[0026] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] Example 1

[0029] Please refer to Figures 1 to 5 As shown, a vehicle-mounted refrigerator mixed-flow refrigeration system includes a refrigerator body 1.

[0030] Specifically, the refrigerator body 1 has an internal storage space for storing items.

[0031] Mixed-flow refrigeration systems include:

[0032] Cooling cycle components are used to absorb heat from the interior of a space to achieve a cooling effect.

[0033] The mixing component is located inside the refrigerator body 1 and is connected to the storage space. It is used to make the cold air flow inside the storage space. This can accelerate the cooling speed inside the storage space and make the temperature inside the storage space more uniform through the flow of cold air.

[0034] The refrigerator body 1 has an inner liner inside, and an installation space is formed between the refrigerator body 1 and the inner liner. The mixing component is installed inside the installation space and is connected to the receiving space.

[0035] like Figure 3 and Figure 4 As shown, the mixing assembly includes an air guide shroud 15 and a first fan 14. The air guide shroud 15 is disposed on the inner liner of the refrigerator. The inner liner of the refrigerator has at least one air outlet 12 and one air inlet 13. The air outlet 12 and the air inlet 13 are used to connect the accommodating space and the internal space of the air guide shroud 15. The first fan 14 is disposed inside the air guide shroud 15. The first fan 14 has an intake end and an exhaust end. The intake end is close to the air inlet 13, and the exhaust end is close to the air outlet 12. The first fan 14 is used to make the gas in the inner liner of the refrigerator flow, and the gas circulates between the accommodating space and the internal space of the air guide shroud 15.

[0036] Specifically, the first fan 14 is electrically connected to the vehicle power supply. When the first fan 14 is started, the gas inside the air guide shroud 15 enters the receiving space through the air outlet 12, causing the gas in the receiving space to flow. Then, the gas enters the air guide shroud 15 through the air inlet 13, allowing the gas to circulate between the receiving space and the air guide shroud 15. This gas circulation accelerates the heat transfer speed in the receiving space, further enhancing the cooling effect and making the temperature in the receiving space more uniform. In other embodiments of this application, the air guide shroud 15 and the first fan 14 can also be arranged inside the receiving space. The air outlet 12 and the air inlet 13 are opened on the air guide shroud 15. The specific location can be set according to the actual situation. This application does not make any special limitation on where they are set in the installation space or the receiving space. Similarly, the number, size, position, and shape of the air outlet 12 and the air inlet 13 can be set according to the actual situation, and this application does not make any special limitation.

[0037] Furthermore, in this application, to facilitate the use of the vehicle refrigerator by passengers in various locations, two compartments are provided. Specifically, the refrigerator body 1 includes a first compartment 3 and a second compartment 4 arranged in a first direction. The second compartment 4 is fixedly mounted on the top of the first compartment 3. A first receiving slot 5 is provided inside the first compartment 3, and a second receiving slot 6 is provided inside the second compartment 4. The first receiving slot 5 and the second receiving slot 6 are connected to each other, forming a receiving space. A top cover 21 is provided on the top of the second compartment 4. The first direction is... Figure 5 In the vertical direction;

[0038] Furthermore, the first compartment 3 has a first side wall with an opening that communicates with the first receiving slot 5. The drawer 2 is movably disposed within the first receiving slot 5 and can be moved out of the first receiving slot 5 to hold items. The top of the drawer 2 is open, and the drawer 2 is provided with several air vents 16 that allow airflow to pass through, so that cold air can enter the interior of the drawer 2. Passengers in the front row can open the top cover 21 to take items out of the receiving space, while passengers in the rear row can take items out of the drawer 2. By setting up two compartments, passengers in each position can conveniently use the car refrigerator.

[0039] like Figures 2 to 4 As shown, the first box 3 is also provided with a first inner liner that is adapted to the first box 3. The first box 3 and the first inner liner are fixed by a first end cap 8, which is located at the opening.

[0040] Furthermore, the first inner liner includes a first inner liner body 7 and an inner liner bottom 11. The inner liner bottom 11 is located at the end of the first inner liner body 7 away from the opening, and an air outlet 12 communicating with the interior of the first inner liner body 7 is provided at its upper part.

[0041] The second housing 4 is also provided with a second inner liner 9 that is adapted to the second housing 4. The second housing 4 and the second inner liner 9 are fixed by a second end cap 10. The second end cap 10 is located on the top of the second inner liner 9. After the second inner liner 9 and the second housing 4 are fixed by the second end cap 10, they are closed by the top cover 21. The first housing 3 and the first inner liner, as well as the second housing 4 and the second inner liner 9, together form an installation space; the first inner liner and the second inner liner 9 are connected.

[0042] Furthermore, an air intake vent 13, which connects to the interior of the second inner liner 9, is provided at the lower part of the second inner liner 9.

[0043] The air guide shroud 15 is set on the side wall of the bottom of the inner liner 11 away from the opening, and the two ends of the air guide shroud 15 are connected to the air inlet 13 and the air outlet 12 respectively.

[0044] The first fan 14 is disposed inside the air guide shroud 15. The first fan 14 has an intake end and an exhaust end. The intake end is close to the air intake 13 and the exhaust end is close to the air outlet 12.

[0045] During assembly, the bottom 11 of the inner liner is first installed on the first inner liner body to assemble the first inner liner. Then the first inner liner is installed into the first box 3. Next, the second inner liner 9 is installed on the top of the first inner liner. Then the air guide shroud 15 is installed on the first inner liner and the second inner liner 9 so that the air guide shroud 15 covers the air intake 13 and the air blowing 12. Then the second box 4 is installed on the top of the first box 3. After that, the first end cap 8 fixes the first inner liner and the first box 3 and closes them with the top cap 21. The second end cap 10 fixes the second inner liner 9 and the second box 4.

[0046] Thus, by activating the first fan 14, air inside the second inner liner 9 can be drawn into the air guide shroud 15 and blown into the first inner liner, forming a gas circulation.

[0047] The refrigeration cycle assembly can cool the inside of the refrigerator liner;

[0048] Specifically, such as Figure 2 , Figure 3 and Figure 5 As shown, the refrigeration cycle assembly includes a mounting bracket 17, which is disposed on the side of the first housing 3 away from the opening;

[0049] Furthermore, the refrigeration cycle assembly also includes a compressor 18, which is disposed inside the mounting bracket 17 and contains refrigerant. The compressor 18 is used to convert the refrigerant into a high-temperature and high-pressure gas.

[0050] Furthermore, the refrigeration cycle assembly also includes a condenser 19, which is located on top of the mounting bracket 17 and is connected to the compressor 18. The compressor 18 converts the refrigerant into a high-temperature and high-pressure gas. After the gas enters the condenser 19, it exchanges heat with the outside air, releases heat, and transforms into a high-pressure liquid.

[0051] Furthermore, the refrigeration cycle assembly also includes a throttling element 23, one end of which is connected to the condenser 19 to convert the high-pressure liquid into a low-temperature, low-pressure liquid; optionally, the throttling element 23 is a capillary tube or an expansion valve; a dryer filter can also be provided between the throttling element and the condenser to filter impurities and moisture in the refrigerant.

[0052] Furthermore, the refrigeration cycle assembly also includes an evaporator 20, which is disposed in the installation space and in contact with the side walls of the first inner liner and the second inner liner 9. The evaporator 20 has a continuous S-shaped structure, which can increase the contact area with the side walls of the first inner liner and the second inner liner 9. One end of the evaporator 20 is connected to the end of the throttling device 23 away from the condenser 19, and the other end is connected to the compressor 18. Low-temperature and low-pressure liquid enters the evaporator 20, absorbs the heat inside the first cabinet 3 and the second cabinet 4 and evaporates into gas, which can cool the inside of the refrigerator body 1, thereby completing the refrigeration cycle and returning to the compressor 18.

[0053] It should be noted that the refrigeration cycle assembly also includes a second fan 22. The second fan 22 is located at the bottom of the condenser 19, between the condenser 19 and the compressor 18. The second fan 22 draws air from the side near the compressor 18 and blows it toward the condenser 19. Alternatively, it can draw air from the side near the condenser 19 and blow it toward the compressor 18 to assist in the heat dissipation of the compressor 18 and the condenser 19. It can also be located on the same side of the condenser 19 and the compressor 18 to draw in outside air and blow it toward the compressor 18 and the condenser 19, or to blow the air around the compressor 18 and the condenser 19 to the outside.

[0054] It should be noted that the installation space is filled with foam, which can keep the environment inside the refrigerator liner warm. At the same time, the foam can also seal the gap between the air guide shroud 15, the first inner liner and the second inner liner 9, and fix the evaporator 20.

[0055] Example 2

[0056] This embodiment provides a vehicle-mounted refrigerator that uses the mixed-flow refrigeration system described in Embodiment 1.

[0057] Working principle: When cooling the interior of the refrigerator body 1, the compressor 18 is activated by starting the refrigeration cycle assembly to convert the refrigerant into a high-temperature and high-pressure gas. The gas then enters the condenser 19 and is converted into a high-pressure liquid. Subsequently, the high-pressure liquid passes through the throttling device 23 and is converted into a low-temperature and low-pressure liquid. The liquid enters the evaporator 20. Since the evaporator 20 has a continuous S-shaped structure and is in contact with the side walls of the first inner liner and the second inner liner 9, the liquid can exchange heat with the first inner liner and the second inner liner 9, absorb heat, and achieve cooling of the interior of the first cabinet 3 and the second cabinet 4. After absorbing heat, the liquid evaporates into gas and returns to the compressor 18, thus completing the refrigeration cycle.

[0058] By activating the first fan 14, the cold air inside the second compartment 4 can be absorbed into the air guide shroud 15 and then discharged into the first compartment 3 through the air outlet 12. The cold air enters the drawer 2 through the flow port 16 to cool the items inside the drawer 2. At the same time, the first fan 14 can make the cold air flow inside the refrigerator body 1, so that the cold air is evenly distributed inside the refrigerator body 1.

[0059] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
