[0051] In order to illustrate the technical solution of the present application, a description is given below with reference to specific drawings and embodiments.

[0052] In a traditional vehicle refrigerator module, a compressor, condenser, expansion valve, cooling fan, sensor and other devices need to be separately installed in the refrigerator, which not only consumes high energy and continuously consumes the vehicle power supply, but also occupies a large space and has a low actual usable area. In addition, the heat emitted by the condenser in the refrigerator can only be dissipated into the passenger compartment, increasing the heat load in the passenger compartment, increasing the air conditioning energy consumption, and poor comfort. In order to overcome the above technical problems, the present application proposes a vehicle refrigerator module, a heat circulation system and a vehicle.

[0053] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 is a schematic diagram of a thermal cycle system in the first embodiment of the present application, Figure 2 yes Figure 1 The schematic diagram of the structure of the refrigerator 10 in the thermal cycle system shown in FIG. Figure 3 yes Figure 1 Schematic diagram of the thermal cycle system shown.

[0054] In a first aspect, a first embodiment of the present application provides a vehicle refrigerator module 100 for use in a vehicle, wherein the vehicle includes a thermal management module 200 having a refrigerant pipeline 210 for circulation of a refrigerant (not shown in the figure).

[0055] The thermal management module 200 may include a refrigerant pipeline 210, a compressor 220, an air conditioning assembly 230, and a seat heating assembly (not shown in the figure). The refrigerant flows in the refrigerant pipeline 210 to realize the cooling function of the air conditioning assembly 230 and the heating function of the seat heating assembly. The refrigerant may be propane, hydrocarbons, 1,1,1,2-tetrafluoroethane, 2,3,3,3-tetrafluoropropylene, and the like.

[0056] The vehicle refrigerator module 100 includes a refrigerator 10 and a first heat exchange element 20 .

[0057] The refrigerator 10 includes a shell 11 and a cold storage assembly 12 . A first accommodating cavity 111 is provided inside the shell 11 . The cold storage assembly 12 is located inside the shell 11 . The cold storage assembly 12 is used to reduce the temperature inside the first accommodating cavity 111 .

[0058] The first accommodating chamber 111 may contain food, beverages, medicines, or other items that need to be refrigerated and kept warm. The cold storage assembly 12 may lower the temperature in the first accommodating chamber 111 after exchanging heat and cold with the gas in the first accommodating chamber 111 or the outer wall of the first accommodating chamber 111 .

[0059] The first heat exchange element 20 is used to perform heat exchange between the refrigerant in the refrigerant pipeline 210 and the cold storage assembly 12 .

[0060] It can be understood that after the refrigerant in the refrigerant pipeline 210 exchanges heat with the cold storage component 12 , the temperature of the refrigerant in the refrigerant pipeline 210 increases, and the temperature of the cold storage component 12 decreases and can be used to reduce the temperature in the first accommodating chamber 111 .

[0061] The first heat exchange element 20 may be a plate heat exchanger, a tube heat exchanger or a spray heat exchanger.

[0062] From the above, it can be seen that the vehicle refrigerator module 100 provided in the embodiment of the present application, since the refrigerator 10 includes a shell 11 and a cold storage component 12, a first accommodating chamber 111 is arranged inside the shell 11, and the cold storage component 12 is located inside the shell 11. The cold storage component 12 is used to reduce the temperature in the first accommodating chamber 111, and the first heat exchange component 20 is used to perform heat exchange between the refrigerant pipeline 210 and the cold storage component 12. Therefore, the refrigerant in the refrigerant pipeline 210 of the thermal management module 200 in the vehicle can be exchanged with the cold storage component 12 through the first heat exchange component 20, so that the cold storage component 12 has a lower temperature, and the temperature in the first accommodating chamber 111 can be reduced through the cold storage component 12 to meet the refrigeration demand of the refrigerator 10. The vehicle refrigerator module 100 provided in the embodiment of the present application can meet the refrigeration needs of the refrigerator 10 by utilizing the refrigerant pipeline 210 of the vehicle's own thermal management module 200, and does not need to separately set up components such as a compressor, a condenser, an expansion valve, a cooling fan and a sensor. Therefore, the energy consumption is low, the space occupied is small, and the comfort of passengers in the vehicle will not be affected.

[0063] The vehicle refrigerator module 100 provided in the embodiment of the present application solves the problems of high cost of vehicle refrigerators (can significantly reduce the cost of vehicle refrigerators, and the cost reduction is expected to be more than 70%), difficulty in layout (diversified and randomized layout), single layout structure, high NVH (Noise, Vibration, Harshness) caused by the fan of the vehicle refrigerator's own compressor (NVH is expected to be reduced to 0), high heat dissipation (no heat dissipation into the passenger compartment), and low volumetric efficiency (it is expected to be able to increase the volume ratio to more than 80%). It solves the energy consumption problem of vehicle refrigerators, and the energy consumption is expected to be reduced to less than 80% of the energy consumption of traditional vehicle refrigerators.

[0064] In a traditional car refrigerator, since a compressor, condenser, expansion valve, cooling fan, sensor and other components need to be separately provided, the compressor of the car refrigerator itself cannot operate in a high temperature environment (such as the temperature inside the vehicle is greater than 60°C), resulting in the car refrigerator not being able to work in a high temperature environment. The car refrigerator module 100 provided in the embodiment of the present application can meet the refrigeration demand of the refrigerator 10 by using the refrigerant pipeline 210 of the vehicle's own thermal management module 200, and does not need to be separately provided with a compressor, condenser, expansion valve, cooling fan, sensor and other components for the refrigerator, and can work normally in a high temperature environment.

[0065] Whether the vehicle refrigerator module 100, the air conditioning component 230 and the seat heating component provided in the embodiment of the present application are working or not will not affect the independent operation of the vehicle refrigerator module 100, and the impact on the thermal management module 200 is minimized.

[0066] Please continue to refer to Figure 1 , Figure 2 and Figure 3 In this embodiment, the cold storage component 12 is provided with a cold storage pipeline 121 and a cold storage medium (not shown in the figure), and a circulating liquid (not shown in the figure) is provided in the cold storage pipeline 121. The circulating liquid can exchange heat with the cold storage medium, and the cold storage medium is used to reduce the temperature in the first accommodating chamber 111.

[0067] The first heat exchange element 20 is provided with a first channel 21 and a second channel 22. The first channel 21 is used to be connected to the refrigerant pipeline 210, and the second channel 22 is connected to the cold storage pipeline 121. The first heat exchange element 20 is used to exchange heat between the refrigerant in the first channel 21 and the circulating fluid in the second channel 22.

[0068] The vehicle refrigerator module 100 includes a circulation pump 30 , which is connected to the cold storage pipeline 121 . The circulation pump 30 is used to circulate the circulating fluid in the cold storage pipeline 121 and the second channel 22 .

[0069] By adopting the above scheme, when the circulating pump 30 causes the circulating liquid to circulate in the cold storage pipeline 121 and the second channel 22, the first heat exchange element 20 can be used to exchange heat between the first channel 21 and the second channel 22, thereby completing the heat exchange between the circulating liquid in the cold storage pipeline 121 and the refrigerant in the refrigerant pipeline 210, so that the cold storage medium can have a lower temperature, and then the temperature in the first accommodating chamber 111 can be lowered by the cold storage medium to meet the refrigeration demand of the refrigerator 10.

[0070] Optionally, the vehicle refrigerator module 100 includes a heat preservation pipe (not shown in the figure), and the second channel 22 is connected to the cold storage pipeline 121 through the heat preservation pipe. In this way, when the circulating liquid after the heat exchange with the refrigerant flows from the second channel 22 to the cold storage pipeline 121, it is possible to avoid a large degree of heat exchange between the circulating liquid and the air outside the vehicle refrigerator module 100, resulting in a significant change in the temperature of the circulating liquid, which affects the effect of the subsequent cold storage component 12 to reduce the temperature in the first accommodating chamber 111.

[0071] Among them, the refrigerant temperature in the first channel 21 can generally be controlled between -28°C and 15°C. When the air conditioning component 230 and the seat heating component are working, the refrigerant temperature in the first channel 21 can generally be controlled between 0°C and 5°C. The flow rate of the circulating liquid in the second channel 22 can be smaller, and the difference between the temperature of the circulating liquid flowing out of the second channel 22 and the temperature of the refrigerant in the first channel 21 can be within 2°C, which can meet the cooling capacity required by the refrigerator 10. The refrigeration temperature in the first accommodating chamber 111 of the refrigerator 10 can be -25°C to 30°C. If the heating function of the refrigerator 10 is to be realized, a heating wire can be arranged inside the shell 11 of the refrigerator 10, so that the heating temperature in the first accommodating chamber 111 of the refrigerator 10 can be above 55°C.

[0072] For example, the first channel 21 is used to be connected in series with the refrigerant pipeline 210. The cold storage pipeline 121 has a liquid inlet 1211 and a liquid outlet 1212. The cold storage pipeline 121 is connected to the second channel 22 through the liquid inlet 1211 and the liquid outlet 1212, and forms a cold storage circuit with the circulating pump 30. The circulating liquid can be a mixture of water and ethylene glycol, etc.

[0073] The material of the cold storage medium is one of Na2SO4·10H2O, NH4Cl and KCl. This arrangement facilitates the preparation of the cold storage medium.

[0074] It is understandable that in other embodiments, the cold storage medium may also be made of other materials.

[0075] In this embodiment, the cold storage component 12 includes a heat exchanger 122, and the cold storage pipeline 121 is arranged in the heat exchanger 122. The heat exchanger is provided with a containing pipeline (not shown in the figure), and the cold storage medium is arranged in the containing pipeline. Such a configuration can make the structure of the cold storage component 12 simpler, and the temperature in the first containing chamber 111 can be reduced by the cold storage medium to meet the refrigeration demand of the refrigerator 10.

[0076] As another practicable manner, the cold storage medium is disposed on the outer surface of the cold storage pipeline 121, and the cold storage medium can fill the inner space of the shell 11. For example, the cold storage medium can wrap the heat exchanger 122 inside.

[0077] It should be noted that the heat exchanger 122 may be a plate heat exchanger, a tubular heat exchanger or a spray heat exchanger, etc. A circulating fluid is provided in the heat exchanger 122. After the refrigerant in the refrigerant pipeline 210 exchanges heat with the circulating fluid in the heat exchanger 122, the temperature of the refrigerant in the refrigerant pipeline 210 increases, and the temperature of the circulating fluid in the heat exchanger 122 decreases. The cold storage medium can lower its own temperature after exchanging heat with the circulating fluid in the heat exchanger 122, and further lower the temperature in the first accommodating chamber 111 after exchanging heat with the gas in the first accommodating chamber 111 or the outer wall of the first accommodating chamber 111.

[0078] Optionally, at least two heat exchangers 122 are provided, and the two heat exchangers 122 are respectively provided on both sides of the first accommodation chamber 111. Such a configuration can allow the circulating fluid in the heat exchanger 122 to exchange heat with the cold storage medium more quickly, thereby being able to more quickly reduce the temperature in the first accommodation chamber 111 through the cold storage medium.

[0079] It should be noted that, considering that the refrigerator 10 is provided with a refrigerator door, a refrigerator door can be provided on one side of the first accommodating chamber 111, and heat exchangers 122 and cold storage medium are provided on the other sides of the first accommodating chamber 111, and the circulating fluid in each heat exchanger 122 can exchange heat with the cold storage medium. The cold storage pipelines 121 of all heat exchangers 122 are connected in series.

[0080] Please refer to Figure 1 , Figure 2 and Figure 3 In order to enable the cold storage component 12 to more quickly reduce the temperature in the first accommodating chamber 111, in this embodiment, the refrigerator 10 includes a temperature regulating fan 40, and the air outlet direction of the temperature regulating fan 40 is from the cold storage component 12 toward the first accommodating chamber 111.

[0081] By adopting the above scheme, the wind blown by the temperature regulating fan 40 can be used to bring the cold energy of the cold storage component 12 to the outer wall of the first accommodating chamber 111, thereby accelerating the heat exchange rate between the cold storage component 12 and the gas in the first accommodating chamber 111, and the temperature in the first accommodating chamber 111 can be reduced more quickly.

[0082] The temperature regulating fan 40 allows the air to be discharged in a direction from the cold storage medium toward the first accommodating chamber 111 .

[0083] For example, the shell 11 is provided with a second accommodating chamber 112 located inside the shell 11, the cold storage component 12 is provided in the second accommodating chamber 112, the temperature regulating fan 40 has an air outlet (not shown in the figure), and the temperature regulating fan 40 discharges air through the air outlet; the shell 11 is provided with an air inlet (not shown in the figure) connected to the second accommodating chamber 112, the air inlet is located on the side of the cold storage component 12 away from the first accommodating chamber 111, the temperature regulating fan 40 is provided outside the shell 11, and the air outlet is connected to the air inlet. In this way, the temperature regulating fan 40 can be used to discharge air into the entire second accommodating chamber 112 through the air inlet of the second accommodating chamber 112, and the air is blown from the cold storage component 12 to the first accommodating chamber 111, thereby accelerating the cold and heat exchange rate between the cold storage component 12 and the gas in the first accommodating chamber 111 or the outer wall of the first accommodating chamber 111, so that the temperature in the first accommodating chamber 111 can be reduced more quickly.

[0084] It is understandable that the temperature control fan 40 can be electrically connected to the control module of the vehicle, and the start and stop of the temperature control fan 40 can be controlled by the control module. When multiple cold storage components 12 are provided in the second accommodating chamber 112, only one temperature control fan 40 is required to accelerate the heat exchange rate between all cold storage components 12 and the gas in the first accommodating chamber 111. The housing 11 can be provided with an exhaust hole, and the wind blown into the second accommodating chamber 112 by the temperature control fan 40 can be discharged from the second accommodating chamber 112 through the exhaust hole (not shown in the figure) after being blown from the cold storage component 12 to the first accommodating chamber 111.

[0085] Optionally, the refrigerator 10 is provided with a heat preservation layer 113, and the heat preservation layer 113 is located on a side of the cold storage component 12 away from the first accommodation chamber 111. Such a configuration can avoid a large degree of cold and heat exchange between the cold storage component 12 and the air of the shell 11, resulting in a significant change in the temperature of the cold storage component 12, which affects the subsequent cold storage component 12 to reduce the temperature in the first accommodation chamber 111.

[0086] It can be understood that the thermal insulation layer 113 can be disposed on the outer surface of the shell 11 .

[0087] Please refer to Figure 1 , Figure 2 and Figure 3 In the second aspect, the first embodiment of the present application provides a thermal cycle system, including a thermal management module 200 and a vehicle refrigerator module 100 as in the first aspect. The thermal management module 200 is provided with a refrigerant pipeline 210; the first heat exchange component 20 is used to perform heat and cold exchange between the refrigerant pipeline 210 and the cold storage component 12.

[0088] The thermal circulation system provided in the embodiment of the present application includes a thermal management module 200 and a vehicle-mounted refrigerator module 100. The refrigerator 10 in the vehicle-mounted refrigerator module 100 includes a shell 11 and a cold storage component 12. A first accommodating chamber 111 is provided inside the shell 11. The cold storage component 12 is located inside the shell 11. The cold storage component 12 is used to reduce the temperature inside the first accommodating chamber 111, and the first heat exchange component 20 is used to perform heat exchange between the refrigerant in the refrigerant pipeline 210 and the cold storage component 12. Therefore, the refrigerant in the refrigerant pipeline 210 of the thermal management module 200 in the vehicle and the cold storage component 12 can be exchanged between the first heat exchange component 20, so that the cold storage component 12 has a lower temperature, and the temperature inside the first accommodating chamber 111 can be reduced by the cold storage component 12 to meet the refrigeration demand of the refrigerator 10. The thermal circulation system provided in the embodiment of the present application can meet the refrigeration needs of the refrigerator 10 by utilizing the refrigerant pipeline 210 of the vehicle's own thermal management module 200, and does not need to separately set up components such as a compressor, condenser, expansion valve, cooling fan and sensor. Therefore, the energy consumption is low, the space occupied is small, and it will not affect the comfort of passengers in the vehicle.

[0089] In this embodiment, the thermal circulation system further includes a battery cooling module 300 , which has a cooling pipeline 310 for circulating coolant, and the first heat exchange element 20 is used to perform heat exchange between the refrigerant in the refrigerant pipeline 210 and the coolant in the cooling pipeline 310 .

[0090] By adopting the above-mentioned scheme, the refrigerant in the refrigerant pipeline 210 of the thermal management module 200 in the vehicle can be exchanged with the cold storage component 12 through the first heat exchange component 20 to meet the refrigeration demand of the refrigerator 10. At the same time, the refrigerant in the refrigerant pipeline 210 of the thermal management module 200 in the vehicle can be exchanged with the coolant in the cooling pipeline 310 through the first heat exchange component 20 to meet the cooling demand of the battery cooling module 300, such as cooling the battery and the motor.

[0091] For example, the first heat exchange element 20 is provided with a third channel 23, the third channel 23 is connected to the cooling pipeline 310, and the first heat exchange element 20 is used to perform heat exchange between the refrigerant in the refrigerant pipeline 210 and the coolant in the third channel 23. Such a configuration can facilitate heat exchange between the refrigerant in the refrigerant pipeline 210 of the thermal management module 200 in the vehicle and the coolant in the cooling pipeline 310.

[0092] The coolant may be a mixture of water and ethylene glycol, etc. The flow rate of the coolant in the third channel 23 may be relatively large, and the temperature of the coolant flowing out of the third channel 23 may be relatively high, as long as it can meet the cooling requirements of the battery cooling module 300 .

[0093] Specifically, the refrigerant in the first channel 21 exchanges heat with the coolant in the third channel 23. The first heat exchange element 20 may be provided with six interfaces (not shown), and the first channel 21, the second channel 22 and the third channel 23 correspond to two interfaces respectively.

[0094] It is understandable that by adjusting the lengths of the first channel 21, the second channel 22 and the third channel 23, the circulating liquid in the second channel 22 and the cooling liquid in the third channel 23 can have two different temperatures, which not only meets the cooling requirements of the battery cooling module 300, but also meets the cooling temperature required by the refrigerator 10.

[0095] Please refer to Figure 3 The refrigerant pipeline 210 connected to the first heat exchange element 20 and the refrigerant pipeline 210 connected to the first channel 21 of the air conditioning component 230 are arranged in parallel. In other embodiments, the first heat exchange element 20 can also be connected to other parts of the refrigerant pipeline 210.

[0096] In a third aspect, an embodiment of the present application provides a vehicle, the vehicle comprising a thermal cycle system as in the second aspect.

[0097] The vehicle provided in the embodiment of the present application has a thermal circulation system including a thermal management module 200 and a vehicle-mounted refrigerator module 100. The refrigerator 10 in the vehicle-mounted refrigerator module 100 includes a shell 11 and a cold storage component 12. A first accommodating chamber 111 is provided inside the shell 11.
