一种防爆电池组箱
技术领域
本发明涉及电池组的安全领域,特别是涉及一种防爆电池组箱。
背景技术
随着能源和环境问题的日益严峻,在节能减排、绿色信贷、绿色证券等产业政策和市场的推动下,电动汽车正在渐渐地引起社会和政府的重视,电动汽车也将成为未来汽车行业的一大分支。电动汽车核心部件之一是电池组。而电池组的安全性能是决定该系统是否可用的关键技术。蓄电池在充放电的过程中容易产生较大的热量,这对蓄电池的使用寿命,以及安全性都十分的不利,现有技术中,电池组并没有针对起火、燃烧等突发情况配备相应的处理结构及措施,当电池组处于极端的工作环境下,由于短路、热失控等引起的电池组冒烟起火、爆炸、燃烧等现象时,常会导致电池箱体表面温度过高诱发电池箱体与整车附近的可燃物起火燃烧,从而导致电动车燃烧事故。
发明内容
为解决现有技术存在的问题,本发明提出一种降温效果好,使用方法简单,经济又实用且自动断电避免电池爆炸的防爆电池组箱。
本发明包括箱体和箱盖,所述箱体内壁设有注水层,所述箱体内设有散热板,所述散热板设有内腔,所述散热板分布在电池之间,所述内腔与注水层连通,所述箱体外壁设有进水口与出水口,所述进水口与出水口均与注水层连通。
进一步地,所述进水口位于箱体侧面顶部,所述出水口位于箱体底部。
进一步地,所述箱体靠近出水口的侧面内壁设有凹槽,所述凹槽内安装有热敏开关。
进一步地,所述凹槽内设有连通外界的通孔,所述热敏开关连接有穿过通孔的外接导线,所述热敏开关与电池连接。
进一步地,所述箱体与箱盖通过位置对应的磁钢进行连接。
本发明相对于现有技术,其优点在于:
1、本发明它包括箱体,所述箱体内壁设有注水层,所述注水层中可以容纳水也可以容纳工业冷却液,所述注水层连通有进水口和出水口,所述进水口设有循环水泵,这样的设计将注水层与电池完全隔开,提高了电池组的安全性,且扩大了与电池组的接触面积,便于冷却液体带走热量;箱体内设有散热板,散热板设有内腔,散热板分布在电池之间,内腔与注水层连通,散热板与电池组放置的电池列数相适应,能够起到很好的减震作用,且每块散热板都分布在电池组电池之间,增强了散热降温的效果,提高了散热效率,散热板的内腔与注水层连通,这样通过一个进水口即可对所有的散热板供水,结构十分简单。
2、本发明通过在温度较高的出水口处设置热敏开关,且热敏开关一端连接电池组电池,另一端连接外接导线,这样在电池组温度过高时,热敏开关断开,做到即时断电,防止电池组电池因为温度过高而爆炸,避免造成人员伤亡。
