In addition, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.
[0050] In the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0051] Reference is made below Figures 1-9 A multi-way valve 200 according to an embodiment of the present application is described.
[0052] In combination Figures 1 to 3According to the multi-way valve 200 of the embodiment of the present application, the housing 210 is provided with a plurality of valve port rows 211 which are circumferentially spaced apart, each of the valve port rows 211 comprises a plurality of valve ports 2111 which are axially spaced apart, and the valve core 100 is provided with a plurality of flow channel groups which are circumferentially spaced apart, and the valve core 100 is rotatably arranged in the mounting cavity 215 so as to switch the communication between the flow channel groups and the corresponding valve port rows 211 of the housing 210. It can be seen that the flow channel inlets and the flow channel outlets of the flow channel groups are formed on the outer circumferential wall of the valve core 100, so that the flow channel inlets and the flow channel outlets are communicated with the corresponding valve ports 2111, and any one of the flow channel groups can be communicated with the corresponding valve port rows 211 by rotating the valve core 100, so as to switch the multi-way valve 200 to the corresponding communication mode.
[0053] For example, the mounting cavity 215 extending in the axial direction is formed in the housing 210, and one end of the housing 210 in the axial direction is open, the valve core 100 can be mounted into the mounting cavity 215 through the open end of the housing 210, and the valve core 100 can be driven to rotate in the mounting cavity 215.
[0054] For example, the valve ports 2111 extend through the circumferential wall of the mounting cavity 215 in the radial direction (it can also be understood that the valve ports 2111 extend through the housing 210 in the radial direction), and the side of the valve ports 2111 away from the valve core 100 in the radial direction is used to communicate with the external pipeline, when the valve port rows 211 and the flow channel groups are opposite in the radial direction, the valve port rows 211 are communicated with the flow channel groups, and the fluid can flow from the external pipeline into the flow channel groups through the valve ports 2111; by driving the valve core 100 to rotate in the mounting cavity 215, different flow channel groups can be opposite to the valve port rows 211 respectively, so as to switch the flow channel groups communicated with the valve port rows 211, and realize the multiple communication modes of the multi-way valve 200.
[0055] In the embodiment, at least one of the flow channel groups comprises at least one conduction structure 110, the number of the flow channel groups comprising the conduction structure 110 is less than or equal to the total number of the flow channel groups, each of the conduction structures 110 is used to communicate the corresponding valve ports 2111 of the same valve port row 211, and each of the conduction structures 110 comprises a first conduction flow channel 111 and a second conduction flow channel 112 which are spaced apart, the second conduction flow channel 112 is used to communicate two adjacent valve ports 2111, the first conduction flow channel 111 is used to communicate another two valve ports 2111 which are separated from the two valve ports 2111 communicated by the second conduction flow channel 112, and the two valve ports 2111 communicated with the first conduction flow channel 111 and the two valve ports 2111 communicated with the second conduction flow channel 112 belong to the same valve port row 211.
[0056] Specifically, the first and second flow channels 111 and 112 are spaced apart to ensure the independence between the first and second flow channels 111 and 112, and fluid can flow into the first or second flow channel 111 or 112 independently, so that the valve core 100 can define different flow paths for fluid flow, facilitating the realization of different communication states of the multi-way valve 200, i.e., different communication modes of the multi-way valve 200.
[0057] The second flow channel 112 is used to communicate with two valve ports 2111 arranged adjacent in the axial direction in the same valve port row 211, fluid flows into the second flow channel 112 through one of the two valve ports 2111 arranged adjacent in the axial direction, and flows out of the second flow channel 112 through the other valve port 2111. The first flow channel 111 is used to communicate with the valve ports 2111 respectively located on both sides of the two valve ports 2111 communicated by the second flow channel 112 in the axial direction, and fluid can flow into the first flow channel 111 through one of the two valve ports 2111 and flow out of the first flow channel 111 through the other valve port 2111.
[0058] For example, the valve port row 211 corresponding to the flow-through structure 110 can include five valve ports 2111 arranged spaced apart in the axial direction, and the five valve ports 2111 are sequentially named as first port, second port, third port, fourth port and fifth port in the axial direction, and can include the following multiple settings: 1, the second flow channel 112 can communicate the second and third ports, and the first flow channel 111 can communicate the first and fourth ports, or the first flow channel 111 can communicate the first and fifth ports; 2, the second flow channel 112 is used to communicate the third and fourth ports, and the first flow channel 111 is used to communicate the second and fifth ports, or the first flow channel 111 is used to communicate the first and fifth ports. Of course, the valve port row 211 corresponding to the flow-through structure 110 can also be configured to include four valve ports 2111.
[0059] Alternatively, for a single flow channel group including the flow-through structure 110, the flow channel group can include multiple flow-through structures 110, and the multiple flow-through structures 110 can be arranged spaced apart in the circumferential direction, so that the multiple flow-through structures 110 are adapted to be arranged one-to-one corresponding to multiple valve port rows 211, and each flow-through structure 110 can communicate the valve ports 2111 corresponding to the same valve port row 211, thereby realizing one multi-way mode of the multi-way valve 200, at this time different flow-through structures 110 correspond to different valve port rows 211 respectively; or, the multiple flow-through structures 110 of the flow channel group can be arranged spaced apart in the axial direction, so that the multiple flow-through structures 110 are adapted to correspond to the same valve port row 211 respectively; or, the multiple flow-through structures 110 of the flow channel group can be arranged in multiple rows and multiple columns in the circumferential and axial directions. Of course, the flow channel group can also include one flow-through structure 110.
[0060] It can be understood that when at least two groups of the plurality of groups of flow channel groups each include the conductive structure 110, the number and arrangement of the conductive structures 110 of the at least two groups of flow channel groups can be the same or different.
[0061] In the related art, a multi-way valve can achieve fewer communication modes, which cannot meet the use requirements. Especially when the multi-way valve is applied to a complex structure of a thermal management system, in order to ensure that the thermal management system can achieve multiple heat exchange modes, multiple multi-way valves need to be arranged in the thermal management system to switch the communication states of different pipelines of the thermal management system, resulting in that the thermal management system occupies a large space, is inconvenient to control, and has a high production cost.
[0062] The present application improves the space utilization of the valve core 100 by arranging a plurality of groups of flow channel groups on the valve core 100, and increases the flow channel structure on the valve core 100, wherein at least one group of flow channel groups includes at least one conductive structure 110, that is, the structures of the plurality of groups of flow channel groups are different, and a plurality of valve port rows 211 are formed on the shell 210. By switching the communication between the valve port row 211 and the plurality of groups of flow channel groups, multiple communication modes of the multi-way valve 200 are achieved. For the same valve port row 211, by arranging the conductive structure 110, the second conductive flow channel 112 can communicate two adjacent valve ports 2111, and the first conductive flow channel 111 can communicate two valve ports 2111 spaced apart by the two valve ports 2111, so that different valve ports 2111 of the same valve port row 211 are communicated, increasing the applicable scenarios of the multi-way valve 200 and improving the performance of the multi-way valve 200. When the multi-way valve 200 is applied to the thermal management system 300, it is beneficial to reduce the arrangement of the valve body in the thermal management system 300, thereby facilitating the weight reduction and cost reduction of the thermal management system 300, and facilitating the miniaturization design of the thermal management system 300.
[0063] Referring to Figure 1 In the description of the present application, the "axial direction" is the axial direction of the valve core 100, that is, the extension direction of the center axis L of the valve core 100, the "circumferential direction" is the circumferential direction of the valve core 100, that is, the direction around the center axis L of the valve core 100, and the "radial direction" is the radial direction of the valve core 100, that is, the direction in the radial plane through the center axis L of the valve core 100. The "axial direction", "circumferential direction" and "radial direction" are perpendicular to each other.
[0064] In combination Figure 8 Figure 9 In some embodiments of the present application, a portion of the first conductive flow channel 111 is located radially inward of a portion of the second conductive flow channel 112, and the portion of the first conductive flow channel 111 is radially opposite to the portion of the second conductive flow channel 112.
[0065] For example, the first conducting flow channel 111 includes a first inlet 11, a first outlet 12, and a first flow channel section 13 communicated between the first inlet 11 and the first outlet 12, and the second conducting flow channel 112 has a second inlet 21, a second outlet 22, and a second flow channel section 23 communicated between the second inlet 21 and the second outlet 22, and the first inlet 11, the first outlet 12, the second inlet 21, and the second outlet 22 are all formed on the outer peripheral wall of the valve core 100.
[0066] The first inlet 11 and the first outlet 12 are axially spaced apart, the first flow channel section 13 is formed in the valve core 100 and communicates the first inlet 11 and the first outlet 12, and the first inlet 11 and the first outlet 12 are adapted to correspond to two valve ports 2111 in the same valve port row 211 which are spaced apart by other valve ports 2111, and fluid can flow into the first flow channel section 13 through the first inlet 11 and flow out of the first flow channel section 13 through the first outlet 12.
[0067] The second flow channel section 23 is located on the side of the first flow channel section 13 away from the center axis L of the valve core 100 in the radial direction of the valve core 100, i.e. the second flow channel section 23 is located on the radial outer side of the first flow channel section 13, and the second flow channel section 23 communicates the second inlet 21 and the second outlet 22, and the second inlet 21 and the second outlet 22 are adapted to communicate with two adjacent valve ports 2111 in the same valve port row 211, and fluid can flow into the second flow channel section 23 through the second inlet 21 and flow out of the second flow channel section 23 through the second outlet 22.
[0068] In the radial direction of the valve core 100, the first flow channel section 13 is located on the radial inner side of the second flow channel section 23 and is arranged opposite to the second flow channel section 23 in the radial direction, so that the inner and outer double-layer flow channels are formed on the valve core 100, the space in the valve core 100 is reasonably distributed while the flow path of the fluid is increased, the space utilization of the valve core 100 is improved, which is conducive to reducing the circumferential occupied space of the conducting structure 110 and reducing the complexity of the structural design of the valve core 100, and at the same time, the miniaturization design of the valve core 100 can be realized, thereby facilitating the reduction of the volume of the multi-way valve 200.
[0069] It can be understood that the inner and outer three-layer or more than three-layer flow channels can also be formed on the valve core 100 along the radial direction thereof, for example, the conducting structure 110 further includes a sixth conducting flow channel having a third flow channel section located on the radial inner side of the first flow channel section 13 and opposite to the first flow channel section 13 in the radial direction, and at this time, the first flow channel section 13, the second flow channel section 23, and the third flow channel section can form the inner and outer three-layer flow channels on the valve core 100.
[0070] In combination with Figure 8 and Figure 9In some embodiments of the present application, the distance between the mutually opposite wall surfaces of the first flow passage 111 and the second flow passage 112 is greater than or equal to 1.5 mm.
[0071] Specifically, the distance between the side wall surface of the first flow passage 111 close to the second flow passage 112 and the side wall surface of the second flow passage 112 close to the first flow passage 111 is greater than or equal to 1.5 mm, so as to improve the structural strength of the flow structure 110, prevent the flow structure 110 from being damaged due to excessive pressure when the fluid flows into the flow structure 110, and also increase the thermal resistance between the first flow passage 111 and the second flow passage 112, which is conducive to reducing the heat exchange amount caused by the temperature difference of the fluids flowing into the first flow passage 111 and the second flow passage 112 at the same time.
[0072] Referring to Figure 8 In some embodiments of the present application, the first recess 120 is formed on the valve core 100, the first recess 120 is open towards the radial outer side of the valve core 100, the first partition 121 is arranged in the first recess 120, the first partition 121 divides the first recess 120 into the first flow passage 111 and the second flow passage 112, and the first flow passage section 13 and the second flow passage section 23 are respectively arranged on the two sides of the first partition 121 in the radial direction of the valve core 100.
[0073] Specifically, the first recess 120 is formed on the outer peripheral wall of the valve core 100, and the first recess 120 is recessed in the direction close to the center axis L of the valve core 100 along the radial direction of the valve core 100, the first partition 121 is arranged in the first recess 120 and divides the first recess 120, so that the first recess 120 forms the first flow passage 111 and the second flow passage 112 arranged at intervals, and the first flow passage section 13 and the second flow passage section 23 are arranged at intervals on the two sides of the first partition 121 in the radial direction, so that the first flow passage section 13 and the second flow passage section 23 form a double-layer flow passage on the valve core 100. By arranging the first partition 121, it is conducive to simplifying the molding of the first flow passage 111 and the second flow passage 112, and improving the processing convenience of the valve core 100.
[0074] In combination Figure 8 And Figure 9 In some embodiments of the present application, the thickness t of the first partition 121 satisfies the following relationship: t≥1.5 mm.
[0075] It should be noted that the "thickness of the first partition 121" can be understood as the distance between the first flow passage 111 and the second flow passage 112.
[0076] By setting the thickness t of the first partition 121 to be greater than or equal to 1.5 mm to improve the structural strength of the first partition 121, it is beneficial to prevent the first partition 121 from being damaged due to excessive pressure when the fluid flows into the conducting structure 110, thereby preventing the conducting structure 110 from being damaged, while the heat insulation effect of the first partition 121 can be improved, which is beneficial to reduce the heat exchange amount of the fluid flowing into the first conducting flow channel 111 and the second conducting flow channel 112 due to temperature differences.

[0079] Further, relative to the second flow channel 23, the first flow channel section 13 is relatively close to the center axis L of the valve core 100, and the length of the first flow channel section 13 in the axial direction is greater than or equal to the length of the second flow channel section 23 in the axial direction, so as to facilitate the first flow channel section 13 to communicate with the first inlet 11 and the first outlet 12 located on both sides of the first partition 121 in the axial direction respectively.

[0102] Optionally, referring to Figure 5When the fourth guiding flow channel 140 has a small axial dimension, multiple fourth guiding flow channels 140 can be simultaneously arranged at intervals along the circumference and axial direction of the valve core 100. For example, four fourth guiding flow channels 140 can be provided. The four fourth guiding flow channels 140 can be arranged in a rectangular pattern on the outer peripheral wall of the valve core 100 and form one group of flow channels. When the valve core 100 is driven to rotate to the point where the group of flow channels is opposite to the multiple rows of valve ports 211, each fourth guiding flow channel 140 can connect the two corresponding valve ports 2111 in each row of valve ports 211 to realize a connection mode of the multi-way valve 200.

[0131] It should be noted that the "second communication state" refers to a state in which the multi-way valve 200 is applied to mode switching of the thermal management system 300 to communicate differentExemplarily, the flow channel group has a plurality of flow channel inlets and a plurality of flow channel outlets, in the second communication state, each flow channel inlet is opposite to a corresponding valve port 2111 in the radial direction, each flow channel outlet is opposite to a corresponding valve port 2111, and at least one valve port 2111 in the plurality of valve port columns 211 is closed by the valve core 100; in the first communication state, compared with the second communication state, each flow channel inlet is misaligned in the circumferential direction with respect to a corresponding valve port 2111 (the valve port 2111 corresponding to the same flow channel inlet is the same in the first communication state and the second communication state), but each flow channel inlet is still in communication with a corresponding valve port 2111, each flow channel outlet is misaligned in the circumferential direction with respect to a corresponding valve port 2111 (the valve port 2111 corresponding to the same flow channel outlet is the same in the first communication state and the second communication state), but each flow channel outlet is still in communication with a corresponding valve port 2111, so that all valve ports 2111 are in communication with the flow channels in the flow channel group.
[0132] It should be noted that the plurality of flow channel inlets includes the inlets of the plurality of flow channels, and the plurality of flow channel outlets includes the outlets of the plurality of flow channels. The inlets of the first flow channel 111 to the fifth flow channel 150 are respectively the flow channel inlets, and the outlets of the first flow channel 111 to the fifth flow channel 150 are respectively the flow channel outlets. For example, when the flow channel group is the first flow channel group 101, the plurality of flow channel inlets includes a plurality of inlets of the third flow channel 130 arranged in the axial direction, and the plurality of flow channel outlets includes a plurality of outlets of the third flow channel 130 arranged in the axial direction, which will not be described one by one.
[0133] Therefore, by arranging at least one flow channel group, the multi-way valve 200 can be switched between the first communication state and the second communication state, which is beneficial to reduce the number of flow channel groups, reduce the structural complexity of the valve core 100, reduce the machining difficulty of the valve core 100, and improve the production and machining efficiency of the valve core 100.
[0134] It can be understood that the flow channel group capable of switching the multi-way valve 200 between the first communication state and the second communication state can be arranged in multiple groups. When it is necessary to switch the multi-way valve 200 between the first communication state and the second communication state, the valve core 100 can be rotated to adjust the relative position between the valve port column 211 and the flow channel group adjacent thereto in the circumferential direction, so as to switch the multi-way valve 200 between the first communication state and the second communication state, and reduce the control difficulty of the multi-way valve 200.
[0135] As Figure 2As shown, in some embodiments of the present application, the number of valve ports 2111 in each column of valve port columns 211 is greater than or equal to 4, so as to increase the number of valve ports 2111 in the limited space of the multi-way valve 200, thereby increasing the number of external pipelines that can be communicated by the multi-way valve 200, and by cooperating with the valve ports 2111 and the flow channel groups, facilitating the realization of multiple communication states of the multi-way valve 200 and improving the functionality of the multi-way valve 200.

[0137] For example, the third flow-through channel 130 extends in the circumferential direction of the valve core 100, and the third flow-through channel 130 has an inlet and an outlet arranged adjacent to each other on both sides of the third flow-through channel 130 in the circumferential direction, and the third flow-through channel 130 can communicate two opposite valve ports 2111 in two adjacent valve port columns 211; the fourth flow-through channel 140 extends in the axial direction of the valve core 100, and the fourth flow-through channel 140 has an inlet and an outlet arranged adjacent to each other on both sides of the fourth flow-through channel 140 in the axial direction of the valve core 100, and the fourth flow-through channel 140 can communicate two adjacent valve ports 2111 in the same valve port column 211; the fifth flow-through channel 150 extends in the axial direction of the valve core 100, and the fifth flow-through channel 150 has an inlet and an outlet arranged spaced apart at both ends of the fifth flow-through channel 150 in the axial direction, and the fifth flow-through channel 150 can communicate two valve ports 2111 arranged spaced apart in the same valve port column 211.

[0141] The fourth through-flow channel 140 and the second through-flow channel 112 are both formed on the outer peripheral wall of the valve core 100 and extend in the axial direction, so as to further improve the machining convenience of the valve core 100, guarantee the regular structure of the valve core 100, and reduce the complexity of the structure of the valve core 100.
[0142] It should be noted that "the same structure" means the same shape, but the size can be the same or different, and the size design between the first through-flow channel 111 and the fifth through-flow channel 150 and the size between the fourth through-flow channel 140 and the second through-flow channel 112 can be determined according to actual production requirements, which is not limited here.
