Abstract
Embodiments of the present application relate to the technical field of batteries, and provide a water cooling assembly, a battery pack, and a device in order to solve the technical problem of low cooling efficiency of a cooling assembly of a battery pack. The water cooling assembly is configured to cool a cell, and includes: a body portion having a cooling channel for receiving a coolant; a first connecting portion connected to the body portion and having a communication cavity for introducing or draining the coolant; and a second connecting portion arranged between the body portion and the first connecting portion and having an inner cavity for communicating the cooling channel with the communication cavity. An end face of the inner cavity close to the cooling channel has a cross-sectional area greater than that of an end face of the communication cavity close to the inner cavity.
