DETAILED DESCRIPTION

[0044] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0045] Reference below Figure 1-Figure 18 A vehicle refrigerator according to an embodiment of the utility model is described, and the utility model also provides a vehicle.

[0046] Reference Figure 1-5 As shown, the vehicle-mounted refrigerator of the embodiment of the utility model includes: an inner tank 10 and a pipeline assembly 20.

[0047] The pipe assembly 20 is arranged on the outside of the inner pot 10. Food can be placed in the inner pot 10. The pipe assembly 20 is used for cooling or heating. The heat of the pipe assembly 20 can be exchanged with the inner pot 10, so that the temperature of the food in the inner pot 10 increases or decreases, thereby achieving the effect of heating or preserving the food.

[0048] The pipeline assembly 20 includes: at least one first refrigerant tube 21 and at least one second refrigerant tube 22, at least one first refrigerant tube 21 and at least one second refrigerant tube 22 are arranged in sequence in a first direction, a cooling refrigerant or a heating refrigerant flows in the first refrigerant tube 21, and a heating refrigerant or a cooling refrigerant flows in the second refrigerant tube 22. Specifically, at least one first refrigerant tube 21 and at least one second refrigerant tube 22 are arranged in sequence in a first direction on the outer wall of the inner liner 10, at least one first refrigerant tube 21 and at least one second refrigerant tube 22 are closely attached to the inner liner 10, and the heat of the cooling refrigerant or the heating refrigerant can be exchanged with the inner liner 10, so that the temperature of the inner liner 10 drops or rises, thereby realizing the preservation or heating of the food inside.

[0049] Among them, the first direction can be the up and down direction, and by arranging at intervals in sequence on the first direction of the outer wall of the inner tank 10 at least one first refrigerant tube 21 and at least one second refrigerant tube 22, the first refrigerant tube 21 and the second refrigerant tube 22 can be distributed over a large range and evenly on the inner tank 10 of the vehicle refrigerator to the greatest extent, thereby achieving better cooling or heating effects.

[0050] Specifically, at least one first refrigerant tube 21 can be a heating harmonica tube, and a heating refrigerant flows in the first refrigerant tube 21. The heating refrigerant condenses and releases heat, and the temperature of the inner tank 10 rises, which can achieve the function of heating food. The first refrigerant tube 21 is close to the inner tank 10, and the inner tank 10 has a better heat absorption effect on the heating refrigerant, and the efficiency of heating using the heating refrigerant is higher, so the heating effect of the vehicle refrigerator is improved.

[0051] At least one second refrigerant tube 22 can be a refrigeration harmonica tube. A refrigeration refrigerant flows in the second refrigerant tube 22. The refrigeration refrigerant evaporates and absorbs heat, and the temperature of the inner tank 10 drops, which can achieve the function of preserving or freezing food.

[0052] Moreover, phase change material 32 is evenly distributed around the first refrigerant tube 21 and the second refrigerant tube 22. The phase change material 32 is filled in the phase change material side plate 31, and can absorb excess cold or heat in the first refrigerant tube 21 or the second refrigerant tube 22. When the cooling refrigerant or the heating refrigerant completes cooling or heating, the phase change material 32 can release the previously stored cold or heat to the inner tank 10, thereby prolonging its cooling or heating effect.

[0053] Therefore, by providing at least one first refrigerant pipe 21 and utilizing the heating refrigerant in the first refrigerant pipe 21 to exchange heat with the inner tank 10, the heat absorption effect of the inner tank 10 can be improved, and the heating effect of the vehicle refrigerator can be improved.

The second header assembly 24 is an outlet header assembly, that is, the refrigeration refrigerant or the heating refrigerant can flow out from the second header assembly 24. Since at least one first refrigerant tube 21 and at least one second refrigerant tube 22 are connected to the first header assembly 23 and the second header or at least one second refrigerant tube 22, they exchange heat with the inner liner 10 and then flow out from the second header assembly 24, thereby realizing the cycle of refrigeration or heating of the vehicle refrigerator.

[0061] Specifically, a plurality of through holes 34 are also provided on the heating outlet manifold 241, and the plurality of through holes 34 are spaced apart in the first direction, and the spacing between the plurality of through holes 34 is the same as the spacing between at least one first refrigerant tube 21, and the positions of the plurality of through holes 34 and at least one first refrigerant tube 21 correspond one to one, and the other end of the first refrigerant tube 21 is connected to the heating outlet manifold 241 through the through hole 34, and the refrigeration refrigerant flows into the refrigeration outlet manifold 242 through the through hole 34 after heat exchange with the inner tank 10.

[0062] Similarly, the refrigeration outlet manifold 242 is also provided with a plurality of through holes 34, the spacing between the plurality of through holes 34 is the same as the spacing between at least one second refrigerant tube 22, and the positions of the plurality of through holes 34 and at least one second refrigerant tube 22 correspond one to one, the other end of the second refrigerant tube 22 is connected to the refrigeration outlet manifold 242 through the through hole 34, and the refrigeration refrigerant flows from the refrigeration outlet manifold 242 to the second refrigerant tube 22 through the through hole 34.

[0063] The through hole 34 may be disposed on the side or the rear of the cooling inlet header 232 and the heating inlet header 231 .

[0064] Reference Figure 6-9 As shown, the pipeline assembly 20 also includes: a first joint 25, on which a heating liquid inlet 251 and a cooling liquid inlet 252 are formed, the heating liquid inlet 251 is connected to the heating inlet manifold 231, the cooling liquid inlet 252 is connected to the cooling inlet manifold 232, and the first joint 25 is fixed to the first manifold assembly 23. Among them, a first flow channel 2311 is provided on the heating inlet manifold 231, and a second flow channel 2321 is provided on the cooling inlet manifold 232, and the first flow channel 2311 and the second flow channel 2321 can allow the refrigerant to pass. The first joint 25 is provided with a heating liquid inlet 251 and a cooling liquid inlet 252, the heating liquid inlet 251 is connected to the first flow channel 2311, and the cooling liquid inlet 252 is connected to the second flow channel 2321.

[0065] Furthermore, the pipe assembly 20 further includes: a second joint 26, on which a heating liquid outlet 261 and a cooling liquid outlet 262 are formed, the heating liquid outlet 261 is communicated with the heating outlet header 241, the cooling liquid outlet 262 is communicated with the cooling outlet header 242, and the second joint 26 is fixed to the second header assembly 24.

[0066] The first joint 25 and the first current collecting assembly 23 may be connected by welding, and the second joint 26 and the second current collecting assembly 24 may also be connected by welding. The first joint 25 and the second joint 26 may be connected to a refrigerant pipeline, and a solenoid valve is connected to the refrigerant pipeline, which may control the flow direction of the cooling refrigerant and the heating refrigerant.

[0067] In some vehicle refrigerators, the heat exchanger is in parallel with the battery pack heat exchanger. When the battery pack turns on the cooling mode and the vehicle refrigerator needs to turn on the heating mode, the vehicle refrigerator is fed with cooling refrigerant, which conflicts with the heating demand of the vehicle refrigerator. By integrating the heating inlet manifold 231 and the cooling inlet manifold 232, the heating outlet manifold 241 and the cooling outlet manifold 242 into one, and controlling the flow direction of the cooling refrigerant and the heating refrigerant through an electromagnetic valve, the conflict between the refrigerant demand of the battery pack and the vehicle refrigerator can be avoided.

[0068] When the vehicle refrigerator and the battery pack are in cooling mode at the same time, the solenoid valve of the refrigerant pipeline inserted into the cooling liquid inlet 252 and the solenoid valve of the refrigerant pipeline inserted into the cooling liquid outlet 262 are opened. At the same time, the solenoid valve of the refrigerant pipeline inserted into the heating liquid inlet 251 and the solenoid valve of the refrigerant pipeline inserted into the heating liquid outlet 261 are closed. At this time, the vehicle refrigerator heat exchanger and the battery pack heat exchanger are in parallel, and the cooling refrigerant flows into the vehicle refrigerator and the battery pack heat exchanger respectively.

[0069] Specifically, the refrigeration refrigerant flows into the refrigeration inlet manifold 232 through the refrigeration liquid inlet 252 and the second flow channel 2321, and then flows into the second refrigerant tube 22 through the multiple through holes 34 of the refrigeration inlet manifold 232. The second refrigerant tube 22 is close to the inner tank 10, and can absorb the heat of the inner tank 10, so that the temperature of the inner tank 10 is reduced, thereby achieving the refrigeration effect of the vehicle refrigerator.

[0070] At the same time, the phase-changing material located between the inner tank 10 and the phase-changing material side plate can absorb and store excess cold in the refrigerant. After releasing the cold, the refrigerant flows into the refrigeration outlet manifold 242 through multiple through holes 34 from the second refrigerant pipe 22, and flows out through the fourth flow channel 2421 and the refrigeration liquid outlet 262.

[0071] When the battery pack is turned on in cooling mode and the vehicle refrigerator is turned on in heating mode, the solenoid valve on the refrigerant pipeline inserted into the heating liquid inlet 251 and the solenoid valve on the refrigerant pipeline inserted into the heating liquid outlet 261 are opened. At the same time, the solenoid valve on the refrigerant pipeline inserted into the cooling liquid inlet 252 and the solenoid valve on the refrigerant pipeline inserted into the cooling liquid outlet 262 are closed. At this time, the cooling refrigerant flows through the battery pack heat exchanger, and the heating refrigerant flows into the vehicle refrigerator.

[0072] Specifically, the heating refrigerant flows into the heating inlet manifold 231 through the heating liquid inlet 251 and the first flow channel 2311, and flows into the first refrigerant tube 21 through the multiple through holes 34 of the heating inlet manifold 231. The first refrigerant tube 21 is close to the inner tank 10, releases the heat stored in the inner tank 10, thereby increasing the temperature of the inner tank 10, achieving the effect of a car refrigerator.

[0073] At the same time, the phase-changing material located between the inner tank 10 and the phase-changing material side plate can absorb and store excess heat in the heating refrigerant. After releasing the heat, the heating refrigerant flows from the first refrigerant pipe 21 through multiple through holes 34 into the heating outlet manifold 241, and flows out through the third flow channel 2411 and the heating liquid outlet 261.

[0074] Reference Figure 6-9 As shown, the first joint 25 and the second joint 26 are both inclined relative to the second direction, and the second direction and the first direction are perpendicular to each other. Specifically, the second direction can be a horizontal direction, and the first joint 25 and the second joint 26 form an angle of 60° with the horizontal direction, which can facilitate the management of the first current collecting assembly 23 and the second current collecting assembly 24, and also facilitate the connection between the first joint 25 and the second joint 26 and the pipeline.

[0075] Reference Figure 6-9 As shown, the first manifold assembly 23 includes: a first tube body 233 and a plurality of first end caps 234, and the plurality of first end caps 234 are arranged at both ends of the heating inlet manifold 231 and the cooling inlet manifold 232. That is, the first tube body 233 includes the heating inlet manifold 231 and the cooling inlet manifold 232, and the first end caps 234 are arranged above and below the first tube body 233, and the first end caps 234 seal the first tube body 233 to prevent the cooling refrigerant and the heating refrigerant from flowing out from the top or bottom, which affects the cooling and heating effects of the vehicle refrigerator.

[0076] And, the second manifold assembly 24 includes: a second tube body 243 and a plurality of second end caps 244, and the plurality of second end caps 244 are arranged at both ends of the heating outlet manifold 241 and the cooling outlet manifold 242.

[0077] The connection method between the first end cover 234 and the first tube body 233 and the connection method between the second end cover 244 and the second tube body 243 can both be welding.

[0078] Reference Figure 2 , Fig.10 and Fig.11 As shown, in some embodiments, a first refrigerant tube 21 and a second refrigerant tube 22 are arranged in sequence in the first direction. As shown in the figure, in other embodiments, at least two first refrigerant tubes 21 and at least two second refrigerant tubes 22 are arranged in sequence in the first direction.

[0079] That is to say, the first refrigerant tube 21 and the second refrigerant tube 22 may be arranged in an interval manner, that is, the first refrigerant tube 21—the second refrigerant tube 22—the first refrigerant tube 21—the second refrigerant tube 22, or two first refrigerant tubes 21 and two second refrigerant tubes 22 may be arranged in an interval manner, that is, the first refrigerant tube 21—the first refrigerant tube 21—the second refrigerant tube 22—the second refrigerant tube 22—the first refrigerant tube 21—the first refrigerant tube 21—the second refrigerant tube 22—the second refrigerant tube 22 are arranged in sequence, or three first refrigerant tubes 21 and three second refrigerant tubes 22 may be arranged in an interval manner, that is, the first refrigerant tube 21—the first refrigerant tube 21—the first refrigerant tube 21—the second refrigerant tube 22—the second refrigerant tube 22—the first refrigerant tube 21—the first refrigerant tube 21—the second refrigerant tube 22—the second refrigerant tube 22—the first refrigerant tube 21—the first refrigerant tube 21—the second refrigerant tube 22—the second refrigerant tube 22 are arranged in sequence.

[0080] Reference Figure 12-18 As shown, in some embodiments, the pipeline assembly 20 also includes: a third joint 27 and a fourth joint 28, the third joint 27 is arranged on the first current collecting assembly 23, the fourth joint 28 is arranged on the second current collecting assembly 24, and in the first direction, the third joint 27 is higher than the fourth joint 28, and the pipeline assembly 20 also includes: a fifth joint 30 and a sixth joint 29, the fifth joint 30 is arranged on the first current collecting assembly 23, the sixth joint 29 is arranged on the second current collecting assembly 24, and in the first direction, the fifth joint 30 is higher than the sixth joint 29.

[0081] Specifically, a third refrigerant pipe 33 may also be provided on the outside of the inner tank 10. The third refrigerant pipe 33 is connected between the first collecting assembly 23 and the second collecting assembly 24. The cooling refrigerant and the heating refrigerant can flow in the third refrigerant pipe 33. The third refrigerant pipe 33 may be a harmonica tube. The third refrigerant pipe 33 is adhered to the inner tank 10 by a thermally conductive double-sided tape or thermally conductive silicone grease attached to the inner tank 10 of the vehicle refrigerator.

[0082] Similarly, the first collecting assembly 23 includes a heating inlet collecting pipe 231 and a cooling inlet collecting pipe 232, and the second collecting assembly 24 includes a heating outlet collecting pipe 241 and a cooling outlet collecting pipe 242, wherein the first collecting assembly 23 is connected to the third joint 27 and the fifth joint 30, and the second collecting assembly 24 is connected to the fourth joint 28 and the sixth joint 29, and the third joint 27, the fourth joint 28, the fifth joint 30 and the sixth joint 29 are respectively connected to the refrigerant pipeline, and the third joint 27, the fourth joint 28, the fifth joint 30 and the sixth joint 29 are fastened and sealed with bolts to prevent the refrigeration or heating failure of the vehicle refrigerator.

[0083] When the vehicle refrigerator is in cooling mode, the refrigerant flows from the third joint 27 into the cooling inlet manifold 232, and then flows into the third refrigerant tube 33. The third refrigerant tube 33 is close to the inner tank 10, absorbs the heat of the inner tank 10, and thus reduces the temperature of the inner tank 10, thereby achieving the cooling effect of the vehicle refrigerator. After absorbing the heat, the refrigerant flows from the third refrigerant tube 33 into the cooling outlet manifold 242, and flows out through the fourth joint 28.

[0084] When the vehicle refrigerator is turned on in heating mode, the heating refrigerant flows from the fifth joint 30 of the right manifold assembly into the heating inlet manifold 231 and then into the third refrigerant tube 33.
