[0002] As non-renewable energy is gradually consumed, the carbon emissions generated by the use of non-renewable energy have led to global warming. It is imperative to vigorously promote the development of renewable energy and transform the energy structure. While developing renewable energy such as wind power and photovoltaics, the proportion of fluctuating power generation due to its instability continues to rise. Therefore, in order to balance the relationship between power supply and demand, it is usually necessary to equip the renewable energy power generation system with a certain capacity of energy storage device, so as to play a role in peak regulation of the power station, promote the consumption of new energy and improve the quality of power.

[0003] Take the production of lithium batteries as an example. When injecting liquid, the electrolyte (lithium hexafluorophosphate, etc.) is injected into the battery according to the required amount through the reserved injection hole. Before injecting liquid, it needs to be baked at high temperature to bake the moisture to the range required by the process. The general baking temperature is 110℃, but the injection temperature should be controlled below 45℃ to ensure the stability of the electrolyte.

[0004] However, the traditional way to cool batteries is natural cooling, which has the following disadvantages:

[0005] ① Aiming at the shortcomings of traditional manual work, such as high labor intensity and unstable quality of cooling products.

[0007] ③ Reduce the drying and cooling time of the battery, which affects the production efficiency.

[0008] For this purpose, a closed battery cooling device is developed and designed. Utility Model Content
