Abstract

Entretoise pour pack-batterie, destinée à séparer deux accumulateurs adjacents du pack et à permettre une circulation de fluide caloporteur avec contact direct avec les accumulateurs pour leur refroidissement optimal L’invention concerne une entretoise (1) pour pack-batterie (P), destinée à séparer deux accumulateurs électrochimiques (A1, A2, …) adjacents du pack et à permettre une circulation de fluide caloporteur en son sein. Elle consiste en une entretoise monolithique dont la géométrie permet d’assurer un contact fluidique direct avec les accumulateurs adjacents qu’elle sépare tout en assurant une répartition de la pression mécanique sur la surface principale de chaque accumulateur. Figure pour l’abrégé : Fig. 10Spacer for battery pack, intended to separate two adjacent accumulators from the pack and to allow circulation of heat transfer fluid with direct contact with the accumulators for their optimal cooling The invention relates to a spacer (1) for battery pack (P), intended for in separating two electrochemical accumulators (A1, A2, etc.) adjacent to the pack and in allowing heat transfer fluid to circulate within it. It consists of a monolithic spacer whose geometry ensures direct fluidic contact with the adjacent accumulators that it separates while ensuring a distribution of the mechanical pressure on the main surface of each accumulator.
