[0032] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The thermal management system 100 of the present invention is described below with reference to the accompanying drawings.

[0034] like Figure 1 As shown, according to an embodiment of the present invention, the thermal management system 100 includes: a multi-channel switching valve 10, a water tank 20, and a water pump 30.

[0035] The multi-channel switching valve 10 includes a housing 11 and a valve core 12. The housing 11 is provided with a first connecting valve port 111 and a plurality of second connecting valve ports 112. The housing 11 is provided with a first chamber, a second chamber 114 and a flow path 115. The second chamber 114 is provided with a water flow path 1141 communicating with the first chamber. The first connecting valve port 111 is communicating with the first chamber, and the plurality of second connecting valve ports 112 are communicating with the second chamber 114.

[0036] The thermal management system 100 manages the heat exchange medium, which flows within the first connecting valve port 111, the second connecting valve port 112, the first chamber, the second chamber 114, the flow path channel 115, and the water flow channel 1141. For example... Figure 1 As shown ( Figure 1 (The thickened line represents the heat exchange medium flow path). The heat exchange medium can enter the second chamber 114 from the second connecting valve port 112, then enter the first chamber through the water flow channel 1141, and then flow out from the first connecting valve port 111.

[0037] The valve core 12 is rotatably disposed within the second chamber 114. The valve core 12 is provided with at least one first switching channel 121. Each first switching channel 121 is adapted to connect the water flow channel 1141 and one of the second connecting valve ports 112. Rotation of the valve core 12 causes the water flow channel 1141 to switch between at least two second connecting valve ports 112. By providing a rotatable valve core 12 with first switching channels 121, the first connecting valve port 111 can switch between different second connecting valve ports 112, thereby concentrating multiple pipeline functions and improving integration. For example, vehicles typically have a motor cooling circuit and a battery cooling circuit. In the initial state, the valve core 12 connects the first connecting valve port 111 to one second connecting valve port 112, and the motor cooling circuit operates to cool the motor. Then, the valve core 12 rotates to connect the first connecting valve port 111 to another second connecting 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 invention. For ease of description, the following text will use the example of the heat exchange medium flowing out of the heat management system 100 from the first connecting valve port 111 and flowing into the heat management system 100 from the second connecting valve port 112.

[0038] The valve core 12 rotates to switch the water flow channel 1141 with at least two second connection valve ports 112. That is, the water flow channel 1141 can switch between two second connection valve ports 112. For example, the water flow channel 1141 may initially be connected to one second connection valve port 112, and then the valve core 12 rotates to connect the water flow channel 1141 with another second connection valve port 112. Alternatively, the water flow channel 1141 can switch between three second connection valve ports 112. For example, the water flow channel 1141 may initially be connected to the first second connection valve port 112, the valve core 12 rotates to connect the water flow channel 1141 with the second second connection valve port 112, and the valve core 12 rotates again to connect the water flow channel 1141 with the third second connection valve port 112. Of course, the water flow channel 1141 can also switch between four, five, or more second connection valve ports 112 to improve integration.

[0039] The water tank 20 and the shell 11 are independently molded parts. The water tank 20 is assembled to the shell 11. The outlet of the water tank 20 is connected to the flow channel 115. The heat exchange medium flowing out of the water tank 20 flows to either the first chamber or the second chamber 114. By connecting the outlet of the water tank 20 to the flow channel 115, the heat exchange medium flowing out of the water tank 20 can flow to the first chamber, allowing the water tank 20 to replenish water and maintain the stability of the heat exchange medium within the first chamber. Alternatively, the heat exchange medium flowing out of the water tank 20 can flow to the second chamber 114, which can guide the heat exchange medium to other spaces, completing the circulation of the heat exchange medium within the water tank 20. The water tank 20 is assembled to the shell 11, which, compared to related technologies where sub-parts are installed in different locations, improves integration and reduces costs.

[0040] The water pump 30 is installed in the housing 11. The water pump 30 operates to provide power for the flow of liquid in the first chamber. By installing the water pump 30 in the housing 11, the components are arranged in a centralized manner, saving overall space.

[0041] The thermal management system 100 according to an embodiment of the present invention has a higher degree of integration, improves space utilization, and reduces costs by setting a multi-channel switching valve 10, and integrating a water tank 20 and a water pump 30 on the housing 11 of the multi-channel switching valve 10. Compared with the related art, which uses multiple pipelines, multiple pipeline joints and multiple fixed supports, the system has a higher degree of integration. At the same time, by setting the outlet of the water tank 20 to be connected to the flow channel 115, it can perform multiple functions.

[0042] In some embodiments, the thermal management system 100 further includes a seal 13 disposed on the valve core 12 for sealing the switching channels on the valve core 12 to ensure that the switching channels do not flow to each other.

[0043] like Figure 1 , Figure 3 As shown, in some embodiments, there are multiple water pumps 30, each water pump 30 is provided with a first chamber, each first chamber is connected to a second chamber 114 through a water flow channel 1141, and each water flow channel 1141 is switched to be connected to at least two second connecting valve ports 112 through a first switching channel 121.

[0044] For example, there are two water pumps 30, each corresponding to one of the two first chambers, allowing liquid to flow in both chambers. Vehicles typically have a motor cooling circuit and a battery cooling circuit, each corresponding to one first chamber, enabling simultaneous operation of both circuits. Of course, there can be more water pumps 30; the specific number can be determined based on the vehicle's internal circuitry, which will not be elaborated upon here.

[0045] Specifically, there are multiple first chambers, which are isolated from each other. Each of the multiple first chambers is connected to different first connection valve ports 111. Each first chamber also corresponds to a water flow channel 1141. Each water flow channel 1141 is switched to be connected to at least two second connection valve ports 112 through a first switching channel 121. That is, each first connection valve port 111 is switched to be connected to at least two second connection valve ports 112 through a first switching channel 121.

[0046] For example, there are two first connecting valve ports 111, namely first connecting valve port A and first connecting valve port B; there are three second connecting valve ports 112, namely second connecting valve port A, second connecting valve port B and second connecting valve port C; there are two first chambers, namely first chamber A and first chamber B; there are two water flow channels 1141, namely water flow channel A and water flow channel B; first connecting valve port A is connected to first chamber A and first chamber A is connected to water flow channel A; first connecting valve port B is connected to first chamber B and first chamber B is connected to water flow channel 1141B; water flow channel A and water flow channel B are connected to the same second chamber 114; a valve core 12 is provided in the second chamber 114; the valve core 12 is provided with two first switching channels 121, namely first switching channel A and first switching channel B. In the initial state, water flow channel A is connected to the second connecting valve port A through the first switching channel A, and water flow channel B is connected to the second connecting valve port B through the first switching channel B; then the valve core 12 rotates to change the position of the first switching channel 121, so that water flow channel A is connected to the second connecting valve port B through the first switching channel B, and water flow channel B is connected to the second connecting valve port C through the first switching channel A, thereby controlling the flow path of the heat exchange medium.

[0047] like Figure 1 , Figure 5 As shown ( Figure 5 (The bold black line in the middle represents the flow path of the heat exchange medium). In some embodiments, the flow path 115 is located outside the second chamber 114 and the lower end of the flow path 115 extends to communicate with the water flow path 1141. By setting the flow path 115 to be located outside the second chamber 114, the two flow paths are prevented from interfering with each other, making the flow path of the heat management system 100 clearer.

[0048] like Figure 2As shown, in some embodiments, the outlet end of the flow path 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. The valve core 12 rotates to make the second switching channel 122 simultaneously connected with the flow path 115 and the water flow channel 1141, or to make the second switching channel 122 disconnected from at least one of the flow path 115 and the water flow channel 1141, thereby further increasing the flow path and increasing the selection. When the valve core 12 rotates, the second switching channel 122 is simultaneously connected to the flow path channel 115 and the water flow channel 1141. This allows the liquid in the water tank 20 to enter the second switching channel 122 through the flow path channel 115. The second switching channel 122 guides the liquid to the water flow channel 1141, which is connected to the first chamber. The first chamber is connected to the first connecting valve port 111, and finally, the liquid in the water tank 20 flows out from the first connecting valve port 111. When the valve core 12 rotates, the second switching channel 122 is disconnected from at least one of the flow path channel 115 and the water flow channel 1141, thus breaking the flow path and stopping the liquid in the water tank 20 from flowing out from the first connecting valve port 111.

[0049] The water tank 20 is provided with an inlet for injecting liquid into the water tank 20. An external pipeline is connected to the inlet for liquid supply. The liquid supplied by the external pipeline can flow out from the first connecting valve port 111, forming a complete flow path.

[0050] like Figure 1 , Figure 5 As shown, in some embodiments, the flow path 115 extends to the top wall of the housing 11, the water tank 20 is supported on the housing 11, and the outlet is inserted into the flow path 115. That is, the water tank 20 is positioned above the housing 11, so that the heat exchange medium in the water tank 20 can enter the flow path 115 under its own gravity, automatically replenishing the heat exchange medium.

[0051] like Figure 1 , Figure 3 As shown, in some embodiments, multiple second connection valve ports 112 are located on the same side of the housing 11. By arranging multiple second connection valve ports 112 on the same side of the housing 11, it is convenient to connect multiple second valve ports to external pipelines, thereby improving efficiency. It can be understood that with multiple second connection valve ports 112 located on the same side of the housing 11, when installing external pipelines onto the second connection valve ports 112, installation can be performed by facing only one side of the housing 11, without needing to change the orientation of the multi-channel switching valve 10. For example, if three second connection valve ports 112 are located on the front side, when installing external pipelines onto the second connection valve ports 112, the installer only needs to face the front side of the multi-channel switching valve 10.

[0052] In some embodiments, multiple second connection ports 112 are located on different sides of the housing 11, providing users with more options, eliminating the need for twisting external pipelines, and making the routing of external pipelines clearer.

[0053] like Figure 1 As shown, optionally, the first connecting valve port 111 and the second connecting valve port 112 are located on opposite sides of the housing 11. By setting the first connecting valve port 111 and the second connecting valve port 112 to opposite sides of the housing 11, the probability of installation errors is reduced. Both the first connecting valve port 111 and the second connecting valve port 112 need to be connected to external pipelines, but the functions of the first connecting valve port 111 and the second connecting valve port 112 are different. If the external pipeline that should be installed on the first connecting valve port 111 is installed on the second connecting valve port 112, it will inevitably cause damage. This invention separates the first connecting valve port 111 and the second connecting valve port 112 on opposite sides, avoiding the problem of misinstallation when the first connecting valve port 111 and the second connecting valve port 112 are installed on the same side, thus improving safety.

[0054] For example, the second connecting valve port 112 is located on the front side of the housing 11, and the first connecting valve port 111 is located on the rear side of the housing 11. When installing the external pipeline onto the second connecting valve port 112, first face the front side and then face the rear side to install the first connecting valve port 111. The installer can easily distinguish the first connecting valve port 111 and the second connecting valve port 112 by the front and rear direction.

[0055] In some embodiments, the first connecting valve port 111 and the second connecting valve port 112 are located on the same side of the housing 11. This arrangement facilitates installation. Both the first connecting valve port 111 and the second connecting valve port 112 require connection to external pipelines. When installing external pipelines onto the first connecting valve port 111 and the second connecting valve port 112, their shared location on the same side allows the installer to complete the installation without changing their orientation. However, it is understood that the location of the first connecting valve port 111 and the second connecting valve port 112 is not limited to the above-described configuration and can be determined based on specific circumstances.

[0056] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the thermal management system 100 further includes a control module 40, which is fixed to the housing 11 and connected to the valve core 12 to drive the valve core 12 to rotate. By fixing the control module 40 to the housing 11, the integration is further improved.

[0057] Specifically, the housing 11 includes a body and a cover plate. The valve core 12 is located inside the body, and the cover plate covers the body. The control module 40 can be located on either the body or the cover plate. For example, the control module 40 can be located on the body to increase stability; or the control module 40 can be located on the cover plate for easier installation.

[0058] like Figure 1 , Figure 3 and Figure 4 As shown, optionally, the control module 40 and the water tank 20 are distributed on opposite sides of the housing 11. By distributing the control module 40 and the water tank 20 on opposite sides of the housing 11, the components are more dispersed on the housing 11, reducing the inconvenience of wiring connections caused by the concentration of components. At the same time, the center of gravity is on the housing 11, making the thermal management system 100 stable.

[0059] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the thermal management system 100 further includes a heat exchanger 50, which is fixed to the housing 11 and / or the water tank 20. By setting the heat exchanger 50, heat exchange space is provided for other devices, facilitating cooperation with other components. For example, fixing the heat exchanger 50 to the housing 11 allows for more flexible integration; or, fixing the heat exchanger 50 to the water tank 20 allows for a larger volume of the water tank, making the installation of the heat exchanger more convenient.

[0060] In some embodiments, the housing 11 is provided with a mounting portion adapted to be fixed to the vehicle body. By providing the mounting portion, the difficulty of installing the housing 11 onto the vehicle body is reduced, and production efficiency is improved.

[0061] like Figure 1 As shown, specifically, at least one first switching channel 121 includes an inner flow channel 1211 and two connecting ports 1212. The inner flow channel 1211 is located inside the valve core 12, and the two connecting ports 1212 are located on the outer peripheral wall of the valve core 12. The two ends of the inner flow channel 1211 are respectively connected to the two connecting ports 1212. By setting the inner flow channel 1211, the space occupied by the valve core 12 is fully utilized, and the switching connection mode of multiple first connecting valve ports 111 and multiple second connecting valve ports 112 is increased, thereby increasing the adaptability to different vehicles 1000.

[0062] In some embodiments, at least one first switching channel 121 includes an outer flow channel that extends along the outer peripheral wall of the valve core 12. The outer flow channel is used to connect the water flow channel 1141 with one of the second connecting valve ports 112. Based on the inner flow channel 1211 set inside the valve core 12, the number of selectable modes is further increased, thereby meeting more operational needs.

[0063] The inner flow channel 1211 is located inside the valve core 12 to allow the second connecting valve port 112 to communicate with the water flow channel 1141 under complex conditions. For example, multiple second connecting valve ports 112 and multiple water flow channels 1141 are combined to form sixteen openings arranged in a 4x4 pattern. If the second connecting valve ports 112 on the diagonal are directly connected to the water flow channel 1141 through the outer flow channel on the outer peripheral wall of the valve core 12, it will inevitably affect the communication between the second connecting valve ports 112 on both sides of the diagonal and the water flow channel 1141. By placing 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.

[0064] In some embodiments, the water tank 20 is automatically replenished when the heat exchange medium changes, thereby preventing changes in the state of the heat exchange medium. The specific principle can be found in pet water replenishment devices, which will not be elaborated here.

[0065] In some embodiments, an automatic water replenishment valve is provided between the water tank 20 and the multi-channel switching valve 10.

[0066] Specifically, the automatic water replenishment valve includes a valve body, inlet and outlet chambers located within the valve body, a valve control chamber connected to the inlet and outlet chambers, a valve stem located within the valve control chamber, a main valve disc mounted on the valve stem and tightly fitted with the valve seat, the valve control chamber being divided into front and rear chambers by a diaphragm, the valve stem being mounted in the central hole of the diaphragm and fixed to the diaphragm by the main valve disc and fasteners, and a booster spring being mounted on the valve stem located at the rear section of the diaphragm; an inlet and outlet pipe are respectively provided on the cavity walls of the rear chamber of the valve control chamber and the inlet chamber of the valve body, and the inlet and outlet pipes are connected to a reversing valve through connecting pipes; the operating device of the reversing valve is a linkage mechanism with a float at its lower end. The linkage mechanism includes a lifting rod with a float at its end, a control rod, and a counterweight pendulum hinged to the support base plate. One end of the control rod is connected to a directional valve mounted on the support base plate, and the other end is hinged to the middle section of the lifting rod. One end of the counterweight pendulum is connected to the upper end of the lifting rod via a hinge pin, and the other end is fitted with a counterweight. To achieve smooth, shock-free, and vibration-free opening and closing of the main valve disc, an auxiliary valve disc with a diameter matching the valve seat orifice diameter is installed on the valve stem in front of the main valve disc to provide damping.

[0067] The following is combined with Figures 1 to 5 This describes a specific embodiment of the thermal management system 100 of the present invention.

[0068] A thermal management system 100 includes: a multi-channel switching valve 10, a water tank 20, a water pump 30, a control module 40, and a heat exchanger 50.

[0069] The multi-channel switching valve 10 includes a housing 11 and a valve core 12.

[0070] The housing 11 is provided with two first connecting valve ports 111 and three second connecting valve ports 112. The housing 11 contains two first chambers, one second chamber 114, and two flow channels 115. The second chamber 114 has two water flow channels 1141 communicating with the two first chambers, with each water flow channel 1141 corresponding to one of the two first chambers. The two first connecting valve ports 111 are also corresponding to and communicating with the two first chambers. The three second connecting valve ports 112 are communicating with the second chamber 114, and the two flow channels 115 are corresponding to and communicating with the two first chambers. The flow channels 115 are located outside the second chamber 114, and their lower ends extend to communicate with the water flow channels 1141. The flow channels 115 extend to the top wall of the housing 11. The three second connecting valve ports 112 are located on the front side of the housing 11, and the two first connecting valve ports 111 are located on the rear side of the housing 11.

[0071] The valve core 12 is rotatably disposed within the second chamber 114. The valve core 12 has an inner flow channel 1211, two connecting ports 1212, and an outer flow channel. The inner flow channel 1211 is located inside the valve core 12, and the two connecting ports 1212 are located on the outer peripheral wall of the valve core 12. The two ends of the inner flow channel 1211 are respectively connected to the two connecting ports 1212. The two connecting ports 1212 are adapted to connect the water flow channel 1141 and one of the second connecting valve ports 112. Rotation of the valve core 12 causes the water flow channel 1141 to switch between being connected to at least two of the second connecting valve ports 112. The outer flow channel extends along the outer peripheral wall of the valve core 12 and begins to connect the water flow channel 1141 and one of the second connecting valve ports 112. Rotation of the valve core 12 causes the water flow channel 1141 to switch between being connected to at least two of the second connecting valve ports 112.
