A storage device of a battery module is provided to have a simplified structure by integrating rectification fins with a housing, and to improve cooling performance of a battery module. A storage device of a battery module includes: a housing(10) which comprises outer walls(10a) installed at the right/left ends, inner walls(10b) installed between the outer walls away from each other, linking walls(10c) which horizontally link between the outer walls and the inner walls, and semi-circular through holes(14) formed on the upsides or downsides of the outer and inner walls or at the same positions facing the upside/underside, is formed by stacking and binding many layers together, and has divided bodies that form multi-divided flow space along the flowing direction of air; and rectification fins(16) which are protruded from the linking wall toward facing walls in predetermined length and covers a part of each longitudinally sectional area of the multi-divided flow space in the housing. |
