[0002] Lithium battery binders often require specific cooling devices during the production process to maintain their stable performance, especially during heating and curing or mixing reactions.

[0003] However, most existing cooling devices use natural air drying cooling, which results in a long cooling time, affecting work efficiency. At the same time, overheating of the adhesive will affect its physical and chemical properties, reduce its working performance, and lead to a decline in product quality.

A cooling device for the production of PMMA adhesive for lithium batteries can be designed, which utilizes the condensation outer ring on the outside of the storage barrel and the condensation inner tube in the fixed inner barrel to emit cold air, thereby increasing the heat exchange area and improving the heat exchange efficiency.
