[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0045] Embodiments of this application provide a refrigerator 100, such as Figures 1 to 3 As shown, the refrigerator 100 includes a cabinet, two inner liners, and two heat exchangers. The refrigerator 100 can be a vehicle refrigerator.

[0046] The refrigerator comprises a first inner liner 1 and a second inner liner 4. The first inner liner 1 has a first storage space, and the second inner liner 4 has a second storage space. The first inner liner 1 and the second inner liner 4 are stacked along the height of the refrigerator body and disposed inside the refrigerator body to facilitate the overall miniaturization of the refrigerator design and reduce the space occupied in the passenger compartment of the vehicle. The first inner liner 1 is closer to the floor of the passenger compartment of the vehicle than the second inner liner 4. In other alternative embodiments, the first inner liner 1 and the second inner liner 4 can be arranged side by side along the length or width of the refrigerator body.

[0047] The two heat exchangers include a first heat exchanger 2 and a second heat exchanger 5, wherein the first heat exchanger 2 is configured to surround a portion of the first inner liner 1 to regulate the temperature of the first inner liner 1, and the second heat exchanger 5 is configured to surround a portion of the second inner liner 4 to regulate the temperature of the second inner liner 4.

[0048] The first heat exchanger 2 and the second heat exchanger 5 are configured to independently distribute the heat exchange medium to independently regulate the temperature of the first item storage space and the second item storage space.

[0049] Understandably, since the first heat exchanger 2 and the second heat exchanger 5 are configured to independently distribute the heat exchange medium to independently adjust the temperature of the first and second item storage spaces, the first and second item storage spaces can achieve independent temperature control, allowing them to adjust their temperature according to the storage temperature requirements of the stored items. For example, the temperature of the first inner liner 1 can be set lower than the temperature of the second inner liner 4, so that the first inner liner 1 is used for freezing items and the second inner liner 4 is used for refrigerating items. Alternatively, at least one of the first inner liner 1 and the second inner liner 4 may also have a heating function.

[0050] In one specific implementation, both the first heat exchanger 2 and the second heat exchanger 5 are configured as heat exchange tubes, such that the first heat exchanger 2, which provides cooling to the first inner liner 1, is configured as a tubular structure, and the second heat exchanger 5, which provides cooling to the second inner liner 4, is configured as a tubular structure. The tubular heat exchanger has a mature technology, simple structure, and low cost. At the same time, the tubular heat exchanger can accept a large flow rate of heat exchange medium.

[0051] In some embodiments, continue to refer to Figures 1 to 3 and Figure 6 The first heat exchanger 2 includes a first heat exchanger inlet pipe 21, a first heat exchanger outlet pipe 22, and multiple sections of first coil 23 connected between the first heat exchanger inlet pipe 21 and the first heat exchanger outlet pipe 22. The multiple sections of first coil 23 are configured to surround a portion of the first inner liner 1 to cool the first inner liner 1. The heat exchange medium enters the multiple sections of first coil 23 through the first heat exchanger inlet pipe 21 to cool the first inner liner 1, and the heat exchange medium after heat exchange flows out through the first heat exchanger outlet pipe 22.

[0052] The second heat exchanger 5 includes a second heat exchanger inlet pipe 51, a second heat exchanger outlet pipe 52, and multiple sections of second coil 53 connected between the second heat exchanger inlet pipe 51 and the second heat exchanger outlet pipe 52. The multiple sections of second coil 53 are configured to surround a portion of the second inner liner 4 to cool the second inner liner 4. The heat exchange medium enters the multiple sections of second coil through the second heat exchanger inlet pipe 51 to cool the second inner liner 4, and the heat exchange medium after heat exchange flows out through the second heat exchanger outlet pipe 52.

[0053] The refrigerator also includes a first control valve 3, which has a first interface and a second interface. The first interface is connected to the inflow pipe 21 of the first heat exchanger, and the second interface is connected to the inflow pipe 51 of the second heat exchanger. The flow rate of the heat exchange medium flowing into the first heat exchanger 2 is adjusted by controlling the flow rate of the first interface of the first control valve 3, and the flow rate of the heat exchange medium flowing into the second heat exchanger 5 is adjusted by controlling the flow rate of the second interface of the first control valve 3.

[0054] The first heat exchanger inlet pipe 21 and the second heat exchanger inlet pipe 51 share a first control valve 3, which can reduce the use of the first control valve 3.

[0055] The refrigerator also includes a first connecting pipe 211, which is provided with a heat exchange medium inlet. The first control valve 3 is a multi-way valve. Specifically, the first control valve 3 includes a first interface, a second interface and a third interface. The first interface of the first control valve 3 is connected to the first connecting pipe 211, the second interface of the first control valve 3 is connected to the first heat exchanger inlet pipe 21, and the third interface of the first control valve 3 is connected to the second heat exchanger inlet pipe 51.

[0056] After the heat exchange medium enters the first connecting pipe 211, it enters the first control valve 3. At the first control valve 3, the flow is split, with part of the heat exchange medium entering the first heat exchanger inlet pipe 21 and part of the heat exchange medium entering the second heat exchanger inlet pipe 51.

[0057] The first connecting pipe 211 is set close to the first inner liner 1. Since the refrigerator is installed in the passenger compartment, the first inner liner 1 and the second inner liner 4 are stacked along the height direction of the refrigerator. The first inner liner 1 is closer to the passenger compartment floor of the vehicle than the second inner liner 4. Therefore, arranging the inlet pipe of the heat exchange medium at the first inner liner 1 is more conducive to simplifying the pipe arrangement of the heat exchange components of the refrigerator.

[0058] In some embodiments, the refrigerator further includes a second control valve 6, wherein the second control valve 6 has a first interface and a second interface, the first interface is connected to the outlet pipe 22 of the first heat exchanger, and the second interface is connected to the outlet pipe 52 of the second heat exchanger. The flow rate of the heat exchange medium flowing out of the first heat exchanger 2 is adjusted by controlling the flow rate of the first interface of the second control valve 6, and the flow rate of the heat exchange medium flowing out of the second heat exchanger 5 is adjusted by controlling the flow rate of the second interface of the second control valve 6.

[0059] The first heat exchanger outlet pipe 22 and the second heat exchanger outlet pipe 52 share a second control valve 6, which can reduce the use of the second control valve 6.

[0060] In one specific implementation, the refrigerator also includes a third connecting pipe 221, which has a heat exchange medium outlet. The second control valve 6 is configured as a multi-way valve, for example, a three-way valve. The second control valve 6 includes a first interface, a second interface, and a third interface. The first interface of the second control valve 6 is connected to the outlet pipe 22 of the first heat exchange element, the second interface of the second control valve 6 is connected to the outlet pipe 52 of the second heat exchange element, and the third interface of the second control valve 6 is connected to the third connecting pipe 221.

[0061] After the heat exchange is completed, part of the heat exchange medium flows into the second control valve 6 through the outlet pipe 52 of the second heat exchange element, and part of the heat exchange medium flows into the second control valve 6 through the outlet pipe 22 of the first heat exchange element. After they merge, they flow into the third connecting pipe 221 and flow out through the heat exchange medium outlet.

[0062] Since the first heat exchanger 2 and the second heat exchanger 5 share a single heat exchange medium outlet pipe, the length of the outlet pipe can be effectively reduced, decreasing the space required for pipe routing within the vehicle and lowering costs. Simultaneously, because the temperature of the heat exchange medium flowing out from the first heat exchanger 2 and the second heat exchanger 5 is relatively low, reducing the use of the outlet pipe helps lower the risk of condensation forming on the outside of the outlet pipe.

[0063] In some embodiments, the first inner liner 1 is provided with a first item storage space, and the second inner liner 4 is provided with a second item storage space. In one embodiment, the first item storage space is configured to store refrigerated, frozen, or heated items, and the second item storage space is configured to store frozen, refrigerated, or heated items.

[0064] In some embodiments, such as Figure 1 , Figure 4 and Figure 5 As shown, the first inner liner 1 includes multiple first inner liner side surfaces 11, a first inner liner top surface 13, and a first inner liner bottom surface 14. The first inner liner top surface 13 is connected to the multiple first inner liner side surfaces 11, and the first inner liner bottom surface 14 is connected to the multiple first inner liner side surfaces 11. The first inner liner 1 also has a first inner liner opening 12, which corresponds to one of the first inner liner side surfaces 11.

[0065] The first inner liner 1 is further provided with a drawer 7, which has storage space for the first item. The drawer 7 is slidably installed on the inner wall of the first inner liner 1 through the opening 12 of the first inner liner. By providing the opening 12 of the first inner liner on the side of the first inner liner 1, it is convenient for passengers in the rear of the cabin to take items out of the refrigerator from the side.

[0066] In some embodiments, the first heat exchanger 2 is configured to surround a portion of a plurality of first inner liner side surfaces 11, and / or, the first heat exchanger 2 is configured to surround the top surface 13 of the first inner liner, and / or, the first heat exchanger 2 is configured to surround the bottom surface 14 of the first inner liner.

[0067] In one specific embodiment, the first inner liner 1 includes three first inner liner sides 11, and the first heat exchanger 2 includes three first coils 23, each first coil 23 corresponding to one first inner liner side 11. This allows the first heat exchanger 2 to be configured to surround the first inner liner sides 11, thereby providing circumferential cooling to the first inner liner 1 and improving cooling efficiency. Each first coil 23 is configured as a multi-segment, meandering coil 23 structure to increase the heat transfer area with the first inner liner sides 11.

[0068] It should be noted that the first coil 23 is configured to be installed only around the three sides 11 of the first inner liner, and the first coil 23 is not installed on the top surface 13 and the bottom surface 14 of the first inner liner, thereby reducing the space occupied by the first heat exchanger 2 in the height direction of the vehicle's passenger compartment.

[0069] In some embodiments, such as Figure 3 As shown, the first inner liner 1 includes a first inner liner 151 and a second inner liner 152, wherein the second inner liner 152 is located inside the first inner liner 151, the first heat exchange element 2 surrounds the first inner liner 151, and the drawer 7 is located in the second inner liner 152. The first inner liner 151 is made of metal material to form a metal inner liner, and the second inner liner 152 is made of plastic material to form a plastic inner liner, which helps to improve the overall heat exchange efficiency and heat preservation performance of the first inner liner 1, and also facilitates the lightweight design of the refrigerator.

[0070] In some embodiments, the second inner liner 4 is configured to include a plurality of second inner liner side surfaces 41 and a second inner liner bottom surface 43, with the second inner liner bottom surface 43 connected to the plurality of second inner liner side surfaces 41. The top of the second inner liner 4 is also provided with a second inner liner opening 42, and the top of the second inner liner 4 is away from the first inner liner relative to the second inner liner bottom surface 43.

[0071] The refrigerator also includes a lid, which is movably connected to the second inner liner opening 42 of the second inner liner 4 so as to open or close the second inner liner opening 42.

[0072] In some embodiments, the second heat exchanger 5 is configured to surround at least a portion of a plurality of second inner liner side surfaces 41, and / or the second heat exchanger 5 is configured to surround the bottom surface 43 of the second inner liner.

[0073] In one specific embodiment, the second inner liner 4 includes four second inner liner sides 41, and the second coil 53 of the second heat exchanger 5 includes four sections of second coil 53, each section of second coil 53 corresponding to one second inner liner side 41. This allows the first heat exchanger 2 to be configured to surround the second inner liner sides 41, thereby providing circumferential cooling to the second inner liner 4 and improving cooling efficiency. Each section of second coil 53 is configured as a multi-segment, meandering coil structure to increase the heat transfer area with the second inner liner sides 41.

[0074] It should be noted that the second coil 53 is configured to be installed only around the four sides 41 of the second inner liner, and the second coil 53 is not installed on the bottom surface 43 of the second inner liner, thereby reducing the space occupied by the second heat exchanger 5 in the height direction of the vehicle's passenger compartment.

[0075] In some embodiments, such as Figure 4 As shown, the second inner liner 4 includes a third inner liner 441 and a fourth inner liner 442, wherein the fourth inner liner 442 is located inside the third inner liner 441, the second heat exchange element 5 surrounds the third inner liner 441, and the second storage space is located in the fourth inner liner 442. The third inner liner 441 is made of metal to form a metal inner liner, and the fourth inner liner 442 is made of plastic to form a plastic inner liner, which helps to improve the overall heat exchange efficiency and insulation performance of the second inner liner 4, and also facilitates the lightweight design of the refrigerator.
