Liquid cooling assembly and battery

The utility model discloses a liquid cooling assembly and a battery, and relates to the technical field of batteries. The liquid cooling assembly comprises connecting pipelines and liquid cooling plates, the multiple liquid cooling plates are sequentially arranged side by side and connected between the two connecting pipelines in parallel, one of the two connecting pipelines is used for inputting cooling liquid to the multiple liquid cooling plates, and the remaining one of the two connecting pipelines is used for discharging the cooling liquid from the multiple liquid cooling plates. A telescopic pipe section is arranged on the part, between any two adjacent liquid cooling plates, of any connecting pipeline, and any two adjacent liquid cooling plates are used for respectively dissipating heat of two large surfaces of the same battery monomer. The liquid cooling assembly provided by the utility model is better in heat dissipation effect and higher in safety. 本实用新型公开了一种液冷组件及电池，涉及电池技术领域。该液冷组件包括连接管路及液冷板，多个液冷板依次并
