Description

[0002] With the development of economy and the improvement of material living standards, more and more vehicles are equipped with vehicle-mounted refrigerators to meet the growing needs of passengers. The current vehicle-mounted refrigerator is usually arranged in the armrest box between the main driver's seat and the co-driver's seat. Since the volume of the armrest box is small, the installation space of the vehicle-mounted refrigerator is small, and thus the volume of the vehicle-mounted refrigerator is also small. In order to adapt to the small installation space and the small volume of the vehicle-mounted refrigerator, the current vehicle-mounted refrigerator is usually set as a direct-cooling box using a blow-through evaporator to directly cool. Although the direct-cooling vehicle-mounted refrigerator can achieve the cooling effect, its heat conduction efficiency is low and the cooling effect is poor, and thus the above problems need to be solved.

[0034] Please refer to Figure 1Embodiments of the present application provide a vehicle-mounted refrigerator 100 and a transport vehicle 200 configured with the vehicle-mounted refrigerator 100. The transport vehicle 200 refers to a tool for transporting passengers and goods, such as a vehicle, a manned aircraft, a ship, etc. In the present application, the transport vehicle 200 can be a vehicle, which refers to a traffic tool driven or towed by a power device for people to ride or for transporting goods, including but not limited to a small car, a sport utility vehicle (SUV), a multi-purpose vehicle (MPV), a bus, a truck, etc. Hereinafter, the transport vehicle 200 is taken as a vehicle for example.

[0035] In the present embodiment, the transport vehicle 200 can include a body 20 and the vehicle-mounted refrigerator 100. Specifically, in the case where the transport vehicle 200 is a vehicle, the body 20 can be a vehicle body for fixing and accommodating the vehicle-mounted refrigerator 100. The body 20 can be provided with a driver's cabin 201 for accommodating a driver, so that the driver can control the transport vehicle 200 through a control system (for example, a center console, a driving system, a braking system, etc.) arranged in the driver's cabin 201. The vehicle-mounted refrigerator 100 is arranged in the driver's cabin 201, so that the driver or a passenger can conveniently take the goods placed in the vehicle-mounted refrigerator 100.

[0036] Please refer to Figures 2 to 5 Embodiments of the present application provide a vehicle-mounted refrigerator 100 for cooling the goods (for example, beverages, food, etc.) placed in the interior thereof. The vehicle-mounted refrigerator 100 includes a shell module 10, a refrigeration module 11 and a fan 12.

[0037] The shell module 10 is used to form the overall frame and appearance of the vehicle refrigerator 100. The shell module 10 includes a box body 101 and a shell 102, both of which are at least partial structures of the shell module 10. The box body 101 is provided with a refrigeration cavity 103, which is a cavity for accommodating objects placed inside the vehicle refrigerator 100. The air inside the refrigeration cavity 103 is at a low temperature, for example, -18℃ to 10℃ (herein only as a specific example, not a limitation on the temperature range of the refrigeration cavity 103). The refrigeration cavity 103 can have a refrigeration effect on the objects inside the vehicle refrigerator 100. As a specific example, in the present embodiment, the box body 101 is generally in the structure of a cuboid. In other embodiments, the box body 101 can also be in the structure of a cube, a cylinder, or any other shape. The shell 102 is arranged outside the box body 101, and part of the structure of the shell 102 is arranged separately from the box body 101 to form an installation cavity 104 together with the box body 101, and the installation cavity 104 is spaced apart from the refrigeration cavity 103. It should be noted that "the installation cavity 104 is spaced apart from the refrigeration cavity 103" means that there is a partition between the installation cavity 104 and the refrigeration cavity 103 for separating the two, although the installation cavity 104 and the refrigeration cavity 103 are separated by the partition, the installation cavity 104 and the refrigeration cavity 103 can be in communication. For example, the partition can be a side wall of the box body 101 provided with an opening. Since the refrigeration cavity 103 is located inside the box body 101, and the installation cavity 104 is located between the box body 101 and the shell 102, the installation cavity 104 is located outside the box body 101, and the installation cavity 104 and the refrigeration cavity 103 are spaced apart, but the opening on the side wall (partition) of the box body 101 can communicate the installation cavity 104 and the refrigeration cavity 103.

[0038] The refrigeration module 11 is the main component of the vehicle refrigerator 100 for refrigeration. Please refer to Figure 6 , the refrigeration module 11 includes an evaporation assembly 111, a compression condensation assembly 114, and a pipeline assembly 113 connected together. The evaporation assembly 111 is arranged in the installation cavity 104, and the evaporation assembly 111 is provided with a connection node 112 (see Figure 5), the evaporating assembly 111 is connected to the pipeline assembly 113 through the connecting node 112. It should be noted that the connecting node 112 is at least part of the structure of the evaporating assembly 111 for connecting with the pipeline assembly 113, and the connecting node 112 and the pipeline assembly 113 can be connected through any connection mode such as welding connection, threaded connection or sleeve connection. The pipeline assembly 113 is a component for connecting the evaporating assembly 111 and the compression-condensing assembly 114, and the pipeline assembly 113 includes several pipelines. The pipeline assembly 113 is connected between the evaporating assembly 111 and the compression-condensing assembly 114 to form an evaporative cooling circulation loop, so that the coolant circulates in the interior of the refrigeration module 11. The coolant can be refrigerant R134a, refrigerant R404A, refrigerant R410A, refrigerant R407C, etc. The connecting node 112 is located outside the refrigeration cavity 103.

[0039] The fan 12 is arranged in the mounting cavity 104, and the box body 101 is provided with a ventilation opening 105 for communicating the mounting cavity 104 with the refrigeration cavity 103. The fan 12 is used to disturb the air flow in the mounting cavity 104, so that the air with low temperature in the mounting cavity 104 enters the refrigeration cavity 103 through the ventilation opening 105 to achieve the refrigeration effect. Specifically, the ventilation opening 105 can have any shape such as a long strip shape, a round hole shape, a square hole shape, etc. The number of the ventilation openings 105 can be one or more, which is not limited in the embodiment.

[0040] Through the above arrangement, since the vehicle-mounted refrigerator 100 is provided with the refrigeration module 11 and the fan, when the vehicle-mounted refrigerator 100 works, the coolant circulates in the evaporating assembly 111, the pipeline assembly 113 and the compression-condensing assembly 114 to form an evaporative cooling circulation loop, so that the evaporating assembly 111 in the mounting cavity 104 continuously absorbs heat to generate air with low temperature in the mounting cavity 104. Then the fan 12 can blow the air with low temperature in the mounting cavity 104 into the refrigeration cavity 103 through the ventilation opening 105, thereby continuously providing the refrigeration cavity 103 with air with low temperature to enable the refrigeration cavity 103 to stably refrigerate the articles in the interior, thus improving the heat exchange efficiency and refrigeration effect of the vehicle-mounted refrigerator 100. Since the shell module 10 of the vehicle-mounted refrigerator 100 includes the connected box body 101 and shell 102, the box body 101 is provided with the refrigeration cavity 103, and the mounting cavity 104 is formed between the box body 101 and the shell 102. The evaporating assembly 111 is arranged in the mounting cavity 104, and the connecting node 112 of the evaporating assembly 111 is arranged outside the refrigeration cavity 103. Therefore, when the vehicle-mounted refrigerator 100 is assembled, the evaporating assembly 111 and the connecting node 112 thereof do not need to be arranged in the refrigeration cavity 103 with small space, thereby facilitating the staff to install the evaporating assembly 111 and facilitating the staff to connect the evaporating assembly 111 and the pipeline assembly 113 through the connecting node 112 to form the evaporative cooling circulation loop between the evaporating assembly 111 and the compression-condensing assembly 114.

[0041] In summary, the vehicle-mounted refrigerator 100 realizes air-cooled refrigeration by setting the refrigeration module 11 and the fan 12, and improves the refrigeration efficiency. Moreover, by setting the box body 101 and the shell 102, the installation position of the evaporating assembly 111 and the connecting node 112 thereof is set outside the refrigeration cavity 103 with small space, so that the evaporating assembly 111 can be conveniently installed by the staff, and the evaporating assembly 111 is connected with other components through the connecting node 112. Therefore, the vehicle-mounted refrigerator 100 not only facilitates the staff to assemble, but also has the beneficial effects of high refrigeration efficiency and good refrigeration effect.

[0042] Please refer to Figure 2 , Figure 4 and Figure 10 In some embodiments, the shell 102 is provided with a containing groove 1021 recessed away from the box body 101. Specifically, the containing groove 1021 is arranged on the surface of the shell 102 facing the box body 101. When the shell 102 is connected to the box body 101, the containing groove 1021 is located at the end of the box body 101 and forms the installation cavity 104 with the box body 101, and the evaporating assembly 111 is contained in the containing groove 1021. Through the above arrangement, when the shell 102 is in a separated state from the box body 101, the evaporating assembly 111 is directly exposed on the surface of the box body 101, and there is a large enough operation space around the evaporating assembly 111, so that the staff can conveniently install the evaporating assembly 111 and connect the evaporating assembly 111 with other structures. When the shell 102 is in a connected state with the box body 101, the containing groove 1021 forms the installation cavity 104 with the box body 101, and the evaporating assembly 111 is located in the installation cavity 104, so that the shell 102 surrounds and covers the evaporating assembly 111, not only protecting the evaporating assembly 111, but also providing a structural basis for the vehicle-mounted refrigerator 100 to realize air-cooled refrigeration.

[0043] Please refer to Figures 4 to 7In some embodiments, the compression-condensation assembly 114 comprises a condenser 1142 and a compressor 1141. Due to the large volume of the condenser 1142 and the compressor 1141, the condenser 1142 and the compressor 1141 can be arranged outside the housing module 10 to reduce the volume of the housing module 10. The connection nodes 112 are provided in plurality, and the plurality of connection nodes 112 comprises a first connection node 1121 and a second connection node 1122. The pipeline assembly 113 comprises a first pipeline 1131, a second pipeline 1132 and a third pipeline 1133. The first pipeline 1131 is connected between the first connection node 1121 and the compressor 1141 to realize the connection between the evaporation assembly 111 and the compressor 1141. The second pipeline 1132 is connected between the second connection node 1122 and the condenser 1142 to realize the connection between the evaporation assembly 111 and the condenser 1142. The third pipeline 1133 is connected between the condenser 1142 and the compressor 1141 to realize the connection between the two. The housing module 10 is provided with a plurality of accommodating through holes (not shown in the figure), and the pipeline assembly 113 is arranged in the accommodating through holes to realize the connection between the evaporation assembly 111 and the compression-condensation assembly 114 arranged outside the housing module 10. The plurality of accommodating through holes can be all arranged on the box body 101, or all arranged on the housing 102, or arranged on both the box body 101 and the housing 102, which is not limited.

[0044] Through the above arrangement, the pipeline assembly 113 realizes the mutual communication among the evaporation assembly 111, the condenser 1142 and the compressor 1141, so that the coolant can circulate and flow among the evaporation assembly 111, the condenser 1142 and the compressor 1141, and change the phase to absorb the heat of the air in the installation cavity 104.

[0045] In some embodiments, the connection structure between the connection nodes 112 and the pipeline assembly 113 is a welding connection. The welding connection can realize the stable and reliable connection between the connection nodes 112 and the pipeline assembly 113, and since the connection nodes 112 are located outside the refrigeration cavity 103, there is a large enough space around the connection nodes 112 for the workers to weld the connection nodes 112 and the pipeline assembly 113.

[0046] Please refer to Figure 2 , Figure 4 and Figure 7In some embodiments, the evaporation assembly 111 comprises fins 1111 and an evaporation pipe 1112 penetrating the fins 1111. The fins 1111 can be arranged in plurality and fixedly connected to the cabinet 101, for example, by welding or fasteners such as screws. The evaporation pipe 1112 can be an evaporation coil pipe, and the evaporation pipe 1112 can penetrate multiple fins 1111 at the same time. The fins 1111 and the evaporation pipe 1112 can be connected by welding or integrally formed. The connecting node 112 is arranged at the end of the evaporation pipe 1112 and located in the installation cavity 104.

[0047] Since multiple fins 1111 are arranged, when the liquid refrigerant enters the evaporation pipe 1112 and absorbs heat in the installation cavity 104 to become gaseous, the multiple fins 1111 can increase the heat exchange area to improve the heat exchange efficiency of the evaporation assembly 111, thereby improving the cooling effect of the coolant on the air in the installation cavity 104. Moreover, since the connecting node 112 is located in the installation cavity 104, the worker can first connect the fins 1111 to the outer surface of the cabinet 101 before connecting the cabinet 101 to the shell 102, then weld the evaporation pipe 1112 to the pipeline assembly 113 through the connecting node 112, and finally connect the shell 102 to the cabinet 101 to form the installation cavity 104, so that the evaporation assembly 111 is located in the installation cavity 104 to cool the air in the installation cavity 104. Through the above arrangement, the problems of small installation space of the evaporation assembly 111 and inconvenience in connecting the evaporation assembly 111 with other structures (such as the pipeline assembly 113) can be effectively solved. Moreover, the use of the evaporation assembly 111 with fins 1111 in combination with the fan 12 to achieve air-cooled refrigeration of the vehicle-mounted refrigerator 100 has higher refrigeration efficiency and better refrigeration effect compared with the traditional direct-cooling refrigeration mode of foamed evaporation pipe.

[0048] Please refer to Figure 2 , Figure 4 , Figures 8 to 10In some embodiments, the cabinet 101 comprises a shell 1011 and an inner container 1012. The refrigeration cavity 103 is arranged inside the inner container 1012, and the shell 1011 is arranged outside the inner container 1012. The shell 1011 is the outermost shell structure of the cabinet 101, and the first opening 1013 is arranged on the shell 1011. The inner container 1012 is the main structure of the vehicle-mounted refrigerator 100 for containing objects, and the second opening 1014 is arranged on the inner container 1012 for the user to take objects from the refrigeration cavity 103. The inner container 1012 is in sliding connection with the shell 1011, so that the inner container 1012 can be slid from the inside of the shell 102 through the first opening 1013, so that the second opening 1014 is exposed outside the shell 102, so that the user can take the objects in the inner container 1012 from the second opening 1014. As a specific example, in the present embodiment, the shell 1011 and the inner container 1012 are both substantially cuboid. In other embodiments, the shell 1011 and the inner container 1012 can also be any shape such as a square, a cylinder, etc., and the shapes of the shell 1011 and the inner container 1012 can be the same or different, which is not limited. In some embodiments, the shell 1011 and the inner container 1012 can be arranged apart, and a heat preservation material can be arranged therebetween to improve the refrigeration effect of the vehicle-mounted refrigerator 100. The evaporation pipe 1112 of the evaporation assembly 111 extends outside the mounting cavity 104, and the connection node 112 is located between the inner container 1012 and the shell 1011. Specifically, the end of the evaporation pipe 1112 extends between the side wall of the inner container 1012 and the side wall of the shell 1011, and the connection node 112 is located between the side wall of the inner container 1012 and the side wall of the shell 1011.

[0049] Through the above arrangement, since the connection node 112 is located between the side wall of the inner container 1012 and the side wall of the shell 1011, before the shell 1011 of the cabinet 101 is connected to the inner container 1012, the connection node 112 is exposed to the outside of the inner container 1012, so there is a large enough space around the connection node 112 for the worker to weld it to the pipeline assembly 113. After the connection between the connection node 112 and the pipeline assembly 113 is completed, the worker then arranges the shell 1011 outside the inner container 1012 and connects it to the inner container 1012, so that the connection node 112 is located between the shell 1011 and the inner container 1012 of the cabinet 101. This can reduce the volume of the mounting cavity 104, and in turn reduce the overall volume of the vehicle-mounted refrigerator 100.

[0050] It should be noted that the setting position of the connection node 112 can be adaptively adjusted according to the actual situation of the installation space of the vehicle-mounted refrigerator 100. In actual production, the end of the evaporation pipe 1112 of the evaporation assembly 111 can be extended to a position with a larger space according to the structure parameters of the installation space in advance, and then the specific position of the connection node 112 can be adjusted to provide a larger operation space for the staff when connecting the connection node 112 with the pipeline assembly 113.

[0051] Please refer to Figure 4 and Figure 5 In some embodiments, the fan 12 has an air outlet side, that is, the side of the fan 12 blowing air outward. The air outlet side is arranged towards the air vent 105, so that the air in the installation cavity 104 is blown to the refrigeration cavity 103 through the air vent 105. The box body 101 is also provided with a return air vent 106 for communicating the installation cavity 104 with the refrigeration cavity 103. The return air vent 106 is arranged in a spaced manner with the air vent 105, and the return air vent 106 is used for discharging the air in the refrigeration cavity 103 to the installation cavity 104 through the return air vent 106. Specifically, the return air vent 106 can have any shape such as a long strip shape, a round hole shape, a square hole shape, etc. The number of the return air vent 106 can be one or more, which is not limited in the embodiment.

[0052] Through the above arrangement, under the action of the fan 12, the air with a lower temperature in the installation cavity 104 can enter the refrigeration cavity 103 through the air vent 105, and the air with a higher temperature in the refrigeration cavity 103 after completing heat exchange with the object can return to the installation cavity 104 through the return air vent 106, so as to be cooled and refrigerated by the evaporation assembly 111. The air is continuously circulated between the installation cavity 104 and the refrigeration cavity 103, and finally the refrigeration effect on the object in the refrigeration cavity 103 is realized.

[0053] Please refer to Figure 4 and Figure 5 In some embodiments, when the vehicle-mounted refrigerator 100 is in a use state, the return air vent 106 and the air vent 105 are arranged in a parallel manner along the gravity direction, and the return air vent 106 is located below the air vent 105. It is not difficult to understand that, due to the refrigeration effect of the evaporation assembly 111, the air temperature in the installation cavity 104 will be lower than the air temperature in the refrigeration cavity 103. Therefore, when the air with a lower temperature in the installation cavity 104 enters the refrigeration cavity 103 through the air vent 105 under the action of the fan 12, the air with a lower temperature will sink, and then “force” the air with a higher temperature in the refrigeration cavity 103 to be discharged to the installation cavity 104 through the return air vent 106, so as to smoothly realize the circulation of the air in the refrigeration cavity 103 and the installation cavity 104.

[0054] Please refer to Figure 2 and Figure 7In some embodiments, the vehicle-mounted refrigerator 100 further comprises a connecting mechanism 13 arranged between the box body 101 and the shell 102. The connecting mechanism is used to achieve detachable connection of the box body 101 and the shell 102. As a specific example, in the present embodiment, the connecting mechanism 13 comprises a threaded fastener (not shown in the figure), which can be a bolt, a self-tapping screw, etc. The threaded fastener is arranged in one of the box body 101 and the shell 102 and is threadedly connected to the other one of the box body 101 and the shell 102. Specifically, the threaded fastener can be arranged in the shell 102 and threadedly connected to the box body 101, or the threaded fastener can be arranged in the box body 101 and threadedly connected to the shell 102. Through the above arrangement, the worker can conveniently connect and disassemble the shell 102 and the box body 101, thereby facilitating the worker to overhaul the structure (such as the evaporation assembly 111) between the shell 102 and the box body 101.

[0055] In other embodiments, the connecting mechanism 13 can comprise a clamping piece and a matching piece (both not shown in the figure) that are clamped and matched. The clamping piece is arranged in one of the box body 101 and the shell 102, and the matching piece is arranged in the other one of the box body 101 and the shell 102. The clamping piece can be a clamping jaw, a clamping hook, etc., and the matching piece can be a clamping groove, a clamping buckle, etc. that are adapted to the clamping piece. The clamping piece and the matching piece can be detachably clamped and matched to achieve connection and disassembly of the shell 102 and the box body 101.

[0056] In other embodiments, the shell 102 and the box body 101 can also be fixedly connected in a non-detachable manner. For example, the shell 102 and the box body 101 can be fixedly connected by ultrasonic welding, hot riveting, friction welding, etc. Through the above arrangement, the shell 102 and the box body 101 can have better integrity and stability, and there is no need to additionally arrange a sealing structure to ensure the sealed environment of the mounting cavity 104.

[0057] Please refer to Figures 7 to 10 In some embodiments, the vehicle-mounted refrigerator 100 further comprises a sealing mechanism 14 arranged between the box body 101 and the shell 102 and surrounding the outer periphery of the accommodating groove 1021 to form a sealing structure between the box body 101 and the shell 102. Through the above arrangement, due to the presence of the sealing mechanism 14, when the shell 102 and the box body 101 are connected, the air located in the mounting cavity 104 (i.e. between the accommodating groove 1021 and the box body 101) cannot be discharged outward from the connection between the shell 102 and the box body 101, thus ensuring that the air with a lower temperature in the mounting cavity 104 can only enter the refrigeration cavity 103 from the air inlet under the drive of the fan 12, thereby ensuring the realization of the air-cooled refrigeration mode.

[0058] In some embodiments, the sealing mechanism 14 comprises at least one set of sealing assembly, which comprises a sealing ring groove 141 and a sealing ring (not shown in the figure). Both the sealing ring groove 141 and the sealing ring are annular structures. The sealing ring groove 141 surrounds the outer periphery of the accommodating groove 1021, and is arranged on the surface of the cabinet 101 facing the shell 102 or on the surface of the shell 102 facing the cabinet 101. The sealing ring is embedded in the sealing ring groove 141 and is clamped by the cabinet 101 and the shell 102 together.

[0059] Through the above arrangement, the sealing ring is clamped by the cabinet 101 and the shell 102 together to form a sealing structure. Since the sealing ring is arranged in the sealing ring groove 141, which surrounds the outer periphery of the accommodating groove 1021, the sealing structure formed by the sealing ring also surrounds the outer periphery of the accommodating groove 1021, thereby avoiding the low-temperature air between the accommodating groove 1021 and the cabinet 101 from being discharged outwardly from between the shell 102 and the cabinet 101. When multiple sets of sealing assemblies are arranged, the sealing ring grooves 141 of the multiple sets of sealing assemblies can be arranged concentrically and spaced apart, which can improve the sealing effect of the sealing mechanism 14.

[0060] In some embodiments, the sealing ring groove 141 is a ring-shaped labyrinth groove. The sealing ring is an annular structure made of a heat-insulating material with elasticity, such as EVA (Ethylene Vinyl Acetate) sponge, foamed PVC (Polyvinyl Chloride), polyurethane, silica gel, rubber, EPS (Expandable Polystyrene) foam, etc. Through the above arrangement, the sealing effect of the sealing mechanism 14 can be further improved, thereby improving the refrigeration effect of the vehicle-mounted refrigerator 100. Moreover, the sealing ring itself also has a heat-insulating effect, which can improve the cooling efficiency and cooling effect of the evaporating assembly 111 on the air in the installation cavity 104.

[0061] In summary, the embodiments of the present application provide a vehicle-mounted refrigerator 100, which realizes air-cooled refrigeration by itself and improves the refrigeration efficiency by arranging the refrigeration module 11 and the fan 12. Moreover, by arranging the cabinet 101 and the shell 102, the installation position of the evaporating assembly 111 and the connecting node 112 thereof is arranged outside the refrigeration cavity 103 with a small space, so that the evaporating assembly 111 can be conveniently installed by the staff, and the evaporating assembly 111 is connected to other components through the connecting node 112. Therefore, the vehicle-mounted refrigerator 100 is not only convenient for the staff to assemble, but also has the beneficial effects of high refrigeration efficiency and good refrigeration effect.
