DETAILED DESCRIPTION

[0057] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0058] In this disclosure, unless otherwise indicated, directional terms such as "upstream" and "downstream" are generally defined based on the direction of refrigerant flow, and "inside" and "outside" refer to the inside and outside of the contours of the corresponding components. Furthermore, the terms "first" and "second" are used solely for distinction and description and should not be construed as indicating or implying relative importance.

[0059] It should also be noted that, in the description of this disclosure, unless otherwise expressly specified or limited, the terms "disposed," "connected," "connected," and "installed" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; and they may refer to direct connections or indirect connections via an intermediary. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on specific circumstances.

[0060] According to the first aspect of the present disclosure, Figures 1 to 5 As shown, the present disclosure provides a vehicle thermal management system 100, including a first compressor 14, an air conditioner refrigerant flow path 5, and multiple refrigerator heat exchange flow paths 4, with an onboard refrigerator 22 disposed 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 multiple refrigerator heat exchange flow paths 4 is connected to the first compressor 14.

[0061] Here, the vehicle refrigerator 22 is provided on the above-mentioned refrigerator heat exchange flow path 4, which means that the heat exchange pipe or heat exchange component of the vehicle refrigerator 22 through which the heat exchange medium (for example, refrigerant) 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 pipe or heat exchange component of the vehicle refrigerator 22, and exchange heat with the item storage space in the vehicle refrigerator 22 before flowing out of the vehicle refrigerator 22.

[0062] With this technical solution, since multiple vehicle refrigerators 22 each have independent storage spaces, the vehicle's storage space can be increased, allowing for more items with specific storage temperature requirements to be stored. Furthermore, multiple vehicle refrigerators 22 can be installed in different locations within the vehicle's passenger compartment, making it easier for users in different locations to access items within the vehicle refrigerators 22. Since each vehicle refrigerator 22 has a corresponding refrigerator heat exchange flow path 4, each storage space can have a different storage temperature, meeting the varying storage temperature requirements of different foods.

[0063] In addition, the air-conditioning refrigerant flow path 5 and the multiple refrigerator heat exchange flow paths 4 are all connected to the same first compressor 14, which can increase the vehicle storage space and meet the user's needs for different storage temperatures for different foods without increasing the vehicle cost too much or occupying too much vehicle volume.

[0064] It will be appreciated that in order for the refrigerant to flow into the vehicle refrigerator 22 and exchange heat with the storage space within the vehicle refrigerator 22, the vehicle refrigerator 22 has a passage for the refrigerant to flow through. For example, the vehicle refrigerator 22 may be provided with a refrigerant heat exchange channel, a refrigerant heat exchange chamber, a refrigerant heat exchange pipe, or a heat exchanger (such as the refrigerator heat exchanger 223 mentioned below) within the vehicle refrigerator 22. The present disclosure does not limit the specific method for heat exchange between the refrigerant and the storage space within the vehicle refrigerator 22; as long as the refrigerant can flow into the vehicle refrigerator 22 and exchange heat with the storage space within the vehicle refrigerator 22, it is sufficient.

[0065] 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, it can heat the storage space of the vehicle refrigerator 22 or cool the storage space of the vehicle refrigerator 22, and this disclosure is not limited to this. Moreover, for multiple refrigerator heat exchange flow paths 4, the refrigerant in the multiple refrigerator heat exchange flow paths 4 can release heat or absorb heat after flowing into the corresponding vehicle refrigerator 22, that is, the multiple vehicle refrigerators 22 can all be in heating mode or in cooling mode; or, some of the multiple refrigerator heat exchange flow paths 4 can release heat after flowing into the corresponding vehicle refrigerator 22, while other parts of the refrigerator heat exchange flow paths 4 can absorb heat after flowing into the corresponding vehicle refrigerator 22, that is, some of the multiple vehicle refrigerators 22 can be in heating mode and other parts of the vehicle refrigerators 22 can be in cooling mode, and this disclosure is not limited to this.

[0066] In other words, for the embodiment in which the vehicle refrigerator 22 has a refrigerator heat exchanger 223, the refrigerator heat exchanger 223 can be used as an evaporator to cool the air in the item storage space to meet the needs of refrigerating or freezing the items in the item storage space. The refrigerator heat exchanger 223 can also be used as a condenser to heat the air in the item storage space to heat and keep the items in the item storage space warm. The present disclosure does not limit whether the refrigerator heat exchanger 223 is specifically used as an evaporator or a condenser, or whether it can be used as an evaporator when there is a cooling demand and as a condenser when there is a heating demand.

[0067] Furthermore, at least one of the plurality of refrigerator heat exchange flow paths 4 may be connected to the first compressor 14, only one of the plurality of refrigerator heat exchange flow paths 4 may be connected to the first compressor 14, or a portion (greater than or equal to two) of the plurality of refrigerator heat exchange flow paths 4 may be connected to the first compressor 14, or all of the plurality of refrigerator heat exchange flow paths 4 may be connected to the first compressor 14. This disclosure is not limited to this. If a portion of the plurality of refrigerator heat exchange flow paths 4 is not connected to the first compressor 14, the refrigerator heat exchange flow paths 4 not connected to the first compressor 14 may be connected to the second compressor.

[0068] In addition, multiple refrigerator heat exchange flow paths 4 can be connected in series or in parallel, or some refrigerator heat exchange flow paths 4 can be connected in parallel and other refrigerator heat exchange flow paths 4 can be connected in series. As long as at least one refrigerator heat exchange flow path 4 and the air-conditioning refrigerant flow path 5 are connected to the same first compressor 14, the present disclosure does not limit the specific series and parallel relationship between the multiple refrigerator heat exchange flow paths 4.

[0069] like Figure 1 and Figure 2As shown, in one embodiment provided by the present disclosure, multiple refrigerator heat exchange paths 4 are connected in series, that is, multiple vehicle refrigerators 22 are connected in series. The multiple vehicle refrigerators 22 connected in series can all be heated, all cooled, or one vehicle refrigerator 22 can be heated while another is cooled.

[0070] For example, Figure 1 and Figure 2 As shown, the multiple refrigerator heat exchange paths 4 include a first refrigerator heat exchange branch 41 and a second refrigerator heat exchange branch 42. The multiple vehicle refrigerators 22 include a first vehicle refrigerator 226 disposed on the first refrigerator heat exchange branch 41 and a second vehicle refrigerator 227 disposed 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. In other words, at least two of the multiple refrigerator heat exchange paths 4 are connected in series and connected to the first compressor 14.

[0071] In the above embodiment, the refrigerant in the first refrigerator heat exchange branch 41 can be used to release heat to the first vehicle refrigerator 226, and the refrigerant in the second refrigerator heat exchange branch 42 can be used to absorb heat from the second vehicle refrigerator 227; or, 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 release heat to the second vehicle refrigerator 227; or, the refrigerant in the first refrigerator heat exchange branch 41 is used to absorb heat from the first vehicle refrigerator 226, and the refrigerant in the second refrigerator heat exchange branch 42 is used to absorb heat from the second vehicle refrigerator 227. The present disclosure does not limit this.

[0072] In the first embodiment 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 from the second vehicle refrigerator 227. Specifically, Figure 1 As shown, the vehicle thermal management system 100 further includes 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 .

[0073] In the first embodiment described above, 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 item storage space of the first vehicle refrigerator 226 to increase the temperature of the item storage space of the first vehicle refrigerator 226, thereby achieving heating or heat preservation of the items. The refrigerant after releasing heat in the first vehicle refrigerator 226 is throttled and reduced in pressure by the refrigerator expansion valve 26 to become a low-temperature and low-pressure liquid refrigerant. The liquid refrigerant enters the second vehicle refrigerator 227 and absorbs heat from the item storage space of the second vehicle refrigerator 227 to reduce the temperature of the item storage space of the second vehicle refrigerator 227, thereby achieving refrigeration or freezing of the items.

[0074] Optionally, the first vehicle refrigerator 226 may have a cooling element for cooling the air in the item storage space of the first vehicle refrigerator 226; and / or, the second vehicle refrigerator 227 may have a heating element 225 for heating the air in the item storage space of the second vehicle refrigerator 227. Since the specific locations of the first vehicle refrigerator 226 and the second vehicle refrigerator 227 on the vehicle may be different, if the user needs the first vehicle refrigerator 226 to refrigerate or freeze items, the item storage space can be cooled by the cooling element. At this time, the refrigerant does not flow through the first vehicle refrigerator 226 (for example, the first compressor 14 is not turned on, or the first vehicle refrigerator 226 is short-circuited by the 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 keep warm, the item storage space can be heated by the heating element 225. At this time, the refrigerant does not flow through the second vehicle refrigerator 227 (for example, the first compressor 14 is not turned on, or the second vehicle refrigerator 227 is short-circuited by the short-circuit flow path, so that the refrigerant does not flow through the second vehicle refrigerator 227). By providing a cooling element on the first vehicle refrigerator 226 and / or a heating element 225 on the second vehicle refrigerator 227, the functions of the first vehicle refrigerator 226 and the second vehicle refrigerator 227 can be made more diverse, meet user needs, and enhance user experience.

[0075] Optionally, the vehicle thermal management system 100 may further include an air conditioning system 1, which includes the aforementioned air conditioning refrigerant flow path 5 and the aforementioned first compressor 14. That is, the refrigerator heat exchange flow path 4 and the air conditioning refrigerant flow path 5 share the first compressor 14 of the air conditioning system 1. The first compressor 14 connected to the vehicle refrigerator 22 is the first compressor 14 of the air conditioning system 1. First compressor 14 not only compresses and drives refrigerant in the refrigerant flow paths of devices in the air conditioning system 1 (such as the air conditioning evaporator and condenser), but also compresses and drives refrigerant in the heat exchange flow path of the vehicle refrigerator 22. This allows the same first compressor 14 to provide refrigerant to different thermal management devices.

[0076] Utilizing the first compressor 14 in the air-conditioning system 1 to provide flowing refrigerant to the refrigerator heat exchanger 223 of at least one vehicle refrigerator 22 can also improve the utilization rate of the first compressor 14, improve the integration of the vehicle thermal management system 100, reduce the number of equipment required for multiple vehicle refrigerators 22, and avoid a significant increase in cost due to the installation of multiple vehicle refrigerators 22.

[0077] Optionally, the outlet of first compressor 14 can be selectively connected or disconnected with the inlet of first refrigerator heat exchange branch 41, and selectively connected or disconnected with the inlet of air conditioner refrigerant flow path 5. In this way, first compressor 14 and air conditioner refrigerant flow path 5 can be connected in series to form a refrigerant circuit. The first compressor 14, first refrigerator heat exchange branch 41, and second refrigerator heat exchange branch 42 can also be connected in series to form a circuit. The high-temperature, high-pressure gaseous refrigerant discharged from first compressor 14 can flow into air conditioner refrigerant flow path 5 to achieve passenger compartment heating or passenger compartment cooling, or can flow into first refrigerator heat exchange branch 41 and second refrigerator heat exchange branch 42 to achieve heating of first vehicle refrigerator 226 and cooling of second vehicle refrigerator 227. The selective connection or disconnection between the outlet of first compressor 14 and the inlet of first refrigerator heat exchange branch 41, and the selective connection or disconnection between the outlet of first compressor 14 and the inlet of air conditioner refrigerant flow path 5 can be achieved using a three-way valve or two on / off valves, which are not limited in this disclosure.

[0078] Alternatively, as Figure 1 As shown, the air conditioning system 1 may further include a first heat exchanger 15, a second heat exchanger 12, and an air conditioning expansion valve 16. The first heat exchanger 15, the air conditioning expansion valve 16, and the second heat exchanger 12 are all disposed on the air conditioning refrigerant flow path 5, with the first heat exchanger 15 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. The outlet of the first compressor 14 can be selectively connected or disconnected with the inlet of the first refrigerator heat exchange branch 41 and the inlet of the air conditioning refrigerant flow path 5. The outlet of the air conditioning refrigerant flow path 5 is connected to the inlet of the first compressor 14.

[0079] In the embodiment where the air conditioning system 1 is used to heat the passenger compartment, the high-temperature, 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, thereby heating the passenger compartment. In this case, the first heat exchanger 15 can serve as an indoor condenser. The refrigerant, after releasing heat, is throttled and reduced in pressure by the air conditioning expansion valve 16 and flows into the second heat exchanger 12, where it absorbs heat. The refrigerant, after absorbing heat, ultimately returns to the first compressor 14. Here, the refrigerant can absorb heat from the outside atmosphere at the second heat exchanger 12, that is, the second heat exchanger 12 can be an outdoor heat exchanger; alternatively, the second heat exchanger 12 can also be provided in the electric drive thermal management system so that the refrigerant can absorb heat dissipated by the battery pack or motor at the second heat exchanger 12, thereby cooling the battery pack or motor.

[0080] In the embodiment where the air conditioning system 1 is used to cool the passenger compartment, the high-temperature, high-pressure gaseous refrigerant flowing out of the outlet of the first compressor 14 enters the first heat exchanger 15 to release heat. The first heat exchanger 15 can be an outdoor heat exchanger. After releasing heat, the refrigerant is throttled and reduced in pressure by the air conditioning expansion valve 16 and flows into the second heat exchanger 12. There, it absorbs heat from the passenger compartment, cooling the passenger compartment. The refrigerant, after absorbing heat, ultimately returns to the first compressor 14. In the above embodiment, the second heat exchanger 12 serves as an indoor evaporator.

[0081] like Figure 2 As shown, in the second embodiment provided by the present disclosure, at least two refrigerator heat exchange paths 4 are also connected in series, but unlike the first embodiment mentioned above, in this second embodiment, the multiple vehicle refrigerators 22 connected in series are all refrigerating.

[0082] Specifically, if Figure 2 As shown, the vehicle thermal management system 100 also includes a refrigerator expansion valve 26 and a first heat exchanger 15. 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 inlet of the first refrigerator heat exchange branch 41 via the refrigerator expansion valve 26. The outlet of the first refrigerator heat exchange branch 41 is connected to the inlet of the second refrigerator heat exchange branch 42.

[0083] 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 releasing heat is throttled and reduced in pressure by the refrigerator expansion valve 26 to become a low-temperature and low-pressure liquid refrigerant. The liquid refrigerant enters the first vehicle-mounted refrigerator 226 and absorbs heat from the item storage space of the first vehicle-mounted refrigerator 226 to lower the temperature of the item storage space of the first vehicle-mounted refrigerator 226. The refrigerant after absorbing heat in the first vehicle-mounted refrigerator 226 still has a certain cooling capacity. When entering the second vehicle-mounted refrigerator 227, it continues to absorb heat from the item storage space of the second vehicle-mounted refrigerator 227 to lower the temperature of the item storage space of the second vehicle-mounted refrigerator 227. In the above embodiment, the refrigerant absorbs the temperature of the item storage space of the first vehicle-mounted refrigerator 226 and the item storage space of the second vehicle-mounted refrigerator 227 in turn, which can realize simultaneous cooling of the first vehicle-mounted refrigerator 226 and the second vehicle-mounted refrigerator 227, and can make the first vehicle-mounted refrigerator 226 and the second vehicle-mounted refrigerator 227 have different item storage temperatures. For example, the first vehicle-mounted refrigerator 226 can freeze the items, and the second vehicle-mounted refrigerator 227 can refrigerate the items.

[0084] Here, the outlet of the second refrigerator heat exchange branch 42 may be connected to the inlet of the first compressor 14 so that the refrigerant returns to the first compressor 14 .

[0085] Optionally, the first heat exchanger 15 may be an outdoor heat exchanger, and the refrigerant releases heat to the outside atmosphere at the first heat exchanger 15 .

[0086] Optionally, the first vehicle refrigerator 226 and / or the second vehicle refrigerator 227 has a cooling element for cooling the air in the item 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 element 225 for heating the air in the item storage space of the first vehicle refrigerator 226 and / or the second vehicle refrigerator 227.

[0087] If the first vehicle refrigerator 226 and / or the second vehicle refrigerator 227 are equipped with cooling elements, the cooling elements can improve the cooling efficiency of the first vehicle refrigerator 226 and / or the second vehicle refrigerator 227 when the first vehicle refrigerator 226 and / or the second vehicle refrigerator 227 utilize a refrigerant. Furthermore, the first vehicle refrigerator 226 and / or the second vehicle refrigerator 227 can also utilize the cooling elements to achieve cooling rather than relying on a refrigerant.

[0088] In the case where the first vehicle refrigerator 226 and / or the second vehicle refrigerator 227 has a heating element 225, when the first vehicle refrigerator 226 and / or the second vehicle refrigerator 227 needs to heat items or keep items warm, the heating element 225 can be used to heat the first vehicle refrigerator 226 and / or the second vehicle refrigerator 227.

[0089] Alternatively, as Figure 2 As shown, the vehicle thermal management system 100 may also include an air conditioning system 1, which includes the aforementioned air conditioning refrigerant flow path 5, a first compressor 14, and a 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. The first heat exchanger 15 is disposed on the first air conditioning refrigerant branch 51. The outlet of the first compressor 14 is connected to the inlet of the first air conditioning refrigerant branch 51, which is in turn connected to the inlet of the second air conditioning refrigerant branch 52 and the inlet of the refrigerator expansion valve 26. The outlet of the first air conditioning refrigerant branch 51 can be selectively connected or disconnected from the inlet of the second air conditioning refrigerant branch 52. The selective connection or disconnection between the outlet of the first air conditioning refrigerant branch 51 and the inlet of the second air conditioning refrigerant branch 52 can be achieved using a switching valve, an on-off valve, or controlled by the air conditioning expansion valve 16, but this disclosure is not limited thereto.

[0090] Because the outlet of the first air-conditioning refrigerant branch 51 can be selectively connected or disconnected from the inlet of the second air-conditioning refrigerant branch 52 and selectively connected or disconnected from the inlet of the first refrigerator heat exchange branch 41 via 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 circuit. 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 circuit. In other words, the high-temperature, 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 passenger compartment heating or passenger compartment cooling, or can flow into the first refrigerator heat exchange branch 41 and the second refrigerator heat exchange branch 42 to achieve cooling of the first vehicle refrigerator 226 and the second vehicle refrigerator 227.

[0091] Optionally, the air-conditioning system 1 also includes a second heat exchanger 12 and an air-conditioning expansion valve 16, and 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 second heat exchanger 12 is located downstream of the air-conditioning expansion valve 16 (that is, the outlet of the second heat exchanger 12 is connected to the inlet of the air-conditioning expansion valve 16).

[0092] For an embodiment in which the air-conditioning system 1 is used to achieve a passenger compartment heating function, the first heat exchanger 15 can be an indoor condenser and the second heat exchanger 12 can be an outdoor heat exchanger; for an embodiment in which the air-conditioning system 1 is used to achieve a passenger compartment cooling function, the first heat exchanger 15 can be an outdoor heat exchanger and the second heat exchanger 12 can be an indoor evaporator.

[0093] Alternatively, as Figure 1 、 Figure 2 、 Figure 4 As shown, the outlet of the air conditioner refrigerant flow path 5 merges with the outlet of at least one refrigerator heat exchange flow path 4. The vehicle thermal management system also includes a pressure regulating structure 3, which is disposed on the air conditioner refrigerant flow path 5 and near the outlet of the air conditioner refrigerant flow path 5, and / or disposed on at least one refrigerator heat exchange flow path 4 and near the outlet of the refrigerator heat exchange flow path 4. The pressure regulating structure 3 is used to regulate the refrigerant pressure in the air conditioner refrigerant flow path 5 and the refrigerator heat exchange flow path 4.

[0094] Since the outlet of the air-conditioning refrigerant flow path 5 and the outlet of at least one refrigerator heat exchange flow path 4 converge, that is, the outlet of the air-conditioning refrigerant flow path 5 and the outlet of the refrigerator heat exchange flow path 4 are connected, 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 in the air-conditioning refrigerant flow path 5 located upstream of the pressure regulating structure 3; for the embodiment in which the pressure regulating structure 3 is arranged on at least one refrigerator heat exchange flow path 4 and close to the outlet of the refrigerator heat exchange flow path 4, the refrigerant pressure in the flow path in the refrigerator heat exchange flow path 4 located upstream of the pressure regulating structure 3 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.

[0095] Therefore, the pressure regulating structure 3 can adjust the refrigerant pressure of the air-conditioning refrigerant flow path 5 and the refrigerator heat exchange flow path 4, thereby adjusting the refrigerant pressure (that is, the evaporation pressure of the refrigerant) of the equipment (such as the second heat exchanger 12) arranged on the air-conditioning refrigerant flow path 5 and the vehicle refrigerator 22 arranged on the refrigerator heat exchange flow path 4, and then adjust the evaporation temperature and cooling speed of the equipment arranged on the air-conditioning refrigerant flow path 5 and the vehicle refrigerator 22.

[0096] For example, refer to Figure 1 and Figure 2As shown, 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. That is, the outlet of the air conditioning refrigerant flow path 5 and the outlet of the second refrigerator heat exchange branch 42 merge. The pressure regulating structure 3 is provided on the air conditioning refrigerant flow path 5 and near the outlet of the air conditioning refrigerant flow path 5 (for example, downstream of the second heat exchanger 12); alternatively, the pressure regulating structure 3 is provided on the second refrigerator heat exchange branch 42 and downstream of the second vehicle refrigerator 227.

[0097] Among them, the pressure regulating structure 3 has a first conduction state. In the first conduction state, 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.

[0098] 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, 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. Since the second heat exchanger 12 is connected in parallel with the second vehicle-mounted refrigerator 227, the outlet of the pressure regulating structure 3 is in a connected state with the outlet of the second vehicle-mounted 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-mounted refrigerator 227.

[0099] Similarly, for the embodiment in which the pressure regulating structure 3 is arranged on the second refrigerator heat exchange branch 42 and is located downstream of the second vehicle refrigerator 227, that is, 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. Since the second heat exchanger 12 is connected in parallel with the second vehicle refrigerator 227, the outlet of the pressure regulating structure 3 is in a connected state 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.

[0100] The refrigerant pressure (i.e., the evaporation pressure) within the second heat exchanger 12 is positively correlated with the refrigerant's evaporation temperature; that is, the lower the refrigerant pressure, the lower the evaporation temperature. By adjusting the refrigerant pressure at the inlet and outlet of the pressure regulating structure 3, the refrigerant pressure within the second heat exchanger 12 and the refrigerant pressure within the second vehicle refrigerator 227 can be adjusted. This allows the refrigerant pressure within the second heat exchanger 12 to differ from the refrigerant pressure within the second vehicle refrigerator 227, resulting in different evaporation temperatures for the refrigerant within the second vehicle refrigerator 227 and the second heat exchanger 12. This allows the second heat exchanger 12 and the second vehicle refrigerator 227 to have different cooling rates when the vehicle refrigerator 22 and the air conditioning system 1 are used simultaneously, depending on the target temperature. This allows the user to meet different temperature requirements for the passenger compartment and the temperature within the vehicle refrigerator 22.

[0101] Optionally, for an 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 on the inlet side of the pressure regulating structure 3 can be greater 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 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, 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, when the air-conditioning system 1 is operating normally, the cooling temperature of the second vehicle refrigerator 227 is lower than the cooling temperature of the air-conditioning system 1, thereby meeting the situation that the second heat exchanger 12 and the second vehicle refrigerator 227 share the first compressor 14, and the second heat exchanger 12 and the second vehicle refrigerator 227 are cooled at the same time, which can meet the lower cooling temperature requirement of the second vehicle refrigerator 227 and improve the cooling capacity and cooling speed of the second vehicle refrigerator 227.

[0102] In the above embodiment, the pressure regulating structure 3 can be a throttle valve. The throttle valve can be arranged in the air conditioning refrigerant flow path 5 and downstream of the second heat exchanger 12. 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 its opening, thereby causing the refrigerant pressure on the inlet and outlet sides of the throttle valve to differ. In other embodiments, the pressure regulating structure 3 can also be a pressure regulating valve, a flow regulating valve, etc.

[0103] Optionally, for an embodiment in which the pressure regulating structure 3 is arranged on the second refrigerator heat exchange branch 42 and is located downstream of the second vehicle refrigerator 227, that is, the inlet of the pressure regulating structure 3 is connected to the outlet of the second vehicle refrigerator 227, 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 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, when the air-conditioning system 1 is operating normally, the cooling temperature of the second vehicle refrigerator 227 is lower than the cooling temperature of the air-conditioning system 1, thereby meeting the requirement of a lower cooling temperature of the second vehicle refrigerator 227 when the second heat exchanger 12 and the second vehicle refrigerator 227 share the first compressor 14, and the second heat exchanger 12 and the second vehicle refrigerator 227 are cooled at the same time, thereby improving the cooling capacity and cooling speed of the second vehicle refrigerator 227.

[0104] For the above embodiment, the pressure regulating structure 3 can be a boosting valve, which can be arranged on the second refrigerator heat exchange branch 42 and located downstream of the second vehicle refrigerator 227. In the first conduction state, the refrigerant pressure on the inlet side of the boosting valve can be lower than the refrigerant pressure on the outlet side of the boosting valve.

[0105] 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 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 pipeline. In this case, the refrigerant pressure in the parallel second heat exchanger 12 and the second vehicle refrigerator 227 is the same, and the evaporation temperature of the refrigerant is also the same.

[0106] When the demand for the vehicle refrigerator 22 is high and the demand for the air conditioner is low, the pressure regulating structure 3 can be placed in the first conduction state to give priority to meeting the cooling demand of the second vehicle refrigerator 227; when the demand for the second vehicle refrigerator 227 is low and the demand for the air conditioner is high, the pressure regulating structure 3 can be placed in the second conduction state to give priority to meeting the cooling demand of the air conditioning system 1.

[0107] 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 refrigerant pressure difference is within this range, the cooling temperature of the second vehicle refrigerator 227 can be reduced as much as possible while ensuring normal operation of the air conditioning system 1, thereby meeting the cooling needs of the vehicle refrigerator 22.

[0108] To enhance the intelligence of vehicle thermal management system 100, air conditioning system 1 optionally further includes a first temperature and pressure sensor 13, located downstream of second heat exchanger 12. Vehicle thermal management system 100 further includes a second temperature and pressure sensor 25, located downstream of second onboard refrigerator 227. Vehicle thermal management system 100 further includes a controller, to which first temperature and pressure sensor 13, second temperature and pressure sensor 25, and pressure regulating structure 3 are all electrically connected.

[0109] 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 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 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 second vehicle refrigerator 227 can both operate at the cooling temperature required by the user.

[0110] like Figure 3-Figure 4 As shown, in the third and fourth embodiments provided by the present disclosure, at least two of the plurality of refrigerator heat exchange paths 4 are connected in parallel, that is, at least two of the plurality of vehicle refrigerators 22 are connected in parallel. The parallel-connected vehicle refrigerators 22 can simultaneously perform cooling functions or heating functions using a refrigerant.

[0111] It can be understood that for the embodiment in which each vehicle refrigerator 22 includes a refrigerator heat exchanger 223 for exchanging heat with the item storage space of the vehicle refrigerator 22, at least two refrigerator heat exchangers 223 among the multiple 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 the refrigerator heat exchanger 223, and the outlets of at least two refrigerator heat exchangers 223 are connected to the inlet of the first compressor 14.

[0112] The refrigerator heat exchanger 223 can be used as an evaporator to cool the air within the item storage space, thereby refrigerating or freezing the items within the item storage space. The refrigerator heat exchanger 223 can also be used as a condenser to heat the air within the item storage space, thereby heating and keeping the items within the item storage space warm. 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 cooling is required and as a condenser when heating is required.

[0113] For example, in the third embodiment provided by the present disclosure, Figure 3As shown, the vehicle thermal management system 100 also includes a refrigerator expansion valve 26. The refrigerator expansion valve 26 is provided on the refrigerator heat exchange flow paths 4 connected in parallel. 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).

[0114] In the third embodiment, the vehicle refrigerator 22 is used to achieve the function of heating or keeping warm the items stored therein (that is, the refrigerator heat exchanger 223 is used as a condenser). The refrigerant after releasing heat in the vehicle refrigerator 22 can be throttled and reduced in pressure by the refrigerator expansion valve 26 to become a low-temperature and low-pressure gaseous refrigerant. The low-temperature and low-pressure gaseous refrigerant can absorb heat and then return to the first compressor 14.

[0115] Optionally, in the third embodiment, Figure 3 As shown, the vehicle thermal management system 100 also includes an air-conditioning system 1, which includes a first heat exchanger 15, an air-conditioning refrigerant flow path 5 and a first compressor 14. The air-conditioning refrigerant flow path 5 includes a first air-conditioning refrigerant branch 51 and a second air-conditioning refrigerant branch 52. The first heat exchanger 15 is arranged on the first air-conditioning refrigerant branch 51.

[0116] 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 to the first compressor 14. The other end of the first air-conditioning refrigerant branch 51 is connected to one end of the second air-conditioning refrigerant branch 52 and one end of the at least two refrigerator heat exchange flow paths 4. The other end of the second air-conditioning refrigerant branch 52 and the other ends of the at least two refrigerator heat exchange flow paths 4 are connected to the compressor 14. Specifically, the outlet of the first air-conditioning refrigerant branch 51 is connected to the inlet of the first compressor 14, the inlet of the first air-conditioning refrigerant branch 51 is connected to the outlet of the second air-conditioning refrigerant branch 52 and the outlets 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 to the outlet of the compressor 14.

[0117] With 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 one loop. 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 flowing out of the outlet of the first compressor 14 releases heat at a device installed on the second air conditioning refrigerant branch 52 (such as the second heat exchanger 12) or at the vehicle refrigerator 22. After passing through the air conditioning expansion valve 16 or the refrigerator expansion valve 26 for throttling and pressure reduction, the refrigerant absorbs heat at the first heat exchanger 15 and ultimately returns to the first compressor 14.

[0118] Optionally, the air conditioning system 1 further includes a second heat exchanger 12 and an air conditioning expansion valve 16. Both the second heat exchanger 12 and the air conditioning expansion valve 16 are disposed on the second air conditioning refrigerant branch 52, with the air conditioning expansion valve 16 located downstream of the second heat exchanger 12. Here, the second heat exchanger 12 may be an indoor condenser for heating the passenger compartment, and the first heat exchanger 15 may be an outdoor heat exchanger.

[0119] In the embodiment where the vehicle refrigerator 22 includes a refrigerator heat exchanger 223, the outlet of the first compressor 14 is connected to the inlets of multiple refrigerator heat exchangers 223. The outlet of each refrigerator heat exchanger 223 is connected to the inlet of a corresponding refrigerator expansion valve 26. The outlets of the multiple 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 first compressor 14. Thus, the refrigerant in the refrigerator heat exchanger 223 can be used to heat the storage space of the vehicle refrigerator 22, thereby realizing the heating function of the vehicle refrigerator 22.

[0120] In the fourth embodiment provided by the present disclosure, Figure 4 As shown, the vehicle thermal management system 100 further includes a refrigerator expansion valve 26 , which is located upstream of the vehicle refrigerator 22 (ie, the refrigerant first flows through the refrigerator expansion valve 26 and then flows through the vehicle refrigerator 22 ).

[0121] In the fourth embodiment, the vehicle refrigerator 22 is used to realize the refrigeration or freezing function of the items stored therein (that is, the refrigerator heat exchanger 223 is used as an evaporator), and the refrigerant first passes through the refrigerator expansion valve 26 for throttling and pressure reduction, and then absorbs heat in the vehicle refrigerator 22 and returns to the first compressor 14.

[0122] Optionally, in the fourth embodiment, Figure 4As shown, the vehicle thermal management system 100 also includes an air conditioning system 1, which includes a first heat exchanger 15, an air conditioning refrigerant flow path 5, and a first compressor 14. The air conditioning refrigerant flow path 5 includes a first air conditioning refrigerant branch 51 and a second air conditioning refrigerant branch 52. The first heat exchanger 15 is disposed 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 multiple refrigerator heat exchange flow paths 4. One end of the first air conditioning refrigerant branch 51 is connected to the first compressor 14, and the other end of the first air conditioning refrigerant branch 51 is connected to one end of the second air conditioning refrigerant branch 52 and one end of the at least two refrigerator heat exchange flow paths 4. 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 to the first compressor 14. Specifically, the inlet of the first air-conditioning refrigerant branch 51 is connected to the outlet of the first compressor 14 , the outlet of the first air-conditioning refrigerant branch 51 is connected to the inlet of the second air-conditioning refrigerant branch 52 and the inlets of at least two refrigerator heat exchange flow paths 4 , and the outlet of the second air-conditioning refrigerant branch 52 and the outlets of at least two refrigerator heat exchange flow paths 4 are connected to the inlet of the first compressor 14 .

[0123] Through the above technical solution, the first compressor 14, the first heat exchanger 15, and the second air conditioning refrigerant branch 52 can be connected in series to form one loop, and the first compressor 14, the first heat exchanger 15, the refrigerator expansion valve 26, and the vehicle refrigerator 22 can be 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. After releasing heat, the refrigerant can absorb heat in the second air conditioning refrigerant branch 52 or the vehicle refrigerator 22, and ultimately return to the first compressor 14.

[0124] Optionally, the air conditioning system 1 further includes a second heat exchanger 12 and an air conditioning expansion valve 16. Both the second heat exchanger 12 and the air conditioning expansion valve 16 are disposed on the second air conditioning refrigerant branch 52, with the air conditioning expansion valve 16 located upstream of the second heat exchanger 12. Here, the first heat exchanger 15 may be an outdoor heat exchanger, and the second heat exchanger 12 may be an indoor evaporator, for cooling the passenger compartment.

[0125] like Figure 4As shown, in the embodiment where the vehicle refrigerator 22 includes a refrigerator heat exchanger 223, multiple refrigerator expansion valves 26 correspond one-to-one with the multiple refrigerator heat exchangers 223. When the refrigerator heat exchanger 223 is used for cooling, the outlet of the first compressor 14 is connected to the inlet of the first heat exchanger 15, which in turn is connected to the inlet of multiple refrigerator expansion valves 26. The outlet of each refrigerator expansion valve 26 is connected to the inlet of a 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 connected in series to form a refrigerant circuit. The high-temperature, high-pressure gaseous refrigerant discharged from the first compressor 14 flows into the first heat exchanger 15, where it releases heat to the outside atmosphere. After the heat is released, the refrigerant is throttled and reduced in pressure by the refrigerator expansion valve 26, becoming a low-temperature, low-pressure liquid refrigerant that enters the refrigerator heat exchanger 223. The refrigerant absorbs the temperature of the air in the storage space of the items within the refrigerator heat exchanger 223, thereby achieving the refrigeration or freezing function of the vehicle refrigerator 22.

[0126] On the one hand, the above-mentioned refrigerator expansion valve 26 can control the on-off function of the refrigerant flow path where the refrigerator heat exchanger 223 is located, that is, it controls 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 multiple refrigerator heat exchangers 223 can operate at the same time or only partially operate. On the other hand, the refrigerator expansion valve 26 can also adjust the evaporation pressure and evaporation temperature of the refrigerant entering its corresponding refrigerator heat exchanger 223, so that the item storage space of multiple vehicle-mounted refrigerators 22 can have different storage temperatures.

[0127] To enhance the functionality of the vehicle refrigerator 22, as an embodiment, the vehicle refrigerator 22 may further include a heater 225 for heating the air within the storage space. While the refrigerator heat exchanger 223 acts as an evaporator to cool the storage space, if the user wishes to heat items stored there, the first compressor 14 and the refrigerator heat exchanger 223 may not be activated. Instead, the heater 225 heats the air within the storage space, thereby ensuring that the air within the storage space remains at a certain temperature for heating or keeping the items warm.

[0128] In addition, when the user has a cooling demand for one of the multiple vehicle refrigerators 22 and a heating demand for another vehicle refrigerator 22, the refrigerator heat exchanger 223 corresponding to one vehicle refrigerator 22 can be operated to cool the item storage space in the vehicle refrigerator 22, and the refrigerator heat exchanger 223 corresponding to the other vehicle refrigerator 22 can be turned off, and the heating element 225 corresponding to the other vehicle refrigerator 22 can be turned on, thereby achieving the effect of cooling one vehicle refrigerator 22 and heating the other vehicle refrigerator 22.

[0129] In addition, when the refrigerator heat exchanger 223 is used as a condenser in the heating item storage space, if the user wants to quickly increase the temperature of the item storage space, the refrigerator heat exchanger 223 and the heating element 225 can be turned on at the same time to increase the heating speed in the item storage space.

[0130] As another embodiment, the vehicle refrigerator 22 may further include a cooling element for cooling the air within the storage space. When the refrigerator heat exchanger 223 acts as a condenser to heat the storage space, if the user wishes to cool items stored in the storage space, the first compressor 14 and the refrigerator heat exchanger 223 may not be activated. Instead, the cooling element cools the air within the storage space, thereby refrigerating or freezing the items.

[0131] In addition, when the user has a cooling demand for one of the multiple car refrigerators 22 and a heating demand for another car refrigerator 22, the refrigerator heat exchanger 223 corresponding to one car refrigerator 22 can be operated to heat the item storage space in the car refrigerator 22, and the refrigerator heat exchanger 223 corresponding to the other car refrigerator 22 can be turned off, and the cooling element corresponding to the other car refrigerator 22 can be turned on, thereby achieving the effect of heating one car refrigerator 22 and cooling the other car refrigerator 22.

[0132] In addition, when the refrigerator heat exchanger 223 is used as an evaporator to cool the item storage space, if the user wants to quickly lower the temperature of the item storage space, the refrigerator heat exchanger 223 and the cooling element can be turned on at the same time to increase the cooling speed in the item storage space.

[0133] Optionally, refer to Figure 4 As shown, the inlet of the first air-conditioning refrigerant branch 51 is connected to the first compressor 14, and the outlet of the first air-conditioning refrigerant branch 51 is connected to the inlet of the second air-conditioning refrigerant branch 52 and the inlets of at least two refrigerator heat exchange paths 4. The outlet of the second air-conditioning refrigerant branch 52 and the outlets of at least two refrigerator heat exchange paths 4 are connected to the inlet of the first compressor 14. The vehicle thermal management system 100 also includes a pressure regulating structure 3, which is disposed on the second air-conditioning refrigerant branch 52 and near 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). Alternatively, the pressure regulating structure 3 is disposed on at least one of the parallel refrigerator heat exchange paths 4 and near the outlet of the refrigerator heat exchange path.

[0134] Among them, the pressure regulating structure 3 has a first conduction state. In the first conduction state, 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.

[0135] It should be noted that the pressure regulating structure 3 is provided on at least one of the refrigerator heat exchange flow paths 4 connected in parallel, which means that the pressure regulating structure 3 can be provided on multiple refrigerator heat exchange flow paths 4 connected in parallel, or the pressure regulating structure 3 is provided on any one of the multiple refrigerator heat exchange flow paths 4 connected in parallel, or the pressure regulating structure 3 is provided on at least two of the multiple refrigerator heat exchange flow paths 4 connected in parallel.

[0136] 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, 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. Since the second heat exchanger 12 is connected in parallel with the vehicle refrigerator 22, the outlet of the pressure regulating structure 3 is connected to 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.

[0137] Similarly, for the embodiment in which the pressure regulating structure 3 is arranged in at least one of the refrigerator heat exchange flow paths 4 connected in parallel with each other and is close to the outlet of the refrigerator heat exchange flow path 4, and the inlet of the pressure regulating structure 3 is connected to the outlet of the vehicle 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 vehicle refrigerator 22, and since the second heat exchanger 12 is connected in parallel with the vehicle refrigerator 22, the outlet of the pressure regulating structure 3 is in a connected state 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.

[0138] The refrigerant pressure (i.e., the evaporation pressure) within the second heat exchanger 12 is positively correlated with the refrigerant's evaporation temperature; that is, the lower the refrigerant pressure, the lower the evaporation temperature. By adjusting the refrigerant pressure at the inlet and outlet of the pressure regulating structure 3, the refrigerant pressure within the second heat exchanger 12 and the refrigerant pressure within the vehicle refrigerator 22 can be adjusted. This allows the refrigerant pressures within the second heat exchanger 12 and within the vehicle refrigerator 22 to differ, resulting in different evaporation temperatures for the refrigerant within the vehicle refrigerator 22 and the second heat exchanger 12. This allows the second heat exchanger 12 and the vehicle refrigerator 22 to have different cooling rates when the vehicle refrigerator 22 and the air conditioning system 1 are used simultaneously, depending on the target temperature. This allows the two to meet different user requirements for the passenger compartment temperature and the temperature within the vehicle refrigerator 22.

[0139] Alternatively, in the embodiment in which the inlet of the pressure regulating structure 3 is connected to the outlet of the second heat exchanger 12, in the first conductive state, the refrigerant pressure at the inlet of the pressure regulating structure 3 may be greater than the refrigerant pressure at the outlet of the pressure regulating structure 3, such that the refrigerant pressure within the second heat exchanger 12 is greater than the refrigerant pressure within the vehicle refrigerator 22. Since the refrigerant pressure within the second heat exchanger 12 is greater than the refrigerant pressure within the vehicle refrigerator 22 in the first conductive state, the evaporation temperature of the refrigerant within the second heat exchanger 12 is greater than the refrigerant evaporation temperature within the vehicle refrigerator 22. That is, when the air-conditioning system 1 is operating normally, the cooling temperature of the vehicle refrigerator 22 is lower than that of the air-conditioning system 1. This satisfies the lower cooling temperature requirement of the vehicle refrigerator 22 when the second heat exchanger 12 and the vehicle refrigerator 22 share the first compressor 14 and both the second heat exchanger 12 and the vehicle refrigerator 22 are cooling simultaneously, thereby improving the cooling capacity and cooling speed of the vehicle refrigerator 22.

[0140] In the above embodiment, the pressure regulating structure 3 can be a throttle valve. The throttle valve can be arranged on the air conditioning refrigerant flow path 5 and downstream of the second heat exchanger 12, so that in the first conduction state, the refrigerant pressure on the throttle valve inlet side can be greater than the refrigerant pressure on the throttle valve outlet side. The throttle valve can adjust the amount of refrigerant passing through the throttle valve by adjusting its opening, thereby causing the refrigerant pressure on the throttle valve inlet and outlet sides to differ. In other embodiments, the pressure regulating structure 3 can also be a pressure regulating valve, a flow regulating valve, etc.

[0141] Optionally, for the embodiment in which the inlet of the pressure regulating structure 3 is connected to the outlet of the vehicle 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 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 refrigerator 22, that is, when the air-conditioning system 1 is operating normally, the cooling temperature of the vehicle refrigerator 22 is lower than the cooling temperature of the air-conditioning system 1, thereby satisfying the situation in which the second heat exchanger 12 and the vehicle refrigerator 22 share the first compressor 14, and the second heat exchanger 12 and the vehicle refrigerator 22 are cooled at the same time, which can meet the lower cooling temperature requirement of the vehicle refrigerator 22 and improve the cooling capacity and cooling speed of the vehicle refrigerator 22.

[0142] For the above embodiment, the pressure regulating structure 3 can be a boosting valve, which can be arranged on the second refrigerator heat exchange branch 42 and located downstream of the vehicle refrigerator 22, so that in the first conduction state, the refrigerant pressure on the inlet side of the boosting valve can be lower than the refrigerant pressure on the outlet side of the boosting valve.

[0143] Optionally, the pressure regulating structure 3 further has a second conduction state. In the second conduction state, 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 pipeline. In this case, the refrigerant pressure in the parallel second heat exchanger 12 and the vehicle refrigerator 22 is the same, and the evaporation temperature of the refrigerant is also the same.

[0144] When the demand for the vehicle refrigerator 22 is high and the demand for the air conditioner is low, the pressure regulating structure 3 can be placed in the first conduction state to give priority to meeting the cooling demand of the vehicle refrigerator 22; when the demand for the vehicle refrigerator 22 is low and the demand for the air conditioner is high, the pressure regulating structure 3 can be placed in the second conduction state to give priority to meeting the cooling demand of the air conditioning system 1.

[0145] 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 refrigerant pressure difference is within this range, the cooling temperature of the vehicle refrigerator 22 can be reduced as much as possible while ensuring normal operation of the air conditioning system 1, thereby meeting the cooling needs of the vehicle refrigerator 22.

[0146] In order to improve the intelligence level of the vehicle thermal management system 100, optionally, as Figure 4 As shown, the air conditioning system 1 further includes a first temperature and pressure sensor 13, which is located downstream of the second heat exchanger 12. The vehicle thermal management system 100 further includes a second temperature and pressure sensor 25, which is located downstream of the vehicle 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.

[0147] 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 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 cooling temperature required by the user.

[0148] Optionally, the refrigerator expansion valve 26 in the above embodiment can be integrated on the vehicle refrigerator 22. The refrigerator expansion valve 26 can be installed on the outside of the vehicle refrigerator 22 and connected to the heat exchange structure inside the vehicle refrigerator 22 (such as the refrigerator heat exchanger 223) through a pipeline. It can also be installed inside the vehicle refrigerator 22, for example, at the inlet or outlet of the heat exchange structure inside the vehicle refrigerator 22. The present disclosure does not limit the specific setting position of the refrigerator expansion valve 26.

[0149] In order to improve the heat exchange effect between the refrigerator heat exchanger 223 and the air in the article storage space, optionally, as Figure 5 As shown, the refrigerator heat exchanger 223 includes a heat exchange tube 221 and a heat exchange shell 222. The inner surface of the heat exchange shell 222 defines an article storage space. The outlet of the first compressor 14 is connected to the inlet of the heat exchange tube 221, and the outlet of the heat exchange tube 221 is connected to the inlet of the first compressor 14. The heat exchange tube 221 is in thermal contact with the outer surface of the heat exchange shell 222, so that the refrigerant in the heat exchange tube 221 can directly exchange heat with the air in the article storage space through the heat exchange shell 222.

[0150] The inlet and outlet of the first compressor 14 are connected to the outlet and inlet of the heat exchange tube 221, thereby providing the heat exchange tube 221 with a refrigerant for heat exchange. The heat exchange tube 221 is in thermal contact with the outer surface of the heat exchange housing 222, while the inner surface of the heat exchange housing 222 defines an item storage space. The heat exchange housing 222 can directly contact the air within the item storage space, so that the cold or heat of the refrigerant in the heat exchange tube 221 can be directly transferred to the heat exchange housing 222 through the heat exchange tube 221. Direct heat exchange occurs with the air within the item storage space through the heat exchange housing 222, reducing the loss of cold or heat during the transfer process and improving the cooling or heating efficiency of the vehicle refrigerator 22.

[0151] Optionally, the thermal conductivity of the heat exchange housing 222 may be 201W / mk-237W / mk. Materials with this coefficient have good thermal conductivity and can meet the heat exchange requirements of the heat exchange tube 221 exchanging heat with the air in the article storage space through the heat exchange housing 222.

[0152] The present disclosure does not limit the specific material of the heat exchange shell 222. For example, the material of the heat exchange shell 222 can be aluminum or copper.

[0153] As mentioned above, the vehicle refrigerator 22 may include a heating element 225 such as Figure 5 As shown, in one embodiment provided by the present disclosure, the heating element 225 may include a heating film, which covers the outer surface of the heat exchange shell 222 and / or the side of the heat exchange tube 221 facing away from the heat exchange shell 222.

[0154] For the embodiment mentioned above in which the vehicle refrigerator 22 includes a cooling element, the cooling element may include a semiconductor refrigeration sheet covering the outer surface of the heat exchange shell 222 and / or the side of the heat exchange tube 221 facing away from the heat exchange shell 222 .

[0155] The heating film or semiconductor refrigeration sheet covering 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 item storage space through the heat exchange shell 222, thereby reducing heat loss during heating or cooling.

[0156] The heating film or semiconductor refrigeration sheet covering the side of the heat exchange tube 221 facing away from the heat exchange shell 222 can not only exchange heat with the air in the item storage space through the heat exchange tube 221 and the heat exchange shell 222, but also press the heat exchange tube 221 against the heat exchange shell 222 to ensure thermal contact between the heat exchange tube 221 and the heat exchange shell 222.

[0157] In order to further improve the heat exchange efficiency, optionally, as Figure 4 As shown, the vehicle refrigerator 22 also includes a fan 224, which is used to accelerate airflow in the storage space. For example, the fan 224 is used to generate airflow that can exchange heat with the refrigerant in the heat exchange tube 221 and enter the storage space. The fan 224 can increase the flow between the air near the heat exchange tube 221 and the air in the storage space, thereby improving the heat exchange efficiency between the heat exchange tube 221 and the air in the storage space, and increasing the heating or cooling speed of the vehicle refrigerator 22. It will be understood that when heating is performed by the heater 225 or cooling is performed by the cooling element, the fan 224 can increase the flow between the air near the heater 225 or cooling element and the air in the storage space, thereby improving the heat exchange efficiency between the heater 225 or cooling element and the air in the storage space, and increasing the heating or cooling speed of the vehicle refrigerator 22.

[0158] Optionally, a vent is formed in the heat exchange housing 222, and the fan 224 is disposed at the vent. Providing the vent on the heat exchange housing 222 to accommodate the fan 224 eliminates the need for the fan 224 to occupy the volume of the storage space. Furthermore, the vent allows the fan 224 to directly drive air flow between the two sides of the vent, creating convection and thereby improving the heat exchange efficiency of the heat exchange tube 221.

[0159] Alternatively, as Figure 4As shown, the air conditioning system 1 further includes a gas-liquid separator 17. The inlet of the gas-liquid separator 17 is connected to the outlets of the multiple refrigerator heat exchangers 223 and the outlet of the second heat exchanger 12. The outlet of the gas-liquid separator 17 is connected to the inlet of the first compressor 14. Before the refrigerant flowing out of the outlets of the refrigerator heat exchangers 223 and the second heat exchanger 12 returns to the first compressor 14, it passes through the gas-liquid separator 17 to separate the liquid from the gas in the refrigerant, thereby allowing the gas refrigerant to return to the first compressor 14 to prevent damage to the first compressor 14.

[0160] As a second aspect of the present disclosure, the present disclosure provides a vehicle including the above-mentioned vehicle thermal management system 100 .
