Embodiment Construction
[0043] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.
[0044] The battery pack in the prior art includes a casing and a cover on the casing, the space formed by the casing and the top cover is used to accommodate the battery module, and a liquid cooling device is provided between the casing and the battery module, The liquid cooling device is in contact with the module to improve the cooling effect. However, there are hidden dangers of liquid leakage at the interface, welds or seals of the liquid cooling device. When the liquid cooling device in the battery pack leaks, it will cause a short circuit of the power battery and accelerate thermal runaway, which will shorten the life of the battery and bring safety hazards...
