The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application and cannot be understood as limiting the present application.

The thermal management system 100 according to the embodiment of the present application will be described below with reference to the accompanying drawings.

As shown in FIG. 1 , according to the thermal management system 100 according to the embodiment of the present application, the thermal management system 100 includes: a multi-channel switching valve 10 , a water tank 20 and a water pump 30 .

The multi-channel switching valve 10 includes a housing 11 and a valve core 12. The housing 11 is provided with a first connection valve port 111 and a plurality of second connection valve ports 112. The housing 11 is provided with a first chamber and a second chamber. 114 and flow channel 115. The second chamber 114 is provided with a water flow channel 1141 connected with the first chamber. The first connection valve port 111 is connected with the first chamber, and a plurality of second connection valve ports 112 are connected with the second chamber. Room 114 is connected.

Among them, the thermal management system 100 manages the heat exchange medium, which circulates in the first connection valve port 111, the second connection valve port 112, the first chamber, the second chamber 114, the flow channel 115, and the water flow channel 1141. . As shown in Figure 1 (the bold line in Figure 1 is the flow path of the heat exchange medium), the heat exchange medium can enter the second chamber 114 from the second connection valve port 112, and then enter the first chamber through the water flow channel 1141, and then flows out from the first connection valve port 111.

The valve core 12 is rotatably disposed in the second chamber 114. The valve core 12 is provided with at least one first switching channel 121, and each first switching channel 121 is configured to communicate with the water flow channel 1141 and one of the second connection valve ports. 112. The rotation of the valve core 12 causes the water flow channel 1141 to switch and communicate with at least two second connection valve ports 112. By providing the rotatable valve core 12, and the first switching channel 121 is provided on the valve core 12, the first connection valve The port 111 can be switched and connected with different second connection valve ports 112 to realize the concentration of various pipeline functions and improve the integration level. For example, vehicles usually have a motor cooling circuit and a battery cooling circuit. In the initial state, the valve core 12 connects the first connection valve port 111 with a second connection valve port 112, and the motor cooling circuit operates to cool the motor; then the valve core 12 connects the first connection valve port 111 with a second connection valve port 112. 12 rotates to connect the first connection valve port 111 with another second connection valve port 112, and the battery cooling circuit operates to cool the battery; of course, the above is only an example and does not represent a limitation on the content of the present application. For convenience of description, in the following, the heat exchange medium flows out of the thermal management system 100 from the first connection valve port 111 and flows into the thermal management system 100 from the second connection valve port 112 as an example.

The rotation of the valve core 12 causes the water flow channel 1141 to switch and communicate with at least two second connection valve ports 112 . That is to say, the water flow channel 1141 can be switched and connected with two second connection valve ports 112. For example, the water flow channel 1141 can be connected with one second connection valve port 112 in the initial state, and then the valve core 12 rotates so that the water flow channel 1141 Communicated with another second connection valve port 112 . Alternatively, the water flow channel 1141 may be in switching communication with three second connection valve ports 112. For example, the water flow channel 1141 may be in communication with the first second connection valve port 112 in the initial state, and the valve core 12 rotates so that the water flow channel 1141 In communication with the second second connection valve port 112, the valve core 12 rotates again so that the water flow channel 1141 communicates with the third second connection valve port 112.

The water tank 20 and the shell 11 are independent molded parts. The water tank 20 is assembled to the shell 11. The water outlet of the water tank 20 is connected with the flow channel 115. The heat exchange medium flowing out from the water tank 20 flows to the first chamber or the second chamber 114. By arranging the water outlet of the water tank 20 to communicate with the flow channel 115, the heat exchange medium flowing out from the water tank 20 flows to the first chamber. The water tank 20 can replenish water in the first chamber and maintain the state of the heat exchange medium in the first chamber. Stablize. Alternatively, the heat exchange medium flowing out from the water tank 20 flows to the second chamber 114, and the second chamber 114 can guide the heat exchange medium to other spaces to complete the circulation of the heat exchange medium in the water tank 20. Among them, the water tank 20 is assembled to the casing 11. Compared with the technical solution of installing sub-parts in different positions in the related art, the integration level is improved and the cost is reduced.

The water pump 30 is installed to the housing 11. The water pump 30 operates to provide power for liquid flow in the first chamber. By installing the water pump 30 to the housing 11, the components are centrally arranged and the overall space is saved.

According to the thermal management system 100 of the embodiment of the present application, a multi-channel switching valve 10 is provided, and the housing 11 of the multi-channel switching valve 10 is integrated with a water tank 20 and a water pump 30. Compared with the multiple pipelines and multiple water pumps in the related art, The method of pipe joints and multiple fixed brackets has a higher degree of integration, improves space utilization, and reduces costs; at the same time, by setting the water outlet of the water tank 20 to connect with the flow channel 115, multiple functions can be completed.

In some embodiments, the thermal management system 100 also includes a seal 13. The seal 13 is provided on the valve core 12 and is used to seal the switching channels on the valve core 12 to ensure that the switching channels do not communicate with each other.

As shown in Figures 1 and 3, in some embodiments, there are multiple water pumps 30, each water pump 30 is provided with a first chamber, and each first chamber communicates with the second chamber 114 through a water flow channel 1141. Communicated, each water flow channel 1141 is switched and communicated with at least two second connection valve ports 112 through the first switching channel 121 .

For example, there are two water pumps 30, and the two water pumps 30 correspond to the two first chambers, so that the liquid in the two first chambers can flow. The vehicle is usually equipped with a motor cooling circuit and a battery cooling circuit, and the motor cooling circuit and the battery The cooling circuits respectively correspond to a first chamber, so that the motor cooling circuit and the battery cooling circuit can operate simultaneously. Of course, there can also be a larger number of water pumps 30 , and the specific number can be set according to the internal circuit of the vehicle, which will not be described again here.

Specifically, there are multiple first chambers, and the multiple first chambers are isolated from each other. The multiple first chambers are connected to different first connection valve ports 111 respectively. Each first chamber also corresponds to a water flow channel 1141. Each water flow channel 1141 is switched and communicated with at least two second connection valve ports 112 through the first switching channel 121, that is, each first connection valve port 111 is switched with at least two second connection valve ports 112 through the first switching channel 121. Connected.

For example, there are two first connection valve ports 111 , the two first connection valve ports 111 are the first connection valve port A and the first connection valve port B respectively, the number of the second connection valve ports 112 is three, and the three second connection valve ports 111 are respectively. The connecting valve ports 112 are respectively the second connecting valve port A, the second connecting valve port B and the second connecting valve port C. There are two first chambers, and the two first chambers are respectively the first chamber A and the second connecting valve port. One chamber B has two water flow channels 1141. The two water flow channels 1141 are respectively water flow channel A and water flow channel B. The first connecting valve port A is connected to the first chamber A, and the first chamber A is connected to the water flow channel A. Communicated, the first connection valve port B is connected to the first chamber B, the first chamber B is connected to the water flow channel 1141B, the water flow channel A and the water flow channel B are connected to the same second chamber 114, and the second chamber 114 A valve core 12 is provided inside, and the valve core 12 is provided with two first switching channels 121. The two first switching channels 121 are the first switching channel A and the first switching channel B respectively. In the initial state, water flow channel A is connected to the second connection valve port A through the first switching channel A, and water flow channel B is connected to the second connection valve port B through the first switching channel B; then the valve core 12 rotates to change the first switching channel 121 position, so that the water flow channel A is connected to the second connection valve port B through the first switching channel B, and the water flow channel B is connected to the second connection valve port C through the first switching channel A, thereby controlling the flow path of the heat exchange medium.

As shown in Figures 1 and 5 (the thick black line in Figure 5 is the flow path of the heat exchange medium), in some embodiments, the flow channel 115 is located outside the second chamber 114 and at the lower end of the flow channel 115 Extending to communicate with the water flow channel 1141, the flow channel 115 is located outside the second chamber 114 to prevent the two flow channels from interfering with each other and make the flow path of the thermal management system 100 clearer.

As shown in Figure 2, in some embodiments, the outlet end of the flow channel 115 is located on the inner wall of the second chamber 114, the valve core 12 is also provided with a second switching channel 122, and the valve core 12 rotates so that the second switching channel 122 The flow channel 115 and the water flow channel 1141 are simultaneously connected, or the valve core 12 rotates so that the second switching channel 122 is disconnected from at least one of the flow channel 115 and the water flow channel 1141, further increasing the flow path and increasing options. Among them, the rotation of the valve core 12 makes the second switching channel 122 communicate with the flow channel 115 and the water flow channel 1141 at the same time, so that the liquid in the water tank 20 enters the second switching channel 122 through the flow channel 115, and the second switching channel 122 guides the liquid. The water flow channel 1141 is connected to the first chamber, and the first chamber is connected to the first connection valve port 111. Finally, the liquid in the water tank 20 flows out from the first connection valve port 111; the rotation of the valve core 12 causes the second switching channel 122 is disconnected from at least one of the flow channel 115 and the water flow channel 1141 to disconnect the above-mentioned flow path and stop the liquid in the water tank 20 from flowing out of the first connection valve port 111.

The water tank 20 is provided with a water inlet for injecting liquid into the water tank 20. An external pipeline is connected to the water inlet for supplying liquid. The liquid supplied by the external pipeline can flow out from the first connection valve port 111 to form a complete circulation path.

As shown in FIGS. 1 and 5 , in some embodiments, the flow channel 115 extends to the top wall of the housing 11 , the water tank 20 is supported on the housing 11 , and the water outlet is inserted into the flow channel 115 . That is to say, the water tank 20 is arranged above the housing 11, so that the heat exchange medium in the water tank 20 can enter the flow channel 115 under the action of its own gravity, and the heat exchange medium can be automatically replenished.

As shown in Figures 1 and 3, in some embodiments, multiple second connection valve ports 112 are located on the same side of the housing 11. By arranging the multiple second connection valve ports 112 on the same side of the housing 11, It facilitates the connection of multiple second valve ports with external pipelines and improves efficiency. It can be understood that multiple second connection valve ports 112 are provided on the same side of the housing 11. When installing external pipelines to the second connection valve ports 112, they only need to face one side of the housing 11 for installation. There is no need to change the direction of the multi-channel switching valve 10 . For example, three second connection valve ports 112 are provided on the front side. When installing external pipelines to the second connection valve ports 112 , the installer only needs to face the front side of the multi-channel switching valve 10 .

In some embodiments, multiple second connection valve ports 112 are located on different sides of the housing 11, adding more choices to the user, and the external pipeline does not need to be twisted, making the direction of the external pipeline clearer.

As shown in FIG. 1 , in some embodiments, the first connection valve port 111 and the second connection valve port 112 are located on opposite sides of the housing 11 . Opposite sides of the body 11, reducing the probability of installation errors. Both the first connection valve port 111 and the second connection valve port 112 need to be connected to external pipelines, but the functions of the first connection valve port 111 and the second connection valve port 112 are different. If the first connection valve port 111 should be installed on Installing the external pipeline on the second connection valve port 112 will inevitably cause damage. In this application, the first connection valve port 111 and the second connection valve port 112 are located on opposite sides to avoid the first connection valve port 111 and the second connection valve port 112. The problem of incorrect installation when the two connecting valve ports 112 are installed on the same side improves safety.

For example, the second connection valve port 112 is located on the front side of the housing 11, and the first connection valve port 111 is located on the rear side of the housing 11. When installing the external pipeline to the second connection valve port 112, first face the front side. The first connection valve port 111 is installed on the side, and then faces the rear side. The installer can easily identify the first connection valve port 111 and the second connection valve port 112 through the front and rear directions.

In some embodiments, the first connection valve port 111 and the second connection valve port 112 are located on the same side of the housing 11. By arranging the first connection valve port 111 and the second connection valve port 112 on the same side of the housing 11, Easy to install. Both the first connection valve port 111 and the second connection valve port 112 need to be connected to external pipelines. When the external pipelines are installed on the first connection valve port 111 and the second connection valve port 112, the first connection on the same side The valve port 111 and the second connecting valve port 112 allow the installer to complete the installation in situ without changing the position. Of course, it can be understood that the placement positions of the first connection valve port 111 and the second connection valve port 112 are not limited to the above situation, and can be limited according to the actual situation.

Specifically, the housing 11 includes a body and a cover plate. The valve core 12 is disposed in the body, and the cover plate is disposed on the body. The control module 40 can be disposed on the body or the cover plate. For example, the control module 40 is provided on the body to increase stability; or the control module 40 is provided on the cover to facilitate installation.

As shown in FIGS. 1 , 3 and 4 , in some embodiments, the control module 40 and the water tank 20 are distributed on opposite sides of the housing 11 . On the other hand, the components are dispersedly distributed on the casing 11 to reduce the problem of inconvenient circuit connections caused by the concentration of components. At the same time, the center of gravity is placed on the casing 11 to stabilize the thermal management system 100.

As shown in Figures 1, 3 and 4, in some embodiments, the thermal management system 100 further includes a heat exchanger 50. The heat exchanger 50 is fixed to the housing 11 and/or the water tank 20. By disposing the heat exchanger 50 Provide heat exchange space for other devices to facilitate cooperation with other components. For example, the heat exchanger 50 is fixed to the shell 11, and the integration method is more flexible; or the heat exchanger 50 is fixed to the water tank 20, and the water tank 20 is larger, making the installation of the heat exchanger more convenient.

In some embodiments, the housing 11 is provided with a mounting portion, and the mounting portion is used to connect to the vehicle body. By providing the mounting portion, the difficulty of installing the housing 11 to the vehicle body is reduced, and production efficiency is improved.

As shown in Figure 1, specifically, at least one first switching channel 121 includes an inner flow channel 1211 and two communication ports 1212. The inner flow channel 1211 is provided inside the valve core 12, and the two communication ports 1212 are located inside the valve core 12. 12, both ends of the inner flow channel 1211 are connected with two communication ports 1212 respectively. By setting the inner flow channel 1211, the space occupied by the valve core 12 is fully utilized, and multiple first connecting valve ports 111 and The plurality of second connection valve ports 112 switch the connection mode to increase the adaptability to different vehicles 1000 .

In some embodiments, at least one first switching channel 121 includes an outer flow channel extending along the outer peripheral wall of the valve core 12 , and the outer flow channel is used to connect the water flow channel 1141 with one of the second connecting valve ports. 112. On the basis of setting the inner flow channel 1211 inside the valve core 12, the number of selectable modes is further increased to meet more various working needs.

Among them, the inner flow channel 1211 is provided inside the valve core 12 to allow the second connection valve port 112 to communicate with the water flow channel 1141 in complex situations. For example, multiple second connection valve ports 112 and multiple water flow channels 1141 are combined into a With the sixteen openings arranged in 4X4, the second connecting valve port 112 on the diagonal line and the water flow channel 1141 are directly connected through the outer flow channel on the outer peripheral wall of the valve core 12, which will inevitably affect the second connections on both sides of the diagonal line. As for the connection between the valve port 112 and the water flow channel 1141, by locating the inner flow channel 1211 inside the valve core 12, this problem can be avoided and the design difficulty of the valve core 12 can be reduced.
