Description

一种开放式浸没储能电池箱及其电池柜An open submerged energy storage battery box and battery cabinet thereof 技术领域Technical Field
本发明涉及储能电池领域，尤其是一种开放式浸没储能电池箱及其电池柜。The invention relates to the field of energy storage batteries, in particular to an open submerged energy storage battery box and a battery cabinet thereof.
背景技术Background technique
随着电化学储能系统的大规模运用，其安全性问题不容忽视。目前电池储能系统一般采用风冷和液冷板简介散热进行环境温度的控制，电池组之间温度较差或电池发生过充过放等问题时，电池容易发生热失控排出大量可燃气体并引发火灾，严重时甚至导致整个储能系统的爆炸，造成难以评估的损失。With the large-scale application of electrochemical energy storage systems, their safety issues cannot be ignored. At present, battery energy storage systems generally use air cooling and liquid cooling plates to control the ambient temperature. When the temperature between battery packs is poor or the battery is overcharged or over-discharged, the battery is prone to thermal runaway, emitting a large amount of flammable gas and causing a fire. In severe cases, it may even cause the entire energy storage system to explode, causing losses that are difficult to assess.
目前，类似数据中心采用的绝缘冷却液浸没冷却方式具有与散热效率高，温度均匀性以及灭火性能好，在储能系统的电池柜产品方面具有十分广阔的运用前景。但绝缘冷却液本身易挥发、比重大、价格较贵，接液材质具有兼容性要求。专利<CN114421054A>提供的一种液冷储能装置，其电池组全部浸没在绝缘冷却液的缸体中，绝缘冷却液用量十分巨大，缸体的密封、承压和均流设计要求高，整体造价较高，无法在同容量储能用电池柜产品方面取得较大的竞争优势。因此，本专利开发了一种开放式浸没储能电池箱及其电池柜。At present, the insulating coolant immersion cooling method used in similar data centers has high heat dissipation efficiency, temperature uniformity and good fire extinguishing performance, and has a very broad application prospect in the battery cabinet products of energy storage systems. However, the insulating coolant itself is volatile, has a high specific gravity, is relatively expensive, and has compatibility requirements for liquid contact materials. The patent <CN114421054A> provides a liquid-cooled energy storage device, in which the battery pack is completely immersed in a cylinder of insulating coolant. The amount of insulating coolant used is very large, and the sealing, pressure bearing and flow equalization design requirements of the cylinder are high. The overall cost is high, and it is impossible to gain a greater competitive advantage in battery cabinet products with the same capacity for energy storage. Therefore, this patent develops an open immersion energy storage battery box and its battery cabinet.
