[0038] In the description of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0039] The following description, with reference to Figures 1-6, describes a vehicle refrigerator 100 according to an embodiment of the present disclosure. By providing a heat exchange component 20, the vehicle refrigerator 100 can realize functions such as refrigeration, freezing, heating, and heat preservation.

[0040] As shown in Figures 1-4, a vehicle refrigerator 100 according to an embodiment of the present disclosure includes: an inner liner 10, a heat exchange component 20, and an air duct assembly 30. The inner liner 10 has a storage cavity 101 for providing space for users to store items. The inner liner 10 also has an air outlet 102 and an air inlet 103, both of which are connected to the storage cavity 101.

[0041] The heat exchange component 20 is disposed on the inner liner 10 and connected to the inner liner 10. The heat exchange component 20 can exchange heat with the inner liner 10 so that the heat of the heat exchange component 20 can be transferred to the inner liner 10. The heat exchange component 20 can be connected to one side plate 11 of the inner liner 10, or simultaneously connected to multiple side plates 11 of the inner liner 10, so as to increase the connection area between the two and improve the heat exchange efficiency between the heat exchange component 20 and the inner liner 10, thereby improving the efficiency of the vehicle refrigerator 100.

[0042] The air duct assembly 30 includes an air duct housing 31 and a fan 32. The fan 32 is disposed inside the air duct housing 31. The air duct housing 31 defines an air duct 311. The air duct housing 31 is connected to the storage cavity 101 so that the air duct 311 communicates with the storage cavity 101 through the air outlet 102 and the air inlet 103.

[0043] The inner liner 10 includes multiple side panels 11 and multiple air inlets 103. The multiple air inlets 103 are located on different side panels 11 of the inner liner 10, so that the air accelerated by the fan 32 can be introduced into the storage cavity 101 through the multiple air inlets 103.

[0044] In other words, within the air duct 311, the air accelerated by the fan 32 is introduced into the storage cavity 101 through the air inlet 103. The air comes into contact with the side panel 11 and undergoes 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, 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.

[0045] According to the embodiments of the present disclosure, the vehicle refrigerator 100, by designing multiple air inlets 103, can improve the uniformity and efficiency of airflow inside the storage cavity 101. 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 regulated. In addition, multiple air inlets 103 can accelerate the air circulation speed, so that the temperature can reach the set value more quickly, thereby reducing the cooling or heating operation time, realizing the 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 conservation and environmental protection.

[0046] In addition, the use of a single fan 32 can reduce energy consumption and effectively reduce the noise of the vehicle refrigerator 100 during use, thereby improving the comfort of the passenger compartment; and the overall structure is simple, reducing processing and manufacturing costs.

[0047] In some examples, the inner liner 10 is also surrounded by an outer shell (not shown in the figure). The outer shell is used to support and protect the internal structure of the vehicle refrigerator 100. The inner liner 10 can be installed inside the outer shell. The outer shell protects the inner liner 10, the heat exchange component 20 and the air duct assembly 30, ensuring the reliability of the vehicle refrigerator 100.

[0048] As shown in Figure 4, in some embodiments, the number of air inlets 103 is the same as the number of side panels 11, with multiple air inlets 103 corresponding one-to-one with multiple side panels 11. This not only improves the efficiency of air circulation but also optimizes the airflow field, allowing cold or hot air to form 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 setting multiple air inlets 103 on multiple side panels 11, the airflow field can be optimized, the fan speed 32 can be reduced, and the noise of the vehicle refrigerator 100 during operation can be effectively reduced, providing users with a quieter operating environment.

[0049] In some examples, the heat exchange component 20 includes multiple heat exchange sections, the number of which is the same as the number of side plates 11. Each heat exchange section corresponds to a single side plate 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.

[0050] In each side plate 11, the projections of the air inlet 103 and the corresponding heat exchange section on the side plate 11 can be staggered, thereby facilitating the connection between the air duct shell 31 and the inner liner 10.

[0051] As shown in Figure 3, in some embodiments, the air duct 31 includes a main air duct 3111 and a plurality of auxiliary air ducts 3112. 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. The plurality of auxiliary air ducts 3112 are arranged at intervals. One end of the plurality of auxiliary air ducts 3112 is connected to the other end of the main air duct 3111. The other end of the plurality of auxiliary air ducts 3112 is connected to a plurality of air inlets 103 in a corresponding manner.

[0052] By setting the main air duct 3111, the installation and arrangement of the fan 32 are 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, facilitate the timely flow of air to the corresponding air inlet 103, and at the same time help reduce noise and optimize air distribution.

[0053] As shown in Figure 3, in some examples, at least a portion of the cross-sectional area of ​​the main air duct 3111 gradually increases along the direction close to the auxiliary air duct 3112. That is, the cross-sectional area of ​​the main air duct 3111 can gradually increase in the direction close to the auxiliary air duct 3112. By changing the cross-sectional area, the pressure distribution in the air duct can be controlled more effectively, ensuring the uniformity and stability of airflow.

[0054] As shown in Figure 3, in some examples, the fan 32 is arranged inside the main air duct 3111. By placing the fan 32 inside the main air duct 3111, the airflow efficiency of multiple auxiliary air ducts 3112 can be improved by setting up one fan, saving costs and space. In addition, by placing the fan 32 inside the main air duct 3111 and combining it with the design of the air duct, the airflow entering multiple air inlets 103 through multiple auxiliary air ducts 3112 can be kept constant, which helps to improve the temperature uniformity inside the storage cavity 101.

[0055] As shown in Figure 4, in some embodiments, the inner liner 10 also includes a first cover 12, which is connected to one end of a plurality of side plates 11. An air outlet 102 is provided on the first cover 12, thereby the air outlet 102 and the air inlet 101 are provided at different positions in the inner liner 10, which is beneficial to increase the distance between the air inlet 103 and the air outlet 102, optimize air flow, and improve air handling efficiency.

[0056] As shown in Figure 4, in some embodiments, multiple air inlets 103 are located on the side plate 11 at a position away from the first cover 12, which can effectively increase the distance between the air inlets 103 and the air outlets 102, which is beneficial to optimize air flow, improve air handling efficiency, and reduce noise.

[0057] For example, multiple air inlets 103 are arranged near the bottom of the inner liner 10, and air outlets 102 are 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 the items can be quickly cooled and heated no matter where they are placed. At the same time, the design of the top air outlet 102 increases the convective heat exchange area between the air and the inner liner 10 wall and the items. On the one hand, the cold or heat of the inner liner 10 wall 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 and the air in the storage cavity 101, reducing the time for cooling or heating.

[0058] As shown in Figures 2 and 4, in some embodiments, the first cover 12 is located at one end of a plurality of side plates 11 in a first direction F1, and the positions of a plurality of air inlets 103 in the first direction F1 correspond. For example, the first direction F1 is the up-down direction, the first cover 12 is located at the upper end of the side plate 11, the air inlets 103 are located at the lower part of the side plate 11, and the plurality of air inlets 103 are located at the same height, that is, the upper edge of the air inlets 103 is roughly flush, and the lower edge of the air inlets 103 can also be roughly flush. Thus, the plurality of air inlets 103 have a certain correspondence, which is beneficial to balance the airflow and allows air to enter the storage cavity 101 of the inner liner 10 from the same height position, thereby improving the temperature uniformity of each position in the storage cavity 101.

[0059] As shown in Figure 4, in some embodiments, the inner liner 10 further includes a second cover 13, which is connected to the end of a plurality of side plates 11 away from the first cover 12. The second cover 13, the first cover 12, and the plurality of side plates 11 define a storage cavity 101 that is open on one side in a second direction F2. The second direction F2 can be a front-back direction. The inner liner 10 is connected to a storage cover that can close the storage cavity 101.

[0060] The second cover 13, the first cover 12, and the multiple side plates 11 together define the storage cavity 101. The inner liner 10 is connected to 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.

[0061] As shown in Figure 1, in some embodiments, the air duct housing 31 includes a volute housing 3101 and an air guide housing 3102. The volute housing 3101 is disposed on the first cover 12, and the fan 32 is disposed inside the volute housing 3101.

[0062] The air guide shell 3102 is located on the outside of the side plate 11. The air guide shell 3102 includes a first shell section 31021, a second shell section 31022, and a third shell section 31023. The air inlet 103 includes three sections. 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 with the air inlet 103. Here, it needs to be sealed with the outer periphery of the air inlet 102. The second shell section 31022 and the third shell section 31023 are respectively located opposite the first shell section 31021. On both sides, the second shell section 31022 can be connected to the middle of one side of the first shell section 31021, and the third shell section 31023 can be connected to the middle of the other side of the first shell section 31021. The second shell section 31022 and the third shell section 31023 extend towards the other two air inlets 103 respectively. The second shell section 31022 extends to the outside of the other side plate 11, and the third shell section 31023 extends to the outside of the other side plate 11. The second shell section 31022 can be connected to the corresponding air inlet 103, and the third shell section 31023 can be connected to the corresponding air inlet 103.

[0063] Thus, the three air inlets 103 have corresponding air intake ducts, and the side walls of the second shell section 31022 and the third shell section 31023 both have smooth arc surfaces, which allows air to be quickly guided to the multiple air inlets 103. Through the above structural design, not only can the efficiency of air circulation be improved, but the air flow field can also be optimized, so that the air in the vehicle refrigerator 100 forms a more reasonable convection, thereby improving the cooling and heating performance of the vehicle refrigerator 100.

[0064] In some embodiments, the fan 32 is a centrifugal fan. Centrifugal fans have high air pressure and strong resistance, making them suitable for use in the small space of a vehicle refrigerator.

[0065] 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 of the heat exchange component 20 on the outside of the inner liner 10, the space occupied by the heat exchange component 20 inside the inner liner 10 can be avoided, thus 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, which can reduce assembly steps, reduce production costs, and allow the heat exchange component 20 to fit better with the outside of the inner liner 10, so as to connect the two and increase the contact area between the two, thereby improving the heat exchange efficiency and thus improving the efficiency of the vehicle refrigerator 100.

[0066] As shown in Figures 1 and 2, in some embodiments, the air duct assembly 30 is located on the outside of the inner liner 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 liner 10. This avoids the air duct assembly 30 occupying the space inside the inner liner 10, reducing the storage space of the vehicle refrigerator 100. At the same time, it reduces the interference of the air duct assembly 30 with the heat exchange component 20, allowing the heat exchange component 20 to fit better with the inner liner 10 and improve heat exchange efficiency.

[0067] As shown in Figure 1, in some embodiments, the heat exchange component 20 includes a first heat exchange component 21 and a second heat exchange component 22. The first heat exchange component 21 is connected to the inner liner 10, and the second heat exchange component 22 is located outside the first heat exchange component 21 and is connected to the first heat exchange component 21. One of the first heat exchange component 21 and the second heat exchange component 22 is a cooling component, and the other of the first heat exchange component 21 and the second heat exchange component 22 is a heating component. Thus, the first heat exchange component 21 can directly transfer its heat to the side plate 11 of the inner liner 10, and the second heat exchange component 22 can transfer heat to the first heat exchange component 21, and then to the side plate 11 of the inner liner 10. Of course, a part of the second heat exchange component 22 can also be directly connected to the inner liner 10, thereby improving the heat transfer efficiency.

[0068] In some examples, the first heat exchanger 21 is an evaporator and the second heat exchanger 22 is a heating element.

[0069] The first heat exchanger 21 can be fixed to the outer wall of the inner liner 10 by brazing, thereby forming an integral part with the inner liner 10, which can improve the efficiency of heat transfer from the first heat exchanger 21 to the inner liner 10.

[0070] The heating element can be bonded to the first heat exchanger 21. The heating element can be an electric heating film. The heating element can be wrapped around the outer side of the inner liner 10 and the first heat exchanger 21. The electric heating film is lightweight and thin, making it easy to install.

[0071] When the vehicle refrigerator 100 starts the cooling mode, the refrigerant flows through the evaporator and evaporates to cool the interior. The temperature of the side panel 11 of the inner liner 10 drops to the set temperature in a short time. At the same time, the fan 32 starts to work, forming airflow in the storage cavity 101, as shown in Figure 4. Most areas of the entire storage cavity 101 form an upward airflow. Through the convection heat exchange between the air and the side panel of the inner liner 10, the air in the storage cavity 101 is rapidly cooled. It is drawn into the air duct from the air outlet 102 and delivered to the three air inlets 103 by the fan, as shown in Figure 5. Accelerated by the fan 32, the cold air is blown towards the items near the air inlets 103 at a relatively fast speed, thereby rapidly cooling the items.

[0072] When the car refrigerator 100 starts the heating mode, the heating element on the outer wall of the inner liner 10 starts to work, and the temperature of the side panel 11 of the inner liner 10 rises to the set temperature in a short time. At the same time, the fan 32 starts to work, forming an airflow circulation similar to that in the cooling mode in the storage cavity 101. Finally, the hot air is accelerated by the fan 32 and blown towards the items near the air inlet 103 at a relatively fast speed, thereby rapidly heating the items.

[0073] When the car refrigerator 100 is working in cooling and heating modes, the airflow fills the entire storage cavity 101, so that the cold and heat of the entire inner liner 10 can be transferred to the items in the storage cavity 101 as quickly as possible. At the same time, the airflow speed on the surface of the inner liner 11 is uniform, so that the items placed in different areas of the storage cavity 101 cool down and heat up at the same rate, avoiding the occurrence of large temperature differences.

[0074] 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 of the storage cavity 101. This simplifies the structure of the heat exchange component 20 and facilitates the installation of the heat exchange component 20 on the inner liner 10.

[0075] In some other embodiments, the heat exchange component 20 is a semiconductor refrigeration chip, that is, the refrigeration and heating are performed by the semiconductor refrigeration chip, so that the heat exchange component 20 can be used to both cool and heat 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 liner 10.

[0076] As shown in Figure 7, the vehicle 200 according to an embodiment of the present disclosure is provided with a vehicle refrigerator 100 according to an embodiment of the present disclosure. By providing the vehicle refrigerator 100, the operating time of the refrigeration or heating equipment is reduced, rapid refrigeration and heating are achieved, work efficiency is improved, energy consumption is reduced, noise is reduced, and the comfort of the passenger compartment is improved.

[0077] As shown in Figure 7, in some embodiments, the vehicle 200 also includes a compressor 40, and the heat exchange component 20 of the vehicle refrigerator 100 can be connected to the compressor 40.

[0078] In some examples, the compressor 40 can provide a heat source to the vehicle refrigerator 100 to realize the cooling or heating functions of the vehicle refrigerator 100. The compressor 40 can produce refrigerant.
