Description
技术领域
本发明涉及动力电池防爆技术领域,具体涉及一种带有温控系统及灭火装置的动力电池防爆装置。
背景技术
随着交通运输业的蓬勃发展和汽车保有量持续攀升,无疑在方便人民生活的同时,也给能源和环境带来了严峻的挑战。
而在诸多研究之中,安全问题必然是要被优先考虑的。生活之中最危险的要数电器,而新能源汽车也是一个集成的“电器”,对于用电的安全还是要着重考虑的,尤其是电池问题,一旦爆炸将对使用者和整车造成不可估量的危害。
随着新能源汽车技术的逐步成熟和产业化,能够对动力电池进行改动并减少爆炸产生的危害,甚至防止爆炸的电池技术也在不断的发展和进步。目前动力电池防爆技术主要在实验阶段。如今电池内部的设计还是存在一定缺陷,当电池在充满电状态下,在存在缺陷处,电池温度上升、能量过剩,于是电解液分解产生气体,电池内压急剧上升而发生自燃或爆炸。或者是电池发生碰撞,造成挤压变形会发生爆炸。
而在目前二氧化碳灭火是最为广泛的,液态二氧化碳的存储条件高,但成本确实不高,且制作起来极为简便。液态二氧化碳一经释放,便迅速气化,吸收周围的热量达到降低温度的效果。就算面对突如其来的火势也能迅速灭火,而且灭火效果极佳,速度迅速。但其存储条件也很高,液态二氧化碳需要加压在耐压钢瓶中,且为一次性消耗品,所以只有在当温度达到电池燃烧点或者已经燃烧时才会使用。
发明内容
本发明提供了一种带有温控系统及灭火装置的动力电池防爆装置,以解决现有技术中不能对动力电池防爆效果差的问题。
本发明提供了一种带有温控系统及灭火装置的动力电池防爆装置,包括:电池箱体、二氧化碳存储钢瓶、温度控制组件、温度传感器、控制器;
动力电池设置于所述电池箱体内;所述二氧化碳存储钢瓶设置于所述电池箱体上部,通过管路与所述电池箱体内部连通;所述温度控制组件设置于所述电池箱体侧壁上,对所述电池箱体内的温度进行调整;所述温度传感器设置于所述电池箱体内;所述控制器分别与所述二氧化碳存储钢瓶上的气阀门、温度控制组件、温度传感器连接。
进一步地,所述电池箱体的上、下盖均可拆卸。
进一步地,所述温度控制组件包括:集热板、蛇形管路、加热器、制冷器;所述集热板贴合在所述电池箱体的侧壁上;所述蛇形管路铺设于所述集热板表面与所述制冷器连接;所述加热器设置于所述集热板上;所示控制器分别与所述加热器、制冷器连接。
进一步地,所述电池箱体的侧壁上开设有通气孔,所述通气孔通过弹性挡盖遮蔽。
进一步地,所述蛇形管路中的冷却液为机油。
进一步地,所述加热器为加热电阻。
本发明的有益效果:
本发明根据温度传感器的温度反馈,在电池箱体处于高温或已燃烧时,通过二氧化碳存储钢瓶中的二氧化碳进行降温或灭火,放置动力电池爆燃。本发明将电池箱体的上下盖设为可拆卸,可以方便快捷的更换电池。本发明通过在集热板上同时设置加热器、制冷器可以在起到温度控制的同时降低本发明装置的整体体积。本发明在电池箱体的侧壁上开设具有弹性挡盖的通气孔,可以在电池箱体内气压过大时,通过通气孔自动调节电池箱体内的气压,避免电池箱体因气压过大而爆裂。本发明借助电池本身发热,产生高低温差,增加空气流动的速度,在确保降低空气温度的同时,能够排除电池因化学反应所引起气体膨胀,有效降低电池内部压力,从而有效保护电池,提升车载电池使用寿命。本发明采用机油作为冷却液可以提高制冷效果。
附图说明
通过参考附图会更加清楚的理解本发明的特征和优点,附图是示意性的而不应理解为对本发明进行任何限制,在附图中:
图1为本发明具体实施例的立体视图;
图2为本发明具体实施例的中温度控制组件的结构图。
具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
本发明实施例如图1、2所示,提供了一种带有温控系统及灭火装置的动力电池防爆装置包括:掀盖1、固定弹簧2、电池箱体3、上端盖4、液态二氧化碳通入管道5、下端盖6、电子阀7、顶盖8、螺纹孔9、集热板10、蛇形管路11、制冷器12、二氧化碳存储钢瓶13,螺栓14、控制器17、充电接口18、加热器22、温度传感器。
动力电池设置于所述电池箱体3内;二氧化碳存储钢瓶13设置于电池箱体3的上端盖4外侧,通过液态二氧化碳通入管道5与电池箱体3内部连通;集热板10贴合在所述电池箱体3的侧壁上;所述蛇形管路11铺设于所述集热板10表面与所述制冷器12连接;所述加热器22设置于所述集热板10上,蛇形管路11中的冷却液为机油,加热器22为加热电阻;电池箱体的上端盖4、下端盖通过螺纹孔9与螺栓14配合实现可拆卸的安装;控制器17分别与所述二氧化碳存储钢瓶13上的电子阀7、加热器22、制冷器12、温度传感器连接;电池箱体3的侧壁上开设有通气孔,通气孔通过弹性挡盖遮蔽,弹性挡盖有掀盖1、固定弹簧2组合实现,固定弹簧2的回弹力设置由电池箱体3内最大可承受气压决定。
本发明具体实施例的的安装说明:
首先所述的带有温控系统及液态二氧化碳灭火装置的动力电池的上端盖4和下端盖6与电池箱体3通过上下各4个螺纹孔9连接,温度传感器通过胶水黏附在动力电池上,掀盖1固定在方形槽口处,固定弹簧2固定在掀盖1和电池箱体3上。
其次,将加热电阻22和机油冷却装置12固定在温度控制装置21的外壁上。
最后,将电池箱体3,温度控制装置21,控制中心17通过螺纹孔9,螺栓14紧密固定在下端盖6上。且所述连接均需密封处理。
本发明具体实施例的工作原理:
控制器17通过温度传感器判断当前动力电池的工作温度。当电池温度过低时,会影响电池容量,降低整车续航行驶里程,减少电池使用寿命。此时控制器17对加热电阻22通电,将集热板10进行加热,再均匀扩散到电池箱体3内,对温度较低的动力电池进行预热,使其所处环境温度上升。最后热空气通过电池箱体3前方的掀盖1被排出电池箱体3外。
当动力电池温度持续升高时,由于此时动力电池需要冷却,加热电阻22不工作,此时控制器17控制机油冷却循环启动,通过集热板10内部的蛇形管路11将集热板10相连的电池箱3中的热量带走,通过机油冷却装置12散热,从而实现使动力电池降温的效果。
当控制器17检测到动力电池达到燃烧温度或者动力电池已经燃烧,控制器17控制液态二氧化碳存储钢瓶5上的电子阀7打开阀门,使得液态二氧化碳经由管道5进入电池箱体3内,实现动力电池的快速降温或者灭火,防止进一步发生爆炸。
虽然结合附图描述了本发明的实施例,但是本领域技术人员可以在不脱离本发明的精神和范围的情况下作出各种修改和变型,这样的修改和变型均落入由所附权利要求所限定的范围之内。
