Title
(EN) A DUCT AND A METHOD OF MANUFACTURING A DUCT
(FR) CONDUIT ET PROCÉDÉ DE FABRICATION D'UN CONDUIT
Abstract
(EN)
A battery pack comprises one or more cells 30, a flexible duct 50/230 positioned proximally to the surface of at least one of the one or more cells 30 such that heat can be exchanged between the duct 50/230 and at least one of the one or more cells 30 and a potting means which at least partially surrounds at least a part of the duct 50/230. A method of manufacturing a battery pack comprises providing one or more cells 30, positioning a flexible duct 50/230 proximally to the surface of at least one of the one or more cells 30 such that heat can be exchanged between the duct 50/230 and the at least one of the one or more cells 30, inserting fluid into the duct 50/230 and at least partially surrounding at least a part of the duct 50/230 with a potting means. The potting means may be expandable foam.

Un bloc-batterie comprend une ou plusieurs cellules 30, un conduit flexible 50/230 positionné de manière proximale à la surface d'au moins une cellule parmi la ou les cellules 30 de telle sorte que la chaleur puisse être échangée entre le conduit 50/230 et au moins une cellule parmi la ou les cellules 30 et un moyen d'enrobage qui entoure au moins partiellement au moins une partie du conduit 50/230. Un procédé de fabrication d'un bloc-batterie comprend les étapes qui consistent à fournir une ou plusieurs cellules, à positionner un conduit flexible 50/230 de manière proximale à la surface d'au moins une cellule parmi la ou les cellules 30, de telle sorte que la chaleur puisse être échangée entre le conduit 50/230 et au moins une cellule parmi la ou les cellules 30, à insérer un fluide dans le conduit 50/230 et à entourer au moins partiellement au moins une partie du conduit 50/230 avec un moyen d'enrobage. Le moyen d'enrobage peut être une mousse expansible.
