[0023] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The following is for reference. Figures 1-4 An integrated refrigeration system for vehicle-mounted multi-units according to an embodiment of the present invention is described. The integrated refrigeration system can be applied to vehicle-mounted multi-unit 1, enabling vehicle-mounted multi-unit 1 to achieve a cooling effect. Vehicle-mounted multi-unit 1 can be installed in a vehicle.

[0025] An integrated refrigeration system with multiple onboard units according to a first aspect embodiment of the present invention, such as Figures 1-4As shown, the vehicle-mounted multi-unit 1 includes at least a vehicle-mounted refrigerator / heater 200 and a vehicle-mounted beverage dispenser 100. The integrated refrigeration system may include: a compressor 11, a condenser 12, a first refrigeration unit 13, a second refrigeration unit 14, and a refrigerant distribution unit 20. The compressor 11 is configured to compress the refrigerant within the integrated refrigeration system, thereby increasing the temperature and pressure of the refrigerant and allowing it to circulate within the integrated refrigeration system. The compressor discharge port 112 of the compressor 11 is connected to the condenser inlet 121 of the condenser 12. The first refrigeration unit 13 acts on the vehicle-mounted refrigerator / heater 200 and is configured to refrigerate the vehicle-mounted refrigerator / heater 200 to achieve refrigeration or freezing functions. The second refrigeration unit 14 acts on the vehicle-mounted refrigerator / heater 200... A beverage machine 100 is configured to cool the beverage machine 100 to extract cold drinks. The refrigerant input terminal 21 of the refrigerant distribution unit 20 is connected to the condenser outlet 122 of the condenser 12. The refrigerant distribution unit 20 is selectively connected to at least one of the first refrigeration unit 13 and the second refrigeration unit 14 so that the refrigerant flowing out of the condenser 12 flows into at least one of the first refrigeration unit 13 and the second refrigeration unit 14. The refrigerant distribution unit 20 is configured to control the on / off connection between the condenser 12 and the first refrigeration unit 13 and the second refrigeration unit 14. The refrigerant distribution unit 20 is also configured to distribute the refrigerant flow into the first refrigeration unit 13 and the second refrigeration unit 14.

[0026] It should be noted that vehicle-mounted multi-unit systems can include vehicle-mounted refrigerators and beverage dispensers. Currently, vehicle-mounted refrigerators and beverage dispensers in vehicles are generally independent products, with each having its own independent refrigeration system. This increases the overall energy consumption of the vehicle and results in cost waste. In addition, vehicle-mounted refrigerators and beverage dispensers, which each have their own refrigeration system, are relatively large and occupy a lot of interior space.

[0027] Based on this, this application proposes an integrated refrigeration system with multiple vehicle-mounted units. The multiple vehicle-mounted units 1 can include various vehicle-mounted devices, such as a vehicle-mounted refrigerator / warmer 200 and a vehicle-mounted beverage dispenser 100. The multiple vehicle-mounted units 1 can include at least the vehicle-mounted refrigerator / warmer 200 and the vehicle-mounted beverage dispenser 100. This application example uses the vehicle-mounted units 1 including the vehicle-mounted refrigerator / warmer 200 and the vehicle-mounted beverage dispenser 100. Users can use the vehicle-mounted refrigerator / warmer 200 to store food, and users can drink beverages from the vehicle-mounted beverage dispenser 100, such as drinking water and juice. The integrated refrigeration system can include a compressor 11, a condenser 12, a first refrigeration unit 13, a second refrigeration unit 14, and a refrigerant distribution unit 20. Refrigerant flows within the integrated refrigeration system. The compressor 11 can compress the refrigerant within the integrated refrigeration system. The compressor 11 can heat and pressurize the gaseous refrigerant into a high-temperature, high-pressure refrigerant gas, and promote the circulation of the refrigerant within the integrated refrigeration system. The compressor 11 has a compressor discharge port 112, which is connected to the condenser inlet 121 of the condenser 12. The gaseous refrigerant in the compressor 11 can flow into the condenser 12 through the compressor discharge port 112 and the condenser inlet 121. The gaseous refrigerant releases heat and liquefies into liquid refrigerant in the condenser 12. The refrigerant flowing out of the condenser 12 is a high-pressure room temperature liquid.

[0028] The first refrigeration unit 13 can act on the vehicle-mounted refrigerator / warmer 200, providing refrigeration or freezing functions to the refrigerator / warmer 200, thus extending the food's storage time. The second refrigeration unit 14 can act on the vehicle-mounted beverage dispenser 100, providing refrigeration to extract cold drinks, allowing the dispenser to provide cold beverages for users to enjoy in their vehicles. The liquid refrigerant flowing out of the condenser 12 can flow to the first refrigeration unit 13 and the second refrigeration unit 14 respectively. The first refrigeration unit 13 acts on the vehicle-mounted refrigerator / heater 200, and the second refrigeration unit 14 acts on the vehicle-mounted beverage machine 100. That is, the integrated refrigeration system can simultaneously provide refrigerant to the vehicle-mounted refrigerator / heater 200 and the vehicle-mounted beverage machine 100. This is beneficial for the vehicle-mounted refrigerator / heater 200 and the vehicle-mounted beverage machine 100 to share the integrated refrigeration system, which helps to reduce vehicle energy consumption, reduce costs, and also reduces the volume of the vehicle-mounted refrigerator / heater 200 and the vehicle-mounted beverage machine 100. This helps to reduce the space occupied by the vehicle-mounted multi-unit 1 and improve the space utilization rate of the vehicle.

[0029] The refrigerant inlet 21 of the refrigerant distribution unit 20 is connected to the condenser outlet 122 of the condenser 12, meaning that liquid refrigerant in the condenser 12 can flow into the refrigerant distribution unit 20 through the condenser outlet 122 and the refrigerant inlet 21. The refrigerant distribution unit 20 is connected between the first refrigeration unit 13 and the condenser 12, and also between the second refrigeration unit 14 and the condenser 12. The refrigerant distribution unit 20 can selectively connect to at least one of the first refrigeration unit 13 and the second refrigeration unit 14, so that refrigerant flowing out of the condenser 12 can flow into at least one of the first refrigeration unit 13 and the second refrigeration unit 14. When the refrigerant distribution unit 20 is connected to the first refrigeration unit 13, refrigerant flowing out of the condenser 12 can flow into the first refrigeration unit 13 through the refrigerant distribution unit 20; when the refrigerant distribution unit 20 is connected to the second refrigeration unit 14, refrigerant flowing out of the condenser 12 can flow into the second refrigeration unit 14 through the refrigerant distribution unit 20. The refrigerant distribution unit 20 is configured to control the connection and disconnection between the condenser 12 and the first refrigeration unit 13 and the second refrigeration unit 14. When the refrigerant distribution unit 20 is connected to the first refrigeration unit 13, the condenser 12 is connected to the first refrigeration unit 13; when the refrigerant distribution unit 20 is not connected to the first refrigeration unit 13, the condenser 12 is not connected to the first refrigeration unit 13, thereby achieving the effect of the refrigerant distribution unit 20 controlling the connection and disconnection between the condenser 12 and the first refrigeration unit 13. Similarly, when the refrigerant distribution unit 20 is connected to the second refrigeration unit 14, the condenser 12 is connected to the second refrigeration unit 14; when the refrigerant distribution unit 20 is not connected to the second refrigeration unit 14, the condenser 12 is not connected to the second refrigeration unit 14, thereby achieving the effect of the refrigerant distribution unit 20 controlling the connection and disconnection between the condenser 12 and the second refrigeration unit 14.

[0030] The refrigerant distribution unit 20 can also distribute the refrigerant flow into the first refrigeration unit 13 and the second refrigeration unit 14. When the refrigerant distribution unit 20 is connected to both the first refrigeration unit 13 and the second refrigeration unit 14, the refrigerant flow into the first refrigeration unit 13 and the second refrigeration unit 14 can be adjusted according to the different refrigeration requirements of the vehicle-mounted refrigerator / heater 200 and the vehicle-mounted beverage machine 100. This helps to meet the different refrigerant flow requirements of the first refrigeration unit 13 and the second refrigeration unit 14, effectively controlling the refrigeration capacity of the vehicle-mounted refrigerator / heater 200 and the vehicle-mounted beverage machine 100, reducing the energy consumption of the integrated refrigeration system, and improving the reliability of the first refrigeration unit 13 and the second refrigeration unit 14. As an example, the refrigerant distribution unit 20 can also control the refrigerant flow into either the first refrigeration unit 13 or the second refrigeration unit 14 to zero, thereby achieving the effect of not connecting the refrigerant distribution unit 20 to either the first refrigeration unit 13 or the second refrigeration unit 14.

[0031] In this embodiment, by setting the first refrigeration unit 13 and the second refrigeration unit 14 of the integrated refrigeration system to act on the vehicle-mounted refrigerator / heater 200 and the vehicle-mounted beverage machine 100 respectively, it is beneficial to achieve the effect of the vehicle-mounted refrigerator / heater 200 and the vehicle-mounted beverage machine 100 sharing the integrated refrigeration system. It can also reduce the volume of the vehicle-mounted refrigerator / heater 200 and the vehicle-mounted beverage machine 100, which is beneficial to reduce the space occupation of the vehicle-mounted multi-unit 1 and improve the space utilization of the vehicle. In addition, the integrated refrigeration system is equipped with a refrigerant distribution unit 20, which is beneficial to control the refrigeration capacity of the vehicle-mounted refrigerator / heater 200 and the vehicle-mounted beverage machine 100, which is beneficial to reduce the energy consumption of the integrated refrigeration system, reduce the energy consumption of the vehicle, and reduce costs.

[0032] In some embodiments of the present invention, such as Figure 1 As shown, the refrigerant distribution unit 20 has a first refrigerant output terminal 22 and a second refrigerant output terminal 23. The first refrigerant output terminal 22 is connected to the first refrigeration unit 13, and the second refrigerant output terminal 23 is connected to the second refrigeration unit 14. The opening degree of both the first refrigerant output terminal 22 and the second refrigerant output terminal 23 can be adjusted.

[0033] The refrigerant distribution unit 20 may have a first refrigerant output terminal 22 and a second refrigerant output terminal 23. The refrigerant in the refrigerant distribution unit 20 can flow out of the refrigerant distribution unit 20 through the first refrigerant output terminal 22 and the second refrigerant output terminal 23. The first refrigerant output terminal 22 can be connected to the first refrigeration unit 13. The refrigerant in the refrigerant distribution unit 20 can flow into the first refrigeration unit 13 through the first refrigerant output terminal 22. The second refrigerant output terminal 23 can be connected to the second refrigeration unit 14. The refrigerant in the refrigerant distribution unit 20 can flow into the second refrigeration unit 14 through the second refrigerant output terminal 23. The opening degree of both the first refrigerant output terminal 22 and the second refrigerant output terminal 23 can be adjusted, that is, the refrigerant flow rate flowing out through the first refrigerant output terminal 22 and the second refrigerant output terminal 23 can be adjusted. This further realizes the effect of adjustable refrigerant flow rate into the first refrigeration unit 13 and the second refrigeration unit 14, which is conducive to further meeting the different refrigerant flow requirements of the first refrigeration unit 13 and the second refrigeration unit 14, which is conducive to further realizing the effect of controlling the refrigeration capacity of the vehicle-mounted refrigeration and heating box 200 and the vehicle-mounted beverage machine 100, which is conducive to further reducing the energy consumption of the integrated refrigeration system, and which is conducive to improving the reliability of the first refrigeration unit 13 and the second refrigeration unit 14.

[0034] As an example, the first refrigerant output terminal 22 can be equipped with a first one-way valve, which can prevent liquid backflow. By setting the first one-way valve, the liquid refrigerant flowing out of the first refrigerant output terminal 22 can flow into the first refrigeration unit 13, and the liquid refrigerant flowing into the first refrigeration unit 13 will not flow back to the first refrigerant output terminal 22. This helps to achieve the effect of unidirectional and stable flow of liquid refrigerant from the first refrigerant output terminal 22 to the first refrigeration unit 13, which helps to improve the reliability of refrigerant supply to the first refrigeration unit 13 and improves the reliability of the integrated refrigeration system.

[0035] The second refrigerant output terminal 23 may be equipped with a second one-way valve, which can prevent the backflow of liquid refrigerant. By setting the second one-way valve, the liquid refrigerant flowing out of the second refrigerant output terminal 23 can flow into the second refrigeration unit 14, and the liquid refrigerant flowing into the second refrigeration unit 14 will not flow back to the second refrigerant output terminal 23. This helps to achieve the effect of unidirectional and stable flow of liquid refrigerant from the second refrigerant output terminal 23 to the second refrigeration unit 14, which helps to improve the reliability of refrigerant supply to the second refrigeration unit 14, and further improves the reliability of the integrated refrigeration system.

[0036] In some embodiments of the present invention, such as Figure 1 As shown, the first refrigeration unit 13 has a first refrigeration output terminal 131, which is connected to the compressor inlet 111 of the compressor 11 so that the refrigerant flowing out of the first refrigeration unit 13 flows back to the compressor 11.

[0037] The first refrigeration unit 13 may have a first refrigeration output terminal 131. The liquid refrigerant flowing out of the condenser 12 can evaporate and absorb heat in the first refrigeration unit 13 to achieve a refrigeration effect, that is, the liquid refrigerant vaporizes into gaseous refrigerant. The first refrigeration output terminal 131 may be connected to the compressor inlet 111 of the compressor 11. The gaseous refrigerant flowing out of the first refrigeration unit 13 can flow into the compressor 11 through the first refrigeration output terminal 131 and the compressor inlet 111, which is beneficial to allow the refrigerant flowing out of the first refrigeration unit 13 to flow back to the compressor 11, and is beneficial to further realize the effect of refrigerant circulation in the integrated refrigeration system.

[0038] As an example, the first refrigeration unit 13 may include an evaporator 132 and a first capillary tube 133. The first capillary tube 133 may be connected between the evaporator 132 and the refrigerant distribution unit 20. The refrigerant flowing out of the condenser 12 can flow into the first capillary tube 133 through the refrigerant distribution unit 20. When the high-pressure, room-temperature liquid refrigerant flows through the first capillary tube 133, it is throttled and depressurized, thereby forming a low-temperature, low-pressure liquid refrigerant. The boiling point of the refrigerant decreases significantly as the pressure decreases. After the liquid refrigerant flowing out of the first capillary tube 133 enters the evaporator 132, it will quickly vaporize from liquid to gas. At the same time, the refrigerant can absorb a large amount of heat from the vehicle-mounted refrigerator / heater 200 during the evaporation process, thereby achieving the cooling effect of the first refrigeration unit 13 on the vehicle-mounted refrigerator / heater 200, so that the vehicle-mounted refrigerator / heater 200 can realize the refrigeration or freezing function. The evaporator 132 can be connected to the compressor inlet 111 of the compressor 11. The gaseous refrigerant flowing out of the evaporator 132 can flow back to the compressor 11, which is beneficial to further realize the effect of refrigerant circulation in the integrated refrigeration system.

[0039] In some embodiments of the present invention, such as Figures 1-3 As shown, the second refrigeration unit 14 may include a heat exchange structure 141, on which a refrigerant flow channel 1421 and a beverage flow channel are formed. The refrigerant flow channel 1421 is connected to the refrigerant distribution unit 20 and the compressor inlet 111 of the compressor 11. The beverage flow channel is connected to the liquid storage section 110 and the liquid outlet section 120 of the vehicle beverage machine 100. When refrigerant flows in the refrigerant flow channel 1421, the refrigerant and the beverage in the beverage flow channel exchange heat through the heat exchange structure 141.

[0040] The heat exchange structure 141 can have a refrigerant flow channel 1421 and a beverage flow channel. Refrigerant flows in the refrigerant flow channel 1421, and beverage flows in the beverage flow channel. The refrigerant flow channel 1421 can connect the refrigerant distribution unit 20 and the compressor inlet 111 of the compressor 11. Liquid refrigerant flowing out of the refrigerant distribution unit 20 can flow into the refrigerant flow channel 1421. The refrigerant in the refrigerant flow channel 1421 can evaporate and absorb heat in the second refrigeration unit 14, transforming into gaseous refrigerant. The gaseous refrigerant can flow out of the second refrigeration unit 14 and flow into the compressor 11 through the compressor inlet 111. This facilitates the return of the refrigerant flowing out of the second refrigeration unit 14 to the compressor 11, and further facilitates the circulation of refrigerant within the integrated refrigeration system. The beverage flow channel connects the liquid storage section 110 and the liquid dispensing section 120 of the vehicle-mounted beverage machine 100. Beverages can flow from the liquid storage section 110 into the beverage flow channel, and the beverages in the beverage flow channel can flow to the liquid dispensing section 120 of the vehicle-mounted beverage machine 100. Users can drink the beverages through the liquid storage section 110. When refrigerant flows in the refrigerant flow channel 1421, the refrigerant can exchange heat with the beverages in the beverage flow channel through the heat exchange structure 141. The liquid refrigerant can vaporize into gaseous refrigerant and absorb the heat of the beverages in the beverage flow channel, thereby lowering the temperature of the beverages in the beverage flow channel. This achieves the effect of the second refrigeration unit 14 cooling the vehicle-mounted beverage machine 100 to extract cold drinks.

[0041] As an example, the vehicle-mounted beverage machine 100 may also be equipped with a liquid drive pump 140, which can drive the beverage flowing out of the liquid storage section 110 to the second refrigeration unit 14, thereby improving the flow rate of the beverage.

[0042] In some embodiments of the present invention, such as Figures 1-3 As shown, the second refrigeration unit 14 may further include: a refrigerant flow section 142 and a beverage flow section 143. The refrigerant flow section 142 defines a refrigerant flow channel 1421, and the beverage flow section 143 defines a beverage flow channel. Both the refrigerant flow section 142 and the beverage flow section 143 are fixed to the heat exchange structure 141 and are heat exchanged with the heat exchange structure 141.

[0043] The refrigerant flow section 142 defines a refrigerant flow channel 1421, within which refrigerant can flow. The beverage flow section 143 defines a beverage flow channel, within which beverage can flow. Both the refrigerant flow section 142 and the beverage flow section 143 can be fixedly mounted on the heat exchange structure 141, and can be fixedly connected to the heat exchange structure 141 by welding, bonding, or other methods. Both the refrigerant flow section 142 and the beverage flow section 143 can cooperate with the heat exchange structure 141 for heat exchange. The refrigerant in the refrigerant flow section 142 evaporates and absorbs heat, which is then transferred to the heat exchange structure 141, lowering its temperature. The heat exchange structure 141 can then evenly transfer the cold energy to the beverage flow section 143, where the beverage absorbs the cold energy and cools down. This achieves the effect of heat exchange cooperation between the refrigerant flow section 142 and the beverage flow section 143 through the heat exchange structure 141, further enhancing the heat exchange cooperation between the refrigerant in the refrigerant channel 1421 and the beverage in the beverage channel. Furthermore, the refrigerant flow section 142 and the beverage flow section 143 are independent of each other; the refrigerant channel 1421 and the beverage channel are not connected, and the refrigerant in the refrigerant flow section 142 and the beverage in the beverage flow section 143 will not mix, improving the reliability of heat exchange between the refrigerant in the refrigerant channel 1421 and the beverage in the beverage channel.

[0044] As an example, the heat exchange structure 141 can be a metal plate, such as an aluminum plate or a copper plate. Metal plates have good thermal conductivity, which is beneficial to improving the heat exchange efficiency between the refrigerant and the beverage in the beverage flow channel.

[0045] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the refrigerant flow section 142 and the beverage flow section 143 are located on opposite sides of the heat exchange structure 141.

[0046] The refrigerant flow section 142 and the beverage flow section 143 can be located on opposite sides of the heat exchange structure 141. This embodiment of the application uses the example of the refrigerant flow section 142 and the beverage flow section 143 being located on opposite sides of the heat exchange structure 141 along its thickness direction. Along the thickness direction of the heat exchange structure 141, the refrigerant flow section 142 and the beverage flow section 143 are located on opposite sides of the heat exchange structure 141. The refrigerant in the refrigerant flow section 142 and the beverage in the beverage flow section 143 can flow on opposite sides of the heat exchange structure 141. Heat can be directly transferred through the heat exchange structure 141, which helps to shorten the heat transfer path, reduce the thermal resistance during heat exchange between the refrigerant and the beverage in the flow channels, and further improve the working efficiency during heat exchange between the refrigerant and the beverage in the flow channels.

[0047] In some embodiments of the present invention, a first accommodating space and a second accommodating space are formed on opposite sides of the heat exchange structure 141, at least a portion of the refrigerant flow section 142 is located in the first accommodating space, and at least a portion of the beverage flow section 143 is located in the second accommodating space.

[0048] A first accommodating space and a second accommodating space can be formed on opposite sides of the heat exchange structure 141, and the first accommodating space and the second accommodating space can be arranged opposite each other along the thickness direction of the heat exchange structure 141. At least a portion of the refrigerant flow section 142 can be located in the first accommodating space, which is beneficial to improving the reliability of the refrigerant flow section 142 when it is fixed to the heat exchange structure 141. At least a portion of the beverage flow section 143 can be located in the second accommodating space, which is beneficial to improving the reliability of the beverage flow section 143 when it is fixed to the heat exchange structure 141, and is beneficial to further realizing the effect of direct heat transfer through the heat exchange structure 141.

[0049] In some embodiments of the present invention, the refrigerant channel 1421 includes a plurality of sub-refrigerant channels, which are sequentially connected along the extension direction of the refrigerant channel 1421, and any two adjacent sub-refrigerant channels are bent and connected; and / or the beverage channel includes a plurality of sub-beverage channels, which are sequentially connected along the extension direction of the beverage channel, and any two adjacent sub-beverage channels are bent and connected.

[0050] The refrigerant channel 1421 may include multiple sub-refrigerant channels, which are sequentially connected along the extension direction of the refrigerant channel 1421. Alternatively, the beverage channel may include multiple sub-beverage channels, which are sequentially connected along the extension direction of the beverage channel. In this embodiment, the refrigerant channel 1421 may include multiple sub-refrigerant channels, which are sequentially connected along the extension direction of the refrigerant channel 1421. The beverage channel may include multiple sub-beverage channels, which are sequentially connected along the extension direction of the beverage channel. This embodiment is described using the example of the refrigerant channel 1421 including multiple sub-refrigerant channels, which are sequentially connected along the extension direction of the refrigerant channel 1421, and the beverage channel including multiple sub-beverage channels, which are sequentially connected along the extension direction of the beverage channel.

[0051] The refrigerant flow channel 1421 may include multiple sub-refrigerant flow channels, which can be connected sequentially along the extension direction of the refrigerant flow channel 1421. The multiple sub-refrigerant flow channels are connected sequentially, and any two adjacent sub-refrigerant flow channels are connected by bends. That is, any two adjacent sub-refrigerant flow channels are connected by bends. The multiple sub-refrigerant flow channels together form a continuous and bendable refrigerant flow channel 1421. This is beneficial to increasing the number of sub-refrigerant flow channels per unit area of ​​the refrigerant flow section 142, extending the length of the refrigerant flow channel 1421, increasing the heat exchange area of ​​the refrigerant flow section 142 and the heat exchange structure 141, improving the efficiency of the heat exchange coordination between the refrigerant in the refrigerant flow section 142 and the heat exchange structure 141, and improving the refrigeration efficiency of the second refrigeration unit 14.

[0052] As an example, multiple sub-refrigerant channels may include a first sub-refrigerant channel and a second sub-refrigerant channel. There can be multiple first sub-refrigerant channels, each extending along a first direction. These multiple first sub-refrigerant channels can be arranged sequentially along a second direction, with bends connecting them. A first sub-refrigerant channel located at one end of the multiple first sub-refrigerant channels can connect to a second sub-refrigerant channel. The second sub-refrigerant channel extends along the second direction. The overall arrangement of the first and second sub-refrigerant channels is neat and regular, which is beneficial for further increasing the number of sub-refrigerant channels per unit area of ​​the refrigerant flow section 142 and for further extending the length of the refrigerant channel 1421. When the second refrigeration unit 14... Figure 2 When setting the direction, the first direction is Figure 2 The X direction in the middle, the second direction is Figure 2 In the Y direction, the first direction and the second direction are perpendicular to each other. As an example, the refrigerant flow channel 1421 can be serpentine or spiral, etc.

[0053] The beverage flow channel can include multiple sub-beverage flow channels, which can be connected sequentially along the extension direction of the beverage flow channel. The multiple sub-beverage flow channels are connected sequentially, and any two adjacent sub-beverage flow channels are connected by bends. That is, any two adjacent sub-beverage flow channels are connected by bends. The multiple sub-beverage flow channels together form a continuous and bendable beverage flow channel. This is beneficial to increasing the number of sub-beverage flow channels per unit area of ​​the beverage flow section 143, extending the length of the beverage flow channel, increasing the heat exchange area of ​​the beverage flow section 143 and the heat exchange structure 141, improving the efficiency of the heat exchange coordination between the beverage in the beverage flow section 143 and the heat exchange structure 141, and further improving the working refrigeration efficiency of the second refrigeration unit 14.

[0054] As an example, multiple sub-beverage channels may include a first sub-beverage channel and a second sub-beverage channel. There can be multiple first sub-beverage channels, each extending along a first direction. These channels can be arranged sequentially along a second direction, with bends connecting them. First sub-beverage channels at their ends can connect to second sub-beverage channels, and these end-point channels can be bent and connected. The second sub-beverage channels extend along the second direction. The overall arrangement of the first and second sub-beverage channels is neat and regular, which helps to further increase the number of sub-beverage channels per 143 unit area of ​​the beverage flow section and further extend the length of the beverage flow channels. As an example, the beverage flow channels can be serpentine or spiral-shaped, etc.

[0055] In some embodiments of the present invention, the refrigerant flow section 142 is a capillary tube.

[0056] The refrigerant flow section 142 can be a capillary tube. The liquid refrigerant flowing from the condenser 12 to the refrigerant flow section 142 is a high-pressure, room-temperature liquid refrigerant. After the high-pressure, room-temperature liquid refrigerant enters the refrigerant flow section 142, which is constructed as a capillary tube, the pressure of the liquid refrigerant gradually decreases during the flow process due to the throttling effect. When the pressure of the liquid refrigerant drops below the corresponding saturation pressure, the liquid refrigerant begins to evaporate and absorb heat. During the evaporation process, the liquid refrigerant can absorb a large amount of heat, thereby further realizing the effect of heat exchange between the refrigerant and the beverage in the beverage flow channel through the heat exchange structure 141.

[0057] As an example, the refrigerant flow section 142 may include a plurality of first sub-refrigerant flow pipes 1422 and second sub-refrigerant flow pipes 1423. The first sub-refrigerant flow pipes 1422 can define a first sub-refrigerant flow channel, and the second sub-refrigerant flow pipes 1423 can define a second sub-refrigerant flow channel. This is beneficial to further realize the effect of refrigerant flowing in the refrigerant flow channel 1421 and to further realize the effect of extending the length of the refrigerant flow channel 1421.

[0058] As an example, the beverage flow section 143 can be a food-grade 304 stainless steel tube. The beverage flow section 143 can include multiple first sub-beverage flow tubes 1431 and second sub-beverage flow tubes 1432. The first sub-beverage flow tubes 1431 can define a first sub-beverage flow channel, and the second sub-beverage flow tubes 1432 can define a second sub-beverage flow channel, which is conducive to further realizing the effect of beverage flowing in the beverage flow channel and further realizing the effect of extending the length of the beverage flow channel.

[0059] In some embodiments of the present invention, the integrated refrigeration system may further include: a thermal insulation structure that covers at least a portion of the second refrigeration unit 14.

[0060] The insulation structure can cover at least a portion of the second refrigeration unit 14, and can be made of materials such as insulation cotton or insulation foam. The insulation structure can reduce the probability of the cooling capacity of the second refrigeration unit 14 being lost to the external environment, and can also reduce the impact of external heat on the second refrigeration unit 14, which helps to reduce the waste of cooling capacity of the second refrigeration unit 14 and further improve the cooling efficiency of the second refrigeration unit 14.

[0061] In some embodiments of the present invention, such as Figure 4 As shown, the vehicle-mounted multi-unit 1 may further include: a controller 300, which is communicatively connected to the vehicle-mounted beverage machine 100 and the refrigerant distribution unit 20. The controller 300 is configured to control the refrigerant distribution unit 20 to distribute the refrigerant flow into the first refrigeration unit 13 and the second refrigeration unit 14 according to the amount and temperature of the beverage required by the user.

[0062] The controller 300 can communicate with both the vehicle-mounted beverage machine 100 and the refrigerant distribution unit 20. Users can send the desired beverage quantity and temperature to the controller 300 through the vehicle-mounted beverage machine 100. For example, the vehicle-mounted beverage machine 100 can be equipped with a control panel 170, through which users can select the desired beverage quantity and temperature. The controller 300 is configured to control the refrigerant distribution unit 20 to distribute the refrigerant flow into the first refrigeration unit 13 and the second refrigeration unit 14 according to the user's desired beverage quantity and temperature. Specifically, the controller 300 can calculate the required refrigerant flow into the second refrigeration unit 14 based on the user's desired beverage quantity and temperature. The controller 300 then controls the refrigerant distribution unit 20 to distribute the refrigerant flow into the first refrigeration unit 13 and the second refrigeration unit 14 based on the calculated required refrigerant flow. This facilitates dynamic distribution of the refrigerant flow into the first and second refrigeration units 13 and 14, enables precise control of the refrigerant flow, improves the reliability of the vehicle-mounted multi-unit 1, ensures the second refrigeration unit 14 receives sufficient refrigerant, and allows the vehicle-mounted beverage machine 100 to output beverages with the quantity and temperature required by the user.

[0063] As an example, the liquid storage section 110 of the vehicle-mounted beverage machine 100 is equipped with a temperature sensor 160. The temperature sensor 160 can communicate with the controller 300. The temperature sensor 160 can send the temperature information of the beverage in the liquid storage section 110 to the controller 300. The controller 300 can calculate the refrigerant flow rate required by the second refrigeration unit 14 based on the temperature information of the beverage in the liquid storage section 110, the amount of beverage requested by the user, and the beverage temperature, which helps to improve the accuracy of the calculation results of the controller 300.

[0064] In some embodiments of the present invention, the controller 300 is further configured to control the refrigerant distribution unit 20 to distribute at least a portion of the refrigerant flowing out of the refrigerant distribution unit 20 into the second refrigeration unit 14 within a preset time period.

[0065] Within a preset time period, the controller 300 can control the refrigerant distribution unit 20 to distribute at least a portion of the refrigerant flowing out of the refrigerant distribution unit 20 into the second refrigeration unit 14. That is, the controller 300 can control the refrigerant distribution unit 20 to continuously distribute refrigerant to the second refrigeration unit 14 within the preset time period. Within the preset time period, when a user requests a cold drink, the controller 300 can control the refrigerant distribution unit 20 to prioritize distributing refrigerant into the second refrigeration unit 14, thus prioritizing the user's need for a cold drink. When the user has finished their requested amount of beverage and it is no longer within the preset time period, and the user no longer requests a cold drink from the vehicle-mounted beverage machine 100, the controller 300 can control the refrigerant distribution unit 20 to stop distributing refrigerant to the second refrigeration unit 14. The refrigerant can then be entirely supplied to the first refrigeration unit 13, allowing the first refrigeration unit 13 to refrigerate or freeze the vehicle-mounted refrigerator / warmer 200, thereby enabling the vehicle-mounted refrigerator / warmer 200 to be used for refrigerating or freezing food.

[0066] As an example, the controller 300 may have a memory function. By recording the user's usage habits, the controller 300 may be set to start the vehicle beverage machine 100 priority mode at a specific time. That is, the controller 300 controls the refrigerant distribution unit 20 to distribute at least a portion of the refrigerant flowing out of the refrigerant distribution unit 20 into the second refrigeration unit 14 within a preset time period.

[0067] In some embodiments of the present invention, such as Figure 4 As shown, the vehicle-mounted beverage machine 100 may include: a beverage flow detection structure 130, which is used to detect the beverage outflow flow of the vehicle-mounted beverage machine 100; a controller 300 is communicatively connected to the beverage flow detection structure 130; and the controller 300 is further configured to control the refrigerant distribution unit 20 to distribute all the refrigerant flowing out of the refrigerant distribution unit 20 into the first refrigeration unit 13 when the beverage outflow flow of the vehicle-mounted beverage machine 100 reaches a preset flow value.

[0068] The beverage flow detection structure 130 can be a flow meter. It can be located between the second refrigeration unit 14 and the liquid storage section 110. The beverage flow detection structure 130 can detect the outflow rate of the beverage from the vehicle-mounted beverage machine 100, meaning it can detect the amount of beverage consumed by the user. The controller 300 and the beverage flow detection structure 130 can communicate with each other, and the beverage flow detection structure 130 can send the detected outflow rate information of the vehicle-mounted beverage machine 100 to the controller 300. When the beverage flow detection structure 130 detects that the beverage outflow from the vehicle-mounted beverage machine 100 has reached the preset flow value, that is, when the beverage flow detection structure 130 of the vehicle-mounted beverage machine 100 meets the user's needs, the user no longer needs cold drinks. The controller 300 can control the refrigerant distribution unit 20 to distribute all the refrigerant flowing out of the refrigerant distribution unit 20 into the first refrigeration unit 13. The controller 300 can also control the refrigerant distribution unit 20 to stop supplying refrigerant to the second refrigeration unit 14. This helps to reduce the probability of refrigerant being distributed to the second refrigeration unit 14 when the vehicle-mounted beverage machine 100 does not need cold drinks, which helps to improve the utilization rate of refrigerant and further improve the working efficiency of the integrated refrigeration system.

[0069] As an example, the vehicle-mounted beverage machine 100 may also include a flow meter 150 disposed between the liquid storage section 110 and the second refrigeration unit 14. The flow meter 150 can be used to detect the flow rate of room temperature beverages flowing out of the liquid storage section 110. The flow meter 150 can be communicatively connected to the controller 300, which helps the controller 300 to determine whether the flow rate of beverages flowing into the second refrigeration unit 14 for heat exchange meets the user's needs, thereby reducing the probability that the flow rate of cold drinks flowing out of the liquid storage section 110 does not meet the user's needs.
