For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] Reference below Figure 1-Figure 6 The vehicle refrigerator 100 according to the embodiment of the present invention is described. By providing the heat exchange component 20 , the vehicle refrigerator 100 can realize functions such as refrigeration, freezing, heating, and heat preservation.

[0043] like Figure 1-Figure 4 As shown, a vehicle refrigerator 100 according to an embodiment of the present invention includes: an inner tank 10, a heat exchange component 20 and an air duct assembly 30, the inner tank 10 has a storage cavity 101, the storage cavity 101 is used to provide a space for users to store items, the inner tank 10 also has an air outlet 102 and an air inlet 103, and the air outlet 102 and the air inlet 103 are both connected to the storage cavity 101.

[0044] The heat exchange component 20 is disposed on the inner tank 10, and the heat exchange component 20 is connected to the inner tank 10. The heat exchange component 20 can perform heat exchange with the inner tank 10 so that the heat of the heat exchange component 20 can be transferred to the inner tank 10; the heat exchange component 20 can be connected to a side plate 11 of the inner tank 10, or connected to multiple side plates 11 of the inner tank 10 at the same time to increase the connection area between the two, thereby improving the heat exchange efficiency between the heat exchange component 20 and the inner tank 10, and thereby improving the efficiency of the vehicle refrigerator 100.

[0045] The air duct assembly 30 includes an air duct shell 31 and a fan 32 . The fan 32 is disposed in the air duct shell 31 . The air duct shell 31 defines an air duct 311 . The air duct shell 31 is connected to the storage cavity 101 so that the air duct 311 is connected to the storage cavity 101 through the air outlet 102 and the air inlet 103 .

[0046] The inner liner 10 includes a plurality of side panels 11 , and the air inlets 103 include a plurality of air inlets 103 , which are located on different side panels 11 of the inner liner 10 , so that the air accelerated by the fan 32 is passed into the storage cavity 101 through the plurality of air inlets 103 .

[0047] That is to say, in the air duct 311, the air accelerated by the fan 32 enters the storage cavity 101 through the air inlet 103, and the air contacts the side panel 11 for heat exchange, thereby cooling or heating the air. The cooled air can cool the items in the storage cavity, and the heated air can heat the items in the storage cavity. The air continues to flow to the air outlet 102 and enters the air duct 311 through the air outlet 102. Thus, a relatively closed flow channel is formed as a whole, that is, the air is internally circulated, which reduces the probability of heat exchange with the outside air, thereby improving the heat exchange efficiency of the vehicle refrigerator 100.

[0048] According to the vehicle refrigerator 100 of the embodiment of the present invention, by designing multiple air inlets 103, the uniformity and efficiency of the air flow inside the storage cavity 101 can be improved. The multiple air inlets 103 can cover a wider area, reduce the existence of dead corners, and ensure that the temperature in each corner can be quickly adjusted; and the multiple air inlets 103 can speed up the air circulation speed, so that the temperature can reach the set value more quickly, thereby reducing the running time of cooling or heating, realizing rapid cooling and heating of the vehicle refrigerator 100, improving the working efficiency of the vehicle refrigerator 100, reducing energy consumption, and meeting the requirements of energy saving and environmental protection.

[0049] In addition, since a fan 32 is used, energy consumption can be reduced and the noise during use of the vehicle refrigerator 100 can be effectively reduced, thereby improving the comfort of the passenger compartment; and the overall structure is simple, reducing the processing and manufacturing costs.

[0050] In some examples, the inner tank 10 also has an outer shell (not shown in the figure) on the outside, and the outer shell is used to support and protect the internal structure of the vehicle refrigerator 100. The inner tank 10 can be installed in the outer shell, and the inner tank 10, the heat exchange component 20 and the air duct assembly 30 are protected by the outer shell to ensure the reliability of the vehicle refrigerator 100.

[0051] like Figure 4 As shown, in some embodiments, the number of air inlets 103 is the same as the number of side panels 11, and the multiple air inlets 103 correspond to the multiple side panels 11 one by one, thereby not only improving the efficiency of air circulation, but also optimizing the air flow field, so that cold air or hot air forms a more reasonable convection inside the vehicle refrigerator 100, avoiding local overheating or overcooling, thereby improving the cooling and heating performance of the vehicle refrigerator 100; in addition, by arranging multiple air inlets 103 on multiple side panels 11, the air flow field can be optimized, the speed of the fan 32 can be reduced, and the noise during the operation of the vehicle refrigerator 100 is effectively reduced, providing users with a quieter use environment.

[0052] In some examples, the heat exchange component 20 includes multiple heat exchange sections, the number of heat exchange sections is the same as the number of side plates 11, the multiple heat exchange sections correspond one-to-one to the multiple side plates 11, and the multiple heat exchange sections are interconnected with the corresponding side plates 11, thereby improving the heat exchange effect on each side plate 11.

[0053] Among them, on each side plate 11 , the air inlet 103 and the projection of the corresponding heat exchange part on the side plate 11 can be arranged in a staggered manner, so as to facilitate the connection between the air duct shell 31 and the inner tank 10 .

[0054] like Figure 3 As shown, in some embodiments, the air duct 31 includes a main air duct 3111 and multiple auxiliary air ducts 3112, and the fan 32 can be arranged in the main air duct 3111, one end of the main air duct 3111 is connected to the air outlet 102, and the multiple auxiliary air ducts 3112 are arranged at intervals, one end of the multiple auxiliary air ducts 3112 is connected to the other end of the main air duct 3111, and the other end of the multiple auxiliary air ducts 3112 is connected to the multiple air inlets 103 one by one.

[0055] By setting up the main air duct 3111, the installation and arrangement of the fan 32 is facilitated. By designing multiple auxiliary air ducts 3112, each air inlet 103 has an independent air duct, which can improve the efficiency of air flow and facilitate air to flow to the corresponding air inlet 103 in time. At the same time, it is beneficial to reduce noise and optimize air distribution.

[0056] like Figure 3 As shown, in some examples, the cross-sectional area of ​​at least a portion of the main air duct 3111 gradually increases along the direction approaching the auxiliary air duct 3112, that is, the cross-sectional area of ​​the main air duct 3111 can gradually increase in the direction approaching the auxiliary air duct 3112. By changing the cross-sectional area, the pressure distribution in the air duct can be more effectively controlled to ensure the uniformity and stability of the air flow.

[0057] like Figure 3 As shown, in some examples, the fan 32 is arranged in the main air duct 3111. By arranging the fan 32 in the main air duct 3111, the air flow efficiency of multiple auxiliary air ducts 3112 can be improved by arranging one fan, saving cost and space. In addition, by arranging the fan 32 in the main air duct 3111 and combining the design of the air duct, the air volume entering the multiple air inlets 103 through the multiple auxiliary air ducts 3112 can be made uniform, which is convenient for improving the temperature uniformity in the storage cavity 101.

[0058] like Figure 4As shown, in some embodiments, the inner liner 10 also includes a first cover body 12, which is connected to one end of the multiple side panels 11, and the air outlet 102 is arranged on the first cover body 12, so that the air outlet 102 and the air inlet 101 are arranged at different positions of the inner liner 10, which is conducive to increasing the distance between the air inlet 103 and the air outlet 102, optimizing air flow, and improving air treatment efficiency.

[0059] like Figure 4 As shown, in some embodiments, multiple air inlets 103 are arranged at a position of the side panel 11 away from the first cover body 12, thereby effectively increasing the distance between the air inlet 103 and the air outlet 102, which is beneficial to optimizing air flow, improving air processing efficiency, and reducing noise.

[0060] For example, multiple air inlets 103 are arranged near the bottom of the inner liner 10, and the air outlet 102 is located at the top. The multiple air inlets 103 at the bottom allow the air circulation in the storage cavity 101 to cover a wider area, so that no matter where the items are placed, they can be quickly cooled and heated. At the same time, the design of the top air outlet 102 increases the convection heat exchange area between the air and the wall of the inner liner 10 and the items. On the one hand, the cold or heat on the wall of the inner liner 10 can be quickly transferred to the air, so that the temperature in the storage cavity 101 can be quickly cooled or heated. On the other hand, it also speeds up the heat exchange efficiency between the items in the storage cavity 101 and the air, reducing the cooling or heating time.

[0061] like Figure 2 and Figure 4 As shown, in some embodiments, the first cover body 12 is located at one end of the multiple side panels 11 in the first direction F1, and the positions of the multiple air inlets 103 in the first direction F1 correspond. For example, the first direction F1 is the up and down direction, the first cover body 12 is located at the upper end of the side panel 11, the air inlet 103 is arranged at the lower part of the side panel 11, and the multiple air inlets 103 are located at the same height, that is, the upper edges of the air inlets 103 are roughly flush, and the lower edges of the air inlets 103 can also be roughly flush. Therefore, the multiple air inlets 103 have a certain correspondence, which is conducive to balancing the airflow, and can allow air to enter the storage cavity 101 of the inner liner 10 from the same height position, thereby improving the uniformity of temperature at each position in the storage cavity 101.

[0062] like Figure 4 As shown, in some embodiments, the inner liner 10 also includes a second cover body 13, which is connected to one end of the multiple side panels 11 away from the first cover body 12. The second cover body 13, the first cover body 12 and the multiple side panels 11 define a storage cavity 101 open on one side in a second direction F2. The second direction F2 can be a front-to-back direction. The inner liner 10 is connected to a storage cover that can close the storage cavity 101.

[0063] The second cover body 13, the first cover body 12 and the plurality of side panels 11 together define a storage cavity 101. The inner liner 10 is connected with a storage cover, which may be used to close the storage cavity 101 to protect the internal items and prevent external heat, dust or other contaminants from entering the storage cavity.

[0064] like Figure 1 As shown, in some embodiments, the air duct housing 31 includes a volute 3101 and an air guide housing 3102 , the volute 3101 is disposed on the first cover body 12 , and the fan 32 is disposed in the volute 3101 .

[0065] The air guide housing 3102 is arranged on the outside of the side plate 11. The air guide housing 3102 includes a first shell section 31021, a second shell section 31022 and a third shell section 31023. The air inlet 103 includes three. The first shell section 31021 covers the outside of a side plate 11. One end of the first shell section 31021 is connected to the volute 3101, and the other end extends to an air inlet 103 to connect to the air inlet 103. Here, it is necessary to cooperate with the outer periphery of the air inlet 102 in a sealed manner. The second shell section 31022 and the third shell section 31023 are respectively located on the opposite sides of the first shell section 31021. On both sides, the second shell segment 31022 can be connected to the middle of one side of the first shell segment 31021, and the third shell segment 31023 can be connected to the middle of the other side of the first shell segment 31021. The second shell segment 31022 and the third shell segment 31023 respectively extend toward the other two air inlets 103, the second shell segment 31022 extends to the outside of the other side plate 11, and the third shell segment 31023 extends to the outside of another side plate 11. The second shell segment 31022 can be connected to the corresponding air inlet 103, and the third shell segment 31023 can be connected to the corresponding air inlet 103.

[0066] Therefore, the three air inlets 103 have corresponding air inlet ducts, and the side walls of the second shell section 31022 and the third shell section 31023 have smooth curved surfaces, so that the air can be quickly guided to the multiple air inlets 103. Through the above-mentioned structural design, not only the efficiency of air circulation can be improved, but also the air flow field can be optimized, so that the air can form a more reasonable convection in the vehicle refrigerator 100, thereby improving the cooling and heating performance of the vehicle refrigerator 100.

[0067] In some embodiments, the fan 32 is a centrifugal fan, which has high wind pressure and strong resistance, and is suitable for use in a small space of a car refrigerator.

[0068] In some embodiments, the heat exchange component 20 is disposed on the outside of the inner liner 10. Specifically, the heat exchange component 20 is connected to the inner liner 10 to achieve heat exchange with the inner liner 10. By disposing the heat exchange component 20 on the outside of the inner liner 10, the heat exchange component 20 can be prevented from occupying the space inside the inner liner 10, thereby reducing the storage space of the vehicle refrigerator 100. The heat exchange component 20 can be integrally formed on the outside of the inner liner 10, thereby reducing the assembly steps and reducing the production cost. The heat exchange component 20 can also be better fitted to the outside of the inner liner 10 to facilitate connecting the two, and the contact area between the two can be increased, thereby improving the heat exchange efficiency, thereby improving the efficiency of the vehicle refrigerator 100.

[0069] like Figure 1 and Figure 2 As shown, in some embodiments, the air duct assembly 30 is arranged on the outside of the inner tank 10, and at least a portion of the air duct assembly 30 is located on the side of the heat exchange component 20 away from the inner tank 10. This can avoid the air duct assembly 30 occupying the space inside the inner tank 10, thereby reducing the storage space of the vehicle refrigerator 100, and at the same time reducing the interference of the air duct assembly 30 with the heat exchange component 20, so that the heat exchange component 20 can better fit with the inner tank 10, thereby improving the heat exchange efficiency.

[0070] like Figure 1 As shown, in some embodiments, the heat exchange component 20 includes a first heat exchange element 21 and a second heat exchange element 22, the first heat exchange element 21 is connected to the inner tank 10, the second heat exchange element 22 is arranged on the outside of the first heat exchange element 21, the second heat exchange element 22 is connected to the first heat exchange element 21, one of the first heat exchange element 21 and the second heat exchange element 22 is a refrigeration element, and the other of the first heat exchange element 21 and the second heat exchange element 22 is a heating element, so that the first heat exchange element 21 can transfer its heat directly to the side plate 11 of the inner tank 10, and the second heat exchange element 22 can transfer the heat to the first heat exchange element 21, and then transfer it to the side plate 11 of the inner tank 10. Of course, a part of the second heat exchange element 22 can also be directly connected to the inner tank 10, so as to improve the heat transfer efficiency.

[0071] In some examples, the first heat exchange element 21 is an evaporator, and the second heat exchange element 22 is a heating element.

[0072] The first heat exchanger 21 can be fixed on the outer wall of the inner tank 10 by brazing, so that the first heat exchanger 21 and the inner tank 10 form an integral part, which can improve the efficiency of heat transfer from the first heat exchanger 21 to the inner tank 10.

[0073] The heating element can be bonded to the first heat exchange element 21, and the heating element can be an electric heating film. The heating element can be wrapped around the outer side of the inner tank 10 and the first heat exchange element 21. The electric heating film is light in weight, thin in thickness, and easy to install.

[0074] When the vehicle refrigerator 100 starts the cooling mode, the refrigerant flowing through the evaporator evaporates and cools, and the temperature of the side plate 11 of the inner tank 10 drops to the set temperature in a short time. At the same time, the fan 32 starts to work, and air flow is formed in the storage cavity 101. The air flow condition is as follows: Figure 4 As shown; most areas in the entire storage cavity 101 form an air flow from bottom to top. Through the convection heat exchange between the air and the side panels of the liner 10, the air in the storage cavity 101 is quickly cooled down, sucked into the air duct from the air outlet 102, and delivered to the three air inlets 103 by the fan. The air flow is shown in Figure 5 As shown; through the acceleration of the fan 32, the cold air blows at a faster speed toward the items near the air inlet 103, thereby quickly cooling the items.

[0075] When the vehicle refrigerator 100 starts the heating mode, the heating element on the outer wall of the inner tank 10 starts to work, and the temperature of the side panel 11 of the inner tank 10 rises to the set temperature in a short time. At the same time, the fan 32 starts to work, and an air flow circulation similar to that in the cooling mode is formed in the storage cavity 101. Finally, the hot air is accelerated by the fan 32 and blows toward the objects near the air inlet 103 at a faster speed, thereby quickly heating up the objects.

[0076] When the vehicle refrigerator 100 is operating in cooling and heating modes, air flow fills the entire storage cavity 101, so that the cold and heat of the entire inner tank 10 can be transferred to the items in the storage cavity 101 at the fastest speed. At the same time, the wind speed on the surface of the inner tank 11 is uniform, so that the cooling and heating rates of the items placed in different areas of the storage cavity 101 are consistent, avoiding the occurrence of large temperature differences.

[0077] In other embodiments, the heat exchange component 20 is a heat exchanger, that is, only one heat exchange component 20 is used. The heat exchange component 20 is connected to the compressor 40. By switching the control valve, the heat exchanger can be used as both an evaporator and a condenser, so that it can be used for cooling and heating the storage cavity 101, thereby simplifying the structure of the heat exchange component 20 and facilitating the installation of the heat exchange component 20 on the inner tank 10.

[0078] In some other embodiments, the heat exchange component 20 is a semiconductor refrigeration plate, that is, cooling and heating are performed by using the semiconductor refrigeration plate, so that the heat exchange component 20 can be used for cooling the storage cavity 101, and can also be used for heating the storage cavity 101, thereby simplifying the structure of the heat exchange component 20 and facilitating the installation of the heat exchange component 20 on the inner tank 10.

[0079] like Figure 7As shown, a vehicle 200 according to an embodiment of the present invention is provided with a vehicle refrigerator 100 according to an embodiment of the present invention.
