Description

TECHNICAL FIELD

[0001] The present application relates to the packaging technical field, and particularly relates to a packaging box for a direct cooling pipeline of an energy storage cabinet. BACKGROUND

[0002] With the rapid development of energy storage technology, energy storage cabinets are widely used in intelligent power grids, distributed energy systems, new energy vehicle charging facilities and many other fields. An energy storage cabinet is usually composed of a cabinet body, a battery module, a control system and a thermal management system. The direct cooling pipeline in the thermal management system plays a crucial role in maintaining the stability of the working temperature of the battery module. The direct cooling pipeline effectively removes the heat generated during the operation of the battery through the circulation of the cooling liquid, thereby ensuring the efficient and safe operation of the energy storage cabinet.

[0003] In the delivery process, the pipeline for air conditioning is an online pipeline, which is designed in a disc shape and placed in the packaging box of the outdoor unit for packaging with the outdoor unit. For various shaped formed pipelines used in the air conditioning unit, no special packaging protection is currently used in large-scale delivery, and a mode of transporting by a tool car is usually adopted. However, this mode is not suitable for the direct cooling pipeline of the energy storage direct cooling project.

[0004] For the energy storage direct cooling project, the direct cooling pipeline needs to be formed and then transported to the energy storage integrated manufacturer for pipe assembly. Because the formed pipelines have different shapes and are larger than the direct cooling unit, the pipelines cannot be protected by being packaged with the unit. At the same time, because the demand for the direct cooling pipeline varies greatly among customers, the mode of large-scale delivery by a tool car is also not suitable for the delivery and protection of the direct cooling pipeline. At present, in the delivery process of the energy storage cabinet, there is no mature and suitable packaging solution for the formed pipeline used in the direct cooling system. INNOVATION CONTENT

[0005] In view of the deficiencies in the related art, the present application provides a packaging box for a direct cooling pipeline of an energy storage cabinet, which is designed according to the structural characteristics of the direct cooling pipeline, meets the protection requirements in the delivery process of the pipeline, avoids problems such as deformation of the pipeline caused by transportation, and is convenient for storage and transportation.

[0006] The first aspect of the present application provides a packaging box for a direct cooling pipeline of an energy storage cabinet, which is used for packaging the direct cooling pipeline of the energy storage cabinet. The energy storage cabinet includes a cabinet body, the cabinet body defines an energy storage compartment and a refrigeration compartment inside, a plurality of battery modules are arranged in the energy storage compartment, a refrigeration device is arranged in the refrigeration compartment, a plurality of direct cooling plates are arranged in the energy storage compartment and correspond to the plurality of battery modules one by one, and the direct cooling pipeline connects the refrigeration device and the plurality of direct cooling plates to form a refrigerant circulation loop.

[0007] The direct cooling pipeline includes a primary pipeline, a secondary pipeline, and multiple tertiary pipelines; the primary pipeline connects to the refrigeration equipment and extends to the energy storage compartment; the secondary pipeline connects to the primary pipeline and is located inside the energy storage compartment, passing by each direct cooling plate; each tertiary pipeline connects the secondary pipeline to a direct cooling plate to divert refrigerant from the secondary pipeline to the corresponding direct cooling plate, or to output refrigerant from the direct cooling plate to the secondary pipeline;

[0008] The packaging box includes a box body and a box lid; the box body has a defined receiving cavity with an open top. The bottom dimension of the receiving cavity is larger than the outer contour dimension of the maximum orthographic projection of the secondary pipeline, so that the secondary pipeline can be laid horizontally in the receiving cavity. The height of the receiving cavity is greater than the maximum diameter of the primary, secondary, and tertiary pipelines. The remaining space in the receiving cavity that is not occupied by the secondary pipeline is used to place the primary and tertiary pipelines. The box lid is placed on the box body and closes the receiving cavity.

[0009] The packaging box provided in this application is used to package the direct cooling pipeline of the energy storage cabinet. The internal dimensions of the box are designed to fully consider the size of the secondary pipeline, which has the largest overall dimensions. This allows the secondary pipeline to be laid horizontally within the cavity, while the remaining space can accommodate the primary and tertiary pipelines. This achieves packaging for all levels of pipeline while minimizing the size of the packaging box, making full use of the space within the cavity, and achieving a reasonable layout for the packaging of the direct cooling pipeline during shipment. This ensures the safety and stability of the direct cooling pipeline during transportation. Compared with packaging the pipeline and the entire unit together, this provides better protection for the pipeline and avoids the problem of large overall unit packaging. Compared with unpackaged pipeline transportation, it reduces the probability of pipeline deformation, allows for one-machine-one-material shipping, and is more adaptable to small-batch shipments.

[0010] In some embodiments, the secondary pipeline includes two first pipelines and a second pipeline; the two first pipelines are located on both sides of a plurality of direct cooling plates and pass by each direct cooling plate sequentially along the height direction of the energy storage compartment; the second pipeline connects the two first pipelines; the bottom of the receiving cavity is rectangular, the length of the cavity bottom is adapted to the length of the first pipeline, and the width of the cavity bottom is adapted to the length of the second pipeline.

[0011] In the above technical solution, for secondary pipelines with a specific structure, the packaging box is designed as a box with a rectangular cavity. The length of the rectangular cavity bottom is designed based on the length of the first pipeline, and the width is designed based on the length of the second pipeline, ensuring that the secondary pipeline can be accurately placed horizontally within the cavity. At the same time, the packaging box with these structural features is simpler in design, has lower manufacturing costs, and facilitates the packaging of pipelines at each stage.

[0012] In some embodiments, the secondary pipeline includes two first pipelines and a second pipeline; the two first pipelines are located on both sides of a plurality of direct cooling plates and pass by each direct cooling plate sequentially along the height direction of the energy storage compartment; the second pipeline connects the ends of the two first pipelines located on the same side; the housing includes two first sidewalls in the length direction and two second sidewalls in the width direction.

[0013] The receiving cavity includes a primary pipeline receiving area, a secondary pipeline receiving area, and a tertiary pipeline receiving area; the secondary pipeline receiving area includes two first regions adjacent to two first sidewalls and a second region adjacent to a second sidewall, the second region connecting the two first regions, and the secondary pipeline receiving area is used to receive secondary pipelines; the primary pipeline receiving area is located between the two first regions and is used to receive primary pipelines; the tertiary pipeline receiving area is located between the two first regions and is arranged side by side with the primary pipeline receiving area, and is used to receive tertiary pipelines.

[0014] In the above technical solution, the space inside the box cavity is reasonably divided according to the structural characteristics of each level of pipeline, realizing a zoned design, improving space utilization, optimizing the pipeline packaging layout, and improving the standardization of packaging operations.

[0015] In some embodiments, a first support structure is provided in two first regions, the first support structure being hollow inside to accommodate a first pipeline; and a second support structure is provided in a second region, the second support structure being hollow inside to accommodate a second pipeline.

[0016] In the above technical solution, by adding a first support structure and a second support structure within the secondary pipeline containment area, when the secondary pipeline is packaged, the first pipeline of the secondary pipeline is protected within the first support structure, and the second pipeline is protected within the second support structure, thereby providing protection and limiting function for the secondary pipeline, ensuring that the secondary pipeline will not be displaced or damaged due to vibration or collision during transportation, and improving the reliability and safety of the packaging box.

[0017] In some embodiments, the receiving cavity further includes an accessory receiving area, which is disposed side by side with the primary pipeline receiving area and the tertiary pipeline receiving area between the two first areas for accommodating accessories.

[0018] In the above technical solution, the cavity is also divided into an accessory storage area. While packaging the pipeline, the accessories of the whole machine can also be packaged at the same time, which improves the space utilization. The clear partitioning also helps to quickly find the required parts during disassembly and assembly, improves the standardization of operations, and saves time and labor costs.

[0019] In some embodiments, the remaining space in the primary pipeline accommodating area, the tertiary pipeline accommodating area, and the accessory accommodating area that is not occupied by the corresponding pipeline or accessory is filled with filler material to limit and buffer the corresponding pipeline or accessory inside.

[0020] In the above technical solution, the remaining space in each containment area that is not occupied by the corresponding pipes or accessories is filled with filler material. The filler material can effectively limit and buffer the internal pipes or accessories, prevent the pipes or accessories from shifting or colliding with each other due to vibration or impact during transportation, reduce the risk of damage, and further improve the protective effect of the packaging box.

[0021] In some embodiments, a plurality of valves are spaced apart on the first pipeline, and an opening is provided on the first support structure for the valves to be exposed, thereby defining a limiting space for the valves between the first support structure and the filler.

[0022] In the above technical solution, the first support structure is designed with an opening corresponding to the valve position, thereby ensuring the operability of packaging the secondary pipeline as a whole during the packaging process and avoiding the complex operation of disassembling and assembling the valve due to packaging. In addition, a limiting space for the valve is defined between the first support structure and the filler, which plays a limiting and protective role for the valve, effectively preventing the valve from being accidentally rotated or damaged due to external forces during transportation.

[0023] In some embodiments, the box body and lid are made of corrugated cardboard; the filler, the first support structure and the second support structure are made of honeycomb cardboard, expandable polyethylene or expandable polystyrene.

[0024] In the above technical solutions, the combination of different materials fully leverages their respective structural and performance advantages, which can reduce packaging weight and costs while ensuring protective reliability, thus achieving a balance between protective performance, structural strength, and cost-effectiveness in the packaging box.

[0025] In some embodiments, multiple support legs are provided on the bottom outer side of the housing, forming a loading area between the multiple support legs.

[0026] In the above technical solution, the support legs not only provide stable support for the entire packaging box, but also create a loading area at the bottom of the packaging box that can be used for forklift loading, avoiding manual handling, greatly reducing labor intensity and potential risks during the handling process, and improving transportation efficiency.

[0027] The second aspect of this application provides a packaging box for the direct cooling pipeline of an energy storage cabinet, used to package the direct cooling pipeline of the energy storage cabinet. The energy storage cabinet includes a cabinet body, and the cabinet body defines an energy storage compartment and a cooling compartment. Multiple battery modules are disposed in the energy storage compartment. A cooling device is disposed in the cooling compartment. Multiple direct cooling plates are disposed in the energy storage compartment and correspond one-to-one with the multiple battery modules. The direct cooling pipeline connects the cooling device and the multiple direct cooling plates to form a refrigerant circulation loop.

[0028] The direct cooling pipeline includes a primary pipeline, a secondary pipeline, and multiple tertiary pipelines; the primary pipeline connects to the refrigeration equipment and extends to the energy storage compartment; the secondary pipeline connects to the primary pipeline and is located inside the energy storage compartment, passing by each direct cooling plate; each tertiary pipeline connects the secondary pipeline to a direct cooling plate to divert refrigerant from the secondary pipeline to the corresponding direct cooling plate, or to output refrigerant from the direct cooling plate to the secondary pipeline;

[0029] The packaging box includes a box body and a box lid; the box body has a defined receiving cavity with an open top, and the dimensions of the receiving cavity are such that it can accommodate a horizontally laid secondary pipeline, and the remaining space not occupied by the secondary pipeline can accommodate a primary pipeline and a tertiary pipeline; the box lid is placed on the box body and closes the receiving cavity.

[0030] The packaging box provided in this application is used to package the direct cooling pipeline of the energy storage cabinet. The internal cavity of the box is sized to allow the secondary pipeline to be laid horizontally within the cavity, while the remaining space not occupied by the secondary pipeline can accommodate the primary and tertiary pipelines. This packaging design achieves packaging for each level of pipeline while minimizing the size of the packaging box, fully utilizing the space within the cavity, and realizing a rational layout for the packaging of the direct cooling pipeline during shipment, ensuring the safety and stability of the pipeline during transportation. Compared to packaging the pipeline and the entire unit together, this provides better protection for the pipeline, avoids the problem of large overall unit packaging, and eliminates pipeline deformation issues. Compared to transporting pipelines without packaging, it allows for one-unit-one-material shipment, making it more adaptable to small-batch shipments. Attached Figure Description

[0043] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0048] For direct-cooling energy storage projects, the direct-cooling pipelines need to be pre-formed and transported to the energy storage integration manufacturer for piping assembly. Because the pre-formed pipelines vary in shape and are larger than the direct-cooling units, they cannot be packaged in the same way as the units for protection. Furthermore, due to significant differences in the quantity of direct-cooling pipelines required by different customers, the large-scale shipment method using tooling trucks is not suitable for the protection of the pipelines during shipment. Currently, there is no mature and suitable packaging solution for pre-formed pipelines used in direct-cooling systems during the shipment of energy storage cabinets.

[0049] Based on this, this application provides a packaging box for the direct cooling pipeline of an energy storage cabinet, which is designed according to the structural characteristics of the direct cooling pipeline of the energy storage cabinet to meet the protection requirements during the pipeline delivery process. It effectively solves the problems of deformation and damage that may occur in the pipeline due to external forces such as collision, squeezing and friction during transportation, meets the convenience of delivery of one set of pipelines for one unit, facilitates warehousing and transportation, and improves delivery efficiency.

[0050] like Figure 1 As shown, an energy storage cabinet is a device used to store and manage electrical energy, typically including a cabinet, energy storage elements, and a temperature control system. By storing electrical energy in energy storage elements and using a temperature control system to ensure that the energy storage elements operate at the optimal operating temperature, the energy storage cabinet can achieve efficient storage and release of electrical energy, meeting the power needs of different scenarios.

[0051] The internal structure of the energy storage cabinet is divided into an energy storage compartment and a refrigeration compartment. For example, the internal space can be divided according to functional needs using partitions or other means.

[0052] Multiple battery modules are installed inside the energy storage compartment. Figure 1 (Not shown in the image). Multiple battery modules can be arranged along the height of the energy storage compartment. As energy storage elements, battery modules generate heat during charging and discharging, and temperature has a crucial impact on battery performance, lifespan, and safety.

[0053] The refrigeration chamber is equipped with a refrigeration device 11. Optionally, the refrigeration device 11 adopts a liquid cooling method, which uses liquid refrigerant to circulate in pipes or direct cooling plates. The refrigerant absorbs the heat generated by the battery module and carries the heat away from the battery module, effectively controlling the temperature of the battery module and ensuring that it operates within the optimal operating temperature range, thereby improving the battery's performance, lifespan, and safety.

[0054] See Figure 1 Multiple direct-cooling plates 12 are also installed inside the energy storage compartment, each corresponding to one of the aforementioned battery modules. In some embodiments, each direct-cooling plate 12 is directly mounted on the surface of its corresponding battery module, fitting snugly against it. The shape and size of the direct-cooling plate 12 are designed according to the shape of the battery module to ensure maximum contact area and optimal heat conduction. The direct-cooling plate 12 has internal refrigerant channels. Refrigerant is transported from the refrigeration equipment 11 through pipes to the refrigerant channels inside each direct-cooling plate 12. After absorbing heat from the corresponding battery module, the refrigerant returns to the refrigeration equipment 11 through pipes for cooling.

[0055] The energy storage cabinet also includes direct cooling pipes, which connect the refrigeration equipment 11 and the aforementioned multiple direct cooling plates 12, thereby forming a refrigerant circulation loop. For example... Figure 1 As shown, the direct cooling pipeline includes a primary pipeline 131, a secondary pipeline 132, and a tertiary pipeline 133.

[0056] The primary piping 131 connects to the refrigeration unit 11 and extends to the energy storage compartment. The primary piping 131 includes at least a refrigerant output piping and a refrigerant return piping. One end of the refrigerant output piping connects to the liquid outlet of the refrigeration unit 11, and the other end extends to the energy storage compartment, used to deliver the refrigerant output from the refrigeration unit 11 into the energy storage compartment. One end of the refrigerant return piping connects to the liquid return port of the refrigeration unit 11, and the other end extends to the energy storage compartment, used to return the refrigerant, which has been heated by heat exchange with the direct cooling plate 12, to the refrigeration unit 11 for cooling. Considering the utilization rate of the internal space of the energy storage cabinet, the distance between the refrigeration unit 11 and the energy storage compartment is usually not too far; therefore, the length of the primary piping 131 is relatively short, and its overall size is small.

[0057] The secondary pipeline 132 is located inside the energy storage compartment and connects to the primary pipeline 131. The secondary pipeline 132 passes by each direct cooling plate 12 within the energy storage compartment, delivering the refrigerant supplied by the primary pipeline 131 to positions close to each direct cooling plate 12. To increase energy storage capacity, the energy storage compartment inside the energy storage cabinet occupies a large space, allowing for the placement of more battery modules. The secondary pipeline 132 needs to traverse the direct cooling plates 12 corresponding to each battery module to ensure effective cooling for each module; therefore, the overall size of the secondary pipeline 132 is relatively large. "Traversing" here means that the arrangement path of the secondary pipeline 132 passes through the positions of the direct cooling plates 12 corresponding to each battery module within the energy storage compartment, without missing any direct cooling plate 12, and each direct cooling plate 12 is traversed only once.

[0058] Multiple tertiary pipes 133 are provided. Each tertiary pipe 133 connects a secondary pipe 132 to a direct cooling plate 12. It is used to distribute the refrigerant in the secondary pipe 132 to each direct cooling plate 12, or to output the refrigerant after heat exchange in the direct cooling plate 12 to the secondary pipe 132. Since the secondary pipe 132 passes through each direct cooling plate 12, the tertiary pipes 133 only need to connect the direct cooling plate 12 to the secondary pipe 132 at the corresponding position of each direct cooling plate 12. Therefore, the length of each tertiary pipe 133 is relatively short, and the overall size is small.

[0059] Since the largest component determines the outer shape and internal space layout of the packaging box during the packaging process, the dimensions of the secondary cooling pipe 132 were used as the design benchmark during the packaging box design process. After determining the overall external dimensions, the internal layout of the packaging box was also designed around the secondary cooling pipe 132 to ensure that the secondary cooling pipe 132 could be properly placed. At the same time, the reasonable layout of other direct cooling pipes at all levels within the box was also taken into account, thereby effectively improving the space utilization and protective performance of the packaging box.

[0060] Based on the characteristics of the direct cooling pipeline inside the energy storage cabinet, this application provides a packaging box for the direct cooling pipeline of the energy storage cabinet. Two embodiments are described below.

[0061] The following, combined with Figures 2-8 The packaging box provided in the first embodiment of this application will be described.

[0062] The packaging box includes a box body 2, and the box body 2 defines a receiving cavity 21 inside. The top of the receiving cavity 21 is open to facilitate the placement and removal of the direct cooling pipes. The bottom dimension of the receiving cavity 21 is larger than the outer contour dimension of the maximum orthographic projection of the secondary pipe 132, so that the secondary pipe 132 can be placed horizontally inside the receiving cavity 21. The height of the receiving cavity 21 is greater than the maximum diameter of the primary pipe 131, the secondary pipe 132, and the tertiary pipe 133. The remaining space in the receiving cavity 21 not occupied by the secondary pipe 132 is used to place the primary pipe 131 and the tertiary pipe 133.

[0063] The packaging box also includes a lid 3, which is placed on the box body 2 and seals the receiving cavity 21. During the packaging process, the lid 3 can be fixed to the box body 2 by various methods such as pasting, bolting, and snap-fit ​​connection, to prevent the items inside the box body 2 from being lost during transportation and to ensure that the packaging box can fully protect the internal pipelines during transportation.

[0064] The following, combined with Figures 2-8 The packaging box provided in the second embodiment of this application will be described.

[0065] The housing 2 has an internal cavity 21 with an open top. The cavity 21 is sized to accommodate a horizontally placed secondary pipeline 132, and the remaining space not occupied by the secondary pipeline 132 can accommodate a primary pipeline 131 and a tertiary pipeline 133.

[0066] The lid 3 is placed on the box body 2 and seals the receiving cavity 21. During the packaging process, the lid 3 can be fixed to the box body 2 by various methods such as pasting, bolting, and snap-fit ​​connection. During transportation, it prevents the items inside the box body 2 from being lost and ensures that the packaging box can fully protect the internal pipelines during transportation.

[0067] It is understood that the structures of the packaging boxes defined by the two embodiments above may overlap, and should not be interpreted as mutually exclusive definitions.

[0068] The packaging box provided in this application is used to package the direct cooling pipeline of the energy storage cabinet. The direct cooling pipeline is divided into a primary pipeline 131, a secondary pipeline 132, and a tertiary pipeline 133. The size design of the internal cavity 21 of the box body 2 fully considers the size characteristics of the secondary pipeline 132, which has the largest overall size. This allows the secondary pipeline 132 to be placed horizontally in the cavity 21. The remaining space not occupied by the secondary pipeline 132 can accommodate the primary pipeline 131 and the tertiary pipeline 133. This not only achieves packaging of each level of pipeline, but also minimizes the size of the packaging box. It makes full use of the space inside the cavity 21, achieves a reasonable layout for the shipping packaging of the direct cooling pipeline, and ensures the safety and stability of the direct cooling pipeline during transportation.

[0069] The packaging solution of this application adopts a flat structure for the box body 2, with the length and width dimensions being greater than the height dimension, so that the entire pipeline is placed horizontally within the receiving cavity 21. Compared with packaging the pipeline and the whole machine together, it provides better protection for the pipeline, avoids the problem of large packaging size for the whole machine, and eliminates the problem of pipeline deformation. Compared with unpackaged pipeline transportation, it can achieve one machine per material shipment, which is more adaptable to small batch shipments.

[0070] The technical features of the packaging box are further described below. It should be noted that the solutions described in the following embodiments are also applicable to packaging boxes having the above two embodiments.

[0071] The structure of the packaging box is further defined based on different structures of the direct cooling pipeline. In some embodiments, such as Figure 1 As shown, the secondary pipeline 132 in the direct cooling pipeline includes two first pipelines 1321 and one second pipeline 1322. The two first pipelines 1321 are located on both sides of the multiple direct cooling plates 12, extending along the height direction of the energy storage compartment and passing sequentially beside each direct cooling plate 12. The second pipeline 1322 connects the two first pipelines 1321. The first pipelines 1321 pass sequentially beside each direct cooling plate 12 along the height direction, while the second pipeline 1322 connects the two first pipelines 1321, forming a loop for the refrigerant inside the energy storage compartment. Since the first pipelines 1321 pass beside each direct cooling plate 12 along the height direction, the length of the first pipeline 1321 is greater than the length of the second pipeline 1322, and the length of the second pipeline 1322 is slightly greater than the width of the direct cooling plate 12. It is understood that, depending on the design of the refrigerant routing inside the energy storage compartment, other first pipelines 1321 may be included, depending on the specific requirements.

[0072] In some embodiments, the packaging box is designed for the secondary pipeline 132 with the above structure, such that the bottom of the receiving cavity 21 is rectangular, the length of the bottom of the cavity is adapted to the length of the first pipeline 1321, and the width of the bottom of the cavity is adapted to the width of the second pipeline 1322, so that the size of the receiving cavity 21 inside the box body 2 is larger than the size of the secondary pipeline 132, and the secondary pipeline 132 can be placed horizontally in the receiving cavity 21.

[0073] In the above embodiment, for the secondary pipeline 132 with the specific structure described above, the packaging box is designed as a box 2 with a rectangular cavity. Considering the structural characteristics inside the energy storage compartment, the length of the first pipeline 1321 is greater than the length of the second pipeline 1322. Therefore, the length of the rectangle is designed based on the length of the first pipeline 1321, and the width of the rectangle is designed based on the length of the second pipeline 1322, ensuring that the secondary pipeline 132 can be accurately placed horizontally within the receiving cavity 21. At the same time, the packaging box with the above structural characteristics has a simpler design, lower manufacturing cost, and facilitates the packaging of pipelines at all levels.

[0074] In some embodiments, the second conduit 1322 connects the ends of two first conduits 1321 located on the same side; in this case, the area between the two first conduits 1321 is continuous. For this type of secondary conduit 132, the space of the packaging box's receiving cavity 21 is rationally arranged.

[0075] like Figures 3-7 As shown, the housing 2 includes two first sidewalls 221 in the length direction and two second sidewalls 222 in the width direction; the receiving cavity 21 is divided into a primary pipeline receiving area 211, a secondary pipeline receiving area 212, and a tertiary pipeline receiving area 213; wherein, the secondary pipeline receiving area 212 includes two first regions 2121 respectively close to the two first sidewalls 221, and a second region 2122 close to one of the second sidewalls 222, the second region 2122 connecting the two first regions 2121, and the secondary pipeline receiving area 212 is used to receive secondary pipelines 132; the primary pipeline receiving area 211 and the tertiary pipeline receiving area 213 are arranged side by side between the two first regions 2121, the primary pipeline receiving area 211 is used to receive primary pipelines 131, and the tertiary pipeline receiving area 213 is used to receive tertiary pipelines 133.

[0076] In the above embodiments, the space within the accommodating cavity 21 of the packaging box is rationally divided according to the structural characteristics of each level of pipeline, thereby achieving a partitioned design, improving space utilization, optimizing the pipeline packaging layout scheme, and enhancing the standardization of packaging operations.

[0077] In some embodiments, a first support structure 41 is provided in two first regions 2121, the first support structure 41 being hollow inside to accommodate a first pipe 1321; and a second support structure 42 is provided in a second region 2122, the second support structure 42 being hollow inside to accommodate a second pipe 1322.

[0078] In the above embodiment, by adding a first support structure 41 and a second support structure 42 within the secondary pipeline receiving area 212, the first support structure 41 and the second support structure 42 are designed along the direction of the secondary pipeline 132 and are hollow inside; when the secondary pipeline 132 is packaged, the first pipeline 1321 of the secondary pipeline 132 is protected within the first support structure 41, and the second pipeline 1322 is protected within the second support structure 42, thereby providing protection and limiting function for the secondary pipeline 132, ensuring that the secondary pipeline 132 will not be displaced or damaged due to vibration or collision during transportation, and improving the reliability and safety of the packaging box.

[0079] In the above embodiments, the first support structure 41 and the second support structure 42 can be formed by folding cardboard according to the outer diameter and length of the first pipe 1321 and the second pipe 1322, respectively.

[0080] In some embodiments, such as Figure 4 and Figure 7 As shown, the receiving cavity 21 also includes an accessory receiving area 214, which is arranged side by side with the primary pipeline receiving area 211 and the tertiary pipeline receiving area 213 between the two first areas 2121 to receive the complete set of accessories.

[0081] Through the above embodiments, the space inside the receiving cavity 21 between the two first regions 2121 is divided into a primary pipeline receiving area 211, a tertiary pipeline receiving area 213, and an accessory receiving area 214. All accessories can be packaged simultaneously, improving space utilization. The clear zoning also facilitates quick location of required components during disassembly and assembly, improving operational standardization and saving time and labor costs. The size of the three regions can be rationally arranged according to the corresponding pipelines or accessories to be accommodated.

[0082] For example, in Figure 7 In the illustrated embodiment, along the length of the housing 2, from the second region 2122 to the opposite side, there are sequentially a primary pipeline accommodating area 211, an accessory accommodating area 214, and a tertiary pipeline accommodating area 213. The arrangement of each level of pipeline within the corresponding area can be designed according to the pipeline size and the accommodating area size. It is understood that the positions of the above three areas can be interchanged according to actual conditions, and this application does not impose any restrictions.

[0083] In some embodiments, such as Figure 7 As shown, two partitions 5 are provided at intervals between two first regions 2121 inside the receiving cavity 21. The two partitions 5 divide the portion of the receiving cavity 21 located between the two first regions 2121 into a primary pipeline receiving area 211, a tertiary pipeline receiving area 213, and an accessory receiving area 214.

[0084] In the above embodiment, the internal area is divided using partition 5, which not only enables the classified placement of different components but also enhances the stability and reliability of the internal structure of the packaging box. Through this design, each area has a clear functional positioning; the primary pipeline 131, the tertiary pipeline 133, and accessories can be placed in their respective storage areas, avoiding collisions and interference between different components.

[0085] In some embodiments, such as Figure 7 As shown, the primary pipeline accommodating area 211, the tertiary pipeline accommodating area 213, and the accessory accommodating area 214 are each filled with filler material 6. The filler material 6 is used to fill the remaining space in the corresponding accommodating area that is not occupied by the corresponding pipeline or accessory, so as to limit and buffer the corresponding pipeline or accessory inside.

[0086] In the above embodiments, the remaining space in each receiving area not occupied by the corresponding pipes or accessories is filled with filler material 6. The filler material 6 can be designed according to the shape of the remaining space in the corresponding receiving area. On the one hand, the filler material can limit the pipes or accessories, preventing them from shifting due to external forces; on the other hand, the filler material can absorb and disperse the energy generated by vibration and impact, avoiding collisions between pipes or accessories. This significantly reduces the risk of damage to pipes or accessories due to external forces during transportation, further improving the protective performance of the packaging box for the direct cooling pipes of the energy storage cabinet, and further enhancing the protective effect of the packaging box.

[0087] In some embodiments, such as Figure 4 and Figure 7 As shown, a plurality of valves 14 are provided at intervals on the first pipeline 1321, and an opening for the valves 14 to be exposed is provided on the first support structure 41, and a limiting space for the valves 14 is defined between the first support structure 41 and the filler 6.

[0088] In the above embodiment, the first support structure 41 is designed with an opening for the valve 14 on the first pipeline 1321, thereby ensuring the operability of packaging the secondary pipeline 132 as a whole during the packaging process and avoiding the complex operation of disassembling and assembling the valve 14 due to packaging. In addition, a limiting space for the valve 14 is defined between the first support structure 41 and the filler 6. For example, the edge of the filler 6 is set close to the valve 14, which can prevent the valve 14 and the secondary pipeline 132 from shifting to a certain extent, thus protecting the valve 14 and effectively preventing the valve 14 from being accidentally rotated or damaged due to external forces during transportation. This further enhances the overall protection of the pipeline and its accessories by the packaging box.

[0089] In some embodiments, the box body 2 and the box lid 3 are made of corrugated cardboard; the filler 6, the first support structure 41, and the second support structure 42 are made of honeycomb cardboard. Corrugated cardboard, with its multi-layered corrugated structure, possesses excellent impact resistance and structural stability; honeycomb cardboard, with its unique honeycomb structure, possesses good cushioning performance and high compressive strength, and can be designed differently according to the shape of different pipelines, thereby meeting the limiting requirements of pipelines, while providing suitable space, height, and necessary packaging protection for pipelines or accessories.

[0090] The material combination described above fully leverages the structural advantages of both honeycomb cardboard and corrugated cardboard, reducing packaging weight and costs while ensuring reliable protection, thus achieving a balance between protective performance, structural strength, and cost-effectiveness in the packaging box.

[0091] In the above embodiments, the honeycomb paperboard can also be replaced with expandable polyethylene (EPS) or expandable polystyrene (EPE) as needed, which can further reduce costs, improve structural strength, facilitate processing, and be suitable for mass production.

[0092] In some embodiments, honeycomb cardboard is adhered to the inner sides of both the first sidewall 221 and the second sidewall 222 of the box body 2. The corrugated cardboard serves as the outer shell of the box body 2, while the honeycomb cardboard is internally wrapped, which not only enhances the structural strength of the honeycomb cardboard sides but also improves the overall durability of the packaging box, making it less prone to damage and deformation during transportation and increasing the reliability of the packaging box.

[0093] In some embodiments, such as Figure 9 and Figure 10 As shown, a bottom support plate 7 is also laid at the bottom of the receiving cavity 21. The bottom support plate 7 is made of honeycomb cardboard or EPE / EPS. The bottom support plate 7 serves as the main load-bearing structure of the entire box 2, and is integrated with the corrugated cardboard outer shell of the box 2 by adhesive bonding or other methods, jointly ensuring the overall support strength of the packaging box. Designed honeycomb cardboard is glued on top of the bottom support plate 7 as filler 6, the first support structure 41, and the second support structure 42.

[0094] In some embodiments, such as Figure 5 and Figure 8 As shown, to facilitate transportation and loading / unloading, multiple support legs 8 are provided on the outer bottom of the box 2, forming a loading area 9 between the support legs 8. The support legs 8 not only stably support the entire packaging box, but also form a loading area 9 at the bottom of the packaging box that can be used for forklift loading.

[0095] The above design effectively avoids manual handling, greatly reducing labor intensity and potential risks during the handling process, while improving transportation efficiency. The support legs 8 are firmly connected to the box body 2 using adhesives or other methods, ensuring the stability and reliability of the entire structure. It is understandable that for packaging boxes with relatively light piping, the support legs 8 may not be necessary, allowing for manual handling.

[0096] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
