Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a vehicle-mounted refrigerator and vehicle. Background Technology

[0002] Currently, in-vehicle refrigerators primarily rely on independent compressor systems for cooling. In these systems, the compressor compresses the refrigerant and circulates it within the system to achieve cooling. However, independent compressor systems are noisy, affecting driving comfort, and their complex structure and large space requirements reduce the utilization of the vehicle's interior space. To address these issues, some vehicles share a compressor with the overall vehicle cooling system. However, traditional in-vehicle refrigerators have insufficient heat exchange capacity, leading to frequent compressor start-stop cycles, increasing energy consumption and shortening the equipment's lifespan.

[0003] In addition, insulation material is usually filled between the outer shell and the internal layers of a car refrigerator for heat insulation. However, the insulation material may age after long-term use, resulting in a decrease in heat insulation performance and affecting the heat insulation effect. Some insulation materials will affect the environment during production and processing. In order to ensure the heat insulation effect, the insulation material is thick, which makes the overall volume and weight of the car refrigerator large.

[0004] Therefore, there is an urgent need to propose a vehicle-mounted refrigerator and vehicle to solve the above-mentioned technical problems. Utility Model Content

The cabinet contains a storage compartment and a vacuum chamber. The storage compartment is used to store food, and the vacuum chamber surrounds the storage compartment to form an insulation layer. Compared with existing technologies that fill the cabinet with insulation material, the vacuum almost eliminates heat conduction and convection, resulting in better insulation, extended insulation time, reduced material costs, and reduced weight. Furthermore, by integrating the refrigeration pipe assembly of the refrigeration module and the cold storage pipe assembly of the cold storage module within the vacuum chamber, the space of the vacuum chamber is fully utilized.

Furthermore, arranging the refrigeration pipe assembly around the storage compartment improves temperature uniformity, which is beneficial for enhancing food refrigeration.

[0030] By incorporating a cold storage module, the system absorbs and stores cold energy during refrigeration and releases it when the refrigeration module stops operating. This effectively extends the insulation time, reduces the frequency of compressor start-ups and shutdowns, thereby saving energy and extending the equipment's lifespan. Furthermore, arranging the cold storage module's cold storage pipes around the storage chamber ensures a more uniform temperature within the chamber when the module releases cold energy, which improves the refrigeration effect on food.

By employing the aforementioned vehicle-mounted refrigerator, the vehicle increases the utilization rate of interior space, reduces the start-stop frequency of the compressor, saves energy, and also reduces the complexity and assembly cost of the entire vehicle system.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0052] Example 1

[0053] This embodiment provides a vehicle-mounted refrigerator that shares a compressor with the vehicle while incorporating a cold storage module. This simplifies the structure, extends the insulation time, reduces the compressor's start-stop frequency, and thus saves energy. Furthermore, the refrigeration pipe assembly and the cold storage pipe assembly are integrated into a vacuum chamber, utilizing vacuum performance for insulation. This enhances the insulation effect while improving space utilization, thereby reducing the size of the vehicle-mounted refrigerator.

[0054] See Figure 1 and Figure 2 The vehicle-mounted refrigerator includes a cabinet 100, a refrigeration module 200, and a cold storage module 300.

[0055] The refrigerator features a storage compartment 110 within its housing 100 and a vacuum chamber 120 surrounding the storage compartment 110. The storage compartment 110 is used to store beverages, food, or medicine. The vacuum chamber 120 utilizes the insulating effect of a vacuum to form an insulation layer, virtually eliminating heat conduction and convection between the storage compartment 110 and the external environment. Compared to existing technologies that fill the housing with insulation material, this provides better insulation, extends the insulation time, saves material costs, and reduces the weight of the vehicle refrigerator. Furthermore, the vacuum process is non-toxic and safe, contributing to environmental protection.

[0056] See Figure 2 and Figure 3 The refrigeration module 200 includes a refrigeration pipe assembly 210, which is disposed within a vacuum chamber 120 and surrounds the outer perimeter of the storage compartment 110. The sealed environment within the vacuum chamber 120 reduces heat exchange between the refrigeration pipe assembly 210 and the external environment. Both the inlet and outlet of the refrigeration pipe assembly 210 are connected to the refrigerant circuit of the vehicle's air conditioning system. This means the refrigerant in the refrigeration pipe assembly 210 comes from the vehicle's air conditioning system, and the on-board refrigerator shares a compressor with the vehicle's air conditioning system. Compared to existing technologies that use independent compressors, this eliminates additional noise, improves driving comfort, simplifies the structure, and further reduces space requirements. Furthermore, surrounding the storage compartment 110 with the refrigeration pipe assembly 210 improves temperature uniformity within the storage compartment 110, which is beneficial for enhancing food refrigeration.

[0057] Optionally, in one possible embodiment, the inlet of the refrigeration pipe assembly 210 is connected to the outlet of the throttle valve of the vehicle's air conditioning system, and the outlet of the refrigeration pipe assembly 210 is connected to the inlet of the compressor of the vehicle's air conditioning system. This connection method makes the refrigeration pipe assembly 210 equivalent to being connected in parallel in the evaporator branch of the vehicle's air conditioning system, so that there is no need to configure a separate compressor for the refrigeration module 200. The refrigerant is driven by the existing compressor of the vehicle's air conditioning system, which simplifies the independent structure of the vehicle refrigerator and reduces the energy consumption and equipment cost of the whole vehicle.

[0058] See also Figure 2The cold storage module 300 includes a cold storage tube assembly 310, which is disposed within a vacuum chamber 120 and surrounds the outer wall of the storage chamber 110. The cold storage tube assembly 310 is filled with a refrigerant, and the sealed environment within the vacuum chamber 120 reduces heat exchange between the cold storage tube assembly 310 and the external environment. When the vehicle's air conditioning system is on, the refrigeration module 200 of the vehicle refrigerator cools while the refrigerant in the cold storage tube assembly 310 stores a portion of the cold energy. When the vehicle's air conditioning system is off or enters intermittent operation, the refrigeration module 200 stops cooling, and the refrigerant gradually releases its cold energy, providing a stable and continuous cooling effect to the storage chamber 110. Therefore, the cold storage module 300 effectively extends the insulation time, reduces the frequency of compressor start-stop, thereby saving energy and extending the equipment's service life. Furthermore, the cold storage tube group 310 of the cold storage module 300 is arranged around the storage chamber 110, so that the temperature in the storage chamber 110 is more uniform when the cold storage module 300 releases cold energy, which is beneficial to improving the refrigeration effect of food.

[0059] The vehicle-mounted refrigerator integrates the refrigeration pipe assembly 210 of the refrigeration module 200 and the cold storage pipe assembly 310 of the cold storage module 300 within the vacuum chamber 120, making full use of the space of the vacuum chamber 120. While ensuring the heat preservation effect, it reduces the overall volume of the vehicle-mounted refrigerator, enabling it to meet the assembly requirements of small spaces.

[0060] Further, see also Figures 1-3 In one possible embodiment, the box 100 includes an inner liner 130 and an outer shell 140. Both the inner liner 130 and the outer shell 140 have an opening at one end. The outer shell 140 is fitted over the inner liner 130, and the interior of the inner liner 130 is a storage chamber 110.

[0061] See also Figures 1-3 The inner liner 130 and the outer shell 140 form an annular opening, and an annular manifold 400 is used to seal the annular opening. The manifold 400, the inner liner 130 and the outer shell 140 form a vacuum cavity 120, thereby ensuring that a stable heat insulation layer is formed between the storage chamber 110 and the outside.

[0062] Optionally, in one possible embodiment, the housing 140 is provided with a vacuum valve 150, through which a vacuum chamber 120 is formed by evacuation.

[0063] Alternatively, in one possible embodiment, see Figure 4The manifold 400 is equipped with a refrigerant inlet 411 and a refrigerant outlet 421. Both the refrigerant inlet 411 and the refrigerant outlet 421 are connected to the refrigerant circuit of the vehicle's air conditioning system. The refrigerant pipe assembly 210 is connected to the manifold 400 and forms a refrigerant circulation loop with the manifold 400. During the circulation operation, the refrigerant of the vehicle's air conditioning system enters the manifold 400 through the refrigerant inlet 411 and is distributed to the refrigerant pipe assembly 210 to complete the heat exchange with the storage compartment 110. Then it returns to the manifold 400 and returns to the vehicle's air conditioning system through the refrigerant outlet 421 to achieve a continuous cooling cycle.

[0064] Further, alternatively, in one possible embodiment, see also: Figure 4 The refrigerant inlet 411 on the manifold 400 has a smaller orifice diameter than the refrigerant outlet 421. Since the refrigerant inlet 411 is connected after the outlet of the throttle valve, the refrigerant is in a throttling state from high pressure to low pressure. Therefore, the relatively small orifice diameter of the refrigerant inlet 411 is beneficial for controlling the flow rate into the refrigeration pipe assembly 210 and ensuring uniform distribution. The refrigerant outlet 421 is mainly used for the return flow of low-pressure gaseous refrigerant, and its relatively large orifice diameter reduces return flow resistance.

[0065] Alternatively, in one possible embodiment, see [link to previous document]. Figure 4 The manifold 400 is also provided with a refrigerant inlet 441 and a refrigerant outlet 451. The refrigerant inlet 441 is used to connect with the outlet of the refrigerant supply equipment, and the refrigerant outlet 451 is used to connect with the inlet of the refrigerant supply equipment. The refrigerant pipe group 310 is connected to the manifold 400 and forms a refrigerant circulation loop with the manifold 400.

[0066] Understandably, through the above structure, the manifold 400 not only serves as a seal, but also enables the refrigerant and the cold storage agent to form independent circulation loops, thereby achieving a combination of rapid cooling and cold storage insulation.

[0067] Alternatively, in one possible embodiment, see Figure 5The manifold 400 includes a first refrigerant manifold 410 connected to the refrigerant inlet 411, a second refrigerant manifold 420 connected to the refrigerant outlet 421, and several first connecting cavities 430. The refrigerant pipe assembly 210 includes multiple refrigerant pipes 211, with each pair of refrigerant pipes 211 sharing one first connecting cavity 430. The multiple refrigerant pipes 211 are connected end-to-end through several first connecting cavities 430 to form a refrigerant flow path. The refrigerant pipes 211 located at both ends of the refrigerant flow path are connected to the first refrigerant manifold 410 and the second refrigerant manifold 420, respectively. The first connecting cavities 430 reverse the refrigerant flow direction between adjacent refrigerant pipes 211, causing the refrigerant to form multiple reciprocating flow paths around the outer wall of the inner liner 130, thereby extending the residence time of the fluid in the heat exchange zone and improving the heat exchange efficiency.

[0068] Alternatively, in one possible embodiment, see [link to previous document]. Figure 5 The manifold 400 also includes a first refrigerant manifold 440 connected to the refrigerant inlet 441, a second refrigerant manifold 450 connected to the refrigerant outlet 451, and several second connecting cavities 460. The refrigerant tube group 310 includes multiple refrigerant tubes 311, with each pair of refrigerant tubes 311 sharing one second connecting cavity 460. The multiple refrigerant tubes 311 are connected end-to-end through several second connecting cavities 460 to form a refrigerant flow path. The refrigerant tubes 311 located at both ends of the refrigerant flow path are connected to the first refrigerant manifold 440 and the second refrigerant manifold 450, respectively. The second connecting cavities 460 reverse the flow direction of the refrigerant between adjacent refrigerant tubes 311, causing the refrigerant to form a reciprocating flow path around the outer wall of the inner liner 130, thereby filling the refrigerant module 300 with refrigerant and improving the refrigeration effect of the refrigerant module 300.

[0069] Understandably, during the operation of the vehicle's air conditioning system, refrigerant enters the first refrigerant manifold 410 through refrigerant inlet 411, flows sequentially through multiple refrigerant pipes 211 and several first connecting chambers 430, enters the second refrigerant manifold 420, and exits from the refrigerant outlet 421, thus forming a heat exchange circuit on the outer wall of the inner liner 130. Similarly, cold storage refrigerant enters the first cold storage refrigerant manifold 440 through cold storage refrigerant inlet 441, flows sequentially through multiple cold storage refrigerants and several second connecting chambers 460, enters the second cold storage refrigerant manifold 450, and exits from the cold storage refrigerant outlet 451, thus forming a cold storage circuit on the outer wall of the inner liner 130. The cold storage refrigerant is initially charged through the cold storage refrigerant inlet 441 during the assembly of the vehicle refrigerator. After charging, the cold storage refrigerant inlet 441 and the cold storage refrigerant outlet 451 are sealed. During operation of the vehicle refrigerator, no recirculation charging is required, and the cold storage refrigerant circulation circuit is in a closed state.

[0070] Alternatively, in one possible embodiment, see Figure 2 and Figure 5The refrigeration pipe assembly 210 may include two refrigeration pipes 211. After the refrigerant enters the first refrigeration pipe 211 from the first refrigerant manifold 410, it enters the second refrigeration pipe 211 through the first connecting cavity 430, and then flows to the second refrigerant manifold 420 to realize the refrigeration cycle loop.

[0071] Optionally, in another possible embodiment, the refrigeration pipe assembly 210 may further include four refrigeration pipes 211 connected sequentially through three first connecting cavities 430; in other possible embodiments, the refrigeration pipe assembly 210 may further include six refrigeration pipes 211 connected sequentially through five first connecting cavities 430, so that the refrigerant flows in different directions multiple times on the outer wall of the storage chamber 110, increasing the heat exchange area and improving the cooling efficiency.

[0072] Alternatively, in one possible embodiment, the cold storage tube assembly 310 may adopt the same layout scheme of the refrigeration tubes 211 as the refrigeration tube assembly 210 in the above embodiment.

[0073] Alternatively, in one possible embodiment, see again Figure 2 The refrigeration pipe assembly 210 includes multiple refrigeration pipes 211, which are U-shaped and surround the opposite side walls and the end wall opposite the open end of the inner liner 130. The cold storage pipe assembly 310 includes multiple cold storage pipes 311, which are U-shaped and surround the opposite side walls and the end wall opposite the open end of the inner liner 130. Furthermore, the multiple refrigeration pipes 211 and the multiple cold storage pipes 311 are arranged side-by-side, which can improve the cold storage capacity of the cold storage refrigerant during the refrigerant refrigeration process.

[0074] Further optionally, in one possible embodiment, the refrigeration pipe assembly 210 includes a plurality of refrigeration pipes 211, which surround the three side walls of the inner liner 130 and the end wall opposite to the open end; the cold storage pipe assembly 310 includes a plurality of cold storage pipes 311, which also surround the three side walls of the inner liner 130 and the end wall opposite to the open end.

[0075] Alternatively, in one possible embodiment, see again Figure 4 The refrigerant inlet 411, refrigerant outlet 421, cold storage inlet 441, and cold storage outlet 451 are located on the same side of the manifold 400, which facilitates the layout and connection of pipelines, reduces cross-pipeline routing, improves the simplicity of the assembly process, and ensures the effectiveness and stability of the refrigerant and cold storage. At the same time, it reduces the size of the manifold 400 and the vehicle refrigerator on the opening surface, reducing the space occupied by the vehicle refrigerator inside the vehicle.

[0076] Alternatively, in one possible embodiment, see Figure 2 and Figure 6The refrigeration pipe 211 is a porous flat tube. The interior of the porous flat tube has multiple independent fluid channels 2111 along its length. Each fluid channel 2111 is spaced apart in the width direction and connects to the manifold 400 at its open end, so as to evenly distribute the flow from the manifold 400 to different channels. The flat surface of the porous flat tube is arranged parallel to the outer surface of the inner liner 130, thereby increasing the contact area with the inner liner 130 and improving heat exchange efficiency. The cold storage pipe 311 can also be the same porous flat tube as the refrigeration pipe 211.

[0077] Alternatively, in one possible embodiment, the porous flat tube is connected to the inner liner 130 by brazing or thermally conductive adhesive, thereby increasing the efficiency of heat transfer and improving the cooling effect.

[0078] Alternatively, in one possible embodiment, see [link to previous document]. Figures 1-2 The refrigerant inlet 411, refrigerant outlet 421, refrigerant inlet 441, and refrigerant outlet 451 are each equipped with a flange interface 471. Multiple connection ports are fixed together by a connecting plate 470. The outer casing 140 has through holes 141 corresponding to the flange interfaces 471. Each flange interface 471 passes through the corresponding through hole 141 and is sealed to the refrigerant inlet 411, refrigerant outlet 421, refrigerant inlet 441, and refrigerant outlet 451 respectively. The connecting plate 470 abuts against the outside of the outer casing 140. The connecting plate 470 integrates multiple flange interfaces 471 together, facilitating installation and disassembly.

[0079] Alternatively, in one possible embodiment, see Figure 1 and Figure 7 The vehicle refrigerator also includes a drawer assembly 500, which includes an end cover 510 and a storage box 520 connected to the end cover 510. The external dimensions of the storage box 520 match the internal space of the storage compartment 110, and the storage box 520 is slidably disposed within the storage compartment 110 to achieve a pull-out operation. When the storage box 520 is fully pushed into the storage compartment 110, the end cover 510 can seal the opening of the storage compartment 110 to prevent cold air loss.

[0080] Alternatively, in one possible embodiment, the sliding fit structure between the storage box 520 and the storage chamber 110 can be a slide rail provided on the inner wall of the storage chamber 110 and matching slide grooves on both sides of the storage box 520. In another possible embodiment, the sliding fit structure can also be a guide groove on the inner wall of the storage chamber 110 engaging with a protruding slider on the outer wall of the storage box 520. With the above sliding structure, the storage box 520 can move smoothly along the depth direction of the storage chamber 110, and can be easily pulled out or pushed in during use, improving operational convenience.

[0081] Alternatively, in one possible embodiment, see [link to previous document]. Figure 1 and Figure 7 An annular seal 560 is provided on the plate of the end cap 510 facing the storage box 520. When the drawer assembly 500 is in the closed state, the annular seal 560 fits against the outer edge of the opening of the cabinet 100 near the storage chamber 110, thereby blocking air leakage and reducing the loss of cold energy.

[0082] Alternatively, in one possible embodiment, see [link to previous document]. Figure 7 The storage box 520 has a heating film 530 at its bottom, which is attached to the bottom plate of the storage box 520. The heating film 530 is used to heat the storage box 520. The heating film 530 can be activated as needed to heat and keep the food placed inside the storage box 520 warm. With this configuration, the car refrigerator can both refrigerate and heat food, and users can switch between refrigeration and heating as needed, making it versatile and meeting various user needs.

[0083] It is worth noting that the heating film typically integrates a heating element, and heating is achieved by energizing the heating element. The structure and working principle of the heating film are existing technologies; therefore, its structure will not be described in detail further.

[0084] Alternatively, in one possible embodiment, see Figure 7 and Figure 8 The storage box 520 has a first ventilation hole 521 at the end away from the end cover 510, which forms an air circulation channel between the storage box 520 and the outside. The end cover 510 has a first mounting cavity 511, which communicates with the storage box 520. The side of the end cover 510 facing the storage box 520 has a mounting opening 512 and a second ventilation hole 513, both of which connect the storage box 520 and the first mounting cavity 511. A fan 540 is installed at the mounting opening 512. When the fan 540 operates, it drives airflow, allowing air to enter the storage box 520, pass through the first ventilation hole 521, and then exit through the second ventilation hole 513, thus forming a circulating airflow within the storage box 520 and improving the temperature uniformity within the storage box 520.

[0085] Optionally, in one possible embodiment, the fan 540 can be an axial fan to enhance forced convection inside the storage chamber 110, promote heat exchange, thereby further improving heat exchange efficiency and ensuring a more balanced refrigeration effect for food.

[0086] Alternatively, in one possible embodiment, see [link to previous document]. Figure 7The end cap 510 has a first magnetic connector 550 on its side wall. The first magnetic connector 550 is electrically connected to the fan 540. When the drawer assembly 500 is in the closed state, the first magnetic connector 550 can be attracted and electrically connected to the second magnetic connector on the vehicle. The second magnetic connector is electrically connected to the power supply unit of the vehicle and can supply power to the fan 540.

[0087] Alternatively, the first magnetic connector 550 can be electrically connected to the heating film 530, allowing the vehicle's battery or generator to power the heating film 530 for heating food. This configuration eliminates the need for an additional power source, reduces the number of components, and simplifies the structure.

[0088] Alternatively, in one possible embodiment, see [link to previous document]. Figure 8 The end cap 510 also has a second mounting cavity 514, which is filled with insulation material. The insulation material is used to reduce the loss of cold or heat inside the storage box 520, so as to extend the heat preservation time of the vehicle refrigerator.

[0089] Optionally, the second mounting cavity 514 can be located away from the drawer assembly 500 relative to the first mounting cavity 511, which provides better insulation.

[0090] Further, optionally, see also Figure 7 and Figure 8 The end cap 510 includes an annular sidewall 517, a first panel 515 sealing one end of the annular sidewall 517, a second panel 516 sealing the other end of the annular sidewall 517, and a partition 518 disposed within the annular sidewall 517. The first panel 515, the annular sidewall 517, and the partition 518 form a first mounting cavity 511, and the second panel 516, the annular sidewall 517, and the partition 518 form a second mounting cavity 514. This end cap 510 has a simple structure and is easy to manufacture and assemble.

[0091] It is understood that in this technical solution, the mounting port 512 and the second ventilation hole 513 are formed on the first panel 515, and the first magnetic connector 550 is disposed on the annular sidewall 517. Optionally, in a possible embodiment, see further... Figure 7 and Figure 8 A temperature sensor 570 is provided on the plate of the end cap 510 facing the storage box 520. The temperature sensor 570 is used to detect the temperature inside the storage box 520. The temperature sensor 570 can detect the temperature inside the storage box 520 in real time. When the temperature is higher than the set threshold, the fan 540 can be activated to accelerate air circulation; when the temperature is lower than the set threshold, or as needed, the heating film 530 can be activated to automatically adjust the refrigeration and heating temperatures, thereby realizing automatic temperature control.

[0092] It is worth noting that in the above-mentioned technical solution where the end cap 510 has a first panel 515, the temperature sensor 570 can be set on the first panel 515.

[0093] Alternatively, the first magnetic connector 550 can be electrically connected to the temperature sensor 570, so that the vehicle's power supply unit can not only power the fan 540, but also power the heating film 530 and the temperature sensor 570 at the same time, simplifying the circuit.

[0096] The vehicle's use of the aforementioned onboard refrigerator increases the utilization of interior space, reduces the compressor's start-stop frequency, saves energy, and also reduces the complexity and assembly cost of the entire vehicle system.
