[0054] In the description of the present application, the description of the terms "one embodiment", "some embodiments", "exemplary embodiment", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in combination with the embodiment or example are included in at least one embodiment or example of the present application. In the present specification, the exemplary description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0055] With the continuous improvement of the energy efficiency of thermal management systems, in order to obtain higher system energy efficiency, the architecture of the thermal management system is also increasingly complex, and therefore the corresponding cooling circulation loop design is also increasingly complex. For example, in the field of new energy vehicles, in order to improve the cruising range of electric vehicles, it is necessary to realize battery heating by a coolant electric heater, heat dissipation of the battery and the drive system through a radiator, and heating of the battery by using waste heat of the drive system, etc.

[0056] In order to improve the integration of the coolant pipeline, the thermal management system often adopts a combination structure of a flow channel plate and a multi-way valve to realize the switching and distribution of multiple fluid paths. The flow channel plate is used to connect with each pipeline, and the multi-way valve is used to control the on-off of different flow channels. In the prior art, the multi-way valve and the flow channel plate are independent components, which are fixedly connected by bolts or buckles, etc. This way not only has a complex assembly process, but also has more sealing surfaces, which is easy to cause coolant leakage.

[0057] More specifically, in the prior art, the water port of the valve body on the multi-way valve and the valve core needs to be sealed by a sealing element, and the water port of the valve body and the flow channel plate also needs to be sealed by a sealing element, thereby at least two sealing structures are required.

[0058] In addition, in the related art, the valve core is arranged in the flow channel plate, thereby further improving the integration of the multi-way valve and the flow channel plate. However, the valve core in the prior art is often a three-way valve or a four-way valve, and the number of interfaces that can be arranged on the entire flow channel plate is limited due to the number of flow channels on the valve core, and the space utilization rate of the flow channel plate is not high.

[0059] To solve the above problems, the present application provides a multi-way valve, as shown in Figure 1 and Figure 2 The valve core 200 can be integrated inside the flow channel plate 100, so that only a sealing element 300 needs to be arranged between the valve core 200 and the flow channel plate 100 to achieve the sealing effect, thereby reducing the number of sealing surfaces and reducing the risk of leakage. The number of pipelines that can be integrated by the flow channel plate can be increased by the multi-layer structure design, thereby improving the integration of the multi-way valve.

[0060] Specifically, the multi-way valve includes a flow channel plate 100 and a valve core 200. It should be noted that in order to reduce the number of valve cores 200 and increase the number of flow channels of a single valve core 200, a multi-layer structure is arranged on the valve core 200, each layer of structure corresponds to a different fluid passage, and the connection or disconnection of different passages is realized by rotating or moving the valve core 200. Therefore, the flow channel plate 100 also has a corresponding multi-layer structure.

[0061] For example, referring to Figures 3 to 5As shown, the flow channel plate 100 comprises a first layer structure 110 and a second layer structure 120, which are distributed along the thickness direction of the flow channel plate 100. A plurality of first channels 111 are defined in the first layer structure 110, and a plurality of second channels 121 are defined in the second layer structure 120. It can be understood that the flow channel plate 100 can be connected to a plurality of external pipelines, such as battery coolant, condenser coolant, engine coolant, etc. By arranging multiple layers in the flow channel plate 100, the layout of the internal flow channels is enriched, and different coolant circuits can be integrated in the flow channel plate 100.

[0062] In addition, in order to further improve the integration of the flow channel plate 100, the flow channel plate 100 further defines an accommodation cavity 130 for accommodating the valve core 200. The accommodation cavity 130 penetrates the first layer structure 110 and the second layer structure 120, and each of the first channels 111 and the second channels 121 is in communication with the accommodation cavity 130. The first channels 111 form first channel openings 112 on the accommodation cavity 130, and the second channels 121 form second channel openings 122 on the accommodation cavity 130.

[0063] The valve core 200 is arranged in the accommodation cavity 130. Correspondingly, the valve core 200 is provided with a third layer structure 210 and a fourth layer structure 220, which are distributed along the axis of the valve core 200. The third layer structure 210 corresponds to the first layer structure 110, and the fourth layer structure 220 corresponds to the second layer structure 120. The valve core 200 defines a first flow channel 211 at least partially located in the third layer structure 210, and a second flow channel 221 at least partially located in the fourth layer structure 220.

[0064] The first flow channel 211 and the second flow channel 221 are arranged in space alternately. For example, Figures 6 to 8As shown, the valve core 200 includes two first flow channels 211 and two second flow channels 221, wherein the first flow channels 211 are composed of two intersecting straight flow channels, both of which are arranged in the third layer structure 210 and are not communicated with each other, and the two ends of the first flow channels 211 form two first water outlets 212 on the outer peripheral wall of the third layer structure 210. In other embodiments, the first flow channels 211 can also be in the form of curves, arcs, etc. Part of the second flow channels 221 is arranged in the third layer structure 210, and the other part is arranged in the fourth layer structure 220. Specifically, the second flow channels 221 include two first segments 223 and one second segment 224, the first segments 223 are located in the third layer structure 210, and the second segment 224 is located in the second layer structure 120, the two ends of the second segment 224 are respectively communicated with a first segment 223, the first segment 223 forms a second water outlet 213 on the outer peripheral wall of the third layer structure 210, and the second segment 224 forms a third water outlet 222 on the outer peripheral wall of the fourth layer structure 220.

[0065] At least two of each first channel 111 and second channel 121 can be communicated through the first flow channel 211 or the second flow channel 221. For example, two first channels 111 can be communicated through the first flow channel 211, or two second channels 121 can be communicated through the second flow channel 221, or a first channel 111 and a second channel 121 can be communicated through the first flow channel 211 or the second flow channel 221. When the valve core 200 is driven to rotate relative to the flow channel plate 100, the communication state of each first channel 111 and second channel 121 can be switched.

[0066] It should be explained that the communication state includes the communication relationship with each first flow channel 211 or each second flow channel 221, and also includes the on-off relationship with the first flow channel 211 or the second flow channel 221. For example, with respect to the first flow channel 211, the communication state includes the on-off relationship between the first flow channel 211 and each first channel 111, and the on-off relationship between the first flow channel 211 and each second channel 121. Figure 14 For example, with respect to the first flow channel 211, the communication state includes the on-off relationship between the first flow channel 211 and each first channel 111, and the on-off relationship between the first flow channel 211 and each second channel 121. Figure 15 For example, with respect to the first flow channel 211, the communication state includes the on-off relationship between the first flow channel 211 and each first channel 111, and the on-off relationship between the first flow channel 211 and each second channel 121.

[0067] Based on the above, the multi-way valve of the application reduces the sealing surface of the multi-way valve by integrating the valve core 200 in the interior of the flow channel plate 100, and reduces the probability of liquid leakage of the multi-way valve. Secondly, the multi-way valve and the valve core 200 are both multi-layer structures, and the number of flow channels that can be arranged is further improved, thereby greatly enriching the on-off mode of the multi-way valve.

[0068] Each first flow channel 211 defines two first water inlets 212 on the outer periphery of the valve core 200, and each second flow channel 221 defines two second water inlets 213 on the outer periphery of the valve core 200. Both the first water inlets 212 and the second water inlets 213 are located on the third layer structure 210 of the valve core 200 and are staggered in the circumferential direction of the valve core 200 to avoid mutual interference. The arrangement angle and position of the first water inlets 212 and the second water inlets 213 on the third layer structure 210 can be adjusted according to actual flow channel requirements to achieve different connection methods.

[0069] Alternatively, multiple water passages can be provided in a single flow channel to achieve a multi-pass effect. For example, at least one second flow channel 221 further defines a third water passage 222 on the outer periphery of the valve core 200. The third water passage 222 is located on the fourth layer structure 220, thereby enabling communication with the second channel 121 in the second layer structure 120. Figures 6 to 8 As shown, a second water inlet 213 is provided at one end of the second flow channel 221, and a second water inlet 213 and a third water inlet 222 are provided at the other end, so that the second flow channel 221 can connect the two first channels 111 and the second channel 121. In other embodiments, both ends of each second flow channel 221 may also be provided with a second water inlet 213 and a third water inlet 222.

[0070] In other embodiments, the multi-channel effect can also be achieved by connecting the first channel 111 and the second channel 121. For example, the first channel 211 can be connected to two first channels 111 respectively, and one of the first channels 111 can also be connected to other first channels 111 or second channels 121, thereby achieving the multi-channel effect of one channel for water inlet and multiple channels for water outlet, or one channel for water outlet and multiple channels for water inlet.

[0071] Furthermore, such as Figure 5 and Figure 8 As shown, the valve core 200 includes two third water inlets 222. The second layer structure 120 includes two second channels 121, which surround the receiving cavity 130. One second channel 121 is connected to the receiving cavity 130 through the two second channel inlets 122, while the other second channel 121 is not connected to the receiving cavity 130. It is understood that in other application scenarios, both second channels 121 can be configured to be connected to the receiving cavity 130 through the second channel inlets 122.

[0072] For example Figures 9 to 11 The illustrated embodiment will be used as an example. Regarding the second channel 121 communicating with the accommodating cavity 130, it has at least three operating states: a high flow rate state, a low flow rate state, and a closed state. In the high flow rate state, such as...Figure 9 As shown, the valve core 200 is rotated to a first angular position, at which time two second channel openings 122 are respectively communicated with one third water passage 222, that is, two second flow channels 221 are communicated with the second channel 121, thereby the flow in the second channel 121 is large, which can meet the high flow demand. In a small flow state, as shown in FIG. 6B, the valve core 200 is rotated to a second angular position, at which time only one second channel opening 122 is communicated with one third water passage 222, that is, one second flow channel 221 is communicated with the second channel 121, thereby the flow in the second channel 121 is small, which can meet the low flow demand. In a closed state, the valve core 200 is rotated to a third angular position, at which time both second channel openings 122 are not communicated with any water passage, thereby cutting off the water flow to completely close the second channel 121. Through the switching of the above three states, the water flow control demand in different use scenarios can be flexibly adapted, and the practicality and operation convenience of the valve core 200 are improved. Figure 10 As shown, the valve core 200 is rotated to a first angular position, at which time two second channel openings 122 are respectively communicated with one third water passage 222, that is, two second flow channels 221 are communicated with the second channel 121, thereby the flow in the second channel 121 is large, which can meet the high flow demand. In a small flow state, as shown in FIG. 6B, the valve core 200 is rotated to a second angular position, at which time only one second channel opening 122 is communicated with one third water passage 222, that is, one second flow channel 221 is communicated with the second channel 121, thereby the flow in the second channel 121 is small, which can meet the low flow demand. In a closed state, the valve core 200 is rotated to a third angular position, at which time both second channel openings 122 are not communicated with any water passage, thereby cutting off the water flow to completely close the second channel 121. Through the switching of the above three states, the water flow control demand in different use scenarios can be flexibly adapted, and the practicality and operation convenience of the valve core 200 are improved.

[0073] For a more specific application scenario, for example: in high-temperature working conditions, the large flow state can be adopted to increase the flow of cooling liquid and improve the heat dissipation capacity; while in low-temperature starting, the small flow state or the closed state can be adopted to reduce heat loss and speed up the temperature rising.

[0074] In addition, in the third layer structure 210 of the valve core 200, the first water passage 212 and the second water passage 213 adjacent thereto define a blocking part 214, wherein when one of the first channels 111 is communicated with the first water passage 212 or the second water passage 213, the other first channel 111 is closed by the blocking part 214. As shown in FIG. 6A, Figure 14 and Figure 16 As shown, the nine first channels 111 in the first layer structure 110 are respectively labeled by 1 to 9, Figure 14 the No. 7 channel is communicated with the first water passage 212, and the No. 9 channel is closed by the blocking part 214. Figure 16 the No. 9 channel is communicated with the first water passage 212, and the No. 7 channel is closed by the blocking part 214.

[0075] Therefore, in the application of the thermal management system, the two first channels 111 can be applied to the pipe design of selective communication, for example, if the A component has two cooling liquid inlets B and C, either the cooling liquid is introduced through the B inlet or the cooling liquid is introduced through the C inlet, then the B inlet can be communicated with the No. 7 channel, and the C inlet can be communicated with the No. 9 channel, thereby only one inlet between the B inlet and the C inlet is communicated with the valve core 200.

[0076] Further, based on the foregoing, as shown in FIG. 6A, Figure 14 and Figure 16As shown, some of the first passages 111 form small passage openings (for example, the 9th passage and the 7th passage form small passage openings) on the inner circumferential wall of the valve body, and the rest of the first passages 111 form large passage openings (for example, the rest of the first passages 111 form large passage openings except the 9th passage and the 7th passage) on the inner circumferential wall of the valve body, and the arc length of the large passage openings is greater than the arc length of the blocking portion 214, so as to avoid the situation that the large passage openings cannot be opened due to the fact that the valve core 200 is not moved to the position. In the embodiment of the present application, the 7th passage and the 9th passage are opened alternatively, and the rest of the first passages 111 are always in the open state although the different communication relationships can be changed with the rotation of the valve core 200.

[0077] In some embodiments, the multi-way valve comprises a controller which can obtain the reference position information and the rotation angle information, and obtain the real-time position information of the valve core 200 based on the reference position information and the rotation angle information. For example, the multi-way valve further comprises a sensor which can obtain the rotation angle information of the valve core 200. For example, the valve core 200 is rotated clockwise by 30° from the initial position, and the change value (i.e. the rotation angle information) is recorded as +30°. The controller determines that the valve core 200 is rotated to the position of 30° (the real-time position information) based on the reference position information of 0°, and changes the reference position information of the valve core 200 to +30° as the calculation reference for the next rotation. If the valve core 200 is further rotated counterclockwise by 10° on this basis, the change value is recorded as -10°. The controller determines that the valve core 200 is rotated to the position of 20° based on the reference position information of +30°. Thus, the position information acquisition and feedback of the valve core 200 are realized.

[0078] Alternatively, in other embodiments, the controller can accumulate the rotation angle information of each rotation, and calculate based on the fixed reference position information, so as to also obtain the real-time position information of the valve core 200.

[0079] It can be understood that due to the existence of certain error in the acquisition accuracy of the sensor, the cumulative error may be generated after the valve core 200 is rotated for many times. Therefore, the position of the valve core needs to be recalibrated in the case of vehicle maintenance, vehicle regular self-checking, etc., so as to ensure the accuracy of the position of the valve core 200. Thus, the multi-way valve further comprises a reset mode. In the reset mode, the valve core 200 is driven to rotate to a reset point. In the reset point, the rotation of the valve core 200 is limited, so as to reset the reference position information or the rotation angle information, etc. to the initial value by the controller.

[0080] More specifically, in order to realize the reset calibration, the calibration mechanism is arranged on the valve core 200 and the flow passage plate 100. The calibration mechanism comprises a first abutting protrusion 131 (as shown in FIG. 13) arranged on the cavity wall of the accommodating cavity 130, and a second abutting protrusion 230 (as shown in FIG. 23) arranged on the valve core 200. Figure 5 The first abutting protrusion 131 and the second abutting protrusion 230 are arranged to be abutted with each other when the valve core 200 is rotated to the reset point, so as to reset the reference position information or the rotation angle information, etc. to the initial value by the controller.Figure 8 As shown), Figure 12 As shown, a axial protrusion 132 is provided at the bottom of the accommodating cavity 130, and a hollow rotating shaft 240 is provided at the bottom of the valve core 200. The axial protrusion 132 is inserted into the rotating shaft 240, and the rotating shaft 240 provides abutment support between the valve core 200 and the bottom wall of the accommodating cavity 130. The rotating shaft 240 abuts against the bottom wall of the valve core 200 with a small contact area, which facilitates the rotation of the valve core 200. Furthermore, after the rotating shaft 240 abuts against the bottom wall of the valve core 200, a gap area is defined between the fourth layer structure 220 of the valve core 200 and the bottom wall of the accommodating cavity 130. The second abutment protrusion 230 is connected to the bottom of the fourth layer structure 220. When the valve core 200 is installed into the accommodating cavity 130, the first abutment protrusion 131 is inserted into the aforementioned gap area. The valve core 200 can rotate along the first rotation direction to the first abutment protrusion 131 and the second abutment protrusion 230, and set this abutment position as a reset point to calibrate the reference position information or rotation angle information. For example, when the actuator 450 detects that the rotation of the valve core 200 along the first rotation direction is obstructed (at which time the first abutment protrusion 131 and the second abutment protrusion 230 are abutting), it determines that the valve core 200 has moved to the reset point to calibrate the reference position information.

[0081] The reset point setting ensures that the valve core 200 can periodically return to a known reference position during long-term operation, thereby eliminating positioning deviations caused by the accumulation of sensor errors and ensuring the stable operation of the thermal management system under complex conditions. Furthermore, limiting the reset point through mechanical contact provides higher reliability and anti-interference capabilities compared to calibration methods relying solely on electronic signals or software algorithms.

[0082] In some embodiments, the first channel 111 is connected to the second channel 121, thereby enabling the transfer of liquid input to the first layer structure 110 to the second layer structure 120, or the transfer of liquid input to the second layer structure 120 to the first layer structure 110, so as to realize fluid interaction between different layer structures.

[0083] In some embodiments, the multi-way valve further includes a seal 300, such as Figure 2 and Figure 13 As shown, the seal 300 is located between the cavity wall of the receiving cavity 130 and the valve core 200, and is fixedly connected to the cavity wall of the receiving cavity 130. The seal 300 is made of soft material and can abut against both the valve core 200 and the cavity wall of the receiving cavity 130 to prevent water leakage. The seal 300 has through holes corresponding to each channel opening to facilitate communication between the channel opening and the water inlet. Additionally, as... Figure 13As shown, the cavity wall of the accommodating cavity 130 is provided with at least one set of rotation-stopping structures, which abut against the sealing member 300 to limit the relative rotation between the sealing member 300 and the cavity wall of the accommodating cavity 130.

[0084] More specifically, each rotation-stopping structure includes two oppositely arranged buckles 310, which define clamping grooves 311. The sealing member 300 is arranged around the valve core 200, and the two ends of the sealing member 300 are inserted into the two clamping grooves 311, respectively, to complete the fixation of the sealing member 300 and the cavity wall of the accommodating cavity 130.

[0085] The accommodating cavity 130 is formed with an opening on the surface of the flow channel plate 100, and the valve core 200 is inserted into the accommodating cavity 130 through the opening. In some embodiments, the multi-way valve further includes an end cover 400 and an actuator 450. The end cover 400 covers the opening to seal the accommodating cavity 130. It can be understood that the end cover 400 and the flow channel plate 100 can be fixed by a detachable connection structure such as a threaded connection or a clamping connection, or can be fixed by a non-detachable process such as welding. When the end cover 400 and the flow channel plate 100 are connected by welding, the sealing performance is better.

[0086] The actuator 450 is arranged outside the accommodating cavity 130, and the connecting shaft of the actuator 450 penetrates the end cover 400 and is connected with the valve core 200. As shown in Figure 2 As shown, the top of the valve core 200 is provided with a spline for interfacing with the connecting shaft, and the actuator 450 is used to drive the valve core 200 to rotate. It can be understood that the actuator 450 is in communication connection with a controller, and can adjust the rotation speed and rotation timing of the valve core 200 under the control of the controller.

The second layer structure 120 is provided with two second channels 121, one of which is in communication with the accommodating cavity 130 and is marked as No. 10 channel. The No. 7 channel and the No. 9 channel are adjacent, and the No. 7 channel and the No. 9 channel form a small channel opening on the cavity wall of the accommodating cavity 130, and the remaining channels form a large channel opening.
