"Inner, outer" refers to the inner and outer contours of the corresponding components. In addition, the terms "first", "second", etc. are only used for differentiation and cannot be understood as indicating or implying relative importance.

[0053] In the description of the present disclosure, it should also be noted that, unless otherwise explicitly specified and limited, the terms "provided", "connected", "connected", "mounted" should be understood broadly, for example, can be fixedly connected, can be detachably connected, or integrally connected; can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present disclosure can be understood according to the specific circumstances.

[0054] As a first aspect of the present disclosure, as shown in FIGS. 1-12, the present disclosure provides a vehicle thermal management system, comprising a compressor 1, a vehicle refrigerator 2, a heat exchange module 3, and a refrigerator expansion valve 4, the vehicle refrigerator 2 comprising a refrigerator heat exchanger 21 for exchanging heat with an article containing space of the vehicle refrigerator 2.

[0055] The outlet of the compressor 1 is connected with the first port 213 of the refrigerator heat exchanger 21 and the inlet of the heat exchange module 3, and the outlet of the compressor 1 can be selectively communicated or cut off with the first port 213 of the refrigerator heat exchanger 21 and the inlet of the heat exchange module 3, the second port 214 of the refrigerator heat exchanger 21 is communicated with the first port 43 of the refrigerator expansion valve 4, the second port 44 of the refrigerator expansion valve 4 can be selectively communicated with the inlet of the heat exchange module 3 or the outlet of the heat exchange module 3, and the inlet of the compressor 1 can be selectively communicated with the first port 213 of the refrigerator heat exchanger 21 or the outlet of the heat exchange module 3.

[0056] According to the vehicle thermal management system 100 provided by the present disclosure, by controlling the communication of the outlet of the compressor 1 with the first port 213 of the refrigerator heat exchanger 21 or the inlet of the heat exchange module 3, the communication of the second port 44 of the refrigerator expansion valve 4 with the inlet of the heat exchange module 3 or the outlet of the heat exchange module 3, and the communication of the inlet of the compressor 1 with the first port 213 of the refrigerator heat exchanger 21 or the outlet of the heat exchange module 3, the vehicle thermal management system 100 can have a vehicle refrigerator 2 cooling mode and a vehicle refrigerator 2 heating mode.

[0057] In the vehicle refrigerator 2 cooling mode, as shown in FIG. 7, the outlet of the compressor 1 can be communicated with the inlet of the heat exchange module 3, the outlet of the compressor 1 can be cut off with the first port 213 of the refrigerator heat exchanger 21 (i.e. the outlet of the compressor 1 can not be communicated with the first port 213 of the refrigerator heat exchanger 21), the second port 44 of the refrigerator expansion valve 4 can be communicated with the outlet of the heat exchange module 3, the first port 43 of the refrigerator expansion valve 4 is communicated with the second port 214 of the refrigerator heat exchanger 21, and the first port 213 of the refrigerator heat exchanger 21 is communicated with the inlet of the compressor 1, so that the compressor 1, the heat exchange module 3, the refrigerator expansion valve 4, and the refrigerator heat exchanger 21 are sequentially connected in series to form a loop. The high-temperature and high-pressure gaseous refrigerant discharged from the compressor 1 flows into the heat exchange module 3, the refrigerant can be heat released in the heat exchange module 3, the refrigerant discharged from the outlet of the heat exchange module 3 becomes low-temperature and low-pressure liquid refrigerant after throttling and pressure reduction by the refrigerator expansion valve 4, and the low-temperature and low-pressure liquid refrigerant flows into the refrigerator heat exchanger 21, absorbs heat from the article containing space in the refrigerator heat exchanger 21, and reduces the temperature in the article containing space to achieve the refrigeration or freezing function of the vehicle refrigerator. In the vehicle refrigerator 2 cooling mode, the refrigerator heat exchanger 21 is used as an evaporator.

[0058] In the heating mode of the vehicle refrigerator 2, as shown in FIG. 8, the outlet of the compressor 1 can be communicated with the first port 213 of the refrigerator heat exchanger 21, the outlet of the compressor 1 can be cut off with the inlet of the heat exchange module 3 (that is, the outlet of the compressor 1 is not communicated with the inlet of the heat exchange module 3), the second port 214 of the refrigerator heat exchanger 21 is communicated with the first port 43 of the refrigerator expansion valve 4, the second port 44 of the refrigerator expansion valve 4 is communicated with the inlet of the heat exchange module 3, and the outlet of the heat exchange module 3 is communicated with the inlet of the compressor 1, so that the compressor 1, the refrigerator heat exchanger 21, the refrigerator expansion valve 4, and the heat exchange module 3 are sequentially connected in series to form a loop. The high-temperature and high-pressure gaseous refrigerant discharged from the compressor 1 flows into the refrigerator heat exchanger 21, and the refrigerant releases heat to the article containing space in the refrigerator heat exchanger 21, thereby increasing the temperature in the article containing space, so that the article containing space can be used for heat preservation or heating of the article. The heat-released refrigerant flowing out of the second port 214 of the refrigerator heat exchanger 21 is throttled and depressurized by the refrigerator expansion valve 4 to become low-temperature and low-pressure liquid refrigerant, which flows into the heat exchange module 3 and absorbs heat in the heat exchange module 3. The low-temperature and low-pressure gaseous refrigerant flows out of the outlet of the heat exchange module 3, and finally returns to the compressor 1. In the heating mode of the vehicle refrigerator 2, the refrigerator heat exchanger 21 is used as a condenser.

[0059] Through the above technical solution, by controlling the communication relationship between the outlet of the compressor 1 and the first port 213 of the refrigerator heat exchanger 21 and the inlet of the heat exchange module 3, the communication relationship between the second port 44 of the refrigerator expansion valve 4 and the inlet of the heat exchange module 3 and the outlet of the heat exchange module 3, and the communication relationship between the inlet of the compressor 1 and the first port 213 of the refrigerator heat exchanger 21 and the outlet of the heat exchange module 3, the high-temperature and high-pressure gaseous refrigerant discharged from the compressor 1 can be released heat in the heat exchange module 3, and then absorb heat in the article containing space in the refrigerator heat exchanger 21, thereby realizing refrigeration of the vehicle refrigerator 2, or the high-temperature and high-pressure gaseous refrigerant discharged from the compressor 1 can enter the refrigerator heat exchanger 21 to release heat to the article containing space, thereby realizing heating of the vehicle refrigerator 2. Thus, the vehicle refrigerator 2 provided by the present disclosure can not only have refrigeration function, but also have heating function, the temperature adjustment range in the article containing space is wide, the function is rich, and the user's driving experience can be improved.

[0060] To increase the article storage space of the vehicle, optionally, as shown in FIG. 4, the vehicle-mounted refrigerators 2 can be multiple, each vehicle-mounted refrigerator 2 includes a refrigerator heat exchanger 21, the multiple refrigerator heat exchangers 21 are connected in parallel with each other, multiple refrigerator expansion valves 4 correspond to the multiple refrigerator heat exchangers 21 one by one, the outlet of the compressor 1 can be selectively communicated or cut off with the first port 213 of any refrigerator heat exchanger 21, the second port 44 of each refrigerator expansion valve 4 can be selectively communicated with the inlet of the heat exchange module 3 or the outlet of the heat exchange module 3, and the inlet of the compressor 1 can be selectively communicated with the first port 213 of any refrigerator heat exchanger 21 or the outlet of the heat exchange module 3. That is, the outlet of the compressor 1 can be communicated with the first port 213 of any refrigerator heat exchanger 21, and the second port 44 of any refrigerator expansion valve 4 can be communicated with the inlet of the heat exchange module 3, so that one of the multiple vehicle-mounted refrigerators 2 or the multiple vehicle-mounted refrigerators 2 simultaneously realize heating; the second port 44 of any refrigerator expansion valve 4 can be communicated with the outlet of the heat exchange module 3, and the inlet of the compressor 1 can be communicated with the first port 213 of any refrigerator heat exchanger 21, so that one of the multiple vehicle-mounted refrigerators 2 or the multiple vehicle-mounted refrigerators 2 simultaneously realize refrigeration. The arrangement of the multiple vehicle-mounted refrigerators 2 can improve the article storage space of the vehicle and improve the user's driving experience.

[0061] As shown in FIG. 4, the first port 213 of each refrigerator heat exchanger 21 can correspondingly be provided with a ninth switch valve 29. By controlling the conduction or cut-off of the corresponding ninth switch valve 29, it can be controlled whether the refrigerant flowing out of the compressor 1 flows into the refrigerator heat exchanger 21 corresponding to the ninth switch valve 29, realizing the above-mentioned that the outlet of the compressor 1 can be communicated with the first port 213 of any refrigerator heat exchanger 21, so that the multiple refrigerator heat exchangers 21 can simultaneously heat, and also can only partially heat.

[0062] The refrigerator expansion valve 4 can also control the on-off of the refrigerant flow path where the refrigerator heat exchanger 21 is located, that is, control whether the refrigerant flowing out of the outlet of the heat exchange module 3 can enter the refrigerator heat exchanger 21 or not, realizing the above-mentioned that the second port 44 of any refrigerator expansion valve 4 is communicated with the outlet of the heat exchange module 3, so that the multiple refrigerator heat exchangers 21 can simultaneously refrigerate, and also can only partially refrigerate. In addition, the refrigerator expansion valve 4 can also adjust the evaporation pressure and evaporation temperature of the refrigerant entering the corresponding refrigerator heat exchanger 21, so that the article containing space of the multiple vehicle-mounted refrigerators 2 can have different refrigeration temperatures or freezing temperatures.

[0080] Optionally, the second air hole 245 can be two, and the two second air holes 245 are located on the two sides of the first air hole 241 respectively, so as to form a circulating air flow sucked from the middle and discharged from the two sides, so that the air circulation range is larger and the efficiency is higher.

The refrigerant can absorb heat from the vehicle electrical device 32 or release heat to the vehicle electrical device 32 through the plate heat exchanger 33.

[0091] In another embodiment provided by the present disclosure, as shown in FIG. 1, the heat exchange module 3 comprises the outdoor heat exchanger 31, the outlet of the compressor 1 and the second port of the refrigerator expansion valve 4 are connected to the inlet of the outdoor heat exchanger 31, and the inlet of the compressor 1 and the second port of the refrigerator expansion valve 4 are connected to the outlet of the outdoor heat exchanger 31. The heat exchange module 3 further comprises the vehicle electrical device 32, the plate heat exchanger 33, the first flow path 34, and the second flow path 35, the outlet of the compressor 1 and the second port of the refrigerator expansion valve 4 are connected to the first inlet 331 of the plate heat exchanger 33, the inlet of the compressor 1 and the second port of the refrigerator expansion valve 4 are also connected to the first outlet 332 of the plate heat exchanger 33, the outlet of the first flow path 34 is connected to the second inlet 333 of the plate heat exchanger 33, the second outlet 334 of the plate heat exchanger 33 is connected to the inlet of the second flow path 35, the outlet of the second flow path 35 is connected to the inlet of the first flow path 34, and the vehicle electrical device 32 is arranged on the first flow path 34 and / or the second flow path 35.

In the heating mode of the vehicle refrigerator 2, the high-temperature and high-pressure refrigerant flowing out of the outlet of the compressor 1 flows into the refrigerator heat exchanger 21, then flows into the outdoor heat exchanger 31 and / or the plate heat exchanger 33 through the refrigerator expansion valve 4, absorbs heat from the atmosphere through the outdoor heat exchanger 31 and / or absorbs heat from the vehicle electrical device 32 through the plate heat exchanger 33, and finally returns to the compressor 1.

[0093] Due to the different heat sources and heat sinks of the outdoor heat exchanger 31 and the plate heat exchanger 33, different heat exchangers can be selected according to the situation of the vehicle electrical device 32 and the outdoor temperature during use. For example, in the case where the vehicle refrigerator 2 needs to be cooled and the vehicle electrical device 32 needs to be heated (for example, the vehicle electrical device 32 is a battery pack, and in the case where the battery pack needs to be preheated or heated), the high-temperature and high-pressure refrigerant flowing out of the compressor 1 can be introduced into the plate heat exchanger 33, and the cooling liquid in the first flow path 34 is heated by the refrigerant, so that the heated cooling liquid can raise the temperature of the vehicle electrical device 32. For example, in the case where the vehicle refrigerator 2 needs to be heated and the ambient temperature is low, the refrigerant flowing out of the refrigerator expansion valve 4 can be introduced into the plate heat exchanger 33, and the heat of the vehicle electrical device 32 is absorbed by the plate heat exchanger 33, thereby improving the heating effect of the vehicle refrigerator 2.

[0094] The present disclosure does not limit the specific type of the vehicle electrical device 32, for example, the vehicle electrical device 32 can include one or more of a battery pack, a motor, a motor controller, and a DC-DC converter.

[0095] Optionally, as shown in FIG. 1, the heat exchange module 3 further includes a seventh switch valve 36 and an eighth switch valve 37, the outlet of the compressor 1 and the second port 44 of the refrigerator expansion valve 4 are connected with the inlet of the outdoor heat exchanger 31 via the seventh switch valve 36, and the outlet of the compressor 1 and the second port 44 of the refrigerator expansion valve 4 are connected with the first inlet 331 of the plate heat exchanger 33 via the eighth switch valve 37. By controlling the opening and closing of the seventh switch valve 36 and the eighth switch valve 37, it can be controlled whether the refrigerant flowing out of the outlet of the compressor 1 flows into the outdoor heat exchanger 31 to release heat or flows into the plate heat exchanger 33 to release heat in the cooling mode of the vehicle refrigerator 2, and whether the refrigerant flowing out of the refrigerator expansion valve 4 flows into the outdoor heat exchanger 31 to absorb heat or flows into the plate heat exchanger 33 to absorb heat in the heating mode of the vehicle refrigerator 2.

[0096] Optionally, as shown in FIG. 1, the heat exchange module 3 further includes a radiator 38 and a fourth three-way valve 39, the A port of the fourth three-way valve 39 is connected with the inlet of the first flow path 34, the outlet of the second flow path 35 is connected with the B port of the fourth three-way valve 39 and the inlet of the radiator 38, and the C port of the fourth three-way valve 39 is connected with the outlet of the radiator 38.

[0097] When the A port and the B port of the fourth three-way valve 39 are connected, the first flow path 34, the plate heat exchanger 33, and the second flow path 35 are connected in series to form a loop, and the heat of the vehicle electrical device 32 can be dissipated to the refrigerant through the plate heat exchanger 33, so that the refrigerant can absorb heat at the vehicle electrical device 32, and the vehicle electrical device 32 can be cooled.

[0098] When the A port and the C port of the fourth three-way valve 39 are communicated, the first flow path 34, the radiator 38, the plate heat exchanger 33, and the second flow path 35 are connected in series to form a loop, and the refrigerant can pass through the plate heat exchanger 33 to dissipate heat to the coolant. When the coolant flows through the radiator 38, the heat is dissipated to the outside atmosphere through the radiator 38.

[0099] Optionally, a water pump 42 is arranged on the first flow path 34 or the second flow path 35.

[0100] Optionally, the vehicle thermal management system 100 further comprises an air conditioning system, and the air conditioning system comprises the above-mentioned compressor 1, that is, the compressor 1 connected with the refrigerator heat exchanger 21 is the compressor 1 of the air conditioning system. That is to say, the compressor 1 not only plays a role of compressing and driving the refrigerant in the refrigerant flow path where the devices (such as the air conditioning evaporator 19, the air conditioning condenser 16, etc.) of the air conditioning system are located, but also plays a role of compressing and driving the refrigerant in the refrigerant flow path where the refrigerator heat exchanger 21 of the vehicle refrigerator 2 is located, so as to achieve the effect of providing refrigerant for different thermal management devices by using the same compressor 1.

[0101] By using the compressor 1 in the air conditioning system to provide the refrigerant flowing through the refrigerator heat exchanger 21 of the vehicle refrigerator 2, the utilization rate of the compressor 1 can be improved, the integration of the vehicle thermal management system 100 can be improved, the number of devices required for refrigeration or heating of the vehicle refrigerator 2 can be reduced, and the cost significantly increased due to the arrangement of the vehicle refrigerator 2 can be avoided.

[0102] Optionally, as shown in FIG. 1, the air conditioning system further comprises an air conditioning condenser 16, a through-flow flow path 17, and a throttling flow path 18. The outlet of the compressor 1 is connected with the inlet of the air conditioning condenser 16. The outlet of the air conditioning condenser 16 is selectively connected with the inlet of the heat exchange module 3 through the through-flow flow path 17 or the throttling flow path 18.

[0103] In the heating mode of the air conditioning system, as shown in FIG. 10, the outlet of the air conditioning condenser 16 is communicated with the throttling flow path 18. The high-temperature and high-pressure refrigerant flowing out of the outlet of the compressor 1 flows into the air conditioning condenser 16, and then releases heat in the air conditioning condenser 16. The refrigerant after heat release is throttled and depressurized through the throttling flow path 18, and then becomes low-temperature and low-pressure gaseous refrigerant. The low-temperature and low-pressure gaseous refrigerant absorbs heat in the heat exchange module 3, and finally returns to the compressor 1. Since the refrigerant releases heat in the air conditioning condenser 16, heat can be provided to the passenger compartment to improve the temperature in the passenger compartment. As shown in FIG. 12, in the synchronous heating mode of the vehicle refrigerator and the air conditioning system, the outlet of the air conditioning condenser 16 is communicated with the throttling flow path 18.

[0104] As shown in FIG. 1, the air conditioning system further comprises an air conditioning evaporator 19 and a first air conditioning expansion valve 20. The outlet of the heat exchange module 3 is connected with the inlet of the air conditioning evaporator 19 through the first air conditioning expansion valve 20. The outlet of the air conditioning evaporator 19 is connected with the inlet of the compressor 1.

[0105] In the air conditioning refrigeration mode, as shown in FIG. 9, the outlet of the air conditioner condenser 16 is communicated with the through-flow flow path 17, the high-temperature and high-pressure gaseous refrigerant flowing out of the outlet of the compressor 1 flows into the air conditioner condenser 16, at this time, the heating fan 40 can be controlled not to blow air to the air conditioner condenser 16, that is, the refrigerant does not exchange heat at the air conditioner condenser 16, the air conditioner condenser 16 is used as a through-flow flow path, the refrigerant flowing out of the air conditioner condenser 16 flows into the through-flow flow path 17, since the refrigerant flowing through the through-flow flow path 17 is not subjected to pressure reduction by throttling, the refrigerant flowing into the heat exchange module 3 is still high-temperature and high-pressure gaseous refrigerant, after the high-temperature and high-pressure gaseous refrigerant is subjected to heat release by the heat exchange module 3, the refrigerant can flow to the first air conditioner expansion valve 20, after the refrigerant is subjected to pressure reduction by throttling by the first air conditioner expansion valve 20, the refrigerant flows into the air conditioner evaporator 19, absorbs heat of the passenger compartment in the air conditioner evaporator 19, and cools the passenger compartment, thereby achieving refrigeration of the passenger compartment. As shown in FIG. 11, in the synchronous refrigeration mode of the vehicle-mounted refrigerator and the air conditioning system, the outlet of the air conditioner condenser 16 is communicated with the through-flow flow path 17, the heating fan 40 does not blow air to the air conditioner condenser 16, that is, the refrigerant does not exchange heat at the air conditioner condenser 16, the air conditioner condenser 16 is used as a through-flow flow path, and the through-flow flow path 17 only allows the refrigerant to pass through and does not subject the refrigerant to pressure reduction by throttling.

[0106] As shown in FIG. 1, in an embodiment provided by the present disclosure, the through-flow flow path 17 is provided with the first switch valve 5, and the throttling flow path 18 is provided with the second air conditioner expansion valve 181, so that the through-flow flow path 17 can be communicated or cut off by the first switch valve 5, and the throttling flow path 18 can be cut off or throttled by the second air conditioner expansion valve 181.

[0107] In another embodiment provided by the present disclosure, as shown in FIG. 5, the air conditioning system further comprises an expansion switch valve 26, the inlet of the expansion switch valve 26 is connected with the outlet of the air conditioner condenser 16, the outlet of the expansion switch valve 26 is connected with the inlet of the heat exchange module 3, the through-flow flow path 17 is a through-flow flow passage in the expansion switch valve 26, the through-flow flow passage can be communicated or cut off by the refrigerant, and the throttling flow path 18 is a throttling flow passage in the expansion switch valve 26, the throttling flow passage can cut off or throttle the refrigerant. The expansion switch valve 26 can be regarded as an integrated valve integrating an expansion valve and a switch valve.

[0108] For the embodiment in which the air conditioning system comprises the expansion switch valve 26, as shown in FIG. 5, the first switch valve 5 can be arranged at the inlet of the air conditioner condenser 16.

[0109] Optionally, as shown in FIG. 1, the air conditioning system further comprises a heating fan 40 and an electric heater 41, the electric heater 41 is arranged close to the air conditioning condenser 16, and the heating fan 40 is used to blow air to the air conditioning condenser 16 and the electric heater 41. The heating fan 40 can generate air blowing through the air conditioning condenser 16 or the electric heater 41 when the air conditioning system is in the heating mode, so that the air in the vehicle passenger compartment can exchange heat with the air conditioning condenser 16 or the electric heater 41, thereby increasing the temperature in the passenger compartment.

[0110] Optionally, the electric heater 41 can be a PTC heater.

[0111] Optionally, as shown in FIG. 1, the air conditioning system further comprises a gas-liquid separator 30, the inlet of the gas-liquid separator 30 is connected with the first port of the refrigerator heat exchanger 21, the outlet of the heat exchange module 3 and the outlet of the air conditioning evaporator 19, and the outlet of the gas-liquid separator 30 is connected with the inlet of the compressor 1, so that the refrigerant flowing out of the first port 213 of the refrigerator heat exchanger 21, the outlet of the heat exchange module 3 and the outlet of the air conditioning evaporator 19 can pass through the gas-liquid separator 30 to separate the liquid from the gas in the refrigerant, thereby making the gaseous refrigerant return to the compressor 1 to prevent the compressor 1 from being damaged.

[0112] To facilitate understanding of the working modes of the vehicle thermal management system provided by the present disclosure, the following will take the embodiment shown in FIG. 1 as an example, and combine FIGS. 7-12 to specifically introduce the working processes of several main working modes of the vehicle thermal management system provided by an embodiment of the present disclosure.

[0113] I. Refrigerator cooling mode of vehicle-mounted refrigerator

[0114] Referring to FIG. 7, in this mode, the first switch valve 5 is opened, the second air conditioning expansion valve 181 is closed, the second switch valve 6 is closed, at least one of the seventh switch valve 36 and the eighth switch valve 37 is opened, the refrigerator expansion valve 4 is opened, the sixth switch valve 14 is opened, the fifth switch valve 13 is closed, the first air conditioning expansion valve 20 is closed, and the heating fan 40 is closed. In this mode, the compressor 1, the air conditioning condenser 16, the heat exchange module 3, the refrigerator expansion valve 4 and the refrigerator heat exchanger 21 are connected in series to form a loop.

[0115] The high-temperature and high-pressure gaseous refrigerant flowing out of the outlet of the compressor 1 flows into the air conditioner condenser 16. Since the heating fan 40 is closed, i.e. the heating fan 40 does not blow air to the air conditioner condenser 16, the high-temperature and high-pressure gaseous refrigerant does not release heat at the air conditioner condenser 16. The air conditioner condenser 16 is used as a flow passage. The high-temperature and high-pressure gaseous refrigerant flows into the heat exchange module 3 and releases heat in the heat exchange module 3. The refrigerant flowing out of the outlet of the heat exchange module 3 becomes low-temperature and low-pressure liquid refrigerant after throttling and pressure reduction by the refrigerator expansion valve 4. The low-temperature and low-pressure liquid refrigerant flows into the refrigerator heat exchanger 21, absorbs heat of the article containing space, and reduces the temperature in the article containing space to achieve the refrigeration or freezing function of the vehicle refrigerator 2. After absorbing heat in the refrigerator heat exchanger 21, the refrigerant finally returns to the compressor 1.

[0116] It should be noted that in this mode, if the seventh switch valve 36 is opened, the high-temperature and high-pressure gaseous refrigerant flows into the outdoor heat exchanger 31 and releases heat to the outside atmosphere in the outdoor heat exchanger 31; if the eighth switch valve 37 is opened and the A port and the B port of the fourth three-way valve 39 are communicated, the high-temperature and high-pressure gaseous refrigerant flows into the plate heat exchanger 33 and releases heat to the cooling liquid in the plate heat exchanger 33. The heat-absorbed cooling liquid can be used to heat the vehicle electrical components 32 when the vehicle electrical components 32 include a battery pack, for example, and the battery pack can be heated by the heat of the refrigerant; if the eighth switch valve 37 is opened and the A port and the C port of the fourth three-way valve 39 are communicated, the high-temperature and high-pressure gaseous refrigerant flows into the plate heat exchanger 33 and releases heat to the cooling liquid in the plate heat exchanger 33. The heat-absorbed cooling liquid can release heat to the outside atmosphere through the radiator 38 when flowing through the radiator 38.

[0117] In addition, in the vehicle refrigerator refrigeration mode, the cooling component of the vehicle refrigerator 2 can also be turned on to improve the refrigeration efficiency and achieve rapid refrigeration.

[0118] II. Vehicle refrigerator heating mode

[0119] Referring to FIG. 8, in this mode, the first switch valve 5 is closed, the second air conditioner expansion valve 181 is closed, the second switch valve 6 is opened, at least one of the seventh switch valve 36 and the eighth switch valve 37 is opened, the refrigerator expansion valve 4 is opened, the sixth switch valve 14 is closed, the fifth switch valve 13 is opened, and the first air conditioner expansion valve 20 is closed. In this mode, the compressor 1, the refrigerator heat exchanger 21, the refrigerator expansion valve 4, and the heat exchange module 3 are connected in series to form a loop.

[0120] The high-temperature and high-pressure gaseous refrigerant flowing out of the outlet of the compressor 1 flows into the refrigerator heat exchanger 21 and releases heat in the refrigerator heat exchanger 21 to raise the temperature of the article containing space, thereby achieving the heat preservation or heating function of the vehicle refrigerator 2. The refrigerant released heat in the refrigerator heat exchanger 21 flows into the liquid refrigerant of low temperature and low pressure after being throttled and depressurized by the refrigerator expansion valve 4, and the liquid refrigerant of low temperature and low pressure flows into the heat exchange module 3 and absorbs heat in the heat exchange module 3. The outlet of the heat exchange module 3 flows out the low-temperature and low-pressure gaseous refrigerant, which finally returns to the compressor 1.

[0121] It should be noted that in this mode, if the seventh switch valve 36 is opened, the low-temperature and low-pressure liquid refrigerant flows into the outdoor heat exchanger 31 and absorbs the heat of the outside atmosphere in the outdoor heat exchanger 31; if the eighth switch valve 37 is opened and the A port and the B port of the fourth three-way valve 39 are communicated, the low-temperature and low-pressure liquid refrigerant flows into the plate heat exchanger 33 and absorbs the heat of the cooling liquid in the plate heat exchanger 33. The cooled cooling liquid can be used to cool the vehicle electrical components 32 when flowing through the vehicle electrical components 32, for example, when the vehicle electrical components 32 include a motor, the cold energy of the refrigerant can be used to cool the motor.

[0122] In addition, in the heating mode of the vehicle refrigerator, the heating element 28 of the vehicle refrigerator 2 can also be turned on to improve the heating efficiency and achieve rapid heating.

[0123] III. Air conditioning system refrigeration mode

[0124] Referring to FIG. 9, in this mode, the first switch valve 5 is opened, the second air conditioning expansion valve 181 is closed, the second switch valve 6 is closed, at least one of the seventh switch valve 36 and the eighth switch valve 37 is opened, the refrigerator expansion valve 4 is closed, the sixth switch valve 14 is closed, the fifth switch valve 13 is closed, the second one-way valve 9 is closed, the first air conditioning expansion valve 20 is opened, and the heating fan 40 is closed. In this mode, the compressor 1, the air conditioning condenser 16, the heat exchange module 3, the first air conditioning expansion valve 20, and the air conditioning evaporator 19 are connected in series to form a loop.

[0125] The high-temperature and high-pressure gaseous refrigerant flowing out of the outlet of the compressor 1 flows into the air conditioning condenser 16. Since the heating fan 40 is closed, i.e. the heating fan 40 does not blow air to the air conditioning condenser 16, the high-temperature and high-pressure gaseous refrigerant does not release heat in the air conditioning condenser 16, and the air conditioning condenser 16 is used as a flow passage. The high-temperature and high-pressure gaseous refrigerant flows into the heat exchange module 3 and releases heat in the heat exchange module 3. The refrigerant flowing out of the outlet of the heat exchange module 3 is throttled and depressurized by the first air conditioning expansion valve 20 to become low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant flows into the air conditioning evaporator 19 and absorbs the heat of the passenger compartment in the air conditioning evaporator 19 to lower the temperature of the passenger compartment, thereby achieving air conditioning refrigeration. The refrigerant after absorbing heat in the air conditioning evaporator 19 finally returns to the compressor 1.

[0126] It should be noted that in this mode, if the seventh switch valve 36 is opened, the high-temperature and high-pressure gaseous refrigerant flows into the outdoor heat exchanger 31 and releases heat to the outside atmosphere in the outdoor heat exchanger 31; if the eighth switch valve 37 is opened and the A port and the B port of the fourth three-way valve 39 are connected, the high-temperature and high-pressure gaseous refrigerant flows into the plate heat exchanger 33 and releases heat to the cooling liquid in the plate heat exchanger 33, and the heat-absorbed cooling liquid can be used to heat the vehicle electrical components 32 when the vehicle electrical components 32 include a battery pack, for example, and the heat of the refrigerant can be used to heat the battery pack; if the eighth switch valve 37 is opened and the A port and the C port of the fourth three-way valve 39 are connected, the high-temperature and high-pressure gaseous refrigerant flows into the plate heat exchanger 33 and releases heat to the cooling liquid in the plate heat exchanger 33, and the heat-absorbed cooling liquid can release heat to the outside atmosphere through the radiator 38 when flowing through the radiator 38.

[0127] In addition, for the dehumidification mode, the flow path of the refrigerant is the same as that of the air conditioning system in the refrigeration mode, that is, the low temperature of the air conditioning evaporator 19 cools the high-humidity air in the vehicle passenger compartment, and the condensed water is precipitated to achieve the effect of removing the moisture in the air. After dehumidification by the air conditioning evaporator 19, if temperature compensation is required, the heating fan 40 can be turned on to release heat to the passenger compartment when the refrigerant flows through the air conditioning condenser 16.

[0128] In addition, in the air conditioning system refrigeration mode, if the vehicle refrigerator 2 has a heating requirement, the heating element 28 of the vehicle refrigerator 2 can be turned on to achieve heating of the vehicle refrigerator 2.

[0129] IV. Air conditioning system heating mode

[0130] Referring to FIG. 10, in this mode, the first switch valve 5 is closed, the second air conditioning expansion valve 181 is opened, the second switch valve 6 is closed, at least one of the seventh switch valve 36 and the eighth switch valve 37 is opened, the sixth switch valve 14 is closed, the fifth switch valve 13 is opened, the refrigerator expansion valve 4 is closed, the second check valve 9 is closed, the first air conditioning expansion valve 20 is closed, and the heating fan 40 is opened. In this mode, the compressor 1, the air conditioning condenser 16, the second air conditioning expansion valve 181, and the heat exchange module 3 are connected in series to form a loop.

[0131] The high-temperature and high-pressure gaseous refrigerant flowing out of the outlet of the compressor 1 flows into the air conditioning condenser 16 and releases heat in the air conditioning condenser 16 to raise the temperature of the passenger compartment and achieve air conditioning heating. The refrigerant after releasing heat at the air conditioning condenser 16 flows into the second air conditioning expansion valve 181, is throttled and depressurized by the second air conditioning expansion valve 181, and becomes low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant flows into the heat exchange module 3 and absorbs heat in the heat exchange module 3. The low-temperature and low-pressure gaseous refrigerant flowing out of the outlet of the heat exchange module 3 eventually returns to the compressor 1.

[0132] It should be noted that in this mode, if the seventh switch valve 36 is opened, the low-temperature and low-pressure liquid refrigerant flows into the outdoor heat exchanger 31 and absorbs the heat of the outside atmosphere in the outdoor heat exchanger 31; if the eighth switch valve 37 is opened and the A port and the B port of the fourth three-way valve 39 are connected, the low-temperature and low-pressure liquid refrigerant flows into the plate heat exchanger 33 and absorbs the heat of the cooling liquid in the plate heat exchanger 33, and the cooled cooling liquid can be used to cool the vehicle electrical components 32 when flowing through the vehicle electrical components 32, for example, when the vehicle electrical components 32 include a motor, the cold energy of the refrigerant can be used to cool the motor.

[0133] In addition, for the defogging mode, the flow path of the refrigerant is the same as that of the air conditioning system in the heating mode, and the low-temperature air is heated into high-temperature air when passing through the air conditioning condenser 16, and the high-temperature air is blown to the glass of the vehicle through the defogging channel to remove the fog on the glass.

[0134] In addition, in the air conditioning system heating mode, if the vehicle refrigerator 2 has a refrigeration requirement, the cooling component of the vehicle refrigerator 2 can be opened to realize the refrigeration of the vehicle refrigerator 2.

[0135] Five, synchronous refrigeration mode of vehicle refrigerator and air conditioning system

[0136] Referring to FIG. 11, in this mode, the first switch valve 5 is opened, the second air conditioning expansion valve 181 is closed, the second switch valve 6 is closed, at least one of the seventh switch valve 36 and the eighth switch valve 37 is opened, the refrigerator expansion valve 4 is opened, the first air conditioning expansion valve 20 is opened, the sixth switch valve 14 is opened, the fifth switch valve 13 is closed, and the heating fan 40 is closed. In this mode, the compressor 1, the air conditioning condenser 16, the heat exchange module 3, the refrigerator expansion valve 4, and the refrigerator heat exchanger 21 are connected in series to form a loop, and the compressor, the air conditioning condenser 16, the heat exchange module 3, the first air conditioning expansion valve 20, and the air conditioning evaporator 19 are connected in series to form another loop.

[0137] The high-temperature and high-pressure gaseous refrigerant flowing out of the outlet of the compressor 1 flows into the air conditioner condenser 16. Since the heating fan 40 is closed, i.e. the heating fan 40 does not blow air to the air conditioner condenser 16, the high-temperature and high-pressure gaseous refrigerant does not release heat at the air conditioner condenser 16. The air conditioner condenser 16 is used as a flow passage. The high-temperature and high-pressure gaseous refrigerant flows into the heat exchange module 3 and releases heat in the heat exchange module 3. The refrigerant flowing out of the outlet of the heat exchange module 3 is divided into two paths. One path of the refrigerant is throttled and depressurized by the refrigerator expansion valve 4 to become low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant flows into the refrigerator heat exchanger 21, absorbs heat of the article containing space, and reduces the temperature in the article containing space to achieve the refrigeration or freezing function of the vehicle refrigerator 2. The other path of the refrigerant is throttled and depressurized by the first air conditioner expansion valve 20 to become low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant flows into the air conditioner evaporator 19, absorbs heat of the passenger compartment, and reduces the temperature of the passenger compartment to achieve air conditioning refrigeration. After absorbing heat in the air conditioner evaporator 19 and the refrigerator heat exchanger 21, the refrigerant is finally converged and returns to the compressor 1.

[0138] It should be noted that in this mode, if the seventh switch valve 36 is opened, the high-temperature and high-pressure gaseous refrigerant flows into the outdoor heat exchanger 31 and releases heat to the outside atmosphere in the outdoor heat exchanger 31. If the eighth switch valve 37 is opened and the A port and the B port of the fourth three-way valve 39 are in communication, the high-temperature and high-pressure gaseous refrigerant flows into the plate heat exchanger 33 and releases heat to the cooling liquid in the plate heat exchanger 33. The heat-absorbed cooling liquid can be used to heat the vehicle electrical devices 32 when the vehicle electrical devices 32 flow through the vehicle electrical devices 32. For example, when the vehicle electrical devices 32 include a battery pack, the heat of the refrigerant can be used to heat the battery pack. If the eighth switch valve 37 is opened and the A port and the C port of the fourth three-way valve 39 are in communication, the high-temperature and high-pressure gaseous refrigerant flows into the plate heat exchanger 33 and releases heat to the cooling liquid in the plate heat exchanger 33. The heat-absorbed cooling liquid can be dissipated to the outside atmosphere through the radiator 38 when the cooling liquid flows through the radiator 38.

[0139] Six, synchronous heating mode of vehicle refrigerator and air conditioning system

[0140] Referring to FIG. 12, in this mode, the first switch valve 5 is closed, the second air conditioner expansion valve 181 is opened, the second switch valve 6 is opened, at least one of the seventh switch valve 36 and the eighth switch valve 37 is opened, the sixth switch valve 14 is closed, the fifth switch valve 13 is opened, the refrigerator expansion valve 4 is opened, the second one-way valve 9 is closed, and the first air conditioner expansion valve 20 is closed. In this mode, the compressor 1, the air conditioner condenser 16, the second air conditioner expansion valve 181, and the heat exchange module 3 are sequentially connected in series to form a loop, and the compressor 1, the refrigerator heat exchanger 21, the refrigerator expansion valve 4, and the heat exchange module 3 are sequentially connected in series to form another loop.

[0141] The high-temperature and high-pressure gaseous refrigerant flowing out of the outlet of the compressor 1 is divided into two paths, one of which flows into the air conditioner condenser 16 and releases heat in the air conditioner condenser 16 to raise the temperature of the passenger compartment, thereby realizing air conditioning heating, and the other of which flows into the refrigerator heat exchanger 21 and releases heat in the refrigerator heat exchanger 21 to raise the temperature of the article storage space, thereby realizing the heat preservation or heating function of the vehicle refrigerator 2. The refrigerant that has released heat at the refrigerator heat exchanger 21 flows into the heat exchange module 3 after being throttled and depressurized by the refrigerator expansion valve 4, and the refrigerant that has released heat at the air conditioner condenser 16 flows into the heat exchange module 3 after being throttled and depressurized by the second air conditioner expansion valve 181. The refrigerant absorbs heat in the heat exchange module 3, and the low-temperature and low-pressure gaseous refrigerant flows out of the outlet of the heat exchange module 3 and finally returns to the compressor 1.

[0142] It should be noted that in this mode, if the seventh on-off valve 36 is opened, the low-temperature and low-pressure liquid refrigerant flows into the outdoor heat exchanger 31 and absorbs heat from the atmosphere; if the eighth on-off valve 37 is opened and the A port and the B port of the fourth three-way valve 39 are in communication, the low-temperature and low-pressure liquid refrigerant flows into the plate heat exchanger 33 and absorbs heat from the cooling liquid in the plate heat exchanger 33. The cooled cooling liquid can be used to cool the vehicle electrical components 32 when the vehicle electrical components 32 flow through the vehicle electrical components 32, for example, when the vehicle electrical components 32 include a motor, the cooling capacity of the refrigerant can be used to cool the motor.

[0143] It can be understood that in addition to the above-mentioned modes, based on the specific structure of the vehicle thermal management system 100 provided in the present disclosure, the vehicle thermal management system 100 can also have other thermal management modes, for example, the vehicle electrical components 32 are cooled by the radiator 38.
