[0037] Existing thermal management systems for new energy vehicles use circulating water for heat exchange as a temperature control method. This heat exchange circuit requires a relatively large number of control valves and connectors, primarily three-way and four-way valves, and two-way and three-way connectors.
[0038] Due to the large number of control valves and connectors used, the number of required pipelines increases, which increases energy loss. In addition, more control signals are required to match the corresponding control valves. The entire thermal management system occupies more space in the vehicle and is more expensive.
[0039] To this end, the present application provides a waterway integrated valve 1000 . Figure 1 Schematic diagram of a waterway integrated valve 1000 provided according to one embodiment of the present application. Figure 2 for Figure 1 Exploded view of the intermediate water circuit integrated valve 1000. Figure 3 for Figure 1 A cross-sectional view of the waterway integrated valve 1000.
[0040] See also Figures 1 to 3 The waterway integrated valve 1000 includes a multi-way valve 100 and a housing assembly 200. The housing assembly 200 includes an outer shell 210 and a plurality of internal flow channels 220. The outer shell 210 is provided with a plurality of external interfaces 211.
[0041] The multi-way valve 100 is partially disposed within the outer housing 210 and includes a plurality of internal ports 111 within the outer housing 210. The multi-way valve 100 is configured to switch the communication relationship between the plurality of internal ports 111. An internal flow channel 220 is disposed within the outer housing 210 and connects one internal port 111 to at least one external port 211.
[0042] In this embodiment, the water channel integrated valve 1000 is composed of a multi-way valve 100 and a shell assembly 200, wherein the shell assembly 200 is composed of an outer shell 210 and multiple internal flow channels 220, each internal flow channel 220 is located in the outer shell 210 and connected between the multi-way valve 100 and the inner circumferential wall of the outer shell 210, so as to connect the external interface 211 on the outer shell 210 with the internal interface 111 on the multi-way valve 100.
[0043] Each internal port 111 of the multi-way valve 100 is located within the outer housing 210. Each internal port 111 of the multi-way valve 100 is connected to each external port 211 of the outer housing 210 via a corresponding internal flow channel 220. The multi-way valve 100 can switch the communication relationship between each internal port 111, thereby switching the communication relationship between each external port 211.
[0044] It should be noted that each external port 211 can connect to different hot water exchange circuits, such as a battery hot water exchange circuit, a motor hot water exchange circuit, a heat dissipation circuit, and a heating circuit. By controlling the connectivity of each internal port 111 of the multi-way valve 100, the connectivity of the hot water exchange circuits connected to each external port 211 can be switched to form circuits with different functions. For example, connecting the battery hot water exchange circuit to the heat dissipation circuit forms a battery heat dissipation circuit, while connecting the battery heat dissipation circuit to the heating circuit forms a battery heating circuit.
[0045] It can be seen that the water channel integrated valve 1000 integrates a multi-way valve 100 and multiple internal flow channels 220. By controlling a multi-way valve 100, the connectivity relationship of multiple water exchange water channels connected to multiple external interfaces 211 can be switched to achieve different functions, thereby reducing the amount of control signals required for the vehicle.
[0046] Furthermore, because the integrated water valve 1000 can be shared by multiple different heat exchange circuits, it can reduce the number of control valves and pipe joints used, the number of pipes required, and energy loss and costs. Consequently, a vehicle thermal management system utilizing the integrated water valve 1000 requires less space in the vehicle.
[0047] In a further optional embodiment, the multi-way valve 100 includes an inner valve body 110 and a flow channel switching assembly 120. The inner valve body 110 is arranged in the outer shell 210 and is provided with multiple internal interfaces 111. The flow channel switching assembly 120 is connected to the inner valve body 110 to switch the connection relationship between each internal interface 111.
[0048] In this embodiment, the portion of the multi-way valve 100 disposed within the outer shell 210 is the inner valve body 110 , the inner ports 111 are all integrated on the inner valve body 110 , and the connectivity between the inner ports 111 is controlled by the flow channel switching assembly 120 .
[0049] exist Figure 3 In the illustrated embodiment, the inner valve body 110 and the outer valve body 210 are both cylindrical in shape. The inner valve body 110 and the outer valve body 210 are connected by a plurality of internal flow channels 220 arranged at circumferential intervals. Each internal flow channel 220 extends from a corresponding inner port 111 and is connected to a corresponding outer port 211, thereby connecting each inner port 111 with a corresponding outer port 211.
[0050] In a further optional embodiment, the flow channel switching assembly 120 includes a rotating shaft 121, a vane 122, and a rotating shaft control module 123. The vane 122 is disposed within the inner valve body 110, and the rotating shaft 121 is connected to the vane 122. The rotating shaft control module 123 is disposed outside the outer housing 210 and is used to start and stop the rotating shaft 121, thereby driving the vane 122 to change position and achieve switching of the communication relationship between the multiple internal ports 111.
[0051] In this embodiment, the flow channel switching assembly 120 comprises a rotating shaft 121, a blade 122, and a rotating shaft control module 123. The blade 122 is fixedly connected to the rotating shaft 121 and can rotate with the rotating shaft 121. The rotating shaft control module 123 can drive the rotating shaft 121 to rotate and control the stopping position of the rotating shaft 121, thereby changing the position of the blade 122 within the inner valve body 110.
[0052] It should be noted that changing the position of the blade 122 can switch the communication relationship between different internal ports 111. In a further optional embodiment, the blade 122 includes a first blade 1221 and a second blade 1222. The first blade 1221 and the second blade 1222 are located on either side of the rotating shaft 121 and divide the inner valve body 110 into multiple internal flow channel areas A, which are used to connect different internal ports 111.
[0053] In this embodiment, there are two blades 122, namely a first blade 1221 and a second blade 1222. The first blade 1221 and the second blade 1222 cooperate to divide the internal space of the inner valve body 110 into multiple sealed internal flow channel areas A. Each internal flow channel area A allows fluid medium to pass through, thereby connecting different internal ports 111, and correspondingly connecting different internal ports 111 to corresponding different external ports 211.
[0054] In a specific application, the shaft control module 123 may include a drive unit and a control unit. The drive unit is used to drive the shaft 121 to rotate, and the control unit controls the drive unit to control the start and stop positions of the shaft 121, thereby changing the position of the blades 122. Here, the drive unit can be a motor, etc., and the control unit can be a single-chip microcomputer, a control circuit, etc.
[0055] In some optional embodiments, the plurality of internal flow channels 220 include a first internal flow channel 221 and a second internal flow channel 222. The first internal flow channel 221 connects one internal port 111 to a corresponding external port 211, and the second internal flow channel 222 connects one internal port 111 to a plurality of corresponding external ports 211.
[0056] In this embodiment, the first internal flow channel 221 is a two-way connector, realizing a one-to-one interface connection structure, and the second internal flow channel 222 is a multi-way connector, realizing a one-to-multiple interface connection structure.
[0057] In a further optional embodiment, there are two first internal flow channels 221, each of which connects one internal port 111 to a corresponding external port 211. There are three second internal flow channels 222, each of which connects one internal port 111 to two corresponding external ports 211.
[0058] In this embodiment, the second internal flow channels 222 are three three-way connectors, realizing a one-to-two interface connection structure. The number of the first internal flow channels 221 is limited to two.
[0059] In a further optional embodiment, the plurality of external interfaces 211 include a first external interface 2111 , a second external interface 2112 , a third external interface 2113 , a fourth external interface 2114 , a fifth external interface 2115 , a sixth external interface 2116 , a seventh external interface 2117 and an eighth external interface 2118 .
[0060] The two first internal flow channels 221 respectively connect the first external port 2111 with the corresponding internal port 111 and the sixth external port 2116 with the corresponding internal port 111 .
[0061] The three second internal flow channels 222 respectively connect one inner port 111 with the second outer port 2112 and the third outer port 2113 , one inner port 111 with the fourth outer port 2114 and the fifth outer port 2115 , and one inner port 111 with the seventh outer port 2117 and the eighth outer port 2118 .
[0062] In this embodiment, the number of the external interfaces 211 is 8, and the 8 external interfaces 211 are connected to the 5 internal interfaces 111 via the two first internal flow channels 221 and the three second internal flow channels 222 .
[0063] As can be seen from the above, the number of internal ports 111 corresponding to the multi-way valve 100 is 5. In other words, the multi-way valve 100 is a five-way valve.
[0064] In an optional embodiment, the multiple internal interfaces 111 include a first internal interface 1111 , a second internal interface 1112 , a third internal interface 1113 , a fourth internal interface 1114 and a fifth internal interface 1115 .
[0065] The plurality of inner flow channel regions A include a first inner flow channel region A1, a second inner flow channel region A2, and a third inner flow channel region A3. The blade 122 is configured to be rotatable to any one of a first position, a second position, a third position, and a fourth position.
[0066] Figure 4 A schematic diagram of the blade 122 in the first position is shown. Figure 4 In the first position, the first inner flow channel area A1 can connect the second inner interface 1112 with the third inner interface 1113, the second inner flow channel area A2 can connect the first inner interface 1111 with the fourth inner interface 1114, and the third inner flow channel area A3 is connected to the fifth inner interface 1115.
[0067] Thus, in the first position, the first external interface 2111 is connected to the sixth external interface 2116 , the second external interface 2112 , the third external interface 2113 , the fourth external interface 2114 and the fifth external interface 2115 are connected, and the seventh external interface 2117 is connected to the eighth external interface 2118 .
[0068] Figure 5 A schematic diagram of the blade 122 in the second position is shown. Figure 5 In the second position, the first inner flow channel area A1 can connect the first inner port 1111 with the fifth inner port 1115 , the second inner flow channel area A2 can connect the second inner port 1112 with the third inner port 1113 , and the third inner flow channel area A3 is connected to the fourth inner port 1114 .
[0069] Thus, in the second position, the first external interface 2111 , the seventh external interface 2117 , and the eighth external interface 2118 are connected, and the second external interface 2112 , the third external interface 2113 , the fourth external interface 2114 , and the fifth external interface 2115 are connected.
[0070] Figure 6 A schematic diagram of the blade 122 in the third position is shown. Figure 6 In the third position, the first inner flow channel area A1 can connect the third inner port 1113 and the fourth inner port 1114, the third inner flow channel area A3 can connect the first inner port 1111 and the second inner port 1112, and the second inner flow channel area A2 is connected to the fifth inner port 1115.
[0071] Thus, in the third position, the first external interface 2111 , the second external interface 2112 and the third external interface 2113 are connected, the fourth external interface 2114 , the fifth external interface 2115 and the sixth external interface 2116 are connected, and the seventh external interface 2117 and the eighth external interface 2118 are connected.
[0072] Figure 7 A schematic diagram of the blade 122 in the fourth position is shown. Figure 7 In the fourth position, the first inner flow channel area A1 can connect the third inner interface 1113 with the fourth inner interface 1114, the second inner flow channel area A2 is set to connect the second inner interface 1112 with the fifth inner interface 1115, and the third inner flow channel area A3 is connected to the first inner interface 1111.
[0073] Thus, at the fourth position, the second external interface 2112 , the third external interface 2113 , the seventh external interface 2117 , and the eighth external interface 2118 are connected, and the fourth external interface 2114 , the fifth external interface 2115 , and the sixth external interface 2116 are connected.
[0074] It can be seen that the waterway integrated valve 1000 is an eight-way valve formed by integrating a five-way valve, two two-way connectors and three three-way connectors.
[0075] It should be noted that the multi-way valve 100 is not limited to a five-way valve, and the types and numbers of connectors are not limited to the illustrated embodiment. The number of external interfaces 211 can be adjusted according to needs.
[0076] In some optional embodiments, the first to eighth external interfaces 2111 to 2118 are evenly spaced along the circumference of the outer shell 210 .
[0077] In this embodiment, any two adjacent external interfaces 211 form the same angle with the central axis of the outer shell 210 , thereby fully utilizing the peripheral space of the outer shell 210 and reducing the risk of pipeline interference when assembling pipelines on the external interfaces 211 .
[0078] In specific applications, each external interface 211 is a standard quick-plug interface component, which can quickly assemble pipelines and improve assembly efficiency.
[0079] Another aspect of the present application provides a vehicle thermal management system, which includes the aforementioned integrated waterway valve 1000. Clearly, a vehicle thermal management system utilizing this integrated waterway valve 1000 can reduce the number of control valves and connectors, and thus the number of pipelines, thereby lowering energy loss and costs. Accordingly, this vehicle thermal management system occupies less space within the vehicle's interior layout. Since only a single five-way valve needs to be controlled, the number of control signals required by the vehicle is reduced. Of course, this vehicle thermal management system also possesses other advantages brought about by the aforementioned integrated waterway valve 1000, which will not be reiterated here.
[0080] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Those skilled in the art can change, modify, replace and modify the above embodiments within the scope of the present application.
