[0032] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this application. It can be understood that the specific embodiments described herein are only used to explain this application, rather than limiting this application. Additionally, it should be noted that for the sake of description, only parts related to this application rather than all structures are shown in the accompanying drawings. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0033] Refer to Figure 1 , Figure 1 is a schematic structural diagram of an embodiment of the vehicle's thermal management system provided by this application. The thermal management system includes: a compressor 1, a first heat exchanger 2, a regenerator 3, a first throttling device 6, an evaporator 7, a gas-liquid separator 8, a first water pump 9, an electric heater 10, and a second heat exchanger 14.

[0034] The compressor 1 functions to compress and drive the refrigerant in the refrigerant circuit. The compressor 1 usually extracts the refrigerant from the low-pressure area, compresses it, and then sends it to the high-pressure area for cooling and condensation. Heat is dissipated to the air through the radiator fins, and the refrigerant also changes from a gaseous state to a liquid state, with the pressure increasing.

[0035] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers can be used as heaters, coolers, condensers, evaporators, and reboilers, etc.

[0036] During the process of cooling or pressurizing the saturated gas, some condensable gas components will form small liquid droplets and flow along with the gas. The function of the gas-liquid separator 8 is to process the gas containing a small amount of condensate to achieve condensate recovery or gas-phase purification. Its structure is generally a pressure vessel with relevant inlet components and droplet-trapping components inside. Generally, the gas exits from the upper part, and the liquid phase is collected from the lower part. Since the refrigerating oil will also be separated and accumulate at the bottom of the vapor-liquid separator during the process of separating the refrigerant liquid, there is an oil hole at the outlet pipe and the bottom of the vapor-liquid separator to ensure that the refrigerating oil can return to the compressor 1, thus avoiding oil shortage in the compressor 1.

[0037] The regenerator 3 is also called a gas-liquid heat exchanger. It is a heat exchange device that can use the refrigerant vapor coming out of the evaporator 7 to cool the high-pressure liquid before entering the evaporator 7, making the refrigerant liquid subcooled and the vapor superheated.

[0038] Among them, the first heat exchanger 2, the first end of the first heat exchange channel of the first heat exchanger 2 is connected to the output end of the compressor 1.

[0039] The regenerator 3, the first end of the high-pressure side of the regenerator 3 is connected to the second end of the first heat exchange channel of the first heat exchanger 2.

[0040] The first throttling device 6, the first end of the first throttling device 6 is connected to the second end of the high-pressure side of the regenerator 3.

[0041] The evaporator 7, the first end of the evaporator 7 is connected to the second end of the first throttling device 6. The evaporator 7 is arranged in the air-conditioning box.

[0042] The gas-liquid separator 8, the first end of the gas-liquid separator 8 is connected to the second end of the evaporator 7; the second end of the gas-liquid separator 8 is connected to the first end of the low-pressure side of the regenerator 3; among them, the second end of the low-pressure side of the regenerator 3 is connected to the input end of the compressor 1.

[0043] The first water pump 9, the output end of the first water pump 9 is connected to the first end of the second heat exchange channel of the first heat exchanger 2.

[0044] The electric heater 10, the first end of the electric heater 10 is connected to the second end of the second heat exchange channel of the first heat exchanger 2.

[0045] The second heat exchanger 14, the first end of the second heat exchanger 14 is connected to the second end of the electric heater 10; the second end of the second heat exchanger 14 is connected to the input end of the first water pump 9.

[0046] The first throttling device 6 can be an electronic expansion valve. The electronic expansion valve uses the electrical signal generated by the regulated parameter to control the voltage or current applied to the expansion valve, and further achieves the purpose of regulating the liquid supply amount. By controlling the opening degree of the first throttling device 6, the flow rate of the refrigerant can be controlled.

[0047] In some embodiments, the high-pressure side of the regenerator 3 can be defined as the first pressure side, and the low-pressure side of the regenerator 3 can be defined as the second pressure side, with the pressure of the first pressure side being greater than that of the second pressure side.

[0048] Wherein, in response to the first refrigeration instruction, the first throttling device 6 is turned on.

[0049] The compressor 1, the first heat exchanger 2, the high-pressure side of the regenerator 3, the first throttling device 6, the evaporator 7, the gas-liquid separator 8, and the low-pressure side of the regenerator 3 form a first refrigerant refrigeration circuit.

[0050] The first water pump 9, the first heat exchanger 2, the electric heater 10, and the second heat exchanger 14 form a first coolant refrigeration circuit.

[0051] In an application scenario, refer to Figure 2 , in response to the first refrigeration instruction, the first throttling device 6 is turned on, and the refrigerant starts from the compressor 1 and sequentially flows through the first heat exchanger 2, the high-pressure side of the regenerator 3, the first throttling device 6, the evaporator 7, the gas-liquid separator 8, and the low-pressure side of the regenerator 3, and then flows back to the compressor 1, cycling in this way, that is, flowing according to the first refrigerant refrigeration circuit.

[0052] And the coolant starts from the first water pump 9 and sequentially flows through the first heat exchanger 2, the electric heater 10, and the second heat exchanger 14, and then flows back to the first water pump 9, cycling in this way, that is, flowing according to the first coolant refrigeration circuit.

[0053] So that the air exchanges heat through the evaporator 7, thereby cooling the passenger compartment of the vehicle, and the refrigerant and the coolant exchange heat in the first heat exchanger 2.

[0054] The circulation mode in which the refrigerant circulates according to the above-mentioned first refrigerant refrigeration circuit and the coolant circulates according to the first coolant refrigeration circuit can be defined as the passenger compartment refrigeration mode.

[0055] In an application scenario, the user can select the passenger compartment refrigeration mode in the vehicle. In response to the passenger compartment refrigeration mode, the first throttling device 6 is turned on, and the refrigerant circulates according to the above-mentioned first refrigerant refrigeration circuit, and the coolant circulates according to the first coolant refrigeration circuit.

[0056] In this embodiment, by using the pipeline connection relationship of the compressor 1, the first heat exchanger 2, the regenerator 3, the first throttling device 6, the evaporator 7, the gas-liquid separator 8, the first water pump 9, the electric heater 10, and the second heat exchanger 14, in response to the first refrigeration instruction, the first throttling device 6 is turned on, and the refrigerant flows according to the first refrigerant refrigeration circuit, so that the air exchanges heat through the evaporator 7, thereby cooling the passenger compartment of the vehicle, and the refrigerant and the coolant exchange heat in the first heat exchanger 2, and the heated coolant releases heat in the second heat exchanger 14.

[0057] Since there are fewer components and throttling devices in the first refrigerant refrigeration circuit, the reliability of the manufacturing and operation of the refrigerant corresponding circuit is higher, and it is easier to perform an integrated design; secondly, each heat exchange component in the first refrigerant refrigeration circuit is a single-function heat exchanger, so its heat exchange efficiency can be guaranteed to be higher; thirdly, the refrigeration of the passenger compartment is directly cooled by the evaporator 7, so secondary heat exchange can be avoided and the heat exchange efficiency can be improved. Fourthly, there is no high-pressure heat exchanger led to the air conditioner box in the above-mentioned thermal management system, which can avoid the refrigerant with pressure pulsation flowing out of the compressor 1 flowing through the air conditioner box and causing noise deterioration.

[0058] Refer to Figure 3 , Figure 3 is a schematic structural diagram of another embodiment of the thermal management system of the vehicle provided by the present application. The thermal management system includes: a compressor 1, a first heat exchanger 2, a regenerator 3, a first throttling device 6, an evaporator 7, a gas-liquid separator 8, a first water pump 9, an electric heater 10, a second heat exchanger 14, a second throttling device 4, a cooler 5 and a second water pump 16.

[0059] Some components are connected according to the connection relationship in the above embodiment. The difference is that the first end of the second throttling device 4 is connected to the second end of the high-pressure side of the regenerator 3.

[0060] The first end of the first heat exchange channel of the cooler 5 is connected to the second end of the second throttling device 4, and the first end of the first heat exchange channel of the cooler 5 is connected to the first end of the gas-liquid separator 8.

[0061] The output end of the second water pump 16 is connected to the first end of the second heat exchange channel of the cooler 5 through a pipeline, and the input end of the second water pump 16 is connected to the second end of the second heat exchange channel of the cooler 5 through a pipeline. The pipeline flows through the battery module 17. The battery module 17 is used to provide electrical energy for the vehicle. The pipeline can cover the battery module 17 so that when the coolant flows through the battery module 17, it absorbs the heat generated by the operation of the battery module 17.

[0062] Wherein, in response to the second refrigeration instruction, the first throttling device 6 is cut off and the second throttling device 4 is turned on.

[0063] The compressor 1, the first heat exchanger 2, the high-pressure side of the regenerator 3, the second throttling device 4, the first heat exchange channel of the cooler 5, the gas-liquid separator 8 and the low-pressure side of the regenerator 3 constitute a second refrigerant refrigeration circuit.

[0064] The first water pump 9, the first heat exchanger 2, the electric heater 10 and the second heat exchanger 14 constitute a second coolant refrigeration circuit.

[0065] The second water pump 16 and the second heat exchange channel of the cooler 5 constitute a third coolant refrigeration circuit.

[0066] Among them, in response to the third refrigeration instruction, the first throttling device 6 and the second throttling device 4 are turned on.

[0067] The compressor 1, the first heat exchanger 2, the high-pressure side of the regenerator 3, the first throttling device 6, the evaporator 7, the gas-liquid separator 8, and the low-pressure side of the regenerator 3 form a third refrigerant refrigeration circuit.

[0068] The compressor 1, the first heat exchanger 2, the high-pressure side of the regenerator 3, the second throttling device 4, the first heat exchange channel of the cooler 5, the gas-liquid separator 8, and the low-pressure side of the regenerator 3 form a fourth refrigerant refrigeration circuit.

[0069] The first water pump 9, the first heat exchanger 2, the electric heater 10, and the second heat exchanger 14 form a fourth coolant refrigeration circuit.

[0070] The second water pump 16 and the second heat exchange channel of the cooler 5 form a fifth coolant refrigeration circuit.

[0071] In an application scenario, refer to Figure 4 , in response to the second refrigeration instruction, the first throttling device 6 is cut off, and the second throttling device 4 is turned on.

[0072] The refrigerant starts from the compressor 1, flows through the first heat exchanger 2, the high-pressure side of the regenerator 3, the second throttling device 4, the first heat exchange channel of the cooler 5, the gas-liquid separator 8, and the low-pressure side of the regenerator 3 in sequence, and then flows back to the compressor 1, circulating in this way, that is, flowing according to the second refrigerant refrigeration circuit.

[0073] The coolant starts from the first water pump 9, flows through the first heat exchanger 2, the electric heater 10, and the second heat exchanger 14 in sequence, and then flows back to the first water pump 9, circulating in this way, that is, flowing according to the second coolant refrigeration circuit.

[0074] In addition, the coolant also starts from the second water pump 16, flows through the second heat exchange channel of the cooler 5 in sequence, and then flows back to the second water pump 16, circulating in this way, that is, flowing according to the third coolant refrigeration circuit.

[0075] The refrigerant and the coolant exchange heat in the cooler 5. Furthermore, when the coolant with a reduced temperature after heat exchange flows through the battery module 17, it absorbs the heat of the battery module 17, thereby cooling the battery module 17. To a certain extent, the refrigerant recovers the heat generated by the battery module 17. And in the second coolant refrigeration circuit, the refrigerant and the coolant exchange heat in the first heat exchanger 2, and the coolant after heat exchange releases heat in the second heat exchanger 14.

[0076] This circulation mode in which the refrigerant circulates according to the above-mentioned second refrigerant refrigeration circuit, and the coolant circulates according to the second coolant refrigeration circuit and the third coolant refrigeration circuit can be defined as the battery refrigeration mode.

[0077] In this application scenario, using the pipeline connection relationships of the compressor 1, the first heat exchanger 2, the regenerator 3, the first throttling device 6, the evaporator 7, the gas-liquid separator 8, the first water pump 9, the electric heater 10, the second heat exchanger 14, the second throttling device 4, the cooler 5, and the second water pump 16, in response to the second refrigeration instruction, the first throttling device 6 is cut off and the second throttling device 4 is turned on. The refrigerant flows according to the second refrigeration circuit of the refrigerant, and the coolant flows according to the second refrigeration circuit and the third refrigeration circuit of the coolant. The refrigerant and the coolant exchange heat in the cooler 5, and then when the coolant flows through the battery module 17, it cools the battery module 17.

[0078] In an application scenario, refer to Figure 5 , in response to the third refrigeration instruction, the first throttling device 6 and the second throttling device 4 are turned on.

[0079] The refrigerant starts from the compressor 1 and sequentially flows through the first heat exchanger 2, the high-pressure side of the regenerator 3, the first throttling device 6, the evaporator 7, the gas-liquid separator 8, and the low-pressure side of the regenerator 3, and then flows back to the compressor 1, cycling in this way, that is, flowing according to the third refrigeration circuit of the refrigerant.

[0080] In addition, the refrigerant also starts from the compressor 1 and sequentially flows through the first heat exchanger 2, the high-pressure side of the regenerator 3, the second throttling device 4, the first heat exchange channel of the cooler 5, the gas-liquid separator 8, and the low-pressure side of the regenerator 3, and then flows back to the compressor 1, cycling in this way, that is, flowing according to the fourth refrigeration circuit of the refrigerant.

[0081] The coolant starts from the first water pump 9 and sequentially flows through the first heat exchanger 2, the electric heater 10, and the second heat exchanger 14, and then flows back to the first water pump 9, cycling in this way, that is, flowing according to the fourth refrigeration circuit of the coolant.

[0082] In addition, the coolant also starts from the second water pump 16 and sequentially flows through the second heat exchange channel of the cooler 5, and then flows back to the second water pump 16, cycling in this way, that is, flowing according to the fifth refrigeration circuit of the coolant.

[0083] The refrigerant and the coolant exchange heat in the cooler 5, and then the coolant with a reduced temperature after heat exchange absorbs the heat of the battery module 17 when flowing through the battery module 17, thereby cooling the battery module 17. To a certain extent, the refrigerant recovers the heat generated by the battery module 17. And in the fourth refrigeration circuit of the coolant, the refrigerant and the coolant exchange heat in the first heat exchanger 2, and the coolant after heat exchange releases heat in the second heat exchanger 14.

[0084] In addition, air passes through the evaporator 7 for heat exchange, and then the air after heat exchange flows into the passenger compartment to cool the passenger compartment of the vehicle.

[0085] The circulation mode in which the refrigerant circulates according to the above-mentioned refrigerant third refrigeration circuit and refrigerant fourth refrigeration circuit, and the coolant circulates according to the coolant fourth refrigeration circuit and coolant fifth refrigeration circuit can be defined as the passenger compartment refrigeration + battery refrigeration mode.

[0086] In this application scenario, using the pipeline connection relationship of the compressor 1, the first heat exchanger 2, the regenerator 3, the first throttling device 6, the evaporator 7, the gas-liquid separator 8, the first water pump 9, the electric heater 10, the second heat exchanger 14, the second throttling device 4, the cooler 5 and the second water pump 16, in response to the third refrigeration instruction, the first throttling device 6 and the second throttling device 4 are turned on. The refrigerant flows according to the refrigerant third refrigeration circuit and the refrigerant fourth refrigeration circuit. The coolant flows according to the coolant fourth refrigeration circuit and the coolant fifth refrigeration circuit. The refrigerant and the coolant exchange heat in the cooler 5, and then when the coolant flows through the battery module 17, it cools the battery module 17; and the air exchanges heat through the evaporator 7, and then cools the passenger compartment of the vehicle, and the refrigerant and the coolant exchange heat in the first heat exchanger 2.

[0087] Refer to Figure 6 , Figure 6 is a schematic structural diagram of another embodiment of the vehicle thermal management system provided by this application. The thermal management system includes: a compressor 1, a first heat exchanger 2, a regenerator 3, a first throttling device 6, an evaporator 7, a gas-liquid separator 8, a first water pump 9, an electric heater 10, a second heat exchanger 14, a second throttling device 4, a cooler 5, a second water pump 16, a heater core 13 and a first three-way valve 11.

[0090] Among them, in response to the dehumidification instruction, the first throttling device 6 is turned on, the second throttling device 4 is cut off, and the first interface and the third interface of the first three-way valve 11 are turned on.

[0091] The high-pressure side of the compressor 1, the first heat exchanger 2, the regenerator 3, the first throttling device 6, the evaporator 7, the gas-liquid separator 8 and the low-pressure side of the regenerator 3 constitute the refrigerant dehumidification circuit.

[0092] The first water pump 9, the first heat exchanger 2, the electric heater 10, the first three-way valve 11 and the heater core 13 constitute the coolant dehumidification circuit.

[0287] In this mode, the first electric fan 32 is turned on to enable heat exchange of air in the second heat exchanger 14, and then the defrosting of the third heat exchanger 24 is performed using the heat-exchanged air.

[0288] 14. Occupant compartment refrigeration + battery refrigeration + electronic control heat dissipation mode:

[0289] The refrigerant side circuit is arranged as follows: the compressor 1, the first heat exchanger 2, the high-pressure side of the regenerator 3, the first throttling device 6, the evaporator 7, the gas-liquid separator 8, the low-pressure side of the regenerator 3, and the compressor 1; and, the compressor 1, the first heat exchanger 2, the high-pressure side of the regenerator 3, the second throttling device 4, the first heat exchange channel of the cooler 5, the gas-liquid separator 8, the low-pressure side of the regenerator 3, and the compressor 1.

[0290] The coolant side circuit is arranged as follows: the first water pump 9, the first heat exchanger 2, the electric heater 10, the first three-way valve 11, the second heat exchanger 14, and the first water pump 9; and, the second water pump 16, the battery module 17, the third four-way valve 15, the second four-way valve 18, the first four-way valve 19, the second heat exchange channel of the cooler 5, the first stop valve 21, the fourth water pump 20, the first four-way valve 19, and the second water pump 16; and, the third water pump 25, the heat dissipation device 26, the electronic control module 27, the fourth stop valve 29, the third heat exchanger 24, the fifth stop valve 30, and the third water pump 25.

[0292] In this embodiment, the refrigerant circuit includes a compressor 1, a first heat exchanger 2, a regenerator 3, a second throttling device 4, a cooler 5, a first throttling device 6, an evaporator 7, and a gas-liquid separator 8. Since the components and throttling devices of the refrigerant circuit are fewer, the reliability of manufacturing and operation of the refrigerant circuit is higher, and it is easier to perform an integrated design, which is particularly suitable for; Secondly, each heat exchange component of the refrigerant circuit is a single-function heat exchanger, so higher heat exchange efficiency can be ensured; Thirdly, the refrigeration of the passenger compartment is directly achieved by the evaporator 7, so the reduction of efficiency caused by secondary heat exchange can be avoided. Fourthly, the passenger compartment and the battery each have separate heat exchanger components for refrigeration, namely the cooler 5 and the evaporator 7, and the cooling capacity distribution can be adjusted through the throttling devices in front of them respectively, so the system performance and flexibility can be ensured; Fifthly, there is no high-pressure heat exchanger led out to the HVAC in the system, which can avoid the refrigerant with pressure pulsation flowing through the air-conditioning box from the compressor 1, thus causing noise deterioration. Sixthly, the heating of the passenger compartment also includes heat pump heating. Although it is heated through secondary heat exchange, the heating auxiliary device, the electric heater 10, can be turned on in advance to ensure the heating rate and passenger comfort. When the water temperature rises, the electric heater 10 is turned off to ensure that the system can operate at high energy efficiency.

[0293] The first water circuit is formed by the first heat exchanger 2, the first water pump 9, the electric heater 10, the first three-way valve 11, the second three-way valve 12, the heater core 13, the second heat exchanger 14, and the third four-way valve 15. The electric heater 10 is used for auxiliary heating. The first heat exchanger 2 can be a heat pump heating heat exchanger. These two heating components are connected in series and then divided into two paths through the first three-way valve 11. When passing through the second heat exchanger 14, when the first heat exchanger 2 is a condenser or an air cooler to release heat to the external environment when refrigeration is required, and when passing through the branch of the second three-way valve 12, it can be proportionally distributed according to the heat requirements of the passenger compartment and the battery; the heater core 13 provides heat for the passenger compartment, and flowing through the third four-way valve 15 provides heat for the battery. Due to the existence of the electric heater 10, the situation of insufficient heat pump heat in the early stage can be solved, and at the same time, the problem of the heating speed for the passenger compartment and the battery is ensured.

[0294] The second water circuit is composed of the second water pump 16, the battery module 17, the third four-way valve 15, the second four-way valve 18, and the first four-way valve 19. The third four-way valve 15 can realize the series coupling of the first water circuit and the second water circuit, so as to realize the battery heating condition. The second four-way valve 18 can realize the coupling of the motor and the battery water circuit, which is used for heating the battery by the motor water circuit or for waste heat recovery. The first four-way valve 19 can realize the coupling of the second water circuit and the cooler 5 side, so as to realize battery refrigeration or waste heat recovery for the battery and the motor.

[0295] The third water circuit consists of a fourth water pump 20, a first four-way valve 19, a cooler 5, a first stop valve 21, a second stop valve 22, a third heat exchanger 24, and the second stop valve 22, and mainly realizes two functions. When flowing through the first stop valve 21, it is used for cooling the battery or recovering the waste heat of the electric control battery. When flowing through the third heat exchanger 24, it is used for absorbing heat from the outside in the heating condition. The third heat exchanger 24 is a heat exchanger shared with the fourth water circuit. The stop valves in this water circuit can be replaced with other valves to achieve the same function.

[0296] The fourth water circuit consists of a third water pump 25, a heat dissipation device 26, an electric control module 27, a second four-way valve 18, a sixth stop valve 28, a fourth stop valve 29, a fifth stop valve 30, and a third heat exchanger 24. Among them, the third heat exchanger 24 is a heat exchanger shared with the third water circuit. It mainly realizes two functions. When flowing through the second four-way valve 18, it is coupled with the second water circuit to realize the motor heating the battery or recovering waste heat. When flowing through the third heat exchanger 24, it realizes the electric control unit dissipating heat externally alone. Since when the fourth water circuit flows through the third heat exchanger 24, the cooler 5 of the third water circuit needs to cool the battery, and when the cooler 5 of the third water circuit flows through the third heat exchanger 24, it means that the system needs to absorb heat from the environment and the heat of the motor and the battery is insufficient. Therefore, the motor does not need to dissipate heat either. So, there will be no conflict in sharing the third heat exchanger 24 by the third and fourth water circuits and they can be shared. The stop valves in this water circuit can be replaced with other valves to achieve the same function.

[0297] Refer to Figure 24 , Figure 24 is a schematic structural diagram of an embodiment of an automobile provided by the present application. The automobile 200 includes a thermal management system 100. The thermal management system 100 is the thermal management system provided in any of the above embodiments.

[0298] The automobile 200 can be a pure electric vehicle or a hybrid electric vehicle.

[0299] In summary, for the thermal management system and vehicle provided by the present application, since the refrigerant circuit is simplified, the complex refrigerant-side flow and phase change are made simpler, while the reliability and stability of the system are further ensured, which is particularly suitable for high-pressure refrigeration systems. Since the designed heat exchange components on the refrigerant side are no longer dual-purpose and each heat exchanger is designed according to its own characteristics, good performance can be ensured. The internal condenser is omitted to prevent the refrigerant with large pressure pulsations just coming out of the compressor 1 from directly affecting the NVH (Noise, Vibration, Harshness) performance of the passenger compartment, thus improving the comfort of passengers. The motor water circuit and the battery water circuit can be coupled to solve the problem that the motor cannot heat the battery, and the waste heat of the motor can be utilized more efficiently, thereby increasing the cruising range. Since the direct electric heating efficiency is less than 1, while the heat pump system can achieve heating with a COP (coefficient of performance) greater than 1 and higher energy utilization, and the present system enables the heat pump system to directly heat the battery, the system energy efficiency can be improved and the impact on the cruising range can be reduced. The efficient recovery of the waste heat of the battery and the electronic control can be achieved simultaneously, improving the energy efficiency of the system and thus increasing the cruising range of the whole vehicle.

[0300] The above are only the embodiments of the present application, and do not limit the patent scope of the present application accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present application.
