[0016] The present application will be further described below with reference to the accompanying drawings and specific embodiments:

[0017] See Figure 1The fluid control component can be applied in a thermal management system, which can be a vehicle thermal management system, specifically a new energy vehicle thermal management system. The fluid control component 100 includes a valve element and a valve block 1. The valve element and valve block 1 are fixedly connected or limit-connected. Furthermore, a sealing arrangement can be provided between the valve element and valve block 1 to reduce leakage of the working fluid from the assembly gap between the valve element and valve block 1. In this embodiment, the valve element includes a first valve element 21 and a second valve element 22. The first valve element 21 has a multi-way reversing function, such as a four-way reversing valve, enabling two-way conduction between different channels of the fluid control component 100. The second valve element 22 has direct-flow and throttling functions, such as a multi-way throttling valve, capable of connecting or disconnecting two or more different channels of the fluid control component 100. When connected, it can either allow direct flow or throttle the flowing working fluid. Connectivity is defined as having two states: direct flow and throttling. Direct flow does not change the pressure of the flowing working fluid, while throttling changes the pressure of the flowing working fluid.

[0018] See Figures 1 to 3The valve block 1 has mounting cavities, and the number of mounting cavities can be multiple. In this embodiment, the mounting cavities include a first mounting cavity 31 and a second mounting cavity 32. The openings of the first mounting cavity 31 and the second mounting cavity 32 are located on the first side of the outer wall surface of the valve block 1, facilitating the installation of the valve element and the valve block 1. A portion of the first valve element 21 is located in the first mounting cavity 31, and the first valve element 21 is fixedly connected or limitedly connected to the first mounting portion forming the first mounting cavity 31. A portion of the second valve element 22 is located in the second mounting cavity 32, and the second valve element 22 is fixedly connected or limitedly connected to the second mounting portion forming the second mounting cavity 32. The fluid control assembly 100 has channels, and the number of channels can be multiple. The first valve element 21 has two or more working positions, enabling two or more channels to be connected. The second valve element 22 can connect or not connect two or more channels, and when connected, it can straighten or throttle the flowing working fluid. In this embodiment, the channels include a first channel 41, a second channel 42, a third channel 43, a fourth channel 44, a fifth channel 45, and a sixth channel 46. The first channel 41 has a first interface 411 for connecting to a system pipeline. The opening of the first interface 411 is located on the second side of the outer wall of the valve block 1 or flush with the second side of the outer wall of the valve block 1. The second channel 42 has a second interface 421 for connecting to a system pipeline. The opening of the second interface 421 is located on the third side of the outer wall of the valve block 1 or flush with the third side of the outer wall of the valve block 1, wherein the second and third sides are arranged opposite to each other. The third channel 43 has a third interface 431 for connecting to a system pipeline. The opening of the third interface 431 is located on the fourth side of the outer wall of the valve block 1 or flush with the fourth side of the outer wall of the valve block 1. The fourth channel 44 has a fourth interface 441 for connecting to a system pipeline. The opening of the fourth interface 441 is located on the fifth side of the outer wall of the valve block 1 or flush with the fifth side of the outer wall of the valve block 1, wherein the fourth and fifth sides are arranged opposite to each other. The valve block 1 is arranged side-to-side with the central axis of the first channel 41 and the central axis of the second channel 42, which can coincide or nearly coincide. The central axis of the third channel 43 and the central axis of the fourth channel 44 can coincide or nearly coincide. The central axis of the first channel 41 and the central axis of the third channel 43 can be perpendicular or nearly perpendicular. This helps to reduce the flow path of the channels and facilitates the miniaturization of the valve block 1. The sixth channel 46 is connected to the fourth channel 44. The central axis of the fifth channel 45 and the central axis of the sixth channel 46 can coincide or nearly coincide. The central axis of the sixth channel 46 and the central axis of the fourth channel 44 can be perpendicular or nearly perpendicular. This helps to reduce the flow path of the sixth channel 46 and the fourth channel 44. The fifth channel 45 has a fifth interface 451, which is used to connect with the system pipeline. The opening of the fifth interface 451 is located on the sixth side of the outer wall of the valve block 1 or is flush with the sixth side of the outer wall of the valve block 1.Setting different interfaces on different sides of valve block 1 helps to avoid the risk of incorrect connection and also helps to reduce the size of valve block 1.

[0019] See Figure 3 In this embodiment, the first valve element 21 is a four-way directional valve, such as a four-way directional ball valve. The valve core of the first valve element 21 has channels, including a first channel 211 and a second channel 212. The first valve element 21 has a first working position and a second working position. When the first valve element 21 is in the first working position, the first valve element 21 connects the first channel 41 and the third channel 43 through the first channel 211, and connects the second channel 42 and the fourth channel 44 through the second channel 212. When the first valve element 21 is in the second working position, the first valve element 21 can connect the first channel 41 and the fourth channel 44 through the first channel 211, and connect the second channel 42 and the third channel 43 through the second channel 212. Of course, as in other embodiments, depending on the needs of the system, the first valve element 21 can also be a three-way directional valve or other multi-way directional valve, and the number of channels can also be other. In this embodiment, the second valve element 22 is a two-way throttle valve, such as a two-way throttle ball valve. The second valve element 22 can connect or disconnect the fifth channel 45 and the sixth channel 46, and can directly or throttle the working fluid flowing through the fifth channel 45 and the sixth channel 46 by adjusting the opening of the second valve element 22. Specifically, the second valve element 22 has a third channel 221 and a throttling groove 222, which are connected. Of course, in other embodiments, the third channel 221 and the throttling groove 222 may not be connected. The flow cross-sectional area of ​​221 is much larger than that of the throttling groove 222. When the second valve element 22 connects the fifth channel 45 and the sixth channel 46 through the third channel 221, the fifth channel 45 and the sixth channel 46 are directly connected. When the second valve element 22 connects the fifth channel 45 and the sixth channel 46 through the third channel 221 and the throttling groove 222, or vice versa, the fifth channel 45 and the sixth channel 46 are throttled and connected. The second valve element 22 changes the pressure of the working fluid flowing through the fifth channel 45 and the sixth channel 46 through the throttling groove 222. "Much larger" is defined as: the flow cross-sectional area of ​​the third channel 221 is S1, the maximum flow cross-sectional area of ​​the throttling groove 222 is S2, and the two satisfy the relationship S1 / S2≥9.

[0020] See Figure 3In this embodiment, the fluid control assembly 100 further includes a one-way valve 5, which is located in the fourth channel 44. Along the axial direction of the fourth channel 44, the communication port of the sixth channel 46 connecting to the fourth channel 44 is positioned closer to the opening of the fourth interface 441 than the one-way valve 5. The fourth interface 441 is located on the back pressure side of the one-way valve 5. The one-way valve 5 is fixedly connected or limited to the valve block 1. The one-way valve 5 can be provided according to the needs of the system's operating mode. Of course, in other embodiments, the fluid control assembly 100 may not include the one-way valve 5.

[0021] See Figures 1 to 5The fluid control assembly 100 also includes a gas-liquid separation element 6, which is fixedly connected or limited to the valve block 1. In this embodiment, the gas-liquid separation element 6 and the valve block 1 are fixedly connected by screws. Furthermore, a sealing arrangement can be provided between the gas-liquid separation element 6 and the valve block 1 to prevent leakage of the working fluid from the assembly gap between them. Along the axial direction of the gas-liquid separation element 6, the valve element and the gas-liquid separation element 6 are located on opposite sides of the valve block 1, which helps to make the fluid control assembly 100 structurally compact. The fluid control assembly 100 has a gas-liquid separation chamber, at least a portion of which is located within the gas-liquid separation element 6. The gas-liquid separation chamber communicates with at least one of the channels. The gas-liquid separation element 6 separates the gas and liquid phases of the working fluid through the gas-liquid separation chamber. In this embodiment, the gas-liquid separation chamber is located within the gas-liquid separation element 6. Of course, in other embodiments, the gas-liquid separation chamber can also be formed jointly by connecting the gas-liquid separation element and the valve block. In this embodiment, the valve block 1 further includes a seventh channel 47 and an eighth channel 48. The seventh channel 47 is connected to the second channel 42. The central axis of the seventh channel 47 may be perpendicular or nearly perpendicular to the central axis of the second channel 42. The seventh channel 47 has a sixth interface 471. The opening of the sixth interface 471 is located on the seventh side of the outer wall of the valve block 1 or is flush with the seventh side of the outer wall of the valve block 1. The sixth interface 471 is used to connect with the gas-liquid separation element 6. The eighth channel 48 is separately disposed through the valve block 1. The central axis of the eighth channel 48 may be parallel or nearly parallel to the central axis of the seventh channel 47. The eighth channel 48 has a seventh interface 481 and an eighth interface 482. The opening of the seventh interface 481 may be located on the seventh side of the outer wall of the valve block 1 or is flush with the seventh side of the outer wall of the valve block 1. The seventh interface 481 is used to connect with the gas-liquid separation element 6. The opening of the eighth interface 482 may be located on the first side of the outer wall of the valve block 1 or is flush with the first side of the outer wall of the valve block 1. The eighth interface 482 is used to connect with the system pipeline. Accordingly, the gas-liquid separation element 6 includes an inlet connector 61 and an outlet connector 62. The inlet connector 61 has an inlet 611, and the outlet connector 62 has an outlet 621. The inlet 611 and the outlet 621 are respectively connected to the gas-liquid separation chamber of the gas-liquid separation element 6. The working fluid enters from the inlet 611, and after gas-liquid two-phase separation, the liquid phase working fluid is located inside the gas-liquid separation element 6, and the gas phase working fluid flows out from the outlet 621 and flows to a subsequent circuit such as a compressor. When the gas-liquid separation element 6 is connected to the valve block 1, at least part of the inlet connector 61 is located in the seventh channel 47, and the inlet connector 61 is mated with the sixth interface 471, and the inlet 611 is connected to the seventh channel 47. At least part of the outlet connector 62 is located in the seventh interface 481, and the outlet connector 62 is mated with the seventh interface 481, and the outlet 621 is connected to the eighth channel 48. Furthermore, a sealing arrangement can be made between the inlet connector 61 and the sixth interface 471 and / or between the outlet connector 62 and the seventh interface 481 to prevent leakage of the working fluid.

[0022] The fluid control component 100 can be applied to a thermal management system, specifically an air conditioning system within the thermal management system. (See [link to relevant documentation]). Figures 6 to 8 This is one embodiment of the fluid control component 100 applied to a thermal management system. The thermal management system includes a compressor 201, an indoor condenser 202, an indoor evaporator 203, an outdoor heat exchanger 204, and a throttling valve 205. The outlet of the compressor 201 is connected to one interface of the indoor condenser 202, and the other interface of the indoor condenser 202 is connected to a first interface 411 of the fluid control component 100. One interface of the outdoor heat exchanger 204 is connected to a third interface 431, and the other interface of the outdoor heat exchanger 204 is connected to a fifth interface 451. One interface of the throttling valve 205 is connected to a fourth interface 441, and the other interface of the throttling valve 205 is connected to one interface of the indoor evaporator 203. The other interface of the indoor evaporator 203 is connected to a second interface 421, and the eighth interface 482 is connected to the inlet of the compressor 201. The fluid control component 100 applied to the thermal management system includes, but is not limited to, three operating modes:

[0023] First working mode: First valve element 21 is in the first working position, second valve element 22 is open and in a straight-through state. At this time, first channel 41 is connected to third channel 43 through first valve element 21, second channel 42 is connected to fourth channel 44 through first valve element 21, and fifth channel 45 is connected to sixth channel 46 through second valve element 22.

[0024] At this time, the high-temperature and high-pressure working fluid (such as refrigerant) at the outlet side of compressor 200 flows through the indoor condenser 202, condenses and dissipates heat, and then flows into the first channel 41 through the first interface 411. It then flows out through the third interface 431 of the third channel 43 via the first valve element 21, flowing towards the outdoor heat exchanger 204. After further heat exchange and condensation in the outdoor heat exchanger 204, it flows into the fifth channel 45 through the fifth interface 451, and then flows into the sixth channel 46 via the second valve element 22. The high-pressure working fluid in the sixth channel 46 flows into the fourth channel 44 and is located on the back pressure side of the check valve 5. Under the reverse flow control of valve 5, the working fluid located in the sixth channel 46 flows out from the fourth port 441, and after being throttled by the throttling valve 205 (at this time, the throttling valve 205 is open), it becomes a low-temperature, low-pressure working fluid and flows to the indoor evaporator 203. After evaporation and heat absorption by the indoor evaporator 203, the low-pressure working fluid flows into the second channel 42 through the second port 421, and then into the gas-liquid separation element 6 through the seventh channel 47. After gas-liquid separation by the gas-liquid separation element 6, the gas phase working fluid flows into the eighth channel 48, and then flows back to the inlet of the compressor 201 from the eighth port 482 for recirculation. It should be noted that since the working fluid flowing into the second channel 42 is a low-pressure working fluid, that is, the working fluid flowing into the fourth channel 44 through the first valve element 21 and located on the forward pressure side of the check valve 5 is a low-pressure working fluid, while the working fluid located on the back pressure side of the check valve 5 is a high-pressure working fluid, under the action of the pressure difference, the check valve 5 is in the closed state at this time.

[0025] Second working mode: The first valve element 21 is in the second working position, the second valve element 22 is open and in a throttling state. At this time, the first channel 41 is connected to the fourth channel 41 through the first valve element 21, the second channel 42 is connected to the third channel 43 through the first valve element 21, and the fifth channel 45 is connected to the sixth channel 46 through the second valve element 22.

[0026] At this time, the high-temperature and high-pressure working fluid at the outlet of compressor 200 flows through the indoor condenser 202 for condensation and heat dissipation, then flows into the first channel 41 through the first interface 411, and into the fourth channel 44 through the first valve element 21 and is located on the forward pressure side of the one-way valve 5. Under the action of the working fluid pressure, the one-way valve 5 is forward-biased and in the open state. The working fluid flows from the fourth channel 44 into the sixth channel 46 (at this time, the throttle valve 205 is closed). After being throttled by the second valve element 22, it becomes a low-temperature and low-pressure working fluid that flows into the fifth channel 45 and from the fifth interface 451 into the outdoor heat exchanger 204. After evaporation and heat absorption by the outdoor heat exchanger 204, it flows into the third channel 43 through the third interface 431 and into the second channel 42 through the first valve element 21. The working fluid located in the second channel 42 flows into the gas-liquid separation element 6 through the seventh channel 47. After gas-liquid separation, the gas phase working fluid flows into the eighth channel 48 and returns to the inlet of compressor 201 from the eighth interface 482 for recirculation.

[0027] Third working mode: The first valve element 21 is in the second working position, the second valve element 22 is in the closed state, the first channel 41 is connected to the fourth channel 41 through the first valve element 21, the second channel 42 is connected to the third channel 43 through the first valve element 21, and the fifth channel 45 is not connected to the sixth channel 46.

[0028] At this time, the high-temperature and high-pressure working fluid at the outlet of compressor 200 flows through the indoor condenser 202 for condensation and heat dissipation, then flows into the first channel 41 through the first interface 411, and into the fourth channel 44 through the first valve element 21 and is located on the forward pressure side of the one-way valve 5. Under the action of the working fluid pressure, the one-way valve 5 is forward-biased and in the open state. Since the second valve element 22 is closed, the working fluid flows out from the fourth interface 441, and after being throttled by the throttling valve 205 (at this time, the throttling valve 205 is open), it becomes a low-temperature and low-pressure working fluid and flows to the indoor evaporator 203. After evaporation and heat absorption by the indoor evaporator 203, it flows into the second channel 42 through the second interface 421. With the second valve element 22 closed, the working fluid located in the second channel 42 flows into the gas-liquid separation element 6 through the seventh channel 47. After gas-liquid separation, the gas phase working fluid flows into the eighth channel 48 and returns to the inlet of compressor 201 from the eighth interface 482 for recirculation.

[0029] The fluid control assembly 100 can achieve reversing communication between multiple channels through the first valve element 21, and can achieve straight-through and throttling between channels through the second valve element 22. In this way, when the fluid control assembly 100 is applied to the thermal management system, compared with the prior art which uses multiple switching valve elements and multiple throttling valve elements to achieve different working modes, it is beneficial to reduce the number of valve elements. In addition, the first valve element 21 and the second valve element 22 are respectively fixedly connected or limited to the valve block 1. Furthermore, the gas-liquid separation element 6 is also fixedly connected or limited to the valve block 1, and the gas-liquid separation element 6 and the valve element are set on both sides of the valve block 1 along the axial direction of the gas-liquid separation element 6. Compared with the prior art where each element is connected by a pipeline, it is beneficial to make the structure more compact.

For example, the directional definitions such as "front", "back", "left", "right", "up", and "down" are used. 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 this 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.
