[0019] The cooling assembly controls the cooling water to flow in through the first water inlet block 7 and the second water inlet block 8 and to flow out through the through plate.

[0020] like Figures 1-4As shown, multiple lithium battery bodies 11 are placed in the storage tank 6, and cooling plates 9 are provided between adjacent lithium battery bodies 11. The cooling water is controlled to enter the first water inlet block 7 and the second water inlet block 8 through the cooling assembly, and the first water inlet block 7 and the second water inlet block 8 are provided with positioning bars 12. When the positioning bars 12 are installed, it is convenient to stably fix the position in the storage tank 6. A channel is opened in the positioning bar 12. After the cooling water enters the first water inlet block 7 and the second water inlet block 8, the cooling water enters the first water inlet block 7 and the second water inlet block 8 through the first water inlet block 7 and the second water inlet block 8. The heat generated by the lithium battery body 11 is transferred to the cooling plate 9 when the lithium battery body 11 is working, thereby facilitating the heat dissipation of the lithium battery body 11 and ensuring that the lithium battery body 11 operates normally at a normal temperature. A box cover 2 is sealed and installed at the opening position of the storage tank 6 to prevent dust, water droplets and water vapor outside the box body 1 from entering the storage tank 6. The lithium battery body 11 can be conveniently protected to prevent dust and water droplets from contacting the lithium battery body 11 and ensuring the normal operation of the lithium battery body 11.

[0021] The bottom side of the positioning strip 12 is respectively provided with a first connecting head 14 and a second connecting head 15 above the first water inlet block 7 and the second water inlet block 8, and the first connecting head 14 and the second connecting head 15 can be respectively passed through the first connecting hole and the second connecting hole starting from the top side of the first water inlet block 7 and the second water inlet block 8; the bottom side of the positioning strip 12 is provided with a plurality of liquid inlet heads 13 that can be passed through the liquid inlet hole 10 opened on the top side of the cooling plate 9.

[0026] like Figures 1-4 As shown, when the water flows into the cooling pipe 19 under the action of the micro water pump 18, the water drives the linkage fan blades 22 to rotate, driving the water to flow in a spiral shape. When the spiral water flows through the multiple semiconductor refrigeration plates 23 arranged in the inner tube of the cooling pipe 19, the cooling end of the semiconductor refrigeration plate 23 is passed through the inner tube of the cooling pipe 19 to cool the water flow. The cooled water flow is then rotated and mixed by the mixing fan blades 21 driven by the control motor 20 to ensure the consistency of the temperature in the water flow. The cooling water is then introduced into the first water inlet block 7 and the second water inlet block 8 through the first connecting pipe 16.
