[0043] Working principle: Before use, the user can position the battery to be cooled at the upper and lower parts of the liquid cooling plate, and then dock the coolant delivery and outlet pipes with the two groups of docking pipes 4 respectively. When cooling the battery pack, the first heat exchange absorption plate 31 and the second heat exchange absorption plate 38 can quickly transfer the heat energy emitted by the battery pack, and then transfer it through the first heat exchange guide tube 310 and the second heat exchange guide tube 311. At this time, the three groups of first heat exchange guide plates 22 can be fitted with multiple groups of first heat exchange guide tubes 310 and second heat exchange guide tubes 311 through multiple groups of support slots 21 for heat exchange. At this time, the coolant inside the first heat exchange guide plate 22, the second heat exchange guide plate 24 and the third heat exchange guide plate 25 can be quickly diverted, thereby cooling the absorption plate 31 and the second heat exchange guide plate 38. The attached heat energy is quickly exchanged to improve the heat dissipation efficiency of the battery pack. If used for a long time, the first heat exchange guide plate 22, the second heat exchange guide plate 24 and the third heat exchange guide plate 25 need to be replaced.

At the same time, the first heat exchange absorption plate 31 and the second heat exchange absorption plate 38 can also buffer the heat exchange device 2 through the second spring guide shaft 312 and the first spring guide shaft 39, so as to improve the subsequent protection performance of the battery pack.
