[0041] In the thermal management system of an automobile, a large number of control valves are usually arranged for control. In order to improve the integration of control valves, reduce the control difficulty, and reduce space occupation, such as Figure 1-Figure 11 As shown, the present invention provides an integrated valve. The integrated valve comprises a valve seat 1 and a first valve core.

[0042] The valve seat 1 has a hollow cavity, and the first flow channel 10, the fifth flow channel 14, the sixth flow channel 15, the second flow channel 11, the fourth flow channel 13 and the third flow channel 12 are arranged at equal intervals on the valve seat 1 in the clockwise direction, and the first proportional flow channel 16 and the second proportional flow channel 17 are arranged on the valve seat 1. The first valve core is rotatably arranged in the valve seat 1, and the first valve core includes a three-way proportional valve core 2 and a mode control valve core 3 that are fixedly connected. The three-way proportional valve core 2 corresponds to the first proportional flow channel 16 and the second proportional flow channel 17. The three-way proportional valve core 2 can control the first proportional flow channel 16 and / or the second proportional flow channel 17 to be connected to 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 are connected. The third flow channel 12 is connected with the fourth flow channel 13, and the fifth flow channel 14 is connected with 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 with the fifth flow channel 14, the second flow channel 11 is connected with the fourth flow channel 13, and the third flow channel 12 is connected with 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 with the third flow channel 12, the second flow channel 11 is connected with the sixth flow channel 15, and the fourth flow channel 13 is connected with 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 the three-way proportional valve. Through the mode control valve core 3, three different conduction modes can be switched. Through the above settings, the mode selection and the three-way proportional valve functions are integrated together, which can improve the integration, reduce the control difficulty and reduce the space occupation.

[0044] In some embodiments, the first proportional flow channel 16 and the second proportional flow channel 17 are spaced 30° apart, and the middle position of the first proportional flow channel 16 and the second proportional flow channel 17 is 0°. When the first proportional flow channel 16 is rotated 15° clockwise, the first proportional flow channel 16 is completely connected to the fifth flow channel 14. When the first proportional flow channel 16 and the second proportional flow channel 17 are rotated 15° counterclockwise, the second proportional flow channel 17 is completely connected to the fifth flow channel 14. In addition, the first proportional flow channel 16 and the second proportional flow channel 17 are both connected to the fifth flow channel 14. By rotating the first valve core, the opening of the first proportional flow channel 16 and the second proportional flow channel 17 connected to 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 also be arranged according to actual needs, and no excessive restrictions are made here.

[0045] In some embodiments, the valve seat 1 is provided with a first channel 18 and a second channel 19 at intervals, and a three-way control valve core 4 is rotatably provided in the valve seat 1. The three-way control valve core 4 is provided coaxially 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 driven by 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, the three-way control valve core 4 is driven to rotate by rotating the first valve core, thereby realizing the switching of the connection between the first channel 18, the second channel 19 and the fourth flow channel 13, and 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, it can be switched by rotating 90° counterclockwise to make the second channel 19 connected to the fourth flow channel 13, thereby realizing the function of the three-way control valve. By setting the integrated three-way valve as described above, the integration degree of the 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, and the sealing sleeve 5 is provided with 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 conduction hole 503, a second conduction hole 504 and a third conduction hole 505, the first through hole 51 is connected to the first flow channel 10, the second through hole 52 is connected to the first flow channel 10, and the 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 conduction 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 conduction hole 503 is connected to the first channel 18, and the second conduction hole 504 is connected to the second channel 19. Through the above arrangement, it is possible to prevent the fluid medium entering the integrated valve from mixing.

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

[0048] In some embodiments, a positioning rod 31 is provided at one end of the mode control valve core 3 away from the three-way proportional valve core 2, and a positioning hole is provided in the three-way proportional valve core 2, and the positioning rod 31 is passed through the positioning hole. The positioning rod 31 cooperates with the positioning hole, so that the three-way proportional valve core 2 and the mode control valve core 3 can be assembled easily.

[0049] In some embodiments, an arc-shaped limit block 42 is provided at one end of the three-way control valve core 4 away from the mode control valve core 3, and an arc-shaped limit groove is provided on the valve seat 1, and the arc-shaped limit block 42 is located in the arc-shaped limit groove. In this embodiment, the center angle corresponding to the arc-shaped limit groove is 180°, and the center angle corresponding to the arc-shaped limit block 42 is 90°. During the rotation of the three-way control valve core 4, the arc-shaped limit block 42 moves in the arc-shaped limit groove. When the arc-shaped limit block 42 abuts against the groove wall of the arc-shaped limit 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 cannot continue to rotate in the original rotation direction. 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 driving member 7, which is in transmission connection with the first valve core, and the driving member 7 can drive the first valve core to rotate relative to the valve seat 1. By providing the driving member 7, the first valve core can be driven to rotate according to actual control needs, so as to achieve precise control of the rotation angle of the first valve core. In this embodiment, the driving member 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, a chain drive or a gear drive structure can also be arranged between the motor and the first valve core, without making too many restrictions here.

[0051] In some embodiments, the integrated valve further includes a cover plate 6, which is disposed on the valve seat 1 to block the hollow cavity, the valve stem 21 of the first valve core extends relative to the cover plate 6, and the driving member 7 is in transmission connection with 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 sleeved on the valve stem 21, and the sealing ring is located between the cover plate 6 and the valve stem 21. The sealing ring can block the gap between the cover plate 6 and the valve stem 21, thereby preventing the flowing medium from flowing out of the gap between the cover plate 6 and the valve stem 21.

[0053] This embodiment also provides a thermal management system, including the above integrated valve. By using the above integrated valve in the thermal management system, it is possible to achieve three working mode adjustments and integrate the functions of a three-way valve and a three-way proportional valve, which can well meet the use of the thermal management system. In addition, the integrated valve has a high degree of integration, is less difficult to control, and occupies less space.
