Abstract

L'invention vise à fixer de manière fiable des batteries de forme rectangulaire respectives d'une manière stable tout en refroidissant de manière rapide et efficace les batteries de forme rectangulaire. A cet effet, l'invention concerne un dispositif de source d'énergie pour distribution d'énergie qui comprend : un bloc-batteries (3) dans lequel plusieurs batteries de forme rectangulaire (1) sont disposées en étant empilées ; une plaque de refroidissement (21) à la surface de ce bloc-batteries (3), disposée dans une condition de couplage thermique avec les batteries de forme rectangulaire respectives (1) et qui refroidit de manière forcée chacune de ces batteries rectangulaires (1) depuis la face inférieure de celles-ci ; et un mécanisme de refroidissement (20) qui refroidit cette plaque de refroidissement (21). Dans ce dispositif de source d'énergie, la plaque de refroidissement (21) est reliée à couplage thermique avec des faces de refroidissement (1X) constituant des faces inférieures ou des faces latérales des batteries de forme rectangulaire (1) et une couche de résine d'enrobage (9) est disposée à la face circonférentielle externe du bloc-batteries (3) ; de plus, cette couche de résine d'enrobage (9) comporte une section exposée (9X) par laquelle les faces de refroidissement (1X) des batteries de forme rectangulaire (1) sont exposées et les faces de refroidissement (1X) des batteries de forme rectangulaire (1) sont connectées à couplage thermique à la plaque refroidissante (21) au niveau de cette section exposée (9X).
