Description

Technical Field

[0001] This utility model relates to energy storage equipment, specifically to a fireproof composite board and an energy storage cabinet. Background Technology

[0002] Existing energy storage cabinets mostly use polyurethane foam, rock wool, and other materials as fireproof and heat-insulating materials. These cabinets generally have the following defects: 1. The cabinet body is made of a single layer of heat-insulating material such as polyurethane foam, which is prone to aging after long-term operation, resulting in a decrease in heat insulation performance of more than 30%; 2. Poor heat insulation performance means that if one battery pack goes out of control, a chain reaction will occur, leading to greater danger. In addition, to meet the fire resistance requirements of energy storage cabinets, the aforementioned fireproof and heat-insulating materials generally need to be 100mm or even thicker.

[0003] While using panels with thicker insulation layers can solve the above problems and enable the energy storage cabinet to meet the requirements of high fire resistance limits, the cabinet will also be larger and the cost will increase accordingly. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a fireproof composite board that can have a higher fire resistance limit without excessively increasing the thickness, making it suitable for use in energy storage cabinets.

[0005] To solve the aforementioned technical problems, the technical solution adopted by this utility model is as follows: a fireproof composite board, comprising a board body and a fireproof composite structure. The board body has an internal cavity containing a fireproof composite structure, which includes a flame-impact resistant layer and at least two heat-insulating layers. Each heat-insulating layer is composed of several aerogel heat-insulating sheets spliced ​​together, with each heat-insulating layer stacked sequentially on top of the flame-impact resistant layer, and adjacent heat-insulating layers interlocked. The fireproof composite structure within the cavity of the board body, comprising a flame-impact resistant layer and an aerogel heat-insulating layer, effectively improves the fire resistance and heat insulation performance of the board.

[0006] As an optional technical solution, the fire-resistant composite structure includes a flame-impact resistant layer, and a fire-resistant layer is provided on the end face of the panel body near the flame-impact resistant layer. This panel can provide fire and heat insulation on one side, making it suitable for use as a side panel, top panel, or bottom panel of an energy storage cabinet.

[0007] As an optional technical solution, the fire-resistant composite structure includes two flame-impact resistant layers, with a heat insulation layer positioned between the two flame-impact resistant layers, and fire-resistant layers on both ends of the panel body. This panel provides double-sided fire and heat insulation, making it suitable for use as an internal partition structure for energy storage cabinets.

[0008] As an optional technical solution, the fireproof layer is a fireproof coating layer.

[0009] As an optional technical solution, the aerogel insulation sheet is rectangular, with adjacent insulation layers being parallel and not completely overlapping. The aerogel insulation sheets are staggered and not completely overlapping, allowing for interlocking between adjacent insulation layers.

[0010] As an optional technical solution, the flame-impact resistant layer is an integral structural panel, avoiding seams through which flames can pass, thus enabling the panel to have better flame-impact resistance.

[0011] As an optional technical solution, the sheet body and the insulation layer, the sheet body and the flame-impact resistant layer, and the insulation layer and the flame-impact resistant layer are bonded together with high-temperature resistant structural adhesive.

[0012] As an optional technical solution, aerogel insulation sheets are composite panels made of high-content ceramic aerogel, glass fiber aerogel, or nano-aerogel.

[0013] As an optional technical solution, the flame-impact resistant layer is a ceramic fiber board, rock wool board, or mica board.

[0014] Based on the same concept, this utility model also provides an energy storage cabinet, wherein the side panels and / or top panels and / or bottom panels of the energy storage cabinet include the aforementioned fireproof composite material.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The fireproof composite board of this utility model has high fire resistance and heat insulation performance, which is suitable for energy storage cabinets. It can meet the high fire resistance limit requirements of energy storage cabinets without large thickness. Compared with existing single-layer heat insulation materials, it has better heat insulation performance and can effectively extend the aging time and reduce the danger. Energy storage cabinets made using the above-mentioned fireproof composite board have the advantages of good fire resistance and high space utilization. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figures 1-3 A fireproof composite board includes a board body 1 and a fireproof composite structure 2. A sandwich cavity is provided inside the board body 1, and the fireproof composite structure 2 is provided inside the sandwich cavity. The fireproof composite structure 2 includes a flame impact resistant layer 21 and a heat insulation layer 22. The flame impact resistant layer 21 is used to block flame impact, and the heat insulation layer 22 is made of aerogel material, which plays a role in heat preservation. Due to the excellent heat insulation properties of aerogel, the fireproof composite structure 2 combined with the board body 1 can effectively improve the fire resistance and heat insulation performance of the board body 1 without significantly increasing the thickness of the board body 1, making it suitable for use in energy storage cabinets.

[0025] The heat insulation layer 22 is composed of several aerogel heat insulation sheets 221 spliced ​​together. Each heat insulation layer 22 is stacked on the flame-impact resistant layer 21, and the adjacent heat insulation layers 22 are pressed against each other. The seams between the aerogel heat insulation sheets 221 of the heat insulation layer 22 are pressed by the aerogel heat insulation sheets 221 of another heat insulation layer 22. The seams between them are staggered, which prolongs the path of heat loss and achieves a better heat insulation effect.

[0026] Please see Figure 3 As an optional implementation, the aerogel insulation sheet 221 is rectangular, and the aerogel insulation sheets 221 of two adjacent insulation layers 22 are parallel to each other and do not completely overlap. The surface of each aerogel insulation sheet 221 is pressed against the corresponding seam of another insulation layer 22. Figure 3 In the embodiment shown, there is a 90° angle between two adjacent aerogel insulation layers 22, which enables the sealing between adjacent insulation layers 22.

[0027] The aerogel insulation sheet 221 can be a sheet-like aerogel in the form of high-content ceramic aerogel, glass fiber aerogel, or nano-aerogel composite board. The flame-impact resistant layer 21 can be a ceramic fiber board, rock wool board, or mica board, etc. The flame-impact resistant layer 21 is an integral structural board to avoid seams that allow flames to pass through.

[0028] The sheet body 1 and the heat insulation layer 22, the sheet body 1 and the flame-resistant layer 21, and the heat insulation layer 22 and the flame-resistant layer 21 are all bonded together by high-temperature resistant structural adhesive 4.

[0029] Please see Figure 1 In some embodiments, the fire-resistant composite structure 2 includes a flame-impact resistant layer 21, with each heat-insulating layer 22 stacked on top of the flame-impact resistant layer 21. The layers combine to form the fire-resistant composite structure 2. The fire-resistant composite structure 2 is inserted into the interlayer cavity of the panel body 1 and bonded to the panel body 1 to form a fire-resistant composite panel. A fire-resistant layer 3 is also provided on the end face of the panel body 1 near the flame-impact resistant layer 21, which can further improve the fire-resistant effect of the fire-resistant composite panel. This fire-resistant composite panel is suitable for use as a side panel, top panel, or bottom panel of an energy storage cabinet. The end face where the fire-resistant layer 3 is located is the inner end face facing the inside of the energy storage cabinet, providing fire protection and heat insulation for the interior of the energy storage cabinet.

[0030] Please see Figure 2 In other embodiments, the fire-resistant composite structure 2 includes two flame-impact resistant layers 21, with heat-insulating layers 22 stacked between the two flame-impact resistant layers 21. The layers are combined to form the fire-resistant composite structure 2. The fire-resistant composite structure 2 is inserted into the interlayer cavity of the plate body 1 and bonded to the plate body 1 to form a fire-resistant composite plate. Fire-resistant layers 3 are provided on both ends of the plate body 1. This fire-resistant composite plate is suitable for use as a partition plate separating battery compartments inside an energy storage cabinet, providing both fire resistance and heat insulation for the battery compartments on both sides.

[0031] The fireproof layer 3 is a fireproof coating layer formed by applying fireproof coating.

[0032] Example 2

[0033] Energy storage cabinets, such as Figure 4 As shown, the energy storage cabinet uses the fireproof composite board described in Example 1.

[0034] Specifically, the energy storage cabinet includes a side panel 5, a top panel 6, and a bottom panel 7. The side panel 5 and / or the top panel 6 and / or the bottom panel 7 include fire-resistant composite materials, and the fire-resistant composite structure 2 of the fire-resistant composite materials includes a flame-impact resistant layer 21. The inner end face of the fire-resistant composite materials is provided with a fire-resistant layer 3. The side panel 5 can be one or more of the front panel, rear panel, and side panel.

[0035] An observation window or other structure can also be installed on the side panel 5 of the energy storage cabinet.

[0036] As an optional implementation, the energy storage cabinet also includes a partition plate 8. The partition plate 8 is set inside the energy storage cabinet and forms multiple battery compartments inside the energy storage cabinet. The partition plate 8 can be made of ordinary board or fireproof composite board. In the fireproof composite board used in the partition plate 8, the fireproof composite structure 2 includes two flame impact resistant layers 21, and fireproof layers 3 are provided on both ends of the fireproof composite board.

[0037] In this embodiment, the fireproof composite board adopts a standard size and has a thickness of about 20mm. When assembling the energy storage cabinet, it can be directly embedded into each structural plate of the energy storage cabinet. The assembly process is simple. Compared with the energy storage cabinet that uses 100mm thick rock wool board as fireproof and heat insulation material, the fire resistance performance of the energy storage cabinet in this embodiment can be improved by 60% (tested in accordance with GB / T 9978 "Fire Resistance Test Method for Building Components").
