The coolant formed by the water cooler 5 successively enters the battery pack 2 along the bottom surface and the left side surface of the first mounting rack 3 through the first water inlet pipe 7, achieving the cooling effect of the battery pack 2, facilitating the circulating flow of the liquid between the battery pack 2 and the water cooler 5, and cooling all the battery packs 2 on the first mounting rack 3. At the same time, the water in the overflow water kettle 9 enters the water cooler 5 through the water filling pipe 10, facilitating the rapid replenishment of the water consumed during the cooling process.

[0056] According to some embodiments of the present application, optionally, the first water inlet 21 of the battery pack 2 is connected to the first water inlet pipe 7 through the first connecting pipe 11, and the first water outlet 22 of the battery pack is connected to the first water return pipe 8 through the second connecting pipe 13.
