[0044] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0045] The valve core, multi-way valve, thermal management system and vehicle provided in the embodiments of the present application are described in detail below with reference to specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0046] like Figure 1 and Figure 2As shown, the valve core according to some embodiments of the present application includes a valve core body 20, and the valve core body 20 is provided with a plurality of flow areas 21 spaced apart along the circumferential direction, and each flow area 21 is provided with at least one flow channel 22; the valve core body 20 is suitable for rotating with the external valve body 1 so that the flow channels 22 in different flow areas 21 are connected to the docking port 13 on the valve body 1.

[0047] In the embodiment of the present application, the valve core 2 includes a valve core body 20, which is provided with a plurality of flow areas 21 spaced apart along the circumference. Each flow area 21 is provided with at least one flow channel 22. The valve core body 20 is adapted to rotate with the external valve body 1 so that the flow channels 22 in different flow areas 21 communicate with the docking port 13 on the valve body 1. Thus, by integrating multiple flow areas 21 on the valve core body 20, the overall size of the valve core 2 is reduced. At the same time, different flow channels 22 are provided in different flow areas 21. Thus, when the valve core 2 is rotated relative to the valve body 1, the flow channels 22 in different flow areas 21 can communicate with at least part of the docking port 13 on the valve body 1. Thus, the simple structure of the valve core 2 can satisfy the complex communication relationship between external pipelines, shorten the pipeline length, and reduce flow resistance loss.

[0048] It should be explained that in order to enable the valve core 2 to rotate with the valve body 1, the valve core 2 is set to a cylindrical shape, thereby facilitating the formation of a rotating connection and facilitating the provision of multiple flow areas 21 on the valve core 2. The circumferential direction of the cylindrical outer surface of the valve core 2 is the circumferential direction of the valve core 2, the axial direction of the cylinder is the axial direction X of the valve core 2, and the radial direction of the cylinder is the radial direction of the valve core 2.

[0049] In specific applications, the number of flow areas 21 and the number of docking ports 13 can be set according to actual needs to meet different modes of the thermal management system. Those skilled in the art can set them according to needs, and this application does not impose any restrictions on this.

[0050] It should be explained that which docking port 13 the flow channel 22 is connected to depends on the structure and shape of the flow channel 22 . Thus, by adjusting the structure and shape of the flow channel 22 , different communication channels can be formed to correspond to the connections between different external pipelines.

[0051] It should be explained that the specific shape of the flow channel 22 can be set to: "L-shaped", "fan-shaped", "straight-line", "S-shaped", "U-shaped", etc. Technical personnel in this field can set it according to actual needs, and this application does not impose any restrictions on this.

[0052] It can be understood that the valve core 2 rotates relative to the external valve body 1, so that the flow channels 22 of different flow areas 21 are connected to different docking ports 13 to form different connecting channels, thereby corresponding to different connecting modes of the multi-way valve to match the different working conditions of the thermal management system. The specific connecting relationship can be set by technical personnel in this field according to actual needs, and this application does not impose any restrictions on this.

[0053] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, in some embodiments of the present application, the multiple circulation areas 21 include at least one preset circulation area, in which at least two openings 200 radially opened along the valve core body 20 are provided, and a partition 23 is arranged between the two openings 200, and a through hole 24 is provided in the partition 23, and the through hole 24 connects the two openings 200 to form a flow channel 22, the two openings 200 are suitable for communicating with the two docking ports 13 on the valve body 1, and the partition 23 is suitable for blocking the area between the two docking ports 13 in the valve body 1.

[0054] In an embodiment of the present application, the multiple circulation areas 21 include at least one preset circulation area, and the preset circulation area is provided with at least two openings 200 radially opened along the valve core 2, and a partition 23 arranged between the two openings 200. A through hole 24 is provided in the partition 23, thereby connecting the two openings to form a flow channel 22, which can connect the two spaced-apart docking ports 13 on the valve body 1, enriching the form of the flow channel 22, thereby realizing the connection between the external pipelines connected to the two spaced-apart docking ports 13 on the valve body 1 through a simple structure on the valve core 2.

[0055] It needs to be explained that each docking port 13 is connected to an external pipeline, and there may be a need for communication between each external pipeline. Therefore, the communication between the two spaced external pipelines is achieved through two openings 200 and a through hole 24 that are spaced apart. The structure is simpler, the flow path is shorter, and the flow resistance is smaller.

[0056] In specific applications, the two openings 200 radially opened along the valve core 2 can be arranged at intervals along the circumferential direction of the valve core 2, or can be arranged at intervals along the axial X direction of the valve core 2. Those skilled in the art can set it according to actual needs, and this application does not impose any restrictions on this.

[0057] It can be understood that the number of openings 200 in the preset circulation area is at least two, specifically, it can be 2, 3, 4, 5, 6, etc. Those skilled in the art can set it according to actual needs, and this application does not impose any restrictions on this.

[0058] Correspondingly, the number of docking ports 13 in the docking area 12 can be specifically set to: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc. Those skilled in the art can set it according to actual needs, and this application does not impose any restrictions on this.

[0059] In specific applications, different docking ports 13 in the docking area 12 can be connected to different pipes in the thermal management system. These pipes are used in different vehicle components, such as: battery pack circulation loop pipes, air conditioning loop pipes, motor loop pipes, water tank pipes, condensate pipes, etc. Those skilled in the art can set them according to actual needs, and this application does not impose any restrictions on this.

[0060] Specifically, in actual use, the docking port 13 is usually configured as a liquid inlet and multiple liquid outlets. Taking the multi-way valve used to switch the coolant pipeline as an example, the multiple docking ports 13 include A docking port, B docking port and C docking port, A docking port is connected to the coolant compressor or communicated with the water tank, B docking port is communicated with the battery pack circulation loop pipeline, and C docking port is communicated with the motor loop pipeline; the multiple circulation areas 21 include D circulation area, D circulation area is provided with E flow channel, when D circulation area cooperates with the docking area 12, E flow channel is respectively communicated with A docking port, B docking port and C docking port, so that the condensate enters the multi-way valve from A docking port, and then enters the battery pack circulation loop pipeline through B docking port, and enters the motor loop pipeline through C docking port, so as to cool the battery pack and motor of the vehicle respectively, realizing "one in and multiple outs".

[0061] In some embodiments of the present application, a plurality of valve cores 2 are provided, and the plurality of valve cores 2 are arranged along their axial direction. Each valve core 2 is provided with a plurality of flow areas 21. Adjacent valve cores 2 can rotate relative to each other or rotate together. Each valve core 2 corresponds to a docking area 12. By rotating the valve core 2 to connect or disconnect the flow channels 22 on adjacent valve cores 2, a plurality of connecting channels are formed between different docking ports 13.

[0062] like Figure 2 and Figure 3 As shown, in some embodiments of the present application, along the axial direction of the valve core 2 , the two openings 200 are spaced apart along the axial direction X of the valve core 2 .

[0063] In the embodiment of the present application, by arranging the two openings 200 at intervals along the axial direction X of the valve core 2, the space occupied by the preset flow area in the circumferential direction of the valve core 2 can be reduced, so that more flow areas 21 can be set on the valve core 2, enriching the types of flow channels 22 integrated on the valve core 2, thereby improving the achievable connection forms.

[0064] It should be explained that the two openings 200 are arranged at intervals along the axial direction X of the valve core 2, so that the preset flow area along the circumferential direction of the valve core 2 can only occupy the width of the opening 200 along the circumferential direction of the valve core 2, thereby making the structure of the preset flow area more compact.

[0065] like Figure 6 As shown, in some embodiments of the present application, the preset circulation area includes a first circulation area 211, and the first circulation area 211 is provided with a first opening 201 and a second opening 202 radially opened along the valve core 2, and a first partition 231 is provided between the first opening 201 and the second opening 202. The first opening 201 and the second opening 202 are arranged at intervals along the axial direction X of the valve core 2, and a first through hole 241 is provided in the first partition 231. The first opening 201 and the second opening 202 are connected through the first through hole 241 to form a first flow channel 221.

[0066] In an embodiment of the present application, a first flow channel 221 is formed by the first opening 201 and the second opening 202 arranged at intervals along the axial direction X of the valve core 2, and a first through hole 241 connecting the first opening 201 and the second opening 202, so that it can be connected to the two docking ports 13 arranged at intervals on the valve body 1, thereby realizing communication between the interval-arranged pipelines, and the docking port between the two docking ports 13 is blocked by the first partition 231.

[0067] In a specific application, the first flow channel 221 is communicated with two spaced-apart docking ports 13 on the valve body 1 , and the first partition 231 blocks the docking port 13 located between the two docking ports 13 to form a communication channel.

The third opening 203 and the fourth opening 204 are connected through the second through hole 242 to form a second flow channel 222.

[0069] In an embodiment of the present application, a second flow channel 222 is formed by the third opening 203 and the fourth opening 204 arranged at intervals along the axial direction X of the valve core 2, and the second through hole 242 connecting the third opening 203 and the fourth opening 204, so that it can be connected to the two docking ports 13 arranged at intervals on the valve body 1, thereby realizing communication between the interval-arranged pipelines, and the docking port between the two docking ports 13 is blocked by the second partition 232.

[0070] In a specific application, the second flow channel 222 is communicated with two spaced-apart docking ports 13 on the valve body 1 , and the second partition 232 blocks the docking port 13 located between the two docking ports 13 to form a communication channel.

[0072] In the embodiment of the present application, a fifth opening 205 and a sixth opening 206 are provided along the axial direction X of the valve core 2, and the fifth opening 205 and the sixth opening 206 are connected to form an L-shaped third flow channel 223, so that when the second flow area 212 is matched with the docking port 13, the third flow channel 223 can connect the two adjacent docking ports 13, and the connecting channel formed with the second flow channel 222 is independent of each other, so that when the second flow area 212 is matched with the valve body 1, two independent connecting channels are formed to meet more connection requirements.

[0073] In a specific application, along the circumferential direction of the valve core 2 , the arc length of the fifth opening 205 is greater than the arc length of the sixth opening 206 , so that the fifth opening 205 and the sixth opening 206 are combined to form an L-shaped third flow channel 223 .

[0077] In the embodiment of the present application, the tenth opening 2010, the eleventh opening 2011, the twelfth opening 2012, and the thirteenth opening 2013 are arranged along the axial direction X of the valve core 2. The tenth opening 2010 communicates with the eleventh opening 2011 to form an L-shaped fifth flow channel 225, and the twelfth opening 2012 communicates with the thirteenth opening 2013 to form an L-shaped sixth flow channel 226. The fifth flow channel 225 and the sixth flow channel 226 are independent of each other. In this way, two independent L-shaped fifth flow channels 225 and L-shaped sixth flow channels 226 are formed in the fourth circulation area 214. When the fourth circulation area 214 cooperates with the docking port 13 on the valve body 1, the fifth flow channel 225 forms one communication channel with the docking port 13, and the sixth flow channel 226 forms another communication channel with the docking port 13, thereby meeting different external pipeline connection requirements.

[0078] like Figure 10As shown, in some embodiments of the present application, the multiple circulation areas 21 also include a fifth circulation area 215, and the fifth circulation area 215 is provided with a fourteenth opening 2014, a fifteenth opening 2015, a sixteenth opening 2016, a seventeenth opening 2017 and an eighteenth opening 2018 opened along the radial direction of the valve core 2, the fourteenth opening 2014, the fifteenth opening 2015, the sixteenth opening 2016 and the eighteenth opening 2018 are arranged along the axial direction X of the valve core 2, and the seventeenth opening 2017 and the sixteenth opening 2016 are arranged at intervals along the circumferential direction of the valve core 2; the fourteenth opening 2014, the fifteenth opening 2015 and the sixteenth opening 2016 are connected to form a seventh flow channel 227, the seventeenth opening 2017 and the eighteenth opening 2018 are connected to form an L-shaped eighth flow channel 228, and the seventh flow channel 227 and the eighth flow channel 228 are independent of each other.

The fourteenth opening 2014, the fifteenth opening 2015, and the sixteenth opening 2016 are connected to form a seventh flow channel 227, and the seventeenth opening 2017 and the eighteenth opening 2018 are connected to form an L-shaped eighth flow channel 228. The seventh flow channel 227 and the eighth flow channel 228 are independent of each other. In this way, two independent seventh flow channels 227 and an L-shaped eighth flow channel 228 are formed in the fifth flow area 215. When the fifth flow area 215 cooperates with the docking port 13 on the valve body 1, the seventh flow channel 227 forms a communication channel with the docking port 13, and the L-shaped eighth flow channel 228 forms another communication channel with the docking port 13, thereby meeting different external pipeline connection requirements.

[0080] It should be explained that, along the circumferential direction of the valve core 2 , the arc length of the eighteenth opening 2018 is greater than the arc length of the seventeenth opening 2017 , so that when the seventeenth opening 2017 is connected to the eighteenth opening 2018 , an L-shaped eighth flow channel 228 is formed.

A sealing block 26 is provided between two adjacent partitions 25, and a flow channel 22 is provided through the sealing block 26. When the flow area 21 is engaged with the valve body 1, the flow channel 22 can communicate with some of the docking ports 13, while the sealing block 26 can block the remaining docking ports 13. This makes the structure of the valve core 2 simpler and more compact, and can achieve a variety of communication modes of the docking ports 13.

[0083] In specific applications, the valve core body 20, the partition 25 and the sealing block 26 can be an integrally formed structure or a split-formed structure. Those skilled in the art can make a choice according to their needs, and this application does not impose any restrictions on this.

[0084] In some embodiments of the present application, the thickness of the partition 25 satisfies and is greater than or equal to 1.5 mm.

[0085] In the embodiment of the present application, the thickness of the partition 25 is greater than or equal to 1.5 mm, so as to meet the requirements of structural strength and sealing.

[0087] like Figure 1 、 Figure 2 、 Figure 11 and Figure 12 As shown, in some embodiments of the present application, a multi-way valve is proposed, including a valve body 1 and a valve core 2 as described in any of the above embodiments, the valve body 1 is provided with a accommodating cavity 11, the valve core 2 is arranged in the accommodating cavity 11, and is rotatably connected to the valve body 1; the inner wall of the valve body 1 is provided with a docking area 12, and the docking area 12 is provided with a plurality of docking ports 13, and the docking ports 13 are suitable for communicating with external pipelines; the valve core 2 can be rotated relative to the valve body 1 to adjust the flow area 21 that cooperates with the docking area 12, and to make the flow channel 22 in the flow area 21 communicate with at least part of the docking port 13.

[0088] In an embodiment of the present application, the valve core 2 can rotate relative to the valve body 1, so that different flow areas 21 can be adjusted to cooperate with the docking area 12 on the valve body 1, so that different flow channels 22 in different flow areas 21 are connected to at least part of the docking interface 13, so that each flow area 21 can enable different external pipelines to form a connecting relationship through the multi-way valve, thereby meeting different needs.

[0089] In a specific application, the valve core 2 is arranged in multiple flow areas 21 at intervals along the circumferential direction, and each flow area 21 is provided with at least one flow channel 22. The flow channel 22 has an opening along the radial direction of the valve core 2, so that when the corresponding flow area 21 cooperates with the docking area 12 on the valve body 1, that is, when the valve core 2 rotates to the position corresponding to the flow area 21 and the docking area 12, the flow channel 22 is connected with the corresponding docking port 13 to form a connecting channel.

[0090] It can be understood that the number of circulation areas 21 and the number of docking ports 13 can be set according to actual needs to meet different modes of the thermal management system. Those skilled in the art can set them according to needs, and this application does not impose any restrictions on this.

[0091] It can be understood that the multiple flow areas 21 can be a groove structure formed on the surface of the valve core 2, or can be formed by multiple partitions connected to the surface of the valve core 2. Those skilled in the art can set it according to needs, and this application does not impose any restrictions on this.

[0092] like Figure 1 As shown, in some embodiments of the present application, the multi-way valve further includes a driving member 3 , which is connected to the valve core 2 and is used to drive the valve core 2 to rotate to adjust the flow area 21 that cooperates with the docking area 12 .

[0093] In the embodiment of the present application, by providing a driving member 3, the valve core 2 can be driven to rotate so that different flow areas 21 on the valve core 2 cooperate with the docking area 12, thereby improving the convenience of the multi-way valve.

[0094] In specific applications, the driving member 3 may be powered by hydraulic drive, motor drive, etc. Those skilled in the art may configure the driving member 3 according to their needs, and this application does not impose any restrictions on this.

[0095] like Figure 11 and Figure 12 As shown, in some embodiments of the present application, the plurality of docking interfaces 13 include at least: a first docking interface 131, a second docking interface 132, a third docking interface 133, a fourth docking interface 134, a fifth docking interface 135 and a sixth docking interface 136. Along the axial direction X of the valve core 2, the first docking interface 131, the second docking interface 132, the third docking interface 133 and the fourth docking interface 134 are spaced apart in sequence; along the circumferential direction of the valve core 2, the fifth docking interface 135 is spaced apart from the third docking interface 133, and the sixth docking interface 136 is spaced apart from the second docking interface 132.

[0097] It needs to be explained that, Figure 11 As shown, one side of the valve body 1 is provided with connecting holes respectively connected to multiple docking ports 13, and the outlets or inlets of the multiple connecting holes are on the same plane, so as to facilitate the integrated arrangement of external pipelines, improve space utilization, and facilitate the design layout of integrated modules.

[0098] like Figure 6 and Figure 12 As shown, in some embodiments of the present application, when the first circulation area 211 cooperates with the docking area 12 on the valve body 1, the first flow channel 221 is connected to the first docking port 131, the third docking port 133 and the fifth docking port 135, that is, the first docking port 131, the third docking port 133 and the fifth docking port 135 form a connecting channel through the first opening 201, the second opening 202 and the first through hole 241, the second docking port 132 and the sixth docking port 136 are blocked by the first partition 231, and the fourth docking port 134 is blocked by the sealing block 26, thereby forming the first connecting mode of the multi-way valve.

[0099] like Figure 7 and Figure 12 As shown, in some embodiments of the present application, when the second circulation area 212 cooperates with the docking area 12 on the valve body 1, the second flow channel 222 is connected to the second docking port 132 and the fourth docking port 134, and the third flow channel 223 is connected to the first docking port 131 and the sixth docking port 136; that is, the first docking port 131 and the sixth docking port 136 form a connecting channel through the fifth opening 205 and the sixth opening 206 and the second through hole 242, the second docking port 132 and the fourth docking port 134 form another connecting channel, the third docking port 133 is blocked by the second partition 232, and the fifth docking port 135 is blocked by the sealing block 26, thereby forming the second connecting mode of the multi-way valve.

[0100] like Figure 8 and Figure 12As shown, in some embodiments of the present application, when the third flow area 213 cooperates with the docking area 12 on the valve body 1, the fourth flow channel 224 is connected to the first docking port 131, the second docking port 132 and the fourth docking port 134, that is, the first docking port 131, the second docking port 132 and the fourth docking port 134 form a connecting channel through the seventh opening 207, the eighth opening 208 and the ninth opening 209 and the third through hole 243, the third docking port 133 is blocked by the third partition 233, and the fifth docking port 135 and the sixth docking port 136 are blocked by the sealing block 26, thereby forming the third connecting mode of the multi-way valve.

[0101] like Figure 9 and Figure 12 As shown, in some embodiments of the present application, when the fourth circulation area 214 cooperates with the docking area 12 on the valve body 1, the fifth flow channel 225 is connected to the first docking port 131 and the second docking port 132, and the sixth flow channel 226 is connected to the third docking port 133 and the fourth docking port 134; that is, the first docking port 131 and the second docking port 132 are connected through the tenth opening 2010 and the eleventh opening 2011, the third docking port 133 and the fourth docking port 134 are connected through the twelfth opening 2012 and the thirteenth opening 2013, and the fifth docking port 135 and the sixth docking port 136 are blocked by the sealing block 26, thereby forming the fourth communication mode of the multi-way valve.

[0102] like Figure 10 and Figure 12 As shown, in some embodiments of the present application, when the fifth circulation area 215 cooperates with the docking area 12 on the valve body 1, the seventh flow channel 227 is connected to the first docking port 131, the second docking port 132 and the third docking port 133, and the eighth flow channel 228 is connected to the fourth docking port 134 and the fifth docking port 135; that is, the first docking port 131, the second docking port 132 and the third docking port 133 are connected through the fourteenth opening 2014, the fifteenth opening 2015 and the sixteenth opening 2016, the fourth docking port 134 and the fifth docking port 135 are connected through the seventeenth opening 2017 and the eighteenth opening 2018, and the sixth docking port 136 is blocked by the sealing block 26, thereby forming the fifth communication mode of the multi-way valve.

[0103] It can be understood from the above embodiments that the multi-way valve of the present application has at least five communication modes, as follows:

[0104] First connection mode: the first pair of interfaces 131, the third pair of interfaces 133 and the fifth pair of interfaces 135 are connected;

[0105] Second communication mode: the first pair of interfaces 131 and the sixth pair of interfaces 136 are connected, and the second pair of interfaces 132 and the fourth pair of interfaces 134 are connected;

[0106] Third communication mode: the first pair of interfaces 131, the second pair of interfaces 132 and the fourth pair of interfaces 134 are connected;

[0107] Fourth communication mode: the first pair of interfaces 131 and the second pair of interfaces 132 are connected, and the third pair of interfaces 133 and the fourth pair of interfaces 134 are connected;

[0108] Fifth communication mode: the first pair of interfaces 131 , the second pair of interfaces 132 and the third pair of interfaces 133 are in communication, and the fourth pair of interfaces 134 and the fifth pair of interfaces 135 are in communication.

[0109] In this way, the multi-way valve can adapt to different modes of the thermal management system. It should be noted that in each communication mode, the required docking port 13 is connected to the flow channel 22, while the remaining docking ports 13 that do not need to be connected are blocked by the partition 23 or the sealing block 26 on the valve core 2. This ensures that only the communication channels required for each communication mode are connected, matching the pipeline switching of the thermal management system.

[0110] Of course, the number of communication modes of the multi-way valve of the present application corresponds to the number of flow areas 21 , that is, each flow area 21 forms a communication mode when matched with the docking area 12 .

[0111] like Figure 11 and Figure 12 As shown, in some embodiments of the present application, along the circumferential direction of the valve core 2 , the size of the first docking port 131 is larger than the size of the second docking port 132 , the third docking port 133 , the fifth docking port 135 or the sixth docking port 136 .

[0112] In the embodiment of the present application, along the circumferential direction of the valve core 2, the size of the first docking port 131 is larger than the size of the second docking port 132, the third docking port 133, the fifth docking port 135 or the sixth docking port 136. In this way, when the first docking port 131 is connected with multiple docking ports 13, a "one-inlet and multiple-outlet" connecting channel can be formed. Moreover, since the size of the first docking port 131 is larger than the other four docking ports 13, the flow rate will not fluctuate too much when the liquid flows, thereby improving the flow stability of the liquid.

[0113] It needs to be explained that along the circumferential direction of the valve core 2, the size of the first docking interface 131 is the arc length of the first docking interface 131 along the circumference of the valve core 2, and the arc length of the first docking interface 131 is greater than the arc length of the second docking interface 132. The same applies to the remaining third docking interface 133, the fifth docking interface 135 or the sixth docking interface 136, and they have the same size relationship.

[0114] like Figure 11 and Figure 12As shown, in some embodiments of the present application, along the circumferential direction of the valve core 2, the size of the fourth docking port 134 is larger than the size of the second docking port 132, the third docking port 133, the fifth docking port 135 or the sixth docking port 136.

[0115] In the embodiment of the present application, along the circumferential direction of the valve core 2, the size of the fourth docking port 134 is larger than the size of the second docking port 132, the third docking port 133, the fifth docking port 135 or the sixth docking port 136. In this way, when the fourth docking port 134 is connected with multiple docking ports 13, a "one-inlet and multiple-outlet" connecting channel can be formed. Moreover, since the size of the fourth docking port 134 is larger than the other four docking ports 13, the flow rate will not fluctuate too much when the liquid flows, thereby improving the flow stability of the liquid.

[0116] It should be noted that the dimension of the fourth docking port 134 along the circumferential direction of the valve core 2 is the arc length of the fourth docking port 134 along the circumference of the valve core 2. The arc length of the fourth docking port 134 is greater than the arc length of the second docking port 132. The same applies to the third docking port 133, the fifth docking port 135, and the sixth docking port 136, which have the same dimensional relationship. This also facilitates the layout of the multiple docking ports 13 on the valve body 1, making the multiple docking ports 13 in the overall docking area 12 more compact and improving the integration of the multi-way valve.

[0117] like Figure 1 and Figure 11 As shown, in some embodiments of the present application, the valve body 1 includes a shell 14 and a valve cover 15, the valve cover 15 is connected to the shell 14 to enclose a accommodating cavity 11, and the docking area 12 is provided on the inner wall of the shell 14; one end of the valve core 2 is rotatably connected to the shell 14, and the other end is rotatably connected to the valve cover 15.

[0119] Specifically, the connection between the housing 14 and the valve cover 15 can be: screw connection, bonding, clamping, etc., and those skilled in the art can set it according to needs, and this application does not impose any restrictions on this.

[0120] like Figure 1 As shown, in some embodiments of the present application, the multi-way valve further includes a first sealing member 4 , which is disposed between the housing 14 and the valve cover 15 .

[0121] In the embodiment of the present application, a first sealing member 4 is provided between the housing 14 and the valve cover 15 to prevent the liquid in the housing 14 from flowing out from the connection, thereby ensuring the sealing of the multi-way valve.

[0122] The first sealing member 4 may be a sealing ring, a sealing gasket, etc. Those skilled in the art may select one according to their needs, and this application does not impose any limitation on this.

[0123] In some embodiments of the present application, the multi-way valve also includes a second seal, which is arranged around the valve core 2 and the housing 14 along the circumferential direction of the valve core 2.

[0125] In the embodiment of the present application, the valve core 2 is rotationally connected to the driving member 3 and the housing 14 through the rotating shaft 5, so that the rotation of the valve core 2 is more stable and reliable, and maintenance is convenient.

[0126] In a specific application, the first mounting hole 27 includes a fixing portion and a positioning portion. The fixing portion is a polygonal hole formed along the circumferential direction of the first mounting hole 27. Correspondingly, a matching polygonal shaft is provided on the rotating shaft 5, so that the rotating shaft 5 can drive the valve core 2 to rotate; the positioning portion is a circular hole, so that the corresponding part of the rotating shaft 5 can pass through and be penetrated into the valve cover 15.

[0127] like Figure 1 、 Figure 11 and Figure 12 As shown, in some embodiments of the present application, a positioning column 141 is provided in the housing 14, and a second mounting hole (not shown in the figure) is provided at one end of the rotating shaft 5 away from the valve cover 15, and the positioning column 141 is rotatably connected to the second mounting hole.

[0128] In an embodiment of the present application, a positioning column 141 is provided in the housing 14, and the positioning column 141 is rotatably connected to the second mounting hole on the rotating shaft 5, thereby ensuring the stability and reliability of the valve core 2 during rotation, and is used to position the valve core 2 and ensure that the valve core 2 rotates coaxially relative to the housing 14, avoiding wear or jamming caused by eccentric rotation.

[0129] In some embodiments of the present application, a thermal management system is proposed, comprising the multi-way valve as described in any of the above embodiments.

[0130] In the embodiment of the present application, the valve core 2 includes a valve core body 20, which is provided with a plurality of flow areas 21 spaced apart along the circumference. Each flow area 21 is provided with at least one flow channel 22. The valve core body 20 is adapted to rotate with the external valve body 1 so that the flow channels 22 in different flow areas 21 communicate with the docking port 13 on the valve body 1. Thus, by integrating multiple flow areas 21 on the valve core body 20, the overall size of the valve core 2 is reduced. At the same time, different flow channels 22 are provided in different flow areas 21. Thus, when the valve core 2 is rotated relative to the valve body 1, the flow channels 22 in different flow areas 21 can communicate with at least part of the docking port 13 on the valve body 1. Thus, the simple structure of the valve core 2 can satisfy the complex communication relationship between external pipelines, shorten the pipeline length, and reduce flow resistance loss.

The valve core body 20 is adapted to rotate with the external valve body 1 so that the flow channels 22 in different flow areas 21 communicate with the docking port 13 on the valve body 1.
