[0057] In addition, the present application is not only understood by the actual terms used, but also by the meaning implied by each term.

[0058] The technical scheme provided by each embodiment of the present application will be described in detail below in connection with the drawings.

[0059] The present application provides a kind of thermal management system, which is applied to vehicle. Reference Figure 1 The thermal management system 1 provided by the embodiments of the present application includes: condenser 10, first multi-way valve 20, radiator 30, battery module 40 and air conditioner 50.

[0060] It should be noted that, exemplarily, the condenser 10 can be a water-cooled condenser (also known as a water-cooled condenser). The condenser 10 can use cooling liquid to absorb the heat released during the liquefaction of refrigerant. In other words, the cooling liquid input into the condenser 10 can absorb the heat released during the liquefaction of refrigerant, so that the cooling liquid carries heat and is output from the condenser 10.

[0061] In combination Figure 2 Exemplarily, the first multi-way valve 20 is a four-way valve. The first multi-way valve 20 is provided with one inlet and three outlets. Thus, the communication relationship of each outlet and inlet can be adjusted according to the demand, so that the cooling liquid input through the inlet can be supplied to the corresponding device according to the demand.

[0062] Exemplarily, the radiator 30 can be a low-temperature radiator. For example, the temperature range of a low-temperature radiator of a vehicle is generally from negative 40 degrees Celsius to positive 60 degrees Celsius.

[0063] Exemplarily, the air conditioner 50 can be a heating ventilation and air conditioning (HVAC). The air conditioner 50 is used to adjust the temperature in the passenger compartment.

[0064] It should be further noted that, since the condenser 10, the first multi-way valve 20, the radiator 30 and the air conditioner 50 can be directly purchased from the corresponding suppliers, the specific structure and working principle of the condenser 10, the first multi-way valve 20, the radiator 30 and the air conditioner 50 are not described here. In addition, although it is only listed here that the condenser 10 can be a water-cooled condenser, the radiator 30 can be a low-temperature radiator, and the air conditioner 50 can be a heating ventilation and air conditioning (HVAC), it can be understood that those skilled in the art can flexibly select appropriate types of condensers, radiators and air conditioners according to actual needs in the process of implementing the scheme provided in the embodiments of the present application, which will not be listed one by one here.

[0065] Further, in the embodiments of the present application, the cooling liquid outlet 11 of the condenser 10 is connected with the inlet 21 of the first multi-way valve 20. The first outlet 22 of the first multi-way valve 20 is connected with the cooling liquid inlet 12 of the condenser 10 through the radiator 30. The second outlet 23 of the first multi-way valve 20 is connected with the cooling liquid inlet 12 of the condenser 10 through the battery module 40. The third outlet 24 of the first multi-way valve 20 is connected with the cooling liquid inlet 12 of the condenser 10 through the air conditioner 50.

[0066] In this way, in the embodiments of the present application, the cooling liquid carrying heat output by the cooling liquid outlet 11 of the condenser 10 can be supplied to the battery module 40 and the air conditioner 50 according to the requirements by using the first multi-way valve 20, so as to facilitate providing heat energy to the battery module 40 and the air conditioner 50 according to the requirements. Moreover, by using the scheme in the embodiments of the present application, the heat of the air conditioner condenser can be fully utilized to heat the passenger compartment or the battery. Thus, the utilization rate of heat is improved, and the effects of reducing the energy consumption of the battery and improving the cruising range of the vehicle can be achieved.

[0067] Reference Figures 1 to 3 In some embodiments, the thermal management system 1 further comprises a second multi-way valve 60 and a second water pump 100.

[0068] In combination Figure 3 Exemplarily, the second multi-way valve 60 is a ten-way valve, and the second multi-way valve 60 has 10 valve ports. Each valve port can adjust its communication state according to the requirements. Since the second multi-way valve 60 can be directly purchased from the corresponding suppliers, the specific structure and working principle of the second multi-way valve 60 are not described here.

[0069] The second outlet 23 of the first multi-way valve 20 is connected with the seventh valve port 67 of the second multi-way valve 60 via the second water pump 100 and the battery module 40. The fifth valve port 65 of the second multi-way valve 60 is connected with the cooling liquid inlet 12 of the condenser 10.

[0070] With reference to Figure 8 In the case that the seventh valve port 67 of the second multi-way valve 60 is communicated with the fifth valve port 65 of the second multi-way valve 60, the second outlet 23 of the first multi-way valve 20 is connected with the cooling liquid inlet 12 of the condenser 10 via the battery module 40.

[0071] In this way, in the case that the battery module 40 needs to be heated, the seventh valve port 67 of the second multi-way valve 60 can be communicated with the fifth valve port 65 of the second multi-way valve 60. Thus, the circulating loop of the cooling liquid is: condenser 10→heater 130→first multi-way valve 20→second water pump 100→battery module 40→second multi-way valve 60→third water pump 140→condenser 10. Therefore, the battery module 40 can be heated by the cooling liquid carrying heat output by the cooling liquid outlet 11 of the condenser 10.

[0072] With reference to Figures 1 to 3 In some embodiments, the thermal management system 1 further comprises an electric drive module 70 and a first water pump 80.

[0073] Exemplarily, the electric drive module 70 can be a multi-in-one electric bridge. The multi-in-one electric bridge can be integrated with a motor, an automotive microcontroller unit (MCU), a power distribution unit (PDU), a direct current to direct current (DC / DC) converter and an on board charger (OBC) and the like. Of course, in other embodiments, the electric drive module 70 can also include a motor, an automotive microcontroller unit and a power distribution unit and the like which are arranged separately, which are not listed one by one here.

[0074] Further, the cooling liquid outlet 31 of the radiator 30 is connected with the fourth valve port 64 of the second multi-way valve 60. The second valve port 62 of the second multi-way valve 60 is connected with the first valve port 61 of the second multi-way valve 60 via the electric drive module 70 and the first water pump 80. The tenth valve port 610 of the second multi-way valve 60 is connected with the cooling liquid inlet 32 of the radiator 30.

[0075] In combination Figure 4In this way, when the fourth valve port 64 of the second multi-way valve 60 communicates with the second valve port 62 of the second multi-way valve 60, and the first valve port 61 of the second multi-way valve 60 communicates with the tenth valve port 610 of the second multi-way valve 60, the circulation loop of the cooling liquid is: radiator 30→second multi-way valve 60→first one-way valve 151→electric drive module 70→first water pump 80→second one-way valve 152→second multi-way valve 60→radiator 30. Thus, the electric drive module 70 can be cooled by the radiator 30 to prevent the electric drive module 70 from being damaged due to high temperature.

[0076] With reference to Figures 1 to 3 In some embodiments, the thermal management system 1 further comprises a chiller 90. The cooling liquid outlet 41 of the battery module 40 is connected with the seventh valve port 67 of the second multi-way valve 60. The ninth valve port 69 of the second multi-way valve 60 is connected with the cooling liquid inlet 91 of the chiller 90. The cooling liquid outlet 92 of the chiller 90 is connected with the eighth valve port 68 of the second multi-way valve 60. The third valve port 63 of the second multi-way valve 60 is connected with the cooling liquid inlet 42 of the battery module 40 through the second water pump 100.

[0077] In combination Figure 4 In this way, when the temperature of the battery module 40 is high, the seventh valve port 67 of the second multi-way valve 60 can communicate with the ninth valve port 69 of the second multi-way valve 60, and the eighth valve port 68 of the second multi-way valve 60 can communicate with the third valve port 63 of the second multi-way valve 60. The circulation loop of the cooling liquid is: battery module 40→second multi-way valve 60→chiller 90→second multi-way valve 60→third one-way valve 153→second water pump 100→battery module 40. Thus, the battery module 40 can be actively cooled by the chiller 90.

[0078] With reference to Figures 1 to 3 In some embodiments, the sixth valve port 66 of the second multi-way valve 60 is connected with the cooling liquid inlet 32 of the radiator 30. The second valve port 62 of the second multi-way valve 60 is further connected with the battery module 40 through the second water pump 100.

[0079] In combination Figure 6 In this way, when the temperature of the battery module 40 is high, the seventh valve port 67 of the second multi-way valve 60 can communicate with the ninth valve port 69 of the second multi-way valve 60, and the eighth valve port 68 of the second multi-way valve 60 can communicate with the sixth valve port 66 of the second multi-way valve 60, and the fourth valve port 64 of the second multi-way valve 60 can communicate with the second valve port 62 of the second multi-way valve 60. Thus, the circulation loop of the cooling liquid is: battery module 40→second multi-way valve 60→chiller 90→second multi-way valve 60→radiator 30→second multi-way valve 60→third one-way valve 153→second water pump 100→battery module 40. Thus, the battery module 40 can be passively cooled by the radiator 30.

[0080] With reference to Figures 1 to 3 In some embodiments, the thermal management system 1 further comprises a shut-off valve 156. The first outlet 22 of the first multi-way valve 20 is connected to the coolant inlet 32 of the radiator 30, and the coolant outlet 31 of the radiator 30 is connected to the coolant inlet 12 of the condenser 10 via the shut-off valve 156. In this way, the first outlet 22 of the first multi-way valve 20 can be connected to the coolant inlet 12 of the condenser 10 via the radiator 30, and the second outlet 23 of the first multi-way valve 20 can be connected to the coolant inlet 12 of the condenser 10 via the battery module 40.

[0081] In addition, with reference to Figure 6 Or Figure 8 In some working conditions, the coolant output by the radiator 30 can be prevented from flowing back to the condenser 10 by switching the shut-off valve 156 to the closed state.

[0082] With reference to Figure 1 In some embodiments, the thermal management system 1 further comprises a gas-liquid separator 110 and a compressor 120. The refrigerant outlet 93 of the refrigeration machine 90 is connected to the refrigerant inlet 13 of the condenser 10 via the gas-liquid separator 110 and the compressor 120. The refrigerant outlet 14 of the condenser 10 is connected to the refrigerant inlet 94 of the refrigeration machine 90.

[0083] The gas-liquid separator 110 is used to separate gaseous refrigerant and liquid refrigerant. In this way, the gaseous refrigerant can be delivered to the compressor 120. Further, the compressor 120 compresses the gaseous refrigerant, which releases heat, and the heat released by the gaseous refrigerant can be absorbed by the coolant of the condenser 10, so that the coolant outlet 11 of the condenser 10 can output coolant carrying heat. In addition, after the coolant absorbs the heat of the coolant, the refrigerant delivered to the condenser 10 is liquefied, and the liquefied refrigerant is delivered to the refrigeration machine 90, thereby cooling the coolant input into the refrigeration machine 90.

[0084] With reference to Figure 1 And Figure 2 In some embodiments, the air conditioner 50 comprises a heating core 51 and an evaporator 52. The refrigerant outlet 14 of the condenser 10 is further connected to the inlet of the gas-liquid separator 110 via the evaporator 52. The third outlet 24 of the first multi-way valve 20 is connected to the coolant inlet 12 of the condenser 10 via the heating core 51.

[0085] In this way, in combination with Figure 2 And Figure 4In the case that the inlet 21 of the first multi-way valve 20 is communicated with the third outlet 24 of the first multi-way valve 20, the cooling liquid carrying heat output by the cooling liquid outlet 11 of the condenser 10 can be delivered to the heater core 51, so that hot air blowing to the passenger compartment can be generated by the way that the air blower 53 blows air to the heater core 51.

[0086] In addition, in the case that the passenger compartment needs to be cooled, the refrigerant output by the refrigerant outlet 14 of the condenser 10 can be delivered to the evaporator 52, so that cold air blowing to the passenger compartment can be generated by the way that the air blower 53 blows air to the evaporator 52.

[0087] Reference Figures 1 to 3 In some embodiments, the thermal management system 1 further comprises a heater 130 and a third water pump 140. Exemplarily, the heater 130 can be a Positive Temperature Coefficient (PTC) heater.

The fifth valve port 65 of the second multi-way valve 60 is connected with the cooling liquid inlet 12 of the condenser 10 through the third water pump 140.

[0089] In this way, the cooling liquid delivered by the cooling liquid outlet 11 of the condenser 10 can be assisted to be heated by the heater 130. In addition, the cooling liquid can be smoothly returned to the condenser 10 by the third water pump 140.

[0135] In the water source heat pump (absorbing the electric drive, low-temperature radiator heat) heating passenger cabin / battery scenario, in the water source heat pump process, the circulating loop of the coolant is: refrigerating machine 90→second multi-way valve 60→first one-way valve 151→electric drive module 70→first water pump 80→second one-way valve 152→second multi-way valve 60→radiator 30→second multi-way valve 60→refrigerating machine 90.

The shut-off valve 156 is in the open state or the closed state, which has no effect on the circulating loop.

[0139] In the water source heat pump (absorbing the electric drive heat) heating passenger cabin / battery scenario, in the water source heat pump process, the circulating loop of the coolant is: refrigerating machine 90→second multi-way valve 60→first one-way valve 151→electric drive module 70→first water pump 80→second one-way valve 152→second multi-way valve 60→refrigerating machine 90.

[0143] However, for example, some ten-way valves switch the communication state by means of rotation of an internal valve core. Therefore, in the case where the second multi-way valve 60 is switched to the ninth state by rotation of the valve core, the third valve port 63 of the second multi-way valve 60 and the fourth valve port 64 of the second multi-way valve 60 can be in communication. Therefore, Figure 9 The second multi-way valve 60 shown in FIG. 8 has the third valve port 63 and the fourth valve port 64 in communication.

[0144] With reference to Figure 10 In the case where the thermal management system 1 is in the seventh mode, the first multi-way valve 20 is in the second state, the second multi-way valve 60 is in the ninth state, and the shut-off valve 156 is in the closed state.

[0151] It should be noted that, with reference to Figure 11 In the case where the thermal management system 1 is in the eighth mode, whether the third valve port 63 of the second multi-way valve 60 and the fourth valve port 64 of the second multi-way valve 60 are in communication has no effect on the circulation loop of the cooling liquid, and thus the third valve port 63 of the second multi-way valve 60 and the fourth valve port 64 of the second multi-way valve 60 can not be in communication.

[0152] However, for example, some ten-way valves switch the communication state by rotating the internal valve core. Therefore, in the case where the second multi-way valve 60 is switched to the tenth state by rotating the valve core, the third valve port 63 of the second multi-way valve 60 and the fourth valve port 64 of the second multi-way valve 60 can be exactly in the communication state. Therefore, Figure 11 The second multi-way valve 60 shown in FIG. 6 has the third valve port 63 and the fourth valve port 64 in the communication state.

[0153] With reference to Figure 12 In the case where the thermal management system 1 is in the ninth mode, the first multi-way valve 20 is in the second state, the second multi-way valve 60 is in the tenth state, and the stop valve 156 is in the closed state.
