[0035] Specifically, since the water reservoir 20 is built underground, there is a large difference in temperature compared with the ground, when the backflow water returns to the water reservoir 20, the heat is dissipated to the surrounding environment through the heat conduction assembly 200, when the backflow heat and the dissipated heat are consistent, the water temperature of the water reservoir 20 and the temperature of the battery cluster assembly 30 can be kept constant.
