Battery module flame arrester design

The present invention generally relates to a flame arrester apparatus configured to reduce the hazard of thermal runaway by containing sparks and molten particles discharged from a battery cell as well as a cooling gas. The apparatus may be used in any device requiring a lithium ion battery unit, such as a data center, a smartphone, a tablet computer, an earplug, and the like. The apparatus may include a mesh screen and a baffle. The mesh screen may include a plurality of mesh layers offset from each other. The baffle plate can form a herringbone shape and is fixed on the inner side of the mesh screen. 本发明大体上涉及一种阻火器设备，该阻火器设备被配置为通过容纳从电池单元排出的火花和熔融粒子以及冷却气体来减少热失控的危害。该设备可用于任何需要锂离子电池组单元的装置，例如数据中心、智能电话、平板电脑、耳塞式耳机等。该设备可以包括网筛和挡板。网筛可以包括彼此偏移的多个网层。挡板可以形成为人字形图形并固定到网筛的内侧。
