[0057] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0058] The following is for reference. Figures 1-6 The present invention describes a thermal management system 100 according to an embodiment of the present invention, and also proposes a vehicle.

[0059] Example 1:

[0060] The thermal management system 100 includes an air conditioning system. Refrigerant circulates within the air conditioning system, and the air conditioning system can exchange heat with the heating circuit 50 through the condenser 71.

[0061] The thermal management system 100 further includes: a first control valve 61, which is connected to a high-pressure heat exchange circuit 10, a battery heat exchange circuit 20, a radiator circuit 30, a heat exchanger circuit 40, and a heating circuit 50. The first control valve 61 selectively connects to one or more of the high-pressure heat exchange circuit 10, the battery heat exchange circuit 20, the radiator circuit 30, the heat exchanger circuit 40, and the heating circuit 50, and the air conditioning system exchanges heat with the heat exchanger circuit 40 and the heating circuit 50.

[0062] For example, such as Figure 1 As shown, the first control valve 61 can connect the radiator circuit 30 and the high-pressure heat exchange circuit 10, so that the radiator circuit 30 and the high-pressure heat exchange circuit 10 form a closed loop. The heat generated by the high-pressure device is carried to the radiator circuit 30 by the coolant, thereby realizing the heat dissipation of the high-pressure device.

[0063] like Figure 2 and Figure 6 As shown, the first control valve 61 connects the two ends of the battery heat exchange circuit 20 and the two ends of the heat exchanger circuit 40, and connects the battery heat exchange circuit 20 and the heat exchanger circuit 40 in series. The heat exchanger 41 can absorb the heat of the battery pack 21 and transfer the heat to the air conditioning system. The heat is used for heating the crew cabin through the condenser 71 or for cooling through the radiator 31.

[0064] like Figure 3 As shown, the first control valve 61 can connect the radiator circuit 30, the high-pressure heat exchange circuit 10, and the battery heat exchange circuit 20. The high-pressure heat exchange circuit 10, the battery heat exchange circuit 20, and the radiator circuit 30 are connected in series. The coolant circulates between the radiator 31, the high-pressure heat exchange circuit 10, and the battery heat exchange circuit 20, thereby transporting the heat generated by the battery pack 21 and the high-voltage devices to the radiator 31 and dissipating it to the outside, thus achieving heat dissipation for the battery pack 21 and the high-voltage devices.

[0065] For example, such as Figure 5 As shown, the first control valve 61 can connect the high-pressure heat exchange circuit 10 and the heat exchanger circuit 40. The high-pressure heat exchange circuit 10 and the heat exchanger circuit 40 are connected in series to form a closed loop, which can transfer the waste heat generated by the high-pressure device to the refrigerant of the air conditioning system. The refrigerant releases heat at the condenser 71. When the condenser 71 is connected to the battery heat exchange circuit 20, the battery pack 21 can be heated.

[0066] The thermal management system 100 also includes a multi-port pipe 63, with both ends connected to the two valve ports of the first control valve 61, one end of the multi-port pipe 63 connected to the heating circuit 50, and the other end of the multi-port pipe 63 connected to the radiator circuit 30. The multi-port pipe 63 connects the condenser 71 and the radiator 31. When the air conditioning system is cooling, the refrigerant releases a large amount of heat at the condenser 71. The coolant absorbs this heat and dissipates it to the outside through the radiator 31. After releasing heat, the refrigerant flows from the condenser 71 to the evaporator 72, where it absorbs heat from the passenger compartment, thus cooling the passenger compartment.

[0067] Thus, by connecting multiple circuits through the first control valve 61 and the second control valve 62, the flow resistance in each working mode is reduced, the energy utilization rate is improved, and the energy utilization efficiency of the heat pump or heating circuit 50 is optimized.

[0068] like Figure 2 and Figure 3 As shown, the thermal management system 100 also includes a second control valve 62. One end of the second control valve 62 is connected to one port of the first control valve 61, another end of the second control valve 62 is connected to the radiator circuit 30, and yet another end of the second control valve 62 is connected to the heating circuit 50. The first control valve 61 and the second control valve 62 work together to connect the radiator 31 and the condenser 71 in series. The refrigerant can absorb heat from the battery pack 21 at the heat exchanger 41 or heat from the passenger compartment at the evaporator 72, and exchange heat with the coolant at the condenser 71, transferring this heat to the coolant. When the coolant flows through the radiator 31, it can be dissipated to the outside through the radiator 31, thereby cooling the battery pack 21 or the passenger compartment.

[0069] Combination Figures 1-6 As shown, the first control valve 61 includes: a first valve port, a second valve port, a third valve port, a fourth valve port, a fifth valve port, a sixth valve port, a seventh valve port, an eighth valve port, and a ninth valve port, wherein the first valve port is... Figures 1-6 The "a" in the middle; the second valve port is... Figures 1-6 The "b" in the figure refers to the third valve port. Figures 1-6 The "c" in the figure refers to the fourth valve port. Figures 1-6 The "d" in the figure refers to the fifth valve port. Figures 1-6 The "e" in the figure refers to the sixth valve port. Figures 1-6 The "f" in the text refers to the seventh valve port. Figures 1-6 The "g" in the middle; the eighth valve port is... Figures 1-6 The "h" in the middle; the ninth valve port is... Figures 1-6 The "i" in the text.

[0070] The second control valve 62 includes: a tenth valve port, an eleventh valve port, and a twelfth valve port, wherein the tenth valve port is... Figures 1-6 The "j" in the text; the eleventh valve port is... Figures 1-6 The "k" in the text; the twelfth valve port is... Figures 1-6 The "m" in it.

[0071] The first valve port is connected to one end of the high-pressure heat exchange circuit 10, the second valve port is connected to the other end of the radiator 31, the third and fourth valve ports are connected to both ends of the battery heat exchange circuit 20, the fifth and sixth valve ports are connected to both ends of the heat exchanger circuit 40, the seventh valve port is connected to the tenth valve port of the second control valve 62, the eleventh valve port is connected to one end of the heater core 51 and one end of the condenser 71, the twelfth valve port is connected to the other end of the heat exchange circuit of the motor 11, the other end of the heat exchange circuit of the motor 11 is also connected to the other end of the radiator 31, and the eighth valve port is connected to one end of the radiator 31.

[0072] Combination Figures 1-6 As shown, the multi-port pipe 63 includes a first port and a second port; the thermal management system 100 also includes a first branch 64 and a second branch 65. The first branch 64 is connected between the first port and one port of the first control valve 61, and the second branch 65 is connected between the second port and the other port of the first control valve 61. The first branch 64 is connected between the first port and the seventh port, and the second branch 65 is connected between the second port and the ninth port. Figure 4 As shown, the third valve port and the ninth valve port are connected, and the fourth valve port and the seventh valve port are connected. Then the battery heat exchange circuit 20 and the one-way valve 66 are connected in series so that the coolant flowing out of the battery heat exchange circuit 20 can flow back to the battery heat exchange circuit 20 from the one-way valve 66, thereby achieving uniform temperature of the battery pack 21.

[0073] like Figure 1 As shown, a one-way valve 66 is provided on the first branch 64. The one-way valve 66 is configured to allow coolant to flow from the first control valve 61 to the multi-port pipe 63. Specifically, the seventh valve port of the first control valve 61 is connected to one end of the one-way valve 66, and the other end of the one-way valve 66 is connected to the first pipe port. By providing the one-way valve 66 on the first branch 64, the coolant on the first branch 64 can only flow from the seventh valve port to the first pipe port.

[0074] The multi-port pipe 63 also includes a third port and a fourth port; the thermal management system 100 also includes a third branch 67, one end of which is connected to another end of the multi-port pipe 63, and the other end of which is connected to the radiator circuit 30 and another valve port of the first control valve 61; the fourth port is connected to the heating circuit 50. That is to say, the third branch 67 connects the one-way valve 66 and the eighth valve port, or the third branch 67 can connect the condenser 71 and the other end of the radiator 31, so that the coolant flows from the condenser 71 to the radiator 31, and the heat at the condenser 71 is dissipated to the outside through the radiator 31 to achieve cooling of the occupant cabin.

[0075] Furthermore, a shut-off valve 68 is installed on the third branch 67. One end of the shut-off valve 68 is connected to the multi-port pipe 63, and the other end of the shut-off valve 68 is connected to the other end of the radiator 31. When the eleventh and twelfth valve ports are connected, the shut-off valve 68 can connect to the other end of the radiator 31, so that the condenser 71 and the radiator 31 can be connected in series, allowing coolant to flow from the condenser 71 to the radiator 31, dissipating the heat at the condenser 71 to the outside through the radiator 31, thereby cooling the crew compartment.

[0076] According to some embodiments of this utility model, the heating circuit 50 includes: a condenser 71, an electric heater 52, and a heater core 51. The electric heater 52 and the heater core 51 are connected in series. One end of the condenser 71 is connected to the second control valve 62 and one end of the heater core 51. The other end of the condenser 71 is connected to the other end of the heater core 51 and the multi-way pipe 63. The condenser 71 can be part of both the air conditioning system and the heating circuit 50. When the air conditioning system is running, the condenser 71 generates heat, which can be transferred to the battery heat exchange circuit 20 or the heater core 51 through the first control valve 61 and the second control valve 62 to heat the battery pack 21 or the passenger compartment, thereby making reasonable use of the heat generated by the condenser 71.

[0077] One end of the heater core 51 is connected to one end of the condenser 71 and the second control valve 62, and the other end of the heater core 51 is connected to the other end of the condenser 71 and the fourth port of the multi-port pipe 63. The condenser 71 dissipates heat into the coolant, and the coolant flows through the heater core 51, thereby dissipating heat into the crew compartment to achieve crew compartment heating.

[0078] An electric heater 52 is installed between the heater core 51 and the condenser 71. The electric heater 52 can heat the coolant in the heating circuit 50, so that the electric heater 52 can provide heating when the air conditioning system is not running. The electric heater 52 can be a PTC heater.

[0079] The heating circuit 50 also includes a third water pump 53, which is located between one end of the condenser 71 and one end of the second control valve 62 and the heater core 51. The third water pump 53 can realize the circulation of coolant.

[0080] According to some embodiments of this utility model, the heat exchanger circuit 40 includes: a heat exchanger 41, both ends of which are connected to a first control valve 61, and the air conditioning system is connected to the heat exchanger 41; the air conditioning system includes: a compressor 73 and an evaporator 72, the compressor 73, the evaporator 72 and the condenser 71 are connected in series. That is, the refrigerant flows out from the compressor 73, releases heat at the condenser 71, and absorbs heat at the evaporator 72. The condenser 71 includes: a refrigerant flow channel and a coolant flow channel. The refrigerant flows in the refrigerant flow channel, and the coolant flows in the coolant flow channel. The refrigerant and the coolant exchange heat at the condenser 71, realizing the exchange of heat between the air conditioning system and the heating circuit 50.

[0081] In this configuration, heat exchanger 41 and evaporator 72 are connected in parallel and in series with condenser 71. Furthermore, since heat exchanger 41 and evaporator 72 are connected in parallel, the refrigerant can flow to heat exchanger 41 to absorb heat after releasing heat in condenser 71. The heat absorbed by the refrigerant from heat exchanger 41 can be transferred to heating circuit 50 at condenser 71 for heating the crew compartment; or, the refrigerant can flow to evaporator 72 to absorb heat after releasing heat in condenser 71.

[0082] According to some embodiments of this utility model, the radiator circuit 30 includes a radiator 31, one end of which is connected to a first control valve 61 and a multi-port pipe 63. Specifically, one end of the radiator 31 can be connected to an eighth valve port and one end of a shut-off valve 68, and the other end of the shut-off valve 68 is connected to a third pipe port. When the coolant flows through the radiator 31, if the temperature of the coolant is higher than the ambient temperature, the radiator 31 dissipates heat to the outside; if the temperature of the coolant is lower than the ambient temperature, the coolant absorbs ambient heat at the radiator 31.

[0083] Furthermore, the high-pressure heat exchange circuit 10 includes a motor 11, an electronic control unit 12, and a first water pump 13, which are connected in series. Specifically, the first water pump 13 is connected in series with the motor 11 and the electronic control unit 12. The first water pump 13 drives the coolant to circulate within the high-pressure heat exchange circuit 10, thereby facilitating heat dissipation for the motor 11 and the electronic control unit 12. If the temperature of the coolant flowing through the high-pressure heat exchange circuit 10 is higher than that of the motor 11, the coolant heats the motor 11; if the temperature of the coolant flowing through the high-pressure heat exchange circuit 10 is lower than that of the motor 11, the coolant cools the motor 11.

[0084] The first water pump 13 can realize the circulation of coolant.

[0085] The high-pressure heat exchange circuit 10 also includes a first temperature sensor, which is connected in series with the first water pump 13 and the motor 11. Specifically, the first temperature sensor can monitor the temperature of the coolant, and thus control the opening degree of the first water pump 13 based on the coolant temperature, thereby controlling the flow rate of the coolant. For example, when the coolant temperature is high, the opening degree of the first water pump 13 can be increased.

[0086] The battery heat exchange circuit 20 includes a second water pump 22 and a battery pack 21, which are connected in series. One end of the second water pump 22 is connected to a first control valve 61. The battery pack 21 and the second water pump 22 are connected in series, and the second water pump 22 drives the coolant to circulate within the battery pack 21, thereby facilitating heat absorption or dissipation in the battery pack 21. If the coolant flowing through the battery heat exchange circuit 20 is higher than the temperature of the battery pack 21, the coolant heats the battery pack 21; if the coolant flowing through the battery heat exchange circuit 20 is lower than the temperature of the battery pack 21, the coolant cools the battery pack 21.

[0088] According to some embodiments of this utility model, the thermal management system 100 further includes: an overflow tank 81 and a four-way pipe 82. The four-way pipe 82 is connected to the radiator circuit 30, the first control valve 61, the high-pressure heat exchange circuit 10, and the overflow tank 81, respectively. The radiator 31 is connected to the second valve port and the high-pressure heat exchange circuit 10 through the four-way pipe 82. One port of the four-way pipe 82 is connected to the other end of the radiator 31, another port of the four-way pipe 82 is connected to the overflow tank 81, yet another port of the four-way pipe 82 is connected to the second valve port, and yet another port of the four-way pipe 82 is connected to one end of the high-pressure heat exchange circuit 10.

Specifically, one end of the fourth branch is connected to another port of the four-way pipe 82, and the other end of the fourth branch is connected to the second valve port. Thus, the fourth branch can connect the other end of the radiator 31 to the second valve port, facilitating the series connection of the radiator 31 with the battery heat exchange circuit 20, the condenser 71, etc.

[0090] Example 2:

[0091] The thermal management system 100 includes an air conditioning system. Refrigerant circulates within the air conditioning system, and the air conditioning system can exchange heat with the heating circuit 50 through the condenser 71.

[0092] The thermal management system 100 further includes: a first control valve 61, which is connected to a high-pressure heat exchange circuit 10, a battery heat exchange circuit 20, a radiator circuit 30, a heat exchanger circuit 40, and a heating circuit 50.

The heat generated by the high-pressure device is carried to the radiator circuit 30 by the coolant, thereby realizing the heat dissipation of the high-pressure device.

[0094] like Figure 2 and Figure 6 As shown, the first control valve 61 connects the two ends of the battery heat exchange circuit 20 and the two ends of the heat exchanger circuit 40, and connects the battery heat exchange circuit 20 and the heat exchanger circuit 40 in series. The heat exchanger 41 can absorb the heat of the battery pack 21 and transfer the heat to the air conditioning system. The heat is used for heating the crew cabin through the condenser 71 or for cooling through the radiator 31.

[0095] like Figure 3 As shown, the first control valve 61 can connect the radiator circuit 30, the high-pressure heat exchange circuit 10, and the battery heat exchange circuit 20. The high-pressure heat exchange circuit 10, the battery heat exchange circuit 20, and the radiator circuit 30 are connected in series. The coolant circulates between the radiator 31, the high-pressure heat exchange circuit 10, and the battery heat exchange circuit 20, thereby transporting the heat generated by the battery pack 21 and the high-voltage devices to the radiator 31 and dissipating it to the outside, thus achieving heat dissipation for the battery pack 21 and the high-voltage devices.

[0096] For example, such as Figure 5 As shown, the first control valve 61 can connect the high-pressure heat exchange circuit 10 and the heat exchanger circuit 40. The high-pressure heat exchange circuit 10 and the heat exchanger circuit 40 are connected in series to form a closed loop, which can transfer the waste heat generated by the high-pressure device to the refrigerant of the air conditioning system. The refrigerant releases heat at the condenser 71. When the condenser 71 is connected to the battery heat exchange circuit 20, the battery pack 21 can be heated.

The multi-port pipe 63 connects the condenser 71 and the radiator 31. When the air conditioning system is cooling, the refrigerant releases a large amount of heat at the condenser 71. The coolant absorbs this heat and dissipates it to the outside through the radiator 31. After releasing heat, the refrigerant flows from the condenser 71 to the evaporator 72, where it absorbs heat from the passenger compartment, thus cooling the passenger compartment.

[0098] Thus, multiple circuits are connected through the first control valve 61 and the multi-way pipe 63, reducing the flow resistance in each working mode, improving energy utilization, and optimizing the energy utilization efficiency of the heat pump or heating circuit 50.

The refrigerant can absorb heat from the battery pack 21 at the heat exchanger 41 or heat from the passenger compartment at the evaporator 72, and exchange heat with the coolant at the condenser 71, transferring this heat to the coolant. When the coolant flows through the radiator 31, it can be dissipated to the outside through the radiator 31, thereby cooling the battery pack 21 or the passenger compartment.

The one-way valve 66 is configured to allow coolant to flow from the first control valve 61 to the multi-port pipe 63. Specifically, the seventh valve port of the first control valve 61 is connected to one end of the one-way valve 66, and the other end of the one-way valve 66 is connected to the first pipe port.

The other end of the condenser 71 is connected to the other end of the heater core 51 and the multi-way pipe 63. The condenser 71 can be part of both the air conditioning system and the heating circuit 50. When the air conditioning system is running, the condenser 71 generates heat, which can be transferred to the battery heat exchange circuit 20 or the heater core 51 through the first control valve 61 and the second control valve 62 to heat the battery pack 21 or the passenger compartment, thereby making reasonable use of the heat generated by the condenser 71.

[0108] One end of the heater core 51 is connected to one end of the condenser 71 and the second control valve 62, and the other end of the heater core 51 is connected to the other end of the condenser 71 and the fourth port of the multi-port pipe 63. The condenser 71 dissipates heat into the coolant, and the coolant flows through the heater core 51, thereby dissipating heat into the crew compartment to achieve crew compartment heating.

[0142] According to some embodiments of this utility model, the heat exchanger circuit 40 includes: a heat exchanger 41, both ends of which are connected to a first control valve 61, and the air conditioning system is connected to the heat exchanger 41; the air conditioning system includes: a compressor 73 and an evaporator 72, the compressor 73, the evaporator 72 and the condenser 71 are connected in series. That is, the refrigerant flows out from the compressor 73, releases heat at the condenser 71, and absorbs heat at the evaporator 72. The condenser 71 includes: a refrigerant flow channel and a coolant flow channel. The refrigerant flows in the refrigerant flow channel, and the coolant flows in the coolant flow channel. The refrigerant and the coolant exchange heat at the condenser 71, realizing the exchange of heat between the air conditioning system and the heating circuit 50.

[0143] In this configuration, heat exchanger 41 and evaporator 72 are connected in parallel and in series with condenser 71. Furthermore, since heat exchanger 41 and evaporator 72 are connected in parallel, the refrigerant can flow to heat exchanger 41 to absorb heat after releasing heat in condenser 71. The heat absorbed by the refrigerant from heat exchanger 41 can be transferred to heating circuit 50 at condenser 71 for heating the crew compartment; or, the refrigerant can flow to evaporator 72 to absorb heat after releasing heat in condenser 71.

[0144] According to some embodiments of this utility model, the radiator circuit 30 includes a radiator 31, one end of which is connected to a first control valve 61 and a multi-port pipe 63. Specifically, one end of the radiator 31 can be connected to an eighth valve port and one end of a shut-off valve 68, and the other end of the shut-off valve 68 is connected to a third pipe port. When the coolant flows through the radiator 31, if the temperature of the coolant is higher than the ambient temperature, the radiator 31 dissipates heat to the outside; if the temperature of the coolant is lower than the ambient temperature, the coolant absorbs ambient heat at the radiator 31.

[0145] Furthermore, the high-pressure heat exchange circuit 10 includes a motor 11, an electronic control unit 12, and a first water pump 13, which are connected in series. Specifically, the first water pump 13 is connected in series with the motor 11 and the electronic control unit 12. The first water pump 13 drives the coolant to circulate within the high-pressure heat exchange circuit 10, thereby facilitating heat dissipation for the motor 11 and the electronic control unit 12. If the temperature of the coolant flowing through the high-pressure heat exchange circuit 10 is higher than that of the motor 11, the coolant heats the motor 11; if the temperature of the coolant flowing through the high-pressure heat exchange circuit 10 is lower than that of the motor 11, the coolant cools the motor 11.

[0146] The first water pump 13 can realize the circulation of coolant.

[0147] The high-pressure heat exchange circuit 10 also includes a first temperature sensor, which is connected in series with the first water pump 13 and the motor 11. Specifically, the first temperature sensor can monitor the temperature of the coolant, and thus control the opening degree of the first water pump 13 based on the coolant temperature, thereby controlling the flow rate of the coolant. For example, when the coolant temperature is high, the opening degree of the first water pump 13 can be increased.

[0148] The battery heat exchange circuit 20 includes a second water pump 22 and a battery pack 21, which are connected in series. One end of the second water pump 22 is connected to a first control valve 61. The battery pack 21 and the second water pump 22 are connected in series, and the second water pump 22 drives the coolant to circulate within the battery pack 21, thereby facilitating heat absorption or dissipation in the battery pack 21. If the coolant flowing through the battery heat exchange circuit 20 is higher than the temperature of the battery pack 21, the coolant heats the battery pack 21; if the coolant flowing through the battery heat exchange circuit 20 is lower than the temperature of the battery pack 21, the coolant cools the battery pack 21.

[0149] The second water pump 22 can realize the circulation of coolant.

[0150] According to some embodiments of this utility model, the thermal management system 100 further includes: an overflow tank 81 and a four-way pipe 82. The four-way pipe 82 is connected to the radiator circuit 30, the first control valve 61, the high-pressure heat exchange circuit 10, and the overflow tank 81, respectively. The radiator 31 is connected to the second valve port and the high-pressure heat exchange circuit 10 through the four-way pipe 82. One port of the four-way pipe 82 is connected to the other end of the radiator 31, another port of the four-way pipe 82 is connected to the overflow tank 81, yet another port of the four-way pipe 82 is connected to the second valve port, and yet another port of the four-way pipe 82 is connected to one end of the high-pressure heat exchange circuit 10.

[0151] Furthermore, the thermal management system 100 also includes a fourth branch, one end of which is connected to the first control valve 61, and the other end of which is connected to the four-way pipe 82. Specifically, one end of the fourth branch is connected to another port of the four-way pipe 82, and the other end of the fourth branch is connected to the second valve port. Thus, the fourth branch can connect the other end of the radiator 31 to the second valve port, facilitating the series connection of the radiator 31 with the battery heat exchange circuit 20, the condenser 71, etc.

[0152] The vehicle according to a second aspect embodiment of the present invention includes a thermal management system 100. This system reduces flow resistance in various operating modes, improving energy efficiency; it also enables proportional adjustment of the battery pack 21 and passenger compartment under dual heating conditions, optimizing the energy utilization efficiency of the heat pump or heating circuit 50.

[0153] The following reference Figures 2-6 Five operating modes of the thermal management system 100 according to an embodiment of the present invention are described.

[0154] Reference Figure 2 As shown, the thermal management system 100 operates in mode one:

[0155] Loop 1: Radiator 31 → First water pump 13 → Electrical control 12 → Motor 11 → First control valve 61 → Radiator 31. The first valve port and the eighth valve port are connected, meaning the first control valve 61 is connected in series with the radiator loop 30 and the high-pressure heat exchange loop 10, dissipating the waste heat generated by the motor 11 and electrical control 12 to the outside through the radiator 31, thus cooling the motor 11 and electrical control 12.

[0156] Loop 2: Second water pump 22 → Battery pack 21 → First control valve 61 → Heat exchanger 41 → First control valve 61 → Second water pump 22. The third and fifth valve ports are connected, and the fourth and sixth valve ports are connected. That is, the battery heat exchange loop 20 and the heat exchanger 41 are connected in series via the first control valve 61. Specifically, the heat exchanger 41, battery pack 21, and second water pump 22 are connected in series, allowing the coolant to circulate between the heat exchanger 41 and the battery pack 21. The heat exchanger 41 absorbs heat from the battery pack 21 and exchanges heat with the air conditioning system, thus cooling the battery pack 21.

[0157] Circuit 3: Condenser 71 → Electric heater 52 → Shut-off valve 68 → Radiator 31 → First control valve 61 → Second control valve 62 → Third water pump 53 → Condenser 71.

[0158] The second valve port is connected to the seventh valve port, the seventh valve port is connected to the tenth valve port, and the tenth valve port is connected to the eleventh valve port, thereby connecting the other end of the radiator 31 to one end of the heating circuit 50. The shut-off valve 68 connects the other end of the heating circuit 50 to one end of the radiator 31, thereby connecting the radiator 31 and the condenser 71 in series. The heat absorbed by the condenser 71 can be dissipated to the outside through the radiator 31.

[0159] Circuit 2 and Circuit 3 can be connected simultaneously. In the air conditioning system, the compressor 73, condenser 71 and heat exchanger 41 are connected in series. The refrigerant can absorb the heat of the battery pack 21 in the heat exchanger 41 and exchange heat with the coolant in the condenser 71, transferring this part of the heat to the coolant. When the coolant flows through the radiator 31, it can be dissipated to the outside through the radiator 31, thereby cooling the battery pack 21.

[0160] Circuit 3 can be connected independently. When the air conditioning system is cooling, the compressor 73, condenser 71 and evaporator 72 are connected in series. The refrigerant absorbs heat from the passenger compartment at the evaporator 72 and releases a large amount of heat at the condenser 71. The coolant absorbs this heat and dissipates it to the outside through the radiator 31, thereby cooling the passenger compartment.

[0161] Reference Figure 3As shown, the second working mode of the thermal management system 100 is as follows:

[0162] Circuit 1: Radiator 31 → First water pump 13 → Electrical control 12 → Motor 11 → First control valve 61 → Second water pump 22 → Battery pack 21 → Radiator 31.

[0163] The first valve port is connected to the third valve port, and the fourth valve port is connected to the eighth valve port. That is to say, the first control valve 61 is connected in series with the radiator circuit 30, the high-pressure heat exchange circuit 10 and the battery heat exchange circuit 20. The radiator 31, the motor 11, the electronic control 12 and the battery pack 21 are connected in series, so that the heat generated by the motor 11 and the electronic control 12 and the heat of the battery pack 21 are carried to the radiator 31 by the coolant, thereby achieving the cooling of the motor 11 and the battery pack 21.

[0164] Circuit 2: Radiator 31 → First water pump 13 → Second control valve 62 → Third water pump 53 → Condenser 71 → Electric heater 52 → Shut-off valve 68 → Radiator 31.

[0165] Among them, the eleventh valve port and the twelfth valve port are connected, that is, the second control valve 62 is connected in series with the radiator circuit 30 and the condenser 71. When the air conditioning system is cooling, the compressor 73, the condenser 71 and the evaporator 72 are connected in series in sequence. The refrigerant absorbs the heat of the passenger compartment at the evaporator 72 and releases a large amount of heat at the condenser 71. The coolant absorbs the heat and dissipates it to the outside through the radiator 31, thereby cooling the passenger compartment.

[0166] Furthermore, when the condenser 71 has low heat dissipation requirements, only one water pump can be turned on (either the first water pump 13 or the third water pump 53). When the condenser 71 has high heat dissipation requirements, two water pumps (the first water pump 13 and the third water pump 53) need to be operated simultaneously, and the opening degree of the two water pumps should be adjusted according to the heat dissipation requirements of the condenser 71.

[0167] Reference Figure 4 As shown, the thermal management system 100 operates in mode three:

[0168] Loop 1: Heat exchanger 41 → First control valve 61 → Radiator 31 → First water pump 13 → Electrical control 12 → Motor 11 → First control valve 61 → Heat exchanger 41.

[0169] The first valve port and the sixth valve port are connected, and the fifth valve port and the eighth valve port are connected. That is, the first control valve 61 is connected in series with the radiator circuit 30 and the heat exchanger circuit 40. The radiator 31, the first water pump 13, the electrical control 12, the motor 11 and the heat exchanger 41 are connected in series. Driven by the first water pump 13, the coolant flows through the radiator 31, the electrical control 12 and the motor 11 in sequence, and absorbs the heat of the radiator 31 and the motor 11. The absorbed heat is transferred to the refrigerant circulating in the air conditioning system through the heat exchanger 41.

[0170] Circuit 2: Condenser 71 → Electric heater 52 → Warm air core 51 → Third water pump 53 → Condenser 71.

[0171] At the condenser 71, the refrigerant of the air conditioning system exchanges heat with the coolant, transferring heat to the coolant flowing through the condenser 71. Driven by the third water pump 53, the coolant circulates between the condenser 71, the electric heater 52, and the warm air core 51, thereby using the waste heat generated by the motor 11 and the electronic control 12 to heat the passenger compartment.

[0172] Circuit 3: Condenser 71 → Electric heater 52 → First control valve 61 → Second water pump 22 → Battery pack 21 → First control valve 61 → Second control valve 62 → Third water pump 53 → Condenser 71.

[0173] The third valve port is connected to the ninth valve port, the fourth valve port is connected to the seventh valve port, and the tenth valve port is connected to the eleventh valve port. The first control valve 61 and the second control valve 62 are connected in series with the battery pack 21 and the condenser 71. The coolant flowing out of the condenser 71 is divided into two parts: one part flows to the heater core 51 to heat the passenger compartment; the other part flows to the battery pack 21 to heat the battery pack 21. This ensures the normal operation of the battery pack 21 in low-temperature environments.

[0174] Circuit 4: Battery pack 21 → Check valve 66 → Second water pump 22 → Battery pack 21. The coolant flowing out of battery pack 21 is divided into two parts. One part flows to condenser 71, and the other part returns to battery pack 21 through check valve 66. The coolant flowing out of check valve 66 mixes with the part of coolant flowing out of condenser 71 before flowing back to battery pack 21, to prevent the temperature of the coolant flowing through battery pack 21 from becoming too high and causing an accident.

[0175] Reference Figure 5 As shown, the thermal management system 100 operates in mode four:

[0176] Loop 1: Heat exchanger 41 → First control valve 61 → Electrical control 12 → Motor 11 → First control valve 61 → Heat exchanger 41.

[0177] The first valve port and the fifth valve port are connected, and the sixth valve port and the second valve port are connected. That is, the first control valve 61 is connected in series with the high-pressure heat exchange circuit 10 and the heat exchanger circuit 40. The first water pump 13, the electrical control 12, the motor 11 and the heat exchanger 41 are connected in series. Driven by the first water pump 13, the coolant flows through the electrical control 12 and the motor 11 in sequence, and absorbs the heat of the motor 11. The absorbed heat is transferred to the refrigerant circulating in the air conditioning system through the heat exchanger 41.

[0178] Circuit 2: Condenser 71 → Electric heater 52 → Warm air core 51 → Third water pump 53 → Condenser 71.

[0179] At the condenser 71, the refrigerant of the air conditioning system exchanges heat with the coolant, transferring heat to the coolant flowing through the condenser 71. Driven by the third water pump 53, the coolant circulates between the condenser 71, the electric heater 52, and the warm air core 51, thereby using the waste heat generated by the motor 11 and the electronic control 12 to heat the passenger compartment.

[0180] Circuit 3: Condenser 71 → Electric heater 52 → First control valve 61 → Second water pump 22 → Battery pack 21 → First control valve 61 → Second control valve 62 → Third water pump 53 → Condenser 71.

[0181] The third valve port is connected to the ninth valve port, the fourth valve port is connected to the seventh valve port, and the tenth valve port is connected to the eleventh valve port. The first control valve 61 and the second control valve 62 are connected in series with the battery pack 21 and the condenser 71. The coolant flowing out of the condenser 71 is divided into two parts: one part flows to the heater core 51 to heat the passenger compartment; the other part flows to the battery pack 21 to heat the battery pack 21. This ensures the normal operation of the battery pack 21 in low-temperature environments.

[0182] Circuit 4: Battery pack 21 → Check valve 66 → Second water pump 22 → Battery pack 21.

[0183] The coolant flowing out of the battery pack 21 is divided into two parts. One part flows to the condenser 71, and the other part returns to the battery pack 21 through the one-way valve 66. The coolant flowing out of the one-way valve 66 mixes with the part of coolant flowing out of the condenser 71 before flowing back to the battery pack 21, so as to avoid the temperature of the coolant flowing through the battery pack 21 being too high and causing an accident.

[0184] Reference Figure 6 As shown, the thermal management system 100 operates in mode five:

[0185] Loop 1: Second water pump 22 → Battery pack 21 → First control valve 61 → Heat exchanger 41 → First control valve 61 → Second water pump 22.

[0186] The third and fifth valve ports are connected, and the fourth and sixth valve ports are connected. In other words, the battery heat exchange circuit 20 and the heat exchanger 41 are connected in series through the first control valve 61. That is, the heat exchanger 41, the battery pack 21, and the second water pump 22 are connected in series, so that the coolant circulates between the heat exchanger 41 and the battery pack 21. The heat exchanger 41 can absorb the heat of the battery pack 21 and exchange heat with the air conditioning system, thereby achieving the cooling of the battery pack 21.

[0187] Circuit 2: First water pump 13 → Electrical control 12 → Motor 11 → First control valve 61 → Check valve 66 → First control valve 61 → First water pump 13.

[0188] The first valve port is connected to the seventh valve port, and the second valve port is connected to the ninth valve port. That is, the first control valve 61 and the one-way valve 66 are connected to the two ends of the high-pressure hot water exchange circuit to realize the heat storage of the motor 11.

[0189] Loop 3: First water pump 13 → Electrical control 12 → Motor 11 → First control valve 61 → Second control valve 62 → Third water pump 53 → Condenser 71 → Electric heater 52 → First control valve 61 → First water pump 13.

[0190] The first valve port is connected to the seventh valve port, the second valve port is connected to the ninth valve port, and the tenth valve port is connected to the eleventh valve port. The first control valve 61 and the second control valve 62 are connected in series with the condenser 71, the electric heater 52, and the motor 11.

[0191] Heat exchanger 41 absorbs heat from battery pack 21 and releases it into the air conditioning system. At condenser 71, the refrigerant and coolant of the air conditioning system exchange heat, transferring heat to the coolant flowing through condenser 71. Driven by the third water pump 53, the coolant circulates between condenser 71, electric heater 52, and motor 11. In cold environments, before starting the vehicle, the heat from the air conditioning system can be used to preheat motor 11, enabling normal operation of motor 11 in cold conditions.

[0192] This enables functions such as heating / cooling of battery pack 21, heating / cooling of passenger compartment, cooling of motor 11, battery temperature equalization, and dual heating / dual cooling, reducing flow resistance in various operating modes, improving energy utilization on the coolant side, and making it suitable for platform-based integration.
