[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In the absence of conflict, the following embodiments and features in the implementation methods can complement or combine with each other.

[0018] This application provides a specific embodiment of a thermal management system. The thermal management system of this embodiment is not only applicable to vehicles, but also to other heat exchange systems that require thermal management. For ease of description, the specification of this application uses an application to a vehicle as an example.

[0019] like Figures 6 to 8 As shown, the thermal management system includes a gas-liquid separator 1, a compressor 2, an indoor condenser 21, an indoor evaporator 22, an outdoor heat exchanger 23, a first valve 3, a second valve 4, a third valve 5, a fourth valve 6, a fifth valve 7, and a sixth valve 8.

[0020] The first valve 3, the second valve 4, and the fourth valve 6 are solenoid valves, each with both full-flow and closed states. The third valve 5 and the fifth valve 7 are both full-flow bidirectional throttling valves, each with full-flow, throttling, closed, and flow regulating states. The sixth valve 8 is an electronic expansion valve or a thermostatic expansion valve, with both throttling and closed states. In some other embodiments, any of the above valves may be other types of valves or combinations of at least two valves, as long as the functional requirements are met; this application does not impose any restrictions.

[0021] In this embodiment, the outlet of compressor 2, the first port of fourth valve 6, and the first port of fifth valve 7 are connected. The second port of fifth valve 7 is connected to the inlet of indoor condenser 21. The outlet of indoor condenser 21, the first port of third valve 5, and the first port of sixth valve 8 are connected. The second port of third valve 5, the first port of second valve 4, and the first port of outdoor heat exchanger 23 are connected. The second port of outdoor heat exchanger 23, the first port of first valve 3, and the second port of fourth valve 6 are connected. The second port of sixth valve 8 is connected to the first port of indoor evaporator 22. The second port of indoor evaporator 22, the second port of first valve 3, the second port of second valve 4, and the inlet of gas-liquid separator 1 are connected. The outlet of gas-liquid separator 1 is connected to the inlet of compressor 2.

[0022] The indoor condenser 21 and indoor evaporator 22 are air-cooled heat exchangers used for heat exchange with the air inside the air conditioning unit 200, which can be used to regulate the temperature and humidity of the passenger cabin. The outdoor heat exchanger 23 is a water-cooled heat exchanger used for heat exchange between the refrigerant in the refrigerant circuit and the coolant in the coolant circuit. The first and second ports of the outdoor heat exchanger 23 mentioned above are for refrigerant inflow and outflow, and the outdoor heat exchanger 23 also has two ports for coolant inflow and outflow. In some other embodiments, the heat exchanger types of the indoor condenser 21, indoor evaporator 22, and outdoor heat exchanger 23 can be changed according to system requirements, and other heat exchangers with different functions, such as waste heat recovery devices, can be added. Accordingly, the system connection status is adaptively adjusted.

[0023] When the passenger cabin requires heating, the thermal management system operates in heating mode. When the coolant circuit has sufficient heat, the thermal management system operates in the first heating mode, referencing... Figure 6 The first valve 3 and the fifth valve 7 are in the fully open state, the second valve 4, the fourth valve 6 and the sixth valve 8 are in the closed state, and the third valve 5 is in the throttling state. The outlet of the compressor 2, the indoor condenser 21, the outdoor heat exchanger 23, the gas-liquid separator 1 and the inlet of the compressor 2 are connected in sequence. The indoor condenser 21 releases heat to achieve heating, and heat is obtained from the coolant circuit through the outdoor heat exchanger 23.

[0024] When heat cannot be obtained from the coolant circuit, the thermal management system operates in a second heating mode, refer to... Figure 6 The second valve 4 is in the fully open state, the first valve 3, the fourth valve 6, and the sixth valve 8 are in the closed state, and at least one of the third valve 5 and the fifth valve 7 is in the throttling state. The outlet of the compressor 2, the indoor condenser 21, the gas-liquid separator 1, and the inlet of the compressor 2 are connected in sequence. The indoor condenser 21 releases heat to achieve heating, and the compressor 2 performs work to provide heat.

[0025] When heat can be obtained from the coolant circuit but is insufficient, the thermal management system operates in the third heating mode, as per [reference needed]. Figure 6 The first valve 3 and the second valve 4 are in the fully open state, the fourth valve 6 and the sixth valve 8 are in the closed state, and at least one of the third valve 5 and the fifth valve 7 is in the throttling state. The outlet of the compressor 2, the indoor condenser 21, the gas-liquid separator 1 and the inlet of the compressor 2 are connected in sequence. The outlet of the compressor 2, the indoor condenser 21, the outdoor heat exchanger 23, the gas-liquid separator 1 and the inlet of the compressor 2 are connected in sequence. The indoor condenser 21 releases heat to achieve heating, the compressor 2 does work to provide heat, and obtains heat from the coolant circuit through the outdoor heat exchanger 23.

[0026] Reference Figure 7 When the passenger cabin requires cooling, the thermal management system operates in cooling mode. Valve 3, valve 4, and valve 7 are in the off state, valve 5 and valve 6 are in the fully open state, and valve 8 is in the throttling state. The outlet of compressor 2, outdoor heat exchanger 23, indoor evaporator 22, gas-liquid separator 1, and inlet of compressor 2 are sequentially connected. The indoor evaporator 22 absorbs heat to achieve cooling.

[0027] When the passenger cabin requires heating and dehumidification, the thermal management system operates in heating and dehumidification mode. When the passenger cabin requires less heating, the thermal management system operates in the first heating and dehumidification mode, as per [reference needed]. Figure 8 The first valve 3 and the second valve 4 are in the closed state, the third valve 5, the fourth valve 6, and the fifth valve 7 are in the fully open state, and the sixth valve 8 is in the throttling state. The outlet of compressor 2, outdoor heat exchanger 23, indoor evaporator 22, gas-liquid separator 1, and inlet of compressor 2 are sequentially connected, as are the outlet of compressor 2, indoor condenser 21, indoor evaporator 22, gas-liquid separator 1, and inlet of compressor 2. In the first heating and dehumidification mode, the outdoor heat exchanger 23 shares part of the heat release function, thereby regulating the outlet air temperature of the air conditioning unit 200. In some embodiments, at least one of the third valve 5 and the fifth valve 7 can be adjusted to a flow regulation state, thereby regulating the refrigerant flow ratio of the two branches of the outdoor heat exchanger 23 and the indoor condenser 21.

[0028] When passenger cabin heating demand is high, the thermal management system operates in a second heating and dehumidification mode, referring to... Figure 9The second valve 4 and the fourth valve 6 are in the closed state, the first valve 3 and the fifth valve 7 are in the fully open state, and the third valve 5 and the sixth valve 8 are in the throttling state. The outlet of compressor 2, indoor condenser 21, outdoor heat exchanger 23, gas-liquid separator 1, and inlet of compressor 2 are connected in sequence. In the second heating and dehumidification mode, outdoor heat exchanger 23 recovers heat from the coolant circuit, thereby increasing the outlet air temperature of air conditioning unit 200.

[0029] In related technologies, the various components of a thermal management system are connected and linked through pipelines. To achieve switching between different modes, a large number of pipelines are required, and numerous T-joint-like components are incorporated, resulting in a complex structure and significant space occupation for the thermal management system. This application provides a flow path management component 100, which integrates several system components, reducing the number of connecting pipelines and minimizing the space occupied by the thermal management system.

[0030] According to a specific embodiment of the flow path management component 100 of this application, such as Figures 1 to 5 As shown, the flow path management assembly 100 includes a cylindrical portion 10, a block portion 20, a first valve core assembly 30, and a second valve core assembly 40. The cylindrical portion 10, the first valve core assembly 30, and the second valve core assembly 40 are all mounted on the block portion 20. Specifically, the cylindrical portion 10 is located on one side of the block portion 20 in the thickness direction, and the first valve core assembly 30 and the second valve core assembly 40 are located on the other side of the block portion 20 in the thickness direction.

[0031] Parts of the first valve core assembly 30 and the second valve core assembly 40 can move relative to the block portion 20, thereby enabling the connection and disconnection between the two channels. Optionally, both the first valve core assembly 30 and the second valve core assembly 40 are solenoid valve core assemblies, with the first valve core assembly 30 and the block portion 20 forming the first valve 3, and the second valve core assembly 40 and the block portion 20 forming the second valve 4.

[0032] The block portion 20 has a first channel 101, a second channel 102, a third channel 103, a first mounting channel 113, and a second mounting channel 114. The first channel 101 communicates with the inner cavity of the cylindrical portion 10. A first valve core assembly 30 is at least partially located in the first mounting channel 113, and the first valve core assembly 30 is used to control the connection or disconnection between the second channel 102 and the inner cavity of the cylindrical portion 10. A second valve core assembly 40 is at least partially located in the second mounting channel 114, and the second valve core assembly 40 is used to control the connection or disconnection between the third channel 103 and the inner cavity of the cylindrical portion 10.

[0033] In this embodiment, the block portion 20 has a fourth channel 104 and a fifth channel 105, which are respectively connected to the first channel 101. The first valve core assembly 30 is used to control the connection or disconnection of the second channel 102 and the fourth channel 104, and the second valve core assembly 40 is used to control the connection or disconnection of the third channel 103 and the fifth channel 105.

[0034] In some other embodiments, the fourth channel 104, the fifth channel 105, and the first channel 101 are not connected in the block portion 20. The fourth channel 104 is connected to the inner cavity of the cylindrical portion 10, and the fifth channel 105 is connected to the inner cavity of the cylindrical portion 10. When the first mounting channel 113 connects the second channel 102 and the fourth channel 104, and the second mounting channel 114 connects the third channel 103 and the fifth channel 105, the first channel 101, the second channel 102, and the third channel 103 are not connected in the block portion 20, and the first channel 101, the second channel 102, and the third channel 103 are respectively connected to the inner cavity of the cylindrical portion 10.

[0035] The first channel 101 penetrates the surface of the block portion 20 and communicates with the external space of the block portion 20. When the flow path management assembly 100 does not include other components, the second channel 102 and the third channel 103 both penetrate the surface of the block portion 20 and communicate with the external space of the block portion 20, but are not connected within the block portion 20.

[0036] The flow path management component 100 includes a cover 13 and a guide pipe 12. The cover 13, guide pipe 12, cylindrical portion 10, and block portion 20 can constitute a gas-liquid separator 1. In this embodiment, the block portion 20 and the cylindrical portion 10 are located on opposite sides of the cover 13. The guide pipe 12, cylindrical portion 10, and block portion 20 are all installed together with the cover 13 and sealed together. The peripheral sidewall of the cover 13 and the cylindrical portion 10 form the outer cylinder 11 of the gas-liquid separator 1. Part of the guide pipe 12 is located inside the cylindrical portion 10, and another part is located inside the cover 13. The cover 13 isolates the inlet channel of the gas-liquid separator 1 from the inlet end of the guide pipe 12, preventing them from directly communicating. In some other embodiments, the cylindrical portion 10 can be directly installed together with the block portion 20, and the cover 13 is located in the inner cavity of the cylindrical portion 10. The cover 13 is fixed to the cylindrical portion 10 or the block portion 20.

[0037] The block portion 20 has a sixth channel 106 that penetrates the surface of the block portion 20 and communicates with the external space of the block portion 20. One end of the guide tube 12 is sealed to the umbrella cover 13, the sixth channel 106 communicates with the inner cavity of the guide tube 12, and the other end of the guide tube 12 is an open end, with the inner cavity of the guide tube 12 communicating with the inner cavity of the cylinder portion 10.

[0038] When the thermal management system is running, the refrigerant enters the gas-liquid separator 1 through at least one of the fourth channel 104, the fifth channel 105 and the first channel 101 and impacts the umbrella cover 13. After entering the inner cavity of the cylinder section 10, the liquid refrigerant sinks and is stored in the inner cavity of the cylinder section 10, while the gaseous refrigerant floats into the inner cavity of the guide pipe 12 and then flows out of the gas-liquid separator 1 through the sixth channel 106, thereby completing the gas-liquid separation function.

[0039] In some embodiments, the flow path management component 100 includes a third valve core assembly 50, a portion of which is movable relative to the block portion 20 to enable communication and disconnection between the two channels, as well as throttling and flow regulation functions. Optionally, the third valve core assembly 50 is a full-pass bidirectional throttling valve core, and the third valve core assembly 50 and the block portion 20 form a third valve 5. The block portion 20 has a seventh channel 107, an eighth channel 108, and a third mounting channel 115, with the seventh channel 107 communicating with the third channel 103. Both the seventh channel 107 and the eighth channel 108 penetrate the surface of the block portion 20 and communicate with the external space of the block portion 20, but are not interconnected within the block portion 20. The third valve core assembly 50 is at least partially located in the third mounting channel 115. The third valve core assembly 50 is used to control the connection or disconnection of the third channel 103 and the eighth channel 108, and to regulate the flow rate between the third channel 103 and the eighth channel 108 when the third channel 103 and the eighth channel 108 are connected.

[0040] In some embodiments, the flow path management component 100 includes a fourth valve core assembly 60, a portion of which is movable relative to the block portion 20 to enable connection and disconnection between the two channels. Optionally, the fourth valve core assembly 60 is a shut-off valve core, and the fourth valve core assembly 60 and the block portion 20 form a fourth valve 6. The block portion 20 has a ninth channel 109, a tenth channel 110, and a fourth mounting channel 116. The ninth channel 109 communicates with the second channel 102. Both the ninth channel 109 and the tenth channel 110 penetrate the surface of the block portion 20 and communicate with the external space of the block portion 20, but are not interconnected within the block portion 20. The fourth valve core assembly 60 is at least partially located in the fourth mounting channel 116 and is used to control the connection or disconnection of the second channel 102 and the tenth channel 110.

[0041] In some embodiments, the flow management component 100 includes a fifth valve core assembly 70, a portion of which is movable relative to the block portion 20 to enable communication and disconnection between the two channels, as well as throttling and flow regulation functions. Optionally, the fifth valve core assembly 70 is a full-flow bidirectional throttling valve core, and the fifth valve core assembly 70 and the block portion 20 form a fifth valve 7. The block portion 20 has an eleventh channel 111, a twelfth channel 112, and a fifth mounting channel 117. The eleventh channel 111 and the twelfth channel 112 both penetrate the surface of the block portion 20, and are respectively connected to the external space of the block portion 20, but are not connected within the block portion 20. The fifth valve core assembly 70 is at least partially located in the fifth mounting channel 117. The fifth valve core assembly 70 is used to control the connection or disconnection of the eleventh channel 111 and the twelfth channel 112, and to regulate the flow rate between the eleventh channel 111 and the twelfth channel 112 when the eleventh channel 111 and the twelfth channel 112 are connected.

[0042] In this embodiment, the tenth channel 110 and the eleventh channel 111 are connected, and together they form a T-shaped channel, creating an interface on the surface of the block portion 20. In some other embodiments, the tenth channel 110 and the eleventh channel 111 are not connected within the block portion 20, and each of the tenth channel 110 and the eleventh channel 111 forms an interface on the surface of the block portion 20.

[0043] The block portion 20 includes a first interface portion S1, a second interface portion S2, a third interface portion S3, a fourth interface portion S4, a fifth interface portion S5, a sixth interface portion S6, and a seventh interface portion S7. The openings of the seven interface portions are formed on the outer surface of the block portion 20, and the seven openings are not connected on the outer surface of the block portion 20.

[0044] One end of the pipe in the system is sealed to the first interface S1, and the other end is sealed to the outlet of the compressor 2, thus connecting the tenth and eleventh channels 110 and 111 to the outlet of the compressor 2. One end of the pipe in the system is sealed to the second interface S2, and the other end is sealed to the inlet of the indoor condenser 21, thus connecting the twelfth channel 112 to the inlet of the indoor condenser 21. One end of the pipe in the system is sealed to the third interface S3, and the other end is sealed to the second port of the outdoor heat exchanger 23, thus connecting the ninth channel 109 to the second port of the outdoor heat exchanger 23. One end of the pipe in the system is sealed to the fourth interface S4, and the other end is sealed to the outlet of the indoor evaporator 22, thus connecting the first channel 101 to the outlet of the indoor evaporator 22. One end of the pipe in the system is sealed to the fifth interface S5, and the other end is sealed to the inlet of the compressor 2, thus connecting the sixth channel 106 to the inlet of the compressor 2. One end of the pipe in the system is sealed to the sixth interface S6, and the other end is sealed to the inlet of the sixth valve 8 and the outlet of the indoor condenser 21, respectively, so that the eighth channel 108 is connected to the inlet of the sixth valve 8 or to the outlet of the indoor condenser 21. One end of the pipe in the system is sealed to the seventh interface S7, and the other end is sealed to the first port of the outdoor heat exchanger 23, so that the seventh channel 107 is connected to the first port of the outdoor heat exchanger 23.

[0045] In some other embodiments, the block portion 20 also has a thirteenth channel, which communicates with the eighth channel 108. The thirteenth channel penetrates the surface of the block portion 20 and communicates with the external space of the block portion 20. The block portion 20 includes an eighth interface portion, where one end of the pipe in the system is sealed to the sixth interface portion S6, and the other end is sealed to the inlet of the sixth valve 8, thus connecting the eighth channel 108 to the inlet of the sixth valve 8. Similarly, one end of the pipe in the system is sealed to the eighth interface portion, and the other end is sealed to the outlet of the indoor condenser 21, thus connecting the thirteenth channel to the outlet of the indoor condenser 21. This configuration reduces the number of T-joint components in the system, reduces space occupation, and facilitates miniaturization.

[0046] When the thermal management system is in the first heating mode and the second heating and dehumidification mode, the first mounting port 113 connects to the second port 102 and the fourth port 104, the second valve core assembly 40 cuts off the third port 103 and the fifth port 105, the third mounting port 115 connects to the seventh port 107 and the eighth port 108, the fourth valve core assembly 60 cuts off the second port 102 and the tenth port 110, and the fifth mounting port 117 connects to the eleventh port 111 and the twelfth port 112. In the second heating and dehumidification mode, the refrigerant flowing from compressor 2 flows sequentially through the eleventh orifice 111, the twelfth orifice 112, and the indoor condenser 21, then splits into two paths: one path flows sequentially through the eighth orifice 108 and the seventh orifice 107 before flowing into the outdoor heat exchanger 23. Next, the refrigerant flowing from the outdoor heat exchanger 23 flows sequentially through the ninth orifice 109, the second orifice 102, and the fourth orifice 104 before entering the inner cavity of the cylinder section 10; the other path flows through the indoor evaporator 22 and then enters the inner cavity of the cylinder section 10 through the first orifice 101. Finally, the gaseous refrigerant flows from the sixth orifice 106 to the inlet of compressor 2, completing one cycle.

[0047] Compared to the second heating and dehumidification mode, in the first heating mode, the sixth valve 8 is in the closed state, and the refrigerant flowing out of the indoor condenser 21 only flows to the eighth orifice 108 and does not flow to the indoor evaporator 22.

[0048] When the thermal management system is in the second heating mode, the difference compared to the first heating mode is that the first valve core assembly 30 cuts off the second channel 102 and the fourth channel 104, and the second mounting channel 114 connects the third channel 103 and the fifth channel 105. In the second heating mode, the first valve 3 is in the closed state, and the refrigerant flowing out of the indoor condenser 21 flows sequentially through the eighth channel 108, the third channel 103 and the fifth channel 105 before entering the inner cavity of the cylinder section 10.

[0049] When the thermal management system is in the third heating mode, the difference compared to the first heating mode is that: the first mounting port 113 connects to the second port 102 and the fourth port 104, and the second mounting port 114 connects to the third port 103 and the fifth port 105. In the third heating mode, the refrigerant flowing out of the eighth port 108 is divided into two paths: one path flows sequentially through the third port 103 and the fifth port 105 before entering the inner cavity of the cylinder section 10; the other path flows sequentially through the seventh port 107, the outdoor heat exchanger 23, the ninth port 109, the second port 102, and the fourth port 104 before entering the inner cavity of the cylinder section 10.

[0050] When the thermal management system is in cooling mode and the first heating and dehumidification mode, the first valve core assembly 30 cuts off the second channel 102 and the fourth channel 104, the second valve core assembly 40 cuts off the third channel 103 and the fifth channel 105, and the third mounting channel 115 connects to the seventh channel 107 and the eighth channel 108. Specifically, in cooling mode, the fourth mounting channel 116 connects to the second channel 102 and the tenth channel 110, and the fifth valve core assembly 70 cuts off the eleventh channel 111 and the twelfth channel 112; in the first heating and dehumidification mode, the fourth mounting channel 116 connects to the second channel 102 and the tenth channel 110, and the fifth mounting channel 117 connects to the eleventh channel 111 and the twelfth channel 112.

[0051] In some other embodiments, the flow path management assembly 100 includes an outdoor heat exchanger 23, a ninth interface, and a tenth interface. The outdoor heat exchanger 23 is a water-cooled heat exchanger. The outdoor heat exchanger 23 is mounted together with the block portion 20 and is located beside the block portion 20. The outdoor heat exchanger 23 has a first flow channel and a second flow channel that are not interconnected. A ninth channel 109 is connected to one end of the first flow channel, and a seventh channel 107 is connected to the other end of the first flow channel. The first flow channel is used for refrigerant flow, and the second flow channel is used for coolant flow. When the thermal management system is in operation, the refrigerant and coolant in the outdoor heat exchanger 23 exchange heat. The ninth and tenth interface portions are used for installation with other components in the coolant circuit.

[0052] In some other embodiments, the flow path management assembly 100 includes a compressor 2, which is mounted together with the block portion 20 and located beside the block portion 20. A tenth channel 110 and an eleventh channel 111 communicate with the outlet of the compressor 2, and a sixth channel 106 communicates with the inlet of the compressor 2.

[0053] The appearance of the valve core assembly does not affect the realization of its function. The appearance of the valve core assembly can be selected according to the requirements, and even different valve core structures can be selected to achieve the same function. They should not be regarded as different parts.

[0054] It should be understood that the installation in this application can be direct installation or installation with intermediate spacer elements; the installation point is sealed, and the sealing connection can be achieved by brazing, gluing, or other methods. The "connection" between two components in this application can be direct connection or connection through pipelines. The two components can be connected only by pipelines in the system, or they can be connected by valves or other components.

[0055] Applying the flow path management component 100 of this application to a thermal management system can omit some piping and simplify the structure. In each embodiment, all valve core assemblies are located on the same side of the thickness direction of the block portion 20, and the valve core assemblies are arranged in a matrix, which is beneficial for the miniaturization of the flow path management component 100.
