Immersed cooling energy storage battery pack

The immersed cooling energy storage battery pack provided by the invention comprises at least two rows of battery cell modules, a cooling liquid return pipe, a shell and at least one cooling liquid flowing pipe group, and each cooling liquid flowing pipe group comprises a cooling liquid shunting pipe, an inlet pipe and an outlet pipe. The battery cell modules are arranged in the shell side by side, and each cooling liquid shunting pipe is arranged between two rows of battery cell modules of the at least two rows of battery cell modules. Aiming at each cooling liquid flowing pipe group, a plurality of through holes are formed in the cooling liquid shunting pipe of the group, one end of the cooling liquid shunting pipe is fixedly connected with an inlet pipe of the group, the other end of the cooling liquid shunting pipe is fixedly connected to the rear wall of the shell, and an outlet pipe of the group is fixedly connected with a cooling liquid return pipe which is fixedly arranged between at least two rows of
