Abstract

The present application provides a liquid-cooled BDU device and a battery pack, which relate to the field of battery technology. Among them, the liquid-cooled BDU device includes a shell and a liquid-cooled joint. After the shell and the liquid-cooled joint are sealed and connected by potting glue, a closed space can be formed, which can effectively isolate the entry of external water vapor, and then prevent the generation of condensed water, thereby avoiding electrical safety problems caused by condensation. A liquid cooling plate and a base are provided in the shell, and one side of the liquid cooling plate is fixedly connected to the base. Electrical components and current-carrying parts are provided on the base, and the base can fix the electrical components or current-carrying parts to each other, so that after the liquid cooling plate cools the base, the electrical components and current-carrying parts can be further cooled, thereby avoiding the electrical components and current-carrying parts from being degraded or damaged due to high temperature during operation.
