  • An advantage of the invention is to obtain a uniform temperature distribution at a moderate temperature level within a battery, a rechargeable battery or in general a charge accumulator, especially a lithium-ion battery. On the one hand, this is important for safety reasons, on the other hand it is possible to homogenize the cell characteristics, for example aging processes.

Abstract

L'invention concerne un dispositif de distribution de réfrigérants destinés au refroidissement de consommateurs, comprenant une conduite d'amenée commune (10) pour les consommateurs (14) et une conduite de retour commune (16), la conduite d'amenée commune (10) et la conduite de retour (16) comportant des dérivations (12) qui sont reliées aux consommateurs par des tronçons de tuyau ou des tuyaux. Entre au moins une dérivation (12) de la conduite d'amenée commune (10) et au moins un consommateur (14) est agencé un élément d'étranglement (18) pouvant être commandé. Une commande appropriée des éléments d'étranglement permet d'alimenter les consommateurs (14) en réfrigérant présentant des températures d'entrée identiques. Les consommateurs (14) servent par exemple à refroidir les éléments de batteries comprenant plusieurs éléments, par exemple au lithium-ion.
