Abstract

La présente invention concerne un dispositif d'absorption et d'accumulation d'énergie calorifique, lequel est utilisé en particulier dans un accumulateur d'énergie. L'invention concerne en outre un procédé, lequel produit le dispositif ou une partie du dispositif. Le dispositif selon l'invention est constitué d'au moins un profilé extrudé, lequel est constitué d'une mousse métallique. Pour cet objectif, une mousse d'aluminium s'est révélée particulièrement avantageuse, l'invention ne visant pas à être limitée à de la mousse d'aluminium. La propriété de cette mousse métallique est que les pores situés dans la mousse sont remplis d'eau. Afin d'empêcher que l'eau ne s'écoule à l'extérieur, la surface du profilé extrudé est recouverte d'une couche de protection.
