Battery heat dissipation device

Abstract

The utility model discloses a battery heat dissipation device which comprises a battery cell, a heat dissipation shell and a cover body, a supporting plate is fixedly connected in the heat dissipation shell and divides the interior of the heat dissipation shell into a lower air inlet chamber and an upper installation chamber, an air suction mechanism is arranged at the air inlet chamber, the interior of the installation chamber is divided into a plurality of installation cavities through partition plates, the battery cells are located in the installation cavities, and ventilation pipes are fixedly connected to the staggered positions of the partition plates. The battery pack disclosed by the utility model has the beneficial effects that the plurality of mounting cavities are formed through the partition plates, the heat-conducting silicon rubber cases are arranged in the mounting cavities, and the battery cells are mutually independent, so that heat accumulation caused by mutual contact of the battery cells is avoided; meanwhile, the battery pack is well protected by the high electrical insulation and anti-puncture performance of the silicon rubber case, and the air suction mechanism drives cold air to flow in the ventilation pipe to take away a large amount of air generated by the battery cells, so that the heat dissipation effects of the battery cells are consistent, and the temperature difference of the battery cells caused by non-uniform heat dissipation is avoided.
