[0028] The application will be further described below with reference to the drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the application described below can be combined with each other as long as there is no conflict. The embodiments described below by reference to the drawings are exemplary and are intended to explain the application, but cannot be understood as limiting the application.

[0029] As shown in Figures 1 to 5 The present embodiment provides a heat management system, comprising: a chiller 13, the chiller 13 comprising a first chiller pipeline 131 and a second chiller pipeline 132 which can exchange heat with each other.

[0030] Further, the heat management system further comprises a refrigerant circuit, the refrigerant circuit comprising a compressor 11, a water-cooled condenser 12 and the first chiller pipeline 131 which are connected in series.

[0031] In the present embodiment, as shown in Figure 1 and Figure 2 The refrigerant circuit further comprises an expansion valve 14, which is arranged in the pipeline between the outlet of the water-cooled condenser 12 and the inlet of the first chiller pipeline 131 of the chiller 13. The expansion valve 14 mainly plays a role of throttling, pressure reduction and flow regulation in the refrigerant circuit.

[0032] It should be understood that the liquid refrigerant at medium temperature and high pressure becomes gas-liquid mixed state refrigerant at low temperature and low pressure after throttling through the expansion valve 14, and then absorbs heat in the chiller 13 to become gaseous refrigerant at low temperature and low pressure to achieve refrigeration effect; at the same time, the expansion valve 14 controls the valve flow through the change of superheat degree at the outlet of the first chiller pipeline 131 of the chiller 13 to ensure that the outlet of the first chiller pipeline 131 of the chiller 13 is completely gaseous refrigerant.

[0033] In the present embodiment, the flow path of the refrigerant in the refrigerant circuit is: starting from the compressor 11, first flowing through the water-cooled condenser 12, then flowing through the expansion valve 14, then flowing through the first chiller pipeline 131 of the chiller 13, and finally returning to the compressor 11.

[0034] It should be understood that the refrigerant flowing through the compressor 11 becomes high-temperature and high-pressure refrigerant vapor; then, flowing through the water-cooled condenser 12 becomes medium-temperature and high-pressure liquid refrigerant; then, flowing through the expansion valve 14 becomes low-temperature and low-pressure gas-liquid mixed refrigerant; and finally, flowing through the first refrigeration machine pipeline 131 of the refrigeration machine 13 becomes low-temperature and low-pressure gaseous refrigerant and then flows into the compressor 11 for the next cycle.

[0035] Further, the thermal management system further comprises a refrigeration water circuit, the refrigeration water circuit comprising the passenger cabin air conditioning core assembly and the second refrigeration machine pipeline 132 connected in series to form a passenger cabin refrigeration water circuit; the battery pack heat exchange assembly 22 and the second refrigeration machine pipeline 132 connected in series to form a battery refrigeration water circuit; and the electric drive cooling module 23 and the second refrigeration machine pipeline 132 connected in series to form an electric drive refrigeration water circuit. The battery pack heat exchange assembly 22 is connected in parallel with the passenger cabin air conditioning core assembly, and the electric drive cooling module 23 is connected in parallel with the passenger cabin air conditioning core assembly.

[0036] In the embodiment, the passenger cabin air conditioning core assembly, the battery pack heat exchange assembly 22 and the electric drive cooling module 23 are connected in parallel with each other to facilitate separate refrigeration or heating.

[0037] It should be understood that the first refrigeration machine pipeline 131 and the second refrigeration machine pipeline 132 of the refrigeration machine 13 are two independent pipelines, the first refrigeration machine pipeline 131 is arranged in the refrigerant circuit and the refrigerant flows in the first refrigeration machine pipeline 131, and the second refrigeration machine pipeline 132 is arranged in the refrigeration water circuit and water flows in the second refrigeration machine pipeline 132. Meanwhile, the first refrigeration machine pipeline 131 and the second refrigeration machine pipeline 132 can exchange heat to absorb or release heat.

[0038] In the embodiment, the refrigerant needs to absorb heat to convert from low-temperature and low-pressure gas-liquid mixed state to low-temperature and low-pressure gaseous state in the first refrigeration machine pipeline 131, therefore, the refrigerant in the first refrigeration machine pipeline 131 absorbs the heat released by the water in the second refrigeration machine pipeline 132, so that the heat of the water in the second refrigeration machine pipeline 132 is reduced to achieve the effect of refrigeration for the refrigeration water circuit.

[0039] In the embodiment, the refrigerant circuit and the refrigeration water circuit can exchange heat through the first refrigeration machine pipeline 131 and the second refrigeration machine pipeline 132 of the refrigeration machine 13, and the passenger cabin air conditioning core assembly, the battery pack heat exchange assembly 22 and the electric drive cooling module 23 are all connected in series with the second refrigeration machine pipeline 132 of the refrigeration machine 13, so that the passenger cabin air conditioning core assembly, the battery pack heat exchange assembly 22 and the electric drive cooling module 23 can all realize refrigeration through the refrigeration machine 13 of the refrigeration water circuit, without the need for additional evaporators to realize refrigeration, which is conducive to simplifying the architecture of the thermal management system, and further facilitating the management and distribution of heat of the thermal management system and reducing the energy consumption of the thermal management system.

[0040] In the embodiment, the water-cooled condenser 12 comprises a first condenser pipeline 121 and a second condenser pipeline 122 which can exchange heat with each other, and the refrigerant circuit comprises the compressor 11, the first condenser pipeline 121 and the first refrigeration pipeline 131 which are connected in series. Figure 1 and Figure 2 As shown in the figure, the water-cooled condenser 12 comprises a first condenser pipeline 121 and a second condenser pipeline 122 which can exchange heat with each other, and the refrigerant circuit comprises the compressor 11, the first condenser pipeline 121 and the first refrigeration pipeline 131 which are connected in series.

[0041] Further, the thermal management system further comprises a heating water circuit, the heating water circuit comprises the passenger cabin air conditioning core assembly and the second condenser pipeline 122 which are connected in series to form a passenger cabin heating water circuit; the battery pack heat exchange assembly 22 and the second condenser pipeline 122 which are connected in series to form a battery heating water circuit; and the electric drive cooling module 23 and the second condenser pipeline 122 which are connected in series to form an electric drive heat dissipation water circuit.

[0042] In the embodiment, the first condenser pipeline 121 and the second condenser pipeline 122 of the water-cooled condenser 12 are two pipelines which are independent of each other, the first condenser pipeline 121 is arranged in the refrigerant circuit, and the refrigerant flows in the first condenser pipeline 121; the second condenser pipeline 122 is arranged in the heating water circuit, and water flows in the second condenser pipeline 122. At the same time, the first condenser pipeline 121 and the second condenser pipeline 122 can exchange heat to absorb heat or release heat.

[0043] It should be understood that, since the refrigerant needs to release heat when converting from high-temperature and high-pressure refrigerant vapor to medium-temperature and high-pressure liquid refrigerant in the first condenser pipeline 121, the refrigerant in the first condenser pipeline 121 will release heat, and the water in the second condenser pipeline 122 will absorb the heat released by the refrigerant in the first condenser pipeline 121, so that the heat of the water in the second condenser pipeline 122 increases, thereby achieving the effect of heating the heating water circuit.

[0044] In the embodiment, the refrigerant circuit and the heating water circuit can exchange heat through the first condenser pipeline 121 and the second condenser pipeline 122 of the water-cooled condenser 12, and the passenger cabin air conditioning core assembly, the battery pack heat exchange assembly 22 and the electric drive cooling module 23 are all connected in series with the second condenser pipeline 122 of the water-cooled condenser 12, so that the passenger cabin air conditioning core assembly, the battery pack heat exchange assembly 22 and the electric drive cooling module 23 can all realize heating through the water-cooled condenser 12 of the heating water circuit, without the need to use multiple water-cooled condensers 12 for heating, which is conducive to simplifying the architecture of the thermal management system, and further facilitating the management and distribution of heat of the thermal management system and reducing the energy consumption of the thermal management system.

[0045] It should be understood that the passenger cabin air conditioning core assembly is part of the air conditioner, and the passenger cabin air conditioning core assembly is used in series with the refrigerating machine 13 or the water-cooled condenser 12 to refrigerate or heat the passenger cabin; the battery pack heat exchange assembly 22 is part of the battery pack, and the battery pack heat exchange assembly 22 is used in series with the refrigerating machine 13 or the water-cooled condenser 12 to refrigerate or heat the battery pack; and the electric drive cooling module 23 is part of the electric drive, and the electric drive cooling module 23 is used in series with the refrigerating machine 13 or the water-cooled condenser 12 to refrigerate or heat the electric drive.

[0046] In the embodiment, the passenger cabin air conditioning core assembly includes a first air conditioning core 21 and a second air conditioning core 24.

[0048] In the embodiment, the passenger cabin heating water circuit includes the first air conditioning core 21 and the second condenser pipeline 122 connected in series with each other to form a first passenger cabin heating water circuit; and the second air conditioning core 24 and the second condenser pipeline 122 connected in series with each other to form a second passenger cabin heating water circuit; and the first air conditioning core 21 and the second air conditioning core 24 are connected in parallel.

[0049] In the embodiment, the first air conditioning core 21 and the second air conditioning core 24 can be selected to be connected in series with the refrigerating machine 13 or the water-cooled condenser 12, that is, the first air conditioning core 21 and the second air conditioning core 24 can be selected to be in a refrigeration mode or a heating mode. The first air conditioning core 21 and the second air conditioning core 24 correspond to different regions of the passenger cabin, so that the passenger cabin can be heated or refrigerated according to different needs of the passengers in the vehicle, and different regions of the passenger cabin can be controlled individually.

[0050] It should be understood that since the existing passenger cabin is usually a multi-temperature zone structure, the thermal management system needs to control different regions of the passenger cabin individually. In order to control different regions of the passenger cabin individually, only the number of air conditioning cores needs to be increased, avoiding the difficulty in matching the thermal management system due to the use of multiple evaporators, thereby improving the adaptability and flexibility of the thermal management system.

[0051] For example, the first air conditioning core 21 corresponds to the front seat region of the passenger cabin, and the second air conditioning core 24 corresponds to the rear seat region of the passenger cabin, and the front seat region and the rear seat region can be selected to be heated or refrigerated.

The inlet of the electric drive cooling module 23 is connected to the eleventh flow valve port 311, and the outlet of the electric drive cooling module 23 is connected to the twelfth flow valve port 312.

The motor radiator 25 and the fan a can reduce the heat of the electric drive heat dissipation water circuit or the electric drive refrigeration water circuit to achieve the effect of refrigeration.

[0078] It should be understood that, since the electric drive does not need heating, after the electric drive cooling module 23 is connected in series with the second condenser pipeline 122 of the water-cooled condenser 12, the electric drive heat dissipation water circuit needs to reduce the heat of the water circuit through the motor radiator 25 and the fan a, thereby reducing the heat of the thermal management system, so as to refrigerate the passenger compartment and the battery pack.

[0079] In the embodiment, in combination with Figure 1 As shown in the figure, the thermal management system further comprises a motor water pump 29 arranged between the outlet of the electric drive cooling module 23 and the inlet of the motor radiator 25. The motor water pump 29 is used to provide flow for the electric drive heat dissipation water circuit and the electric drive refrigeration water circuit.

[0080] In the embodiment, when the heating water circuit needs to heat, the heating water circuit can fully absorb the waste heat of the electric drive and other waste heat of the thermal management system, which is beneficial to improve the heating efficiency of the thermal management system, thereby reducing the energy consumption of the thermal management system.
