Assembling shell of new energy electric vehicle battery

The utility model relates to the field of shells of automobile batteries, and discloses an assembly shell of a new energy electric automobile battery, which comprises a battery box body, a plurality of battery holes which penetrate through the height and are used for installing single batteries are uniformly formed in the end face of the battery box body at intervals, and a heat dissipation channel used for heat dissipation of the single batteries is arranged on the battery box body. Each battery hole can be provided with eight paths for dissipating heat towards the outer side through the heat dissipation channels, heat conduction and dissipation are faster, fins are arranged on the hole walls of the battery holes, gaps exist between the battery single bodies and the battery holes, heat can be conveniently conducted and dissipated outwards through air, heat conductors are further arranged in the heat dissipation channels, and heat dissipation efficiency is improved. The heat conductor can also conduct and dis
