Summary:A battery pack according to one embodiment of the present invention comprises: a battery cell stack in which a plurality of battery cells are stacked; a battery module including a module frame for accommodating the battery cell stack, and a heat-sink located below the module frame; a pack refrigerant tube in which a refrigerant flows; a cooling port connected to a through-hole formed in the heat-sink; and a cooling connector for connecting the pack refrigerant tube with the cooling port. The cooling port includes an inclined part formed at the outer circumferential surface of the cooling port. The width in the horizontal direction of the inclined part gradually decreases in the direction in which the cooling connector is located. A ring-shaped sealing member is located between the inclined part and the cooling connector. Un bloc-batterie selon un mode de réalisation de la présente invention comprend : un empilement d'éléments de batterie dans lequel une pluralité d'éléments de batterie sont empilés ; un module de batterie comprenant un cadre de module pour recevoir l'empilement d'éléments de batterie, et un dissipateur thermique situé sous le cadre de module ; un tube de réfrigérant de bloc dans lequel s'écoule un fluide frigorigène ; un orifice de refroidissement relié à un trou traversant formé dans le dissipateur thermique ; et un connecteur de refroidissement pour connecter le tube de réfrigérant de bloc à l'orifice de refroidissement. L'orifice de refroidissement comprend une partie inclinée formée au niveau de la surface circonférentielle externe de l'orifice de refroidissement. La largeur dans la direction horizontale de la partie inclinée diminue progressivement dans la direction dans laquelle se trouve le connecteur de refroidissement. Un élément d'étanchéité annulaire est situé entre la partie inclinée et le connecteur de refroidissement. 본 발명의 일 실시예에 따른 전지팩은, 복수의 전지셀이 적층된 전지셀 적층체, 상기 전지셀 적층체를 수납하는 모듈 프레임 및 상기 모듈 프레임 아래에 위치한 히트 싱크를 포함하는 전지 모듈; 냉매가 흐르는 팩 냉매관; 상기 히트 싱크에 형성된 관통구와 연결되는 냉각 포트; 및 상기 팩 냉매관과 상기 냉각 포트를 연결하는 냉각 커넥터를 포함한다. 상기 냉각 포트는, 상기 냉각 포트의 외주면에 형성된 경사부를 포함한다. 상기 경사부의 수평 방향의 폭은 상기 냉각 커넥터가 위치한 방향으로 갈수록 좁아진다. 상기 경사부와 상기 냉각 커넥터 사이에 고리 형태의 실링 부재가 위치한다.
