The invention belongs to the field of air-cooled batteries, and discloses a heat conduction cover plate for an air-cooled battery, a battery module and a battery pack. A heat dredging cover plate for an air-cooled battery is made of fireproof materials and comprises a U-shaped upper plate, a multi-bend lower plate and a transverse partition plate which are fixedly connected with one another, a spraying area, two evacuation areas and two cooling areas are formed, the two evacuation areas are symmetrically distributed on the left side and the right side of the spraying area, the spraying area and the evacuation areas are divided by the transverse partition plate, and the lower end of the spraying area is communicated with battery cell heat dissipation holes. The heat conduction cover plate is combined with a heat dissipation plate and a fireproof material which are fixed on the side surface of the battery cell to form a heat diffusion prevention structure of the battery module; a flame-retardant isolation plate is arranged between adjacent battery modules to control heat diffusion in the battery pack; the heat conduction cover plate has double functions of a heat conduction channel and an isolation cover plate, and the structural design of the battery module and the battery pack is simplified, so that the thermal runaway of the battery module and the battery pack can be effectively prevented, and the assembly process is simple, efficient and economical.

    本发明属于风冷电池领域,公开了一种风冷电池用热疏导盖板、电池模组及电池包。一种风冷电池用热疏导盖板,由防火材料制成,包括相互固定连接的U型上板、多折弯下板和横隔板,形成喷射区及对称分布在其左右两侧的两个疏散区、两个冷却区,喷射区、疏散区被横隔板分割,喷射区下端与电芯散热孔连通。热疏导盖板与固定在电芯侧面的散热板和防火材料组合,构成电池模组的防热扩散结构;相邻电池模组之间安装阻燃隔离板控制电池包内的热扩散;热疏导盖板具有热疏导通道和隔离盖板双重作用,简化了电池模组和电池包的结构设计,从而不仅能够有效防止电池模组和电池包的热失控,而且组装工艺简单,高效、经济。
