DETAILED DESCRIPTION

[0053] The specific embodiments of the present disclosure will be described below in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0054] In the present disclosure, unless otherwise specified, the orientation words such as "upstream, downstream" are generally defined based on the direction of refrigerant flow, and "inner, outer" refer to the inner and outer of the profile of the corresponding components. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0055] In the description of the present disclosure, it should also be noted that, unless otherwise explicitly specified and limited, the terms "setting", "connecting", "connecting", "installing" 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.

[0056] As a first aspect of the present disclosure, as shown in Figures 1 to 5 The present disclosure provides a vehicle thermal management system 100, comprising a plurality of vehicle refrigerators 22, each of which has an article storage space. Wherein the vehicle thermal management system 100 has a first working mode, in which one of the plurality of vehicle refrigerators 22 can heat its article storage space, and another of the plurality of vehicle refrigerators 22 can cool its article storage space.

[0057] Through 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 storage at a certain temperature. In addition, the plurality of vehicle refrigerators 22 can be installed at different positions in the passenger compartment of the vehicle to facilitate users at different positions in the passenger compartment to take articles in the vehicle refrigerators 22. Furthermore, 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 to 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 to refrigerate or freeze the articles in the article storage space, so that each article storage space can have a different storage temperature to meet the needs of users for different storage temperatures of different foods.

[0058] The above vehicle refrigerator 22 can heat or cool its article storage space by flowing through the refrigerant of the vehicle refrigerator 22, or by the heating element 225 or the cooling element, or one of the plurality of vehicle refrigerators 22 can heat or cool its article storage space by flowing through the refrigerant of the vehicle refrigerator 22, and another of the plurality of vehicle refrigerators 22 can cool or heat its article storage space by the cooling element or the heating element 225, which is not limited by the present disclosure.

[0059] For example, in one embodiment provided by the present disclosure, one of the plurality of vehicle refrigerators 22 has a heating element 225 for heating the article storage space of the vehicle refrigerator 22, and another of the plurality of vehicle refrigerators 22 has a cooling element for cooling the article storage space of the vehicle refrigerator 22. In the first working mode, the heating element 225 on one of the plurality of vehicle refrigerators 22 can heat the article storage space of 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.

[0060] In other embodiments provided by the present disclosure, the first working mode can also be achieved by exchanging heat between the refrigerant and the article storage space of the vehicle refrigerator 22. For example, in one embodiment provided by the present disclosure, Figure 1 As shown, the plurality of vehicle refrigerators 22 include a first vehicle refrigerator 226 and a second vehicle refrigerator 227. The vehicle thermal management system 100 includes a compressor 14. The compressor 14, the first vehicle refrigerator 226, and the second vehicle refrigerator 227 can be connected in series to form a circuit. In a first operating mode, the refrigerant flowing through the first vehicle refrigerator 226 can heat the storage space of the first vehicle refrigerator 226, and the refrigerant flowing through the second vehicle refrigerator 227 can cool the storage space of the second vehicle refrigerator 227.

[0061] The refrigerant discharged from the compressor 14 can flow into the first vehicle-mounted refrigerator 226 and release heat to the item storage space of the first vehicle-mounted refrigerator 226 to increase the temperature of the item storage space of the first vehicle-mounted refrigerator 226, thereby achieving heating or insulation of the items. The refrigerant after releasing heat in the first vehicle-mounted refrigerator 226 enters the second vehicle-mounted refrigerator 227 and absorbs 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, thereby achieving refrigeration or freezing of the items.

[0062] The first vehicle refrigerator 226 and the second vehicle refrigerator 227 are both connected to the same 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.

[0063] Optionally, the compressor 14 may be the compressor 14 of the air-conditioning system 1 . In this way, multiple vehicle refrigerators 22 and the air-conditioning system 1 share the compressor 14 , further reducing the increased cost of installing multiple vehicle refrigerators 22 and the space occupied in the vehicle.

[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 221, or a heat exchanger (such as the refrigerator heat exchanger 223 described 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] 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.

[0066] 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.

[0067] 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.

[0068] 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, and the present disclosure does not limit this.

[0069] For example, in one embodiment provided by the present disclosure, as shown in FIG. 1, the vehicle thermal management system 100 can include 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 selectively conductive or cut-off 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 have heating elements 225 for heating the article storage spaces. In a first working mode, the 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. Figure 2 Figure 4 Since the outlet of the compressor 14 is selectively conductive or cut-off 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 conductive to one of the vehicle refrigerators 22 connected in parallel with each other, and not conductive to 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 conduction or cut-off 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, and the present disclosure does not limit the same.

[0070] 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 effect of increasing the storage space of the vehicle and meeting the needs of users for different storage temperatures of different foods can be achieved as much as possible without increasing the cost of the vehicle and occupying too much volume of the vehicle. Alternatively, 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.

[0071] 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 effect of increasing the storage space of the vehicle and meeting the needs of users for different storage temperatures of different foods can be achieved as much as possible without increasing the cost of the vehicle and occupying too much volume of the vehicle. Alternatively, 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.

[0072] ​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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] Optionally, the vehicle thermal management system 100 can further have a fourth working mode, in which the heating elements 225 on at least two of the plurality of vehicle refrigerators 22 can heat the article storage spaces of the at least two vehicle refrigerators 22. When a user has a heating demand for at least two of the plurality of vehicle refrigerators 22, the vehicle thermal management system 100 can be brought into 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 spaces by means of the heating elements 225.

[0077] In the fourth working mode described above, the heating elements 225 on at least two of the plurality of vehicle refrigerators 22 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 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 warm the articles, 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.

[0078] Optionally, as shown in Figure 2 and Figure 4 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 depressurized 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 spaces in the vehicle refrigerators 22 to realize the refrigeration or freezing function of the vehicle refrigerators 22.

[0079] The above refrigerator expansion valve 26 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. 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 plurality of vehicle refrigerators 22 can have different preservation temperatures.

[0080] Optionally, the above 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.

[0081] It can be understood that, for the case that the vehicle refrigerator 22 includes a refrigerator heat exchanger 223, at least two refrigerator expansion valves 26 correspond to the refrigerator heat exchangers 223 of the at least two vehicle refrigerators 22 one by one, the outlet of the compressor 14 is connected with the inlet of the first heat exchanger 15, the outlet of the first heat exchanger 15 is connected with the inlet of the refrigerator expansion valve 26, and the outlet of the refrigerator expansion valve 26 is connected with 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 connected in series to form a refrigerant circuit.

[0082] Optionally, as shown in Figure 4 The vehicle thermal management system 100 further includes a second heat exchanger 12, the second heat exchanger 12 is connected in parallel with the at least two vehicle refrigerators 22, the outlet of the first heat exchanger 15 is further connected with the inlet of the second heat exchanger 12, and the outlet of the first heat exchanger 15 can be selectively connected or cut off with the inlet of the second heat exchanger 12, and the outlet of the second heat exchanger 12 is connected with 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 connected in series to form a circuit.

[0083] Since the outlet of the first heat exchanger 15 can be selectively connected or cut off with the inlet of the second heat exchanger 12, and the outlet of the first heat exchanger 15 is connected with 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 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.

[0084] Alternatively, the second heat exchanger 12 may be an evaporator in the air conditioning system 1, which absorbs heat from the passenger compartment to cool it. Since the second heat exchanger 12 is connected in parallel with at least two onboard refrigerators 22, the onboard refrigerators 22 and the air conditioning system 1 can operate simultaneously, meeting the user's need for simultaneous cooling of the passenger compartment and the onboard refrigerators 22. The second heat exchanger 12 may also be a heat exchanger in a battery thermal management system, used to cool the battery pack. The second heat exchanger 12 may also be provided in an electric drive system, allowing the refrigerant to provide cooling to the coolant in the electric drive system through the second heat exchanger 12, thereby cooling equipment requiring cooling, such as the battery pack, motor, and motor controller.

[0085] Alternatively, as Figure 4 As shown, in an embodiment where the second heat exchanger 12 is an evaporator in the air conditioning system 1, the air conditioning system 1 may include an air conditioning expansion valve 16, through which the outlet of the compressor 14 is connected to the inlet of the second heat exchanger 12. The air conditioning expansion valve 16 can be used to control the selective connection or disconnection between the outlet of the first heat exchanger 15 and the inlet of the second heat exchanger 12. It can also adjust the evaporation pressure and evaporation temperature of the refrigerant entering the second heat exchanger 12, thereby adjusting the cooling temperature of the passenger compartment.

[0086] Alternatively, as Figure 4 As shown, the air conditioning system 1 may further include a gas-liquid separator 17. The inlet of the gas-liquid separator 17 is connected to the outlets of at least two vehicle refrigerators 22 and the outlet of the second heat exchanger 12. The outlet of the gas-liquid separator 17 is also connected to the inlet of the compressor 14. Before the refrigerant flowing out of the outlets of the vehicle refrigerator 22 and the second heat exchanger 12 returns to the compressor 14, it passes through the gas-liquid separator 17 to separate the liquid from the gas in the refrigerant, thereby allowing the gaseous refrigerant to return to the compressor 14 to prevent damage to the compressor 14.

[0087] Optionally, refer to Figure 4 As shown, the vehicle thermal management system 100 may further include a pressure regulating structure 3, which is disposed downstream of the second heat exchanger 12, or downstream of at least one of the vehicle refrigerators 22 connected in parallel.

[0088] 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.

[0089] It should be noted that the pressure regulating structure 3 is arranged downstream of at least one of the vehicle-mounted refrigerators 22 in parallel with each other means that the pressure regulating structure 3 can be arranged downstream of each of the vehicle-mounted refrigerators 22 in parallel with each other, or the pressure regulating structure 3 can be arranged downstream of any one of the vehicle-mounted refrigerators 22 in parallel with each other, or the pressure regulating structure 3 can be arranged downstream of at least two of the vehicle-mounted refrigerators 22 in parallel with each other.

[0090] 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-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.

[0091] Similarly, for the embodiment in which the inlet of the pressure regulating structure 3 is connected with the outlet of the vehicle-mounted refrigerator 22 (i.e. the pressure regulating structure 3 is arranged downstream of the vehicle-mounted 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-mounted refrigerator 22, 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 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.

[0092] 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 vehicle-mounted refrigerator 22 can be adjusted, so that the refrigerant pressures in the second heat exchanger 12 and the vehicle-mounted refrigerator 22 are different, thereby making the evaporation temperatures of the refrigerants in the second heat exchanger 12 and the vehicle-mounted refrigerator 22 different, so that the second heat exchanger 12 and the vehicle-mounted 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-mounted refrigerator 22 when the vehicle-mounted refrigerator 22 and the air conditioning system 1 are used at the same time.

[0093] 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.

[0094] For the above 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.

[0095] 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.

[0096] For the above 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.

[0097] 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 sides 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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. 2, the vehicle thermal management system 100 includes a compressor 14, at least two vehicle refrigerators 22 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 selectively conductive or cut-off 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 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. Figure 3

[0103] Since the outlet of the compressor 14 is selectively conductive or cut-off to 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 thus, in the first working mode described above, the compressor 14 can be conductive to one of the at least two vehicle refrigerators 22 and cut-off to 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 selective conduction or cut-off of the outlet of the compressor 14 to the refrigerant inlets of the at least two vehicle refrigerators 22 can be realized by a switching valve or a switch valve, which is not limited in the present disclosure.

[0104] 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 of different foods can be met as much as possible without increasing the cost and 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.

[0105] ​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.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] Optionally, as shown in Figure 3 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 decompressed 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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. 6, 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. Figure 2

[0118] ​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 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 is directly performed between the heat exchange shell 222 and the air in the article containing space, reducing the loss of cold or heat in the conduction process, and improving the refrigeration or heating efficiency of the vehicle-mounted refrigerator 22.

[0119] Optionally, the heat conduction coefficient of the heat exchange shell 222 can be 201 W / mk-237 W / mk. The material with the coefficient has good heat conduction performance, and can meet the heat exchange requirement of the heat exchange pipe 221 for heat exchange with the air in the article containing space through the heat exchange shell 222.

[0120] 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.

[0121] As mentioned above, the vehicle-mounted refrigerator 22 can include a heating element 225, such as Figure 5 As shown 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.

[0122] For the above-mentioned embodiment in which the vehicle-mounted refrigerator 22 includes 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.

[0123] 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.

[0124] 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.

[0125] To further improve the heat exchange efficiency, optionally, as Figure 4As shown, the vehicle-mounted refrigerator 22 further comprises a fan 224, which is configured to accelerate the airflow in the article storage 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 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 refrigeration speed of the vehicle-mounted 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 refrigeration speed of the vehicle-mounted refrigerator 22.

[0126] 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.

[0127] As a second aspect of the present disclosure, the present disclosure provides a vehicle comprising the vehicle thermal management system 100 described above.
