[0058] In this embodiment, the multi-way valve integrated module 100 at least comprises a base 10, a multi-way valve 30 and at least one pump 20. The multi-way valve 30 and the pump 20 are both mounted on the base 10, and a plurality of liquid passages D are formed in the base 10, and the liquid passages D allow liquid media to flow through.

[0116] The eighth liquid passage D8 is a two-pass liquid passage, one of which is occupied by valve port No. 8 of the multi-way valve 30 , and the first quick-connect connector 41 at the other liquid passage is connected to the liquid outlet of the heater 720 .

[0117] In some optional embodiments, the motor heat exchange pipeline 500 includes a motor pipeline branch 510 and a radiator pipeline branch 520 .

[0118] The motor pipeline branch 510 is provided with a motor 511, and the radiator pipeline branch 520 is provided with a radiator 521. The liquid inlet of the motor 511 is connected to the liquid outlet of the motor loop pump 21, and the liquid outlet of the radiator 521 is connected to the multi-way valve 30 via the fifth liquid passage D5.

[0119] The liquid outlet of the motor 511 and the liquid inlet of the radiator 521 are connected to the multi-way valve 30 via the fourth liquid passage D4.

[0121] By controlling the on-off of the motor pipeline branch 510 and the radiator pipeline branch 520 , the heat dissipation of the motor 511 can be achieved through the radiator 521 .

[0122] Specifically, the motor heat exchange pipeline 500 is connected to valve ports No. 3, No. 4 and No. 5 of the multi-way valve 30, that is, the third liquid passage D3, the fourth liquid passage D4 and the fifth liquid passage D5 occupy valve ports No. 3, No. 4 and No. 5 of the multi-way valve 30 respectively.

[0123] Furthermore, the motor pipeline branch 510 is also provided with a motor pipeline liquid storage tank 514 , and the third liquid passage D3 is connected to the liquid replenishing port of the motor pipeline liquid storage tank 514 .

[0124] Specifically, the third liquid passage D3 is a three-way liquid passage, one of the liquid passage holes is occupied by valve port No. 3 of the multi-way valve 30, another liquid passage hole is connected to the liquid inlet of the motor 511 via the fourth quick-plug connector 44 at the liquid outlet of the motor loop pump 21, and the third quick-plug connector 43 at the last liquid passage hole is connected to the liquid replenishing port of the motor pipeline storage tank 514.

[0132] Figure 6 This is a schematic diagram of the battery cooling module. Figure 6 In some optional embodiments, the multi-way valve 30 is configured to connect the first liquid passage D1 with the second liquid passage D2 and the sixth liquid passage D6 with the ninth liquid passage D9, so that the battery heat exchange pipeline 600 cooperates with the multi-way valve integrated module 100 to form a circuit for cooling the battery 610.

[0133] In this embodiment, the first liquid passage D1 is connected to the second liquid passage D2, that is, the valve port No. 1 and the valve port No. 2 of the multi-way valve 30 are connected, and the sixth liquid passage D6 is connected to the ninth liquid passage D9, that is, the valve port No. 6 and the valve port No. 9 of the multi-way valve 30 are connected. In this way, the battery heat exchange pipeline 600 cooperates with the multi-way valve integrated module 100 to form a battery cooling circuit, and specifically cools the battery 610 through the heat exchanger 620.

[0134] Figure 7 is a diagram of the warm air mode. Figure 7 In some optional embodiments, the multi-way valve 30 is configured to connect the seventh liquid passage D7 with the eighth liquid passage D8, so that the warm air pipeline 700 cooperates with the multi-way valve integrated module 100 to form a warm air circuit.

[0135] In this embodiment, the seventh liquid passage D7 is connected to the eighth liquid passage D8, that is, the valve port No. 7 is connected to the valve port No. 8 of the multi-way valve 30. In this way, the warm air pipeline 700 cooperates with the multi-way valve integrated module 100 to form a warm air loop.

[0136] Figure 8 is a schematic diagram of the motor cooling mode. Figure 8In some optional embodiments, the multi-way valve 30 is configured to connect the third liquid passage D3 with the fifth liquid passage D5, so that the motor heat exchange pipeline 500 cooperates with the multi-way valve integrated module 100 to form a circuit for dissipating heat to the motor 511.

[0137] In this embodiment, the third liquid passage D3 is connected to the fifth liquid passage D5, that is, the valve port No. 3 and the valve port No. 5 of the multi-way valve are connected. In this way, the motor heat exchange pipeline 500 cooperates with the multi-way valve integrated module 100 to form a motor cooling circuit, specifically, the heat dissipation of the motor 511 is performed through the radiator 521.

[0138] Combining the above, we can see that Figure 6 The battery cooling mode shown is mainly for application scenarios where the battery 610 is cooled only by the heat exchanger 620, the motor 511 does not need to be cooled, and the passenger compartment heater is not turned on. Figure 7 The heating mode shown is mainly for application scenarios where the passenger compartment heating is turned on, the motor 511 does not need to be cooled, and the battery 610 does not need to be cooled. Figure 8 The motor cooling mode shown is mainly for application scenarios where the motor 511 needs to be cooled, the battery 610 does not need to be cooled, and the heater does not need to be turned on.

[0139] It should be noted that the battery cooling circuit, the heating circuit and the motor cooling circuit are the basic circuits of the vehicle thermal management system. The battery circuit pump 22 in the battery cooling circuit, the heating circuit pump 23 in the heating circuit and the motor circuit pump 21 in the motor cooling circuit provide power for the heat exchange medium in each circuit and are all integrated on the base 10.

[0140] For example, for application scenarios where the battery 610 does not need to be cooled, the motor 511 does not need to be cooled, and the heater does not need to be turned on, the battery circuit pump 22, the heater circuit pump 23, and the motor circuit pump 21 can be turned off, that is, the heat exchange medium does not flow. The above application scenarios can also be achieved by switching the corresponding liquid passages to the isolation state.

[0141] For the application scenario where the motor 511 needs to be cooled, the battery 610 needs to be cooled, and the passenger compartment heater is turned on, the first liquid passage D1 is connected to the second liquid passage D2, the sixth liquid passage D6 is connected to the ninth liquid passage D9, the third liquid passage D3 is connected to the fifth liquid passage D5, and the seventh liquid passage D7 is connected to the eighth liquid passage D8, that is, Figure 6 The battery cooling module shown, Figure 7 Warm air mode as shown and Figure 8 The motor cooling mode shown is a combination of all three.

[0142] For the application scenario where the battery 610 needs to be cooled, the motor 511 needs to be cooled, and the passenger compartment heater does not need to be turned on, the first liquid passage D1 is connected to the second liquid passage D2, the sixth liquid passage D6 is connected to the ninth liquid passage D9, the third liquid passage D3 is connected to the fifth liquid passage D5, and the seventh liquid passage D7 is isolated from the eighth liquid passage D8, that is, Figure 6 The battery cooling module shown is Figure 8 The motor cooling mode shown is a combination of the two.

[0143] For the application scenario where the battery 610 does not need to be cooled, the motor 511 needs to be cooled, and the passenger compartment heater is turned on, the first liquid passage D1 is isolated from the second liquid passage D2, the sixth liquid passage D6 is isolated from the ninth liquid passage D9, the third liquid passage D3 is connected to the fifth liquid passage D5, and the seventh liquid passage D7 is connected to the eighth liquid passage D8, that is, Figure 7 The warm air mode shown is Figure 8 The motor cooling mode shown is a combination of the two.

[0144] For the application scenario where the battery 610 needs to be cooled, the motor 511 does not need to be cooled, and the passenger compartment heater is turned on, the first liquid passage D1 is connected to the second liquid passage D2, the sixth liquid passage D6 is connected to the ninth liquid passage D9, the third liquid passage D3 is isolated from the fifth liquid passage D5, and the seventh liquid passage D7 is connected to the eighth liquid passage D8, that is, Figure 6 The battery cooling module shown is Figure 7 The warm air mode shown is a combination of the two.

[0145] It should be understood that since the valve ports occupied by the three circuits do not interfere with each other, at least one of the warm air mode, the motor cooling mode and the battery cooling module can be performed.

[0146] Fig. 9 is a schematic diagram of the battery heating mode. Fig. 9 In some optional embodiments, the multi-way valve 30 is configured to connect the first liquid passage D1 with the second liquid passage D2, the sixth liquid passage D6 with the seventh liquid passage D7, and the eighth liquid passage D8 with the ninth liquid passage D9, so that the battery heat exchange pipeline 600 and the warm air pipeline 700 cooperate with the multi-way valve integrated module 100 to form a circuit for heating the battery 610.

[0147] In this embodiment, the first liquid passage D1 is connected with the second liquid passage D2, the sixth liquid passage D6 is connected with the seventh liquid passage D7, and the eighth liquid passage D8 is connected with the ninth liquid passage D9, that is, the valve port No. 1 of the multi-way valve 30 is connected with the valve port No. 2, the valve port No. 6 is connected with the valve port No. 7, and the valve port No. 8 is connected with the valve port No. 9.

[0148] This mode is mainly applicable to the situation where the temperature of the battery 610 is relatively low. The battery heat exchange pipeline 600 is connected to the warm air pipeline 700 through the multi-way valve integrated module 100. In this way, the heater 710 can heat the heat exchange medium in the pipe heat, and the heated heat exchange medium can flow through the battery 610 to heat the battery 610, so that the battery 610 is at a suitable operating temperature.

[0149] It should be understood that, based on the battery heating mode, if there is an application scenario where the motor 511 needs to be cooled, the third liquid passage D3 is connected to the fifth liquid passage D5, that is, Fig. 9 The battery heating mode shown is the same as Figure 8 The motor cooling mode shown is a combination of the two.

[0150] Fig.10 Schematic diagram of battery radiator cooling mode. Fig.10 In some optional embodiments, the multi-way valve 30 is configured to connect the third liquid channel D3 with the first liquid channel D1, the second liquid channel D2 with the fifth liquid channel D5, and the sixth liquid channel D6 with the ninth liquid channel D9, so that the motor heat exchange pipeline 500 and the battery heat exchange pipeline 600 cooperate with the multi-way valve integrated module 100 to form a circuit for dissipating heat to the battery 610.

[0151] In this embodiment, the third liquid passage D3 is connected to the first liquid passage D1, the second liquid passage D2 is connected to the fifth liquid passage D5, and the sixth liquid passage D6 is connected to the ninth liquid passage D9, that is, the valve port No. 3 of the multi-way valve 30 is connected to the valve port No. 1, the valve port No. 2 is connected to the valve port No. 5, and the valve port No. 6 is connected to the valve port No. 9.

[0152] In this way, the motor heat exchange pipeline 500 and the battery heat exchange pipeline 600 are connected through the multi-way valve integrated module 100, and the battery 610 can not only be cooled by the heat exchanger 620, but also dissipate heat through the radiator 521, so that the battery 610 can be quickly cooled to a suitable operating temperature.

[0153] It should be understood that, based on the battery radiator cooling mode, if there is an application scenario where the passenger compartment needs to open the heating, the seventh liquid passage D7 is connected to the eighth liquid passage D8, that is, Fig.10 The battery radiator cooling mode shown is similar to Figure 7 The warm air mode shown is a combination of the two.

[0154] Fig.11 This is a schematic diagram of the motor waste heat recovery mode. Fig.11In some optional embodiments, the multi-way valve 30 is configured to connect the third liquid passage D3 with the first liquid passage D1, the second liquid passage D2 with the fourth liquid passage D4, and the sixth liquid passage D6 with the ninth liquid passage D9, so that the motor heat exchange pipeline 500 and the battery heat exchange pipeline 600 cooperate with the multi-way valve integrated module 100 to form a loop for transferring the waste heat of the motor 511 to the battery 610.

[0155] In this embodiment, the third liquid passage D3 is connected to the first liquid passage D1, the second liquid passage D2 is connected to the fourth liquid passage D4, and the sixth liquid passage D6 is connected to the ninth liquid passage D9, that is, the valve port No. 3 of the multi-way valve 30 is connected to the valve port No. 1, the valve port No. 2 is connected to the valve port No. 4, and the valve port No. 6 is connected to the valve port No. 9.

[0156] In this way, the motor pipeline branch 510 in the motor heat exchange pipeline 500 is connected to the battery heat exchange pipeline 600. The heat generated by the motor 511 is absorbed by the heat exchange medium and can flow through the battery 610 to heat the battery. In this way, there is no need to heat the battery 610 through the warm air pipeline 700, thereby reducing energy consumption.

[0157] It should be understood that on the basis of the motor waste heat recovery mode, if there is an application scenario where the passenger compartment needs to turn on the heater, the seventh liquid passage D7 is connected to the eighth liquid passage D8, that is, Fig.11 The waste heat recovery mode shown is similar to Figure 7 The warm air mode shown is a combination of the two.

[0158] Regardless of whether the battery 610 is heated by the waste heat of the heater 710 or the motor 511 , the air conditioning pipe system (not shown) connected to the heat exchanger 620 is not in operation, so the heat obtained by the battery 610 will not be lost through the heat exchanger 620 .

[0159] It should be noted that in Fig.10 and Fig.11 In the illustrated embodiment, the on / off status of valve ports No. 7 and No. 8 does not affect the corresponding modes, and thus, the warm air mode can be performed at the same time.

[0160] Fig.12 is a schematic diagram of the filling mode. Fig.12 In some optional embodiments, the multi-way valve 30 is configured to connect the second liquid passage D2 with the fifth liquid passage D5, the sixth liquid passage D6 with the seventh liquid passage D7, the eighth liquid passage D8 with the ninth liquid passage D9, and the first liquid passage D1 with the third liquid passage D3 or the fourth liquid passage D4, so that the motor heat exchange pipeline 500, the battery heat exchange pipeline 600, and the warm air pipeline 700 cooperate with the multi-way valve integrated module 100 to form a circuit for liquid injection.

[0161] In this embodiment, the second liquid passage D2 is connected with the fifth liquid passage D5, the sixth liquid passage D6 is connected with the seventh liquid passage D7, the eighth liquid passage D8 is connected with the ninth liquid passage D9, and the first liquid passage D1 is connected with the third liquid passage D3 or the fourth liquid passage D4, that is, the valve port No. 2 of the multi-way valve 30 is connected with the valve port No. 5, the valve port No. 6 is connected with the valve port No. 7, the valve port No. 8 is connected with the valve port No. 9, and the valve port No. 1 is connected with the valve port No. 3 or the valve port No. 4.

[0162] exist Fig.12 In the illustrated embodiment, valve port No. 1 is connected to valve port No. 3, so that the battery heat exchange pipeline 600, the warm air pipeline 700 and the motor heat exchange pipeline 500 are connected via the multi-way valve integration module 100, that is, the three are connected to form a loop for running the heat exchange medium through each pipeline, so that it is convenient for operators to inject the heat exchange medium into the vehicle thermal management system and ensure that the added heat exchange medium can flow through each pipeline.

[0163] It should be noted that the mode switching of the vehicle thermal management system can be controlled by the vehicle controller. In different modes, at least one of the motor circuit pump 21, the battery circuit pump 22 and the heater circuit pump 23 is controlled to be in an operating state to ensure that the heat exchange medium can flow normally.

[0164] In addition, the multi-way valve integrated module 100 is not limited to being used in a vehicle thermal management system, but can also be used in other devices equipped with a thermal management system.

[0165] 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.
