[0030] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of the thermal management system of the vehicle in this application. The thermal management system 100 includes a motor coolant pipeline 10, a battery coolant pipeline 20, and an air conditioner warm air pipeline 30.

[0031] The motor coolant pipeline 10 includes a plurality of first coolant flow loops 101, one of which is connected to the air conditioning heating pipeline; the air conditioning heating pipeline 30 includes a second coolant flow loop 301 and a heat transfer loop 302, and the heat transfer loop 302 is connected to the battery coolant pipeline 20; the thermal management system 100 also includes a first control valve 40, a second control valve 50 and a third control valve 60; the first control valve 40 includes a plurality of working modes, and when the first control valve 40 is in different working modes, different first coolant flow loops 101 in the plurality of first coolant flow loops 101 are connected; the second The control valve 50 includes a first predetermined working mode. When the second control valve 50 is in the first predetermined working mode, the battery coolant pipeline 20 is connected; the third control valve 60 includes a second predetermined working mode. When the third control valve 60 is in the second predetermined working mode, the second coolant flow circuit 301 and the heat transfer circuit 302 are both connected; wherein, the thermal management system 100 controls the second control valve 50 to be in the first predetermined working mode and the third control valve 60 to be in the second predetermined working mode in response to the exhaust instruction; and controls the first control valve 40 to switch between different working modes so that multiple first coolant flow circuits 201 are all connected.

[0032] Specifically, Figure 1 The thermal management system 100 shown further includes a first water pump 10A and a first expansion tank 10B. The first water pump 10A is disposed on the motor coolant pipeline 10, and the first expansion tank 10B is connected to the motor coolant pipeline 10. After controlling the first control valve 40 to switch to a target working mode of the plurality of working modes, the thermal management system 100 is also used to control the operation of the first water pump 10A so that the first water pump 10A pumps the liquid in the first expansion tank 10B into the first coolant flow loop 101 corresponding to the target working mode for circulation. In this way, after the first coolant flow loop 101 is turned on, the liquid in the first expansion tank 10B flows in the first coolant flow loop 101, ensuring that the gas in the first coolant flow loop 101 is discharged, thereby improving the reliability of the thermal management system 100.

[0033] More specifically, Figure 1The first control valve 40 shown is a five-way waterway reversing valve. The five-way waterway reversing valve 40 includes a first port 1, a second port 2, a third port 3, a fourth port 4, and a fifth port 5. Among them, the first port 1 and the third port 3 are connected, and after the second port 2 and the fourth port 4 are connected, a first target coolant flow circuit connecting to the air-conditioning warm air pipeline 30 is formed. The third port 3 and the fourth port 4 are connected, and the second port 2 and the fifth port 5 are connected to form a second target coolant flow circuit. The first target coolant flow circuit and the second target coolant flow circuit jointly cover all pipelines of the motor coolant pipeline 10. The thermal management system 100 controls the first control valve 40 to switch between different working modes, including: the thermal management system 100 controls the five-way waterway reversing valve 40 to be in the first target working mode, where the first port 1 and the third port 3 are connected, and the second port 2 and the fourth port 4 are connected. After the five-way waterway reversing valve 40 has been in the first target working mode for a first preset duration, the thermal management system 100 controls the five-way waterway reversing valve 40 to switch to the second target working mode, where the third port 3 and the fourth port 4 are connected, and the second port 2 and the fifth port 5 are connected. After the five-way waterway reversing valve 40 has been in the second target working mode for a second preset duration, the thermal management system 100 controls the five-way waterway reversing valve 40 to switch to the first working mode.

[0034] Please refer further to Figure 1 , the thermal management system 100 further includes a second water pump 20A and a second expansion tank 20B. The second water pump 20A is arranged on the battery coolant pipeline 20, and the second expansion tank 20B is connected to the battery coolant pipeline 20. After the thermal management system 100 controls the second control valve 50 to be in the first predetermined working mode, it is further used to control the operation of the second water pump 20A, so that the second water pump 20A pumps the liquid in the second expansion tank 20B into the battery coolant pipeline 20 for circulating flow. By this means, after the battery coolant pipeline 20 is conducted, the liquid in the second expansion tank 20B flows in the battery coolant pipeline 20, ensuring that the gas in the battery coolant pipeline 20 is discharged, thereby improving the reliability of the thermal management system 100.

[0035] Please refer further to Figure 1 , the thermal management system 100 further includes a third water pump 30A and a third expansion tank 30B. The third water pump 30A is arranged on the air-conditioning warm air pipeline 30, and the third expansion tank 30B is connected to the air-conditioning warm air pipeline 30. After the thermal management system 100 controls the third control valve 60 to be in the second predetermined working mode, it is further used to control the operation of the third water pump 30A, so that the third water pump 30A pumps the liquid in the third expansion tank 30B into the second coolant flow circuit 301 for circulating flow. By this means, after the second coolant flow circuit 301 is conducted, the liquid in the third expansion tank 30B flows in the second coolant flow circuit 301, ensuring that the gas in the second coolant flow circuit 301 is discharged, thereby improving the reliability of the thermal management system 100.

[0036] It should be noted that the third control valve 60 in this embodiment is a three-way valve, and the three-way valve 60 is used to control the on and off of the second coolant flow circuit 301 and the heat transfer circuit 302; the thermal management system 100 controls the third control valve 60 to be in the second predetermined working mode, including: controlling the three-way valve 60 to be in a preset opening degree so that both the second coolant flow circuit 301 and the heat transfer circuit 302 are on.

[0037] Furthermore, the first expansion tank 10B, the second expansion tank 20B, and the third expansion tank 30B in this embodiment all have multiple functions. Taking the first expansion tank 10B as an example, on the one hand, the first expansion tank 10B can provide the liquid circulating in the first coolant flow circuit 101. On the other hand, after the first water pump 10A operates, the gas in the first coolant flow circuit 101 is squeezed into the first expansion tank 10B, and the first expansion tank 10B can discharge the gas, thereby ensuring that the gas in the first expansion tank 10B will not re-enter the first coolant flow circuit 101, improving the reliability of the thermal management system 100. It can be understood that the functions of the second expansion tank 20B and the third expansion tank 30B are the same as those of the first expansion tank 10B, and for the sake of avoiding repetition, they will not be elaborated here.

[0038] For the sake of easy understanding, the following combines Figures 2 to 3 to specifically describe the exhaust process of the thermal management system 100 of the present application: 1. Please refer to Figure 2 , which is a schematic structural diagram of the thermal management system 100 when the first control valve of the present application is in the first target working mode, the second control valve is in the first predetermined working mode, and the third control valve is in the second predetermined working mode.

[0039] After the thermal management system 100 receives the exhaust instruction, it controls the water path five-way directional valve 40 to switch to the first working mode. As Figure 2 shown, the first port 1 and the third port 3 of the water path five-way directional valve 40 are connected, and the second port 2 and the fourth port 4 are connected. It controls the first water pump 10A to operate at the first speed for the first preset duration; at the same time, the thermal management system 100 controls the second control valve 50 to be in Figure 2 the first predetermined working mode shown, controls the second water pump 20A to operate at the second speed for the third preset duration; at the same time, the thermal management system 100 controls the third control valve 60 to be in a preset opening degree, and controls the third water pump 30A to operate at the third speed for the fourth preset duration.

[0040] It is understandable that in this embodiment, no specific limitations are imposed on the first rotational speed, the first preset duration, the second rotational speed, the third preset duration, the third rotational speed, and the fourth preset duration, and they can be set according to actual requirements. It is only necessary to ensure that after the first water pump 10A, the second water pump 20A, and the third water pump 30A operate, the gas in the currently conducting pipeline can be emptied.

[0041] 2. Please refer to Figure 3 , which is a schematic structural diagram of the thermal management system 100 when the first control valve of this application is in the second target working mode, the second control valve is in the first predetermined working mode, and the third control valve is in the second predetermined working mode.

[0042] After the first water pump 10A operates at the first rotational speed for the first preset duration, the thermal management system 100 controls the five-way water path changeover valve 40 to switch to the second target working mode. As Figure 3 shown, the third port 3 is connected to the fourth port 4, and the second port 2 is connected to the fifth port 5. Control the first water pump 10A to operate at the fourth rotational speed for the second preset duration.

[0043] It is worth noting that due to the coordinated cooperation of the control valves in the motor coolant pipeline 10 and the battery coolant pipeline 20, in order to ensure the normal operation of the thermal management system 100, the sum of the first preset duration and the second preset duration in this embodiment is equal to the third preset duration, that is, the operating times of the first water pump 10A and the second water pump 20A are the same.

[0044] It is understandable that in this embodiment, no specific limitations are imposed on the magnitudes of the fourth rotational speed and the second preset duration, and they can be set according to actual requirements.

[0045] 3. After the first water pump 10A operates at the fourth rotational speed for the second preset duration, the thermal management system 100 controls the five-way water path changeover valve 40 to switch to the first target working mode, and the thermal management system 100 enters the standby state.

[0046] Compared with the related art, the embodiments of the present application have at least the following advantages: Since the motor coolant pipeline includes a plurality of first coolant flow circuits, by setting the first control valve, when the first control valve is in different working modes, different first coolant flow circuits in the plurality of first coolant flow circuits are conducted. Therefore, the thermal management system makes each first coolant flow circuit be conducted by switching the working mode of the first control valve. That is to say, after the thermal management system pumps the liquid into the first coolant flow circuit corresponding to the current working mode through the water pump and the gas in the first coolant flow circuit corresponding to the current working mode is discharged, the thermal management system switches the working mode of the first control valve, so that the water pump pumps the liquid into the first coolant flow circuit that was not conducted before, thereby realizing the rapid discharge of the gas in all the first coolant flow circuits, reducing the exhaust time of the thermal management system, and improving the exhaust efficiency of the thermal management system; In addition, the thermal management system also controls the conduction of the battery coolant pipeline and the air-conditioning warm air pipeline by setting the second control valve and the third control valve respectively, ensuring that the gas in the battery coolant pipeline and the air-conditioning warm air pipeline can be discharged, so as to ensure that the gas in the pipelines of the entire thermal management system is discharged, enabling more coolant to be replenished at one time and improving the user experience.

[0047] Please refer to Figure 4 , Figure 4 is a step flowchart of an embodiment of the exhaust method of the thermal management system of the vehicle of the present application. According to different requirements, the order of the steps in this flowchart can be changed, and some steps can be omitted. The exhaust method of the thermal management system of the vehicle of the present application can be applied to the thermal management system 100 of the foregoing embodiment, but is not limited thereto. The embodiments of the present application do not limit this.

[0048] The specific process of this embodiment is as Figure 4 shown, including the following steps: Step 101, in response to the exhaust instruction, control the second control valve to be in the first predetermined working mode and the third control valve to be in the second predetermined working mode.

[0049] In some embodiments, the generation method of the exhaust instruction includes one or any combination of the following: in response to a touch operation on a virtual button, generate an exhaust instruction; in response to a touch operation on a physical button, generate an exhaust instruction; wherein, the virtual button is displayed on the center control display screen of the vehicle, and the physical button is provided on the vehicle.

[0050] It can be understood that the present embodiment does not specifically limit the generation method of the exhaust instruction, which can be set according to actual needs.

[0051] In some embodiments, the exhaust command can be repeatedly responded. That is, after the first exhaust cycle of the thermal management system ends, the exhaust cycle of the thermal management system can be triggered again by the exhaust command.

[0052] Step 102: Control the first control valve to switch between different working modes so that the plurality of first coolant flow circuits are all connected.

[0053] How to switch between different working modes has been described in detail in the above embodiments, and will not be described again here to avoid repetition.

[0054] Compared with the related art, the embodiments of the present application have at least the following advantages: since the motor coolant pipeline includes multiple first coolant flow circuits, by setting a first control valve, when the first control valve is in different working modes, different first coolant flow circuits among the multiple first coolant flow circuits are connected. Therefore, the thermal management system switches the working mode of the first control valve so that each first coolant flow circuit will be connected. That is to say, after the thermal management system pumps liquid into the first coolant flow circuit corresponding to the current working mode through the water pump, and after the gas in the first coolant flow circuit corresponding to the current working mode is discharged, the thermal management system switches the working mode of the first control valve so that the water pump pumps liquid into the first coolant flow circuit that was not previously opened, thereby achieving rapid discharge of gas from all first coolant flow circuits, reducing the exhaust time of the thermal management system and improving the exhaust efficiency of the thermal management system; in addition, the thermal management system also controls the conduction of the battery coolant pipeline and the air-conditioning heater pipeline respectively by setting the second control valve and the third control valve to ensure that the gas in the battery coolant pipeline and the air-conditioning heater pipeline can be discharged, thereby ensuring that the gas in the pipelines in the entire thermal management system is discharged, so that more coolant can be replenished at one time, thereby improving the user experience.
