Description

Technical Field

[0001] This utility model relates generally to the field of energy storage technology, and more specifically to an energy storage box and an energy storage system. Background Technology

[0002] With the development of the marine power industry, various energy storage containers that meet marine requirements have emerged.

[0003] Because these containers are used on ships, an accident could endanger all personnel on board. Marine energy storage containers must provide sufficient emergency response time even in the event of an internal accident. Therefore, traditional explosion venting methods cannot be used; the container must meet high fire and explosion protection requirements. Explosion-proof components are typically large, making internal layout difficult.

[0004] Due to space constraints, existing energy storage boxes have liquid-cooled main units located in the electrical compartment, requiring a separate ventilation system for heat exchange with the outside environment. This results in an overly compact layout within the electrical compartment, making it difficult to install the air duct system for the liquid cooling system and hindering heat dissipation within the electrical compartment.

[0065] Unless otherwise stated, the numerical ranges in this document include not only the entire range within its two endpoints, but also the subranges contained therein.

[0066] Figures 1 to 8An energy storage box according to the present invention is shown. The energy storage box includes a box body 100, which includes an electrical compartment 102, a liquid cooling compartment 103, and a battery compartment 101. The electrical compartment 102 is arranged along the length direction D1 at the first end of the box body 100 and is used to house and install electrical equipment. The liquid cooling compartment 103 is arranged along the length direction D1 at the second end of the box body 100 and communicates with the outside of the box body 100, and is used to house and install liquid cooling equipment. The battery compartment 101 is arranged at least partially along the length direction D1 of the box body 100 between the first and second ends and is used to house and install energy storage batteries.

[0067] The energy storage box also includes a fireproof component 170, which includes fireproof layers (specifically, the first fireproof layer 171, the second fireproof layer 172, and the third fireproof layer 173 described below). The battery compartment 101 has at least one fireproof layer on its side near the electrical compartment 102 and the liquid cooling compartment 103, and the bottom of the battery compartment 101 has at least two fireproof layers.

[0068] According to the energy storage box of this utility model, the liquid cooling chamber 103 and the electrical chamber 102 are arranged separately and are blocked by the fireproof component 170 of the battery chamber 101. This facilitates the installation of liquid cooling equipment and ensures the heat dissipation of the electrical chamber 102. In addition, the liquid cooling chamber 103 is connected to the outside of the box body 100, so there is no need to install a duct device, and it also ensures that the capacity of the battery chamber 101 will not be compressed.

[0069] The following is combined first Figures 1 to 3 The specific implementation method describes the main structure of the energy storage box 100.

[0070] Overall, referring to Figure 1 The housing 100 includes a base frame 110, a top frame 120, two end frames 140, and two side frames 150. The top frame 120 is spaced apart from the base frame 110 along the height direction D3 of the housing 100. The end frames 140 and side frames 150 are both located between the base frame 110 and the top frame 120. The two end frames 140 are respectively arranged at both ends of the base frame 110 along the length direction D1, and the two side frames 150 are arranged on both sides of the base frame 110 along the width direction D2. The end frames 140 are connected to the side frames 150, thus forming the overall structure of the housing 100, used to carry batteries or electrical equipment, etc.

[0071] The base frame 110 includes two bottom longitudinal beams 112, two bottom end beams 113, and four bottom corner pieces 111. The two bottom longitudinal beams 112 are spaced apart along the width direction D2, and both bottom longitudinal beams 112 extend along the length direction D1. The four bottom corner pieces 111 are respectively disposed at both ends of the two bottom longitudinal beams 112, and the two bottom end beams 113 are respectively disposed at both ends of the bottom longitudinal beams 112, with the ends of the bottom end beams 113 and the ends of the bottom longitudinal beams 112 connected to the bottom corner pieces 111.

[0072] Combination Figure 7 As shown, the base frame 110 also includes a bottom sealing plate 117, a central longitudinal beam 114, multiple second frames 115, and four third frames 116. The central longitudinal beam 114 extends along the length direction D1 of the box body 100, and is positioned between two bottom longitudinal beams 112 along the width direction D2, with both ends of the central longitudinal beam 114 connected to two bottom end beams 113 respectively. Multiple second frames 115 are arranged at intervals along the length direction D1 of the box body 100, and are positioned on both sides of the central longitudinal beam 114 along the width direction D2 of the box body 100. The four third frames 116 are positioned at both ends of the central longitudinal beam 114 in pairs, with the two third frames 116 located at the same end of the central longitudinal beam 114 positioned on both sides of the central longitudinal beam 114 along the width direction D2. The third frames 116 are constructed as square tubes, while the second frames 115 are constructed as beam structures with a C-shaped cross-section. Along the height direction D3 of the box body 100, the bottom sealing plate 117 is located below the second frame 115 and the intermediate longitudinal beam 114, and the bottom sealing plate 117 is connected to the bottom longitudinal beam 112 and the bottom end beam 113.

[0073] The aforementioned base frame 110 has a stable structure and adopts a fishbone-like structure formed by the middle longitudinal beam 114, the second frame 115 and the third frame 116, which is conducive to supporting the battery or electrical equipment inside the box 100.

[0074] Reference Figure 1 and Figure 3 The top frame 120 includes two top longitudinal beams 121, two top end beams 122, four top corner pieces 124, and a top plate 123. The top longitudinal beams 121 extend along the length direction D1, and the two top longitudinal beams 121 are spaced apart along the width direction D2. The top end beams 122 extend along the width direction D2, and the two top end beams 122 are respectively located at both ends of the top longitudinal beams 121. The four top corner pieces 124 are respectively located at both ends of the two top longitudinal beams 121, and the ends of the top end beams 122 are connected to the top corner pieces 124. The top plate 123 is disposed within the space surrounded by the two top longitudinal beams 121 and the two top end beams 122, and the top plate 123 is connected to the top longitudinal beams 121, the top end beams 122, and the top corner pieces 124.

[0075] The enclosure 100 also includes four corner posts 130, which are correspondingly arranged with four top corner pieces 124 or four bottom corner pieces 111. Along the height direction, the top of the corner post 130 is connected to the top corner piece 124, and the bottom of the corner post 130 is connected to the bottom corner piece 111. The side frames 150 and end frames 140 are constructed as frames or wall panels. The side frames 150 and end frames 140 can also be constructed as frames or wall panels with door and window structures, depending on the functional requirements of the compartments within the enclosure 100 (detailed below).

[0076] Optionally, refer to Figure 3 and Figure 4 The enclosure 100 also includes a first partition 160, which is disposed between the top frame 120 and the bottom frame 110, and is located at the second end of the enclosure 100 along the length direction D1. The first partition 160 has an L-shaped cross-section perpendicular to the height direction D3. The two ends of the first partition 160 are connected to the side frame 150 and the end frame 140, respectively, thereby forming a liquid-cooled chamber 103 from the first partition 160, the top frame 120, the bottom frame 110, the side frame 150, and the end frame 140. The first partition 160 ensures that the second end of the enclosure 100 forms a liquid-cooled chamber 103, resulting in a stable structure. Furthermore, the liquid-cooled chamber 103 is less likely to affect the electrical equipment in the electrical compartment 102 located at the first end of the enclosure 100.

[0077] Furthermore, the end frame 140 near the liquid cooling chamber 103 is provided with a mesh door 163 that connects to the liquid cooling chamber 103, and the side frame 150 near the liquid cooling chamber 103 is provided with a mesh window 164 that connects to the liquid cooling chamber 103. This allows the liquid cooling chamber 103 to communicate with the outside of the enclosure 100, enhancing the heat dissipation of the liquid cooling equipment inside the liquid cooling chamber 103. Therefore, the heat dissipation of the liquid cooling equipment can be guaranteed without the need for an air duct device.

[0078] Optionally, the enclosure 100 further includes a second partition 161, which is disposed between the top frame 120 and the bottom frame 110 and is arranged along the length direction D1 at the first end of the enclosure 100. The second partition 161 extends along the width direction D2 and is connected to the side frame 150, such that the second partition 161, the top frame 120, the bottom frame 110, the side frame 150, and the end frame 140 at least partially form the electrical compartment 102.

[0079] In addition, the first partition 160, the second partition 161, the top frame 120, the bottom frame 110, the side frame 150, and the end frame 140 are configured to form the battery compartment 101.

[0080] As can be seen from the above, along the length direction D1, the battery compartment 101 is generally arranged between the liquid cooling compartment 103 and the electrical compartment 102, which separates the liquid cooling compartment 103 and the electrical compartment 102, facilitating the arrangement of electrical equipment in the electrical compartment 102. Furthermore, the fireproof component 170 arranged in the battery compartment 101 can block the heat transfer between the liquid cooling compartment 103 and the electrical compartment 102, which is beneficial to ensuring the heat dissipation of the electrical compartment 102.

[0081] Optionally, the enclosure 100 further includes a third partition 162, which is disposed between the top frame 120 and the bottom frame 110 and is arranged along the length direction D1 at the first end of the enclosure 100. The cross-section of the third partition 162 perpendicular to the height direction D3 is L-shaped, and the two ends of the third partition 162 are respectively connected to the side frame 150 and the end frame 140, so that the third partition 162, the top frame 120, the bottom frame 110, the side frame 150 and the end frame 140 form a fire compartment 104 for accommodating and installing fire-fighting equipment.

[0082] In addition, the third partition 162, the second partition 161, the top frame 120, the bottom frame 110, the side frame 150 and the end frame 140 form an electrical compartment 102, which separates the fire-fighting equipment from the electrical equipment and helps to protect the electrical equipment in the electrical compartment 102.

[0083] Optionally, refer to Figure 1 The enclosure 100 is also equipped with a fire door 165, which is located on the side frame 150 and overlaps with the battery compartment 101 along the length direction D1, making it convenient for staff to enter the battery compartment 101.

[0084] Optionally, refer to Figure 3 The enclosure 100 is also equipped with an electrical door 166 and a maintenance door 167. The electrical door 166 is located on the end frame 140 at the first end of the enclosure 100, which facilitates the installation of electrical equipment into the electrical compartment 102 by personnel. The maintenance door 167 is located on the side frame 150 and coincides with the electrical compartment 102 along the length direction D1, which facilitates the entry of personnel into the electrical compartment 102 for maintenance.

[0085] Optionally, refer to Figure 3 The enclosure 100 is also equipped with a fire door 168, which is located on the end frame 140 at the first end of the enclosure 100, so as to facilitate personnel to enter the fire compartment 104 to control and use fire equipment.

[0086] Optionally, refer to Figure 3 and Figure 4The energy storage box also includes a ventilation assembly 180, which includes a first fan 181 and a second fan 182. The first fan 181 is located in the electrical compartment 102 and connected to the battery compartment 101 via a second partition 161. The second fan 182 is located in the battery compartment 101 and connected to the outside of the box body 100 via an end frame 140 near the liquid cooling compartment 103. When the first fan 181 and the second fan 182 are turned on, an airflow is formed in the battery compartment 101 along the length direction D1 for ventilation. Furthermore, the first fan 181 and the second fan 182 are arranged at intervals along the width direction D2 of the box body 100, so that the airflow formed in the battery compartment 101 when the first fan 181 and the second fan 182 are turned on flows along the width direction D2, further enhancing the ventilation effect in the battery compartment 101.

[0087] Optionally, both the first fan 181 and the second fan 182 can be equipped with air dampers, so that the battery compartment 101 can be closed when the battery in the battery compartment 101 catches fire, thereby preventing the release of toxic gases from the battery compartment 101.

[0088] The following is combined Figure 5 , Figure 6 as well as Figure 8 The fireproof component 170 of the energy storage box according to this utility model will be described.

[0089] Optionally, refer to Figure 5 The fireproof component 170 includes a first fireproof layer 171, and the housing 100 also includes a first frame 169, which is connected to the inner wall of the battery compartment 101. Figure 5 The middle section is the side wall of the second partition 161, which can also be the side wall of the first partition 160 or the wall panel of the side frame 150. The first frame 169 is arranged between the first fireproof layer 171 and the inner side wall of the battery compartment 101. The first fireproof layer 171 is connected to the first frame 169 and the inner side wall of the battery compartment 101 by fasteners such as studs 174, thereby giving the inner side wall of the battery compartment 101 good fire resistance.

[0090] In addition, the first frame 169 can be constructed as a mesh frame structure with longitudinal and transverse distribution, which can effectively stabilize the first fireproof layer 171 and improve the structural strength of the inner wall of the battery compartment 101.

[0091] The batteries in the battery compartment 101 and the liquid cooling equipment in the liquid cooling compartment 103 or the electrical equipment in the electrical compartment 102 need to be connected by pipelines 192. The locations where these pipelines 192 pass through to the inner wall of the battery compartment 101 also need to be fireproofed.

[0092] Reference Figure 6Taking the battery in battery compartment 101 and the electrical equipment in electrical compartment 102 as an example, the energy storage box also includes a pipeline protection frame 190. The pipeline protection frame 190 extends along the length direction D1 to the second partition 161, and the first fireproof layer 171 of the second partition 161 near the battery compartment 101 covers the pipeline protection frame 190. The pipeline 192 passes through the pipeline protection frame 190 to the second partition 161, so that the pipeline 192 is protected by the first fireproof layer 171 and the pipeline protection frame 190 when it passes through the second partition 161, making it less likely to be damaged by flames in the battery compartment 101, thus improving the safety of the energy storage box. Furthermore, the pipeline enclosure 190 is also filled with fire-resistant mortar 191, so that the pipeline 192 passing through the pipeline enclosure 190 is wrapped with fire-resistant mortar 191, which not only stabilizes the pipeline 192, but also further protects the pipeline 192 and improves the fire safety of the energy storage box.

[0093] Optionally, a first frame 169 and a first fireproof layer 171 may also be provided on the top of the battery compartment 101 (specifically, the bottom surface of the top plate 123). The first frame 169 is connected to the bottom surface of the top plate 123 (the part located inside the battery compartment 101), and the first fireproof layer 171 is connected to the first frame 169 and the top plate 123 by fasteners such as studs 174, so that the top of the battery compartment 101 has good fireproof performance.

[0094] Optionally, refer to Figure 8 The fireproof component 170 includes a second fireproof layer 172 and a third fireproof layer 173. Along the height direction D3, the second fireproof layer 172 is laid above the base frame 110, and the third fireproof layer 173 is disposed below the intermediate longitudinal beam 114 and the second frame 115. In other words, the intermediate longitudinal beam 114 and the second frame 115 are disposed between the second fireproof layer 172 and the third fireproof layer 173. The second fireproof layer 172 and the third fireproof layer 173 are connected by fasteners such as studs 174, thereby forming two fireproof layers at the bottom of the battery compartment 101, further improving the fire safety of the energy storage box.

[0095] Optionally, the bottom sealing plate 117 is constructed with corrugated grooves 118. The corrugated grooves 118 are used to accommodate the portion of the third fireproof layer 173 covering the bottom of the second frame 115. Along the length direction D1, the corrugated grooves 118 and the second frame 115 are arranged one-to-one, so that the portion of the third fireproof layer 173 covering the bottom of the second frame 115 can be accommodated by the corrugated grooves 118, thereby ensuring the continuity of the third fireproof layer 173. In addition, the bottom sealing plate 117 adopts a corrugated plate structure (used to construct the corrugated grooves 118), which has high rigidity and can also ensure that it will not sag or deform without direct contact or fixation with the second frame 115.

[0096] Optionally, the first fireproof layer 171, the second fireproof layer 172, and the third fireproof layer 173 can all be fire blankets, which have good fire resistance and deformation performance and are easy to install.

[0097] This invention also provides an energy storage system, including the energy storage box described above. The energy storage system according to this invention is easy to install and has good heat dissipation performance.

[0098] Optionally, the energy storage system also includes batteries or battery packs, which can be installed in the battery compartment 101 of the energy storage box 100 via battery racks for storing electrical energy and have high fire safety.

[0099] Optionally, the energy storage system also includes electrical equipment installed in the electrical compartment 102, including combiner cabinets, high-voltage boxes, and other equipment, for controlling the charging and discharging of batteries or battery packs.

[0100] Optionally, the energy storage system also includes a liquid cooling device, which is located in the liquid cooling chamber 103. This eliminates the need for air duct devices and avoids occupying excessive space within the enclosure 100.
