[0024] In addition, it should be noted that in the description of the present utility model, it should be stated that the terms indicating directions such as "upper", "lower", "front", "rear", etc. in each embodiment are only used to simplify the description of the positional relationship based on the drawings in the specification, and do not represent that the indicated elements and devices, etc. must operate according to the specific directions and limited operations, methods, and structures in the specification.

[0025] A coordinate system XYZ is established herein.

[0026] As Figures 1-4 shown, a multi-way valve assembly according to an embodiment of the present utility model includes a valve body 1, and the valve body 1 includes at least two sub-valve bodies 11 and a first fixing seat 12. Each of the sub-valve bodies 11 is respectively connected to the first fixing seat 12, and each of the sub-valve bodies 11 has a plurality of connectors 111, and the connectors 111 of the same sub-valve body 11 communicate with each other.

[0027] Specifically, the valve body 1 may include two, three or more sub-valve bodies 11 arranged at intervals. The number of connectors 111 of each sub-valve body 11 may be the same or different. The connectors 111 are used for sleeving with the cooling pipelines on the corresponding equipment. Different sub-valve bodies 11 are independently arranged, that is, the multiple connectors 111 on the same sub-valve body 11 communicate with each other, and the connectors 111 on different sub-valve bodies 11 do not communicate with each other. The first fixing seat 12 may be integrally formed with each sub-valve body 11 to simplify the structural design. A connection hole 121 may be provided on the first fixing seat 12, and bolts pass through the connection hole 121 on the first fixing seat 12 to fix the multi-way valve assembly at a preset position.

[0028] In this embodiment, multiple sub-valve bodies 11 can be respectively connected to different cooling circuits. Specifically, each of the connectors 111 on the same sub-valve body 11 is respectively communicated with the corresponding cooling pipelines on the equipment in the same cooling circuit to realize the cooling circulation of the entire circuit. Since the sub-valve bodies 11 on different circuits are integrated with the first fixing seat 12, the first fixing seat 12 can be used to simultaneously fix the multiple sub-valve bodies 11. Compared with separately fixing the multi-way valves on different circuits, that is, the sub-valve bodies 11, the structure of the multi-way valve assembly of the present utility model is simpler, the fixed installation efficiency is higher, and the occupied space is smaller.

[0029] Optionally, the central axes of all the connectors 111 of at least two of the sub-valve bodies 11 are all located in the same plane. For example, as Figure 1 and Figure 3 shown, the central axes of the connectors 111 of each sub-valve body 11 are all located in the XZ plane. At this time, the space occupied by the valve body 1 in the Y direction can be reduced; in addition, compared with the valve body 1 in which the central axes of the respective connectors 111 are located in different planes, with this setting method, the forming and demolding of the valve body 1 are simpler.

[0030] Furthermore, the connection holes 121 on the first fixing seat 12 are perpendicular to the plane where the central axes of the respective connectors 111 are located, so that the installation and fixation of the valve body 1 are convenient.

[0031] As Figures 1 to 3 shown, optionally, at least two of the sub-valve bodies 11 include a first sub-valve body and a second sub-valve body. The first sub-valve body includes a first main pipe 116, and the second sub-valve body includes a second main pipe 117. The first main pipe 116 and the second main pipe 117 are parallel to each other, and the first fixing seat 12 is provided between them. The two ends of the first main pipe 116 and the second main pipe 117 are respectively provided with the connectors 111, and the remaining connectors 111 are arranged on the sides of the first main pipe 116 and the second main pipe 117 facing away from each other.

[0032] In this embodiment, there are two sub-valve bodies 11. The first sub-valve body can be connected to the engine cooling circuit in the vehicle thermal management system, and the second sub-valve body can be connected to the electric drive cooling circuit in the vehicle thermal management system. In this way, the cooling cycle of each circuit can be realized, and the installation space of the vehicle thermal management system can be saved.

[0033] As Figure 2 shown, the first main pipe 116 of the first sub-valve body and the second main pipe 117 of the second sub-valve body are arranged at intervals along the Z direction, and both the first main pipe 116 and the second main pipe 117 extend along the X direction. By arranging the connectors 111 at both ends of the first main pipe 116 of the first sub-valve body and on the side of the first main pipe 116 away from the second main pipe 117, and arranging the connectors 111 at both ends of the second main pipe 117 of the second sub-valve body and on the side of the second main pipe 117 away from the first main pipe 116, the cooling pipelines on different circuits are made to be as far away as possible to avoid interference. The first fixing seat 12 is arranged on the side where the first main pipe 116 of the first sub-valve body and the second main pipe 117 of the second sub-valve body are close to each other to optimize the space layout. The first fixing seat 12 can be fixedly installed on the engine.

[0034] Of course, in some other embodiments, the number of the sub-valve bodies 11 can also be three or more.

[0035] AsFigure 1 and Figure 3 As shown in Figure 3 , optionally, each of the plurality of connectors 111 of each sub-valve body 11 includes a liquid inlet connector 112 and a liquid outlet connector 113. A plurality of the liquid outlet connectors 113 are provided on at least one of the sub-valve bodies 11, and a flow-limiting protrusion 1131 is provided on the inner wall of some of the plurality of liquid outlet connectors 113.

[0036] Specifically, the first sub-valve body may have three connectors 111, one of which is a liquid inlet connector 112 and the other two are liquid outlet connectors 113. The second sub-valve body may have three connectors 111, two of which are liquid inlet connectors 112 and the other one is a liquid outlet connector 113. The first sub-valve body may have an inverted T-shaped structure, and the second sub-valve body may have a normal T-shaped structure.

[0037] A flow-limiting protrusion 1131 is provided on one of the two liquid outlet connectors 113 of the first sub-valve body. The flow-limiting protrusion 1131 may be an annular protrusion. By providing the flow-limiting protrusion 1131, the flow resistance of the liquid flowing through the liquid outlet connector 113 is increased, and the flow rate is reduced. When the coolant entering from the liquid inlet connector 112 is certain, by reducing the flow rate of one of the liquid outlet connectors 113, the flow rate of the other liquid outlet connector 113 can be increased, so that the flow rates of the two liquid outlet connectors 113 are different. Then, according to the heat dissipation requirements of different devices, the liquid outlet connector 113 with a larger flow rate is connected to the cooling pipeline on the device with a larger heat dissipation requirement, and the liquid outlet connector 113 with a smaller flow rate is connected to the cooling pipeline on the device with a smaller heat dissipation requirement, so as to realize the separate heat dissipation of different devices and improve the heat dissipation efficiency of the whole vehicle.

[0038] In some embodiments, a certain sub-valve body 11 is provided with three or more liquid outlet connectors 113. At this time, a flow-limiting protrusion 1131 can be provided on the inner wall of one or more of the liquid outlet connectors 113.

[0039] It should be noted that in this embodiment, the flow rate is reduced by providing the flow-limiting protrusion 1131 inside the liquid outlet connector 113, and the external shape of the liquid outlet connector 113 is not changed, which will not affect the connection between the multi-way valve assembly and each cooling pipeline.

[0040] As Figures 1-3 shown in Figures 1-3 , optionally, the multi-way valve assembly further includes a temperature detection device 2, and the temperature detection device 2 is installed on at least one of the sub-valve bodies 11.

[0041] In this embodiment, the temperature detection device 2 may be a temperature sensor. By providing the temperature detection device 2 on the corresponding sub-valve body 11, the temperature of the liquid flowing through the corresponding sub-valve body 11 can be monitored in real time, so as to take corresponding measures in time when the temperature is too high or too low.

[0042] Optionally, at least one of the sub-valve bodies 11 is provided with a second fixing seat 13. The second fixing seat 13 is provided with a fixing hole 131 communicating with the inside of the sub-valve body 11. One end of the temperature detection device 2 passes through the fixing hole 131 and is inserted into the corresponding sub-valve body 11.

[0043] Specifically, the second fixing seats 13 can be provided on each sub-valve body 11, or can be provided on some of the sub-valve bodies 11. The second fixing seat 13 can be integrally formed with the corresponding sub-valve body 11. The fixing hole 131 can be matched with the outer shape of the temperature detection device 2. The temperature detection device 2 is placed in the fixing hole 131 and one end of it is inserted into the corresponding sub-valve body 11 to measure the temperature of the liquid flowing in a single sub-valve body 11, so as to take corresponding measures in time when the temperature is too high or too low.

[0044] As Figures 1-2 shown, optionally, the multi-way valve assembly further includes an elastic clamping member 3. Two clamping holes 132 are provided on the circumferential side wall of the second fixing seat 13 at intervals in the circumferential direction. The clamping holes 132 communicate with the fixing hole 131. The elastic clamping member 3 includes two clamping arms 31 arranged oppositely and a connecting arm 32 connecting the two clamping arms 31. The two clamping arms 31 respectively pass through the corresponding clamping holes 132 to clamp the temperature detection device 2.

[0045] Specifically, two circumferentially extending arc-shaped clamping holes 132 are provided at intervals in the circumferential direction of the second fixing seat 13. The circumferential direction mentioned here refers to the direction around the central axis of the fixing hole 131. The circumferential side wall of the second fixing seat 13 is the side wall enclosing the fixing hole 131. The elastic clamping member 3 can be generally U-shaped. The clamping arm 31 is a bent structure. The clamping arm 31 can undergo elastic extrusion deformation. One end of each of the two clamping arms 31 is connected to the connecting arm 32. The distance between the other ends of the two clamping arms 31 can be slightly smaller than the radial dimension of the temperature detection device 2, so that after the two clamping arms 31 respectively pass through the clamping holes 132, they can form a clamping posture for the temperature detection device 2 to stably clamp the temperature detection device 2 on the second fixing seat 13.

[0046] It should be noted that taking the example of providing the second fixing seat 13 above one of the sub-valve bodies 11, the second fixing seat 13 is provided with a fixing hole 131 penetrating vertically. A sealing structure is provided inside the fixing hole 131. The sealing structure is located below the clamping hole 132. One end of the temperature detection device 2 passes downward through the sealing structure to extend into the sub-valve body 11. The sealing structure can be used to realize the sealed connection between the temperature detection device 2 and the fixing hole 131, and prevent the liquid in the sub-valve body 11 from flowing out between the temperature detection device 2 and the hole wall of the fixing hole 131.

[0047] As Figure 1As shown, optionally, an anti - detachment boss 114 is provided on the outer wall of at least one of the connectors 111; and / or, an anti - slip groove 115 is provided on the outer wall of at least one of the connectors 111.

[0048] Specifically, the anti - detachment boss 114 can be provided on the outer wall of some of the connectors 111, or can be provided on the outer walls of all the connectors 111. The anti - detachment boss 114 can be an annular boss. The anti - slip groove 115 can include multiple grooves arranged in sequence along the axial direction of the connector 111. The setting mode of the anti - slip groove 115 is similar to that of the anti - detachment boss 114, both being annular.

[0049] In this embodiment, the cooling pipeline is sleeved at the corresponding connector 111. Through the anti - slip effect of the anti - detachment boss 114 and / or the anti - slip groove 115, the cooling pipeline can be stably fixed at the connector 111 and will not become detached.

[0050] As Figure 4 shown, another embodiment of the present invention proposes a vehicle thermal management system, including a plurality of first cooling pipelines, a plurality of second cooling pipelines and the above - mentioned multi - way valve assembly. The multi - way valve assembly includes two sub - valve bodies. Each connector of one sub - valve body is respectively communicated with the corresponding first cooling pipeline, and each connector of the other sub - valve body is respectively communicated with the corresponding second cooling pipeline. The advantages of the vehicle thermal management system compared with the prior art are the same as those of the above - mentioned multi - way valve assembly, and will not be repeated here.

[0051] As Figure 4 shown, optionally, the plurality of first cooling pipelines are respectively a first water pump pipeline, a TOC cooling pipeline 5 and a WCAC cooling pipeline 6, and the plurality of second cooling pipelines are respectively a second water pump pipeline, an ODP cooling pipeline 9 and an ADCU cooling pipeline 101. The vehicle thermal management system further includes a first water pump 4, a second water pump 7, a third water pump 8 and a three - way valve 10. Each connector 111 of one sub - valve body 11 is respectively communicated with the first water pump pipeline, the TOC cooling pipeline 5 and the WCAC cooling pipeline 6, and the first water pump pipeline is communicated with the first water pump 4; each connector 111 of the other sub - valve body 11 is respectively communicated with the second water pump pipeline, the ODP cooling pipeline 9 and the first end of the three - way valve 10. The second water pump pipeline is communicated with the second water pump 7. The third water pump 8 is connected between the second end of the three - way valve 10 and the ODP cooling pipeline 9, and the ADCU cooling pipeline 101 is connected between the third end of the three - way valve 10 and the second water pump 7.

[0052] In this embodiment, TOC is the Transmission Oil Cooler, WCAC is the Water charge air cooler, ODP is the integrated vehicle power management module, and ADCU is the Autonomous Driving Control Unit. The TOC cooling pipeline 5 refers to the cooling pipeline arranged on the TOC for dissipating heat from the TOC; the WCAC cooling pipeline 6 refers to the cooling pipeline arranged on the WCAC for dissipating heat from the WCAC; the ODP cooling pipeline 9 refers to the cooling pipeline arranged on the ODP for dissipating heat from the ODP; the ADCU cooling pipeline 101 refers to the cooling pipeline arranged on the ADCU for dissipating heat from the ADCU.

[0053] The two sub-valves 11 of the multi-way valve assembly are respectively the first sub-valve and the second sub-valve. The first sub-valve has one liquid inlet joint 112 and two liquid outlet joints 113. The liquid inlet joint 112 of the first sub-valve is connected to the first water pump 4 through the first water pump pipeline. One of the liquid outlet joints 113 of the first sub-valve is communicated with the WCAC cooling pipeline 6, and the other liquid outlet joint 113 is communicated with the TOC cooling pipeline 5. The coolant flowing out from the TOC cooling pipeline 5 and the WCAC cooling pipeline 6 flows to the first radiator 102, and after being cooled by the first radiator 102, it flows back to the first water pump 4 to realize the circulating flow of the coolant in the engine cooling circuit.

[0054] Here, the heat dissipation requirement of the WCAC is relatively large, and the heat dissipation requirement of the TOC is relatively small. The TOC cooling pipeline 5 can be connected to the liquid inlet joint 112 provided with a flow-limiting protrusion 1131 to reduce the coolant flow rate entering the TOC cooling pipeline and increase the coolant flow rate entering the WCAC cooling pipeline 6.

[0055] The second sub-valve has two liquid inlet joints 112 and one liquid outlet joint 113. The coolant output by the second water pump 7 enters the second radiator 103 through the second water pump pipeline. After being cooled by the second radiator 103, it enters from one of the liquid inlet joints 112 of the second sub-valve. After the liquid outlet joint 113 of the second sub-valve is communicated with the three-way valve 10, on the one hand, it is connected to the second water pump 7 through the sequentially arranged ADCU cooling pipeline 101, and on the other hand, it is communicated with the other liquid inlet joint 112 of the second sub-valve through the sequentially arranged third radiator 104, the third water pump 8 and the ODP cooling pipeline 9, so as to realize the circulating flow of the coolant in the electric drive cooling circuit.

[0056] Another embodiment of the present utility model further proposes a vehicle, including the above-mentioned vehicle thermal management system. The advantages of the vehicle compared with the prior art are the same as those of the above-mentioned vehicle thermal management system, and will not be repeated here.

[0057] Although the present utility model is disclosed as above, the protection scope of the present utility model is not limited thereto. Without departing from the spirit and scope of the present utility model, those skilled in the art can make various changes and modifications, and these changes and modifications will all fall within the protection scope of the present utility model.
