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.
