Technical Field
[0001] The present application relates to the field of automotive thermal management technology, and in particular to thermal management systems and vehicles. Background Art
[0002] With the continuous advancement of power systems and the growing market demand, thermal management systems in new energy vehicles have received increasing attention. Thermal management systems can effectively manage and control heat in vehicles to improve performance, efficiency and safety.
[0003] Among them, there are many types of thermal management system architectures for new energy vehicles, and different types of refrigerants often have different solutions. However, in the existing thermal management system architecture, there are very few system architectures that are compatible with multiple refrigerants. Due to the different types of refrigerants used, even models on the same platform are difficult to be compatible in the thermal management system.
[0004] In the existing thermal management system architecture, the heat in the primary circuit can be obtained and transmitted through the secondary circuit, thereby assisting the primary circuit. For the current solution using a secondary circuit, there are usually two situations: one is the pursuit of multi-function and high integration and the use of water valves with more channels (more than ten channels), resulting in problems such as large valve body, large working drive power, and poor compatibility. The other is the use of a large number of low-channel water valves (less than four channels) or more than two five-way water valves and more medium-channel water valves to achieve multi-functions, resulting in a large number of water valves and complex pipelines. Both of the above situations need to improve cost control and performance. Summary of the invention

[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0040] As described in the background technology, in the existing thermal management system architecture, the heat in the primary circuit can be obtained and transmitted through the secondary circuit, thereby assisting the primary circuit. For the current solution using a secondary circuit, there are usually two situations: one is the pursuit of multi-functions and high integration and the use of water valves with more channels (more than ten channels), which leads to problems such as large valve bodies, large working drive power, and poor compatibility. The second is that in order to achieve multi-functions, a large number of low-channel water valves (less than four channels) or more than two five-way water valves and more medium-channel water valves are used, resulting in a large number of water valves and complex pipelines. Both of the above situations need to improve cost control and performance.
[0041] In view of the above technical problems, the first aspect of the embodiment of the present application provides a thermal management system, which has several thermal management modes. Among them, the thermal management system includes a water circuit integration module, a refrigerant integration module and an air conditioning box. Among them, the water circuit integration module includes a valve body assembly, the valve body assembly is connected to the water circuit integration module, and several water circuits are formed in the water circuit integration module by the conduction or shutdown of the valve body assembly, and the refrigerant integration module is heat exchanged through one or more of the several water circuits to achieve one or more of the several thermal management modes. The air conditioning box includes an evaporator or a cooler, the evaporator and the refrigerant integration module form a refrigerant circuit, the cooler and the water circuit integration module form a cooling circuit, and the refrigerant circuit and the cooling circuit are used to realize the air conditioning refrigeration or air conditioning dehumidification mode of different refrigerants. In this way, the thermal management system provided by the embodiment of the present application can integrate the water circuit integration module with a valve assembly, so that the water circuit integration module and the refrigerant integration module cooperate in heat exchange, solving the problem of incompatible refrigerant system architecture and complex water circuit state. The number of water valves and control components is reduced, thereby reducing costs.
[0042] A second aspect of the embodiments of the present application provides a vehicle, which includes a thermal management system.
[0043] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.
[0044] The embodiment of the present application provides a thermal management system and a vehicle. The water circuit integration module is integrated with a valve assembly so that the water circuit integration module and the refrigerant integration module cooperate in heat exchange, solving the problem of incompatibility between the old and new refrigerant system architectures and the complex water circuit state. The number of water valves and control components is reduced, thereby reducing costs. The specific structure of a thermal management system and a vehicle provided by the embodiment of the present application is introduced below in conjunction with the accompanying drawings.
[0045] refer to Figure 1, the embodiment of the present application provides a thermal management system 100 in the first aspect. Among them, the thermal management system 100 can have several thermal management modes to meet the system function requirements. In the embodiment of the present application, the thermal management system 100 may include a water circuit integration module 200 and a refrigerant integration module 300. The water circuit integration module 200 may include a valve body assembly 400. Among them, the valve body assembly 400 may be connected to the water circuit integration module 200. Further, the valve body assembly 400 may include a nine-way water valve 410 and a three-way water valve. In a possible implementation, the number of nine-way water valves 410 may be one, and the number of three-way water valves may be at least one, which is not limited in the embodiment of the present application. In the embodiment of the present application, the nine-way water valve 410 and the three-way water valve may be connected to the water circuit integration module 200, respectively. It can be understood that by opening or closing the valve body assembly 400, several water circuits are formed in the water circuit integrated module 200, and heat is exchanged with the refrigerant integrated module 300 through one or more of the several water circuits, and the secondary circuit is used to assist the primary circuit, thereby realizing one or more of several thermal management modes.
[0046] Continue to refer Figure 1 , based on the above embodiments, in one possible implementation, the refrigerant integrated module 300 may include a compressor 310, a water-cooled condenser 320, a liquid storage tank 330, and a heat exchanger 340. In the embodiment of the present application, the compressor 310, the water-cooled condenser 320, the liquid storage tank 330, and the heat exchanger 340 may be arranged in sequence in one of the refrigerant circuits. A first electronic expansion valve 350 may be provided between the liquid storage tank 330 and the heat exchanger 340, and the flow direction, flow rate, and state of the refrigerant may be controlled by the first electronic expansion valve 350 itself having the function of controlling the on-off of the refrigerant.
[0047] Continue to refer Figure 1 , based on the above embodiment, in one possible implementation, the water-cooled condenser 320 may have a first refrigerant channel 321 and a first water flow channel 322, and the heat exchanger 340 may have a second refrigerant channel 341 and a second water flow channel 342. It can be understood that the first refrigerant channel 321 and the second refrigerant channel 341 are connected to the refrigerant integrated module 300, and the first water flow channel 322 and the second water flow channel 342 are connected to the water channel integrated module 200. The refrigerant passing through the first refrigerant channel 321 can achieve heat exchange with the water passing through the first water flow channel 322. Correspondingly, the refrigerant passing through the second refrigerant channel 341 can achieve heat exchange with the water passing through the second water flow channel 342.
[0048] Continue to refer Figure 1, based on the above embodiment, in one possible implementation, the water circuit integrated module 200 may include a first water pump 210, a second water pump 220 and a third water pump 230. The first water pump 210, the second water pump 220 and the third water pump 230 may all be connected to the nine-way water valve 410, so that the water in the first water pump 210, the second water pump 220 and the third water pump 230 can flow in the water circuit through the nine-way water valve 410. In the embodiment of the present application, the first water pump 210 may be connected to the first water flow channel 322, and the second water pump 220 may be connected to the second water flow channel 342, so as to facilitate the circulation of water, thereby exchanging heat with the refrigerant integrated module 300.
[0049] Continue to refer Figure 1 On the basis of the above embodiment, in one possible implementation, the nine-way water valve 410 may include a first port 411, a second port 412, a third port 413, a fourth port 414, a fifth port 415, a sixth port 416, a seventh port 417, an eighth port 418 and a ninth port 419. It is understandable that water can flow through the first port 411, the second port 412, the third port 413, the fourth port 414, the fifth port 415, the sixth port 416, the seventh port 417, the eighth port 418 and the ninth port 419 and switch or mix different ports to realize different water conduction loops.
[0050] In a possible implementation, the number of three-way water valves is two for example. Figure 1As shown, the three-way water valve may include a first three-way water valve 420 and a second three-way water valve 430, and the first three-way water valve 420 and the second three-way water valve 430 may each include at least a first valve port 440, a second valve port 450 and a third valve port 460. It is understandable that different valve ports of the two three-way water valves may be connected to different ports of the nine-way water valve 410 to achieve different water circuits. In the embodiment of the present application, the first valve port 440 of the first three-way water valve 420 may be connected to the sixth port 416 of the nine-way water valve 410, the second valve port 450 of the first three-way water valve 420 may be connected to the fourth port 414 of the nine-way water valve 410, and the third valve port 460 of the first three-way water valve 420 may be connected to the inlet end of the third water pump 230. In addition, the first valve port 440 of the second three-way water valve 430 can be connected to the outlet of the heat exchanger 340, the second valve port 450 of the first three-way water valve 420 can be connected to the outlet of the air conditioning box 700, and the third valve port 460 of the first three-way water valve 420 can be connected to the fifth port 415 of the nine-way water valve 410. By arranging the nine-way water valve 410 and the three-way water valve in the water channel integrated module 200, the functional control components of the water channel conduction loop are integrated, which solves the problem that the number of control components must be large if there are many functions, or the appearance of the multi-channel water valve is bulky.
[0051] Continue to refer Figure 1 On the basis of the above embodiment, the thermal management system 100 may further include: a power battery 500, a motor electronic control component 600, a radiator 610 and an air conditioning box 700. Among them, the inlet end of the power battery 500 can be connected to the outlet end of the third water pump 230, and the outlet end of the power battery 500 can be connected to the fourth port 414 of the nine-way water valve 410. In a possible implementation, one end of the motor electronic control component 600 can be connected to one end of the radiator 610, and the other end of the motor electronic control component 600 can be connected to the first port 411 of the nine-way water valve 410. In addition, the other end of the radiator 610 can be connected to the ninth port 419 of the nine-way water valve 410. One end of the air conditioning box 700 can be connected to the eighth port 418 of the nine-way water valve 410, and the other end of the air conditioning box 700 can cooperate with the refrigerant integrated module 300.
[0052] In a possible implementation, the number of the air conditioning box 700 may be one or more, and the number of the air conditioning box 700 may be selected according to different scenarios, and the embodiment of the present application does not limit this. In the embodiment of the present application, the number of the air conditioning box 700 is taken as one for example.
[0053] refer to Figure 2In a possible implementation, when the refrigerant used is R134a or R1234yf, it can be matched with the evaporator 720, and the evaporator 720 can form a refrigerant circuit with the refrigerant integrated module 300. At this time, the thermal management system 100 can be a partial secondary circuit system. Further, the air conditioner 700 may include: a blower 710, an evaporator 720 and a heating element 730. Among them, the blower 710 can be located on one side of the air conditioner 700, and the blower 710 can be arranged toward the evaporator 720 and the heating element 730. The inlet end of the evaporator 720 can be provided with a second electronic expansion valve 360, and the outlet end of the evaporator 720 can be provided with a first one-way valve 370, and the flow direction, flow rate, and state of the refrigerant can be controlled by the second electronic expansion valve 360 and the first one-way valve 370 themselves. It is understandable that the second electronic expansion valve 360 and the first one-way valve 370 can be integrated into the refrigerant integrated module 300. The inlet end of the heating element 730 can be connected to the first water flow channel 322, and the outlet end of the heating element 730 can be connected to the eighth port 418 of the nine-way water valve 410. It is understandable that the blower 710 is usually used to promote air flow. The evaporator 720 can make the liquid refrigerant absorb heat and evaporate into a gaseous refrigerant, absorb heat in the air through the evaporation of the refrigerant, thereby reducing the temperature of the air, and usually has a refrigeration and dehumidification effect. The heating element 730 can heat the water flow during the flow of water.
[0054] Continue to refer Figure 2 On the basis of the above embodiments, in one possible implementation, in the refrigerant integrated module 300, the refrigerant can flow through the compressor 310, the first refrigerant channel 321 of the water-cooled condenser 320 and the liquid storage tank 330 in sequence, and then flow through the evaporator 720 through the second electronic expansion valve 360, and finally the evaporator 720 is connected to the compressor 310 through the first one-way valve 370 to form a refrigerant conduction circuit.
[0055] In the water path integrated module 200, the water in the first water pump 210 can flow in sequence through the first water flow channel 322 of the water-cooled condenser 320 and the heating element 730 in the air-conditioning box 700, and then flow to the eighth port 418 of the nine-way water valve 410, connecting the eighth port 418 and the seventh port 417, and allowing the water to flow through the radiator 610 and the motor electronic control component 600 in sequence through the seventh port 417, and then flow to the first port 411 of the nine-way water valve 410, connecting the first port 411 and the second port 412, and allowing the water to flow back to the first water pump 210 through the second port 412 to realize the air-conditioning refrigeration or air-conditioning dehumidification mode in the thermal management mode.
[0056] It can be understood that in the air conditioning refrigeration or air conditioning dehumidification mode, the high-temperature and high-pressure gaseous refrigerant flows out from the outlet of the compressor 310, and then enters the first refrigerant channel 321 of the water-cooled condenser 320, and realizes heat exchange with the first water flow channel 322 of the water-cooled condenser 320. The refrigerant in the first refrigerant channel 321 is condensed into a high-temperature and high-pressure liquid refrigerant by releasing heat. At least part of the high-temperature and high-pressure liquid refrigerant is stored in the liquid storage tank 330, and the other part of the high-temperature and high-pressure liquid refrigerant is throttled and reduced in pressure through the second electronic expansion valve 360, so that the low-temperature and low-pressure liquid refrigerant enters the evaporator 720. In the evaporator 720, the low-temperature and low-pressure liquid refrigerant absorbs heat and evaporates to form a gaseous refrigerant and cools the passenger compartment. After fully evaporating, the low-temperature and low-pressure gaseous refrigerant enters the compressor 310 through the first one-way valve 370, so that the refrigerant enters the next cycle to realize air conditioning refrigeration or air conditioning dehumidification.
[0057] Accordingly, the temperature of the water passing through the first water flow channel 322 of the water-cooled condenser 320 is lower than the temperature of the refrigerant in the first refrigerant channel 321, thereby achieving heat exchange between the refrigerant conduction circuit and the water conduction circuit. The water flows to the heating element 730 in the air conditioning box 700 for heating, and then flows to the radiator 610 through the nine-way water valve 410, thereby exchanging heat with the external environment and reducing the water temperature, and then flows to the motor electronic control component 600 and dissipates heat for the motor electronic control component 600, and then flows back to the first water pump 210 through the nine-way water valve 410 to complete the water circuit circulation.
[0058] Continue to refer Figure 2 , based on the above embodiments, in one possible implementation, in the refrigerant integrated module 300, the refrigerant can flow through the compressor 310, the first refrigerant channel 321 of the water-cooled condenser 320 and the liquid storage tank 330 in sequence, and then flow through the second refrigerant channel 341 of the heat exchanger 340 through the first electronic expansion valve 350, and the outlet of the second refrigerant channel 341 can be connected to the inlet of the compressor 310 to form a refrigerant conduction circuit.
[0059] In the water channel integrated module 200, water from the first water pump 210 can flow in sequence through the first water flow channel 322 of the water-cooled condenser 320 and the heating element 730 in the air-conditioning box 700, and then flow to the eighth port 418 of the nine-way water valve 410, connecting the eighth port 418 and the second port 412, and allowing the water to flow back to the first water pump 210 through the second port 412.
[0060] In addition, water from the second water pump 220 can flow through the second water flow channel 342 of the heat exchanger 340, and then flow to the fifth port 415 of the nine-way water valve 410, connecting the fifth port 415 and the seventh port 417, and allowing the water to flow through the radiator 610 and the motor electronic control component 600 in sequence through the seventh port 417, and then flow to the first port 411 of the nine-way water valve 410, connecting the first port 411 and the third port 413, and allowing the water to flow back to the second water pump 220 through the third port 413, so as to realize the air conditioning heating mode in the thermal management mode.
[0061] It can be understood that in the air conditioning heating mode, the high-temperature and high-pressure gaseous refrigerant flows out from the outlet of the compressor 310, and then enters the first refrigerant channel 321 of the water-cooled condenser 320, and exchanges heat with the first water flow channel 322 of the water-cooled condenser 320. The refrigerant in the first refrigerant channel 321 is condensed into a high-temperature and high-pressure liquid refrigerant by releasing heat. At least part of the high-temperature and high-pressure liquid refrigerant is stored in the liquid storage tank 330, and the other part of the high-temperature and high-pressure liquid refrigerant is throttled and reduced in pressure through the first electronic expansion valve 350, so that the low-temperature and low-pressure liquid refrigerant enters the second refrigerant channel 341 of the heat exchanger 340, and exchanges heat with the second water flow channel 342 of the heat exchanger 340. In the heat exchanger 340, the low-temperature and low-pressure liquid refrigerant absorbs heat and evaporates to form a gaseous refrigerant, and then enters the compressor 310, so that the refrigerant enters the next cycle.
[0062] Accordingly, the temperature of the water passing through the first water flow channel 322 of the water-cooled condenser 320 is lower than the temperature of the refrigerant in the first refrigerant channel 321, thereby achieving heat exchange between the refrigerant conduction circuit and the water conduction circuit. The water flows to the heating element 730 in the air conditioning box 700 to achieve heating, thereby achieving the heating function of the passenger compartment, and then flows back to the first water pump 210 through the nine-way water valve 410, completing a circulation of the water conduction circuit;
[0063] Furthermore, the temperature of the water passing through the second water flow channel 342 of the heat exchanger 340 is greater than the temperature of the refrigerant in the second refrigerant channel 341, thereby achieving heat exchange between the refrigerant conduction circuit and the water conduction circuit. The water flows to the radiator 610 through the nine-way water valve 410, thereby exchanging heat with the external environment and reducing the water temperature, and then flows to the motor electronic control component 600 and dissipates the heat of the motor electronic control component 600, and then flows back to the second water pump 220 through the nine-way water valve 410, completing a circulation of the water conduction circuit to achieve air conditioning heating.
[0064] Continue to refer Figure 2, based on the above embodiments, in one possible implementation, in the refrigerant integrated module 300, the refrigerant can flow through the compressor 310, the first refrigerant channel 321 of the water-cooled condenser 320 and the liquid storage tank 330 in sequence, and then flow through the second refrigerant channel 341 of the heat exchanger 340 through the first electronic expansion valve 350, and the outlet of the second refrigerant channel 341 can be connected to the inlet of the compressor 310 to form a refrigerant conduction circuit.

[0067] It can be understood that in the battery cooling mode, the high-temperature and high-pressure gaseous refrigerant flows out from the outlet of the compressor 310, and then enters the first refrigerant channel 321 of the water-cooled condenser 320, and exchanges heat with the first water flow channel 322 of the water-cooled condenser 320. The refrigerant in the first refrigerant channel 321 is condensed into a high-temperature and high-pressure liquid refrigerant by releasing heat. At least part of the high-temperature and high-pressure liquid refrigerant is stored in the liquid storage tank 330, and another part of the high-temperature and high-pressure liquid refrigerant is throttled and reduced in pressure through the first electronic expansion valve 350, so that the low-temperature and low-pressure liquid refrigerant enters the second refrigerant channel 341 of the heat exchanger 340, and exchanges heat with the second water flow channel 342 of the heat exchanger 340. In the heat exchanger 340, the low-temperature and low-pressure liquid refrigerant absorbs heat and evaporates to form a gaseous refrigerant, and then enters the compressor 310, so that the refrigerant enters the next cycle.

[0092] refer to Figure 3 In another possible embodiment, when the refrigerant used is R290, it can be matched with the cooler 740, and the cooler 740 can form a cooling circuit with the water channel integrated module 200. At this time, the thermal management system 100 can be a complete secondary circuit system. Further, the air conditioner 700 may include: a blower 710, a cooler 740 and a heater 730. Among them, the blower 710 can be located on one side of the air conditioner 700, and the blower 710 can be arranged toward the cooler 740 and the heater 730. The inlet end of the cooler 740 can be connected to the second valve port 450 of the second three-way water valve 430, and the outlet end of the cooler 740 can be connected to the third port 413 of the nine-way water valve 410. The inlet end of the heater 730 can be connected to the first water flow channel 322, and the outlet end of the heater 730 can be connected to the eighth port 418 of the nine-way water valve 410.
[0093] It is understandable that the refrigerant used in the complete secondary circuit system provided in the embodiment of the present application can also be other refrigerants such as R134a, R1234yf, etc., and the embodiment of the present application is not limited here.
[0094] Continue to refer Figure 3 , based on the above embodiments, in one possible implementation, in the refrigerant integrated module 300, the refrigerant can flow through the compressor 310, the first refrigerant channel 321 of the water-cooled condenser 320 and the liquid storage tank 330 in sequence, and then flow through the second refrigerant channel 341 of the heat exchanger 340 through the first electronic expansion valve 350, and the outlet of the second refrigerant channel 341 can be connected to the inlet of the compressor 310 to form a refrigerant conduction circuit.
[0095] In the water circuit integrated module 200 , the flow direction of water of the first water pump 210 is the same as the flow direction of water of the first water pump 210 in the air conditioning cooling or air conditioning dehumidification mode in the partial secondary loop system.
[0096] In addition, water from the second water pump 220 can flow through the second water flow channel 342 of the heat exchanger 340, and then flow to the first valve port 440 of the second three-way water valve 430, flow out of the second valve port 450 of the second three-way water valve 430, so that the water flows to the cooler 740, and then the water flows back to the second water pump 220 to realize the air conditioning refrigeration or air conditioning dehumidification mode in the thermal management mode.

[0100] Continue to refer Figure 3 , based on the above embodiments, in one possible implementation manner, in the refrigerant integration module 300, the flow direction of the refrigerant is the same as the flow direction of the refrigerant in the air conditioning heating mode in the partial secondary circuit system.
[0101] In the water circuit integrated module 200 , the flow direction of water of the first water pump 210 is the same as the flow direction of water of the first water pump 210 in the air conditioning heating mode of the partial secondary loop system.
[0102] In addition, water from the second water pump 220 can flow through the second water flow channel 342 of the heat exchanger 340, and flow to the first valve port 440 of the second three-way water valve 430, flow out of the third valve port 460 of the second three-way water valve 430, and then flow to the fifth port 415 of the nine-way water valve 410, connecting the fifth port 415 and the seventh port 417, and allowing the water to flow through the radiator 610 and the motor electronic control component 600 in sequence through the seventh port 417, and then flow to the first port 411 of the nine-way water valve 410, connecting the first port 411 and the third port 413, and allowing the water to flow back to the second water pump 220 through the third port 413 to realize the air conditioning heating mode in the thermal management mode.
[0103] It can be understood that in the air conditioning heating mode, the refrigerant circuit in the complete secondary circuit system is the same as the refrigerant circuit in the partial secondary circuit system.
[0104] Accordingly, in the air-conditioning heating mode, the water circuit of the first water pump 210 in the complete secondary circuit system is the same as the water circuit of the first water pump 210 in the partial secondary circuit system.
[0105] Furthermore, the temperature of the water passing through the second water flow channel 342 of the heat exchanger 340 is greater than the temperature of the refrigerant in the second refrigerant channel 341, thereby achieving heat exchange between the refrigerant conduction circuit and the water conduction circuit. The water flows through the second three-way water valve 430 and the nine-way water valve 410 in sequence and flows to the radiator 610, thereby exchanging heat with the external environment and reducing the water temperature, and then flows to the motor electronic control component 600 and dissipates heat for the motor electronic control component 600, and then flows back to the second water pump 220 through the nine-way water valve 410, completing a circulation of the water conduction circuit and achieving air conditioning heating.
[0106] Continue to refer Figure 3 , based on the above embodiment, in one possible implementation, the air conditioner 700 may further include a damper (not shown in the figure). The damper may be located between the cooler 740 and the heater 730 to separate the cooler 740 and the heater 730. In the refrigerant integrated module 300, the flow direction of the refrigerant is the same as the flow direction of the refrigerant in the battery cooling mode in the partial secondary circuit system.
[0107] In the water circuit integrated module 200 , the flow direction of water of the first water pump 210 is the same as the flow direction of water of the first water pump 210 in the battery cooling mode in the partial secondary circuit system.
[0108] In addition, water from the second water pump 220 can flow through the second water flow channel 342 of the heat exchanger 340, and flow to the first valve port 440 of the second three-way water valve 430, flow out of the third valve port 460 of the second three-way water valve 430, and then flow to the fifth port 415 of the nine-way water valve 410, connecting the fifth port 415 and the sixth port 416, and allowing the water to flow to the first valve port 440 of the first three-way water valve 420 through the sixth port 416, and flow out of the third valve port 460 of the first three-way water valve 420. The water flows through the third water pump 230 and the power battery 500 in turn, and then flows to the fourth port 414 of the nine-way water valve 410, connecting the fourth port 414 and the third port 413, and allowing the water to flow back to the second water pump 220 through the third port 413 to realize the battery cooling mode in the thermal management mode.
[0109] It can be understood that in the battery cooling mode, the refrigerant circuit in the full secondary circuit system is the same as the refrigerant circuit in the partial secondary circuit system.
[0110] Accordingly, in the battery cooling mode, the water circuit of the first water pump 210 in the full secondary circuit system is the same as the water circuit of the first water pump 210 in the partial secondary circuit system.
[0111] Furthermore, the temperature of the water passing through the second water flow channel 342 of the heat exchanger 340 is greater than the temperature of the refrigerant in the second refrigerant channel 341, thereby achieving heat exchange between the refrigerant conduction circuit and the water conduction circuit, thereby reducing the water temperature. The water flows through the second three-way water valve 430, the nine-way water valve 410 and the first three-way water valve 420 in sequence, and then flows to the third water pump 230 and the power battery 500, thereby cooling the power battery 500, and then flows back to the second water pump 220 through the nine-way water valve 410, completing a circulation of the water conduction circuit to achieve battery cooling.
[0112] Based on the above embodiments, it can be understood that when the damper is in a closed state, the operation mode of the thermal management system 100 is a battery cooling mode.
[0113] Continue to refer Figure 3 , based on the above embodiments, in one possible implementation manner, in the refrigerant integrated module 300, the flow direction of the refrigerant is the same as the flow direction of the refrigerant in the battery heating mode in the partial secondary circuit system.
[0114] In the water circuit integrated module 200 , the flow direction of water of the first water pump 210 is the same as the flow direction of water of the first water pump 210 in the battery heating mode in the partial secondary circuit system.
[0115] Additionally, the flow direction of water of the second water pump 220 is the same as the flow direction of water of the second water pump in the battery heating mode in the partial secondary circuit system to implement the battery heating mode in the thermal management mode.
[0116] It can be understood that in the battery heating mode, the refrigerant circuit, the water circuit of the first water pump 210 and the water circuit of the second water pump 220 in the complete secondary circuit system are the same as the refrigerant circuit, the water circuit of the first water pump 210 and the water circuit of the second water pump 220 in the partial secondary circuit system, thereby achieving battery heating.
[0117] Based on the above embodiments, it can be understood that when the damper is in a closed state, the operation mode of the thermal management system 100 is a battery heating mode.
[0118] Continue to refer Figure 3 On the basis of the above embodiment, in one possible implementation, the refrigerant may flow through the compressor 310, the first refrigerant channel 321 of the water-cooled condenser 320, and the liquid storage tank 330 in sequence, and then flow through the second refrigerant channel 341 of the heat exchanger 340 through the first electronic expansion valve 350, and the outlet of the second refrigerant channel 341 may be connected to the inlet of the compressor 310 to form a refrigerant conduction loop. Then, the two water conduction loops of the battery cooling mode in the thermal management mode are matched with the refrigerant integrated module 300 to realize the two modes of air conditioning refrigeration / dehumidification and battery cooling.
[0119] In the second water pump 220, part of the water flowing through the first valve port 440 of the second three-way water valve 430 flows out from the second valve port 450 of the second three-way water valve 430, and then flows to the cooler 740 for air conditioning refrigeration / dehumidification. Correspondingly, another part of the water flowing through the first valve port 440 of the second three-way water valve 430 flows out from the third valve port 460 of the second three-way water valve 430, and then flows to the power battery 500 for battery cooling.
[0120] It can be understood that in the two modes of air conditioning cooling / dehumidification and battery cooling, the high-temperature and high-pressure gaseous refrigerant flows out from the outlet of the compressor 310, and then enters the first refrigerant channel 321 of the water-cooled condenser 320, and exchanges heat with the first water flow channel 322 of the water-cooled condenser 320. The refrigerant in the first refrigerant channel 321 is condensed into a high-temperature and high-pressure liquid refrigerant by releasing heat. At least part of the high-temperature and high-pressure liquid refrigerant is stored in the liquid storage tank 330, and the other part of the high-temperature and high-pressure liquid refrigerant is throttled and reduced in pressure through the first electronic expansion valve 350, so that the low-temperature and low-pressure liquid refrigerant enters the second refrigerant channel 341 of the heat exchanger 340, and exchanges heat with the second water flow channel 342 of the heat exchanger 340. In the heat exchanger 340, the low-temperature and low-pressure liquid refrigerant absorbs heat and evaporates to form a gaseous refrigerant, and then enters the compressor 310, so that the refrigerant enters the next cycle.
[0121] Accordingly, in both the air conditioning cooling / dehumidification mode and the battery cooling mode, the water circuit of the first water pump 210 in the complete secondary circuit system is the same as the water circuit of the first water pump 210 in the partial secondary circuit system.
[0122] Further, the temperature of the water passing through the second water flow channel 342 of the heat exchanger 340 is greater than the temperature of the refrigerant in the second refrigerant channel 341, thereby realizing heat exchange between the refrigerant conduction circuit and the water conduction circuit, thereby reducing the water temperature. A part of the water passing through the second three-way water valve 430 flows to the cooler 740 in the air conditioning box 700, thereby cooling the passenger compartment, and then flows back to the second water pump 220, completing a circulation of a water conduction circuit. Another part of the water flowing through the second three-way water valve 430 circulates in turn through the nine-way water valve 410 and the first three-way water valve 420, and then flows to the third water pump 230 and the power battery 500, thereby cooling the power battery 500, and then flows back to the second water pump 220 through the nine-way water valve 410, completing a circulation of a water conduction circuit. Cooperate with the refrigerant integrated module 300 to realize air conditioning refrigeration / dehumidification and battery cooling.
[0123] Continue to refer Figure 3 On the basis of the above embodiment, in one possible implementation, in the refrigerant integrated module 300, the flow direction of the refrigerant is the same as the flow direction of the refrigerant in the air conditioning heating and battery cooling modes in the partial secondary circuit system. Then, the two water circuits of the battery cooling mode in the thermal management mode are matched with the refrigerant integrated module 300 to realize the air conditioning heating and battery cooling modes.
[0124] It can be understood that in both the air conditioning heating and battery cooling modes, the refrigerant circuit in the complete secondary circuit system is the same as the refrigerant circuit in the partial secondary circuit system.
[0125] Accordingly, in both the air-conditioning heating mode and the battery cooling mode, the water circuit of the first water pump 210 in the complete secondary circuit system is the same as the water circuit of the first water pump 210 in the partial secondary circuit system.

Cooperate with the refrigerant integrated module 300 to achieve air conditioning heating and battery cooling.
[0127] Based on the above embodiments, it can be understood that when the damper is in an open state, the operation mode of the thermal management system 100 is the air conditioning heating and battery cooling mode.
[0128] Continue to refer Figure 3 On the basis of the above embodiments, in a possible implementation, in the refrigerant integrated module 300, the refrigerant can flow through the compressor 310, the first refrigerant channel 321 of the water-cooled condenser 320 and the liquid storage tank 330 in sequence, and then flow through the second refrigerant channel 341 of the heat exchanger 340 through the first electronic expansion valve 350, and the outlet of the second refrigerant channel 341 can be connected to the inlet of the compressor 310 to form a refrigerant conduction circuit. Then, the two water conduction circuits of the battery heating mode in the thermal management mode are matched with the refrigerant integrated module 300 to realize the two modes of air conditioning cooling / dehumidification and battery heating.
[0129] In the second water pump 220, part of the water flowing through the first valve port 440 of the second three-way water valve 430 flows out from the second valve port 450 of the second three-way water valve 430, and then flows to the cooler 740 for air conditioning refrigeration / dehumidification. Correspondingly, another part of the water flowing through the first valve port 440 of the second three-way water valve 430 flows out from the third valve port 460 of the second three-way water valve 430, and then flows to the motor electronic control component 600, for heat storage of the motor electronic control component 600.
[0130] It can be understood that in the two modes of air conditioning cooling / dehumidification and battery heating, the high-temperature and high-pressure gaseous refrigerant flows out from the outlet of the compressor 310, and then enters the first refrigerant channel 321 of the water-cooled condenser 320, and exchanges heat with the first water flow channel 322 of the water-cooled condenser 320. The refrigerant in the first refrigerant channel 321 is condensed into a high-temperature and high-pressure liquid refrigerant by releasing heat. At least part of the high-temperature and high-pressure liquid refrigerant is stored in the liquid storage tank 330, and the other part of the high-temperature and high-pressure liquid refrigerant is throttled and reduced in pressure through the first electronic expansion valve 350, so that the low-temperature and low-pressure liquid refrigerant enters the second refrigerant channel 341 of the heat exchanger 340, and exchanges heat with the second water flow channel 342 of the heat exchanger 340.

[0131] Accordingly, in both the air conditioning cooling / dehumidification mode and the battery heating mode, the water circuit of the first water pump 210 in the complete secondary circuit system is the same as the water circuit of the first water pump 210 in the partial secondary circuit system.
[0132] Furthermore, the temperature of the water in the second water flow channel 342 of the heat exchanger 340 is greater than the temperature of the refrigerant in the second refrigerant channel 341, thereby realizing heat exchange between the refrigerant conduction circuit and the water conduction circuit, thereby reducing the water temperature. A part of the water passing through the second three-way water valve 430 flows to the cooler 740 in the air conditioning box 700, thereby cooling the passenger compartment, and then flows back to the second water pump 220, completing a circulation of a water conduction circuit. Another part of the water passing through the second three-way water valve 430 flows through the nine-way water valve 410 and flows to the radiator 610, thereby exchanging heat with the external environment and further reducing the water temperature, and then flows to the motor electronic control component 600 and dissipates heat from the motor electronic control component 600, and then flows back to the second water pump 220 through the nine-way water valve 410, completing a circulation of a water conduction circuit, and cooperating with the refrigerant integrated module 300 to achieve air conditioning refrigeration / dehumidification and battery heating.
[0133] Continue to refer Figure 3 On the basis of the above embodiment, in one possible implementation, in the refrigerant integrated module 300, the flow direction of the refrigerant is the same as the flow direction of the refrigerant in the air conditioning heating and battery heating modes in the partial secondary circuit system. Then, the two water conduction circuits of the battery heating mode in the thermal management mode are matched with the refrigerant integrated module 300 to realize the air conditioning heating and battery heating modes.
[0134] It can be understood that in the two modes of air conditioning heating and battery heating, the refrigerant circuit, the water circuit of the first water pump 210 and the water circuit of the second water pump 220 in the complete secondary circuit system are the same as the refrigerant circuit, the water circuit of the first water pump 210 and the water circuit of the second water pump 220 in the partial secondary circuit system to achieve air conditioning heating and battery heating.
[0135] Based on the above embodiments, it can be understood that when the damper is in an open state, the operation mode of the thermal management system 100 is the air conditioning heating and battery heating mode.
[0136] Continue to refer Figure 3 On the basis of the above embodiment, in the two modes of air conditioning cooling / dehumidification and battery cooling, when the water temperatures required by the air conditioning box 700 and the power battery 500 are inconsistent, the temperature and flow rate of the water flow can be adjusted by the first three-way water valve 420, so that the water flowing out of the second water pump 220 is mixed with the water flowing through the power battery 500 from the third water pump 230 after passing through the first three-way water valve 420.
[0137] It is understandable that in a complete secondary loop system, for example, the required temperature range of the cooler 740 in the air-conditioning box 700 may be 0-5°C, while the required temperature range of the power battery 500 may be 19-25°C, and the first three-way water valve 420 is required to adjust the water flowing out of the second water pump 220 so that the water flow temperature satisfies the air-conditioning box 700 and the power battery 500 respectively. Among them, the water flowing through the cooler 740 flows to the fifth port 415 of the nine-way water valve 410 after passing through the second three-way water valve 430, connects the fifth port 415 and the sixth port 416, flows to the first three-way water valve 420 through the sixth port 416, and adjusts the temperature and flow of this part of the water flow through the first three-way water valve 420. Accordingly, the water flowing out of the third water pump 230 always circulates and cools the power battery 500. In this way, the water flowing out of the third valve port 460 of the first three-way water valve 420 and the water flowing through the power battery 500 from the third water pump 230 are mixed, so that the temperature of the mixed water flow meets the required temperature of the power battery 500, and then the mixed water flows to the third water pump 230 and the power battery 500 in turn, and then returns to the second water pump 220 through the nine-way water valve 410.
[0138] On the basis of the above-mentioned embodiment, the temperature and flow rate of the water flow are adjusted by the first three-way water valve 420, which not only ensures the cooling function of the air-conditioning box 700 and the power battery 500, but also saves the number of valve bodies, thereby achieving the purpose of reducing the cost of the thermal management system 100.
[0139] Continue to refer Figure 1On the basis of the above embodiment, in at least part of the thermal management mode, if the motor electronic control component 600 does not need to dissipate heat, the heat exchange path of the water-cooled condenser 320 can be: the water of the first water pump 210 can flow through the first water flow channel 322 of the water-cooled condenser 320 and the heating element 730 in the air conditioning box 700 in sequence, and then flow to the eighth port 418 of the nine-way water valve 410, connect the eighth port 418 with the seventh port 417, and make the water flow to the radiator 610 through the seventh port 417, and then flow to the ninth port 419 of the nine-way water valve 410, connect the ninth port 419 with the second port 412, and make the water flow back to the first water pump 210 through the second port 412. Among them, the thermal management mode under this path can include air conditioning cooling / dehumidification mode, battery cooling mode, and air conditioning cooling / dehumidification and battery cooling modes.
[0140] Continue to refer Figure 1 On the basis of the above embodiment, in at least part of the thermal management mode, if energy is not drawn from the environment but only the residual heat or heat storage of the motor electronic control component 600 is used, the heat exchange path of the heat exchanger 340 may be: the water of the second water pump 220 may flow through the second water flow channel 342 of the heat exchanger 340, and then flow to the first valve port 440 of the second three-way water valve 430, flow out of the third valve port 460 of the second three-way water valve 430, and then flow to the fifth port 415 of the nine-way water valve 410, connect the fifth port 415 with the ninth port 419, and make the water flow to the motor electronic control component 600 through the ninth port 419, and then flow to the first port 411 of the nine-way water valve 410, connect the first port 411 with the third port 413, and make the water flow back to the second water pump 220 through the third port 413. The thermal management mode under this path may include two modes: air conditioning cooling / dehumidification mode and battery heating mode.
[0141] Continue to refer Figure 1 On the basis of the above embodiment, in at least part of the thermal management mode, if the motor electronic control component 600 and the radiator 610 do not need to exchange heat with the outside, the heat exchange path of the water-cooled condenser 320 can be: the water of the first water pump 210 can flow through the first water flow channel 322 of the water-cooled condenser 320 and the heating element 730 in the air conditioning box 700 in sequence, and then flow to the eighth port 418 of the nine-way water valve 410, connect the eighth port 418 with the seventh port 417, and make the water flow to the radiator 610 through the seventh port 417, and then flow to the ninth port 419 of the nine-way water valve 410, connect the ninth port 419 with the second port 412, and make the water flow back to the first water pump 210 through the second port 412. Among them, the thermal management mode under this path can include two modes: air conditioning heating and battery cooling.
[0142] Continue to refer Figure 1On the basis of the above embodiment, in at least part of the thermal management mode, if the radiator 610 does not need to exchange heat with the outside, the heat exchange path of the heat exchanger 340 can be: the water of the second water pump 220 can flow through the second water flow channel 342 of the heat exchanger 340, and then flow to the first valve port 440 of the second three-way water valve 430, flow out of the third valve port 460 of the second three-way water valve 430, and then flow to the fifth port 415 of the nine-way water valve 410, connect the fifth port 415 with the ninth port 419, and make the water flow to the motor electronic control component 600 through the ninth port 419, and then flow to the first port 411 of the nine-way water valve 410, connect the first port 411 with the third port 413, and make the water flow back to the second water pump 220 through the third port 413. Among them, the thermal management mode under this path can include air conditioning heating mode, battery heating mode, and air conditioning heating and battery heating modes.
[0143] Continue to refer Figure 1 , based on the above embodiments, in a possible implementation, in the water circuit integrated module 200, the water of the first water pump 210 can flow through the first water flow channel 322 of the water-cooled condenser 320 and the heating element 730 in the air conditioning box 700 in sequence, and then flow to the eighth port 418 of the nine-way water valve 410, connect the eighth port 418 with the seventh port 417, and make the water flow through the radiator 610 and the motor electronic control component 600 in sequence through the seventh port 417, and then flow to the first port 411 of the nine-way water valve 410, connect the first port 411 with the second port 412, and make the water flow back to the first water pump 210 through the second port 412, so as to realize the driving defrosting mode in the thermal management mode or the heat dissipation mode of the motor electronic control component 600. At this time, the refrigerant integrated module 300 does not need to be operated.
[0144] Continue to refer Figure 1 On the basis of the above embodiment, in another possible implementation, in the water circuit integrated module 200, the water of the second water pump 220 can flow through the second water flow channel 342 of the heat exchanger 340, and flow to the first valve port 440 of the second three-way water valve 430, flow out of the third valve port 460 of the second three-way water valve 430, and then flow to the fifth port 415 of the nine-way water valve 410, connect the fifth port 415 with the seventh port 417, and make the water flow through the radiator 610 and the motor electronic control component 600 in sequence through the seventh port 417, and then flow to the first port 411 of the nine-way water valve 410, connect the first port 411 with the third port 413, and make the water flow back to the second water pump 220 through the third port 413, so as to realize the driving defrosting mode in the thermal management mode or the heat dissipation mode of the motor electronic control component 600. At this time, the refrigerant integrated module 300 does not need to be operated.
[0145] Continue to refer Figure 1 On the basis of the above embodiments, in a possible implementation, in the water circuit integrated module 200, the water of the third water pump 230 can flow through the power battery 500, and then flow to the fourth port 414 of the nine-way water valve 410, connecting the fourth port 414 and the seventh port 417, and the water flows through the radiator 610 and the motor electronic control component 600 in sequence through the seventh port 417, and then flows to the first port 411 of the nine-way water valve 410, connecting the first port 411 and the sixth port 416, and the water flows back to the third water pump 230 through the sixth port 416, so as to realize the battery natural cooling mode or the electric drive energy storage mode in the thermal management mode. At this time, the refrigerant integrated module 300 does not need to be operated.
[0146] Continue to refer Figure 1 On the basis of the above embodiment, in another possible implementation manner, in the water circuit integrated module 200, the water of the third water pump 230 can flow through the power battery 500, and then flow to the fourth port 414 of the nine-way water valve 410, connecting the fourth port 414 and the seventh port 417, and the water flows through the radiator 610 and the motor electronic control component 600 in sequence through the seventh port 417, and then flows to the first port 411 of the nine-way water valve 410, connecting the first port 411 and the third port 413, and the water flows through the second water valve 410 in sequence through the third port 413. The second water circuit in the pump 220 and the heat exchanger 340 then flows to the first valve port 440 of the second three-way water valve 430, then flows out from the third valve port 460 of the second three-way water valve 430, and then flows to the fifth port 415 of the nine-way water valve 410, connecting the fifth port 415 and the sixth port 416, and through the sixth port 416, the water flows to the first valve port 440 of the first three-way water valve 420, and then flows out from the third valve port 460 of the first three-way water valve 420, and finally returns to the third water pump 230, so as to realize the battery natural cooling mode or the electric drive energy storage mode in the thermal management mode. At this time, the refrigerant integrated module 300 does not need to be operated.
[0147] Among them, in the battery cooling mode, during slow charging at low temperature and normal temperature, the battery temperature is lowered by natural heat dissipation to achieve battery cooling. In addition, in the electric drive energy storage mode, in extremely low or low temperature scenarios, in order to avoid the performance degradation of the battery at low temperatures, the electric drive energy storage mode is used to keep the battery in a suitable temperature range to ensure battery performance and life.
[0148] Continue to refer Figure 1On the basis of the above embodiment, the thermal management system 100 may further include: an expansion kettle 800. The expansion kettle 800 may have two refilling ports, one of which may be connected to the inlet of the first water pump 210, and the other of which may be connected to the inlet of the second water pump 220. It is understandable that the expansion kettle 800 can replenish the first water pump 210 and the second water pump 220 in sequence, and the expansion kettle 800 has a certain auxiliary exhaust function when the coolant is added, thereby increasing the filling rate of the coolant. In a possible implementation, the expansion kettle 800 may include two independent kettles, so as to replenish the first water pump 210 and the second water pump 220 respectively.

In the embodiment of the present application, the number of the pressure temperature sensors 390 is two for example, and the two pressure temperature sensors 390 may be located at the inlet and outlet of the compressor 310, respectively.

The inlet end of the evaporator 720 can be directly connected to the inlet end of the compressor 310, thereby replacing the first check valve 370 and further reducing the number of valve bodies.
