[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is based on the Chinese patent application "Multi-way valve, integrated module, thermal management system and vehicle" with application number 202311453055.3 and application date November 2, 2023, and claims the priority of the above-mentioned Chinese patent application. The entire content of the above-mentioned Chinese patent application is hereby introduced into this application as a reference. Technical Field

[0003] The present application belongs to the technical field of switching valves, specifically to a multi-way valve, an integrated module, a thermal management system and a vehicle. Background Art

[0004] In the existing technology, in order for the thermal management system to meet the heating or cooling needs of the entire vehicle for the motor, battery or passenger compartment, it is usually necessary to design a complex circuit and use multiple valves to adjust the connection relationship between the circuits according to the needs of the thermal management system. However, due to the large number of valves set, the thermal management system occupies a large space and has a low degree of integration, which increases costs and difficulty in control.

[0005] Summary of the Invention

[0006] To this end, the present application proposes a multi-way valve, which has a high degree of integrated design, a simple structure and a compact size, so as to reduce the cost of the integrated module and the thermal management system, and solve the technical problems in the prior art that multiple valves are required, resulting in a large space occupied by the thermal management system, a low degree of integration, high cost and high control difficulty.

[0007] In the first aspect, the multi-way valve according to the embodiment of the present application includes: a valve body, which is provided with at least five valve ports; a valve core, which is rotatably arranged in the valve body, and the valve core includes a first flow channel and a second flow channel arranged at intervals, the first flow channel is used to communicate with the two valve ports, and the valve core rotates so that the first flow channel is used to communicate with different valve ports; the second flow channel has a switching mode and a proportional adjustment mode, and the valve core rotates so that the second flow channel switches between the switching mode and the proportional adjustment mode, in the switching mode, the second flow channel is used to communicate with the two valve ports and connect to different valve ports when the valve core rotates, and in the proportional adjustment mode, the second flow channel is used to communicate with at least three valve ports and change the connection area with at least one valve port when the valve core rotates.

[0008] In the technical solution of the embodiment of the present application, a first flow channel and a second flow channel are set at intervals, and the second flow channel is set to have a switching mode and a proportional adjustment mode. In this way, while making the structure of the multi-way valve of the present application simple, the multi-way valve of the present application can also have a switching function and a proportional adjustment function at the same time, so that a multi-way valve can replace a three-way valve and a four-way valve at the same time, thereby improving the integration of the multi-way valve and expanding the adaptability of the multi-way valve. In this way, the multi-way valve is applied to the thermal management system and the integrated module, which can effectively improve the integration of the thermal management system and the integrated module, and reduce the control difficulty and cost of the thermal management system and the integrated module.

[0009] Optionally, the at least five valve ports include a central valve port and a plurality of peripheral valve ports, the peripheral valve ports being spaced apart around the central valve port, the first flow channel communicating with the central valve port, the valve core rotating to allow the first flow channel to communicate with different peripheral valve ports, and the second flow channel being used to communicate with at least two of the peripheral valve ports to switch between the switching mode and the proportional adjustment mode. This allows the multi-way valve of the present application to simultaneously have both switching and proportional adjustment functions, thereby enabling a single multi-way valve to replace both a three-way valve and a four-way valve, thereby improving the integration of the multi-way valve and ensuring the functionality of the multi-way valve.

[0010] Optionally, the valve core is provided with an annular blocking protrusion that abuts against the valve body and surrounds the central valve opening. While preventing the blocking protrusion from blocking the central valve opening, the blocking protrusion can also be used to reduce the contact area between the valve core and the valve body, thereby reducing friction between the valve core and the valve body, ensuring that the valve core can effectively rotate relative to the valve body and reducing the difficulty of rotation.

[0011] Optionally, the plurality of peripheral valve ports include a first valve port, a second valve port, a third valve port, and a fourth valve port, wherein the first valve port and the second valve port are symmetrically arranged relative to the central valve port, and the third valve port and the fourth valve port are symmetrically arranged relative to the central valve port. This reduces the difficulty of molding the plurality of peripheral valve ports and ensures that, when the valve core rotates, the first flow channel can communicate with the central valve port and one of the peripheral valve ports, and the second flow channel can communicate with at least two peripheral valve ports, thereby facilitating the switching and proportional adjustment functions of the multi-way valve and improving the integration of the multi-way valve.

[0012] Optionally, the second flow channel is formed as an arc-shaped flow channel. In this way, when the external medium flows along the second flow channel, the resistance of the second flow channel to the external medium can be reduced, thereby reducing the pressure drop and flow loss of the external medium and ensuring the performance of the multi-way valve.

[0013] Optionally, the central angle of the second flow channel is not less than 180°, so as to ensure that when the valve core rotates, the second flow channel can communicate with at least two peripheral valve ports, thereby ensuring the performance of the multi-way valve and facilitating the switching function and proportional adjustment function of the multi-way valve.

[0014] Optionally, the first flow channel includes a first portion and a second portion, wherein the first end of the first portion communicates with the central valve port, and the second end of the first portion communicates with the second portion, the second portion being formed as an arcuate flow channel and configured to communicate with different peripheral valve ports. This allows for communication between the central valve port and different peripheral valve ports, thereby ensuring the functionality of the multi-way valve and facilitating switching between multiple modes.

[0015] Optionally, the valve core rotates so that the first flow channel can communicate with any one of the plurality of peripheral valve ports. In other words, the first flow channel can connect the central valve port to any of the peripheral valve ports. This allows the multi-way valve to have multiple operating modes and switch between them without increasing the cost of the multi-way valve, greatly expanding the adaptability of the multi-way valve.

[0016] Optionally, the valve core rotates so that the second flow channel can communicate with any two adjacent peripheral valve ports or any three adjacent peripheral valve ports. In other words, the second flow channel can connect any two adjacent peripheral valve ports, or any three adjacent peripheral valve ports. When any two adjacent peripheral valve ports are connected, they can be used to achieve function switching, and when any three adjacent peripheral valve ports are connected, they can be used for proportional adjustment. This allows the multi-way valve of the present application to have both mode switching and proportional adjustment functions, expanding the adaptability of the multi-way valve.

[0017] Optionally, the valve core includes a disc body having a first opening and a second opening; a hollow first protrusion and a hollow second protrusion, the first protrusion and the second protrusion being spaced apart from each other on the disc body, the inner cavity of the first protrusion communicating with the first opening to define the first flow channel, and the inner cavity of the second protrusion communicating with the second opening to define the second flow channel. This reduces the difficulty of molding the first and second flow channels, thereby reducing the difficulty of molding the valve core and improving the manufacturing efficiency of the multi-way valve.

[0018] Optionally, the multi-way valve further includes a driver connected to the valve core to drive the valve core to rotate; the driver and the plurality of valve ports are respectively disposed on opposite side walls of the valve body along the rotation axis of the valve core. This ensures that the valve core can effectively rotate relative to the valve body while simplifying the installation of the driver and preventing the driver from obstructing the connection between the valve ports and external structural components, thereby reducing the difficulty of assembling the multi-way valve.

[0019] In the second aspect, the integrated module according to the embodiment of the present application includes: a flow channel plate, which is provided with multiple switching channels; a multi-way valve, which is the aforementioned multi-way valve, and the multi-way valve is provided on the flow channel plate, and the multiple valve ports are connected to the multiple switching channels, and the valve core rotates to enable the integrated module to switch between different circulation modes.

[0020] In the technical solution of the embodiment of the present application, by adopting the multi-way valve described in the above embodiment, the integration of the integrated module can be effectively improved, the adaptability of the integrated module can be expanded, and the control difficulty and cost of the integrated module can be reduced.

[0021] In a third aspect, a thermal management system according to an embodiment of the present application includes the aforementioned multi-way valve.

[0022] In the technical solution of the embodiment of the present application, by adopting the multi-way valve described in the above embodiment, the integration of the thermal management system can be effectively improved, and the control difficulty and cost of the thermal management system can be reduced.

[0023] In a fourth aspect, a vehicle according to an embodiment of the present application includes the aforementioned integrated module or the aforementioned thermal management system.

[0024] In the technical solution of the embodiment of the present application, the integrated module or thermal management system described in the above embodiment is adopted to reduce the manufacturing cost of the vehicle, ensure the working performance of the vehicle, and improve the space utilization of the vehicle.

[0025] Additional aspects and advantages of the present application will be given in part in the description below, and in part will become obvious from the description below, or will be learned through practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0051] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0052] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first" and "second" in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary-secondary relationship.

[0053] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0054] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," and "attached" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0055] The term "and / or" in this application simply describes an association between related objects, indicating that three possible relationships exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0056] In the embodiments of this application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components in different embodiments are omitted. It should be understood that the thickness, length, width, and other dimensions of the various components in the embodiments of this application, as well as the overall thickness, length, width, and other dimensions of the integrated device shown in the drawings are merely illustrative and should not constitute any limitation on this application.

[0057] The term "plurality" used in this application refers to two or more (including two).

[0058] Valves are used in thermal management systems to switch the connection between different circuits in the thermal management system according to demand, so that the thermal management system can meet the heating or cooling needs of the entire vehicle for the motor, battery or passenger compartment, ensuring the vehicle's comfort, safety and range.

[0059] However, the applicant has noticed that in order to achieve the connection relationship between different circuits, multiple valves are usually required. However, the coordination of multiple valves will cause the thermal management system to occupy a larger space and have a lower degree of integration, thereby increasing the cost and control difficulty of the thermal management system.

[0060] In order to solve the above problems, the embodiment of the present application provides a multi-way valve 1000, and the specific solution is to set at least five valve ports 110 on the valve body 100, and set a first flow channel 210 and a second flow channel 220 spaced apart on the valve core 200, and set the first flow channel 210 to be able to communicate with the two valve ports 110. In this way, when the valve core 200 rotates, the first flow channel 210 can be used to connect different valve ports 110 to achieve switching between different modes, thereby achieving the connection relationship between different circuits in the switching thermal management system, and the second flow channel 220 is set to be able to communicate with two valve ports 110 or with three valve ports 110. When the valve core 200 rotates to connect the second flow channel 220 When two different valve ports 110 are connected, switching between different modes can be achieved. When the valve core 200 is rotated to connect the second flow channel 220 to three different valve ports 110 and the connection area between the second flow channel 220 and at least one valve port 110 is changed, proportional adjustment of the valve port 110 can be achieved, so that the multi-way valve 1000 of the present application can replace a three-way valve and a four-way valve at the same time, improve the integration of the multi-way valve 1000, and expand the adaptability of the multi-way valve 1000. Moreover, since the present application only has the first flow channel 210 and the second flow channel 220, the structure of the valve core 200 can also be simplified, thereby making the multi-way valve 1000 simple in structure, reducing the manufacturing difficulty of the multi-way valve 1000 and improving manufacturing efficiency.

[0061] The multi-way valve 1000 according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0062] 1 to 4 , a multi-way valve 1000 according to an embodiment of the present application includes a valve body 100 and a valve core 200 .

[0063] 1 , 2 , and 3 , the valve body 100 is provided with at least five valve ports 110. The valve ports 110 are used to achieve communication between the inside and outside of the multi-way valve 1000, thereby ensuring that external media can flow into the multi-way valve 1000 through the valve ports 110, and that external media that have flowed into the multi-way valve 1000 can flow out through the valve ports 110, thereby achieving the delivery of the external media.

[0064] When different valve ports 110 are connected, switching between multiple modes can be achieved.

[0065] In some embodiments, the valve port 110 is connected to an external pipeline, such as a water pump, a motor cooling line, a battery heating line and cooling line, a cabin heating line, etc. This facilitates the use of the valve port 110 to discharge external media into the external pipeline or to transport external media to the multi-way valve 1000 through the external pipeline, thereby facilitating the use of the multi-way valve 1000 to control the flow direction of the external media.

[0066] It should be noted that the external medium mentioned here can be water, refrigerant or other liquids.

[0067] The valve core 200 is rotatably disposed within the valve body 100. As shown in Figures 4, 5, and 6, the valve core 200 includes a first flow channel 210 and a second flow channel 220. The first flow channel 210 and the second flow channel 220 are spaced apart. The first flow channel 210 is used to communicate with two valve ports 110. The valve core 200 rotates so that the first flow channel 210 is used to communicate with different valve ports 110. In other words, when the valve core 200 rotates relative to the valve body 100, the first flow channel 210 can be controlled to communicate with different valve ports 110, thereby achieving switching between multiple modes and giving the multi-way valve 1000 a mode switching function.

[0068] It should also be noted that the term "connected" herein refers to the ability of external media to flow between the two. For example, when two valve ports 110 are connected via the first flow channel 210, external media flowing through one valve port 110 can flow to the other valve port 110 via the first flow channel 210. Similarly, external media flowing through the other valve port 110 can also flow to one valve port 110 via the first flow channel 210, thereby achieving the flow of external media and ensuring the performance of the thermal management system 3000.

[0069] The second flow channel 220 has a switching mode and a proportional adjustment mode. The valve core 200 rotates to switch the second flow channel 220 between the switching mode and the proportional adjustment mode. In the switching mode, the second flow channel 220 is used to communicate with two valve ports 110 and connect to different valve ports 110 when the valve core 200 rotates. In the proportional adjustment mode, the second flow channel 220 is used to communicate with at least three valve ports 110 and change the connection area with at least one valve port 110 when the valve core 200 rotates. Here, it means that the second flow channel 220 can be connected to two valve ports 110, or to at least three valve ports 110, wherein at least three valve ports 110 refer to three valves 110 or more than three valves 110, that is, in the proportional adjustment mode, the second flow channel 220 is used to connect to three valve ports 110 or to connect to more than three valves 110. When the second flow channel 220 is connected to two valve ports 110 and the valve core 200 rotates, the second flow channel 220 can be controlled to connect to different valve ports 110, thereby realizing switching between multiple modes; when the second flow channel 220 is connected to at least three valve ports 110 and the valve core 200 rotates, the connection area between the second flow channel 220 and at least one valve port 110 can be changed, thereby realizing proportional adjustment, so that the multi-way valve 1000 of the present application can have both mode switching function and proportional adjustment function, thereby expanding the adaptability of the multi-way valve 1000.

[0070] In some examples, as shown in Figures 10, 13, 16 and 19, in the proportional adjustment mode, the second flow channel 220 is used to communicate with three valve ports 110 arranged in sequence, and when the valve core 200 rotates, the communication area of ​​the valve ports 110 connected to both ends of the second flow channel 220 can be changed.

[0071] At the same time, the above-mentioned setting can also enable the multi-way valve 1000 of the present application to replace a three-way valve and a four-way valve, thereby improving the integration of the multi-way valve 1000. In this way, the multi-way valve 1000 is applied to the thermal management system 3000, which can effectively improve the integration of the thermal management system 3000 and reduce the control difficulty and cost of the thermal management system 3000.

[0072] It is worth noting that the present application can achieve mode switching and proportional adjustment through the cooperation of the first flow channel 210 and the second flow channel 220. In this way, while expanding the adaptability of the multi-way valve 1000, it can also simplify the structure of the multi-way valve 1000, making the structure of the multi-way valve 1000 simple, thereby reducing the manufacturing difficulty of the multi-way valve 1000.

[0073] That is to say, the multi-way valve 1000 of the present application has a simple structure, low manufacturing difficulty and high degree of integration. It can simultaneously meet the mode switching function and proportional adjustment function of the combination of a three-way valve and a four-way valve to meet the needs of the thermal management system 3000 and reduce the cost of the thermal management system 3000.

[0074] In some examples, when the valve core 200 rotates relative to the valve body 100, the valve core 200 drives the first flow channel 210 and the second flow channel 220 to rotate synchronously, so that the first flow channel 210 can connect to different valve ports 110, and the second flow channel 220 can connect to valve ports 110 at different positions and different numbers, and the connection area between the second flow channel 220 and at least one valve port 110 can be controlled to ensure the working performance of the multi-way valve 1000.

[0075] It should also be noted that when the first flow channel 210 and the second flow channel 220 are rotated to overlap or partially overlap with the corresponding valve port 110, the first flow channel 210 and the second flow channel 220 can be connected to the valve port 110. At this time, the external medium can flow into the first flow channel 210 and the second flow channel 220 through the valve port 110, and the external medium in the first flow channel 210 and the second flow channel 220 can also be discharged through the valve port 110; when the first flow channel 210 and the second flow channel 220 are rotated to be staggered with the valve port 110, the first flow channel 210 and the second flow channel 220 are not connected to the valve port 110. At this time, the external medium cannot flow into the first flow channel 210 and the second flow channel 220, and the external medium located in the first flow channel 210 and the second flow channel 220 cannot be discharged.

[0076] In addition, by changing the overlapping range between the second flow channel 220 and the corresponding valve port 110 , the communication area between the second flow channel 220 and the corresponding valve port 110 can be changed.

[0077] The larger the overlapping range between the second flow channel 220 and the corresponding valve port 110 , the larger the communication area between the second flow channel 220 and the corresponding valve port 110 , which facilitates proportional adjustment.

[0078] It can be seen from the above structure that the multi-way valve 1000 of the embodiment of the present application is provided with a first flow channel 210 and a second flow channel 220 spaced apart on the valve core 200, and at least five valve ports 110 are provided on the valve body 100, and the valve core 200 is rotatably provided in the valve body 100. In this way, the first flow channel 210, the second flow channel 220 and the multiple valve ports 110 can be used to cooperate with each other to make the multi-way valve 1000 of the present application simple in structure, and the multi-way valve 1000 can also have a switching function and a proportional adjustment function at the same time, so that a multi-way valve 1000 can simultaneously replace a three-way valve and a four-way valve, thereby improving the integration of the multi-way valve 1000 and expanding the adaptability of the multi-way valve 1000. In this way, the multi-way valve 1000 is applied to the thermal management system 3000, which can effectively improve the integration of the thermal management system 3000 and reduce the control difficulty and cost of the thermal management system 3000.

[0079] It can be understood that, compared with the prior art, the present application sets a first flow channel 210 and a second flow channel 220 on the valve core 200, and sets at least five valve ports 110 on the valve body 100. The first flow channel 210, the second flow channel 220 and the multiple valve ports 110 cooperate with each other. While simplifying the structure of the multi-way valve 1000, it can also improve the integration of the multi-way valve 1000 and expand the adaptability of the multi-way valve 1000, so as to improve the integration of the thermal management system 3000 and reduce the control difficulty and cost of the thermal management system 3000.

[0080] In some embodiments, as shown in Figures 1, 2, and 3, at least five valve ports 110 are provided on the bottom wall of the valve body 100. Forming the valve ports 110 on the bottom surface of the valve body 100 reduces the difficulty of molding the valve ports 110 and the difficulty of coordinating the valve ports 110 with the first flow channel 210 and the second flow channel 220. Furthermore, water inlet and outlet can be achieved at the same end of the multi-way valve 1000, further simplifying the structure of the multi-way valve 1000, making the multi-way valve 1000 smaller and easier to control.

[0081] In other words, the multi-way valve 1000 of the present application has a simple and compact structure.

[0082] Optionally, the valve body 100 and the valve core 200 are coaxially arranged to ensure that the valve core 200 can effectively rotate relative to the valve body 100, thereby facilitating mode switching and proportional adjustment using the multi-way valve 1000.

[0083] In some embodiments, as shown in Figures 4, 5 and 7, the valve body 100 has a accommodating cavity 120 with a top opening, and the valve core 200 can be rotatably arranged in the accommodating cavity 120 through the top opening to achieve rotational coordination between the valve body 100 and the valve core 200, while also reducing the difficulty of assembling the valve body 100 and the valve core 200.

[0084] In some embodiments, as shown in Figures 1 and 2, the valve body 100 also includes an upper cover 130, which is detachably connected to the opening of the accommodating chamber 120 to close the opening, thereby facilitating the use of the valve body 100 to protect the valve core 200 and extend the service life of the valve core 200. At the same time, it can also prevent external debris from entering the accommodating chamber 120, ensure that the valve core 200 can effectively rotate relative to the valve body 100, and ensure the working performance of the multi-way valve 1000.

[0085] Optionally, as shown in FIG. 1 , the upper cover 130 is detachably connected to the opening of the accommodating cavity 120 via a fastener 140 to reduce the difficulty of connecting the upper cover 130 .

[0086] The fastener 140 mentioned here may be a bolt, a screw, etc.

[0087] In some embodiments, as shown in Figures 2 and 3, at least five valve ports 110 include a central valve port 111 and multiple peripheral valve ports 112, and the peripheral valve ports 112 are spaced apart around the central valve port 111. The first flow channel 210 is connected to the central valve port 111, and the valve core 200 rotates so that the first flow channel 210 is connected to different peripheral valve ports 112. The second flow channel 220 is used to connect at least two peripheral valve ports 112 to switch between the switching mode and the proportional adjustment mode. What this means is that the first flow channel 210 is always connected to the central valve port 111, and when the valve core 200 rotates relative to the valve body 100, the first flow channel 210 can be connected to different peripheral valve ports 112, so that the central valve port 111 can be connected to different peripheral valve ports 112 during the rotation of the valve core 200, and each time a peripheral valve port 112 is connected, a mode can be switched, thereby realizing switching between multiple modes; the second flow channel 220 is connected to at least two peripheral valve ports 112, so that the second flow channel 220 switches between the switching mode and the proportional adjustment mode, so that the multi-way valve 1000 can switch between the switching mode and the proportional adjustment mode, and the multi-way valve 1000 has a switching function and a proportional adjustment function, so as to realize the use of a multi-way valve 1000 to replace a three-way valve and a four-way valve at the same time, improve the integration of the multi-way valve 1000, and ensure the function of the multi-way valve 1000.

[0088] 10 , 13 , 16 and 19 respectively show schematic diagrams of the first flow channel 210 being in communication with different peripheral valve ports 112 .

[0089] It should be noted that the second flow channel 220 mentioned above is used to connect at least two peripheral valve ports 112, which means that the second flow channel 220 can connect to two peripheral valve ports 112 at the same time, and can also connect to more than two peripheral valve ports 112 at the same time. When the second flow channel 220 connects to two peripheral valve ports 112 at the same time, during the rotation of the valve core 200, the second flow channel 220 can be controlled to connect to two different peripheral valve ports 112, and the connected peripheral valve ports 112 are different, which can make the operating mode of the multi-way valve 1000 different, thereby realizing switching between multiple modes. That is, the second flow channel 220 has a switching mode; when the second flow channel 220 is connected to multiple peripheral valve ports 112 (such as three peripheral valve ports 112) at the same time, during the rotation of the valve core 200, the second flow channel 220 can be controlled to connect with three different peripheral valve ports 112 and the connection area between the second flow channel 220 and at least one peripheral valve port 112 can be changed. The different connection areas will result in different flow rates of the external medium flowing through the peripheral valve ports 112, thereby realizing mode switching and proportional adjustment, that is, the second flow channel 220 has a proportional adjustment mode.

[0090] 9 , 11 , 12 and 14 respectively show schematic diagrams of the second flow channel 220 being connected to two different peripheral valve ports 112 ; and FIG. 10 , 13 , 16 and 19 respectively show schematic diagrams of the second flow channel 220 being connected to three different peripheral valve ports 112 .

[0091] In some embodiments, as shown in conjunction with Figures 4, 6, and 7, the valve core 200 is provided with an annular blocking protrusion 230, which abuts against the valve body 100 and is disposed around the central valve port 111. By abutting the blocking protrusion 230 against the valve body 100, the blocking protrusion 230 can be utilized to reduce the contact area between the valve core 200 and the valve body 100, thereby reducing the friction between the valve core 200 and the valve body 100, ensuring that the valve core 200 can effectively rotate relative to the valve body 100 and reducing the difficulty of rotation, thereby ensuring the working performance of the multi-way valve 1000.

[0092] In addition, setting the blocking protrusion 230 around the central valve port 111 can also prevent the blocking protrusion 230 from blocking the central valve port 111, thereby preventing the blocking protrusion 230 from blocking the external medium from flowing through the central valve port 111, thereby ensuring the sealing and diversion effect of the central valve port 111.

[0093] Optionally, the blocking protrusion 230 is integrally formed with the valve core 200. That is, the blocking protrusion 230 is integrally formed on the valve core 200 to reduce the difficulty of forming the blocking protrusion 230, while also improving the position stability of the blocking protrusion 230 and ensuring the working performance of the blocking protrusion 230.

[0094] In some embodiments, as shown in FIG3 and FIG8 , the plurality of peripheral valve ports 112 include a first valve port 1121, a second valve port 1122, a third valve port 1123, and a fourth valve port 1124. The first valve port 1121 and the second valve port 1122 are symmetrically arranged relative to the central valve port 111, and the third valve port 1123 and the fourth valve port 1124 are symmetrically arranged relative to the central valve port 111. This reduces the difficulty of molding the plurality of peripheral valve ports 112 and ensures that when the valve core 200 rotates, the first flow channel 210 can communicate with the central valve port 111 and one of the peripheral valve ports 112, and the second flow channel 220 can communicate with at least two peripheral valve ports 112, thereby facilitating the switching function and proportional adjustment function of the multi-way valve 1000 and improving the integration of the multi-way valve 1000.

[0095] In some embodiments, as shown in Figure 8, the central valve port 111 is arranged at the center position of the bottom wall of the valve body 100, and multiple peripheral valve ports 112 are arranged at intervals around the central valve port 111, and the distance between the same peripheral valve port 112 and the two adjacent peripheral valve ports 112 is consistent, so that the first valve port 1121, the second valve port 1122, the third valve port 1123 and the fourth valve port 1124 are evenly arranged in the circumferential direction of the central valve port 111.

[0096] Through the above configuration, the multi-way valve 1000 can have multiple modes to expand the adaptability of the multi-way valve 1000.

[0097] In some examples, as shown in FIG. 9 , in the first working mode, the valve core 200 rotates so that the first flow channel 210 is connected to the central valve port 111 and the third valve port 1123 , and the second flow channel 220 is connected to the second valve port 1122 and the fourth valve port 1124 .

[0098] As shown in Figure 10, in the second working mode, the valve core 200 rotates to connect the first flow channel 210 with the central valve port 111 and the third valve port 1123 respectively, and the second flow channel 220 with the first valve port 1121, the second valve port 1122, and the fourth valve port 1124 respectively.

[0099] As shown in FIG. 11 , in the third working mode, the valve core 200 rotates so that the first flow channel 210 is connected to the central valve port 111 and the third valve port 1123 , and the second flow channel 220 is connected to the first valve port 1121 and the fourth valve port 1124 .

[0100] As shown in FIG. 12 , in the fourth working mode, the valve core 200 rotates so that the first flow channel 210 is connected to the central valve port 111 and the fourth valve port 1124 respectively, and the second flow channel 220 is connected to the first valve port 1121 and the third valve port 1123 respectively.

[0101] As shown in FIG13 , in the fifth working mode, the valve core 200 rotates so that the first flow channel 210 is connected to the central valve port 111 and the fourth valve port 1124 respectively, and the second flow channel 220 is connected to the first valve port 1121 , the third valve port 1123 , and the second valve port 1122 respectively.

[0102] As shown in FIG. 14 , in the sixth working mode, the valve core 200 rotates so that the first flow channel 210 is connected to the central valve port 111 and the fourth valve port 1124 respectively, and the second flow channel 220 is connected to the third valve port 1123 and the second valve port 1122 respectively.

[0103] As shown in FIG. 15 , in the seventh working mode, the valve core 200 rotates so that the first flow channel 210 is connected to the central valve port 111 and the first valve port 1121 respectively, and the second flow channel 220 is connected to the third valve port 1123 and the second valve port 1122 respectively.

[0104] As shown in Figure 16, in the eighth working mode, the valve core 200 rotates so that the first flow channel 210 is connected to the central valve port 111 and the first valve port 1121 respectively, and the second flow channel 220 is connected to the third valve port 1123, the second valve port 1122, and the fourth valve port 1124 respectively.

[0105] As shown in FIG. 17 , in the ninth working mode, the valve core 200 rotates so that the first flow channel 210 is connected to the central valve port 111 and the first valve port 1121 , and the second flow channel 220 is connected to the second valve port 1122 and the fourth valve port 1124 .

[0106] As shown in FIG. 18 , in the tenth working mode, the valve core 200 rotates so that the first flow channel 210 is connected to the central valve port 111 and the second valve port 1122 respectively, and the second flow channel 220 is connected to the fourth valve port 1124 and the first valve port 1121 respectively.

[0107] As shown in Figure 19, in the eleventh working mode, the valve core 200 rotates so that the first flow channel 210 is connected to the central valve port 111 and the second valve port 1122 respectively, and the second flow channel 220 is connected to the fourth valve port 1124, the first valve port 1121, and the third valve port 1123 respectively.

[0108] As shown in FIG. 20 , in the twelfth working mode, the valve core 200 rotates so that the first flow channel 210 is connected to the central valve port 111 and the second valve port 1122 respectively, and the second flow channel 220 is connected to the first valve port 1121 and the third valve port 1123 respectively.

[0109] It should be noted that the above working modes are only examples and do not represent limitations on this application.

[0110] In summary, the present application creatively sets the position of the valve port 110 and sets the coordination relationship between the first flow channel 210, the second flow channel 220 and the valve port 110, so that the multi-way valve 1000 can output an additional six modes in addition to the modes output by the traditional three-way valve and four-way valve combination. In this way, the adaptability of the multi-way valve 1000 can be greatly expanded without increasing the cost of the multi-way valve 1000.

[0111] Among them, the first working mode in Figure 9, the third working mode in Figure 11, the fourth working mode in Figure 12, the sixth working mode in Figure 14, the seventh working mode in Figure 15, the ninth working mode in Figure 17, the tenth working mode in Figure 18 and the twelfth working mode in Figure 20 are used to perform the mode switching function; the second working mode in Figure 10, the fifth working mode in Figure 13, the eighth working mode in Figure 16 and the eleventh working mode in Figure 19 are used to perform the proportional adjustment function. Compared with the combination of traditional three-way valves and four-way valves, the multi-way valve 1000 not only reduces the cost, but also further improves the breadth of its application.

[0112] In some embodiments, as shown in FIG6 , the second flow channel 220 is formed as an arc-shaped flow channel. This reduces the resistance of the second flow channel 220 to the external medium when the external medium flows along the second flow channel 220 , thereby reducing the pressure drop and flow loss of the external medium and ensuring the performance of the multi-way valve 1000 .

[0113] In some embodiments, the central angle of the second flow channel 220 is not less than 180°. In other words, the central angle of the second flow channel 220 is greater than 180° to ensure that when the valve core 200 rotates, the second flow channel 220 can communicate with at least two peripheral valve ports 112, thereby ensuring the performance of the multi-way valve 1000 and facilitating the switching function and proportional adjustment function of the multi-way valve 1000.

[0114] In some examples, the central angle of the second flow channel 220 is equal to 180°. When the central angle of the second flow channel 220 is too small, the second flow channel 220 cannot simultaneously connect to at least three peripheral valve ports 112, thereby causing the multi-way valve 1000 to lose its proportional adjustment function. When the central angle of the second flow channel 220 is too large, the second flow channel 220 occupies the layout space of the first flow channel 210, thereby making it impossible to install the first flow channel 210 on the valve core 200, or making it impossible to install the first flow channel 210 and the second flow channel 220 separately, thereby affecting the performance of the multi-way valve 1000.

[0115] Therefore, the present application sets the central angle of the second flow channel 220 to be equal to 180°. In this way, while ensuring that the second flow channel 220 can simultaneously connect to at least three peripheral valve ports 112, it can also avoid the second flow channel 220 occupying the layout space of the first flow channel 210, and enable the first flow channel 210 and the second flow channel 220 to be arranged at intervals to ensure the working performance of the multi-way valve 1000.

[0116] In some embodiments, as shown in FIG6 , the first flow channel 210 includes a first portion 211 and a second portion 212. The first end of the first portion 211 communicates with the central valve port 111, and the second end of the first portion 211 communicates with the second portion 212. The second portion 212 is formed as an arcuate flow channel, and the second portion 212 is used to communicate with different peripheral valve ports 112. By configuring the first flow channel 210 to include the first portion 211 and the second portion 212, the first flow channel 210 can be respectively communicated with the central valve port 111 and one of the peripheral valve ports 112. Thus, when the valve core 200 rotates relative to the valve body 100, the central valve port 111 can be communicated with different peripheral valve ports 112, thereby achieving switching between multiple modes.

[0117] At the same time, by forming the second part 212 into an arc-shaped flow channel, while reducing the difficulty of forming the second part 212, the resistance of the second part 212 to the external medium can also be reduced, thereby reducing the pressure drop and flow loss of the external medium and ensuring the performance of the multi-way valve 1000.

[0118] In some embodiments, the valve core 200 rotates so that the first flow channel 210 can communicate with any one of the plurality of peripheral valve ports 112. In other words, the first flow channel 210 can connect the central valve port 111 with any of the peripheral valve ports 112. This allows the multi-way valve 1000 to have multiple operating modes and switch between the multiple operating modes without increasing the cost of the multi-way valve 1000, greatly expanding the adaptability of the multi-way valve 1000.

[0119] 10 , 13 , 16 and 19 respectively show schematic diagrams of the first flow channel 210 being connected to the third valve port 1123 , the fourth valve port 1124 , the first valve port 1121 and the second valve port 1122 .

[0120] Optionally, the central angle of the second portion 212 is not less than 90°. In other words, the central angle of the second portion 212 is greater than 90° to ensure that when the valve core 200 rotates, the second portion 212 can always be connected to one peripheral valve port 112, thereby ensuring the performance of the multi-way valve 1000.

[0121] In some examples, the central angle of the second portion 212 is equal to 90°. When the central angle of the second portion 212 is too small, the second portion 212 may not be able to communicate with the peripheral valve port 112 when the valve core 200 rotates. For example, as shown in FIG10 and FIG11 , if the central angle of the second portion 212 is too small, the peripheral valve port 112 may not be fully connected to the second portion 212 when the second portion 212 rotates from the position in FIG10 to the position in FIG11 , thereby affecting the operating performance of the multi-way valve 1000. When the central angle of the second portion 212 is too large, there is a risk that the second portion 212 may simultaneously communicate with two peripheral valve ports 112. Furthermore, the first flow channel 210 and the second flow channel 220 may not be spaced apart, thereby affecting the operating performance of the multi-way valve 1000.

[0122] Therefore, the present application sets the central angle of the second part 212 to be equal to 90°, so that when the second part 212 completely covers one of the peripheral valve ports 112, the second part 212 can be spaced apart from the peripheral valve port 112 adjacent to the peripheral valve port 112 (as shown in Figures 9, 10 and 11). This ensures that the second part 212 can always be connected to one peripheral valve port 112, while also avoiding the second part 212 occupying the layout space of the second flow channel 220, and allowing the first flow channel 210 and the second flow channel 220 to be spaced apart to ensure the working performance of the multi-way valve 1000.

[0123] In summary, there are a first flow channel 210 and a second flow channel 220 on the valve core 200. In the circumferential direction of the valve core 200, the second flow channel 220 occupies an arc of 180°, and the first flow channel 210 occupies an arc of 90°. The 180° flow channel can be used to realize both the mode switching function and the proportional adjustment function, and the 90° flow channel is only used to realize the mode switching function.

[0124] In some embodiments, the central angle of the second portion 212 is greater than the central angle corresponding to the peripheral valve ports 112 and less than or equal to the central angle corresponding to the area between the centers of two adjacent peripheral valve ports 112. This ensures that the second portion 212 can effectively communicate with one of the peripheral valve ports 112 and prevents the other end of the second portion 212 from simultaneously communicating with a peripheral valve port 112 when one end of the second portion 212 is communicating with one of the peripheral valve ports 112. This ensures that the second portion 212 can always communicate with one of the peripheral valve ports 112, thereby ensuring the working performance of the multi-way valve 1000.

[0125] In some embodiments, the valve core 200 rotates so that the second flow channel 220 can communicate with any two adjacent ones or any three adjacent ones of the plurality of peripheral valve ports 112. That is, during the rotation of the valve core 200, the second flow channel 220 can communicate with any two adjacent peripheral valve ports 112, or can also communicate with any three adjacent peripheral valve ports 112. When any two adjacent peripheral valve ports 112 are connected, function switching can be achieved, and when any three adjacent peripheral valve ports 112 are connected, proportional adjustment can be achieved. This allows the multi-way valve 1000 of the present application to have both mode switching and proportional adjustment functions, thereby expanding the adaptability of the multi-way valve 1000.

[0126] In some embodiments, as shown in conjunction with Figures 5 and 6 , the valve core 200 includes a disc body 240, a hollow first protrusion 250, and a hollow second protrusion 260. The disc body 240 is provided with a first opening 241 and a second opening 242. The first protrusion 250 and the second protrusion 260 are spaced apart from each other on the disc body 240. The inner cavity of the first protrusion 250 communicates with the first opening 241 to define the first flow channel 210, and the inner cavity of the second protrusion 260 communicates with the second opening 242 to define the second flow channel 220. In other words, the present application forms the first flow channel 210 and the second flow channel 220 by providing the hollow first protrusion 250 and the hollow second protrusion 260 and providing the first opening 241 and the second opening 242 on the disc body 240, thereby reducing the difficulty of molding the first flow channel 210 and the second flow channel 220, thereby reducing the difficulty of molding the valve core 200 and improving the manufacturing efficiency of the multi-way valve 1000.

[0127] In some embodiments, part of the side wall of the disc body 240 protrudes toward one side to form a hollow first protrusion 250 and a hollow second protrusion 260, and the first protrusion 250 and the second protrusion 260 are both formed with an inner cavity. In this way, while reducing the difficulty of molding the first protrusion 250 and the second protrusion 260, the structural strength of the first protrusion 250 and the second protrusion 260 can be guaranteed, and it is convenient to achieve the connection between the first protrusion 250 and the first opening 241 and the connection between the second protrusion 260 and the second opening 242, thereby reducing the difficulty of molding the first flow channel 210 and the second flow channel 220, and ensuring the structural stability of the first flow channel 210 and the second flow channel 220, thereby ensuring the diversion effect of the first flow channel 210 and the second flow channel 220.

[0128] In some embodiments, the multi-way valve 1000 further includes a driving member connected to the valve core 200 to drive the valve core 200 to rotate, thereby ensuring that the valve core 200 can effectively rotate relative to the valve body 100 to ensure the working performance of the multi-way valve 1000.

[0129] Optionally, the driving member is a driving motor, which can ensure the driving effect of the driving member while utilizing the driving member to drive the valve core 200 to rotate.

[0130] In some embodiments, as shown in FIG5 , the valve core 200 includes a connecting shaft 270 , and the valve core 200 is connected to the driving member via the connecting shaft 270 , so that the driving member can be used to drive the valve core 200 to rotate, while also reducing the difficulty of matching the driving member with the valve core 200 .

[0131] Optionally, the driver and the plurality of valve ports 110 are disposed on opposite side walls of the valve body 100 along the rotation axis of the valve core 200. This simplifies the installation of the driver and prevents the driver from obstructing the connection between the valve ports 110 and external structural components, thereby reducing the difficulty of assembling the multi-way valve 1000.

[0135] Since the multi-way valve 1000 of the embodiment of the present application has the above-mentioned technical effects, the integrated module 2000 of the embodiment of the present application also has the above-mentioned technical effects, that is, by adopting the multi-way valve 1000 of the present application, the integration of the integrated module 2000 can be effectively improved, the volume of the integrated module 2000 can be reduced, the adaptability of the integrated module 2000 can be expanded, and the control difficulty and cost of the integrated module 2000 can be reduced.

[0139] The vehicle 4000 of the fourth embodiment of the present application is described below with reference to the accompanying drawings.

[0140] As shown in Figures 21 and 22, the vehicle 4000 of the embodiment of the present application includes the integrated module 2000 or the thermal management system 3000 of the above embodiment.
