[0034] The detailed description of embodiments of the present disclosure will be made hereinafter with reference to the accompanying drawings. It should be understood that the detailed description of embodiments is merely intended to illustrate and explain the present disclosure, and is not intended to limit the present disclosure.

[0035] In the present disclosure, the positional words such as "upstream, downstream" are generally defined with the refrigerant flow direction as the reference, and "inner, outer" refer to the inner and outer of the outline of the corresponding components. In addition, the terms "first", "second", and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0036] In the description of the present disclosure, it also needs to be explained that, unless otherwise explicitly specified and limited, the terms "set", "connected", "connected", "installed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0037] As a first aspect of the present disclosure, as shown in FIG. 1 and FIG. 8, the present disclosure provides a vehicle thermal management system 100, comprising a compressor 14 and a plurality of vehicle refrigerators 22, each vehicle refrigerator 22 comprising a refrigerator heat exchanger 223 for heat exchange with an article containing space of the vehicle refrigerator 22, the plurality of refrigerator heat exchangers 223 are connected in parallel with each other. The outlet of the compressor 14 is connected with the inlet of the plurality of refrigerator heat exchangers 223, and the outlet of the plurality of refrigerator heat exchangers 223 is connected with the inlet of the compressor 14.

[0038] Through the above technical solution, the plurality of vehicle refrigerators 22 each have an independent article containing space, which can increase the storage space in the vehicle and store more articles that require storage at a certain temperature. Moreover, the plurality of vehicle refrigerators 22 can be installed at different positions in the passenger compartment of the vehicle, so as to facilitate users located at different positions in the passenger compartment to take articles in the vehicle refrigerators 22. Since each article containing space is provided with a refrigerator heat exchanger 223, each article containing space can have a different storage temperature to meet the needs of users for different storage temperatures of different foods.

[0039] In addition, the inlet of the plurality of refrigerator heat exchangers 223 is connected with the outlet of the same compressor 14, and the outlet of the plurality of refrigerator heat exchangers 223 is connected with the inlet of the same compressor 14, which can achieve the effects of increasing the storage space of the vehicle and meeting the needs of users for different storage temperatures of different foods as much as possible without increasing the cost of the vehicle and occupying too much volume of the vehicle.

[0040] It needs to be explained here that the above-mentioned refrigerator heat exchanger 223 can be used as an evaporator to cool the air in the article containing space to meet the needs of refrigerating or freezing the articles in the article containing space. The above-mentioned refrigerator heat exchanger 223 can also be used as a condenser to heat the air in the article containing space to heat and keep warm the articles in the article containing space. The present disclosure does not limit whether the refrigerator heat exchanger 223 is used as an evaporator or a condenser, or whether it can be used as an evaporator when there is a need for refrigeration and as a condenser when there is a need for heating.

[0041] In an example embodiment provided by the present disclosure, as shown in FIG. 1, the vehicle thermal management system 100 further comprises a first heat exchanger 15 and a plurality of refrigerator expansion valves 26, which are in one-to-one correspondence with a plurality of refrigerator heat exchangers 223. When refrigeration is performed by the refrigerator heat exchangers 223, the outlet of the compressor 14 is connected to the inlet of the first heat exchanger 15, the outlet of the first heat exchanger 15 is connected to the inlet of the plurality of refrigerator expansion valves 26, and the outlet of each refrigerator expansion valve 26 is connected to the inlet of the corresponding refrigerator heat exchanger 223. The compressor 14, the first heat exchanger 15, the refrigerator expansion valves 26, and the refrigerator heat exchangers 223 can be sequentially connected in series to form a refrigerant circuit. The high-temperature and high-pressure gaseous refrigerant discharged from the compressor 14 flows into the first heat exchanger 15 and releases heat to the atmosphere in the first heat exchanger 15. The refrigerant after heat release is throttled and depressurized by the refrigerator expansion valves 26 to become low-temperature and low-pressure liquid refrigerant, which enters the refrigerator heat exchangers 223 to absorb the temperature of the air in the article storage space in the refrigerator heat exchangers 223, thereby achieving the refrigeration or freezing function of the vehicle refrigerator 22.

[0042] The refrigerator expansion valve 26 described above can control the on-off of the refrigerant flow path in which the refrigerator heat exchanger 223 is located, i.e., control whether the refrigerant flowing out of the first heat exchanger 15 can enter the refrigerator heat exchanger 223 or not, so that the plurality of refrigerator heat exchangers 223 can operate simultaneously or only partially. On the other hand, the refrigerator expansion valve 26 can also adjust the evaporation pressure and evaporation temperature of the refrigerant entering the corresponding refrigerator heat exchanger 223, so that the article storage spaces of the plurality of vehicle refrigerators 22 can have different preservation temperatures.

[0043] In an example embodiment provided by the present disclosure, when heating is performed by the refrigerator heat exchangers 223, the outlet of the compressor 14 is connected to the inlet of the plurality of refrigerator heat exchangers 223, the outlet of each refrigerator heat exchanger 223 is connected to the inlet of the corresponding refrigerator expansion valve 26, the outlet of the plurality of refrigerator expansion valves 26 is connected to the inlet of the first heat exchanger 15, and the outlet of the first heat exchanger 15 is connected to the inlet of the compressor 14. Thus, the refrigerant in the refrigerator heat exchangers 223 can be used to heat the article storage space of the vehicle refrigerator 22, thereby achieving the heating function of the vehicle refrigerator 22.

[0044] To enrich the functions of the vehicle refrigerator 22, as an example, as shown in FIG. 2, the vehicle refrigerator 22 can further comprise a heating element 225 for heating the air in the article storage space. When the refrigerator heat exchanger 223 is used as an evaporator for cooling the article storage space, if the user wants to heat the articles stored in the article storage space, the compressor 14 and the refrigerator heat exchanger 223 can not be started, but the air in the article storage space can be heated by the heating element 225, so that the air in the article storage space can be kept at a certain temperature to heat or keep warm the articles.

[0045] In addition, when the user has a refrigeration demand for one of the plurality of vehicle refrigerators 22 and a heating demand for another vehicle refrigerator 22, the refrigerator heat exchanger 223 corresponding to the one vehicle refrigerator 22 can be operated to refrigerate the article storage space in the one vehicle refrigerator 22, the refrigerator heat exchanger 223 corresponding to the other vehicle refrigerator 22 can be closed, and the heating member 225 corresponding to the other vehicle refrigerator 22 can be turned on, so as to achieve the effect that the one vehicle refrigerator 22 is refrigerated and the other vehicle refrigerator 22 is heated.

[0046] In addition, when the refrigerator heat exchanger 223 is used as a condenser for heating the article storage space, if the user wants to quickly increase the temperature of the article storage space, the refrigerator heat exchanger 223 and the heating member 225 can be simultaneously turned on to increase the temperature increasing speed in the article storage space.

[0047] As another implementation, the vehicle refrigerator 22 can further include a cooling member for cooling air in the article storage space. When the refrigerator heat exchanger 223 is used as a condenser for heating the article storage space, if the user wants to cool the articles stored in the article storage space, the compressor 14 and the refrigerator heat exchanger 223 can not be started, and the cooling member can be used to cool the air in the article storage space, so as to refrigerate or freeze the articles.

[0048] In addition, when the user has a refrigeration demand for one of the plurality of vehicle refrigerators 22 and a heating demand for another vehicle refrigerator 22, the refrigerator heat exchanger 223 corresponding to the one vehicle refrigerator 22 can be operated to refrigerate the article storage space in the one vehicle refrigerator 22, the refrigerator heat exchanger 223 corresponding to the other vehicle refrigerator 22 can be closed, and the heating member 225 corresponding to the other vehicle refrigerator 22 can be turned on, so as to achieve the effect that the one vehicle refrigerator 22 is refrigerated and the other vehicle refrigerator 22 is heated.

[0049] In addition, when the refrigerator heat exchanger 223 is used as a condenser for heating the article storage space, if the user wants to quickly increase the temperature of the article storage space, the refrigerator heat exchanger 223 and the heating member 225 can be simultaneously turned on to increase the temperature increasing speed in the article storage space.

[0050] In order to improve the heat exchange effect between the refrigerator heat exchanger 223 and the air in the article storage space, optionally, as shown in FIG. 8, the refrigerator heat exchanger 223 includes a heat exchange pipe 221 and a heat exchange shell 222, the inner surface of the heat exchange shell 222 defines the article storage space, the outlet of the compressor 14 is connected with the inlet of the heat exchange pipe 221, the outlet of the heat exchange pipe 221 is connected with the inlet of the compressor 14, and the heat exchange pipe 221 is in heat conduction contact with the outer surface of the heat exchange shell 222, so that the refrigerant in the heat exchange pipe 221 can directly exchange heat with the air in the article storage space through the heat exchange shell 222.

[0051] The inlet and outlet of the compressor 14 are connected with the outlet and inlet of the heat exchange pipe 221, and the heat exchange pipe 221 can be provided with the refrigerant for heat exchange. The heat exchange pipe 221 is in heat conduction contact with the outer surface of the heat exchange shell 222, and the inner surface of the heat exchange shell 222 defines an article containing space. The heat exchange shell 222 can be directly in contact with the air in the article containing space, so that the cold or heat of the refrigerant in the heat exchange pipe 221 can be directly conducted to the heat exchange shell 222 through the heat exchange pipe 221, and heat exchange with the air in the article containing space through the heat exchange shell 222, reducing the loss of cold or heat in the conduction process, and improving the refrigeration or heating efficiency of the vehicle-mounted refrigerator 22.

[0052] Optionally, the heat conduction coefficient of the heat exchange shell 222 can be 201 W / mk-237 W / mk. The material with this coefficient has good heat conduction performance and can meet the heat exchange demand of the heat exchange pipe 221 for heat exchange with the air in the article containing space through the heat exchange shell 222.

[0053] The specific material of the heat exchange shell 222 is not limited in the present disclosure, for example, the material of the heat exchange shell 222 can be aluminum or copper.

[0054] As mentioned above, the vehicle-mounted refrigerator 22 can include a heating element 225, as shown in FIG. 8, in an embodiment provided by the present disclosure, the heating element 225 can include a heating film, and the heating film is covered on the outer surface of the heat exchange shell 222 and / or the side of the heat exchange pipe 221 away from the heat exchange shell 222.

[0055] For the above-mentioned embodiment of the vehicle-mounted refrigerator 22 including a cooling element, the cooling element can include a semiconductor refrigeration sheet, and the semiconductor refrigeration sheet is covered on the outer surface of the heat exchange shell 222 and / or the side of the heat exchange pipe 221 away from the heat exchange shell 222.

[0056] The heating film or semiconductor refrigeration sheet covered on the outer surface of the heat exchange shell 222 can directly exchange heat with the heat exchange shell 222, and exchange heat with the air in the article containing space through the heat exchange shell 222, reducing the heat loss in the heating or refrigeration process.

[0057] The heating film or semiconductor refrigeration sheet covered on the side of the heat exchange pipe 221 away from the heat exchange shell 222 can not only exchange heat with the air in the article containing space through the heat exchange pipe 221 and the heat exchange shell 222, but also can press the heat exchange pipe 221 against the heat exchange shell 222, to ensure the heat conduction contact between the heat exchange pipe 221 and the heat exchange shell 222.

[0058] To further improve the heat exchange efficiency, the vehicle refrigerator 22 can optionally comprise a fan 224, as shown in FIG. 1, which is configured to accelerate the airflow in the article containing space. For example, the fan 224 is configured to generate airflow that can exchange heat with the refrigerant in the heat exchange pipe 221 and enter the article containing space. The fan 224 can accelerate the flow between the air near the heat exchange pipe 221 and the air in the article containing space, thereby improving the heat exchange efficiency between the heat exchange pipe 221 and the air in the article containing space, and improving the heating or cooling speed of the vehicle refrigerator 22. It can be understood that when the heating element 225 is heated or the cooling element is cooled, the fan 224 can accelerate the flow between the air near the heating element 225 or the cooling element and the air in the article containing space, thereby improving the heat exchange efficiency between the heating element 225 or the cooling element and the air in the article containing space, and improving the heating or cooling speed of the vehicle refrigerator 22.

[0059] Optionally, the heat exchange shell 222 is provided with an air inlet, and the fan 224 is arranged at the air inlet. The air inlet is arranged on the heat exchange shell 222 to accommodate the fan 224, so that the fan 224 does not occupy the volume of the article containing space. At the same time, the air inlet also enables the fan 224 to directly drive the air on both sides of the air inlet to flow relative to each other, forming a convection, thereby improving the heat exchange efficiency of the heat exchange pipe 221.

[0060] As shown in FIG. 1, the vehicle thermal management system 100 can further comprise an air conditioning system 1, which comprises the above-mentioned compressor 14. In other words, the compressor 14 connected to the refrigerator heat exchanger 223 of the plurality of vehicle refrigerators 22 is the compressor 14 of the air conditioning system 1, that is, the compressor 14 not only plays a role of compressing and driving the refrigerant in the refrigerant flow path where the devices (such as air conditioning evaporator, air conditioning condenser, etc.) of the air conditioning system 1 are located, but also plays a role of compressing and driving the refrigerant in the refrigerant flow path where the plurality of refrigerator heat exchangers 223 of the plurality of vehicle refrigerators 22 are located, achieving the effect of using the same compressor 14 to provide refrigerant for different thermal management devices.

[0061] Using the compressor 14 in the air conditioning system 1 to provide flowing refrigerant for the refrigerator heat exchanger 223 of the plurality of vehicle refrigerators 22 can also improve the utilization rate of the compressor 14, improve the integration of the vehicle thermal management system 100, reduce the number of devices required by the plurality of vehicle refrigerators 22, and avoid a significant increase in cost due to the arrangement of the plurality of vehicle refrigerators 22.

[0062] Optionally, the air conditioning system 1 can further comprise the above-mentioned first heat exchanger 15, that is, the first heat exchanger 15 connected to the refrigerator heat exchanger 223 of the plurality of vehicle refrigerators 22 is the first heat exchanger 15 of the air conditioning system 1.

[0063] Optionally, as shown in FIG. 1, the air conditioning system 1 further comprises a second heat exchanger 12 and an air conditioning expansion valve 16, the second heat exchanger 12 is connected with the plurality of refrigerator heat exchangers 223 in parallel, the outlet of the compressor 14 is further connected with the inlet of the second heat exchanger 12 via the air conditioning expansion valve 16, and the outlet of the second heat exchanger 12 is connected with the inlet of the compressor 14.

[0064] The compressor 14, the first heat exchanger 15, the air conditioning expansion valve 16, and the second heat exchanger 12 can be connected in series to form a refrigeration circuit, so that the second heat exchanger 12 can absorb heat from the passenger compartment as an evaporator to realize the refrigeration function of the air conditioning system 1. In addition, the second heat exchanger 12 is connected with the plurality of refrigerator heat exchangers 223 in parallel, so that the vehicle refrigerator 22 and the air conditioning system 1 can be operated simultaneously to meet the user's need for simultaneous refrigeration of the passenger compartment and the vehicle refrigerator 22.

[0065] Optionally, as shown in FIG. 1, the air conditioning system 1 further comprises a gas-liquid separator 17, the inlet of the gas-liquid separator 17 is connected with the outlets of the plurality of refrigerator heat exchangers 223 and the second heat exchanger 12, and the outlet of the gas-liquid separator 17 is connected with the inlet of the compressor 14. The refrigerant flowing out of the outlets of the refrigerator heat exchangers 223 and the second heat exchanger 12 is separated into liquid and gas in the gas-liquid separator 17 before returning to the compressor 14, so that the gas refrigerant returns to the compressor 14 to prevent damage to the compressor 14.

[0066] In order to further improve the refrigeration effect of the vehicle refrigerator 22, optionally, as shown in FIG. 1, the vehicle thermal management system 100 further comprises a pressure regulating structure 3, the inlet of the pressure regulating structure 3 is connected with the outlet of the second heat exchanger 12, and the outlet of the pressure regulating structure 3 is connected with the inlet of the compressor 14. The pressure regulating structure 3 has a first conduction state, in which the refrigerant pressure on the inlet side of the pressure regulating structure 3 is different from the refrigerant pressure on the outlet side of the pressure regulating structure 3, so that the refrigerant pressure in the second heat exchanger 12 can be different from the refrigerant pressure in the refrigerator heat exchanger 223.

[0067] Since the inlet of the pressure regulating structure 3 is connected with the outlet of the second heat exchanger 12, the refrigerant pressure at the inlet of the pressure regulating structure 3 is equal to or substantially equal to the refrigerant pressure in the second heat exchanger 12, and since the second heat exchanger 12 is connected with the refrigerator heat exchanger 223 in parallel, the outlet of the pressure regulating structure 3 is in communication with the outlet of the refrigerator heat exchanger 223, and the refrigerant pressure at the outlet of the pressure regulating structure 3 is equal to or substantially equal to the refrigerant pressure at the outlet of the refrigerator heat exchanger 223.

[0068] The refrigerant pressure in the heat exchanger (i.e., the refrigerant evaporation pressure) is positively correlated with the refrigerant evaporation temperature, that is, the smaller the refrigerant pressure, the lower the refrigerant evaporation temperature. By adjusting the refrigerant pressure at the inlet side and the outlet side of the pressure regulating structure 3, the refrigerant pressure in the second heat exchanger 12 and the refrigerant pressure in the refrigerator heat exchanger 223 can be adjusted, so that the refrigerant pressure in the second heat exchanger 12 and the refrigerant pressure in the refrigerator heat exchanger 223 are different, so that the refrigerant evaporation temperatures in the refrigerator heat exchanger 223 and the second heat exchanger 12 are different, so that the second heat exchanger 12 and the refrigerator heat exchanger 223 can have different cooling speeds to meet the different temperature requirements of the user for the temperature in the passenger compartment and the temperature in the vehicle refrigerator 22 when the vehicle refrigerator 22 and the air conditioning system 1 are used at the same time.

[0069] Optionally, as shown in FIG. 1, in the first conduction state, the refrigerant pressure at the inlet side of the pressure regulating structure 3 is greater than the refrigerant pressure at the outlet side of the pressure regulating structure 3, so that the refrigerant pressure in the second heat exchanger 12 is greater than the refrigerant pressure in the refrigerator heat exchanger 223. Since in the first conduction state, the refrigerant pressure in the second heat exchanger 12 is greater than the refrigerant pressure in the refrigerator heat exchanger 223, so that the refrigerant evaporation temperature in the second heat exchanger 12 is greater than the refrigerant evaporation temperature in the refrigerator heat exchanger 223, that is, in the case of normal operation of the air conditioning system 1, the refrigeration temperature of the vehicle refrigerator 22 is lower than the refrigeration temperature of the air conditioning system 1, so that the demand for lower refrigeration temperature of the vehicle refrigerator 22 can be met, and the refrigeration capacity and refrigeration speed of the vehicle refrigerator 22 are improved in the case of the second heat exchanger 12 and the refrigerator heat exchanger 223 sharing the compressor 14 and the second heat exchanger 12 and the refrigerator heat exchanger 223 refrigerating at the same time.

[0070] Optionally, the pressure regulating structure 3 also has a second conduction state, in which the refrigerant pressure at the inlet side of the pressure regulating structure 3 is the same as the refrigerant pressure at the outlet side of the pressure regulating structure 3. In the second conduction state, the refrigerant pressure at the inlet and outlet of the pressure regulating structure 3 is the same, and the pressure regulating structure 3 can be regarded as a flow-through pipe, at this time, the refrigerant pressure in the parallel-connected second heat exchanger 12 and the refrigerator heat exchanger 223 is the same, and the refrigerant evaporation temperature is also the same.

[0071] When the vehicle refrigerator 22 has high demand and the air conditioner has low demand, the pressure regulating structure 3 can be in the first conduction state to preferentially meet the refrigeration demand of the vehicle refrigerator 22; when the vehicle refrigerator 22 has low demand and the air conditioner has high demand, the pressure regulating structure 3 can be in the second conduction state to preferentially meet the refrigeration demand of the air conditioning system 1.

[0072] The specific structure of the pressure regulating structure 3 is not limited in the present disclosure, and in an embodiment provided by the present disclosure, the pressure regulating structure 3 can be a throttle valve. The throttle valve can adjust the amount of refrigerant passing through the throttle valve by adjusting the opening degree of the throttle valve, so that the refrigerant pressures on the inlet side and the outlet side of the throttle valve are different. In other embodiments, the pressure regulating structure 3 can also be a pressure regulating valve, a flow regulating valve, etc.

[0073] Optionally, in the first conduction state, the absolute value of the difference between the refrigerant pressure on the inlet side of the pressure regulating structure 3 and the refrigerant pressure on the outlet side of the pressure regulating structure 3 is 150-200 kPa. When the difference in refrigerant pressure is within this range, the refrigeration temperature of the vehicle refrigerator 22 can be as low as possible while ensuring the normal operation of the air conditioning system 1, thereby meeting the refrigeration needs of the vehicle refrigerator 22.

[0074] In order to improve the intelligent degree of the vehicle thermal management system 100, the air conditioning system 1 optionally further comprises a first temperature and pressure sensor 13, which is located downstream of the second heat exchanger 12 and upstream of the pressure regulating structure 3. The vehicle thermal management system 100 further comprises a second temperature and pressure sensor 25, and each refrigerator heat exchanger 223 is provided with a second temperature and pressure sensor 25 downstream. The vehicle thermal management system 100 further comprises a controller, and the first temperature and pressure sensor 13, the second temperature and pressure sensor 25, and the pressure regulating structure 3 are electrically connected to the controller.

[0075] The first temperature and pressure sensor 13 can detect the refrigerant pressure and temperature in the second heat exchanger 12, and the second temperature and pressure sensor 25 can detect the refrigerant pressure and temperature in the refrigerator heat exchanger 223, and transmit the measured pressure and temperature information to the controller. The controller can adjust the difference between the refrigerant pressure on the inlet side of the pressure regulating structure 3 and the refrigerant pressure on the outlet side of the pressure regulating structure 3 according to the obtained pressure and temperature data, so that the air conditioning system 1 and the plurality of vehicle refrigerators 22 can operate at the refrigeration temperature required by the user.

[0076] As a second aspect of the present disclosure, as shown in FIGS. 1-8, the present disclosure provides a vehicle thermal management system 100, comprising a plurality of vehicle refrigerators 22, each vehicle refrigerator 22 having an article containing space. Wherein the vehicle thermal management system 100 has a first working mode, in the first working mode, one of the plurality of vehicle refrigerators 22 can heat its article containing space, and another of the plurality of vehicle refrigerators 22 can cool its article containing space.

[0077] By the above technical solution, the plurality of vehicle refrigerators 22 each has an independent article storage space, which can increase the storage space in the vehicle and store more articles that require a storage temperature. In addition, the plurality of vehicle refrigerators 22 can be installed at different positions in the passenger compartment of the vehicle, so as to facilitate users at different positions in the passenger compartment to take articles in the vehicle refrigerators 22. In addition, in the first working mode of the vehicle thermal management system 100, one of the plurality of vehicle refrigerators 22 can heat its article storage space, heat or keep warm the articles in the article storage space, and another of the plurality of vehicle refrigerators 22 can cool its article storage space, refrigerate or freeze the articles in the article storage space. In this way, each article storage space can have a different storage temperature to meet the needs of users for different storage temperatures of different foods.

[0078] The vehicle refrigerator 22 described above can heat or cool its article storage space by the refrigerant flowing through the vehicle refrigerator 22, or by the heating member 225 or the cooling member, or one of the plurality of vehicle refrigerators 22 can heat or cool its article storage space by the refrigerant flowing through the vehicle refrigerator 22, and another of the plurality of vehicle refrigerators 22 can cool or heat its article storage space by the cooling member or the heating member 225, which is not limited in the present disclosure.

[0079] For example, in an embodiment provided by the present disclosure, one of the plurality of vehicle refrigerators 22 has a heating member 225 for heating the article storage space of the vehicle refrigerator 22, and another of the plurality of vehicle refrigerators 22 has a cooling member for cooling the article storage space of the vehicle refrigerator 22. In the first working mode, the heating member 225 on one of the plurality of vehicle refrigerators 22 can heat the article storage space of the vehicle refrigerator 22, and the cooling member on another of the plurality of vehicle refrigerators 22 can cool the article storage space of the vehicle refrigerator 22.

[0080] In other embodiments provided by the present disclosure, the first working mode can also be achieved by heat exchange between the refrigerant and the article storage space of the vehicle refrigerator 22. For example, in an embodiment provided by the present disclosure, as shown in FIG. 2, the plurality of vehicle refrigerators 22 include a first vehicle refrigerator 226 and a second vehicle refrigerator 227, and the vehicle thermal management system 100 includes the compressor 14, and the compressor 14, the first vehicle refrigerator 226 and the second vehicle refrigerator 227 can be connected in series to form a loop. In the first working mode, the refrigerant flowing through the first vehicle refrigerator 226 can heat the article storage space of the first vehicle refrigerator 226, and the refrigerant flowing through the second vehicle refrigerator 227 can cool the article storage space of the second vehicle refrigerator 227.

[0081] The refrigerant discharged by the compressor 14 can flow into the first vehicle refrigerator 226 and release heat to the article storage space of the first vehicle refrigerator 226 to raise the temperature of the article storage space of the first vehicle refrigerator 226, thereby achieving heating or heat preservation of the articles. The refrigerant released heat in the first vehicle refrigerator 226 enters the second vehicle refrigerator 227 and absorbs the heat of the article storage space of the second vehicle refrigerator 227 to lower the temperature of the article storage space of the second vehicle refrigerator 227, thereby achieving refrigeration or freezing of the articles.

[0082] The first vehicle refrigerator 226 and the second vehicle refrigerator 227 are connected to the same compressor 14, which can increase the storage space of the vehicle and meet the needs of users for different storage temperatures of different foods as much as possible without increasing the cost of the vehicle and occupying too much space of the vehicle.

[0083] Optionally, the compressor 14 can be the compressor 14 of the air conditioning system 1, so that the plurality of vehicle refrigerators 22 and the air conditioning system 1 share the compressor 14, further reducing the cost and the occupation of the space of the vehicle caused by the plurality of vehicle refrigerators 22.

[0084] It can be understood that, in order to enable the refrigerant to flow into the vehicle refrigerator 22 and exchange heat with the article storage space in the vehicle refrigerator 22, the vehicle refrigerator 22 has a passage for the refrigerant to flow through. For example, the vehicle refrigerator 22 can be provided with a refrigerant heat exchange channel, or the vehicle refrigerator 22 can be provided with a refrigerant heat exchange chamber, or the vehicle refrigerator 22 can be provided with a refrigerant heat exchange pipeline 221, or the vehicle refrigerator 22 can be provided with a heat exchanger (for example, the refrigerator heat exchanger 223 mentioned below). The present disclosure does not limit how the refrigerant specifically exchanges heat with the article storage space in the vehicle refrigerator 22, as long as the refrigerant can flow into the vehicle refrigerator 22 and exchange heat with the article storage space in the vehicle refrigerator 22.

[0085] Optionally, the vehicle thermal management system 100 further comprises a refrigerator expansion valve 26, the compressor 14, the first vehicle refrigerator 226, the refrigerator expansion valve 26 and the second vehicle refrigerator 227 can be connected in series to form a loop. In this way, the refrigerant that releases heat in the first vehicle refrigerator 226 can be throttled and decompressed by the refrigerator expansion valve 26 to become low-temperature and low-pressure liquid refrigerant, and the liquid refrigerant enters the second vehicle refrigerator 227 and absorbs the heat of the article containing space of the second vehicle refrigerator 227. The refrigerator expansion valve 26 can adjust the evaporation pressure and evaporation temperature of the refrigerant entering the second vehicle refrigerator 227, so that the temperature of the second vehicle refrigerator 227 can be used to store refrigerated goods or frozen goods.

[0086] Optionally, the first vehicle refrigerator 226 has a cooling device for cooling the article containing space of the first vehicle refrigerator 226, and / or the second vehicle refrigerator 227 has a heating device 225 for heating the article containing space of the vehicle refrigerator 22. The vehicle thermal management system 100 further has a second working mode, in which the cooling device cools the article containing space of the first vehicle refrigerator 226, and / or the heating device 225 heats the article containing space of the second vehicle refrigerator 227.

[0087] When the user only has a use demand for the first vehicle refrigerator 226 and needs to refrigerate or freeze the articles, the cooling device can be turned on to cool the article containing space of the first vehicle refrigerator 226, at this time the compressor 14 does not provide refrigerant to the first vehicle refrigerator 226 and the second vehicle refrigerator 227. When the user only has a use demand for the second vehicle refrigerator 227 and needs to heat or keep warm the articles, the heating device 225 can be turned on to heat the article containing space of the second vehicle refrigerator 227, at this time the compressor 14 does not provide refrigerant to the first vehicle refrigerator 226 and the second vehicle refrigerator 227. Since the specific positions of the first vehicle refrigerator 226 and the second vehicle refrigerator 227 on the vehicle can be different, if the user needs the first vehicle refrigerator 226 to refrigerate or freeze the articles and needs the second vehicle refrigerator 227 to heat or keep warm the articles, the cooling device and the heating device 225 can be turned on, at this time the refrigerant does not flow through the first vehicle refrigerator 226 and the second vehicle refrigerator 227.

[0088] In other embodiments provided in the present disclosure, one of the plurality of vehicle refrigerators 22 can be heated or cooled by the refrigerant flowing through the vehicle refrigerator 22 to cool or heat the article containing space thereof, and another of the plurality of vehicle refrigerators 22 can be cooled or heated by the cooling device or the heating device 225 to cool or heat the article containing space thereof, thereby realizing the first working mode described above. In this embodiment, at least two of the plurality of vehicle refrigerators 22 can be connected in parallel to each other, and at least two of the plurality of vehicle refrigerators 22 can also be connected in series to each other, which is not limited in the present disclosure.

[0089] For example, in one embodiment provided by the present disclosure, as shown in FIG. 3 and FIG. 1, the vehicle thermal management system 100 can comprise a compressor 14, at least two of the plurality of vehicle refrigerators 22 are connected in parallel with each other, an outlet of the compressor 14 is connected to refrigerant inlets of the at least two vehicle refrigerators 22, and the outlet of the compressor 14 is capable of being selectively connected or disconnected to the refrigerant inlet of each of the at least two vehicle refrigerators 22, and refrigerant outlets of the at least two vehicle refrigerators 22 are connected to an inlet of the compressor 14. The at least two vehicle refrigerators 22 are provided with heating elements 225 for heating the article storage spaces. In a first working mode, refrigerant can flow through one of the at least two vehicle refrigerators 22 and cool the article storage space of the vehicle refrigerator 22, and the heating element 225 on the other of the at least two vehicle refrigerators 22 can heat the article storage space of the vehicle refrigerator 22.

[0090] Since the outlet of the compressor 14 is capable of being selectively connected or disconnected to the refrigerant inlet of each of the at least two vehicle refrigerators 22, the refrigerant flowing out of the compressor 14 can be selectively introduced into any one of the plurality of vehicle refrigerators 22 connected in parallel with each other to exchange heat with the article storage space of the vehicle refrigerator 22, and thus, in the above-mentioned first working mode, the compressor 14 can be connected to one of the vehicle refrigerators 22 connected in parallel with each other, while being disconnected from the other of the vehicle refrigerators 22 connected in parallel with each other, so that one of the at least two vehicle refrigerators 22 is cooled by the refrigerant, and the other of the at least two vehicle refrigerators 22 is heated by the heating element 225. Here, the selective connection or disconnection of the outlet of the compressor 14 to the refrigerant inlet of each of the at least two vehicle refrigerators 22 can be achieved by a switching valve, a on-off valve, or a refrigerator expansion valve 26 mentioned below, which is not limited in the present disclosure.

[0091] In addition, the refrigerant inlets of the at least two vehicle refrigerators 22 are connected to the outlet of the same compressor 14, and the refrigerant outlets of the at least two vehicle refrigerators 22 are connected to the inlet of the same compressor 14, which can achieve the effects of increasing the storage space of the vehicle and meeting the needs of users for different storage temperatures of different foods as much as possible without increasing the cost of the vehicle and occupying too much volume of the vehicle. Optionally, the above-mentioned compressor 14 can be the compressor 14 of the air conditioning system 1, so that the at least two vehicle refrigerators 22 can share the compressor 14 with the air conditioning system 1.

[0092] Optionally, each of the vehicle refrigerators 22 comprises a refrigerator heat exchanger 223 for exchanging heat with the article storage space of the vehicle refrigerator 22, the refrigerator heat exchangers 223 of the at least two vehicle refrigerators 22 are connected in parallel with each other, the outlet of the compressor 14 is connected to the inlet of the refrigerator heat exchangers 223 of the at least two vehicle refrigerators 22, and the outlet of the refrigerator heat exchangers 223 of the at least two vehicle refrigerators 22 is connected to the inlet of the compressor 14.

[0093] Optionally, the vehicle refrigerator 22 can also have a cooling element for cooling the article storage space. On the one hand, the article storage space can be cooled by the cooling element instead of the refrigerant, thereby providing a variety of options for means of cooling the article storage space, and on the other hand, when the vehicle refrigerator 22 cools the article storage space by the refrigerant flowing therethrough, the cooling element can also be turned on to improve the cooling efficiency of the article storage space.

[0094] Optionally, the vehicle thermal management system 100 can also have a third working mode, in which the refrigerant can flow through at least two vehicle refrigerators 22 connected in parallel with each other and cool the article storage spaces of the at least two vehicle refrigerators 22. When the user has a refrigeration demand for at least two vehicle refrigerators 22 of the plurality of vehicle refrigerators 22, the vehicle thermal management system 100 can be in the third working mode, and the outlet of the compressor 14 can be connected to the at least two vehicle refrigerators 22, so as to cool the at least two vehicle refrigerators 22 by the refrigerant.

[0095] In the above-mentioned third working mode, the refrigerant can flow through at least two vehicle refrigerators 22 connected in parallel with each other and cool the article storage spaces of the at least two vehicle refrigerators 22 to different temperatures, so as to meet the user's demand for different article cooling temperatures of different vehicle refrigerators 22. For example, the refrigerant in one of the at least two vehicle refrigerators 22 connected in parallel with each other can cool the article storage space of the vehicle refrigerator 22 to a refrigeration temperature, so that the user can use the vehicle refrigerator 22 to refrigerate articles, and the refrigerant in another of the at least two vehicle refrigerators 22 connected in parallel with each other can cool the article storage space of the vehicle refrigerator 22 to a freezing temperature, so that the user can use the vehicle refrigerator 22 to freeze articles.

[0096] Optionally, the vehicle thermal management system 100 can further have a fourth working mode, in which the heating element 225 on at least two of the plurality of vehicle refrigerators 22 can heat the article storage space of the at least two vehicle refrigerators 22. When the user has a heating demand for at least two of the plurality of vehicle refrigerators 22, the vehicle thermal management system 100 can be in the fourth working mode, in which the outlet of the compressor 14 is not connected to the at least two vehicle refrigerators 22, and the at least two vehicle refrigerators 22 heat the article storage space by the heating element 225.

[0097] In the fourth working mode described above, the heating element 225 on at least two of the plurality of vehicle refrigerators 22 heats the article storage space of the at least two vehicle refrigerators 22 to different temperatures to meet the user's demand for different article heating temperatures of different vehicle refrigerators 22. For example, the refrigerant in one of the plurality of vehicle refrigerators 22 can heat the article storage space of the vehicle refrigerator 22 to a temperature for keeping warm, so that the user can use the vehicle refrigerator 22 to keep the articles warm, and the refrigerant in another of the plurality of vehicle refrigerators 22 can heat the article storage space of the vehicle refrigerator 22 to a temperature for heating, so that the user can use the vehicle refrigerator 22 to heat the articles.

[0098] Optionally, as shown in FIG. 3 and FIG. 1, the vehicle thermal management system 100 further comprises a first heat exchanger 15 and at least two refrigerator expansion valves 26, which correspond to the at least two vehicle refrigerators 22 one by one. The outlet of the compressor 14 is connected to the inlet of the first heat exchanger 15, the outlet of the first heat exchanger 15 is connected to the inlet of the at least two refrigerator expansion valves 26, and the outlet of each refrigerator expansion valve 26 is connected to the refrigerant inlet of the corresponding vehicle refrigerator 22. The compressor 14, the first heat exchanger 15, the refrigerator expansion valves 26, and the vehicle refrigerators 22 can be connected in series to form a refrigerant circuit, the high-temperature and high-pressure gaseous refrigerant discharged from the compressor 14 flows into the first heat exchanger 15 and releases heat in the first heat exchanger 15, the refrigerant after heat release is throttled and decompressed by the refrigerator expansion valves 26 to become low-temperature and low-pressure liquid refrigerant, which enters the vehicle refrigerators 22, thereby absorbing the temperature of the air in the article storage space in the vehicle refrigerators 22 to realize the refrigeration or freezing function of the vehicle refrigerators 22.

[0099] The refrigerator expansion valve 26 described above can control the on-off of the refrigerant flow path where the vehicle refrigerator 22 is located, that is, control whether the refrigerant flowing out of the outlet of the first heat exchanger 15 can enter the vehicle refrigerator 22 or not, so that the plurality of vehicle refrigerators 22 can be operated simultaneously or only partially, and on the other hand, the refrigerator expansion valve 26 can also adjust the evaporation pressure and evaporation temperature of the refrigerant entering the corresponding vehicle refrigerator 22, so that the article storage spaces of the plurality of vehicle refrigerators 22 can have different preservation temperatures.

[0100] Optionally, the first heat exchanger 15 can be a heat exchanger of the air conditioning system 1, for example, an outdoor heat exchanger of the air conditioning system 1.

[0101] It can be understood that, for the case that the vehicle refrigerator 22 comprises a refrigerator heat exchanger 223, the at least two refrigerator expansion valves 26 correspond to the at least two vehicle refrigerators 22 one by one, the outlet of the compressor 14 is connected to the inlet of the first heat exchanger 15, the outlet of the first heat exchanger 15 is connected to the inlet of the refrigerator expansion valve 26, and the outlet of the refrigerator expansion valve 26 is connected to the inlet of the refrigerator heat exchanger 223. The compressor 14, the first heat exchanger 15, the refrigerator expansion valve 26, and the refrigerator heat exchanger 223 can be sequentially connected in series to form a refrigerant circuit.

[0102] Optionally, as shown in FIG. 1, the vehicle thermal management system 100 further comprises a second heat exchanger 12, the second heat exchanger 12 is connected in parallel to the at least two vehicle refrigerators 22, the outlet of the first heat exchanger 15 is further connected to the inlet of the second heat exchanger 12, and the outlet of the first heat exchanger 15 can be selectively connected or disconnected to the inlet of the second heat exchanger 12, and the outlet of the second heat exchanger 12 is connected to the inlet of the compressor 14. In other words, the compressor 14, the first heat exchanger 15, and the second heat exchanger 12 can also be sequentially connected in series to form a circuit.

[0103] Since the outlet of the first heat exchanger 15 can be selectively connected or disconnected to the inlet of the second heat exchanger 12, and the outlet of the first heat exchanger 15 is connected to the inlet of the at least two refrigerator expansion valves 26, the refrigerant flowing out of the outlet of the first heat exchanger 15 can be selected to enter the second heat exchanger 12 or the refrigerator expansion valve 26, and when the refrigerant flowing out of the outlet of the first heat exchanger 15 enters the second heat exchanger 12, the refrigerant absorbs heat in the second heat exchanger 12. That is, the above-mentioned thermal management system can realize a mode of refrigeration of the vehicle refrigerator 22, a mode of refrigeration of the second heat exchanger 12, and a mode of refrigeration of the vehicle refrigerator 22 and the second heat exchanger 12 at the same time.

[0104] Optionally, the second heat exchanger 12 can be an evaporator in the air conditioning system 1, which is used to absorb heat of the passenger compartment to achieve refrigeration of the passenger compartment. Since the second heat exchanger 12 is connected in parallel to the at least two vehicle refrigerators 22, the vehicle refrigerator 22 and the air conditioning system 1 can be operated at the same time, which meets the needs of users for refrigeration of the passenger compartment and the vehicle refrigerator 22 at the same time. The second heat exchanger 12 can also be a heat exchanger in a battery thermal management system, which is used to cool the battery pack. The second heat exchanger 12 can also be arranged in an electric drive system, so that the refrigerant can provide cold energy to the cooling liquid in the electric drive system through the second heat exchanger 12 to cool the battery pack, the motor, the motor controller, and other devices that have cooling needs.

[0105] Optionally, as shown in FIG. 1, for the embodiment in which the second heat exchanger 12 is an evaporator in the air conditioning system 1, the air conditioning system 1 can comprise an air conditioning expansion valve 16, the outlet of the compressor 14 is connected to the inlet of the second heat exchanger 12 via the air conditioning expansion valve 16. The air conditioning expansion valve 16 can be used to control the selective conduction or cut-off of the outlet of the first heat exchanger 15 to the inlet of the second heat exchanger 12, and to adjust the evaporation pressure and evaporation temperature of the refrigerant entering the second heat exchanger 12, so as to adjust the refrigeration temperature of the passenger compartment.

[0106] Optionally, as shown in FIG. 4, the air conditioning system 1 can further comprise a gas-liquid separator 17, the inlet of the gas-liquid separator 17 is connected to the outlet of the at least two vehicle refrigerators 22 and the outlet of the second heat exchanger 12, and the outlet of the gas-liquid separator 17 is connected to the inlet of the compressor 14. The refrigerant flowing out of the vehicle refrigerator 22 and the outlet of the second heat exchanger 12 is separated into gas and liquid in the gas-liquid separator 17 before returning to the compressor 14, so that the gas refrigerant returns to the compressor 14 to prevent damage to the compressor 14.

[0107] Optionally, referring to FIG. 4, the vehicle thermal management system 100 can further comprise a pressure regulating structure 3, the pressure regulating structure 3 is arranged downstream of the second heat exchanger 12, or the pressure regulating structure 3 is arranged downstream of at least one of the vehicle refrigerators 22 connected in parallel with each other.

[0108] The pressure regulating structure 3 has a first conduction state, in which the refrigerant pressure on the inlet side of the pressure regulating structure 3 is different from the refrigerant pressure on the outlet side of the pressure regulating structure 3, so that the refrigerant pressure in the second heat exchanger 12 is different from the refrigerant pressure in the vehicle refrigerator 22.

[0109] It should be noted that the pressure regulating structure 3 arranged downstream of at least one of the vehicle refrigerators 22 connected in parallel with each other means that the pressure regulating structure 3 can be arranged downstream of each of the vehicle refrigerators 22 connected in parallel with each other, or the pressure regulating structure 3 can be arranged downstream of any one of the vehicle refrigerators 22 connected in parallel with each other, or the pressure regulating structure 3 can be arranged downstream of at least two of the vehicle refrigerators 22 connected in parallel with each other.

[0110] For the embodiment in which the inlet of the pressure regulating structure 3 is connected with the outlet of the second heat exchanger 12 (i.e. the pressure regulating structure 3 is arranged downstream of the second heat exchanger 12), the refrigerant pressure at the inlet of the pressure regulating structure 3 is equal to or substantially equal to the refrigerant pressure in the second heat exchanger 12, and since the second heat exchanger 12 is in parallel with the vehicle refrigerator 22, the outlet of the pressure regulating structure 3 is in communication with the outlet of the vehicle refrigerator 22, and the refrigerant pressure at the outlet of the pressure regulating structure 3 is equal to or substantially equal to the refrigerant pressure at the outlet of the vehicle refrigerator 22.

[0111] For the embodiment in which the inlet of the pressure regulating structure 3 is connected with the outlet of the second heat exchanger 12 (i.e. the pressure regulating structure 3 is arranged downstream of the second heat exchanger 12), the refrigerant pressure at the inlet of the pressure regulating structure 3 is equal to or substantially equal to the refrigerant pressure in the second heat exchanger 12, and since the second heat exchanger 12 is in parallel with the vehicle refrigerator 22, the outlet of the pressure regulating structure 3 is in communication with the outlet of the vehicle refrigerator 22, and the refrigerant pressure at the outlet of the pressure regulating structure 3 is equal to or substantially equal to the refrigerant pressure at the outlet of the vehicle refrigerator 22.

[0112] The refrigerant pressure in the second heat exchanger 12 (i.e. the evaporation pressure of the refrigerant) is positively correlated with the evaporation temperature of the refrigerant, i.e. the smaller the refrigerant pressure, the lower the evaporation temperature of the refrigerant. By adjusting the refrigerant pressures at the inlet and outlet of the pressure regulating structure 3, the refrigerant pressures in the second heat exchanger 12 and the vehicle refrigerator 22 can be adjusted so that the refrigerant pressures in the second heat exchanger 12 and the vehicle refrigerator 22 are different, thereby making the evaporation temperatures of the refrigerants in the second heat exchanger 12 and the vehicle refrigerator 22 different, so that the second heat exchanger 12 and the vehicle refrigerator 22 can have different cooling speeds to meet the different temperature requirements of the user for the temperature of the passenger compartment and the temperature in the vehicle refrigerator 22, for the differentiated requirements of the target temperature when the vehicle refrigerator 22 and the air conditioning system 1 are used simultaneously.

[0113] Optionally, for the embodiment that the inlet of the pressure regulating structure 3 is connected with the outlet of the second heat exchanger 12, in the first conduction state, the refrigerant pressure at the inlet side of the pressure regulating structure 3 can be greater than the refrigerant pressure at the outlet side of the pressure regulating structure 3, so that the refrigerant pressure in the second heat exchanger 12 is greater than the refrigerant pressure in the car refrigerator 22. Since in the first conduction state, the refrigerant pressure in the second heat exchanger 12 is greater than the refrigerant pressure in the car refrigerator 22, the evaporation temperature of the refrigerant in the second heat exchanger 12 is greater than the evaporation temperature of the refrigerant in the car refrigerator 22, that is, in the case that the air conditioning system 1 is normally working, the refrigeration temperature of the car refrigerator 22 is lower than the refrigeration temperature of the air conditioning system 1, so as to meet the demand of the lower refrigeration temperature of the car refrigerator 22 in the case that the second heat exchanger 12 and the car refrigerator 22 share the compressor 14 and refrigerate at the same time, and improve the refrigeration capacity and the refrigeration speed of the car refrigerator 22.

[0114] For the above-mentioned embodiment, the pressure regulating structure 3 can be a throttle valve, and in the first conduction state, the refrigerant pressure at the inlet side of the throttle valve can be greater than the refrigerant pressure at the outlet side of the throttle valve. The throttle valve can adjust the amount of refrigerant passing through the throttle valve by adjusting the opening degree of the throttle valve, so that the refrigerant pressures at the inlet side and the outlet side of the throttle valve are different. In other embodiments, the pressure regulating structure 3 can also be a pressure regulating valve, a flow regulating valve, etc.

[0115] Optionally, for the embodiment that the inlet of the pressure regulating structure 3 is connected with the outlet of the car refrigerator 22, in the first conduction state, the refrigerant pressure at the inlet side of the pressure regulating structure 3 can be less than the refrigerant pressure at the outlet side of the pressure regulating structure 3, so that the refrigerant pressure in the second heat exchanger 12 is greater than the refrigerant pressure in the car refrigerator 22, and the evaporation temperature of the refrigerant in the second heat exchanger 12 is greater than the evaporation temperature of the refrigerant in the car refrigerator 22, that is, in the case that the air conditioning system 1 is normally working, the refrigeration temperature of the car refrigerator 22 is lower than the refrigeration temperature of the air conditioning system 1, so as to meet the demand of the lower refrigeration temperature of the car refrigerator 22 in the case that the second heat exchanger 12 and the car refrigerator 22 share the compressor 14 and refrigerate at the same time, and improve the refrigeration capacity and the refrigeration speed of the car refrigerator 22.

[0116] For the above-mentioned embodiment, the pressure regulating structure 3 can be a pressure increasing valve, and in the first conduction state, the refrigerant pressure at the inlet side of the pressure increasing valve can be less than the refrigerant pressure at the outlet side of the pressure increasing valve.

[0117] Optionally, the pressure regulating structure 3 also has a second conduction state, in which the refrigerant pressure at the inlet side of the pressure regulating structure 3 is the same as the refrigerant pressure at the outlet side of the pressure regulating structure 3. In the second conduction state, the refrigerant pressures at the inlet side and the outlet side of the pressure regulating structure 3 are the same, and the pressure regulating structure 3 can be regarded as a through-flow pipeline. At this time, the refrigerant pressures in the second heat exchanger 12 and the vehicle-mounted refrigerator 22 connected in parallel are the same, and the evaporation temperatures of the refrigerants are also the same.

[0118] When the vehicle-mounted refrigerator 22 has a high demand and the air conditioner has a low demand, the pressure regulating structure 3 can be in the first conduction state to preferentially meet the refrigeration demand of the vehicle-mounted refrigerator 22. When the vehicle-mounted refrigerator 22 has a low demand and the air conditioner has a high demand, the pressure regulating structure 3 can be in the second conduction state to preferentially meet the refrigeration demand of the air conditioner system 1.

[0119] Optionally, in the first conduction state, the absolute value of the difference between the refrigerant pressure at the inlet side of the pressure regulating structure 3 and the refrigerant pressure at the outlet side of the pressure regulating structure 3 is 150 kPa-200 kPa. When the difference between the refrigerant pressures is within this range, the refrigeration temperature of the vehicle-mounted refrigerator 22 can be as low as possible while ensuring the normal operation of the air conditioner system 1, thereby meeting the refrigeration needs of the vehicle-mounted refrigerator 22.

[0120] In order to improve the intelligent degree of the vehicle thermal management system 100, optionally, as shown in FIG. 1, the air conditioner system 1 further includes a first temperature and pressure sensor 13 located downstream of the second heat exchanger 12, and the vehicle thermal management system 100 further includes a second temperature and pressure sensor 25 located downstream of the vehicle-mounted refrigerator 22. The vehicle thermal management system 100 further includes a controller, and the first temperature and pressure sensor 13, the second temperature and pressure sensor 25, and the pressure regulating structure 3 are all electrically connected to the controller.

[0121] The first temperature and pressure sensor 13 can detect the refrigerant pressure and the temperature of the refrigerant in the second heat exchanger 12, and the second temperature and pressure sensor 25 can detect the refrigerant pressure and the temperature of the refrigerant in the vehicle-mounted refrigerator 22, and transmit the measured pressure and temperature information to the controller. The controller can adjust the difference between the refrigerant pressure at the inlet side of the pressure regulating structure 3 and the refrigerant pressure at the outlet side of the pressure regulating structure 3 according to the obtained pressure and temperature data, so that the air conditioner system 1 and the vehicle-mounted refrigerator 22 can both operate at the refrigeration temperature required by the user.

[0122] In another embodiment provided by the present disclosure, one of the at least two vehicle refrigerators 22 is heated by the refrigerant flowing through the vehicle refrigerator 22, and the other of the at least two vehicle refrigerators 22 is cooled by the cooling member, thereby realizing the first working mode described above. Specifically, as shown in FIG. 4, the vehicle thermal management system 100 comprises the compressor 14, the at least two vehicle refrigerators 22 are connected in parallel with each other, the outlet of the compressor 14 is connected to the refrigerant inlets of the at least two vehicle refrigerators 22, and the outlet of the compressor 14 can be selectively connected to or cut off from the refrigerant inlets of each of the at least two vehicle refrigerators 22, and the refrigerant outlets of the at least two vehicle refrigerators 22 are connected to the inlet of the compressor 14. The at least two vehicle refrigerators 22 have cooling members for cooling the article storage spaces. In the first working mode, the refrigerant can flow through one of the at least two vehicle refrigerators 22 and heat the article storage space of the vehicle refrigerator 22, and the cooling member on the other of the at least two vehicle refrigerators 22 can cool the article storage space of the vehicle refrigerator 22.

[0123] Since the outlet of the compressor 14 can be selectively connected to or cut off from the refrigerant inlets of the at least two vehicle refrigerators 22, the refrigerant flowing out of the compressor 14 can be selectively introduced into any one of the at least two vehicle refrigerators 22 to exchange heat with the article storage space of the vehicle refrigerator 22, and therefore, in the first working mode described above, the compressor 14 can be connected to one of the at least two vehicle refrigerators 22 and cut off from the other of the at least two vehicle refrigerators 22, so that one of the at least two vehicle refrigerators 22 is heated by the refrigerant and the other of the at least two vehicle refrigerators 22 is cooled by the cooling member. Here, the outlet of the compressor 14 being selectively connected to or cut off from the refrigerant inlets of the at least two vehicle refrigerators 22 can be realized by a switching valve or a switch valve, and the present disclosure does not limit the same.

[0124] In addition, the refrigerant inlets of the at least two vehicle refrigerators 22 are connected to the outlet of the same compressor 14, and the refrigerant outlets of the at least two vehicle refrigerators 22 are connected to the inlet of the same compressor 14, so that the vehicle storage space can be increased and the user's demand for different storage temperatures for different foods can be met as much as possible without increasing the cost and the volume of the vehicle too much. Alternatively, the compressor 14 described above can be the compressor 14 of the air conditioning system 1, so that the plurality of vehicle refrigerators 22 can share the compressor 14 with the air conditioning system 1.

[0125] Optionally, each of the vehicle refrigerators 22 comprises a refrigerator heat exchanger 223 for exchanging heat with the article storage space of the vehicle refrigerator 22, the refrigerator heat exchangers 223 of the at least two vehicle refrigerators 22 are connected in parallel with each other, the outlet of the compressor 14 is connected to the inlet of the refrigerator heat exchangers 223 of the at least two vehicle refrigerators 22, and the outlet of the refrigerator heat exchangers 223 of the at least two vehicle refrigerators 22 is connected to the inlet of the compressor 14.

[0126] Optionally, each of the vehicle refrigerators 22 can also have a heating element 225 for heating the article storage space. On the one hand, the article storage space can also be cooled by the heating element 225 instead of the refrigerant, providing multiple options for means of heating the article storage space, and on the other hand, when the vehicle refrigerator 22 heats the article storage space by the refrigerant flowing therethrough, the heating element 225 can also be turned on to improve the heating efficiency of the article storage space.

[0127] Optionally, the vehicle thermal management system 100 can also comprise a fifth working mode, in which the refrigerant can flow through at least two of the vehicle refrigerators 22 connected in parallel and heat the article storage spaces of the at least two vehicle refrigerators 22. When the user has a heating demand for at least two of the plurality of vehicle refrigerators 22, the vehicle thermal management system 100 can be placed in the fifth working mode, and the outlet of the compressor 14 can be connected to the at least two vehicle refrigerators 22, so as to heat the at least two vehicle refrigerators 22 by the refrigerant.

[0128] In the above-mentioned fifth working mode, the refrigerant can flow through at least two of the vehicle refrigerators 22 connected in parallel and heat the article storage spaces of the at least two vehicle refrigerators 22 to different temperatures to meet the user's demand for different article heating temperatures of different vehicle refrigerators 22. For example, the refrigerant in one of the at least two vehicle refrigerators 22 can heat the article storage space of the vehicle refrigerator 22 to a temperature holding temperature, so that the user can use the vehicle refrigerator 22 to hold articles, and the refrigerant in another of the at least two vehicle refrigerators 22 can heat the article storage space of the vehicle refrigerator 22 to a heating temperature, so that the user can use the vehicle refrigerator 22 to heat articles.

[0129] Optionally, the vehicle thermal management system 100 further has a sixth working mode, in which the cooling elements on at least two of the plurality of vehicle refrigerators 22 can cool the article storage spaces of the at least two vehicle refrigerators 22. When the user has cooling requirements for at least two of the plurality of vehicle refrigerators 22, the vehicle thermal management system 100 can be in the sixth working mode, in which the outlet of the compressor 14 is not connected to the at least two vehicle refrigerators 22, and the at least two vehicle refrigerators 22 cool the article storage spaces by the cooling elements.

[0130] In the above-mentioned sixth working mode, the cooling elements on at least two of the plurality of vehicle refrigerators 22 cool the article storage spaces of the at least two vehicle refrigerators 22 to different temperatures to meet the user's different article cooling temperature requirements for different vehicle refrigerators 22. For example, the cooling element on one of the plurality of vehicle refrigerators 22 can cool the article storage space of the vehicle refrigerator 22 to a refrigeration temperature to enable the user to refrigerate articles using the vehicle refrigerator 22, and the cooling element on another of the plurality of vehicle refrigerators 22 can cool the article storage space of the vehicle refrigerator 22 to a freezing temperature to enable the user to freeze articles using the vehicle refrigerator 22.

[0131] Optionally, as shown in FIG. 4, the vehicle thermal management system 100 further includes a first heat exchanger 15 and at least two refrigerator expansion valves 26, which correspond to the at least two vehicle refrigerators 22 one-to-one; the outlet of the compressor 14 is connected to the refrigerant inlets of the at least two vehicle refrigerators 22, the refrigerant outlets of the at least two vehicle refrigerators 22 are respectively connected to the inlets of the corresponding refrigerator expansion valves 26, the outlets of the at least two refrigerator expansion valves 26 are connected to the inlet of the first heat exchanger 15, and the outlet of the first heat exchanger 15 is connected to the inlet of the compressor 14. The compressor 14, the vehicle refrigerator 22, the refrigerator expansion valve 26, and the first heat exchanger 15 can be connected in series to form a refrigerant circuit, the high-temperature and high-pressure gaseous refrigerant discharged from the compressor 14 flows into the vehicle refrigerator 22 and releases heat in the vehicle refrigerator 22 to heat the article storage space, and the refrigerant after heat release is throttled and depressurized by the refrigerator expansion valve 26 to become low-temperature and low-pressure liquid refrigerant, which enters the first heat exchanger 15 and finally returns to the compressor 14 after heat absorption.

[0132] Optionally, the above-mentioned first heat exchanger 15 can be a heat exchanger of the air conditioning system 1, for example, an outdoor heat exchanger of the air conditioning system 1. The above-mentioned first heat exchanger 15 can also be a heat exchanger in a battery thermal management system for cooling a battery pack; the above-mentioned first heat exchanger 15 can also be arranged in an electric drive system, so that the refrigerant can provide cold energy to the cooling liquid in the electric drive system through the second heat exchanger 12 to cool the battery pack, the motor, the motor controller, and other equipment with cooling requirements.

[0133] It can be understood that, for the embodiment in which the vehicle refrigerator 22 comprises the refrigerator heat exchanger 223, the outlet of the compressor 14 is connected with the inlet of the refrigerator heat exchanger 223, the outlet of the refrigerator heat exchanger 223 is connected with the inlet of the refrigerator expansion valve 26, the outlet of the refrigerator expansion valve 26 is connected with the inlet of the first heat exchanger 15, and the outlet of the first heat exchanger 15 is connected with the inlet of the compressor 14. Thus, the refrigerant in the refrigerator heat exchanger 223 can be used to heat the article storage space of the vehicle refrigerator 22, so as to realize the heating function of the vehicle refrigerator 22.

[0134] Optionally, the refrigerator expansion valve 26 mentioned in the above various embodiments can be integrated on the vehicle refrigerator 22, can be installed outside the vehicle refrigerator 22 and connected with the heat exchange structure (for example, the refrigerator heat exchanger 223) in the vehicle refrigerator 22 through a pipeline, or can be installed inside the vehicle refrigerator 22, for example, at the inlet or outlet of the heat exchange structure in the vehicle refrigerator 22, and the specific installation position of the refrigerator expansion valve 26 is not limited in the disclosure.

[0135] In addition, the vehicle thermal management system 100 in the above various embodiments can comprise the air conditioning system 1, and the air conditioning system 1 comprises the above-mentioned compressor 14, that is, the air conditioning system 1 shares the compressor 14 with the at least two vehicle refrigerators 22. The compressor 14 not only plays a role of compressing and driving the refrigerant in the refrigerant flow path where the devices (for example, the air conditioning evaporator, the air conditioning condenser, etc.) of the air conditioning system 1 are located, but also plays a role of compressing and driving the refrigerant in the refrigerant flow path where the at least two vehicle refrigerators 22 are located, so as to achieve the effect of providing refrigerant for different thermal management devices by using the same compressor 14.

[0136] By using the compressor 14 in the air conditioning system 1 to provide the flowing refrigerant for the at least two vehicle refrigerators 22, the utilization rate of the compressor 14 can be improved, the integration degree of the vehicle thermal management system 100 can be improved, the number of devices required by the at least two vehicle refrigerators 22 can be reduced, and the cost significantly increased due to the arrangement of the at least two vehicle refrigerators 22 can be avoided.

[0137] In addition, in order to improve the heat exchange effect between the refrigerator heat exchanger 223 and the air in the article storage space, optionally, as shown in FIG. 3, the refrigerator heat exchanger 223 comprises a heat exchange pipe 221 and a heat exchange shell 222, the inner surface of the heat exchange shell 222 defines the article storage space, the outlet of the compressor 14 is connected with the inlet of the heat exchange pipe 221, the outlet of the heat exchange pipe 221 is connected with the inlet of the compressor 14, and the heat exchange pipe 221 is in heat conduction contact with the outer surface of the heat exchange shell 222, so that the refrigerant in the heat exchange pipe 221 can directly exchange heat with the air in the article storage space through the heat exchange shell 222.

[0138] The inlet and outlet of the compressor 14 are connected with the outlet and inlet of the heat exchange pipe 221, and the heat exchange pipe 221 can be provided with the refrigerant for heat exchange. The heat exchange pipe 221 is in heat conduction contact with the outer surface of the heat exchange shell 222, and the inner surface of the heat exchange shell 222 defines an article containing space. The heat exchange shell 222 can be directly in contact with the air in the article containing space, so that the cold or heat of the refrigerant in the heat exchange pipe 221 can be directly conducted to the heat exchange shell 222 through the heat exchange pipe 221, and heat exchange with the air in the article containing space through the heat exchange shell 222, reducing the loss of cold or heat in the conduction process, and improving the refrigeration or heating efficiency of the vehicle-mounted refrigerator 22.

[0139] Optionally, the heat conduction coefficient of the heat exchange shell 222 can be 201 W / mk-237 W / mk. The material with this coefficient has good heat conduction performance and can meet the heat exchange demand of the heat exchange pipe 221 for heat exchange with the air in the article containing space through the heat exchange shell 222.

[0140] The specific material of the heat exchange shell 222 is not limited in the present disclosure, for example, the material of the heat exchange shell 222 can be aluminum or copper.

[0141] As mentioned above, the vehicle-mounted refrigerator 22 can include a heating element 225, as shown in FIG. 8, in an embodiment provided by the present disclosure, the heating element 225 can include a heating film, and the heating film is covered on the outer surface of the heat exchange shell 222 and / or the side of the heat exchange pipe 221 away from the heat exchange shell 222.

[0142] For the above-mentioned embodiment of the vehicle-mounted refrigerator 22 including a cooling element, the cooling element can include a semiconductor refrigeration sheet, and the semiconductor refrigeration sheet is covered on the outer surface of the heat exchange shell 222 and / or the side of the heat exchange pipe 221 away from the heat exchange shell 222.

[0143] The heating film or semiconductor refrigeration sheet covered on the outer surface of the heat exchange shell 222 can directly exchange heat with the heat exchange shell 222, and exchange heat with the air in the article containing space through the heat exchange shell 222, reducing the heat loss in the heating or refrigeration process.

[0144] The heating film or semiconductor refrigeration sheet covered on the side of the heat exchange pipe 221 away from the heat exchange shell 222 can not only exchange heat with the air in the article containing space through the heat exchange pipe 221 and the heat exchange shell 222, but also can press the heat exchange pipe 221 tightly on the heat exchange shell 222, to ensure the heat conduction contact between the heat exchange pipe 221 and the heat exchange shell 222.

[0145] To further improve the heat exchange efficiency, the vehicle refrigerator 22 can optionally comprise a fan 224 as shown in FIG. 1, which is configured to accelerate the air flow in the article storage space. For example, the fan 224 is configured to generate air flow that can exchange heat with the refrigerant in the heat exchange pipe 221 and enter the article storage space. The fan 224 can accelerate the flow between the air near the heat exchange pipe 221 and the air in the article storage space, thereby improving the heat exchange efficiency between the heat exchange pipe 221 and the air in the article storage space, and improving the heating or cooling speed of the vehicle refrigerator 22. It can be understood that when the heating element 225 is heated or the cooling element is cooled, the fan 224 can accelerate the flow between the air near the heating element 225 or the cooling element and the air in the article storage space, thereby improving the heat exchange efficiency between the heating element 225 or the cooling element and the air in the article storage space, and improving the heating or cooling speed of the vehicle refrigerator 22.

[0146] Optionally, the heat exchange shell 222 is provided with an air inlet, and the fan 224 is arranged at the air inlet. The air inlet is arranged on the heat exchange shell 222 to accommodate the fan 224, so that the fan 224 does not occupy the volume of the article storage space. At the same time, the air inlet also enables the fan 224 to directly drive the air on both sides of the air inlet to flow relative to each other, forming a convection, thereby improving the heat exchange efficiency of the heat exchange pipe 221.

[0147] According to a third aspect of the present disclosure, as shown in FIGS. 1-8, the present disclosure provides a vehicle thermal management system 100, comprising a first compressor 14, an air conditioner refrigerant flow path 5, and a plurality of refrigerator heat exchange flow paths 4, and a vehicle refrigerator 22 is arranged on the refrigerator heat exchange flow path 4. The air conditioner refrigerant flow path 5 is connected to the first compressor 14, and at least one of the plurality of refrigerator heat exchange flow paths 4 is connected to the first compressor 14.

[0148] Here, the above-mentioned refrigerator heat exchange flow path 4 on which the vehicle refrigerator 22 is arranged means that the heat exchange pipeline or heat exchange component through which the heat exchange medium (e.g., refrigerant) of the vehicle refrigerator 22 flows is connected to the refrigerator heat exchange flow path 4, so that the heat exchange medium can flow from the refrigerator heat exchange flow path 4 into the heat exchange pipeline or heat exchange component of the vehicle refrigerator 22, and after exchanging heat with the article storage space in the vehicle refrigerator 22, it flows out of the vehicle refrigerator 22.

[0149] Through the above technical solution, since the plurality of vehicle refrigerators 22 each have an independent article storage space, the storage space in the vehicle can be increased, and more articles that require storage at a certain temperature can be stored. In addition, the plurality of vehicle refrigerators 22 can be installed at different positions in the passenger compartment of the vehicle, so that users at different positions in the passenger compartment can easily take the articles in the vehicle refrigerators 22. Since each vehicle refrigerator 22 has a corresponding refrigerator heat exchange flow path 4, each article storage space can have a different storage temperature to meet the needs of users for different storage temperatures of different foods.

[0150] In addition, the air conditioner refrigerant flow path 5 and the plurality of refrigerator heat exchange flow paths 4 are connected with the same first compressor 14, so that the vehicle storage space can be increased and the different storage temperature requirements of different foods can be met without increasing the vehicle cost and the vehicle volume too much.

[0151] It can be understood that, in order to enable the refrigerant to flow into the vehicle refrigerator 22 and exchange heat with the article containing space in the vehicle refrigerator 22, the vehicle refrigerator 22 has a channel for the refrigerant to flow through. For example, the vehicle refrigerator 22 can be provided with a refrigerant heat exchange flow channel, or the vehicle refrigerator 22 can be provided with a refrigerant heat exchange chamber, or the vehicle refrigerator 22 can be provided with a refrigerant heat exchange pipeline, or the vehicle refrigerator 22 can be provided with a heat exchanger (for example, the refrigerator heat exchanger 223 mentioned below). The present disclosure does not limit how the refrigerant specifically exchanges heat with the article containing space in the vehicle refrigerator 22, as long as the refrigerant can flow into the vehicle refrigerator 22 and exchange heat with the article containing space in the vehicle refrigerator 22.

[0152] In addition, it should be noted that the refrigerant flowing from the refrigerator heat exchange flow path 4 into the vehicle refrigerator 22 can release heat or absorb heat, that is, the article containing space in the vehicle refrigerator 22 can be heated or cooled, and the present disclosure does not limit this. In addition, for the plurality of refrigerator heat exchange flow paths 4, the refrigerant flowing into the corresponding vehicle refrigerator 22 can release heat or absorb heat, that is, the plurality of vehicle refrigerators 22 can be in heating mode or cooling mode; or a part of the plurality of refrigerator heat exchange flow paths 4 can release heat after flowing into the corresponding vehicle refrigerator 22, and the other part of the plurality of refrigerator heat exchange flow paths 4 can absorb heat after flowing into the corresponding vehicle refrigerator 22, that is, a part of the plurality of vehicle refrigerators 22 is in heating mode and the other part of the plurality of vehicle refrigerators 22 is in cooling mode, and the present disclosure does not limit this.

[0153] In other words, for the embodiment in which the vehicle refrigerator 22 has the refrigerator heat exchanger 223, the refrigerator heat exchanger 223 can be used as an evaporator to cool the air in the article containing space, so as to achieve the requirement of refrigerating or freezing the articles in the article containing space. The refrigerator heat exchanger 223 can also be used as a condenser to heat the air in the article containing space, so as to heat and keep warm the articles in the article containing space. The present disclosure does not limit whether the refrigerator heat exchanger 223 is used as an evaporator or a condenser, or whether the refrigerator heat exchanger 223 can be used as an evaporator when there is a refrigeration requirement and can be used as a condenser when there is a heating requirement.

[0154] In addition, the at least one of the plurality of refrigerator heat exchange flow paths 4 connected to the first compressor 14 can be only one of the plurality of refrigerator heat exchange flow paths 4 connected to the first compressor 14, or a part (more than or equal to two) of the plurality of refrigerator heat exchange flow paths 4 connected to the first compressor 14, or all of the plurality of refrigerator heat exchange flow paths 4 connected to the first compressor 14, which are not limited in the present disclosure. For the case that a part of the plurality of refrigerator heat exchange flow paths 4 is not connected to the first compressor 14, the refrigerator heat exchange flow path 4 not connected to the first compressor 14 can be connected to the second compressor.

[0155] In addition, the plurality of refrigerator heat exchange flow paths 4 can be connected in series or in parallel, or a part of the refrigerator heat exchange flow paths 4 are connected in parallel and the other part of the refrigerator heat exchange flow paths 4 are connected in series, as long as at least one of the refrigerator heat exchange flow paths 4 and the air conditioner refrigerant flow path 5 are connected to the same first compressor 14, and the specific series-parallel connection relationship between the plurality of refrigerator heat exchange flow paths 4 is not limited in the present disclosure.

[0156] As shown in FIGS. 5 and 6, in an embodiment provided by the present disclosure, the plurality of refrigerator heat exchange flow paths 4 are connected in series, that is, the plurality of vehicle-mounted refrigerators 22 are connected in series. The plurality of vehicle-mounted refrigerators 22 connected in series can all heat or all cool, or one vehicle-mounted refrigerator 22 heats and the other vehicle-mounted refrigerator 22 cools.

[0157] For example, as shown in FIGS. 5 and 6, the plurality of refrigerator heat exchange flow paths 4 include a first refrigerator heat exchange branch 41 and a second refrigerator heat exchange branch 42, and the plurality of vehicle-mounted refrigerators 22 include a first vehicle-mounted refrigerator 226 arranged on the first refrigerator heat exchange branch 41 and a second vehicle-mounted refrigerator 227 arranged on the second refrigerator heat exchange branch 42. The outlet of the first compressor 14 is connected to the inlet of the first refrigerator heat exchange branch 41, the outlet of the first refrigerator heat exchange branch 41 is connected to the inlet of the second refrigerator heat exchange branch 42, and the outlet of the second refrigerator heat exchange branch 42 is connected to the inlet of the first compressor 14. That is, at least two of the plurality of refrigerator heat exchange flow paths 4 are connected in series and connected to the first compressor 14.

[0158] In the above embodiment, the refrigerant in the first refrigerator heat exchange branch 41 can be used to release heat to the first vehicle-mounted refrigerator 226, and the refrigerant in the second refrigerator heat exchange branch 42 can be used to absorb heat from the second vehicle-mounted refrigerator 227; or the refrigerant in the first refrigerator heat exchange branch 41 is used to release heat to the first vehicle-mounted refrigerator 226, and the refrigerant in the second refrigerator heat exchange branch 42 is used to release heat to the second vehicle-mounted refrigerator 227; or the refrigerant in the first refrigerator heat exchange branch 41 is used to absorb heat from the first vehicle-mounted refrigerator 226, and the refrigerant in the second refrigerator heat exchange branch 42 is used to absorb heat from the second vehicle-mounted refrigerator 227, which are not limited in the present disclosure.

[0159] In a first implementation provided by the present disclosure, the refrigerant in the first refrigerator heat exchange branch 41 is used to release heat to the first vehicle refrigerator 226, and the refrigerant in the second refrigerator heat exchange branch 42 is used to absorb heat of the second vehicle refrigerator 227. Specifically, as shown in FIG. 5, the vehicle thermal management system 100 further comprises a refrigerator expansion valve 26, and the outlet of the first refrigerator heat exchange branch 41 is connected to the inlet of the second refrigerator heat exchange branch 42 via the refrigerator expansion valve 26.

[0160] In the above-mentioned first implementation, the high-temperature and high-pressure gaseous refrigerant discharged by the first compressor 14 flows into the first vehicle refrigerator 226 and releases heat to the article storage space of the first vehicle refrigerator 226 to raise the temperature of the article storage space of the first vehicle refrigerator 226, thereby achieving heating or temperature preservation of the articles. The refrigerant after releasing heat in the first vehicle refrigerator 226 is throttled and depressurized by the refrigerator expansion valve 26 to become low-temperature and low-pressure liquid refrigerant, which enters the second vehicle refrigerator 227 and absorbs heat of the article storage space of the second vehicle refrigerator 227 to lower the temperature of the article storage space of the second vehicle refrigerator 227, thereby achieving refrigeration or freezing of the articles.

[0161] Optionally, the first vehicle refrigerator 226 can have a cooling member for cooling air in the article storage space of the first vehicle refrigerator 226; and / or the second vehicle refrigerator 227 can have a heating member 225 for heating air in the article storage space of the second vehicle refrigerator 227. Since the specific positions of the first vehicle refrigerator 226 and the second vehicle refrigerator 227 on the vehicle can be different, if the user needs the first vehicle refrigerator 226 to refrigerate or freeze the articles, the article storage space can be cooled by the cooling member, at this time, the refrigerant does not flow through the first vehicle refrigerator 226 (for example, the first compressor 14 is not started, or the first vehicle refrigerator 226 is short-circuited by a short-circuit flow path so that the refrigerant does not flow through the first vehicle refrigerator 226); if the user needs the second vehicle refrigerator 227 to heat or preserve the temperature of the articles, the article storage space can be heated by the heating member 225, at this time, the refrigerant does not flow through the second vehicle refrigerator 227 (for example, the first compressor 14 is not started, or the second vehicle refrigerator 227 is short-circuited by a short-circuit flow path so that the refrigerant does not flow through the second vehicle refrigerator 227). By providing the cooling member on the first vehicle refrigerator 226 and / or the heating member 225 on the second vehicle refrigerator 227, the functions of the first vehicle refrigerator 226 and the second vehicle refrigerator 227 can be more diverse, the user needs can be met, and the user experience can be improved.

[0162] Optionally, the vehicle thermal management system 100 can further comprise an air conditioning system 1, the air conditioning system 1 comprising the air conditioning refrigerant flow path 5 and the first compressor 14. That is, the refrigerator heat exchange flow path 4 shares the first compressor 14 of the air conditioning system 1 with the air conditioning refrigerant flow path 5, the first compressor 14 connected to the vehicle refrigerator 22 is the first compressor 14 of the air conditioning system 1, the first compressor 14 not only plays a role of compressing and driving refrigerant in the refrigerant flow path where the devices (such as air conditioning evaporator, air conditioning condenser, etc.) of the air conditioning system 1 are located, but also plays a role of compressing and driving refrigerant in the heat exchange flow path where the vehicle refrigerator 22 is located, so as to achieve the effect of using the same first compressor 14 to provide refrigerant for different thermal management devices.

[0163] By using the first compressor 14 of the air conditioning system 1 to provide flowing refrigerant for the refrigerator heat exchanger 223 of at least one vehicle refrigerator 22, the utilization rate of the first compressor 14 can be improved, the integration of the vehicle thermal management system 100 can be improved, the number of devices required by multiple vehicle refrigerators 22 can be reduced, and the cost increase caused by the setting of multiple vehicle refrigerators 22 can be avoided.

[0164] Optionally, the outlet of the first compressor 14 can be selectively communicated or blocked with the inlet of the first refrigerator heat exchange branch 41 and the inlet of the air conditioning refrigerant flow path 5. In this way, the first compressor 14 and the air conditioning refrigerant flow path 5 can be connected in series to form a refrigerant circuit, the first compressor 14 and the first refrigerator heat exchange branch 41 and the second refrigerator heat exchange branch 42 can also be connected in series to form a circuit, and the high-temperature and high-pressure gaseous refrigerant discharged from the first compressor 14 can flow into the air conditioning refrigerant flow path 5 to realize the functions of heating or cooling the passenger compartment, or can flow into the first refrigerator heat exchange branch 41 and the second refrigerator heat exchange branch 42 to realize the functions of heating the first vehicle refrigerator 226 and cooling the second vehicle refrigerator 227. The selective communication or blocking of the outlet of the first compressor 14 with the inlet of the first refrigerator heat exchange branch 41 and the inlet of the air conditioning refrigerant flow path 5 can be realized by a three-way valve, or can be realized by setting two switch valves, and the present disclosure does not limit this.

[0165] Optionally, as shown in FIG. 5, the air conditioning system 1 can further comprise a first heat exchanger 15, a second heat exchanger 12, and an air conditioning expansion valve 16, all of which are arranged on the air conditioning refrigerant flow path 5, and the first heat exchanger 15 is located upstream of the air conditioning expansion valve 16 (i.e., the outlet of the first heat exchanger 15 is connected to the inlet of the air conditioning expansion valve 16), and the second heat exchanger 12 is located downstream of the air conditioning expansion valve 16 (i.e., the outlet of the air conditioning expansion valve 16 is connected to the inlet of the second heat exchanger 12). The outlet of the first compressor 14 is also connected to the inlet of the air conditioning refrigerant flow path 5, and the outlet of the first compressor 14 can be selectively connected or cut off with the inlet of the first refrigerator heat exchange branch 41 and the inlet of the air conditioning refrigerant flow path 5, and the outlet of the air conditioning refrigerant flow path 5 is connected to the inlet of the first compressor 14.

[0166] For the embodiment in which the air conditioning system 1 is used to realize the heating function of the passenger compartment, the high-temperature and high-pressure gaseous refrigerant flowing out of the outlet of the first compressor 14 enters the first heat exchanger 15 and releases heat to the passenger compartment, realizing the heating of the passenger compartment, at this time the first heat exchanger 15 can be used as an indoor condenser, and the refrigerant after heat release flows into the second heat exchanger 12 through the air conditioning expansion valve 16 for throttling and pressure reduction and absorbs heat at the second heat exchanger 12, and the refrigerant after heat absorption finally returns to the first compressor 14. Here, the refrigerant can absorb the heat of the outside atmosphere at the second heat exchanger 12, i.e., the second heat exchanger 12 can be an outdoor heat exchanger; alternatively, the second heat exchanger 12 can also be arranged in the electric heating management system, so that the refrigerant can absorb the heat emitted by the battery pack or the motor at the second heat exchanger 12, realizing the cooling of the battery pack or the motor.

[0167] For the embodiment in which the air conditioning system 1 is used to realize the heating function of the passenger compartment, the high-temperature and high-pressure gaseous refrigerant flowing out of the outlet of the first compressor 14 enters the first heat exchanger 15 and releases heat to the passenger compartment, realizing the heating of the passenger compartment, at this time the first heat exchanger 15 can be used as an indoor condenser, and the refrigerant after heat release flows into the second heat exchanger 12 through the air conditioning expansion valve 16 for throttling and pressure reduction and absorbs heat at the second heat exchanger 12, and the refrigerant after heat absorption finally returns to the first compressor 14. Here, the refrigerant can absorb the heat of the outside atmosphere at the second heat exchanger 12, i.e., the second heat exchanger 12 can be an outdoor heat exchanger; alternatively, the second heat exchanger 12 can also be arranged in the electric heating management system, so that the refrigerant can absorb the heat emitted by the battery pack or the motor at the second heat exchanger 12, realizing the cooling of the battery pack or the motor.

[0168] As shown in FIG. 6, in the second embodiment provided in the present disclosure, the at least two refrigerator heat exchange flow paths 4 are also connected in series with each other, but different from the first embodiment described above is that in the second embodiment, the plurality of vehicle-mounted refrigerators 22 connected in series with each other all realize refrigeration.

[0169] Specifically, as shown in FIG. 6, the vehicle thermal management system 100 further comprises a refrigerator expansion valve 26 and a first heat exchanger 15, an outlet of the first compressor 14 is connected with an inlet of the first heat exchanger 15, an outlet of the first heat exchanger 15 is connected with an inlet of the first refrigerator heat exchange branch 41 via the refrigerator expansion valve 26, and an outlet of the first refrigerator heat exchange branch 41 is connected with an inlet of the second refrigerator heat exchange branch 42.

[0170] In the above-mentioned second embodiment, the high-temperature and high-pressure gaseous refrigerant flowing out of the outlet of the first compressor 14 flows into the first heat exchanger 15 and releases heat in the first heat exchanger 15, the refrigerant after heat release is throttled and depressurized by the refrigerator expansion valve 26 to become low-temperature and low-pressure liquid refrigerant, the liquid refrigerant enters the first vehicle refrigerator 226 and absorbs the heat of the article storage space of the first vehicle refrigerator 226 to reduce the temperature of the article storage space of the first vehicle refrigerator 226, the refrigerant after heat absorption at the first vehicle refrigerator 226 still has a certain cooling capacity, and continues to absorb the heat of the article storage space of the second vehicle refrigerator 227 when entering the second vehicle refrigerator 227 to reduce the temperature of the article storage space of the second vehicle refrigerator 227. In the above-mentioned embodiment, the refrigerant sequentially absorbs the temperatures of the article storage space of the first vehicle refrigerator 226 and the article storage space of the second vehicle refrigerator 227, which can realize simultaneous refrigeration of the first vehicle refrigerator 226 and the second vehicle refrigerator 227, and can make the first vehicle refrigerator 226 and the second vehicle refrigerator 227 have different article storage temperatures, for example, the first vehicle refrigerator 226 can realize freezing of articles, and the second vehicle refrigerator 227 can realize refrigeration of articles.

[0171] Here, the outlet of the second refrigerator heat exchange branch 42 can be connected with the inlet of the first compressor 14 to return the refrigerant to the first compressor 14.

[0172] Optionally, the above-mentioned first heat exchanger 15 can be an outdoor heat exchanger, and the refrigerant releases heat to the atmosphere at the first heat exchanger 15.

[0173] Optionally, the first vehicle refrigerator 226 and / or the second vehicle refrigerator 227 has a cooling member for cooling air in the article storage space of the first vehicle refrigerator 226 and / or the second vehicle refrigerator 227; and / or, the first vehicle refrigerator 226 and / or the second vehicle refrigerator 227 has a heating member 225 for heating air in the article storage space of the first vehicle refrigerator 226 and / or the second vehicle refrigerator 227.

[0174] For the case that the first vehicle refrigerator 226 and / or the second vehicle refrigerator 227 has the cooling element, when the first vehicle refrigerator 226 and the second vehicle refrigerator 227 achieve refrigeration by using the refrigerant, the cooling element can improve the cooling efficiency of the first vehicle refrigerator 226 and / or the second vehicle refrigerator 227. In addition, the first vehicle refrigerator 226 and / or the second vehicle refrigerator 227 can also achieve refrigeration by using the cooling element instead of relying on the refrigerant.

[0175] For the case that the first vehicle refrigerator 226 and / or the second vehicle refrigerator 227 has the heating element 225, when the first vehicle refrigerator 226 and / or the second vehicle refrigerator 227 has heated objects or needs to keep objects warm, the heating element 225 can be used to achieve heating of the first vehicle refrigerator 226 and / or the second vehicle refrigerator 227.

[0176] Optionally, as shown in FIG. 6, the vehicle thermal management system 100 can further include an air conditioning system 1, which includes the above-mentioned air conditioning refrigerant flow path 5, the first compressor 14, and the first heat exchanger 15. The air conditioning refrigerant flow path 5 includes a first air conditioning refrigerant branch 51 and a second air conditioning refrigerant branch 52, and the first heat exchanger 15 is arranged on the first air conditioning refrigerant branch 51. The outlet of the first compressor 14 is connected with the inlet of the first air conditioning refrigerant branch 51, the outlet of the first air conditioning refrigerant branch 51 is connected with the inlet of the second air conditioning refrigerant branch 52 and the inlet of the refrigerator expansion valve 26, and the outlet of the first air conditioning refrigerant branch 51 can be selectively connected or cut off with the inlet of the second air conditioning refrigerant branch 52. The selective connection or cut off of the outlet of the first air conditioning refrigerant branch 51 with the inlet of the second air conditioning refrigerant branch 52 can be realized by a switching valve or a switch valve, or can be controlled by an air conditioning expansion valve 16, which is not limited in the present disclosure.

[0177] Because the outlet of the first air conditioning refrigerant branch 51 can be selectively connected or cut off with the inlet of the second air conditioning refrigerant branch 52 and the inlet of the first refrigerator heat exchange branch 41 is selectively connected or cut off by the refrigerator expansion valve 26, the first compressor 14, the first air conditioning refrigerant branch 51, and the second air conditioning refrigerant branch 52 can be connected in series to form a loop, and the first compressor 14, the first air conditioning refrigerant branch 51, the first refrigerator heat exchange branch 41, and the second refrigerator heat exchange branch 42 can also be connected in series to form a loop. In other words, the high-temperature and high-pressure gaseous refrigerant discharged from the first compressor 14 can flow into the first air conditioning refrigerant branch 51 and the second air conditioning refrigerant branch 52 to achieve the functions of passenger compartment heating or passenger compartment refrigeration, or can flow into the first refrigerator heat exchange branch 41 and the second refrigerator heat exchange branch 42 to achieve the refrigeration functions of the first vehicle refrigerator 226 and the second vehicle refrigerator 227.

[0178] Optionally, the air conditioning system 1 further comprises a second heat exchanger 12 and an air conditioning expansion valve 16, both of which are arranged on the second air conditioning refrigerant branch 52, and the second heat exchanger 12 is located downstream of the air conditioning expansion valve 16 (i.e. the outlet of the second heat exchanger 12 is connected to the inlet of the air conditioning expansion valve 16).

[0179] For the embodiment in which the air conditioning system 1 is used to realize the heating function of the passenger compartment, the first heat exchanger 15 can be an indoor condenser, and the second heat exchanger 12 can be an outdoor heat exchanger; for the embodiment in which the air conditioning system 1 is used to realize the cooling function of the passenger compartment, the first heat exchanger 15 can be an outdoor heat exchanger, and the second heat exchanger 12 can be an indoor evaporator.

[0180] Optionally, as shown in FIG. 5, FIG. 6 and FIG. 1, the outlet of the air conditioning refrigerant flow path 5 and the outlet of at least one of the refrigerator heat exchange flow paths 4 are merged. The vehicle thermal management system further comprises a pressure regulating structure 3, which is arranged on the air conditioning refrigerant flow path 5 and close to the outlet of the air conditioning refrigerant flow path 5, and / or the pressure regulating structure 3 is arranged on at least one of the refrigerator heat exchange flow paths 4 and close to the outlet of the refrigerator heat exchange flow path 4, and the pressure regulating structure 3 is used to regulate the refrigerant pressure of the air conditioning refrigerant flow path 5 and the refrigerator heat exchange flow path 4.

[0181] Since the outlet of the air conditioning refrigerant flow path 5 and the outlet of at least one of the refrigerator heat exchange flow paths 4 are merged, i.e. the outlet of the air conditioning refrigerant flow path 5 and the outlet of the refrigerator heat exchange flow path 4 are communicated, and for the embodiment in which the pressure regulating structure 3 is arranged on the air conditioning refrigerant flow path 5 and close to the outlet of the air conditioning refrigerant flow path 5, the refrigerant pressure in the refrigerator heat exchange flow path 4 is equal to or substantially equal to the refrigerant pressure at the outlet of the pressure regulating structure 3, and the refrigerant pressure at the inlet of the pressure regulating structure 3 is equal to or substantially equal to the refrigerant pressure of the flow path upstream of the pressure regulating structure 3 in the air conditioning refrigerant flow path 5; for the embodiment in which the pressure regulating structure 3 is arranged on at least one of the refrigerator heat exchange flow paths 4 and close to the outlet of the refrigerator heat exchange flow path 4, the refrigerant pressure in the flow path upstream of the pressure regulating structure 3 in the refrigerator heat exchange flow path 4 is equal to or substantially equal to the refrigerant pressure at the inlet of the pressure regulating structure 3, and the refrigerant pressure at the outlet of the pressure regulating structure 3 is equal to or substantially equal to the refrigerant pressure of the air conditioning refrigerant flow path 5.

[0182] Therefore, the pressure regulating structure 3 can regulate the refrigerant pressure of the air conditioning refrigerant flow path 5 and the refrigerator heat exchange flow path 4, so as to regulate the refrigerant pressure (i.e. the evaporation pressure of the refrigerant) of the equipment arranged on the air conditioning refrigerant flow path 5 (e.g. the second heat exchanger 12) and the vehicle-mounted refrigerator 22 arranged on the refrigerator heat exchange flow path 4, and further regulate the evaporation temperature and cooling speed of the equipment arranged on the air conditioning refrigerant flow path 5 and the vehicle-mounted refrigerator 22.

[0183] For example, referring to FIG. 1 and FIG. 2, the outlet of the air-conditioning refrigerant flow path 5 and the outlet of the second refrigerator heat exchange branch 42 are connected to the inlet of the first compressor 14, i.e., the outlet of the air-conditioning refrigerant flow path 5 and the outlet of the second refrigerator heat exchange branch 42 are merged. The pressure regulating structure 3 is arranged on the air-conditioning refrigerant flow path 5 and close to the outlet of the air-conditioning refrigerant flow path 5 (for example, downstream of the second heat exchanger 12); or the pressure regulating structure 3 is arranged on the second refrigerator heat exchange branch 42 and downstream of the second vehicle refrigerator 227.

[0184] The pressure regulating structure 3 has a first conduction state, in which the refrigerant pressure on the inlet side of the pressure regulating structure 3 is different from the refrigerant pressure on the outlet side of the pressure regulating structure 3, so that the refrigerant pressure in the second heat exchanger 12 is different from the refrigerant pressure in the second vehicle refrigerator 227.

[0185] For the embodiment in which the pressure regulating structure 3 is arranged on the air-conditioning refrigerant flow path 5 and close to the outlet of the air-conditioning refrigerant flow path 5, the inlet of the pressure regulating structure 3 is connected to the outlet of the second heat exchanger 12, the refrigerant pressure at the inlet of the pressure regulating structure 3 is equal to or substantially equal to the refrigerant pressure in the second heat exchanger 12, and because the second heat exchanger 12 is in parallel with the second vehicle refrigerator 227, the outlet of the pressure regulating structure 3 is in communication with the outlet of the second vehicle refrigerator 227, and the refrigerant pressure at the outlet of the pressure regulating structure 3 is equal to or substantially equal to the refrigerant pressure at the outlet of the second vehicle refrigerator 227.

[0186] Similarly, for the embodiment in which the pressure regulating structure 3 is arranged on the second refrigerator heat exchange branch 42 and downstream of the second vehicle refrigerator 227, i.e., the inlet of the pressure regulating structure 3 is connected to the outlet of the second vehicle refrigerator 227, the refrigerant pressure at the inlet of the pressure regulating structure 3 is equal to or substantially equal to the refrigerant pressure in the second vehicle refrigerator 227, and because the second heat exchanger 12 is in parallel with the second vehicle refrigerator 227, the outlet of the pressure regulating structure 3 is in communication with the outlet of the second heat exchanger 12, and the refrigerant pressure at the outlet of the pressure regulating structure 3 is equal to or substantially equal to the refrigerant pressure at the outlet of the second heat exchanger 12.

[0187] The refrigerant pressure in the second heat exchanger 12 (i.e. the evaporation pressure of the refrigerant) is positively correlated with the evaporation temperature of the refrigerant, i.e. the smaller the refrigerant pressure, the lower the evaporation temperature of the refrigerant. By adjusting the refrigerant pressure at the inlet side and the outlet side of the pressure regulating structure 3, the refrigerant pressure in the second heat exchanger 12 and the refrigerant pressure in the second vehicle refrigerator 227 can be adjusted, so that the refrigerant pressure in the second heat exchanger 12 and the refrigerant pressure in the second vehicle refrigerator 227 are different, thereby making the evaporation temperature of the refrigerant in the second heat exchanger 12 and the second vehicle refrigerator 227 different, so that the second heat exchanger 12 and the second vehicle refrigerator 227 can have different cooling speeds to meet the different temperature requirements of the user for the temperature of the passenger compartment and the temperature in the vehicle refrigerator 22 when the vehicle refrigerator 22 and the air conditioning system 1 are used at the same time.

[0188] Optionally, for the embodiment in which the pressure regulating structure 3 is arranged on the air conditioning refrigerant flow path 5 and close to the outlet of the air conditioning refrigerant flow path 5, and the inlet of the pressure regulating structure 3 is connected to the outlet of the second heat exchanger 12, in the first conduction state, the refrigerant pressure at the inlet side of the pressure regulating structure 3 can be greater than the refrigerant pressure at the outlet side of the pressure regulating structure 3, so that the refrigerant pressure in the second heat exchanger 12 is greater than the refrigerant pressure in the second vehicle refrigerator 227. Since in the first conduction state, the refrigerant pressure in the second heat exchanger 12 is greater than the refrigerant pressure in the second vehicle refrigerator 227, so that the evaporation temperature of the refrigerant in the second heat exchanger 12 is greater than the evaporation temperature of the refrigerant in the second vehicle refrigerator 227, i.e. in the case of normal operation of the air conditioning system 1, the refrigeration temperature of the second vehicle refrigerator 227 is lower than the refrigeration temperature of the air conditioning system 1, thereby meeting the requirement of lower refrigeration temperature of the second vehicle refrigerator 227 in the case of the second heat exchanger 12 and the second vehicle refrigerator 227 sharing the first compressor 14 and the second heat exchanger 12 and the second vehicle refrigerator 227 refrigerating at the same time, and improving the refrigeration capacity and refrigeration speed of the second vehicle refrigerator 227.

[0189] For the above-mentioned embodiment, the pressure regulating structure 3 can be a throttle valve, which can be arranged on the air conditioning refrigerant flow path 5 and located downstream of the second heat exchanger 12. In the first conduction state, the refrigerant pressure at the inlet side of the throttle valve can be greater than the refrigerant pressure at the outlet side of the throttle valve. The throttle valve can adjust the amount of refrigerant passing through the throttle valve by adjusting the opening degree of the throttle valve, so that the refrigerant pressure at the inlet side and the outlet side of the throttle valve is different. In other embodiments, the pressure regulating structure 3 can also be a pressure regulating valve, a flow regulating valve, etc.

[0190] Optionally, for the embodiment that the pressure regulating structure 3 is arranged on the second refrigerator heat exchange branch 42 and located downstream of the second vehicle refrigerator 227, that is, the inlet of the pressure regulating structure 3 is connected with the outlet of the second vehicle refrigerator 227, in the first conduction state, the refrigerant pressure at the inlet side of the pressure regulating structure 3 can be less than the refrigerant pressure at the outlet side of the pressure regulating structure 3, so that the refrigerant pressure in the second heat exchanger 12 is greater than the refrigerant pressure in the second vehicle refrigerator 227, and the evaporation temperature of the refrigerant in the second heat exchanger 12 is greater than the evaporation temperature of the refrigerant in the second vehicle refrigerator 227, that is, in the case that the air conditioning system 1 is normally working, the refrigeration temperature of the second vehicle refrigerator 227 is lower than the refrigeration temperature of the air conditioning system 1, so as to meet the demand of the lower refrigeration temperature of the second vehicle refrigerator 227 in the case that the second heat exchanger 12 and the second vehicle refrigerator 227 share the first compressor 14 and simultaneously refrigerate, and improve the refrigeration capacity and refrigeration speed of the second vehicle refrigerator 227.

[0191] For the above-mentioned embodiments, the pressure regulating structure 3 can be a pressure increasing valve, which can be arranged on the second refrigerator heat exchange branch 42 and located downstream of the second vehicle refrigerator 227, and in the first conduction state, the refrigerant pressure at the inlet side of the pressure increasing valve can be less than the refrigerant pressure at the outlet side of the pressure increasing valve.

[0192] Optionally, the pressure regulating structure 3 further has a second conduction state, in which the refrigerant pressure at the inlet side of the pressure regulating structure 3 is the same as the refrigerant pressure at the outlet side of the pressure regulating structure 3. In the second conduction state, the refrigerant pressures at the inlet and outlet of the pressure regulating structure 3 are the same, and the pressure regulating structure 3 can be regarded as a through-flow pipeline, at this time, the refrigerant pressures in the parallel-connected second heat exchanger 12 and second vehicle refrigerator 227 are the same, and the evaporation temperatures of the refrigerants are also the same.

[0193] When the vehicle refrigerator 22 has high demand and the air conditioner has low demand, the pressure regulating structure 3 can be in the first conduction state to preferentially meet the refrigeration demand of the second vehicle refrigerator 227; when the second vehicle refrigerator 227 has low demand and the air conditioner has high demand, the pressure regulating structure 3 can be in the second conduction state to preferentially meet the refrigeration demand of the air conditioning system 1.

[0194] Optionally, in the first conduction state, the absolute value of the difference between the refrigerant pressure at the inlet side of the pressure regulating structure 3 and the refrigerant pressure at the outlet side of the pressure regulating structure 3 is 150 kPa-200 kPa. When the difference between the refrigerant pressures is within this range, the refrigeration temperature of the second vehicle refrigerator 227 can be as low as possible while ensuring that the air conditioning system 1 is normally working, so as to meet the refrigeration demand of the vehicle refrigerator 22.

[0195] To improve the intelligent degree of the vehicle thermal management system 100, the air conditioning system 1 optionally further comprises a first temperature and pressure sensor 13 located downstream of the second heat exchanger 12, and the vehicle thermal management system 100 further comprises a second temperature and pressure sensor 25 located downstream of the second vehicle refrigerator 227. The vehicle thermal management system 100 further comprises a controller, and the first temperature and pressure sensor 13, the second temperature and pressure sensor 25, and the pressure regulating structure 3 are all electrically connected to the controller.

[0196] The first temperature and pressure sensor 13 can detect the pressure and temperature of the refrigerant in the second heat exchanger 12, and the second temperature and pressure sensor 25 can detect the pressure and temperature of the refrigerant in the second vehicle refrigerator 227, and transmit the measured pressure and temperature information to the controller. The controller can adjust the difference between the refrigerant pressure at the inlet side of the pressure regulating structure 3 and the refrigerant pressure at the outlet side of the pressure regulating structure 3 according to the obtained pressure and temperature data, so that the air conditioning system 1 and the second vehicle refrigerator 227 can both operate at the required refrigeration temperature.

[0197] As shown in FIG. 7 and FIG. 1, in the third and fourth embodiments provided by the present disclosure, at least two of the plurality of refrigerator heat exchange flow paths 4 are connected in parallel with each other, that is, at least two of the plurality of vehicle refrigerators 22 are connected in parallel with each other. The vehicle refrigerators 22 connected in parallel with each other can have refrigeration function or heating function at the same time through the refrigerant.

[0198] It can be understood that for the embodiment in which each vehicle refrigerator 22 comprises a refrigerator heat exchanger 223 for heat exchange with the article storage space of the vehicle refrigerator 22, at least two of the plurality of refrigerator heat exchangers 223 are connected in parallel with each other, that is, the outlet of the first compressor 14 is connected to the inlet of at least one refrigerator heat exchanger 223, and the outlet of at least two refrigerator heat exchangers 223 is connected to the inlet of the first compressor 14.

[0199] The above-mentioned refrigerator heat exchanger 223 can be used as an evaporator to cool the air in the article storage space to meet the needs of refrigerating or freezing the articles in the article storage space. The above-mentioned refrigerator heat exchanger 223 can also be used as a condenser to heat the air in the article storage space to heat and keep warm the articles in the article storage space. The present disclosure does not limit whether the refrigerator heat exchanger 223 is used as an evaporator or a condenser, or whether it can be used as an evaporator when there is a refrigeration demand and as a condenser when there is a heating demand.

[0200] For example, in the third embodiment provided by the present disclosure, as shown in FIG. 7, the vehicle thermal management system 100 further comprises a refrigerator expansion valve 26, the refrigerator expansion valve 26 is arranged on the refrigerator heat exchange flow path 4 in parallel with each other, and the refrigerator expansion valve 26 is located downstream of the vehicle refrigerator 22 (i.e. the refrigerant first flows through the vehicle refrigerator 22, and then flows through the refrigerator expansion valve 26).

[0201] In the third embodiment, the vehicle refrigerator 22 is used to realize the heating or heat preservation function of the stored articles (i.e. the refrigerator heat exchanger 223 is used as a condenser), and the refrigerant discharged at the vehicle refrigerator 22 can be throttled and decompressed by the refrigerator expansion valve 26 to become low-temperature and low-pressure gaseous refrigerant, which can be heated and then returned to the first compressor 14.

[0202] Optionally, in the third embodiment described above, as shown in FIG. 7, the vehicle thermal management system 100 further comprises an air conditioning system 1, the air conditioning system 1 comprises the first heat exchanger 15, an air conditioning refrigerant flow path 5 and the first compressor 14, the air conditioning refrigerant flow path 5 comprises a first air conditioning refrigerant branch 51 and a second air conditioning refrigerant branch 52, and the first heat exchanger 15 is arranged on the first air conditioning refrigerant branch 51.

[0203] The second air conditioning refrigerant branch 52 is connected in parallel with at least two refrigerator heat exchange flow paths 4 of the plurality of refrigerator heat exchange flow paths 4, one end of the first air conditioning refrigerant branch 51 is connected with the first compressor 14, the other end of the first air conditioning refrigerant branch 51 is connected with one end of the second air conditioning refrigerant branch 52 and one end of the at least two refrigerator heat exchange flow paths 4, and the other end of the second air conditioning refrigerant branch 52 and the other end of the at least two refrigerator heat exchange flow paths 4 are connected with the first compressor 14. Specifically, the outlet of the first air conditioning refrigerant branch 51 is connected with the inlet of the first compressor 14, the inlet of the first air conditioning refrigerant branch 51 is connected with the outlet of the second air conditioning refrigerant branch 52 and the outlet of the at least two refrigerator heat exchange flow paths 4, and the inlet of the second air conditioning refrigerant branch 52 and the inlet of the at least two refrigerator heat exchange flow paths 4 are connected with the outlet of the first compressor 14.

[0204] Through the above technical solution, the first compressor 14, the second air conditioning refrigerant branch 52 and the first heat exchanger 15 are connected in series to form a loop, and the first compressor 14, the vehicle refrigerator 22, the refrigerator expansion valve 26 and the first heat exchanger 15 are connected in series to form another loop. The refrigerant discharged from the outlet of the first compressor 14 is heated at the equipment (e.g. the second heat exchanger 12) arranged on the second air conditioning refrigerant branch 52 or is heated at the vehicle refrigerator 22, the refrigerant discharged after heating is throttled and decompressed by the air conditioning expansion valve 16 or the refrigerator expansion valve 26, and then is heated at the first heat exchanger 15, and finally returns to the first compressor 14.

[0205] Optionally, the air conditioning system 1 further comprises a second heat exchanger 12 and an air conditioning expansion valve 16. The second heat exchanger 12 and the air conditioning expansion valve 16 are both arranged on the second air conditioning refrigerant branch 52, and the air conditioning expansion valve 16 is located downstream of the second heat exchanger 12. Here, the second heat exchanger 12 can be an indoor condenser, and the first heat exchanger 15 can be an outdoor heat exchanger.

[0206] For the embodiment in which the vehicle refrigerator 22 comprises the refrigerator heat exchanger 223, the outlet of the first compressor 14 is connected with the inlets of the plurality of refrigerator heat exchangers 223, the outlet of each refrigerator heat exchanger 223 is connected with the inlet of a corresponding refrigerator expansion valve 26, the outlets of the plurality of refrigerator expansion valves 26 are connected with the inlet of the first heat exchanger 15, and the outlet of the first heat exchanger 15 is connected with the inlet of the first compressor 14. Thus, the refrigerant in the refrigerator heat exchanger 223 can be used to heat the article storage space of the vehicle refrigerator 22, so as to realize the heating function of the vehicle refrigerator 22.

[0207] In the fourth implementation provided in the present disclosure, as shown in FIG. 1, the vehicle thermal management system 100 further comprises a refrigerator expansion valve 26, which is located upstream of the vehicle refrigerator 22 (i.e., the refrigerant first flows through the refrigerator expansion valve 26 and then flows through the vehicle refrigerator 22).

[0208] In the fourth implementation, the vehicle refrigerator 22 is used to realize the refrigeration or freezing function of the articles stored therein (i.e., the refrigerator heat exchanger 223 is used as an evaporator), and the refrigerant first throttles and depressurizes through the refrigerator expansion valve 26, and then returns to the first compressor 14 after absorbing heat at the vehicle refrigerator 22.

[0209] Optionally, in the fourth implementation, as shown in FIG. 1, the vehicle thermal management system 100 further comprises an air conditioning system 1, the air conditioning system 1 comprises the first heat exchanger 15, an air conditioning refrigerant flow path 5 and the first compressor 14, the air conditioning refrigerant flow path 5 comprises a first air conditioning refrigerant branch 51 and a second air conditioning refrigerant branch 52, and the first heat exchanger 15 is arranged on the first air conditioning refrigerant branch 51. The second air conditioning refrigerant branch 52 is connected in parallel with at least two of the plurality of refrigerator heat exchange flow paths 4, one end of the first air conditioning refrigerant branch 51 is connected with the first compressor 14, the other end of the first air conditioning refrigerant branch 51 is connected with one end of the second air conditioning refrigerant branch 52 and one end of the at least two refrigerator heat exchange flow paths 4, and the other end of the second air conditioning refrigerant branch 52 and the other end of the at least two refrigerator heat exchange flow paths 4 are connected with the first compressor 14. Specifically, the inlet of the first air conditioning refrigerant branch 51 is connected with the outlet of the first compressor 14, the outlet of the first air conditioning refrigerant branch 51 is connected with the inlet of the second air conditioning refrigerant branch 52 and the inlet of the at least two refrigerator heat exchange flow paths 4, and the outlet of the second air conditioning refrigerant branch 52 and the outlet of the at least two refrigerator heat exchange flow paths 4 are connected with the inlet of the first compressor 14.

[0210] By the above technical solution, the first compressor 14, the first heat exchanger 15 and the second air-conditioning refrigerant branch 52 are sequentially connected in series to form a loop, and the first compressor 14, the first heat exchanger 15, the refrigerator expansion valve 26 and the vehicle refrigerator 22 are sequentially connected in series to form another loop. The refrigerant flowing out of the outlet of the first compressor 14 releases heat at the first heat exchanger 15, and the refrigerant after heat release can absorb heat at the second air-conditioning refrigerant branch 52 or the vehicle refrigerator 22, and finally returns to the first compressor 14.

[0211] Optionally, the air conditioning system 1 further comprises a second heat exchanger 12 and an air-conditioning expansion valve 16, both of which are arranged on the second air-conditioning refrigerant branch 52, and the air-conditioning expansion valve 16 is located upstream of the second heat exchanger 12. Here, the first heat exchanger 15 can be an outdoor heat exchanger, and the second heat exchanger 12 can be an indoor evaporator, which is used to realize the refrigeration of the passenger compartment.

[0212] As shown in FIG. 1, for the embodiment in which the vehicle refrigerator 22 comprises a refrigerator heat exchanger 223, a plurality of refrigerator expansion valves 26 correspond to a plurality of refrigerator heat exchangers 223 one by one. When refrigeration is performed by the refrigerator heat exchanger 223, the outlet of the first compressor 14 is connected to the inlet of the first heat exchanger 15, the outlet of the first heat exchanger 15 is connected to the inlets of the plurality of refrigerator expansion valves 26, and the outlet of each refrigerator expansion valve 26 is connected to the inlet of the corresponding refrigerator heat exchanger 223. The first compressor 14, the first heat exchanger 15, the refrigerator expansion valve 26 and the refrigerator heat exchanger 223 can be sequentially connected in series to form a refrigerant loop, and the high-temperature and high-pressure gaseous refrigerant discharged from the first compressor 14 flows into the first heat exchanger 15 and releases heat to the atmosphere in the first heat exchanger 15, and the refrigerant after heat release is throttled and depressurized by the refrigerator expansion valve 26 to become low-temperature and low-pressure liquid refrigerant, which enters the refrigerator heat exchanger 223, thereby absorbing the temperature of the air in the article storage space in the refrigerator heat exchanger 223 to realize the refrigeration or freezing function of the vehicle refrigerator 22.

[0213] The above-mentioned refrigerator expansion valve 26 can control the opening and closing of the refrigerant flow path in which the refrigerator heat exchanger 223 is located, that is, control whether the refrigerant flowing out of the outlet of the first heat exchanger 15 can enter the refrigerator heat exchanger 223 or not, so that the plurality of refrigerator heat exchangers 223 can be operated simultaneously or only partially, and on the other hand, the refrigerator expansion valve 26 can also adjust the evaporation pressure and evaporation temperature of the refrigerant entering the corresponding refrigerator heat exchanger 223, so that the article storage spaces of the plurality of vehicle refrigerators 22 can have different preservation temperatures.

[0214] To enrich the functionality of the vehicle refrigerator 22, as one implementation, the vehicle refrigerator 22 may also include a heating element 225, which is used to heat the air in the item storage space. When the refrigerator heat exchanger 223 is used as an evaporator to cool the item storage space, if the user wants to heat the items stored in the item storage space, the first compressor 14 and the refrigerator heat exchanger 223 do not need to be started. Instead, the air in the item storage space is heated by the heating element 225, thereby ensuring that the air in the item storage space can maintain a certain temperature to heat or keep the items warm.

[0215] Furthermore, when a user has a cooling need for one of the multiple vehicle refrigerators 22 and a heating need for another vehicle refrigerator 22, the refrigerator heat exchanger 223 corresponding to one vehicle refrigerator 22 can be activated to cool the storage space of the items inside that vehicle refrigerator 22, while the refrigerator heat exchanger 223 corresponding to the other vehicle refrigerator 22 is turned off and the heating element 225 corresponding to the other vehicle refrigerator 22 is turned on, thereby achieving the effect of one vehicle refrigerator 22 cooling and another vehicle refrigerator 22 heating.

[0216] In addition, when the refrigerator heat exchanger 223 is used as a condenser to heat the storage space, if the user wants to quickly increase the temperature of the storage space, the refrigerator heat exchanger 223 and the heating element 225 can be turned on at the same time to increase the heating rate of the storage space.

[0217] As another implementation, the vehicle refrigerator 22 may also include a cooling element for cooling the air in the item storage space. When the refrigerator heat exchanger 223 is used as a condenser to heat the item storage space, if the user wants to cool the items stored in the item storage space, the first compressor 14 and the refrigerator heat exchanger 223 can be turned on, and the air in the item storage space can be cooled by the cooling element to refrigerate or freeze the items.

[0218] Furthermore, when a user has a cooling need for one of the multiple vehicle refrigerators 22 and a heating need for another vehicle refrigerator 22, the refrigerator heat exchanger 223 corresponding to one vehicle refrigerator 22 can be activated to heat the storage space of the items inside that vehicle refrigerator 22, while the refrigerator heat exchanger 223 corresponding to the other vehicle refrigerator 22 is turned off and the cooling component corresponding to the other vehicle refrigerator 22 is turned on, thereby achieving the effect of one vehicle refrigerator 22 heating and the other vehicle refrigerator 22 cooling.

[0219] In addition, when the refrigerator heat exchanger 223 is used as an evaporator to cool the storage space, if the user wants to quickly lower the temperature of the storage space, the refrigerator heat exchanger 223 and the cooling unit can be turned on at the same time to increase the cooling speed of the storage space.

[0220] Optionally, as shown in FIG. 4, the inlet of the first air-conditioning refrigerant branch 51 is connected with the first compressor 14, the outlet of the first air-conditioning refrigerant branch 51 is connected with the inlet of the second air-conditioning refrigerant branch 52 and the inlet of the at least two refrigerator heat exchange flow paths 4, and the outlet of the second air-conditioning refrigerant branch 52 and the outlet of the at least two refrigerator heat exchange flow paths 4 are connected with the inlet of the first compressor 14. The vehicle thermal management system 100 further comprises a pressure regulating structure 3, which is arranged on the second air-conditioning refrigerant branch 52 and close to the outlet of the second air-conditioning refrigerant branch 52 (for example, the pressure regulating structure 3 can be located downstream of the second heat exchanger 12), or the pressure regulating structure 3 is arranged on at least one of the refrigerator heat exchange flow paths 4 which are in parallel with each other and close to the outlet of the refrigerator heat exchange flow path.

[0221] The pressure regulating structure 3 has a first conduction state, in which the refrigerant pressure on the inlet side of the pressure regulating structure 3 is different from the refrigerant pressure on the outlet side of the pressure regulating structure 3, so that the refrigerant pressure in the second heat exchanger 12 is different from the refrigerant pressure in the vehicle-mounted refrigerator 22.

[0222] It should be noted that the pressure regulating structure 3 arranged on at least one of the refrigerator heat exchange flow paths 4 which are in parallel with each other means that the pressure regulating structure 3 can be arranged on all of the refrigerator heat exchange flow paths 4 which are in parallel with each other, or the pressure regulating structure 3 can be arranged on any one of the refrigerator heat exchange flow paths 4 which are in parallel with each other, or the pressure regulating structure 3 can be arranged on at least two of the refrigerator heat exchange flow paths 4 which are in parallel with each other.

[0223] For the embodiment in which the pressure regulating structure 3 is arranged on the air-conditioning refrigerant flow path 5 and close to the outlet of the air-conditioning refrigerant flow path 5, and the inlet of the pressure regulating structure 3 is connected with the outlet of the second heat exchanger 12, the refrigerant pressure at the inlet of the pressure regulating structure 3 is equal to or substantially equal to the refrigerant pressure in the second heat exchanger 12, and since the second heat exchanger 12 is in parallel with the vehicle-mounted refrigerator 22, the outlet of the pressure regulating structure 3 is in communication with the outlet of the vehicle-mounted refrigerator 22, and the refrigerant pressure at the outlet of the pressure regulating structure 3 is equal to or substantially equal to the refrigerant pressure at the outlet of the vehicle-mounted refrigerator 22.

[0224] Similarly, for the embodiment that the pressure regulating structure 3 is arranged in at least one of the refrigerator heat exchange flow paths 4 in parallel with the refrigerator 22 and close to the outlet of the refrigerator heat exchange flow path 4, and the inlet of the pressure regulating structure 3 is connected with the outlet of the refrigerator 22, the refrigerant pressure at the inlet of the pressure regulating structure 3 is equal to or substantially equal to the refrigerant pressure in the refrigerator 22, and since the second heat exchanger 12 is in parallel with the refrigerator 22, the outlet of the pressure regulating structure 3 is in communication with the outlet of the second heat exchanger 12, and the refrigerant pressure at the outlet of the pressure regulating structure 3 is equal to or substantially equal to the refrigerant pressure at the outlet of the second heat exchanger 12.

[0225] The refrigerant pressure in the second heat exchanger 12 (i.e. the evaporation pressure of the refrigerant) is positively correlated with the evaporation temperature of the refrigerant, i.e. the smaller the refrigerant pressure, the lower the evaporation temperature of the refrigerant. By adjusting the refrigerant pressures at the inlet side and the outlet side of the pressure regulating structure 3, the refrigerant pressures in the second heat exchanger 12 and the refrigerator 22 can be adjusted, so that the refrigerant pressures in the second heat exchanger 12 and the refrigerator 22 are different, thereby making the evaporation temperatures of the refrigerants in the second heat exchanger 12 and the refrigerator 22 different, so that the second heat exchanger 12 and the refrigerator 22 can have different cooling speeds to meet the different temperature requirements of the user for the temperature of the passenger compartment and the temperature in the refrigerator 22, for the differentiated requirements of the target temperature when the refrigerator 22 and the air conditioning system 1 are used at the same time.

[0226] Optionally, for the embodiment that the inlet of the pressure regulating structure 3 is connected with the outlet of the second heat exchanger 12, in the first conduction state, the refrigerant pressure at the inlet side of the pressure regulating structure 3 can be greater than the refrigerant pressure at the outlet side of the pressure regulating structure 3, so that the refrigerant pressure in the second heat exchanger 12 is greater than the refrigerant pressure in the refrigerator 22. Since in the first conduction state, the refrigerant pressure in the second heat exchanger 12 is greater than the refrigerant pressure in the refrigerator 22, thereby making the evaporation temperature of the refrigerant in the second heat exchanger 12 greater than the evaporation temperature of the refrigerant in the refrigerator 22, i.e. in the case that the air conditioning system 1 is normally working, the refrigeration temperature of the refrigerator 22 is lower than the refrigeration temperature of the air conditioning system 1, thereby meeting the requirement of the lower refrigeration temperature of the refrigerator 22 in the case that the second heat exchanger 12 and the refrigerator 22 share the first compressor 14 and the second heat exchanger 12 and the refrigerator 22 refrigerate at the same time, and improving the refrigeration capacity and the refrigeration speed of the refrigerator 22.

[0227] For the above embodiments, the pressure regulating structure 3 can be a throttle valve, which can be arranged on the air-conditioning refrigerant flow path 5 and located downstream of the second heat exchanger 12, so that in the first conduction state, the refrigerant pressure on the inlet side of the throttle valve can be greater than the refrigerant pressure on the outlet side of the throttle valve. The throttle valve can adjust the amount of refrigerant passing through the throttle valve by adjusting the opening degree of the throttle valve, so that the refrigerant pressures on the inlet and outlet sides of the throttle valve are different. In other embodiments, the pressure regulating structure 3 can also be a pressure regulating valve, a flow regulating valve, etc.

[0228] Optionally, for the embodiment in which the inlet of the pressure regulating structure 3 is connected to the outlet of the vehicle-mounted refrigerator 22, in the first conduction state, the refrigerant pressure on the inlet side of the pressure regulating structure 3 can be less than the refrigerant pressure on the outlet side of the pressure regulating structure 3, so that the refrigerant pressure in the second heat exchanger 12 is greater than the refrigerant pressure in the vehicle-mounted refrigerator 22, and the evaporation temperature of the refrigerant in the second heat exchanger 12 is greater than the evaporation temperature of the refrigerant in the vehicle-mounted refrigerator 22, i.e., in the case of normal operation of the air-conditioning system 1, the refrigeration temperature of the vehicle-mounted refrigerator 22 is lower than the refrigeration temperature of the air-conditioning system 1, thereby meeting the demand for lower refrigeration temperature of the vehicle-mounted refrigerator 22 in the case of simultaneous refrigeration of the second heat exchanger 12 and the vehicle-mounted refrigerator 22 using the first compressor 14, and improving the refrigeration capacity and refrigeration speed of the vehicle-mounted refrigerator 22.

[0229] For the above embodiments, the pressure regulating structure 3 can be a pressure increasing valve, which can be arranged on the second refrigerator heat exchanger branch 42 and located downstream of the vehicle-mounted refrigerator 22, so that in the first conduction state, the refrigerant pressure on the inlet side of the pressure increasing valve can be less than the refrigerant pressure on the outlet side of the pressure increasing valve.

[0230] Optionally, the pressure regulating structure 3 also has a second conduction state, in which the refrigerant pressure on the inlet side of the pressure regulating structure 3 is the same as the refrigerant pressure on the outlet side of the pressure regulating structure 3. In the second conduction state, the refrigerant pressures at the inlet and outlet of the pressure regulating structure 3 are the same, and the pressure regulating structure 3 can be regarded as a through-flow pipe. At this time, the refrigerant pressures in the parallel-connected second heat exchanger 12 and vehicle-mounted refrigerator 22 are the same, and the evaporation temperatures of the refrigerant are also the same.

[0231] When the vehicle-mounted refrigerator 22 has high demand and the air conditioner has low demand, the pressure regulating structure 3 can be in the first conduction state to preferentially meet the refrigeration demand of the vehicle-mounted refrigerator 22; when the vehicle-mounted refrigerator 22 has low demand and the air conditioner has high demand, the pressure regulating structure 3 can be in the second conduction state to preferentially meet the refrigeration demand of the air-conditioning system 1.

[0232] Optionally, in the first conduction state, the absolute value of the difference between the refrigerant pressure on the inlet side of the pressure regulating structure 3 and the refrigerant pressure on the outlet side of the pressure regulating structure 3 is 150-200 kPa. When the difference in refrigerant pressure is within this range, the refrigeration temperature of the vehicle refrigerator 22 can be lowered as much as possible while ensuring the normal operation of the air conditioning system 1, thereby meeting the refrigeration needs of the vehicle refrigerator 22.

[0233] To improve the intelligence of the vehicle thermal management system 100, optionally, as shown in FIG. 1, the air conditioning system 1 further comprises a first temperature and pressure sensor 13 located downstream of the second heat exchanger 12, and the vehicle thermal management system 100 further comprises a second temperature and pressure sensor 25 located downstream of the vehicle refrigerator 22. The vehicle thermal management system 100 further comprises a controller, and the first temperature and pressure sensor 13, the second temperature and pressure sensor 25, and the pressure regulating structure 3 are all electrically connected to the controller.

[0234] The first temperature and pressure sensor 13 can detect the refrigerant pressure and temperature in the second heat exchanger 12, and the second temperature and pressure sensor 25 can detect the refrigerant pressure and temperature in the vehicle refrigerator 22, and transmit the measured pressure and temperature information to the controller. The controller can adjust the difference between the refrigerant pressure on the inlet side of the pressure regulating structure 3 and the refrigerant pressure on the outlet side of the pressure regulating structure 3 according to the obtained pressure and temperature data, so that the air conditioning system 1 and the vehicle refrigerator 22 can both operate at the refrigeration temperature required by the user.

[0235] Optionally, the refrigerator expansion valve 26 in the above embodiments can be integrated on the vehicle refrigerator 22, the refrigerator expansion valve 26 can be installed outside the vehicle refrigerator 22 and connected to the heat exchange structure (such as the refrigerator heat exchanger 223) in the vehicle refrigerator 22 through a pipeline, or can be installed inside the vehicle refrigerator 22, such as at the inlet or outlet of the heat exchange structure in the vehicle refrigerator 22, and the specific installation position of the refrigerator expansion valve 26 is not limited in the present disclosure.

[0236] To improve the heat exchange effect of the refrigerator heat exchanger 223 and the air in the article containing space, optionally, as shown in FIG. 8, the refrigerator heat exchanger 223 comprises a heat exchange pipe 221 and a heat exchange shell 222, the inner surface of the heat exchange shell 222 defines an article containing space, the outlet of the first compressor 14 is connected to the inlet of the heat exchange pipe 221, the outlet of the heat exchange pipe 221 is connected to the inlet of the first compressor 14, and the heat exchange pipe 221 is in thermal contact with the outer surface of the heat exchange shell 222, so that the refrigerant in the heat exchange pipe 221 can directly exchange heat with the air in the article containing space through the heat exchange shell 222.

[0237] The inlet and outlet of the first compressor 14 are connected with the outlet and inlet of the heat exchange pipe 221, and the heat exchange pipe 221 can be provided with the refrigerant for heat exchange. The heat exchange pipe 221 is in heat conduction contact with the outer surface of the heat exchange shell 222, and the inner surface of the heat exchange shell 222 defines an article containing space. The heat exchange shell 222 can be directly in contact with the air in the article containing space, so that the cold or heat of the refrigerant in the heat exchange pipe 221 can be directly conducted to the heat exchange shell 222 through the heat exchange pipe 221, and heat exchange with the air in the article containing space through the heat exchange shell 222, reducing the loss of cold or heat in the conduction process, and improving the refrigeration or heating efficiency of the vehicle-mounted refrigerator 22.

[0238] Optionally, the heat conduction coefficient of the heat exchange shell 222 can be 201 W / mk-237 W / mk. The material with this coefficient has good heat conduction performance and can meet the heat exchange demand of the heat exchange pipe 221 for heat exchange with the air in the article containing space through the heat exchange shell 222.

[0239] The specific material of the heat exchange shell 222 is not limited in the present disclosure, for example, the material of the heat exchange shell 222 can be aluminum or copper.

[0240] As mentioned above, the vehicle-mounted refrigerator 22 can include a heating element 225, as shown in FIG. 8, in an embodiment provided by the present disclosure, the heating element 225 can include a heating film, and the heating film is covered on the outer surface of the heat exchange shell 222 and / or the side of the heat exchange pipe 221 away from the heat exchange shell 222.

[0241] For the above-mentioned embodiment of the vehicle-mounted refrigerator 22 including a cooling element, the cooling element can include a semiconductor refrigeration sheet, and the semiconductor refrigeration sheet is covered on the outer surface of the heat exchange shell 222 and / or the side of the heat exchange pipe 221 away from the heat exchange shell 222.

[0242] The heating film or semiconductor refrigeration sheet covered on the outer surface of the heat exchange shell 222 can directly exchange heat with the heat exchange shell 222, and exchange heat with the air in the article containing space through the heat exchange shell 222, reducing the heat loss in the heating or refrigeration process.

[0243] The heating film or semiconductor refrigeration sheet covered on the side of the heat exchange pipe 221 away from the heat exchange shell 222 can not only exchange heat with the air in the article containing space through the heat exchange pipe 221 and the heat exchange shell 222, but also can press the heat exchange pipe 221 tightly on the heat exchange shell 222, to ensure the heat conduction contact between the heat exchange pipe 221 and the heat exchange shell 222.

[0244] To further improve the heat exchange efficiency, the vehicle refrigerator 22 can optionally comprise a fan 224, as shown in FIG. 1, which is configured to accelerate the airflow in the article containing space. For example, the fan 224 can be configured to generate airflow that can exchange heat with the refrigerant in the heat exchange pipe 221 and enter the article containing space. The fan 224 can accelerate the flow between the air near the heat exchange pipe 221 and the air in the article containing space, thereby improving the heat exchange efficiency between the heat exchange pipe 221 and the air in the article containing space, and improving the heating or cooling speed of the vehicle refrigerator 22. It can be understood that when the heating element 225 is used for heating or the cooling element is used for cooling, the fan 224 can accelerate the flow between the air near the heating element 225 or the cooling element and the air in the article containing space, thereby improving the heat exchange efficiency between the heating element 225 or the cooling element and the air in the article containing space, and improving the heating or cooling speed of the vehicle refrigerator 22.

[0245] Optionally, the heat exchange shell 222 is provided with an air inlet, and the fan 224 is arranged at the air inlet. The air inlet is arranged on the heat exchange shell 222 to accommodate the fan 224, so that the fan 224 does not occupy the volume of the article containing space. At the same time, the air inlet also enables the fan 224 to directly drive the air on both sides of the air inlet to flow relative to each other, forming a convection, thereby improving the heat exchange efficiency of the heat exchange pipe 221.

[0246] Optionally, as shown in FIG. 1, the air conditioning system 1 further comprises a gas-liquid separator 17, an inlet of the gas-liquid separator 17 is connected with outlets of the plurality of refrigerator heat exchangers 223 and the second heat exchanger 12, and an outlet of the gas-liquid separator 17 is connected with an inlet of the first compressor 14. The refrigerant flowing out of the outlets of the refrigerator heat exchangers 223 and the second heat exchanger 12 passes through the gas-liquid separator 17 before returning to the first compressor 14, so that the liquid and the gas in the refrigerant can be separated, thereby enabling the gas refrigerant to return to the first compressor 14 to prevent the first compressor 14 from being damaged.
