Description

Technical Field

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

[0002] The conventional design method of a multi-way valve is to place all the flow ports to be connected adjacent to each other, forming a single-layer flow path spool structure. For a multi-way valve with this structure, it is impossible to connect non-adjacent (misaligned) flow ports.

[0003] Currently, in order to connect misaligned flow ports, generally there are two methods. One is to connect multiple multi-way valves in series, which will increase the system integration difficulty and control difficulty, and also increase the cost; the other is to set multiple multi-layer flow path spools in a multi-way valve. Each spool rotates independently to form multiple multi-layer flow path spool structures, and the misaligned flow path connection is realized inside the valve housing of the multi-way valve. Although setting multiple multi-layer flow path spool structures realizes the misaligned flow path connection, it increases the number of driving mechanisms, the number of parts and the product cost, and also increases the control difficulty.

[0004] Therefore, there is an urgent need to propose a multi-way valve and a thermal management system to solve the above technical problems. Summary of the Utility Model

[0041] This embodiment provides a multi-way valve, which can realize the connection of misaligned valve ports through a multi-layer valve core, with low control difficulty, high integration, simple structure, and low cost.

[0042] Specifically, as Figures 1-7 shown, the multi-way valve includes a valve body 100 and a valve core 200. Among them, an installation cavity 111 is provided in the valve body 100, and a plurality of valve ports 112 communicating with the installation cavity 111 are provided on the peripheral wall of the valve body 100. The valve core 200 is rotatably arranged in the installation cavity 111, and two end faces of the valve core 200 opposite to each other in the axial direction thereof respectively enclose a first confluence cavity 201 and a second confluence cavity 202 with the valve body 100.

[0043] The valve core 200 includes an inner flow channel 210 and an outer flow channel 220 in the radial direction thereof. There are a plurality of inner flow channels 210, and the plurality of inner flow channels 210 are arranged along the circumferential direction of the valve core 200. Each inner flow channel 210 extends along the axial direction of the valve core 200 and communicates with the first confluence cavity 201 and the second confluence cavity 202. The outer flow channel 220 includes a plurality of annular multi-layer flow-through areas 221 arranged in sequence along the axial direction of the valve core 200. Each layer of flow-through area 221 includes a plurality of sub-flow-through areas 2211 arranged along the circumferential direction of the valve core 200. By rotating the valve core 200, any sub-flow-through area 2211 can be made to correspond to the valve port 112 on the valve body 100.

[0044] At least two misaligned sub-flow-through areas 2211 are connected through the inner flow channel 210 and the first confluence cavity 201, or through the inner flow channel 210 and the second confluence cavity 202, so that the misaligned valve ports 112 corresponding to the two misaligned sub-flow-through areas 2211 are connected. Among them, the two misaligned sub-flow-through areas 2211 refer to the sub-flow-through areas 2211 located in non-adjacent layers of the flow-through areas 221, and the straight lines of the two sub-flow-through areas 2211 are not parallel to the axis of the valve core 200.

[0045] The multi-way valve provided in this embodiment achieves the purpose of connecting misaligned valve ports 112 through a multi-layer valve core 200. Compared with the existing method of connecting misaligned valve ports 112 by connecting multiple multi-way valves in series or using multiple valve cores 200, it has high integration, low control difficulty, simple structure, and low cost.

[0046] Further, at least two adjacent sub - flow - through areas 2211 are connected via the outer - layer flow channel 220, so that the adjacent valve ports 112 corresponding to the two adjacent sub - flow - through areas 2211 are connected.

[0047] Further, at least two non - adjacent sub - flow - through areas 2211 are connected via the inner - layer flow channel 210, so that the non - adjacent valve ports 112 corresponding to the two non - adjacent sub - flow - through areas 2211 are connected.

[0048] Among them, the two non - adjacent sub - flow - through areas 2211 connected via the inner - layer flow channel 210 refer to the sub - flow - through areas 2211 located in non - adjacent two - layer flow - through areas 221 respectively, and the straight line where the two sub - flow - through areas 2211 are located is parallel to the axis of the valve core 200.

[0049] See Figure 2 , in this embodiment, the multi - way valve is a ten - way valve, and the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 respectively correspond to the ten valve ports 112 of the ten - way valve.

[0050] Exemplarily, the valve ports 112 corresponding to two adjacent sub - flow - through areas 2211 can be valve port 112(7) and valve port 112(8), valve port 112(7) and valve port 112(6), valve port 112(9) and valve port 112(5), etc.

[0051] Exemplarily, the valve ports 112 corresponding to two non - adjacent sub - flow - through areas 2211 can be valve port 112(7) and valve port 112(4), valve port 112(7) and valve port 112(1), valve port 112(6) and valve port 112(3), etc.

[0052] Figure 6 For a working mode of the ten - way valve, in this working mode, the sub - flow - through areas 2211 corresponding to each valve port 112 are as Figure 3 shown.

[0053] In this working mode, valve port 112(6) is connected to valve port 112(7), valve port 112(5) is connected to valve port 112(9), and valve port 112(1) is connected to valve port 112(2). These three pairs of valve ports 112 are all connections between adjacent sub - flow - through areas 2211 and are realized through the outer - layer flow channel 220.

[0054] And, the misaligned valve ports 112(4) and valve ports 112(3) are also connected, which is realized through the inner - layer flow channel 210 and the second confluence cavity 202. Specifically, the sub - flow - through area 2211 corresponding to valve port 112(4) is connected to an inner - layer flow channel 210, the sub - flow - through area 2211 corresponding to valve port 112(3) is connected to another inner - layer flow channel 210, and these two inner - layer flow channels 210 are both connected to the second confluence cavity 202, asFigure 6 As shown by the arrow in Figure 6 , the coolant flows into the inner flow channel 210 from the valve port 112(4) and the sub-flow region 2211 corresponding to the valve port 112(4), then converges in the inner flow channel 210 and flows into the second confluence chamber 202. The coolant in the second confluence chamber 202 will enter each inner flow channel 210 communicating with it, and flow out of the valve port 112(3) through the sub-flow region 2211 corresponding to the valve port 112(3), thus realizing the connection of the offset valve ports 112.

[0055] It should be noted that although the coolant in the second confluence chamber 202 will enter each inner flow channel 210 communicating with it, it can only flow out of the valve body 100 when the inner flow channel 210 communicates with a certain sub-flow region 2211 and the sub-flow region 2211 corresponds to the valve port 112.

[0056] Figure 7 For another working mode of this ten-way valve, in this working mode, the sub-flow regions 2211 corresponding to each valve port 112 are as Figure 4 shown.

[0057] In this working mode, the valve port 112(4) is connected to the valve port 112(8), the valve port 112(5) is connected to the valve port 112(2), and the valve port 112(10) is connected to the valve port 112(3). These three pairs of valve ports 112 are all connected between adjacent sub-flow regions 2211, which is realized through the outer flow channel 220.

[0058] Moreover, the offset valve ports 112(6) and 112(1) are also connected, which is realized through the inner flow channel 210 and the first confluence chamber 201. Specifically, the sub-flow region 2211 corresponding to the valve port 112(6) is connected to an inner flow channel 210, the sub-flow region 2211 corresponding to the valve port 112(1) is connected to another inner flow channel 210, and both of these two inner flow channels 210 are connected to the first confluence chamber 201. As Figure 7 shown by the arrow in Figure 7 , the coolant flows into the inner flow channel 210 from the valve port 112(6) and the sub-flow region 2211 corresponding to the valve port 112(6), then converges in the inner flow channel 210 and flows into the first confluence chamber 201. The coolant in the first confluence chamber 201 will enter each inner flow channel 210 communicating with it, and flow out of the valve port 112(1) through the sub-flow region 2211 corresponding to the valve port 112(1), thus realizing the connection of the offset valve ports 112.

[0059] It should be noted that although the coolant in the first confluence chamber 201 will enter each inner flow channel 210 communicating with it, it can only flow out of the valve body 100 when the inner flow channel 210 communicates with a certain sub-flow region 2211 and the sub-flow region 2211 corresponds to the valve port 112.

[0060] Optionally, continue to see Figure 6 and Figure 7 A baffle 211 may be provided in the inner flow channel 210, and the baffle 211 divides the inner flow channel 210 into a first inner flow channel connected to the first confluence cavity 201 and a second inner flow channel connected to the second confluence cavity 202. Such a configuration can shorten the flow distance between the coolant and the first confluence cavity 201 or the second confluence cavity 202, thereby improving the flow efficiency.

[0061] Optionally, continue to see Figure 3 and Figure 4 , a plurality of sub-circulation areas 2211 in each circulation area 221 are formed by arranging a partition 222 in the circulation area 221. It can be understood that if the partition 222 between two adjacent sub-circulation areas 2211 in the same circulation area 221 is removed, the communication between two laterally adjacent sub-circulation areas 2211 can be achieved, that is, the communication between two laterally adjacent valve ports 112 can be achieved; if the partition 222 between two adjacent sub-circulation areas 2211 is removed between two adjacent circulation areas 221, the communication between two longitudinally adjacent sub-circulation areas 2211 can be achieved, that is, the communication between two longitudinally adjacent valve ports 112 can be achieved.

[0062] It is worth noting that the setting position of the partition 222 can be designed and adapted according to the communication requirements between the various valve ports 112 of the multi-way valve.

[0063] Optionally, continue to see Figure 4 The sub-flow area 2211 in the flow area 221 adjacent to the second confluence cavity 202 can also be connected to the second confluence cavity 202. Such an arrangement is conducive to reducing flow resistance.

[0064] Optionally, continue to see Figure 1 In this embodiment, the valve body 100 includes a valve housing 110 and a valve cover 120. The installation cavity 111 is arranged in the valve housing 110 and has an opening at one end. The valve cover 120 is sealed and blocked at the opening of the installation cavity 111. When installing the valve core 200, the valve cover 120 is opened, and the valve core 200 is installed in the installation cavity 111 through the opening of the installation cavity 111. Then, the valve cover 120 is installed to block the opening of the installation cavity 111. Such a configuration facilitates the installation and removal of the valve core 200.

[0065] Further, see Figure 6 and Figure 7 Among the two end faces of the valve core 200 that are opposite to each other along its axial direction, one end face, together with the bottom wall of the installation cavity 111 and the inner peripheral wall of the installation cavity 111, forms a first confluence cavity 201, and the other end face, together with the valve cover 120 and the inner peripheral wall of the installation cavity 111, forms a second confluence cavity 202.

[0066] Further, continue to refer to Figure 1 , in this embodiment, a sealing ring 300 is sleeved on one end of the valve core 200 close to the valve cover 120, and the sealing ring 300 is located between the valve core 200 and the inner wall of the installation cavity 111. By providing the sealing ring 300, the mutual independence between the second confluence cavity 202 and the first confluence cavity 201 can be ensured.

[0067] Optionally, continue to refer to Figure 3 , an installation groove 230 can be annularly provided at one end of the valve core 200 close to the valve cover 120, and the installation groove 230 is used for installing the sealing ring 300. By fixing the sealing ring 300 through the installation groove 230, the stability of the installation of the sealing ring 300 is improved, and further the reliability of the mutual independence between the first confluence cavity 201 and the second confluence cavity 202 is improved.

[0068] Optionally, continue to refer to Figure 1 , the multi-way valve further includes an inner gasket 500, and the inner gasket 500 is arranged between the outer side of the outer flow channel 220 of the valve core 200 and the inner wall of the installation cavity 111 for sealing the gap between the valve core 200 and the inner wall of the installation cavity 111.

[0069] Optionally, continue to refer to Figure 1 , the multi-way valve further includes an outer gasket 600, and the outer gasket 600 is arranged at the valve port 112. The outer gasket 600 is used for sealing between the valve port 112 and the flow channel plate used in cooperation with the multi-way valve.

[0070] Optionally, in this embodiment, the valve core 200 is of an integral structure. The valve core 200 can be directly processed and produced by a mold, which is beneficial to improving production efficiency.

[0071] Further, continue to refer to Figures 1-3 , a rotating shaft 240 is provided at one end of the valve core 200, the rotating shaft 240 is sealingly penetrated through the valve body 100, an actuator 400 is provided outside the valve body 100, the actuator 400 is connected to the rotating shaft 240, and the actuator 400 rotates the valve core 200 in the installation cavity 111 by driving the rotating shaft 240. That is, through the cooperation of the actuator 400 and the rotating shaft 240, the automatic control of the connection between different valve ports 112 of the multi-way valve can be realized.

[0072] Further, continue to refer to Figure 2 , in this embodiment, the plurality of valve ports 112 are located in the same plane. With such a setting, it is convenient for the plurality of valve ports 112 to be directly butted and communicated with the flow channels on the flow channel plate, which is beneficial to simplifying the pipeline layout and improving the integration degree of the system.

[0073] This embodiment also provides a thermal management system, including at least one of the above multi-way valves.
