    Abstract: An energy storage cabinet includes a frame supporting multiple battery packs and a cooling device. The frame includes a support with a pipe and a partition dividing an internal fluid passage of the pipe into a first flow channel and a second flow channel. Each battery pack has a first vent and a second vent. The second vent of a first battery pack is in communication with the second flow channel. The first vent of a second battery pack is in communication with the first flow channel. The cooling device produces a cool air entering the first vent of the first battery pack and the first flow channel. As the cool air passes through the first battery pack, the cool air is heated and becomes a warm air, which is then discharged into the second flow channel through the second vent.
