Description

Technical Field

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

[0002] Multi-way valves are widely used in the field of fluid connectivity. For example, in the thermal management system of pure electric vehicles, multiple circulation loops are usually designed based on the thermal management requirements of the vehicle itself. Multiple circulation loops need to be switched through valves to achieve thermal management requirements of various working conditions. If multiple electronic water valves are used to switch the circulation loops, there are disadvantages such as high cost and large space occupation. Therefore, multiple electronic water valves are often integrated into a multi-way valve. With the development of technology, multi-way valves have developed from common three-way and four-way valves to those that can achieve the connection of ten or even more waterways.

[0003] One solution of a multi-way valve in the prior art is that a plurality of valve ports are provided on the valve body, and a plurality of flow channel grooves are provided on the valve core. By rotating the valve core so that one flow channel groove is connected to a plurality of valve ports, the water flow connection mode can be switched. However, in this prior art, the flow channel groove can usually only connect adjacent valve ports, which limits the diversity of water flow connection modes and is difficult to meet the application requirements of more complex connection modes.

[0004] In view of this, it is necessary to propose a new technical solution to overcome the shortcomings of the prior art. Utility Model Content

[0005] Based on this, the present application provides a multi-way valve, which is convenient for realizing more diverse water flow patterns and can simplify the structural design of the docking parts that cooperate with the multi-way valve.

[0006] To this end, the present application adopts the following technical solution: a multi-way valve, comprising a valve body and a valve core movably arranged in the valve body, the valve body being provided with a plurality of valve ports, the valve core being provided with a plurality of flow channel grooves, at least one flow channel groove being capable of connecting two or more adjacent valve ports among the plurality of valve ports, wherein the valve body is provided with at least one connecting flow channel, and the connecting flow channel connects at least two non-adjacent valve ports.

[0007] In one embodiment, the plurality of valve ports are arranged in an array, wherein adjacent valve ports are adjacent in the same row of the array or in the same column of the array.

[0008] In one embodiment, the two non-adjacent valve ports include the two valve ports being in the same row or column separated by at least one valve port, and / or the two valve ports being in different rows and columns.

[0009] In one embodiment, the valve body is a hollow cylinder with an annular wall, and a plurality of valve ports penetrate through the annular wall of the valve body, and the communication flow channels are formed inside the annular wall.

[0010] In one embodiment, a plurality of valve ports connected by the communication flow channels are marked with the same label.

[0011] In one embodiment, the flow channel groove includes a plurality of transverse grooves and a plurality of longitudinal grooves. The transverse grooves are used to connect a plurality of laterally adjacent valve ports, and the longitudinal grooves are used to connect a plurality of longitudinally adjacent valve ports.

[0012] In one embodiment, the multi-way valve includes an actuator for driving the valve core to move relative to the valve body.

[0013] In one embodiment, the multi-way valve includes an internal leakage seal and an external leakage seal. The internal leakage seal forms a seal between a plurality of flow channel grooves of the valve core, and the external leakage seal forms a seal between the plurality of valve ports.

[0014] The present application also adopts the following technical solution: a vehicle thermal management system includes the multi-way valve as described in any one of the above embodiments.

[0015] The present application also adopts the following technical solution: a vehicle includes the vehicle thermal management system as described above.

[0016] The multi-way valve provided by the present application is provided with at least one communication flow channel in the valve body. The communication flow channel connects at least two non-adjacent valve ports, so that the connection mode of the valve ports is more diverse, which is convenient for realizing more diverse water flow patterns to meet diverse water flow connection requirements, and the structural design of the docking parts cooperating with the multi-way valve can be simplified.

[0029] Unless otherwise defined, all technical and scientific terms used in the description of this application have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used in the description of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the description of this application includes any and all combinations of one or more of the related listed items.

[0030] Please refer to Figures 1 to 5 As shown, this application provides a multi-way valve, which includes a valve body 2 and a valve core 3 movably arranged in the valve body 2. A plurality of valve ports 20 are provided on the valve body 2, and a plurality of flow channel grooves 30 are provided on the valve core 3. At least one flow channel groove 30 can connect two or more adjacent valve ports 20 among the plurality of valve ports 20. Among them, at least one communication flow channel 23 is provided in the valve body 2, and the communication flow channel 23 connects at least two non-adjacent valve ports 20.

[0031] For the multi-way valve provided by this application, the communication flow channel 23 provided in the valve body 2 connects at least two non-adjacent valve ports 20, making the connection mode of the valve ports 20 more diverse, facilitating the realization of more diverse water flow patterns to meet diverse water flow connection requirements, and moreover, the structural design of the docking parts cooperating with the multi-way valve can be simplified.

[0032] Please refer to Figure 1 and Figure 2As shown, in this embodiment, the multi-way valve includes a valve body 2 and a valve core 3, an actuator 1 for driving the valve core 3 to move relative to the valve body 2, and an end cap 5 for fixing to the valve body 2. The valve core 3 is generally cylindrical and is assembled in the valve body 2. A plurality of flow channel grooves 30 are provided on the valve core 3. The flow channel grooves 30 include a plurality of transverse grooves 31 and a plurality of longitudinal grooves 32. The transverse grooves 31 extend horizontally and are used to connect a plurality of laterally adjacent valve ports 20 on the valve body 2; the longitudinal grooves 32 extend longitudinally and are used to connect a plurality of longitudinally adjacent valve ports 20 on the valve body 2. Among them, the horizontal direction is the direction parallel to the axial direction of the valve core 3, and the longitudinal direction is the direction perpendicular to the axial direction of the valve core 3. The transverse grooves 31 and the longitudinal grooves 32 are both multiple. By rotating the valve core 3, different transverse grooves 31 on the valve core 3 can be connected to different laterally arranged valve ports 20, and different longitudinal grooves 32 can be connected to different longitudinally arranged valve ports 20, so as to achieve different water flow connection modes.

[0033] Please refer to Figure 3 and Figure 4 As shown, for convenience of description, Figure 4 the different valve ports 20 are schematically numbered in the figure. The solutions in the prior art usually can only achieve the connection between adjacent valve ports 20. For example, when two valve ports 20 numbered 1 and 2 are located in the same transverse groove 31 on the valve core 3, the two valve ports 20 numbered 1 and 2 are connected; similarly, for example, when two valve ports 20 numbered 1 and 6 are located in the same longitudinal groove 32 on the valve core 3, the two valve ports 20 numbered 1 and 6 are connected. Of course, according to the different lengths of the flow channel grooves 30, the simultaneous connection of three or more adjacent valve ports 20 can also be achieved. For example, the valve ports 20 numbered 1, 2, and 3 can be simultaneously connected. However, as the connection mode becomes more and more complex, there is often a need to simultaneously connect non-adjacent valve ports 20. For example, in a working condition, it is required that the valve port 20 numbered 6 be simultaneously connected to the valve ports 20 numbered 1, 7, and 9; it can be understood that the valve port 20 numbered 6 and the valve port 20 numbered 1 can be connected through the longitudinal groove 32, and the valve port 20 numbered 6 and the valve port 20 numbered 7 can be connected through the transverse groove 31. In the existing solution, the valve port 20 numbered 6 and the valve port 20 numbered 9 cannot be connected, and complex structures need to be set on the docking part to achieve this.

[0034] Please refer to Figure 5As shown, the valve ports numbered 1 to 9 are respectively the first valve port, the second valve port, the third valve port, the fourth valve port, the fifth valve port, the sixth valve port, the seventh valve port, the eighth valve port, and the ninth valve port. The valve port 20 after the valve port 20 numbered 9 is the tenth valve port. The present application connects the non-adjacent valve ports 20 by providing a connecting flow channel 23 in the valve body 2. For example, the tenth valve port after the valve port 20 numbered 9 is connected to the sixth valve port numbered 6 through the connecting flow channel 23. At the same time, in order to facilitate identification of the connection between the valve ports 20, the multiple valve ports 20 connected by the connecting flow channel 23 are marked with the same mark. For example, the valve port 20 after the valve port 20 numbered 9 is marked as No. 6, that is, the tenth valve port 21 is marked as No. 6. As Figure 5 As shown, the sixth valve port 22 and the tenth valve port 21 are connected through a connecting channel 23, and the sixth valve port 22 and the tenth valve port 21 have the same or matching identification.

[0035] In this embodiment, the valve body 2 is a hollow cylindrical shape having an annular wall, the plurality of valve ports 20 penetrate the annular wall of the valve body 2, and the connecting flow channel 23 is formed inside the annular wall. The plurality of valve ports 20 are arranged in an array, wherein adjacent valve ports 20 include being adjacent in the same row of the array or in the same column of the array. For example, the valve ports 20 labeled 1 and 2, 2 and 3, etc. are adjacent in the same row, and the valve ports 20 labeled 1 and 6, 2 and 7, etc. are adjacent in the same column. The two non-adjacent valve ports 20 include the two valve ports 20 being separated by at least one valve port 20 in the same row or in the same column, such as the valve ports 20 labeled 1 and 3 or 4 or 5, the valve ports 2 and 4 or 5, etc. Alternatively, the two non-adjacent valve ports 20 include the two valve ports being located in different rows and columns, such as the valve ports 20 labeled 1 and any of the valve ports 20 labeled 7 to 9, 6, 8, 9, etc. It should be noted that the drawings of this embodiment are illustrated by taking the valve ports 20 in two rows and five columns as an example. In other embodiments, the valve ports may also be in other arrays, and are not limited to rectangular arrays, and may also be arranged as annular arrays, etc. In the above embodiment, an example is given in which a connecting flow channel 23 is arranged in the valve body 2 to connect two valve ports 20. It is understandable that in other embodiments, multiple connecting flow channels 23 may also be arranged in the valve body 2 to connect more groups of valve ports 20.

[0036] When in use, the valve core 3 is connected to the valve body 2, and the valve core 3 is connected to the actuator 1, the valve port 20 on the valve body 2 is connected to the corresponding docking piece, and the actuator 1 is, for example, an electric device, which is controlled by an electrical signal to drive the valve core 3 to move, so as to connect different valve ports 20 and realize the switching of water flow modes.

[0037] The present application also provides a vehicle thermal management system, including the multi-way valve described in any of the above embodiments. By switching different connection modes through the multi-way valve, the vehicle thermal management system can be adapted to different operating conditions. The present application also provides a vehicle, which includes the vehicle thermal management system described above.

[0038] From the description of the specific embodiments above, it can be seen that for the multi-way valve provided by the present application, at least one communication flow channel 23 is provided in the valve body 2, and the communication flow channel 23 connects at least two non-adjacent valve ports 20, making the connection mode of the valve ports 20 more diverse. The non-adjacent valve ports 20 can also be connected through the flow channel groove 30 on the valve core 3, facilitating the realization of more diverse water flow patterns to meet diverse water flow connection requirements, and the structural design of the docking component cooperating with the multi-way valve can be simplified.

[0039] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.

[0040] The above-described embodiments only represent several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
