[0041] In automotive thermal management systems, a large number of control valves are typically installed for control. To improve the integration of these control valves, reduce control complexity, and minimize space requirements, such as... Figures 1-11 As shown, the present invention provides an integrated valve. The integrated valve includes a valve seat 1 and a first valve core.

[0042] The valve seat 1 has a hollow cavity, and a first flow channel 10, a fifth flow channel 14, a sixth flow channel 15, a second flow channel 11, a fourth flow channel 13, and a third flow channel 12 are equally spaced along a clockwise direction on the valve seat 1. A first proportional flow channel 16 and a second proportional flow channel 17 are also provided on the valve seat 1. A first valve core is rotatably disposed in the valve seat 1. The first valve core includes a fixedly connected three-way proportional valve core 2 and a mode control valve core 3. The three-way proportional valve core 2 corresponds to the first proportional flow channel 16 and the second proportional flow channel 17, and can control the first proportional flow channel 16 and / or the second proportional flow channel 17 to communicate with the fifth flow channel 14. The mode control valve core 3 has a first control position, a second control position, and a third control position. When the mode control valve core 3 is in the first control position, the first flow channel 10 and the second flow channel 11... The first flow channel 10 is connected to the second flow channel 14, the second flow channel 11 is connected to the fourth flow channel 13, and the third flow channel 12 is connected to the sixth flow channel 15. When the mode control valve core 3 is in the second control position, the first flow channel 10 is connected to the fifth flow channel 14, the second flow channel 11 is connected to the fourth flow channel 13, and the third flow channel 12 is connected to the sixth flow channel 15. When the mode control valve core 3 is in the third control position, the first flow channel 10 is connected to the third flow channel 12, the second flow channel 11 is connected to the sixth flow channel 15, and the fourth flow channel 13 is connected to the fifth flow channel 14.

[0043] By rotating the first valve core, the three-way proportional valve core 2 can cooperate with the first proportional flow channel 16, the second proportional flow channel 17, and the fifth flow channel 14 to realize the function of a three-way proportional valve. The mode control valve core 3 can switch between three different conduction modes. By integrating the mode selection and the three-way proportional valve function together, the integration level can be improved, the control difficulty reduced, and the space occupied minimized.

[0044] In some embodiments, the first proportional flow channel 16 and the second proportional flow channel 17 are spaced 30° apart. Taking the midpoint between the first proportional flow channel 16 and the second proportional flow channel 17 as 0°, rotating 15° clockwise completely connects the first proportional flow channel 16 with the fifth flow channel 14. Rotating 15° counterclockwise completely connects the second proportional flow channel 17 with the fifth flow channel 14. Furthermore, both the first proportional flow channel 16 and the second proportional flow channel 17 are connected to the fifth flow channel 14. By rotating the first valve core, the opening degree of the connection between the first proportional flow channel 16 and the second proportional flow channel 17 and the fifth flow channel 14 can be controlled. In other embodiments, the first proportional flow channel 16 and the second proportional flow channel 17 can be arranged according to actual needs, without further restrictions.

[0045] In some embodiments, a first channel 18 and a second channel 19 are spaced apart on the valve seat 1. A three-way control valve core 4 is rotatably disposed in the valve seat 1. The three-way control valve core 4 is coaxially arranged with the first valve core, and the mode control valve core 3 is located between the three-way proportional valve core 2 and the three-way control valve core 4. The three-way control valve core 4 can rotate within a set angle under the drive of the first valve core, so that the first channel 18 or the second channel 19 is connected to the fourth flow channel 13. In this embodiment, by rotating the first valve core, the three-way control valve core 4 is driven to rotate, thereby switching the connection between the first channel 18 and the second channel 19 and the fourth flow channel 13. The first channel 18 and the second channel 19 are spaced 90° apart. When the first channel 18 is connected to the fourth flow channel 13, rotating counterclockwise by 90° can switch the connection between the second channel 19 and the fourth flow channel 13, realizing the function of the three-way control valve. By integrating the three-way valve with the above configuration, the integration level of this integrated valve can be further improved.

[0046] In some embodiments, a sealing sleeve 5 is provided between the valve seat 1 and the first valve core. The sealing sleeve 5 is sleeved on the first valve core. The sealing sleeve 5 has a first through hole 51, a second through hole 52, a third through hole 53, a fourth through hole 54, a fifth through hole 55, a sixth through hole 56, a first proportional hole 501, a second proportional hole 502, a first through hole 503, a second through hole 504, and a third through hole 505. The first through hole 51 communicates with the first flow channel 10, and the second through hole 52 communicates with the first flow channel 10. The second flow channel 11 is connected, the third through hole 53 is connected to the third flow channel 12, the fourth through hole 54 and the third through hole 505 are connected to the fourth flow channel 13, the fifth through hole 55 is connected to the fifth flow channel 14, the sixth through hole 56 is connected to the sixth flow channel 15, the first proportional hole 501 is connected to the first proportional flow channel 16, the second proportional hole 502 is connected to the second proportional flow channel 17, the first through hole 503 is connected to the first channel 18, and the second through hole 504 is connected to the second channel 19. This configuration prevents mixing of fluid media entering the integrated valve.

[0047] In some embodiments, the end of the mode control valve core 3 opposite to the three-way proportional valve core 2 has a protrusion 32, and the three-way control valve core 4 has an arc-shaped groove 41, with the protrusion 32 located in the arc-shaped groove 41. In this embodiment, the central angle corresponding to the arc-shaped groove 41 is 270°. When the first valve core rotates and the protrusion 32 is located in the arc-shaped groove 41, the first valve core can be adjusted as needed, while the three-way proportional valve core 2 will not move. Only when the protrusion 32 abuts against the side wall of the arc-shaped groove 41 and continues to rotate in the same direction can the position of the three-way proportional valve core 2 be adjusted. By using the protrusion 32 and the arc-shaped groove 41 in cooperation, the three-way proportional valve core 2 can be effectively adjusted within a set angle range, thereby realizing the function of a three-way valve. In other embodiments, the protrusion 32 can also be set on the three-way control valve core 4, and the arc-shaped groove 41 can be formed on the mode control valve core 3; no further restrictions are imposed here.

[0048] In some embodiments, a positioning rod 31 is provided at the end of the mode control valve core 3 opposite to the three-way proportional valve core 2. The three-way proportional valve core 2 has a positioning hole, and the positioning rod 31 passes through the positioning hole. The positioning rod 31 cooperates with the positioning hole to facilitate the assembly of the three-way proportional valve core 2 and the mode control valve core 3.

[0049] In some embodiments, an arc-shaped limiting block 42 is provided at one end of the three-way control valve core 4 away from the mode control valve core 3. An arc-shaped limiting groove is provided on the valve seat 1, and the arc-shaped limiting block 42 is located in the arc-shaped limiting groove. In this embodiment, the central angle corresponding to the arc-shaped limiting groove is 180°, and the central angle corresponding to the arc-shaped limiting block 42 is 90°. During the rotation of the three-way control valve core 4, the arc-shaped limiting block 42 moves in the arc-shaped limiting groove. When the arc-shaped limiting block 42 abuts against the groove wall of the arc-shaped limiting groove, it enters the dead point of the three-way control valve core 4. At this time, the first valve core and the three-way control valve core 4 can no longer continue to rotate in the original direction of rotation. The control action of the three-way control valve core 4 is completed, and the mode control adjustment and the three-way ratio adjustment can be realized by rotating the first valve core in the opposite direction.

[0050] In some embodiments, the integrated valve further includes a drive element 7, which is throttle-connected to the first valve core and can drive the first valve core to rotate relative to the valve seat 1. By providing the drive element 7, the first valve core can be driven to rotate according to actual control needs, achieving precise control of the rotation angle of the first valve core. In this embodiment, the drive element 7 is a motor, and the output shaft of the motor is directly connected to the first valve core. In other embodiments, a belt drive, chain drive, or gear drive structure can also be arranged between the motor and the first valve core, without further restrictions.

[0051] In some embodiments, the integrated valve further includes a cover plate 6, which covers the valve seat 1 to seal the hollow cavity. The valve stem 21 of the first valve core extends relative to the cover plate 6, and the drive member 7 is pulsatorically connected to the valve stem 21. By providing the cover plate 6, the hollow cavity can be sealed, thereby ensuring that the internal flowing medium does not flow out.

[0052] In some embodiments, a sealing ring is fitted onto the valve stem 21, and the sealing ring is located between the cover plate 6 and the valve stem 21. By providing the sealing ring, the gap between the cover plate 6 and the valve stem 21 can be sealed, thereby preventing the flowing medium from flowing out from the gap between the cover plate 6 and the valve stem 21.

[0053] This embodiment also provides a thermal management system, including the integrated valve described above. By employing the integrated valve in the thermal management system, it is possible to achieve regulation of three operating modes and simultaneously integrate the functions of a three-way valve and a three-way proportional valve, thus well meeting the needs of the thermal management system. Moreover, this integrated valve offers high integration, lower control difficulty, and smaller space requirements.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
