Abstract
A heat-transferring device is formed by a stack that includes at least one heat-conducting layer and at least one heat-absorbing layer. The at least one heat-conducting layer has at least one heat-collecting section placed facing a heat source and at least one heat-evacuating section placed facing a heat sink. The at least one heat-absorbing layer includes a phase-change material. One face of the at least one heat-absorbing layer is adjoined to at least one portion of at least one face of the heat-conducting layer.
