[0025] The thermal management system and thermal management device of the technical solution of the present invention can have multiple implementation methods, at least one of which can be applied to a vehicle thermal management system, and at least one of which can be applied to other thermal management systems such as a household thermal management system or a commercial thermal management system. The following is an illustration of the thermal management device of a vehicle thermal management system with reference to the accompanying drawings.

[0026] See also Figure 1The thermal management system includes a compressor 10, a thermal management device 2000, a first radiator 40, a first heat absorber 70, a second radiator 60, and a battery thermostat 50. The first radiator 40 is capable of exchanging heat with ambient air, releasing heat to the ambient air. The second radiator 60 and the first heat absorber 70 are located in the vehicle's air conditioning unit to regulate the vehicle's interior temperature. The battery thermostat 50 is used to exchange heat with the battery to regulate the battery temperature and keep it operating within an appropriate temperature range. The thermal management device 2000 has a first inlet 2002, a first outlet 2001, a first coolant inlet 2004, a first coolant outlet 2003, a second coolant inlet 2006, a second coolant outlet 2005, a second inlet 2008, a second outlet 2007, a third inlet 2010, and a third outlet 2009. The outlet of the compressor 10 is connected to the first inlet 2002 of the thermal management device 2000, and the inlet of the compressor 10 is connected to the first outlet 2001 of the thermal management device 2000. The first coolant outlet 2003 can be connected to the first coolant inlet 2004 through the first radiator 40. The coolant discharged from the first coolant outlet 2003 enters the first radiator 40. After the coolant in the first radiator 40 releases heat, the coolant enters the thermal management device 2000 through the first coolant inlet 2004. Second coolant outlet 2005 can communicate with second coolant inlet 2006 via battery thermostat 50. Coolant discharged from second coolant outlet 2005 enters battery thermostat 50. Coolant in battery thermostat 50 exchanges heat with the battery, absorbing heat from the battery to regulate battery temperature. Second outlet 2007 of the thermal management device can communicate with second inlet 2008 via second radiator 60. The refrigerant discharged from second outlet 2007 of the thermal management device is high-temperature, high-pressure refrigerant, which releases heat at second radiator 60 and then enters thermal management device 2000 via second inlet 2008. Third outlet 2009 of the thermal management device can communicate with third inlet 2010 of the thermal management device via first heat absorber 70. Refrigerant discharged from third outlet 2009 is low-pressure, relatively low-temperature refrigerant, which evaporates and absorbs heat at first heat absorber 70, thereby reducing the temperature in the passenger compartment. It can be seen that the first coolant outlet 2003 flows out relatively high-temperature coolant, and the second coolant outlet 2005 flows out relatively low-temperature coolant.

[0027] In this embodiment, the thermal management system further includes a first pump 80 and a second pump 90 . The first pump 80 is used to drive the coolant to flow into and out of the first radiator 40 , and the second pump 90 is used to drive the coolant to flow into and out of the battery thermostat 50 .

[0028] The thermal management system includes a thermal management device 2000. The thermal management device 2000 as a whole has a port connected to the compressor 10 and the heat exchanger, which makes the connection of the various components of the thermal management system relatively simple and the layout of the thermal management system in the vehicle is also relatively simple.

[0029] See also Figure 2 The thermal management system also includes a water valve 30, which is used to select the flow direction of the coolant in the thermal management system. The water valve 30 has four inlets and four outlets. The first inlet 301 of the water valve 30 is connected to the outlet of the first pump 80, and the first outlet 302 of the water valve 30 is connected to the first coolant inlet 2004 of the thermal management device 2000. The second inlet 303 of the water valve 30 is connected to the outlet of the second pump 90, and the second outlet 304 of the water valve 30 is connected to the second coolant inlet 2006 of the thermal management device 2000. The third inlet 305 of the water valve 30 is connected to the outlet of the first radiator 40, and the third outlet 306 of the water valve 30 is connected to the inlet of the first radiator 40. The fourth inlet 307 of the water valve 30 is connected to the outlet of the battery thermostat 50, and the fourth outlet 308 of the water valve 30 is connected to the inlet of the battery thermostat 50. In this embodiment, the water valve 30 can be an eight-way water valve, or a combination of multiple valves, such as a three-way water valve or a four-way water valve.

[0030] In this embodiment, the water valve 30 has at least two operating states. In the first operating state, the passage between the first inlet 301 and the third outlet 306 of the water valve 30 is connected, and the passage between the third inlet 305 and the first outlet 302 of the water valve 30 is connected. Furthermore, the passage between the second inlet 303 and the fourth outlet 308 of the water valve 30 is connected, and the passage between the second inlet 303 and the fourth outlet 308 of the water valve 30 is connected. In this state, the relatively high-temperature coolant releases heat in the first radiator 40, while the relatively low-temperature coolant absorbs heat in the battery thermostat 50. In the second operating state, the passage between the first inlet 301 and the fourth outlet 308 of the water valve 30 is connected, and the passage between the fourth inlet 307 and the first outlet 302 of the water valve 30 is connected. In this state, the relatively high-temperature coolant enters the battery thermostat 50, raising the battery temperature.

[0031] See also Figure 9, the thermal management system may also include a powertrain heat exchanger 40', which exchanges heat with the vehicle's powertrain. The powertrain heat exchanger 40' may be arranged in series with the first radiator 40, and the serially arranged powertrain heat exchanger 40' and the first radiator 40 are connected to the third outlet 306 and the third inlet 305 of the water valve. At this time, the water valve also has a third working state: the channel between the third inlet 305 and the third outlet 306 is connected, and at this time the coolant of the powertrain heat exchanger 40' enters the first radiator 40 to release heat to reduce the temperature of the powertrain. In addition, the powertrain heat exchanger 40' may also be connected to the second coolant outlet and the second coolant inlet, and the coolant discharged from the second coolant outlet may be used to control the temperature of the powertrain, such as Figure 10 Indicates.

[0032] See also Figure 3 as well as Figure 7 ,exist Figure 3 and Figure 7In the figure, the arrow direction represents the flow direction of the refrigerant and coolant. The thermal management device 2000 includes a first dual-channel heat exchange module 2100, a second dual-channel heat exchange module 2200, a first valve module 2300 and a first throttle valve module 2400. The first dual-channel heat exchange module 2100 and the second dual-channel heat exchange module 2200 both include refrigerant flow channels and coolant flow channels. The refrigerant in the refrigerant flow channels and the coolant in the coolant flow channels can exchange heat. The coolant flow channels of the first dual-channel heat exchange module 2100, the first pump 80 and the first radiator 40 constitute all or part of the first coolant system. Here, "constituting part of the first coolant system" means that the first coolant system also includes other components, such as water valves or other heat exchangers. The coolant flow channels of the second dual-channel heat exchange module 2200, the second pump 90 and the battery thermostat 50 constitute part or all of the second coolant system. The first valve module 2300 has one inlet and two outlets. The outlet of the compressor 10 is connected to the inlet of the first valve module 2300, or in other words, the inlet of the first valve module 2300 is the first inlet 2002 of the thermal management device 2000 or is connected to the first inlet 2002 of the thermal management device 2000. One of the outlets of the first valve module 2300 is connected to the refrigerant inlet of the first dual-flow-channel heat exchange module 2100, and the other outlet is connected to the inlet of the second radiator 60. The first valve module 2300 can be an electrically controlled valve. The controller of the thermal management system can control the first valve module 2300 to select to be connected to the refrigerant inlet of the first dual-flow-channel heat exchange module 2100 and / or to be connected to the inlet of the second radiator 60, wherein the other outlet of the first valve module 2300 is the second outlet of the thermal management device 2000 or is connected to the second outlet of the thermal management device 2000. The first valve module 2300 may be a combination of two solenoid valves 2301 and 2302 or a combination of two two-way ball valves or a three-way ball valve. The first valve module 2300 may also be two electronic throttle valves with opening and closing functions.

[0033] The thermal management device 2000 further includes a first one-way module 2500 and a second one-way module 2600. Each of the first one-way module 2500 and the second one-way module 2600 has two inlets and one outlet. The first one-way module 2500 and the second one-way module 2600 have the same structure and function. Taking the first one-way module 2500 as an example, the first one-way module 2500 includes a first one-way unit 2501 and a second one-way unit 2502. The inlet of the first one-way unit 2501 is one inlet of the first one-way module 2500, and the inlet of the second one-way unit 2502 is another inlet of the first one-way module 2500. The outlets of the first one-way unit 2501 and the second one-way unit 2502 are connected to the outlet of the first one-way module 2500. It can be seen that due to the presence of the second one-way unit 2502, the refrigerant flowing into the first one-way module 2500 through the inlet of the first one-way unit 2501 can only flow out through the outlet of the first one-way module 2500. The refrigerant outlet of the first dual-flow-channel heat exchange module 2100 is connected to one inlet of the first one-way module 2500, and the outlet of the second radiator 60 is connected to the other inlet of the first one-way module 2500. It can be seen that after the refrigerant flowing out of the first dual-flow-channel heat exchange module 2100 enters the first one-way module 2500, it can only flow out of the outlet of the first one-way module 2500 and cannot flow into the second radiator 60. The second one-way module 2600 has two inlets and one outlet. One of the inlets of the second one-way module 2600 is connected to the outlet of the first heat absorber 70, and the other inlet of the second one-way module 2600 is connected to the refrigerant outlet of the second dual-flow heat exchange module 2200. The outlet of the second one-way module 2600 is the first outlet 2001 of the thermal management device 2000. When the thermal management device 2000 also includes a gas-liquid separator 2700, the outlet of the second one-way module 2600 can also be connected to the inlet of the compressor 10 through the gas-liquid separator 2700. In this way, the outlet of the gas-liquid separator 2700 is the first outlet 2001 of the heat pipe device. In other embodiments, the first and second one-way units can be one-way valves, solenoid valves, or ball valves.

[0034] The first throttle valve module 2400 has one inlet and two outlets. The outlet of the first one-way module 2500 is connected to the inlet of the first throttle valve module 2400. The first outlet of the first throttle valve module 2400 is connected to the inlet of the first heat absorber 70, and the second outlet of the first throttle valve module 2400 is connected to the refrigerant inlet of the second dual-flow-channel heat exchange module 2200. The first throttle valve module 2400 is capable of throttling the refrigerant entering the first throttle valve module 2400. The throttled refrigerant flows from the first outlet of the first throttle valve module 2400 into the first heat absorber 70 and / or from the second outlet of the first throttle valve module 2400 into the second dual-flow-channel heat exchange module 2200. In other embodiments, the first throttle valve module 2400 can also open and close the communication channel between its inlet and the first outlet of the first throttle valve module 2400. The first throttle valve module 2400 can also open and close the communication channel between its inlet and the second outlet of the first throttle valve module 2400. The first throttle valve module 2400 may be a combination of two electronic expansion valves 2401 and 2402 , or a combination of an electronic expansion valve and a three-way valve, or a ball valve with a throttling function.

[0035] The aforementioned components of the thermal management device 2000, such as the first dual-flow channel heat exchange module 2100, the second dual-flow channel heat exchange module 2200, the first throttle valve module 2400, the first valve module 2300, the first one-way module 2500, and the second one-way module 2600, can be mounted on a connecting plate, with each component connected via pipelines. In other embodiments, the thermal management device 2000 includes at least one valve body, and at least two of the first throttle valve module 2400, the first valve module 2300, the first one-way module 2500, and the second one-way module 2600 share a common valve body, which has flow channels connecting the aforementioned modules. In this way, the thermal management device 2000 has a high degree of integration and reduces the number of intermediate pipeline connections.

[0036] See also Figure 5 The thermal management device 2000 may further include a first pump module 80' and / or a second pump module 90'. The inlet of the first pump module 80' is connected to a coolant port of the first dual-channel heat exchange module 2100. In this case, the outlet of the first pump module 80' serves as the first coolant inlet 2004 of the thermal management device 2000 or the first coolant outlet 2003 of the thermal management device 2000. Another port of the first dual-channel heat exchange module 2100 serves as the first coolant inlet 2004 of the thermal management device 2000. The inlet of the second pump module 90' ​​is connected to a coolant port of the second dual-channel heat exchange module 2200. In this case, the outlet of the second pump module 90' ​​serves as the second coolant outlet 2005 of the thermal management device 2000. Another port of the second dual-channel heat exchange module 2200 serves as the second coolant inlet 2006 of the thermal management device 2000.

[0037] In other embodiments, the inlet of the first pump module 80' is connected to a coolant port of the first dual-channel heat exchange module 2100. In this case, the outlet of the first pump module 80' serves as the first coolant outlet 2003 of the thermal management device 2000, and the other port of the first dual-channel heat exchange module 2100 serves as the first coolant outlet 2004 of the thermal management device 2000. The inlet of the second pump module 90' ​​is connected to a coolant port of the second dual-channel heat exchange module 2200. In this case, the outlet of the second pump module 90' ​​serves as the first coolant outlet 2003 of the thermal management device 2000, and the other port of the second dual-channel heat exchange module 2200 serves as the second coolant inlet 2006 of the thermal management device 2000.

[0038] In this embodiment, the thermal management device 2000 includes a first pump module 80 ′ and a second pump module 90 ′. The thermal management system does not need to separately provide a first pump and a second pump, which further improves the integration of the thermal management device 2000 and simplifies the installation of the thermal management system.

[0039] See also Figure 6 The thermal management device 2000 also includes a water valve module 30', which has four inlets and four outlets. The first inlet 301' of the water valve module 30' is connected to the outlet of the first pump module 80', the inlet of the first pump module 80' is connected to a port of the first dual-flow-channel heat exchange module 2100, the first outlet 302' of the water valve module 30' is connected to another port of the first dual-flow-channel heat exchange module 2100, the second inlet 303' of the water valve module 30' is connected to the outlet of the second pump module 90', the second outlet 304' of the water valve module 30' is connected to the coolant inlet of the second dual-flow-channel heat exchange module 2200, and the third outlet 306' and the third inlet 305' of the water valve module 30' are the first coolant outlet 2003 and the first coolant inlet 2004 of the thermal management device 2000, respectively. The fourth outlet 308' and the fourth inlet 307' of the water valve module 30' respectively serve as the second coolant outlet 2005 and the second coolant inlet 2006 of the thermal management device 2000. In this embodiment, the thermal management device 2000 includes the water valve module 30', eliminating the need for a separate water valve in the thermal management system. This further improves the integration of the thermal management device 2000 and simplifies the installation of the thermal management system.

[0040] See also Figure 4 and Figure 8The thermal management system includes an outdoor heat exchanger 100, which is capable of exchanging heat with ambient air. The thermal management device 2000 also includes a second valve module 2800, wherein the second valve module 2800 has two inlets and two outlets, the first inlet 2013 of the second valve module 2800 is connected to the outlet of the second one-way module 2600, the first outlet 2011 of the second valve module 2800 is connected to one port of the outdoor heat exchanger 100, and the second inlet 2012 of the second valve module 2800 is connected to another port of the outdoor heat exchanger 100. When the thermal management device 2000 does not include the gas-liquid separator 2700, the second outlet 2014 of the second valve module 2800 is the first outlet of the thermal management device 2000. The second valve module 2800 includes a throttle portion 2801. When the first inlet 2013 of the second valve module 2800 and the first outlet 2011 of the second valve module 2800 are in communication, the throttle portion 2801 can throttle and reduce the pressure of the refrigerant, allowing the refrigerant to evaporate and absorb heat in the outdoor heat exchanger 100. The second valve module 2800 also includes a first on-off valve 2802. The first on-off valve 2802 can open and close the flow path between the first inlet 2013 of the second valve module 2800 and the second outlet 2014 of the second valve module 2800. When the first on-off valve 2802 is open, the outdoor heat exchanger 100 is bypassed, and the refrigerant is discharged from the second valve module 2800 through the second outlet 2014 of the second valve module 2800. The second valve module 2800 further includes a one-way portion 2803 that allows refrigerant to flow in one direction from the second inlet 2012 of the second valve module 2800 to the second outlet 2014 of the second valve module 2800. This prevents refrigerant at the second outlet 2014 of the second valve module 2800 or refrigerant discharged from the first on / off valve from flowing into the second inlet 2012 of the second valve module 2800, thereby preventing refrigerant at the second outlet 2014 of the second valve module 2800 from flowing back into the outdoor heat exchanger 100. In this embodiment, the first outlet 2011 of the second valve module 2800 serves as the fourth outlet of the thermal management device 2000 or communicates with the fourth outlet of the thermal management device 2000, the second inlet 2012 of the second valve module 2800 serves as the fourth inlet of the thermal management device 2000 or communicates with the fourth inlet of the thermal management device 2000, and the second outlet 2014 of the second valve module 2800 serves as the first outlet of the thermal management device 2000 or communicates with the first outlet of the thermal management device 2000. The thermal management device 2000 is integrated with the second valve module 2800 , which further improves the integration of the thermal management device 2000 and reduces the connecting pipelines of the thermal management system.The thermal management system includes an outdoor heat exchanger 100, and the thermal management device 2000 includes a second valve module 2800. After the first throttle valve module 2400 is throttled, the first heat absorber 70 and / or the second dual-flow heat exchange module 2200 evaporate and absorb heat. The second valve module 2800 can throttle again, and the outdoor heat exchanger 100 further evaporates and absorbs heat. The thermal management system can adjust the superheat of the first heat absorber 70 and / or the second heat absorber by adjusting the throttling part of the second valve module 2800 to facilitate the control of the temperature of the passenger compartment or the temperature of the battery.

[0041] See also Figure 11 and Figure 12 The thermal management device also includes a second switch valve 2804, and the second valve module 2800 is connected to the outlet of the first one-way module 2500 through the second switch valve 2804; of course, the second switch valve 2804 can also be a part of the second valve module 2800, one port of the second switch valve 2804 is the first inlet 2013 of the second valve module 2800, and the other port of the second switch valve 2804 is connected to the throttling part 2801 and the inlet of the first switch valve 2802, and the first inlet 2013 of the second valve module 2800 is connected to the outlet of the first one-way module 2500. When the first inlet 2013 of the second valve module 2800 is connected to the outlet of the first one-way module 2500, if the second radiator 60 and / or the first two-flow-channel heat exchanger 2100 release heat as a condenser, the refrigerant flowing out of the first one-way module 2500 can enter the outdoor heat exchanger without passing through the second two-flow-channel heat exchanger or the second heat absorber. The throttling part 2801 throttles the refrigerant, and the outdoor heat exchanger 100 absorbs heat for the evaporator; if the outdoor heat exchanger 100 is frosted or iced, the throttling part 2801 is fully opened, and the high-temperature and high-pressure refrigerant enters the outdoor heat exchanger to release heat, thereby removing the frost or ice from the outdoor heat exchanger 100. In other embodiments, the thermal management system includes a second valve module and an outdoor heat exchanger 100. In this case, the second valve module and the thermal management device are two independent devices. The first outlet of the second valve module is connected to the inlet of the outdoor heat exchanger 100, and the second inlet of the second valve module is connected to the outlet of the outdoor heat exchanger 100; the second valve module can throttle the refrigerant flowing through the second valve module and flow into the outdoor heat exchanger 100 from the first outlet of the second valve module, and the second valve module can open and close the flow channel between the first inlet of the second valve module and the second outlet of the second valve module; the first inlet of the second valve module is connected to the first outlet of the thermal management device 2000, and the second outlet of the second valve module is connected to the inlet of the compressor 10.
