. The first sub-flow channel 1001a communicates with the first mounting cavity 1011, the second mounting cavity 1012, and the seventh mounting cavity 1025. The tenth sub-flow channel 1001d communicates with the seventh mounting cavity 1025. The fourth valve component 137 can connect or disconnect the first sub-flow channel 1001a and the tenth sub-flow channel 1001d. The third flow channel 1002 includes an eleventh sub-flow channel 1002c, and a fifth sub-flow channel 1002b communicates with the eighth mounting cavity 1013. The second mounting cavity 1021 is connected, the eleventh sub-flow channel 1002c is connected to the eighth mounting cavity 1013, and the fifth valve component 138 can connect or disconnect the eleventh sub-flow channel 1002c and the fifth sub-flow channel 1002b; the second flow channel 1003 includes the twelfth sub-flow channel 1003c, the sixth sub-flow channel 1003a is connected to both the first throttling mounting cavity 1022 and the sixth mounting cavity 1024, the twelfth sub-flow channel 1003c is connected to the sixth mounting cavity 1024, and the third throttling component 136 can connect, disconnect or throttle the twelfth sub-flow channel 1003c and the sixth sub-flow channel 1003a.

[0099] In this embodiment, the interface portion 11 of the connector 10 includes eight internal interface portions 1101 and seven external interface portions 1102. The internal interface portions 1101 include a first communication interface portion 115 and a second communication interface portion 116. The first internal interface portion 11011 includes a first evaporator interface portion 119, a second evaporator interface portion 117, and a third communication interface portion 128. The second internal interface portion 11012 includes an eighth interface portion 118, a fifteenth interface portion 125, and a seventeenth interface portion 127. The external interface section 1102 includes a first compressor interface section 111, a first interface section 113, a second interface section 114, a thirteenth interface section 123, a fourteenth interface section 124, a second external evaporator interface section 126, and an external evaporator interface section 122. The first interface section 113 and the thirteenth interface section 123 are respectively connected to the two ends of the second heat exchanger. The second interface section 114 and the fourteenth interface section 124 are respectively connected to the two ends of the first heat exchanger. The external evaporator interface section 122 and the second external evaporator interface section 126 are respectively connected to the two ends of the third heat exchanger. The first compressor interface section 111 is connected to the outlet of the compressor. In this embodiment, the refrigerant flows back from the outlet section 513 of the liquid storage device 15 to the inlet of the compressor.

[0100] The differences between the two embodiments are described in detail below: In Embodiment 1, the opening of the second evaporator interface 117 is directly connected to the fifth sub-channel 1002b. In this embodiment, the fifth valve component 138 is opened, and the fifth sub-channel 1002b is connected to the eleventh sub-channel 1002c, which in turn is connected to the opening of the second evaporator interface 117. The opening of the seventeenth interface 127 is connected to the fifth sub-channel 1002b. In Embodiment 1, the opening of the external evaporator interface 122 is connected to the sixth sub-channel 1003a. In Embodiment 1, the corresponding third heat exchanger is not integrated. The corresponding throttling component 1302, in this embodiment, integrates a third throttling component 136. When the third throttling component 136 is opened, the refrigerant in the sixth sub-channel 1003a can be throttled and flow to the twelfth sub-channel 1003c, and then flow to the third heat exchanger from the opening of the external evaporator interface 122. In this embodiment, the opening of the third communication interface 128 is connected to the tenth sub-channel 1001d, and the fourth valve component 137 is opened, so that the first sub-channel 1001a is connected to the tenth sub-channel 1001d and then to the opening of the third communication interface 128. The opening of the fifteenth interface 125 is connected to the eighth sub-channel 1004a. In heating mode, refrigerant flows into the connector 10 from the opening of the thirteenth interface 123. The second throttling component 134 is opened, and the eighth sub-channel 1004a and the ninth sub-channel 1004b are connected by throttling. The refrigerant flows out of the connector 10 from the opening of the fourteenth interface 124. In cooling mode, refrigerant flows into the connector 10 from the opening of the fourteenth interface 124. The second throttling component 135 is opened, and the eighth sub-channel 1004a and the ninth sub-channel 1004b are connected. The refrigerant does not undergo throttling expansion. The refrigerant flows from the opening of the fifteenth interface 125 to the internal heat exchange channel of the liquid storage device 15.

[0101] like Figure 20As shown, the connecting component 16 includes a first connecting pipe 1601, a first sub-connecting pipe 1602a, a third sub-connecting pipe 1602c, a sixth sub-connecting pipe 1603c, a seventh sub-connecting pipe 1603d, and an eighth sub-connecting pipe 1603e. The second interface 114 is separately set from the first connector 101. The separate setting increases the freedom of setting the second interface 114. The first connecting pipe 1601 has a three-way structure. The first connecting pipe 1601 is fixedly connected or limited to the first connecting interface 115 and the second connecting interface 116 respectively. The third end of the first connecting pipe 1601 is connected to the second interface 114. The first connector 101, the second connector 102, and the first interface 114, which are set separately at intervals, are connected into one unit through the first connecting pipe 1601. The structure of the connecting pipe can effectively reduce the heat transfer between the three. The first sub-connecting pipe 1602a has a three-way structure. The first sub-connecting pipe 1602a is connected to the second evaporator interface 117 and the fourth heat exchange interface 1414 respectively. The third end of the first sub-connecting pipe 1602a is connected to the third connecting interface 128, so that the tenth sub-flow channel 1001d and the eleventh flow channel 1002c can be connected to the second heat exchange channel 1402 (not shown). In this embodiment, the first sub-connecting pipe 1602a is a branch connecting pipe of the second connecting pipe 1602. It can connect the flow channel of the connector 10 and the heat exchange channel of the heat exchange device 14, but it can also connect the flow channel of the first connector 101 and the flow channel of the second connector 102. It is equivalent to the second connecting pipe 1602 integrating the functional part of the first connecting pipe 1601. It should be noted that when describing the function of the second connecting pipe 1602 connecting the first connector 101 and the second connector 102, the second evaporator interface 117 can also be called the fourth connecting interface. The third sub-connecting pipe 1602c includes a mounting block, which is a three-way structure. The third sub-connecting pipe 1602c is connected through a channel within the mounting block. A sensor T (not shown) is mounted on the mounting block. The sensor T can detect the temperature and / or pressure of the medium flowing within the third sub-connecting pipe 1602c. The mounting block facilitates the installation of the sensor T. One end of the sixth sub-connecting pipe 1603c is connected to the fifteenth interface 125, and the other end is connected to the second opening 512 of the liquid storage device. 603c can connect the eighth sub-channel 1004a and the inner displacement heat channel; one end of the seventh sub-connecting pipe 1603d is connected to the third opening 514 and the other end is connected to the eighth interface 118, and the seventh sub-connecting pipe 1603d can connect the inner displacement heat channel and the sixth sub-channel 1003a; one end of the eighth sub-connecting pipe 1603e is connected to the seventeenth interface 127 and the other end is connected to the first opening 511, and the eighth sub-connecting pipe 1603e can connect the fifth sub-channel 1002b and the liquid storage chamber.

[0102] In this embodiment, the multiple control components 13 of the connector 10 are arranged in an alternating manner, and the corresponding multiple mounting cavities are also arranged in an alternating manner. For example, along the arrangement direction of the first connector 101 and the second connector 102, the second valve component 132 and the third valve component 133 are located in one row, and the fourth valve component 137 and the fifth valve component 138 are located in another row. Figure 20 and Figure 21 As shown, this arrangement ensures that the first connecting pipe 1601 and the first sub-connecting pipe 1602a are arranged at least partially in parallel, and the distance between the parallel segments is short, making the fluid control assembly structure compact. Specifically, the distance between the parallel pipe segments of the first connecting pipe 1601 and the first sub-connecting pipe 1602a is less than the sum of the maximum radius of the second mounting cavity 1012 and the maximum radius of the fourth mounting cavity 1022.

[0103] In this embodiment, the liquid storage device 15 and the heat exchange device 14 are not connected by a connecting component 16. Along the axial direction of the liquid storage device 15, a portion of the seventh sub-connecting pipe 1603d and a portion of the eighth sub-connecting pipe 1603e are arranged above the liquid storage device 15. In this embodiment, the welded connecting pipe includes a first connecting pipe 1601, and the detachable connecting pipe includes a sixth sub-connecting pipe 1603c, a seventh sub-connecting pipe 1603d, and an eighth sub-connecting pipe 1603e. The first sub-connecting pipe 1602a and the third sub-connecting pipe 1602c have a welded connection at the end connected to the connector 10 and a bolted connection at the end connected to the heat exchange device 14. This arrangement facilitates the adjustment of the positional error during installation of the heat exchange device 14 and the liquid storage device 15 on the supporting frame 3 through a detachable connection.

[0104] It should be noted that the above embodiments are only used to illustrate this application and are not intended to limit the technical solutions described in this application. Although this specification has described this application in detail with reference to the above embodiments, those skilled in the art should understand that they can still make modifications or equivalent substitutions to the application. All technical solutions and improvements that do not depart from the spirit and scope of this application should be covered within the scope of the claims of this application.
