Abstract

L’invention consiste à proposer un nouveau système de réfrigération magnétique opérant sur la base de l’effet magnétocalorique (emc) rotatif ou anisotrope. Dans ce système, le régénérateur (réfrigérant) est constitué de monocristaux magnétocaloriques orientés ou de matériaux magnétocaloriques texturés. Les effets thermiques nécessaires sont générés en faisant tourner le régénérateur (ou l'aimant) dans un champ magnétique fixe ce qui permet de rendre le réfrigérateur magnétique plus simple, compact et plus efficace. Dans ce cas, seulement une simple source de champ magnétique est nécessaire ce qui contraste avec les dispositifs magnétocaloriques rotatifs conventionnels. De plus, cette nouvelle architecture nous permet de bien maitriser les échanges thermiques entre le fluide caloporteur (eau, gaz) et le régénérateur en simplifiant drastiquement la conception du cycle thermodynamique de fonctionnement (cycle amr). Dans le but de réduire encore plus la consommation d'énergie associée aux mouvements de rotation du régénérateur (ou l’aimant), les efforts magnétiques en jeu peuvent être balancés (compensées) en divisant le régénérateur en deux blocs séparés. Les axes d’aimantation faciles des deux blocs sont initialement orientés suivant et perpendiculairement au champ magnétique appliqué, respectivement
