The invention discloses a lithium battery protection device which comprises a main box body with a square box body structure; the heat dissipation bottom plate is arranged on the outer side of the bottom of the main box body; the heat dissipation bottom plate is provided with a heat dissipation aluminum plate, one end of the heat dissipation aluminum plate is provided with a front guide plate and a flow inlet, the front guide plate is located below the flow inlet, the front guide plate and the flow inlet are located on the same side, the other end of the heat dissipation aluminum plate is provided with a rear guide plate and a flow outlet, the rear guide plate is arranged above the flow outlet, and the rear guide plate and the flow outlet are located on the same side. A plurality of flow guide channels are formed in the heat dissipation aluminum plate at equal intervals, the diameter of each flow guide channel gradually decreases from the two ends to the middle, and the two ends of each flow guide channel communicate with the flow inlet and the flow outlet correspondingly. Through the design of the heat dissipation bottom plate, the heat dissipation effect in the main box body can be improved, all the lithium batteries can be protected while the main box body is broken off when the whole device is impacted, and the situations that the lithium batteries are broken off and packages are damaged are reduced.

    本发明公开了一种锂电池保护装置,包括,主箱体,主箱体具有方箱体结构;散热底板,主箱体的底部外侧设有散热底板;散热底板具有散热铝板,散热铝板的一端部设有前导流板和进流口,前导流板位于进流口的下方,前导流板与进流口位于同一侧,散热铝板的另一端部设有后导流板和出流口,后导流板设于出流口的上方,后导流板与出流口位于同一侧,散热铝板的内部等距开设有多个导流通道,导流通道的直径由两端部逐渐向中部减小,导流通道的两端部分别与进流口和出流口连通;本发明通过散热底板的设计,不仅能够提高主箱体内部的散热效果,也能够在装置整体受到撞击使主箱体在折断的同时,保护各个锂电池,减少锂电池折断及包装受损的情况发生。
