[0020] The present application will be further described below with reference to the accompanying drawings and specific embodiments:

[0021] See Figures 1 to 3 The valve device can be applied to a vehicle thermal management system, including a new energy vehicle thermal management system. The valve device 100 includes a control component 1, a first valve component 2, a second valve component 3, and a valve body component 4. The first valve component 2 includes a first valve stem 21 and a first valve core 22. The first valve core 22 is located in the first valve body cavity 40 formed by the valve body component 4. One end of the first valve stem 21 is driveably connected to the control component 1, and the other end of the first valve stem 21 is driveably connected to the first valve core 22. The control component 1 is connected to the valve body component 4 and can output torque to the first valve stem 21, causing the first valve core 22 to rotate. The control component 1 can be electrically and / or signal connected to the outside. The second valve component 3 is partially movably installed inside the valve body component 4. In this embodiment, the first valve core 22 is spherical. The control component 1 may include a gear reduction mechanism 11, which drives the first valve stem 21. The gear reduction mechanism 11 is beneficial for increasing the output torque of the control component 1. Of course, as other embodiments, the first valve core 22 can also be in other shapes, such as cylindrical, frustum, etc., and the control component 1 may not include the gear reduction mechanism 11.

[0022] See Figures 4 to 6 The valve body component 4 includes a valve body 41 and an interface portion 42. The interface portion 42 is fixedly connected to the valve body 41. In this embodiment, the interface portion 42 and the valve body 41 are fixedly connected by screws. Of course, in other embodiments, the interface portion 42 and the valve body 41 can also be fixedly connected by welding, gluing, snap-fitting, or other methods known to those skilled in the art. The valve body 41 has a first cavity 411 and a second cavity 412. The interface portion 42 includes a plate portion 421, a first connecting pipe 422, and a second connecting pipe 423. The first connecting pipe 422 and the second connecting pipe 423 protrude from the plate portion 421 and are located on the same side of the plate portion 421. See also Figure 4At least a portion of the first connecting pipe 422 is located in the first cavity 411, and at least a portion of the second connecting pipe 423 is located in the second cavity 412. The first connecting pipe 422 and the first cavity 411 are assembled to form the first valve body cavity 40, and the second connecting pipe 423 and the second cavity 412 are assembled to form the second valve body cavity 43. The plate portion 421 can abut against the surface of the valve body 41. The plate portion 421 is provided with a through hole, and the valve body 41 is provided with a screw hole. The screw passes through the through hole and is threaded into the screw hole on the valve body 41 to achieve a fixed connection between the interface portion 42 and the valve body 41. Furthermore, a sealing setting can be provided between the interface portion 42 and the valve body 41 to prevent the working medium from leaking from the assembly gap between the interface portion 42 and the valve body 41. Specifically, see Figure 6 The first connector 422 includes a first recessed portion 4221, and the second connector 423 includes a second recessed portion 4231. See also... Figure 4 The valve body component 4 also includes a first seal 424 and a second seal 425. When the interface portion 42 is assembled with the valve body 41, a portion of the first seal 424 is located in the first groove formed by the first groove portion 4221. The first seal 424 is pressed between the first groove portion 4221 and the valve body 41, and the first seal 424 is in a sealed and pressed state. Similarly, a portion of the second seal 425 is located in the second groove formed by the second groove portion 4231. The second seal 425 is pressed between the second groove portion 4231 and the valve body 41, and the second seal 425 is in a sealed and pressed state.

[0023] See Figure 4 The valve body component 4 also includes a first channel 44, a second channel 45, a third channel 46, a fourth channel 47, and a fifth channel 48. The second channel 45 and the fourth channel 47 are located at the interface portion 42, while the first channel 44, the third channel 46, and the fifth channel 48 are located at the valve body 41. Regarding the valve body component 4, the first valve body cavity 40 connects the first channel 44 and the second channel 45, and also connects the first channel 44 and the third channel 46. The second valve body cavity 43 connects the fourth channel 47 and the fifth channel 48, and the third channel 46 connects with the fifth channel 48. In this embodiment, by setting at least a portion of the axial direction of the first channel 44 perpendicular to the axial direction of the second channel 45, and the axial direction of the first channel 44 perpendicular to the axial direction of the third channel 46, with the central axis of the second channel 45 and the central axis of the third channel 46 on the same straight line, and the fourth channel 47 parallel to the second channel 45, it is beneficial to reduce the length of the channels and the connection distance between the channels, thus facilitating the miniaturization of the valve body component 4. Of course, as another implementation, the channel length can be further reduced and the valve body assembly 4 can be miniaturized by setting at least a portion of the fifth channel 48 to be perpendicular to the axis of the third channel 46 and at least a portion of the fifth channel 48 to be perpendicular to the axis of the fourth channel 47.

[0024] See Figure 1 , Figure 2 and Figure 4 In this embodiment, the valve body 41 further includes a first protrusion 413 and a second protrusion 414, which are located on the same side of the valve body 41. A first channel 44 forms a first port 441 on the free end face of the first protrusion 413, a second channel 45 forms a second port 451 on the surface of the plate portion 421, and a fourth channel 47 forms a third port 471 on the surface of the plate portion 421. The second port 451 and the third port 471 are formed on the same surface of the plate portion 421, which facilitates the connection of the plate portion 421 with other components. A fifth channel 48 forms a fourth port 481 on the free end face of the second protrusion 414. By providing the first protrusion 413 and the second protrusion 414, the valve body 41 is advantageous when the valve device 100 is connected to other component pipelines, allowing the first protrusion 413 and / or the second protrusion 414 to extend into the interior of other components, which is beneficial for the integration, limiting, and positioning of the valve device 100 with other components. Of course, as in other embodiments, the valve body 41 may also exclude the first protrusion 413 and the second protrusion 414, that is, the first port 441 of the first channel 44 and the fourth port 481 of the fifth channel 48 are respectively formed on the surface of the valve body 41.

[0025] See Figure 3 The first valve core 22 is located in the first valve body cavity 40. The first valve component 2 also includes a valve core seat 23, which is located on both sides of the first valve core 22. The valve core seat 23 is provided with an arc-shaped surface that mates with the outer surface of the first valve core 22. At least part of the arc-shaped surface of the valve core seat 23 can be fitted to the surface of the first valve core 22. The first valve core 22 can slide with the valve core seat 23. The valve core seat 23 supports and seals the first valve core 22. Furthermore, the valve core seat 23 can be sealed with the first connecting pipe 422 and / or with the valve body 41, which helps to prevent the working medium from leaking from the assembly gap between the valve core seat 23 and the valve body 41 and / or between the valve core seat 23 and the first connecting pipe 422. The first valve core 22 includes a connecting hole 221 that penetrates through the first valve core 22. In this embodiment, the connecting hole 221 is approximately L-shaped. Of course, in other embodiments, the connecting hole 221 can also be other shapes. By rotating the first valve core 22, the connecting hole 221 can connect the first channel 44 and the second channel 45, or connect the first channel 44 and the third channel 46. That is, the valve device 100 can selectively connect the first channel 44 with the second channel 45 or the third channel 46 by rotating the first valve core 22. It should be noted that by rotating the first valve core 22, the first channel 44 can also be de-connected to both the second channel 45 and the third channel 46, that is, the first valve component 2 is in a closed state at this time.

[0026] See Figures 7 to 9 The second valve component 3 includes a second valve stem 31, a second valve core 32, a valve seat 33, an elastic element 34, a retaining ring 35, and a snap ring 36. The valve seat 33 has a receiving cavity 331, a channel 332, and a communicating cavity 333. For the valve seat 33 as a single component, the channel 332 communicates with the receiving cavity 331, and the communicating cavity 333 communicates with the receiving cavity 331. (See [reference]). Figure 7 and Figure 8 At least a portion of the second valve core 32 can be located in the receiving cavity 331. One end of the second valve stem 31 is fixedly connected to the second valve core 32, and the other end of the second valve stem 31 protrudes through the channel 332. The elastic element 34 is located on the outer periphery of the second valve stem 31, and the retaining ring 35 is located on the outer periphery of the second valve stem 31. The elastic element 34 is located between the retaining ring 35 and the valve seat 33. The elastic element 34 is in an elastically compressed state. The second valve stem 31 includes a third groove portion 311. The third groove portion 311 is provided near the free end of the second valve stem 31. A portion of the retaining spring 36 is located in the third cavity formed by the third groove portion 311. The retaining spring 36 is limited by the stepped surfaces at both ends of the third groove portion 311. Thus, under the elastic force of the elastic element 34, one end of the elastic element 34 abuts against the valve seat 33, and the other end of the elastic element 34 abuts against one end face of the retaining ring 35. The other end face of the retaining ring 35 abuts against the retaining spring 36, and the retaining spring 36 abuts against the stepped surface of the third groove portion 311.

[0027] See Figure 3 , Figure 5 as well as Figure 8 The second valve component 3 is partially movably installed inside the valve body component 4. Specifically, part of the second valve component 3 is located in the second valve body cavity 43, and another part of the second valve component 3 is located in the fourth channel 47. More specifically, the retaining ring 35, the snap ring 36, and at least part of the elastic element 34 are located in the fourth channel 47, and at least part of the valve seat 33 is located in the second valve body cavity 43. The valve body 41 also includes a first step portion 415, which is located on the circumferential wall forming the second cavity 412. The valve seat 33 can be limited by the first step portion 415 and the free end of the second connecting pipe 423. Furthermore, a sealing arrangement can be made between the valve seat 33 and the valve body 41. Specifically, the valve seat 33 is located in the second valve body cavity 43. Figure 8 and Figure 9 The valve seat 33 also includes a fourth recess 334, and the second valve component 3 also includes a third seal 37. A portion of the third seal 37 is located in the fourth cavity formed by the fourth recess 334, and the third seal 37 maintains a certain tension on the valve seat 33. See also Figure 3 When the valve seat 33 is located in the second valve body cavity 43, the third seal 37 is pressed between the fourth groove 334 and the valve body 41, and the third seal 37 is in a sealed and pressed state. See also Figure 3 and Figure 8The second valve core 32 is located in the second valve body cavity 43. As the second valve core 32 moves, at least a portion of the second valve core 32 can be located in the receiving cavity 331 of the valve seat 33. (See also...) Figure 8 The second valve core 32 includes a fifth groove portion 321, and the second valve component 3 also includes a fourth seal 38. A portion of the fourth seal 38 is located in the fifth cavity formed by the fifth groove portion 321, and the fourth seal 38 maintains a certain tension on the second valve core 32. See also Figure 3 When the working medium acts on the first end face 322 of the second valve core 32, under the pressure of the working medium, the second valve core 32 moves closer to the fourth channel 47 along the axial direction of the fourth channel 47. As the second valve core 32 moves, it can abut against the circumferential wall forming the receiving cavity 331. The fourth seal 38 can be pressed between the fifth groove 321 and the valve seat 33. The fourth seal 38 is in a sealed and pressed state. At this time, the second valve component 3 is closed, and the working medium cannot flow from the fifth channel 48 to the fourth channel 47, or in other words, the fourth channel 47 and the fifth channel 48 are not connected at this time. When the working medium flows in from the third port 471 of the fourth channel 47, the working medium can act on the second end face 323 of the second valve core 32 through the connecting cavity 333 of the valve seat 33. Under the pressure of the working medium, the second valve core 32 moves away from the fourth channel 47 along the axial direction of the fourth channel 47. As the second valve core 32 moves, a fitting gap can be formed between the second valve core 32 and the circumferential wall forming the receiving cavity 331. The working medium can flow to the fifth channel 48 through this fitting gap. With the continuous movement of the second valve core 32, when the second valve core 32 is not located in the receiving cavity 331, the working medium can also flow to the fifth channel 48 in a large flow rate after passing through the connecting cavity 333 and the receiving cavity 331. At this time, the second valve component 3 opens, and the fourth channel 47 and the fifth channel 48 are connected. As can be seen from the above, the second valve component 3, as a one-way valve, has a one-way conduction function.

[0028] See Figure 2 and Figure 10In this embodiment, the valve device 100 further includes a temperature sensor 5, which includes a connecting part 51, a sensing part 52, and a housing 53. The valve body 41 also includes a first mounting part 416, which forms a first mounting cavity 417. The first mounting cavity 417 communicates with the first channel 44. In this embodiment, the surface of the first mounting part 416 has an internal thread section, and the surface of the housing 53 of the temperature sensor 5 has an external thread section. Part of the temperature sensor 5 is located in the first mounting cavity 417, and the sensing part 52 is located in the first mounting cavity 417 or in the first channel 44. The temperature sensor 5 is threadedly engaged with the first mounting part 416, so that the temperature sensor 5 is fixedly connected to the valve body 41. Of course, as in other embodiments, the temperature sensor 5 and the valve body 41 can also be connected by other means such as tightening with a nut, gluing, or limiting. Temperature sensor 51 is electrically and / or signal-connected to the outside world via connection part 51. Specifically, connection part 51 includes pin 511, and sensing part 52 can sense the temperature of the working medium and convert it into an electrical signal, achieving electrical and / or signal connection with the outside world through pin 511. Of course, as another embodiment, temperature sensor 51 may not include connection part 51, that is, temperature sensor 51 is first electrically and / or signal-connected to control component 1, and then electrically and / or signal-connected to the outside world through control component 1. Temperature sensor 51 is provided to measure the temperature of the working medium in the first channel 44, determine whether the working medium temperature reaches the subcooling requirement required by the system, thereby enabling the valve device to switch different flow paths. Of course, as another embodiment, valve device 100 may not include temperature sensor 5, or temperature sensor 5 may be located in other positions in the system pipeline, that is, temperature sensor 5 is not integrated on valve device 100, and valve device 100 directly receives external control commands through control component 1 to switch flow paths.

[0029] See Figure 1 , Figure 2 as well as Figure 11The valve device 100 can be applied to a thermal management assembly, which includes the valve device 100, a liquid receiver 200, and an intermediate heat exchanger 400. The first port 441 of the valve device is connected to the outlet of the liquid receiver 200, the second port 451 serves as an outlet for connection to other devices in the thermal management system, the third port 471 serves as an inlet for connection to other devices in the thermal management system, and the fourth port 481 is connected to the inlet of the intermediate heat exchanger 400. In this embodiment, the second port 451 is connected to the inlet of the subcooler 300 in the thermal management system, and the third port 481 is connected to the outlet of the subcooler 300. Thus, when the thermal management system has a high demand for the subcooling of the working medium, or when the temperature of the working medium in the first channel 44 measured by the temperature sensor 5 does not meet the required subcooling of the system, the flow direction of the working medium in the thermal management component is as shown by the solid arrow in the figure. After the working medium comes out of the liquid reservoir 200, it enters the first channel 44 from the first port 441. The first valve core 22 is rotated, so that the working medium flows through the connecting hole 221 of the first valve core 22 to the second channel 45. The working medium in the second channel 45 flows through the second port 451 to the inlet of the subcooler 300. After the working medium is condensed and dissipated by the subcooler 300, the working medium flows back from the outlet of the subcooler 300 through the third port 471 to the fourth channel 47 of the valve device. The working medium in the fourth channel 47 pushes the second end face 323 of the second valve core 32, so that the second valve component 3 opens. The working medium flows through the second valve component 3 to the fifth channel 48, and flows from the fourth port 481 to the subsequent intermediate heat exchanger 400.

[0030] See Figure 1 , Figure 2 as well as Figure 12 When the thermal management system does not require a high degree of subcooling of the working medium, or when the temperature of the working medium in the first channel 44 measured by the temperature sensor 5 reaches the required degree of subcooling of the system, the flow direction of the working medium in the thermal management component is as shown by the dashed arrow in the figure. After the working medium comes out of the reservoir 200, it enters the first channel 44 from the first port 441. The first valve core 22 is rotated so that the working medium flows through the connecting hole 221 of the first valve core 22 to the third channel 46. The third channel 46 is connected to the fifth channel 48. The working medium flows from the third channel 46 into the fifth channel 48. The working medium in the fifth channel 48 pushes the first end face 322 of the second valve core 32, causing the second valve component 3 to close. That is, the working medium cannot enter the fourth channel 47 through the second valve component 3. The working medium in the fifth channel 48 flows directly to the subsequent intermediate heat exchanger 400 through the fourth port 481. That is, the working medium does not pass through the condensation and heat dissipation of the subcooler 300 and flows directly to the subsequent intermediate heat exchanger 400.

[0031] In the thermal management component, the valve device 100 can switch different flow paths according to the subcooling requirements of the thermal management system for the working medium through the first valve component 2, allowing the working medium to selectively pass through the subcooler 300 for condensation and heat dissipation, and ultimately flow to the subsequent intermediate heat exchanger 400 through the fifth channel 48. The valve device is connected to the fifth channel 48 through the third channel 46, and the fourth channel 47 can be connected to the fifth channel 48 in one direction through the second valve component 3. In this way, the valve device can not only meet the flow path switching requirements, but also simplify the connection. In addition, the valve device can be connected to other devices through ports, which simplifies the connection and makes the thermal management component structure relatively compact, which helps to reduce the space occupied by the thermal management component in the system, and thus helps to miniaturize the system.

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