Abstract
A heat absorbing device including a structure including plural individual cells delimited by an envelope made of a material that has good thermal conductivity and includes at least one phase-change material, the cells being stacked on top of one another from an end surface so that the structure extends in a direction of thermal flux, the flux being made up of two notable periodic thermal events, the structure including two different sizes of cells. The sizes of the cells are determined as a function of frequency of the thermal events of the thermal flux and a distribution of a number of cells of each size is determined as a function of amplitudes of each event.
