Description

Technical Field

[0001] This utility model relates to the field of energy storage devices, specifically to a prefabricated energy storage cabin. Background Technology

[0002] In the field of liquid-cooled energy storage devices, prefabricated energy storage compartments are key equipment in energy storage systems. They typically include modules such as battery clusters, PCS (converters), BMS (battery management system), EMS (electrical system), fire protection, temperature control, and power distribution. They employ a modular design for easy transportation and on-site installation. Traditional prefabricated energy storage compartments usually adopt a left-right partitioned layout, generally divided into battery compartments, control compartments, and fire protection compartments. To facilitate transportation and reduce costs, existing energy storage compartments are generally designed to be 20 feet in size. Since the battery compartment occupies most of the space in the prefabricated energy storage compartment, the liquid cooler is generally installed vertically, integrated into the control compartment using a side-entry and exhaust airflow system. However, the prefabricated energy storage modules are large in size, and the project site has limited space. Therefore, the gaps between the modules are small, and the hot air discharged from the liquid chiller tends to accumulate between adjacent modules. This trapped heat creates a "heat island effect," causing the liquid chiller and PCS (Precast Concentration System) to draw in hot air, reducing the overall system efficiency, especially in summer. The cooling efficiency of the liquid chiller drops significantly, the PCS equipment experiences derating, and even triggers high-temperature alarms, greatly reducing the operating efficiency of the energy storage system. Increasing the distance between the prefabricated modules would increase the footprint of the equipment, placing higher demands on the site.

[0003] Currently, prefabricated energy storage pods on the market generally suffer from difficulties in installing battery packs into clusters. This typically requires multiple people to manually push the battery packs into the clusters, which is not only labor-intensive and inefficient, but also easily damages the protective layer on the surface of the battery packs and cluster frame, leading to rusting of the prefabricated pod. In addition, existing prefabricated energy storage pod fire suppression systems are relatively compact. Traditional 20-foot prefabricated energy storage pods, due to size limitations, are mostly equipped only with perfluorohexanone or aerosol cluster-level spray systems, lacking a separate and complete fire-fighting water system. They only have a DN65 fire hose connection installed on the side. When a fire breaks out in the prefabricated energy storage pod, the spray position and height after filling the fire hose connection are limited, the internal space covered is small, the fire-fighting effect is poor, and there is a risk of the fire getting out of control. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a liquid-cooled energy storage chamber.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is as follows: A liquid-cooled energy storage chamber includes a battery compartment for storing a battery pack, a liquid cooler and a control compartment for installing a control system on one side of the battery compartment, the liquid cooler being located above the control compartment, and the side of the liquid cooler having an air inlet mesh for drawing in external cold airflow, and the top surface of the liquid cooler having an exhaust mesh for discharging internal hot airflow to the space above the liquid-cooled energy storage chamber. This liquid-cooled energy storage compartment is a prefabricated energy storage compartment, similar in shape to a shipping container. The battery compartment is located on one side, occupying most of the compartment, while the liquid cooler and control compartment are located on the other side, with the liquid cooler positioned above the control compartment. In this configuration, the liquid cooler is unobstructed on all four sides except for its bottom and the side facing the battery compartment. Under these conditions, air intake vents are installed on the sides of the liquid cooler to draw in external cold air, and exhaust vents are installed on the top to expel internal hot air to the space above the liquid-cooled energy storage compartment. When the liquid cooler is operating in a cycle, air is drawn in through the side air intake vents and expelled through the top exhaust vents. Because the hot air is exhausted to the top, it can be quickly carried away and replaced by the circulating air compared to the hot air accumulating in the gaps between adjacent liquid-cooled energy storage compartments. This significantly improves the heat dissipation environment, reduces the impact of the "heat island effect" of the energy storage power station, and lowers the heat accumulation around the liquid-cooled energy storage compartment.

[0006] Preferably, in the aforementioned liquid-cooled energy storage compartment, a liquid cooler mounting rack is provided above the control compartment. The liquid cooler is placed in the mounting rack, which has a protective plate to prevent it from detaching. The outer side and top of the mounting rack have perforations corresponding to the air inlet or exhaust mesh. This structure reduces the difficulty of installing the liquid cooler; during installation, the liquid cooler is simply placed into the mounting rack from the top according to a preset direction. After the liquid cooler is embedded in the rack, the protective plate effectively limits its position, preventing it from shaking or falling out of the perforations. The perforations cooperate with the air inlet and exhaust meshes, ensuring normal air intake and exhaust during operation.

[0007] Preferably, in the aforementioned liquid-cooled energy storage compartment, a vertical partition is provided between the battery compartment, the control compartment, and the liquid cooler. This vertical partition has several through holes for pipes and cables to pass through. The vertical partition separates the battery compartment from the control compartment, and the battery compartment from the liquid cooler, allowing for relatively independent spatial division of each functional module. Furthermore, to facilitate the connection of various pipelines between the battery compartment, the control compartment, and the liquid cooler, through holes of corresponding shapes can be made at appropriate positions on the vertical partition.

[0008] Preferably, in the aforementioned liquid-cooled energy storage compartment, the battery compartment is provided with multiple vertical beams, which are fixedly installed in the vertical direction. Multiple racks for placing the battery packs are provided on the beams at different heights. By setting up multiple layers of racks to hold multiple battery packs, the internal space of the battery compartment is fully utilized.

[0009] Preferably, in the aforementioned liquid-cooled energy storage chamber, the cluster frame includes a bottom surface and sides. The sides of the cluster frame are provided with first rollers to facilitate the sliding of the battery pack into the frame. The upper and lower surfaces of the bottom surface of the cluster frame are respectively provided with second and third rollers. When the battery pack is inserted into the cluster, its sides contact the first rollers, its bottom surface contacts the second rollers, and its top surface contacts the third rollers of the upper cluster frame. The use of rollers in multiple directions reduces friction between the battery pack and the cluster frame, thereby reducing insertion resistance, reducing worker workload, and improving insertion efficiency. Furthermore, it reduces wear on the battery pack and the cluster frame, especially wear on the battery pack, thus improving the safety of the liquid-cooled energy storage chamber.

[0010] Preferably, in the aforementioned liquid-cooled energy storage chamber, the top of the cluster frame is provided with a bending limiter for guiding and limiting the sliding-in battery pack. The bending limiter can limit the side of the battery pack, ensuring that the battery pack does not wobble in the lateral direction. At the same time, the bending limiter can also play a guiding role when the battery pack enters the cluster, preventing the battery pack from deviating during entry and causing improper installation.

[0011] Preferably, in the aforementioned liquid-cooled energy storage chamber, a limiting member is detachably fixed at the front end of the cluster frame, and a bent edge is provided at the rear end of the cluster frame, with shock-absorbing pads on the bent edge. Before the battery pack enters the cluster, the limiting member is in a detached and uninstalled state. After the battery pack enters the cluster, the detachable limiting member is fixedly installed at the front end of the cluster frame. At this time, the battery pack is fixed between the front limiting member and the bent edge at the rear end. Since the bent edge at the rear end has a certain curvature and is provided with shock-absorbing pads, it can play a certain buffering role, thereby ensuring that the battery pack will not be significantly bumped during transportation.

[0012] Preferably, in the aforementioned liquid-cooled energy storage compartment, the battery compartment is equipped with a fire sprinkler system. The fire sprinkler system includes a top horizontal pipe fixedly installed at the top of the battery compartment. The top horizontal pipe has several nozzles for downward water spraying. The fire sprinkler system also includes a connecting pipe and a fire hose connection. The top horizontal pipe is connected to the fire hose connection via the connecting pipe. The top horizontal pipe is located at the top of the battery compartment and is arranged along the length of the battery compartment. In the event of a fire, the fire hose connection connects to external water, and the external water flows through the connecting pipe to the top horizontal pipe. Multiple nozzles can spray downwards over a wide area, forming a high-pressure water mist that covers the entire compartment, achieving rapid cooling of the battery compartment, reducing fire damage, and offering advantages such as large spray coverage area, good spray effect, ability to reduce internal temperature, and improved fire extinguishing effect.

[0013] Preferably, in the aforementioned liquid-cooled energy storage compartment, the connecting pipe includes a main connecting pipe and a vertical connecting pipe. The main connecting pipe is located at the bottom of the liquid-cooled energy storage compartment. One end of the main connecting pipe is connected to the fire hose connector, and the other end is connected to the vertical connecting pipe. The vertical connecting pipe is arranged vertically between the upright beams and the cluster frame of the battery compartment, and the other end of the vertical connecting pipe is connected to the top horizontal pipe. This pipe arrangement method occupies less space within the battery compartment, makes full use of the bottom space and the space between the upright beams and the cluster frame for pipe arrangement, and is easy to install, reducing the difficulty of installing the fire water system.

[0014] Preferably, the liquid-cooled energy storage compartment described above has a base at its bottom, on which a first maintenance plate and a second maintenance plate are mounted. The first maintenance plate is located at the bottom of the control compartment, and the second maintenance plate is located at the bottom of the battery compartment. Both the first and second maintenance plates consist of multiple interlocking panels. The use of multiple interlocking panels in the first and second maintenance plates facilitates maintenance, repair, and installation of main pipes.

[0015] Compared with the prior art, the advantages of this utility model are: The energy storage prefabricated compartment of this utility model places the liquid cooler on top, and the liquid cooler adopts a side air intake and top air exhaust method. When the liquid cooler is working in a cycle, air is drawn in from the side air intake mesh and air is exhausted from the top exhaust mesh. Since the hot air is exhausted to the top, compared with the accumulation in the gap between adjacent liquid-cooled energy storage compartments, the hot air at the top can be quickly carried away and replaced by the circulating air, thereby greatly improving the heat dissipation environment, reducing the impact of the "heat island effect" of the energy storage power station, reducing the heat accumulation around the liquid-cooled energy storage compartment, and helping to improve the operating efficiency of the liquid-cooled energy storage compartment system in the energy storage power station.

Detailed Implementation

[0029] To facilitate understanding of this utility model, the following description will be provided in more comprehensive and detailed manner with reference to the accompanying drawings and preferred embodiments. However, the scope of protection of this utility model is not limited to the following specific embodiments.

[0030] like Figures 1 to 4As shown, the liquid-cooled energy storage compartment of this embodiment includes a battery compartment 3 for storing battery packs 31. A liquid cooler 2 and a control compartment 1 for installing the control system are located on one side of the battery compartment 3. The liquid cooler 2 is positioned above the control compartment 1, and its side is provided with an air inlet mesh 23 for drawing in external cold airflow. The top surface of the liquid cooler 2 is provided with an exhaust mesh 22 for discharging internal hot airflow to the space above the liquid-cooled energy storage compartment. Specifically, the liquid-cooled energy storage compartment of this embodiment adopts a layout similar to an inverted L-shape. The liquid-cooled energy storage compartment is a rectangular structure in the shape of a container, with the control compartment 1 on the lower left, the liquid cooler 2 on the upper left, and the battery compartment 3 on the right. The control compartment 1 is equipped with a control cabinet 11, which integrates a control system for the normal operation of the liquid-cooled energy storage compartment, such as a fire control system 12. This is prior art, and any existing control compartment capable of controlling the operation of the liquid-cooled energy storage compartment can be used here. Furthermore, the specific structure and working principle of the control compartment 1 are not the subject of this utility model claim, therefore its detailed structure will not be described in detail. The liquid chiller 2 is specifically an open-air horizontal liquid chiller located directly above the control compartment 1. The liquid chiller 2 has air inlet mesh 23 on one front and two sides, an exhaust mesh 22 on the top, and a liquid supply port 24 and a liquid return port 25 on the bottom. The liquid supply port 24 and the liquid return port 25 are connected to the liquid cooling pipeline 34 via adapters. The specific structure and working principle of the liquid chiller 2 are also prior art, and any existing liquid chiller 2 capable of liquid cooling heat exchange can be used here. Furthermore, the specific structure and working principle of the liquid chiller 2 are not the subject of this utility model claim, therefore its detailed structure will not be described in detail. The battery compartment 3 integrates structures such as battery packs 31, cluster frames 32, and upright beams 33. It also includes fire-fighting piping for extinguishing fires and liquid-cooling piping 34 for reducing internal temperature. The specific internal structure and working principle of the battery compartment 3 are existing technologies, and existing battery compartment 3s can also be applied here; therefore, its detailed structure will not be elaborated upon. The exhaust mesh 22 of the liquid cooler 2 faces upwards, meaning hot air is exhausted to the top of the liquid-cooled energy storage compartment. The top space of the energy storage power station is relatively open, which is conducive to the natural circulation, diffusion, and replacement of hot air. If the natural circulation and diffusion of hot air is not effective, fans or other devices that facilitate air circulation and replacement can be installed in the top space of the liquid-cooled energy storage compartment to better blow away the hot air in the top space. This embodiment improves the "heat island effect" of the energy storage power station and increases system operating efficiency by placing the liquid cooler 2 at the top, with side air intake and top air exhaust.

[0031] In this embodiment, a liquid cooler mounting rack is provided above the control compartment 1, and the liquid cooler 2 is placed in the mounting rack. The mounting rack is provided with a protective plate 21 to prevent the liquid cooler 2 from detaching from it. The outer side and top of the mounting rack are provided with perforations corresponding to the air inlet mesh 23 or the exhaust mesh 22. Specifically, the liquid cooler mounting rack is a frame structure, including multiple frame rods, with an internal installation space for the liquid cooler 2 to be embedded. The perforations are located between the frame rods, and the protective plate 21 extends outward from the frame rods, specifically including two front protective plates and a bottom protective plate, which can limit and fix the liquid cooler 2 to prevent it from falling out of the perforations.

[0032] In this embodiment, a vertical partition 35 is provided between the battery compartment 3 and the control compartment 1 and the liquid cooler 2. The vertical partition 35 has several through holes for pipes and cables to pass through. Specifically, the fire-fighting pipes and liquid-cooling pipes 34 installed in the battery compartment 3 pass through the through holes on the vertical partition 35 and connect to the control compartment 1 or the liquid cooler 2. The joints are fixed with clamps. The cables in the control cabinet 11 also pass through the through holes on the vertical partition 35 and connect to the power lines of the battery pack 31.

[0033] In this embodiment, the battery compartment 3 is provided with multiple vertical beams 33, which are fixedly installed in the vertical direction. Multiple clusters 32 for placing battery packs 31 are provided on the vertical beams 33 at different heights. Specifically, the clusters 32 are fastened to the vertical beams 33 with bolts to form multiple battery placement layers at different heights. The top and bottom of the vertical beams 33 are fixedly connected to the frame of the battery compartment 3 by welds.

[0034] like Figures 5 to 9 As shown, in this embodiment, the cluster frame 32 includes a bottom surface 321 and a side surface 322. The side surface 322 is provided with a first roller 327 to facilitate the sliding of the battery pack 31 into the cluster frame 32. The upper and lower surfaces of the bottom surface 321 are respectively provided with a second roller 328 and a third roller 329. Specifically, the battery pack 31 includes a battery pack body and a bottom seat. The battery pack body is rectangular, and its bottom is provided with a bottom seat. The width of the bottom seat is slightly larger than the width of the battery pack body. When the battery pack 31 enters the cluster, the side surface of the bottom seat contacts the first roller 327, the bottom surface of the bottom seat contacts the second roller 328, and the top of the battery pack body contacts the third roller 329 of the cluster frame 32 above it. The smooth entry of the battery pack 31 into the cluster is achieved through the rollers in three directions.

[0035] In this embodiment, the top of the cluster frame 32 is provided with a bending limiter 323 for guiding and limiting the sliding battery pack 31. Specifically, the bending limiter 323 is located above the side surface 322 of the cluster frame and parallel to the bottom surface 321 of the cluster frame. When the battery pack 31 enters the cluster, the bending limiter 323 can guide the two sides of the battery pack body to prevent it from deviating from the center direction when sliding into the cluster frame 32. After the battery pack 31 is fixed, the bending limiter 323 can also limit the two sides of the battery pack body to prevent the battery pack 31 from shaking significantly in the left and right directions during transportation.

[0036] In this embodiment, a limiting member 326 is detachably fixed to the front end of the cluster frame 32, and a bent edge 324 is provided at the rear end of the cluster frame 32, with a shock-absorbing pad 325 provided on the bent edge 324. Specifically, the limiting member 326 is a detachably installable limiting plate with bolt holes. The limiting plate can be detachably fixed to the front end of the cluster frame 32 by front fixing bolts and side fixing bolts. The bent edge 324 is fixed to the rear end of the cluster frame 32 and has a certain bending angle, providing a buffer space for bending deformation. Together with the shock-absorbing pad 325, it can play a certain buffering role while fixing the battery pack.

[0037] like Figures 10 to 12 As shown, in this embodiment, a fire sprinkler assembly 5 is provided inside the battery compartment 3. The fire sprinkler assembly 5 includes a top horizontal pipe 52, which is fixedly installed on the top of the battery compartment 3. The top horizontal pipe 52 is provided with several nozzles 53 for spraying water downwards. The fire sprinkler assembly 5 also includes a connecting pipe and a fire hose connector 51. The top horizontal pipe 52 is connected to the fire hose connector 51 through the connecting pipe. Specifically, the top horizontal pipe 52 is fixed at the top along the length of the battery compartment 3, and the multiple nozzles 53 are arranged at intervals. Fire water enters the connecting pipe through the fire hose connector 51, then enters the top horizontal pipe 52 through the connecting pipe, and finally sprays out from the nozzles 53 from top to bottom.

[0038] In this embodiment, the connecting pipe includes a main connecting pipe 54 and a vertical connecting pipe 55. The main connecting pipe 54 is located at the bottom of the liquid-cooled energy storage compartment. One end of the main connecting pipe 54 is connected to the fire hydrant 51, and the other end is connected to the vertical connecting pipe 55. The vertical connecting pipe 55 is arranged vertically between the upright beam 33 and the cluster frame 32 of the battery compartment 3. The other end of the vertical connecting pipe 55 is connected to the top horizontal pipe 52. Specifically, the main connecting pipe 54 is connected to the fire hydrant 51 through a pipe (not shown in the figure) below the base 6. Cluster frames 32 are fixedly installed on both sides of the upright beam 33. The space between the cluster frames 32 on the left and right sides of the upright beam 33 and the space between the upright beam 33 can be used to arrange the vertical connecting pipe 55, making full use of the space for pipe arrangement and improving the overall compactness of the battery compartment 3 structure.

[0039] In this embodiment, the bottom of the liquid-cooled energy storage compartment is provided with a base 6, and a first maintenance plate 61 and a second maintenance plate 62 are provided on the base 6. The first maintenance plate 61 is located at the bottom of the control compartment 1, and the second maintenance plate 62 is located at the bottom of the battery compartment 3. Both the first maintenance plate 61 and the second maintenance plate 62 include multiple splicing panels. Specifically, the first maintenance plate 61 and the second maintenance plate 62 are each composed of two splicing panels. During maintenance, the splicing panels can be disassembled to perform maintenance on the control compartment 1 and the battery compartment 3 separately.

[0040] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
