Description

Technical Field

[0001] This utility model relates to the field of vehicle refrigerator technology, specifically to a single-compressor multi-refrigeration box vehicle refrigerator and vehicle. Background Technology

[0002] A car refrigerator is a portable refrigeration / freezing device specifically designed for vehicles. It is mainly used to store food, beverages, medicines, and other items while driving or in outdoor settings to meet users' needs for low-temperature preservation or refrigeration.

[0003] To refrigerate a large number of items, some vehicles are currently equipped with multiple onboard refrigerators, such as RVs and pharmaceutical transport vehicles. Each onboard refrigerator includes a compressor and a refrigerator compartment. This design has the following problems: 1. Installing multiple independent compressors is costly, and the power consumption of multiple compressors is high in the later stages of operation; 2. The total weight of multiple independent compressors is relatively large, and the vehicle's load weight directly affects the vehicle's fuel economy (for gasoline vehicles) or driving range (for new energy vehicles). 3. Multiple independent compressors may cause inconsistent temperatures inside the multiple car refrigerators due to performance differences. For example, one car refrigerator may be too cold, while another may not be cooling enough. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a single-compressor multi-refrigeration-box vehicle refrigerator and vehicle. Compared with the use of multiple compressors in existing vehicle refrigerators, it has lower manufacturing costs, lower power consumption during use, and lighter total weight, which can reduce the energy consumption of the vehicle; it can also save vehicle space and ensure consistent cooling intensity in multiple boxes.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a single-compressor multi-refrigeration box type vehicle refrigerator, including an outer shell, a refrigeration module and multiple boxes. The outer shell is provided with refrigerant pipelines, and the multiple boxes are detachably connected to the outer shell. The refrigeration module includes a compressor, a condenser and an evaporator connected end to end through refrigerant pipelines. The compressor and the condenser are detachably connected to the outer shell. The number of evaporators is equal to the number of boxes. The evaporators are installed in the boxes, and the multiple evaporators are connected in parallel.

[0006] Preferably, the outer casing is a detachable metal casing.

[0007] Preferably, the outer casing is detachably connected to a side plate, and the outer casing has a first window for the refrigerant pipeline to be led out.

[0008] Preferably, the side panel is provided in multiple pieces, and each side panel has at least one second window. Multiple boxes are located next to multiple second windows, and the box doors on the boxes correspond to the adjacent second windows.

[0009] Preferably, a heat dissipation mesh is installed on the side plate.

[0010] Preferably, a solenoid valve is installed on the refrigerant pipeline, the solenoid valve is located between the condenser and the evaporator, and the solenoid valve is an expansion valve.

[0011] Preferably, a fan for heat dissipation is installed next to the condenser.

[0012] Preferably, the refrigerant pipeline is made of flexible tubing.

[0013] This utility model also provides a vehicle, including the above-mentioned single-compressor multi-refrigeration box type vehicle refrigerator, wherein the vehicle has a compartment, and the single-compressor multi-refrigeration box type vehicle refrigerator is located in the compartment.

[0014] Preferably, the vehicle has a storage compartment located outside the passenger compartment, and refrigerant piping is arranged inside the vehicle. The compressor and condenser are detachably connected to the storage compartment, and the housing is detachably connected to the passenger compartment. The evaporator is installed inside the housing, and the compressor, condenser, and evaporator are connected end to end in sequence via refrigerant piping.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are as follows: Compared to the use of multiple compressors in existing car refrigerators, the single compressor in this application has lower manufacturing costs, lower power consumption during operation, and lighter overall weight, thus reducing vehicle energy consumption. It also saves vehicle space, as the single compressor can be centrally installed in unused areas of the vehicle (such as the chassis or a corner of the trunk), and multiple compartments can be flexibly arranged in the vehicle's cabin according to usage needs (such as the front armrest, next to the rear seats, or in the trunk partition, as shown in the figure). In addition, using a single compressor ensures consistent cooling intensity across multiple compartments, effectively solving the problem of inconsistent temperatures within multiple car refrigerators caused by performance differences among multiple compressors.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0021] This embodiment relates to a single-compressor, multi-refrigeration-box vehicle-mounted refrigerator, such as... Figure 1 and 3 As shown, it includes an outer shell 1, a refrigeration module 4, and multiple housings 2. Refrigerant pipes 3 are arranged inside the outer shell 1. Multiple housings 2 are detachably connected to the outer shell 1. The refrigeration module 4 includes a compressor 41, a condenser 42, and an evaporator connected end to end through the refrigerant pipes 3. Both the compressor 41 and the condenser 42 are detachably connected to the outer shell 1. The number of evaporators is equal to the number of housings 2. The evaporators are installed inside the housings 2 and are connected in parallel.

[0022] In this application, compressor 41 is taken as a model of secop BND45K compressor, with a power of 80 to 100 watts, a speed of 4000 to 4500 rpm, a displacement of about 2.0 cc, and a weight of 1.6 kg; the compressors currently equipped in car refrigerators have a power of 50 to 80 watts, a speed of 2000 to 2500 rpm, a displacement of 1.5-2.0 cc, and a weight of 1.6 kg.

[0023] The box 2 is a refrigerator. When there are two or more refrigerators in the vehicle, only one compressor 41 is needed. That is, a compressor 41 with a higher speed or higher power can be selected. In the existing vehicle refrigerators, the number of boxes 2 corresponds to the number of compressors 41. Obviously, the use of a single compressor 41 in this application is lower in cost, consumes less electricity, and is lighter in total weight than the use of multiple compressors 41 in the existing vehicle refrigerators, which can reduce the energy consumption of vehicle 6. It also saves vehicle space, as a single compressor 41 can be centrally installed in unused areas of the vehicle 6 (such as the chassis or a corner of the trunk), and multiple compartments 2 can be flexibly arranged within the vehicle 6's passenger compartment 62 according to usage requirements (such as the front armrest, next to the rear seats, or in the trunk partition, etc.). Figure 7 (As shown).

[0024] In addition, using a single compressor 41 can ensure that the cooling intensity in multiple cabinets 2 is consistent, effectively solving the problem of inconsistent temperatures in multiple vehicle refrigerators caused by the performance differences of multiple compressors 41.

[0025] like Figure 1 and 2 As shown, the outer casing 1 is a detachable metal casing, which makes it easy for users to disassemble and repair the components inside the outer casing 1. The metal casing, such as a stainless steel casing or an aluminum alloy casing, has high hardness and can better protect the internal components.

[0026] like Figure 2 As shown, a side panel 12 is detachably connected to the outer casing 1, and a first window 11 is provided on the outer casing 1 for the refrigerant pipe 3 to be led out. The first window 11 facilitates the arrangement of the refrigerant pipe 3 inside the vehicle. The side panel 12 can be removed from the outer casing 1, which facilitates the installation of the refrigeration module 4 and the housing 2 inside the outer casing 1, or the removal of the refrigeration module 4 and the housing 2 from the outer casing 1.

[0027] Furthermore, the side panel 12 is provided with multiple panels, each with at least one second window 121. Multiple boxes 2 are located next to the multiple second windows 121, and the boxes 2 have doors corresponding to the nearest second window 121. The boxes 2 can be opened from the second window 121, allowing occupants to put food into the boxes 2 for refrigeration or to remove refrigerated food from the boxes 2.

[0028] like Figure 2 As shown, a heat dissipation mesh 122 is installed on the side plate 12. The heat dissipation mesh 122 facilitates the dissipation of heat inside the outer casing 1 and prevents the heat generated by the cooling module 4 from accumulating inside the outer casing 1.

[0029] like Figure 4 and 5 As shown, a solenoid valve 5 is installed on the refrigerant line 3. The solenoid valve 5 is located between the condenser 42 and the evaporator, and the solenoid valve 5 is an expansion valve. The solenoid valve 5 is electrically connected to the control panel inside the vehicle 6. The solenoid valve 5 is opened or closed by the control panel, thereby controlling the supply and cut-off of the cold source in the refrigerant line 3.

[0030] like Figure 3 As shown, a fan 7 for heat dissipation is installed next to the condenser 42. When the fan 7 is working, it quickly dissipates the heat generated by the condenser 42, ensuring that the condenser 42 works normally.

[0031] like Figure 1-5 As shown, refrigerant pipe 3 is made of flexible pipe, which makes it easy for users to arrange refrigerant pipe 3.

[0032] This utility model also provides a vehicle 6, such as Figure 6 As shown, the vehicle 6 includes the aforementioned single-compressor multi-refrigeration-box vehicle-mounted refrigerator. The vehicle 6 has a compartment 62, and the single-compressor multi-refrigeration-box vehicle-mounted refrigerator is located within the compartment 62. Because the vehicle 6 includes the aforementioned vehicle-mounted refrigerator, this type of vehicle 6 also possesses the advantages and effects of an improved vehicle-mounted refrigerator, which will not be elaborated further here.

[0033] like Figure 6 As shown, the vehicle 6 has a storage compartment 61 located outside the carriage 62. Refrigerant pipes 3 are arranged inside the vehicle 6. The compressor 41 and condenser 42 can be detachably connected to the storage compartment 61. The housing 2 can be detachably connected to the carriage 62. The evaporator is installed inside the housing 2. The compressor 41, condenser 42 and evaporator are connected end to end in sequence through the refrigerant pipes 3.

[0034] Both the compressor 41 and the condenser 42 are heat-generating components. Users can install these components outside the vehicle compartment 62 to prevent the large amount of heat generated by the compressor 41 and condenser 42 from dissipating into the compartment 62. Furthermore, the noise generated by the compressor 41 and condenser 42 is minimally transmitted into the compartment 62, ensuring passenger comfort. Even when the refrigeration module 4 generates significant heat, it does not affect the use of the cabinet 2. This design also improves the cooling efficiency of the vehicle refrigerator. For example, in a motorhome, the cabinet 2 can be embedded in a cabinet. The storage compartment 61 is preferably located in a well-ventilated area of ​​the vehicle 6 (e.g., under the vehicle, with a sealed cover to prevent external dust from entering). This allows for more efficient heat dissipation from the compressor 41 and condenser 42, while avoiding thermal interference with the cabinet 2, especially advantageous in high-temperature environments (in summer, inside the vehicle, in the kitchen). The evaporator is a heat-absorbing component used to absorb heat from the cabinet 2, thus lowering its internal temperature.

[0035] It should be noted that vehicle 6 has wiring holes, and air conditioning pipes are arranged in the wiring holes. Refrigerant pipe 3 is arranged in the wiring holes and located next to the air conditioning pipes. Vehicle 6 does not need to provide additional wiring holes for refrigerant pipe 3 because the refrigeration module 4 is separated from the box 2. The refrigerant pipe 3 can simply be installed in the wiring holes where the original air conditioning pipes of vehicle 6 are located. This is easy for workers to operate and does not increase the cost of installing this type of vehicle refrigerator.

[0036] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
