[0052] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0053] Reference below Figure 1-Figure 10 A heat exchange module and a heat management system according to embodiments of the present invention are described.

[0054] Figure 1 is a block diagram of a heat exchange module according to an embodiment of the present utility model, such as Figure 1 As shown, the heat exchange module 10 of the embodiment of the utility model includes a battery thermal management water circuit 101 and an electric heating water circuit 102 .

[0055] Among them, the battery thermal management water circuit 101 is used for thermal management of the battery pack, and the electric heating water circuit 102 is used for heating the passenger compartment through electrical energy.

[0056] In the embodiment of the utility model, the electric heating water circuit 102 can be connected with the battery thermal management water circuit 101. That is, in the embodiment, the electric heating water circuit 102 is directly connected with the battery thermal management water circuit 101, without the need for another heat exchange element such as a plate heat exchanger to perform heat exchange. Further, in the embodiment, the connection between the two can be a controllable mode or a direct connection mode.

[0057] According to the heat exchange module 10 of the embodiment of the utility model, the electric heating water circuit 102 can be directly connected to the battery thermal management water circuit 101, so as to realize direct heat exchange between the electric heating water circuit 102 and the battery thermal management water circuit 101. Compared with the plate heat exchanger, the battery thermal management efficiency can be improved and the waste of heat source can be reduced.

[0058] In some embodiments, the electric heating water circuit 102 can be selectively connected to the battery thermal management water circuit 101. That is, the electric heating water circuit 102 can be connected to the battery thermal management water circuit 101, or the electric heating water circuit 102 can also not be connected to the battery thermal management water circuit 101, and whether the two are connected can be selected according to the battery thermal management requirements.

[0059] Figure 2 is a block diagram of a heat exchange module according to an embodiment of the present utility model, such as Figure 2 As shown, the heat exchange module 10 further includes a switching valve 103 .

[0060] The battery thermal management water circuit 101 is used for thermal management of the battery, for example, heating or cooling the battery pack. The electric heating water circuit 102 is used for heating the passenger compartment.

[0061] In an embodiment of the utility model, the electric heating water circuit 102 and the battery thermal management water circuit 101 can be directly connected, that is, when the battery needs electric heating auxiliary heating, the circulating fluid heated by the electric heating water circuit 102 can directly flow into the battery thermal management water circuit 101 to achieve direct heating of the battery.

[0062] The switching valve 103 is disposed at the connection between the electric heating water path 102 and the battery thermal management water path 101 to control the connection state between the electric heating water path 102 and the battery thermal management water path 101 .

[0063] Specifically, when the battery thermal management water circuit 101 itself can meet the battery heating demand, the switching valve 103 can cut off the connection between the electric heating water circuit 102 and the battery thermal management water circuit 101. Alternatively, when the battery thermal management water circuit 101 itself cannot meet the battery heating demand and the auxiliary heating of the electric heating water circuit 102 is required, the switching valve 103 can be switched to the connection state between the electric heating water circuit 102 and the battery thermal management water circuit 101, so as to realize the direct connection between the electric heating water circuit 102 and the battery thermal management water circuit 101.

[0064] According to the heat exchange module 10 of the embodiment of the utility model, the electric heating water circuit 102 is directly connected to the battery thermal management water circuit 101, and the connectivity between the electric heating water circuit 102 and the battery thermal management water circuit 101 is controlled by the switching valve 103. When the battery has a demand for electric heating, direct heat exchange between the electric heating water circuit 102 and the battery thermal management water circuit 101 can be achieved. Compared with the plate heat exchanger, the battery thermal management efficiency can be improved and the waste of heat source can be reduced.

[0065] In an embodiment, the switching valve 103 can be implemented by one component or a combination of multiple components. When the battery thermal management water circuit 101 has a demand for electric heating assistance, the switching valve 103 controls the battery thermal management water circuit 101 and the electric heating water circuit 102 to be directly connected, so that the battery thermal management water circuit 101 and the electric heating water circuit 102 constitute a circulation path for battery heating, thereby heating the battery.

[0066] In some embodiments, Figure 3 is a schematic diagram of a thermal management system according to an embodiment of the utility model, such as Figure 3 As shown, the switching valve 103 may include a first three-way valve 11 .

[0067] Among them, the first three-way valve 11 includes a first valve port, a second valve port and a third valve port. The first valve port is connected to the first end of the battery thermal management water circuit 101, the second valve port is connected to the electric heating water circuit 102, and the third valve port is connected to the second end of the battery thermal management water circuit 101.

[0068] Specifically, when the battery pack requires electric heating assistance, the first valve port of the first three-way valve 11 is connected to the second valve port, so that the electric heating water circuit 102 is directly connected to the battery thermal management water circuit 101, forming a circulation path for heating the battery.

[0069] It should be noted that, in the embodiment, the first end and the second end of the battery thermal management water channel 101 may be the terminal ends of the battery thermal management water channel 101 , or may be the ends somewhere in the middle.

[0070] In other embodiments, the switching valve 103 may also be implemented by a plurality of switching valves. For example, the switching valve 103 includes a first switching valve, a second switching valve, and a third switching valve.

[0071] The first end of the first switch valve is connected to the first end of the battery thermal management water circuit 101; the first end of the second switch valve is connected to the second end of the first switch valve, and the second end of the second switch valve is connected to the electric heating water circuit 102; the first end of the third switch valve is respectively connected to the second end of the first switch valve and the first end of the second switch valve, and the second end of the third switch valve is connected to the second end of the battery thermal management water circuit 101.

[0072] Specifically, when the battery thermal management water circuit 101 itself can meet the battery heating demand, the first switch valve and the third switch valve are connected, the second switch valve is cut off, and the battery thermal management water circuit 101 and the electric heating water circuit 102 circulate independently. When the battery thermal management water circuit 101 itself cannot meet the battery heating demand, the first switch valve and the second switch valve are connected, and the third switch valve is cut off, so that the electric heating water circuit 102 is directly connected to the battery thermal management water circuit 101, forming a circulation path for heating the battery.

[0073] like Figure 3 As shown, the battery thermal management water circuit 101 includes a battery pack 26 and a thermal management water pump 27. The battery pack and the thermal management water circuit are located between a first end of the battery thermal management water circuit 101 and a second end of the battery thermal management water circuit 101.

[0074] Specifically, when the battery pack needs to be heated or cooled, the thermal management water pump 27 is operated, and the water in the battery thermal management water circuit 101 begins to circulate, thereby achieving thermal management of the battery pack. If the battery thermal management water circuit 101 itself can meet the needs of the battery pack, the first valve port of the first three-way valve 11 is connected to the third valve port, otherwise, the first valve port of the first three-way valve 11 is connected to the second valve port, so that the battery thermal management water circuit 101 is connected to the electric heating water circuit 102, and the battery pack is heated together.

[0075] like Figure 3 As shown, the battery thermal management water circuit 101 also includes a plate heat exchanger 17, which is used to exchange heat with the air conditioning system. That is, when the electric heating water circuit 102 and the battery thermal management water circuit 101 cannot meet the battery thermal management requirements, or when the battery thermal management water circuit 101 cannot meet the battery thermal management requirements, the plate heat exchanger 17 can also be used to exchange heat with the air conditioning system, thereby increasing the battery thermal management path and realizing more thermal management modes.

[0076] Furthermore, if Figure 3 As shown, the heat exchange module 10 also includes a one-way valve 34, the input end of the one-way valve 34 is connected to the switching valve 103, and the output end of the one-way valve 34 is connected to the electric heating water circuit 102. Specifically, for example, the one-way valve 34 is arranged between the switching valve 103, such as the first three-way valve 11, and the electric heating water circuit 102, and the output end of the one-way valve 34 is connected to the electric heating water circuit 102. Therefore, when the electric heating water circuit 102 is connected to the battery thermal management water circuit 101, the refrigerant in the electric heating water circuit 102 and the battery thermal management water circuit 101 can flow in one direction, that is, the refrigerant enters the electric heating water circuit 102 and is heated and then returns to the battery thermal management water circuit 101 to meet the heating demand of the battery pack 26.

[0077] For another example, the one-way valve 34 is disposed between the switching valve 103, such as the second switch valve, and the electric heating water circuit 102, and the output end of the one-way valve 34 is connected to the electric heating water circuit 102. When the second switch valve is turned off, the battery thermal management water circuit 101 and the electric heating water circuit 102 circulate independently, and when the second switch valve is connected, the one-way valve 34 allows the refrigerant to flow in one direction, that is, from the battery thermal management water circuit 101 to the electric heating water circuit 102.

[0078] In an embodiment, Figure 3As shown, the input end of the battery pack water circuit is connected to the output end of the thermal management water pump 27 , the output end of the battery pack water circuit is connected to the first end of the switching valve 103 , and the input end of the thermal management water pump 27 is connected to the third end of the switching valve 103 .

[0079] The thermal management water pump 27 may be a water pump device for circulating and promoting the flow of thermal management water in the battery thermal management water path 101. The thermal management water pump 27 may return the thermal management water to the battery pack 26 for circulation through the operation of the water pump. Figure 2 As shown in FIG. 1 , the thermal management water pump 27 is connected to the third valve port of the first three-way valve 11 , and can control the flow direction of the thermal management water.

[0080] Furthermore, in some embodiments, the battery pack water circuit may include a water circulation plate, a water inlet pipe and a water outlet pipe. The battery pack is suitable for being arranged on the water circulation plate, the water circulation plate is provided with a circulating water circuit, and the water circulation plate is used to adjust the temperature of the battery pack; the water inlet pipe and the water outlet pipe are both connected to the circulating water circuit, the water inlet pipe is connected to the thermal management water pump, and the water outlet pipe is connected to the first end of the switching control valve, so as to realize the thermal management of the battery pack.

[0081] like Figure 3 As shown, the heat exchange module 10 can also include a second three-way valve 12, a first valve port of the second three-way valve 12 is connected to a first end of the electric heating water circuit 102, a second valve port of the second three-way valve 12 is respectively connected to an output end of the one-way valve 34 and a second end of the electric heating water circuit 102, and a third valve port of the second three-way valve 12 is respectively connected to a switching valve 103 and a battery thermal management water circuit 101.

[0082] The electric heating water circuit 102 includes an electric heating unit 28, a heater core 29 and a heating water pump 30. The electric heating unit 28, the heater core 29 and the heating water pump 30 are located between a first end of the electric heating water circuit 102 and a second end of the electric heating water circuit 102.

[0083] The electric heating unit 28 may be a device for converting electric energy into thermal energy. The warm air core 29 may be a component for transferring the heat generated by the electric heating unit 28 to the air. The heating water pump 30 may be a water pump for circulating hot water.

[0084] For example, the first valve port of the second three-way valve 12 is connected to the first end of the heater core 29, the second valve port of the second three-way valve 12 is connected to the first end of the heating water pump 30 and the output end of the one-way valve 34, the third valve port of the second three-way valve 12 is connected to the third end of the switching control valve 103, such as the third valve port of the first three-way valve 11, and the second end of the battery thermal management water circuit 101, and the second end of the heater core 29 is connected to the first end of the electric heating unit 28. Through the design of the electric heating water circuit 102, the system can provide additional heating support for the passenger compartment by converting electrical energy into thermal energy, and the direct connection between the electric heating water circuit 102 and the battery thermal management water circuit 101 can be achieved through the switching control valve and the second three-way valve 12.

[0085] like Figure 3 As shown, the heat exchange module 10 also includes an engine water circuit, the engine water circuit includes an engine 31 , and the engine water circuit can be selectively connected to the electric heating water circuit 102 .

[0086] like Figure 3 As shown, the heat exchange module 10 also includes a four-way valve 13, a first valve port of the four-way valve 13 is connected to the third end of the electric heating water circuit 102, a second valve port of the four-way valve 13 is connected to the fourth end of the electric heating water circuit 102, a third valve port of the four-way valve 13 is connected to the first port of the engine 31, and a fourth valve port of the four-way valve 13 is connected to the second port of the engine 31.

[0087] For example, the first valve port of the four-way valve 13 is connected to the second end of the heating water pump 30, the second valve port of the four-way valve 13 is connected to the second end of the electric heating unit 28, and the third valve port of the four-way valve 13 and the fourth valve port of the four-way valve 13 are both connected to the engine water circuit.

[0088] like Figure 3 As shown, the first port of the engine 31 is connected to the third valve port of the four-way valve 13 , and the second port of the engine 31 is connected to the fourth valve port of the four-way valve 13 .

[0089] Specifically, the refrigerant passes through the cooling channel inside the engine 31, absorbs the heat generated by the engine 31, and keeps the engine 31 within a suitable operating temperature range. The refrigerant after absorbing heat can transfer heat to the passenger compartment as needed under the control of the four-way valve 13, thereby heating the passenger compartment. In addition, when the electric heating water circuit 102 is connected to the battery thermal management water circuit 101, the engine water circuit, the electric heating water circuit 102 and the battery thermal management water circuit 101 can form a circulating water circuit for battery heating to meet the battery heating requirements.

[0090] In other embodiments, the function of the four-way valve can also be achieved by a combination of multiple switch valves.

[0091] For example, the heat exchange module 10 further includes a fourth switch valve, a fifth switch valve, a sixth switch valve and a seventh switch valve.

[0092] The first end of the fourth switch valve is connected to the third end of the electric heating water circuit 102; the fifth switch valve, the first end of the fifth switch valve is connected to the fourth end of the electric heating water circuit 102; the sixth switch valve, the first end of the sixth switch valve is connected to the first port of the engine; the seventh switch valve, the first end of the seventh switch valve is connected to the second port of the engine; wherein, the second end of the fourth switch valve is respectively connected to the second end of the fifth switch valve and the second end of the seventh switch valve, and the second end of the sixth switch valve is connected to the second end of the fifth switch valve and the second end of the seventh switch valve.

[0093] Specifically, the switching states of the four switching valves can be controlled according to the thermal management requirements of the battery pack so that the engine water circuit is connected or disconnected with the electric heating water circuit 102 .

[0094] In a specific embodiment, Figure 3 As shown, the heating water pump 30 is located between the first end of the electric heating water circuit 102 and the third end of the electric heating water circuit 102, and the electric heating unit 28 and the warm air core 29 are located between the second end of the electric heating water circuit 102 and the fourth end of the electric heating water circuit 102.

[0095] In the embodiment, the heat exchange module 10 further includes a sensor and a controller, wherein the sensor is used to collect the temperature of the passenger compartment and the battery temperature; the controller is connected to the sensor, the switching control valve, such as the first three-way valve 11, the second three-way valve 12 and the four-way valve 13, and is used to control the connection state of the valve ports of the switching control valve, the second three-way valve 12 and the four-way valve 13 according to the temperature of the passenger compartment and / or the battery temperature. Specifically, in the following embodiments, how to control each valve based on various working conditions and thermal management requirements is specifically described.

[0096] Based on the heat exchange module of the above embodiment, a second embodiment of the present invention proposes a thermal management system.

[0098] According to the thermal management system 1 of the present invention, by adopting the heat exchange module 10 of the above embodiment, the thermal management efficiency of the battery can be improved and the heat waste can be reduced.

[0099] Further, in an embodiment, Figure 3As shown, the thermal management system 1 of the embodiment of the utility model may also include an air conditioning system. The air conditioning system exchanges heat with the battery thermal management water path 101 through the plate heat exchanger 17 of the battery thermal management water path 101 in the heat exchange module 10 .

[0100] Among them, the air-conditioning system mainly meets the heating and cooling needs of the cabin, providing a comfortable ambient temperature for the cabin occupants.

[0101] The plate heat exchanger is connected to the air conditioning system and the battery thermal management water circuit 101 respectively to achieve heat exchange between the air conditioning system and the battery thermal management water circuit 101. That is, the air conditioning system and the battery thermal management water circuit 101 are combined through the heat exchange component to achieve heat exchange between the two, which can comprehensively consider the cabin temperature and the battery temperature to meet the thermal requirements of both. In an embodiment, the heat exchange component can be a heat exchanger, such as but not limited to a plate heat exchanger or other heat exchange devices with heat exchange function.

[0102] According to the thermal management system 1 of the embodiment of the utility model, the air-conditioning system, the battery thermal management water circuit 101 and the electric heating water circuit 102 are combined through the switching valve 103 and the plate heat exchanger 17, and the refrigerant path can be switched by setting the switching valve 103, so as to realize the switching and integrated connection of the three thermal management circuits, thereby realizing flexible switching of different heating modes, so that the system can select the most suitable heat energy source and transfer path according to the actual situation, realize the comprehensive management of vehicle thermal energy, improve energy utilization efficiency, and avoid waste of thermal energy.

[0103] Furthermore, in the embodiment, the plate heat exchanger 17 includes a first interface and a second interface connected to each other and a third interface and a fourth interface connected to each other; the air conditioning system is connected to both the first interface and the second interface; and the battery thermal management water circuit 101 is connected in series to the third interface and the fourth interface.

[0104] Specifically, when the air conditioning system is heating the cabin, it can perform heat exchange with the battery thermal management water circuit 101 through the plate heat exchanger to achieve the purpose of cooling the battery.

[0105] The thermal management system 1 of the embodiment of the utility model can realize the switching of the refrigerant path of the battery thermal management water circuit 101 and the electric heating water circuit 102 by setting the switching valve 103, and can realize the switching and integrated connection of the three thermal management circuits of the battery thermal management water circuit 101, the electric heating water circuit 102 and the air-conditioning system in combination with the heat exchange component, so as to realize the flexible switching of different heating modes, improve the energy utilization efficiency and avoid the waste of heat energy.

[0106] In some embodiments, according to the battery thermal management requirements and the passenger compartment requirements, the first three-way valve 11, the second three-way valve 12 and the four-way valve 13 can realize the connection or switching of any circuit in the air-conditioning system, the battery thermal management water circuit 101, the electric heating water circuit 102 and the engine water circuit.

[0107] The air conditioning system may refer to a closed-circuit system in a hybrid vehicle that is responsible for the operation of the air conditioning system, in which the air conditioning refrigerant is used as a heat transfer medium to complete the cooling and heating process through a circulating flow.

[0108] The battery thermal management water circuit 101 may refer to a water circuit system used to manage battery heat in a hybrid vehicle. In a hybrid vehicle, the battery is an important component, and its performance and life are affected by temperature. The battery thermal management water circuit 101 may control and adjust the temperature of the battery through water circulation to maintain the battery within a suitable operating temperature range, thereby improving the safety and reliability of the battery and extending the battery life.

[0109] The electric heating water circuit 102 may refer to a water circuit system that uses electric heating technology to achieve heating of the passenger compartment of a hybrid vehicle. In an embodiment, the electric heating technology may include PTC (Positive Temperature Coefficient) heating, wherein the PTC heater uses a thermistor material with a positive temperature coefficient. The thermistor material in the PTC heater has a special resistance property, and when power is turned on, its resistance value increases with the increase in temperature. Specifically, when the electric heating water circuit 102 needs to provide heat, current passes through the PTC heater, generating heat that is transferred to the circulating water flow, and then the hot water is transported to the passenger compartment, thereby providing a comfortable passenger compartment temperature in a low temperature environment.

[0110] The engine water circuit can be a method of using the cooling water of the engine 31 in the hybrid vehicle to provide heat energy for vehicle heating. In the hybrid vehicle, the heat generated by the engine 31 can be recovered and utilized, and the cooling water of the engine 31 is transferred to the heating system of the passenger compartment through a corresponding heat exchange device, thereby achieving heating of the passenger compartment.

[0111] In some embodiments, the first three-way valve 11 and the second three-way valve 12 have three valve ports respectively, and the four-way valve 13 has four valve ports, which are used to control the flow direction and distribution of the fluid.

[0112] Among them, the first valve port of the second three-way valve 12 and the second valve port of the second three-way valve 12 are both connected to the electric heating water circuit 102, the third valve port of the second three-way valve 12 is connected to the third valve port of the first three-way valve 11, and the third valve port of the second three-way valve 12 is also connected to the battery thermal management water circuit 101. The first valve port of the four-way valve 13 and the second valve port of the four-way valve 13 are both connected to the electric heating water circuit 102, and the third valve port of the four-way valve 13 and the fourth valve port of the four-way valve 13 are both connected to the engine water circuit.

[0113] In some embodiments, the controller is connected to the first three-way valve 11, the second three-way valve 12 and the four-way valve 13, and is used to start at least one heating mode among the electric heating water circuit 102, the battery thermal management water circuit 101, the engine water circuit and the air-conditioning system.

[0114] Specifically, Figure 3 As shown, at the beginning, each water circuit is in the default setting state. The battery thermal management water circuit 101, the electric heating water circuit 102 and the engine water circuit are circulated separately. At this time, the first valve port and the third valve port of the first three-way valve 11 are opened, and the first valve port and the second valve port of the second three-way valve 12 are opened. The four-way valve 13 is used to control the flow direction of the engine water circuit. In the default setting state, the four-way valve 13 connects the first valve port and the second valve port, and connects the third valve port and the fourth valve port at the same time to form a small cycle. Then, by obtaining information such as the vehicle working mode, the heating demand of the passenger compartment and the cooling and heating demand of the battery, the controller judges and selects the appropriate heating method. According to the selected heating method, the controller will control the valve port connection state in the valve body of the first three-way valve 11, the second three-way valve 12 and the four-way valve 13 accordingly to switch the water circuit connection. At the same time, according to the selected heating method, the system will distribute the heat energy to the passenger compartment or the battery for heating accordingly to achieve a comfortable heating effect or thermal management of the battery.

[0115] According to the thermal management system 1 of the embodiment of the utility model, by setting the valve port connection states of the first three-way valve 11, the second three-way valve 12 and the four-way valve 13 based on the changes in the vehicle working mode, the heating demand of the passenger compartment and the cooling and heating demand of the battery, the air-conditioning system, the battery thermal management water circuit 101, the electric heating water circuit 102 and the engine water circuit can be connected or isolated to each other to achieve flexible switching of different heating methods, which means that the system can select the most suitable heat energy source and transfer path according to actual conditions, thereby realizing comprehensive management of vehicle thermal energy, improving energy utilization efficiency and avoiding waste of thermal energy.

[0116] In some embodiments, Figure 5As shown, the controller includes an air conditioning control module 36 , a PTC control module 37 , a compressor 14 , an ECM (Engine Control Module) control module 39 , a BMS (Battery Management System) control module 40 , and a VCU (Vehicle Control Unit) control module 41 .

[0117] Among them, the air conditioning control module 36 can collect and control some components through hard lines, including the heating water pump 30, the thermal management water pump 27, the three-way valve, the four-way valve 13, the electronic expansion valve 43 (i.e. the electronic expansion valve on the evaporator side, the electronic expansion valve on the plate exchanger side, and the electronic expansion valve on the outdoor condenser side), the solenoid valve 42, the temperature sensor 44 (i.e. the outdoor temperature sensor, the indoor temperature sensor, the channel sensor, the compressor outlet temperature sensor, the evaporator outlet temperature sensor), the pressure sensor 45 and the plate exchanger outlet PT (Pressure Transducer, pressure sensor) sensor 46.

[0118] In some embodiments, different modules and components communicate via hardwired connections or via a CAN (Controller Area Network) network. Specifically, the air conditioning control module 36 communicates with the ECM control module 39, the BMS control module 40, the VCU control module 41, the compressor 14, and the PTC control module 37 via hardwired connections. The engine water temperature sensor is connected to the ECM control module 39 via hardwires, while the battery pack water temperature sensor is connected to the BMS control module 40 via hardwires. Through these communication connections, information can be exchanged, data and control signals can be transmitted between the various modules and components.

[0119] The design of this communication block diagram enables the various components in the system to work together. For example, the air conditioning control module 36 can control the heating water pump 30, the thermal management water pump 27, the three-way valve, the four-way valve 13, the electronic expansion valve 43, the solenoid valve 42 and other components according to the information from the ECM control module 39 and the BMS control module 40 to realize the operation of the thermal management system 1. In addition, sensors such as the temperature sensor 44 and the pressure sensor 45 can provide real-time temperature and pressure data for the controller to monitor and adjust.

[0120] In some embodiments, the air conditioning system may be composed of multiple components, including but not limited to a compressor 14, a condenser, an evaporator 24, a liquid storage desiccant 32, a coaxial tube 33, a plate heat exchanger 17, a one-way valve 34, a solenoid valve 42, and a throttling unit (such as an electronic expansion valve 43), etc. These components are interconnected through pipes and connectors to form a closed circulation path for circulating and regulating the flow of the refrigerant.

[0121] In some embodiments, the compressor 14 is used to suck low-temperature and low-pressure refrigerant gas into the system, and convert it into high-temperature and high-pressure refrigerant gas after compression. Through the operation of the compressor 14, the temperature and pressure of the refrigerant are increased, providing the necessary energy for the subsequent condensation and heating process. The condenser is used to release heat from the high-temperature and high-pressure refrigerant gas through contact with the outside air, so that it is cooled and converted into a high-temperature and high-pressure refrigerant liquid. In the condenser, the refrigerant can be in contact with the pipes and cooling fins of the condenser, so that heat is transferred from the refrigerant to the outside air, thereby cooling the refrigerant and converting it into a liquid state. The evaporator 24 is used to pass the high-temperature and high-pressure refrigerant liquid through the pipes of the evaporator 24, contact with the air in the vehicle and absorb the heat in the vehicle, so that the refrigerant evaporates from the liquid state to a low-temperature and low-pressure refrigerant gas.

[0122] In some embodiments, the liquid storage desiccant 32 can be a desiccant used to absorb moisture and impurities in the refrigerant circuit, keep the refrigerant circuit dry and clean, and prevent moisture and impurities from negatively affecting the performance and durability of the system. The coaxial tube 33 can be a pipe structure for heat exchange, consisting of two coaxial pipes inside and outside. In the air-conditioning system, the coaxial tube 33 can be used for heat exchange between the condenser and the evaporator 24. The inner tube is used to transfer the refrigerant, absorb heat and evaporate in the evaporator 24, while the outer tube is used to transfer heat and release heat from the condenser to the outside. Through the heat exchange of the coaxial tube 33, the temperature of the refrigerant can be adjusted and regulated to realize the cooling and heating functions of the air-conditioning system.

[0123] In some embodiments, the plate heat exchanger 17 is used to achieve heat transfer between the refrigerant and the medium. The plate heat exchanger 17 can be composed of a series of metal plates arranged in parallel, and the heat exchange between the refrigerant and the medium is achieved through the channels between the plates. The function of the plate heat exchanger 17 can be to optimize energy transfer, improve thermal efficiency, and enable the system to cool or heat efficiently.

[0124] In some embodiments, the one-way valve 34 is a valve used to ensure that the fluid flows in a specified direction and prevent backflow to maintain the normal operation of the system. The solenoid valve 42 is used to control the flow of refrigerant or other media. By controlling the electromagnetic coil of the solenoid valve 42, the valve can be opened or closed to control the flow of the fluid. The throttling unit is used to limit the cross-sectional area of ​​the fluid flow, thereby controlling the flow rate and pressure. In the thermal management system 1, the expansion valve is one of the common throttling units. It is installed in the refrigerant flow circuit to form a pressure difference between the high-pressure side and the low-pressure side, and control the flow rate and pressure of the refrigerant by adjusting the opening of the valve port.

[0125] In some embodiments, the air conditioning system includes: a heat pump water heat source sub-loop.

[0126] The heat pump water heat source sub-loop is connected to the first interface and the second interface of the plate heat exchanger 17 for heating the passenger compartment and cooling the battery.

[0127] Specifically, the heat pump water heat source sub-circuit uses heat pump technology to absorb heat from the environment, and then transfers the heat to the passenger compartment for heating to provide a comfortable heating effect. At the same time, it is also connected to the battery thermal management water circuit 101 to cool the battery by heat transfer to maintain the appropriate temperature of the battery and improve the performance and life of the battery. The heat pump wind heat source sub-circuit is used to heat the passenger compartment. Specifically, in the heat pump wind heat source sub-circuit, the refrigerant absorbs heat from the external environment through heat pump technology and transfers the heat to the passenger compartment for heating. In this way, the temperature in the passenger compartment can be adjusted and controlled to obtain a comfortable riding experience.

[0128] like Figure 6 As shown, the heat pump water heat source sub-circuit includes: a compressor 14, an internal condenser 15, a first solenoid valve 16 and a first throttling unit 18. These components together constitute the heating path of the heat pump water heat source sub-circuit.

[0129] Specifically, in the heat pump water heat source sub-loop, the exhaust port of the compressor 14 is connected to the input port of the internal condenser 15. The compressor 14 compresses the refrigerant gas to increase its temperature and pressure, and then transfers the heat to the internal condenser 15. The output port of the internal condenser 15 is connected to the first end of the first solenoid valve 16. The internal condenser 15 cools the high-temperature and high-pressure refrigerant gas and converts it into a high-temperature and high-pressure condensate, and then transmits it to the first solenoid valve 16. The second end of the first solenoid valve 16 is connected to the first end of the first throttling unit 18. The first solenoid valve 16 controls the flow of the condensate and guides it to the first throttling unit 18. The second end of the first throttling unit 18 is connected to the first interface of the plate heat exchanger 17. The first throttling unit 18 reduces the pressure of the condensate by restricting the flow of the condensate and guides it to the plate heat exchanger 17.

[0130] The third interface and the fourth interface of the plate heat exchanger 17 are connected in series in the battery thermal management water circuit 101. The second interface of the plate heat exchanger 17 is connected to the return air port of the compressor 14, and the heat of the condensate is transferred to the reflux refrigerant gas, which is then compressed and discharged by the compressor 14. In this way, the cycle is realized, that is, the plate heat exchanger 17 can transfer the remaining heat to the passenger compartment for heating. In this way, the heat resources can be utilized to the maximum extent, the energy utilization efficiency can be improved, and the flexibility and performance of the system can be ensured. The fourth interface of the plate heat exchanger 17 is connected to the battery thermal management water circuit 101, and the third interface of the plate heat exchanger 17 is connected to the second valve port of the first three-way valve 11. The air conditioning system and the battery thermal management water circuit 101 are heat exchanged through the plate heat exchanger. The heat generated by the air conditioning system for heating the cabin is heat exchanged through the plate heat exchanger 17 to generate cold energy and then transfer the cold energy to the battery thermal management water circuit 101, thereby cooling the battery.

[0131] Through such a design, the heat pump water heat source sub-circuit realizes the compression, condensation, throttling and heat exchange process of the refrigerant through the combination of the compressor 14, the internal condenser 15, the first solenoid valve 16, the plate heat exchanger 17 and the first throttling unit 18. It can absorb heat from the environment and transfer the heat to the passenger compartment through the heat exchanger to provide a heating effect, and exchange heat with the battery thermal management water circuit 101 to cool the battery. Thereby optimizing thermal management and energy utilization.

[0132] In some embodiments, the air conditioning system further includes a heat pump wind heat source sub-circuit, and the heat pump wind heat source sub-circuit is used to heat the passenger compartment.

[0133] Specifically, in the heat pump wind heat source sub-loop, the refrigerant absorbs heat from the external environment through heat pump technology, and transfers the heat to the passenger compartment for heating. In this way, the temperature in the passenger compartment can be adjusted and controlled to obtain a comfortable riding experience.

[0134] like Figure 7 As shown, the heat pump wind heat source sub-circuit includes: a compressor 14, an internal condenser 15, a first solenoid valve 16, a second throttling unit 19, an external condenser 21 and a second solenoid valve 22. These components together constitute the heating path of the heat pump wind heat source sub-circuit.

[0135] Specifically, in the heat pump wind heat source sub-circuit, the exhaust port of the compressor 14 is connected to the input port of the inner condenser 15. The compressor 14 compresses the refrigerant gas to increase its temperature and pressure, and transfers heat to the inner condenser 15. The output port of the inner condenser 15 is connected to the first end of the first solenoid valve 16. The inner condenser 15 cools the high-temperature and high-pressure refrigerant gas and converts it into a high-temperature and high-pressure condensate, and then transmits it to the first solenoid valve 16. The second end of the first solenoid valve 16 is connected to the first end of the second throttling unit 19. The first solenoid valve 16 controls the flow of the condensate and guides it to the second throttling unit 19. The second end of the second throttling unit 19 is connected to the input port of the outer condenser 21. The second throttling unit 19 reduces the pressure of the condensate by restricting the flow of the condensate and guides it to the outer condenser 21. The output port of the outer condenser 21 is connected to the first end of the second solenoid valve 22. The outer condenser 21 further cools the condensate and transmits it to the second solenoid valve 22. The second end of the second solenoid valve 22 is connected to the air return port of the compressor 14. The second solenoid valve 22 controls the flow of the condensate so that it flows back to the compressor 14 to complete a complete cycle.

[0136] Through such a design, the heat pump wind heat source sub-circuit can absorb heat from the environment and transfer it to the passenger compartment through compression, condensation, throttling and other processes, thereby realizing the heating function of the vehicle. Through the use of the external condenser 21, the system can cool the condensate more effectively and improve the performance of the heat pump. In addition, through the control of the first solenoid valve 16 and the second solenoid valve 22, the system can adjust the flow and direction of the condensate to achieve precise control of the temperature and heating effect.

[0137] In some embodiments, a third solenoid valve 23 is further provided between the output port of the inner condenser 15 and the output port of the outer condenser 21 . When the passenger compartment is cooled, the third solenoid valve 23 is turned on and the first solenoid valve 16 is turned off.

[0138] In some embodiments, Figure 3 As shown, the air conditioning system further includes an evaporator 24 and a third throttling unit 25. The first end of the third throttling unit 25 is respectively connected to the second end of the first solenoid valve 16, the first end of the first throttling unit 18, and the second end of the external condenser 21. When cooling the passenger compartment, it can be achieved through the evaporator 24.

[0139] In the embodiment, when the passenger compartment is cooled, the refrigerant path is: the third solenoid valve is turned on, the first solenoid valve is turned off, the exhaust port of the compressor is connected to the input port of the inner condenser, the output port of the inner condenser is connected to the first end of the third solenoid valve, the second end of the third solenoid valve is connected to the input end of the outer condenser, the output end of the outer condenser is connected to the first end of the third throttling unit, the second end of the third throttling unit is connected to the first end of the evaporator, and the second end of the evaporator is connected to the return air port of the compressor.

[0140] That is, the compressor transfers the high-temperature and high-pressure refrigerant to the inner condenser 15, where it should be noted that the air flow blowing into the passenger compartment can be adjusted by the air conditioning regulating valve without passing through the inner condenser, so even if the inner condenser 15 releases heat, it will not cause the temperature of the passenger compartment to rise. Then the refrigerant is transferred to the outer condenser 21 through the third solenoid valve 23. The outer condenser 15 releases heat, that is, releases heat to the outside of the vehicle, and converts the high-temperature and high-pressure refrigerant into a low-temperature and high-pressure refrigerant, and then releases pressure through the third throttling unit 25 to reach the evaporator 14. The evaporator 24 is a heat exchanger in the system, which absorbs the heat inside the passenger compartment, thereby realizing the cooling of the passenger compartment. The evaporator 24 is connected to the return air port of the compressor 14 to send the gaseous refrigerant back to the compressor 14 to continue the cycle.

[0141] In some embodiments, the first end of the battery pack water circuit is connected to the fourth interface of the plate heat exchanger 17, and the second end of the battery pack water circuit is connected to the thermal management water pump 27. The thermal management water pump 27 can be a water pump device for circulating and promoting the flow of thermal management water in the battery thermal management water circuit 101. The thermal management water pump 27 can return the thermal management water to the battery pack 26 for circulation through the operation of the water pump. By connecting the thermal management water pump 27 to the third valve port of the first three-way valve 11, the flow direction of the thermal management water can be controlled. Specifically, the thermal management water pump 27 pushes the thermal management water to the first three-way valve 11, and then according to system requirements, the first three-way valve 11 can guide the thermal management water to other components, such as the plate heat exchanger 17 or other heat exchange units.

[0142] Furthermore, if Figure 3 As shown, the input end of the one-way valve 34 is connected to the second valve port of the first three-way valve 11, and the output end of the one-way valve 34 is connected to the second valve port of the second three-way valve 12 and the first end of the heating water pump 30, so that the refrigerant in the electric heating water circuit 102 and the battery thermal management water circuit 101 flows in one direction, that is, the refrigerant enters the electric heating water circuit 102 for heating and then returns to the battery thermal management water circuit 101 to meet the heating requirements of the battery pack 26.

[0143] The controller is connected to the sensor, the first three-way valve 11, the second three-way valve 12 and the four-way valve 13, and is used to control the connectivity of the valve ports of the first three-way valve 11, the second three-way valve 12 and the four-way valve 13 according to the passenger compartment temperature and / or the battery temperature, and to control the electric heating water circuit 102, the battery thermal management water circuit 101, the air-conditioning system and the engine water circuit, so as to realize the switching and joint operation of more thermal management modes and meet the thermal management requirements of the vehicle under more working conditions.

[0144] Figure 8 is a schematic diagram of an air conditioning system cycle of a thermal management system according to an embodiment of the utility model, such as Figure 8As shown, the battery thermal management water circuit 101, the engine water circuit, and the electric heating water circuit 102 circulate separately. When there is no battery heating demand for air conditioning and there is a passenger compartment heating demand, the heating method is the electric heating water circuit 102 heating separately, the heat pump air heat source sub-circuit heating separately, the heat pump water heat source sub-circuit heating separately, or the air conditioning water circuit circulation diagram of the combination of these three heating methods.

[0145] Fig. 9 Schematic diagram of an air conditioning circulation water circuit of a thermal management system according to an embodiment of the utility model, such as Fig. 9 As shown, the battery thermal management water circuit 101 circulates independently, and the engine water circuit is connected to the electric heating water circuit 102. This water circuit is a heating circuit without battery heating demand, but when there is a passenger compartment heating demand, the heating method is the engine water circuit heating alone, or the engine water circuit and the electric heating water circuit 102 are combined for heating, or the engine water circuit, the electric heating water circuit 102 and the heat pump wind heat source sub-circuit are combined for heating, or the engine water circuit, the electric heating water circuit 102 and the heat pump water heat source sub-circuit are combined for heating. Air conditioning water circuit circulation diagram.

[0146] Fig.10 Schematic diagram of an air conditioning circulation water circuit of a thermal management system according to an embodiment of the utility model, such as Fig.10 As shown, the engine water circuit, battery thermal management water circuit 101 are connected with the electric heating water circuit 102. This water circuit is for air conditioning with battery heating demand, and the heating method is heating the engine water circuit alone, or the engine water circuit and battery thermal management water circuit 101 are combined for heating, or the air conditioning water circuit circulation diagram of the engine water circuit, battery thermal management water circuit 101, and heat pump wind heat source sub-circuit.

[0147] In some embodiments, in the hybrid mode, when the passenger compartment has a heating demand and the battery has a heating demand and the engine 31 generates heat to meet the passenger compartment heating demand and the battery heating demand, in order to utilize the heat generated by the engine 31, the system starts the engine 31. In addition, in order to effectively circulate heat and refrigerant, the system simultaneously operates the thermal management water pump 27 and the heating water pump 30. The first valve port of the first three-way valve 11 is connected to the second valve port of the first three-way valve 11, the first valve port of the second three-way valve 12 is connected to the third valve port of the second three-way valve 12, the first valve port of the four-way valve 13 is connected to the fourth valve port of the four-way valve 13, and the second valve port of the four-way valve 13 is connected to the third valve port of the four-way valve 13. Through this connection method, the entire circulating water circuit is connected to the electric heating water circuit 102, the battery thermal management water circuit 101 and the engine water circuit, and the hot water of the engine 31 heats the battery through the battery pack 26, and heats the air-conditioned passenger compartment through the heater core 29, thereby realizing the transfer and distribution of heat.

[0148] In some embodiments, when the heat generated by the engine 31 does not meet the heating needs of the passenger compartment and the battery, in order to supplement the insufficient heat generated by the engine 31, the system also starts the electric heating unit 28 to meet the heating needs of the passenger compartment and the battery. Among them, the electric heating unit 28 can use electrical energy to convert into thermal energy to provide additional heat. In addition, the thermal management water pump 27 is running, the heating water pump 30 is running, and the entire circulating water circuit is connected to the electric heating water circuit 102, the battery thermal management water circuit 101 and the engine water circuit. The hot water from the engine 31 heats the battery through the battery pack 26, and heats the air-conditioned passenger compartment through the heater core 29.

[0149] In some embodiments, when the total heat generated by the engine 31 and the electric heating unit 28 does not meet the heating requirements of the passenger compartment and the battery, in order to further provide heat to meet the heating requirements of the passenger compartment and the battery, the system controls the compressor 14 to start, and the high-temperature and high-pressure gas releases heat after passing through the internal condenser 15. By controlling the compressor 14 to start to start the heat pump wind heat source sub-circuit, the heat pump wind heat source sub-circuit can absorb heat from the environment through compression, condensation, throttling and other processes to provide additional heat.

[0150] In some embodiments, in hybrid mode, when the passenger compartment has a heating demand and the battery has no cooling or heating demand and the engine 31 generates heat to meet the heating demand of the passenger compartment, the system starts the engine 31 and runs the heating water pump 30 to ensure that hot water can circulate to the passenger compartment for heating. The system controls the first valve port of the first three-way valve 11 to be connected with the third valve port of the first three-way valve 11, the first valve port of the second three-way valve 12 to be connected with the second valve port of the second three-way valve 12, the first valve port of the four-way valve 13 to be connected with the fourth valve port, and the second valve port of the four-way valve 13 to be connected with the third valve port. The entire circulating water circuit is an electric heating water circuit 102 connected to the engine water circuit, and the hot water of the engine 31 is heated to the air-conditioned passenger compartment through the heater core 29, thereby ensuring that a comfortable warm environment is provided in the passenger compartment when the vehicle is running.

[0151] In some embodiments, when the heat generated by the engine 31 does not meet the heating demand of the passenger compartment, the system will also start the electric heating unit 28. By converting electrical energy into thermal energy, additional heat is provided for heating the passenger compartment. When the total heat generated by the engine 31 and the electric heating unit 28 does not meet the heating demand of the passenger compartment, the system will control the compressor 14 to start to start the heat pump wind heat source sub-loop.

[0152] In some embodiments, in hybrid mode and the passenger compartment has a heating demand and the battery has a cooling demand and the heat pump water heat source sub-circuit generates heat to meet the heating demand of the passenger compartment, the system controls the compressor 14 to start to increase the temperature and pressure of the refrigerant gas, and the high-temperature and high-pressure gas is converted into a high-temperature and high-pressure condensate after passing through the internal condenser 15, and releases heat. Then, by controlling the compressor 14 to start, the system starts the heat pump water heat source sub-circuit, realizes heat transfer through the circulating water circuit, and transfers the heat to the passenger compartment. When starting the heat pump water heat source sub-circuit, the system will run the thermal management water pump 27 at the same time. The thermal management water pump 27 is responsible for circulating the refrigerant to the engine 31 and the battery for cooling to maintain their normal operating temperature.

[0153] Therefore, in order to achieve the transfer and distribution of thermal energy, the first valve port of the first three-way valve 11 is connected to the third valve port of the first three-way valve 11, the first valve port of the second three-way valve 12 is connected to the second valve port of the second three-way valve 12, the first valve port of the four-way valve 13 is connected to the second valve port of the four-way valve 13, and the third valve port of the four-way valve 13 is connected to the fourth valve port of the four-way valve 13, so as to ensure the correct flow direction of hot water and transfer thermal energy to the passenger compartment.

[0154] In some embodiments, when the heat generated by the heat pump water heat source sub-circuit does not meet the heating needs of the passenger compartment, in order to provide additional heat, the system will start the engine 31 and the heating water pump 30 will run. The entire circulating water circuit is an electrically heated heating water circuit 102 connected to the engine water circuit. The hot water from the engine 31 passes through the heater core 29 to heat the air-conditioned passenger compartment. At the same time, when the compressor 14 is running, the temperature and pressure of the gas can be increased. The high-temperature and high-pressure gas is converted into high-temperature and high-pressure condensate through the internal condenser 15, and releases heat to heat the passenger compartment.

[0155] Therefore, in order to achieve the transfer and distribution of thermal energy, the first valve port of the first three-way valve 11 is connected to the third valve port of the first three-way valve 11, the first valve port of the second three-way valve 12 is connected to the second valve port of the second three-way valve 12, the first valve port of the four-way valve 13 is connected to the fourth valve port of the four-way valve 13, and the second valve port of the four-way valve 13 is connected to the third valve port of the four-way valve 13.

[0156] In some embodiments, when the total heat generated by the heat pump water heat source sub-circuit and the engine 31 does not meet the heating demand of the passenger compartment, the system will also start the electric heating unit 28. The electric heating unit 28 can convert electrical energy into thermal energy to provide additional heat for heating the passenger compartment.

[0157] In some embodiments, in hybrid mode, when there is no heating demand for the passenger compartment and the battery has heating demand and the engine 31 generates heat to meet the battery heating demand, the system starts the engine 31 to generate heat. At the same time, the system starts the heating water pump 30 and the thermal management water pump 27. The entire circulating water circuit is connected to the electric heating water circuit 102, the battery thermal management water circuit 101 and the engine water circuit. The hot water from the engine 31 passes through the battery pack 26 to heat the battery.

[0158] Therefore, in order to achieve the transfer and distribution of thermal energy, the first valve port of the first three-way valve 11 is connected to the second valve port of the first three-way valve 11, the first valve port of the second three-way valve 12 is connected to the third valve port of the second three-way valve 12, the first valve port of the four-way valve 13 is connected to the fourth valve port of the four-way valve 13, and the second valve port of the four-way valve 13 is connected to the third valve port of the four-way valve 13.

[0159] In some embodiments, when the heat generated by the engine 31 does not meet the battery heating requirements, the electric heating unit 28 is also started. At this time, the entire circulating water circuit is connected to the electric heating water circuit 102, the battery thermal management water circuit 101 and the engine water circuit, and the hot water from the engine 31 and the water heated by the electric heating unit 28 pass through the battery pack 26 to heat the battery.

[0160] In some embodiments, in pure electric power mode, when the passenger compartment has heating requirements and the battery has heating requirements, the system starts the electric heating unit 28 and the heating water pump 30, and runs the thermal management water pump 27. The operation of the heating water pump 30 and the thermal management water pump 27 ensures the flow and circulation of hot water. At this time, the entire circulating water circuit is connected to the electric heating water circuit 102 and the battery thermal management water circuit 101. The electric heating unit 28 heats the water through the battery pack 26 to heat the battery, and through the heater core 29 to heat the air-conditioned passenger compartment.

[0161] Therefore, in order to achieve the transfer and distribution of thermal energy, the first valve port of the first three-way valve 11 is connected to the second valve port of the first three-way valve 11, the first valve port of the second three-way valve 12 is connected to the third valve port of the second three-way valve 12, the first valve port of the four-way valve 13 is connected to the second valve port of the four-way valve 13, and the third valve port of the four-way valve 13 is connected to the fourth valve port of the four-way valve 13.

[0162] In some embodiments, when the heat generated by the electric heating unit 28 does not meet the passenger compartment heating requirements and the battery heating requirements and the outdoor temperature is greater than or equal to the preset temperature threshold, the system also controls the compressor 14 to start, and the high-temperature and high-pressure gas releases heat after passing through the internal condenser 15. By controlling the compressor 14 to start to start the heat pump wind heat source sub-circuit, the heat pump wind heat source sub-circuit can absorb heat from the environment through compression, condensation, throttling and other processes to provide additional heat.

[0163] The setting of the preset temperature threshold can be determined according to actual needs and design considerations. The purpose of the preset temperature threshold is to ensure that the heat pump wind heat source sub-circuit is started only when the outdoor temperature is low, so as to make full use of the low-temperature heat in the environment. This is because starting the heat pump system at a lower outdoor temperature can more effectively absorb the low-temperature heat in the environment, thereby improving energy utilization efficiency and reducing energy consumption.

[0164] In some embodiments, when the total heat generated by the electric heating unit 28 and the heat generated by the heat pump wind heat source sub-circuit does not meet the passenger compartment heating requirements and battery heating requirements, the system also starts the engine 31. After the engine 31 is started, the four-way valve 13 runs in a small cycle. When the water temperature of the engine 31 is ≥ the PTC water temperature, it switches to a large cycle. At this time, the circulating water circuit is connected to the electric heating water circuit 102, the battery thermal management water circuit 101, and the engine water circuit. The hot water of the engine 31 and the heated water of the electric heating unit 28 pass through the warm air core 29 and the battery pack 26 to heat the passenger compartment and the battery pack 26.

[0165] Therefore, in order to achieve the transfer and distribution of thermal energy, the first valve port of the first three-way valve 11 is connected to the second valve port of the first three-way valve 11, the first valve port of the second three-way valve 12 is connected to the third valve port of the second three-way valve 12, the first valve port of the four-way valve 13 is connected to the fourth valve port of the four-way valve 13, and the second valve port of the four-way valve 13 is connected to the third valve port of the four-way valve 13.

[0166] In some embodiments, in pure electric power mode, when the passenger compartment has a heating demand and the battery has a heating demand and the heat generated by the electric heating unit 28 does not meet the heating demand of the passenger compartment and the battery heating demand and the outdoor temperature is less than the preset temperature threshold, the system starts the engine 31 for auxiliary heating. At this time, the heating method is the electric heating water circuit 102 and the engine water circuit. After the engine 31 is started, the four-way valve 13 runs in a small cycle, and when the water temperature of the engine 31 is ≥PTC water temperature, it switches to a large cycle. The circulating water circuit is connected to the electric heating water circuit 102, the battery thermal management water circuit 101, and the engine water circuit. The hot water of the engine 31 and the heated water of the electric heating unit 28 pass through the heater core 29 and the battery pack 26 to heat the passenger compartment and the battery pack 26.

[0167] Therefore, in order to achieve the transfer and distribution of thermal energy, the first valve port of the first three-way valve 11 is connected to the second valve port of the first three-way valve 11, the first valve port of the second three-way valve 12 is connected to the third valve port of the second three-way valve 12, the first valve port of the four-way valve 13 is connected to the fourth valve port of the four-way valve 13, and the second valve port of the four-way valve 13 is connected to the third valve port of the four-way valve 13.

By controlling the compressor 14 to start to start the heat pump wind heat source sub-circuit, the heat pump wind heat source sub-circuit can absorb heat from the environment through compression, condensation, throttling and other processes to provide additional heat.

[0169] In some embodiments, when the heat generated by the heat pump wind heat source sub-circuit does not meet the heating demand of the passenger compartment, the system also starts the electric heating unit 28 and the heating water pump 30. At this time, the heating method is the heat pump wind heat source sub-circuit and the electric heating heating water circuit 102. The entire circulating water circuit is a separate circulation of the electric heating heating water circuit 102. The electric heating unit 28 heats the water through the warm air core 29, and the high-temperature and high-pressure gas of the compressor 14 releases heat through the internal condenser 15 to heat the air-conditioned passenger compartment.

[0171] In some embodiments, when the total heat generated by the heat pump wind heat source sub-circuit and the electric heating unit 28 does not meet the heating demand of the passenger compartment, the system also starts the engine 31. At this time, the heating method is a combined heating method of the heat pump wind heat source sub-circuit, the electric heating water circuit 102 and the engine water circuit. After the engine 31 is started, the four-way valve 13 runs in a small cycle. When the water temperature of the engine 31 is ≥PTC water temperature, it switches to a large cycle. The circulating water circuit is the electric heating water circuit 102 connected to the engine water circuit. The hot water of the engine 31 and the electric heating water circuit 102 pass through the warm air core 29 and the high-temperature and high-pressure gas of the compressor 14 through the internal condenser 15 to release heat to the air-conditioned passenger compartment for heating.
