Description

Multi-way valve and vehicle thermal management system, vehicle Technical Field

[0001] The present application relates to the technical field of control valves, and in particular to a multi-way valve, a thermal management system of a vehicle, and a vehicle. Background Art

[0002] Water valves, devices that control the direction and / or flow of a medium, are installed between circuits, for example, in a vehicle's thermal management system. With the rapid development of electric vehicles, thermal management systems, as key components of electric vehicles, are becoming increasingly miniaturized, integrated, and lightweight.

[0003] In related technologies, the water channel part of the vehicle's thermal management system uses a combination of multiple three-way water valves and four-way water valves to achieve switching of various flow channel modes. The use of multiple water valves is not only costly, but also occupies more space and is heavier, which facilitates the miniaturization, integration and lightweight design of the thermal management system.

[0004] Summary of the Invention

[0005] In view of the above problems, the present application provides a multi-way valve and a vehicle thermal management system and a vehicle to achieve switching of multi-channel modes, improve integration, reduce volume and reduce cost.

[0006] To solve the above-mentioned technical problems, the present application proposes a multi-way valve. The multi-way valve comprises: a valve body having multiple accommodating chambers, multiple interfaces, and a through hole; wherein the through hole is provided between two adjacent accommodating chambers for connecting the two adjacent accommodating chambers; the side walls of the accommodating chambers are provided with interfaces for connecting the corresponding accommodating chambers with external pipelines; multiple valve cores are provided, one corresponding to the multiple accommodating chambers, and the valve cores are rotatably provided in the corresponding accommodating chambers. The valve cores are provided with multiple flow channels; at least one of the multiple valve cores rotates to switch the flow channels into different combinations, thereby connecting the interfaces into different combinations.

[0007] The valve body of the multi-way valve is provided with multiple accommodating chambers, and multiple valve cores are rotatably arranged in the corresponding accommodating chambers, so that multiple valve cores can be arranged in the same valve body to realize the integration of multiple valve cores, which can improve the integration level, reduce the volume and reduce the thermal management cost; and each valve core is provided with multiple flow channels, and the rotation of the valve core can switch the flow channels of different combinations to connect, thereby connecting the interfaces of different combinations on the valve body, thereby realizing the switching of multi-channel modes.

[0008] In some embodiments, the flow channels of the multiple valve cores are all located in the same plane, and the plane is perpendicular to the axial direction of the valve core.

[0009] All the flow channels of the valve core are located in the same plane, which can reduce the height of the valve core. Since the flow channels are used to conduct the interfaces on the valve body, a single-layer setting of the interfaces on the valve body can be achieved, thereby reducing the height of the valve body and facilitating integration with other mechanisms in the thermal management system, which can further improve the degree of integration. The flow channels in the valve core are arranged in the rotation plane of the valve core. This structure can make the height positions of the ports at both ends of the flow channels (connected to the interfaces) consistent, so that all interfaces on the valve body can be arranged in the rotation plane of the valve core, that is, the height positions of all interfaces are consistent, which can not only avoid the problem that the flow channels cannot be well connected with the interfaces on the valve body due to the rotation of the valve core, but also simplify the manufacturing process of the valve core and valve body. Since the height positions of the flow channels in the valve core are consistent, the height of the valve core can be further shortened. Since the height positions of all interfaces on the valve body are consistent, the height of the valve body can be further shortened.

[0010] In some embodiments, the multi-way valve also includes multiple guide members, which are arranged outside the valve body, and the multiple guide members are arranged in a one-to-one correspondence with the multiple interfaces. The guide members are used to connect the corresponding interfaces with external pipelines, wherein the direction of the end of the guide member facing away from the valve body is opposite to the opening direction of the accommodating cavity.

[0011] By extending the interface using the guide piece, the interface can be extended to the same plane, so that the entire multi-way valve can be connected to multiple external pipelines on the same plane, which facilitates the integrated setting of the multi-way valve and the external pipelines.

[0012] In some embodiments, the flow guide is integrally formed with the valve body.

[0013] Integral molding of the flow guide member and the valve body can improve the sealing performance between the flow guide member and the valve body and reduce the risk of coolant leakage.

[0014] In some embodiments, the flow guide member is provided with a flow guide channel, one end of the flow guide channel is communicated with the corresponding interface, and the extension direction of the other end of the flow guide channel is opposite to the opening direction of the accommodating cavity.

[0015] A valve cover, a driving mechanism, etc. are usually set on the opening side of the accommodating chamber to facilitate the control of the valve core by the driving mechanism. Therefore, setting the end of the guide channel away from the interface in the direction away from the opening of the accommodating chamber can avoid interference of the guide member on the driving mechanism, etc.

[0016] In some embodiments, the other end of the diversion channel extends to the plane where the bottom wall of the valve body is located.

[0017] The diversion channel is used to connect one end with the external pipeline and extends to the plane where the bottom wall of the valve body is located, so that the end face of the diversion channel used to connect the external pipeline is flush with the outer surface of the bottom wall of the valve body, making the bottom of the entire multi-way valve flat, and can reduce the distance between it and the external pipeline, thereby improving the stability and integration between the two.

[0018] In some embodiments, the multiple flow channels of the valve core include: a first mode flow channel, used to connect two adjacent openings on the side wall of the accommodating chamber corresponding to the valve core; and / or a second mode flow channel, used to connect two relatively set openings on the side wall of the accommodating chamber corresponding to the valve core; the valve core is rotated so that its first mode flow channel and / or second mode flow channel are respectively connected to the first mode flow channel or the second mode flow channel of the adjacent valve core to form multiple flow channel modes; wherein, the opening on the side wall of the accommodating chamber includes an interface and the through hole.

[0019] The valve core is provided with a first mode flow channel and / or a second mode flow channel, which can realize multiple flow channel modes of the multi-way valve and switching of different flow channel modes, and the flow channel lengths of different flow channel modes can be different, which can realize diversion in different directions.

[0020] In some embodiments, the plurality of valve cores includes a first valve core, and the plurality of flow passages of the first valve core includes two first mode flow passages and one second mode flow passage.

[0021] Two first mode flow channels and one second mode flow channel are set for the first valve core, and the second mode flow channel is set between the two first mode flow channels. This structure can not only realize three flow channels, but also make the flow channels compactly arranged and reduce the volume of the first valve core.

[0022] In some embodiments, the multiple valve cores include a first valve core, and the multiple flow channels of the first valve core include: two first mode flow channels and one second mode flow channel; the multiple valve cores also include a second valve core, and the multiple flow channels of the second valve core include: two first mode flow channels and one second mode flow channel; wherein, the two first mode flow channels and one second mode flow channel of the first valve core respectively form a first flow channel mode, a second flow channel mode and a third flow channel mode with a first mode flow channel of the second valve core, and respectively form a fourth flow channel mode, a fifth flow channel mode and a sixth flow channel mode with another first mode flow channel of the second valve core, and respectively form a seventh flow channel mode, an eighth flow channel mode and a ninth flow channel mode with the second mode flow channel of the second valve core.

[0023] The first valve core is equipped with two first-mode flow channels and one second-mode flow channel, with the second-mode flow channel positioned between the two first-mode flow channels. This structure not only achieves three flow channels but also enables a compact flow channel layout, reducing the volume of the first valve core. The second valve core is equipped with two first-mode flow channels and one second-mode flow channel, with the second-mode flow channel positioned between the two first-mode flow channels. This structure not only achieves three flow channels but also enables a compact flow channel layout, reducing the volume of the second valve core. The second valve core uses the same flow channel structure as the first valve core, simplifying the process, simplifying the control circuitry and control logic in the drive mechanism, and contributing to a smaller volume.

[0024] In some embodiments, the multiple valve cores include a first valve core, and the multiple flow channels of the first valve core include: two first mode flow channels and one second mode flow channel; the multiple valve cores also include a second valve core, and the multiple flow channels of the second valve core include: three first mode flow channels; wherein, the two first mode flow channels and one second mode flow channel of the first valve core are freely combined with the three first mode flow channels of the second valve core to form nine different flow channel modes.

[0025] The first valve core is provided with two first-mode flow channels and one second-mode flow channel, with the second-mode flow channel positioned between the two first-mode flow channels. This structure not only achieves three flow channels but also enables a compact flow channel layout, reducing the volume of the first valve core. The second valve core is provided with three flow channels, each of which is used to connect two adjacent openings on the side wall of the accommodating chamber, ensuring that the communication modes of the interfaces implemented by the second valve core are the same.

[0026] In some embodiments, the multiple valve cores include a first valve core, and the multiple flow channels of the first valve core include: three second mode flow channels; the multiple valve cores also include a second valve core, and the multiple flow channels of the second valve core include: three second mode flow channels; wherein, the three second mode flow channels of the first valve core are freely combined with the three second mode flow channels of the second valve core to form nine different flow channel modes.

[0027] A ten-way valve is realized by integrating two six-way valve cores with the same flow channel structure in the valve body, which has nine flow channel modes.

[0028] In some embodiments, the multi-way valve includes a first valve core, and the multiple flow channels of the first valve core include: a first mode flow channel, which is used to connect two adjacent openings on the side wall of the accommodating chamber corresponding to the first valve core; a second mode flow channel, which is used to connect two openings oppositely set on the side wall of the accommodating chamber corresponding to the first valve core; the multi-way valve also includes a second valve core, and the multiple flow channels of the second valve core include: a third mode flow channel, which is used to connect two openings set at intervals on the side wall of the accommodating chamber corresponding to the second valve core; the first valve core and the second valve core are rotated to connect the first mode flow channel and the second mode flow channel with the third mode flow channel respectively to form multiple flow channel modes; wherein, the openings on the side wall of the accommodating chamber include interfaces and through holes.

[0029] The first valve core and the second valve core adopt three different mode flow channels, which can improve the flexibility of the flow channel length and the interface position.

[0030] In some embodiments, the multiple flow channels of the first valve core include two first mode flow channels and one second mode flow channel, and the multiple flow channels of the second valve core include one third mode flow channel and one second mode flow channel; the two first mode flow channels and one second mode flow channel of the first valve core are freely combined with one third mode flow channel and one second mode flow channel of the second valve core respectively to form six different flow channel modes.

[0031] The first valve core is provided with two first-mode flow channels and one second-mode flow channel, while the second-mode flow channel is provided in the two first-mode flow channels. This structure not only realizes three flow channels but also enables a compact flow channel layout and reduces the volume of the second valve core. By integrating a first valve core of a six-way valve and a second valve core of a four-way valve in the valve body, an eight-way multi-way valve with six flow channel modes can be realized.

[0032] In some embodiments, the multiple flow channels of the first valve core include two first mode flow channels and one second mode flow channel, and the multiple flow channels of the second valve core include two third mode flow channels; the two first mode flow channels and one second mode flow channel of the first valve core are freely combined with the two third mode flow channels of the second valve core to form six different flow channel modes.

[0033] The first valve core is equipped with two first-mode flow channels and one second-mode flow channel. The second-mode flow channel is provided in two first-mode flow channels. This structure not only realizes three flow channels but also enables a compact flow channel layout, reducing the volume of the second valve core. The second valve core is equipped with two third-mode flow channels, simplifying the structure of the second valve core. Integrating a first valve core of a six-way valve and a second valve core of a four-way valve within the valve body creates an eight-way multi-way valve with six flow channel modes.

[0034] In some embodiments, the multi-way valve further includes: a valve cover, disposed on the valve body, for sealing the multiple valve cores in the corresponding accommodating cavities respectively.

[0035] The valve cover can seal the multiple accommodating cavities opened on the valve body, which can not only prevent the fluid in the valve core from leaking out of the accommodating cavities (except from the interface and the through hole), but also prevent the fluid from leaking between the accommodating cavities.

[0036] In some embodiments, the multi-way valve further includes: a driving mechanism, connected to the multiple valve cores respectively, for driving the multiple valve cores to rotate respectively.

[0037] The valve core is driven by a driving mechanism, which can improve the automation control of the multi-way valve.

[0038] In some embodiments, the driving mechanism includes: a plurality of driving members, which are arranged in one-to-one correspondence with a plurality of valve cores, and the driving members are connected to the corresponding valve cores for driving the valve cores to rotate; a shell, which is provided with a signal interface, the shell is arranged on the valve body, and the driving members are installed in the shell; a driving controller, which is installed in the shell and connected to the driving members for controlling the driving members to generate driving force; the driving controller obtains electrical signals through the signal interface, and generates control signals for controlling the driving members based on the electrical signals.

[0039] Different drive components are used to drive the valve core to rotate to corresponding positions to achieve various flow modes. The housing is used to protect the drive components, drive controller, etc.

[0040] In some embodiments, the multi-way valve further comprises: a plurality of sealing members, which are arranged in one-to-one correspondence with the plurality of valve cores, and the sealing members are arranged between the corresponding valve cores and the valve body to ensure sealed communication between the valve cores and the valve body.

[0074] Currently, judging by market developments, thermal management systems are widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric vehicles, as well as in military equipment and aerospace. As the application areas of thermal management systems continue to expand, market demand for them is also growing.

[0075] Taking a vehicle as an example, please refer to Figure 1, which is a structural diagram of an embodiment of a vehicle of the present application. The vehicle can be a fuel vehicle, a gas vehicle or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. The interior of the vehicle is provided with a thermal management system 1, a power mechanism 2, and a battery 3. The battery 3 can be used to power the vehicle. For example, the battery 3 can be used as the operating power supply of the vehicle. The vehicle may also include a vehicle controller 31, which is used to control the battery 3 to supply power to the power mechanism 2, etc., for example, for the starting, navigation and working power requirements of the vehicle during driving. The battery 3 can not only be used as the operating power supply of the vehicle, but also as the driving power supply of the vehicle, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle. The thermal management system 1 can be used not only for thermal management of the battery 3 of the vehicle, but also for thermal management of the power mechanism 2, air-conditioning system, etc. of the vehicle, without specific limitation.

[0076] For example, as shown in FIG2 , a thermal management system 1 for an electric vehicle may include a controller 11, a cooling mechanism 12, a heating mechanism 13, and a multi-way valve 14. The cooling mechanism 12, the heating mechanism 13, the multi-way valve 14, the power mechanism 2, and the battery 3 are connected via pipelines. The multi-way valve 14 connects the different pipelines in the thermal management system 1, which are filled with coolant. The multi-way valve 14 is used to switch the connections between the different pipelines in the thermal management system 1, allowing the coolant to flow through different pipelines or in different directions, thereby switching between different thermal management modes.

[0077] Optionally, the controller 11 may also be integrated into the vehicle controller 31 .

[0078] In the field of vehicle technology, the thermal management system 1 can be applied to electric vehicles / electric vehicles, pure electric vehicles, hybrid vehicles, extended-range electric vehicles, plug-in hybrid vehicles, new energy vehicles, electric buses, electric motorcycles, etc.

[0079] Specifically, the controller 11 refers to a circuit or integrated chip with a logic processing function that can generate corresponding control signals based on thermal management requirements to control the operation of multi-way valves and compressors. The refrigeration mechanism 12 refers to a machine that can remove the heat of the coolant and reduce the coolant temperature, such as a compressor. The heating mechanism 13 refers to a machine that can provide heat to the coolant and increase the coolant temperature, such as a heating component or a compressor. Among them, the heating mechanism 13 can also be a heat exchanger, which is used to absorb the heat in the power mechanism 2 into the coolant to increase the heat of the coolant, etc. The heat exchanger refers to an element or component used to achieve heat energy transfer. The heat exchanger can be an oil cooler, a water cooling mechanism, etc. The power mechanism 2 refers to an element or component used to generate driving force. The power mechanism can convert electrical energy into kinetic energy, that is, driving force; the power mechanism can generate thermal energy in the process of generating driving force, or the power mechanism directly generates thermal energy based on an electrical signal, and the thermal energy is transferred to the element to be heated through the heat exchanger for heating, such as the battery 3.

[0080] The inventors of this application discovered during long-term research that in related technologies, the water channel part of the vehicle's thermal management system uses a combination of multiple three-way water valves and four-way water valves to achieve switching of various flow channel modes. The use of multiple water valves is not only costly, occupies more space, and is heavy, but also requires more water pipes to be connected, making it more difficult to control.

[0081] To address the above issues, please refer to Figures 3 to 5. Figure 3 is a schematic structural diagram of an embodiment of a multi-way valve of the present invention; Figure 4 is an exploded structural diagram of the embodiment of Figure 3; and Figure 5 is a schematic cross-sectional structural diagram of the embodiment of Figure 3. The multi-way valve 14 of this embodiment comprises: a valve body 21 and a plurality of valve cores 22. The valve body 21 is provided with a plurality of accommodating chambers 101, a plurality of interfaces 102, and a through hole 103. The through hole 103 is provided between two adjacent accommodating chambers 101 and is used to connect the two adjacent accommodating chambers 101. The interface 102 is provided on the side wall of the accommodating chamber 101 and is used to connect the corresponding accommodating chamber to an external pipeline. The plurality of valve cores 22 are provided in a one-to-one correspondence with the plurality of accommodating chambers 101. The valve cores 22 are rotatably disposed in the corresponding accommodating chambers 101. The valve cores 22 are provided with a plurality of flow passages 121. At least one of the plurality of valve cores 22 rotates to switch between different combinations of flow passages 121, thereby connecting different combinations of interfaces 102.

[0082] Specifically, the valve body 21 is the main body of the multi-way valve 14 and serves as the carrier of the multi-way valve 14's internal structure. It supports other components of the multi-way valve 14 and can connect to external mechanisms of the multi-way valve 14. It represents the overall size, shape, and structural performance of the multi-way valve 14. The valve body 21 is composed of a top wall, a bottom wall, and side walls connecting the top and bottom walls. The accommodating chamber 101 is defined in the top wall.

[0083] Specifically, the accommodating cavity 101 is a recessed groove formed on the valve body 21 and having a certain accommodating space and an opening. The opening is provided on the top wall. The accommodating space extends from the top wall into the interior of the valve body 21. The rest of the accommodating space is enclosed by the side walls and bottom wall of the valve body 21. The accommodating space is used to accommodate the valve core 22.

[0084] Optionally, the cross section of the accommodating chamber 101 is parallel to the top wall, that is, the shape of the cross section can be circular, which enables the valve core 22 to rotate flexibly therein, and enables the gap between the side wall of the valve core 22 and the inner wall of the accommodating chamber 101 to be reduced, thereby improving the sealing performance of the multi-way valve 14.

[0085] Specifically, the valve core 22 includes a core body and a flow channel 121 disposed in the core body. The flow channel 121 refers to a hollow space disposed inside the core body and used to guide the coolant. Both ends of the flow channel 121 extend and penetrate the side wall of the valve core 22 .

[0086] Optionally, the cross section of the valve core 22 parallel to the top wall, that is, the cross section may be circular, so that the valve core 22 can rotate flexibly in the accommodating cavity 101 and reduce interference.

[0087] The cross-sectional shape of the flow channel 121 can be circular, semicircular, etc., and is not specifically limited.

[0088] When it is necessary to switch the flow mode of the multi-way valve 14, one or more valve cores 22 are controlled to rotate in the corresponding accommodating cavity 101 and rotate around their respective axes based on the required flow mode, so that the relative positions of the multiple valve cores 22 change, so that the different flow channels of the rotated valve core 22 are connected to the through hole 103, so that different combinations of interfaces 102 on the valve body 21 are connected.

[0089] The valve body 21 of the multi-way valve 14 of this embodiment is provided with a plurality of accommodating cavities 101, and a plurality of valve cores 22 are rotatably arranged in the corresponding accommodating cavities 101, respectively, so that a plurality of valve cores 22 can be provided in correspondence with the same valve body 21, thereby realizing the integration of a plurality of valve cores 22, and improving the integration degree, reducing the volume and reducing the thermal management cost; and each valve core 22 is provided with a plurality of flow channels 121, and the rotation of the valve core 22 can switch the flow channels 121 of different combinations to be connected, thereby connecting the interfaces 102 of different combinations on the valve body 21, thereby realizing the switching of multi-flow channel modes.

[0090] In some embodiments, the flow channels 121 of the multiple valve cores 22 are all located in the same plane.

[0091] The flow channels of the multiple valve cores 22 are all located in the same plane, which means that all flow channels 121 do not overlap along the axial direction of the valve core 22. The flow channels 121 of all valve cores 22 are located in the same plane, which can reduce the height of the valve core 22. Furthermore, because the flow channels 121 are used to communicate with the interface 102 on the valve body 21, the interface 102 can be arranged in a single layer on the valve body 21, thereby reducing the height of the valve body 21, facilitating integration with other mechanisms in the thermal management system, and further improving the integration level.

[0092] In some embodiments, the plane where the flow channel of the valve core 22 is located is perpendicular to the axial direction of the valve core 22. In other words, the flow channel 121 in the valve core 22 is arranged in the rotation plane of the valve core 22. This structure can make the ports at both ends of the flow channel 121 (communicated with the interface 102) have the same height, so that all the interfaces 102 on the valve body 21 can be arranged in the rotation plane of the valve core 22, that is, all the interfaces 102 have the same height. This not only avoids the problem of the flow channel 121 not being able to connect well with the interface on the valve body 21 due to the rotation of the valve core 22, but also simplifies the manufacturing process of the valve core 22 and the valve body 21. Moreover, since the flow channel 121 in the valve core 22 has the same height, the height of the valve core 22 can be further shortened; since the height of all the interfaces 102 on the valve body 21 is consistent, the height of the valve body 21 can be further shortened.

[0093] In some embodiments, the multi-way valve 14 further includes a plurality of flow guides 23 disposed outside the valve body 21 , and the plurality of flow guides 23 are disposed in one-to-one correspondence with the plurality of interfaces 102 , and the flow guides 23 are used to connect the corresponding interfaces 102 with external pipelines.

[0094] Specifically, the flow guide 23 refers to a flow guiding component for guiding the coolant flowing through the interface 102 into the external pipeline, or guiding the coolant in the external pipeline into the interface 102 .

[0095] Because the interface 102 is set on the side wall of the valve body 21, it is not convenient to connect it directly to the external pipeline. If it is directly connected to the external pipeline, multiple external pipelines will be arranged around the side of the valve body 21, which is not conducive to the integrated setting of the entire thermal management system. In this embodiment, the guide member 23 is used to extend the interface 102, which can extend the interface 102 to the same plane, so that the entire multi-way valve 14 can be connected to multiple external pipelines on the same plane, which is convenient for the integrated setting of the multi-way valve 14 and the external pipeline. For example, in some application scenarios, a flow plate can be used to realize multiple external pipelines. If the interface 102 is connected to the flow plate, a conduit must be set between the interface 102 and the flow plate. In this embodiment, the guide member 23 can be directly connected to the corresponding pipeline on the flow plate, which has a high degree of integration and a small volume and cost.

[0096] Optionally, the direction of one end of the flow guide 23 facing away from the valve body 21 is opposite to the opening direction of the accommodating cavity 101 .

[0097] In some embodiments, the flow guide 23 and the valve body 21 are integrally formed.

[0098] Specifically, the integral molding arrangement refers to the flow guide member 23 and the valve body 21 being formed into an integral structure through the same manufacturing process. Alternatively, the integral structure of the flow guide member 23 and the valve body 21 can be achieved using a process such as injection molding. Integrally molding the flow guide member 23 and the valve body 21 improves the sealing performance between the flow guide member and the valve body 21, reducing the risk of coolant leakage.

[0099] In some embodiments, the guide member 23 is provided with a guide channel, one end of the guide channel is communicated with the corresponding interface 102 , and the other end of the guide channel extends in a direction opposite to the opening direction of the accommodating cavity 101 .

[0100] Optionally, the guide member 23 is provided with a guide channel and side walls surrounding the guide channel, with both ends of the guide channel extending out of the side walls. One end of the guide channel is connected to the interface 102, and the extension direction of the other end of the guide channel is opposite to the opening direction of the accommodating cavity 101, that is, the other end of the guide channel faces downward.

[0101] A valve cover 24, a driving mechanism 25, etc. are usually provided on the opening side of the accommodating chamber 101 to facilitate the control of the valve core 22 by the driving mechanism 25. Therefore, in this embodiment, the end of the guide channel away from the interface 102 is set in the direction away from the opening of the accommodating chamber 101, which can avoid interference of the guide member 23 on the driving mechanism 25, etc.

[0102] The cross-section of the flow guide channel may be in a circular, semicircular, or other shape, and is not specifically limited thereto.

[0103] In some embodiments, the other end of the diversion channel extends to the plane where the bottom wall of the valve body 21 is located.

[0104] The guide channel is used to connect one end with the external pipeline and extends to the plane where the bottom wall of the valve body 21 is located, so that the end face of the guide channel used to connect the one end with the external pipeline is flush with the outer surface of the bottom wall of the valve body 21, so that the bottom of the entire multi-way valve 14 is flat, and the gap between it and the external pipeline, such as the flow channel plate, can be reduced, thereby improving the stability and integration between the two.

[0105] In some embodiments, the multiple flow channels of the valve core 22 include: a first mode flow channel and / or a second mode flow channel; the first mode flow channel is used to connect two adjacent openings on the side wall of the accommodating chamber 101 corresponding to the valve core 22; the second mode flow channel is used to connect two relatively set openings on the side wall of the accommodating chamber 101 corresponding to the valve core 22; the valve core 22 is rotated so that its first mode flow channel and / or second mode flow channel are respectively connected to the first mode flow channel or the second mode flow channel of the adjacent valve core 22 to form multiple flow channel modes; the opening on the side wall of the accommodating chamber 101 includes an interface 102 and a through hole 103.

[0106] Specifically, a mode flow channel refers to a flow channel in which the connected openings have a certain positional relationship; for example, the first mode flow channel is used to connect two adjacent openings set on the side wall of the accommodating chamber 101, and the flow channel length of the first mode flow channel is shorter; for another example, the second mode flow channel is used to connect two relatively opposite openings set on the side wall of the accommodating chamber 101, and the flow channel length of the second mode flow channel is longer.

[0107] Specifically, the flow path pattern refers to a combination pattern of the flow paths of the plurality of valve cores 22 .

[0108] The valve core 22 of this embodiment is provided with a first mode flow channel and / or a second mode flow channel, which can realize multiple flow channel modes of the multi-way valve 14 and switching between different flow channel modes, and the flow channel lengths of different flow channel modes can be different, which can realize diversion in different directions.

[0109] In some embodiments, the plurality of valve cores 22 include a first valve core (the left valve core in FIG. 4 and FIG. 5 ), and the plurality of flow passages of the first valve core include two first mode flow passages and one second mode flow passage.

[0110] In this embodiment, two first mode flow channels and one second mode flow channel are set for the first valve core, and the second mode flow channel is set between the two first mode flow channels. This structure can not only realize three flow channels, but also make the flow channels compactly arranged and reduce the volume of the first valve core.

[0111] In some embodiments, the plurality of valve cores 22 include a first valve core (the valve core on the left in Figures 4 and 5 ), wherein the plurality of flow passages of the first valve core include two first mode flow passages and one second mode flow passage. The plurality of valve cores 22 also include a second valve core (the valve core on the right in Figures 4 and 5 ), wherein the plurality of flow passages of the second valve core include two first mode flow passages and one second mode flow passage.

[0112] In this embodiment, two first-mode flow channels and one second-mode flow channel are provided for the first valve core, with the second-mode flow channel provided between the two first-mode flow channels. This structure not only realizes three flow channels, but also enables a compact flow channel layout, reducing the volume of the first valve core. In this embodiment, two first-mode flow channels and one second-mode flow channel are provided for the second valve core, with the second-mode flow channel provided between the two first-mode flow channels. This structure not only realizes three flow channels, but also enables a compact flow channel layout, reducing the volume of the second valve core.

[0113] The second valve core and the first valve core adopt the same flow channel structure, which can simplify the process, simplify the control circuit and control logic in the drive mechanism 25, and is conducive to further reducing the volume.

[0114] Among them, the two first mode flow channels and one second mode flow channel of the first valve core respectively form the first flow channel mode, the second flow channel mode and the third flow channel mode with the one first mode flow channel of the second valve core, the two first mode flow channels and one second mode flow channel of the first valve core respectively form the fourth flow channel mode, the fifth flow channel mode and the sixth flow channel mode with the other first mode flow channel of the second valve core, and the two first mode flow channels and one second mode flow channel of the first valve core respectively form the seventh flow channel mode, the eighth flow channel mode and the ninth flow channel mode with the second mode flow channel of the second valve core.

[0115] This embodiment integrates two six-way valve cores 12 (i.e., a first valve core and a second valve core) with identical flow path structures within the valve body 21 to achieve a ten-way multi-way valve 14 having nine flow path modes. Specifically, as shown in Figures 6 to 14 , for ease of description, the ten ports 102 of the valve body 21 may be labeled 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10, respectively.

[0116] In the first flow channel mode, the first mode flow channel of the first valve core is connected to a first mode flow channel of the second valve core through the through hole 103 to connect the interfaces 102 labeled 5 and 10, as shown in Figure 6; the second valve core is controlled to rotate clockwise to switch the multi-way valve 14 to the seventh flow channel mode.

In the ninth flow channel mode, the second mode flow channel of the first valve core is connected to the second mode flow channel of the second valve core through the through hole 103. The mode flow channel is connected to conduct the interfaces 102 labeled 3 and 8, as shown in Figure 10; the second valve core is controlled to continue to rotate counterclockwise to switch the multi-way valve 14 to the third flow channel mode. In the third flow channel mode, the second mode flow channel of the first valve core is connected with the above-mentioned first mode flow channel of the second valve core through the through hole 103 to conduct the interfaces 102 labeled 3 and 10, as shown in Figure 11; the first valve core is controlled to rotate clockwise to switch the multi-way valve 14 to the second flow channel mode. In the second flow channel mode, the other first mode flow channel of the first valve core is connected with the first mode flow channel of the second valve core through the through hole 103 to conduct the interfaces 102 labeled 3 and 10, as shown in Figure 11. 0 is connected, as shown in Figure 12; the second valve core is controlled to rotate clockwise to switch the multi-way valve 14 to the eighth flow channel mode. In the eighth flow channel mode, the above-mentioned other first mode flow channel of the first valve core is connected with the second mode flow channel of the second valve core through the through hole 103 to connect the interfaces 102 numbered 1 and 8, as shown in Figure 13; the second valve core is controlled to rotate clockwise to switch the multi-way valve to the fifth flow channel mode. In the fifth flow channel mode, the above-mentioned other fifth mode flow channel of the first valve core is connected with the other first mode flow channel of the second valve core through the through hole 103 to connect the interfaces 102 numbered 1 and 6, as shown in Figure 14.

[0117] In some embodiments, the plurality of valve cores 22 include a first valve core (the left valve core in FIG15 ), wherein the plurality of flow passages of the first valve core include two first mode flow passages and one second mode flow passage. The plurality of valve cores 22 also include a second valve core (the right valve core in FIG15 ), wherein the plurality of flow passages of the second valve core include three first mode flow passages.

[0118] In this embodiment, the first valve core is provided with two first-mode flow channels and one second-mode flow channel, with the second-mode flow channel disposed between the two first-mode flow channels. This structure not only provides three flow channels but also enables a compact flow channel layout, reducing the volume of the first valve core. The second valve core is provided with three flow channels, each of which is used to connect two adjacent openings on the side wall of the accommodating chamber 101, ensuring that the communication mode of the interface 102 implemented by the second valve core is the same.

[0119] As shown in Figure 15, the first valve core of this embodiment is provided with two first-mode flow channels and one second-mode flow channel, while the second valve core is provided with three first-mode flow channels. The two first-mode flow channels and one second-mode flow channel of the first valve core are freely combined with the three first-mode flow channels of the second valve core to form nine different flow channel patterns. This embodiment achieves a ten-way multi-way valve 14 with nine flow channel patterns by integrating two six-way valve cores 22 (i.e., the first valve core and the second valve core) with different flow channel structures within the valve body 21.

[0120] In some embodiments, as shown in Figure 16, multiple valve cores 22 include a first valve core (such as the valve core on the left in Figure 16) and a second valve core (such as the valve core on the right in Figure 16), and the multiple flow channels of the first valve core include: three second mode flow channels; the multiple flow channels of the second valve core include: three second mode flow channels; wherein, the three second mode flow channels of the first valve core are freely combined with the three second mode flow channels of the second valve core to form nine different flow channel modes.

[0121] In this embodiment, two valve cores 22 of a six-way valve (ie, a first valve core and a second valve core) with the same flow channel structure are integrated in the valve body 21 to realize a ten-way valve with nine flow channel modes.

[0123] The first valve core and the second valve core adopt three different flow paths, which can improve the flexibility of the flow path length and the position of the interface 102.

[0124] In some embodiments, as shown in Figure 17, the multiple flow channels of the first valve core include two first mode flow channels and one second mode flow channel, and the multiple flow channels of the second valve core include one third mode flow channel and one second mode flow channel; the two first mode flow channels and one second mode flow channel of the first valve core are freely combined with one third mode flow channel and one second mode flow channel of the second valve core respectively to form six different flow channel modes.

[0125] In this embodiment, the first valve core is provided with two first-mode flow channels and one second-mode flow channel, and the second-mode flow channel is provided in the two first-mode flow channels. This structure not only realizes three flow channels, but also enables a compact flow channel layout and reduces the volume of the second valve core. In this embodiment, by integrating a first valve core of a six-way valve and a second valve core of a four-way valve within the valve body 21, an eight-way multi-way valve 14 with six flow channel modes is realized.

[0126] In some embodiments, as shown in Figure 18, the multiple flow channels of the first valve core include two first mode flow channels and one second mode flow channel, and the multiple flow channels of the second valve core include two third mode flow channels; the two first mode flow channels and one second mode flow channel of the first valve core are freely combined with the two third mode flow channels of the second valve core to form six different flow channel modes.

[0127] In this embodiment, the first valve core is provided with two first-mode flow channels and one second-mode flow channel, and the second-mode flow channel is provided in the two first-mode flow channels. This structure not only realizes three flow channels but also enables a compact flow channel layout, reducing the volume of the second valve core. In this embodiment, the second valve core is provided with two third-mode flow channels, which can simplify the structure of the second valve core. In this embodiment, by integrating a first valve core of a six-way valve and a second valve core of a four-way valve within the valve body 21, it can realize an eight-way multi-way valve 14 with six flow channel modes.

[0128] In some specific embodiments, multiple flow channels are spaced apart to prevent interference between the flow channels and enable separate control of the multiple flow channels.

[0129] In some embodiments, referring to FIG. 3 and FIG. 4 , the multi-way valve 14 further includes a valve cover 24 disposed on the valve body 21 for sealing the plurality of valve cores 22 in the corresponding accommodating chambers 101 .

[0130] Specifically, the valve cover 24 refers to a structural member used to cover the valve body 21 and to seal the accommodating cavity 101. The valve cover 24 can be provided independently of the valve body 21.

[0131] In other embodiments, the valve cover can also be integrated with the valve body, and the valve cover can also form a common connection surface with the valve body before the valve core and other components are installed into the valve body. When the accommodating cavity needs to be sealed, the valve cover is replaced with the valve body.

[0132] The valve cover 24 can seal the multiple accommodating cavities 101 opened on the valve body 21, which can not only prevent the fluid in the valve core 22 from leaking from the accommodating cavity 101 (except from the interface 102 and the through hole 103), but also prevent fluid leakage between the accommodating cavities 101.

[0133] In some embodiments, the multi-way valve 14 further includes a driving mechanism 25 , which is connected to the plurality of valve cores 22 respectively, and is used to drive the plurality of valve cores 22 to rotate respectively.

[0134] Specifically, the drive mechanism 25 refers to an element or assembly for generating a driving force. The drive mechanism 25 can convert electrical energy into kinetic energy to provide a driving force for the valve core 22. Optionally, the valve core 22 further includes a rotating shaft, one end of which is fixedly connected to the core body, and the other end of the rotating shaft is connected to the drive mechanism 25, for transmitting the driving force generated by the drive mechanism 25 to the valve core 22.

[0135] This embodiment utilizes the driving mechanism 25 to drive the valve core 22 , thereby improving the automated control of the multi-way valve 14 .

[0136] In some embodiments, the driving mechanism 25 includes: multiple driving members, a shell and a driving controller; wherein, the multiple driving members are arranged in a one-to-one correspondence with the multiple valve cores 22, and the driving members are connected to the corresponding valve cores 22 for driving the valve cores 22 to rotate; the shell is provided with a signal interface 251, the shell is arranged on the valve body 21, and the driving member is installed in the shell; the driving controller is installed in the shell and connected to the driving member, for controlling the driving member to generate a driving force to drive the valve core 22 to rotate; the driving controller obtains an electrical signal through the signal interface, and the driving controller generates a control signal to control the driving member based on the electrical signal.

[0137] Optionally, the driving component may be a motor, etc.; the driving controller may be an inverter, etc.

[0138] Different driving members are used to drive the valve core 22 to rotate to corresponding positions to achieve various flow modes. The housing is used to protect the driving member, driving controller, etc.

[0139] Optionally, the same drive controller may be used to control multiple drive components to achieve an integrated arrangement of the drive mechanism 25 .

[0140] Optionally, a connector may be provided at the signal interface for plugging in an external wiring harness and connecting the external wiring harness to the driving component.

[0141] In some embodiments, the multi-way valve 14 further includes a plurality of seals 26 , which are arranged one-to-one corresponding to the plurality of accommodating cavities 101 , and the seals 26 are arranged between the corresponding valve core 22 and the valve body 21 to ensure sealed communication between the valve body 21 and the valve core 22 .

[0142] In this embodiment, a sealing gasket is provided between the valve core 22 and the valve body 21 to prevent fluid leakage.

[0143] The sealing member 26 is provided with an opening that is in communication with and corresponds to the interface 102 and the through hole 103 on the side wall of the valve body 21 , so that the valve core 22 and the valve body 21 are in communication.

[0144] In a specific embodiment, the multi-way valve 14 includes: a valve body 21 and two valve cores 22, the valve body 21 is provided with two accommodating chambers 101, ten interfaces 102 and a through hole 103; wherein, the through hole 103 is provided between the two accommodating chambers 101, and the through hole 103 is used to connect the two accommodating chambers 101, and ten interfaces 102 are provided on the side wall of the accommodating chamber 101, and the interfaces 102 are used to connect the corresponding accommodating chamber with an external pipeline; the two valve cores 22 are arranged in a one-to-one correspondence with the two accommodating chambers 101, and the valve cores 22 are rotatably arranged in the corresponding accommodating chambers 101, and the valve cores 22 are provided with three flow channels 121; at least one of the two valve cores 22 rotates to switch different combinations of flow channels 121 to connect, so that different combinations of interfaces 102 are conductive; wherein, the plane where the flow channel of the valve core 22 is located is perpendicular to the axial direction of the valve core 22.

[0145] This embodiment integrates two six-way valve cores 22 in the valve body 21 to realize a ten-way multi-way valve 14 with nine flow path modes. The nine flow path modes of the two valve cores 22 can be found above.

[0146] The multi-way valve 14 of this embodiment realizes the integration of two valve cores 22, which can improve the integration level, reduce the volume and reduce the thermal management cost; and each valve core 22 is provided with three flow channels 121, and the rotation of the valve core 22 can switch the flow channels 121 of different combinations to be connected, thereby connecting the interfaces 102 of different combinations on the valve body 21, so that the switching of multi-channel modes can be realized; further, because the flow channels 121 in the valve core 22 are consistent in height, the height of the valve core 22 can be further shortened; because the height of all interfaces 102 on the valve body 21 are consistent, the height of the valve body 21 can be further shortened, and because the flow channels 121 are used to connect the interfaces 102 on the valve body 21, the single-layer setting of the interfaces 102 on the valve body 21 can be realized, thereby reducing the height of the valve body 21, facilitating the integrated setting with other mechanisms in the thermal management system, and further improving the integration level.

[0147] Furthermore, the multi-way valve 14 also includes a plurality of guide members 23, which are arranged outside the valve body 21, and the plurality of guide members 23 are arranged in one-to-one correspondence with the plurality of interfaces 102, and the guide members 23 are used to connect the corresponding interfaces 102 with the external pipeline; the guide members 23 and the valve body 21 are integrally formed; the guide members 23 are provided with a guide channel, one end of the guide channel is connected to the corresponding interface, and the extension direction of the other end of the guide channel is opposite to the opening direction of the accommodating cavity 101.

[0148] This embodiment allows the flow guide 23 to be directly connected to the corresponding pipeline on the flow channel plate, achieving high integration, small size, and low cost. Furthermore, the end of the flow channel facing away from the interface 102 is positioned away from the opening of the accommodating chamber 101, thereby preventing the flow guide 23 from interfering with the drive mechanism 25 and the like. The integral molding of the flow guide 23 with the valve body 21 improves the sealing performance between the flow guide 23 and the valve body 21, reducing the risk of coolant leakage.

[0149] The other end of the guide channel extends to the plane where the bottom wall of the valve body 21 is located, which can reduce the gap between it and the external pipeline, such as the flow channel plate, thereby improving the stability and integration between the two.

[0150] The multi-way valve 14 further includes a driving mechanism 25 , which is connected to the plurality of valve cores 22 respectively, and is used to drive the plurality of valve cores 22 to rotate respectively, thereby realizing automatic control of the multi-way valve 14 .

[0151] The valve core 22 also includes a rotating shaft, one end of which is fixedly connected to the core body, and the other end of which is connected to the driving mechanism 25 for transmitting the driving force generated by the driving mechanism 25 to the valve core 22.

[0152] Furthermore, the driving mechanism 25 includes: multiple driving members, a shell and a driving controller; wherein, the multiple driving members are arranged in a one-to-one correspondence with the multiple valve cores 22, and the driving members are connected to the corresponding valve cores 22 for driving the valve cores 22 to rotate; the shell is provided with a signal interface 251, the shell is arranged on the valve body 21, and the driving members are installed in the shell; the driving controller is installed in the shell and connected to the driving member, for controlling the driving member to generate a driving force to drive the valve core 22 to rotate; the driving controller obtains an electrical signal through the signal interface, and generates a control signal for controlling the driving member based on the electrical signal.

[0153] Furthermore, the multi-way valve 14 also includes multiple seals 26, which are arranged one-to-one corresponding to the multiple accommodating cavities 101. The seals 26 are arranged between the corresponding valve cores 22 and valve bodies 21 to ensure that the valve bodies 21 and the valve cores 22 are sealed and connected to prevent fluid leakage.

[0154] The driving mechanism 25 may include a transmission, etc., for adjusting the rotation speed of the valve core 22.

[0155] Optionally, the drive mechanism 25 is arranged on the valve cover 24, specifically on the side of the valve cover 24 facing away from the valve body 21, so as to facilitate the connection between the drive mechanism 25 and the controller 11 and reduce wiring; and the drive mechanism 25 and the guide member 23 are respectively located on the opposite sides of the valve body 21, which can avoid interference between the guide member 23 and the drive mechanism 25.
