Abstract: A cooler for at least one electrical energy storage element, the cooler comprising at least one heat-transfer liquid circulation duct, the ends of which penetrate into manifolds. Each of the manifolds comprises a collector having at least one opening for introduction and passage of at least one duct, and a cover covering the collector in such a way as to define a volume, into which the at least one duct opens, for circulation of the heat-transfer liquid. The at least one duct and the cover are mechanically assembled with the collector. A manifold further comprises at least one seal disposed between the collector and the at least one duct, and also between the collector and the cover.

Abstract: The invention concerns the cooler (1) for at least one electrical energy storage element, the cooler (1) comprising at least one heat-transfer liquid circulation duct (11) the ends of which penetrate into a manifold (41, 42), each of said manifolds (41, 42) comprising a collector (21, 22) having a through-opening (210) of said at least one duct (11), and a cover (31, 32) covering said collector (21, 22) in such a way as to define a volume for circulation of the heat-transfer liquid into which said at least one duct (11) opens. According to the invention, said at least one duct (11) and said cover (31, 32) are mechanically assembled with said collector (21, 22), said manifold (41, 42) further comprising at least one seal (51) disposed between said collector (21, 22) and said at least one duct (11), on the one hand, and between said collector (21, 22) and said cover (31, 32), on the other hand.
