[0021] The present application will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] join Figure 1 and Figure 2 Fluid control components can be applied to thermal management systems, such as vehicle thermal management systems, including those for new energy vehicles. The fluid control component 100 includes a drive component 1, a valve component 2, a connecting block 3, and a flow channel plate 4. The valve component 2 is connected to the connecting block 3. The drive component 1 can drive the valve component 2 to operate. The flow channel plate 4 is also connected to the connecting block 3. The fluid control component 100 has multiple channels. Under the action of the drive component 1, the valve component 2 can control the on / off state of two or more channels. Furthermore, when controlling the connection of two or more channels, the valve component 2 can either directly connect or throttle the connection of two or more channels. Direct connection is defined as the pressure of the working fluid before and after flowing through the valve component without change or tending to remain unchanged (e.g., pressure loss range <1%). Throttling connection is defined as the pressure of the working fluid before flowing through the valve component being greater than the pressure after flowing through the valve component. Connections are defined as fixed connections, limiting connections, detachable connections, sealed connections, or injection-molded connections.

[0023] join Figure 2 and Figure 3The number of valve components 2 can be multiple. In this embodiment, the valve components 2 are arranged linearly and include a first valve component 21, a second valve component 22, a third valve component 23, a fourth valve component 24, and a fifth valve component 25. Correspondingly, the connecting block 3 has mounting cavities, and the number of mounting cavities is the same as the number of valve components. In this embodiment, the mounting cavities can also be arranged linearly and include a first mounting cavity 31, a second mounting cavity 32, a third mounting cavity 33, a fourth mounting cavity 34, and a fifth mounting cavity 35. Some valve components are located in the mounting cavities and are connected to the connecting block 3. Specifically, in this embodiment, some of the first valve components 21 are located in the first mounting cavity 31, some of the second valve components 22 are located in the second mounting cavity 32, some of the third valve components 23 are located in the third mounting cavity 33, some of the fourth valve components 24 are located in the fourth mounting cavity 34, and some of the fifth valve components 25 are located in the fifth mounting cavity 35. The driving component 1 includes a driving mechanism, and there can be multiple driving mechanisms. In this embodiment, the driving mechanism includes a first driving mechanism 11, a second driving mechanism 12, a third driving mechanism 13, a fourth driving mechanism 14, and a fifth driving mechanism 15. The driving component 1 also includes a housing 16 and a circuit board 17. The housing 16 forms a receiving cavity 160 or at least a part of the receiving cavity 160. The driving mechanism and the circuit board 17 are located in the receiving cavity 160. The circuit board 17 is connected to the housing 16. In this embodiment, the circuit board 17 and the housing 16 are detachably connected by screws. Another portion of the valve component is located in the receiving cavity 160, and the drive mechanism is located on the outer periphery of the portion of the valve component located in the receiving cavity 160. The drive mechanism is electrically and / or signal-connected to the circuit board 17. Specifically, in this embodiment, the first drive mechanism 11 is sleeved on the outer periphery of the portion of the first valve component 21 located in the receiving cavity 160, and the first drive mechanism 11 is electrically and / or signal-connected to the circuit board 17; the second drive mechanism 12 is sleeved on the outer periphery of the portion of the second valve component 22 located in the receiving cavity 160, and the second drive mechanism 12 is electrically and / or signal-connected to the circuit board 17. / or signal connection; the third drive mechanism 13 is sleeved on the outer periphery of the portion of the third valve component 23 located in the receiving cavity 160, and the third drive mechanism 13 is electrically connected and / or signal connected to the circuit board 17; the fourth drive mechanism 14 is sleeved on the outer periphery of the fourth valve component 24 located in the receiving cavity 160, and the fourth drive mechanism 14 is electrically connected and / or signal connected to the circuit board 17; the fifth drive mechanism 15 is sleeved on the outer periphery of the fifth valve component 25 located in the receiving cavity 160, and the fifth drive mechanism 15 is electrically connected and / or signal connected to the circuit board 17.

[0024] See Figure 2 , Figure 4 as well as Figure 5Since the structures of the drive mechanisms are not significantly different, to avoid redundancy, the first drive mechanism 11 will be used as an example for explanation. The first drive mechanism 11 includes a coil assembly 111, a plastic-coated housing 112, and a pin 113. The coil assembly 111, pin 113, etc., are injection-molded inserts, integrally injection-molded to form the plastic-coated housing 112. The plastic-coated housing 112 encapsulates at least a portion of the coil assembly 111. One end of the pin 113 is located inside the plastic-coated housing 112 and is electrically connected and / or signal-connected to the coil assembly 111. The other end of the pin 113 is located outside the plastic-coated housing 112 and is electrically connected and / or signal-connected to the circuit board 17, thereby realizing the electrical connection and / or signal connection between the first drive mechanism 11 and the circuit board 17. It should be noted that, as other embodiments, the number of valve components and drive mechanisms can also be other, which can be determined according to the needs of actual applications.

[0025] See Figures 2 to 5 In the above structure, the drive mechanism of the drive component 1 is electrically and / or signal-connected to the same circuit board 17, and the valve component 2 is connected to the same connecting block 3. When there are multiple drive mechanisms and valve components, this is beneficial for the compact structure of the fluid control assembly 100 and saves material costs. However, this results in a longer length dimension for both the outer shell 16 and the connecting block 3. The length direction is defined as the linear distribution direction of the valve component 2. Since the outer shell 16 is made of plastic and the connecting block 3 is made of metal, their coefficients of linear expansion are different. As the fluid control assembly 100 operates in the thermal management system and temperature changes occur, their expansion and contraction along the length direction differ. Thus, with cumulative size changes, the expansion and contraction of the outer shell 16 along the length direction is greater than that of the connecting block 3. The circuit board 17 is connected to the outer shell 16 (e.g., detachably connected by screws in this embodiment), meaning the circuit board 17 follows the expansion and contraction of the outer shell 16. The drive mechanism is sleeved on the valve... The outer periphery of component 2 is affected by the extension and retraction of connecting block 3. This limits the drive mechanism via valve component 2, meaning the pins for electrical and / or signal connections between the drive mechanism and circuit board 17 are also limited by valve component 2. To ensure valve component 2 can better sense the excitation magnetic field generated by the drive mechanism, the inner peripheral wall of the drive mechanism is either flush with or has only a small gap with the outer peripheral wall of valve component 2. This causes a displacement deviation between circuit board 17 and the pins during the driven process, potentially leading to stress concentration at the connection point between the pins and circuit board 17 (e.g., fixed by welding in this embodiment), resulting in an unreliable connection and affecting the stability and reliability of the electrical and / or signal connections between the drive mechanism and circuit board 17. It should be noted that the definition of the length direction is merely for ease of understanding; furthermore, since the outer casing 16 is relatively short in other directions, the cumulative deviation caused by linear expansion is small and will not be considered further.

[0026] To solve the above problems, see [link to relevant documentation]. Figure 2 , Figures 4 to 6 Taking the first drive mechanism 11 as an example, the first drive mechanism 11 also includes a support block 114, which is connected to the pin 113. In this embodiment, the pin 113 is used as an injection molded insert, and the support block 114 is integrally injection molded. The pin 113 is disposed through the support block 114. Along the axial direction of the valve component 2, the support block 114 is disposed closer to the drive mechanism than the circuit board 17. In this embodiment, the support block 114 is close to the end of the pin 113 that is electrically connected and / or signal connected to the circuit board 17. The support block is connected to the outer shell 16. Specifically, taking the connection between the support block 114 of the first drive mechanism 11 and the outer shell 16 as an example, in this embodiment, the outer shell 16 also includes a protruding rib 161. Along the width direction of the outer shell 16, the protruding rib 161 protrudes from the inner wall surface 162 of the outer shell 16 in a direction away from the inner wall surface 162. The width direction is defined as a direction that is in the same horizontal plane as the length direction and perpendicular to the length direction. The protruding ribs 161 are symmetrically arranged, and the protruding ribs 161 form a limiting groove 1611. Along the height direction of the outer shell 16, the limiting groove 1611 is recessed inward from the upper end face of the protruding rib 161. The height direction is defined as a direction perpendicular to the horizontal plane containing the length and width directions. Along the height direction, the end face of the protruding rib 161 near the circuit board 17 is defined as the upper end face. Part of the support block 114 is located in the cavity formed by the limiting groove 1611. Along the length direction of the outer shell 16, the support block 114 is limited by the limiting groove 1611. By setting a support block and connecting it to the housing 16 (e.g., through a limiting groove 1611 in this embodiment), the support block can move with the extension and retraction of the housing 16. Along the axial direction of the valve component 2, the connection point between the support block and the pin is positioned closer to the drive mechanism than the connection point between the pin and the circuit board 17. This facilitates the transfer or partial transfer of stress from the connection point between the pin and the circuit board 17 to the injection-molded connection point between the support block and the pin, thereby reducing stress concentration at the connection point and improving the stability and reliability of the electrical and / or signal connections between the pin and the circuit board 17. Furthermore, in this embodiment, the support block 114 also abuts against the circuit board 17. This abutment provides support for the circuit board 17, further reducing stress concentration at the connection point and enhancing the strength of the circuit board 117.

[0027] join Figure 4 , Figures 6 to 8The drive mechanism is connected to the outer shell 16. Specifically, taking the connection between the first drive mechanism 11 and the outer shell 16 as an example, in this embodiment, the plastic-coated shell 112 of the first drive mechanism further includes a stepped portion 1121, which is a non-rotating body. Correspondingly, the outer shell 16 also includes an inner buckle 161, which protrudes from the inner wall surface 162 of the outer shell 16 in a direction away from the inner wall surface 162 along the width direction of the outer shell 16. The inner buckles 16 can be symmetrically arranged. Along the height direction of the outer shell 16, the stepped portion 1121 is located between the buckling portion of the inner buckle 161 and the bottom wall 163 of the outer shell 16. The buckling portion of the inner buckle 161 abuts against the stepped portion 1121, and the stepped portion 1121 abuts against the bottom wall 163 of the outer shell 16. The first drive mechanism 11 achieves a limiting connection with the outer shell 16 through the buckling cooperation of the stepped portion 1121 and the inner buckle 161. Setting the step portion 1121 as a non-rotating body and connecting the step portion 1121 to the housing 16 is beneficial in two ways: firstly, it facilitates the assembly and positioning of the drive mechanism; secondly, it allows the drive mechanism to follow the housing 16 along the length direction within the gap range with the valve component 2. To a certain extent, it also helps to reduce stress concentration at the connection point between the pin and the circuit board 17, thereby improving the stability and reliability of the electrical connection and / or signal connection between the pin and the circuit board 17.

[0028] See Figure 1 and Figure 9 The driving component 1 is also connected to the connecting block 3 through the outer shell 16. Specifically, in this embodiment, the outer shell 16 also includes an outer buckle 164. Along the height direction of the outer shell 16, the outer buckle 164 protrudes from the outer wall surface of the bottom wall 163 in a direction away from the outer wall surface. There are multiple outer buckles 164 and they can be arranged symmetrically. Correspondingly, the connecting block 3 also includes a buckle groove 36. Along the width direction of the outer shell 16, the buckle groove 36 is recessed inward from the side wall surface of the connecting block 3. When the driving component 1 is connected to the connecting block 3, the bottom wall 163 of the outer shell 16 abuts against the connecting block 3, and the buckling part of the outer buckle 164 abuts against the buckle groove 36. At least part of the buckling part of the outer buckle 164 is located in the cavity formed by the buckle groove 36. The drive component 1 is connected to the connecting block 3 by a snap-fit. On the one hand, this reduces the connection space, making the structure more compact and miniaturized. On the other hand, it allows the outer shell 16 to follow the direction of length through the snap-fit ​​groove 36 when it expands and contracts linearly. Compared with the outer shell 16 and the connecting block 3 being fixedly connected by screws or other means, this reduces the stress concentration caused by the linear expansion of the outer shell 16 and helps to improve the service life of the outer shell 16.

[0029] See Figure 2 and Figure 3The connecting block 3 also includes a protrusion 37. In this embodiment, the protrusion 37 protrudes from the bottom wall of the connecting block 3 in a direction away from the bottom wall along the axial direction of the mounting cavity. The wall of the connecting block 3 near the flow channel plate 4 along the axial direction of the mounting cavity is defined as the bottom wall. There can be multiple protrusions 37. In this embodiment, the protrusions 37 include a first protrusion 371, a second protrusion 372, a third protrusion 373, a fourth protrusion 374, a fifth protrusion 375, a sixth protrusion 376, and a seventh protrusion 377. The protrusions 37 can be arranged linearly. Each protrusion 37 has a communication opening. The connecting block 3 also has a first channel 38 and a second channel 39. The first channel 38 includes a first interface 381. For a single component of the connecting block 3, the first mounting cavity 31 is connected through the first channel 38. The first mounting cavity 32 connects the first interface 381 and the first protrusion 371 through the first channel 38, the second mounting cavity 33 connects the first interface 381 and the second protrusion 372 through the first channel 38, the third mounting cavity 33 connects the third protrusion 373 and the fourth protrusion 374 through the first channel 39, the fourth mounting cavity 34 connects the fifth protrusion 375 and the sixth protrusion 376 through the second channel 39, and the fifth mounting cavity 35 connects the sixth protrusion 376 and the seventh protrusion 377 through the second channel 39.

[0030] See Figure 2 , Figure 3 , Figure 10 as well as Figure 11The flow channel plate 4 has a channel and includes a first plate 41 and a second plate 42. The first plate 41 and / or the second plate 42 form grooves or holes for the channel of the flow channel plate 4. The first plate 41 and the second plate 42 cooperate to form a complete channel of the flow channel plate 4. In this embodiment, the first plate 41 and / or the second plate 42 are formed by stamping sheet metal. The first plate 41 includes a first wall 411. Along a direction perpendicular to the first wall 411, the first plate 41 is stamped to form half of the channel of the flow channel plate 4 away from the first wall 411. The second plate 42 includes a second wall 421. Along a direction perpendicular to the second wall 421, the second plate 42 is stamped to form the other half of the channel of the flow channel plate 4 away from the second wall 421. The first wall 411 and the second wall 421 are fitted together and connected. For example, in this embodiment, the first wall 411 and the second wall 421 are fixedly connected by welding. The flow channel plate 4 has a mounting cavity 43, which is formed by a portion of the channel in the flow channel plate 4. At least a portion of the protrusion 37 of the connecting block 3 is located in the mounting cavity 43. The communication port of the protrusion 37 communicates with the channel forming the mounting cavity 43. The protrusion 37 is connected to the flow channel plate 4, thereby realizing the connection between the connecting block 3 and the flow channel plate 4. In this embodiment, the protrusion 37 and the flow channel plate 4 are fixedly connected by welding. Along the direction of the central axis of the valve component 2, the connecting block 3 is disposed closer to the valve component 2 than the flow channel plate 4. The central axis of the valve component 2 is parallel or tends to be parallel to the first wall and / or the second wall. The flow channel plate 4 abuts against or has a gap with the connecting block 3. The number of mounting cavities 43 is the same as the number of protrusions 37. Specifically, in this embodiment, the mounting cavities 43 include a first mounting cavity 431, a second mounting cavity 432, a third mounting cavity 433, a fourth mounting cavity 434, a fifth mounting cavity 435, a sixth mounting cavity 436, and a seventh mounting cavity 437. At least a portion of the first protrusions 371 are located in the first mounting cavity 431, at least a portion of the second protrusions 372 are located in the second mounting cavity 432, at least a portion of the third protrusions 373 are located in the third mounting cavity 433, at least a portion of the fourth protrusions 374 are located in the fourth mounting cavity 434, at least a portion of the fifth protrusions 375 are located in the fifth mounting cavity 435, at least a portion of the sixth protrusions 376 are located in the sixth mounting cavity 436, and at least a portion of the seventh protrusions 377 are located in the seventh mounting cavity 437. The flow channel plate 4 is formed by stamping a first plate 41 and / or a second plate 42 from sheet metal, and the first plate 41 and the second plate 42 cooperate to form the channel plate 4. Compared with the related technology where the channel is integrally formed in the connecting block by machining, this method simplifies the channel processing and reduces the weight of the fluid control assembly 100. Of course, as other embodiments, the flow channel plate may also include, but is not limited to, a third plate, such as a second plate located between the first plate and the third plate, where the first plate and the second plate cooperate to form part of the channel plate, and the second plate and the third plate cooperate to form another part of the channel plate.Alternatively, as another embodiment, it is readily apparent that the protrusion may also be formed on the flow channel plate, with the communication port of the protrusion forming part of a portion of the channel in the flow channel plate. The connecting block has a mounting cavity, which is recessed inward from the bottom wall of the connecting block along the axial direction of the mounting cavity. The mounting cavity communicates with the mounting cavity, with regard to the connecting block alone. At least a portion of the protrusion is located in the mounting cavity, the flow channel plate is connected to the connecting block via the protrusion, and the mounting cavity communicates with the channel forming the communication port via the communication port.

[0031] See Figure 1 and Figure 2 In this embodiment, the channels of the flow channel plate 4 include a third channel 400, a fourth channel 401, a fifth channel 402, a sixth channel 403, a seventh channel 404, and an eighth channel 405. The third channel 400 forms a first mounting cavity 431, and the communication port of the first protrusion 371 is connected to the third channel 400. In this way, the first valve component 21 can connect or disconnect the first channel 38 and the third channel 400, and when connected, it can throttle the connection or directly connect the first channel 38 and the third channel 400. Similarly, the fourth channel 401 forms a second mounting cavity 432, and the communication port of the second protrusion 372 is connected to the fourth channel 401. The second valve component 22 can connect or not connect the first channel 38 and the fourth channel 401, and when connected, it can throttle the connection or directly connect the first channel 38 and the fourth channel 401. The fourth channel 401 also forms a third mounting cavity 433, and the communication port of the third protrusion 373 is connected to the fourth channel 401. The fifth channel 402 forms a fourth mounting cavity 434. The protrusion 374 has a connecting port that connects to the fifth channel 402, allowing the third valve component 23 to connect to or disconnect the fourth channel 401 and the fifth channel 402. When connected, it can either throttle or directly connect the fourth channel 401 and the fifth channel 402. The sixth channel 403 has a fifth mounting cavity 435, and the connecting port of the fifth protrusion 375 connects to the sixth channel 403. The seventh channel 404 has a sixth mounting cavity 436, and the connecting port of the sixth protrusion 376 connects to the seventh channel 404. The fourth valve component 24 can connect to or not connect to the sixth channel 403 and the seventh channel 404 through the second channel 39, and when connected, it throttles the connection between the sixth channel 403 and the seventh channel 404; the eighth channel 405 forms a seventh mounting cavity 437, and the communication port of the seventh protrusion 377 is connected to the eighth channel 405; the fifth valve component 25 can connect to or not connect to the seventh channel 404 and the eighth channel 405 through the second channel 39, and when connected, it throttles the connection between the seventh channel 404 and the eighth channel 405.

[0032] See Figure 1 and Figure 2In this embodiment, the channels of the flow channel plate 4 also include a ninth channel 406, a tenth channel 407, an eleventh channel 408, a twelfth channel 409, and a thirteenth channel 410. As for the flow channel plate 4 alone, the ninth channel 406 is connected to the fifth channel 402, the tenth channel 407 is connected to the ninth channel 406, the eleventh channel 408 is connected to the seventh channel 404, the twelfth channel 409 is connected to the eighth channel 405, and the thirteenth channel 410 is connected to the twelfth channel 409. The fluid control assembly 100 also includes a check valve 6, which has the function of forward conduction and reverse cut-off under the action of fluid pressure difference. In this embodiment, the check valve 6 includes a first check valve 61, a second check valve 62, and a third check valve 63. The first check valve 61 is located in the ninth channel 406. Along the axial direction of the first check valve 61, the valve port of the first check valve 61 is set further away from the processing opening 4061 of the ninth channel 406 than the connection port between the ninth channel 406 and the tenth channel 407. The processing opening 4061 is sealed with a plug 5. The processing opening 4061 is mainly set for the convenient installation of the first check valve 4061. The first check valve 61 enables forward conduction from the tenth channel 407 to the ninth channel 406. Similarly, the second check valve 62 is located in the twelfth channel. Channel 409, along the axial direction of the second check valve 62, has its valve port further away from the machining opening of the twelfth channel 409 than the connection port between the twelfth channel 409 and the eighth channel 405. The machining opening of the twelfth channel 409 is also sealed by a plug 5. The second check valve 62 enables forward flow from the eighth channel 405 to the twelfth channel 409. The third check valve 63 is located in the thirteenth channel 410. Along the axial direction of the third check valve 63, its valve port is closer to the machining opening of the thirteenth channel 410 than the connection port between the thirteenth channel 410 and the twelfth channel 409. The machining opening of the thirteenth channel 410 is also sealed by a plug 5. The third check valve 63 enables forward flow from the thirteenth channel 410 to the twelfth channel 409.

[0033] See Figure 2In this embodiment, at least a portion of the tenth channel 407 is positioned close to the eleventh channel 408. Specifically, the tenth channel 407 includes a first channel segment 4071, and correspondingly, the eleventh channel 408 includes a second channel segment 4081 formed around the first channel segment 4071. The first channel segment 4071 is positioned close to the second channel segment 4081, allowing the working fluid within the first channel segment 4071 to exchange heat with the working fluid within the second channel segment 4081. In this embodiment, the first channel segment 4071 is approximately U-shaped, and correspondingly, the second channel segment 4081 formed around the first channel segment 4071 is also U-shaped. Positioning the first channel segment 4071 and the second channel segment 4081 as U-shaped increases the heat exchange area and makes the channel structure more compact. Of course, in other embodiments, the first channel segment 4071 and the second channel segment 4081 can also have other shapes. Positioning the first channel segment 4071 close to the second channel segment 4081 increases beneficial heat exchange between the channels, thus contributing to energy savings when the fluid control component 100 is applied to the system. Of course, to avoid harmful heat exchange between certain channels, some channels are also insulated. For example, in this embodiment, the flow channel plate 4 also includes a first groove 44, which extends through the flow channel plate 4 and is disposed along the axial direction of the valve component 2. The third channel 400 and the fourth channel 401 are located on one side of the first groove 44, and at least a portion of the fifth channel 402 and at least a portion of the ninth channel 406 are located on the opposite side of the first groove 44. Referring to the figure, in this embodiment, the flow channel plate 4 also includes a second groove 45, which also extends through the flow channel plate 4. The second groove 45 is mainly used to reduce the weight of the flow channel plate 4.

[0034] See Figure 1 and Figure 2The fluid control component 100 has interfaces that allow it to connect and communicate with other components in the thermal management system. In this embodiment, in addition to the first interface 381 mentioned above, the interfaces also include a second interface 462, a third interface 463, a fourth interface 464, a fifth interface 465, a sixth interface 466, a seventh interface 467, an eighth interface 468, a ninth interface 469, a tenth interface 470, an eleventh interface 471, and a twelfth interface 472. The second interface 462 is connected to the third channel 400. The third interface 463 is connected to the fourth channel 401, the fourth interface 464 is connected to the fifth channel 402, the fifth interface 465 is connected to the ninth channel 406, the sixth interface 466 is connected to the sixth channel 403, the seventh interface 467 is connected to the eighth channel 405, the eighth interface 468 is connected to the tenth channel 407, the ninth interface 469 is connected to the eleventh channel 408, the tenth interface 470 is connected to the thirteenth channel 410, the eleventh interface 471 is connected to the twelfth channel 409, and the twelfth interface 472 is connected to the seventh channel 404. Thus, the first valve component 21 can connect or disconnect the first interface 381 and the second interface 462, and when connected, it can directly connect or throttle the connection between the first interface 381 and the second interface 462; the second valve component 22 can connect or disconnect the first interface 381 and the third interface 463, and when connected, it can directly connect or throttle the connection between the first interface 381 and the third interface 463; the third valve component 23 can connect or disconnect the third interface 463 and the fourth interface 464, and when connected, it can directly connect or throttle the connection between the third interface 463 and the fourth interface 464, with the fourth interface 464 connected to the fifth interface 465; the fourth valve component 24 can... The system can connect or disconnect the twelfth interface 472 and the sixth interface 466, and throttles the connection between the twelfth interface 472 and the sixth interface 466 when connected; the fifth valve component 25 can connect or disconnect the twelfth interface 472 and the seventh interface 467, and throttles the connection between the twelfth interface 472 and the seventh interface 467 when connected; the first one-way valve 61 allows the eighth interface 468 to pass through the fifth interface 465 in a forward direction; the ninth interface 469 is connected to the twelfth interface 472; the second one-way valve 62 allows the seventh interface 467 to pass through the eleventh interface 471 in a forward direction; the third one-way valve 63 allows the tenth interface 470 to pass through the eleventh interface 471 in a forward direction. In this embodiment, the second interface 462 to the twelfth interface 472 are all located on the same side of the flow channel plate 4, and the first interface 381 is located on one side of the connecting block 3, which facilitates the docking of the interfaces with other components in the thermal management system. Of course, in other embodiments, the interfaces can also be located on different sides of the flow channel plate 4.

[0035] See Figure 1 , Figure 2 as well as Figure 12This is one embodiment of the fluid control component 100 applied to a thermal management system. In this embodiment, the thermal management system includes a compressor 201, a liquid receiver 202, an outdoor heat exchanger 203, a condenser 204, an evaporator 205, and an expansion valve 206. The outlet of the compressor 201 is connected to the first interface 381, the inlet of the compressor 201 is connected to the fifth interface 465, the inlet of the liquid receiver 202 is connected to the eleventh interface 471, and the outlet of the liquid receiver 202 is connected to the twelfth interface 472. The outdoor heat exchanger 203 is connected to the third interface 463 at one port and to the seventh interface 467 at the other port. The condenser 204 has its inlet connected to the second interface 462 and its outlet connected to the tenth interface 470. The evaporator 205 has its outlet connected to the eighth interface 468 and its inlet connected to the ninth interface 469 via an expansion valve 206, which throttles the flow of the working fluid. In this embodiment, the thermal management system also includes a heat exchange element 207, which has a first flow channel and a second flow channel that are not directly connected. The heat exchange element 207 can be involved in heat exchange between the working fluid (such as refrigerant) in the first flow channel and the working fluid (such as coolant) in the second flow channel. The inlet of the first flow channel of the heat exchange element 207 is connected to the sixth interface 466, and the outlet of the first flow channel is connected to the fourth interface 464.

[0036] In this embodiment, the fluid control component 100 is applied to the thermal management system, including but not limited to two operating modes:

[0037] See Figure 1 , Figure 2 as well as Figure 12 ,like Figure 12 As shown by the solid line, the first working mode is as follows: the first valve component 21, the third valve component 23, and the fifth valve component 25 are closed, the second valve component 22 and the fourth valve component 24 are open, the second valve component 22 is directly connected to the first interface 381 and the third interface 463, and the fourth valve component 24 is throttled to connect the twelfth interface 472 and the sixth interface 466. At this time, the expansion valve 206 is open.

[0038] The specific workflow is as follows: The high-temperature and high-pressure gaseous working fluid (such as refrigerant) at the outlet side of compressor 201 enters the first channel 38 of the fluid control component from the first interface 381, and flows to the outdoor heat exchanger 203 from the third interface 463 through the second valve component 22. After condensation and heat dissipation in the outdoor heat exchanger 203, it becomes a gas-liquid two-phase working fluid and flows into the eighth channel 405 of the fluid control component from the seventh interface 467. Under the forward conduction of the second one-way valve 62, it flows to the liquid receiver 202 through the eleventh interface 371. After gas-liquid separation in device 202, the liquid working fluid flows from the twelfth port 472 into the seventh channel 404 of the fluid control assembly. A portion flows through the eleventh channel 408 from the ninth port 469 to the expansion valve 206. After being throttled and expanded by the expansion valve 206, it becomes a low-temperature, low-pressure gas-liquid two-phase working fluid that flows to the evaporator 206. After evaporation and heat absorption in the evaporator 206, it becomes a gas-phase saturated working fluid that flows from the eighth port 468 into the tenth channel 407 of the fluid control assembly. The lower-temperature working fluid located in the tenth channel 407 can react with... The higher-temperature working fluid located in the eleventh channel 408 undergoes beneficial heat exchange. Specifically, the working fluid in the first channel section 4071 of the tenth channel 407 and the working fluid in the second channel section 4081 of the eleventh channel 408 undergo beneficial heat exchange, thus ensuring that the working fluid in the tenth channel 407 is a saturated gas phase working fluid. The saturated gas phase working fluid in the tenth channel 407 flows to the ninth channel 406 under the forward conduction of the first one-way valve 61, and flows to the inlet of the compressor 201 for recirculation through the fifth interface 465. Another part of the liquid phase working fluid located in the seventh channel 404 becomes a low-temperature, low-pressure gas-liquid two-phase working fluid after being throttled by the fourth valve component 24 and flows into the sixth channel 403, and flows to the first flow channel of the heat exchange element 207 from the sixth interface 466. After exchanging heat with the working fluid in the second flow channel, it becomes a gas phase saturated working fluid and flows into the fifth channel 402 of the fluid control component from the fourth interface 464, and also flows to the inlet of the compressor 201 for recirculation through the fifth interface 465.

[0039] See Figure 1 , Figure 2 as well as Figure 13 ,like Figure 13 As shown in the figure, this is the second working mode: the first valve component 21, the third valve component 23, the fourth valve component 24, and the fifth valve component 24 are open, the second valve component 22 is closed, the first valve component 21 is directly connected to the first interface 381 and the second interface 462, the third valve component 23 is directly connected to the third interface 463 and the fifth interface 465, the fourth valve component 24 is throttled to the twelfth interface 472 and the sixth interface 466, and the fifth valve component 25 is throttled to the twelfth interface 472 and the seventh interface 467. At this time, the expansion valve 206 is closed.

[0040] The specific workflow is as follows: The high-temperature and high-pressure gaseous working fluid from the outlet side of compressor 201 enters the first channel 38 of the fluid control component from the first interface 381, and flows to the condenser 204 from the second interface 462 through the first valve component 21. After being condensed and cooled by the condenser 204, it becomes a two-phase gas-liquid working fluid that flows from the tenth interface 470 to the thirteenth channel 410 of the fluid control component. Under the forward conduction of the third check valve 62, it flows into the twelfth channel 409 and from the eleventh interface 471 to the liquid receiver 202. At this time, the second check valve 62 is in the reverse cut-off state. After gas-liquid separation in the liquid receiver 202, the liquid working fluid flows from the twelfth interface 472 into the seventh channel 404 of the fluid control component. Since the expansion valve 206 is closed, part of the liquid working fluid in the seventh channel 404 becomes a low-temperature and low-pressure fluid after being throttled by the fifth valve component 25. The gas-liquid two-phase working fluid flows from the seventh port 467 to the outdoor heat exchanger 203. After evaporation and heat absorption in the outdoor heat exchanger 203, it becomes a gas-phase saturated working fluid that flows from the third port 463 to the fourth channel 401 of the fluid control component. It then flows into the fifth channel 402 through the third valve component 23 and into the inlet of the compressor 201 through the fifth port 465 for recirculation. Another part of the liquid working fluid in the seventh channel 404 becomes a low-temperature, low-pressure gas-liquid two-phase working fluid after being throttled by the fourth valve component 24. It flows into the sixth channel 403 and from the sixth port 466 to the first flow channel of the heat exchange element 207. After heat exchange and heat absorption with the working fluid in the second flow channel, it becomes a gas-phase saturated working fluid that flows into the fifth channel 402 of the fluid control component through the fourth port 464 and into the inlet of the compressor 201 through the fifth port 465 for recirculation.
