Heat conduction structural member, battery module and battery pack

The utility model belongs to the technical field of battery packs, and provides a heat-conducting structural member, a battery module and a battery pack, the heat-conducting structural member mainly comprises a body made of a heat-conducting material, one side of the body is provided with a plurality of mounting grooves into which tab edge sealing positions of soft package battery units extend, the shape of the mounting grooves is matched with the shape of the tab edge sealing positions, and the tab edge sealing positions are arranged in the mounting grooves. And the plurality of mounting grooves are arranged along the length direction of the body. According to the scheme, the heat dissipation efficiency of the tabs of the soft package battery unit can be effectively improved, the temperature difference of the soft package battery unit is reduced, and the heat management capability of the battery is improved. In addition, the heat conduction structural member can also enhance the strength of the tab edge seal
