    摘要： The present application belongs to the technical field of batteries and provides a thermal management assembly, a battery, and an electrical apparatus. Among them, the thermal management assembly comprises: at least two fluid collecting tubes, and several fluid channels disposed side by side between the fluid collecting tubes wherein the fluid channel comprises two side faces disposed opposite to each other, one of the side faces being used for carrying the battery cell and for heat exchange with the battery cell, and the other one of the side faces being provided with an energy-absorbing structure, with the stiffness of the energy-absorbing structure being less than that of the fluid channels. When the bottom is subjected to an impact, the energy-absorbing structure will be damaged first to absorb and buffer the impact force generated by the impact on the bottom, so as to play the role of protecting the fluid channels.
