Abstract

L'invention concerne un boîtier de batterie, comprenant : une plaque d'échange de chaleur (1) ; un cadre inférieur (2) comprenant un cadre de délimitation (21) préserntant une circonférence fermée disposée sur la plaque d'échange de chaleur (1) ; et une pluralité de premiers éléments de fixation (3A) disposés sur la circonférence du cadre de délimitation (21). La surface inférieure (211) du cadre de délimitation (21) comprend une première surface de contact (211A) et une première surface sans contact (211B) ; la surface supérieure (11) de la plaque d'échange de chaleur (1) comprend une seconde surface de contact (11A) et une seconde surface sans contact (11B). La première surface de contact (211A) et la seconde surface de contact (11A) sont proches de l'extérieur du cadre de délimitation (21), la première surface de contact (211A) et la seconde surface de contact (11A) étant en contact l'une avec l'autre. Les premiers éléments de fixation (3A) pénètrent à travers la plaque d'échange de chaleur (1) et le cadre de délimitation (21) au niveau de la première surface de contact (211A) et de la seconde surface de contact (11A) pour fixer la plaque d'échange de chaleur (1) au cadre de délimitation (21). La première surface sans contact (211B) et la seconde surface sans contact (11B) sont proches du côté interne du cadre de délimitation (21), et sont séparées l'une de l'autre dans le sens du haut en bas (Z) pour former une première rainure de réception (G1), la première rainure de réception (G1) étant un anneau sur la circonférence du cadre de délimitation (21). Le boîtier de batterie comprend en outre un premier élément d'étanchéité (4A), le premier élément d'étanchéité (4A) étant un anneau sur la circonférence du cadre de délimitation (21) et étant logé dans la première rainure de réception (G1) de façon à sceller la pluralité de premiers éléments de fixation (3A) depuis le côté interne du cadre de délimitation (21).
